Creating a desktop icon from code

Anyone know how to do this?

You need COM.....I posted an example quite a while ago if you want to search..

An easier way is to use Windows Scripting Host like this;

Code:

try{

var oShell = new ActiveXObject("WScript.Shell");

var oDesktop = oShell.SpecialFolders("Desktop");

var oShortcut = oShell.CreateShortcut(oDesktop + "\\Calc.lnk");

oShortcut.TargetPath = "calc.exe";

oShortcut.Save();

oShell = null;
oDesktop = null;
oShortcut = null;

WScript.Echo("Shortcut Created");

}
catch(e){

WScript.Echo("Error " + e);


}

Type into notepad & save that as link.js

Then ShellExecute the script and you are away.....

To do something similar in VC++

Code:

#include <windows.h>//Essential stuff
#include <objbase.h>//get COM up and running
#include <Shlobj.h>//for interfaces
#include <comdef.h>

inline void TESTIT(HRESULT hRes){
	if(FAILED(hRes))
		throw _com_error(hRes);
}

struct COM_INIT{//setup com
	COM_INIT(){CoInitialize(0);}
	~COM_INIT(){CoUninitialize();}
}COM_INIT_;


int WINAPI WinMain(HINSTANCE hThisInstance,
	   HINSTANCE hPrevInstance,
	   LPSTR lpszArgument,
	   int Show){

	char *lpstrTargetPath = "C:\\WINDOWS\\system32\\calc.exe";

	WCHAR *lpwstrLinkPath = L"C:\\Documents and Settings\\All Users\\Desktop\\CalcLink.lnk";

	try{

		IShellLink* ISL = 0;
		IPersistFile* IPF = 0;

		TESTIT(CoCreateInstance(CLSID_ShellLink, NULL,
			CLSCTX_INPROC_SERVER, IID_IShellLink, (LPVOID *) &ISL));

		TESTIT(ISL->SetPath(lpstrTargetPath));

		TESTIT(ISL->QueryInterface(IID_IPersistFile,(void**)&IPF));
		
		TESTIT(IPF->Save(lpwstrLinkPath, TRUE));

		ISL->Release();
		IPF->Release();

		MessageBox(0,"Success!","",MB_OK);
	}
	catch(_com_error& e){
		MessageBox(0,e.Description().length() ? e.Description() : "COM Error","",MB_OK);
	}

	return 0;
}

I get an error code from CoCreateInstance. Where can i find the spec's for the classes, i.e CLSID_ShellLink?

All the CLSID info and interfaces are defined in Shlobj.h or shobjidl.h....the library you need for that is shell32.lib I think

That code compiles on VC++6 under Windows XP

Thx..
