• Visual C# Join W2K Domain

  Hi, how can i join a Workstation to a W2K3 Domain with a C# Prog Please post a code sample. Andi One way would be to use an instance of the WMI class Win32_ComputerSystem and the JoinDomainOrWorkgroup method of that class. The method itself is described here http://msdn.microsoft.com/library/en-us/wmisdk/wmi/joindomainorworkgroup_method_in_class_win32_computersystem.asp To invoke the method, first get the right instance ofWin32_ComputerSystem http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemManagementManagementObjectClassctorTopic3.asp The sample at that page creates an instance ...Show All

• SQL Server Query Designer in SQL 2005 Mgmt Studio a let-down?

  Greetings, all. Thanks for all of the great postings in this community. However, one question I have doesn't seem to have been addressed. In SQL 2000 Enterprise Manager, a user could right-click on a table, and choose Open Table>>Query. This option brings the user directly to a query designer very similar to the query designer available in SQL 2005 Management Studio. However, I have been frustrated by the following: - The Open Table option in SQL 2005 returns data immediately where the SQL 2000 Query option did not, meaning it opened faster and did not risk locking any records in the table - In SQL 2005 the user needs to click ...Show All

• Visual Studio Express Editions How do I test for null date in SQL table?

• Visual Studio Team System Add new Work Item type to existing project

  Is there a way to add a new work item type to an existing project We customized the CMMI template and added a new type prior to project creation. Now after having used it for a while, we have identified the need for another work item type. How can one do this Thanks in advance. Bernie The Team Explorer comes with a witimport (work item import) command line tool. The tool is located in the \Program Files\Microsoft Visual Studio 8\Common7\IDE directory. Using witimport you are able to upload new work item type definitions into an existing project. Hope this helps! ______________________ ...Show All

• .NET Development SQL Server not compatible with .net Framework x64?

  Hi. I'm trying to install SQL Server Express in a Windows XP x64 Pro. I got a message that tells me to uninstall .net Framework and all SQL components and reinstall .net Framework but I don't know where the cleanup wizard is at and because I've got Express, I didn't get it in a CD. So is it true that SQL Server Express is only compatible with .net Framework x86 which is not compatible with WinXP x64 Hi, The Product feature comparison page shows that SQL Server runs on a x64 Windows OS using WOW layer. So it should work although it will still run as a 32-bit app. I think the final version of SQL Express would work - the Beta/CTP releas ...Show All

• Windows Forms Chinese characters in a C# windows form

  I need help displaying chinese characters in a windows form. I have a web-based application written in C# that uses an embedded windows form control. To test chinese language support I cut and pasted some chinese text from a news site. The text is supported correctly throughout the web application. This includes storing it in a SQL database, retrieving it and showing it on web pages. But if I take the same text and put it in a windows form it comes out as square boxes. I need help with this. I do not have east asian font support installed so I don't understand why it shows at all. One interesting thing is that if I put a breakpoi ...Show All

• Visual Studio 2008 (Pre-release) Drag & Drop Operations

  Hi there. I'm on charge of implementing Drag & Drop operation for my WPF client. I found a class DragDrop which does it. I have a couple of questions to whom which used it. 1. How do I replace a drag image I know hoe to disable default cursors - from within QuearyContinue. Effectively I need to copy a bit of my screen and use it as a drag image - so I’m looking for smth. like bit blaster in WPF if exists (this problem get solved when I go for physical moving of the UI element I drag). 2. It appears that MouseMove event isn't firing until the drag operation gets completed (which stands to reason). That means that I have to handle a ...Show All

• Windows Forms Capture KeyPresses with one control, but handle them with another

  Hi, I'm creating a usercontrol which has a child property of the type Control. The UserControl has custom code for the KeyPressed event, and will handle keys like UP, DOWN, ENTER, etc... The remaining keys should be forwarded so they can be handled by the childcontrol. My first attempt was to use: this.child.Focus(); byte[] b = new byte[] {(byte)e.KeyValue}; string sendtext = Encoding.ASCII.GetString(b); SendKeys.SendWait(sendtext); this.Focus(); but it's just ugly and it doesn't work very well. Can someone suggest a better way to achieve this There is a keypreview property on a form, if it exists on a cont ...Show All

• Windows Forms Background worker and closing a form

  I have a form that uses the BackgroundWorker component (C# 2.0) to do a series of jobs in a very long running loop. I am running into a senario where the windows form is closed by clicking on the "X" in the upper right hand corner. This of course is fine but I want to make sure that I exit the loop gracefully. Is this good enough private void Form1_FormClosing( object sender, FormClosingEventArgs e) { this .backgroundWorker.CancelAsync(); } I am watching for the CancelPending in the loop but I am only looking for it about every 4 - 5 seconds. How can I guarantee that the BackgroundWorker thread has a chance to e ...Show All
