Anyone know the reason why the WS_MAXIMIZE style bit isn't taking effect when I don't also specify the WS_POPUP for the window's style? MSDN doesn't suggest it's ignored, although a quick Google leads me to believe it could be for overlapped windows.
I need to initially maximize a window during the app startup. I've always used ShowWindow() in the past when maximizing a window without much headache, but now I need to control the order in which this happens moreso to avoid unsightly drawing issues as I need to perform quite a few tasks during the startup (working on my first 3D game). As such, I'd rather have it maximized before the window is shown rather than after and don't want to go through the trouble of screwing around with the message queue to deal with it.
Surely there must be a simple way for an overlapped window?
TIA

That doesn't work either (just tested, it's still ignored), unless I use it after the window has been shown, which means I still get the flickering during startup.
[edit] Ok, I made a couple changes with the queue and got it to maximize, but I still get the drawing issues that I do with ShowWindow(). Now, pardon me while I beat my head against the wall.  [/edit]
Thanks for the reply though.

I got rid of the flicker by adding a couple of painting ops (hope it doesn't mess me up down the read as I'm new to OGL).
But, if anyone knows why CreateWindow() doesn't honor WS_MAXMIMIZE for anything but a popup, you'd be my new hero for the day. Either way, thanks for watching me whine.

How is ShowWindow() called? In most applications, ShowWindow() is called *after* you've called CreateWindow(), hence making your window seemingly ignore your flags. In MFC apps, what's passed to the mainwindow's ShowWindow(), is whatever the process has been fed (settings on shortcut, spawning process, etc).

You don't need to fiddle with WS_MAXIMIZE. Just create the window without the WS_VISIBLE flag. Then call ShowWindow() with SW_SHOWMAXIMIZED. No screwing around with the message queue.

It has to be, otherwise I wouldn't have a valid handle.

Did that. In fact I rarely use that bit for a main window.

Did that, except I used SW_MAXIMIZE instead.

Not always. At first, doing what you just described, it was showing the window, then showed it maximized, and then drawing the OGL scene. There's a small delay during startup because of the processing involved, but it was a three part startup that I could actually watch happen.
So, I thought, why just use the bit in CreatWindow() itself except that didn't work. Hence my post.
Anyway, I got around it by messing with my drawing code, but I would still like to know why in tarnation that style bit didn't work for CreateWindow.

Oh, and thanks for the reply. It's the end of the day and I'm getting slow.

If you are missing knowing how C++ .h and .cpp files and class/function declarations and definitions work then yes, you are missing something.

it may be best for you to read some books and go through some tutorials instead of getting a quick answer to your problem - this is really fundamental so you should learn the basics before going on with your task

Yes. You need to declare class members when creating the class. I would suggest you search around for a few tutorials on the web to help get you up to speed on this.
If you perfer books, then there are quite a few excellent MFC books out there I can recommend as well.

I have an application where I want to be able to receive data from a socket at any time and at the same time be able to send data. Is it ligitimate to issue a send()in the main thread while I am blocked on a recv() on the same connection in a different thread?

Yes, dependent on the protocol and implementation of the remote process.
|
|
|
|

Your answer is somewhat obscure. The protocol is TCP/IP. I don't know what significance the remote process has, assuming that the remote process you are referring to is what is on the other side of the connection. Assume for now it is the same configuration on both sides of the connection.

That is the transmission protocol. I am referring to the application protocol.

"may have no relationship" How do you know? There must be a protocol that indicates this correct?Last modified: Thursday, June 29, 2006 10:36:53 AM -- sorry hit the post button before I finished (ooops)

As long as the data isn't interdependent on one another there is no technical issue I'm aware of that says this isn't a problem. If it is, then you should avoid this and/or use semaphores, etc. and marshalling to help keep the data in check.
To use an analogy, you don't want to receive a answer before you send off a question for the answer first.
So, if the data isn't dependent you should be ok, all normal issues like bandwidth, remote connections capped, etc. notwithstanding.

Your analogy is correct for a transfer model of question/answer, but in this case, the data coming from one direction may have no relationship to the data going in the opposite direction.
Take for example an implementation of a TCP/IP terminal program where the user types on the screen some information that gets sent over the socket, but the other side at any time, could be sending information to be displayed on the screen unrelated to the information being typed by the user.
I assume your use of the word "dependent" means the answer to the question previously sent. Again, that is not the model used.
Thanks for your feedback. It is appreciated!

Yup. Then you should be ok if that's the case.

Yes, it's legitimate. Send and receive buffers are separated, so threading isn't an issue for the IP-stack.

Hi All,
I have a list control in report view with slider controls as items.
When I scroll through the list using the mouse wheel or page up and page down, some of the track bars in the slider controls get changed.
Can anyone help me with this problem? I tried using a progress bar but I get the same problem.
