VS 2010 : Control The Looks Of The Button Properly?
Oct 30, 2010
I'm making my own winforms button, mainly to be able to control more aspects of a regular button. So far, I've figured out how to control the looks of the button properly, but now I need to implement the changes I've made. I can draw what I have so far, but it flickers even with double buffering...
Inherits System.Windows.Forms.Button
Protected Overrides Sub OnPaint(ByVal pevent As System.Windows.Forms.PaintEventArgs)
MyBase.OnPaint(pevent)
[code]....
So far I just want to get my gloss working.I'd also like to know how to control some of the more tedious properties of a button, such as corner radius and how I can make the flatstyle of the button "Flat" all the time without the option to change it (this is so that I don't have to worry about borders and stuff).

I got this timer tick function: Private Sub controlTick(ByVal sender As Object, ByVal e As EventArgs) Label2.Text = (Control.ModifierKeys = Keys.Control) End Sub
That is supposed to make my label say "True" if I am currently holding down the Control key, and "False" if I am not.But, how come my label is always "False"? What is interesting is that if I press the Control key at lighting speed a bunch of times I can see for a fraction of a second "True", but immediately turns to "False".
Timer ticks every 50ms.

I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

I'm working on a game for school, and having a bit of trouble getting keys to control movement properly. When I press down the correspondant arrow key to move the picturebox, it moves the picturebox once, then stops, waits, and then starts moving again continuously (like when you hold down a key in a word processor and it stalls for a bit before repeating the character).the code I'm currently using to move the picturebox is (moving it left as an example)
Private Sub Form1_KeyPress1(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyCode = Keys.Left Then
Dim x, y, x2 As Integer
[code]....
how to remove the delay and head straight into the consistant movement?

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

Working with a form that has a menu, toolstrip and Crystal Viewer control. I cannot seem to get the viewer to maximize properly without hiding the toolbar of the Crystal Control behind the menu and toolstrip. I've played with the options of Dock and Alignment, as well as autosize and I just can't get it to work.So do I need to handle the sizing myself to do this and position the control where I need it?

I have a progressbar which receives the amount of Sub directorys within a main directory as a Maximum value and when i run the program It goes through the directorys to grab all the files within the subdirectory.
This is the code below which is updating the progressbar.Foldercount is an incrementer which increments by one for each folder it enters.
Dim percentage As Double = folderCount * 100 cirFolderCount.Maximum
cirFolderCount.Text = percentage.ToString
cirFolderCount.Value = Convert.ToInt32(percentage)
On the test directory which has 4 sub directorys I get a maxvalue of 4 and the min value is set to 0 The code above returns the value of 25.0 when entering the first folder which is correct (25% of 4 is 1),But the progressbar does not fill 25% of bar once this folder is processed.

I have my own control which inherit System.Windows.Forms.Control The only functionality that this control requires is the capability of losing and gaining focus. I learned this requires the control style of selectable to be applied which is descriptive as exactly what I'm in need of, "If true, the control can receive focus.".
However after applying this style in my code, the control still refuses to have anything to do with gaining or losing focus. Other styles I have applied to this particular control are as fallowed
UserPaint, AllPaintingInWmPaint, and SupportsTransparentBackColor. I'm not sure but perhaps one of these other styles interferes with the one that's not working properly.

I borrowed part of this routine to download files, and it works great; except when I download text files the returns aren't written into the outputted file. I've tried different web request and techniques with no luck in solving the problem.

End A statement which as far as i know doesn't close you program properly and hides errors. Right now i'm being forced to use end because i don't know how else to close my program properly. I'm not sure where my problem is but some of you should be able to fix it. I'm trying to make a game using directx with a game loop. This code is the skeleton of what i'm making.
Public Class Form1
Private ProgRunning As Boolean = True
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show() 'Make the form appear
Me.Focus() 'Give the form focus
[CODE]...
This code runs alright because end is being used but if you rem end out the error which it's hiding comes out. The error is "Object reference not set to an instance of an object." I'm not totally sure but i'm guessing that the error is refering to the form.
