• 0 : lpPath directory exists or was created.
• 1 : lpPath is invalid.
• 2 : can not create lpPath directory.

Integrating the CPathDialog into Your Project

1. Import two files "pathdialog.h" and "pathdialog.cpp" into your project.
2. Include the header file "pathdialog.h"
3. Declare an object for CPathDialog class
4. Invoke DoModal function to show dialog
5. If user press OK button, get path name user's entered by using GetPathName function.

Example of Using the CPathDialog Class:

#include "PathDialog.h"
void CTestPathDialogDlg::OnBrowserButton()
{
 CString strInitialPath;
 CString strYourCaption(_T("Your caption here..."));
 CString strYourTitle(_T("Your tilte here..."));

 m_ctrlPathName.GetWindowText(strInitialPath);

 CPathDialog dlg(strYourCaption, strYourTitle, strInitialPath);

 if (dlg.DoModal()==IDOK)
 {
  m_ctrlPathName.SetWindowText(dlg.GetPathName());
 }
}

void CTestPathDialogDlg::OnOKButton() 
{
 CString strPath;
 m_ctrlPathName.GetWindowText(strPath);

 if(CPathDialog::MakeSurePathExists(strPath)==0)
 {
  CDialog::OnOK();
 }
}
