I'm using the libtiff version v3.5.6 (Beta) under MSVC++ 6.0. I get this following message while trying to open a tiff file with the instruction TIFF* tiff = TiffOpen(myFile,"r"):

        Undhandled exception in myAppli.exe (NTDLL.DLL): 0xC0000005: Access

Most of my tiff files work correctly with the instruction above, but others don't. All the files have the same attributs and the same compression algorithm.

    I'm now facing the same problem:
First-chance exception in data.exe (KERNEL32.DLL): 0xC0000005: Access Violation.
The program 'C:\My Documents\data\Debug\data.exe' has exited with code 0 (0x0).

The picture caused the problem was safely opened by photoshop, but the program crashes when it runs to the line TIFF* tiff =TiffOpen(myFile,"r").

Changing r to ru does not help.

The weirdest part is that when I wrote a three line test program just to open and close the tiff files, it works perfectly for every file I tried; then I added up some dialog boxes, bottons and list boxes, access violation happened......only to some of the files. When it comes to my nearly-finished program with all interface it needs, access violation happens all the time.

Can anyone help?
