API::Browse Dialog Box

[bc17]

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.

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:

/* 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);
}
