VS 2010 Vector Graphics Code?
May 5, 2011
I need to write a simple program that imports tab delimited x,y coordinates into a simple form, by clicking an "Import" button and navigating to the particular .txt file. On the button press I want to read the text file and display these in the shape of anything from a simple square to a slightly more complex closed polygon (maybe using a path function) in the main picture box to view the shape.
Then I would like to press an "Export" button and save the displayed shape coordinates/vertices back to a file location of my choice as a .txt file.

I tried to make a menu for my game, but when I placed the code into the form loading event, it wouldn't show. Then I placed a button and moved the code into the button click event and it worked. Thus, I know the code shouldn't be wrong. How can you make the graphics( as in lines, rectangle,etc) show up when it starts up?

I have found how to create a metafile using graphics but I can't save it to a vector file. I tried the Metafile.Save("*.emf") function but when I insert the image into PPT, it appear to be a bitmap when I enlarge it.
Here are the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Using gRef As Graphics = Me.CreateGraphics
Dim hdc = gRef.GetHdc()

Is it possible to insert vector images (ecw or ai) in an VB.NET application? If so...is it possible to zoom in on them and keep the same precision? I'm trying to create a very basic GIS system and I need to zoom in on some places.

suppose i have a tree that have a root node. that root node have 3 child nodes. each child node have 3 child nodes and so on say up to level 4. if i number each node from the root node and numbering from left to right, the root node being number 1 and the left child of the root being number 2, the middle child of the root being number 3 and the right being number 3. on the third level the left child node of the left child node of the root being number 5 and so on. if i have numbers 1 up to 13 and want to put each number into a node numbered the same i.e number 1 gets into the root node, number 2 gets into the left child node of the root and so on. how would i achieve that.

I have a program in C++, that is doing some calculations. I use a vector in C++ and resize the vector in the program, in order to conserve and allocate memory. Can you allocate memory in vb.net? So if my user inputs 1000, I want an array/vector to have a size of 1000. Can I change the size of the vector in the program? And is there a difference between container types in vb.net, I was just assuming
Dim xx(1 to 1000) as double, is the standard way of declaring.
And resize xx(1 to N) would be the way to resize.
I am using visual studio 2008 express.

I am working on a project where my forms resize to fill the users screen (which means they have different dimensions depending on screen resolution).I have made some vector images (.eps) in hopes of using them on my forms so that when the form opens the images always look clear, crisp, and not skewed.I am finding that vb.net will not let me import a .eps file into my resources. Is there a way around this? Is there another way to get a vector image into vb? possibly an SDK that will allow me to work with .eps files the same way i work with .dcm images?

I am looking for tools that will enable me to search and manipulate pdf files and pdf vector graphics. I want to search a pdf image/file for specific content and then manipulate the image. Are there any known resources out there? I have looked at the documentation on the Adobe web site, but I don't know where to begin. I'm looking for books or a forum where I can get specific information and examples.

I've been trying to get some help for this in another thread,but it looks like it's a task that is going to need a wider audience to try and find someone who knows something about writing/creating procedural textures at the pixel level in VB.Net. The VB6 example I'm trying to convert to VB.Net is attached to this post.

Is there an easy way to display the rgb code of system colors in VB2008?
That is, I am looking for some code that will retrieve the names of the colors that are used in the system colors and display their rgb codes (and maybe show a sample), so I could display, for example, what the rgb code for "control" is.

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases. After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
[code]...
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
[code]...
But although this works, it does not execute my VB code in the code behind page so I am a little confused where to go here.

I've rendered a simple rectangle for the background and a bunch of star polygons randomly placed across the form. On the form is a picturebox component which I can move around, but for some reason it overwrites the background and stars when it passes over them. Could someone please explain what is going on there? I've tried performing searches, but have been unsuccessful in finding anything useful.

I am pretty sure that my questions will soon get so annoying you won't answer them, but before it happens.I am using DrawCurve (with density set to default) to draw on my picturebox. I need to know the exact length (well, not *exact* but knowing it is around +/- 1px from exact length would be nice) of the curve drawn.
Is there any function in API I could use to get what I want? If not, could you point me to the algorithm (preferably implemented in any language) that I could use with array of points as an input and length as an output value?

For some reason I could never get over the look of my application, and the Microsoft controls together. Just never looked right. Nor were the controls exactly what I needed. By creating controls I can pretty much custom fit them for my application, and I love it.My question is with drawing these controls. I have 12 of them now in my current project, so I would like to make them all as efficient as possible. The biggest set back to most of them is the drawing can be a little extensive, or at least to a point where they could be more efficient. At the moment, under each paint event I have the brushes created by using blocks and then the drawing happens within them(I create all brushes first, then do the drawing, vice versa with disposing them). My question however came up when I was creating my most recent control, a SimpleList.
I experimented to see(though I'm not sure how exactly to track performance) but instead of recreating the brushes and pens etc in the paint event, I put them at the top so they're only made once, and destroyed once, rather being made and destroyed every time my control paints. My common sense tells me this is a better way of going about this but my experience can't back that up. is this the way I should be going about user drawn controls?, is there any limitations to this?(like would it be okay if I only had a limited number of brushes etc) and is the performance even that greatly impacted by making these changes that it's worth my while?
