A: Check for the following reasons. 1. If there is a small question mark in front of the layer in the layer manager, it indicates that you need to re-specify the dataset for the layer. 2. Whether the maximum and minimum visible scales have been specified for the layer. If yes, the layer will not display at a map scale that is not within the specified scale range.

Set the layer's maximum and minimum visible heights and distances with in the Layer Properties window.4. Check the performance of graphics.5. Use the latest graphics card driver.
08 July,2019 iDesktopA: IT is recommended that you use the Partly Refresh function from the Settings dropdown list in the Browse group under the Map tab.
08 July,2019 iDesktopA: 1. Create an overview for the mosaic dataset, check to remove the NoValue overlap portion, and input the determined value for the NoValue data, so that correct values will display when no value areas and areas with values overlap after the overview is constructed.2. If there are still overlaps, you need to set No Value and transparently display the No Value specified. Meanwhile, you need to check the Draw by file, so that correct values will display when no value areas and areas with values o…
08 July,2019 iDesktopA: The absolute path is stored for the image path in the mosaic dataset. When the path changes due to the copying operation or some other reasons, you can right click the mosaic dataset to designate the path again.
08 July,2019 iDesktopA: During multi-version cache generation, the same cache name and the same database name must be used in the cache generation settings; otherwise, it will fail. You only need to set different version names to distinguish between different versions.
08 July,2019 iDesktopA: Firstly, ArcMap needs to use the ST_Geometry storage format while creating features. Secondly, the user to create the OracleSpatial datasource must be consistent with the user to create the SDE database.
08 July,2019 iDesktopA: For the UDB and Oracl datasources you can use the expression substr(field_name,4). For the sqlServer dataource, you can use the expression SUBSTRING(field_name,4,len(field_name)-3) to remove the first three bytes.1. Are there any limits to length of the name of the dataset created in the Oracle datasource with SuperMap iDesktop 7C?A: The name of the dataset cannot exceed 30 bytes. Because of the naming rules of table names in the database, the number of letters cannot exceed 30.
08 July,2019 iDesktopA: While exporting the CAD dataset into a dwg file, you need to check the Export Extended Fields and Export Extension Records options. Similarly, while importing the data, you need to check the Export Extended Fields and Export Extension Records options.
08 July,2019 iDesktopA: While saving the workspace, the program will automatically save a hidden workspace file with the name of“~[0]+Workspace Name”. You can find the workspace file and the file is the previously saved workspace.
08 July,2019 iDesktopA: It is caused by the lack of libeay32.dll and ssleay32.dll. The decompressed version of mongoDB does not have these two libraries as the installed version. You can copy the two missing libraries directly from the installed version to the decompressed version.
08 July,2019 iDesktopA: Currently, the CAD data only supports the Rectangular and Offset registration methods, which require two pairs of control points. To employ more control points to enhance the precision, you need to covert the CAD dataset into single datasets first, and then use batch registration to perform registration with more control points.
08 July,2019 iDesktopA: After modifying the attributes of the Recordset, data in the attribute table ITabularControl cannot refresh automatically. You need to use tabularControl.Recordset = recordset to specify data again.
08 July,2019 iDesktopA: Find SuperMap.xml under the bin folder of the installation path, and find the CustomDPIEnable node in the SuperMap.xml file. Control whether to enable the user-defined DPI values with the value of true or false, with true indicating enabling the user-defined DIP values and false indicating disabling the user-defined DPI values. The default is true.Custom DPI value in the horizontal direction, with the default value 96.Custom DPI value in the vertical direction, with the default value 96.The t…
08 July,2019 iDesktopA: If You add a textbox control in the layout, there will be the property of ‘onAction=”DesktopPlugin1.MyCtrlActionTextBox”’. When needed, you can use ‘ITextBox textbox = SuperMap.Desktop.Application.ActiveApplication.MainForm.RibbonManager[typeof(MyCtrlActionTextBox)] as ITextBox;’to acquire the textbox control and the value of the textbox.
08 July,2019 iDesktopA: If you add a textbox control in the layout, the system will enter the MainForm_Loaded method of the DesktopPlugin.cs class (the DesktopPlugin.cs class is created while creating the plugin, and its name is identical to that of the plugin) after the launching of the desktop. You can acquire the textbox control in the method and add the TextChanged event for the control.
08 July,2019 iDesktopA: There are some rules for connecting fields while constructing the expression for thematic maps. For the UDB file datasource, you need to use ‘|’to connect two fields. For the oracle and sql server datasources, you can use ‘+’ to connect two fields. If the fields connected are now string fields, you need to convert the fields with the Str function to convert them into string fields first, Name + Str(SMID) for instance.
08 July,2019 iDesktopA: 1. Firstly, you need to acquire the Layer Manager:layersControlManager=SuperMap.Desktop.Application.ActiveApplication.MainForm.DockBarManager[typeof(LayersControlManager)].Control as LayersControlManager;2. Then, refresh the layer:layersControlManager.LayersTree.RefreshNod(layersControlManager.LayersTree.FindNode(layer)).
08 July,2019 iDesktopA: Considering the file-type datasource is exclusive, you cannot use the database in iDesktop and iServer at the same time. If you want to change the map with iDesktop, you need to close iServer first. After the modification of the data, you can save the workspace and close iDesktop, and then you can start iServer to make the changes take effect automatically.
08 July,2019 iDesktopA: You can use the Append function to append records of the three datasets to a single CAD dataset, and then implement the export operation.
