• Game Technologies: DirectX, XNA, XACT, etc. Alpha blending not working with C# and Managed Direct X 9

  Hello, I'm trying to render a 2 triangle strip with alpha transparency. Here is the bitmap loading code, I have tried both methods with no luck: particleTextures[0] = new Texture(device, new Bitmap("alphatest.png"), 0, Pool.Managed); and particleTextures[0] = TextureLoader.FromFile(device, "alphatest.png", 0, 0, 1, 0, Format.A8R8G8B8, Pool.Managed, Filter.None, Filter.None, Color.FromArgb(255, 0, 0, 0).ToArgb()); This is the drawing code: CustomVertex.PositionTextured[] verts = new CustomVertex.PositionTextured[4]; verts[0] = new CustomVertex.PositionTextured(-10.0f, 10.0f, 0, 0.0f, 0.0f); verts[1] = new CustomVertex.PositionTextured(-10.0f, -10.0f, 0, 0, 1.0f); verts[2] = new CustomVertex.PositionTextured(10.0f, 10.0 ...Show All

• Visual Studio Express Editions Accessing elements from a different window form

  Hey everyone, Just downlaoded C# EE (Express Edition) the other day and ive gone through the 10 hours of Absolute Beginners videos, so i have a decent understanding of C# now and the way Visual CSharp Express Edition 2005 works. My question is this, Say i have a new Windows Form popup as a dialogue box with a single text area known as textBox1, and when someone clicks on the "Add" button it is to add the contents of the textbox onto a RichTextArea known as mainWin in the "main" class. So what im asking is, in the class button click 'contructor' i think its called (when you double click on the button in the designer view) How would i go about accessing main.mainWin (and its set to public) (ps. id LOVE to post source co ...Show All

• Visual C# Use function from DLL file

  Hi, I'm a beginning C# programmer and I'm writing an earlier written program(c++) in C#.

• Internet Explorer Development IE7 the culprit? outlook express hotmail problem

  I use OE6 to archive my hotmail locally via dial-up until I installed IE7 and then I'm requested to logon when synchronizing my hotmail folders. I have not been able to logon yet and synch my mail. I also have McAfee security running and have disabled it to see if the connection is being firewalled to no avail. I just need to know for sure if hotmail is no longer available to OE users or there is an easy fix to restore what was a very handy facility. Help! Afew minutes after I posted this I found KB907942, an obscure update that Most Magnificent Microsoft has for just this problem. I will repost if it doesn't work. Duh, my bad. KB 904972, it was late after a long day when I posted. My apologies, Hope th ...Show All

• Visual Studio Express Editions How to create a shared folder on a file server and assign share level permissions.

  Hi, I am very new to VB but I have built an application that needs to create a shared folder on a file server and then set NTFS permissions as well as share level permissions. I have search for hours on how to do this and I have come up empty. I got it to work by running a shell command but I am a little disapointed by the dos pop-up windows that come up. Not to mention I am relying on XCALC.BAT and RMTSHARE.EXE for it to work. If there is no easy way to get VB to do this than can I use some shell command that does not pop-up when it runs that part of the app Any Help would be much apprecitated. In .NET you can set the file or folder attributes and add the accounts you want accessed to that folder. As for making it a physica ...Show All

• Windows Forms TreeView Owner Draw problem

  I'm trying to draw my own tree views but I get a strange result. My code is essentially private void TVDrawNode( Object sender, DrawTreeNodeEventArgs e) { e.Graphics.DrawImage(e.Node.TreeView.ImageList.Images[e.Node.ImageIndex], e.Bounds.Left + 15 * e.Node.Level + 5, e.Bounds.Top); e.Graphics.DrawString(e.Node.Text, e.Node.TreeView.Font, Brushes .Black, e.Bounds.Left + 15*e.Node.Level + 30, e.Bounds.Top); } and later DirTView.DrawMode = TreeViewDrawMode .OwnerDrawAll; DirTView.DrawNode += new DrawTreeNodeEventHandler (( DrawTreeNodeEventHandler )TVDrawNode); When I run this for the first time I get http://server6.theimagehosting.com/image.php img=TreeView1.gif (except ...Show All

• Visual Studio 2008 (Pre-release) sending 30 MB from a WCF server to many clients

  I need to create a solution for this scenario: A lot of clients all over the world (winforms) should play media files that a server sends them. The server has a playlist of media files for each of those client. Whenever a playlist is changed on the server the client should 'know' about it and download the media files. the size of the files could be around 30 MB. Should I use WCF to send the files to the client or should I use FTP instead What is the diference between WCF and FTP in terms of speed , security and scalability i think u should use windows media service instead of use wcf. The stream media service is better than wcf is at this case. ...Show All

• Visual C# Finding a process name from an address.

  If i have a string that contains an address to a program, or other file, how can i remove the address up until the point of the file I've tried using the substring method, but that only works up to a point. I can remove the drive letter and semicolon, but then it doesn't remove the backwards slash.

• Game Technologies: DirectX, XNA, XACT, etc. Multiple Cores, etc... on the 360

  Hello everyone, Like practically everyone here, I'm truly excited about the idea of being able to run my own games on the 360! I've long been interested in the concept of running my own code on a console and it's always annoyed me that systems needed to be locked down so heavily because of the pirates who spoil the fun for all of us. So I just want to say thanks to Microsoft for giving us hobbyist/one-guy game developers the chance to develop for the console like this! It's like my prayers have been answered! Now for a couple of questions: 1) I'm just wondering how the multiple cores in the 360 will work Will the managed code automatically utilize all three (well, in effect, six) cores or w ...Show All
