• Software Development for Windows Vista How to pass parameter in ManualWorkflowSchedulerService

• Visual C++ Program runs slower when compiled with Visual Studio 2005 (in Release with optimization)

  Hey, I have a performance problem with the new Visual Studio 2005. My code (which is a genetic algorithm) is 3 times slower when compiled under Visual Studio 2005 compared to when I was compiling it under Visual Studio 2003. With Visual Studio 2003, it used to run in 3.0639 seconds, and now it runs in 9.0031 seconds. I run both code in Release. I tried every optimization option, and adding the /D_SECURE_SCL=0 compiler command to the project options with only minor differences. Is there any other way to get back to the speed Visual Studio 2003 It is a bit absurd to upgrade to a new compiler and get lesser performances. Thanks a lot!!!

• Visual Studio Team System TFS MSSCCI asking for Team Foundation Login Information?

  Why does the TFS MSSCCI provider have a prompt for Team Foundation Login information I am using VS.NET 2003 with the TFS MSSCCI provider and when it comes up the first time on a PC it asks for the login information. Shouldn't it be using the credentials of the logged-in user I usually just entered my password without understanding why, but now that we use client certificates instead of username/password I need to know how to get around this issue. It also seems that it stored this information somewhere because if you are able to successfully authenticate, it won't ask you again. Any help on this issue would be most appreciated. With Msscci you can be authenticated as other identity than the logged-in user. This is the value that yo ...Show All

• SQL Server replication "Invalid syntax error": Table has computed primary key

• Windows Forms how to avoid multiple task icons in the taskbar.

  Hi, I have multiple forms in my application. When I open a form from another form, two form icons are displayed on the Taskbar.But I want only form2 icon to displayed and form1 icon should not be seen.However Form1 will be in inactive state. I should not hide Form1 and at the same time only present form icon should be displayed in the Taskbar. In Visual Basic 6.0 we do this by: Form2.Show 1 Now I want a similar thing in VS2005 C# also. Thanks in advance, sukanya. Hi Sukanya, You can control wether a taskbar icon appears by setting or resetting a forms "ShowInTaskbar" property. You have to do it manually, there is no mechanism for having it done automatically. Tonn ...Show All

• Visual Basic Threading in VB.NET is complex--any alternatives?

  [Background and rant first; question below.] In VB5, I wrote a simulation model with 2-D animation on the form. I could start, pause, continue, and stop the simulation. While the simulation subroutine was running, the form controls still processed user's clicks, and the simulation could query the controls' state and pause or stop as requested. It was all in one thread; I didn't even know what a "thread" was. Now, I'm writing in VB.NET another simulation with 2-D animation. I want a "control center" form with start, pause, continue, and stop buttons, a small progress bar form, and an animation form. These have to communicate using shared data and event firing. I am spending a ridiculous amount of time learning a ...Show All

• Visual Studio Team System Ability to incorporate relational data within TFS fields?

  I would like to add role information to a customised work item. When a user is chosen from a dropdown, I would like the role dropdown to default to the chosen user's role. Currently both users and roles are defined in Global Lists, but I wondered if there was anyway that I could move to a relational model. Can this be done Yes, moving the data to a database and doing databinding is what I'd like to do. You say that SP1 will allow the creation of custom controls - is there a URL that I can follow to get some more information on this Installing a custom control on all the relevant users' machines would would be a viable option for my work situation. ...Show All

• Visual Studio Team System TSQL Debugger is not working after installing "VSTS - Database professionals"

  Hi, After I have installed VSTS - Database professionals CTP5 I have found that TSQL debugger is not working any more. When I put breakpoint into the stored procedure and do "Step into Stored Procedure" the break point became disabled and the message is "The breakpoint will not currently be hit. Unable to bind SQL breakpoint at this time. Object containing the breakpoint not loaded." I'm absolutely sure that this was working normally before the installation of the CTP5. I'm guessing that something was done to the security settings by the installation package. I hope it is fixable.
