• .NET Development TCP Server

  I have To create a TCPServer application where my server waits for clients connections. Clients are POS terminals. I get a network stream of data where I first have to check 1st byte of data and look for a STX - Hex(2) in it. And if it exists then keep reading the stream untill i get an ETX - Hex(3) .

• Visual Basic Visual Basic 2005 IDE Performance Hotfix Released

  We've received feedback, both directly from developers and in the forums, regarding slow performance of the Visual Basic 2005 IDE in certain situations (larger projects, projects with many errors, etc.). I’m sorry that these issues made it to production and degraded the performance of the IDE. The Visual Basic Performance team is working hard to address these issues via hotfixes and the upcoming Visual Basic 2005 SP1 while we work on engineering changes to make sure that issues such as these never make it into a shipping product in the future. Based on this feedback and forum posts, we've been working with customers to address these performance issues. We recently released a performance hotfix to address the follo ...Show All

• SQL Server Question on Internal Activiation

  Hi Could it be assumed that a stored procedure, activated internally by Service Broker, is executed under the same environmental variables (resource allocation specifically) than when that same stored procedure is executed via an EXEC statement from a non-Service Broker procedure When I have 10 of these procedures running (somewhat concurrently) overall performance is not even close as to when I let Service Broker activate the procedure via 10 messages on the queue. If all variables are equal than I am not sure why this is. Or is it possible that everything is not equal Thanks Paul Are you certain that all 10 are actually firing up at the same time via SSB   It's possible tha ...Show All

• Visual C++ VS .Net 2005, how to disable intellisense...

  Hi I am really frustrated with the performance of VS .Net 2005. This is because I always see at the bottom "updating intellisense..." and it uses 60% to 70% of CPU. How to disable this updating of intellisense... Please this is making Visual studio unusable. Thanks Chandra I have the same problem (and may be working for the same company)  My solution has more then 30 projects consisting of a total of >2500 cpp files.  Each project runs a makefile in the pre-build event that automaticly builds header files from cpp files based on information in macros imbeded in the cpp code. Each cpp file contributes to up to 4 header files so if the solution were searched the same defini ...Show All

• Windows Forms display member of checkedlistbox

  I want to use a checkedlistbox for users to check which record they want to select. Can I show the full detail of record(serveral fields) instead of a single field I think using a datagrid view is overkill if all you want to do is have a bound checkedlist box Although it does not come up in the intellisense the following seems to work fine for me Me .ChListGroups.DataSource = ds.Tables( "Groups" ) Me .ChListGroups.DisplayMember = "GroupName" Me .ChListGroups.ValueMember = "id" ...Show All

• SQL Server Script tasks don't work in Production

  Hallo, In SSIS Version 9.00.2047.00 I have build a few packages using script tasks. These packages work well in development. When I try to run them Using DTUtil the systems displays in the Package Excecution Progress-window the message: 'Error: The tasks "reading registry" cannot run on this edition of Integration services. It requires a higher level edition.' Emptying the script task from its variables and script doesn't make a difference. I did not find an explanation in BOL. Concerning script tasks I only find The Script task uses VSA as its engine for writing and running scripts. To run a script, you must have VSA installed on the computers where the package runs.

• Software Development for Windows Vista Problem because of Vista registry virtualization

  Hi, I have a problem under Windows Vista. I can't determine if a user have permissions to write in a specified registry key. When opening a key via the RegOpenKeyEx function, a valid key is returned, but this key is virtual. I need to know how to determine whether a user has permissions to open a specified key without virtualization. Thanks First I'd like to make sure that this is not used to make an administrative check. The proper way to check for members of the administrative group is to use CheckTokenMembership. Otherwise, you have couple options: * Get the security descriptor of the key and use AccessCheck. * Make your application Vista aware by specifying an explicit run-level in ...Show All

• Visual Studio 2008 (Pre-release) WCF Proxies different depending on binding

  I'm not sure if this is the right forum for WCF questions/comments, but here goes one anyways... I created a "Hello [Name]!" WCF service and hosted it in IIS by defining creating a web.config as explained in the WCF Hands On! book by Craig McMurtry. The web.config file was originally using "basicHttpBinding" and I genereted a proxy for it which was quite simple to follow. Then I changed my client and the service (by changing web.config) to use "wsHttpBinding" (which encrypts the message) and it worked just fine (and it did encrypt the message). Once thing to notice here was that I was still using the proxy that was generated when the binding was basicHttpBinding. Next I added a new method to my service and regener ...Show All

• SQL Server SQL Server 2005 SP2 CTP web parts and Sharepoint integration mode.

  My question is related to the setup of this environment when you are starting from scratch.. It seems that the report list web part takes an reporting services ReportManager URL, but since the reports I added end up in a sharepoint store, it seems there is a disconnect. I am missing something or are these web parts specifically geared towards non-sharepoint mode usage Another question is related to the reportViewer webpart - Does this webpart implement the IReportViewerMessages interface Is there a way that I can leverage this so that I can use it for a multilingual site and change language based on locale thru this interface thanks for any help on this.
