Adding A Point Overlayed Over A Specific Photo
Sep 8, 2009I've searched the forums for this, but I can't seem to find exactly what I am looking for. I have a form currently that allows me to open a photo in a picturebox. I would like to add functionality that would allow the user to click on a specific part of the photo and add a point overlaid on the photo. This point would be the graphical representation of comment that they will enter in a separate text box. I am stumped on how to even start to get this done.

View 1 RepliesInsert Row At A Specific Point In DatGridView Control?
Mar 29, 2010I have a DataGridView control which is NOT bound any underlying data table. When the user selects a row (multi select is not enabled), I want them to be able to click an "insert" button to insert a row into the table below the selected row.I can insert a row at a specific location with the code below, and it will insert a new row at the location specified. My problem, is that I need to get the currently selected row and add 1 to it. However, the insert method below accepts an integer, and I cannot figure out how to get the currently selected row as an integer. I can only get it as a Row collection, which does not help. Can someone tell me how to get the currently selected row as an integer?[code]

View 1 RepliesChanging The Color Or A Specific String In A Textbox?
Apr 29, 2009I have a project im working on and im trying to change the font color of a specific string basically how vb does while your coding. (eg if i type dim it turns blue).I want to do this with a textbox in a vb application to show a topic of interest. It needs to be dynamic so when a user types it only changes the color of the specified string. I have tried
If TextBox2.Text.Contains("dim") Then
TextBox2.ForeColor = Color.Red
End If
but this changes all the text in the textbox to the color.
Example Diffrent Color For A Specific Value In A Datagridviewcombobox Column

To show the Displaymember we want to see I've also added the toString property that should shadow the toString of the object.[code]

VS 2008 Scan The Screen For A Specific Color?
Aug 20, 2009A way to scan to whole screen, and find a specific color on it - and after that move the mouse over the color.
This is what i would like the process like, so you guys can have a better idea:
1. A timer that scans the whole screen after a specific color every 5 seconds.
2. When the color appear on the screen, it'll move the mouse to the x, y.
3. After that I'll run some code (i'll hopefully find out of that myself)
I actually don't care how the color should be found. If it's a RGB it will be 255, 209, 102 it should look after. Or maybe it could scan the screen after a matching bitmap. And it's not just 1 pixel I want to find the color of, it's the whole screen I'll like to have scanned for the color, and if the color is found - the program should react.

For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.
