Prevent User From Entering Values Into Combo Box


hey all...i designed this code a couple of months back while doing my IT school project, in order to prevent the user from entering any values into the combo box other than the values in the list. I have taken much from VBForums..so i think its the smallest thing I can do


VB Code:
Private Sub combo1_Change()'The following code is to prohibit the user from entering anything that is not an item in the list of the combo boxDim num As Longnum = combo1.ListCount - 1 'giving the variable [num] the value of the combo box;s list count (number of items in the list) minus 1Dim txt As Stringtxt = combo1.Text 'giving the variable [txt] the text in the combo boxFor i = 0 To num 'looping from 0 to num    combo1.ListIndex = i 'assigning the list index to the value of [i]    If combo1.Text = txt Then 'check if the text entered matches the item in the list        combo1.Text = txt    Exit Sub    Else    combo1.ListIndex = -1 'assigning the list index a value of [-1] in order to    'make the text in the combo box as ""    End IfNext iBeepEnd Sub


Hope someone finds it useful

Prevent User From Entering Pipes Into Textbox
I have a textbox that I don't want to allow Pipes to be entered in.
I am using the keyup event and I know how to figure out when the user hits the Pipe key. I am then taking the text in the textbox and taking away one character. this is ok but the cursor now is at the beggining of the textbox instead of at the end of the last character where it should be.

Is there a better way to do this?

User Entering Values Into A List View
What I need to have is some kind of control that will list a bunch of products and have the ability to have the "amount" of that product entered in beside it.

But because the list of products is dynamic, (based on a combobox selection), I can't just hard code them into the form. Also, the user will be entering in many volumes at once, so doing a drop down box for the products will just waste time.

I was wondering if it was possible to enter values into a second column of a list view. Is this possible?

I've seen some solutions using c# using the .editable property but I dont see that property anywhere for the listview I'm using....

Entering Only Numeric Values
How could I allow the user to be able to only enter numbers in a text field?

Entering Text Into Combo Box
Hi All

I havnt used combo boxes in dropdown combo style before, so need a bit of help with this

I am making a control panel for db values that my app uses
there are 3 cascading combo boxes in a control array controlled by a select statement.

this is how I populate each successive combo based on the last ones click event data. so showing the final data for a record that has all the selected properties
that means that currently if the user types in new properties it has no effect at all

if the user clicks a command button they should then be able to enter text into the combo box OR select a current value that they may change a successive combo (IE building up a new record)

what is the best way of pulling in this typed in text or selected vaue?

the click event wont fire if the user just types then moves focus and the click event wont suit for if the user selects an option that is already there

Ta in advance, much appreciated

Entering Dates In Combo Boxes (2) ??
Hello,

First of all thanks to "bsmith" for getting me started. I have now got the dates reading into the combo box, but after each date in the list appear two characters that look like two bold |'s, (ie) 01 Jan II etc...

Is there any way I can get rid of these, to be able to just show the dates (ie) 01 Jan
Below is the code I am using and also my original problem:

Hope someone can help...
Thanks,
Andy............

Code:
Private Function PopulateDates(strForYear As String)

Dim dtStartDate As Date
Dim dtCurrentDate As Date
Dim strForYear2

dtStartDate = CDate("01/01/" & strForYear)
dtCurrentDate = dtStartDate
Do While strForYear = Format(dtCurrentDate, "yyyy")
Combo1.AddItem strForYear2 & Format(dtCurrentDate, "dd mmm ") & vbCrLf
dtCurrentDate = dtCurrentDate + 1
Loop
End Function

Private Sub Command1_Click()

PopulateDates (2000)

End Sub

Original Problem...
Is there any possible way that you can use an array or something like it to fill a list box with all the possible dates of the year, with just the date and month and not the year????

(ie) having it automatically display 1st January til 31st December...without the year being shown...????

Hope someone can help...
Thanks,

Entering A Series Of Numeric Values (comma Seperated) Into A Text Box
Hello,

I'm an old newb, I used VB6 years ago, but now I'm back to do some additional projects and I'm quite rusty.

I'm using the following:

one text box called txtval
a command button called cmdadd
and another textbox called txtmeasures

I enter a numeric value in txtval, click my command button cmdadd and add the entered value to txt measures.

This I can do on my own. However I want to be able to loop this procedure to enter more than one value, so that the values are seperated by commas.

I'm stuck, I know I'm missing one more piece to this code but cant figure it out, see my code below:

I think I need some sort of variable to hold the subsequent values I enter.


