View 4 RepliesAdding Decimal Points To Strings?
Jun 15, 2011I am working on a program where specific strings are being read from a file and displayed in a listview. Some of the strings represent money values though the file has no decimal points. I would like to add a decimal point before the last 2 digits of prices, quantities, and freights when displayed in the listview (not add two decimal places but actually insert the decimal point into the string). I would like to be able to keep most of the code I already have though, and I have no clue how to accomplish this. Here is the code I am using to fill the listview:

How To Make That Clear To The Users With Adding Some Points
Feb 5, 2011look at this picture of my index form. It's resized, now you can't see the full labels text.
Example: under the first cover, there stands "Hardbass Chapter" and accetly it is "Hardbass Chapter
21 (2011)". It's not a problem that a peace cut off, but, I want to make that clear to the users,

MSChart Spline Graph - Lines Are Choppy And Not Smooth After Adding Points?
Oct 18, 2011I am adding data points to a MSChart spline type graph, and the graph that is displayed after I am finished adding the data points is very choppy and not like a proper spline curved graph. It's more step-like than flowing. if I manually add data points to each series I can create a very smooth and flowing spline type graph. Here is the code that I am using to add the points:
For c As Integer = 0 To count - 1
Chart1.Series(0).Points.AddXY(c, Array1(c))
[code]....
Is there a step that I am missing or a parameter that needs to be set for the spline type graphs for this issue not to occur?
Adding A Point Overlayed Over A Specific Photo
Sep 8, 2009I've searched the forums for this, but I can't seem to find exactly what I am looking for. I have a form currently that allows me to open a photo in a picturebox. I would like to add functionality that would allow the user to click on a specific part of the photo and add a point overlaid on the photo. This point would be the graphical representation of comment that they will enter in a separate text box. I am stumped on how to even start to get this done.

View 2 RepliesVS 2008 Calculate Points On Line?
Feb 23, 2012Using the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.

View 1 RepliesVS 2008 How To Calc Curve Points
Jul 26, 2010The picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.
VS 2010 : Search For Text Within A String (Starting Point And Ending Point)?
Dec 31, 2010I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

VS 2008 : Microsecond Timer To Plot Points On Line?
Feb 27, 2012A couple of options seem to be available to achieve better accuracy and shorter periods than the Timer control in VB allows, however they too seem to have their own unique drawbacks. I am trying to plot (draw) points that are calculated in my VB application and then represent them in real time with an accuracy of a couple percent. If VB can calculate the points in the microsecond time range, would it be reasonable to hang an external pulse source on a usb port and use the "Datachanged" event to count the pulses that will be summed and used to plot the points?Ultimately, this is a machine control application that requires "reasonably precise" timing - ie. CNC type control. The points are scaled and drawn and then step and direction signals are sent out through another USB port.

Calculating Point-to-point Directions On A 2-D Grid?
Mar 11, 2012I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize

View 1 RepliesMove From Point A To Point B Along An Angle?
Mar 14, 2009I need to move an ellipse from a known point on the screen to another known point on the screen.
I've tried using For.....Loops with less than desired results.
I can't remember everything I've tried, a lot of trial and error has been layed to waste. Lol
I've ended up with this code after putting together what I've tried, what I've learned elsewhere, and a couple of posts I've read on here.
All I want to do is move the ellipse from one point to the other along a straight line that forms the angle between the two points (X1,Y1) and (X2,Y2), make it grow from 2 pixels at it's start, to about 80 pixels by the time it reaches half way, then shrink from 80 pixels back down to 2 pixels by the time it reaches the point (X2,Y2).
Easier said than done.
Here's what I have at the present.....
Dim W As Integer
Dim H As Integer
Dim Num As Integer

....This seems like such a simple task, yet it's been a week since I came up with the idea, and I've had little success.
