Help with Run time error 91

EthanDunker — Thu, 04 Feb 2016 18:51:46 GMT

I am trying to create a button for ArcMap and I get Run time error 91 object variable or with block variable not set. I know the problem is one line 84 & 86. If I take them out the code runs, but it returns all my locations from the table. Also if you change the SEARCH_THRESHHOLD to 10000000, the code run with line 84 and 86 in there, but the same thing happens, it returns all my locations. I have the same code in another ArcMap and it works just fine. So I don't know what the problem is. Is there a setting I need to change in ArcMap itself? I am using ArcMap 10.3.1.

Here is the code:

Hi Ethan,

Interesting question.

Which lines are 84 and 86?

Leo.

Line 84 is:

Set pSpatialFilter.Geometry = pGeom

and Line 86 is:

SpatialFilter.SpatialRel = esriSpatialRelContains

Okay so the line switched because of extra line spaces its now line 93 and line 95.
