The SND_ASYNC flag plays the sound without interrupting other threads.
How do you measure that the other threads are interrupted?
In which thread is the PlaySound function being called.
Some info about how the threads are arranged in the application would help for better diagnosis.

I am using SND_ASYNC mainly to achieve that. But it still interrupts other threads. I am playing it in a separate thread that runs parallel to other threads and runs upon receiving an event or else waits indefinitely for the event to occur.
I can tell that playing a sound effects other threads by looking at the frame that I grab continuously from a framegrabber, where I miss a part of the frame whenever I play the sound.
All my threads run parallel and all the threads wait for a certain event to occur. I start all the threads when I run the application, but keep them waiting for certain events to occur. While couple of threads run most of the time, some threads only run when they receive certain event.
thanks

The standard MFC windows provide full scrolling capability. Your code just needs to set the window and view sizes to enable scrolling. Take a look at the CFormView class[^].

What do you mean by "develop window application project in asp.net"? The two are mutually exclusive.

There is no "best" choice, there are merely different solutions. The best one is the one that most closely offers a solution to your requirements: Win32, MFC, Windows Forms, WPF etc., it is up to you to decide which one to go with. However, you seem confused about the difference between desktop apps and web apps, so you should decide first which of those is necessary for you.

Hi All,
I have a compressed AVI file.
Can i use OPENCV to decompress the AVI file and read each frame in it?
OR should i go for a library like FFMPEG?
Can i used FFMPEG functions inside a MFC application to read AVI files?
Please help me in this.
Thanking you in advance.

Hi,
I am having a lot of problems displaying the CFileDialog modal dialog box
after much research I have noticed many examples of the CfileDialog with Just 1 paramter
and then a DoModal e.g. CFileDialog mydialog(TRUE); mydialog.DoModal();
The problem I am encurring is when step to the mydialog.DoModal(); a breakpoint is hit "int 3"
and I get a access exception
has anyone had this problem trying to use a CFileDialog
Thsnks

CFileDialogs are pretty much as simple as it gets... with that said, your question doesn't make a ton of sense. What's error that you're getting exactly? Is it a breakpoint or a assertion that's stopping execution?
Place applicable code and maybe I can get a better idea as to what you're doing wrong.

That exactly the point I had the contructer coded with filers window title etc.
but this code
CFileDialog mydialog(TRUE);
mydialog.DoModal();
should work
This what happens when I step to mydialog.DoModal();
The code hits a break point
and later on get a access violation
doing a Call Stack at this point seems that mscowrks.dll is executing
I moved this code to the beginng of CWinApp::Initinstance
so Its one the first things I do and still I have problem
000007FEFD223C6A nop
000007FEFD223C6B nop
000007FEFD223C6C nop
000007FEFD223C6D nop
000007FEFD223C6E nop
000007FEFD223C6F nop
000007FEFD223C70 xchg ax,ax
000007FEFD223C72 int 3
000007FEFD223C73 ret
000007FEFD223C74 nop
000007FEFD223C75 nop
000007FEFD223C76 nop
000007FEFD223C77 nop
000007FEFD223C78 nop

You're probably compiling this with some odd options, that's part of .Net (I believe), which you shouldn't be using at all on a C++/MFC application. I would guess your problem is not the code but the way you configured the project.

Assuming this is a continuation of your previous problem, I already suggested this[^], and similarly tried to explain, here[^], about the correct use of casts in C. Randomly changing parameters or removing them altogether is no substitute for making full use of both documentation and debug information.

I did that and I still encountred the problem breakpoint followed by access violation
bottom line till me if I right
CFileDialog.mydialog(TRUE);
mydialog.DoModal(TRUE);
Should work as it would take default paramters correct ?

Not necessarily, as we do not know what else your code is doing. As I said before, read the documentation[^] and carefully check against your code. Also ensure that your project has been completely rebuilt to ensure no undiagnosed compiler errors remain.

I'll re-read the doc
but
1) I got s clean build
2) this is the first thing in CWinApp::InitInstance
thank you

There must be something wrong with your system that we are not aware of. Does this application run correctly if you do not use the CFileDialog?
Use the best guess

|

Yes it does
I am begining to think it must be something like file permissions
I live next to someone who worked for MicroSoft
He had a look at it once I'll ask him again
