File and Directory Picker Control

Posted by Lee Hamel on March 4th, 2003

Environment: VC6

The classes that come with Visual Studio for picking files and directories work, but they aren't as clean and user friendly as they should be. My FilePickCtrl class is very similar to what Explorer uses for views, but with some slight differences. The following features are supported:

  • Display small or large icons for detected drives
  • Display small or large icons for files and directories
  • Add filemasks to limit display of files
  • Display only directories so the user can only choose a directory
  • Turn on/off the display of the current directory

To add the control to your program, add FilePickCtrl.cpp and FilePickCtrl.h to your project. Drag FilePickCtrlDemo.rc into Resource Editor, expand the Dialog tree, highlight IDD_FILEPICKCTRL_DIALOG, hold down the Ctrl key, drag the dialog into your program's dialog tree, and close the window for FilePickCtrlDemo.rc. Your project should now have a copy of IDD_FILEPICKCTRL_DIALOG in its Resource Editor.

    Hi,

    Nice article, I don't really understand people who say that it's useless. I wanted to design and develop my own CFileDialog and voil�, thanks to you :). However It still believe it's better to inherit from CFileDialog and to redesign it, hide buttons, resize...

    Thanks again,
    JM

    the shipped executable file works fine, but when I compile the source code and execute (without any modification), a double click in the files/folders list over an empty area generates a "debug assertion failed" error ...
    Does anyone have an idea on how to fix this ?
    Thanks

  • Memory leak (?) and small code change

    Posted by Legacy on 07/10/2002 12:00am

    I'm not sure, but I think where is a memory leak. Objects created with new are never deleted.


    I replaced


    void CFilePickCtrl::PopulateFilesCtrl()

    {

    	...

    	dirData.next = NULL;

    	...


    with:


    CLocalFileCtrl::CLocalFileCtrl()

    {

    	dirData.next = NULL;

    	fileData.next = NULL;

    }


    void CFilePickCtrl::PopulateFilesCtrl()

    {

    	...

    	// pDirData cleanup

    	pDirData = dirData.next;

    	while (pDirData != NULL)

    	{

    		pDirData2 = pDirData->next;

    		delete pDirData;

    		pDirData = pDirData2;

    	}

    	dirData.next = NULL;


    	// pFileData cleanup

    	pFileData = fileData.next;

    	while (pFileData != NULL)

    	{

    		pFileData2 = pFileData->next;

    		delete pFileData;

    		pFileData = pFileData2;

    	}

    	fileData.next = NULL;

    	...


    2. And small code change:


    if ((findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) && findData.cFileName[0] != '.')

    {

    	pDirData->next = new struct FILESCTRL_STRUCT;

    	...

    	m_numDirItems++;

    }


    while (1)

    {

    	if (!FindNextFile(h, &findData))

    		break;

    	if ((findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) && findData.cFileName[0] != '.')

    	{

    		pDirData->next = new struct FILESCTRL_STRUCT;

    		...

    		m_numDirItems++;

    	}

    }


    I replaced with:


    do

    {

    	if ((findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) && findData.cFileName[0] != '.')

    	{

    		pDirData->next = new struct FILESCTRL_STRUCT;

    		pDirData = pDirData->next;

    		...

    		m_numDirItems++;

    	}

    } while (FindNextFile(h, &findData));


    The same work with smaller source code.

    Since the original file open / save dialogs do not work in multithreaded COM environments, I could in just a few hours adapt the dialog to my needs without much thinking.

    To the ingnorants who posted other comments:
    Programming is not always just clicking a few dialogs together.

    In my opinion are the standard API Dialogs really shit ...
