• Visual Basic VS 2005 IDE Unresponsive

  We had originally installed Beta 2 of the product which ran better than expected. After using the tool from MS to uninstall the beta software we then installed VS2005 Final which we downloaded through our msdn subscription. The IDE becomes just about unusable. Not only that but it pretty much renders the computer useless while it eats up CPU cycles. This occurs during the following conditions: 1.) We make a small change in code and the editor hangs, the hour glass pops up and the cpu usage for the devenv.exe process is usually at 99%. The icon at the top of the VS IDE switches to the default exe icon. This unresponsive behavior usually ...Show All

• .NET Development Discrepancy between how Uri class parses URL and the way Internet Explroer does it?

  Here's a Google Desktop URL: " http://127.0.0.1:4664/&s=8lD6KsMwZ1Zd3ZWWqfZb327gN6g&q =". Internet Explorer properly treats everything after the last '/' as a query string (even though starting query string with '&' instead of ' ' is odd). To prove this is the case just look at the page sorce and see google desktop logo <img> has relative src=hp_logo.gif, which corresponds to http://127.0.0.1:4664/hp_logo.gif URL (check image properies in the browser). Now load the same http://127.0.0.1:4664/&s=8lD6KsMwZ1Zd3ZWWqfZb327gN6g&q = URL into the .NET Framework 1.1 URI class. Observe Query property = "" ...Show All

• Smart Device Development Controlling a device power state on XP

  Hi, I have no previous experience in device related development. My question: is it possible to control a device power state (more specifically, turn it on and off) on XP I found SetPowerState, which is only available for Windows CE, and various WMI "SetPowerState" methods that aren't implemented. If it's possible, then how Thanks, Osnat Yes it is possible. You can do it by writing a command line program for the device in which you can pass arguments to the .exe. Then using www.OpenNetCf.org 's Desktop.Communication library you can call the command line application .exe (from you desktop maching) using Rapi.C ...Show All

• .NET Development About strong naming

  I am a beginner in strong naming. I have read that strong naming is done in command mode when the assemblies are ready to deploy.  However, I have an application which involves over 80 assemblies.  What are the proper steps to do strong naming for the application   What I will going to do is: 1. In VS.NET, switch to 'Release' mode and compile. 2. Use command window in VS.NET, do strong naming one be one. Am I right   If I need to recompile the solution frequently, should I repeat the whole procedure   That seem very troublesome... Thanks Hi Kennon, Thats correct. If you strong name an assembl ...Show All

• Visual Basic VB 2005 Compiler Optimization Discussion

    There's been something percolating in the back of my mind. I come from a computing environment that preceeded windows and the Intel Architecture and instruction set. n comparison to the instruction set that i'm used to, the Intell instruction set looks like a house wreck which may or may not be important to the discussion at hand. Everyone knows that moderators agree on everything and that in moderator space we just stand in love circles and sway back and forth. So when I was discussing a compiler one day, I said I really admired a language which had a seven pass compiler. "Nonsense", was the response, "two will do it." Wi ...Show All

• Visual C++ Using my MFC of Visual Studio 2003 Profissional on Express Edition

  Hi! I have bought the Visual Studio 2003 Professional and it brings with the MFC library. I would like to know if I can copy and use the mfc libs and headers in the Visual Studio 2005 Express   Thanks Victor Hi Victor, The answer is that we do not recommend you do this nor do we support this scenario. The VC 2005 source code has breaking changes and hence you will not be able to compile your code correctly using 2003 libs with the 2005 compiler. Hope this helps, Sarita Bafna Visual C++ Team ...Show All

• Visual Basic System.Runtime.InteropServices.COMException (0x800A03EC): Cannot access xls file

  Hello I am trying to retrieve the Worksheet name from an Excel spreadshet so I can load into a dataset for conversion to a .csv file. I am aware that Excel has that facility built in, but the users that use Excel are not familiar enough with Excel to use that feature, it is up to me to write an application that will do this for them. (Automate as much as possible, if you will.) Nevertheless, when I try to retrive the worksheet name, which is needed for objCmd, I receive the following error: System.Runtime.InteropServices.COMException (0x800A03EC): Cannot access 'IBM Legacy RISC Inventory.xls Some code snippets are included be ...Show All

• SQL Server Is the SP1 multilingual?

  Hi, Unlike the SQL Server 2005 SP1 download page, the SQL Server 2005 Express SP1 download page ( http://msdn.microsoft.com/vstudio/express/sql/download/ ) and the pages it references don't mention whether the download is english only or multilingual. Since there's no language selection possibility on these pages, I'm assuming it's multilingual. Am I right Thanks in advance. -- Patrick Philippot - Microsoft MVP MainSoft Consulting Services www.mainsoft.fr Hi, There is a dropdown to choose from: http://www.microsoft.com/downloads/details.aspx FamilyID=11350b1f-8f44-4db6-b542-4a4b869c2ff1&DisplayLang=en HTH, Jens Suessmeye ...Show All
