What's a Problem?
It has probably happened that you need a dialog like
CFileDialog (MFC) that allows you to select some items together. I do not mean multi select file feature but multi select files and folders.
If you search MSDN and the internet for libraries which do that for you, maybe the best things you would find are
CFileDialog for selecting single or multiple files and
SHBrowseForFolder API for selecting a single folder.
So the problem is that you need a utility that makes it possible to select every browsable thing.
What Should We Do To Overcome the Problem?
If you want to have a single class using it you can select a file or a folder or some files or some folders or a mixture of them. I searched for such a utility but found nothing. So I decided to provide it and the best solution that I found was changing
CFileDialog to do what I need.
CSelectDialog is a class that is inherited from
CFileDialog and makes it possible for you to browse your computer or network and select a mixture of files and folders. For my convenience (as implementer) and user, I add a member of type
CStringArray to the class to keep selected items after dialog returns
Difference of CSelectDialog and CFileDialog
- Their user interface has some differences (You can see it in sample image in Vista.)
WndProc functions of
CFileDialog are overridden in
Using the Code
CSelectDialog is similar to
CFileDialog. Simply define a variable of type
DoModal it. After user clicks the OK button, you can access the full path of selected items via
m_lstSelectedItems member. A code snippet that does this work is shown below:
CSelectDialog ofd(TRUE, _T("*.*"), NULL,
OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT,
_T("All files and folders(*.*)|*.*||") );
if( ofd.DoModal() != IDOK )
for( int i=0; i<ofd.m_SelectedItemList.GetCount(); i++ )
m_lstSelectedItems.AddString( ofd.m_SelectedItemList[i] );
If you want to disable multi select, you should make a change in
If you want to hide a
combobox and its label below select dialog, you should uncomment 2 lines below in
For prevention of exception in XP SP3, you should comment all lines containing
Points of Interest
When I searched the Internet, nobody provided such a browse dialog with this feature.
