ShellExecuteEx issue

[SLider3]

Hi

I'm using ShellExecuteEx to run a dos program from my bcb aplication. In lpFile i put the path to the program, and in lpParameters the line with parameters.
well, the dos program sends some messages to the monitor and i want to save them to a file.
If I run the program in command pronpt it's easy to do that:
prog.exe -i something - o something_else 2> output.txt
( 2> because i know it sends the messages to stderr)

I tried do had the " 2> output.txt" to the lpParameters string but it's not working. :\
So, how can i save those messages to a file?

Nobody knows what i have to do?
I wasn't clear enought?

 

[SLider3]

Come on ...it has to be a way to redirect the stderr to a text file using ShellExecuteEx.

Please ... i need help on this one.

I must admit, I've never tried it. Have you thought about putting the whole "prog.exe -i something - o something_else 2> output.txt" in the executable line?

Well ...i'm executing the external program using ShellExecuteEx.
I put:

SHELLEXECUTEINFO sei;
memset(&sei, 0, sizeof(sei));
sei.cbSize = sizeof(SHELLEXECUTEINFO);
sei.fMask = SEE_MASK_NOCLOSEPROCESS + SEE_MASK_FLAG_NO_UI;
sei.hwnd = NULL;
sei.lpVerb = "Open";
sei.lpFile = "prog.exe";
sei.lpParameters = "-i something - o something_else"

and the program is executed.


Then i changed the lpParameters to:

sei.lpParameters = "-i something - o something_else 2> output.txt"

But it doesn't run.

I'm shooting in the dark but have you tried:

sei.lpFile = "prog.exe -i something - o something_else 2> output.txt"
sei.lpParameters = ""

No. That doesn't work.

It looks like it should work with the lpParameters. This is probably a stupid question but I can't see why it won't work, but have you tried this at the command prompt to see it it will work there?

[SLider3]

yeah, at the command prompt it works fine.

 

[SLider3]

So, nobody knows how to help me? Noone never needed to do such thing?

I haven't tried it. Have you tried CreateProcess? More complex but it might work.
