Hi,

What is the MapMode used for and how many options are there, I am guessing 8?

What are the results of each setting?

Also, what are External Lines and where would they be used?

Thanks,

Terry

When using External Lines, why would the following code produce the error shown in VB.Net?

Code:

Dim sName As String
Dim vItemProperties As Object
Dim iClr As Short
Dim iWidth As Short
Dim iStyle As Short
Dim iLayer As Short
Dim aResult As Integer

sName = "rectangle"

vItemProperties = ""

iClr = 1
iWidth = 2
iStyle = 0
iLayer = 0

aResult = DrawingForm.cAvax1.Add_ExternalLines(sName, "", iClr, iWidth, iStyle, iLayer)

Error:

An unhandled exception of type 'System.ExecutionEngineException' occurred in axinterop.avax.dll

The same error is produced using this code:

Dim sName As String

sName = "rectangle"

DrawingForm.cAvax1.Add_ExternalLines(sName)

Hi,

About the "mapmode" please have a look to the following link:
Windows API - SetMapMode function

About the "Add_ExternalLines" error I'm trying to find an explanation.
