Can MDI Parent Handle Mouseclick
Oct 6, 2011
With the following code, I am creating a child form when my main form loads:
Public Class Form1
Dim cForm As New System.Windows.Forms.Form
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Once it loads, the main form doesn't seem to handle the mouseclick event. Is that because the child fom is showing, and somehow IT has to handle the click event (even though I'm not clicking within the boundaries of the child form)?

What I want to achieve is, getting the current position of the mouse when it's clicked on the form (so also on any object on the form)I can get the position with (this code runs in Timer1)
Dim MousePosition As Point
MousePosition = Cursor.Position
Button4.Text = MousePosition.X & " " & MousePosition.Y
But how do I capture an an overall Click event, so when the mosue is clicked the timer stops?

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 been trying to write a utility program that enables you to click a certain number of times and having a specified program open up when that happens. Ex: If I consecutively click 5 times it will open explorer, 6 times will open outlook, ect.I have the entire program writen out, the only things thats stopping its completion is that I can only log clicks that happen ON the form, not on the desktop, or within any window (globally detecting mouse clicks, as opposed to only on the forum
Code:
Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click

For some reason I have always used the SelectedIndexChanged property to take action when something is clicked (I guess because this is the default property? ie when you double click the listbox this is what you get). However I have often come across problems when I try to unselect all the items in the listbox by calling

I have a treeview, and lets say in the treeview I have the nodes "Textbox1", "Textbox2", and "Textbox3". Also on the form I have 3 textboxes. What I want it to do is when I click "Textbox1" in the tree, to select all text and bring focus to the first textbox. So on the AfterSelect event of the treeview, I find out what node Im on, and what textbox to go to, then I say Textbox1.Focus() : Textbox1.SelectAll().When I use the keyboard and navigate to that node, it works. It jumps the focus off of the treeview and to that textbox, selecting all it's text. Works fine.But when I click on it with my mouse, it doesn't. It does select the text, bring focus to the textbox, but immediately brings focus right back to the treeview. (you have to look really close to see it) I'm thinking there's some mouse event that is bringing the focus back to the treeview, but not sure what.

I have spent the last hours trying to make an easy fix for this. Setting it to enabled=false is no good in this case. What I was looking for is a way to prevent the user to place the cursor in a multiline textbox. This is a read only textbox, and the user can't type anything in it, but for some reason he can still place the cursor in it, that is what I try to prevent.

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 trying to send a mouseclick via the code below and it works fine. But I was wondering how would I send a "virtual" mouseclick(It emulates a mouseclick at specified point but does not move the cursor)
Public Class Form1
Public Declare Auto Function SetCursorPos Lib "User32.dll" (ByVal X As Integer, ByVal Y As Integer) As Integer
Public Declare Auto Function GetCursorPos Lib "User32.dll" (ByRef lpPoint As Point) As Integer

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?

I have created a User Control and would like to be able to detect when the user clicks on the Form.I have seen this question which is related but the suggestion to use the the Leave event doesn't always do what I want because the focus doesn't necessarily change when the user clicks the Form (my control could be the only control on the Form in which case focus stays with my control).I want to be able to do something like this from within the User Control:[code]

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.

just trying to work out some functions, like time delays and such and autoclickers.What I have is two command buttons and one textbox, and what I want this program to do is make a mouseclick according to the time inserted into the textbox (in milliseconds). e.g say someone types in "500", after button 1("START") is clicked, the mouse will click every 500 milliseconds, and button 2 ("STOP") will halt execution. Also, would this continue execution in the background, if i have other programs open? I've been able to make a program that has a timer which ticks at the specified time, I just can't get it to make the mouse click, i've tried "cmdButton.PerformClick" but thats not working,

This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata
Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this
Protected Friend frmMain as Mainform
frmmain = new mainform
In frmMain I am doing this
Protected Friend frmsub as new Subform'
frmsub = new subform

I 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):

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 wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?

I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.
