Passing Array Value In Textbox. The Textbox Turns Up Empty.
I am passing the value of an array to a textbox, but it always turns up empty. When i pass the same value to an excel cell, i get the value. The function calculates the value of USCityA

I am giving parts of the code below:
Redim Pline(9)
Pline(9) = USCityA
test = "Hello"
USA = test & Pline(9)

In another sub, i call this funtion above to allocate the value of USC to the city as shown below:

CityA = USA

Activesheet.OLEobjects("txtbCityA").Object.Value = "CityA:" & CityA


The value i get in my textbox is only "Hello". When i pass USA to an excel cell, i get "Hello Fortworth" (or whatever the value of "USA" is calculated in the function)

how can i reset or clear a textbox when i click on a command button??

Listbox Reset - Stumped
need a little assistance in reseting selected items in a listbox. Here's what I got: I have two listboxes list1 and list2. when an item is selected out of list two, i make sure that nothing is selected in list1 and vise-versa. So i coded as follows:

if list1.selcount>0 then
list2.selected(list1.listindex)=false
endif

same code placed in list2.

It works but it clears both listboxes for some reason resulting in having to click on the desired list box a second time.

Any help available for this issue?

Thanks as always.

Reset Password Char For Textbox
Hi,

I'm trying to use a textbox for two things - one requires the text to be hidden (i.e. password char = *) and the other requires the user to see the text.

I can easily set the text to be hidden using textbox.passwordchar = * but how can I please remove the 'protection' and resort to standard no password char property.

Thanks

Reset Caret To Beginning Of Textbox
Ok I need to reset the caret to the very top row, all the way to the left, as if the textbox(text2) just got focus. I insert text into text2 and when i press enter it calls command5_click which in turn resets text2.text="" , so that works fine clearing the text, but text2 still has focus and instead of returning to the first line, the caret stays on the second line.

Any ideas? im sure its simple but ahh i dont know.. I tried using text2.selstart and also tried changing the focus to text1 then back to text2 but that didnt work either.

Empty ListBox
I want to run a line of code only if a listbox is empty.

I have tried doing this

code:

If frmLinker.List1.ListIndex = 0 Then
frmLinker.Width = "5295"
Else
If List1.ListIndex = -1 Then MsgBox "You have not selected an item to edit."
List1.List(TheIndex) = Text1
TheArray(TheIndex + 1) = Text2
End If

end code:

This doesn't work because = 0 i'm assuming is saying the same thing as -1.

I want the form to widen only if the list box is empy.

Any suggestions?

I figured it out myself. Foolish error on my part. For anyone interested it should look like this:

code:

If frmLinker.List1.ListCount = 0 Then
frmLinker.Width = "5295"
Else
If List1.ListIndex = -1 Then MsgBox "You have not selected an item to edit."
List1.List(TheIndex) = Text1
TheArray(TheIndex + 1) = Text2
End If

end code:

Textbox = 0 Or Empty
I need to give a message in a msgbox if the value of the text box is 0 or empty but it doesnt work
this is what i have tried...

MsgBox "That is an unaaceptable...
ElseIf txttax.Text = 0 Then
MsgBox "Please enter the Tax ...
ElseIf txtgross.Text = 0 Then
MsgBox "Please enter the Gross...
End If


and ive tried using the Or & And operators like this


If txtsalary.Text = 0 Or ""Then
MsgBox "That is an unaaceptable...
ElseIf txttax.Text = 0 And "" Then
MsgBox "Please enter the Tax ...
ElseIf txtgross.Text = 0 And "" Then

Is Textbox Empty?
Hi,
I placed six text boxes on the form and I want to fill in only three of them
with a "TEXT" randomly...and then stop the timer..if the number of textboxes with a "text" =3
thanks



VB Code:
Private Sub Timer1_Timer() Dim count As LongRandomizecount= Int(Rnd * 6) + 1For x = 0 To 6Text1(count).Text = "text box.." & countNext xBeepcon = con + 1 End Sub

Empty TextBox Please
I have the following lines of code in my program.

Ď1
txtFields(0).Text = Val(txtFields(6).Text) - Val(txtFields(7).Text)
txtFields(1).Text = Val(txtFields(8).Text) - Val(txtFields(9).Text)
'2
txtFields(2).Text = Val(txtFields(10).Text) - Val(txtFields(11).Text)
txtFields(3).Text = Val(txtFields(12).Text) - Val(txtFields13).Text)
'3
txtFields(4).Text = Val(txtFields(14).Text) - Val(txtFields(15).Text)
txtFields(5).Text = Val(txtFields(16).Text) - Val(txtFields(17).Text)

My problem is that if Val(txtFields(6).Text) - Val(txtFields(7).Text) are empty, then it puts a 0 into txtFields(0).Text and I donít want to see a 0, I would like the text box to be show empty.

