• .NET Development Sql Connection Hang

  Hi, I am using .NET 2 (beta2) and are having problems with using a SqlConnection. I have created a test application that opens a sql connections, gets some basic data and then closes the connection. When i run this application as the administrator it works fine.  However if i run the application as a standard user the application hangs indefinatly on SqlConnection.Open(). I dont get any time out or any exceptions.  It just hangs there. I am using SQL Authentication. I have tested this on many computers and the same happens. My main issue is getting this to work on Windows2000 Server (Sp4). thanks Arran   ...Show All

• Visual Studio Express Editions Where to declare variables?

  I apologize if this has come up before, but I'm new to this forum. I have been programming for almost 20 years, in QuickBASIC, Visual Basic and now VB Express, but I don't do a lot of programming, and the stuff I write is very basic (no pun intended). My typical program consists of a few screens where the user enters data, hits a continue button, then that screen goes away and another screen comes up, either to enter more data or to display results.  Very simple stuff, but I'm having a really hard time getting started in VB Express, even though I've done a lot of searching and reading.  I feel kind of like I have a new car ma ...Show All

• .NET Development FTP application problem

  Hi, I've noticed in other FTP applications that they are able to retrieve a remote file list with other attributes concerning the files, such as size, date modified etc. All this quite quickly. Does anyone know how this is done. I am able to send an FTP command to get a file list but then to get the size information I am sending an FTP command for each file. I'm putting everything in a listview control and obviously this is taking some time. Compared to other FTP software mine isn't really living up speed wise. thanks for any help, Chris Hi Sean, Thanks for your answer. I have tried t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. (C++) DXUT & ID3DXMesh not rendering. Also crash in dxutenum.

  Hi, I was reading over the DX documentation for C++ and came across the DXUT framework. Thus, I gave it a try and whipped up an example using their VS.NET project installer. The example is basically the mesh tutorial. The problem is that the mesh does not render on screen. I have played with  many parameters such as the view matrix and far clipping plane, however, nothing has prevailed. Also, the solution compiles with no errors/warnings. However, the program does crash. I went through the debugger and it throws an Unhandled exception at 0x0044d08b in demo.exe: 0xC0000005: Access violation reading location 0x00000009 when a poi ...Show All

• Visual Studio 2008 (Pre-release) ... like in Ruby

  Is it possible to extend int (simple types) to be able do something like in this code, written in Ruby 3.times { print "X " } Yeah, I understand.  But what real world scenario would involve doing an operation on a literal value   I'm not picking on the feature, but rather asking a theoretic question. Is the ability to do it against a literal just a "you get it for free anyway" side effect of type extensions or is there a scenario where someone would really want to do this   Brian ...Show All

• .NET Development Email not being sent from IIS 6 Virtual SMTP server

  Wrote a vb.net console app (framework 2.0) that sends email to an smtp server. Got the app working but now the email just sits in the SMTP queue and never actually gets sent. The size of the app in the SMTP queue is appropriate so I know the app worked, the attachments got attached, and the email got to my SMTP server okay. My question is why does it just sit in the SMTP queue and not go anywhere I don't know that much about SMTP servers so any leads or ideas would be appreciated. I installed and configured the SMTP virtual server and I think it is configured correctly but I am not sure. Thanks Steve Wells There are ...Show All

• Visual C++ Overriding IEnumerator<T>.Current and IEnumerator.Current

  I am trying to implement a collection in C++ deriving it from ::System::Collections::Generic::IList<T>. I am almost done but I am stuck on the following problem in the implementation of the enumerator: - the enumerator is derived from ::System::Collections::Generic::IEnumerator<T> - since IEnumerator<T> derives from IEnumerator we must implement IEnumerator<T>::Current returning a 'T' and IEnumerator::Current returning an 'Object' My question is: how to explicitly override two properties coming from 2 distinct base interfaces and having the same name I tried various combinations without success. The syntax for expl ...Show All

• Windows Forms Pencil glyph not displayed when row dirty

  When editing a cell on a DataGridView, the pencil glyph is shown only as long as the focus remains in the cell being edited. It disappears when moving to another cell in the same row. This is inconsistent with what described in the reference documentation that states that the propery IsCurrentRowDirty " returns true when the pencil glyph is displayed in the row". Even worse, this goes against normal user expectations leading to believe that the modified cell has been commited to the data source, when infact it has been not. How can I fix it Thanks Luca ...Show All
