Asp.net - Cannot Call Event Directly
Mar 27, 2012I have a piece of code:
[Code]...
Public Event Closing(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

I have a MouseMove event handler
Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
how do i directly call it, even if the mouse was not moved?
I tried..
Form1_MouseMove(sender, e)
but it did not work...
what is the error in the bleow: 'Public Event OnFilterAdded()' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event. Note: the error line is italic underline

So I am having an issue where I want to call a variable without addressing it directly and I get an error for it:
Conversion from string "player1BuzzLock" to type 'Boolean' is not valid.
This is technically correct but why would it fail?
Dim player1BuzzLock As Boolean = False
Dim PlayerNum as Integer = 1
'...
Dim playerBuzzLock As Boolean = CType("player" & PlayerNum.ToString & "BuzzLock", Boolean)
I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?
View 3 RepliesIn VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp
Now when I migrate to .NET I changed the KeyUp event to Private Sub textBox_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox.KeyUp
How can I do this call textBox_KeyUp(-1,0) now from textBox_MouseUp event?
how can i call a treenode mouse click event from any other key down event?
View 3 RepliesI have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

I'm making a button via images, which changes appearance as the user uses the mouse. For example, when the user clicks on the button, the image changes into the button being "pushed in." My problem is that when the user presses the button and releases the mouse I want it to go back to the image when the user is just hovering over the button. This only happens if the cursor is move off the button and then moved back onto it. I'm trying to call the event/sub where the mousehover event is used in order to get it to change back to the desired image. How do I call this event and/or sub in order for it to work?

I have a menu item in a program that I'm working on called "mnuFileSave" The Click event goes through several "housekeeping" functions and calls the correct "Save" function.
Another menu item performs a function and depending on the results may want to call the "mnuFileSave".
I have tried RaiseEvents mnuFileSave.Click and get the error "mnuFileSave' is not an event of 'The_Entertainment_Collection.frmCollectionBook'
I have tried Call mnuFileSave.Click an get the error "Public Event Click(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event."
I have a datagridview and a toolbar. If the user doubleclicks a row in the dgv, it shows the details of the selected row. I have a button on the toolbar too, it is for the same raison (also for showing details). But I don't want to duplicate the code and I don't want to make an evenet, and call this event, when the user clicks on the toolbar button or doubleclicks on the dgv.I want to call the datagridviewcellmousedoubleclick event, if the user clicks on the toolbar button.This doesn't work: dgvszamlatukor_CellMouseDoubleClick(sender, e), because e is a simply system.eventargs, but I need a datagridviewcellmousedoubleclick eventargs.

I'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .
I never did custom events and would like to make a sub procedure execute via a custom event from another form that does not have the custom event defined. For example I would like to raise the event from my ok button in one form and have the event in the other form execute. How to set this up using code examples?

I have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind. Each of the divs must pass it's own ID to the function. I can't use web methods as the function needs to identify which div was clicked and then show/hide/populate other controls on the page.
