• Internet Explorer Development My php download script does not work anymore

  Hello, On my web site, I use a classical php script to allow file download after registration. Since IE7 has been installed, I cannot (and my clients neither) use IE to download files (FireFox or Opera still work fine, IE6 worked fine too). Message is: "Internet Explorer cannot download .... IE was not able to open this internet site. ...either unavailable or cannot be found." Here is a simple PHP script to illustrate my problem: < php header("Cache-Control: no-cache"); header("Content-Type: image/jpeg"); // or "application/download" header("Content-Disposition: attachment; filename=myImage.jpg"); header("Content-Description: Download image"); // or program $f ...Show All

• .NET Development TcpListener

  Hi. I'm trying to make a simple application which receives data from a local host and displays it. Everything works fine upto the point where it's supposed to connect to theclient. However, when I type in whatever I want to send, I keep waiting for it to come back...an eternity thingy. Heres the code: using System; using System.Collections.Generic; using System.Text; using System.IO; using System.Net; using System.Net.Sockets; namespace MyTcpListener { class Listener { public static void Main() { TcpListener server = null ; try { Int32 port = 9000; IPAddress localAddr = IPAddress .Parse( "127.0.0.1" ); server = new TcpListener (localAddr, ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What are all the scrip codes for XNA?

  I know almost all game develpement programs use scrip codes and I would reall like it is someone would tell me some I would like to know them all Also whats the code to make cheat codes The problem with your question is that XNA has no specific script codes. Each developer that makes a game using the XNA Framework will decide for themselves if they want to create their own scripting system for their game and they will either use an existing system (of which there are many) or implement their own. Also, there is no specific code to make cheat codes. Technically, I guess you would say that C# is the code to make cheat codes in XNA. If a developer wants to add cheat codes to his game (usually done for test ...Show All

• Visual Studio Team System MSBuild FlavorToBuild being ignored

  I setup two build types for a team project, one is a testing debug build and the other is a production release build. It seems that no matter what I put in the FlavorToBuild the solution keeps getting build with the Debug configuration. One of the projects in the solution is a web deployment project that swaps sections of the web.config depending on the build configuration so the final output keeps setting this incorrectly. I currently have this in the TFSBuild.proj: < ItemGroup > < ConfigurationToBuild Include = " Release|Mixed Platforms " > < FlavorToBuild > Release </ FlavorToBuild > < PlatformToBuild > Mixed Platforms </ PlatformToBuild > </ ConfigurationToBuild > ...Show All

• SharePoint Products and Technologies InvokeWorkflowActivity doesn't call workflow

  I'm trying to get one workflow to call another one. I tried using the invokeWorkflowActivity, I set the TargetWorkflow to the workflow that I want to get called. It's in another project so I added the project as a reference. What else do I have to set up in order for this to work properly. I get no errors, the first workflow starts and then completes as expected because the call to start the workflow is asyncronous. The problem is that my second workflow doesn't seem like it's getting called. I only associated the 1st workflow, do I need to associate the 2nd workflow too Thanks, -Somsong ...Show All

• Visual C# Utils Class inquiry

  Utils Class appears to be undocumented. MSDN says that it is intended for use by the OS system only (VB compiler) and not supposed to be called directly from C# code. I came across exactly the opposite and when I tried to invoke it in Intellisense it appeared the class has a lot of useful method I badly need. It appears some of them are self-explainatory but others are a bit more obscure. Anyhow, I wound not mind to read more on that class. Where can I find a source Thanks. Download Reflector (you should be able to google it rather easily) and see what those utility functions are doing under the hood. ...Show All

• Software Development for Windows Vista Problems with WMI classes Win32_VideoController, Win32_VideoSettings, and CIM_VideoControllerResolution under Vista.

  Under Vista, attempts to access Win32_VideoSettings and CIM_VideoControllerResolution objects via WMI return no records. The online documentation claims that Vista is a supported platform. The Win32_VideoController object returns records but all the CurrentBitsPerPixel, CurrentHorizontalResolution, CurrentNumberOfColors, CurrentRefreshRate, CurrentVerticalResolution, etc., are all empty. Further, the Availability value for every controller is set to 8, (OffLine). I'm having no problems obtaining WMI information from Vista, exactly like that under XP, except for the three that I mentioned. Is this a bug under Vista, or has the information moved somewhere else The information has not moved. These are ...Show All
