• Visual Studio Express Editions Installing VB Express requires uninstalling VWD

  Ok, I'm stumped...  When I went to install VB Express it told me I had to uninstall VWD and SQL Server Express.  I did that and installed VB, but now when I try to reinstall VWD it tells me I have to uninstall VB. Can you not install both of them on the same machine at the same time Jay Alright.  Finally! I re-ran the VWD setup and had it repair and reinstall and now that seems to have solved all my problems.  I have them both up and running now. Thanks anyway, folks. Jay ...Show All

• Visual Studio Express Editions trouble creating a database from within VB Express 2005

  I'm new to databases and SQL and know only a little about VB. I have downloaded the latest versions of SQL express and VB express, and while I had a few problems getting SQL functioning, they do appear to be working. From within VB express, I can create a database item and add a couple of tables to it. However when I close them down and then try to reload them later (for example by trying to create a database diagram including the two tables), I get the error: "Table 'Channel' could not be loaded. Invalid column name 'is_active'." I have no idea what this means or where to start looking. I have tried looking through the SQL configu ...Show All

• Visual C++ preprocessor definition _VC80_UPGRADE=0x0710

  Hi, I noticed that this definition is applied to projects upgraded from VC7.1, but there seems not to be any reference to it on MSDN2. So can anyone tell me what exactly it does I.e. does it also alter any compiler defaults I also searched the source files in the VC install dir, and the only reference there is in VC\atlmfc\include\afxres.h. So Im interested it it has any effect other than in that source file. Thanks. If you look in \VC\VCProjectDefaults\UpgradeFrom*.vsprops you will find it there as well. It's not listed in any of the compiler binaries and its only use is related to a manifest ID so it seem ...Show All

• Visual C# HELP: Not working like it should

  I'm working through the "SAMS Teach Yourself C# in 24 hours" book using the free download Microsoft Visual C# 2005 Express Beta. I don't know if a lot's changed between the book being written in 2002 and the release of the beta but a few things don't seem to work exactly the same as in the book. Hence, some sections of code won't compile without giving errors. I've gone over the code meticulously and can confirm that I've entered it correctly. Is there a way to get the 2005 Express beta to behave like the older versions VS2002 was the first version of C#.  The second was called C#1.1, aka VS2003.  ...Show All

• Visual Studio Installing IE7 works but..

  Thought I'd start a new thread, since I'm using Visual C# Express, rather than full VS2005. Windows XP Pro SP2, Visual Studio 2003 Pro, SQL Server 2000 Developer Edition, Visual C# Express, Visual Web Developer Express, SQL Express 2005, MSDE. I also have Virtual Server 2005 SP1 beta installed. Problem just started this weekend. Whenever I click on any topic in the Index, Document Explorer crashes. I've tried Repair on Visual C# Express, Visual Web Developer Express and MSDN 2005 Express. Same problem. It was working fine last week, I'm not sure what's changed. I have previously had VS2005 beta2 installed, but I removed that by following the ...Show All

• .NET Development Using DPAPI in Winforms Applications

  It seems DPAPI can solve the problem of dealing with encryption keys, especially in the User Store configuration mode. I have two questions on DPAPI in relation to app.config data encryption: - If I understand correctly, when used in the UserStore mode, DPAPI will ensure that only the user that encrypted data through DPAPI can decrypt the data. Does that mean that in the case of using DPAPI for configuration settings (app.config), that we will have to run the DPAPI encryption for the configuration settings on each user machine separately during deployment Will we need a separate encrypted config setting data for each user  Does Mic ...Show All

• SQL Server Mapping Columns Automatically?

  New to SSIS... I created a new package with a source and destination and manually created the output column with data type, etc. Works. The issue is say the table has 200 columns to export.. I dont want to create these by hand. How can I just say export them all to csv format and not have to specify and map each and every column You could replace your existing source adapter with a new one. The default behaviour is to select all columns which by the sound of it is what you want. The new columns will automatically appear in the metadata of downstream components. -Jamie ...Show All
