Call DLL > Ordinal value

[sandin]

I hope I haven't bored you all with all theese questions, but I'm still a newbie, and I wanna learn how to program in AI.

I read this in help files:

DllCall ( "dll", "return type", "function" [, "type1", param1 [, "type n", param n]] )

so, I managed to open, call, and close DLL file, but if I want ti use an option from it, I would have to know the function name or ordinal value, right? So is there a way for me to find out what ordinal values DLL file contains, and which functions it does?

Example:

DllCall("shell32.dll", "none", 62, "hwnd", 0, "ptr", DllStructGetPtr($stString), "int", DllStructGetSize($stString), "ptr", DllStructGetPtr($stIcon))

...opens an icon selection window (called by shell32.dll file, function no. 62). Now, I could use this only if I knew that no. 62 calls icon selection window, but what if I didn't knew that, is there a way for me to find out what functions DLL file contains so I can use them in autoit (and I'm not talking about main winxp files, I'm talking about all dll's).

Not sure what you're asking for. Perhaps you want to read this first?

for example, I have virtual.dll file, and I know what's he capable of. But if I use:

DllCall ( "virtual.dll", "none", ###)

I wouldn't know what to put in ### spot, to make it do it's function.

so, is there a way for me to check what functions this virtual.dll file contains, something like:

52 = minimize window

53 = select all

54 = choose a directory

etc...

(theese are all just examples)

heh... it's hard to explain

Ask the developer of the DLL to provide you with the parameters... otherwise, if there's more than just the function call parameter, you're pretty much SOL.

thank you for the reply, I'll try to find a way to avoid using dlls which doesn't belong to windows's basic dlls.
