• Visual Studio 2008 (Pre-release) Object-oriented network database

  Hi, All! I am Ukrainian scientific researcher and developer. I am developing object-oriented network knowledge database which is based on object-oriented database engine.

Now I have to use three fields to store object soft pointers. One for object handle; One for wrapper instance to pin the object instance in memory; and One for instance of user object. I want to hide implementation details from end user. To make this I need some kin ...Show All

• Visual Studio Express Editions Deploying a web site

  hi, I created a web site using VWD 2005 I copied the files in the web application folder to the web domain. when I try to open the *.aspx files, I get an error tells me the file(s) doesn't exist. a *.htm extension in the same place will work without problems. but my web application won't work. another issue, there doesn't seem to be anyplace where you can opt between debug and release build. debug is default and no other options are available. based on this informaion, it seems I am not allowed to debloy an application made with VWD 2005.

• SQL Server Deploy to SQL Server or flat files

  I'm in a quandry about how to deploy my SSIS packages and was hoping someone has some experience of the same. There are 2 approaches: 1) Deploy to SQL Server. 2) Deploy to .dtsx files. I suppose the default approach is to deploy to SQL Server however I have a problem with that. My packages contain Execute Package Tasks which use different connection managers depending on whether the package that they are calling is on SQL Server or in a .dtsx file. That means that my packages have to contain 2 connection managers for each Execute Package Task - one for pointing to a package deployed to SQL Server and one for a package tha ...Show All

• Visual Studio Msgbox On Windows Server 2003

  Hi Guys, I'm really new to .Net development and need your advise on this. Recently I've completed a web application using VB.net (Visual Studio .Net 2003). In the application whenever the user clicks the delete button, a msgbox will appear prompting the user to confirm the deletion via the Yes or Cancel button. On my own machine (Win 2k IIS5), the msgbox appears without any issues. However when I deploy the application on a Windows Server 2003 machine, the msgbox will not appear and a event will be captured in the system log as "Application Popup" containing the text that I wanted to display (e.g. Do you really want to delete this user rec ...Show All

• Visual C++ How to link to the correct STL library when a third party dll is based on VC6?

  I have a third party dll targeted for VC6 and .net 2003. It worked well with my old MFC application. After it was migrated to VC 2005, it throws an exception of access violation whenever the stl string information in the object is accessed. Accessing other members of the object is OK. I guess it might be linked to the stl.net library instead of the old stl library that the dll is based on. Anyone knows what is the problem  and how it can be solved   Thanks. Please post more details inlcluding a simple repro case reproducing the issue so that folks on the forums can help you. Thanks, ...Show All
