1. CxImage User Input

Hello,

I tried searching the code for the old cxImage code that allowed a user to input a graphic file using the cximage, but it isn't showing up. Does anyone have the code for the use of the cximage library? I remember the code being something like this

function createDIBFromCXImage() 
--eu code 
end function 

However that's all I can remember.

OK, However whenever I try to load a image, my program freezes, here's my code.

 
Hero_WalkGfx_Win = createEx(Window,"",Tab_Hero,460,50,64,64,{WS_CHILD,WS_CLIPSIBLINGS},0) 
 
object HeroWalk_Gfx 
HeroWalk_Gfx = 0 
 
procedure Load_HeroWalk_Gfx(integer self, integer event, sequence parm) 
	fName = getOpenFileName(Hero_WalkGfx_Win,file,GraphicType) 
	 
	if length(fName) = 0 then 
		return 
	end if 
	 
	HeroWalk_Gfx = CXI_LoadImage(fName,CXI_FORMAT_UNKNOWN,0) 
	 
end procedure 
setHandler(Hero_WalkGfx_Load,w32HClick,routine_id("Load_HeroWalk_Gfx")) 
 
procedure Paint_HeroWalk_Gfx(integer self, integer event, sequence parm) 
	transBlt(Hero_WalkGfx_Win,0,0,HeroWalk_Gfx) 
end procedure 
setHandler(Hero_WalkGfx_Win,w32HPaint,routine_id("Paint_HeroWalk_Gfx")) 

There's more code to obviously, but this is the part that counts, I'm pretty sure. I remember they're being some kinda of code Greg wrote so that user input images would work. What I want is for the user to load a image and then have it displayed in the window. However, when I tried loading an image, my program froze.

OK I did, and now it dosen't freeze anymore, but my image isn't showing up on the window.

That didn't work either. I remember somebody had some code written so that it would allow for this. I remember it being something like this.

function createDIBFromCXImage(atom hDib) 
return hDib 
end function 

I don't rememeber all the code in the function, but I remember that is what I had that showed the image in the window. I think Greg wrote it, but I'm not sure.

function createDIBFromCXImage(atom hDib) 
return hDib 
end function 

However, I was able to grab it from google cache, and I have saved them here:

Hero_WalkGfx_Win = createEx(Window,"",Tab_Hero,460,50,64,64,{WS_VISIBLE,WS_CHILD,WS_CLIPSIBLINGS},0) 

Actually it wasn't that it, it wasn't visible, I forgot to add repaintWindow when I drew the image to the window.
