• Windows Forms Data Sources Window Customize

  Hi, We (almost) strictly use 3rd party UI controls in our UI layer. So, I've customized my Data Sources window to map our 3rd party controls (Infragistics) to the available data types (via Tools->Options->Windows Form Designer->Data UI Customization). All of that is working great, with one exception; when I drag a data object's property to my Form from the Data Sources window it'll place a "canned" System.Windows.Forms.Label control next to my 3rd party UI control. Is there any way that I can specify to use (map) a 3rd party label control instead of the canned label control for this label describing/naming the property that I dropped onto my form Thanks in advance, Skip V. ...Show All

• SQL Server [OTP] Multi User Application Database Transaction Stability

  I am currently developing a multi user VB.NET 2005 application and this is my first time to involve in multi user application. Anyway, i know that multi-user application is not as easy as standalone application. I need to take care of the database stability for each and every user. My concern is may i know how to build up this stability for each and every transaction in terms of Data insert and update This database resides on server and the user is able to access the data through the client application. INSERT The primary key is generated by application when the user enters into the data insert screen and it is done by counting the total amount of records in database. If two users perform insert at the same time, may i know how t ...Show All

• Visual Basic Need To Create Search Bar For Database

  Greetings, I am completely and utterly amazed at the lack of information on how to create or employ a search bar. This is the one simple attribute that has made the internet what it is today. Nearly every program I have ever used has a search bar which, when data is entered into the textbox and the search button is clicked, it returns matching criteria. However, I have searched (Imagine That) Google, Yahoo,LearnVisualStudio.net, MSDN, and Help for three days on how to create such a simple procedure and have found nothing. What I need to do: I am creating a database where I have all my Employees Information which includes columns: [Employee Number], [Emloyee First Name], [Employee Last Name], etc.... I have created the database and ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. no query - big mistake

  Hi, Paul Bleisch said about support for device queries: "They are not there today. What are the scenarios where you are using device queries (i.e. which queries) We've had much internal debate about this (in regards to the general lack of support for them and what the API should look like if we did it)." My question is: Whether there will be a support for device queries and when the XNA team will spend the patch to XNA which is removing this big mistake Cheers, query. Well someone else also mentioned this but I noticed that nobody has entered a bug/suggestion into connect.

• Visual Basic VB computing wrong value during execution

  I am receiving the wrong result when I perform the following computation using VB.NET 2005. MM = CDbl (LoCursr - 1) / CDbl (HiCursr) LoCursr and HiCursr are both dimensioned as Integers and have values of 85 and 87 and are passed into this subroutine as ByRef values. MM is a local variable declared as a double. If I execute this statement in the immediate window, I get the correct result of 0.96551724137931039 However, when this statement executes normally, I receive a result of 0.96551722288131714 which I also get if I execute Cdbl(Csng(84/87)) in the immediate Window. I've tried storing the LowCursr and HiCursor values in Doubles prior to doing the computation, but that did not correct the problem. Is there a se ...Show All

• Visual C# Multidimensional Arrays

  Ok, my book really sucks I think. After struggling with an example in the book, I looked in the MSDN and searched these forums. I believe my book is wrong when it shows: int[,] student = new in[4][3]; I tried doing it that way but it errors. int[,] student = new int[5,4]; gives me no error and works. I am going to go with that. Unless someone can tell me that int[,] student = new in[4][3]; is indeed a correct format or what kind of a typing error it could be... The following also seems to be in the wrong format: int[][] x = { { 2, 3 }, { 4, 5 }, { 6, 7 } }; I don't think you can do it that way... Ok, but I still get the error array initializers can only be used in a variable or field initializer, try usi ...Show All

• Visual Studio Express Editions Cannot register filter with win98se
