Win32 Open/Save Dialog Box

[lhayes00]

Hi,

I have used the MFC classes for the windows common dialog boxes numerous times. For a college project I am using a standard Win32 application without the use of MFC. How can I display the file selection dialog box (CFileDialog in open mode) and then retrieve the selected file and path into a char[] array?

Any help would be greatly appreciated!

BOOL SelectFileName(LPCTSTR lpctstrInitFileName, LPTSTR lptstrSelectedFileName, DWORD dwCapacity)
{
BOOL bOut = ((lptstrSelectedFileName != NULL) && (dwCapacity > 0));
if (bOut)
{
ZeroMemory(lptstrSelectedFileName, dwCapacity * sizeof(TCHAR));
}

OPENFILENAME ofn;

TCHAR strFileName[MAX_PATH];
TCHAR strFileTitle[MAX_PATH];
TCHAR strInitialDir[MAX_PATH];

ZeroMemory(&ofn, sizeof(OPENFILENAME));
ZeroMemory(strFileName, MAX_PATH * sizeof(TCHAR));
ZeroMemory(strFileTitle, MAX_PATH * sizeof(TCHAR));
ZeroMemory(strInitialDir, MAX_PATH * sizeof(TCHAR));

::GetModuleFileName(::GetModuleHandle(NULL), strInitialDir, MAX_PATH);

if (lpctstrInitFileName != NULL)
{
_tcsncat(strFileName, lpctstrInitFileName, MAX_PATH);
}

ofn.lStructSize = sizeof(ofn);
ofn.lpstrFile = strFileName;
ofn.nMaxFile = MAX_PATH;
ofn.lpstrDefExt = ".txt";
ofn.lpstrFileTitle = strFileTitle;
ofn.nMaxFileTitle = MAX_PATH;
ofn.Flags |= OFN_OVERWRITEPROMPT | OFN_EXPLORER | OFN_ENABLEHOOK | OFN_ENABLESIZING;
ofn.lpstrFilter = "Report\0*.rep\0All Files (*.*)\0*.*\0";
ofn.hInstance = ::GetModuleHandle(NULL);
ofn.hwndOwner = GetAppMainWindow();
ofn.lpstrInitialDir = strInitialDir;

BOOL bRet = ::GetSaveFileName(&ofn);

if ((bRet)&&(bOut))
{
_tcsncat(lptstrSelectedFileName, strFileName,
MAX_PATH > dwCapacity - 1 ? dwCapacity - 1 : MAX_PATH);
}

return (bRet);
}

Sorry, that's for file saving.

The function I would use is... GetOpenFileName()...

To Quote MSDN...

The GetOpenFileName function creates an Open dialog box that lets the user specify the drive, directory, and the name of a file or set of files to open.

As for placing the filename in a char array...

The GetOpenFileName() function takes 1 parameter, an 'OPENFILENAME' structure. That structure has a member 'LPTSTR lpstrFile' which you would set to your array. Then you would call GetOpenFileName()...

Some sample code below...

OPENFILENAME ofn={0};
char array[MAX_PATH]={0};

ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = hWnd; // Handle to parent window
ofn.lpstrFile = array;
ofn.nMaxFile = MAX_PATH;

GetOpenFileName(&ofn);
