RE: [V8i C#/.NET] mdlDimStyle_setBoolIntProp

[quote user="clever_anthony"]I guess that the option is relative to DIMSTYLE_PROP_ExtensionLine_ShowAny_BOOLINT[/quote]

With software development, guessing is bad.

[quote user="clever_anthony"]However, the "mdlDimStyle_setBoolIntProp" is not working
mdlDimStyle_setBoolIntProp(0, 1, 211)[/quote]

It's not working because you're not setting a dimension style.

The first parameter is a pointer (in MDL) to a DgnDimStyle.  You've passed value zero, which is a pointer to nothing.  You need the address of an MDL  DgnDimStyle.  You can get a pointer to (i.e. the address of) the active dimension style using mdlDimStyle_getActive.  Here's the VBA declaration, which you must modify for C#...

Declare Function mdlDimStyle_getActive Lib "stdmdlbltin.dll" ( ) As Long ' Returns a pointer to a structure 

Modify your call to this...

mdlDimStyle_setBoolIntProp (mdlDimStyle_getActive (), 1, 211);
