String compare?

[neji]

I've a weird problem and i think its because of a wrong typecast.

I wrote a dll with an IPCQueue. Then my dll passes a pchar with the path of the prozess in which the dll is injected to my Application.

From my Applications Callbackprocedure i pass the pchar value to another function

Code: Select all

  // temp is a global declared String Var
  temp := StrPas(pchar(messageBuf));

Now i get a Pathname from an inifile in this function and want to compare it which the temp var which i passed to this function
But it never says that they're equal. In the "watches" list of the debugger the two strings look equal at all

You can simply do "temp := pchar(messageBuf)". Don't know why the strings are equal and not equal at the same time. I'd say log the length of both strings (e.g. "Length(temp)") plus log the content of both strings. Obviously there must be a difference somewhere.

Not sure this makes sense but could it be escape characters (there are likely backslashes in the path) creates a problem somehow?

Sure. But it's not very probable that escape chars occur inside of a file path.
