• SQL Server SQL Server 2000 and SQL Server 2005 on the same computer

  Hello. Is it a possibility to install two different instances on the same computer, one from SQL Server 2000 and another from SQL Server 2005 I've installed first SQL Server 2000 and I didn't want to upgrade it to SQL Server 2005. I don't want to upgrade SQL Server 2000 to 2005, because I'm working at two applications who uses different instances. Is there possible to appear conflicts between SQL Server 2000 and 2005 on the same computer ...Show All

• Windows Forms Better practice to load Form with data?

  Hi, I have a form which suppose to load with data. There is a web service to catch the data after instantiating the form. This causes loading time to be slow. There is no problem for the slow time but i want to show the form after populating, not while populating  with data. That means i need to take something like a buffer, load th ...Show All

• .NET Development XPath and case sensitive problems

  Running xpaths against a xml doc (comming from a mssql server) and having trouble with case sensitive letters. I have tried to use the xml translate funktion, but it would need an exact match in the DB anyway. If I look for the name John and it is typed JohN in the DB I get nothing. Is the only solution to 'wash' the data in the DB. Are there any work around to make a xpath query non case sensitive  XPATH 2.0 (next version) has functions to deal with case-insensitivity, but unfortunately the current version does not. Your option is to try to incorporate a 3rd party solution such ...Show All

• .NET Development Gridview need help

  Sorry for posting this in the wrong forum - but cant find a forum for Web.UI controls. If someone knows of a good forum for asp.net web ui please post as it. I have a GridView component in which I have defined a "delete" configured CommandField. When selected, the DeleteCommand of the configured datasource calls a stored procedure to delete the selected record. However the deletecommand is firing twice. There are no pre/post delete events defined for the GridView or the DataSource. When the ButtonType for the "delete" configured CommandField in the GridView is set to Image the DeleteCommand always fires twice. ...Show All

• Visual Studio Designer Issues

  I have been playing with the latest CTP drop of VS2005 (Feb05).  So far the Class Designer is one of the neatest tools I've seen.  However, I am having a little trouble figuring out how to use it.  For instance, I want to build a custom collection that inherits from the collection class.  How do I do that   I see the Inheritance tool, but how do I get the base collection class on the designer   So far I've just been manually coding inside of my classes the "inherits collection".  Also, what is the 'Association' tool for Hi Jon, We are glad you like the Class Designer. You can create a custom ...Show All

• Visual C# generics constraints for types implementing operators

  I'm trying to build a class public class SignalBuffer<T> where T is any type that implements the + and the * operator (mostly double or my own complex number type ) How can I add a constraint to SignalBuffer that constrains T to types implementing these two operators I tried just using public class SignalBuffer<T> where T : double, Complex but of course this won't compile because you can't use double in a constraint Another thing I don't understand is why it is possible to make generic methods like this public myType myMethod<T> ( T var1, T var2 ) but not generic operator overloads ...Show All

• .NET Development Multiple web services......

  Was looking at setting up a central machine on our network to provide our web services. Since the services will be coming from different parts of the org, I will have many installed (more than 2 or 3). Instead of creating a web reference to each separate service, I was wondering if there was a way (Im pretty sure there is) to create a web reference to the central web service machine, and then when I need to declare an object of one of the web services, I would just declare the object pointing at that reference, and then IntelliSense ( ) would give me a list of the services on that machine. I havent been able to find exactly what I needed onl ...Show All

• Software Development for Windows Vista VS6 C++ Compile error using "GetAddrInfo"

  Hi, Windows XP SP2. Platform SDK recently downloaded. VS6 C++ SP6. I am using the 'GetAddrInfo' function ( DLL Ws2_32.dll) Header ( Ws2tcpip.h) When compiling I get the error "c:\program files\microsoft platform sdk\include\wspiapi.h(45) : error C2265: '<Unknown>' : reference to a zero-sized array is illegal " I believe there is some 'compatability' issue between IPv4 and IPv6 functions !! Not sure how to sort it though. IS it because the SDK stopped being compatible with VS6 sometime ago Can anyone offer some ideas for what is I believe a not unique issue ! Thanks, Jon.

• Visual Studio Tools for Office Required software to install on Web Server for VSTO?

  Greetings, I know there are a number of posts that discuss deployment issues, but I was not able to find one that explicitly addresses this question. It is stated in the Microsoft Documentation that there are a number of required software prerequisites (.net 2.0, vsto runtime, interop, etc) that the end-user machine needs to run a VSTO 2005 application (regardless of whether it was deployed locally or through network). My question does not pertain to the end user but rather the server, assuming a pure network based model, where the end user is accessing a web server. So my question is: Are there any software prerequisites that are required ...Show All

• Software Development for Windows Vista UISpy missing from the February CTP

  UISpy is missing from the February CTP release of the Windows SDK that Microsoft recently published externally at http://msdn.microsoft.com/windowsvista/getthebeta/default.aspx This was due to a miscommunication between me and the Windows SDK team. Unfortunately, the January CTP release of UISpy will not work wtih the February CTP UIAutomation dynamic link libraries (DLLs) because the assembly versions have changed in the February CTP release of these binaries. The UISpy executable that ships with the January CTP release refers to the version of the UI Automation assemblies from the January CTP release. Our team has corrected thi ...Show All

• Smart Device Development Use of IsProcessorFeaturePresent() to detect specialized hardware

  I came across a bug report (FDBK26623) that mentioned the removal of compiler switches to enable intrinsics.  I thought I'd follow up.  You can use the IsProcessorFeaturePresent() API to determine the architecture or the existence of specialized hardware, such as DSP.  e.g. IsProcessorFeaturePresent( PF_ARM_DSP ).  This allows an executable to take code paths on the condition of this call.  In response to the original bug report, the problem with preventing the use of certain intrinsics during compilation is that: 1. it doesn't prevent the symptom from occuring (you can still run the executable on incompat ...Show All
