• Visual C++ Debug Runtime removed from VCRedist in BETA 2 (CTP August)

  Hi, I need to remote debug my debug bits on a test machine (due to hardware configuration). Using the original BETA 2 or July CTP this wasn't a problem; the debug runtime was installed by the vcredist.exe. However the debug runtime seems to be removed from the redistributable in the August CTP. Any ideas, how I can install the debug runtime on my test machine A simple file copy of MSVCP80D.dll and MSVCRT80D.dll does not work. Thanks, Thomas PS: It's a COM component and the registration fails with ".... This application has failed to start because the application configuration is incorrect......" ...Show All

• Visual Basic Add connection wizard fails with Access database

  I have the RTM version installed. I am quite puzzled at this wizard. It works fine with SqlClient. But for Access databases, this wizard completely fails. In this wizard, I only have one option to do - setting the ConnectionString. I set it to Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\path\abc.mdb, which works fine in my code. But when I click OK, it complains: --------------------------- Microsoft Visual Studio --------------------------- Format of the initialization string does not conform to specification starting at index 0. --------------------------- OK   --------------------------- And more, the Advanced button is dis ...Show All

• Smart Device Development Seeking System.Runtime.Serialization alternative for Compact Framework 2.0

  I’d like to create a light version of my .net windows application for mobile devices using Compact Framework 2.0. The .net windows application load and saves data files using System.Runtime.Serialization and formatting the files using SOAP, which so far works great. I’d like to keep interoperability between the windows application and the mobile version by saving and loading the same data file into the same data model. Looks like the Compact Framework 2.0 does not support System.Runtime.Serialization like .Net Framework 2.0. Does anybody have a solution for this problem Or any idea I could explore. Thank you, ...Show All

• SQL Server Release database lock

  Actually I'd like to know how I got the lock and then you can tell me how to release it. Here's the problem (this is sql server 2000 with visual studio 2005) I have a windows service that wakes up every 5 minutes and does some database work (reads rows from a table, process them, inserts them into another table). When the inserts are complete, the process should (I would think) release the database lock, but it doesn't. The database is accessed via a dataset object and that object is disposed of via the using/end using statement. Is there something I have to put in the connection string to avoid this behavior Thanks, Bob ...Show All

• Visual Studio Dynamic RDLC

  I have about 100 reports that I am converting from Crystal to MS reports.  I would like to be able to use a standard header and footer for these reports. I am trying to write code to add in the nodes for PageHeader & PageFooter at runtime and whatever else I need to stick in there including images.  So far I am having trouble getting this to work. I am reading in the report from the manifest stream and making a copy (so that it will be writable). Then I read the memory stream into an XML document and manipulate it. Then I save the XML document back to the memory stream.  The page footer still does not show up (O ...Show All
