C# - Move A Rectangle Around A Canvas?

Sep 4, 2010

I have a canvas in the middle of my application with controls around it. I have a socket that recieves Points and saves them in a list.

I draw small 4x4 rectangles on the canvas for the number of points in my list.. say theres 4 points.. theres 4 rectangles.

I want to be able to move the rectangles when the points change with code.
is this possible without storyboards or any 'animation' class?

I have tried:

'cMap.Children.Remove(r)
'Dim nr As Rectangle = New Rectangle() With {.Width = 4, .Height = 4, .Name = "r" & P.Name, .Fill = Brushes.Red}

PictureBox Paint Event (With GDI Rectangle)?

Jul 23, 2007

correct way to draw rectangles onto a picturebox, and also to explain the paint event more clearly.Basically I have an application where a picturebox contains an image, this image is a small computer monitor as such:

The idea of this part of my application is that the user can draw small window size rectangles which represent windows later on. I have already used some excellent code on this forum to be able to draw the rectangles on the picturebox (As pictured above), the rectangle outline is drawn from MouseDown and MouseUp respectivley.

The problem I am encountering is with the 'repainting' of this rectangle. I have included code to repaint the rectangle in the Paint event of the picturebox. This works when you move the picturebox 'off screen' and bring it back. However when the form is re-sized or other various things occur the rectangle is not re-drawn? even though the picturebox 'appears' to be clean and always there!

My code is below, it is not full and complete, but the few main subs listed should give an indication as to how I am currently creating the rectangle:

Private Sub picboxAdvDisplay_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles picboxAdvDisplay.MouseDown
'Set the flag for Drawing enabled

[code]....

1. What is the CORRECT way to draw a rectangle onto a Picturebox?

2. How do you code so that the rectangle is ALWAYS visible/drawn on a form re-size, minimise, window overlap etc etc.

Draw A Rectangle In Picturebox In The Mousemove Event In Application?

Feb 14, 2012

Actually I'm creating a simple paint application in VB.Net 2010. I want to draw shapes in my application same as we do in Microsoft Paint using mouse.

I'm a bit successful also using mousedown and mouseup events of a picture box. The mousedown event sets the starting point and mouseup event sets the ending point(diagonally opposite point of rectangle.) The problem is "Nothing seems to be occuring between mousedown and mouseup events(Well..that is obvious because I didn't add any code on mousemove event). My question is: "Can I do something to see a growing rectangle during mousemove event?". The rest of the drawing should remain unaffected.

Identify Subtriangle Within A Rectangle Given A Coordinate In That Rectangle?

Feb 22, 2010

Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.

i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.

I think this would be something like >= the formula of the red line and >= the formula of the green line?

I'd like to implement this in VB.NET

Drawing Rectangle Inside Another Rectangle?

Jul 26, 2009

I'M creating a kind of photo viewer, and I cannot figure out how to orient the scroll buttons with the photos I want to draw because they all are different sizes.This is really hard to explain so please ask questions if you don't understand.I'M thinking if i could draw every photo on a single rectangle and then the scroll bars will position that rectangle up or down. but is there a way to make a rectangle inside another one so it only shows inside that rectangle?

VS 2008 Picture Box Mouse Move Event

May 25, 2011

In my project's Main form I have a picture box of size 1024*1024 which occupies almost 75% of my monitor screen. Now I have defined Picture box Mouse movement event with corresponding actions to be done for mouse mouse event over picture box. Now the problem is I have another button on my main form by pressing which an another form of size 520*170 pops up. I have set Me.Topmost property to this form. But even then if by I hover the mouse over picture box, this pop up form disappears (i.e. goes to back screen) and if at all i have to perform any action on this form I need click the Tab of the popped window on the task bar which makes this form visible. Worst case is if the user drags this form on top of the picture box and looses focus, then its impossible to get it(focus) back.

C# - Detecting The Form Move Event From Within A Child Control?

Jul 8, 2010

I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things

Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time

Here is some code

Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown

[Code].....

Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.

Does anyone have a trick to catch when the mouse is over a listview column header ? As you know there is no native handler that would fire such event...

I have build a small routine that will be able to tell over which column the mouse actually is, the problem remains in which event to put it..

Mouse-move Event Handler For Portion Of A Form?

Apr 16, 2011

I have a Windows form in VS2010 with a rectangular area that I draw in with Graphics.DrawImage for best performance. I want to create a Mouse-move event handler just for that area (to change the cursor when the mouse is inside it), along the lines of handlers for the other controls on the form. But since the rectangle isn't a PictureBox or Panel or other control, I don't see an obvious way to handle it. A mouse-move event handler for the entire form could affect the performance of the app.

Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

Jul 31, 2010

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

Heres the tutorial with my new code encased in asterisks ...

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?

Jul 20, 2010

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).

I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

myObject.rect.X = 100

myObject has a property called rect (which is a Rectangle). During runtime I will want to chage the X position of such rectangle, but I am given this error:

Expression is a value and therefore cannot be the target of an assignment.

Then, how am I supposed to change such values?
