I've been trying to connect my application through ST-LINK according to the

I accidentally sent the incomplete question and can't find a way to edit it.

I wanted to ask, what is the policy of searching for the .cnf files in the file60.dll -- are the paths hard coded, or are they relative to the dll files, or can their path be set somehow?

I enclose the complete source code of my attempts below:

I managed to solve the problem by invoking the 'CSetWorkingDir' function. Sorry for the noise.
