Running a DOS program with parameters.

I got help from somebody here telling me how to run a DOS command using the
process variable. Problem for me is that I need to be able to pass
parameters to the program - multiple parameters at that. When I run the full
command line, which looks something like:

"C:\Program Files\ABC Amber Text2Image Converter\abct2img.exe"
"C:\LeftPanel.htm" "C:\LeftPanel.jpg" 0 5"

If I run the command from a command prompt it works fine. But if I run it
through the process command is get an exception with a "The system cannot
find the file specified" error.

Anybody have any ideas on what I can do?

Could I create a batch file and run that?

TIA - Jeffrey.
 
Hi Jeffrey,

You need to separate the executable and the parameters in two strings.

string exec = "C:\Program Files\ABC Amber Text2Image Converter\abct2img.exe";
string params = "C:\LeftPanel.htm C:\LeftPanel.jpg 0 5";

Process.Start(exec, params);

Click to expand...

Oops! You need to place a @ sign on the front of those strings
otherwise the slashes (\) will serve as an escape character:

string exec = @"C:\Program Files...."
string params = @"C:\LeftPanes.htm......"
 
I'm doing it in VB.Net so I don't need the @ signs. Or at least I don't
think I need it. I'll try it anyway.
 
Looks like I don't need to @ command (and I can't seem to find it anywhere
in the VB documentation.) but if I look at the variables they look fine -
they contain the values they are supposed to. I also tried replacing all of
the \ with \\ and it still doesn't seem to work.

I'll keep trying......

TIA.
 
My continuing saga......

Ah - the plot thickens.....I did exactly the same code in a VB.Net console
app and it worked fine. But I'm trying to do it via code behind in an
ASP.Net page. Looks like it's a security issue.

My ASPNET user is a member of Administrators so I don't see what that can
be. And it's already creating files in the directory so I know that's not an
issue.

Anybody got an idea of how to fix it?

TIA - Jeffrey.

I don't know if it makes any difference but I'm
 
Do you still get the same error with file not found? If so, the file is probably in another place.
 
Thanks everybody for your help. I finally got it working - only to have it
turn out that the program I'm calling (a third party program) doesn't play
nice so I'm taking a different tack.

Thanks again - Jeffrey.
