strstr() works in debug but fails in executable

[cpoore]

A routine I used to see if the executable is running on the C drive of the PC on on a network drive as follows:

GetProjectDir (currentFolder);
 if (strstr (currectFolder, "c:\\")
 {

Sorry, not sure what key I hit...

Anyhow, a routine to check if the executable is running on the C drive or on a network drive:

GetProjectDir (currentFolder);
 if (strstr (currentFolder, "c:\\"))
 {
  // run local stuff
 }
 else
 {
  // run network stuff
 }

This works fine when running under debug mode, but always executes the "else" code after compiled.

Any ideas?

Hi, cpoore, have you considered using SplitPath function? It can return the drive only so that you can specifically test its value instead of searching for the occurrence of a string.

In case of physical local drive the function returns the drive name and the colon without the backslash, the same in case of a network drive mapped to a virtual drive in the computer. In case of a real network drive (e.g. \\RemoteComputer\\myprogram.exe) the function returns an empty string as the drive name.

Are you sure the drive letter is always lower case?

if (strstr(currentFolder, "c:\\") || strstr(currentFolder, "C:\\"))

might be better, or you could use the CVI FindPattern() function, which can do case-insensitive searching.

probably TAB followed by Space.  Happens all the time 😉

ooooooooo... The SplitPath function looks cool.  There's lots of places I could use that.  I can't believe I missed that one - I need to get out more. Thank you!

Would it be simpler to use the Utility Library function GetDrive()?

Perhaps something like this:

GetProjectDir (currentFolder);
SetDir (currentFolder); // to be sure
GetDrive (&driveNumber, &numberOfDrives);

Yes!  I did find that...

GetDrive (&driveNum, &numDrives);
 if (driveNum == 2)
 {
  // using local C drive
  }
 else
 {
  // using networked drive
  }

But the SplitPath function is still cool.
