Urgent Need Help (DLL & MultiThread & Dialogs)

Hello,
Excuse my bad english i m french!

Here's my strange probem :
i m writing a WSock32.dll that should be able to popup dialog when the user goes to forbiden sites
all works fine i create a dialog resource create the dialog with Create(IDD_SHOWINFO)
and then show the message !
i create the dialog in WSAStartup which is called only once at the loading of the dll
so problem is that Iexplore load the dll call the WSASartup once but when i close Iexplore it dont call the WSACleanup, destroy all the windows i created before but doesn't not unload the dll so when i relaunch
Iexplore it calls directly the dll functions but when the dll should popup dialogs it cant because the dialog
doesnt exist anymore!

i decide to check wether the dialog exist and if not to ceate a new one but i makes hang the dialog box!
i think its because Iexplore is multithreaded so it call my function 3 times at once and so i create 3 dialog
so i use mutex and the same things apear

but if i put a AfxMessageBox("") at the end of the creation i can see my dialog and all work fine until i click on the ok the MessageBox!


If somebody has read all the above and can help me it would be really really great!
Thanks in advance

Hello,

I don't know with type of DLL ( MFC ).

But if you use VC 5 or 6 for the 4 i dont remember, you can use appwizard to create a MFC DLL ( shared not static because you may have problemes ).
I do this with the resource located on the dll and i have no probleme.
