• Visual Studio Express Editions Visual Basic windows forms

  Hey, I've only started using Visual Basic tonight, and I've never touched any previous form of VB and/or Visual Studio. So this is probably the newbie-ist question you've seen for a few years if not ever. Anyway, I've got a task set out whereby I must create a testing program as such, with multiple choices. I've created a form for every question, along with a welcome form and a grade form. My question is simply, how do you link the forms, so that a user can click the button labelled "Continue1" and it opens up form2, within the same space and so on and so forth. Any help would be more than gratefully received. Thanks! on your form load, instead of "Me.Score" - that should ...Show All

• Visual Studio Express Editions Windows Position problems

  How can i get this to work, i wanted to make my window to save its position on screen everytime i move it, and then on load recall that and place the window where it used to be. Private Sub Form1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load Me .Location.X = My .Settings.PositionX Me .Location.Y = My .Settings.PositionX End Sub Visual Studio already provides the functionality you need to save keep track of your form's property settings. Instead of coding the Location property for yourself, you can bind it to your user configuration file so it will be automatically restored when the form is loaded. You can create such binding by following the next steps: 1. ...Show All

• Visual FoxPro System resolution

  Hi. How can I find out what the system resolution is, and how can I change it via FoxPro Thanks If the form is too short, the correct solution is to group your sets of controls in some logical way and place them in different pages on a PageFrame control. If the process of filling the form is formalized in a set of steps (e.g. step #2 must be done after step #1 and not jump to it directly), then you could use a wizard which is nothing more than a PageFrame with no page tabs showing and you control the page change programmatically. ...Show All

• Visual Studio Team System Schema Compare Problem #5

  I am comparing a Database to a Project. One table is showing up as being different. Here is what DBPro reports as the difference: In the Database: [DefaultPerformanceEmailText] [nvarchar] ( max ) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , In the Project: [DefaultPerformanceEmailText] [nvarchar] ( max ) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL CONSTRAINT [DF_HumanResourcesPolicy_DefaultPerformanceEmailText] DEFAULT ( '' ), When I click the 'Write Updates' button to synch my Project, DBPro says everything was successful but when I do a recompare, this same difference reappears.

  I am very confused with Counter Sets 'Threshold' values........ There are 3 categories under Counter Sets which are: Load Test, Controller, Agents and under each category there is a list of sub-category. Questions: Q1: Is there any way I can find out what is the average 'Threshold' values for each category for my website Q2: Is there any online resource or help available which I can use as a guideline to set 'Threshold' values Q3: Do I have to set all 'Threshold' values for all categories or I can leave some blank If I leave them blank than what is the default values Are they all set to 0 Q4: At the moment when I run a load test I get the following 'Threshold' errors even though I ...Show All

• Visual Studio VSS Strategy

  Hi, I would like to request for some advise. I need to maintain source code in the following environment: development testing production Is there any best practise/well defined strategy that I can learn from ie, should these 3 environments exist with 1 database within the VSS or as 3 separate databases Currently, I am using VSS 6.0 Thank you Danny. You should create them as branches from the start. That is, create just one project called $/Development. Branch it to $/Testing, then branch that to $/Production. When it's time to promote code, use the Merge Branches feature. If you can find Doug Neumann's presentation from TechEd 2005 (google is failing me at the moment), yo ...Show All

• Visual Studio Syntax error when using Online MSDN

  Hi, I have a problem with the Visual Studio 2005 help. Every page that loads i get a "line 1 syntax error" message box. It is DRIVING ME INSANE! I have tried to repair of the Document Explorer tool. I have looked for updates or KB articles and i can't find anything. I have tried turning off IE debugging but just the shape of the message box changes (and it doesn't ask me to debug), and the syntax error moves to line 2. A sample source for the page starts with XML so i thought that might be the cause but I am running the latest updates. Has anyone else had this problem Thanks in advance for any tips, Nathan Hi All, For your guide and info, I submitted a Bug Report through Microsoft Connect d ...Show All

• .NET Development Converting Access application to .NET

  I have an MS-Access application that needs to be converted to .NET. I know that there's an upsizing tool thru which I can convert Access DB to SQL Server 2005. Is there any tool to convert Access code to C# / VB.NET directly similar to converting VB6 code to VB.NET I believe there isn't as Access is different (VBA) than .NET. I could be wrong however but I am certain that you can't just "Convert" directly to C#/VB.NET - technology is different. What code is it you require to be converted from Access ...Show All

• Visual Basic VS 2005 - Windows Service Project and Setup Project questions

  My solution consists of a Windows Library (that creates a DLL), an EXE that is the Windows Service and a Setup project for deployment. The Windows Service references the DLL project. Everything is installed and deployed. 1. When I run the service, my code needs the current directory of my installed windows service application and library (c:\Program Files\Perf\PerfService in this case) but when I use the following code: path = My .Computer.FileSystem.CurrentDirectory It returns : C:\WINDOWS\SYSTEM32 How do I get where my DLL and EXE are installed 2. I am using a My.Settings config file (app.config) to store application settings for the DLL. How do I include this in my Setup project so that I can manually change settin ...Show All

• SQL Server Access Permissions on server scoped objects for login

  We are having problems with the response times from UPS WorldShip after switching from SQL Server 2000 to 2005. I think that the problem can be fixed from the database end by setting the permissions correctly for the user/role/schema that is being used by WorldShip to connect to the server but, I'm not sure how to do it. The Setup Client UPS WorldShip 8.0 running on XP Pro SP2 Connecting via Sql Native Client via SQL Server Login Connection is over a T1 via VPN Server - SQL Server Standard Edition on Windows Server 2003 2x3ghz Xeon processors w/ 4gb ram The user that is being used to connect runs under it's own schema and role and only needs access to two tables in a specific database on the server.
