MapForums

Hi,


How do i check if the mappoint control is loaded on the PC or not?
If the mappoint is not loaded i need to display a message to teh user of my application.
I need to do this in code.

Thanks in Advance

Hi Rowter,

In VB6 (look up your language equivalent) I would've done this:

On Error Resume Next
CreateObject("MapPoint.Application")
If Error.Number > 0 Then
Msgbox "Notification"
Exit Sub
End If

Hi Mattys,
Thanks for the reply.

Today while testing our application we came across a scenario where in Mappoint was installed on the client computer but, our application was not seeing the mappoint.
This is the first time mappoint is accessed on that client PC.
I tried registering the mappoint using regsvr32 that did nto help.
Then i went to Program Files -> Microsoft Mappoint and lauched the application.

When i did that, our application could see the mappoint and we did not have a problem after that.

Now, to avoid this kind of scenario, we were thinking of checking whether mappoint can be detected by or application or not. If not, we want to popup a message.

When i looked at the createobject function on msdn, it says that this code creates a object.
dim mapobj = createobject("Mappoint Application")

But in the scenario i explained, application errors out the moment it tries to create the object.

Thanks

Hi Rowter,

I know exactly what you mean; it's sort of a 'first run' screen.
Perhaps the runtime installation outlined in Help would remedy this?
Otherwise, you just need to make sure that MapPoint has been opened once.
