• SQL Server expressions

  Maybe I just have my eyes closed as I search for how to do this, but can you refer to a textbox value in an expression something like; Value of textbox1 = textbox2.value Use this syntax: =ReportItems!TextboxName.Value However, keep in mind that for instance you cannot refer to a textbox that is contained within a data region (list, table, etc.) from somewhere outside that data region. Additional restrictions apply. -- Robert ...Show All

• Community Chat Forums Live.com Search Constructor

  A couple of months back, I wrote a very simple WinForms applet that allows you to use Live.com search to search through the forums, because I really don't like the search application on the forums. It also copies RSS feeds to your clipboard, so you can subscribe to searches of things that are interesting to you in the forums and stay informed. If you want to try it out, you can download it from GotDotNet CodeGallery here: http://www.gotdotnet.com/codegallery/codegallery.aspx id=eb5f1dc5-6868-4fde-9c78-909832315ccc What do you think ...Show All

• Visual Studio 2008 (Pre-release) XAML perform transform THEN set a property?

  I want a control of mine to shrink (i.e. ScaleTransform), and THEN I want to set the Visibility to Hidden after the transform is over. Can this be done in XAML How do I set other normal control properties at a specific point in time like ClipToBounds, Dock location, etc. Thanks! P.S. The code segment here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=952995&SiteID=1 did not work. It did not like the <Visibility>Hidden</Visibility> part. VS 2005 told me it was not legal. In any case, I got it working another way, thanks. ...Show All

• Visual C++ Limiters /Delimiters, Managed C++

  The String::Split function is very usefull, but I've got an ever increasing number of delimiters to use with it, including characters from UTF-8, like those pesky curly quotation marks that Word puts on everything and look like foriegn lettters when opened in anything else. Is there a method that will specify what you don't want delimited instead i.e, if it isn't an ASCII upper or lower case letter or number then it is a delimiter. No, you will have to write your own split function or maybe try to use regular expressions. PS: Such questions are better asked in a forum like ".NET Base Class Library": http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=39&SiteID=1 Th ...Show All

• Visual Studio Express Editions Serial port communication and exit application

  I would like to start off by saying I have no idea what I am doing. I am trying to piece together a very simple program that will send 4 bytes of data to the serial port (com2 to be exact). I have downloaded Visual Basic 2005 Express Edition and using this forum have come up with the following which works to a degree. It gets the info sent and the device I am controlling does what its suppossed to do. Only problem I have now is the application will not end unless I click to close the window. I have seen lots of people get referred to a "console" program but when I try I get no tool for serial port and get lots of declarations errors. All I need is this code to get sent and the app to close and it has to do it without user interve ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotation help

  I think I'm being dense today, but I can't figure this out for the life of me. I have a model that I want to rotate across the X and Y axis. My issue is that when I rotate across the Y axis, I always want the rotation to occur as if the axis was vertical in terms of world space. If I multiply by my X rotation first, obviously the Y axis moves with it, so rotating about the Y axis will rotate it about its transformed axis. If I multiply by my Y rotation first, the X axis moves with it, so my X rotation is now turned along with it. I basically want to rotate downward and then left/right independently from what the actual transformed axes become...or, rotate left/right and then downward independently.  When I rotate about the X, it shoul ...Show All

• Visual Studio 2008 (Pre-release) remoting IQueryable

  Problem: to execute linq query on Iqueryable object that is non local (remote object) Solution: generic IQueryable local proxy that will call some remote proxy, and this remote proxy will locally IQuery remote object why not just remote this Iqueryable remote object – because Expression is not serializable in fact Expression can have local code calls so in some situations it may be hard to serialize it. BUT some subset of all-possible-Expressions-set IS serializable. Actually (today): “could be if done manually” questions: - will there be any mechanism like above solution in final orcas bits - anyone already done such generic IQuerya ...Show All

• Visual Studio 2008 (Pre-release) Corrupt Back Buffer?

  I have a fairly complex app that suddenly has been displaying what looks like a corrupt back buffer... as if the backing store for the window is confused about it's size or something. When the app starts everything looks fine, but whenever i mouse over any control that changes state on mouse over, the whole rest of the window gets corrupted with what looks like the right image render with the wrong "width" if you know what i mean. There are no errors in the debug output while this happens... Here's what it looks like before I mouse over the button: http://i126.photobucket.com/albums/p110/xamlgeek/notcorrupt.png And here what it looks like after: http://i126.photobucket.com/albums/p110/xamlgeek/corrupt.png ...Show All

• SQL Server SOULUTION The parameter is incorrect. (Microsoft OLE DB Provider for Visual FoxPro) after SP1

• Software Development for Windows Vista Worked on one computer now SqlWorkflowPersistenceService fails to persist on new computer.

  I transferred a state machine ASP.NET project from one machine to another. I created the persistence database from the “C:\WINDOWS\Microsoft.NET\Framework\v3.0\Windows Workflow Foundation\SQL\EN” SQL files. I changed the connection strings. Every time I run the web application nothing is persisted to the DB. No errors either. It has been running for months on the one machine with no problems. No code change. Any help would be greatly appreciated. Stan Thank you for responding! I am at a critical point now and really need to get this going.

• Windows Forms Keyboard cues problem

  Hello , Background: I've got a WinForms app written in C# using .Net 2.0. In this app I have a custom button class: public class ThinButton : Button The reason for having the class is to override the default painting. Specifically I want to draw a thin border and have a narrower margin between the button edge and the button text. This allows me to have a smaller button (to fit into tight places) that still looks good. The Problem: I have noticed that when I press the alt key on the keyboard (when running the app) the accelerator key mnemonics are shown underlined, as they should, for all controls, including my ThinButtons. When I press the alt key again, the mnemonics dissappear, as they should, for some control ...Show All
