Jul 26, 2009I'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?

Parameter Is Not Valid Error While Drawing A Rectangle
Jun 26, 2011I have made a program that lets you select an area of a picture and then crop it, I am having problems while drawing the rectangle that shows which area will be cropped, following is my code.
[CODE].............
This is declaration of all the variables that I am using.
[CODE].............
Over here I send the graphics handle of the "canvas" control (which is just a picturebox) to a higher level, so I can use it later.
[CODE].............
Over here I get the starting position for my rectangle
[CODE].............
This part is supposed to draw the rectangle, as I am moving the mouse over the Canvas control, but I get an error where the rectangle is being drawn, I originally thought that the problem might have been with the fact that as soon as I begin moving the mouse, the CropWidth and CropHeight variables are at zero, and that is causing the invalid input error. So I made it that it would not draw the rectangle until it reached a minimum size of 4 x 4 pixels but it still does not fix the error, I debugged to see if there was a problem with the values of the variables, but they all seemed fine, I even tries doing this CanvasGraphics.DrawRectangle(Pens.Red, 20, 20, 20, 20) so as to eliminate the factor of the wrong values, but still the same error.
Drawing A Resizable Rectangle (by Edge/corner Dragging)?
Jul 19, 2003I am trying to make a rectangle that can be resized by the userby clicking and dragging the edges/corners of the rectangleTypically, if the mouse enters the rectangle region, then smalladjustment boxes should appear at the corners of the rectangleand also at the middle of the rectangle's edges (to allow the userto drag and resize the rectangle). When the mouse leaves therectangle region, then the adjustment boxes should disappear.I have the code to draw the rectangle and to produce the smalladjustment boxes, but I'm not sure how to accomplish thedrag and resizing steps (or if it's even possible with the way mycode is written).

View 3 RepliesVS 2008 - Drawing A Rectangle Snapped To A Grid By Getting Start Point
Dec 27, 2009I'm drawing a rectangle snapped to a grid by getting the start point(Mouse down e.location) and the end point(mouseup(e.location). The coding I'm having trouble with is having the program determine which way to draw the rectangle(where the location should be, and the height and width.) Now, this would be extremely simple if the user started their rectangle from the top left corner and ended it in the bottom right every time. But you need to be able to drag from all angles. So does anyone have some code lying around that I could look at so I could actually get my rectangles drawn right?

Mar 27, 2012I draw text (comment on item in an invoice ) inside a rectangle.
[Code]...
I have no problem, the text appear on several lines and it is well wrapped. But if the text is too long to be drawn inside the rectangle, I need to draw the text not drawn in another rectangle (on another page). How can I know the text not drawn in the first rectangle ? I think it is more difficult to use MeasureString because the text is wrapped.

Unfortunetly it is very difficult to draw nice images/drawings ect with the GDI+ engine. Is there any other way in doing this?

View 4 RepliesGetting A Label Inside A Picturebox During Runtime
Jan 3, 2012I'm trying to create a bunch of labels during runtime that will be "inside" a picture box, so when I move them, if their new coordinates are outside the box's dimensions they wont display, or if they're right on the edge of the box only half the label will be visible etc.
I thought label.Parent = picturebox would work but it doesn't seem to do anything, and Google keeps telling me to set the label's container to the picturebox - which sounds right, but maybe it's no longer a VB.NET thing since the Container property seems to be Read Only.

View 8 RepliesIdentify Subtriangle Within A Rectangle Given A Coordinate In That Rectangle?
Feb 22, 2010Given 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?

View 2 RepliesDock A Control Inside A Panel At Runtime On Windows Forms?
Jul 27, 2009I am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel
