Hello,
I create a MapPointApplication with the following code:

Code:

ApplicationClass mapPointApplication = new ApplicationClass();

Then I add pushpins to it:

Code:

mapPointApplication.ActiveMap.AddPushpin(location, "1");

How can I check if MapPoint is still running and hasn't been closed by the user?

Bye,

MD

Hi,

Something like this:

Code:

using System.Diagnostics;

        private bool IsMPRunning()
        {
            Process[] processes = Process.GetProcessesByName("MapPoint");
            return (processes.Length > 0);
        }

I did not test this, just from the top of my head

I thought about this one, too. But the problem could be: The user could have closed MapPoint and restarted it. So with your method, I wouldn't be sure if it is the same MapPoint instance that I created before.

Hi,

I cannot find ApplicationClass in my help

But I'm pretty sure you can retreive his windows handle. Later when you wants to check if this particular instance of Mappoint is still running you can probably do it this way:

Code:

        private bool IsThisOneRunning(IntPtr h)
        {
            Process[] processes = Process.GetProcessesByName("MapPoint");
            foreach (Process proc in processes)
                if (proc.Handle == h)
                    return true;
            return false;
        }

I thought about something like this:

Code:

mapPointApplication.BeforeClose += new MapPoint._ApplicationEvents_BeforeCloseEventHandler(mapPoint_Closing);

But the code is not totally right.
I'm not so familiar with eventhandler. Do you know how add the right event handler for the beforeclose Event?

Here's the Visual Basic code from the MapPoint help:

Code:

  Dim WithEvents objApp As MapPoint.Application

  Private Sub Command1_Click()
    'Refresh the map using NewMap
    objApp.NewMap
  End Sub

  Private Sub Form_Load()
    'Set up the application
    Set objApp = CreateObject("mappoint.application")
    objApp.Visible = True
    objApp.UserControl = True
  End Sub

  Private Sub objApp_BeforeClose(Cancel As Boolean)
    MsgBox "BeforeClose event fired"
  End Sub

How do I add this event handler in C#?

Bye,

I cannot get it work

The constructor should be:
new MapPoint._ApplicationEvents_BeforeCloseEventHandle r(void (out bool) target)

How should the signature of the mapPoint_Closing methode look like?

Hi,

I'm not sure:

Code:

public void Map_BeforeClose(ref bool Cancel);
new MapPoint._ApplicationEvents_BeforeCloseEventHandler(Map_BeforeClose)

MD2000 · #9 (**permalink**) 03-03-2005

It says:

Method 'server.ServerGUI.mapPoint_Closing(ref bool)' doesnt comply with the Delegat 'void MapPoint._ApplicationEvents_BeforeCloseEventHandle r(out bool)'.

Any idea? I'm totally lost with the delegat and out thing.

Bye,

MD

Hi,

Try with Ref bool
