• .NET Development ConfigurationManager not recognized

  I am using VB.  I added a reference to the System.configuration library, and I still cannot use the ConfigurationManager namespace. This is very strange. I can't think of anything except a silly mistake I made some time ago, when I accidentally named a class of mine System and everything stopped working! It took me about an hour to find out what was the problem! ...Show All

• Smart Device Development Cannot start debugger

  Hello, I have been using VS.NET developing Pocket PC applications for over two years now, but all of the sudden I can no longer interactively debug apps running on the emulator.  Everything seems to start up fine - Emulator starts up, initializes, .NET CF installs, app under development installs, then... nothing (Output window in VS says "Launching Application").  I can start the application on the emulator by navigating to it using the File Explorer, but cannot debug.  How can I get my ability to debug back Thanks, Hi Mitchell, Are you using Visual Studio 2003 and NETCF v1.1 SP3 to deb ...Show All

• Visual Studio 2008 (Pre-release) Why will LINQ fail ?

  Microsoft tries to helping object developers to close the gap between the relational world and the object world.And they call this " object modelling approach " Dlinq. Using " custom business entities " in enterprise programming with Dlinq might seem the best thing after " sliced bread " but it isn't. For my part I have written my Mappers and used commercial OR/M tools. They mostly provide the same thing. __Read the table from the database. ___Put that into a some HELPER thing.( DAO,DAL,ORM) ____Put that into your custom business object _____Read from your business object.(if u can :) ) I see NO REASON for this " Unnecessary Pull ...Show All

  I created a VSTO Outlook Addin.  With the setup project that was created for me I created a MSI file that is run on all the user workstation as an local admin since users can not install software on their machines.  During the install I pick All Users and the install completed successfully.  I see my addin in Outlook and the addin works fine.  Every other user that sign on to that box for the first time have to run the install again and choose the repair option to get the addin to show up in Outlook.   Does anybody have an idea what is going on here   Thanks Ignus ...Show All

• Visual Studio AsyncRendering in ReportViewer

  I have a report that has 11 pages, When i have the Asyncrendering option to true, I can navigate to the all the pages. But when I set the Asyncrendering option to false, the first page displays but on clicking the next pages I get a page navigation error. I wanted to know what this option really does. When Asyncrendering option is true, I believe it has to get the whole report - all the pages, but when asyncrendering is false, how do you tell the report viewer to get the next page. I saw that there are page navigation events on the report viewer but don't know how to code for them. Any help/suggestion is appreciated. Thanks Hi Sir, ...Show All

• SQL Server No buffer space available

  First this isn't really related to integration services, but it seemed the best place to ask. I have already done some research online, but I'm having a hard time nailing down my problem.  It seems that this usually relates to TCP stack overflow, usually tied to JDBC, based on my research.  However... I am inserting several tables in sequence from a linked server (connecting to a PostgreSQL database) and I can run the process without a problem usually.  Then I got the following error message repeated for each table yesterday afternoon. OLE DB provider "MSDASQL" for linked server "[LinkedServerName]" returned message " ...Show All

• .NET Development What .Net Framework to use???

  Hi, I'm building a windows forms application to be downloaded from the Internet and allow the users to connect to a server and exchange information using Sockets. My dilemma is what version of .Net to use. I wanted to use 2.0 but I'm afraid that users will quit the download if they have to get a 20MB .Net install file. I know I can have an application stub and do all the downloading after user runs setup.exe but still it takes about 12min in a DSL to download the framework. At the other hand I don't want to stay back with .Net 1.1, which has a greater penetration in desktops; Visual Studio 2005 and .Net 2.0 have some great features. ...Show All
