Hi all, I've written a script in which I analyze the TOC content in a selected map document. The analysis produces a list of datasets (table, shapefile, geodatabase fc, raster, mosaic dataset, etc...) in the TOC. If a dataset has missing datasource the information will be also reported. Python code: import arcpy # [.....] mxd = arcpy.mapping.MapDocument(mxdFilePath) # [.....] dtfs = arcpy.mapping.ListDataFrames(mxd) for dtf in dtfs:        for dts in arcpy.mapping.ListLayers(mxd, "", dtf):                if dts.supports("DATASOURCE"):                        if not arcpy.Exists(dts.dataSource):                                file.write("\t  Missing datasource!  \n")                        else:                                # do something............. So I've created a Toolbox (tbx), added the script e run it: everything works well. I've also embedded that script in a Python Toolbox (pyt) and run it: everything works well but Personal Geodatabase feature classes return always a "missing datasource" message, althought the data exist and datasources are correctly set. Finally, If I run the pyt script as shown here​, again everything works well. So, I do something wrong in my Python Toolbox..... but what? Any help please? Using Python 2.7.2 and ArcGIS 10.1.

Hi, I wrote this code to loop in my TOC:         Dim iLyrIndex As Long         Dim layer As ILayer         Dim geoDataset As IGeoDataset         ' Add raster layers into Combobox         Dim iLayerCount As Integer         iLayerCount = map.LayerCount         If iLayerCount > 0 Then             For iLyrIndex = 0 To iLayerCount - 1                 layer = map.Layer(iLyrIndex)                 If (TypeOf layer Is IRasterLayer) Or (TypeOf layer Is IMosaicDataset) Or (TypeOf layer Is IRasterCatalogLayer) Or (TypeOf layer Is IGdbRasterCatalogLayer) Then                     cboBox.Items.Add(layer.Name)                ' <---- mosaic dataset DO NOT shows here!                 Else                     MsgBox(layer.Name)          ' <---- mosaic dataset shows here!                 End If             Next iLyrIndex         End If The code works well with raster layer and raster catalogs, but not with raster mosaic dataset. If I double-click on the mosaic dataset in the TOC (grouping the Boundary, Footprint and Image layers) and then the "Source" tab in the Layer Properties Dialog the Data Type is Mosaic Dataset. So, what's wrong? Please, any help? Thanks a lot in advance ... View more

I need to set a default value for a Boolean parameter in my Python toolbox, but I didn't found any documentation about that. I'm able to do it using the custom toolbox wizard, but I found nothing on how to do the same in a python toolbox. Any idea?   Thanks ... View more

Hi, I've to calculate a field based on another field in a joined table, but an error occurs: "Parameters are not valid. ERROR 000728: Field !Table_A.field_A! does not exist within table" import arcpy from arcpy import env env.workspace = "C:/TMP/BASELINE.gdb" Table_A = "dist" Table_B= "matrix" arcpy.AddJoin_management(Table_A, "id_grid", Table_B, "id_matrix") arcpy.CalculateField_management(Table_A, "!" + Table_A + ".field_A!", "!" + Table_B + ".field_B!","PYTHON") Both tables are in the BASELINE.gdb. The Join occurs without any problem. Please, any help appreciated. Thanks in advance ... View more
