Hi Alok
[[[[[[[[[[[[[[[[[ HELP ME AGAIN ]]]]]]]]]]]]]]]]]]]]]]
I have a worker thread created using AfxStartThread() function. This thread is reading data from a flat file and writing the data to USB. PLAY, PAUSE, STOP, everything works fine without any negative interference on the thread. But while the thread is running, if I minimize any windows, shut down the system monitor, maximise any minimised applications, the thread is affected. The windows I am tampering with is not the one which created the thread. But still, it is giving this head ache.
Please help me with a solution to avoid this.

If you post the code it will be easier to say where the problem is.

Hi Giorgi
The code is very big and contains confidential data. Even if I sent the code through the net, I don't think you will be able to go through the code in one or two days and give me a result. The project contains more than 150 source files each with around 10K lines of code. I hope you got it.

You'd think it'd be really easy but it ain't

Dear all,
I have a question about these functions. According to MSDN, "The WriteFileEx function ignores the OVERLAPPED structure's hEvent member...WriteFileEx signals completion of its writing operation by calling, or queuing a call to, the completion routine pointed to by lpCompletionRoutine, so it does not need an event handle"
To wait for its completion, I use WaitForSingleObjectEx. Because WriteFileEx doesn't need an event handle, what handle should I use to transfer to WaitForSingleObjectEx?
Thanks.
|
|
|
|
|
This doesn't work.
If you use async APIs, then why use WaitForSingleObjectEx to make it sync?
Better use WriteFile without OVERLAPPED structure.
Don't try it, just do it! 
|
|
|
|
|
Actually, I called WriteFileEx and do other tasks while IO task is being performed. Before doing new writing task I call WaitForSingleObjectEx to determine if the previous writing task completed. But I'm not sure how to transfer a handle to the first param of WaitForSingleObjectEx.
Thanks.

WriteFile does exactly that you want to program yourself!
Using asynchron APIs does only make sense if you want the CALLING THREAD to do some other work while the read process is pending!
By the way, there is no reason to call WriteFileEx every time a write operation was completed.
You can also call WriteFileEx many times at the same time, the system queues the data and tells you when the complete process is complete. There is no event handle when you use WriteFileEx.
After a write operation is complete the OS will call the completion routine you set as parameter of WriteFileEx. So the only way to use a wait function is to create an event yourself and set it within the completion routine.
Don't try it, just do it!
|
|
|
|
|
So, I don't need to wait for the previous writing task completes before calling a new WriteFileEx.
Am I misunderstanding you?
Thank you so much for your precious help.
|

You can call the ssynchronous WriteFileEx multiple times while IO is pending.
What the documentation is trying to conveysay is that the completion CALLBACK will be activated not the event handle. So you need to decode which IO request(s) completed when our IO completion procedure is called with the information you originally provided as part of the IO completion callback setup prior to making the WriteFileEx call.

I was wondering how to change the look (or even behaviour) of a windows common control so it will reflect throughout the entire platform. For example I'd like to change the progress control to be a fluent bar instead of the normal block-ish one. I found an article on MSDN about this but it was for Win CE, couldn't find anything for 2K/XP. Does anyone have an idea as where to start?

When run I get assertation failure.
What cause it. I remind it is those global variable defining the main thread.
//////////////////////////////
CWinApp::CWinApp(LPCTSTR lpszAppName)
{
if (lpszAppName != NULL)
m_pszAppName = _tcsdup(lpszAppName);
else
m_pszAppName = NULL;
// initialize CWinThread state
AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
AFX_MODULE_THREAD_STATE* pThreadState = pModuleState->m_thread;
ASSERT(AfxGetThread() == NULL);

Hello,
What assertion do you get and what do the comments say about it?
A assertion in the MFC library usually means that you are doing something wrong!

does anyone know how to get an object moving along the path of a sine wave? I've got my object translating across the screen with simple matrix multiplication in DX9 but I can't figure out the sine wave path.
anyone have any ideas?
|
|
|
|
|
Move the world matrix of that object according to the sine wave.
The position of the matrix is a vector with 3 components, so create a function that returns a "sine wave" vector by giving the relative or absolute time (depends on your timing model) as function parameter and add the result vector's components to the position values of the world matrix.
How such a function should look like is quite easy.
I think you want to use the y-axis as magnitude of the wave.
So:
y = sin("angular velocity" * t);
Then you have to define a movement vector for spreading directon of the wave (let's call it v).
x = v.x * t;
z = v.z * t;
I hope that helps...

Alex

Wow .. def gonna do that man. I'll report results.
Thanks for quick reply.

I guess I don't fully understand.
I've got my timer around my render function so it only renders if the time is more than a certain value. What exactly do you mean give the relative or absolute time to the "sine wave" function? Also what would I use to calculate my angular velocity and my movement vector?
I think I'm starting to understand, thanks a lot for you help.

Well, its advanced to me anyway.
Included is the link to download the sample project and exe (Translucent_Test.exe) (too large to upload here - ~ 700k)
Run the exe to see the flickering problems.
1) The Side Nav Window will close and open with a mouse click - works fine.
2) The Top and Bottom Button (with the little arrow) scroll the buttons in this window vertically - too much flickering.
I have tried InvalidateRect, regioning, screaming, drinking, smoking, to no avail.
I'm not too worried about the sizing issues at the moment as this is just some test code. The painting issues are the major problem.
Critism is welcome, as it usually leads to a solution.
Look at the SsScrolled() method. This method is called everytime the buttons are moved up or down.

Any help would be appreciated.
Thanks.
