DLL and EXE

[Shanheavel]

Hello.

I'm trying to add *.DLL into my program *.EXE with Autoit3 Wrapper.

I'm using resource.au3 from topic. If somone has easier idea to add DLL into EXE then please write.

...
#include "resources.au3"

;Add MyLib.dll 
#AutoIt3Wrapper_Res_File_Add=MyLib.dll, rt_rcdata, LIB

;Get MyLib.dll as string
$LibAsString = _ResourceGetAsString("LIB")

;Try to open this DLL
DllOpen($LibAsString)

...
;Use DLL

It doesn't work. I can save "LIB" to file *.DLL without problem but I need to use library from memory (from EXE).

Can someone tell me how to do it, please?

Why are you getting the resource as a string? What makes you think you can execute a string? Use _ResourceSaveToFile() instead.

I think you don't understand me

I want to use DLL without saving it to file. I need DLLOpen from resource "LIB".

Maybe we understand what you want, but not what the problem is with saving the DLL to a file first before using it? Edited February 26, 2011 by Jos

I'm making some program and I don't like when people edit my DLLs using program like Winhex. It's safer method.

That doesn't make much sense for 2 reasons:

1. They could "patch" your script as easy as any other file.

2. You could FileInstall() the DLL with each run so whatever they change will be overwritten each time you start the script EXE.

You missed link to this post from my Resource topic

When I use the DLLs in the normal method (by DllCall)

DllOpen("SomeLib.dll")
DllCall("SomeLib.dll, "int", ...)

it works great.

But when I use:

Dim $DllBinary = ... ;My DLL binary code from MemoryDllGen.au3 
MemoryDllOpen($DllBinary) ;It returns 0   :(
MemoryDllCall($DllBinary, "int",...)
MemoryDllExit()
...

It doesn't work.

[PsaltyDS]

DllOpen() requires a string file name. DllCall() requires either the string filename or a handle to the already open DLL. You can't pass it a binary like that.

The correct way to do it would be to save $DllBinary to a .dll file and then use that. But you knew that...

PsaltyDS meant to say DllCall(), surely.
