Visual Basic :: Dynamic Forms

Dynamic Forms?
Hi,

Not sure if this has been asked before, so sorry if it has.

Is it possible to open a form, if you know the name.
I'm trying to code a dynamic form, which relies on some input (database),
And because I would like most of the buttons not exist at design time,
it makes it hard to code it when they are based off a database input,
is there anyway to open a form, if you have say the form's name as a string?
Or am I just trying to do something which isn't possible in Visual Basic 6.

Thanks inadvance,

Dynamic Forms ?
Hi I'm basically a noob at VB, but not a noob at programming

Im making a small database, which you can browse some info in.
There is some text in it, and paths to images.

From a select statement, a random amount of items(images) might be selected, and I want to show all of those on screen, with the text.

THe problem is that froms seems to be static. So I must decide how many images can be shown on a form from the beginning?
What do I do to show 10 OR a 100 images ? And if there are a hundred (they dont fit on screen, so a scrollbar on the side would be nice, So it adjusts itself dynamically).

My humble thanks for any help !

Dynamic Forms
Hi all,

I'm totally new to VB (do know ASP though) so please forgive my stupid questions....

I want to build a form that will mostly have textboxes and dropdowns on it. The amount of textboxes however will depend on what the user selects.

So, the user selects (from a dropdown) the number 5... I now want to display 5 textboxes. If he then selects a different value, lets say 11, I want to display 11 textboxes

In ASP I would just do a loop and
response.write <input type="text" name="T1" size="20">
but I dont know how to do it in VB

Hope this is clear enough.

Thanks,
NN

Dynamic Forms Help Pls
I am building an application that accesses various tables in a database - my question is :

Is it possible to create a generic form and pass params to it like, what table in the database to display or a recordset, then dynamically insert the fields on the form relative to the fields in my db table or recordset? Previously I have worked with asp doing something like:

for each field in rs.fields

response.write ("<input type=""" & rs(Field) & """ name=""T1"" size=""20"">")

for a text field. Likewise for combo or listboxes etc.

If I can do this presumably I can keep the size of my application down as I will not need a form for each view of my database.

Thanks in advance

Dynamic Forms
I am trying to create a user form dynamically. Basically depending on the relevant fields i will display combo's, textboxes other controls based on the information from the database. Has anyone done this before or could recommend the best way to do it,

Thanks

Hi,
I want to generate Forms at runtime, the way I do it with controls

Is there a way, when I don´t know how much forms I need at runtime ???

Thanx and regards

Dynamic Controls On Forms
What is the best method for changing controls on forms? What I'm trying to do:

I've got a list box, and based on what the listbox is set to, textboxes, checkboxes etc will be needed for the user to enter data.

Different items in the listbox will require different controls but they need to appear in the same general area.

Do I just move them in code and make them invisible when not in use?

This seems code intensive? can I but these in a fram and do something similiar?

Any better ideas?

Dynamic Arrays And Forms
HI

in 1 form i dimmed callers() as insteger

Dynamic Forms And Event Handling
Hi,

I am trying to make an app that can dynamically build up question and answer form on the fly, so that a user can select the type of question and answer (textbox, yes/no radio button, multiple choice checkboxes, etc), type in the details, then click a button and it will generate a preview of the question that they just generated below.

Now what I want to be able to do is allow the user to click on one of these dynamically generated elements, for instance, a radiobutton, and then an action will be carried out. For instance, I would like the user to be able to click on one of the "yes" radiobuttons, and then a textbox somewhere appears or disappears, that sort of thing.

I imagine this will need to be done by adding event handlers, but I'm really lost and can't find a good example. I just want to be able to go to a particular function when a mousedown event occurs, and be able to tell who the sender was.

Any help would be greatly appreciated. It's sending me nuts!

A Problem: Dynamic Forms Have The Same Names.
When I create forms dynamically, the new created forms have the asme names, so I can't differ them in my codes (I should set the TAG property of my forms instead the form names)

I create dynamic forms usign this method:

VB Code:
Dim frmNewForm As FormSet frmNewForm = New Form1frmNewForm.show

is there any other method to create forms with different names?
Thanks a lot

Dynamic Forms And Setting Owners
Whee, fun stuff here.

After pawing through many samples of "SetParent", I decided to ask on the forums.

Here is my application:

I have a "control program", who's sole purpose is to load other mini-programs. The mini-programs (.DLL files), consist of a class module, and a form. The control program uses a CreateObject command to load the DLL, then a few CallByName's to execute methods within the DLL to return the hWnd of the form.

I then want this form contained within a picturebox control (or any container control) on my control program.

If this didn't make any sense, that's because I've been up too long trying to figure this out. Please let me have some feedback on what you think may help me here. If you need more information, please feel free to contact me however you can.

