I have a form that depending on results from a table would create a number of buttons using code at runtime. This could range from 1 to 20 buttons. What I am struggling with is creating a generic mouse over event for each of these buttons? The reason why I want a generic mouseover event is that depending on the text on the button I would do certain things, instead of duplicating the same code in individual mouseover events.

i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this stupid question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e)
{
Label3.Text = "this is label three";

I create a rich textbox control at runtime. However, I have an RowEnter event procedure for a DataGridView control that needs to reference this richtextbox. I get the obvious error in the DV event prodedure saying that the richtextbox has not been declared. What do I have to do to allow this event to recognize this control even though it does not yet exist at design time? I realize the easy way around this is to hide the control on the form until runtime.
View 1 RepliesI have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.
Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.

I am trying to figure out out ttrigger a click event from a Picturebox object that is created during runtime? application that I am developing using Visual Studio 2008 during runtime a user selects a shape from a Panel3 on the right side of the form and then clicks on a location inside Panel1 where that shape is copied over. Almost like a Visio application but without the drag and drop.The name of my new shape via a is call "C_Object" I would like the user to be able to select this new shape and a click event to be raised but because this PictureBox object was created during runtime I am not seeing the event.
View 2 RepliesDuring the process of my program I am creating several different buttons depending on what file the user selects. I have been able to create these buttons and I would like to set up the event handler so when the user selects one of these buttons it pops up a message box that shows the user the name of the button they just clicked on. The message box isn't the goal of what I would like to do with it but If I could get that to work I would be able to alter the code to get it to work the way I want it to.
Below is my code that I currently have. I don't have the event handler doing anything at this time as I can't seem to get it to work I am still playing around with it.

I do have a customized treeview which inherits from treeview. The customized treeview offers - amongst other - the functionality to automatically check/uncheck the child and parent nodes according to the selected node.To do so, I use (or mabye abuse?) the AfterCheck-event of the treeview in the class where the inherited treeview is customized. Code looks like that (Submethods not included):
[code]...
I temporarily remove the AfterCheck-Event in the event-procedure to avoid it getting fired when I programmatically check/uncheck the checkboxes of the treeview. Works fine so far, only problem I see: if another programmer wants to use the customized tree view and tries to make use of the After-Check-Event, he'll get caught in an infinit loop, because his own After-Check-Event (he added himself to the treeview) was not removed and keeps on firing every time a checkbox is automatically checked/unchecked.
How can I remove ALL methods linked to AfterCheck-Event without knowing which method someone added to the treeview-control? My guess is to use reflection and to get the underlying delegate of the AfterCheck-Event by using the .GetInvocationList somehow - but I was not able to make it work.

I'm attempting to create a listbox when a button is clicked in Visual Basic 2008. I can't seem to find code that works to do this.
Dim lstOutput As ListBox
lstOutput = Me.Controls.Add("VB.Label", "List1")
Problem is that both of the things inside the parenthesis generate errors:For the first one:Value of type 'String' cannot be converted to 'System.Windows.Forms.Control'.And the second one:Too many arguments to 'Public Overridable Sub Add(value As System.Windows.Forms.Control)'.

For this test I am using the event viewer.
The system loades the logs into memory, and then creates however many system logs there are ie application, system security etc etc.