Does any of that make sense?

Thanks in advance

Empty Textbox
I want to ask one question, I hope someone can help me.

When I add a new record to database, I write this code:

rs.AddNew

rs![Name] = txtName
rs![Closedate] = txtClosedate.
rs![Cost] = txtCost
rs.update

rs.Close
db.Close

In Access database, [Name] is a text, [Closedate] is a date/time, [Cost] is a number. And all the Required = No in their field properties.

The problem is if the user only input the name, but the txtClosedate and txtCost is empty, because it's open, it isn't necessary to close and without cost right now. When you click the Save button, it causes a "Data Type conversion error".

I know Name I can check Allow Zero Length = yes, then whatever you enter nothing, it does't has error, but I don't know how to handle the date/time and number.

Welcome email to me or post on board

Thanks a lot!

Finding Empty TextBox
I am using this code below to find text boxes on a form that have no value. I will just pop up a message box or something when I find them.

The problem is that when I step through the code I can see that it is moving from the type of control line straight to end if and next, i.e. it is not picking up the textbox type and therefore it misses the IF line for the textbox. I am on Version 5.0 if that matters?

Whats wrong?


Dim ctl As Control
For Each ctl In Controls
If TypeOf ctl Is TextBox Then
If ctl.Text = "" Then
'Place code to do something
End If
End If
next ctl

Empty TextBox In Access 2002 Before Update
What is the best way to determine if there is date inside a textbox on a form in Access 2002.

I've done the following before:

1. create a variable.
2. assign the textbox to the variable.
3. if the textbox hasn't been clicked an error will occur and will show a display box saying "enter data into all required fields"

Another way I've done it is use a variable called blank and used TextBox_BeforeUpdate function to set the variable if there is data or not.

if (txtBox.text = "") then
blank = ""
else
blank = txtbox.txt
end if

My Question:

is there an easier way to do this? it would be nice to have a function like

if txtBox.isEmpty then ...

Not Allow Lstbox To Add Empty Data Textbox Format And Question
First issue:
My listbox adds an empty space in the list view when there is no
data entered in my text box. The plan is to check the textbox to see if it is empty, and if so a msgbox states you must enter a name. The code I have works to some degree. The msgbox appears, however the empty space of the textbox goes to the list box anyway. I know there is something I'm missing, can someone
instruct me on what code I need to prevent the data from going to the list box.

Second issue:
I would like the users to enter a specific format in a text box. For
example, a users name in the following format- Smith, John. I would like the comma to to be added at all times, no matter the name. Not sure if it is possible.

Thanks in advance for your help...

Invalid Use Of NULL Parameter Error, While Using Textbox And Checkbox Empty Conditions
Hello..

I am building up one application with VBA coding and MS access DB.

The front end is a form that has two text boxes and one check box. I am facing error of "Invalid use of NULL parameter"

The situation is like this,

if only one text box has entry then I need to run one query, if both the text boxes have entries then I need to run another query. Same with the check box, if check box is checked I need to run one thing and if it is unchecked I need to do another thing. So what I am doing is,

txtBox1, txtBox2 and chkBox are the names of text boxes and check box.

If IsNull(Me.txtBox1) = True Or Me.txtBox1 = "" Then
      statements........
Else If IsNull(Me.txtBox1) = False Or Me.txtBox1 <> "" Then
      statements........
End If

So if I leave txtBox empty and try to click the button it gives error, "Invalid use of NULL parameter"

Same with Check box...

If Me.chkBox.Value = False Or Me.chkBox = "" Then
      statements......
ElseIf Me.chkBox.Value = True Then
      statements......
End If

Here what happens that when in the beginning I open the form and do some query without checking the box, it does not recognize the condition. Then I just check the box and again uncheck it and then run the same query it recognizes it!!!!

At the end of the program I am doing..

Me.txtBox1 = ""
Me.txtBox2 = ""
Me.chkBox = "" so is this causing the problem??

Please help with this...Thanks..

Passing A Value From Listbox To Textbox When Listbox Has 2 Values :( ?
I have a listbox, that I want to pass a .text value from to a textbox.
Problem is, The listbox is holding two values (as passed by 2 fields from a recordset) like this...


