How To Use Custom Fonts

February 24, 2008

Hi Guys...i am learnning masm...and have managed to learn howto skin windows, buttons as well as some other controls.

I have even managed to design some small keygen templates. but guys i need some help regarding using custom fonts both open type as well as True Types

I'll be grateful for any help

Quickly made a radasm bone:

FontFromResources.rar

It won't save the font to hdd, but be aware, that 'AddFontMemResourceEx' doesn't work on Win98.

nice. too bad that the AddFontMemResourceEx API is not supportet for win me/98... Maybe better use AddFontResource API ??? (After using the font it shoulde be removed with RemoveFontResource?)

is there also a method for win 98/me systems? Maybe there is a method installing a font over commandline?

Thank You UFO-Pussy....Atlast...i was expecting the answer from you and Ziggy only...

Thanks Again

Here's a code I've found on MASM board, which should work for 98 (AddFontResource):

Instal_Font.zipBut you have to write it to system's font dir and register it

Tho I got it, after Killboy found a c++ snippet about that ^^

May be similar to what UFO posted (not checked) but I have used the following to register a new font (not removed afterwards though)

ResExtractFile proc hInst:DWORD, Resource:DWORD, ResMarker:DWORD, Destination:DWORD
LOCAL hRsrc:DWORD
LOCAL hResource:DWORD
LOCAL dwResSize:DWORD
LOCAL hFile:DWORD
LOCAL dwWritten:DWORD
LOCAL lpfResource:DWORD
LOCAL hkResult:DWORD
LOCAL dwDisposition:DWORD
LOCAL dwLength:DWORDinvoke FindResource,hInst,Resource,ResMarker
.if eax == NULL
  not eax
.else
  mov hRsrc,eax
  invoke LoadResource,hInst,hRsrc
  .if eax == NULL
	not eax
  .else
	mov hResource,eax
	invoke SizeofResource,hInst,hRsrc
	mov dwResSize,eax
	invoke LockResource,hResource
	mov lpfResource,eax	invoke CreateFile, Destination, GENERIC_WRITE, 0, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL
	mov hFile, eax
	invoke WriteFile, hFile, lpfResource, dwResSize, ADDR dwWritten, NULL
	invoke CloseHandle, hFile	invoke lstrlen, addr szFileName
	mov dwLength,eax
	invoke RegCreateKeyEx, HKEY_LOCAL_MACHINE,
		ADDR szSubKey,
		NULL,
		NULL,
		REG_OPTION_NON_VOLATILE,
		KEY_WRITE,
		NULL,
		ADDR hkResult,
		ADDR dwDisposition 	.if eax == ERROR_SUCCESS
		invoke RegSetValueEx, hkResult, addr szValueName, NULL, REG_SZ, addr szFileName, dwLength
		invoke RegCloseKey, ADDR hkResult
	.endif	invoke AddFontResource, addr szFileName
	invoke SendMessage, HWND_BROADCAST, WM_FONTCHANGE, NULL, NULL
  .endif   
.endif
ret
ResExtractFile endp

The font file is added to the resources with:

FontFile BINFILE fonts\<font_name>.TTF

Tho I got it, after Killboy found a c++ snippet about that ^^

Any chance Killboy can repost this C++ code snippet?

February 25, 2008

That was the snippet I got:

HINSTANCE h=AfxGetInstanceHandle(); 
ULONG nFont = 1; 
HRSRC hr=FindResource(h, "#4" , RT_FONT); 
HGLOBAL hg=LoadResource(h,hr); 
LPSTR lp=(LPSTR)LockResource(hg); 
DWORD dwSize = SizeofResource(h, hr); 
HANDLE handle = AddFontMemResourceEx(lp, dwSize, 0, &nFont); 
// TODO: Add extra initialization here 
LOGFONT lf; 
memset(&lf, 0, sizeof(LOGFONT));   // Clear out structure. 
lf.lfHeight = 20;				  // Request a 20-pixel-high font 
strcpy(lf.lfFaceName, "LadderKK");	//	with face name "Arial". 
m_font.CreateFontIndirect(&lf);	// Create the font. 
GetDlgItem(IDC_EDIT1)->SetFont(&m_font);

Still find it easier to read compiled c++ stuff than its source

February 25, 2008

Hehehe, for me its the exact opposite. I really should learn ASM these days, as all I use is C/C++.

Thanks for the snippet though, it will come in handy

February 25, 2008

@UFO-PU55Y

bro i'm using your code snippet but itn not setting the font....

I'm not getting any errors or warnings and the font is being set to Arial.

