#NIM076610 While the bug report specifically refers to a console application, I have determined that it also occurs in ArcMap. ... View more

It does seem that ST_GEOMETRY is the culprit.  I migrated my test data to SDELOB and the test succeeded, then migrated it back to ST_GEOMETRY and the problem reappeared. This morning I thought that I was getting SDELOB to fail with production reports, but it turns out I was not pointing them to the test GDB.  The SDELOB storage is working fine so far, so unless I can get my tests to fail I'm still going to recommend migrating our production data away from ST_GEOMETRY. ...

One more question:  how do I control the units it displays?  I can set english vs. metric, but what if I always want it to display feet? ... View more

Thanks, I had only seen the first example in the docs and not the second. ... View more

The ScaleLine really seems to be a step backwards.  Is there any way (i.e. an ACTUAL EXAMPLE) to get it to look and behave the way the ScaleBar did? ... View more

Multiple add-ins, multiple dialogs, no problem.  Button, ComboBox, and RadioButton events work fine; I haven't tested any others.  One other quirk I noticed:  print, when executed from a dialog, does not output to the Python window. ... View more

I can get wxPython to work in an add-in, EXCEPT that Destroy() doesn't work.  For example: import arcpy import pythonaddins import wx class TestButtonClass(object):     """Implementation for wxTest_addin.TestButton (Button)"""     dlg = None     def __init__(self):         self.enabled = True         self.checked = False     def onClick(self):         if self.dlg is None:             self.dlg = TestDialog()         else:             self.dlg.Show(True)         return class TestDialog(wx.Frame):     def __init__(self):         wxStyle = wx.CAPTION | wx.RESIZE_BORDER | wx.MINIMIZE_BOX |wx.CLOSE_BOX | wx.SYSTEM_MENU         wx.Frame.__init__(self, None, -1, "Set DataFrame Name", style=wxStyle, size=(300, 120))         self.SetMaxSize((300, 120))         self.SetMinSize((300, 120))         self.Bind(wx.EVT_CLOSE, self.OnClose)         panel = wx.Panel(self, -1)         self.lblStatus = wx.StaticText(panel, -1, "OK", pos=(8, 8))         wx.StaticText(panel, -1, "Title:", pos=(8,36))         self.tbTitle = wx.TextCtrl(panel, -1, value="", pos=(36, 36), size=(200,21))         self.btnSet = wx.Button(panel, label="Set", pos=(8, 66))         self.Bind(wx.EVT_BUTTON, self.OnSet, id=self.btnSet.GetId())         self.Show(True)             def OnClose(self, event):         self.Show(False) # self.Destroy() doesn't work     def OnSet(self, event):         # Use str() to strip away Unicode crap         sTitle = str(self.tbTitle.GetValue())         mxd = arcpy.mapping.MapDocument("CURRENT")         df = mxd.activeDataFrame         df.name = sTitle         arcpy.RefreshTOC() app = wx.PySimpleApp() app.MainLoop() I haven't yet investigated the consequences of having more than one add-in using wxPython. ...

I notice that threading.Timer, or indeed any implementation of threading, doesn't work in ArcMap Python.  I'm assuming this is a related issue? ... View more

arcpy.da blows away ArcObjects for accessing table fields in a file gdb: ArcObjects/comtypes (Shape_Area): 13 sec arcpy.SearchCursor (Shape_Area): 65 sec arcpy.da.SearchCursor (Shape_Area): 2 sec arcpy.da.SearchCursor (SHAPE@AREA): 14 sec ... View more

This thread has been brought to my attention, and it seems there are some misconceptions floating around. You do NOT need Visual Studio, or the MIDL compiler, or even PythonWin in order to use ArcObjects in Python; all you need is the comtypes package. My presentation included an advanced exercise in creating a COM component using Python, but that was meant for UberPyGeeks. The snippets.py file contains all the examples you need. ... View more

The old ArcScripts site had a mechanism for contacting the author.  I don't like the new systems but I hear they're changing.  Anyway, my website has an email link:   www.pierssen.com ... View more

In theory it can be done, but you always have to watch out for controls that have restricted content, keeping them from rendering to a WriteableBitmap (WBM).  Basically, create a WBM the size of your layout, create a WBM for each child control, and paste it all together.  Pretty much all the code you need is in the PDFExporter class itself:  check out the AddElements method. ...

Sorry I'm not understanding the organization of your app.  If MainApp creates both Home and PDFExporter objects, and Home contains the map object, you could simply add a property or method on Home that MainApp could call to get a handle to the map and pass on to the exporter. ... View more
