• Game Technologies: DirectX, XNA, XACT, etc. my first game - how?

  I'm VERY VERY new to directX. So I apologise for asking this question I have used directX once, managed directX, within my C# app but this was for audio related stuff and it was very cool. Firstly, hats off to the top jocks at MS DirectX team for providing us with all these technologies - thanks. Now, I am wanting to know how can I go about writing a VERY simple basic game - this game would be like a shoot 'em up style. Example: 1 spaceship shooting other incoming objects. That's all. I am wondering what is the best place/area to look at to get me started What do I do How do I create graphics (basic) how do I make the spaceship move from left to right using the arrow keys These types of questions I would like to know and w ...Show All

• Visual Basic null reference in passing array between procedures

  Hi, I'm trying to write a program that grabs data from a text file and populates the array of a structure, but I've been getting a "system.nullreference exception: object reference not set to an instance of an object. at A.Readfile(string file, schedule{} & flight) at A.Main(String{} arg) Sample code:  Public Structure Schedule         'members of the structure         Dim Airline As String Public Sub Main(ByVal arg() As String) Dim flights() As Schedule 'a structure previously defined Dim response As String ReadFile(arg(0), flights ) 'i think flights is causing the problem, but not sure how etc, Sub Readfile(B ...Show All

• Visual FoxPro How to remove redundant phrase in field?

  Hi all........ I have a table field that contains things such as..... V DISCONTINUED W/O REPLACEMENT; V DISCONTINUED W/O REPLACEMENT -I&S MASTER; 7 SUB 2610-139-3704; I&S MASTER; 7 SUB FOR 2610-139-3704 What I need to do is remove the duplicate phrases, leaving only one instance of each phrase in the field. The amount of phrases in the field varies...could be 2 as shown above or there could be 6. I suspect that the 'common denominator' is the semi-colon, but everything I've tried has failed. Any help is greatly appreciated! First you should determine what a sentence is, for example: - From a delimiter (start, ";", end) to another. - A certain quantity of char ...Show All

• SQL Server Restart of SQL Server Agent needed - every day

  Hi, I'm having a very strange problem here. I've got a few SSIS-packages here which runs as Server Agent Jobs. They are scheduled to run every hour. This is what happens: on the first run, all packackes are running and completing all steps successfully. After that, at the second start of the jobs, activity monitor shows "executing step 1", but nothin happens anymore. To get the jobs running again, I need to restart SQL-Server Agent Service. I really have no clue whats wrong with my agent. Any suggestions/hints Regards, Jan Hi, I was wondering if you've found a solution to this problem. I haven't released my project yet but I am concern about this message in my logs. My logs ...Show All

• Internet Explorer Development Wrap selection or IHTMLTxtRange in Font or Span tags of a given class

  I am trying to wrap the users selection (or a IHTMLTxtRange) with font or span tags that have a given class. The best that I can do now is: pRangeToRender.execCommand("BackColor", false, SOMECOLOR) I then use IHTMLElementCollection allEls = doc.getElementsByTagName("FONT"); and check each tag if it's SOMECOLOR. If it is, I clear the color and set the font tag's class. This is quite slow on large selection. Is there some better way to do it This is kind of a shot in the dark as I have never tried this, but perhaps you could retrieve the block of text using pRangeToRender.htmlText. You could then wrap that with a SPAN tag, and then try to re-insert it by setting the pRangeToRender.text p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. No text input in WinForm controls

  I am putting some WinForm controls on the Game's window, like this: protected override void Initialize() { // TODO: Add your initialization logic here TextBox t = new TextBox (); Form f = ( Form ) Form .FromHandle( this .Window.Handle); f.Controls.Add(t); base .Initialize(); } This works fine for Buttons etc., but entered text does not show up in a TextBox. Not using Keyboard.GetState() does not help. I suppose that the game window consumes all keystrokes and does not pass them to the controls. Any help Thanks, Leaf.

• SQL Server You are not authorized to view this page

  I cannot access the SRSserver/reports page and get a 401 error, no matter what credentials I supply when prompted. This is a 2005 SRS install, with a distributed model - the database is located on a separate server. The account I am using is an admin on both servers (and in SQL). I've tried enabling anonymous logon on the /reports virtual directory and that didn't help I've used Filemon to see if there were file system permission problems...it showed no failures. I created a test text file in the reportmanager directory and am able to view that, so it's something that the home.aspx file is trying to do. I'm able to connect to the remote SQL server with Management Studio and everything in the SRS Config app is green. Than ...Show All
