Hi Wayne,
I agree with Stoyan, you should give the full path to your application if
it isn't in the current directory of your program. CurrentDirectory is not
for that purpose, This feature is provided primarily for shells that need
to start an application and specify its initial drive and working directory.
I tested the API on my system using the following statement , and it works
fine.
Also it seems you are using This API .NET via PInvoke, I'm not sure if
there is something wrong in the delcarationg of your API and related
structures. Here is my definition, I hope it will be helpful to you.
If you still have problem on this issue, please follow up this issue in
windowsform group, I'll be glad to help you.
Thanks!

| Hi,
|
| Is "test.exe" in your executable's path. Here's (part of) the
documentation
| of the lpApplicationName parameter:
|
| "The string can specify the full path and file name of the module to
execute
| or it can specify a partial name. In the case of a partial name, the
| function uses the current drive and current directory to complete the
| specification. The function will not use the search path."
|
| Also, why don't you get the last error, or just throw "$ERR,hr" in the
watch
| window to see what's wrong?
|
