Get Active Sheet Set Properties

drobertsY4GL3 — Tue, 20 Oct 2020 22:21:11 GMT

In a similar post, the sheet set IAcSMComponent was cast to an AcSmSheet to access the sheet set properties GetName() GetNumber() etc. In my case it returns a NullReferenceException. I suspect this is because the component "Deck" is a subset.

How can I get access to the sheets inside of "Deck" to get the sheet set properties?

public void GetSheetSetProperties() { var sheetSetManager = new AcSmSheetSetMgr(); var databaseEnum = sheetSetManager.GetDatabaseEnumerator(); // Get the first database in list. AcSmDatabase database = databaseEnum.Next(); database.LockDb(database); // Get the sheet set in the database. AcSmSheetSet sheetSet = database.GetSheetSet(); var sheetEnum = sheetSet.GetSheetEnumerator(); // This gets the main component named "Deck" in the example tree. var component = sheetEnum.Next(); #region DoesNotWork // Cast component to dummy sheet to get properties. var dummySheet = component as AcSmSheet; // Creates: System.NullReferenceException: 'Object reference not set to an instance of an object.' string ssName = dummySheet.GetName(); string ssNumber = dummySheet.GetNumber(); #endregion // TODO: Get the actual sheets i.e. the sheets under "Deck" }

Thank you.

See https://blog.jtbworld.com/2005/01/sheet-set-manager-api-code-sample-for.html for how the logic is.

Thanks Jimmy.

Looking at you're example, my suspicion was right. I needed to drill down to the AcSmSubset to get the actual sheet properties. What I was really trying to access however was the sheet set project info and thought perhaps I could use the sheets to do it. Is there another way?

Below is the working code for getting subset sheets:

public void GetSheetSetProperties() { var sheetSetManager = new AcSmSheetSetMgr(); var databaseEnum = sheetSetManager.GetDatabaseEnumerator(); // Get the first database in list. AcSmDatabase database = databaseEnum.Next(); //database.LockDb(database); // Get the sheet set in the database. AcSmSheetSet sheetSet = database.GetSheetSet(); var sheetEnum = sheetSet.GetSheetEnumerator(); var sheet = new AcSmSheet(); string sheetSetName = ""; string sheetSetNumber = ""; bool sheetFound = false; // Get sheet from component or subcomponents. var component = sheetEnum.Next(); while (component != null && sheetFound != true) { if (component.GetTypeName() == "AcSmSheet") { sheet = component as AcSmSheet; sheetFound = true; } else if (component.GetTypeName() == "AcSmSubset") { var subset = component as AcSmSubset; var subComponent = subset.GetSheetEnumerator().Next(); while (subComponent != null && sheetFound != true) { if (subComponent.GetTypeName() == "AcSmSheet") { sheet = subComponent as AcSmSheet; sheetFound = true; sheetSetName = sheet.GetName(); sheetSetNumber = sheet.GetNumber(); } subComponent = subset.GetSheetEnumerator().Next(); } } component = sheetEnum.Next(); } }

Thank you for the posts.

They work great for accessing custom properties.

How does one access the "regular" properties? In particular I am after the ones in the Project Control Section i.e. project number, project name.

Custom Property snippet:

string propName = ""; AcSmCustomPropertyValue propValue; // Get custom propery enumerator from sheet set. var propEnum = sheetSet.GetCustomPropertyBag().GetPropertyEnumerator(); propEnum.Next(out propName, out propValue); while (propName != null) { propEnum.Next(out propName, out propValue); }

The root of the problem I discovered is that the methods I needed are missing.

Please see the breakout post below:
