Font Size Problem in Edit Control [SOLVED]

vishalgpt

Hi to all, I am facing a strange problem, i had asked for help in the forum few days before. But due to certain delays i was unable to show the code. Here is the code. My Problem is with hindi fonts. When i substitute the the LOGFONT.lfHeight with 0(Zero) then everything works fine, But when i change the size of lfHeight to anything greater or lesser than zero, the Hindi fonts is displayed very small. How to solve this issue.

case WM_INITDIALOG:
LOGFONT lf;

HFONT cFont;
HWND target = GetDlgItem(hwnd,IDC\_STATIC1);
HFONT hFont = (HFONT)GetStockObject(DEFAULT\_GUI\_FONT);
GetObject(hFont, sizeof(LOGFONT), &lf);

lf.lfHeight = 0;
cFont = CreateFontIndirect(&lf);
SendMessage(target,WM\_SETFONT,(WPARAM)cFont,MAKELPARAM(TRUE,0));
SetWindowText(target,\_T("C:\\\\Program Files\\\\অভিধান: ইংরেজী\\\\सरकारी &&"));
break;

sorry for posting twice.

Regards, Vishal

You need to convert the point height of your font into device units with the following formula:

lFont.lfHeight = MulDiv(nFontHeight, GetDeviceCaps(hDC, LOGPIXELSY), 72);// height of font

See the MSDN page for CreateFont()[^] for more information.

i am using

-MulDiv(iPointSize,GetDeviceCaps(GetDC(target),LOGPIXELSY),72);

Where iPointSize is the size of font; But, the results are not up-to mark. If i specify the

lFont.lfHeight = 14

then, the text in english font is ok but the text in hindi font seems like the lfHeight is 8. But if i specify the

lFont.lfHeight = 0

Whether hindi or bengali or chinese every font is in same height and looks good, but their sizes are big. I am using default MS Shell Dlg Font.

Try the positive value returned by MulDiv() and/or one of the other fonts, if possible one that was designed for Hindi characters.

Yes sir, i had tried. Mangal gives positive result for hindi fonts. And Trebuchet MS for others. Sir, i have one small doubt. Do we have to distribute these fonts with application or these are system default fonts available on windows. and (negative) -MulDiv() gives good result instead of (postive) MulDiv(). Is it OK. Please guide.

I'm afraid I don't have the answer to these questions, you will have to investigate the rest for yourself.

From memory, a negative lfHeight means "points" as opposed to pixels, but you'd have to check the definitions on msdn for LOGFONT. Iain.
