I am working on a vb windows form application with several connected forms. Its used to manipulate a MySQL database. One of the sub-forms has the following code snippet:
[Code]...
Having created a database and testing it I get the following error message,
ARGUMENT EXCEPTION WAS UNHANDLED
Public Class Form1
Private Sub AddressBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddressBindingNavigatorSaveItem.Click
[code]....
My action during the test was to fill in a field, save it then changed the information within, only to get the above message.
Working with an If statement I have tried the following
If -0.6 > (LLum_Gline(8).X - LLum_Gline(12).X) > 0.6 Then
patient_frm.llum_gline = 2
MsgBox("Measurement is Abnormal")
End If
I am getting an error message that says Argument out of range exception unhandled. I have double checked and verified that LLum_Gline(8).X and LLum_Gline(12).X are in fact valid.Is my problem simply in how i am phrasing the If statement. Is there a way for me to phrase what im doing without writing multiple if statements?
Public Class Form1
Dim int As Integer = 0
Dim CustomerTable As New DataTable
Dim instance As New InvalidOperationException()

In the process of finnishing up the application. Some NOT all beta testers have had the same problem.
An error box that states: Unhandled exceptions has occurred in your application. If you click Continue, the application will ignor this error and attempt to continue. If you click Quit, the applicatiob will close immediatly.
An error occurred creating the form. See Exception.InnerException for detailes. The error is: Could not load file or assembly "Microsoft VisualBasic PowerPacks vs, Version = 9.0.0.0, Culture=neutral, PublicKeyToken=b03f50a3a' or one of its dependencies. The system cannot find the file specified.
The details displays this: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
This does not happen on all the forms within the app, just some. This happens on some systems running XP and the app runs fine on others running XP. So foar it has run on all systems running Vista. It happens some of the time on Windows 7
have anyone experience this error? I try to share my project to the other computer and i got this error:

I'm making a program from witch one could run an application with different credentials.I can compile the program successfully, but when I press the button to run the program I get the following error: Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.The system cannot find the specified file.The code behind the button is as follows:
Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process()
myProcess.StartInfo.FileName = "c:
un.bat /user:kreathyr c:getlogin.exe"
myProcess.Start()
Getlogin.exe does nothing but show the logged in username and run.bat utilizes the runas command.

I've added a handler for the "unhandled error" event in the applicationevents class but it never reaches that stage and there is no source code running that I can break into and diagnose.
The application was fine until I added a user control (nothing fancy, just a standard windows user control) and then dragged it onto a form in the app (user control and form were in the same application). The application builds and compiles without any errors or warnings but when I attempt to run it up I get the above error straight away.
Does anyone have any idea what it could be or even how I can go about investigating it? I'm a bit stumped on this one as I'm not sure how to investigate it. I removed the user control from the form and then I removed the user control from the application entirely but the error hasn't gone away. In all honesty the addition of the user control might be a red herring but the problem manifested straight after adding it.
An unhandled exception has occurred in your application??
View 3 RepliesI've been using it for three days, and tried to make my own application. Everything was going okay, it ran fine in the debugger and everything worked, so I assumed there would be no problems. But then when I went to run it from the exe in the folder, it shows me this:
Quote:
System.Threading.ThreadStateException: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.

[CODE]............
I copied what I think to be the most important part of it. I've been searching around, and it says to do something with the main method, but I have no idea what that means.
activating just In time (JIT) debugging-- I have a propmt that I have an unhandled exception in my application (??).
