• Visual C# Throw Exception gets unhandled error

  I am creating a multi-layered application using dlls' and want to throw any exception that occurs (and also create my own exceptions to throw) back to the originating code. When I try this though I get an error that the exception is unhandled. I am trying to handle it by just throwing it. This occurs at the first throw which is in class a catch clause. The following dll deals with database access. The code snippet is : class a{ public object ExecuteScalar( QueryBuilder QB){ object res = "" ; try { string sql = BuildSQL(QB); // connect to the database and run the query SqlCommand cmd = new SqlCommand (sql, DBConnections .SQLConn); DBConnections .SQLConn.Open(); res = cmd.ExecuteS ...Show All

• Visual Studio Team System "Get Latest Version" does not retrieve newly checked in files

  A source code file, which was referenced in a project file,was missing on my local hard drive. I asked a collegue to add that file to TFS source control. Then I used the command "get latest version" on the project but the file was not downloaded. I had to select the file in Source Control Explorer and use the "Get specific version" with "Force Get". Is this by design Hi Richard: The first thing that I would say is that not getting files that are in version control is not By Design. I think it is probably some type of timing issue or you got into a situation where the system thought you already had the file. Either way it seems that you got out of that state. If you have ...Show All

• Software Development for Windows Vista Writing only selected frames in AVI?

  Greetings, I'm trying to pass to file writer filter only selected frames from a stream. I have written a transform-in-place filter that passes through only those frames that I need, but file writer writes the same frame several times (instead of writing it only once and waiting for the new frame to arrive). How can I invalidate frame once it has been written so that it won't be written again Thank you in advance, Murom AVI files do not have a per-frame timestamp. They only support a fixed frame rate. So you cannot pick and choose when to write a frame. If you have started at 25fps, then you must keep 25 fps. MPEG-4 files do not have this limitation; nor do stream-based container formats such as mpeg-2 PS. G ...Show All

• .NET Development How can I get my asp.net application faster with .net CLR

  Hi gurus, how can I optimize any asp.net application's speed with the help of using CLR. What rules should follow to do that any articles or checklist is required Cheers Agha, Unfortunately there isnt a silver bullet that will help managed applications run faster. Performance Optimization is done on several levels, not just the CLR. Infact in my experience, 99% of the cases run fine with the default CLR settings. Is there a specific performance problem you are facing Here is a basic guide to some elementary ASP.NET perf tuning. http://samples.gotdotnet.com/quickstart/aspplus/doc/perftuning.aspx For GC/Memory tuning look up Maonis blog at http://blogs.msdn.com/maoni/ There is an interesti ...Show All

• Visual Basic passing variables between forms

  I am having serious issues trying to take data from one form and passing it to another form... I have a 3 form new employee application that gets information from the new employee in textboxes and then sends it to a database... my problem is that once i make an instance of the form: dim theFirstForm as new Form1... and dime theSecondForm as new Form2. i cant seem to figure out how to access it and store it in variables... so that on the third form i can access it and populate a database with all the information.

• SQL Server sp and applicatins

  We need to do an audit of all objects(sp, etc) in the database. Each object need to be validated if any apps use it. Then keep an updated way of knowing what sp is used by what application(a grid somewhere) Note: We have some sp's that are used by two or more application. any ideas That only works with insert, update, and delete.

• Game Technologies: DirectX, XNA, XACT, etc. Collision Detection With Bezier Curves

  Hi, I'm currently making a small 2D game in XNA Game Studio Express. It involves a player moving around a terrain and being able to collide with it. Nearly all the graphics and settings in my game are user generated so this allows for everything to be quite customisable. For collision detection the user specifies paths made of Bezier curves which are stored in a file. The game reads this file and stores a number of points on the curves in an array. The player is also made of Bezier curves that are converted into points: This shows how I want collision detection to happen; if any of the lines that make up the player intersect with any of the lines that make up the terrain, then a collision has occurred. Once a collision has occurred two t ...Show All

• SQL Server How to disable Export

  Hello, I am making a web application and I will show reports with the reportviewer, however the user can manage some parameters of the applicacion, the administrator can decide if he wants to allow the user to export or not export to PDF or XLS. Anyway, I want to enable or disable those options in the reportview dinamically! Is that possible I am going to take a guess based on 2 things you have said: "export to PDF or XLS". You don't mention other formats. "If I use Object o = info.GetValue(extension), then the object o is not null. " Is this an RDLC, not an RDL In which case what exactly is decorating a ServerReport going to buy you Either way, you can do what Brian said (set ReportView ...Show All

• .NET Development Asynchronous Sockets, BeginConnect

  I am trying to use the BeginConnect() method. Maybe I am not understanding it properly but I thought it would keep trying to connect to whatever host:port you asked it to until it connected (or times out maybe ). If this is the case then does anyone know how to change the timeout interval, or make it so it doesnt time out. I have an application that wants to keep polling a given host to see if its there, and if it is then connect to it. Is there a better way to do this if I am totally wrong on the BeginConnect stuff Any help would be greatly appreciated Thanks TcpClient client = new TcpClient(); public void TryConnect(IPAddress serverIP, serverPort) { this.client.BeginConnect(serverIP, serverPor ...Show All
