Unable To Use A Linq-to-sql Statement And Getting A Left Outer Join To Work?

View 2 RepliesUse The Left() Function In VB 2010?
Oct 17, 2010I have a very small VS 2010 app that basically reads the records of a text file, adds some additional information to the end of the record read, and writes the new record to a new text file.The issue Im having is with the Left() function.I need to take all chars left of position 10 of a text box and add it to the end of the new record before I write it. When I use the Left() the "Error List shows an error related to this function.The error says:Public Property Left As Integer has no parameters and its return type cant be indexed.It gives two solutions: 1) Generate Method Stub Left in Project1.Form1 and 2) Generate Property Stub Left in Project1.Form1 When I select solution
1) that creates a warning indicating: Function Left conflicts with property Left in the base class Control and should be declared Shadows. When I select solution
2) that creates a warning indicating: Property Left shadows an overloadable member declared in the base class 'Control. If you want to overload the base method, this method must be declared 'Overloads.
Here is the code:

Mar 15, 2010Since the string class does not have a Left method, how would you do this in VB.Net. I could use String.SubString(0, x), but the problem with this method is that it throws an exception if the String is not at least x characters long. Should I use the Microsoft.VisualBasic.Left function instead?

C# - .Net Equivalent Of The Old Vb Left(string, Length) Function?
May 9, 2009As a non .net programmer I'm looking for the .net equivalent of the old vb function left(string, length). It was lazy in that it worked for any length string. As expected, left("foobar", 3) = "foo" while, most helpfully, left("f", 3) = "f".
In .net string.Substring(index, length) throws exceptions for everything out of range. In Java I always had the Apache-Commons lang.StringUtils handy. In Google I don't get very far searching for string functions.
Edit:@Noldorin - My first encounter, although it took me several seconds to do the same in c#:
[Code]...
Note the static class and method as well as the this keyword. Yes, they are as simple to invoke as "foobar".Left(3). See also c# extensions on msdn.

String.Format Function Return Only Left 10 Characters?
May 2, 2011For years I never had trouble with this String. Format function until today when I got a value longer than 0 characters and the function returned all the characters in the string instead of just ten. Now sometimes I get less than ten characters so I can't use the substring with out getting an error. I can try the left function but I was hoping there was a solution with the Format function.
View 6 RepliesVS 2010 - Keybd_event Function, How To Send Arrow Strokes Left, Right, Down
Mar 16, 2012I'm trying to develop macros for games. I'm currently coding with vb 2010 and I'm using the keybd_event API. It works great, I've done many working macros but I cannot find a way to send arrow strokes using this API. (Left, Right, Up, Down) I don't want to use the numpad. Here is what I've found: [Code] For some reason, nothing happens, no keystroke seems to have been sent. When I use any other ascii decimal from the ascii table, it does work but not for the arrow strokes.
View 2 RepliesForm.Left And Form.Top To A Different Screen Don't Work?
Aug 24, 2009I've run into a little problem recently. My computer has two screens sitting side-by-side.
Here are the dimensions for my first screen: {X = 0 Y = 0 Width = 1280 Height = 1024}
Here are the dimensions for my second screen: {X = 1280 Y = 0 Width = 1280 Height = 1024}
My form saves its position on exit into the Registry. Whenever I start my application, I set its opacity to 0 in the constructor and it goes to my first screen. While its opacity is at 0, I then move it to its previous location (1280, 0) like this:
thisForm.Left = X
thisForm.Top = Y
Where X = 1028 and Y = 0.
I place a breakpoint directly in front of those assignments and when I hover over thisForm.Left, it = -4. Whenever I hover over thisForm.Top, it = -4.
Sure enough, when my form comes up, it's in my first screen.
For those interested, I've now worked around it, by doing some additional testing. What caused it: My Window State was Maximized. Solution: If before I set these positions, I change my Window State to Normal, the form moves. I can then maximize it while it's on the second screen and it remains there. why I can't move my form while it's maximized? It's more for curiosity than to find a solution, since the work-around is actually working quite well.

VB Can't Get The Right Function To Work With Strings
Jun 20, 2012Basically, I'm trying to do some string manipulation to edit directories. I found some code to try and edit the directories, but when I use it it doesn't recognise 'right' as being a function and only recognises it as a right property, thus producing an error.
I was wondering if there's something I haven't imported or if perhaps 'right' is an obsolete function that was used in VB6 but replaced with something. The code I have is as follows:
