For my WinSock how can i show green and red signal for connected/not connected respectively? Do we have any thing in Controls in Resource editor that could be used(eg: Picture control)?

A picture control is one way. You could use two icons - one red, one green -
and set the control's icon appropriately.

Sure. Are you using MFC or straight Win32?

Here's some of the operations involved:

Add 2 icons to your app's resources - here I'll assume they are custom size
10x10 icons, with IDs IDI_INDICATORRED and IDI_INDICATORGREEN.
Draw the icons the way you want them to look.

Then...

// Add as member of window or dialog class
CStatic m_IndicatorStatic;
...

// In OnCreate() (for a window implementation) or OnInitDialog() (for a dialog implementation)...
//   (for a dialog, if the picture control is a resource on the dialog, and m_IndicatorStatic is already
//     associated with the control, then don't do the Create() call)

//  (Adjust passed CRect to properly position control in window's client area)
if (m_IndicatorStatic.Create(NULL, WS_CHILD | SS_ICON, CRect(0,0,10,10), this, ID_INDICATORSTATIC))
{
   m_IndicatorStatic.SetIcon((HICON)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDI_INDICATORRED), IMAGE_ICON, 10, 10, LR_SHARED));
}
...

// Later...Change the indicator to green
m_IndicatorStatic.SetIcon((HICON)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDI_INDICATORGREEN), IMAGE_ICON, 10, 10, LR_SHARED));

Hope that helps a bit!

// Add as member of window or dialog class
CStatic m_IndicatorStatic;

where do i add this IDI_ICON1 as CStatic m_IndicatorStatic?
I tried in class wizard but didnt find this ID....

In the properties for resources, you should be able to change the ID to whatever you want.

IDI_ICON1 sounds like the default ID - you can use that as well. It's just not as meaningful in the
code as an ID that's more descriptive.

changing the ID is fine but that's not my point.....my point is:
once i change the ID name to whatever ...IDI_ICON1 or IDI_ICONREDBUTTON, after that how do i associate it with the variable
CStatic m_IndicatorStatic , as i didnt find any Icon in class wizard

I showed an example of setting a picture control's (which is a static control) icon
at runtime. "m_IndicatorStatic.SetIcon(..."

The icon is the picture. The static control is what draws the picture.

My view class is derived from CRecordView(). And I have a socket event, OnConnect() where i would like to display Red icon. Similarly on OnClose() it would display Green Icon in place of the Red one. Also my project is SDI application.
How can this be done??

Mark Salsbery31-Aug-07 7:46

I showed code to set the control's icon. You can do that wherever you want.
Just set the control's icon to the appropriate one.

Depending on where you get the socket event notification, you may need to post a message
to the appropriate window containing the control.

Maybe that[^] would help ? I know that there are some other controls so if you search through the articles, you'll probably find some more.

Little tips for coding:
1) use longer names for varaibles and functions (this helps to understand what the code do)
2) do not use goto OMG | :OMG:

... find other ways when possible: in your case you can return -1; or something similar

having been brought up from coding raw hex on an 8080 SDK through Assembler and on into C and C++ I have no qualms about using goto. goto is after all just a JMP return -1 is also a JMP. break is also a JMP.

why are you threatened by goto?

David Crow31-Aug-07 5:54

Because you don't goto the middle of another function.

obviously you have never disassembled BIOS. JMPing into the middle of functions is common practice in every BIOS I have ever disassembled.
