I made a dialog box in the DLL, embeds a CMFCShellTreeCtrl, do nothing, then use this dialog as a modal dialog, but
According to the following:


This is a function of exe calls:

Void OpenDlgSelectDir (const char * prjName, char * re)
{
AFX_MANAGE_STATE (AfxGetStaticModuleState ());
DlgSelectDir DLG.
If (IDOK==DLG. DoModal ())
{
return;
}
}

This is the DLL's code:
#include
BOOL DlgSelectDir: : OnInitDialog ()
{
CDialog: : OnInitDialog ();
//TODO: add additional initialization here
Auto PWND=GetDlgItem (IDC_MFCSHELLTREE1);
PWND CMFCShellTreeCtrl * tree=(CMFCShellTreeCtrl *);
The tree - & gt; SelectPath (" ");
return TRUE;//return TRUE unless you set the focus to a control
//exception: OCX property page should return FALSE
}

Is really a ghost,,
Drew back manually by clicking on the "computer", then click on "the computer", can display properly!
Don't know where is wrong? Ask the great spirit guide!!!!!!

Directly with BrowseForFolder

 
BOOL CMFCDlgApp: : InitInstance () 
{
. 
InitShellManager (); 

. 
} 

Void CMFCDlgDlg: : OnBnclickedButton1 () 
{
If (afxShellManager) 
{
Cstrings sOut. 
AfxShellManager - & gt; BrowseForFolder (sOut, this); 

} 
}
