Where you want to show this preview on the main dialog or other dialog

So just add a static control, with the SS_BITMAP style, to your dialog's template.

well sir, i did the same. but the static control does not display the bitmap image that i specify. However, is able to display the system icons (like Question mark Icon, or an Information Icon) .
i really dont know what mistake i am doing.

CStatic has a function SetBitmap(that needs to hbitmap) but before it set Type of preperty window to Bitmap

And without seeing a relevant code snippet, neither do we.

But I suggest use of foreign dialog instead same dialog you insert a CDialog to your project and show preview on that dialog if you use of this way you have more control for example you can move this window without any work or change size of show image on the dialog or insert controls to this dialog for control picture,anyway if you want to use this way on the codeproject is more articles
for example search for 3dmax,you can find an article in this article you can see behavior like 3dmax window);)

no, i dont want to have much features for the preview. i just need to show a thumbnail preview of the image icon selected. i dont want to provide the scaling options either. how can i do it???

One good way is David Crow answer other way is use of WM_ERASEBKGND for show preview of image

still cant get it work.  below is the sample code snippet that isnt working for me.
<br />
CStatic m_ImagstBox[5];<br />
<br />
m_ImagstBox[i].Create(_T("BMP"),WS_CHILD|WS_VISIBLE|SS_ICON|SS_CENTERIMAGE|SS_SUNKEN,CRect(l,50,r,100), this,1001+i); <br />
<br />
m_ImagstBox[i].SetIcon(::LoadIcon(NULL,MAKEINTRESOURCE(IDI_BMP)));<br />
in the above code, IDI_BMP is the id of the icon that i want to display. but i dont know why it is not working. if i specify something like IDI_INFORMATION, then it displays the information icon in the static control.
i even tried the SetBitnap function, to display a bitmap instead of an icon. but could not get it work. below is the sample code that i had written.
<br />
m_st[i].SetBitmap(::LoadBitmap(NULL,MAKEINTRESOURCE(IDB_BITMAP_HOME)));<br />
i am new to MFC and i am sure that i am doing a mistake some where in the code. can u please point out where i am doing the mistake?

You have two ways create CStatic on your code or insert Static control of ToolBox;).
But your problem check this code
m_ImagstBox[0].SetIcon(::LoadIcon(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDI_BMP)));
And same For SetBitmap

oh yes, now its working. I have now learnt something from that. thank u.

I have this code and it compiles without problems in my VC++ (2003):
Includes omitted.
int main(int argc, char *argv[])
{
SOCKET s;
struct sockaddr_in saddr;
WSADATA wsadata;
short listenport;
int g = 1;
listenport = 25000;
if (WSAStartup(0x202, &wsadata) == SOCKET_ERROR)
{
printf("WSAStartup failed\n");
WSACleanup();
return 0;
}
s = socket(AF_INET, SOCK_DGRAM, 0);
if (s == INVALID_SOCKET)
{
printf("Error opening listen socket\n");
WSACleanup();
return 0;
}
saddr.sin_family = AF_INET;
saddr.sin_addr.s_addr = INADDR_ANY;
saddr.sin_port = htons(listenport);
if (bind(s,(struct sockaddr *)&saddr, sizeof(struct sockaddr_in)) == SOCKET_ERROR)
{
printf("Bind failed\n");
closesocket(s);
s = INVALID_SOCKET;
WSACleanup();
Sleep(1000);
return 0;
}
//more irrelevant code
}
Purpose of program: Read incoming UDP packets (ints, shorts and floats mixed).
Now the question: If I just run the program and listen to port 25000 as in the code it will run through this code. But if I start another (any) program that communicates through UDP on port 25000 I will get "Bind failed" and I don't understand why from all the documentation I've read. I thought it would bind (at least as long as the communication is UDP) no matter what.
I saw the timecli and timeserv demo UDPs in this site and when I look at that code it is so similar that I can't understand why this won't work.
I hope this question is clear.

Can you check the error code it is returning ?

As expected, WSAGetLastError() returned 10048, meaning socket address already in use.
Since I do open the port with another program, that sounds logical. But I thought this would work because I'll just read what is sent out on the port by the server (the other program).
--EDIT--
So I tried changing bind to connect (same arguments and everything). It seems to run through the connect call.
However, after the connect(...) I use the "recv(s,buf,512,0)" function to receive data from the UDP port. For some reason my debug gets stuck at this function.

Sounds like your socket is in blocking mode. You need to use the socket asyncronously.
There are many ways to do this - non-blocking socket mode, overlapped I/O, blocking socket on
a separate thread,...
Great job, team. Head back to base for debriefing and cocktails.

Hello all,
I need a control to have the focus all the time, but I need also to be able to click other buttons and controls.
What I'm doing now is to place the focus to that control again and again via a OnTimer message handler.
I'd like to know if there is a better approach to do that than:
1. using the timer like now.
2. setting again the focus to that control after pressing any of the other controls that are on the dialog.
The problem here is that if I set the focus to the control then the onclick events that I have in the other controls sometimes fail.
As always thank you in advance.

What you're proposing isn't practical. Imagine if two programs did it. Each one would constantly steal the focus away from the other (by definition, only one window can have the focus).

OK, but in my case this is a must: this is an app that loads when a machine start and it is the HMI for the operator of that machine so this is the only program that can be run on the PC. So there is not any possibility of problems with other programs.
By the way, thank you for your feedback.
