'Graphics' Not Part Of System.eventargs?
Feb 15, 2011I am researching ways to use vbTab and Tab stops to create a report in VB 10. I found some code that demostates the tab methods. When I plug the code into Visual Studio 10, I get 'graphics' not part of System.eventsargs, referring to the g.graphics.drawstring command. I have tried several different imports statements with no success.

ByVal Sender As System.Object - ByVal E As System.EventArgs
Jan 25, 2011Just as a secondary question, usually I reduce: -(ByVal sender As System.Object, ByVal e As System.EventArgs) to just () for most occurrences of auto-generated subroutines. Is there any harm in doing this? I cant see any reduction in performance but do get more readability.
View 8 RepliesAre .net EventArgs Maintained At A "system" Level
Apr 9, 2010I have a custom developed control I am using that somebody else wrote. For some reason, when the control was written, they did not write an event handler for the "mouseDown" event so when I mouseDown on the control, no event is fired. What I am basically trying to do is capture which mouse button (left or right) is pressed when the control is clicked on. Is there any sort of system level objects that maintain system state (including which mouse buttons are currently being pressed regardless of the control being clicked upon?)

How do I do this? It's always just one tab working and the other doesn't.
View 4 RepliesCreate Overview 'outline' Of Most Important Sections Of An App In Program?
May 1, 2009I want to code in our VB.net to be a little easier to follow both to improve readability and also make it a lot easier to know the best place to put a new bit of code/feature.
Essentially, I'd like to have a 10,000 foot "outline" of the code" with hyperlinks from the outline to the code.
It needs to be portable, so BookMarks won't do the trick (I think). I'm thinking maybe TODO comments. I'd like to create our own Todo style comment like "Outline" or something but that keyword would need to be in the config file for VS as well (but then it's just one thing to keep sync'd).[code]...

Oct 29, 2011As this is my first post on this website, hello to everybody from Thailand where I work as a school administrator.I wrote last year my very first full application in VB6.Why VB6? Because I have the program and because I am using VBA since Excel supports it, say around 1995. I am now in the process of upgrading to VB.Net, ADO.Net and SQL Server.I have a form that can be called by three different menu points for three different purposes, and I need to know which menu is at the origin of the call, as the form has to behave accordingly.

Asp.net - .Net, EventArgs, ByRef And ByVal?
Dec 15, 2011In VB.Net, I have an object named WorkflowButtonEventArgs that inherits from System.EventArgs.The WorkflowButtonEventArgs class contains two ByRef Properties. These are objects that are in memory, and I do not want them duplicated or copied in any way.
Can I pass the WorkflowButtonEventArgs object ByVal in VB.Net and have it still preserve the two ByRef definitions in WorkflowButtonEventArgs?Specifically, if I pass it ByVal:
Dim e As New WorkflowButtonEventArgs e has some ByRef properties RaiseEvent SomeEventName(e) ' e is passed ByVal Will the ByRef Properties/Members in e (WorkflowButtonEventArgs class) not be copied or duplicated in memory?
Long-story-short: Can I pass e ByVal, or do I need to pass it ByRef since it contains ByRef Properties?

Create EventArgs And Return Value Similar To FormClosing?
Dec 6, 2010This is for a WindowsCE project,
Windows WM6 does not allow you to hook in WndProc easily as this has been hidden, I've built a class that inherits from MesageWindow, which allows me to receive Messages as intended.
What I'm trying to do is create an event that will return a value Boolean bypassing base.WndProc(ref m);
basically saying I've handled the event it does not have to, similar to how the Form_closing event would work e.g e.Cancel will cancel he closing off the form.
I've not finished my WndProc function as of yet but you should get the picture.
Code:
public delegate void WndProcEventHander(object sender, WndProcEventArgs e);
public event WndProcEventHander OnWndProc;
protected override void WndProc(ref Message m)

Handle EventArgs On Variable Or Not Yet Created Controls
Dec 6, 2011I'm trying to add subs that will handle MouseOver events on textboxes that don't get created until after the program starts.
Each textbox gets created with a unique number attached to it like this...
AptTextBox0
AptTextBox1
AptTextBox2
etc...
Depending on how many are needed. But I never expect more than say... 15 at any given time.
Is it possible to handle MouseOver (or any events for that matter) if they don't exist until later.
I tried this but it didn't work....
I added this is the Designer code....
Friend WithEvents AptTextBox0 As System.Windows.Forms.TextBox
Friend WithEvents AptTextBox1 As System.Windows.Forms.TextBox
Friend WithEvents AptTextBox2 As System.Windows.Forms.TextBox
[Code]....
But it doesn't do anything. I don't get errors, but apparently it's still missing something to properly handle the events.
