GetOpenFileName

[Technocrat]

Why is it when OFN_EXPLORER & OFN_ALLOWMULTISELECT are on and I do a multiple select all I get is the path back and not the files?

char szFileName[MAX_PATH];
OPENFILENAME ofn;
ZeroMemory(&ofn, sizeof(ofn));
szFileName[0] = 0;

ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = NULL;
ofn.lpstrFilter = "All Files (*.*)\0*.*\0 Text Files (*.txt)\0*.txt\0\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT;
ofn.lpstrDefExt = "*.txt"

if(!GetOpenFileName(&ofn))
{
MessageBox(NULL,"Unable to locate File","Error 32",MB_OK | MB_ICONSTOP);
return;
}

MSDN:

OFN_ALLOWMULTISELECT
Specifies that the File Name list box allows multiple selections. If you also set the OFN_EXPLORER flag, the dialog box uses the Explorer-style user interface; otherwise, it uses the old-style user interface.
If the user selects more than one file, the lpstrFile buffer returns the path to the current directory followed by the filenames of the selected files. The nFileOffset member is the offset, in bytes or characters, to the first filename, and the nFileExtension member is not used. For Explorer-style dialog boxes, the directory and filename strings are NULL separated, with an extra NULL character after the last filename. This format enables the Explorer-style dialogs to return long filenames that include spaces. For old-style dialog boxes, the directory and filename strings are separated by spaces and the function uses short filenames for filenames with spaces. You can use the FindFirstFile function to convert between long and short filenames.

Normal string functions won't parse this correctly.

To parse that returned string:

#include <stdio.h>

int main(void) {
	const char *str = "hello\0world\0other\0string\0";

	const char *p = str;
	while(1) {
		if(*p && *(p + 1)) {
			printf("%s\n", p);
		}

		while(*p) ++p;
		++p;

		if(*p == 0) break;
	}

	return 0;
}
