• SQL Server Unique, key/keyref Schema Support

  I was just wondering if anyone knew why SQL Server 2005 explicitly rejects schema sets with schemas that have xs:unique or xs:key/xs:keyref declarations. It seems like a fairly basic schema feature. Any ideas about when that support might come along Thanks, - Erik I second Galex's recommendation to file a request at http://connect.microsoft.com/SQLServer . One of the reasons why we currently do not support it is that the language used to constrain key/keyref is based on XPath 1.0 and we do not plan on adding an XPath 1.0 query engine at the level of XQuery.

• SQL Server Will DST issue affect SQL Server?

  Does anyone know if SQL server 2000/2005 will be affect by the DST issues in 2007 If it is, is there a patch release by Microsoft SQL Server relies upon the host computer clock for the correct time. DST issues are temporal, and only effect you if you think it does. SQL Server does not care about the time -it just stores whatever value it is told. So, if DST is a concern for your business, then perhaps you should consider using UTC time rather than local time when you store time values. ...Show All

• Visual C# Need CCW to support [hidden] and helpcontext

  I have a C# project that exports part of its API into COM using regasm. I need the API to include features that don't seem to be well documented. These are: [hidden] - I need to mark certain properties/methods hidden in COM. I realize that no such concept exists in C#, but it does on COM. [helpcontext] - How do I support context-sensitive help This includes helpcontext, helpstring and helpfile. Note that this is not a graphical API or GUI control. It is a library implementing a set of interfaces. Searches around MSDN and Google have revealed no answers so far. Hi Mattias, I like using MIDL too. Not just to make it hard to change the COM interfaces but also to allow MSFT interfaces to be used that ...Show All

• Windows Forms Format MessageBox Text

  Using VS.Net 2003 Yes, haven't upgraded here at home yet, only at work... cost $ :P But, not sure if this is possible. A MessageBox: string message = "Delete " + lblTitle.Text.ToString() + " "; MessageBox.Show( this , message,.............); Is if possible to format the lblTitle.Text above Bold, underline, color, or anything will do.

• Windows Forms Fire events outside the form (KeyPress)

  Hi, I need to know how can I be able to fire an event outside of my form. We all know that there are lots of events that are fired by some action of some control or the form, such as Form1_Load, Form1_KeyPress, Button1_Click, Timer1_Tick, etc..., but to be more specific I really needed to (sort of) fire the KeyPress event outside the form. Let me simplify this: Suppose I have a form with a textbox, and I have the Form1_KeyPress event to capture the keys I press within the form, and individually transforming them to different keys, by changing the content of the e.KeyChar value while the KeyPress event is running, thus changing its output. To put it simple, the program basically transforms the pressed keys into different ones. For examp ...Show All

• Visual Basic HScroll

  In switching from VB6 to VB2005, the Scroll bars have apparently changed. The Scroll part works, so I can change a program parameter based on the position of the cursor of the Scrollbar (or using Mouse clicks). I then want to apply the new value, but only at the end of the Scrolling. There is no "MouseUp" available for the HScroll. The "Mouse hover" does work, but it causes unwanted events. Is there a way (after dragging the cursor) to apply the final value - after releasing the cursor I can do it by pressing another button, but that is too late for some cases. Also, is there a way to change the backcolor and forecolor of Scollbars Has anyone found a solution to the no mouseup event problem. I have tried to ...Show All

• Visual Studio Setting working folder with subfolders

  VSS v. 8. Working folders can sometimes get out of whack, if you change development directories on your machine, make a mistake, or whatever reason. The first time you set a working folder on a folder in VSS, it "takes" for all subfolders as well. However if you set a working folder for a subfolder, there seems to be no way to go back to a root folder and reset the working folder and have it "take" for all subfolders as well. At this point, you have to go into each subfolder to change it, which could be enormously tedious. Any way around this thx I was able to fix the problem by going into the ss.ini file for my user name and deleting all the entries of the form [...] Dir ...Show All

• Visual Basic Recieving 'i??' character symbols when loading text files not containing them

  I am writing a cross-platform application and I am using Visual Basic 2003 Standard for the Windows XP version of the application. My Windows Mobile version writes information out to a text file and my Windows XP version can load and modify them. The text files do not contain the i symboles, but when I load the text files into my Visual Basic application each file loaded has those symbols attached to the begining of the first line I read into my XP application. Does anyone know why this is happening At first I thought my Windows Mobile Program was the culprit but considering the fact that those symbols are not in the text file when I view them (I used 3 different text editors to make sure) so I am assuming it's something I need to ...Show All
