• .NET Development Connection object in a multithreading context

  Hi! Do i need a unic connection per thread or can i use a global connection for al DataAdapters That's, i have a multithreading app, each thread connect to the BD and get some rows and i don't know if i must create a new connection per thread or not. Regards. Thread Safety Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe. Open/Close and most other things you'll want to use aren't static so right off the bat you know you're going to have some synchronization issues. there is MARS which allows multiple commands to fire on one connection but that's a different matter. Take Paul's advice on this one and opt for pooling - it works ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problems with: Detecting if a user clicked on a 3D object

  I'm rather new at working in 3d at this level but not exactly new to C# and definitely not new to 3D models... but I usually work with a tool such as Blender, 3DS or Maya. I have my simple mesh object and it displays just fine. When I use the sample code as a guide, I find that I need to make my own Bounding Box... and I understand the process in theory but applying it to the code is giving me fits. **************** Issue1: Using a Bounding Box with the dimentions of triangleBB in the sample causes this: Nullable < float > result = pickRay . Intersects(triangleBB); // Returns NaN regardless of where clicked. That's my shorthand... pasted code with what it results in after the comment.... Question... so why ...Show All

• Visual Studio Express Editions To stop a Panel from Moving?

  I am programming a game where you control a "man" through a series of levels. The only problem is if you press the "Up" key while he is moving up, he will go off the screen. The man is as panel by the way. I fixed my code so that the "man" wouldn't move off the left of right side of the screen. However, when I use the following code, The man will still move off the top of the screen. How should I fix this I would appreciate the help. Dim up As Boolean = True If e.KeyCode = Keys.Up And up = True Then Man.Top = Man.Top - 7 If Man.Top <= 0 Then up = False Else : up = True 'This code is not all in the same place in my project. Wayne.

• Visual Studio Express Editions User Control does not respond to code in main form.

  Using VB 2005 Express. I found a project that plots a graph in a user control. The user control has a picture box and a label. The code for this project shows the code that goes in the user control. I set up a user control in a new project and added the code. After some tweaking I got it to compile. I then went to form1, dropped the control in from the toolbox, and tried to setup some code to use the user control. Code looks like this: ------------------------------------------------------------------------------ Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim gs As New UserControl1 gs.Xscale_Max = 15 gs.Yscale_Max = 15 gs.Xscale_units = 1 g ...Show All

• SQL Server Barcode font "shrinks" during PDF export

  Hi all, I'm using a free barcode font so i can create scannable tickets via reporting services 2k5. When I print the tickets, everything seems fine. But when i export to PDF though, it looks like the barcode font shrunk. All the lines are pulled together, making scanning impossible. Is there a certain setting or so that i can use to ensure the font's width  -Update- The weird thing is: when i export it inside visual studio, the barcode is shown as it is supposed to in the pdf ! Thanks in advance! Hi, I hate to say this, but we really did nothing to resolve the issue. Nor did I get any replies for this issue. We just restarted the SSRS server for some reason and after that we found ...Show All

• .NET Development Caught between a lock...and a hard place.

  Greetings .Net Gurus! I am writing a Windows service in C#. This service performs several related tasks. I have broken up the tasks into 2 different classes that I want to run in thier own threads. This is all fairly straightforward. The question I have revolves around how I update the text file that is logging various information for the service. I did a little research, and what I have come up with uses the Lock statement around the code that updates the text file. The object that I am using in the lock statement is declared as a public static object in a third class that is accessable by both the worker classes. If I have understood what I have read correctly using the object from the 3rd class will keep me from having any content ...Show All

• Windows Forms Tool Tip Disappearing

  I have a button for which I set a tooltip using the ToolTip class after finding out that there isn't a ToolTip property for button controls. Here is my code: ToolTip procDescriptor = new ToolTip (); procDescriptor.SetToolTip(newProcessButton, "text" ); procDescriptor.ToolTipTitle = processName; procDescriptor.Active = true ; procDescriptor.ShowAlways = true ; The tool tip works fine until the button is clicked or hovered over for more than 5 seconds. After either of those things, the tooltip never reappears. What's the deal -allen It's in my form class...but actually, I remedied the problem with a custom class that extends the ToolTip class in .net 2.0. It allows tool tips to reshow after " ...Show All
