Shell Command Throwing A File Not Found Exception?

Jul 16, 2009

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.

Check The Folder To Search For The File, And If It's Not There, Go To The Next Step Without Throwing An Exception?

Apr 24, 2010

I'm doing a uni assignment and my application has to go to a specific folder and locate a file for data.The folder has 300+ files in it with a specific format for the naming of the files ie. the program goes to the folder looking for one specific file that has been derived from a different function and user input in the form.The program works fine when the file that it is searching for is there, but I keep getting a FileNotFoundException whenever the file that it's looking for is not there.I don't want the application to throw an exception every time the file doesn't exist because the program needs to return back to the loop to see if the next file is there or not.And so the loop continues until it's found all data and loaded it all into an array.How can I do a check of the folder to search for the file, and if it's not there, go to the next step without throwing an exception?

Retrieve Application Path For Associated File Type From Registry For Use With Shell Command?

Jun 17, 2009

I'm using VB.NET in Visual Studio 2008 in a Vista 64-bit OS. I'm trying to find an easy way (there must be one) to quickly retrieve from the registry the application file name and path to use in a Shell command to open a particular file. Specifically, I want the user in my app to be able to click on a PDF file and have the app open that PDF file using the application associated with PDF file types - Acrobat Reader, for example. Anyone have any suggestions as to proper coding & syntax for the following sequence?:

(1) Get name of .exe file associated with .pdf file type (most likely from the HKey Root Classes hive)

(2) Get path for the .exe file

(3) Shell("[pathname]appname.exe filename.pdf")

I've spent a couple of hours looking through the forums and haven't found what I'm looking for.

.net - Re-throwing An Exception From An Exception Catch?

Feb 14, 2011

catch an exception and then throw another exception? Like so:

Try
' Do operation xxx
Catch ex As Exception
' Operation xxx failed, need to execute cleanup

[code]....

The reason for doing this is that while I catch my exception on a higher level logic (to make sure I can log it properly), I need to do some actions in the event of the exception that I can only do inside my class/function.

Asp.net - .Except<T> Is Throwing An Exception

Mar 21, 2010

I have the following code:

I thought at first that because during testing GetFormsByStatus() returns 0 results maybe that was causing problems, but it doesn't make sense that Except() wouldn't work if the provided list had 0 items.

Asp.net - .Except<T> Is Throwing An Exception?

Aug 23, 2009

I have the following code:

Public Shared Function GetAvailableManufacturers() As List(Of Manufacturer)
'first get all the live orders and extract their mfrs'
Dim sos As List(Of OrderForm) = GetFormsByStatus(StockStatus.Building)
Dim unavailableMfrs As New List(Of Manufacturer)

[code]....

My idea to get available manufacturers was to get a list of all the manufacturers in my open forms, then get a list of all manufacturers and exclude all the manufacturers in the first list, illustrated like so (pseudo):

List A: {1,2,3,4,5,6,7,8,9,10}
List B: {5,7,10}
Result: {1,2,3,4,6,8,9}

I have set up my Manufacturer class according to this article so that it can be compared, but I'm still getting this error:

Unable to cast object of type '<ExceptIterator>d__92'1[csCore.Manufacturer]' to type 'System.Collections.Generic.List'1[csCore.Manufacturer]'.

I thought at first that because during testing GetFormsByStatus() returns 0 results maybe that was causing problems, but it doesn't make sense that Except() wouldn't work if the provided list had 0 items.

File I/O And Registry :: File Not Found Exception

Jun 16, 2009

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.

Running CLR Profiler Throwing An Exception?

Nov 23, 2009

I have a problem with running CLR profiler. It throws an exception: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

[code]...

I started out with a console application but half way I switched to windows form in the application properties. Does that have something to do with it? I do this because I don't want to show the console. My application takes about 57 miliseconds to run. Maybe it's too fast for the clr profiler ?

ExecuteNonQuery Not Throwing Error When Command Is Wrong

Oct 7, 2010

I'm passing in a sql command such as "EXEC StoredProc 0" into a a function called ExecMyCommand where StoredProc is a stored procedure taking a parameter of 1 or 0.It works fine with the following code.I had tried to judge success by looking at NumRowsAffected but soon realized that the -1 could represent a successful run even if -1 was the return value.So then I changed the code and return mLastRunOutcome = False if there is an error.So for testing I changed the name of the SP to like StoredProc2 in the database and ran the same command "EXEC StoredProc 0" and to my amazement, no errors were thrown in the code below..Of course ran the same command in Query Analyzer and it barked that there was no SP by that name.How do I know when a command ran successfully or not in code here? and Why didn't the ExecuteNonQuery throw an error when the command was not right??[code]
