• Visual Studio Express Editions after doing a division the value becomes zero (i think because of an endless numbers of decimals

  HP and MaxHP start each out with 999999, but once the HP gets changed to for example 999253 label1.text shows 0(it should be 99 -> (999253 / 999999)*100 = 99,9253and so on, can someone help me out pls hmm while typing this and seeing on the calculator that there is an endless number of decimals -> is this the prob so is there a way to make it a round number (100 instead of 99,9253and so on) This is my code: private void hPLabel3_TextChanged( object sender, EventArgs e) { int HP = Convert .ToInt32( this .hPLabel3.Text); int MaxHP = Convert .ToInt32( this .hPLabel4.Text); int Procent = (HP / MaxHP) * 100; label1.Text = Convert .ToString(Procent); HealthBar2.Image = Image .FromFile( &q ...Show All

• .NET Development SerialPort DataReceived Timeout?

  I'd like to get better control over when DataReceived are generated while using System.IO.Ports.SerialPort. In particular, I want to be able to control the timeout behavior. This can be done using SetCommTimeouts() when writing to the Win32 API but so far I have not found anything equivalent under .NET Anyone know how this might be done I was thinking I might be able to control it using IOCTL_SERIAL_SET_TIMEOUT but have not been able to find a way to access the underlying filehandle. Is there a way The ReadTimeout property uses SetCommTimeouts(). However, it does not apply to the DataReceived event. Only when you make a blocking call to one of the Read*() methods. A Read() method call is usually only p ...Show All

• Visual Studio 2008 (Pre-release) Error: Mapping not found in workspace

  I just start a new model from a simple database and receive this error when I try manipulate some data: The mapping for Entity Container 'ADONextLib.ADONext' was not found in Workspace. The samples from the CTP is working properly. There is a connectionstring in a .config file called "ADONextLib.ADONext" A suggestion to help out here: You can keep related metadata files in a separate directory and load them up at runtime. This allows you to for example, share the same metadata files accross solutions, or can help you to manage different metadata files for different projects in one location. We'll have better ways to manage these files in future CTPs. ...Show All

• Windows Forms Non background image on a label.

  I want to show a little graphic directly to the left of a piece of text in a windows forms applications. The System.Windows.Forms.Label control seems like the obvious place to go for this... I create my Label control and set the .Image property to my image and set the ImageAlign property to MiddleLeft. Unfortunately, the image is underneath the text... not adjacent to it... not exactly what I wanted. (Nor what I expected since other controls, like Panel, call the property BackgroundImage if it is going to be painted under everything else). Then I think... no problem... the same thing happens in System.Windows.Forms.LinkLabel, and I know the solution. I am using a 16px image, so I set the left padding on the Label to be 16.

• .NET Development Soap Extension ChainSream method

  Hello, I use the soap extension to log the request and response soap messages in my web service like documented in the MSDN: http://msdn2.microsoft.com/en-us/library/7w06t139.aspx it works fine with no problem but i want to understand: why we should finally copy the stream from the memory stream to the oldstream. First at the beforedeserialize stage we copied the stream to the memory stream and in the chain stream we returned the memorystream, in the afterserialaization stage i got the serialized message from the memory stream, this means that the .Net framework worked on the memory stream so the serialized message was written on it, so why the response to the client wasn't sent from memory stream, why should i copy it from the ...Show All

• Visual C# still not getting communication between classes

  alright, let me try and explain this: I have a main class that creates new instances of two other classes (class 1, class 2) "class 1" needs to do a lot of work with info from "class 2", but unfortunately can't access it. I could pass it all in as parameters from the main class (which obviously can acess both "class 1" and "class 2" as it created them), but this would be insanely difficult ( due to how much stuff it works with). I thought that i could simply create a public version of class 2 in the code for the main class by saying public classname Class2 ( get { return class2; } set { class2 = value; } ) I then tried to access "class 2" in "class 1"'s code by saying main ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Texture diffusing...

  Hi all - my question is how can I get textures when drawn not to diffuse. This happens when the destination rectangle is bigger than the source rectangle - instead I just wnat to "magnify" the image...stretching the texture out horizontlaly, vertically, or both. With everything I try I either get diffusion (i.e. the image fades as it is stretched, making it semi-transparent), or I get pure black. :S Please tell me what I need to do if possible - thanks very much.
