Forms :: How To Create MouseOver Event At Runtime
Jan 6, 2012
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 writing in VB.Net.

Background: ok I have an app that hides in the system tray. During its operations in the background it can try to invoke an outside app several times.. and I need to track when the call errors out.. I was using messagebox's but for some reason if the app hidden the messagebox's dont come up and goto the forefront. So in reading about this I read I should just use a form to do it.. so I did.. works fine.. well works fine for one error.. but if the user tries to do 3 of the same operation.. and lets say first errors.. second works and third fails.. using one error form wont work.. since I diaplay the error one.. then need to display error 2.. I need 2 error forms so they can click OK on both.[code]...

Can I create a tooltip that will show up when a user moves his/her cursor over an image? I can't find such a property in Visual Studio, and I've scoured Google to no avail. I'm using an image in a PictureBox.

I'm pretty sure i'm not doing this right but i hope by asking this someone can show me the right path.I've created a function that creates a label and 7 checkboxes arrays . So depending how many names i get from my database, it creates that many for the label and the other checkboxes.
Now my function is inside a module which i call in my Class Form during "Load".
So what i want to do is be able to code in an event where the user checks on one of these

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 have a vb.net windows form app that I am deploying as using the visual studio deployment project. The app needs to write event logs to the application log in the event viewer. For reasons explained here I need to create the event source during the installation process. Something like this to run as part of the installer
If Not EventLog.SourceExists(My.Application.Info.ProductName) Then
EventLog.CreateEventSource(My.Application.Info.ProductName, "Application")
End If
That code needs to be run during the installer with elevated privileges. So my questions are:
How do I execute that code above as part of the installer? How do I get the installer to do the UAC prompt to allow that code to run as part of the installation?

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

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.

I 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.

During 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.
ublic Sub resizebuttons()
Dim X As Integer = 175
For Each item As String In CSVInput.selected
