Interface And Graphics :: Making A Custom Class That Mocks The System.Drawing.Rectangle Class?
Jul 6, 2010I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?
Public Class Rectanglar : Inherits UserControl
Public BackgroundColor As Color = Color.Blue
Public Sub New(ByVal name As String, ByVal XY As Point, ByVal Widthy As Integer, ByVal Heighty As Integer)

View 13 RepliesInterface And Graphics :: Link A Class / Object To An Interface?
Apr 21, 2010I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
Interface And Graphics :: Anchors In Custom Controls?
Oct 21, 2008I'm having some problems with custom controls and anchors today. I made a custom control containing a picture box and a vertical scroll bar. When I adjust the form the custom control outer area (the blank part) will adjust to the size of the form but the picture box and scroll bar do not. I have the picture box anchored to all sides and the vertical scroll bar anchored to the right side. They just will not adjust with the control when it is resized on the form.
View 4 RepliesInterface And Graphics :: Custom ListBox Control
Dec 8, 2009I'm trying to build a custom ListBox control as inspired by the 'Audi Infotainment System' on high-end Audi vehicles. The only difference is i would like to have a 'boundary' where when scrolling up/down moves the actual list up or down. Basically, i would like my list to act like a normal ListBox except i would like to show say one or two items above and below normally only visible items.
View 3 RepliesInterface And Graphics :: Custom Right-Click Menus?
Oct 29, 2008I'm trying to bring up a simple right-click menu on a listbox and I'm having little luck with it. I created a basic ContextMenuStrip named "ContextMenuStrip1" and I'm trying to call it in the ListBox's Mouse Click method:
Code:
Private Sub ListBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseClick
If (e.Button = Windows.Forms.MouseButtons.Right) Then
ContextMenuStrip1.Show(MousePosition)
End If
End Sub
So here's what it's actually doing. The right mouse button doesn't seem to activate MouseClick at all for this object. It is caught in MouseDown, but when I try to call this from that method, the ListBox Index doesn't change. How can I get a right-click to be called from the MouseClick (Not imperative) and how do I get the ListBox to change the index with a right-click?Also, the menu looks like one of Office's right-click menu that can have an image to the left of the text. When I don't have an image the text is about 50 pxls or so away from the left edge. This looks weird. Can I change that?

Interface And Graphics :: Scrollbars Button Size?
Jan 13, 2011I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250.
So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right?
But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?
Interface And Graphics :: Way To Have A Button / Label That Would Change
Jan 11, 2009I was wondering if there is a way to have a button/label that would change the selected item color of the combobox from the standard black into a certain color (say green), but not change all of the items' color into green. This is for a to-do list type of application where a user clicks the button to signify that the current item is finished..This is what I was thinking (not in VB code) When button1 is clicked, combobox1. selecteditem. color = green

Button_Play.BackColor = ColorDialog.Color
There is a reset button to put the colors to how they were without any special coloring, but I can't get them to go back to how they originally looked.They go to gray in the middle, instead of the nice shaded blue/gray style. I have tried a few different things:
Button_Play.BackColor = Button.DefaultBackColor

Button_Play.BackColor = Color.Empty

Interface And Graphics :: [VB2005] Enable Import Button In The GUI?
Nov 20, 2008how to enable the "import" button when at least one of the checkboxes is checked.I have two buttons : "Deselect all" and "Select All" for the checking of the boxes, to import the specific files' data they want to Excel. (the files are in listbox, and the checked boxes is for selecting the files' parameters that they want to see in excel)
One option:When the user deselect all, the "import" button is suppose to be disable to prevent the user from importing the files' data parameters.
2nd option:(if i do not want to disable the import button) or show message that they have to select at least one box and at the same time, prevent the import button to work if there's no checked checkbox. So my deselect all button code :
Code:
CO2checkbox.Checked = False
NH3checkbox.Checked = False
DBcheckbox.Checked = False
[code]....
but the button still remain disabled if I click "unchecked all" button and then checked at least one box. how do I enable it?And how do i...show error message and prevent the files' data to be imported when the user click "import" when there's no checked checkbox if I choose the alternative option of using message to alert them without disabling the button and yet prevent importing of data?
PS: If I did not click "deselect all" button but click the "select all" button, the import button is enabled and working.
Interface And Graphics :: Best Way To Make A 'tile Selector' Box?
Jan 16, 2011So now I will try to make something more complex, still playing around with this graphics thing.I want a picturebox to display a tileset (a bunch of 32x32 tiles normally used for creating game levels etc), the picturebox is inside a container (which has autoscroll ON). The picturebox is larger than the container, so the container will make scrollbars automatically.Now, I need to be able to choose a tile or multiple tiles (if I click & drag the mouse)Basically I want to draw a 32x32 "red" box over each selected tile (so the user knows what tiles are selected).So first of all, I need to know when the mouse clicks the picture. Good. It works.Now, I need to know which 32x32 tile was clicked. Well, I think I can calculate that just fine.BUT, what if the user drags the mouse while clicking on a tile? I want to support multiple tiles selected, but I am clueless about tracking what tiles were chosen.If we solve that problem, I would have another curiosity: You know the "red boxes" that tell you which tiles are selected? What would happen if I dragged the scroll bar? I need the redboxes to move along with the picture, and hide if they go to an invisible area.

Jul 11, 2004I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

Interface And Graphics :: Disabling Button Before Executing VB Code To Prevent Duplicate Records?
Aug 5, 2008I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases. After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
[code]...
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
[code]...
But although this works, it does not execute my VB code in the code behind page so I am a little confused where to go here.
