Find Absolute Coordinates In Pixels Of A Certain Cell?
Feb 12, 2012
How can I find the absolute coordinates in pixels of a certain cell?I am developing an Office 2010 addon (the Ribbon UI) and I add a new button to a new menu in the Ribbon and when the button is pressed, I want to get the screen position of that cell. The problem is that [code]only give the position relative to the A1 corner of the spreadsheet, while I want the position relative to 0,0 of the screen.I found this: How to get screen X and Y of an Excel 2003 cell in C# but it's for Office 2003,

is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?

How do I find the color of a pixel at a certain coordinate of an image in a picturebox?
I found a bunch of tutorials but they are irrelevant and do not work for vb 2008 express.

How can I get the application's path in .NET in a console app?
I would like to find the absolute path from where my exe file is running.
i.e if i run my application/exe from c:my-appmyapp.exe then it should return c:my-app.
My target is to find my database location inside the db folder.

How do I get the screen coordinates of a DataGridViewCell? It seems that GetCellDisplayRectangle get the coords relative to the upper-left corner of the DGV & not the screen. I'm trying to display a small popup form next to a DGV cell that is clicked. I can get the actual cell object with Dim cell As DataGridViewCell = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex), but I need to get the coords of that cell to set the location of the popup form.

I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.

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.

I'm trying to find the colors of pixels using GetPixel(x,y) with bitmaps.
I understand how to use it and it works.
When I use .ToString I get the string version of the color.
Now when I use .ToArgb I get a negative number and the colors are backwards?
16777215 should be white and 0 should be black.
This is an example of some results:
-16273900 is showing close to black and -32567 is showing close to white.

I need to write a code to find identical adjacent pixels in a bitmap image. It should work as the 'magical wand' in Photoshop. My images are always black and white (white background with car parts drawed in black). Given the x,y coordinate for a single black pixel in the whole image, the code should find (and paint with another color, say red) all other black pixels that are linked to that one, and so on, until all linked black points will be painted in red.

All other parts will remain black. Does it make sense?At the end, there are two pictures (before and after) to help understanding what I need to do to the images.I tried a simple 8-pixel adjacent approach for every pixel (starting on initial coordinate) but it turns out into a very stupid and endless looping algorhitm.

Imports System.Drawing
Imports System.Drawing.Drawing2D

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 wanted to create a module / tool similar to MS word where user should be able to add controls, resize controls, drag and drop controls.Anyway, I have got lot of references on how to resize control, drag and drop add control etc...my main requirement is i need a way to add grid and should be able to add cells to it. When i resize the grid control, the cell height & width should get extended and compressed accordingly. Also i need to save position of the controls to a text file.Saving positon of other controls is easy but most importantly i need to save each cell position of the grid.

I know how to find the mouse coordinates of different controls and such. What I need is slightly unique.I'm needing to find the coordinates of a picture within a picture. So if I had a picture of a black box with a red x in it, I would need to find the red x inside of it.I already have the bitmaps of the images, so I only need to know how to find the coordinates of where the images lie inside one another.

On my VB excel macro, I am trying to create a code to search a key word on a specific row and to display the adjuscent 5 cells values in a text box. That keyword will be repeated here and there on that same row. But the adjuscent 5 cells value will be differ each time when the keyword matches.
For example: Row 20 has a word "We gave" (key word) in cell D20. I want a textbox to display the values of E20, F20, G20, H20, I20 in a text box. Then on cell M20, there will be another "We Gave". Then it should keep the value that it displayed in the text box earlier and to show the newer values of N20, O20, P20, Q20, R20.

I have been using this code to find the value of the cell in a datagrid view
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
MessageBox.Show(dgv.Item(0, eRow).Value)
This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
