Sizing Box User Control

Mar 18, 2012

I am writing a control in vb.net that will allow a user to resize something. So far, resizing works, but I can't get moving to work properly, instead of moving where the mouse moves, it seems to flicker between two positions, but I can't figure out where these positions are coming from. It follows the mouse sort of. I know the explanation isn't very good so here is some code so you can see for your self: pastebin.Apologies for this bad quality (please point out the bad stuff so I can correct), but this is really giving me a nightmare and I couldn't figure out a clean way to write this.To clear the code up a little, the moving takes place where the selected handle is "m".[code]

Form Resize With Control Sizing?

Dec 27, 2010

I have been searching for code and/or a tutorial on how to proportianally resize controls and fonts. For example if I design a form at 800 X 600 and the user maximizes the form to 1600 X 1200, I need the form and controls to grow to fill the screen almost like a zoom function.

Form Resize With Control Sizing (con't) + 1 More Thing?

Apr 7, 2012

why the title has "(con't)" is because of this Form Resize With Control Sizing... almost named it with another thread on here. And I wanted to post, but it was already a 'Zombie Thread'.Thanks to _HAWK_'s post #11, instead of declaring every control I use. Would declaring it an array (fast guess - Label<Array(how many - 1; aka - X)>) work? ... that was probably Java... My point has probably been made, or can I just do Label.Scale(variable)?I had already set my declaration of the form I need to do this on "Resize". I am not quite at this stage yet, but I see this saving a lot of time asking early.

The +1 extra question is:How can I be able to split of a form in 3 unequal sections? The initial form is 800*600-left side has 2 sections, each 400*300 right side is 400*600.I am already using 3 'GroupBox' and it looks ugly because I have each one colored differently.I looked into Splitter and SplitContainter and TableLayoutContainer.

I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.

Access User Control Attributes From A User Control?

Mar 27, 2009

I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.

Forcing Re-sizing To Be An Odd Multiple Of 8?

Sep 11, 2011

I have a couple of split panels nested inside of each other. The problem is, I'm rendering an 8x8 tiled game inside of the center panel. Basically, the height and width of the panel need to be an odd multiples of 8 so I can find the center tile displayed easily.I need the width and height to be divisible by 8. The number 8 is multiplied by should be odd:EDIT AGAIN these numbers below do not refer to the size. They refer to two number being multiplied. I've changed them to a * to show this. These numbers below apply to both the height and width. One number should be odd, the other 8. 8*x

5*8 - Good
6*8 - Bad

Sizing Image To Fit Screen?

Oct 27, 2010

Having many thousands of pictures, I made a screen saver with the functionality I want. If the LAN path goes away it reconnects later, bad pics can be deleted, rotated and saved, etc. Sometimes the pics don't size correctly and expand off the screen. The problem may be reuse of the same picturebox. What I might do is have a dedicated picture box with autosize left on, use that to obtain raw image size, then reload again into the picture box that will be displayed.

Private Function loadimage(ByVal pic As PictureBox, ByVal lab As Label, ByVal fname$) As Boolean
With pic
.SuspendLayout()

Sizing The Listview Columns?

Jun 14, 2010

I've setup a listview with two columns. Both have a fixed width which totals the width of the control (to fill the control fully and not display a horizontal bar)This works fine as long as the form does not change, anything such as a font change on the system will cause the list view to look off alignment.LV2.jpg shows it in the designer, LV.jpg shows the same listview with a different font.Is there an easy method to fix the position or auto size the last column to the edge of the control?

Auto-fill A User Input Control With The User's Windows?

Feb 11, 2011

I am creating a form for work where managers can report when they find a customer's personal information laying around on a desk (we work at a call center where agents answer calls for a wireless cell phone provider, so we take personal information security very seriously). Anyway, I am wondering if there is a way to have a text box autofill with that manager's windows username (since they will need to be logged into their own profile to use the form).

Auto-sizing Buttons In TableLayoutPanel

I have a form with a TableLayoutPanel with the following properties changed from default:

This is a stripped-to-the-basics version of part of my app. I want to generate a vertical, scrollable array of buttons which will allow me to select groups of photos. Each button will represent a group of one or more photos in a collection. The app will scan a folder and determine which groups are present, and which files are in each group. I create the buttons (with AutoSize), then determine the width of the widest button (at the same time, setting the button anchor property to make all buttons the same width. I then set the form to accomodate the width of the widest button.

VS 2010 - Dynamic Picture Box Sizing ?

Jan 31, 2011

I am successfully able to pull images into a picturebox in my program and manipulate them in a variety of ways. What i need to be able to do is the following.

1) Pull images into a picture box on my main form and dynamically resize either the picture box or the image so that the image doesnt lose its scale when it comes in

2) Have a method of pre-screening an image to be loaded before it comes in so that i can change its size without losing scale .. ex.

if my image is 1200x1200 i do not have that much room on my form so i would want to say something like

if getimagewidth()>600 then

me.picturebox.width = getimagewidth()/2

end if

Windows - Auto-sizing Zoom On An Image In .NET

Jul 16, 2009

I'm considering a personal learning project. Using .NET(preferably VB) I want to build a simple desktop app that's only function is to display comics, like CDisplay, but with more advanced navigation. I want to be able zoom in by clicking on certain areas of an image, individual panels for instance, and have the zoom area automatically snap to the panel and blow it up. The images are usually in a standard format like .jpeg, .png, etc..

Something like this is what I'm going for: [URL]

I'm not even sure what this is called? Image mapping? Tone mapping maybe? Is it possible to do this within .NET or would it require some kind of outside library? Code samples would be nice, but obviously this is pretty vague request.

Make Assembly FULLY Trusted - Use The Web Browser Control In User Control

Dec 19, 2009

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

VS 2010 Auto-sizing Form Based On Text Box?

Jan 23, 2012

I'm trying to create my own custom "inputbox" (can't think of VB.Net term for the VB6 input box).

Anyways, I'd like to have a label & a textbox on my form along with 2 buttons. I want to let the label to grow based on the text that is in it. I know it has an autosize feature to it, and guess I can use that, how do I limit the width so that once it hits that limit it goes to a new line so that if I have a message or a question to pose to the user, it doesn't get too wide. Kind of like MessageBox.Show.

It'll be Label at the top, textbox under that, and the two buttons under that. I'd like the textbox to move up/down based on the size of the label, and the buttons to do the same along with the window not becoming too wide.
