• Windows Forms Speeding up background image

  I am using c# & .NET to try to make my version of the classic snake game, where the snake eats things and gets longer. I am using the GDI to do everything. My problem is that when I added a background image for a textured background instead of just using a solid background color, it slowed everything down a lot. I have tried putting the image in this.BackgroundImage, I have tried embedding the image instead of loading the file (which didn't help), and I have tried drawing the image from the OnPaint handler (which sped it up a little, but not nearly enough). I have also tried using bmp files instead of compressed jpg's and that didn't make any difference. Is there any way to have a background image without slowing things down this much, ...Show All

• Visual Basic Tableadapter.update with auto-increment on SQL column problem

  Hello, I'm using databound textboxes to display data from a database on VB.net 2005. I have an "add new" button, which does this: BindingSource.AddNew() - and then once the user has entered the details, they click a button that updates the database: Try Me.ChildrenBindingSource.EndEdit() Me.ChildrenTableAdapter.Update(Me.Main_databaseDataSet.Children) Catch ex As Exception MsgBox("Update failed") End Try I have a primary key field on the database (I'm using MS SQL express) called "ID". I've tested all the above with the user entering their own ID, and all works fine, but I want this to be auto-incremented instead. So, I set my MS SQL "ID" column up with these pr ...Show All

• Visual Studio 2008 (Pre-release) UDP channel example crash

  Hi, I am running UDP custom channel example from SDK on June CTP (SDK and WCF versions do match). I get an null reference exception in InitializeURI method. The sample has two parts - code configuration and config file configuration. The crash occurs in first part (code configuration), when using SampleProfileUdpBinding. Anybody got it running Thanks Alex This is a bug in the June CTP SDK. The relevant code in UdpChannelListener should look like: Uri baseAddress = context.ListenUriBaseAddress; if (baseAddress == null) { if (context.ListenUriMode == ListenUriMode.Unique) { UriBuilder uriBuilder = new UriBuilder(this.Scheme, Dns.GetHostEntry(string.Empty).HostName); uriBuilder ...Show All

• Visual C# Interfaces and Abstract Classes

  Hi, I am hoping someone can explain this to me. Lets say I have an abstract class called Employee, from Employee, the following classes are inherited, Manager and Cleaner Can someone explain to me how to incorporate an Interface for this scenario so my application can tell which type of object "Manager or Cleaner" its dealing with Thanks RizwanSharp, I understand what you are saying but there is no way for me to know what kind of employee logged in before going into the database. Since the employee class is an abstract class I cant say Employee emp= new Employee() emp.authenticate(); if(emp.PositionID==1) //Manager { frmManager managerForm= new frmManager(); managerForm.Show(); } thats why I ...Show All

• Windows Forms Results from a worker thread into main thread?

  I have a C# dll which provides an event of SqlDependency Notification messages to clients via a delegate. The event fires ok and I get the expected data. The problem lies when I try to get the resulting dataset into a DataGridView without having to implement a manual refresh via button click. I'd like for this to automatically update upon change. I'm thinking the reason is because the data is coming from a worker thread within the SqlDependency class and I have to create some means of marshalling it into the main (gui) thread. Below is my first whack at the event handler but for some reason it does not work. That is I still have to mash a refresh button. Can anyone offer a suggestion void ExcepNotification_NewExceptionNotification(Data ...Show All

• Visual Basic Can't get Microsoft Regular Expression to work

  I have urls that may start with "http" or "https" where I want to get the last parts of the url. For example, in "http://pear.nadd.tron.com/engg/resources/dwglogs/sum/sumpdf/joesl.pdf", I want to get just "resources/dwglogs/sum/sumpdf/joesl.pdf". The first part is always one of two ways depending on whether the url has "http" or "https", and that is always followed by "://pear.nadd.tron.com/engg/". I want everything after that. I can't see a way to extract the last part of the url I want with SubString and/or IndexOf, so I tried using regular expressions. However, I can't get the example in the Microsoft help file to work (http://msdn.microsoft.com/library/default.asp ...Show All

• Microsoft ISV Community Center Forums Cell Equal To EXACT Value

  Hi all, prob a very simple question for you guys. How do you check if a cell equals an exact value of "Product" I am currently using: Cells(i, 1).Text = "PRODUCT" though this is also picking up any cell which contains the word Product, such as cells which contain the word Production. So how do you check for an exact value Your problem statement is inconsistent. I put these values into A1:A3 of a new sheet: product Product Production I ran the following from the Immediate Window: For i=1 to 3 : Debug.Print Cells(i, 1).Address, Cells(i,1).Text, Cells(i,1).Text = "Product" : Next with the following result: $A$1 product False $A$2 Product True $A ...Show All

• SQL Server Oracle and unicode

  Since the .net oracle providers are the only ones that work in x64 it is extremely annoying that it insists on mapping ALL varchar columns in oracle to wstring. Is there a way to fix this The oledb providers don't have this problem but I don't like being forced to use the 32 bit runtime as a workaround.
