OK. I will start looking into it. If you think of something particular, please let me know.
Thanks a lot !

Do you have any paint on your dialog?
|
|
|
|
|
Theres a OnPaint function in the dialog class (see code in answer above). But putting calls like m_chekbox.RedrawWindow(),
m_chekbox.UpdateWindow(),
m_chekbox.Invalidate()
etc. does not solve the problem.

Hello everyone,
I was just wondering if it is possible to build a Window Application which can monitor a Third-Party software's activities?
What I mean by that is to be able to know which Button is clicked in a certain 3rd-party application. Let's say you have your "MS words" open and you are working on a document. Once you click on buttons like, Bolld, Italic, Save As, Save, Print etc..., your window application can tell you specificly what action was requested?
These are Learing question and please feel free to share with me your suggestions.
Thank you very much for your time.

Yes - look into Windows Hooks. Specifically, I think a CBT hook can help you with things like this.
Trivia: MFC (in VC++ 6.0 at least) uses CBT hooks internally for certain functionality.
Peace!

If you've got visual studio installed, try launching Spy++ (in VS's tools menu) - that'll show you all the windows messages an application is receiving, which can tell you which buttons, menus, etc are being clicked

I am writing a program where I want a sound file to play while I update the main window. I have everything implemented with the sndPlaySound() function, but when the program runs, it becomes unresponsive as long as the sound clip is running. That is, if the user tries to move the window, the whole thing goes white until the function that is updating the window is finished as well as the sound has stopped playing.
I implemented a second thread to try to do nothing but call the sndPlaySound function, but that did not work either. It played the sound, but the window still goes unresponsive if anything interrupts in my functions.
Does anyone have ideas on how to do this properly?
I have searched through the multi-threaded posts, but haven't found anything so far.
Please help, if possible. Or point me in another direction on how to implement this properly.
Thanks.

You can use the SND_ASYNC flag... Look up the documentation for the PlaySound(...) function.
Peace!

I am already using the SND_ASYNC flag on sndPlaySound function.
It seems that the drawing of the window doesn't happen once the user clicks anything in the window.
|
|
|
|

Are you using any other flags? You might not be combining them correctly. I have used the SND_ASYNC flag lots of time and never had it stall anything like you are describing.
You do not have any code that is waiting for the sound to finish, do you?
Peace!

No, I am not using any other flags in the sndPlaySound function. That seems to be working. What i am having a problem with (now that I look at it further), is in my ability to update the window as I need to. I am using a simple 'wait until X amount of time has passed', then I update some values, call Invalidate(); followed by a UpdateWindow().
This all works unless, in the middle of my function where I am drawing the window, the user clicks my window. Then, it doesn't update until the very end of the function and I am not sure why.
I originally thought that maybe having the sound play on another thread would help, but it isn't.

If your "wait until X amount of time has passed" implementation is a blocking one, like calling Sleep(...) or going into a spin, you will not be able to pump any messages, so you will not get the Paint message to update the screen.
For example, if you are trying to do some cheap animation using old-school-style techniques in a loop, it will not work the same under Windows.
If you are doing the above, you can change your wait to use a Timer message, and then when the timer message fires, you can do your updates.
Peace!

Thank you for the help. Can you point me in the direction of Timer message info? I have never heard of this before.
Thanks again.

Look up the WM_TIMER message and the SetTimer(...) function. If you need high-accuracy timers, look up multimedia timers.

Okay, so I'm going through some code (off codeproject), which is always interesting, since you see so many different styles. One piece of code had a class within a class, I suppose forcing only one user of the internal class. I don't even know if I'm using the correct terminology, so bear with me.
I come from the school of development where one .cpp and one .h file defines one class. I've seen others have a utility.cpp/h file with multiple classes in it. In the past, this arrangement made it difficult to find things, but I suppose with the advent of code browsers, the issue is more subdued. However, in keeping with the one class / one file appproach, I tend to code my applications centered around dialogs or views or etc... standard mfc stuff. I doubt I'm the only one.
So, in real application development, some of these dialog/view classes can get huge. Due to the nature of my application, I am heavily dialog centric, so most of my application classes inherit from CDialog, etc. The data and processing associated with this dialog processing is heavily coupled to the dialog and usually is not used outside of the dialog. There are some obvious exceptions, and these go off into their own classes. Which brings me to my point....
Some of my dialog classes are large. Managing the data within it would lend itself to a class unto itself for the simple reason of enforcing discipline - the code can easily degrade to spaghetti land. But, I really don't want to break out the data (I guess we're talking business objects in a very distorted way) in a class, viewable across the project, when this class is only going to be used within another class.
How do you deal with this design issue? Inquiring minds want to know
Thanks
