• Visual C++ [c++/CLI] create a wrapped managed dll for purely unmanaged code

  Hello, I am trying to create a dll that internally uses managed types but exposes a plain unmanaged interface. (vs2005 beta 2 - c++/CLI) All the managed stuff shall be "wrapped out of sight". So that I would be able to use that dll from pure unmanaged code (for example inherit from classes in that dll) that has no /CLR flag set. Is something like that possible. I heared something called ManWarp tried that approach. If it is possible, how can I do that. Maybe there is a small litttle sample project around Use #pragma unmanaged. Write a function that uses your managed stuff and exposes its name via extern "C" either witj declspec exp ...Show All

• SQL Server SSMS scripting Stored Procedures to separate files

  I have noticed that in (SQL Server Management Studio) SSMS the ability to individually script stored procedures appears to have been removed (it was there in Enterprise Manager (SQL Server 2000) and I found a comment in another thread which appears to confirm this: Steven Twitchell wrote: >We've had several requests from various sources for functionality to script objects to their own files rather than one large file. I have been scripting stored procedures to individual files and then using sourcesafe to compare databases to ensure syncronisation with a client. I can do this on one file but it does not give the same granularity ...Show All

• .NET Development .NET bug? - The Undo operation encountered a context that is different from what was applied in the corresponding Set operation.

  Hello, I have tried to find a solution for this problem but so far have not found anything that applies to my exception.

• Visual Basic Works in SP1 but not in SP2

  My company has an ActiveX control on its CUSTOMER ONLY website that captures customers' pc information, such as OS, all hardwares and all the software installed. In another word, everything is captured. Customers will have to log into the website and allow the ActiveX control to be installed and run. It will automatically send the data back to the server and the server will save it into the database. This worked well in Windows XP Service Pack 1. When the company upgraded all our customers pc to Windows XP Service Pack 2, an error "Run-time error:'70' Permission denied" appeared. And the activeX control failed to work.

• SQL Server Need a list of Error Code

  Hi, When we configure a transformation to redirect the error record, SSIS gives 2 columns: 'error code' and 'error column'. In one article, I have seen how to get the error description using the 'error code'. My questions are, Where I can get list of all possible error codes 'error column' gives the id of the column. How to get the name of the 'error column' Thanks.

• SQL Server Making outbound HTTP requests from SQLCLR

  Hi, I have written a C# console application that adds a message to a SB queue and a C# stored procedure that reads the message from the queue. I have had so many problems that I'm beginning to doubt the usefulness of this, but that is probably just my frustration speaking. I am stuck on putting an XML message into the queue and reading the XML in the stored procedure. The console app has a simple object called Message. This class has 2 fields, a guid and a string. I serialize the object into XML using XmlSerializer. This results in an XML string that looks like this: < xml version="1.0" encoding="utf-16" > <Messa ...Show All

• Visual Studio Express Editions Is vc++ 6.0 good

  i bought a book on vc++6.0.can i build powerful software applications with that.what is the difference between the vc++6.0 and vc++ 2005.what is the latest released version Well... you could use VC++ 6.0 but that's too old really. VC++ 6.0 was released about 8 years ago and I'd say that the quality of the C++ compiler and the IDE itself improved a bit since then . Not to mention that there is a free version of VC++ 2005 called "Express" (though it does not have support for MFC and ATL) see: http://msdn.microsoft.com/vstudio/express/visualc/ ...Show All
