get names of blocks using wildcard

Anonymous — Tue, 06 Apr 2010 19:54:32 GMT

Hi. Is there any way to get blocks using wildcard character?
For example, selection set block name filter X111*01 will return:
X111zzz01
X111bbb01
X111cccccc01

Is there any way to do this is vb.net? Thanks...

You can use wildcards in a selection filter.
Dim myfilter() As TypedValue = New TypedValue() {New TypedValue(0, "INSERT"), New TypedValue(2, "PAT*")}

and you can 'Or' them together to get more than one pattern to match

Dim myfilter() As TypedValue = New TypedValue() {New TypedValue(0, "INSERT"), New TypedValue(DxfCode.Operator, "")}

Sorry, I was just digging around for a bit of code I remember seeing, and I realized that the text in my post is incomplete. I'm not sure if I did that. or the site, but just in case you still need it, or if anyone else comes here looking for an answer, here is a complete filter definition using Or's and Wildcards

Dim myfilter() As TypedValue = New TypedValue() {New TypedValue(0, "INSERT"), New TypedValue(DxfCode.Operator, "<or"), New TypedValue(2, "Blk1*"), New TypedValue(2, "Blk2*"), New TypedValue(DxfCode.Operator, "or>")}

(Then you can create a new SelectionFilter passing the TypedValue Array to the constructor)
