Hi

I am trying to change the orientation of Balloons (Up-right, up-left, Down-right, Down-left) when displayed on a pushpin.

I see it is possible on MapPoint 2004 but can't seem to program it using VB.NET

Thank you very much.
Sany

Hi Sany,

I cannot find anything in the help for this. Which methods are trying to change orientation ?

Hi Wilfried

When you write:

pp = map.AddPushpin(oLoc)
pp.BalloonState = MapPoint.GeoBalloonState.geoDisplayBalloon
if pp is a pushpin

the Balloon is printed on a random
I want to printed where it hides anything.
Other than this, i do not know any methods

Thanks,
Sany

On MapPoint 2004,

you just need to right click on the pushpin
to choose the orientation of the Ballon

Hi,

Yes I see now. But it seems that the Orientations is not made public. An alternative is maybe display a text box, and connect it with a line to the pushpin.

Ok Wilfried

Thanks, it is a shame this function is not public

Sany

Hi Sany,

Yes But maybe it's hidden somewhere...

Hi Sany,

I just needed to popup window in mappoint, did not found a method and did a workaround by sending a keyboard message. Certainly I remembered your post and tryed it out. It works well but disavantage is that you see a small flikker where balloon first pops up Anyway maybe this is workaround for you:

Code:

            PP.Select();
            Win32.keybd_event(93, 0, 2, 0);          // popup window
            Win32.keybd_event((byte)'O', 0, 0, 0);   // Orientation
            Win32.keybd_event((byte)'L', 0, 0, 0);   // Lower right

As for the Win32 call is P/Invoke for win32 API. If you need example then just ask it

Hi Wilfried

First of all thanks very much for your research
Unfortunatelly i haven't understood a thing because i don't know win32 API
I am using VB. NET to code and i don't know how ths launch these API.

Best Regards;
Sany

Hi Sany,

You will understeand soon You need this in using clause:

Code:

using System.Runtime.InteropServices;   // needed to call external application (winAPI dll)

I think in VB it is 'imports'. This is the complete class (with only one functions, but you can add others later if needed:

Code:

    public class Win32
    {
        [DllImport("User32.dll")]
        public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
    }

You can easy translate that to VB because you know the syntax probably mutch better thatn me Something like this (I think):

Code:

        <DllImport&#40;"User32.dll"&#41;> 
        Public Shared Procedure keybd_event&#40;ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags as Int, ...&#41;

So in fact that's all to do. Once you have the class whitch I called Win32, but you give it the name you want, and you need any of the win32 API functions you just add it and it works. To call this one it is just as in my previous example which you now probably better understead.

If there is still questios just fire them. There are enough VB.NET people here to assist you