Thanks!

Form To Form Interaction Problem. (dynamic Forms)
Hello,
I have a form (MAIN) which is duplicated during runtime using

Dim X As Form
Set X = New MAIN
X.Show

"MAIN" contains functions, which trigger events for that form. My problem is, I have another form "TOOLS" which needs to interact with the "MAIN" from which it was launched. So far, "TOOLS" interacts only with the first "MAIN", and not with the one it was launched from. I know I could make "TOOLS" a user control and place it within "MAIN" so that it will work, but I prefer to have "TOOLS" be a single form. Any ideas on how I could solve this with ways to reference the form from which "TOOLS" was launched to where I can interact with it will be much appreciated.

Thank you ahead of time

Dimensionalized Dynamic Array Copied To A New Array Is No Longer Dynamic
I have a user-defined object DS, with a child used-defined object l() which is a dynamic array.

At some stage, I ReDim DS.l(x) where x is any positive integer and use the array.

I later do Let tempDS = DS and try to use the tempDS object and its property .l() in the same way. I'm trying to subsequently ReDim tempDS.l(y) ... but it doesn't work because the tempDS.l object was created as tempDS.l(x), not tempDS.l()

How can I make tempDS.l be created as l() and not l(x) when created by copying DS.l(x) ?

Script Control, Dynamic Control Creation, And Dynamic Control Events
Hey everyone.

I have been messing around with the Scripting Control and Dynamic Control Creation.. I think it's amazingly powerful to have a program that can be extended by an end user by using VB Scripting commands.  I'm actually developing a system that will allow scripts to be written, saved, and run on start-up of my program to create any additional forms or controls that end users have created so it is as if they have been there the whole time.

My problem is this:

I am creating controls as follows:

I Created a class ScriptingFunctions and added some functions to it, instantiate the class, and add the object to the ScriptControl so that i can have full control of the functions.

I run a function called AddObjectToForm(ByVal sFormName as string, byVal sObjectType as string, ByVal sObjectName as String).

It loops through vb.forms, finds the form with the name you sent, selects it, and does the following:

   frmForm.Controls.Add sObjectType, sObjectName

I then call, from script, a function already in the form called "GiveAccessTo" which adds the object with the form name as a prefix to the ScriptControl.. so if I just created a "Vb.CommandButton" with name "cmdNew", I can access it through the scripting control now using "frmFormcmdNew.Caption = "NewCaption""

My problem is, however....

How can I add code .. through the scripting control, for the events on the new control I just created?

I could see creating a new windowproc in the scripting control and doing a SetWindowLong w/ GWL_WNDPROC to subclass the window procedure, but I'm not sure what I would have to do with the function?  Should I have a MsScriptControlCTL.Module and add the function to that, and reference that function via AddressOf to get the pointer to that function?

Don't forget, I know when the program ends, all of this will go away, but Like I said, I plan to have the script saved so it will execute on startup.

I'd really appreciate any help anyone could give me on this.

Thanks a lot in advance! :)

Convert Outlook Template Forms (*.oft) To Access Forms - Is This Possible?

Getting List Of ALL Forms In A Project (including Unloaded Forms)
I'm trying to build a 3-tier template-project. In this template-project each user will be able to customize their environment. The admin specifies the default UI and the users can customize it.

Problem is, whenever we add a new form in this project, we'll need to change our UI customizer code.

For example, a user may have the option to set 'Starup Form' by a SetStartupForm() method. When we add a new form in our project, we'll need to add the form's name in that method.

Q. Is there any way to get name of ALL forms (loaded or unloaded) in a project ? I'm looking for something like:

VB Code:
Dim f As FormFor Each f In Project1.AllForms 'list of ALL forms cboStartupForm.AddItem f.NameNext

(They couldn't resolve it in CodeGuru. I have exactly same question. I hope someone can show me the correct path.

Problems Sizing Child Forms In Midi Forms
Hello

I have created midi form and some child forms. When l display the child forms they are automatically sized in proportion to what the midi form is. For example in design mode of the child forms l would like to make them a certain size. But if l resize the midi form and then excute the program the child forms will automattically resize in porportion to what the midi form has been changed to.

Is there a property that needs to be set, or is this a bug with Visual Basic 6 (sp5)

Many thanks in advance

Error While Closing All Forms Upon Exit Using The Forms Container
Hello,

I'm, Steve, a Jr. VB 6.0 Programmer with about three months of self training. I am supporting an application in which there are no other VB developers here. My decade plus of development and support has been in COBOL. I am receiving an error when exiting the application. The error is:

Err = 5
Err.Description = Invalid procedure call or argument

I have traced this the following line of code in
Sub Routine MDIForm_QueryUnload:

Forms(intFormToClose).SetFocus

One reason that this occurs is after an empty row is added to an MSFlexGrid.

