• Visual Studio 2008 (Pre-release) awkward syntax?

  How awkward is the syntax for directly using a foreach statement directly over linq query results: foreach (var x in from e in db.Employees where e.City == "Melbourne" select new {e.FirstName,e.LastName}) {    Console.WriteLine(x); }   a suggestion, yes but Im not sure that it covers the full range of possible expressions foreach (var e in db.Employees where e.City == "Melbourne") {    Console.WriteLine( new {e.FirstName,e.LastName} ); }   ...Show All

• Visual Studio Express Editions Bad Advice - Don't use Roxio

  In the manual install instructions for burning a CD, the instructions on the web http://msdn.microsoft.com/vstudio/express/support/install/default.aspx  page say "To install the image directly from your hard drive you will need to install 3rd party software that is capable of understanding *.img file extensions. Popular software programs like Roxio’s Easy Media Creator include a Disk Image Loader application that enables you to mount disc image files in a virtual drive as if they were physical discs in a physical drive" Well, I forked out AU $144 to purchase Roxio's easy media creator, and it doesn't understand what a .img file is ...Show All

• Visual Basic VB and OpenGL

  Now that I've worked with the very basics of DirectX with Visual Basic, I'd like to see how it's like with OpenGL. Though I can't find any up-to-date tutorials or anything about this.. Any suggestions Thanks in advance, Michel Hi, there are lots of tutorial using OpenGL, but the big problem is using OpenGL with VB. There is a lot of data marshalling to do, as OpenGL is unmanaged. All is not lost, see this link for an excellent C# framework: http://www.devdept.com/ I have this running with VB no problem, you can easily make a class lib to use in you VB project, there are a couple ...Show All

• Windows Forms 'System.Security.SecurityException' when running .exe file from other than developermachine

  I've developed a small console application that gathers systeminformation about the machine. I can run this from a shared network drive, and it works fine. But when i implement 2 more functions that writes a key to the registry and creates a desktop icon on the machine that runs the app, i get a System.Security.SecurityException. I have also made a .cmd file that copies the .exe file onto the user's c: and runs it from there, but i still get the same exception.. ! Any tips on how i can avoid this Here is the code that generates the error (i've found out that both the registry-writing & the desktop creation generates the same error): & ...Show All

• Smart Device Development Auto-generated Code

  Hey everyone, I have a VB2005 project with a SQL Mobile database. The database is rather large. I've created parameterized queries to load grids and selected the grid task to Generate Data Forms. I delete the New menu option and the editable form. I am just using the detail form that opens when a record in the grid is selected. My problem is that when I click on a record on the main grid during testing, it takes an extremely long time to open the detail form and populate the labels from the corresponding fields. When I originally did this in VB2003, I hand coded everything, and the searching and loading was much, much faster. I ...Show All

• SQL Server Script component as Destination - HasSideEffects?

  How to set 'HasSideEffects' property for any input column of a script component used as destination My Script component reads input, generates SQL update statements dynamically and fires them. There is no output. When executing, I get this error (which is self-explanatory). "Script Component" (1573) has been removed from the Data Flow task because its output is not used and its inputs have no side effects. If the component is required, then the HasSideEffects property on at least one of its inputs should be set to true, or its output should be connected to something. How do I get around this thanks, Nitesh Which build do you have ...Show All

• Smart Device Development Asynchronous I/O functions on CE

  Hi, I need to port a Windows desktop communication DLL to a PocketPC target. Unfortunately, it seems that CE doesn't support aynchronous call for the I/O function ReadFile, WriteFile and CreateFile but these functions were esential to my DLL. So, is there really no support for overlapped I/O methods on CE Is there another way to implement non-blocking read/write operations on serial ports or sockets Thx, Negyoshi. Overlapped is more efficient, and should take some space too. That should be the reason why MS did not implement on CE. But that discussion is not the topic. > Do you use message queues ...Show All
