I am stumped trying to find "CoInitialize".

I am trying to include the shortcut routines provided by Donkey.

However, the link step can not resolve "CoInitialize",
nor can it resolve "CoCreateInstance"

I have tried searching everything I have to locate these two
modules, but still come up with nothing.  Frankly, I do not
even know what these two functions accomplish.

Below, I have included my code, as well as the link information.

Can anyone tell me what I am doing wrong?

Hi Chip

CoInitialize and CoCreateInstance are Windows APIs which are in the system file ole32.dll, so you need to add that to the list of DLLs given to the linker.

You can find out what system DLL the various Windows APIs are in, and what those APIs do, using the Microsoft SDK which is available on-line.

Here is a link to CoInitialize in the SDK:-
http://windowssdk.msdn.microsoft.com/en-us/library/ms678543.aspx
and here is a link to CoCreateInstance in the SDK:-
http://windowssdk.msdn.microsoft.com/en-us/library/ms686615.aspx

If you look down at the bottom of the SDK specification for these APIs you can see the words: "Library: use ole32.lib".  This indicates that they are in ole32.dll (GoLink does not need the lib file referred to here, because it looks inside the DLL itself to identify the function).

Jeremy,

Thank you, that seemed to solve the problem.

When I first downloaded and installed  the SDK,
I looked for directrions or information on what
was contained.  I never did find anything that
made sense to me, nor explained what was
contained in all of the directories.

My best shot at finding most data has been to
do a string search on all files in masm, goasm,
and now the SDK to see if I get some sort of
"hit".  I know that this sound outrageous, but
I find the overall masm and SDK documentation
absolutely appaling. 

(Perhaps my shortcoming is that I have never
programmed in any of the various "C" languages. 
Yet, all documentation is oriented to these
particular languages.)

You might find the "contents", "index", "search" tabs at the bottom of the left hand side of the SDK screen handy for finding the right thing.  Once you have found something if you click on the "sync contents" toolbar button, this gets you to the correct place in the contents.

I agree that having the samples in "C" is a pain, but as you progress you will find that you get to understand these and are able to follow them!

Hi Chip,

You are like me, I had no experience in any languages when I began in assembler, this can actually be an advantage as you have no prejudice or preconceptions enterring into programming. I found that when I began to learn C years later that I brought alot of assembler bagage with me and had to temporarily "unlearn" certain things in order to make progress in C, I have since abandonned the effort as GoAsm provides me with just about everything I need for x86 programming, I only use C now for a small amount of ARM programming for my PDA. It did not take long however to learn to read and for the most part understand enough C to navigate and use th SDK, in that case a little goes a long way and you will soon find that you can quickly skim the examples and understand them.