While in the VB Debugger, Forms displays (4) separate Items. I'm not sure what to look for when I expand these Items. I can only see three open forms on my screen. The code then starts to close each Form starting with the highest Form number. When the
Forms(intFormToClose).SetFocus code is executed for what I think is the MSFlexGrid created as an instance of the Form it is part of, which is also part of an SSTab, the Err = 5 with an error description is displayed in a message box. The message box code was written by the previous
Programmer(s).

If none of this makes any sense, I understand and I thank you for reading this far.

If this does make some sort of sense, does the MSFlexGrid have to be closed before the Sub Routine MDIForm_QueryUnload starts?

Thanks in advance for any and all help,

Need Behaviour Of Normal Forms Similar To Child Forms In An MDI
Hi,

I have a problem and Iam unable to resolve it. If you could just give me the code for it..I would be very grateful..

Problem
----------

I have an MDI form, a child form
I have a reference to a DLL which has a normal form added
I have called the dll from the toolbar button of the MDI
The form pops up
When I click outside the form, it goes behind the MDI
I tried setwindowpos, the form stays on top..and I was happy
But alas...when I click on any other open application or invoke one, the form still stays on top and is a nuisance
I would like to see this work exactly like a child form
I tried getactivewindow and some more APIs but didn't succeed
Also when maximising , it should behave like the child form

Please could you resolve this and get me the code?

Thanks a lot in advance

Loading Dynamic Menus Within Dynamic Menus
We have a situation where some of our menus have become extremely long (upwards of 50 items) and are becoming unusable as a result. I've been asked to checnge our menu program so that, if there are more than 15 items it will group them into sub menus. Sound reasonably easy but I just can't quite seem to do it. I've been able to group the first 15 together by using the following algorithm:-

VB Code:
while moreRowsToAdd 'this is actually a while not eof statement against a recordset fnCreateMenu(rcsTmp("description")) 'this dynamically loads a menu item and returns it Let intMenuCount = intMenuCount + 1 If intMenuCount = mconMaxToolbarMenuOptions Then 'we need to add a sub menu and move all of the last 15 items onto it 'or we need to add a new menu at this level and continue to load into that one For lp2 = 1 To mconMaxToolbarMenuOptions 'get the new sub option menu Set mnuTmp2 = fnGetSubMenuItem(lp2) 'this routine loads a new sub menu item dynamically and returns it. 'get the existing menu Set mnuTmp = fnGetMenuItem(lp2) 'copy the details across Let mnuTmp2.Caption = mnuTmp.Caption 'unload the existing (and now unwanted) menu Unload mnuTmp Next lp2 Set mnuTmpHeader = fnGetMenuItem(intXpos, intYpos, 0, False) Let mnuTmpHeader.Caption = "Page 1" End Ifwend

So my menu structure at design time is to have an indexed menu item with an indexed sub menu item below it. Under normal circumstances it just dynamically loads as many menus as it needs. It always leaves menuItem(0) as blank and then hides it later in the program.

However, if it reaches 15 menu items it then starts loading sub menu items and copying the details of the current 15 menu items across. It then unloads the menu items as it no longer need them and renames menuItem(0), which now contains the 15 sub menu items, to "Page 1". This is fine and working so far.

The problem is that the next 15 items need to be loaded into Page 2, then Page 3 and so on. I can't seem to achieve this because Page 2 would presumably equate to menuItem(1), page 3 to menuItem(2) and so on. But at design time subMenuItem(0) can only exist in one place, i.e. under menuItem(0). So if I just keep loading subMenuItems they all appear under Page 1 which defeats the point of doing this in the first place.

I've tried creating menuItem(0) to menuItem(9) at design time and then creating subMenuItem0(0) to subMenuItem9(0) under them respectively but, since I need to do this with several menus, I eventually reach the point where VB reports tha I can't create any more controls on the form.

Does anyone have another suggestions?

MDIform, Child Forms, Non-MDI Forms, Focus?
I have an MDI form with some child forms. I also have a non-MDI form that can popup for non-modal messages. When the focus shifts from the MDI child form to the non-MDI form and then back to the MDI child form the MDI parent form gets the deactivate and activate messages. The problem is that the control that had the focus on the child form does not get it back. The focus seems to be set to the first control on the form. Is there an easy way to fix this? The controls are dynamically created by the program, so I need to be careful to not set focus on a non-existent control.

Center Child Forms Inside MDI Forms...
Just one quick question from geniuses out there... Does anybody know how to center a form inside an MDI form?

