Run at StartUp option

I am using Borland C++ Builder 4.0 Pro.

I am trying to add an option to an application on a 'preferences' form using a checkbox that the user can either have the app load on Windows Starup, or not.  I am having no luck at all.  I have tried a Registry Entry that does not function.  I have looked all over the web, my reference books, and the Borland Newsgroups.  I am hoping that someone here can help me out.

I have come to realize that it seems that if I can add (and delete) a shortcut into the Windows Startup directory, then I will have the functionality that I need.

All I need is some sort of an example function I can study, or a snippet of someone's code that I can look at. So I can add this option via a checkbox.

Thank you in advance for any help offered.

The easiest way would be to place an entry under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - it has to be of the form

"Arbitrary Value Name" = "c:\\mypah\\myprog.exe"

BTW, if you want to delve deeper into where to place entries to run a program at startup, get check out "Autoruns" and get the source code ar http://www.sysinternals.com/ntw2k/source/misc.shtml#autoruns

I have tried going through the Registry, without success.  I have placed my entry in both HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run  and HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run.  Neither work.  I can get my app to show up in Start -> Run -> MsConfig | Startup, but yet the app does not start.

I manually put a shortcut into the Run->Programs->StartUp directory and that works perfectly, therefore I am looking for a way to add (and delete) a shortcut into that directory through my app, with a checkbox.

Well i cannot understand why the registry approach doesnt work, are you sure you are specifying the correct path ?

StartMenu approach is preferred over registry one when you want the user to be able to "see" that the app is being started up. Its more like user consent etc.

You can create a shortcut programatically as follows, this is VC specific code , you have to change it to BC specific

BOOL CreateShortcut(CString linkFileName, CString linkToFile)
{
     HRESULT hres;
     IShellLink* pIShellLink;

     hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER,
     IID_IShellLink, (LPVOID *)&pIShellLink);

     if (SUCCEEDED(hres))
     {
          IPersistFile *pIPersistFile;
          hres = pIShellLink->SetPath(linkToFile);
          if (!SUCCEEDED(hres))
          hres = pIShellLink->QueryInterface(IID_IPersistFile,
          (LPVOID *)&pIPersistFile);

          if (SUCCEEDED(hres))
          {
               USES_CONVERSION;
               hres = pIPersistFile->Save(T2OLE(linkFileName), TRUE);
               pIPersistFile->Release();
          }

          pIShellLink->Release();
     }
        return TRUE;
}

linkFileName should be path to startmenu which can be found by using

SHGetSpecialFolderPath with CSIDL = CSIDL_STARTMENU.

hope this helps ..

>> linkFileName should be path to startmenu which can be found by using

i wanted to say linkFileName should be path to startmenu plus link name.

There are other paramters for the link that you can set thru IShellLink, see MSDN for details.

Thank you for the help.  If I could have added a comment to the original question, I would have asked for some help in reversing (deleting) the CreateShortcut function.  I am having a rough time trying to delete it, or getting information on how to go about that.

Well, thanks though for the info.  :-)
