The '-t' is VFP command-line switch. See How to pass parameters to VFP EXE FAQ #17861 for more details.

>I read the posts and followed the tips, but there is something not working. I'm calling an executable from a dos prompt, and trying to pass a few params. The DOS prompt command is:
>
>x:\test\test.exe -t
>x:\test\test.exe "-t"
>x:\test\"test.exe" "-t"
>
>(I tried all three)
>
>The code in the exe's startup looks like
>
>LPARAM tcString
>?tcString
>
>That last command always prints ".F.", so the params I pass are never making it to the exe. I'm not sure what I'm doing wrong...I've followed all the posts/tips I found.
