VS 2010 - Keybd_event Function, How To Send Arrow Strokes Left, Right, Down
Mar 16, 2012
I'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.
How to send keystrokes to an application that does not have focus and is not selected. i have read about sendmessage, but am not sure how to use it or anything, not even sure if its what i need.
i dont need to send anything but normal character keystrokes
I am trying to use m.WParam to separate the event raised by left arrow key "<-" and right arrow key "->", but somehow m.WParam always = 0. How can i separate the event raised when the user press left or right arrow key?
I 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:
Public Class frmProcessFile Private Sub cmdProcessFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
I'd like to create a function in my application in Visual basic 2010 that would:Simulate a left-mouse button click+hold and drag with a timer tick eventSet a new XY coordinates for the mouse to drag the item to a new locationRemove the left-mouse button click+hold command
When I set rowheadersvisible to true and run the program, the little arrow appears on the left of the datagridview and a cell is highlighted. (Accessible role is none.)
I am making a little application to provide a simple GUI for editing controls for some old games that use INI files to store their config.I have just come across the following ini file key but I can't see how it is storing the controls. It is meant to be for an NES pad, which has 8 buttons - Up, Down, Left, Right, Start, Select, A, B.
I have a loop that takes text from a richtexbox, and pasts it into a field on a html web form within a webbrowser control.When i run my code, it goes to where it copy/pastes the text, however it keeps doing this over and over and over and over again, it wont just copy and paste 1 time, and stop.[code]
I want to send a left mouse click to a DataGrid. I've tried the below code with SendMessage and PostMessage to no avail.
Private Declare Auto Function PostMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal msg As Integer, ByVal wParam As Integer, ByVal lParam As Int32) As Int32 Private Const BM_CLICK = &HF5
I'm trying to format a string with the left and right fxn but am getting an error "Public read only property () as integer has no parameters and it's return type cannot be indexed"[code]...
i m using datetimepicker to choose date..i m extracting date from sql database...but i need to send only the date part not the time part.i m not able to do left funtion...here's my code...
cmd = New SqlCommand("select * from employee_log where log_datetime between '" + left(DateTimePicker1.Value,10) + "' And '" + left(DateTimePicker2.Value,10) + "'", cn)
the syntax with the left is incorrect...how do i do it...?
I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should. This is the code to send the string and my attempt at making it replace the () in the module
Module TextReplacement Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal vKey As Int32) As Short Dim counter As Integer Dim sData() As String

The error I get when i try send "Test :)" is: ArgumentExcveption was unhandled "SendKeys string 'Test :)' is not valid"
I expected the "Left" function in the code below to return the letter "A" but it returns nothing? Also, as a further test, Left(CP, 3) returns nothing?
Since 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?
I am trying to do string manipulation of an OpenID in my codebehind. For example, if the user enters " url...I want to do the following:
1. Remove the http:// or https:// if it exists
2. Remove the "/" at the end of the OpenID if it exists
So that all would be returned is url...I have used the Right, Mid and Left functions before with a string that contained spaces but I'm not sure how to accomplish what I'm trying to do here.
As 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.
For 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.
The form is a dialog, with KeyPreview = True and AcceptButton = (none)Handling Me.KeyDown, and Me.KeyPress do not trigger when I press either the Up, Down, or Enter buttons. Me.KeyUp will fire on up and down, but not enter.I put a breakpoint on the procedure declaration and the first line of the procedure (the Me.KeyPress and Me.KeyDown event handler procedures), and they never fire.
I know there is a way to remove it for the system, but I don't want to remove the little arrow from the desktop icons, I only want to remove it in my application window I am making. Adding the registry hack removes it from my app as well as the desktop, yet I want to keep those on the desktop. Is there something I can add in my app that will allow me to remove them in my application only? I am showing the icons in a lsitview
there is this picture on the form How would you make arrow keys move the object around the screen?Also how would you make buttons correspond to arrow keys?
I've got a simple textbox and as the user enters text in the textbox I display a label below with matching words (to what they are typing). When they click the DOWN or UP arrow I highlight one of the words below in the label.
