You can do some interprocess communication.
In the second application use RegisterWindowMessage() to register a custom user message, and capture that message using WndProc().
In the first application (full-screen), when you are exiting, register the custom message, then send it to all windows using:
::SendMessage(HWND_BROADCAST,id,0,0); //id is id of the message returned by RegisterWindowMessage().
The second one will catch it in its WndProc() then it can exit.
this is this.

Use ::SendMessageTimeout instead or your application might hang on the first app that is not processing messages - I can already see myself shouting this from the grave

Are you using CreateProcess() or ShellExecuteEx() for this? If so, then just retain the handle of the new process. You can then call TerminateProcess() using that handle. Another option is to send that other application a WM_CLOSE message.

In the MFC exe version,i created a thread just to protect the GUI from freezing, but is it actually need inside an ATL dll?.. the dll's going to be used by a VB application, i guess it wont freeze the VB application, but is it recommended to use threads even inside a component(ATL)?
ie, its just a do while loop
void simpleFunction()
{
do
{
}while();
}
or
UINT ThreadFunxn(LPVOID lp)
{
do
{
}while();
}
which one can be right inside a DLL?
thanx

You already know the uses of both approaches. If it is a small operation, then it will do fine without threading.
If it is lengthy, then you should use threads. Inside the threaded version, you can report back by firing events that the operation is complete etc. Also you need to make sure that the object created in VB stays alive (global) as long as the thread inside the dll is running.
Maybe someone else can give some better explanation.
this is this.

This could be a tricky one! VB and threading are like water and oil, they just won't mix well together.. at least that's what everybody is saying, including Microsoft. The thing is, if you're thread is created within the DLL and you only call the function that spawns off the thread from VB you should be OK; but only as long as you initialize OLE on that thread using CoInitialize() and then uninitialize it before the thread exits using CoUninitialize(). That is critical!!! Other than that, make sure the thread is dead before you close VB... or else  ...

Hi,
last week there was a new addition to codeproject, the CRoundButton2 class. This directly cought my attention, since I would like to add skinning and resizing capabilities to our application. But I have still a problem with this class. It can only handle text on the buttons and no overlayed bitmaps.
Why isn't there any Button class with SVG rendering capabilities. I know, I can write one myself and perhaps I will do so, but I find it interesting, since SVG is an accepted standard. There is no basic SVG rendering library available for Windows. You have to make use of adobes product or of the internet explorer. Recently there was a note that the two libraries librsvg and libsvg will join, and with the cairo backend there is also a win32 based output target available.
But I can't believe that there isn't anything currently available to render Buttons with SVG images wihin windows. Something, that is built into GTK/Gnome and QT/KDE since years.
Or, can somebody point me to the right direction? I don't want to make use of all high level features of SVGs, CSS and whatever. Simply render a button from a SVG source and have all button styles like, hoover, pressed, inactive and so on assigned a different SVG.
Best regards
Dirk
