VB.NET....sending command line arguments via process.start

Matt_Hirst · 8 May 2007 at 17:47

Hi,

I have written a program that opens a DOS program that sits waiting for a filename to be input, how do I pass the name of a file to the started process.

I asked the question elsewhere to be told that I could probaly do it by passing command line arguments to the started process - so how do I do this???

regards,

Matt

I have a visual way of selecting the file, common dialog, but the dos program requires the filename input inorder to process it.

Thanx for that...

The Dos program is a compiled fortran scientific program - with no manuals or anything.

Question if I include the arguments as you have shown does that act in a similar way to if I wrote a batch file as follows:

myprog.exe myfile.txt

Where myprog is the compiled fortran program and myfile.txt the text file requiring processing??

If this is how it works then, I have tried this and the fortran program doesn't accept arguments, it just loads and asks the user to input a filename.

It won't accept the command line arguements as typing the exe name then filename doesn't work it just starts the exe.

Is there any way of passing the filename then??

P.S. I have tried sendkeys all this does is pass a backslash to the dos program, no matter what you send.

Will give it another try tomorow...

I wasn't sure if sendkeys would only work with a prog designed to run under windows, obviously the prog I am running is designed to work only under Dos.

Have tried sendkeys again and all I get is the \ character displaying, if I send a filename where the file doesn't exist I get several \'s, which is weird.

I have received an email suggesting that in VB6 you could use API calls to o this, am new to VB so any help would e appreciated.

Anyone else got any better ideas?

regards,

Matt

Sendkeys in vb and vb.net just puts up a \ character.

It would be nice to rewrite the program in VB, but it is a scientific modelling program - hence complex.

I am thinking it may be a better idea to get a Fortran compiler, make a basic program and then see if I can link into this somehow?? :confused:
