Introduction

You can execute another program from your application without the need to attach the execution file with your program. The exe file will be stored in the application resources as a bitmap image, and in the runtime mode this image will be written in an exe file.

Once the exe file has been created, there is no problem to run it.

These steps will explain for you how to do that:

1. From your resource view, insert new resource type, let's call it "EXE".
2. From the "EXE" type, import the execution file you want to include in it.

Until now, you have loaded the Execution file in your resources, and you need write it in an execution file to be ready for running. Create new function in your program, let's call it Run(), like this:

  bool Run()
   {
    CFile f; //This is the file which will be used  as an exe file  
    char* pFileName = "Execution.exe";
    if( !f.Open( pFileName, CFile::modeCreate | CFile::modeWrite, NULL ) )
    {
        AfxMessageBox("Can not create file!");
        return 0;
    }
        CString path = f.GetFilePath();
    HGLOBAL hRes;
    HRSRC hResInfo;
        //Get the instance handle for this app   
    HINSTANCE insApp = AfxGetInstanceHandle();
        //find the handle for the EXE resource    file
    hResInfo = FindResource(insApp,(LPCSTR)IDR_EXE4,"EXE");
    hRes = LoadResource(insApp,hResInfo );   // Load it

 
        //Calculate the size of the exe file 
    DWORD dFileLength = SizeofResource( insApp, hResInfo );  
    f.WriteHuge((LPSTR)hRes,dFileLength);  //write it 
    f.Close();
    HINSTANCE HINSsd = ShellExecute(NULL, "open",path, NULL, NULL, 
                                        SW_SHOWNORMAL); //Execute it.  
    return 1;
 
   }

That's all.
