• Windows Live Developer Forums Polyline Craziness

  I am working on a mapping project that allows the user to draw polylines. It all seems to work when the user clicks points of the polyline. From there I save the gps coords to a database. When I then retrieve the coordinates and display the polyline it does crazy things. It initially displays correctly but when zooming in, the line sometimes disappears, or draws in incorrect locations. If it does draw in incorrect locations and you pan, the polyline constantly moves. Can anyone please help, this problem is starting to drive me crazy. I have included "some" of my code. function loadMap() { mapDiv = document.getElementById( "myMap" ); new VEMap( 'myMap' ); map.LoadMap(); map.HideDashboard(); ...Show All

• SQL Server SOLUTION! - VB.NET 2005 Express and SQL Server 2005 - NOT saving updates to DB - SOLUTION!

  VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION! ----------------------------------- The following article is bogus and confusing: How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy' http://msdn2.microsoft.com/en-us/library/ms246989.aspx You must manually copy the database file to the output directory AFTER setting 'Copy to Output Directory' to 'Do not copy'. Do not copy The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file ...Show All

• Visual C# Sound question

  One last question: Unlike many other people who like to know about adding a sound file (.wav, .mp3), I would like to know how to get my program to just make that *lovely* beep sound that I was all to found of in QBASIC. I would like to know how to get just a simple beep when the user clicks a wrong button. Since I am so old school and out of touch with C#, I can only provide an example of it in QBASIC CLS BEEP END Any simple way of doing this in C# lol QBASIC -> C# in .NET 2.0 there is a soundplayer class which you can play sounds, including system default ones but would play on the computer speakers than the computer itself. Would this be suitable System.Media.SystemSounds.Beep.Play(); to get it to play the beep ...Show All

• SQL Server Optins of trailing Database change in sql server

  Hi All, I am in need of some option using which i can trail the changes made to my database. Specially i want to track all the DDL and DMl changes.

• Game Technologies: DirectX, XNA, XACT, etc. Cross-Platforming

  Code-wise how simple is it to make a game in XNA that compiles on PC then compile it for 360 And how will devs be able to add or remove features between both WITHOUT needing to recode are their methods in the framework that will allow me to execute certain code depending on the platform ex. Control scheme, obviously I can't play a game that requires a mouse on the 360, and I cant play a game that requires a controller on the PC. Or does XInput have actively configurable schemes availalbe "I cant play a game that requires a controller on the PC" Actually you can. The wired 360 controller works just fine on the PC. I'm in the process of examing XAct and XInput now using the August SDK. I'm not sure how different it'll be ...Show All

• SQL Server Yearly, monthly... basis report based on the parameter values

  Hi guys, I am created a bar chart report. The x-axis value of this chart is a timestamp(datetime) field of a dimension. Thousands of records are inserted in to this field everyday, as a result, I will have the timestamp information every second or minute. So here is the thing, If I want to present last month data in the bar chart(x-axis), the chart can not accomodate all the data and it doesn't look good to present a data in every second or minute. So I want to present the data on yearly, monthly, weekly, daily or hourly basis based on the StartDate and EndDate parameters value provided by the user. Any idea is appreciated.

• .NET Development provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

  This is my first application I'm building with Visual Studio 2005. I have a very simple piece of code: string dbSource = "Data Source=WMCCWKTBSWZ90EZ;Initial Catalog=Aptment;Integrated Security=True" ; SqlConnection con = new SqlConnection (dbSource); con.Open(); and it fails with the error: Error reading list of names. An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) WMCCWKTBSWZ90E is my local SQL Server. I've used it thousands of times. I ha ...Show All

• Windows Forms DataGridView: One double click calls both CellMouseClick and CellMouseDoubleClick

  Now I see that my question was very badly writen so I re-write it. I am writing in C#. I have a DataGridView and two functions: One to handle the CellMouseClick event and one to handle the CellMouseDoubleClick event. The problem is that if the user double click a cell, BOTH events are called! First the CellMouseClick and then the CellMouseDoubleClick directly after. They are both called by the VERY SAME double click! It would have helped if I at least could tell if the "CellMouseClick" is caused of a double click or a single click. Anyone that knows how Isn't it alltogether a bug I do not think that a CellMouseClick should be raised by a double click at all. Thanks in advance, Keren PS: This is a car booking system. A single click on a bo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Generate random numbers for every class instance

  I'm trying out some AI techniques but I'm having a problem generating a TRULY random number. I create 20 instances of an ant class that should move and change directions on a random basis. They are doing that, but all in unison instead of each changing directions at different times. Its like synchronized ants. Anyone know how to create a truly random number each time the ants use this method Random r = new Random (); if (r.Next(100) < 5) ant.Speed = new Microsoft.Xna.Framework. Vector3 (-ant.Speed.X, ant.Speed.Y, ant.Speed.Z); if (r.Next(500) < 2) ant.Speed = new Microsoft.Xna.Framework. Vector3 (ant.Speed.X, -ant.Speed.Y, ant.Speed.Z); Thanks kindly, George.

• .NET Development Thread scheduling problem: (apparent) violation of "wait on event" mechanism between /CLR processes

  Out of all the available forums, this one seems to be the most appropriate for this issue. This certainly is a .Net-related problem because I have done this successfully in the past with native applications (using VC++ 6.0). I am currently using VC++ 2005 with the latest .Net on an up-to-date Windows 2000 computer with 512MB of RAM. The failure is observed with high-probability under low-memory conditions: after running two instances of the Studio (so I don't have to keep swapping the solutions when I want to consult the code), but only one debugger session (the other process is running as an executable), and the 2005 SQL Express server, I'm left with a commit charge of around 700MB, i.e., some processes are swapped to virtual memory.

• .NET Development String concatenation optimized for avg. incoming packet size

  Hi, I'm currently working on a socket server that handles incoming ASCII encoded strings and I want to optimize the concatenation and framing of the incoming strings. Messages are stored in a buffer until message boundary is detected and released for processing. So, what I'm basically wondering is, if it's of any benifit to use a StringBuilder for the concatenation of the incoming string or if I can simply concatenate strings with str += "incomingstring"; My thinking is that StringBuilder doesn't add much benefit because PPPoE MTU is at 1492 and my messages have varying lengths from 100 to 400 bytes, which "SHOULD" mean that I ususally get the whole message per incoming packet. Am I right with this assumption ...Show All
