Thanks for the link, very interesting but I think I'll stick with pointers for now.

Hi Dan, just a wild guess: maybe Vista is by mistake taking the same icon for all files in a particular folder; try creating a new folder and moving some of the files in there. :) Luc Pattyn [Forum Guidelines] [My Articles] - before you ask a question here, search CodeProject, then Google - the quality and detail of your question reflects on the effectiveness of the help you are likely to get - use the code block button (PRE tags) to preserve formatting when showing multi-line code snippets

Two UI threads in 1 app maybe? xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - out now! ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

There's lots of info and some sample code here: Tab Controls[^] Mark Salsbery Microsoft MVP - Visual C++ :java:

If the file is opened within a thread you control, then perhaps you could set something up to track which files you have open. Then you could just check against the tracker. Perhaps this tracker could also fire events so that other threads wouldn't have to keep checking to see if the file is available. Maybe even a waiting list so you can see how many threads are waiting to open a file, you could even prioritize the list.... the possibilities are endless. But err, maybe just a list of files you have open. My current favourite word is: I'm starting to run out of fav. words! -SK Genius Game Programming articles start -here[^]-

Do you really need to copy the list? Why not something like this: void IWantAList(LPARAM lp) { using namespace std;   list<string> *pList = reinterpret_cast<list<string>*>(lp);   // Use pList... }   void SendList() { using namespace std;   list<string> list;   // ... //   IWantAList(reinterpret_cast<LPARAM>(&list)); } Steve

Thanks for the reply, I have tried adding the manifest as specified but it makes no difference. I have also defined SIDEBYSIDE_COMMONCONTROLS in my stdafx.h and called InitCommonControls() in my constructor all with no success. I read somewhere that I needed to set the resource ID to ISOLATIONAWARE_MANIFEST_RESOURCE_ID but that stops my DLL from registering. The only part of the "Using XP Visual Styles" I am not sure about it whether I am using the correct SDK. I have installed "Microsoft Platform SDK for Windows XP SP2" and specified the include and lib directories in the project. Is that all that is required to use the SDK or are there more steps I need to take?

I answered my own question, CopyIcon does the trick!

This won't solve your marshaling problem, but: You can't use strcpy, or TCHAR. All your strings are wchar_t in C# so you should be using only wide character functions and types. Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Also, this may help: CreateGrayscaleIcon[^] The use of GetPixel() and SetPixel() are way slower than accessing pixel data directly as I proposed in my previous post, if that's an issue. Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

I don't know if there's a way to tell windows to postpone shutdown (perhaps there's a registry key for this), but right now I see only 2 alternatives: 1) Cancel the shutdown while your shutdown process is still running or 2) Start the shutdown process in a separate thread and don't cancel windows shutdown. But then your shutdown process can be aborted unexpectedly, so this might not be a good idea (depending on the real use case). Regards, mav -- Black holes are the places where God divided by 0...
