Hi Sunil,

You could use the FindFirstFile Function[^] and FindNextFile Function[^]

In addition to the other replies pointing you at FindFirstFile, what is empty?

Does it count as empty if there's only directories there? What if there are directories, but they have / have not got any contents themselves?

You don't need to answer me, but you need to ask and answer this question for yourself.

Yeah the case can be considered.
But the directory is created by my application and the files are also created by my
application.
My files doesnt contain any extension.
I do not understand how I can use FindFirstFile.
FindFirstFile is giving me the valid handle.But FindNextFile is always returning 0, even
files are present.
what is the reason behind it?

If you're using MFC you might try something like this:

BOOL DirHasFiles(CString csDir)
{
  if (csDir.Right(1) != "\\")
    csDir += "\\";

  csDir += "*.*";

  BOOL bDirHasFiles = FALSE;
  CFileFind ff;
  BOOL bWorking = ff.FindFile(csDir);

  while (bWorking)
  {
    bWorking = ff.FindNextFile();
    if (ff.IsDirectory())
    {
      if (ff.IsDots())
        continue;
    }
    else
      bDirHasFiles == TRUE;
  }


  return bDirHasFiles;
}

Edit:
For plain WIN32, have a look here:

I am using VC++ 6.0.I am not to conversant with VC++.

I have a project where i need to extract the data from the database then provide preview of the same data & then print the same independently. The no. of page could be more than one if the data is more. To achieve this, I have referred to below link for print & preview in MFC. I found this project very useful to cater to my requirement.

http://www.codeproject.com/KB/printing/printlib.aspx

In this project, preview or print button, i am unable to understand how it adds 2nd page. i have a requirement where if data is more than 1 page then it should automatically go to next page. How would i do that in VC++ in the above project.

Kindly indicate if you would need some more info.

I've done next to nothing in regards to printing via code, but one of the last times I did need to print something, I wrote the contents of my database query to an HTML file, and then navigated to that file using CHtmlView.

Hi,
im creating combobox ctrl dynamically Thru code but not from resource...and Pls let me know how can i increase the height of the ctrl based on the font...ie if the font is small ctrl should be small else if the Font is bigger Ctrl should increase....

i used SetFont() the size of the ctrl is increased and the Font of the items in the Dropdownlist was also increased but the selected item font is not changed...

m_ComboBox.Create(
WS_CHILD|WS_VISIBLE|WS_VSCROLL|CBS_DROPDOWNLIST,
CRect(5, 10, 20, 50),
pParentWnd, IDC_COMBOBOX);

and even i tried using GetComboBoxInfo and obtained HWND hwndItem handle for Editbox but i want to know how can i setfont for the same...

Just set the font size as mentioned below with m_Font as member.
Doing so will increase the height of the combo box according to the font size and font type
To increase the width, you can SetWindowPos or MoveWindow functions .

CDC *pDC = GetDC();
    LOGFONT lFont;
    memset(&lFont, 0, sizeof(lFont));
    lFont.lfHeight = 34;
    lFont.lfWeight = FW_NORMAL;
    lFont.lfOutPrecision = OUT_TT_ONLY_PRECIS;
    strcpy( lFont.lfFaceName, _T("Lucida Sans Unicode"));
    // Set the Font
    m_Font.CreateFontIndirect(&lFont);

    // Set the specified font for the edit ctrl.
    m_pComBo->SetFont(&m_Font);

You may send the WM_SETFONT message to the the combo's edit box (that is another window), i.e.:

call GetComboBoxInfo [^] to obtain the handle of the edit box ( hwndItem member of the COMBOBOXINFO struct).
Send the WM_SETFONT message using the found handle.

I tried using the below code..

COMBOBOXINFO cbi;
cbi.cbSize = sizeof(COMBOBOXINFO);
m_ComboBox.GetComboBoxInfo(&cbi);
::SendMessage(cbi.hwndItem,WM_SETFONT,(WPARAM)pFont->m_hObject,TRUE);
::SendMessage(cbi.hwndCombo,WM_SETFONT,(WPARAM)pFont->m_hObject,TRUE);
::SendMessage(cbi.hwndList,WM_SETFONT,(WPARAM)pFont->m_hObject,TRUE);

Where pFont is a CFont* in which im having the bigger font..
All are changed except the Font in the selected item in the combobox..

The font in the selected item of Combobox is also changed but when i click on the combobox the font of the selected item is changing to older font ie small font...

Please help me regarding the same..

The other thing I would recommend you look at is MapDialogRect[^], so you can use dialog box units, just like you would if you're doing a resource driven layout, and get them transformed to pixels like CreateWindow uses.

Use GetDefaultPrinter() to get the name of the default printer. If you want the user to select a different printer, use PrintDlg().

The steps:

1. StartDocPrinter
2. StartPagePrinter
3. WritePrinter
4. EndPagePrinter
5. repeat 2, 3, 4 for as many pages as necessary
6. EndDocPrinter

When you are trying to print a text file directly to a printer, there will be no format information such as font, color, etc sent to the printer. The printer will use its default font to print the text file in its natural text flow. The result is not pretty.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
