View 4 Replies[URL] In my Windows Form, I wanted the user to give an option to draw all over the form. But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.
View 3 RepliesA rectangle is painted in Sub pBox1_paint. My intent is to add data to pBox1 via 'drawstring' in Sub btnMoreThan30. The first line of Sub btnMoreThan30 originally included 'ByVal e As System.EventArgs'. The compiler flagged the phrase 'e.graphics' with the error:'Graphics' is not a member of 'System.EventArgs'. I then modified line 1 of this sub as it appears in the code below.

I've got a project where I want to be able to display a world map and draw lines between cities.I've looked at using a web browser with google maps but don't want it to have to be used while "online"
I've looked and longitude and latitude and converting these to UTM co-ordinates but i'm lost for how to place these on world map programaticly.I have a full list of all cities used in my program and have a list of their latitude and longitude co-ordinates because i need to work out thier distance apart which I have already done the code for.

Now, it draws perfectly when I drag left to down (vice versa), but when I try and drag the opposite way (this is when I get negative x and y values), it doesn't seem to draw the rectangle.I've tried fixing it but with no luck at all, it just messes it up :c

View 2 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

View 6 RepliesIn Visual Studio 10 - Visual Basic, why can't I import "System.Drawing" when my only reference is "System"? I can import "System.Runtime.InteropServices".To reproduce my problem:
1. Create a New Project in Visual Studio 10 with Visual Basic Class Library template.
2. Add "Imports System.Drawing" and "Imports System.Runtime.InteropServices" at the beginning.
3. Remove all references except "System" in the References pane of the project properties.
Result:Visual Studio cannot find "System.Drawing" but it can find "System.Runtime.InteropServices". "System.Drawing" is fully qualified so the system should be able to find it inside the referenced "System".
Thoughts:It appears "System" and "System.Drawing" are distinct namespaces (or containers?) so why doesn't qualification "." work? Does "." represent something else? "System" is also in "mscorlib" but is that the namespace which is used or is it another?"Microsoft.VisualBasic" is also listed in the imported namespaces but there is not a reference to it. How was it found? Where is the "Imported namespaces" list populated from?I have been looking through it for a while but cannot understand why "System.Drawing" is not imported.

View 10 RepliesI have made an application that can render and save a given element.

This works great except I have to specify which element I want, and I essentially want all of them. Is there some sort of for each that could iterate through all the possible elements?
(Edit: to clarify, my main goal is concurrency, but not necessarily for multi-core machines)
I'm fairly new to all concepts on concurrency, but I figured out I needed to have parallel drawing routines, for a number of reasons:
I wanted to draw different portions of a graphic separatedly (background refreshed less often than foreground, kept on a buffer). I wanted control about priority (More priority to UI responsiveness than drawing a complex graph). I wanted to have per-frame drawing calculations multithreaded. I wanted to offer cancelling for complex on-buffer drawing routines.
However, being such a beginner, my code soon looked like a mess and refactoring or bug-fixing became so awkward that I decided I need to play more with it before doing anything serious.
So, I'd like to know how to make clean, easy to mantain .NET multithreaded code that makes sense when I look at it after waking up the next day. The bigest issue I had was structuring the application so all parts talk to each other in a smart (as opposed to awkward and hacky) way.
I have a preference for sources that I can digest in my free time (e.g., not a 500+ pages treatise on concurrency) and for C#/VB.NET, up to the latest version (since I see there have been advances). Basically I want something straight to the point so I can get started by playing with the concepts on my toy projects.
