I am trying to write a plugin, but I am having this warning come up 'CoInitialize has not ben called'. I have no idea after a lot of looking round what i am doing wrong or what this warning means. Any help most welcome. I am sure it's something silly I am doing. I think it has something to do with me trying to read a XML file into my plugin.

If you're calling the MS XML interface, you need to call CoInitialize() before you call MS.

However, I would recommend using XML-SCAN instead, which is part of my nuxporter plug-in. It's a lot less overhead, and faster. Also, if you start with the nuxporter project as template, you already get access to the DeleD scene, because it does the parsing for you.

Thanks for reply jwatte. Unfortunatly i am using Turbo Delphi and i am trying to make a importer so i cannot make use of your code as C++ eludes me at the moment. I am using MS XML and i can not find anything about coinitialize in borlands help. I am quiet new to delphi programming so i am no doubt missing it .

You can have a look at http://destructor.de/xmlparser/index.htm , it's a XML parser which I use for my plugins.

Turbo Delphi most certainly supports coinitialize, it is part of the Windows 32 API. The reason why you cannot find it in the help is that the standard Delphi help does not contain the Win32 help, it's a separate helpfile with the older Delphi's, not sure about Turbo Delphi. Also, older Delphi's did suport Win32 context-help (i.e. type coinitialize in the IDE, put cursor in it, hit F1)... but again, the latest Delphi helpsystem might not support that (it is not as convenient as it used to be back in the good old .hlp days).

Anyway, back ontopic: To use coinitialize, use the unit ActiveX (or Ole2 if you are 'oldschool'). Every thread in your application should coinitialize( nil ) and couninitialize. Inside a .EXE, the Delphi RTL takes care of this, but inside a DLL (or if you use multiple threads), you have to do it yourself.

Hope that helps. Using a non-COM XML parser, like Mr Fletcher suggests, will also solve your problem... but knowing how coinitialize works is useful anyway!

Thanks Mr.Fletcher But I don't seam to be able to get this to work in turbo as it wont allow 3rd party Packages.

Thanks Paul_Jan i think i understand now. will give it a go fingers crossed.

You can just use the units, you don't need to install it as packages. Just put them in a directory where the compiler finds them and ad LibXML (or how the unit is called) to the uses section.
