• SharePoint Products and Technologies workflow triggered during upload but after the user enters values in the properties dialog

  1) When " Start this workflow when a new item is created " option is selected the workflow gets triggered as soon as the file is uploaded and even before the 'edit properties' dialog is displayed . I want the workflow to be triggered after the properties are entered by the user on upload. 2) Selecting "Start this workflow when an item is changed." option also does not trigger the workflow during upload. This triggers only when the user explicitly selects 'Edit Properties' dialog. So my question is, how to get the workflow triggered during upload but after the user enters values in the properties dialog. That didn't make any difference. I don't have a problem inputting the ...Show All

• Windows Forms Vista Controls coming soon?

  When, if ever, will VS be updated to the new Vista forms controls I have found a few add-ins on the net that will give my form that Office 2007 feel, but the last thing I want to do is purchase something that will be outdated with a service pack.

• Visual Basic Unloading a picture from a picturebox in VB.net

  I have done some code to load a picture in an array of bytes. The data is saved in a file in the Hard drive. There is also another piece of code to display the image. My issue is that I need to unload the picture before the user press the button to refresh and therefore reload the image. Generally I would have an error when I try to download the file and save it. I will have an error that the file is being used by another process. Noticed that picturebox1.load = nothing will unload the picture from the picturebox but it will not close the file completely before going the next instructions. Checking "If picturebox1.load is nothing = true will be true and therefore there will no way to identify if the file has been closed or not. I do ...Show All

• Visual Studio 2008 (Pre-release) TreeViewItem: hide item when it is the last node in the tree level

  I have a TreeView and for the TreeViewItem I have created a style with a ControlTemplate in it. One of the elements is a line to connect all the tree nodes (visually, that is). But for the last node in the tree level it should hide this line, because there is no other node to connect to. The way I was thinking to do this, is to set the Visibility of the line element by using a Binding string/statement/whatever it is called: Visibility="{Binding Path=..., RelativeSource={...}}" RelativeSource should then point to a property of some sorts which tells me if the current TreeViewItem is the last node in that level. Is there such a property available Or has anyone done something like this before and knows how to do it ...Show All

• SQL Server Import Column Transformation

  I have a SQL Server table that has a "Text" type column. RTF files are stored in this column. On a monthly basis, new or updated RTF files are dropped into a shared folder. I need to upload these into the SQL Server table. Reviewing some of the entries in this forum, I know I probably should be using the Import Column Transformation, but for the last week I can't get it to work successfully. Another column in the table contains the unique file name(varchar). At runtime the user inputs the fully qualified path to the RTF files which I store in an SSIS variable. Within the package I use a Derived Column Transformation to concatenate these two elements and then pass them as input to the Import Column. I'm expecting the RTF file ...Show All

• Visual C# Playing cd's with mci question

  I am trying to write some code to play a CD from a drive and the user can indicate what track to play. I should be using this format, as far as I know: mciSendString("open cdaudio", null, 0, IntPtr.Zero); mciSendString("play cdaudio from 3:00:00:00 to 4:00:00:00", null, 0, IntPtr.Zero); So this would play from the 3rd track to the 4th. This does not work, it seems to start in the middle of the first track or the track that I want to paly (3). Any advice Thanks you should really stay away from using mciSendString and move on to newer better methods. Why don't you embed WMP into your application and use that to play your CD http://msdn.microsoft.com/w ...Show All

• SQL Server Question On How to get the Table object to filling blank space on page???

• SQL Server WHAT NEXT AFTER INSTALLING SQL SERVER EXPRESS?

  I have installed SQL Server Express with Advanced Services SP1 option. I am not really sure if I should have done this but I could not resist the temptation to have as many options as I could get. I even installed some samples/sample databases. However, I cannot understand how to start using the SQL Express package which (unlike the Visual Basic 2005 Express or the Web Developer Express I also downloaded) does not show me a start up page. I get SQL Server Configuration Manager, SQL Server Error and Usage Reporting and SQL Server Surface Area Configuration, all from Configuration Tools. I have no idea how to proceed.
