Ah, I used your code, but it still crahses. However the error says that there is a type_check failure. image type is {71,114,97,112...}
I am using a supported image type, so what is up?
Your GraphicType value needs to be one of these constants, from CxImage.ew:
-- Image types. Used with CXI_LoadImage and CXI_SaveImage. global constant CXI_FORMAT_UNKNOWN = 0, CXI_FORMAT_BMP = 1, CXI_FORMAT_GIF = 2, CXI_FORMAT_JPG = 3, CXI_FORMAT_PNG = 4, CXI_FORMAT_ICO = 5, CXI_FORMAT_TGA = 6, CXI_FORMAT_PCX = 7
I suspect you're passing it a sequence of "Grap..." something. (At least that's what your error message seems to indicate.)

Thanks, it appears to be working now, however, the image is displayed as a grey box, and it paints over the other controls. I have tried repaintRect, but it still shows the grey box. Here is the new code
procedure Add_Hero_WalkGfx(integer self, integer event, sequence parm) fName = getOpenFileName(EDWin,file,GraphicType) if length(fName) = 0 then return end if HeroWalk_Gfx = CXI_LoadImage(fName,CXI_FORMAT_UNKNOWN,0) HeroWalk_Gfx = createDIBFromCXImage(HeroWalk_Gfx) repaintRect(EDWin,750,220,64,64) end procedure setHandler(Hero_WalkGfx_Add,w32HClick,routine_id("Add_Hero_WalkGfx")) procedure EDWin_onPaint(integer self, integer event, sequence parm) if HeroWalk_Gfx != 0 then copyBlt(EDWin,750,220,HeroWalk_Gfx) end if end procedure setHandler(EDWin,w32HPaint,routine_id("EDWin_onPaint"))