I'm using WinASM as IDE and Masm v6. on Windows Vista Ultimate

(

DlgProc proc hWin:DWORD,uMsg:DWORD,wParam:DWORD,lParam:DWORD
	mov	eax,uMsg	.if	eax == WM_INITDIALOG
		invoke	LoadIcon,hInstance,200
		invoke	SendMessage, hWin, WM_SETICON, 1, eax
		invoke FindResource,NULL,300,RT_RCDATA
		mov fntinfo,eax
		invoke LoadResource,NULL,eax
		invoke LockResource,eax
		mov pfont,eax
		invoke SizeofResource,NULL,fntinfo
		invoke AddFontMemResourceEx,pfont,eax,0,offset nfont
		invoke CreateFontIndirect,offset lfFont
		mov hfont,eax		invoke GetDlgItem,hWin,1002
		invoke SendMessage,eax,WM_SETFONT,offset hfont,1	.elseif eax == WM_COMMAND
		mov	eax,wParam
		.if	eax == IDB_EXIT
			invoke	SendMessage, hWin, WM_CLOSE, 0, 0
		.endif
	.elseif	eax == WM_CLOSE
		invoke	EndDialog, hWin, 0
	.endif	xor	eax,eax
	ret
DlgProc endp

Sorry i got my error

Me silly

Anywyas Thanks again...i've learnt alot here and hope to learn more....

Another Problem:

If you have a font file which is named not correctly. How to get the correct font name so that you can use "CreateFont..." Funktion? Because the fontname seems to be stored inside the fontfile...

Any idea?

You'll see the correct name by simply doubleclicking and opening with system's font viewer.

I renamed a bunch of font files with their correct font name in order to simply create them

later on with their filename w/o extension as parameter.

But if you're after a code to retrieve the correct names:

http://www.codeguru.com/cpp/g-m/gdi/fontha...le.php/c3659__1

But that would prolly mean a ****load of code, coz truetype and opentype fonts are too

different to handle :X

EDIT/

Tho I just read about an undocumented GDI API call: GetFontResourceInfo !

But no further info about what parameters it needs. I only read the comment

to fire up SoftIce to check this function out for yourself.. lol

thank you ufo! i think the sourcecode getfontnamefromfile.cpp is interesting. i want build in this function additionally. because ttf files are used often. maybe i will translate it to masm.

But first i will take a look to this GDI API GetFontResourceInfo....

--> http://www.autoitscript.com/forum/index.php?showtopic=30552

...very interesting...

I figured out how to use the GetFontResourceInfoW function. Here is the masm code, how to get the correct fontname from any fontfile...

GetFontName proc uses edi esi ebx _fontfile:dword,_buffer:dword,_buffersize:dword	LOCAL local_hlib		:DWORD
	LOCAL local_fontfile_wide[1024]	:BYTE
	LOCAL local_sizeof_buffer	:DWORD
	LOCAL local_fontstruct[92]	:BYTE;unknown structure
;---set return value to 0---
	xor ebx,ebx	invoke LoadLibrary,chr$("gdi32.dll")
	mov local_hlib,eax
	invoke GetProcAddress,eax,chr$("GetFontResourceInfoW")
	.if eax!=NULL
		mov edi,eax	;---convert ansi to unicode---
		invoke MultiByteToWideChar,0,MB_PRECOMPOSED,_fontfile,-1,addr local_fontfile_wide,sizeof local_fontfile_wide
	;---add font to Windows font table---
		invoke AddFontResource,_fontfile
	;---call undocumented GetFontResourceInfoW---
		mov local_sizeof_buffer,sizeof local_fontstruct
		lea ecx,local_sizeof_buffer
		lea eax,local_fontfile_wide
		lea esi,local_fontstruct
		push 2			;1=get fontname (works not always good) / 2=get structure with fontname
		push esi		;structure
		push ecx		;size of recievebuffer
		push eax		;font filename
		call edi		;GetFontResourceInfoW
		.if eax==TRUE
			mov ebx,eax	;modify return value to 1			add esi,28	;point to correct unicode fontname		;---convert unicode to ansi---
			invoke WideCharToMultiByte,0,WC_COMPOSITECHECK,esi,-1,_buffer,_buffersize,0,0
		.endif
	;---remove font from Windows font table---
		invoke RemoveFontResource,_fontfile	;---free loaded dll---
		invoke FreeLibrary,local_hlib
	.endif	mov eax,ebx
	ret
GetFontName endp

February 26, 2008

Great ! I also tried it, but missed the AddFontResource and only tried it with

unregistered fonts.. dooh. Ofc I didn't get **** returned from that function all the time ^^

Cool that you figured it out ! :cool:

February 26, 2008

but this function is only for XP systems where gdi32.dll contains "GetFontResourceInfoW"

in win98`s gdi32.dll its just called "GetFontResourceInfo". So maybe there are no widechars. I dont have win98 system. so i cant figure it out...

February 26, 2008

Why dont you use the ascii version by default ? Is there no A-version on XP ?

nop. at least I couldn't find it. M$ ftw. Edited February 26, 2008 by Ufo-Pu55y

February 27, 2008

Which means this particular function is WinNT specific, since Unicode (wide char) functions can't natively be used under Win9x. And from my test app, it crashed when using a "A" alternative. Plus I have read somewhere that it is a native WinNT function..

i noticed that using:

SendMessage(HWND_BROADCAST,WM_FONTCHANGE,0,0);

is not good after installing a font, even microsofts says, that its better when you use it after installing a font.

But it causes strange bugs.

Much better to use PostMessage... ;-)

no, the problem is not only the SendMessage API.
