    Refresh exporer based displays

    When I programmaticly delete a file on the desktop, the image of it remains there until I manually refresh it. Is there an API or something that will cause all explorer-based displays (like the desktop, explorer, open file dialog boxes, etc.) to refresh?

    Hmm. The FolderView class, which is what Explorer uses, normally opens a directory change notification handle (e.g. FindFirstChangeNotification) for the path that it's looking at, so that the file system driver tells it when something changes.

    Not sure why it wouldn't be tracking your deletion though.

    Well, that happens on a Vista system, so I wouldn't be surprised if that has anything to do with it.
    What ever the cause, I need to manually refresh it somehow.
    Is there a MC WM of some kind I can send the desktop?

    There is an API to refresh the desktop. I know because we used it in our product once. However it rearranges all your icons as well so users may not like it.

    Code:
    #pragma comment( lib, "shell32.lib" ) 
    #include <windows.h>
    #include <shlobj.h>
    
    int main(void)
    {
        SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);
        return 0;
    }
    If a desktop item is properly deleted using the shell api, the desktop will be automatically updated. So, the issue may be with how you delete the file on the desktop
