VS 2010 Run Code When Leaving Text Box
Sep 12, 2011
I'm trying to update an old code that I don't have the source code for. In this code, the user enters an integer in a textbox as part of a form. Once they move to the next textbox a new form opens to input the number of files that the user chose (in the textbox).I have created all of the forms, but I can't figure out how to get the code to open the new form once the integer has been entered in the textbox and the cursor has moved to the next textbox. I would prefer this to happen automatically and not involve a button.

When a user leaves a TextBox on the form I execute a format and save to a variable. This is saved to a database by clicking on a ToolStrip button.
The problem occurs if the user moves the mouse directly from the TextBox to the Button. Neither the Leave event or the Lost Focus event is triggered, the variable is not created and, of course not saved.
If I put the code in the Save Button and the User moves to another control, the formatting(data type Double to currency format in the TextBox) that I want to show is not executed.

I'm trying to find where this code might be leaving old connections open, and I found this code that might be the cullprit. It is in a function. I'm wondering if this connection would close, if an exception occured from within the USING statement?

The simple line:
Enabled = False
Leaves the user no options to do anything with the program.What I want is to disable everything using the given line (or if anything else), but leave a Menustrip enabled.

I'm looking for a way to process the text entered into a textbox, before the the focus is lost from the control. Or a way to pass a reference to the control to a function/sub when the control has lost focus. In Access I would be able to use the AfterUpdate event. I have tried the following events, but have not figured out how to get what I want from either of these events:
- TextChanged (tried to capture the Tab key, didn't work)
- Validating (when fired for Text1, the ActiveControl name is Text2 which is the next TextBox control)

I'm trying to use StreamWriter to write to a text file; it creates the file fine, but when I open it up, it's still empty. I marked the code below where the writing action takes place.
vb Public Sub BHorse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BHorse.Click
Dim oMarketsReq As New BFExchange.GetAllMarketsReq
Dim oMarketsResp As BFExchange.GetAllMarketsResp
Dim BFWrite As System.IO.StreamWriter
BFWrite = IO.File.CreateText("C:Datamarket.txt")
With oMarketsReq

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one! Am I doing something wrong?[code]

I am coding a simple calculator and I need the textbox to show the previous entries when I enter them. I hear the best way to do this is by Append Text? For example I click 3 Then + The textbox will show "3+" etcetera.

I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?

I have a modal pop up that is supposed to upload documents. It does that just fine, except that it doesn't give them a title, therefore nothing shows up on my page since Title is how they show up in the list. What should I replace LinkTitle.Text with to get this to work?I am trying to fix this guys code because none of it worked right. I added a comment below that has new code in it that is parameterized. This is in ASP.net 4.0 VB using Microsoft SQL Server.[code]

I find that if I do me.close and then reopen the form with showDialog later, things are as they were before I closed it. If I use me.dispose and then later open the form again, its as if it was never opened before. Are these two both valid methods for leaving a form?

I am experiencing a strange issue with a VB6 -> VB.Net conversion. There is a function that uses ADOX to look through the tables in a given database, and reset the seed values of any columns in said tables with the auto increment property set to true.I tracked the issue down to a call of "col.Properties("Autoincrement").Value". If this line of code is commented out, then the file handle properly terminates when I close both the ADO and the ADOX connections at the end of the function. If I leave that line in, the handle stays open despite the closing calls and forcing garbage collection.Here's how I am closing the objects:
System.Runtime.InteropServices.Marshal.ReleaseComObject(adoConn)
Dim connection As ADODB.Connection = cat.ActiveConnection
If Not connection Is Nothing Then

I'm refactoring the code getting ready for some major work. I want to remove the if/endif pair but leave the contents (do lots of stuff) intact and in place.
In Visual Studio 2008, what is the easiest way to do that without making a mess

I have a DGV with a CB column in VS2008. I would like an event when a DGVCB selection is made (without leaving the cell). It will probably have to be a DGV cell or row event but I can't find one that fires as soon as a DGVCB selection is made.

Our program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.

Need help removing a copy of my program shown on the Task Manager after I close.
I must kill a conflicting program that cannot share the COM port and then reinstate when myprogram ends. To reinstate I use: System.Diagnostics.Process.Start(conflictingPath & conflictingProgram)
In the last line of my Form1.Closed I try to end all with:System.Windows.Forms.Application.Exit()
Not working - each time I run this program it does kill the conflicting program, can do its dialing function and upon closing reinstates the conflicting program. But each time another copy shows under Task Manager.

Wondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.