Code:

Dim x As Integer
Dim i As Integer

For x = 0 To i
txtmeasures = txtval & ", "
Next

txtval = ""




Any help would be much appreciated!

Restricting A User From Entering 2 Decimal Points In A Value
Hi,

In my application I have a text box which accepts data and processes it accordingly. This text box is used to accept only numbers and so I have validated the same using the Keypress Event. I have disables all alphabets and special characters. The only characters that can be entered into this text box is numbers 0 to 9 (vbKey 0 to vbKey 9) and Backspace vbKey 46. However decimal points are allowed. But the problem is that a user can enter more than one decimal point. for eg: 1.2.1 I want to restrict the user from doing that.

I have tried entering the following piece of code.

In the Keypress Event:

Case vbKey Decimal
Keyascii = 0

But this doesn't help. I want the user to enter a value with a maximum of one decimal point.

Anyway to do the same.

Thank You

How To Prevent Typing In Combo Box?
I have a bunch of combo boxes I need to prevent typing in. They're pulling the data from tables, and the contents are managed in another form to prevent people from entering a bunch of junk. I'd like to prevent the users from typing in the combo boxes, but I don't want to lock them, as the users need to be able to change the values. Any ideas?

Prevent Duplicates In Combo
Ok, I am loading data to a form from an AccessDB via ADODB. While I am only displaying the first record, I want to populate a couple of Combo boxs also.
Code:
rsTable.Open "SELECT * FROM Table ORDER BY ID", CN,adOpenForwardOnly, adLockReadOnly
txtID = rsTable!ID
txtText1 = rsTable!Text1
etc

Do While Not rsTable.EOF
cboFName = rsTable!FName
cboSurname = rsTable!Surname
etc
rsTable.MoveNext
Loop

However this is causing duplicate entries in my Combo boxes, if there is more than one "Ann" in the database. Will have have to open a separate DISTINCT recordset to populate the combo boxes, or can I just check if "Ann" is already in the Combo?

Thanks in advance

How Do I Prevent User From Saving The Xls?
Hi All,
I need some help with preventing the user from saving the xls file and was hoping someone out there could tell me what I'm doing wrong.
What I have is an excell file that contains a single spreadsheet (called Main) which acts as my application menu. The user makes selections and provides input via this "Main" sheet and my vba code processes the input and then displays the output in a second sheet that I create on the fly.

I would like to prevent the user from saving the workbook so when it is reopened, only the one sheet (Main) is there. BTW...I also want to surpress any messages that may normally be displayed as well.

I've added the 2 lines below in the following subroutines but they don't seem to work as I understood they were suppose to.

Sub Workbook_BeforeClose
Sub Workbook_BeforeSave
Sub Workbook_Open


Code:
Application.DisplayAlerts = False 'surpresses messages?
ThisWorkbook.Saved = True 'fools excel into thinking no save is needed?
Any ideas?
Thanks,
Pat

Prevent User From Closing App
Hi,

I want to prevent the user from closing my application, even if they use EndTask or EndProcess.

I wrote a program using VB, run it every 10 minutes and I want users not to disturb the task and not to abort it themselves.

I startup the program at every startup in a hidden way so that it is shown only in the taskmanager not in the tastbar so as to not to disturb them. The program has a timer in it which executes every 10 mins. Is there any way for it ? Please help me out.

Prevent User From Closing With [x]
Hi-
I need to, if and when certain conditions are met, not allow the user to close the program via the [x] in the upper right corner.

I'm logging some time with a start/stop (timecard style), and the program needs to stay active during this so the user can work work work, then hit stop. I have working code in my cmdExit button, but when I go to the Form_Unload(Cancel as Integer) sub, and insert the same code, it will display my MsgBox but won't exit the sub, and thus ends the program.

So how do I go about this?

Prevent User Pressing Alt+tab
Im trying to stop a user from pressing ALT+TAB

They are using this to gain an advantage a confuse a peice of monitoring software.

Is there a way to stop it even if focus is not in the applications window.

