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?

Asp.net - .Net Iniatialising A Class Using System.Reflection And System.Type To Create A Session Based Singlton Extension Method
Jun 11, 2009I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

Auto Expanding In Height Textbox?
Mar 29, 2009Iam trying to convert all my access database into Sql Server databases and also create vb .net application for them all. First problem I encountered was there doesn't seem to be anything like a continous form(I know there is a datagridview). So i thought i would create a flowlayoutpanel. Place lots of textboxes on it and fill each of textboxes with information form my dataset. now on to the problem. one of the textboxes is the item description field. This field can have one word or many words. I have been trying to get the textbox to auto expand in height to cover the text. Below is the code I have put together to try and get this to work correctly.
vb.net

Forms :: Dynamically Expanding Shape?
Jun 10, 2010I am trying to get a line to expand whilst the user hovers over a specific Label or Button, I thought the best way to do this would be using a however so far I cannot get the process to loop until the user stops hovering over the item.
Public Class Form1
Dim Sec As Integer
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Sec = Sec + 1
[code]....
That is pretty much what I have so far, it works however I have to keep hovering and then exiting the Label for the size to increase. I have tried various loops however most of them just end up in an infinite loop.Just to clarify, I would like the X2 dimension of the Line to increase until the user stops hovering over the form.
VS Display Integers Expanding 1.1 To 1.1000000000000001
Mar 1, 2011This is, at least for me, most bizarre Visual Studio 2010 behavior ever. I'm working on MVC3 project, I copied a line of code from another project (VS2010 also, MVC1 if it matters) which looks like this: [Code] Now, if I type 1.2, it's fine, nothing happens, but if I type 1.12 it is expanded to 1.1200000000000001. Both target_height and height are integers. Why does one Visual Studio display 1.1 while other expands it to 1.1000000000000001? What is going on?

C# - .NET Expanding An Image While Preventing Clicks On The Form?
Dec 15, 2011I am developing a WinForm application using VB.NET (I am fluent in C# as well, so post in whatever language) and have run into some trouble. I have an image on my form that I would like to expand when clicked on. I have all that logic set, but I want that when it expands, the user has to click on an 'X' in the upper right corner of the PictureBox to close the expanded image. While the image is being displayed, I don't want the user to be able to interact with the rest of the UI on the form.
Basically I need something along the lines of (pardon me for switching to HTML but I know this works there) creating a div that covers the whole screen, making it opaque, putting another div on top of that, and then putting the image and the 'X' button on top of that. I have tried using opaque forms (didn't work), and panels with a transparent backcolor (didn't work either). I've resorted to taking a screenshot of the form, setting it as the image of a PictureBox, and putting the PictureBox on top of that. However, that seems like way to much overkill.
My current layout is MainForm -> Dynamically create new Form and add it to Main Form -> Add PictureBox to Dynamic Form and set its image to be a screenshot of MainForm -> Add a PictureBox on top of that PictureBox and set its image to the expanded image that I want

Jan 19, 2012I'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.

Jul 1, 2009The First Question is not that important but you know that when you click on 'Favorites' in IE 8 a form thing comes up? Well I've been trying to do that for a long time but I can't figure out how. 2: In IE8 when you expand the window and collapse the window, the toolbars expand and collapse as well. How do I make my tool bars in my Web Browser do that. 3: I actually have a third question and that's, How do you make a horizantal scroll bar on your web browser control. (just like in Internet Explorer.)
