How to load a DLL from a resource file and save it to disk (Views: 27)
Problem/Question/Abstract: Is it possible to copy a DLL into my own executable using the IDE only for exporting it after in my program? For example, I create an executable Test.exe and in the IDE I want to attach a resource that contains the DLL. And when my program is running I can export this resource to put a file on my hard disk. Is there a way to do that? Answer: Create a file called "mydllres.rc". Edit it and insert the line MYDLL RT_RCDATA "Mydll.dll". Then call the Borland compiler for resouces (you may need to adjust the paths) with BRCC32 mydllres.rc . This will produce a output file called mydllres.res. Under the implementation header in the main unit add the following: {$R mydllres.res}. This will add the resource to the project. The following procedure will save it to a file: procedure savedll; var myres: TResourceStream; begin myres := TResourceStream.Create(hInstance, PChar('MYDLL'), RT_RCDATA); myres.SaveToFile(ExtractFilepath(Application.exename) + 'mydll.dll'); myres.destroy; end; |
