GetOpenFileName doesn't start the open dialog

[Nobody/Anonymous]

Here is the code i use:

OPENFILENAME ofn;       // common dialog box structure
char szFile[260];       // buffer for file name
HWND hwnd;              // owner window
HANDLE hf;              // file handle

// Initialize OPENFILENAME
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = hwnd;
ofn.lpstrFile = szFile;
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";
ofn.nFilterIndex = 1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;
ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;

// Display the Open dialog box.

if (GetOpenFileName(&ofn))
    hf = CreateFile(ofn.lpstrFile, GENERIC_READ,
        0, (LPSECURITY_ATTRIBUTES) NULL,
        OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
        (HANDLE) NULL);

I have tried using OPENFILENAME_SIZE_VERSION_400 but it is not defined, how can i fix this problem?

The file dialogs are a bit sensitive to the contents of the OPENFILENAME structure.  (Note that when you declare a structure its contents are undefined.)

It is best to set the OPENFILENAME structure to all ZEROES to ensure NULLS in all the unused fields.

Put this line immediately after "// Initialize OPENFILENAME" line in your code:

memset(&ofn, 0, sizeof(OPENFILENAME));

This should solve your problem and I recommend you do this with all file dialogs.

szFile must contain empty string.
strcpy(szFile,"") or szFile[0]=0
