I have a really strange problem with VC 6.0.
At a place in my program I start 2 new threads ( GUI and Worker ) and if I put a break points in the worker thread and then when the program comes to the break point and should break, Everything locks up for 20-60sec.
VC totally freezes and all other applications on my machines is also effected
(Can’t close them, no redraw. But if IE is showing an animated GIF this is still running, and mouse pointer is working so it’s not a total lockup and task manager is NOT showing any process running at 99-100%)
This lockup ONLY happens when I debug in my worker thread.
If I don’t put any break points in that thread everything works as it should.
And it’s really annoying. And I tried removing the ncb/opt files, reinstalled VC , close everything else running But nothing helps. If anyone have and idea of what it might be please tell be before I’m going nuts and throws the computer out the window.
I’m running VC 6.0 SP5 on Windows XP SP1 .

I see a problem like this from time to time, where VC++ appears to hang when a breakpoint is reached in my multithreaded app. The only workaround that I've found that sometimes works is Ctr+Alt+Del to bring up Task Manager, which wakes VC up again.

Hi ,
Does anybody know how to read a dump file ?
I mean that I would like to know the functions names not thier address ?
Is it possible?
Do I need another program to do this ?
Thanks

You can read dump files with Visual Studio.NET or with WinDbg (from the Microsoft Debugging Tools[^]).
You'll need the debugging symbols for your application, for the system, and for any third-party DLLs you're using, to get the best out of a dump file.

Hi,
I want to play a wav. file and at the same time stream the samplple values (raw data) in real time into a vector or something in order to do signal processing on the samples.
I guess that the sound file contains some control bits (for instance sample frequency, rate, etc.), but I´m only intested in the actual sound data.
Right now I´m using PlaySound() to play the wav. file, but I cant manage to extract the actual sample values...
Thanks in advance!
|
|
|
|
|
lol, this is very easy!
read the sample rate and the bits per sample out of the wav file, then read a block, perform DSP action on the samples, copy it into a sound buffer, start playing, and continue with the next block!
Don't try it, just do it! 
|

Thanks for the help, but it doesn´t quite solve my problem.
The thing is that the wav-file really is a simulation of a real time situation of someone who speaks in a microphone. Therefore I dont have access to the whole file, i.e. I´m not suppoed to know what comes next. Therefore, it would be better if the sound (or the sample values), while it is playing, is streamed into a buffer which length increases during the file.
Do you know how to do this?
Thanks a lot!

capture an incoming packet, perform volume scan on it, and write it to a playing sound buffer!
it's like streaming with a very small buffer!
Don't try it, just do it!

Hi i was wondering if there was a way like with a list box to add an ItemDataPtr i look at the functions its got and it doesnt have this as a member function is there another way that it can be done? i have a situation where i am using lots of different classes and need to be able to retrieve them through the tree

You can use SetItemData(). Just cast the pointer to a DWORD and it will work fine, unless you're compiling for 64-bit Windows (which you probably aren't  )

You can use SetItemData() to setup poiters to the objects,
or indexes in polymorphyc collection that contained these
classes.

I would like my NT service to transparently display dynamic text on the desktop. Preferrably with GDI+, Windows XP. Any cool ideas? 
Regards,

Method 1: Enable Active Desktop and set the Windows background to an HTML file.
Method 2: Write text to a bitmap and set that bitmap to be the desktop background.

Create a Window and modify it's region with the written text.
Here you can find a great sample of a trasparent application:
http://www.codeproject.com/miscctrl/transclock1.asp
It's the same tecnique that somebody uses to make skin dialog/windows. So you can look at other sample too.
To simulate it on the desktop, you can change the Z-Order with the SetWindowPos, so all the other windows will be above it.

Sorry, I didn't read that your was an NT service...
In that case, to keep my idea, you need a small "client" app that dialogs with the service...

This technique seems to suit me! Thank you very much.

SHFILEINFO shInfo;
m_imgList.Detach();
m_imgList.Attach((HIMAGELIST)SHGetFileInfo("C:\\", 0, &shInfo, sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON));
m_imgList.SetBkColor(ILD_TRANSPARENT);
SetImageList(&m_imgList, LVSIL_SMALL);
What the hell is wrong with the above code???
It's weird, cuz when I index image 0-5 they appear...but nothing beyond that???

Hi All!
How can i get the activity on speaker/mic so that i can build the activity meter within my aplication. My application allows voice conversation between two parties. I want to display speaker & mic activity meter on my application. Any sample or piece of code will be highly appreciated.
Thanks a lot

read a raw sound block coming from the mic(they have to be quite small), then initialize 2 variables called "iMin" and "iMax"(both initialized with the null sample values), setup a loop for every sample, and then check if the sample is bigger then iMax or lower than iMin and correct the variable then.
after the block, you know, that the average volume is!
show a scale from 0 till sizeof(bytespersample) and show ( iMax - iMin ) there.
Don't try it, just do it!

Hi!
Thnaks for the solution, but i am just a newbie and have no idea where and how to read mic/speaker buffer? If you can tell me some APIs or any example coz i have no idea of sound APIs and data structure, that will be really helpful.

Where can I find information about the various sizes of integers among the various compilers and CPUs. By size I mean how many bytes an integer object is.
|
|
|
|
|
Usually compiler manuals will tell you. I would think that most languages integers will be 32 bits.

use sizeof(int) on every compiler you wan't to know the size of

In an overloaded "<<" routine, I created an array on the heap. Then I used it to do what I needed, and just prior to the "return" statement, I deleted the same array. However, doing so causes the program to crash when I run it.
Interestingly, if I were to remove the "delete[]" statement, the program runs fine; it doesn't crash, but put it back in, and the program crashes.
The whole idea of using the "delete[]" statement on an array created on the heap, is to avoid memory leak. Here, it makes the program crash.
Does anybody have any idea why? Thanks!
