C / C++ / MFC

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.

Your questions is not really clear.

You can see the mouse state Using GetKeyState function. You can know the mouse position using GetCursorPos

Check if this helps?[^]

I use WinInet + MFC to post some form to the web server.

I add the log module, at last found this:

1. call CInternetSession::GetHttpConnection
2. call CInternetSession::OpenURL
3. call CHttpFile::SendRequest
4. call CHttpFile::QueryInfoStatusCode (block)

at the step 4, some computer is ok, but some computer is block here.

when is block , the last error code:12002 ,it means time out.

I search in this web and google, but usually saied that's the WinInet's bug.

What should I do?

I have a CFormView with a large bitmap of a form.
I lay an edit box on top of the form where the user would
type in a value.

The image of the form has a vertical line that separates the
cents from the dollars. The edit box, even though its white
or light shaded, covers or blocks that vertical line of the
form. How can I make the edit box see-through so that you
still see the background of the form in the edit box?

I tried making the edit box transparent or the bitmap transparent
or one transparent and the other not and no combination is
working.

Please any response any one can give me will be greatly appreciated.

Sincerely,
Danielle

What about two edit boxes, one for dollars and the other for cents? Or, what about adding the vertical line to the edit box?

I thought about that. Two edit boxes just complicates it. You type in a
number 1234 and then tab off to type in the cents. Its faster to just type
in the number as is.

I thought about adding a vertical line to the edit, but have not figured out
a nice, simple, clean way of doing that.

I found a program on the web that looks like it has the feature Im looking
for. Its just a simple edit box and you can see the form in the background
of that edit.

If you know how to draw that line in the edit box, that would be great.
