Identify 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?
I'd like to implement this in VB.NET

View 10 RepliesDispose Managed Objects In 2008?
Jun 1, 2011In My application, I have an MDI form. From MDI form I open all forms as child forms. I have implemented IDisposable for all large objects like file stream DB connection etc. In the Form_Disposed event I dispose all unmanaged objects. After the child form is closed, all unmanaged objects are disposed but managed objects (controls and form) are not disposed and still in memory. I find it from .Net Memory Profiler ([URL]).
So I have write code to remove all event handlers of all controls and form. Now, When form closed, dispose is called and all event handlers and controls are disposed, but controls and form are still in memory.
VS 2008 Call Dispose On Brushes?
Sep 16, 2009In my Zeal to get with the "Dispose" program, I implement a dispose pattern (still learning the ways and means of THAT) wherever it seems to make sense.I THINK I have the basic idea. However, I notice that, while Drawing.Brushes HAVE a Dispose method, when I call it, some sort of instability is created in Visual Studio itself, and i get the dreaded "Visual Studio has encountered an error and needs to close" splash screen, with no useable error information. SHould I assume that one should just NOT call dispose on Brush objects, or is there something I am missing here: [code]

View 6 RepliesVS 2008 DataTable Clear Or Dispose?
Feb 18, 2010I want to understand a situation; it's related to datatable clear().I have a code that populate a typed datatable from Excel in a separate thread using a backgroundworker. This works well, the table is filled and I can see the data. Now, I want to clear the data from table and restart the import. The operation is ten times slower than the first time. My datatable variable is declared like this:Private dt as new DataTable - not a local variableI want that all subs from class to be able to use the table, that's the reason I declared the table as private. What I want is to be able to create a new instance of dt (or clear allocated memory) - maybe this is the reason for slowdown.
View 2 RepliesVS 2008 Form Close Vs Dispose
May 6, 2009I am using VB.NET (Visual Studio 2008) and thus .Net framework 3.5. I have developed an application which has a MDI form and then has several other forms, most of which are shown using form.showdialog and some set of forms are shown using form.show. Whenenver a form (shown using form.showdialog) was closed (usually by clicking on a button (OK or Cancel)) I wrote code Me.dispose. After careful testing and R&D I figured this caused flickering on the screen. There use to be a flicker on the screen and it looked weird.

VS 2008 Text Clipping Itself Rather Than Exceeding Rectangle?
Apr 6, 2009I've drawing text to a rectangle, say for example "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789",That should be centered (which it is), but be on one line, not clipped like this:
"ABCDEFGHIJKLMNOPQR
STUVWXYZ123456789"
my String Format is:
With sfFormat
.Alignment = StringAlignment.Center
.LineAlignment = StringAlignment.Center
.Trimming = StringTrimming.Character
.FormatFlags = StringFormatFlags.NoClip
End With
It doesn't even have to trim it, like I have in my code, but it won't even stay on one line.
VB 2008 Memory Leak - The Graphic Doesn't Dispose Properly And Garbage Collector Gets It?
Jul 7, 2011I have prided myself in having a pretty clean code however in the game I am making I have a player view (showscreen) and a host view, which is a copy of the player view (on a smaller screen). This way the host can see what's going on.The problem is that the graphic doesn't dispose properly and Garbage Collector gets it, though I have noticed it will crash if GC doesn't get it in time. The larger the showscreen window the more junk gets put into memory, which sucks.I thought I had everything correctly disposed below but still doesn't get the job done.

VS 2008 DrawString Long Text Inside A Rectangle
Mar 27, 2012I draw text (comment on item in an invoice ) inside a rectangle.

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.

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?
