Translate MouseEventArg.Location X,y Pixel Coordinates To Custom Grid Coordinates?

Nov 29, 2010

I want to translate MouseArgEvent.Location (x,y) coordinates into my custom graph coordinates. Mouse Y coordinates increase from top to bottom while my grid's y value increase from bottom to top. Given my following code, I would need to create 21,500 separate conditional expression for 100(y) x 215(x) possible coordinate locations for my grid.

Sub OnMouseMove(ByVal e As System.Windows.Forms.MouseEventArgs)
If e.X > 48 AndAlso e.X < 50 AndAlso e.Y > 397 AndAlso e.Y < 399 Then
MessageBox.Show("about 0,0")

Set Coordinates For Each Beam At Intervals Of 610 Then Write That Coordinates System To A Text Based *.SCR File

Dec 2, 2010

I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

Getting Cell Values Into Variables In DataGridView Based On Grid Coordinates?

Mar 20, 2011

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...

Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....

Presently, that will only display the data in column 0, row 0 in those labels...

Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

For example, if I have 3 labels on a form and I want label2 and label3 to display the x and y of label1 relative to the screens top and left corner.

Coordinates - Control Relative To The FORM - "Control.Location DUH!!"

Nov 13, 2008

I have a control on a form - I need to know the coordinates of that control relative to the FORM.

Now before I get six replies saying, "Control.Location DUH!!" that only works when the control's parent IS the form. What if the control is nested inside one or more container controls?

Could I write a routine that crawls up all parent containers until I reach the form calculating each offset as I go? Sure! But this extremely crude operation seems clunky to me - What I'm looking for is something a little cleaner.

So far the closest I've been able to come is this:
Dim ClientPoint As Point = Ctrl.PointToScreen(Ctrl.Location)
Dim LocationLeft As Integer = (ClientPoint.X - Ctrl.ParentForm.Left) - Ctrl.Left
Dim LocationTop As Integer = (ClientPoint.Y - Ctrl.ParentForm.Top) - Ctrl.Top

The problem with the above code is: It does NOT take the Form's border or Titlebar into consideration... so this calculated location would be off slightly depending on what kind of border the form has.

IDE :: Getting The Screen Coordinates?

Apr 13, 2010

it is designed to be able to interact with foreground windows and display certain bits of information as each foreground window is displayed. The foreground window will most of the time NOT be a windows form so this makes things that bit more trickier for me. The program below doesn't produce any errors but the problem arises when I try and get the X, Y coordinates of the cursor, at the moment when ever the cursor is moved around I get a very long number as the X and nothing returned for my Y. I find I can set the X,Y coordinates to anywhere on the screen, can also get the foreground forms title,it's RECT coordinates but need to get the cursor info correctly.

Option Explicit On
Imports System.Text
Imports System.Runtime.InteropServices

Derive Coordinates From An Array Value?

Apr 30, 2012

I've got an array that contains the following:

a;b;c;d

but it can also be that this array contains this:

a;b;c;d;(0,0,1000,1000)#(1000,1000,2000,0)

So first I do a split on ";"

If Ubound(array)= 4 then I now the second case with coordinates is valid... in this case 2 sets of 4 coordinates

How do I derive them from array(4) as xstart0,ystart0,xend0,yend0 and xstart1,ystart1,xend1,yend1 ???

Do I need to do another split on "#" first and then on the "," ?

Printing Coordinates For RTL Using The PrintDocument?

I'm sending a rtl text "Arabic" to a receipt printer. My problem is in selecting left and top coordinates for each line. If the paper width changes the whole procedure needs to be written for that specific width, because I'm measuring form the left edge. Is there a way in the printDocument object that flips the starting point from left to right?

p.s. the format string in the args.Graphics.DrawString() only select the direction of the printed string in case it has some numbers and symbols but it doesn't start the string from the right edge of the page.
