Is it DEFINATELY going into the 'Else'? You haven't got another Me.Close further down?

ABSOLUTELY DEFINATELY. I have stepped thru the code in debug mode several time to make sure.

Bizarre!
How about something like:
Dim bLogonResult As Boolean = Logon()
If bLogonResult Then
MessageBox.Show(bLogonResult)
ElseIf Not bLogonResult Then
PDM.Common.ClientData.RestartApplication = False
Me.Close()
End If

Hi,
look at the entire exception text including the stack traceback, use the line numbers it
mentions (assuming a debug build), investigate the Form's constructor code.
Are you using extra threads, doing some illegal cross-thread Control access?
If you can't find it, publish all that information as is.

Hi,
I have a datagridview and on a column I have combobox.
When I choose a element from combobox I want to find the index of this element.
thanks.

Use the SelectedIndex property of the combobox.

Have you checked the documentation[^]?

I am running a program that search .wav, .wmv, and .mp3 files on the computer and automatically stores them into a database table. The table name is tblFileReport. I have another table called tblExclude which includes files that are excluded. However, I do not want to insert the file into tblFileReport if the file exist in tblExclude. For example, if "ExcludeFileName" is equal to filename then I don't want this file to be added to tblFileReport. But, if the file is not in tblExclude then add the file to tblFileReport. Here is the code that I have so far:
For Each folder As String In paths<br />
Try<br />
For Each file As String In My.Computer.FileSystem.GetFiles(folder, FileIO.SearchOption.SearchAllSubDirectories, patterns)<br />
fileName = System.IO.Path.GetFileName(file).ToLower<br />
<br />
Insert(file, fileName, CType(IPAddress.AddressList.GetValue(0), Net.IPAddress).ToString, System.Net.Dns.GetHostName)<br />
'End If<br />
Next<br />
<br />
Catch ex As UnauthorizedAccessException<br />
<br />
End Try<br />
Next
The string filename is the name of the file, for example chimes.wav, and if this name is equal to "ExcludeFileName" which is the filename column in tblExclude then do not add to tblFileReoport. I am thinking maybe an If, Then statement needs to be included in this code sample.
Any ideas?

You could put an If..Else block around your call to Insert() that calls a method to check whether the current filename is present in tblExclude.

Noone is going to send you any code. You have to write it yourself. CodeProject exists to help people write their own code. It is NOT in the business of just handing over code for you to turn in as your own work.

I just want to make sure you know, the spam you get as a result of your post, is not from this site, or even people who use this site, but automated programs that search the web for people silly enough to post addresses like that.
And, what Dave said. If you want it, write it, or pay someone to write it. Ask us when you've tried to do it yourself and get stuck.

Check out the Running Total Fields in the field explorer while editing your Crystal Report.

Hi!
I know how to save an image into an Access DataBase in a binary format and retrieve it in a memorystream and display it in a picturebox, only problem is .Gif files.
I found the way to save(.Gif Files) into a Database, but when I try retrieving it, it gives an Error.
I need help very urgently.
any help will be extremely appreciated.

A GIF file is no different than any other image file. If the code works for one file format, it'll work for another, PROVIDED that the code is written properly.
What's the code you're using to store the image and retrieve the image look like?
|
|
|
|
|
If it is very very very urgent you maybe could read the error message, look at the stack
traceback, and use line numbers to locate the problem. We can't.

well,
Dim img As Object = dataset.Tables(0).Rows(0)(0)<br />
<br />
Dim imgObject() As Byte = CType(img, Byte())<br />
<br />
Using theMemStream As New IO.MemoryStream()<br />
<br />
theMemStream.Write(imgObject, 0, imgObject.Length)<br />
theMemStream.Position = 0<br />
<br />
PictureBox1.Image = Image.FromStream(theMemStream)<br />
End If<br />
End Using
this is the code that I used, but it gave me this error:
first Error:
"A generic error occurred in GDI+"
Error Code = "-2147467259"
Second Error: (on cont...)
"Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang."
Third Error: (on cont...)
"Attempting to call into managed code without transitioning out first. Do not attempt to run managed code inside low-level native extensibility points, such as the vectored exception handler, since doing so can cause corruption and data loss."

This code is barely passable for reading image data and reconstituting it. What does the code look like that wrote the image to the database? After all, what good is the code that reads it (even if good) if the code that wrote it didn't do it correctly?

Hi,
your error code is 0x80004005 (E_FAIL), its most likely cause is a bad image file.
Assuming the exact same code runs fine with other image file types, I suggest you
try another GIF file (preferably originating from a completely different source).

Hello guys,
I like your advice.
I am programming a windows service in vb.net 2003 and I'd like to have the windows service run a windows form that provide me status information concerning the tasks of the service. And to make it more nice, minimize the form to the system tray.
How I do this properly?
I have done the following:
<br />
Private test As Thread<br />
Public Shared fStatus As New FormStatus ' The windows form<br />
<br />
Protected Overrides Sub OnStart(ByVal args() As String)<br />
' Create the windows form thread<br />
test = New Thread(New ThreadStart(AddressOf Me.dotest))<br />
test.Start()<br />
<br />
' The real Service work<br />
Communication.StartCommunication()<br />
End Sub<br />
<br />
Private Sub dotest()<br />
fStatus.Show()<br />
End Sub<br />
With this code, the form disappears almost immediately. If I use ShowDialog() instead of Show(), the notify icon does not process the click events.
Can anyone give me a nice advice to solve this issue?
Thanks.
