• .NET Development Parameter in aggregate function

  Hi, I'm having this little weird problem with Visual Studio. It doesn't seem to accept the param in the aggregate function: SELECT Avg(Rating), DateDiff ('m',RateDate,@RefDate) FROM qryRating GROUP BY DateDiff ('m',RateDate,@RefDate) Visual Database Developer returns an error saying: "you tried to execute a query that does not include the expresion DateDiff ('m',RateDate,@RefDate) as part of an aggregate function". Explicitly replacing @RefDate with any literal (or even function like Now) works, but not with the param Does anyone know why Thanks. Not sure if provider would support parameters ffor GROUP BY, but do you pass same parameter twicw or once You need to pass it twice if it is inline query and ...Show All

• Visual Studio Express Editions Command line build using VCBuild

  Hi. I have a few questions/comments about command line build with Visual C++ 2005 Express Edition. 1. I have noticed that there is no 'devenv' in the Express edition (I got used to it in the VS .NET 2003 version). The IDE executable is 'vcexpress', but it seems it has no command line build capabilities. I assume command line builds are to be done using 'vcbuild'. Am I right 2. Running 'vcexpress / ' brings me a confused explanation which is a mix up of 'vcexpress' and 'devenv' which does not exist in the Express edition. This is clearly a defected help message. 3. If I want to use 'vcbuild' for building Win32 applications (after installing the Platform SDK), I also have to change the PATH/INCLUDE/LIB directories in the %VS80COMN ...Show All

• Smart Device Development uninstall device emulator version 1.0 beta 2

  I am uninstalling vs2005 beta 2, and there seems to be an order that I should've uninstalled in but I didn't find out until afterwards. Now this device emulator software is stuck, installed on my computer and I can't get it off because it's asking for an msi file on a dvd that I don't have I know this thread is very old but nothing I've found on the web works for uninstalling this program which is preventing me from upgrading to the .net framework 2.0 I've tried the .net uninstall tool - it can't find the proper MSI. I've tried the standalone package - it's a different version so pointing the uninstall to this MSI doesn't work. I've tried everything on the msdn blogs. What I need is to so ...Show All

• Visual Studio Express Editions indexed types inside class

  I am trying to create my own data type. Inside that class I used List<>. I have set it as private and than I have used property to access it. The problem is with accessing values inside that list.

• Visual Studio 2008 (Pre-release) How to access attached properties programatically?

  I am creating a rectangle programatically in a control and I want to be able to position the rectangle at a location relative to the Canvas Top and Left. The control is a Canvas and the rectangle is one of the Canvas' children. In xaml I do this with, e.g. Canvas.Top="5" but how can I do this programatically The rectangle does not have a property Canvas. I'm guessing that I have to use an attached property to the rectangle or is it part of the control's properties which in this case is the parent Canvas Thanks for any help. Or you can call SetValue(Canvas.Top, someInt) and SetValue(Canvas.Left, someOtherInt) That's how you normally set an attached property, the same way you set a normal ...Show All

• Visual Studio 2008 (Pre-release) How to retrieve the client machine name from within a WCF service?

  I have a WCF self-hosted service that use netTcpBinding and basicHttpBinding. Is there a way from within the WCF service to retrieve the machine name of the client that has called the service There isn't a standard way that works across every transport to do this. For instance, the TCP protocol doesn't include the client's machine name so there is no way for us to expose this to you. You may want to consider updating your contract to include the machine name as a parameter, or consider adding it as a message header on the client. Regards, David ...Show All

• Visual C# Properties in C#

  Hi all, I've read about properties in C# and it is my uinderstanding that they are here to replace the 'setter' and 'getter' methods we all used have to manually create. BUT I cant create these for private variables. In the following: class MyClass { private int x; public int X { get { return x; } set { x = value; } } } Private int little x is 'getted' / 'setted' through public int big X. (e.g. MyClass.X = 10) If big X is public and little x is changed through big X, what is the point of having little x as private We could just have little X as public and remove bi ...Show All

• Visual FoxPro Can't rebuild project after moving from VFP7 to VFP9

  I have several large projects that I developed in VFP7 under Windows 2000 server. I have copied them entire to a new server and I'm trying to convert them to VFP9 to run under SQL 2005.
