I published a GP service to ArcGIS server. I found that the operation speed is extermely slow because of the function ListDataFrames. To define a dataframe object with respect to my mxd, it spended 3 mins. Actually, I do not need to change the dataframe in my operation. Therefore, it wastes the time on defining the dataframe object when the GP service is called each time. Is any method to define the dataframe object and keep it alive in my GP service so that dataframe will not be defined each time when the GP service is called? (i.e. dataframe is defined when GP service is set up and destoryed when GP service is stopped). I am not sure whether arcpy contains function for defining some globel objects for GP service operation or not. If no, SOE (server object extensions) can do so? ... View more

I would like to use arcpy to add a specific layer in mxd and automatically label the feature with different colors according to its attributes. Even if I use the simple syntax lblClass.expression = "Function FindLabel ( [OBJECTID] ) FindLabel = [OBJECTID] End Function", label also cannot be shown. I search some papers about this and found that it may caused by "Advanced" setting on label expression. However, my layer is dynamically added in mxd but not pre-loaded in mxd. Does anyone know, 1)  Can I label the feature with different colors according to its attributes if i don't turn on "Advanced" setting on label expression (dont use If-then)? 2)  How can I turn on the "Advanced" label expression by using arcpy? As I know, there is no property of labelClass to turn on the "Advanced" mode. Any other alternative methods to do so? I tried to use arcpy.mapping.UpdateLayer but "Advanced" label expression can not be updated by other layers which have set the "Advanced" option. Thanks. ... View more

Hi, Does anyone know whether the arcpy includes the function like "Clip to Shape" shown in ArcMap (DataFrame right click > Data Frame Properties> Data Frame > Clip Option > Clip to Shape)? I just can know that the arcpyproduction includes the similar function "ClipDataFrametoGeometry". However, it is required Production Mapping Licence. It is strange that "Clip to Shape" is a built-in function of Arcmap but it does not include in arcpy. Thanks Calvin ... View more

Hi I would like to use a managed dll for ArcMap and background geoprocessing (64-bit). I registered the dll by using the methods described in 43712 - ESRIRegAsm.exe Error: Registration Failed. Could not load file or assembly​ and 40735 - Register function tools (DLL) for both Desktop and 64-bit Background Processing​. However, i got the problem in step 5 (ESRIRegAsm.exe C:\xxx\xxxx.dll /regfile:xx.reg). I found that ESRIRegAsm.exe cannot generate any register file (xx.reg) in 10.3 under win7(64-bit) but successfully generate in 10.2 under win server 2008(64-bit). I used the parameter ESRIRegAsm /e to get the error message but it just showed "Generation of reg file failed (/regfile option)." Did I get anything wrong for dll registration for 10.3 under win 7 (64-bit)? or It is a bug for 10.3? Thanks Calvin ... View more
