Hi,
I recently got a answer to a question regarding a CwinThread question
I was pointed to a article on the code project
the following is the URL wwww.codeproject.com/KB/threads/extended_thread_aspx
my question is regarding the following snipet of code from the Article
CThreadEx::CThreadEx (AFX_THREADPROC pfnThreadProc) : CWinThread (pfnThreadProc, NULL) {
m_bAutoDelete = FALSE;
// Undocumented variable. Need to set the thread parameters variable to this
m_pThreadParams = this;
}
The author uses a inilizer list to pass paramters to the base Class'es contructer I have no problem
With this
My problem is the next line of code m_pThreadParam = this
The author points out that this contructer isn't the one documented AFXWIN.H
However I found a more complete discription of the CWinthread in the following PPT
presentation below is the URL
ttp://74.125.47.132/search?q=cache:azRHOpLik8MJ:www.ecs.syr.edu/faculty/fawcett/handouts/cse778/Lecture7/Additional%2520Thread%2520Info/threads.ppt+MORE+ON+THREADS+BUKIN&hl=en&ct=clnk&cd=1&gl=us
Anyway on page 5 of the PPT presentation is a more complete descrption of the CWinThread
Class
and m_pThreadParams seems to be a private member of the base Class CWinThread Class
I haven't build the code in the article but I am wondering if it would work

The first URL you mentioned, I believe is wrong. That is, it starts off with 4 W's. However, even after deleting the extra "W", I could not get there. Are you sure you have the right URL?

Sorry you are right
the second one the titled more on threads by Konstatin page 5 has a detailed listing CthredWin
private:
LPVOID m_pThreadParams; <--- is a private data member //generic parameters passed to starting function
AFX_THREADPROC m_pfnThreadProc; ,

Just cut and paste the link below

I use these two functions that I have copied from codeproject to use transparent static text and background in my application. But everytime I put a command button in my application the application seems to run for milliseconds and vanishes without me closing out. I am a beginner and any suggestion would be great thank you.
HBRUSH CTrialDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr;
if( nCtlColor == CTLCOLOR_STATIC )
{
pDC->SetBkMode(TRANSPARENT);
//pDC->SetTextColor(RGB(255, 0, 0));
hbr = (HBRUSH)GetStockObject( NULL_BRUSH );
}
else
{
hbr = CTrialDlg::OnCtlColor(pDC, pWnd, nCtlColor);
}
return hbr;
}
BOOL CTrialDlg::OnEraseBkgnd(CDC* pDC)
{
CBitmap m_bitmap;
BOOL rVal = FALSE; //CWizardPage_Base::OnEraseBkgnd(pDC);
if( m_bitmap.LoadBitmap( IDB_Background ) )
{
CRect rect;
GetClientRect( &rect );
CDC dc;
dc.CreateCompatibleDC( pDC );
CBitmap* pOldBitmap = dc.SelectObject( &m_bitmap );
pDC->BitBlt( 0, 0, rect.Width(), rect.Height(), &dc, 0, 0, SRCCOPY);
dc.SelectObject(pOldBitmap);
rVal = TRUE;
}
return rVal;
}

Shouldn't that be CDialog::?

Yeah It should have been CDialog. Thanks for that.
But I have got another problem now. I am using arrays to display text through my static text and everytime I am displaying the next question, the text is overlayered above the previous one. Is there any function to flush the text...
thank you..
snippet of my code for displaying static text from array:
m_QUESTIONS.SetWindowText(Questions[counter]);
m_cAnswer1.SetWindowText(Answers[counter][0]);
m_cAnswer2.SetWindowText(Answers[counter][1]);
m_cAnswer3.SetWindowText(Answers[counter][2]);
m_cAnswer4.SetWindowText(Answers[counter][3]);

Don't get your question fully. May be you are looking for a "setWindowText("")"? Guess
not. Ok dinner time. May be back in 30 mins.

I will probably scratch the head of my tutor for this one. Anyway thanks for the effort...

I have an application that is running on a japanese machine and it seems that the code in that application is not working properly.
It is having a char a[256] array and it looks like the char array is not getting populated with a string.
In all strcpy(a, "test is here") is not working. Is this something related to unicode stuff on japanese locale. Will usage of tchar solve the problem?

But you will have to replace those functions with equivalent _tcs functions. If you want to completely move to UNICODE and no looking back, you can choose wchar_t and the corresponding wcs functions.

Application uses multibyte character set but the symbol _UNICODE is not defined. Nit sure if the LOCALE Japanese can make the application to run in Unicode format?

You mean "And"?
When you declare, MBCS, you should not use UNICODE. And Japanese letter would work with UNICODE. Remove MBCS if you had defined in your settings. and add UNICODE,_UNICODE.

Sorry to not make you understand. The project uses MBCS settings. It can't be set to unicode settings.
I was thinking if this app is made to run on a japanese m/c is there a way that locale settings could turn the application to be unicode aware.Is that is the case, since my application code used char array and strcpy function would it make it compulsory to change the application code to use -tcscpy and tchar array. This application code works perfectly on a my system.

Then use the character mapping routines in tchar.h. It'll handle MBCS, Unicode, or ANSI. Just learn the equivalent string functions for it.

Probably because your system isn't a Japanese one. Just use the character mapping routines in tchar.h and you'll be ok.

Hi to All,
First of all thanks to all for replies to my previous post.
I am going to do an simple chat application on a network(LAN).Using MFC.I wanted an advice whether to do it as dialog based, SDI or MDI? The application should be more or less the same as GTalk
Please advice for both client and server.
Thanks in Advance
I am a beginner

I will start with dialog based application... with some pretty custom drawings...

thanks for your reply,
But what about the server? can that be also dialog based, since there will be many clients. So i was wondering if it has to be an console based application.
I am a beginner

Sorry. I am not much experienced in socket programing.
But if you are going to create a gtalk like application peer to peer model is enough.

You could make your server a service.

thanks for your reply ns ami,
And sorry that was for code-o-mate.
anyway,do you mean "cleint-client" by "peer to peer"

I am not sure about the terminology. But AFAIK, in peer to peer, server and client will be in the same application. Each application will keep a list of its contacts and at the starting of application it can broadcast or send some messages to each contacts. So that others can know that you are logged in.
This is only my fair concepts...