This code i tried with no success

Code:
 Private Declare Function SystemParametersInfo Lib "user32" _
   Alias "SystemParametersInfoA" (ByVal uAction As Long, _
   ByVal uParam As Long, lpvParam As Any, _
   ByVal fuWinIni As Long) As Long

   Private Const SPI_SCREENSAVERRUNNING = 97

   Private Sub Command1_Click()
     Dim ret As Integer
     Dim pOld As Boolean
     ret = SystemParametersInfo(SPI_SCREENSAVERRUNNING, True, pOld, 0)
   End Sub

   Private Sub Form_Load()
     Command1.Caption = "Disabled"
     Command2.Caption = "Enabled"
   End Sub

   Private Sub Command2_Click()
     Dim ret As Integer
     Dim pOld As Boolean
     ret = SystemParametersInfo(SPI_SCREENSAVERRUNNING, False, pOld, 0)
   End Sub

   Private Sub Form_Unload(Cancel As Integer)
   ' re-enable Ctrl+Alt+Del and Alt+Tab before the program terminates
     Command2_Click
   End Sub
 

this also blocks ctrl+alt+del which was an added advanatge

Thanks

How Can I Prevent Duplicate Entry In A Combo Box?
Hello All,
I was wondering if someone could tell me how to prevent duplicate entries in a combo box. I used to know how to do this, but it's been a couple years since I messed with vb6, so I forget.

For instance, I have a form with a combo box that the end user can use to add names to. My problem is that if the end user enters a name that is already there, it will put it in again. I want to prevent that and display a message saying that it is already there. Here is my code for the Command button to enter entry:
VB Code:
Private Sub Command1_Click()cboPlayers.AddItem cboPlayers.TextOpen "c:Documents and settingsDavedesktopcomboPlayers.txt" For Append As #1 'opens Players.txtOpen "c:documents and settingsdavedesktopcombo" & cboPlayers.Text & ".txt" For Output As #2 'opens or creates "the name of the player".txtPrint #1, cboPlayers.Text 'Writes the contents of the Combo box's text field to Players.text  Since previous line was Open For Append, it will add to the end of test.txtClose 'Closes all open filescboPlayers.Text = ""End Sub
Thanks You!

Prevent User From Erasing File
I have many users that are not savvy and use a particular Excel spreadsheet once a month. The file is saved on their desktop so they can find it easily.

Prevent User From Changing Author
hi~
i'm teaching my class excel and the students have to save their homework files to a network folder designated for them. i recently caught students taking copies of their homework files and transfering them via thumb drives to other students folders. the only reason i knew they did this was because i looked at the author property in file-properties and saw that the original author was not the user in whose folder it was in.
i have a feeling as soon as i confront the students about cheating they will be looking for how i found out and a way around this. you can easily change the author on a file and i was wondering if anyone knew of a way to prevent this. is there a registry entry that can be edited so that the author box is filled in automatically with the original user but can't be edited? any help would be very appreciated.

Prevent User From Typing In A Cell
I am trying to prevent a user from typing in a cell in Excel. I have tried to lock the sheet but this does not help as it still allows the user to enter edit mode in the cell. If I can't prevent the user from entering edit mode in a cell altogether then I need to know a way to end edit mode before the Excel window loses focus to another application. In normal manual use of Excel, ending edit mode can be done by simply having the user press the Escape key. This might work; however, I can't figure out how to trap the fact that Excel is losing focus or that the user is pressing keys in a cell. Could someone please help me as to the feasability of either preventing edit mode in Excel or ending edit mode upon each keypress or Excel loss of focus.

Any help would be greatly appreciated!!!

Context: Edit mode is preventing another application from continuing until the user switches back to Excel and ends Edit mode (if the user is in fact in the middle of editing a cell). This situation seems to be occurring because I have a module level variable in an Excel module which I am using (and need) to maintain a reference to this other application.

Prevent User From Moving Chart
I'm using MSchart in an application.
In the application I allow the user to select points on the chart. So I have to allow selections in the chart property window.

However if a user clicks on the chart, holds the button down, the user can drag the chart around inside the chart window.

And once the user has done that, he/she can now use the right mouse button and resize the chart itself.

I want to be able to allow the user to only select points on the chart. Nothing else.

Any help would be greatly appreciated.

Prevent User From Closing Word
I need to disable the X in the right upper corner of Word and the X of the active document in the menu bar.

Basically I want to prevent the user from closing the document until certain circumstances have been met (a certain number of sections for example).

The idear was by exchaning the normal menu bar with my own and putting my own close macro into it I would be able to prevent people from closing the document until their work is done (evil me).

But this wont work if people are able to use the X buttons.


If both X buttons can`t be disabled at the same time:

Is there a way to stop the document_close event?

Or to use the close event to open the document again immediately ?

Please don`t sent code with the userform_queryunload event or "removemenu API calls" which work for normal Userforms and MDIchilds, because these don't work - tried a bunch of these already.
