Browse Folder dialog, search folder and all sub folders using C/C++..

//Call Browse Folder Window, Search Entire Folder and all sub-folders for desired file(s).
//This function was written by Jered McFerron ( JHawkZZ ). It's a pretty handy thing to add to your
//windows application, and I decided to publish this because I've seen many requests and few replies.


//Some parts of the Browse Folder dialog code taken from http://www.mvps.org/vcfaq/sdk/20.htm.


#include <windows.h>
#include <shlobj.h>
#include <string.h>

//BROWSE FOLDER - Opens a browse folder dialog.
void	BrowseFolder( void )

	TCHAR path[MAX_PATH];
	BROWSEINFO bi = { 0 };
	bi.lpszTitle = ("All Folders Automatically Recursed.");
	LPITEMIDLIST pidl = SHBrowseForFolder ( &bi );
	
	if ( pidl != 0 )
	{
		// get the name of the folder and put it in path
		SHGetPathFromIDList ( pidl, path );

		//Set the current directory to path
		SetCurrentDirectory ( path );
	
		//Begin the search
		SearchFolder( path );


		// free memory used
