Jun 5, 2009
I am fairly new to vb.net and the form includes 3 picture boxes in red which you can click and change their color to green, also each picture box have three text box associated with it and they are by default color dark gray. I want the system to check whether the picture boxes are clicked and if yes set the associated text box colours to white.
Here is the code I wrote:
Public Class Screen
Inherits Windows.Forms.Form
Dim T(1, 2) As TextBox
Dim S(2) As PictureBox
Dim x, i, j As Integer
[Code] .....

Let's say I have a PictureBox with an image of a house, for example, and I want to know if the user clicked on the roof, the door, the window, or the walls.
Is there some way to, maybe, set up an If statement so that it checks what the coordinates of the mouse click was and compares it to a set of pre-determined graphed points to decide what object was clicked?[code]....

I am using the MouseClick event toc change the image of a picturebox when it is clicked:
Private Sub PictureBox7_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox7.MouseClick
PictureBox7.Image = Image.FromFile("C:Documents and SettingsjacobscDesktoplogogoclick.png")
End Sub
The problem i have is that this tool will be used on different users computers and not just my own and at the moment when it is used on another computer it gives an error that it can'f find the image.
This obvioulsy happens as it is looking for my desktop, how can i change so that the image can be saved within the tool and therefore will work on other computers?

[code] I want to check checkbox and change color on one label and enter date on another.Then I want to uncheck the checkbox, restore the color on one label and clear the other..This works perfectly but only after the initial check. On the first check the correspsonding labels are handled properly but all the other labels are changed also, ie. the color changes on one set and the other set cleared.I can see the problem is in the Else If statements but can't understand why if the coding iswrong it works ok after the first check.

I have been playing around with the "MouseDown" event and have gotten stuck. What I need is for when you click on a label (for instance), the back color will change, BUT I also want it to change to another color (back to its original) when nothing is clicking it. I can change the color with one mouse click, but when I release the mouse button, it stays the color it changed and doesn't revert back.

I'm studying chemistry and wanted to make a quick app for studying the periodic table. What I have is 36 text boxes. I have a structure that can hold each of the 36 element's info, and an array with 36 instances of the structure.
Example:
Dim Elements(37) As Element
Structure Element
Dim strSymbol As String
Dim strElementName As String
Dim strNumber As String
[Code] .....
When I mess with it, sometime the text boxes will fill in, but randomly and the comparison between the input text and the info stored in the data structure never compare correctly. 90% of the time the structure data is showing a null.

I want to change the border color of a textbox. I have tryed to override the onpaint event (setting userpaint to true), but in this case I must control all the painting events of a textbox. So, this isn't a good thing. This seems to work, but the user control has no text property. And I woult like to override the gotfocus and the lostfocus events.

I'm trying to gather some WMI data, search that data and depending on the results change the color of a textbox and append some text.I can acheive this using a select statement but was hoping there is a more elegant solution as what I have generates a lot of similar code At the moment, the WMI data contains two properties I'm interested "State" and "ReplicatedFolderName". The"State" value determines the color and text that goes in the text box, however there are different textboxes for each replicated folder name.What I have which works is
