• Davids Learning Delegates and events

  Hi, I have been playing around trying to get an understanding of delegates and events - I would like to know if there is any difference between how the following 2 lines of code function ie: public delegate void NotifyFrm1 ( Object sender, ValueUpdatedEventArgs e); public static event NotifyFrm1 NotifyFrm1Action; as compared to: public delegate void NotifyFrm1 ( Object sender, ValueUpdatedEventArgs e); public static NotifyFrm1 NotifyFrm1Action; I get exactly the same results by ommitting the word event. thanks -Barb Thanks for the replies I think that is what I was looking for - I don't have any specific code that ...Show All

• DMAR330 Help required to solve circular dependency problem in vb2005

  I am working on an application design that requires two projects to cross reference each other. I found the excellent Formfactory / Interface example/solution (listed below) on this forum. Unfortunately I am not C# literate. I understand and appreciate the method, but my attempt to convert it into vb2005.net has been defeated by the C# syntax. I would greatly appreciate someone (multilingual) providing a translation into vb2005.net Here is the C# solution: The pattern to solve this is abstract class factory , together with the singleton pattern. What you have to do is the make a classfactory for the forms . This classfactory you can place in your main program, which anyway MUST reference your assemblies, thus it w ...Show All

• Sean Fuller Class accessibility?

  Ok, lets say I make a new project in VS05. I create a button named button1 on a form named form1. Now I create another file and another class (Right Click, Add, Item... C# class). Now I am in another class in another file, but if I do "form1.BackColor" it doesnt work. I cant access the button either. I can also make a variable public int test = 34; Cant access it outside the form1 class either. I tried a lot of things (yes, including putting "public" keywords everywhere) but it wont work.

• re infecta GETTING MORE THAN ONE INTERFACES...

  Hi All, I am not familiar with Traffic Control API yet. I was able to compile and run the code I created using Visual C++. The problems are the following: (1) There're two interfaces enabled (3Com EtherLink XL 10/100 PCI and Intel(R) PRO/1000 MT). When I call TcEnumerateInterfaces, my program only gets information about the first one. If I disable that one, the program gets the second one. Also, tcmon.exe recognizes both interfaces. The code is the following: TC_IFC_DESCRIPTOR InterfaceBuffer[20]; PTC_IFC_DESCRIPTOR pInterfaceBuffer = &InterfaceBuffer[0]; ULONG BufferSize = 20 * sizeof(TC_IFC_DESCRIPTOR); result = TcEnumerateInterfaces(ClientHandle, &BufferSize, pInterfaceBuffer); Question (1 ...Show All
