During file copy, I'm giving the absolute file name. But the compiler says file not found always. Is it a problem in my system or any error in my program.

I am trying to convert one of my unix text files to a dos text file. I am using the following command:
Shell(string.format("unix2dos {0}", sFileCompletePath))
I've already added the unix2dos command in my environment path on the server.But when I execute the above mentioned command I get a FileNotFound exception even when the file is located on the disk.
I'm developing a very simple app that does nothing more than launch two other apps. I'm developing this under the .NET 2.0 framework for WinCE 5.0 in VS2005.No matter what I do, I keep getting file not found exceptions not handled, and the program crashes. (Yes I should probably have a try/catch block, but this isn't the issue.)
Here's some code
fullPath = Path.GetFullPath(drivePath)
Me.Label1.Font = New System.Drawing.Font("Tahoma", 6.0!, System.Drawing.FontStyle.Regular)
Me.Label1.Text = fullPath & strDrivePath
Now, the label change here is not important, I only do this to output the full path of the directory, and strDrivePath is "whatever.exe"
If Directory.Exists(fullPath) Then
If File.Exists(fullPath & strDrivePath) Then
Me.Label1.Text = "EXISTS!!!"
[code].....
The irritating thing is after getting and displaying the full path (I know it's there) I check with the first IF to prove to the program it's there. No problem.I then use the second IF to prove to the program that the executable is there, and change the label output on screen to prove to myself the code is executed. The label changes. The file is there.
Then when I run the program, File not found exception. It's driving me insane. I've tried in multiple OSes (Vista and CE 5.0), I've tried in directories with spaces and no spaces, I've tried using Process.Start() and setting up the file details through the info command.I've tried putting a path in there directly instead of using variables. I've tried wrapping the whole kit and kabodle in quotes like this Shell("" & fullPath & strDrivePath & "" ) and like this Shell("""" & fullPath & strDrivePath & """").I've searched high and low on forums around the globe, including multiple threads here and I just cannot get it to work.
I'm trying to catch a user defined permission exception - i.e. a user does something their level of system access won't allow, permission exception is thrown. My problem is, the exception is caught and then rethrown as a genertic System.Exception.Is there any way I can deduce the original exception type, without resorting to string comparisons, like if ex.ToString.Contains("Permission denied"

I set a background image to my project. When I run it, It comes with an error, file not found:
Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.. I do have the file, and I didnt move places. I still have it and also reloaded it in the resources.
After adding a UserControl to a form which access my database I get this warning:
Warning1The database file cannot be found. Check the path to the database.

C:UsersUserDocumentsVisual Studio 2010ProjectsProject1Project1Options.Designer.vb2160
Thing is I never had a database at that location, my database is and has always been in MyDocuments in the Project folder itself. There is nothing anywhere in my code referring to that database! When I double click it I get sent to this line in the Designers window:
Me.Controls.Add(Me.BoxControl1)
Even though I get this error I can still access my database, so basically it does absolutely nothing except drive me mad! So how do I fix this?

This happens on two systems; Windows XP SP2 or SP3 - .net framework 1.1 & 2.0 & all necessary patches etc installed. Just can't seem to get around it.

I am trying to run a fortran .exe in VB with the Shell() command. The fortran .exe, when ran, it asks you for a file name. It works perfectly on it's own, but when I try calling it through VB Shell(), it does not work.. (i.e. I cannot get VB to get the file name in it.)
Added info:I am using VB9 but I'm writing in compatibility to .NET. As for the Fortran .exe, when you call it, it opens a command window where it asks for a file name (which I got as a string in VB and I'm trying to pass it in), then you press Enter and it's done. Basically the .exe takes a text file and creates a new text file. We've also tried adding & mystring when calling the exe, but it gives a "file not found" error.
We have an VB.net application that is being moved from one box to another. It runs great on the old box. The new box is configured the same as the old one but is on newer hardware. When I run the application on the new server it complains that the adobe toolkit that we use can not be found.
View 2 RepliesIt is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

View 12 RepliesWhen my application loads in Visual Studio 2010 I see this warning. Everything runs ok in it as far as I'm aware but I'm completely ignorant in this area. Could that cause me a problem and is there a way to replace that component? There is also the other warning you see in the screenshot.

I did a search for the entire solution and it didn't turn up any Sysem.Linq anywhere. I looked at every Imports statement in my project and I don't have any Imports System.Linq anywhere unless it's somewhere where Visual Studio's quick find search doesn't see it.
