Cannot use relative path [in batch file]

For some reason I need to write some program which launches another executable in a subdirectory of the current folder. The use of a relative path is crucial for my purpose. Trying this on the command line works OK:

.\mysubfolder\myexe.exe

However, putting the above line into a batch fille and running the batch does NOT work! Doing similar things in a VB program doesn't work either, and in the VB generated exe I found the following error message:

Runtime error 53: file not found.

On other mechines to which I have access there is no such problems. Does anyone know what's happening on my machine? (The problemic machine and the other comparing machines are all running Winxp Pro with SP2) Thanks.

 

From error msg- have you tried entering path STARTING from Hard Drive letter?
Realize this isn't relative directory.
But you also don't know what directory windows is starting from.
So need some consitency somewhere for batch to find the program.

C:\______ \mysubfolder\myexe.exe

For troubleshooting.
Try getting the full path name of ?.exe on your computer.
Get it on other computers.
Find out what directory windows is openinig when executing batch. Just a cmd run n look at prompt will do.
AND that will vary depending on what program run last.

You're assuming windows will open batch in starting from mysubfolder

 

Thanks a lot. I think I got the reason for the problem. I used to use xplorer2 Lite as a replacement of windows explorer. In the options of xplorer2 lite, there is an option "do not lock the current folder ". If this option is unchecked, there is no such problem any more.
