Hi everyone, I have a dozen mxds that I run during the night from Windows Task Scheduler. They start ArcMap automatically, run code to process some data and then shut down. Now I need to convert these from VBA to C# since VBA will no longer be supported at ArcGIS 10 and I am lost on how to start ArcMap, run code and lastly shut down ArcMap programmatically. I've seen a few post both here and the old forms on how to start ArcMap automatically but nothing on how to run code at start up. In the VBA code, there is code in the MxDocument_OpenDocument function to run the entire thing including shutdown. But in a standalone C# application, there is no such thing as MxDocument_OpenDocument so how do I get my code to run at start up? Thanks, Carlos ... View more

Hi everyone, From an existing custom menu on a custom toolbar called Data, I am trying to create a structure like this and do it all on the fly at run time: Menu1     |     |----Submenu1     |           |----Command1     |           |----Command2     |----Submenu2     |           |----Command1     |           |----Command2     |----Submenu3 Thanks to LOTS of help from the forums, I have been able to create the menus and sub-menus on the fly with no problems but now I am stuct trying to do the same with the commands. In the example above, if I add an existing ArcMap or custom command previously created to Command1 in Submenu1, the code works fine. If I try to add a new instance of an existing command, the code crashes trying to give it a new UID with an error of, "Value does not fall within the expected range."         internal static void PopulateDataSubMenu(ICommandBar pMenu, string entitySetName)         {             try             {                 OleDbConnection dataConnection = new OleDbConnection();                 dataConnection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +                                                   "Data Source=\\\\ad.sfwmd.gov\\dfsroot\\data\\err_gis\\applications\\dev\\mdb\\rimGISLibDatabase\\mdb\\GISLIBFeaterClassName1.mdb";                 dataConnection.Open();                 OleDbCommand dataCommand = new OleDbCommand();                 dataCommand.Connection = dataConnection;                 dataCommand.CommandText = "SELECT distinct(Order1ClassName) " +                                           "FROM qryorder1 " +                                           "WHERE Order1SetName = '" + entitySetName + "'";                 OleDbDataReader dataReader = dataCommand.ExecuteReader();                 object idx = 0;                 int counter = 0;                 while (dataReader.Read())                 {                     string className = dataReader.GetString(0);                     idx = counter;                     CmdTest2 cmdTest3 = new CmdTest2(entitySetName + " - " + className, entitySetName, className);                     UID uid = new UIDClass();                     uid.Value = cmdTest3;    <---CRASH HERE                           pMenu.Add(uid, ref idx);                     counter++;                 }                 dataReader.Close();                 dataConnection.Close();             }             catch (Exception ex)             {                 MessageBox.Show(ex.Message);             }         } In the code above, CmdTest2 is a command created using the ESRI BaseCommand template and I am passing it a couple of parameters so that I can use the same command to load different datasets. Does anyone know how what is going on and how I can fix this? Thanks, Carlos ... View more

Hi everyone, I have a form which has a listbox on it displaying all lakes in the state so the user can select which one they want to load and zoom to. On the InitializeComponent(); section of a C# form, I set the mouse cursor to an hourglass with this code: IMouseCursor pMouseCursor = new MouseCursorClass(); pMouseCursor.SetCursor(2); Right after this line, the code calls another method which queries the lakes layer, puts all of the names into an array and returns this to the listbox for display. As soon as the code goes to the method that does the query, the cursor returns to the pointer instead of staying an hourglass. Trying to set the cursor back to hourglass inside of this query method has no effect. This query can sometimes take up to a minute to run depending on network traffic so I definitely want to show the user that code is running and not have them think the program is locked up. Any ideas on how to fix this? Thanks, Carlos ... View more

Hi everyone, My boss would like to automate the creation of menus, commands and forms dynamically in C#. We have a custom toolbar with lots of menus and submenus on them. On these, there are commands, tools, etc. My boss would like to read a database table and create a new menu for each row in the table, i.e. buildings, roads, canals, etc. Each one of these menus would have either submenus, forms, commands or tools on it. So far, I have been able to manually create a generic form and populate it (add checkbox controls) with different types of data. My problem now is creating the menus themselves dynamically every time the toolbar is displayed. I have experimented with IMenuDef but from what I can see, you must know how many options (submenus) you are going to have and I will not know that at runtime. My boss wants to be able to edit the database table and have the new menus, forms, tools, etc. magically appear on the toolbar. I've read tons of postings on the forums and I get the suspicion that it is possible to do it, but I cannot figure it out. Any help is greatly appreciated! Carlos ... View more

Hi everyone, I am trying to write some generic C# code that will identify the data source of any possible layer a user might add (Coverage, Shapefile, table, etc.). I thought I had the solution when I found the ESRI IDataLayer Example and this works well in VB6 or VBA. When I convert it to C# however, it fails for layers of type SDE Raster, Raster Catalog and File System Raster. pDatasetName becomes null with these data types and the code crashes. So far in my testing I have determined that I can use IDataLayer2::DataSourceName::NameString for data types of: File System Raster, SDE Raster, ArcGIS Image Service, Raster Catalog, Coverage Feature Class and IDatasetName2::Name for data types of: Shapefile Feature Class, Personal Geodatabase Feature Class, File Geodatabase Feature Class. While this approach works, I do not want to have to write code for every possibility, i.e. if (pLayer is IFeatureLayer) {     do something } else if (pLayer is IRasterLayer) {     do something }             IMxDocument pMxDocument = (IMxDocument)m_application.Document;             IMap pMap = pMxDocument.FocusMap;             ILayer pLayer = pMap.get_Layer(0) as ILayer;             IDataLayer2 pDataLayer = pLayer as IDataLayer2;             IDatasetName2 pDatasetName = pDataLayer.DataSourceName as IDatasetName2;             IWorkspaceName pWorkspaceName = pDatasetName.WorkspaceName;             string name = string.Empty;             if (pDatasetName is IFeatureClassName)             {                 IFeatureClassName pFeatureClassName = pDatasetName as IFeatureClassName;                 if (pFeatureClassName.FeatureDatasetName != null)                 {                     name = pFeatureClassName.FeatureDatasetName.Name;                 }             }             MessageBox.Show("Path: " + pWorkspaceName.PathName);             MessageBox.Show("Feature Dataset: " + name);             MessageBox.Show("Feature Class/Dataset: " + pDatasetName.Name); ...
