• SQL Server Transactional Replication - Undistributed commands

  Hello, I have a publisher set up to transactionally replicate just one table which has about 19000 rows. The snapshot agent finished and everything was OK the first day. Now (day 2) the replication monitor estimates that latency to the subscriber = 10 hours and undistributed commands>600,000 and growing each minute. How could this be when data is only inserted into this table and it has <20,000 records Please advise...thanks! Some things I'd look at for a clue: 1) What kind of errors do you see in the SQL log or in the application log that might be causing this 2) Is the subscriber on a different server Have any permission changes occurred with that server 3) Do you see anything that m ...Show All

• Visual C++ Confusion with header includes

  Hey guy, Well I have recently just been exploring Visual Cpp and im sort of catching on but theres still a slight problem I run into with header includes. When I make a window form application I never now what headers to put in my programs for certain stuff. All I know is that for console applications you need the iostream include. Is there a list of header includes around here what explains the functions and procedures held in each one Thanks Keen. Hi Keen I would suggest that you get a very cool book called C++ Primer Plus, Fifth Edition by Stephen Prata. I am like you a C++ n00b but I have been finding this book of great help. It talks you through all C++ fundamentals and really makes sure you u ...Show All

• Visual C# What is "\n"? Any difference from "\r"?

  I know "\r" indicates a sentence break. Then what about "\n" HtmlText = HtmlText.Replace( "\r\n" , "\r" ); HtmlText = HtmlText.Replace( "\n" , "\r" ); HtmlText = HtmlText.Replace( "\r\r" , "<p>" ); HtmlText = HtmlText.Replace( "\r" , "<br>" ); In the above line, since "\r" is to changed into "<br>", why should not directly change "\n" and "\r\n"directly into "<br>" http://west-wind.com/weblog/posts/1499.aspx The 1st statement replaces a DOS end-of-line to a \r, the 2nd replaces a Unix end-of-line to a ...Show All

• Visual Basic Visual Basic Sendmail function.

  Visual Basic Sendmail function. I want to amend a script so that it sends .xls attachments by e-mail to two or more recipients. Here's the version that sends to only one: ActiveWorkbook.SendMail Recipients:="Ken.Tun@xyz.co.uk", Subject:="Insert as required", ReturnReceipt:=False But I also want to send to e.g. "Stan.More@abc.co.uk" According to VB Help it is possible:- "Recipients: Required Variant.

• Visual Studio same problem

  A requirement of my reporting system that I'm developing is that it be possible to localize the reports.  They don't need to be localized dynamically -- we can provide different RDL files for each language and report combination. When I put japanese characters into the RDL file I get mixed results. When I export to Excel, it exports fine (except for the chart labels). When I export to PDF, I get the following error: A call to PInvoke function 'Microsoft.ReportViewer.Common!Microsoft.ReportingServices.Rendering.ImageRenderer.CompositionPDF+WindowsGDIWrapper::GetGlyphIndicesW' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention an ...Show All

• .NET Development XmlAttributeOverrides and renaming elements

  Hi, I'm using xml serialization to create an xml file, however I need to change some of the names of the xml elements that will be generated (actually I only need to make them all uppercase, don't ask!). I can't change the class that is to be serialized as it has been autogenerated, using xsd.exe, from an xsd I also cannot change. XmlAttributeOverrides appears to be the answer and I have changed most of the elements, however, there are a few elements that I'm having trouble changing. I would love to post some of my own code here but I'm struggling to condense it into something manageable, so I'd like to use the example on http://msdn2.microsoft.com/en-us/library/system.xml.serialization.xmlarrayattribute.aspx .

• Visual Studio 2008 (Pre-release) Items.SourceCollection is not flushed when binding is removed/cleared.

  I am calling ClearAllBindings and then Setting a binding to a new collection, but the old collection data is hanging around in the ItemsControl. 2 Problems 1) After I call UpdateTarget, the data from the new binding/collection is present, but the Items.SourceCollection still contains the contents of the initial collection. I would expect not to have to manually manage the contents of an ItemsControl from the context of a source object.

• Smart Device Development How to save and re-use listbox values?

  I need to understand how to best save listbox values when I leave a form, and later reload those values into the listbox when I go back into that form. Note that my program is running in a CE environment, so I need to be careful with resources. I have a text box (txtScanBale) where the user keys or scans in numbers, one at a time, and as he does, I save each entry in a listbox (lstBales), with the most recent entry at the top, using this code: Me .lstBales.Items.Insert(0, Me .txtScanBale.Text) If Me .lstBales.Items.Count > 200 Then Me .lstBales.Items.RemoveAt(200) End If And, as shown, I limit it to the 200 most recent entries. But when I leave the form, the listbox values all go away (as far as I know), beca ...Show All