Code:
For i = 0 To rstCust.RecordCount - 1

lstCust.AddItem rstCust.Fields(0).Value & " " & rstCust.Fields(1).Value
rstCust.MoveNext

Next
Which displays the list like this:

When I click on the listbox, I want the value I click on to go to a textbox called txtCustID, but I dont want to send both values to it.

I only want to send the rstCust.Fields(0).Value to the textbox (which would be 001, 002, 003 etc. but not the name).


Can anyone help me do this?

Sorting A Table In VBA To Delete Empty Rows And Shift Empty Columns
 Problem is:

1a. Have a table, it may vary with regards to RxC.
1b. The first column always contains a company name. The final column always contains a count (zero or a number > zero).
1c. Every other column either contains text or a zero.

2. I want to delete all the rows where the final column = zero
3. I then want to go through each column of each remaining row and where the cell is =0 delete the cell and 'shift cells left'

A table may help to show what i have:


CompanyNames Field1 Field2 etc.... FinalColumn
==================== ==== ==== ====
BusNameA, text1, 0, 0, text4 ... ... ... 2
BusNameB, 0,0,0,0 ... ... ... 0
            ... ... ...
BusNameE, 0, text2, 0, 0 ... ... ... 1


And I want the table to show


==========
BusNameA, text1, text4, 2
BusNameE, text2, 1

Gurus, kindly tell me how i may do this?

SQL - Select All Records From Table Where Field Is Empty / Not Empty ?
I have a problem here in that I dont know how to execute this SQL query as I am not sure of the correct syntax...

I am trying to select all records from a recordset (populated by a table), where a particular field is empty...


So I guessed...

db.Execute("SELECT * FROM CUSTOMER ORDERBY CustomerID WHERE CustTelephone = "" ")


but its not working...


Similiarly, I need a query that returns all records where a certain field is filled, I have no idea how to do this one...


Guessed at...

db.Execute("SELECT * FROM CUSTOMER ORDERBY CustomerID WHERE CustOrder = "'(value)'" ")

(where '(value)' would mean any value at all)

funny enough its not working either


Can anyone please help ?

Dealing With Empty Fields And Empty Search Critera
I'm creating a database where not all the fields will contain information. Specifically, I'm making a database of materials and their properties. Some properties don't apply to all materials or are difficult to find, so they are blank. For example, I've been unable to track down the electrical resisitivity of acrylic.

I've also set up a search dialog box and an SQL statement to search between user-entered values for all the different properties. I'd like the user to be able to search for all the properties at once (ex: search for a material with a yield strength between 20 and 30 AND a dielectric constant between 1 and 3 AND a density between 1.2 and 1.5, etc.) but still be able to search for the materials when the user enters no value in to the search dialog box. With what I've done so far, the user must enter critera for all fields for the query to return any records.

I tried the following code, but it isn't working. Sigh. Any ideas? (The error message is after the code.)

Code:
Private Sub btnSearch_Click()
Dim sqlMatlSearch As String
    sqlMatlSearch = "SELECT * FROM [tblMatlProps] WHERE"
    
    If (Not IsNull(Me.DensityLower)) And (Not IsNull(Me.DensityUpper)) Then
        sqlMatlSearch = sqlMatlSearch & "(Density Between " & Me.DensityLower & " AND " & Me.DensityUpper & ") AND "
    Else
        sqlMatlSearch = sqlMatlSearch & " Density > 0 "
    End If
    
    If (Not IsNull(Me.GlassTransitionTemperatureLower)) And (Not IsNull(Me.GlassTransitionTemperatureUpper)) Then
        sqlMatlSearch = sqlMatlSearch & "(GlassTransitionTemperature Between " & Me.GlassTransitionTemperatureLower & " AND " & Me.GlassTransitionTemperatureUpper & ") AND "
    Else
        sqlMatlSearch = sqlMatlSearch & " GlassTransitionTemperature > 0 "
    End If

    DoCmd.RunSQL (sqlMatlSearch)


This code produces this error: Run-time error 3075: Syntax error (missing operator) in query expression 'Density > 0 Glass Transition Temperature >0'.

So the system want to update my data, but the data doesn't exists.

Does somebody know how I can prevent getting an empty line with an empty recordset ?

ListView To ListBox
Hi.

I have a listview (listview1) with 5 columns and a listbox (listbox1) on my form. Is there a simple way to add an item from the listview to the listbox when the user doubleclicks on it? It is full row selected, and I need to add column 3 data to the listbox when the row is double clicked.

Can I just do listbox1.additem <something> to populate the listbox?

Anyhelp would be appreciated.
