How are your graphics shapes created? Are they separate objects? Are they created at design time or run time?
Assuming that the graphics shapes are objects that have their color as a property, you could have an event handler that handles all of the objects onClick events. In this event handler, you would examine the Color property of Sender.
If the objects don't have a color property, pehaps you can store the color in the tag property.
I hope this helps.
Roy.

Thanks. These are just drawings (circles, rectangles [DrawRectangle] etc) which are drawn at run time on a panel. When they are created I choose a colour to classify them and the easiest thing would be to click on the drawing and to test the colour attribute of the point that was clicked.
There are some pretty simple ways around it but I thought that clicking a point and retrieving its colour would be straightforward and that I was missing something.
Cheers

I'm looking for a solution to get the process name running an application. For example, i open a word document to generate a letter. The expected result is WinWord.exe.
I'm using VB .Net for my development.
Very much appreciate if can show me what is the API to use and the sample code.
Thanks a lot.

Process.GetProcesses()[^] might be of use to you. It'll return an array of Process[^] objects that you can use to find what you're looking for.

Hi, trying to learn how to interpret information from WinDbg and ProcessExplorer (from www.sysinternals.com). So, I wrote a simple Win32 console app in VB.NET (could have been anything else really):
Imports TestDebugger
Module Module1
Sub Main()
Functions.SubA(1000, 100)
Functions.SubB(1000, 100)
Functions.SubC(1000, 100)
Return
End Sub
End Module
Imports System.Threading
Public Class Functions
Public Shared Sub SubA(ByVal max As Int32, ByVal sleep As Int32)
For i As Int32 = 1 To max Step 1
Thread.CurrentThread.Sleep(sleep)
Console.WriteLine("SubA: " + CStr(i))
Next i
Return
End Sub
Public Shared Sub SubB(ByVal max As Int32, ByVal sleep As Int32)
For i As Int32 = 1 To max Step 1
Thread.CurrentThread.Sleep(sleep)
Console.WriteLine("SubB: " + CStr(i))
Next i
Return
End Sub
Public Shared Sub SubC(ByVal max As Int32, ByVal sleep As Int32)
For i As Int32 = 1 To max Step 1
Thread.CurrentThread.Sleep(sleep)
Console.WriteLine("SubC: " + CStr(i))
Next i
Return
End Sub
End Class
Now comes the questions:
1. WndDbg - how can I set breakpoint in WndDbg to break at TestDebugger.exe calls to Functions.SubA?
2. ProcessExplorer: Hey I located "TestDebugger.exe", double click and page to "Threads" tab and I couldn't see any calls to .NET Functions.SubA??? how come? Thanks in advance.
I captured the screenshots of information I got running WndDbg and ProcessExplorer.

I have a program, whereby i wish only authorised person can install it. Therefore, i tried to add serial number while i make the installer using Vb.net, however, i cant find the way to add the serial number in... Can anyone please help me to figure out? Thanks a lot..

NET Installer classes do not execute until the end of the setup sequence, and are not particularly useful for this kind of task. You need to use a custom action DLL that runs during the UI sequence instead.

Is there anyone has done it before or has ideas to solve it? please help.![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

I need desperate help. I have a status bar with 4 panels and four labels above and outside of the status bar each above a panel. When the panel grows/shrinks with text - need for the labels to resize accordingly with the panels. 
This is what I am trying now:
Private Sub ChkPause(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Checkpau.CheckedChanged
If Checkpau.Checked = True Then
'TxtFil_na.Text = "Program Paused " & vbCrLf & "Double Click Here to Start"
TxtFil_na.BackColor = Color.Red
StatusBar.Panels(1).Text = "Program Paused"
Else
TxtFil_na.BackColor = Color.LightGreen
'TxtFil_na.Text = "Program Running "
StatusBar.Panels(1).Text = "Program Runningggggg"
End If
End Sub
Private Sub Form1_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Resize
Dim panelWidth As Integer = Me.StatusBar.Size.Width / 4
lblsz.Width = StatusBar.Panels(0).Width
lblsts.Width = StatusBar.Panels(1).Width
lblFil_na.Width = StatusBar.Panels(2).Width
lblerr.Width = StatusBar.Panels(3).Width
StatusBar.Panels(1).AutoSize = StatusBarPanelAutoSize.Contents
End Sub

The problem is that you are changing the width of the labels, rather than the position of the label. What you want is for each label to change it's position as the panels resize. When panel(0) gets bigger, panels 1-3 move to the right to make room for it. This is not how the labels work, however. Each label has a Left property. As panel(0) gets bigger, you want the labels for panels 1-3 to change their Left property, so that they move to the right. Perhaps something like this:
<br />
lblsts.Left = StatusBar.Panels(0).Width + 3<br />
lblFil_na.Left = StatusBar.Panels(0).Width + StatusBar.Panels(1).Width + 3<br />
lblerr.Left = StatusBar.Panels(0).Width + StatusBar.Panels(1).Width + StatusBar.Panels(2).Width + 3

I am a beginner to programing and have a project where I want to select a file for output. Currently I have it set up to mannually type in the path, what I need to know is how can I code a button to be able to navigate to a directory and provide a file name and pass that back to my input box? Thanks in advanced.

In the dialog meanu there should be an open file dialog. Add one of those to your form.
On your buttons click event, ( Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click), add this code (assuming name of open file dialog is openfiledialog1)
<br />
Dim FilePath As String<br />
Dim Input As String<br />
OpenFileDialog1.ShowDialog()<br />
FilePath = OpenFileDialog1.FileName<br />
'Filenames means multi-select; to open more than one<br />
Input = InputBox("Something", "Title", FilePath)<br />
You get to select the path from a dialog, and you use a string to pass it on to the input box, no error handling included.
Inputbox has optional sections, and default and title are included. So you can optionally add a default input.

NEED: .NET multi-table master-detail type customizable forms and datagrid generator or at least easy-to-follow idiot-proof instruction. ASPMaker.net ain't got it. ASPRunner.net ain't got it. Those tools are great for quick easy creation of add, display, edit, copy, delete, search database connectivity and functionality but for only one table!! I need to do all these quickly using data from three Oracle database tables (will also need to consider furture use for MS Access tables). Any intelligent leads appreciated. My database is small with only about two dozen total fields and only two master-detail relationships - not that big of a deal, it would seem. But my search has turned up nothing usable so far. Grateful for any and all good ideas. Programmers, freelancers, all responders/responses welcome. I just need to get it done in a hurry!!!
Thanks all!!

Can anyone suggest a good third party combobox? The combobox needs to be able to do the following:
Automatically fills the text at the cursor with the value of its dropdown values list. As characters are typed, the ComboBox finds the closest matching item from the list and automatically fills in the remaining characters. Appended characters are highlighted so that they are replaced by any further typing.
Any help would be appreciated.
