View 1 RepliesI 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.
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.
View 1 RepliesI 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 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 was wondering if there is an addon, or position controls for my website. I hate having to code the location of a button for example.
Isn't there a way to just move it freely around the form as you do in Visual basic or C# for example?
I have a form where I need to place some labels dinamically. Some of the label's height needs to change depending on the string size that will populate the label's text. So what I need to do is position the labels one below the other, after the text has been populated and the height has been set.

View 2 RepliesI have a system that has a collection of picture boxes.Each picture box allows you to place pointers(Custom control derived from label) on the image, when saved I store the X/Y for the pointers along with other information relevant to the pointers in a database.(See attached image)This way the chart can be reloaded and the pointers be moved or edited.This all works great until I resize a chart, the calculated percentage of size in/decrease often results in a float like in the following example. [code] I position the pointers by top and left, which only accepts integer, the rounding results in significant drift over multiple resizes.

View 4 RepliesI'm trying to position a small form that will have its top left edge exactly lined up with the bottom left edge of a label. But I am finding this to be impossible to accomplish because of some magical hidden offset that exists somewhere ... I don't know where.
So here's what I got, if I can manage to pilfer out only the relative portions... For the sake of simplicity, I'll focus only on the horizontal positioning below:
Dim FrameSize As Size
Dim TargetHorzFramePos as Single

I have a series of tabs, each containing a series programatically generated PictureBoxes that are all 480x360. The TabControl is anchored to all 4 edges of the form, so it always takes up the whole area.
I would like the PictureBoxes to behave similarly to how images behave when floated in HTML/CSS. So if I have 5 pictures and the window is only ~900 wide then I will have 3 rows, 2 in the first 2 and 1 in the last. But if the window is then expanded to ~1500 then I get 2 rows - 3 on the first and 2 on the last.
What is the simplest way to achieve this? Is there a built in way?I am planning on repositioning the pictures when SizeChanged fires on the TabControl, or when the selected tab changes.
