API::Browse Dialog Box

I Was wondering if someone could point me in the right direction:

I am looking for a common dialog box that allows the user to browse and select the directory that the user desires. I am looking for the directory and not a filename, so GetOpenFileName() would not be the correct API.
I tried searching msdn to no avail because the toc didn't feel like cooperating.

Thanks in advance,

How about SHBrowseForFolder()?

This is old code and comes with no warranty.

Code:

LONG WINAPI BrowseCallbackProc(HWND hwnd,UINT uMsg, LPARAM lParam, LPARAM lpData) {

CHAR tempStr[MAX_PATH];

// If the BFFM_INITIALIZEDemp message is received
// set the path to the current setting
switch (uMsg) {
	case BFFM_INITIALIZED:
		GetDlgItemText( (HWND) lpData,CNTRL_FOLDER,tempStr,MAX_PATH);
		// Send a message to the dialog box telling it to select this path.
		SendMessage(hwnd, BFFM_SETSELECTIONA, TRUE, (LPARAM) tempStr);
}

return 0; // the function should always return 0

}


void BrowseForFolder(HWND hwnd) {

BROWSEINFO bi;  // structure passed to the function
LPITEMIDLIST pidl;  // PIDL to the user's selection
CHAR tempStr[MAX_PATH]; // string used to temporarily hold the physical path
LONG retval; // return value

// Initialize the structure to be passed to the function.
ZeroMemory(&bi, sizeof(bi) );
bi.hwndOwner = hwnd;
bi.pszDisplayName = tempStr;
bi.lpszTitle = "Please choose a folder.";  // Message displayed to the user
bi.ulFlags = BIF_RETURNONLYFSDIRS  | BIF_NEWDIALOGSTYLE;
bi.lpfn = BrowseCallbackProc;
bi.lParam = (LONG) hwnd;

pidl = SHBrowseForFolder(&bi);

if (pidl != 0) {
	//get folder location
	retval = SHGetPathFromIDList(pidl, tempStr);
	//Free the pidl
	CoTaskMemFree(pidl);

	if (retval == TRUE) {
		SetDlgItemText(hwnd,CNTRL_FOLDER,tempStr);
		return;
	}
}

return;
}

Thx for the reply. I managed to get my prog working using the source code as a guide.

Thx,

You also could use this:

Code:

/* Displays a dirlistbox */
int GetFolder(HWND hWnd, char *achBuf, char *achTitle){
	LPITEMIDLIST lpItemList=0;
	BROWSEINFO bi;
	LPMALLOC lpM;
	char chRet(0);

	memset(&bi, 0, sizeof(BROWSEINFO));

	if(!SHGetMalloc (&lpM)){
		bi.hwndOwner = hWnd;
		bi.pszDisplayName = achTitle;
		bi.pidlRoot = NULL;
		bi.lpszTitle = "Velg folder";
		bi.ulFlags=BIF_RETURNONLYFSDIRS;
		if((lpItemList = SHBrowseForFolder(&bi))){
			SHGetPathFromIDList(lpItemList,achBuf);
			chRet=1;
		}else
			chRet=0;
		lpM->Free(lpItemList);
		lpM->Release();
	}else
		chRet=0;
	return(chRet);
}
