Hi all,
I want to run an external app from an assembly. Simple enough... Process ExtProcess = new Process();
ExtProcess.Star tInfo.FileName = myAppName;
ExtProcess.Star tInfo.Arguments = myArgs;
...etc...
My problem is that the command I am cfalling produces an "Are you
sure?" message that is not overridable with a switch (eg. /y)
Is there any way for the framework to wait for the "Are you sure?"
string, and then send a response (in this case, "y")?
TIA

Marc,
What you could do is wait until a time you know that the application
will put up the message box, and then use the SendInput (through the
P/Invoke layer) to simulate the mouse click. Of course, you will have to
determine some way to find out when that message box is shown, and then send
the input. All in all, it's very hokey, but there is little you can do
about it, it would seem.
Hope this helps.

I found a workaround (as always happens just after I post a question,
never before...)
In this case, I am calling cacls.exe to set ACL on a file / folder. Process ExtProcess = new Process();
ExtProcess.Star tInfo.FileName = "cmd";
ExtProcess.Star tInfo.Arguments = "/C echo Y| cacls /E /R user:F");
works a treat.
Thanks.
Marc.

Is your process a console (text-mode) application? If so, you could use
something called "standard input/output redirection".
That is, .NET gives you access to the streams for input and out of the
console process (what it reads in and what it writes out), using the
StandardInput and StandardOutput properties of the Process class. If you
look at the .NET SDK Documentation for the StandardOutput property, you can
also find a simple example.
The idea is that you read the standard output until you find the "Are you
sure?" string, and then write the letter "y" (probably along with the Enter
key) to the standard input stream of the process.
That should solve your problem. GUI applications are a totally different
thing.
Hope this helps.

Since it is a command line program, you can also redirect the standard
input and output and watch for the message and then send the response
back.

Hello!
My application has to use external native library writing to stdout and
stdin. My goal is to redirect output within running process (no chance to do
that in child process - Process class redirection is useless in that case)
and I would like to do it without reverting to C-run time library P/Invoke
calls.
Any ideas how to do that?

In VB6 we can attach to a running process in memory and transmit information
back and forth. This allows us to have several different applications all
accessing the
same program running in memory.
In VB.NET when we try this it fails. We use the objName.Start(Process
Handle) function. It will indicate that the connection was sucessful but
gets no response
from the running process.
