When I enumerate all my network printers, I also get the Acrobat Distiller, and Microsoft Fax. Is there any way of telling the difference between actual hardware printers, and software versions? Thanks.

Hi,
I've seen others putting in a sleep statment after a call to CreateThread(). They claim that you need to wait while the thread starts. This sort of makes sense but I can't find anything to confirm this in MSDN. I was wondering what you guys have to say on this subject. Here is what I've seen others do:
thread->CreateThread();
Sleep(750);
thread->PostThreadMessage(UWM_MY_MSG, 0, (LPARAM)info);
Do you need the Sleep statment? In my program it seems to work w/o it but i don't want it to crash when its released. 750 seems like a long time to wait if do have to wait. what is the shortest time you should wait (if you do)?

I dont think you need the Sleep in between unless you are doing some UI stuff. If so you'd prolly wanna make sure that the window is created and on screen before trying to do fancy stuff on it. But even for that using Sleep is a stupid approach. You can set some kinda event or some other such sync object that you can WaitForSingleObject on

As a rule of thumb, I would use an event object to signal the thread creation at start of ThreadProc, remove the Sleep and use a WaitForSingleObject.
750 ms is too much time to spend in some ocasions. But, if the machine is at 100% CPU, with lots of processes running in a slow machine, it may not be sufficient.

Use waitforsingleobject or with the threadID you can Know the status of the Thread, of is is running or not....
But if CreateThread returns valid Handle is because the Thread was created....

Carlos' comment is the way I'd approach it as well - if it returns a valid handle the thread is up and you can post the thread message. Sleep is an extremely bad idea because it's arbitrary timing that leaves you wide open to race conditions in multithreaded apps (and debugging race conditions is less fun than you ever want to have).
If you want to wait until other processing takes place in your thread proc before you post the thread message, then you can use the other technique suggested here of setting an event in the thread proc when you're ready, and using a call of WaitForSingleObject() after your call to CreateThread().

The handle isn't signaled until the thread is terminated, not started.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Absolutely. I probably didn't word things properly - I had meant that, as Carlos mentioned, that if beginthread returned a valid handle (instead of 0) then the thread proc had started, not that you should block on the handle. In the second example I meant to indicate that you signalled an event in the thread proc (that you created via CreateEvent(), etc.) and blocked on this after creating the thread if you wanted more control.

I've never used this command before, so iI may be completely wrong but there is an AddPrinter command. Look for it on MSDN. Perhaps this is what you're looking for?

Use the function
HANDLE AddPrinter(
LPTSTR pName,
DWORD Level,
LPBYTE pPrinter
);

So. Like I was saying, the powers that be took away my precious, precious ClassWizard. It used to be quite easy to add an OnInitDialog to my About box, just by going to the message map in the ClassWizard and adding a functino for the predefined OnInitDialog.
What are the steps to take to add one now, with the VC7 MDE?

In vc7, there's no class wizard !!! Vc7 manage classes, files... by properties. To handle message, override method, virtual method, simple right click in your classes then select properties. the properties dialog should appear and then you can select message tab, attribute tab, or method tab and select what you need !!!
Hope this helpful !!
Good luck !

I haven't moved to VC7 yet, and I've heard a lot of noise about no class wizard, but from what you're saying, it sounds like we didn't lose any functionality in this regard - they just moved it to a different UI.
Would this be a correct statement?

Hmm. Yes and now. There are wizards for most things like creating classes and projects. Creating methods or event handlers however, is much easier without the wizard interface and a welcome change.

I have been trying to debug my ISAPI extensions on Windows XP pro. But i cant get it work. When I try to use a method from a book it gives me error you dont have required previliges on Internet Explorer but if i use extension without debugging it works fine. Also I cannot get the attach to process method t odebug. Can someone help me out what is wrong. Attach to process just closes my project and opens inetinfo.opt. Can someone guide me step by step.

How do you make to use a CListCtrlEx (my CListCtrl) with GetListCtrl into CListView?
|
|
|
|
|
Something along m_yourListCtrlEx.SubclassWindow(GetListCtrl.Detach()) might work. Not 100% sure, though.

i need to remove some buttons and to change some others from the predefined of a propertysheet mfc dialog.
it's possible by hooking somehow, but i think that it should exist an easyer way to accomplish this.
need some advice.

In CYourPropertySheet::OnInitDialog, GetDlgItem(IDOK) will give you a CWnd * you can use to manipulate the "Accept" button in any manner you please (similarly for IDCANCEL).
