• Visual Studio Express Editions Combobox and Datagridview

  HI, I apologize if this has been covered. I'm sure there is a quick solution for this. I'm want to be able to take a selection from 2 comboboxes and display this data in a DataGridView. The Comboboxes are filled with data from a Database. Also I only want the GridView window to display data from the selection not everything in the table, so it would remain blank until a selection is made. One last thing, how do I stop duplicate data from being displayed in the comboboxes. Should I setup separate tables and make the tables relational Thanks in advance. Peter I think were making some head way, but I must be missing something. 1. I added a button so that the user after sel ...Show All

• Visual Studio Microsoft Document Explorer Index

  I installed Visual Studio Team 2005 on my WinXP with no problems. For some reason (perhaps the order of my installation) my help index in the Microsoft Document Explorer only has SQL server help in it. I have gone to the control panel and tried to reinstall and add new products but everything is already installed and there is no section for install VS help that I could see. The problem with this is all errors for any language (like C#) in VS usually have a link associated like "Click here for more help on this error" and when you click on it the document explorer says No help was found for this error. When I start document explorer the "index" window "Filtered By:" drop down only has SQL Server 2005 stuff list ...Show All

• SQL Server ability to use variables in package configurations and set their values at runtime

  Hi, My scenario: I am using a FTP Connection Manager and the configuration setting for it is being set in the package configuration xml file. So the xml file contains the Ftpserver, FTp server username and password. The package is picking up the values from the xml file and is executing successfully. I have to do this because I was not able to provide an expression to the Connection Manager Server Password property. Now, I want to pick up the ftp details from a database table and set it in the xml file during runtime. Is this possible OR something like using the <Configuration ConfiguredType="Property" Path="\Package.Connections[FTP Connection Manager].Properties[ServerPassword]" ValueType=" Variable "><ConfiguredValue ...Show All

• Visual Studio Tools for Office CommandBar Button Images when disabled...

  Hello All, I have an addin (Outlook specifically) that creates a command bar with buttons that have images. I am using VSTO 2005 in C# for this addin. The problem I have is that when I create these buttons and images, when the buttons are disabled, the mask looks pretty bad. I couldn't find a way when the buttons are disabled to show a better greyed out image than using the mask. How can I get my buttons to have a good disabled image (similar to the 'Reply', 'Reply All', 'Forward' buttons) when they are disabled Currently I set the buttons like the following: m_btnTBRefresh.Picture = ImageToPictureConverter .Convert( TeamlookRes .refresh_16); m_btnTBRefresh.Mask = ImageToPictureConverter .Convert( TeamlookRes .refresh_16ma ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Removal of ID3D10Device::CheckVertexCache()

  Hi, I've had a bit of a break from Vista/D3D10 and just recently got a Beta-2/June SDK setup running and am getting back into D3D10 programming again. I noticed that the ID3D10Device::CheckVertexCache() method got removed between April'06 and June'06 SDK's - why ! The release notes nor the documentation seems to suggest an alternative (that is, its not just a syntactic change). Hopefully I'm not being blind and missing an equivalent way of getting this info I found the cache size information to be extremely useful in D3D9 (even if ATi hardware never exposed it) - I wrote about one particular use in my developer journal ( here and here ). I know that D3DX9 has various optimizing functions (I presume it has cache information) ...Show All

• Smart Device Development Socket Error in HttpWebRequest using .NET CF

  Hi all, My PDA application is currently encountering an "An operation was attempted on something that is not a socket" error when uploading large files (22 mb) to a webserver using HttpWebRequest with its property SendChunked = true and AllowWriteStreamBuffering = False. I tested it with SendChunked = false and AllowWriteStreamBuffering = true and get an OutOfMemory exception instead. Do you guys know what are the possible causes of this Might it be that the Socket error and the out of memory exception have the same cause A little background: The program memory allocated to the PDA is about 50mb, more than twice of the uploaded file, thus i was wondering what might cause of this "OutOfMemory" exc ...Show All
