go in solution explorer and you will find Reference and click right on Reference and choose Add Reference and after that you can choose your reference

You're getting this error message because your trying to add a reference to a .DLL that is not COM-based, just like the message says.
In order to use the functions in that .DLL, you do NOT add a reference to it. You call the functions through P/Invoke. Define the function headers in your code using the Declare statement and setting up the arguments that the function is expecting. For example, to call the Win32 Beep function found in kernel32.dll:
Declare Function Beep Lib "kernel32.dll" (ByVal frequency As Integer, ByVal duration As Integer) As Boolean
Then later in your code:
Dim r As Boolean
' Make a sound at 4000Hz, for 250 millisecond (1/4 second)
r = Beep(4000, 250)

First of all, txt speak just makes you look like an idiot
Second of all, we're here to help people trying to program. People who say 'I don't know anything, so tell me from scratch how to do these tasks', don't get much help.
Third, VB6 is a dead language, and a terrible one. Microsoft withdrew all support some time ago, why would you learn this intead of VB.NET ?

I am trying to help, seriously. Your question is just annoying, because of how you typed it. others will tell you the same, or just ignore you. We're not 12 years old here.
And, VB6 *is* a dead language. Why are you learning it ? I suspect it's a class, in which case, you really need to do your own homework.

According to your other posts you are a student wanting to learn. So why do you want us to do if for you from scratch? Most of us learned by trying and trying again. If you want to learn, look at online tutorials or buy a book.

Hi
I wonder if any kind person out there may be able to help me.
I am writing an ocx (vb6), in which it is necessary to watch for directory and file changes.
Ths is done by creating a new thread and then using ReadDirectoryChangesW and WaitForSingleObject to do the watching. This works perfectly, but when the calling .exe shuts down, I have to be able to destroy this thread, and that is where the trouble starts.
Once this new thread is started if I attempt to shut down the calling application, the ocx does not terminate. Although it is sent a WM_NCDESTROY message by the caller, VB seems to intercept this and it never arrives at the ocx's window proc. The ocx's terminate event is not called either and the caller continues to run (albeit without a window). If I use the End directive in the IDE, VB crashes, and if I run it as a compiled exe, it does not terminate.
Does anyone know if it is possible to detect that the calling app wants to shut down so that I can destroy the extra thread created by the ocx and allow a normal shut-down to take place.
Any help would be appreciated as I am horribly baffled.

You may use the WaitForMultipleObjects [^] function (instead of WaitForSingleObject one) to wait also for an event and then raise such event whenever you need to terminate gracefully your thread.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi Pallini
Thanks for your reply. Your suggestion is certainly a far more elegent way to end the thread, but unfortunately I cannot detect when parent of the ocx is about to shut down, as for some reason it does not call the terminate event

Dear Sir/Maam,
I'm using visual basic 6 (NOT .net) to capture the screen (Screenshot) of a certain application window (Say, cmd.exe).
I already know how to capture the ACTIVE WINDOW. Is it possible to capture (Screenshot) an external proccess (cmd.exe) that is not the current ACTIVE WINDOW?
Please point me to the right direction.
Thank You.
PS: I did search codeproject for a possible article, all articles were all for VB.NET.

It's done using the exact same process. All you need is the window handle.
BUT!! (there's always one of these  ) You can only capture what you see on the screen. If the window is not visible at all, you won't see anything in your captured image at all either.
