• Game Technologies: DirectX, XNA, XACT, etc. Where to upload demos?

  Ok so I have an XNA demo game I want to upload but I don't want my web site to get slammed. Is there a good site to upload the demo to or something like a blog/dowload site that I can start I would like something XNA or MSFT based if possible. Thanks. I wouldn't be worried about being slammed in the XNA community, most of us are beginners here and even the experience joe blogs are very helpfull and almost never negative. Good to you puting your demo game out, I also would suggest if you intend to develop the game further, put it Codeplex , great place and you dont have to release the source if you dont want to, until your ready. One you've put it somewhere put a sticky in this forum, I think Dav ...Show All

• Visual Basic Setting control focus on an MDI child form

  Hi, I have an MDI application with child forms that contain a DataGridView control. Only certain columns in the grid are modifiable and in the CellEnter event I set the EditMode to EditOnEnter so that the user doesn't have to double-click the cell in order to edit. In my main MDI parent form I am trying to write the code that occurs when the Save and Save All buttons on the toolbar are clicked. I currently have this code in mySave routine: Try activeChild = Me.ActiveMdiChild theGrid = CType(activeChild.ActiveControl, DataGridView) Call SaveWorksheet(theGrid) Catch ex As System.InvalidCastException MessageBox.Show("The datagrid was not the active control", "Cast Error", MessageBoxButtons.OK ...Show All

• Windows Forms Drag and Drop Derived Objects

  Hi there. I have a .Net 2.0 Windows Forms C# app and I am trying to implement drag and drop between 2 datagridview controls. In the MouseDown on Control#1 I have set the data to be as follows: DragDropEffects dde = DoDragDrop(( ClosingStmt_LineItems )selectedLineItem, DragDropEffects .Move); Note the selectedLineItem is of the derived type ClosingStmt_LineItems. How can I get the data back out in Control#2's DoDragDrop method It looks like the GetData method only handles basic types. I have tried various attempts at something like this with no luck: ClosingStmt_LineItems tempLineItem; tempLineItem = ( ClosingStmt_LineItems )e.Data.GetData( "" ); I always get tempLineItem = null.

• Game Technologies: DirectX, XNA, XACT, etc. Fullscreen problems....

  EDIT: I am using Beta 2. I use this as the constructor method... public Game1() { graphics = new GraphicsDeviceManager(this); graphics.PreferredBackBufferWidth = 640; graphics.PreferredBackBufferHeight = 480; graphics.PreferMultiSampling = true; graphics.ToggleFullScreen(); content = new ContentManager(Services); } Works great. But when I change the resolution to 800x600, all I get is a black screen. The loop is still running because I can still quit the program. I have also tried 1024x768, that works too. Thought maybe it was an aspect ratio problem, but they are all the same, 1.3333... I have tried turning the multisampling off to no avail. Didnt think that would be it anyways, I play World of Warcraft at 800x60 ...Show All

• Visual C++ place for code

  maybe this is a stupid question, but I have started microsoft visual C++ today (c++ itself also for the first time) and i dont know where to put the code. i'm making the program hello world, but it doesnt work it asks if i want to 'build' the programm and i dont know what it means. i named the program hello and i put the code in the place where it says: hello.cpp is this the right place if so, what am i doing wrong this is the code: // hello.cpp : Defines the entry point for the console application. // #include "stdafx.h" int _tmain( int argc, _TCHAR* argv[]) { return 0; } #include <iostream.h> int main() { cout << "Hello World!\n" ; return 0; } ...Show All

• Visual Studio 2008 (Pre-release) GridViewColumnHeader: Prevent column reorder for one column

  I have a ListView control whose View is a GridView object. I've set the AllowsColumnReorder property to "True" on the GridView object, thus allowing the user to reorder the columns within the Grid. My problem is I would like to prevent the user from reordering just the first column. The other column headers should allow reordering. All attempts to prevent column reordering of the first column thus far have been unsuccessful. Thanks for any suggestions. ...Show All

• SQL Server Earlier question on ODBC compatibility

  Hi Chris: I am sure as you are aware only data adpaters in SQL 2005 out of the box are .NET Frameworks, in your answer to Stoobs, you state the ADO.Net framework does not have all the APIs. We're experiencing the same problem with the product and ODBC. Unfortunately we have a legacy MUMPs DB (that KBSQLODBC layer sits on top of, its a flavor of SQL from Knowledge Based systems) that our vendor is not going to update. Given that, how can we address the ODBC driver problem with SQL 2005 Is there going to be an update to ADO.NET Thanks, dfreshman The trick to this was knowing not to use the Data Source View. I had to create the Data Sources, add them to the connection manager make sure their ...Show All

• Visual Studio Help With Installing Visual Studio 2005 Professional

  Could someone please tell me step by step what I need to do in order to install Visual Studio 2005 Professional. I have downloaded the En_vs_2005_Pro_90_Trial.img file but from here I am completely lost. I am looking for some way to install this program into my computer without having to purchase the ISOBuster software or possibly any other software for that matter. I am a total newbie to any sort of file like this (.img) and just about everything I have read concerning it confuses me. I do have a CD burner but I don't even know how to use it, so when I read about burning the VS2005 file to a CD I am lost here also. If someone could explain in laymen's terms how I can install this file into my machine I would greatly appreciate it ...Show All

• Software Development for Windows Vista security of PPI

  How secure is the Private Personal Identifier (PPI) of a self-issued InfoCard Anyone who knows the PPI can use it to clone a new card and steal my identity. Let's say I make a self-issued card and lock it with a PIN so nobody else can use it. Can the PPI of a locked InfoCard be learned by examining the contents of the CardSpace database file (CradSpace.db) If not, then can the PPI be derived from the contents of an exported backup (.crds) file Thanks Caleb, exactly the information I was looking for. However, I'd say that's not "just" a second line of defense -- just about anyone with physical access to the PC can generate (and of course decrypt, since they are choosing the password) an export fil ...Show All
