• Visual Studio Rules in DSL Tools V1

  Hello I tried to implement a mechanism to do some action when I add an element on the diagram. In an older thread, I read about Rules. I created a Rule which inherits from AddRule and added some code in the overwritten ElementAdded(...) method. To register this rule, I created a partial class named "GeneratedMetaModelTypes" and added the corresponding type. But it doesn't work, I also couldnt find any other partial class GeneratedMetaModelTypes... Is this not supported anymore in Version 1 Are there other possibilities to intercept the adding of an element Thanks for your reply! Best regards Christian Here is a sample from my model. I have two Rules [RuleOn(typeof(Connector), FireTime = TimeToFire.TopLevelCommit)] ...Show All

• Visual Studio 2008 (Pre-release) video example not working

• Visual C# How to make global data thread safe ? Please Help...

  Hi friends, I seem to be stuck in a peculiar problem. I have a public static class with public static members (different array lists). The members are thus global in nature and accessible across the namespace. I have a worker function which is called asynchronously (so that there are several instances running per second) and which reads the different global members at different points of execution (not the entire set at any one point). I have a writer function which is used to set the global members and this is the only one in the application writing to these variables. It will write the entire set of globals when given control through a GUI event. I need a mechanism where if one instance of worker function is accessing any ...Show All
