• Game Technologies: DirectX, XNA, XACT, etc. Bug with SpriteBatch.Draw scale?

  I'm working on a particle system. While experimenting, I created some scale and rotation tests to make sure the particle system is working as expected. For these tests, I am using both positive and negative values for both the scale and rotation factors. With rotation, a positive value rotates the sprite clockwise and a negative value rotates the sprite counterclockwise. That's fine. I then tried scaling. When I increased the scale factor, the sprite enlarged as expected. However, when I decreased the scale factor, the sprite shrank but ONLY WHILE THE SCALE FACTOR WAS POSITIVE. As soon as the scale factor became negative, the sprite began to enlarge again! In mathematical terms, it appears the sprite is using the Absolute Value of th ...Show All

• Visual Studio Tools for Office Bind the existing listobject without hard coding the Sheet name

  My VSTO application contains more than 100 sheets. In all the sheets there is one list object and a chart bind to it. I can access the list object SetDataBinding as follows. Globals .Sheet2.list1.SetDataBinding(); Is there any way to bind the existing listobject without hard coding the Sheet name. For example: Excel. Worksheet activeSheet = (Excel. Worksheet ) Globals .ThisWorkbook.Sheets[1]; activeSheet.ListObjects[0]. ( here SetDataBinding() is not available! ) It is possible to add listobject dynamically using Control.AddListObject() and that method is returning ListObject instance, for that SetDataBinding() is available. But I need to bind the existing list object. Is ther ...Show All

• .NET Development Notify user of session timeout?

  Hi, I need to notify the user when the session times out and I supose I'm looking to solve two things. 1. I would like to warn the user a minute or so before a timeout occurs and allow the user to extend the session. 2. If the session times out, then I want to redirect the user to a "you're logged out page". How is this done Thanks! This isn't related to web services unless you built your own web services authentication. By default the session timeout for the ASP.Net forms authentication is 20 minutes. You could have a javascript counter on each page that warns them when the timeout is about to occur: window.setTimeout(myalertfunction, 19 * 60 * 1000) //warn after 19 minutes funct ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. No typedef and no Include. . .

  Are these VBA programmers writing the .Net framework and languages Many of you probably already know this, as I'm arriving late to the party. I wanted to use the typedef equivalent but apparently not in C#. Then of course I thought I'd try the #include -- maybe so, if I wanted comments (I gather). The end result: Common.cs using System; namespace <yoursHere> { using ID = System.Int32; public class objID { private ID itsID; public objID( ID theID ) { itsID = theID; } public ID ID { get { return itsID; } set { itsID = value; } } } } Did I miss something r2d2-proton wrote: Did I miss something Depends on what you were trying ...Show All
