A Google search for "XModem class for Visual C++" works well for me.

Is there any API in VC++, that when called by the main thread, the main thread should wait until all the threads created by this main thread exit.

Have you looked at WaitForSingleObject() and related functions?

|
|

WaitForMultipleObjects()

Hello, Sir:
I have a touble with CPU test. And I am working CPU Test. That test item have MCA ID Test, Numeric Coprocessor Test and FPU Test. Because I know a little about those. Can somepople help me? Maybe you have some about those. Can you help me? Or you can tell me some article about those? Thank in advance.

Use the CPUID assembler command to get the CPU features. Then:

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

They both write a byte 0xAD to the port 0x64

Hello, Sir:
Thanks your reply. Now i have some about that. But i have some trouble with the FPU. I have studyed IA-32 Intel® Architecture Software Developer’s Manual, and knew some about FPU. I need test CPU FPU function, it include "FPU Exception Test", "FPU Control Register Test", "FPU Tag word Register Test" and "FPU Calculation Test". And I don't how can test those really. Do you know how to "test" such FPU fuction. Do you have a example about those, or give me some advice? I am helpless, waiting...

Sorry, I don't know.

Hello,
I'm developing a program that does some intensive computation(arithmetic coding) on a block of data, say 2MB in size. It tooks longer time to finish. If I implement the same computation using 2 threads and split the input into two equal halves(1MB), one for each thread, does the computation time decrease? please help me.
Is there any way to speed up the computation using threads?
I have only one processor, P4 1.7 GHz non HT. I'm using windows 2000.
The computation is directly proportional to the size of data(i.e if it took 5 seconds for 3MB input, then it will take 10 seconds for 6MB input data).
regards
Ramesh

No, on a single-processor system, the context switching overhead will most likely hurt your performance, not improve it. However, being able to split the data and parallelize the process as an option is a nice feature for those who do have multi-processor systems.

On a single processor it would, if anything, be a little slower because the OS has to switch between threads (though not noticably). If the intensive computation is affecting things like clicking a button in the app, and general app response time then it would be worth sticking the whole process in its own thread and let the apps own thread just deal with message processing, thats probably the best solution (in effect there would be two threads anyway, one for your exe thats instantiated upon load, and the other is your 'worker' thread).

Hi everyone
When I use Visual C++ 6 to build a Doc/View application the final application will have an icon it its title bar. This icon is 16 x 16 pixel and looks exactly as the corresponding 16 x 16 pixel version of the icon I can edit in the resource editor.
On the other side when I build a dialog based application it will have an icon in its title bar, too, it is 16 x 16 pixel in size, too, but it does not look the same as the icon I can edit in the resource editor. I guess it is "shrunken" from the 32 x 32 pixel version of the icon in the resource editor, nevertheless it is not what I want because this "shrunken" icon looks distorted.
A screenshot demonstrating this behaviour:

Can anbody explain me the reason for this and how to prevent it?
Thanks,
Matthias "T.T.H." Grobe

I'm guessing here, but its probably a subtle change microsoft made to distinguish MFC dialogs from MFC apps. You could just use the dialog editor to copy the icon you want and paste it into the dialog project? Hope this helps.

It may be the 16x16 vs. 32x32 thing that's ailing you.

This is because CWinApp::LoadIcon will only load the large 32 x 32 pixel icon, and when you call CWnd::SetIcon(m_hIcon, FALSE), the SetIcon() function will shrink the 32 x 32 icon to 16 x 16. The fix is to add another icon member to your dialog class to hold the small icon, use LoadImage() to load it, and set that as your small icon
class CMyDialog : public CDialog
{
protected:
HICON m_hIcon;
HICON m_hSmallIcon;
...
};
CMyDialog::CMyDialog(...
{
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
m_hSmallIcon = (HICON)LoadImage(AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDR_MAINFRAME),
IMAGE_ICON,
16, 16,
LR_DEFAULTCOLOR);
...
}
BOOL CMyDialog::OnInitDialog()
{
...
SetIcon(m_hIcon, TRUE);
SetIcon(m_hSmallIcon, FALSE);
...
}

Have a look at the ExitProcess Windows API function.
Hope that helps

Here is inserted block:
exit, _exit
Terminate the calling process after cleanup (exit) or immediately (_exit).
void exit( int status );
void _exit( int status );
Function Required Header Compatibility
exit <process.h> or <stdlib.h> ANSI, Win 95, Win NT
_exit <process.h> or <stdlib.h> Win 95, Win NT
PS. But it's better to close and clear your program and exit.
