Above link illustrates how to highlight shapes when mouse cursor is over.

`public void ShowAttributes([AxMap](https://www.mapwindow.org/documentation/mapwingis4.9/class_ax_map.html) axMap1, string dataPath, ToolStripStatusLabel label)`

{

I have to give ToolStripStatusLabel label as parameter in the method. What is the ToolStripStatusLabel label? Is it comes from From design part?  
How can I get it?

Hello.

The example just happens to display the results in a ToolStripStatusLabel. But it doesn’t have to be that. It can be a standard Forms.Label, or a TextBox, etc.

It shows this error when I run the program…

```
Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

We will need more information, like seeing the code and the line number that had the error.

Thanks.
