Extracting Resource Data from an Exe

Title: Extracting Resource Data from an Exe
Question: Article 832 mentions how one can put Files into an Exe. This shows you how you can get it out
Answer:
I've written a simple function that does this for you, just cut and paste (some detail is below)
procedure ExtractToFile(Instance:THandle; ResID:Integer; ResType, FileName:String);
var
ResStream: TResourceStream;
FileStream: TFileStream;
begin
try
ResStream := TResourceStream.CreateFromID(Instance, ResID, pChar(ResType));
try
//if FileExists(FileName) then
//DeleteFile(pChar(FileName));
FileStream := TFileStream.Create(FileName, fmCreate);
try
FileStream.CopyFrom(ResStream, 0);
finally
FileStream.Free;
end;
finally
ResStream.Free;
end;
except
on E:Exception do
begin
DeleteFile(FileName);
raise;
end;
end;
end;
You pass in the Instance of the exe or dll (the same application would just be Application.Instance or Application.Handle, for a dll you got to get that yourself :)
ResID is the same ID that was assigned in the resource
ResType WAVEFILE, BITMAP, CURSOR, CUSTOM - while this should work with all Resource Types, I've only have success with CUSTOM
FileName the file you would like to create from the resource
It's pretty easy, create a resource stream, create a file stream, copy what's in the resource stream to the file stream.
