• .NET Development Best Practice: Activity status

  I'm back again! For me this is a bit hard to grasp/tackle. My application has a UI and several other classes. I know that no class should interact with the other if its not needed, which is fine. I know about these things. If I have a class doing some work (not the UI), I want to be able to notify the UI of the status/activity that is going on in this work. Is it correct for me to say that I should create events which would be raised from this class, so that the UI will catch it and display the status to the user Obviously this "work" class knows nothing about the UI class, nor does it need to. All it needs to do is its work and then display the status of what its doing, wherever this status is displayed is none ...Show All

• Windows Forms generic contextmenustrip

  I have a treeview that when i right click on it a contextmenustrip is shown. Actually there are different types of nodes in the treeview and each of them should have its own choices in contextmenustrip. The question is how to manage that, contextmenustrip gets the list of related choices from each node so that when the user click on that choice appropriate function will be called. Take it to consideration that i want each node to do its tasks instead of treeview. I think it would be better to use something like propertyGrid instead ContextMenuStrip , but im wondering is there any way to handle the propertyGrid so that it just has one column with customize display. imagine a propertyGrid with a bottun placed on it,( or a p ...Show All

• Software Development for Windows Vista SetupIterateCabinet failing from Custom Action .dll

  I use Visual Studio 2005 to deploy my application. I have a Custom Action .dll that's called during the Install phase. (The entry point is the standard Install( MSIHANDLE ).) I'm installing a .CAB file and am calling SetupIterateCabinet() from this Custom Action .dll and it is returning ERROR_ACCESS_DENIED. Appears as though Custom Action .dll's are not run with the UAC elevated privileges of the .msi file. I tried adding a .manifest to give the .dll elevated privileges, but then Windows XP barks that there is an unrecognized token. I need this .msi file to run under both Windows XP, Windows 2000, and Windows Vista. Because this is a Custom Action .dll there is no way I can wrap the function in a COM object and call it with ...Show All

• .NET Development Why doesn't System.Array have an indexer?

  I'm probably missing something here, because my all of my searches came up with nothing. It seems only natural for Array to have an indexer. But instead, we have to use Get/Set Value(). Why is that Interesting idea. How about this: public class Base { private object[] values = { 1, 2, 3 }; public object this[int index] { get { return values[index]; } set { values[index] = value; } } } public class Derived : Base { public new int this[int index] { get { return (int)base[index]; } set { base[index] = value; } } } public static class Test { public static void Run() { Derived d = new Derived(); int i = d[0]; d[0]++; Base b = (Base)d; object o = b[0]; } } It ...Show All

• SQL Server Grouping Data Problem

  Hello all I am using SQL Server 2000. I have a table of over 1 million accounting transactions. I need to be able to remove all items that have contra items. e.g debit ￡100 - credit ￡100 - debit of ￡125 ( I only want to see the debit of ￡125) I can achieve this in MS Access by grouping the key fields, suming the value fields and using the First() or Last() command for columns that I need to display but not group.
