What is FUNC???

[localmotion34]

i have this code block from source DougieM wrote for a custom control.  I get a "sytax error" at a statement like this:

Code Select Expand

; select type of background if gif is transparant
  .if FUNC(GetObject,[ebx].backg,0,0) == sizeof LOGBRUSH   <<-------- DIES RIGHT HERE
      invoke FillRect,memdc,addr [ebx].rc,[ebx].backg; if a brush has been sent in backg
  .else                                              ; fill with brush
      invoke CreateCompatibleDC,hdc
      mov backdc,eax
      invoke SelectObject,backdc,[ebx].backg        ; or a bitmap
      push eax                                      ; then copy backg bmp into our memdc
      invoke BitBlt,memdc,0,0,[ebx].rc.right,[ebx].rc.bottom,backdc,0,0,SRCCOPY   
      pop eax
      invoke SelectObject,backdc,eax
      invoke DeleteDC,backdc
  .endif

Why is the compiler dying right here at this point?

hi

is a invoke macro



  FUNC MACRO parameters:VARARG
        invoke parameters
        EXITM <eax>
      ENDM

localmotion34,

Here is a quick example :

Code Select Expand

mov hModule,FUNC(GetModuleHandle,0)

is equivalent to :

Code Select Expand

invoke GetModuleHandle,0
mov hModule,eax

Thanks to you both!!!

i included the macro, and boom, the LIB compiled.  There are so many macros for MASM, i'm having trouble reading much of any code without having to constantly search for macro.inc files.

you must simply search in the board or with google for the appropriate macro!

and it more simply to coding if one macros uses :U

localmotion34,

Never hesitate to post here your questions. To study the basic principles of MASM macros, have a look at here :

localmotion34,

Use the existing HELP FILE in masm32 for all of the high leel help. Thats what its there for. MASM is a macro assembler and this is used to simplify much of the code for people leqarning assembler programming.
