running DOS commands in a windows app

[hitechoutlaw]

i have this program call UHARC, maybe ya'll have heard of it?, newayz it's a compression tool (very good one at that) and its DOS only. i want to be able to run DOS commands from my program.

 

i want to make a GUI for it and befor i start, i need to know if u can run DOS commands with VB and if so, how?

 

thanks

Look into...

[msdn]System.Diagnostics.Process[/msdn].Start()

i can make the program start but to make archives and extract them u have to do DOS commands.

 

i.e.: one way to make an archive called files.uha and inslude all files in the directory:

 

uharc a -ed+ -d2 -mx -mm+ -r+ files.uha *.*

You could just automate the command line, for example you display a file list, the user chooses the files they want and click compress, you then use the command line of the utility to compress the specified files

thats exactly what i want to do...but how do i get it to run the command though the vb code?

quwiltw already showed you the Process class - was there something specific that that class doesn't have?

[hitechoutlaw]

if u just use the process class and start it with out the parameters it does nothing but start, say "nothing to do", and ends. if u can add parameters to the Process.Start, then will u tell me how?

One of the overloads of it accepts command line parameters.

Or you can use:

Dim proc As New System.Diagnostics.ProcessStartInfo("filename")

And then you can set process properties,arguments and all that.

And then you just do this:

System.Diagnostics.Process.Start(proc)

Or you can also use the overload which takes two arguments, the exe to run and the arguments to pass:

 

System.Diagnostics.Process.Start("notepad.exe", "myfile.ext");

ok i sat here and thought about it and ur right it does work. now i have another question:

i have "uharc.exe" hardcoded into the program, how, if its possible, do i get it to use that one and not the one out of the program?
