Ok, makes sense, thanks. Now I understand what I fixed. However the windows headers don't have a really good place or uniform way to declare either, so I can't do a bit of grepping and isolate all clsids. However I found a big batch (160 of them) in the comdef header, with among them the correct value of clsid_shelllink (so I know they are really clsids). These are already committed, and I'll try to get it in 2.2.2.

The COM obects creation routines ( CoCreateObject and friends ) expect a classid to locate the implementation object to instanciate. Hope this help.

I suspect it is in the classid. (the clsid_ constant). Apparantly when I converted the headers, I thought there only was one ID. However it seems that classids, and the ids in interfaces are different. I don't know enough from com to understand the difference, but when I copied and pasted a value for clsid_ishelllink found on the web, the example worked, with or without coinit*.\ So the value in the FPC headers is wrong, and the IID values in the headers. So I grepped the SDK headers, and the shellink clsid is: DEFINE_SHLGUID(CLSID_ShellLink, 0x00021401L, 0, 0); // 00021401---C000-0046 while the iid starts with 000214EE ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Thanks, but it didn't solve it. The same code (+coinitialize) works in Delphi 5. Maybe it's the dispinterfaces problem in fpc?

[fpc-pascal] EOLESysError calling CreateOLEObject
Hello,
I created a very simple program to create a shortcut in the desktop,
but it crashes with EOLESysError (nothing else in the error message).
I tryed to google, but it didn't show much. Am I missing some kind of
initialization call that should be made? thanks, here is the full
program.
{ Creates a link to the Windows calculator in the desktop }
program createshortcut;
{$ifdef fpc}{$mode delphi}{$endif}
uses SysUtils, Windows, ShlObj, ActiveX, ComObj;
var
IObject: IUnknown;
ISLink: IShellLink;
IPFile: IPersistFile;
PIDL: PItemIDList;
InFolder: array[0..MAX_PATH] of Char;
TargetName: String;
LinkName: WideString;
begin
TargetName := 'c:\windows\calc.exe';
{ Creates an instance of IShellLink }
IObject := CreateComObject(CLSID_ShellLink); // Crash here
ISLink := IObject as IShellLink;
IPFile := IObject as IPersistFile;
ISLink.SetPath(pChar(TargetName)) ;
ISLink.SetWorkingDirectory(pChar(ExtractFilePath(TargetName))) ;
{ Get the desktop location }
SHGetSpecialFolderLocation(0, CSIDL_DESKTOPDIRECTORY, PIDL) ;
SHGetPathFromIDList(PIDL, InFolder) ;
LinkName := InFolder + PathDelim + 'Link created with Free Pascal.lnk';
{ Create the link }
IPFile.Save(PWChar(LinkName), false);
end.
