Having trouble converting VB to C#
Hi,
I am trying to change a variable used in the MapPoint ActiveX control to hopefully get it to do what I need it to do. I am trying to set a variable, UserControl, to true. But it throws the exception:
"Access is denied" when I try to set it to true.
I have been digging through the Help function, which uses VB only, and have found they have used an interesting term for the UserControl. They say "Let".
Does anyone have any idea what I might try in C# to get past this exception? If the property were read only, wouldn't it say so? And how could it be read only if the help function shows that it's changable?
Thanks for the help.

Dim objApp As New MapPoint.Application
'Set up the application
objApp.Visible = True
objApp.UserControl = True
////
// a different function
Dim objApp As New MapPoint.Application
Dim objMap As MapPoint.Map
Dim objLocNY As MapPoint.Location
Dim objLocLA As MapPoint.Location
Dim objCenter As MapPoint.Location
Dim objTextbox As MapPoint.Shape
'Set up application and create Location objects
Let objApp.Visible = True
Let objApp.UserControl = True

Fernando,
Here's the code from the Help function pertaining to setting the UserControl variable.
Sub LeaveAppRunningAfterQuit()
Dim objApp As MapPoint.Application
Set objApp = CreateObject("mappoint.app
'Make the application visible
objApp.Visible = True
'Give the user control of the application
objApp.UserControl = True
End Sub

Hi Bob;
I have not used MapPoint before in a project. I have MapPoint 2006 on my system and if you would like I can attempt to run your code on my system to see if I can find the problem. If you would like me to help in that way if you would upload your complete project to the EE web site http://www.ee-stuff.com/login.php and login with your user name and password and then click on the Expert Area tab. Then you will be able to upload a zip file of your project. After the upload they will give you a link, if you post that link I then will be able to download the file and have a look at it.

Fernando,
Thanks so much for offering to help. I had no idea that EE had such a site for transmissions.
Maybe I can put together a small example program that we can work on together.
Thanks,

Very Good. Also what version of MapPoint are you using, 2002, ..., 2006?

2004
Have you completed the test project as you were going to do and upload it to the EE web site yet?
