SQL Server Detaching and moving databases
Not sure if this is the exact forum I need but here goes. Having a bit of an issue 'moving' a database. I've only just installed SQL Server 2005 on a Development/Test box so I can learn and mess around with it without doing any serious damage to anything important. One of the first things I've done is install the AdventureWorks database and, having installed it, decided I would move the files to their optimum locations. However having detached the database I can't seem to move or copy the .mdf or .ldf files - something still seems to have its tentacles around them - 'Access denied' error. Even rebooting the server doesn't work. So I've had to delete then re-attach the database. The question then is does Detach serve any useful purpose Or a ...Show All

Visual Studio 2008 (Pre-release) Can i debug the service developed using WCF.
hi, I want to debug the service that has been developed using WCF. When i inovke a method exposed thru a service i need to debug from the client to the service. Both me client and service are on the same machine. Is it possible to debug Thanks in advance. Regards, Rajesh. If you use VS2008-Orcas CTP this problem will vanish. if you use VS 2005 you will have to manually attached the debugger to the process. of course you must set the break point firstly. the steps to attached debugger to the target process is: 1. Insert the break point both the client end and WCF end. it is very important that you must set the break point in the WCF end 2. Click the menu item, Debug/Attached Process ...Show All
Windows Live Developer Forums Display Search Results in a <div>?
Hi, I tryed to display the search results in a div(like how I added on Driving Directions to my site and it would display the directions where I put the div), and I can't seem to do it. I am trying to make a major mashup like Atlas but I could never display my search results in the area.

Audio and Video Development Pause\Play on 1 button on my popup menu
I have a popup that I want to have 1 button that is "pause" when he movie is playing but after pressed it turns into a play button...I know how to animate its state so that it shows "play\pause" graphics but in my script I need to know a good if\then command for this button. Case "menu_1" player.playlist.pause(); thats what it is right now and it pauses the video and switches to the "play" graphic for the button...just need a good if\then script for Case "menu_1" Thanx in advance! Also I would recommend NOT changing the graphic when the button is pressed, since that won't work if the user presses the pause key manually. Rather, I would trigger the graphic change based on the playsta ...Show All
Visual Basic Is there a DataGridView RowDirty Property?
I am running some code in the DataGridView.RowValidating event. What I need to do is figure out is the user actually "changed" anything in the current row. Unfortunatly I can't seem to find a IsDirty property for the row, or even for the cells (worst case senario I could have looped through each cell checking the Dirty flag). When I try to check the RowState of the DataBoundItem, I get back "Unchanged". Now in reality, that is not true. But when tracking the code, it appeard that when I change a cell, the change immediately get's pushed to the underlying table object, before the RowValidating event fires. That seems a bit backwards to me. I thought changes made to the data on the grid should only get pushed to the under ...Show All

Visual Basic Calculate the exact differences between 2 given dates
TimeSpan supports only up to Days. How best to get the exact differences between 2 dates in years, months, and days I searched online and most methods only provide the average by assuming number of months or numbers of years and such. DateDiff won't work, because according to the documentation: When comparing December 31 to January 1 of the immediately succeeding year, DateDiff for Year ("yyyy") returns 1 even though only a day has elapsed. Try this function. It could be faster, but it seems to work for the tests I have made for it (it assumes y comes after x): Public Sub DateSpace(ByVal x As Date, ByVal y As Date, ByRef years As Integer, ByRef months As Integer, ByRef days As ...Show All
