• SQL Server unable to access "install windows components"

  I didn’t know where to put this so sorry if this is not the appropriate place. I am running Windows XP pro sp2 with visual studio 2005, ms sql server 2005, and a number of other applications. My problem is that I am not allowed to install new windows components(I want to install IIS). When I try to access from either control panel, add/remove programs, Install new windows components or directly from the winXP cd I get the following error in a pop-up form and I can only press "OK": "Another copy of Setup is already running. Complete the other Setup or restart Windows." I am not running the instance more than once. I do this as the first thing after a restart with the same result. When looking at the processes in the task manager I cant see ...Show All

• Visual Studio Tools for Office how to create a new Tools.Word.Document object?

  Hi Cindy, Thank you for your repply. There is another question: If I already have a ThisDocument class in a project, can I get its instance by passing a IRuntimeServiceProvider object to its constructor in another project If it is possible, what the IRuntimeServiceProvider is How can I get it I wrote a new class which implemented the interface, and return null in the GetService() method, but it was no use... Thanks, -Noah Hi, Creating code-behind objects such as Microsoft.Office.Tools.Word.Document directly from code isn't supported. Moreover, these types aren't remotable so you could not pass instances between projects since they would be running in seperate AppDomains. If you are try ...Show All

• SQL Server How to divide a row data to multiple row in one table by SSIS?

  Hi, Experts, I have a data table from a old system. There are 10 data fields stored in one row at this table. How can I seperate those fields into another table to be 10 rows Any component in Data Flow can I use (I have tried several component...) by the way, the original table is a large table, contain 3,000,000 rows. Thanks for your all assistance. If the Unpivot and Multicast options do not work for you then you could probably just do this in a custom or script component. Not sure why you think 30 million rows is too large, if that is the number of rows you should have then why it ian issue I don't get what you are trying to do. If you are still struggling with this then could you write som ...Show All

• Software Development for Windows Vista Changing default speaker configuration on Vista

  i am preparing application to test sound at different speaker configuration for windows vista and windows XP. for doing this i am using API SetSpeakerConfig() to set the different configuration and API GetSpeakerConfig() for getting same configuration. this is working fine in Windows XP. but not in Windows Vista. The call to SetSpeakerConfig() succeeds, but doesn't actually change anything. Is there any way other than by using the Sound control panel.

• Visual Studio Express Editions Problem with Tabcontrol

  Hello everybody! I ran into a problem using the .NET 2.0 Tabcontrol: I need to have the single tabs left-aligned instead of top-aligned, but when I set the alignment property in the visual designer to "left", something goes wrong with the control. Eg. the text displayed on the tab registers disappears and the whole control seems to look a little strange (can't point the finger on something specific though...). Without the text on the registers the thing becomes somewhat useless. So, is there a way to fix it or any kind of work-around Thanks a lot, Tobias Koerner Here's a C# port, unfortunately I have the same problems in the Designer. Perhaps OnHandleCreated() is not getting calle ...Show All

• Visual Studio 2008 (Pre-release) DATA BINDING: Problems attaching a ValidationRules and Converter to a Binding - BLOCKING

  I would expect this markup to invoke my validation object and in turn invoke my converter object. Any idea why its being ignored Actually, the converted is being called once for Convert, but never again. I do change the bindings for this control in code, so I'm wondering if the validation and converter mappings aren't updated by the binding. However, I do fire a PropertyChanged event on the original source property, so it should be picked up.

• .NET Development Problems receiving packets from socket

  Hello! I'm new in this forum and in this awesome programming language. I came from Java and I'm actually doing a speed learning in C#. We actually have a single problem that it drives us crazy. We are connecting a serial old device in a TCP/IP terminal server (with a special RJ45-RS232 cable). In fact, the device receives the petitions from the client and sends them the requests to its sender. The device, I said, is and old device that sends the values of patient parameters that we ask it to send. We, then, create a Socket from our computer to the terminal server (is a Lantronix Multiport device server) and make the process of connect to the device, ask the parameters and configure which parameters we want to receive and it starts to send ...Show All

• Visual Studio Team System Schema Compare - Plumbling for Transaction Support Bug?

  When I do a schema compare, I have 'Include SQL plumbling for transactional synchronization scripts' unchecked. IOW, I do not want my scripts to contain any transaction support. However, I've noticed in some cases, DBPro adds transaction support anyway. It doesn't do it for the entire script but only in those cases where DBPro decides to rebuild a table (such as when column orders in a table between source and target are not the same). Below is an example. This was generated with the Plumbling option turned off. Is this a bug Thanks - Amos. --------------------------------------------------------------------------------------------------------- PRINT N 'Rebuilding [dbo].[ProjectBillingSchedule]' GO SET TRANSACTION ISOLATION ...Show All
