I am new to vb.net 2015 but I am using vb6 for more than few years.
I am crating new form with three buttons and placed Toggle brakepoint at button1_click1(..) 1st line of code. On clicking button in debug mode, execution stopping at 1st line and on pressing F11 key cursor moving with yellow highlight to next line and so on.... But I am watching form nothing is getting changed in executed form unless I execute command refresh after every line (just to watch form changes) or completion of whole sub that is on moving out of end sub form getting refreshed.
But in vb6 on moving out of every line form was getting changed.
Can anyone please help me out how to get form automatically get refreshed on moving out from every line of code. Thanks
1) Before Refresh() code 2) After Refresh() Code 3) VB6 not like vb.net
While I know that does not resolve your problem... It is working as designed. Please look at the following link, it may give you some ideas
Blank Form When Debugging

I can run a macro under forms, but when I look at the code behind the form, I am not able to step through it all.
I hit the line
Dat = [Forms]![frmMenu]![dtmDate]
and get the error:
Is there a way to resolve this so I can continue to test each step of the macro?
I opened the code with ALT + F11.
I am trying to pinpoint the queries which cause the macro to take so long to run.
You can't hit f5 to run + debug code in a form. You can do this for a standard code module, but not for what we call a class module.
If you wish to debug/step code in a form? Launch the form (normal view). Then go to the code behind, say a button click, and now you can set a break-point.
So, single step, or debug of forms code requires you FIRST load the form as normal. (you can't thus use f5 to run such code). But, you CAN debug as per above.
is there some way to repair broken functionality in ms access, like recompiling the thing?
I have a button on a form that is supposed to run vba code when clicked. The button no longer works, after like a couple of months. Except for the button getting focus nothing happens. I have tried the compact and repair option in access with no luck. The code works fine btw. I have made a new random button somewhere else on the form and literally copy pasted the vba code from the on_click event of the broken button to the new one, and on the new button it works perfectly. No problems at all. The old one, however, nothing. No matter what I do. I deleted the vba code in the on_click event, saved, closed and opened access again, then reentered the code. Still nothing. I tried removing certain functionality from the button by removing line by line, trying to see if any one line is the issue. Nothing again, no errors are being displayed, I don't think the button even runs the vba code at all.
In case someone wants to look at the code:
Private Sub Befehl107_Click()
[NavigationSubform].Form![stoffe_abfrage subform].Form.FilterOn = False
[NavigationSubform].Form![stoffe_abfrage subform].Form.Requery
Me.FilterAlleLink = "Alle"
Me.FocusDummy.SetFocus
End Sub
The button basically turns off the filter on a subform, requeries the form, sets the value for a textbox on the local form, and then gives focus to another textfield. Nothing complex really. I have 3 more buttons of the same type on my form that manage different filters for the same subform with almost identical code, they all work fine. Just this one broke.
Again, the code works fine if I make a new button, but on the old one it does not do anything.
Obviously I can just replace the button, but that would be annoying if down the line there is other functionality referencing it etc. So I was wondering if anybody encountered a similar problem and has a solution. Given that I have only worked with access for like 2 months total and already have this issue I hope there is some way to repair this more quickly, since I am now assuming that this will happen more frequently. Not sure though, maybe someone with more experience knows if this is common.
Edit: I just checked if literally copy pasting the broken button itself works and yes. I copy paste the broken button somewhere else, then copy paste the vba code from the broken button to the copy, and the copy now works...
I am using vb.net 2008, I added a button from design view in one of my forms.It shows in the form design view, I gave it the click code to load another form but after I run the program and look in that form, it does not show the button that I added while I run the program. what is the problem? And What are the solutions?
Thanks!
As you can see, I added a Back Button here
THis image is while I run the program. Back button is not displayed here.
I would suggest running something like this in order to see if the control is there. Listing if it is Visible would also be helpful.
https://stackoverflow.com/a/12985464/7340880
Private Sub GetControls()
For Each GroupBoxCntrol As Control In Me.Controls
If TypeOf GroupBoxCntrol Is GroupBox Then
For Each cntrl As Control In GroupBoxCntrol.Controls
'do somethin here
Next
End If
Next
End Sub
The only way I can help you without you providing us more information like code or error info if exist (or maybe a warning), I will suggest you to copy the code from your button then delete the current button and a new one. Then paste the code back to new button.
And make sure you don't hide or change the visible property button somewhere in the code. If you are working with positioning in the code make sure you don't move your button.
Thank you for your support. The problem was that it was running the old .exe file. I deleted the old .exe file from the /bin/debug directory. And after I ran the program, it created me a new .exe file and hence my problem was solved.
Thank you again.
I already turned off auto-syntax check but this problem still persists. Whenever I try to modify a time, let's say from 08:30:00 AM to 08:30:05 AM, Access sometimes fills in a zero after I backspace to clear the 0. It forces me to have to quickly change the value otherwise it gives me an annoying pop up message saying syntax error....but the editor caused the error, not me!
How do I fix this? Please help me fix this.
This happens when code is running, which forces Access to constantly compile the VBA source code.
Typical example: a form is open that uses the OnTimer Event (has TimerInterval > 0).
To prevent this: Close all forms while editing code (Design view is ok).
If it's not forms, press the "Stop" button in the VBA toolbar (the blue square) to stop all running code.
I'm using vb.net 2013, and I have configured Shutdown mode to "When last form is closed".
On my main form, I have a menu item which has this code to close the application:
Application.Exit
Everything is working fine, except one case:
When I open a specific form, where a Combobox is created on runtime and I've used Addhandler to subscribe to several events.
The combobox is created when pressing a button.
When I open this form and I don't create the combobox, everything is working ok. If the combobox is created, when I close this form and try to close the application using the menu item, nothing happens. The application is not closed and no error message is displayed. (the same situation occurs when I try to close the main form with "x" button)
On the form's (where I have the combobox) close event , I tried to put a line of code:
MyCombobox.dispose()
But the situation is the same.
What can I do? Thank you!
What I do from my little experience is
1.) remove the MyCombobox from its parent control (I'm think this is in your combobox close event).
2.) set the MyCombobox to Nothing
3.) Dispose() it.
MyCombobox = Nothing
MyCombobox.Dispose()
It would be useful to see some part of your code for the close event so we can help you check. More power to you!
Update based on OP's comment:
I have read the following from MSDN: https://msdn.microsoft.com/en-us/library/system.windows.forms.form.closing(v=vs.110).aspx
From this, it is important to note that:
The Form.Closed and Form.Closing events are not raised when the Application.Exit method is called to exit your application. If you have validation code in either of these events that must be executed, you should call the Form.Close method for each open form individually before calling the Exit method.
