In the past, in C and C++ land, nested pointer dereferencing was considered, by some, to be a relatively expensive operation if executed in a tight loop.You wouldn't want to get caught with:
for (int i = 0; i < 10000000; i++)
{
j->k->l->m->n->o->p->dosomeworknowthatwereherewhynoteh();
}
because you might lose precious milliseconds. (Yes, I'm being somewhat sarcastic!)

Convert decimal value to feet inches?

The panel is not displaying at the correct size. It is too large.

View 1 RepliesIf you add a list view, then add a column, and an item, set the view to Details and run it, there will be dots around the item. Those dots will also appear whenever you select an item, along with a highlighted color. I've downloaded projects that don't have them, and when comparing I don't see any difference in listview settings between that and my listview... How do you remove those dots?

I am using a software that grasp information from web-sites. But I want to something on those information. For doing that, it allows me make a VB script. Actually I have never studied any Vb code. But i found a solution for my project. The data from that website is for exmp. "1.02.30" I want to change first dot into semi colon and the second dot into comma, namely "1:20,30". I found replace function and it works if i want to do "1:20:30" that. But I have to change first dot into semi colon and the second dot into comma.
View 3 RepliesI am attempting to make a unit converter that converts between km, m, cm, miles, yards, feet, and inches. I have a textbox that is used to input the value to convert followed by a space and the units (i.e., 56 km) and a second textbox where the user types what unit they want to convert to (i.e., cm). When converting, the output will be displayed in the second textbox. (I know this is complicated, but this is the way it is to be done). I am doing this using sub and function procedures and If blocks and Select Case blocks (i.e., keeping it as simple as possible).

I know that you can return the length of a string, which results in the number of characters and spaces. Is there a way to return a width of the string in say, pixels,inches or some unit of measurement.
View 8 RepliesPicture 1 shows an application that I am currently writing that uses the LineShape and OvalShape out of the Visual Basic Power Packs. As I change the index in the part number combo box the A, B & C dimension change to suit the dimension in the text boxes.
Problem is the limited shapes are fine to draw a router template guide, but they are somewhat limited when it comes to drawing more complex shapes like the router bits that make the shapes in Picture 2. Is there a graphic class that would allow me to plot points and joint the dots like you get in kids colouring in books? Or something a little more adept to complex shapes like curves?
I just spotted something called the Pen Class that I might need to look more into, but not knowing the first thing about graphics. Spotted some advice passel gave in another thread to search vb.net gdi+ tutorial and it looks like the Pen Class might have potential, although I am going to have to revisit some math by the looks of things.

View 4 RepliesI have a problem drawing dotted path lines, with evenly spaced dots: I want to be able to draw evenly spaced dots along a path line using points in an array, My issue is not with drawing the path line, with dotted lines, this is easy, but with the spacing of the dots at the start and end of the path line.
In the example I have created, I create a square with 4 points and draw a dotted path.The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have.I have also attached two pictures showing the dotted path line, 1 with even spaced dots at the start / End and another showing the problem I want to resolve, with not evenly spaced dots at the start / end.The only difference between the two is the point values.
What I need to do is find a string that can be any value, and is placed between ">" and "</" with a minimun length of 5 and a maximum length of 7 and contains exactly 2 dots.
So if I have a text file like this:

I want it to find only the 5.0.77. And no, the number isn't always between h2 tags, and the number isn't even always the same. The only thing that is static about it is that is is between ">" and "</" and that it is between 5 and 7 characters and contains 2 dots.

If it should be posted in another place (even on another board) For some given curves (see sample below) I have to quantify whether the red dots in some regions of the curve are more dense at the upper or lower edge of the curve. Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.)

View 4 RepliesI have a problem. Im trying to create a form that enables a user to add dots on a mouse click event over an office floor plan. I have searched the web and this site but still am struggerling. My aim is to be able to draw dots (purpose is to highlight problems) and polygons over the plan (purpose to define which service area the floor area relates). I want to save all graphics to an access database with associated
fields.
My thinking is to place a second picture box over the first and make this transparent and use this as the user interface? I dont expect anyone to solve this for me, however, any help with how to draw dots and polygons through mouse down or mouse click would be most helpful.
This is a followup to this thread, where I'm trying to draw two sets of dots using HatchBrushes to create VS2010-like interface. If you take a look at the zoomed image of the IDE background (blue with dark and light blue dots): that is what I'm trying to draw using GDI+. In the previous thread ForumAccount find the correct HashStyle to use (Percent20), but there is a problem: I need to draw two sets of these hatchstyles: once with a slightly darker color and once with a slightly lighter color, at an offset of one pixel downwards.
