• Software Development for Windows Vista Trap last browsed URL

  I would like to be able to create something in Vista that "listens" for when a page is opened in IE (I would liek it to listen for any browser..but just IE will be fine).. Does anybody know where I should look for documentation on how to accomplish this Thanks! Looks good, except that it doesn't work when built under Visual Studio 2005. I couldn't get it to recognize a single thing that my Internet Explorer browser did. Is there anything else available that might work ...Show All

• .NET Development Object dieing after some idle time

  Hi, Need some help ragarding remoting . I have an application developed using remoting scneorio. I am using SAO singleton objects. My application is working fine. But when i left the application idle on client sie, (user machine and not server machine) say some half an hour, ,y application returns the error. I found that object is dieing after some idle period. Any guess why this is happening Thanks Vyanki Hi Vyanki, did you check out the document Gandalf referenced It sounds like your singleton is timing out, which is a normal part of .NET Remoting. If you want to control the singleton's lifetime you'll need to register a sponsor. When a lease is set to expire, we ask all the sponsor's if it's OK to coll ...Show All

• .NET Development Copying tables from a dataset to a SQL Table

  I have a dataset with 5 tables and there is a database in my SQL server 2005 with the same set of tables with no rows in them. I am trying to import the rows in my dataset to those in the database.

• SQL Server databases on SAN will not reattach @ SQL server reboot

  Hello. I have a SQL 2000 server running on server 2003. The databases are located on a lefthand networks SAN. At SQL server reboot, the databases will not automatically reattach. You can however manually attach them. No, I haven't tried to automate the restart of SQL Server after the failure. If you're up to modifying registry settings, you could try to modify the service start order using ServiceGroupOrder settings to try and get SQL Server to start dead last.

• Visual C++ "...application configuration is incorrect"

  I created a .exe application using Visual Studio 2005. My app. will run on my development system but when I use my target system I get the error message "...application configuration is incorrect." I studied the web site detailing the /MD option and how MSVCR80.DLL and MSVCRT.LIB become part of my code. I checked the Properties of my project in the project and the /MD option is set. I copied the MSVCRT.LIB and MSVCRT.LIB files to the same directories on my target system as they are on my development system. My app. still will not run. Maybe I need to install Visual Studio to get at the required files instead of copying them So, how do I get my app. to recognize the required .dlls and .libs I have studied other people's post ...Show All

• Visual C++ Converted from C: How to make it accessable from other .Net programs?

  Hi there, I am familar with .Net in generial but really new in C++ .Net. Now I am charged with a task of converting an existing C program into .Net so that it can be accessed by our other .net components. Due to the complexity of the C program, re-witting is not an option for us. That's why C++ comes up as the tool for the task. I created a new C++ .Net project (class library project) and then created a new class file in it. Then I pasted my C code into the class. I also loaded all the header files needed into the project. After a bit of struggle I finally got it compiled! I can also see the DLL file generated. Big achievement, right While, only if I can figure out how to use it. What I want to do now is that I need to make this c ...Show All

• Visual Basic Restarting Windows

  I need my program to be able to restart the computer. However, when I copied the code off of http://support.microsoft.com/default.aspx scid=kb;en-us;176695, but when I run, I get a PInvokeStackInbalance run-time error at the OpenProcessToken line. So if the Microsoft code example doesn't work, does anyone else have an idea on how I can restart Windows Just wanted to second ahmedilyas' suggestion. Using: System.Diagnostics.Process.Start("shutdown.exe", "-s") Is by far the easiest way. You can run Shutdown / from a command line to find all the other parameters available; these allow you to restart, log off, or issue this command against a remote computer (if you have permission). ...Show All

• Visual Studio 2008 (Pre-release) Passing additional parameters to the DataContext

  Hello all, I am working on a ListBox where the selected item should a sub-ListBox (the idea is to simulate a top-level menu, and each menu has a sub-menu). I read Josh Smith's excellent blog-entry on setting the selected item's DataTemplate ( http://www.infusionblogs.com/blogs/jsmith/archive/2006/08/09/699.aspx ) And I worked on that to implement the sub-ListBox.

• SQL Server How to update my program with a database

  I need help to decide how to proceed. I have written a program using vb 2005 express that will create menu items after the user presses a particular button. So if the user picks a mountain dew then inside the reciept window(list box) the user will see 1 MT DEW $1.00 also as the user selects more items the price is calculated and displayed also. This part of the program works fine. After using the program for a while I realized that I will need to update prices and be able to add and subtract items from the menu that customers order from. The way I accompolish this now is to go back into my code and rewrite alot of code. From reading the forums I think that a database would be a good solution because what I have gathered so far is t ...Show All
