• SQL Server maximum users logged in sql express

  we're planning to use sql express as our database server in our office. the database will consist of accounting, purchasing, marketing, sales, inventory, production and hrd tables. 80-100 users will use the system simultaneously in adding, editing, deleting, reports. i need some advice on the following: 1. maximum users that can log on to the database simultaneously 2. maximum size of the database tnx Truthfully, if you have 80 - 100 users hitting a database server that your company is obviously running its business off of and they can't afford to purchase about $10K worth of software to make sure they can function, they is something fundamentally wrong with the company. They are going to have several tim ...Show All

• SQL Server Installed SQLServer Express.....now what?

  Hi I've succesfully installed Visual C# and I've made a couple of example projects. I now want to try and create a database and see if I can make a C# application that talks to it. So I've installed SQL Server Express. I was hoping I could open it up and get started with creating tables etc. Instead, my Start menu shows: Microsoft SQL Server 2005 >>>Configuration Tools >>>>>>SQL Server Configuration Manager >>>>>>SQL Server Error and Usage Reporting >>>>>>SQL Server Surface Area Configuration Where do I go now Is there some configuring to do before I can start making tables and storing data Or, have I misunderstood what SQL Server is about Thank ...Show All

• Visual C++ Colorize inactive and _DEBUG

  Colorize inactive is a new feature in VS2005 (at least new to me) and it looks helpful. However, with my setup, it seems to not be able to keep track to whether _DEBUG is active (defined) or not. I expect that when I pick "Release" or "Debug" from the Solution Configuration different blocks of code bracketed by "#ifdef _DEBUG" will be grayed, but that does not seem to be the case. The graying does not change, and arbitrary (or so it seems) blocks of code are grayed. Is this a know problem, or am I doing something wrong Thanks, Marius Matioc I have just recompiled the project. I am in Debug mode and the #ifdef _DEBUG block is grayed. My solution has two project in it, ...Show All

• Windows Forms Tab Contol Help...

• .NET Development Can't step into web service in debugger

  I have a windows forms application that calls a c# dll which calls a web service (on my local web server). I wrote the code using VS.NET 2003 and had no trouble debugging. I have recently upgraded to VS.NET 2005 and can no longer step into the web service. When I set a breakpoint in the web service and start the app, I see an icon next to the breakpoint that says no symbols have been loaded for the document. I have added the following line to the webconfig file: < compilation debug = " true " > The configuration Manager shows all projects being built with debug on and when I look at the property pages for my web service, the asp.net debugger is checked. Does anyone know what I am doing wrong ...Show All

• Software Development for Windows Vista Problems creating a custom sequence activity.

  Hi to everyone! I’m trying to create a custom sequence activity which will be used in a state machine workflow. The intended use is to Drag&Drop the custom activity from the toolbox into an EventDrivenActivity (after the HandleExternalEvent). I tryed to add (by designer in VS.NET 2005) a SetStateActivity to my custom activity but this operation is not permitted so I tryed to add it programmatically (for example into custom activity constructor) but I receive an error saying that SetStateActivities are allowed only into StateMachine context and the solution does not compile. So I decided to add it using the ToolBoxItem CreateComponentsCore method but I receive an error. In my custom activity I expose a ...Show All

• Windows Forms Generic User Controls?

  After working on a windows forms project I realized many of my screens do very similar tasks on completely different types of data. I then decided to create a generics based user control to make reuse of all of this common work based on the Type of object the specific instance of the control is using. After I build my control I realized I no longer get any design-time support for my class. It doesn't even show up as a user control available in the tool bar. This makes sense, since an instance of a generic type needs the type defined in order for it to be rendered on the screen, however is there any way I can add this generic type to my windows form and specify its type and then be able to use the design-time support of modifying this co ...Show All

• Visual Basic How can I search a database on multiple criteria selected from listboxes?

  I am new to VB and I am finding it difficult to understand. I am using Visual Studio 2005. I want to search a database for several items, I am using the My Movie Collection template to practice with and I want to be able to search for actors, directors and release dates and see the movies that match. I want to use listboxes for the items to search on and populate them with the possible options from the database. Ideally I would like the results to be updated as I click on the options in the listboxes (no 'search' button). I want to be able to click on more than one item in a listbox (e.g. several dates) and I want to be able to deselect items that I previously clicked on. I have found examples of searching for one thing in a datab ...Show All

• Silverlight (formerly WPF/E) Multiple Storyboards

  I'm trying to create a simple rectangle which has a MouseEnter and MouseLeave event. These events trigger a corresponding storyboard. The first time I roll onto it the MouseEnter storyboard plays fine. When I roll out it runs the other storyboard fine too. But after that it never triggers the enter storyboard again.

• Game Technologies: DirectX, XNA, XACT, etc. Array of ID3DXMesh causes crash on draw with more than 2 elements

  Hi, Bit of an odd one - I think the solution is probably quite simple but I can't see it so maybe need a few more pairs of eyes please! I've got an array of ID3DXMeshes, and for each one I do D3DXCreateMeshFVF, then fill the vertex and indexbuffers. I then go thru the array and draw them. If I have just one element in the array, all is well. It gets drawn and it's released ok on exit. If I have 2 elements, it gets drawn ok but crashes when I try and release element[0]. If I have more than 2, it just crashes when it tries to draw the first one. I've been looking at this for ages now and am going a bit mad! Any help would be great. Below is the method that creates the meshes, the method that draws them, and the code where they are dec ...Show All
