• Game Technologies: DirectX, XNA, XACT, etc. Simple Bezier Curves

  After a recent post about doing Bezier curves with XNA, I decided to give it a shot. With the help of some people getting the view set up and http://freespace.virgin.net/hugo.elias/graphics/x_bezier.htm for the equation, I managed to get a simple start to a hopefully powerful Bezier curve system for XNA. The full thing is available at http://cis.gvsu.edu/~gravelyn/BezierCurves.zip. You can see a couple screenshots at http://cis.gvsu.edu/~gravelyn/bezier_screen_1.png and http://cis.gvsu.edu/~gravelyn/bezier_screen_2.png (sorry, I don't know how to make clickable links in these forums). Right now the demo is just two points with one control point each. You can move the start and end as well as the control points. The system approxi ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What is the meaning of loadAllContent?

  I'm not sure I understand the meaning of the parameter loadAllContent to the function Game.LoadGraphicsContent. According to the documentation it is: "true if all graphics resources need to be loaded; false if only manual resources need to be loaded." But what are manual resources Thanks in advance, Per Rasmussen. As I understand it, resources uses memory on the graphics device. A wide variety of events can cause this memory to be lost. When you have a resource that is in Manual mode, you have to reinitialize the memory on the graphics card yourself. When it is in Automatic mode, the framework keeps a copy in system memory and automatically reinitializes the graphics card memory when it ...Show All

• Visual C# Newline problem with running Cmd.exe in a process

  Hi, I'm trying to run a CHDIR command in a cmd.exe process. The command fails to chnage directory because of the newline characters thrown to the end of the string... i.e. chdir d:\\Folder2\r\n\r\n Is there a way to stop the streamwriter from insert \r\n\r\n This doesn't happen in it's VB equivalent.

• .NET Development Write to file that is in use

  Hello I have a problem with file access. I have a service, that reads out an xml file every second.

• Windows Forms How to determine if DataGridView contains uncommitted changes.

  I have a form that uses a DataGridView, BindingSource, DataSet and BindingNavigator to edit a single table in a database. When the user picks the 'X' in the upper right corner to close the dialog box, I need to determine if there are uncommitted changes in the grid, so I know when to ask if they want to save their changes. I'm thinking I can set the current cell to the first cell in each row and call 'isCurrentRowDirty'. Is that the proper way to do this Thanks, Mike Or a really simple way: Use events beginedit and endedit from datagridview. Store the cell edited in beginedit. Check to see if the value changed in end edit. If it has, then set a flag. If the flag is true, then ask them to save. No nee ...Show All

• Visual Studio Team System Test Result

  According to the MSDN documentation on the TS warehouse, the Test Result field (or dimension in the cube) corresponds to the timestamp at the time a test was run. They say that this is "by default". I therefore understand that there is a way to change that. Anybody know how Thanks Thanks for your answer. Just to clarify things, I don't really want to change the test result to something different than the timestamp. I am building a report for where I relying on this field being a timestamp. Since the documentation mentioned that this was "by default" I wanted to investigate if anyone could change it and how (which would mess up my report). ...Show All

• Visual C# C# - How powerful?

  I know C# is sort of like C++, but is it as powerful as C++ We all have to start somewhere and C# is not as powerful as C++ but it is easier to learn. Previously I would of said just learn C (module based and unmanaged) or Java (Object Orientated and Managed) as they have free compilers, but with the introduction of the free express edition it opens a whole new kettle of fish. Have a go at programing some example programs in C#, it will teach you some methods and standards. These forums are excellent for getting help however difficult the problem. ...Show All

• Software Development for Windows Vista pause on Fields

  can i pause my graph both on any field that i want in a interlaced video Exactly. For example, if you grab a DV frame once it is decompressed (i.e. one media sample at the level of a transform filter in RGB), you will see that the two fields are combined in the same frame : even lines for one field, odd lines for the second field. On a PC, the renderer normally does deinterlacing before presenting. If you want to be able to pause on each field, you need to split one frame into two frames (one for each field), which means that you cannot use a "simple transform filter", but a special filter which doubles the number of samples. You have two points to care about : 1) for each field, you need to ...Show All
