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

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")

Develop a Company Logo application that allows users to draw shapes. The application should provide the user with RadioButtons to allow the selection of the next shape to be drawn. TextBoxes should be provided to allow the user to enter coordinates (X and Y coordinates) of the shape, the width and the height of the shapes. Users should also be able to change the shape�s colour.my question is how to allow the user to enter coordinates (X and Y coordinates) of the shape, the width and the height of the shapes and change the shape�s color from combo box. pro help

I have a problem related to a project work of field observations of points. So I have a text file (file.txt) of coordinates X and Y of vertexes (separated by a comma like below):
X, Y
12.2 , 13.1
15.4 , 19.3
13.6 , 12.5
(and so on to 15 lines of x's and y's)
I need a program which can read this text.txt file with the given coordinates and store them as 2 generic lists using Loop and Split function and also the program should display the data read from text.txt file into a multiline text box. Next the program has to use the 2 lists to be passed to a function that first calculates the average values for the coordinates X and Y, and then work out the areas of triangles by = 1/2 SUM [ (xb-xR)(ya-yR)-(yb-yR)(xa-xR) ] where x/y ''a'' is the current vertex and x/y ''b'' is the next vertex in the polygon. I presume the program has to loop around the whole polygon to vertices to summing up the areas of the triangles and at the end multiply by 1/2 and give the positive modulus or ABS() of the area.

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.

does anyone know how to connect points of a label? Let's say I have a label and start the label at point 0,0. Aterwards, the points jumps to 3,6 ... then to 6, 9 dynamically based on incrementing 3. How do I show for example, the path it takes to let users know where they are? for example, 0,0 --> 0,3 --> 3,6 --> 6,9 --> etc. I've tried with drawline but unfortunately, this leaves my lable in a mess.

At the minute I can display the mouse position using Cusor.Position.ToString() but my screen resolution is widescreem - 1360:768. What about about someone with a standard 1024:768? If I use my application on other computers, it won't work because it deeply depends on mouse co-ordinates
I am aware of a world coordinate system (or something) that will work on all screen resolutions. To use this (which I will need to) I will need to change all of my coordinates in the code? So I'll need to display it in a text box like I did with Cusor.Position.ToString() but what code can I use to get the world coordinate?
There is something like PoibntToScreen and PointToClient but what do these do exactly and how do I use them? I tried using
Code:
MouseCoordinates_tssl.Text = "Mouse Coordinates: " + "{X:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).X.ToString + "; Y:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).Y.ToString + ";}"
but much to my disappointment, it didn't work. What could I do that would work?

I am using the following to store the X Y cords
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
MyX = Me.Location.X
MyY = Me.Location.Y
My.Settings.Save()
End Sub
But the Me.Location.X or .Y are not detecting the forms position when I move it?

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.

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 "," ?

I'm writting a small program to send data to another application.Have not probs with that, my only problem now is to get the coordinates relative to the screen of that application so I don't need to move it, when I start the application, or to avoid probs if the customer moves that application on the screen.Currently this is my code to find if the other application is running or not, and if running then move it to the left upper corner of the screen.

Is there any way to get the mouse coordinates on a control behind an another control.
The exact scenario is, I have a picture box of size 1024*1024 and and an another picture box of size 256*256 over the bigger picture box (of size 1024*1024). Now, when I move my mouse over smaller picture box, I want the mouse coordinates with respect to the bigger picture box behind the smaller picture box on which the mouse is moved.

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.
