I need to program something that reads raw data out of it's own EXE in a reliable manner.

In the documentation I have read thus far, everything suggests I should use the FindResource API. However I find myself a little lost about it's use and how to supply it these "Resources", since all the documentation is for VC++ and VC++ hides these aspects from the programmer.

I'm sure it's simple. Can somebody give me a quick example?

Here is my code to load the resource called "MyData" from self:
Code:
invoke FindResource,0,'MyData',RT_RCDATA
mov [ResourceHandle],eax    


How do I provide this code the "Resource" it needs?

Thanks in advance. Smile

You can get the resource section from the PE headers.

And what do I have to call "MyData" there for it to find the right thing?

Hi, if you read the remarks on the MSDN for FindResource you see 'MyData' is the identifier for the resource, whether it is a string or an integer identifier, so pass the ID that defines that resource, in C/C++ you would use the MAKEINTRESOURCE macro which just casts int to char * but in asm just pass the value of the ID or the address of a string.

If you don't know the ID you can find the address of the resource section (from the PE headers) and go from there.

There is also EnumResourceNames.

Here is an example of how to use FindResource and how to enumerate all the resources of a module.

You call FindResource and pass the returned value to LoadResource
Code:
invoke  FindResource, 0, 'MyData', RT_RCDATA
mov     [ResourceHandle], eax
invoke  LoadResource, 0, eax
mov     [ResourceData], eax ; <-- this is what you want
