• Visual C# Cannot implicitly convert type 'Microsoft.Win32.SafeHandles.SafeWaitHandle' to 'System.IntPtr'

  I am now tring to modify some code developed before by someone else, and when I build it, the error message will be shown: 'System.Threading.WaitHandle.Handle' is obsolete: 'Use the SafeWaitHandle property instead.' And the source code related to this warning is: wo.hEvent = writeEvent.Handle; Then, I change it to: wo.hEvent = writeEvent.SafeWaitHandle; However, when I try building again, some error shows: Cannot implicitly convert type 'Microsoft.Win32.SafeHandles.SafeWaitHandle' to 'System.IntPtr' As I am still very new to C#, I do not understand that clearly...

  Will DDS files that are created for PC work with the 360 is there not some subtle difference between the two or is this something that will be patched up via the XNA runtimes on the 360 upon asset loading I don't work for MS either, but I know for a fact the block orders differ, unless there's some mode to mark them as linear, which would be a performance hit (of which might not matter), but would still would be good to know before hand. ...Show All

• Visual Studio Express Editions startIndex problem when unable to connect to the internet

  I've been creating a program that will restart my modem so I can get a new IP whenever it changes to an IP out of the range I want. For getting the IP I used a ready-code that catches the content of a webpage into a textbox. Then I used a System.IO.StringReader to start getting the content of the textbox after the ": ", which is when the IP comes. Here it is: Public Function getIPstring() As String 'This creates the filestream and streamreader that is used to read the source Dim SR As New System.IO.StringReader(TextBox1.Text) 'Here is where we start looking for the ip. 'This puts the entire file into a string Dim entirefile As String = SR.ReadToEnd 'This gets the starting position o ...Show All

When i run this report in Crystal Reports XI:R2 the date displays as dd/mm/yyyy But when the report is run from an ASP page only that formula date changes to mm/dd/yyyy   Any Ideas why it does this Have you checked the "regional and language options" settings in Control Panel (the icon that looks like a globe) Go to "Regional Options" tab -> "Customize" button -> "Date" tab -> and "Short Date Time" format. You might have different datetime format settings for your local machine and the server machine running ASP pages ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Playing In Traffic game sample

  Here is a simple game called "Playing In Traffic", based on an episode of an animation series (which you can see here ) . It was our first xna game (with lots of orphaned experiments and general ugliness), but the source is included anyway for anyone who may find it useful. We will be adding more to the entry page as time goes on, as well as updates to an swf to xna converter in progress now. You can download the game and source here . 2007 should be a great year for the Xbox and consequently XNA, very much looking forward to it. Hope it is a good one for you as well! Cheers, Robin downloaded and played for a while, then my girlfriend wanted a game I don't own a 360, so I modded the UpdateKeyboard() cod ...Show All

• Visual Studio Express Editions Serial Port multithreading

  Is it possible for YourCOMPort.BytesToRead and YourCOMPort.DataReceived to change while the subroutine, which handles YourCOMPort.DataReceived is still in progress At very high data rates, the data may come in so fast that for example while previous data is being send to display by means of BeginInvoke new data are received. Depending on how Windows and .NET is build this may or may not course BytesToRead to change and/or a new DataReceived event, while the routine which handles this event is still in progress. If events are just boolean signals - not a queue - there may be a risk that if a new event occur while the subroutine, which handles this event is still in progress, the subroutine will not be reactivated (event cleared at exit). ...Show All

• Windows Forms Black label and persistent wait cursor

  Hi everyone! I have a problem with a GUI, which has a label and a panel. When executing, the label is always black and the cursor is wait cursor (until the program ends). Moreover, in the Windows XP toolbar doesn't appear the label of the running program until it ends. Could this problem be due to the fact that the gui class even has the responsibility to update the graphics of the panel Maybe it is better to delegate this task to another class Thanks while (goal > clock()); // insert a body and put Application.DoEvents() ...Show All
