I am trying to use the MapPoint control in a C++ .Net 2003 program. There is a SelectionChanged event which has a pointer to the selected object. But when I try to find out what type of object was selected with the GetType function, all I get is System._ComObject. Most of the MapPoint examples use Visual Basic and the Typeof operator. How do I figure out what type of object is selected in C++?

Check FindWindow and SendMessage (and WM_CLOSE)

you can close program by two method
1. by sending WM_CLOSE, you have to find the window using FindWindow function.
2. using TerminateProcess(hProcess, 0), you need to find the process id (pid)
I find the other method better, if the application have many threads, for example when you exit the visual studio, its running many threads in background. Its hide the window but takes time to clear all the threads. you can see it from task manager.
// Shail [11/11/2002]
const CString ConfigPage::ProcessTerminate(int nApp, bool &bSuccess) const
{
CString msg;
DWORD pid = 0;
HANDLE hProcess;
CCSITimer oTimer;
bSuccess = true;
SetCursor(LoadCursor(NULL, IDC_WAIT));
pid = GetPIDfromAppName(m_strProcessApps[nApp]);
if (pid)
{
// open the process with all access
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
// bye-bye
if (hProcess)
{
TerminateProcess(hProcess, 0);
oTimer.Start();
while ( ( pid )
&& !oTimer.IsElapsed( PROCESS_TERMINATE_TIMEOUT ) )
{
Pump();
oTimer.Delay(500);
pid = GetPIDfromAppName(m_strProcessApps[nApp]);
}
if ( pid == 0 )
msg.Format("%s Terminated.", m_strApps[nApp]);
else
bSuccess = false;
}
}
return msg;
}
const CString ConfigPage::ProcessDistroy(int nApp, bool &bSuccess) const
{
CString msg;
CWnd * pWnd = NULL;
CCSITimer oTimer;
SetCursor(LoadCursor(NULL, IDC_WAIT));
if (m_strApps[nApp].IsEmpty())
return msg;
pWnd = FindWindow(NULL, m_strApps[nApp]);
if (pWnd )
{
pWnd->PostMessage(WM_CLOSE);
if ( C7StartupConfigPage::nDS == nApp )
{
msg.Format("Close %s Manually.", m_strApps[nApp]);
}
else
{
oTimer.Start();
while ( (NULL != pWnd)
&& !oTimer.IsElapsed( PROCESS_TERMINATE_TIMEOUT ) )
{
Pump();
oTimer.Delay(500);
pWnd = FindWindow(NULL, m_strApps[nApp]);
}
if ( NULL == pWnd )
msg.Format("%s Terminated.", m_strApps[nApp]);
else
bSuccess = false;
}
}
else
{
// Shail [11/11/2002]
// if app window doesn't exists, then just terminate the app. [ most prob. its a crashed app.]
ProcessTerminate(nApp, bSuccess);
}
return msg;
}

Hi,
Background:
A GUI (VB DLL) is running off an application, which has some button on it. And VC++ DLL is also referenced in the same application and same thread.
Question:
What I want to do is when I press the button on GUI, the VC++ project should be able to catch that particular event. Basically making VC++ a client of the GUI (VB project) somehow, I guess.
Someone advised me to use IConnectionPoint interface, which can help to catch this particular "button click" event. But after reading from MSDN, I was not sure how this could help.
Anybody who has used IConnectionPoint interface before and can help me out with this problem.
Any help is appreciated.

Hi, I'm porting a macintosh application to windows. And I was wondering if there is an winapi/MFC alternative for the function WaitMouseMoved (http://developer.apple.com/documentation/Carbon/Reference/Drag_Manager/drag_manager/function_group_13.html#//apple_ref/c/func/WaitMouseMoved)
Thanks

Not exactly the same. But I've found what I was looking for: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/UserInput/MouseInput/MouseInputReference/MouseInputFunctions/DragDetect.asp
Thanks anyway!

First. I get weird random errors when I miss a semi colon off the end of a class definition. Each time I do a compile with it missing it seems to bring up a different error each time I hit build. In one case about an .sbr file missing. Generally though it thinks there are errors with other header files, but not that fact that you have missed the semi colon off the end of the definition.
Second thing. In the MSDN documentation for an stl::queue, according to the MSDN docs its says that for the .back and .front methods both say
Return Value : The last element of the queue. .
A bit of copy and pasting probably. Anyway, just wanted to let you know. I'm fairly sure VC6, gave odd errors, but that they were always the same, about end of file reached before end of class definition or something.
Anyone want to confirm the the front is the next item to be popped?

Does anyone here have example code that show how to send a WM_VSCROLL message to a CListCtrl control using SB_THUMBPOSITION, SB_THUMBTRACK, and SB_ENDSCROLL to scroll a listctrl?
I have watched spy++ and can clearly see that these are the messages that are being sent to the CListCtrl when dragging the thumb control of CListCtrl's scrollbar, but I can't get the list to scroll by doing SendMessage commands to the CListCtrl. Can anyone post sample code on how to do this properly if it is possible?
Thanks,
Greg

What about Scroll( CSize size )?

I have tried that, but it does not work exactly the same as the WM_VSCROLL message. The blting that it does is very poor. If I was able to somehow send the WM_VSCROLL message it would solve all my problems.
Cheers,
Greg

Hi.
Why sometime the intellisense feature disappear?.
I'm writing an aplication, and suddenly I don't have any more the intellisense feature, (for example the list of methods and fields of an object, etc).
I have Visual 6.0 Enterprice edition.
Should I install some patch or something like this.
Thank you.

It just does (no matter what patch has been applied). In the project's folder, delete the .ncb file. Open the project again and that file will get recreated.

How can i insert code in my function, that stored in other file?
|
|

I don't really understand your question, but the Visual Studio editor, or Notepad, come to mind.

Are you talking about source code? If so then copy/paste in whatever editor you use notepad, visual studio, etc. will work.
Greba,

hi
when i was programming with BC and i would like to override a specific func of its libraries, eg. atan2, it was enough to put the same function with the same name and prototype in my own code, in one of my source files. then the BC would generate a warning, but replaced the original func in the link with my code.
this was the only method i knew for overriding system funcs, mostly used for debugging them.
do u know how can i do such a work in VC? i need to debug AfxInternalPumpMessage().
thanx

Is this a v7.x function? In any case, set a breakpoint on the call to that function, or if it is not being called directly, set a breakpoint somewhere within the function itself.
