I always get worried and my layout when i code. I always get myself in a flap when coding and worried i should be doing it different.What i am going on about is not the code it self. But where i actually put the code.
What i am thinking about is functionality (does it matter if formload code is at top/bottom/ or even middle)
And read ability. Do i put all button events into regions?
When you set a region equal to another, or set it equal to a new instance, do you have to call dispose on the region, or does VB do that? (I guess this isn't necessarily specific to regions)
ex:
'at some point in the code a region is created
Dim Rgn as New Region(SomeRect)
'....
[Code].....
If Rgn now points to the Rgns(0) clone, what happens to the original memory created by "New Region(SomeRect)"? Do I need to call dispose on Rgn before assigning it to the the Rgns(0) clone?
I'm getting an error when changing a picturebox region in a timer_tick event.

I know i can collapse all regions with Ctrl+M, Ctrl+O - but that also collapses all of the subs/functions/properties etc within the #Region.if it collapsed all of the sub regions too - just not the subs etc.Is there a way to collapse all top level regions only? Maybe an extension?

I'm refactoring VB.NET code where methods routinely run five hundred lines and the references are so tightly coupled that the code defies simple refactoring such as method extraction. And that's why I thought I would try regions within a method body. I just wanted to organize the code for the short term. But the IDE didn't let me (resulted in a compiler error.) I'm just curious as to why? Seems like code regions shouldn't impact the compiler, intellisense etc. Am I missing something? (Still using VS 2005 btw.)
Interesting: This seems to be language specific. It's OK in C# (I didn't check that initially) but not in VB.NET.
public module MyModule
Sub RunSnippet()
dim a as A = new A (Int32.MaxValue )

that gets a compiler error but the C# version is ok.
I would like to create an interface that brings with it it's own private variables and regions.for example, if you create a class and implement IDisposable, you get all of the following:[code]
View 3 RepliesI've been having several problems lately with clients that are using a different Windows Region setting than I am. The error is as follows:
The type initializer for 'InventoryDataTable' threw an exception. ---> System.TypeInitializationException: The type initializer for 'InventoryDataTable' threw an exception. ---> System.FormatException: String was not recognized as a valid DateTime.
The error occurs when users load the application and their region settings do not match my own. The application loads up a dataset and attempts to receive a small amount of data before allowing the user to log in. When this is removed, the problem occurs immediately after the user logs in to the app. I cannot seem to find the proper settings to force the user to use either my Region, or to allow the application to figure it out on it's own...

I have made an click event for a button which creates buttons dynamically and I added events to the dynamic buttons by using addhandler but it says it the button is not declared. Here is the code for dynamic buttons:

I have a MyUserControl in which I have Button1 and Button2 buttons. I need to "delegate" that button clicks to the MyUserControl's Button1Click event and Button2Click event respectively. Below is a stub I don't really know finishing...

Private WithEvents Button2 As Button
Public Custom Event Button1Click As Eventhandler
AddHandler(ByVal value As EventHandler)
AddHandler Me.Button1.Click, value

I wonder if I need the WithEvents in the buttons declaration, and how to achieve the RaiseEvent part...
In Visual Studio C# (2008) ctl-M-L expand all the regions. There's also a setting in Text Editor->C# ->Advanced to not collapse during file open. I see no equivalents in VB.NET.Is there a way to expand all the regions, not just the one which has focus in VB.NET.

View 7 RepliesI'm just wondering how I can make a custom button, but have it inherit the regular button? I just want to change the way it looks, and change the button hover/click events
View 3 RepliesIs it possible to have multiple click events for a button based on the button text? In other words, if I change the button text can i create a new click event based on that text but use the same button?
for example:
button1.text starts as "steel"
button2.text starts as "brass"
If I click button1 then the text would change to:
button1.text="Stainless"
button2.text="Cold rolled"
If I click button1 again a string would then be added to a textbox and the process would start over again. can I have a different click event or would I need to put an If/Then or Select/Case in the sub to handle this? I have 10 buttons I would need to do this with and each needing at least 3 different choices for each depending on the previous button press.
what are some helpfull source codes to set button click events and to use them to open uther programs .
View 1 RepliesI want to add a custom property to a button in window form. Currently i am using following code to create my logic. but i want to create an enum value for a button control.

I have created a simple custom control - we will call it a "panel with buttons". Here is how I instantiate it:
[Code]....
So what I wind up with are multiple instances of my panel. Each of these panels has a button on it called Button1.
My question is - how do I capture this button event in a way that I will know which panel index it came from?
In the custom control there is only the Button1_click event - and when I click on it in any of the multiple panels I manually instantiated the event does occur, but how I can tell which one of my instantiated buttons were clicked...
in a winform, in vb net,I have a list view with hoverselection set to true. I start a drag and drop operation when the mousedown event is fired, but it's fired only when i release the mouse button on the control or on the dropped control!
is it a normal behavior?
I have an application similar to calculator, with button from 0 to 9, Enter and Clear.

View 4 RepliesI found some threads talking about this.. but when I follow the thread on where to do it.. it must be talking VS2005.. cause on vs2008 in project properties -> application tab-> I dont see View Application Events button. so I assume its moved in VS2008 ? I did find some code I guess to do the same thing.. but I wanted to make sure I do it correct.. since I have an app that a client is running and they keep getting framework exceptions and I have no clue where its coming from.
View 18 RepliesI have a windows applications. Form 2 is child form of Form1 . Basically when button on form2 (child form) is clicked, it raise an events, which writes something in testbox on form1 (parent form). This is my code
parent form form1
Public Class Form1
Public mycount As Integer

This is the first time I am tring to use events.. I am not sure what's going wrong.. the textfill event is never called from form1.
Problem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !
Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form
In that case, you may use a code similar to this
Event BeepIt()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent BeepIt()

View 4 RepliesI'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.
