I have completed and distibuted a VB.net (VS 2008) winforms application to numerous users.
One user reports the following error when opening the application:
"[Application] has encountered an error and needs to close. We are sorry for the inconvenience. If you were in the middle of something, the information you were working on might be lost."
I can't reproduce this.
I have built my first VB 2008 application and now I want to install it on other Windows 7 & Windows XP computers. I have tried various Install Programs but they all giving similar problems. Is all I have to do is copy the contents of the bin directory to the other computers? [Code] When I try to run my application I get the message "MyApp has encountered a problem and needs to close". Can you suggest what I am doing wrong?
View 3 RepliesI have a weird XP only error. When i distributed my application to XP user it said right after he clicked the .exe without the GUI of the form "Application has encountered a error and program needs to close".
View 12 RepliesI am looking to prompt the user to save data when they close a form window in a winforms application. I can't figure out how to trigger the prompt to the user, should they click the red box at the top right corner of the form.
My application currently has a boolean flag, that is set to True on textchanged event. So I will only need to check for the boolean value in whatever event is trigger by the red box.
How would i go about closing my openfiledialog in the event that there is an error[code]...

I am a fresh graduate and I am working now as a developer By the way, I am not the one who developed this tool, it's the previous programmer and they gave the project to me to update it however, when I try to run the application in my local computer I am getting this error:

I was having problems updating information in my SQL database using my vb.net application, but recently I found the solution. However now I have run into another problem which is shown in the code below:
Private Sub cmdupdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdupdate.Click
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
'#######
conn.ConnectionString = "server=" & frmLogin.txtserver.Text & ";" _
& "user id=" & frmLogin.txtusername.Text & ";" _
[Code] .....
The exception message is:
Fatal error encountered during command execution.
I don't know if this is simply a syntax error that can be fixed easily, or something to do with my database configuration.
I am doing a regular update table scan
Using connect1 As New MySqlConnection(ConnectLocalhost.serverString)
connect1.Open()
Dim cmd = New MySqlCommand("set net_write_timeout=99999; set net_read_timeout=99999", connect1) ' // Setting tiimeout on mysqlServer

All I want is for the program to just "continue" when this thing happen. But that seems to be impossible. So I guess I need a way to make sure this bug doesn't happen. It happens randomly eery 800 entries or so.
Looks to me the connection is forcibly closed by remote host. In that case, I simply want to go where things left on and restart again.
I have to build an application using it in order to communicate with some software. Basically, I need to be able to call this exe and have it run to perform some tasks, then close itself down.I have the tasks running on page load but since I don't want the application to actually open, I use a Me.Close() to close it once it's finished the tasks. So, the whole thing works great (the tasks are even performed) except the Me.Close() causes a message to come up saying the application "has stopped working." Is it because I'm trying to close it while it's loading itself?I am forced to perform these tasks in VB, so please don't just say I should not be using VB.NET for this.

1) for the same deployed code, I SOMETIMES get line number in the displayed StackTrace error message and sometimes do not, even when the error message includes source code that I have written rather than a referenced binary. The project is compiled with a DEBUG configuration.
2) The application strangely minimizes to the tray when the error occurs (I thin it is unlikely that anyone can diagnose this issue w/o my more code posted, but I'll mention it anyways)
3) When I try to intentionally raise an error by, for example, dividing by zero hoping to test by global error handler, I get a dialog error message from the interactive debugger rather than jumping into my global error handler (which i want to debug because there is more to it than I posted.) Do you have any idea how to triggerand force teh execution of the global event handler?
I get this error message when running an application developed in VB. It used to works fine but for some reason it was asking to update ODBC but after that it cannot read the dbf file any more. The error message is speicified driver could not be loaded due to system error 126 (Microsoft dBase Driver (*.dbf)).Even I installed this visualFoxProOledb.exe and also MDAC 2.8 it still doesn't work.

I've just finished installing VS2010 on my computer. I have a project I built in 2003 that I'm trying to open in 2010.

I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.

Is it something dealing with the permissions set with the database server or something? I am new at .NET programming and I have been spinning my wheels on this for the past couple of days and I am at a loss. From what I research, this error should only occur if I was creating a web program, but I am not. It is a windows application.
Presently working a tutorial in visual basic 2010. I have encountered the error " keyword is not valid as an identifier" I have read the definition of an identifier in the beginners section. Although I undertand the definition of an identifier I still am not sure of it when looking at a line of code. The tutorial gives an analogy but does not show examples of identifiers as they would actually apprear in a coding project.
View 3 RepliesI have used the below code but its not showing the msgbox. What is wrong with this code ?

If result = DialogResult.Yes Then
me.Close()

I always useMe.Cursor = Cursors.WaitCursorfor a time taking functions like hitting the DB.Now if any exception occurs, I'll display the error message as:Msgbox(ex.Message)So before displaying any message, I need to reset the cursor to default.Is there a simple way to do it at in one place instead of writing it in all catch blocks.
Is there a way to inherit MessageBox class and override the functions?Other wise I need to code it in all the catch blocks or handle all the exceptions at one place which I don't want to modify the whole application now.
It seems like whenever i click my close button the application will close but the debugger is still in active.How to exit this debugger? :)
View 2 RepliesI have two Close() functions in same class as below:
[Code]...
Whenever I enter text, even a single character, into a textbox in any Form in my application it causes the form and its parent to close. I've checked for the following so far:
Errant/mis-assigned event handlers that may be interpreting a keystroke as a Form cancel I am using keypreview in several windows but debugging shows this to not be a cause Happens in any form of the application Happens even with brand new text boxes dropped on the form Tried removing the WithEvents declaration from text box declarations (VB.NET)
sometimes, when I use Form.close() when debugging my program, although the form is closed, the application is still running. I noticed this behaviour when using the msgbox function.
