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..

When i changed the property of combobox from CBS_DROPDOWNLIST to CBS_DROPDOWN while creating combobox dynamically....but the CBS_DROPDOWN gives editablecombo which is not accepted in my case..

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.

To format text you have to print it in graphics mode. Get the printer DC and output to that DC. That way you can choose your font, size, etc. and arrange text to appropriate locations.

One way would be to use ShellExecute(hWnd, "name of txt file", "print", ...).