Forms In Forms && Button Image Questions?
Hello- I'm just picking up programming again from a long hiatus (commodore64 and Amiga days), so sorry if my questions are silly:

I need to put forms inside of forms via button click. I'm aware that I must make the main form a parent form by a true statment in the properties. The rest I don't know. My books on VB.net won't arrive for 3 or 4 days yet and I need to make progress also my forms will go about 3 or 4 forms deep before they reach a input/calculation type form...Help!

The other info I need is how (if possible) do I make a separate image appear when the mouse is over a button and another image when the button is clicked...so that's total of three images on a button (counting an original image.)

thx-
Eric

Good Techniques- More Forms Or Reuse Forms ?
hi all,
I am developing a front end in VB6 ...I have certain forms that have almost the same controls (text boxes, buttons etc.) but the functionality of the new form will vary. For instance the behavior of a button click will vary..or it may have an extra checkbox etc.

I need expert advise on which is the recommended approach

APPROACH 1:
Create a separate form for each individual functionality. This produces cleaner and simpler code, easy to understand and debug and free from undesirable effects of the reusable forms.

APPROACH 2:
Use the same form and add functionality to it...flags may be used to decide how the form behaves...for example depending on a certain boolean flag i can decide what the button click event does.
This produces complex and messy code. On the other hand, since I've heard that VB loads all the forms at run time, this will have a smaller memory foot print (due to less number of forms) and would make the application run faster.

APPROACH 3:
Try to combine the best of the above two approaches..i.e. use a separate form for each functionality to produce cleaner code. Then in the main forms Load event, immediately unload all the forms that are not needed...loading them explicitly through code as needed.
This way the memory usage for the code will be smaller and the code will run faster...

I may be wrong in certain of my assumptions above...and thats why this post..please correct me and help me decide the best approach for my code.

Thanks.

PS If I'm not clear in my explanation please post..and I'll try to explain it better.

Printing From A Forms Textbox To A Different Forms Label
Well i have a problem, i have no problems printing labels that are on other forms but i do with text boxes...

lets say i have form1 and form2 on form1 i have a textbox (txtBox) then on form 2 i have a label (lblLabel) i want to print the content of txtBox in lblLabel how do i do this if possible? do i have to store it in a variable before i take it across to print?

Problem With Forms And Setting Focus In The Forms
I have 3 forms in my project , the main form is acting as the listening post for my winsock controls that allow multi connections.
The other two forms are activated depending on the data recieved on the data arrival event of my listening winsock port.

This winsock form is listening for barcodes that are scanned in and sent to my winsock server. In the data arrival event I determine what the barcode is and this is done because the barcode will say something like this:
Bin00678
or
Mat00456

so first of all I get the type of thing scanned in , is it a material code or a bin code , determining this will fire which form to use for the data entry. I read the first three digits of the bar code to see if it is a bin or a mat , depending on which it is I then show the next form , either frmMaterial or frmBin

code:
Private Sub sckAccept_DataArrival(Index As Integer, ByVal bytesTotal As Long)

Dim sData As String
sckAccept(Index).GetData sData

sScanData = Mid(sData, 1, Len(sData) - 2)

If InStr(sScanData, "Box") Or InStr(sScanData, "Bin") Then
IntContainerScanned = 1
frmBin.Show
End If

If InStr(sScanData, "Mat") And IntContainerScanned = 1 Then
IntLocationScanned = 1
frmMat.show

So now if the data arrival event determines that the data sent has a Bin at the start we must now show the frmBin form. On this form I wish to straight away load the data recieved into the first text box on this form.

There may be 1 bins being scanned in or there may be 10 being scanned in. I have now set up a global variable in a code module that holds the data scanned in called sScanData

I have this code in the form activate event

Private Sub Form_Activate()
Dim i As Integer

i = 0
TxtContainer(i).SetFocus
TxtContainer(i).Text = sScanData
i = i + 1
TxtContainer(i).SetFocus
Txtlocation.Enabled = False
TxtPcode.Enabled = False

What I am trying to do is have the data scanned in go to the first text box on frmBin ( which it does ) then I want the focus to go to the next text box , I have 10 text boxs in a control array called txtcontainer. The frmBin never seems to become unactive even when the new data arrives in the winsock main form. This is my problem , how do I make the next data arrival go in the next text box in my control array , what is the trigger to do this , it cant be form active as it is already active. Im getting in a real mess here and can't see the wood for the trees

can you help ?

Re-usable Forms: Several Forms On Runtime, Same Source
Hey!

I've got a question (yet again): Is it possible to design one frame, but calling it several times (resulting in several open windows)? For example, a property-form. I got the code and a lot of stuff with properties. Now I want to load my property-form to show the actual item.

But then I want to compare that item with another one, so I need both properties at hand. form1.show won't do, because this would replace the first form. So is there another method to call forms? Like callForm(ID,caption,owner) or something?

Thank you!!
