• Visual Studio Creating Delegate Types from Interface Methods

  Does the class designer offer any shortcuts for creating a delegate type based on an interface method There's no doubting that MSR Cambridge did a fine job designing generics, and I'm glad to see that they were commercialized with .NET 2.0. (I've been waiting for them for years!) Expressed in terms of generics, what I'm looking to do is: public delegate DelegateType<Interface.Foo> FooDelegateType; public static event FooDelegateType FooEvents; Specially, I want to avoid the CPM (copy-paste-modify) chore in which I copy a series of interface signatures into delegate type declara ...Show All

• SQL Server Nested Loops in the Control Flow

  I have a problem when using nested loops in my Control Flow. The package contains an outer Foreach Loop using the Foreach File Enumerator which in my test case will loop over two files found in a directory. Inside this loop is another Foreach Loop using the Foreach Nodelist Enumerator. Before entering the inner loop a variable, xpath, is set to a value that depends on the current file, i e /file[name = '@CurrentFileName']/content . The Nodelist Enumerator is set to use this variable as its OuterXPATHString. Now, this is what happens: First Iteration: The first file is found and the value of xpath = /file[name = 'test1.txt']/content. When ...Show All

• Windows Forms Form close button

  Anyone could help me how to disable the modeless and model form close button and disable the moving of the form. It would much more appreciate if anybody share your programming experience in .NET 1.1. 1. To hide the close button, use the property ControlBox = false. this will also hides the maximaize\minimaize buttons. 2. Another option is to handle FormClosing event like this: private void Form1_FormClosing( object sender, FormClosingEventArgs e) { if (e.CloseReason == CloseReason .UserClosing) { e.Cancel = true ; } }   ...Show All

• Smart Device Development Setting Up RDA

  I'm having trouble setting up RDA for data transfer between a CE 5.0 application and ( for now) Sql 2005 Developer Edition. On my development machine, I have IIS ( 5.1 ) configured for anonymous access. I ran Sqlcd30setupen.exe, then ran confwiz.exe to set up RDA. I configured a virtual RDA directory pointing to the original location of the sqlcesa30.dll (c:\Prog Files\MS SQL Server 2005 ME\Server\) Sql Server 2005 is configured with multiple users, all guesses at what the problem is. I have UID: Me Pwd: MyPassword UID: \\gtw001\IUSER_GTW001 UID:\NT AUTHORITY\System all having select permissions on the appropriate ...Show All

• Smart Device Development New to .net CF2 & PPC

  Howdy! I've done a bit of programming in the past and now am looking at making some stuff for PPCs. I downloaded the Emulator and ActiveSync, but have not managed to get them to sync together. Anyone know of any n00b guides for this I read in the doco to 'rightclick on the GUID'. I'm guessing this means 'rightclick on the emulator' but that brings up no menu for me. I'd also like suggestions on a free IDE and compiler. I'm thinking .Net Compact Framework 2 is the place for me to start. I'm not really a guru in any language altho I've programmed a handheld game in C (with a little C++ thrown in) and a small very simple application in J2ME. I ...Show All

Unfortunately the ReadXML doesn't provide you with any status as it loads, so you might go with the "marquee" styled progress bar (requires XP or above) that just cycles/loops.   -mark Program Manager Microsoft ...Show All

• Visual J# Help: how can I avoid the System.OutOfMemoryException?

  Dear All, A System.OutOfMemoryException always occurs in my program when the input data size becomes larger. Basically my program uses a recursive method to travel all paths in a graph. For example, the graph's configuration looks like this: three nodes A, B, and C. There is one edge between B and C, and the only thing that changes is the number of edges between A and B. When there are 2000 edges between A and B, my program works fine. But if I increase the number of edges to 3000 or more, the exception occurs. I suspect most memory is consumed by this recursive method. Yet, memory should be released whenever such a method returns. Is ...Show All
