Currently, when I double click on my current list, even if there isnt an item at the current mouses location, it calls the event and uses the last highlighted item. I know it is possible to fix this by using a selected index change event, but I require the list items to be double clicked

I have an ActiveX component (for mapping) I am using that I need to do an action on a mouse click, but the event isn't exposed. Internally, the class seems to fire an event, as it has a LastPointClicked() method that you can call that returns the map coordinates of the last point you clicked on. I am trying to find a way to center the map on the point clicked. I could fudge it with some kind of timer that just checks to see if the LastPointClicked has changed and center if it did,

I've noticed that in VS2008 the Mouse_Click() event is not firing for the right mouse button.I create a standard WinForms button called "btnMouseEvents". Wire up the MouseClick event. The event fires for the left button but not the right.
Private Sub btnMouseEvents_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles btnMouseEvents.MouseClick
MsgBox("Mouse click. Button = " & e.Button.ToString())

I am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?

View 4 RepliesI have a class called solution. This class has a property named cost. I also have a class called solutionList that inherits List(Of Solution). I have an instance of the solutionList class in another class called solutionGroup. Within the solutionGroup class I have a property called totalCost that sums the solution.cost property for all solutions in the solutionList.
But, I need a way to know when the cost has changed so that I can recalculate the solutionGroup.totalCost. I've added events to the methods that add or remove solutions from the list but I need a way to know if someone does something like
SolutionList.Item(0).cost = 100.
How to raise an event when the cost property of a solution that is in the solutionList is changed but with no luck.
Here is my solutionList class:
Public Class solutionList
Inherits List(Of Solution)
Friend Event listChanged(ByVal sender As Object, ByVal e As EventArgs)

I have a form, and the background color of the form is set to the transparency key, making the background of the form transparent. The problem I'm having, is that the form cannot recognize the MouseClick event (when I click on the transparent background of the form). I figured out that the transparent background is triggering this problem. When I shut off the transparency, everything works fine.My question is.. Is there any work around? I still need to use the form to be able to access certain objects that are rendering there, so I don't think I could use something like a "Panel" for example, because the objects will render underneath and possibly make them inaccessible.
View 5 RepliesI have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

View 2 RepliesI have a custom (inherited) TabControl which adds Drag/Drop functionality to it, so that one can drag the tabs around, either within the same control (to re-order them) or to and from other TabControls. I've noticed some time ago that my TabControl however was not raising its MouseClick and MouseUp events (or actually: it is not calling its OnMouseClick and OnMouseUp methods, which comes down to the same thing). I've been struggling with this problem for a long while and I finally figured out what is happening. I'm no closer to figuring out what to do about it though... The problem seems related to the drag drop functionality. I have this code in the OnMouseDown method (which is raised as usual):

I am having problems removing an item from a List(Of Integer). I see you can remove it by doing a remove with the index, but I assume you can do some type of function where you provide the value that you want to remove and it removes it. I found it on the List(Of String), but not Integer.

ok so heres the scenario. Ive made an app in visual basic 2010 that calls another application in c:pinger 2.0. In the directory pinger 2.0 are many sub folders from 15-500 named 15-500. I have a button that does this:Shell("c:pinger 2.0" & TextBox1.Text & "pinger.exe")
so basically if i type 15 it launches c:pinger 2.015pinger.exe which works flawlessly however this pinger.exe requires a host file thats .txt based. My problem is when it launches pinger form subfolder 15 it cant locate the hosts.txt. To do a little troubleshooting i loaded the hosts.txt file in the same directory as my VB app and then it worked just fine but this is no good.the whole point of having different subfolders is because each sub has a different hosts.txt file.So what im experiencing is when i call pinger.exe its looking for the hosts.txt file in the root of the VB application and not the subfolder 15-500 is there a way to call a program and let it run from its original location so it will find the hosts.txt file in the correct subfolder?
i can upload my project if this mumbo jumbo has confused you, perhaps theres some ,vb"switch" i can run? like:Shell("c:pinger 2.0" & TextBox1.Text & "pinger.exe",vbrunwhereyoursupposedtoplease)
I have a form which has a button and a toolbar.
The button has code which works and deletes a record in a database:
=======================================
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
[code]....
I can put similar code into the toolbar button just changing the Button5_Click to the name of the toolbar button but I thought it would be better if I 'called' the already written code.
I changed the Private Sub Button5_Click etc. to Public Sub Button5_Click then in the Toolbar button click event I put 'call Sub Button5_Click()'
I get errors stating that ' argument not specified for parameter 'e' ' and can't progress.
I will be using this code in a few other forms so would like to 'call' possible.
