It's allowed only if you have a declaration before the function is referenced.

Here is my small issue
SocketThread = AfxBeginThread(ReceiveMessage,this);
UINT static ReceiveMessage(LPVOID pParam)
{
return 0;
}
Since i'm not defining this class inside the Header file i'm not able to access any controls and its values. Previously i had as like below
strSocketData.SetWindowText (strResult);
//strSocketData is a control variable.
How can i access it in my "ReceiveMessage" method.

Yes it sounds Good... i can able to read and write data.
Shall use this?. Is it it advisable?. Make sure i'm using it in MFC Activex control. You mentioned that it is not safe is there anyother alternate.
CYourDlg* pYourDlg = reinterpret_cast< CYourDlg* >( pParam ); pYourDlg->strSocketData.SetWindowText( pYourDlg->strResult );

Well did it work? 
sivaprakashshanmugam wrote: You mentioned that it is not safe is there anyother alternate.
No it's not at all thread safe to pass around MFC objects. Instead pass the HWND of your dialog. Then use SetDlgItemText to set the text for the item.
SetDlgItemText( hDialog, IDD_DIALOGCONTROL_ID, _T( "This is thread safe" )); Well you cannot retrieve the strResult parameter too. To get around this store the buffer of strResult inside another pointer. Put both the handle to the dialog and the pointer to the buffer inside the struct and then pass this struct object to the thread.

DLL's can evolve (progress) into EXE's over the course of a project or the lifetime of the product. Generally the rate of change would be too slow to display in a progress bar.

Is it possible to mark certain percentage of completion?

That's what a progress bar is for. I must not understand your question.
|
|
|
|
|
Can we have any access to DLL loading process and display/update it in progress bar?
|
|
|
|

Depends on what you mean by "loading". The OS loader is going to load a DLL so fast you don't need to show progress. Now if you initialization stuff in the DLL (like running database queries) that you want to show progress for you have to supply an interface for obtaining that progress information.
There is no magical way to show progress because, progress of "what". You have to account for the knowledge of the "what". That is your job as a programmer. It is sometimes referred to as "the domain". Check it out[^]

If you write the function, you can make it do whatever you want, within the limits of your skill as a programmer.
Is that really what you meant to ask ?

I'm using GDI / CDC to draw a chart control and would like to draw the chart series antialiased. Currently the line chart is drawn using CDC::Polyline, which is fast but not 'pretty'.
In the GDI+ documentation I couldn't find a method to draw a polyline, only a polygon which is not exactly the same.

Use one of the GraphicsPath::AddLine() overrides to add the points, do not call GraphicsPath::CloseFigure() as that will cause a line to drawn from the last point to the first point. Call Graphics::DrawPath() to draw the lines.
You may be right
I may be crazy

In MDI project: how can I add my file extensions filter string to dialog window CFileDialog ? It is displayed automaticly, when user press FILE/OPEN... menu. How and where can I modify this dialog?
For example: when I'm displaying CFileDialog I can add filter by myself, like this:
static char szFilter[] = "Pliki BMP (*.BMP)|*.BMP||";
CFileDialog FileDlg( TRUE, NULL, NULL,
OFN_HIDEREADONLY, szFilter );

If you don't want to derive your own class and override functions, you can edit the string table in the resource editor. Locate the resource that is associated with your CDocTemplate (like IDR_MAINFRAME).
The string will look something like:
Test Application\n\nMFCTest\n\n\nMFCTest.Document\nMFCTest Document
Change it to:
Test Application\n\nMFCTest\nPliki bmp *.bmp)\n.bmp\nMFCTest.Document\nMFCTest Document<br />
If you need to do anything more complicated, like multiple extensions per doc template, check out this article:

So I only have to make my own class (document template) derived from CMultiDocTemplate, use it like here:
pDocTemplate = new CMyMultiDocTemplate(<br />
IDR_CONTEXTTYPE,<br />
RUNTIME_CLASS(CMyDoc),<br />
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyView));<br />
AddDocTemplate(pDocTemplate);
and then override function DoPromptFileName() in this class? Or is there anything more to do?
And how can I use my own filter string in DoPromptFileName()? I don't know how to do this.
Thanks for any help.

I'm trying to figure out why my CSocket.Receive() call is blocking. This is the code I have so far:
CSocket socket;<br />
<br />
socket.Create();<br />
ret = socket.Connect(m_sAddress, m_nPort);<br />
<br />
if (ret == 0)<br />
{<br />
<br />
GetSocketError();
return -1;<br />
<br />
}
<br />
m_TotalBytes = 0;<br />
<br />
<br />
while(m_bRunThread)<br />
{<br />
<br />
BYTE* pBuffer = new BYTE[MAX_BUFFER_SIZE];<br />
ret = socket.Receive(pBuffer, MAX_BUFFER_SIZE);<br />
<br />
<br />
........<br />
}<br />
The socket connects but never receives any data. The call to Receive seems to block the thread. I know the server program I am using is working because I can transfer data to other clients without a problem.
Any suggestions? Thanks

Use CAsyncSocket instead of CSocket. CSocket assumes synchonous communications (that is, you will send, then wait for a return message).
An alternative is to put the socket's receive call in a worker thread that fires off an event when it receives data in the buffer.
