I have an list of controls(PictureBox) and I need to know which one of them is selected, meaning over which of them the mouse is. I thought about getting the location of the mouse and then comparing it with each PictureBox location, but it is quite slow.

View 4 RepliesI'm an old Access developer and know VBA quite well, but now I'm working at learning VB.net. I'm trying to find the equivilent of the following Access VBA code using VB.net:
Function EvalField()
Dim x As Integer, ctl As Control
Set ctl = Screen.ActiveControl
x = Val(Mid(ctl.Name, 5))
Screen.ActiveForm.Controls("Formula" & x) = ctl
ctl = Eval(ctl)
UpdateTotal
End Function
This code sets a control variable to the currently active control, then copies the text from that control into it's matching "Formula" field for reference by the user), then turns the string of math into the answer. For example, if the user enters 5 + 4, that will be copied to the Formula textbox, then it will be evaluated and the answer will replace the 5 + 4. And lastly, the UpdateTotal sub will execute which will add this answer to the existing Total field.

View 4 RepliesI need a function that returns a control within a form based on a string name. I've tried Jim's method here, but then found out that it will not work with SplitContainers. Therefore, I feel like I need to use a recursive function, or maybe a stack. I've tried many different examples online, but I can't seem to get any to work.
This is the code for the latest try, as taken from here:
Public Function FindControlRecursively(ByVal ParentControl As Control, ByVal ControlTobeSearched As String) As Control
Dim FoundControl As New Control
For Each CurrentControl As Control In ParentControl.Controls
[Code] .....
Note that the above code only seems to return a blank control.

View 1 RepliesI want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

The problem is, is that this code just moves label1. What I need it to do is to move whatever label is selected. The user could create an infinite amount of labels and I do not want to repeat the above code an infinite number of times. Is there a way to make the label selectable, and if it is selected, it uses that name in replace of label1?
I have this program that should execute a piece of code base on the tab that is selected. How do I do it?I've tried:if tabcontrol1.tabcount=1 then 'Execute this code'

What is the appropriate declaration such as "ValueChanged" or "Click" for a NumericUpDown that will execute the code when I press enter. I already know that setting the "AcceptButton" property of the main form to a default button will not work, especially if I want a different button to be selected depending on which control I give focus. How do I accomplish this?
