Our VB.NET project is using a Java library from Vivid Solutoins [URL}... to do Geometry calculations.[URL}...
What I can't figure out are the units specifically for the Buffer property, or any other distance for that matter. My program is dealing with Nautical Miles, and the documentation gives no indication if the units are degrees, miles, Nautical Miles, Kilometers, inches, etc.
I'm trying to write a little program to help me find the distance (in feet/inches) between the frames of a ship. This would be fairly easy, except the frames are unevenly spaced.Let's say this is a top view of a shape, and the frames are vertical lines that comprise the overall ship. (In ships, this is the shape of the hull.) Each number is a frame.
1 2 3 4 5 6 7 8 9 10 11 12 13
In this example, there are 1 units between frames 1-3, two units between frames 3-6, three units between 6-9, four units between 9-11, and 1 unit between 11-13.So, what I want to do is post a program where the user inputs two frame numbers: so they would enter, for instance, a start location of 5 and an end location of 11. So, it would calculate the number of units between those two frames based on the limits. So, between 3-6 there are two units, so it would subtract the start location from the nearest limit (6).
6-5 = 1
Multiply by 2 units spacing per frame, so that's 2 units. Frames 6-9 are all included, so 9-6=3 x 3 units = 9 units. Since 9-11 are also all included, it would be 11 - 9 = 2 x 4 units = 8 units. Then the program would add that all together - 2 + 9 + 8 = 19 units total.
Now, for my instance, there are a few more complications (it's in inches, and large increments (i.e. 36" spacing), and there are 304 total frames split between the middle of the ship in two sections, fore and aft of the line), but really I'm just trying to get a handle on how to impose these limits and calculate the distance. Attached is the proposed layout for my program (ignore the 20'5", that's just how I want the output to look).
You could check to see if the distance across the form minus the distance across the picture box is equal to the horizontal location of the picture box to see if it's on the right side. For the left side, just check if the horizontal location of the picture box is 0.
View 2 RepliesI'm trying to make hit testing work between one user control and another user control. I was looking at other questions and found that I have to put this in my user control.
Protected Overrides Function HitTestCore(hitTestParameters As System.Windows.Media.PointHitTestParameters) As System.Windows.Media.HitTestResult
Return New PointHitTestResult(Me, hitTestParameters.HitPoint)
End Function
I also have a filter which correctly shows the controls I want to hit-test somehow the htcallback isn't working.
Because I can't hit-test with my user control, I made a rectangle on the same spot and use that in my hit test. This doesn't seem to be working.
Dim hitTestGeometry = New RectangleGeometry()
hitTestGeometry.Rect = New Rect(_selected.breedte, _selected.hoogte, Canvas.GetLeft(_selected), Canvas.GetTop(_selected))
[Code]....
if you want to hit-test against geometry you need to override that second overload as well
In order to call a java class in vb, I found the following procedure and I tried.
(1) create a java class (eg: MyTest .java)
as
public class MyTest
{ public int myfunction(int value1, int value2) { return value1+value2; }
(2) compile to get a MyTest.class
(3)register Mytest.class using javareg.exe file from Microsoft SDK for Java using javareg /register /class:MyTest /progid:MyTest and see a MessageBox displayed with Succesfull register Class message
(4) copy MyTest.class to C:WinntJavaTrustlib
(5) open a New Project on Visual Basic. And paste this brief code on the Form Load event for example and run it. Set x = CreateObject("MyTest") MsgBox x.myfunction(1, 1)
I did all the above steps but when I run the vb program (Step 5), I get the error message "Cannot create ActiveX component". Unhandled Exception message.
I am using Java 1.5 and Visual Studio 2008.
I have a class in java "Main.class", wrote and stored in %TEMP%. When executing the class through VB.Net Shell, eg:
Shell("cmd.exe /k java %TEMP%Main.class")
Also when trying to execute manually through CMD: "java %TEMP%Main.class", I am returned with:
Exception in thread "main" java.lang.NoClassDefFoundError: C:UsersBenAppData
LocalTempMain/class
Caused by: java.lang.ClassNotFoundException: C:UsersBenAppDataLocalTempMai

However, when I execute Main.class manually through compile.bat - the class runs fine. What is the reasoning for this?

View 1 RepliesI have been asked to create a project in vb.net which needs to integrate a java class created by Apple (Autoingestion.class) to pull sales records and so on.I found out a couple of questions here on stackoverflow but none of the answers given worked for me when trying to integrate this java class in my .net application.For example this question seemed to be what I really needed but when trying to compile this java class (I decompiled it first using Java Decompiler), it generally throws some errors.All I need is to use this class in my application to invoke a method.Does anyone know how to pull this out without much ninja-ing?
View 1 RepliesI wrote a Java class that parses a bpel text file and then returns a count of the number of occurences of certain words. I wanted to convert it to VB2008 Forms application, so that its results are displayed in a TextBox and not on the console. The problem is that VB2008 lacks Scanner and StringTokenizer classes, which are in my current Java class. Am not sure how to get the same functionality (or better) in VB2008. Can someone out there help to convert this class.

can i calculate the width of that triangle at 1/3 of the distance from the point + 2/3 of the distance from the point?

There doesn't appear to be any way to "setIntegrationMode" to a specific value.

View 1 RepliesSo i decided to make a units converter for my term's project and my teacher insisted on including the combo box in this project. I'm not really familiar with the combo box as i am still a beginner in visual basic. I've looked around and learned a bit about using the combo box but later i faced a problem. First i created a Main combo box and placed it in the middle of the form. I managed to use the select case command to make other combo boxes appear and disappear as i wish. I don't really know how to describe the problem, i want to make it that if i choose the input as a unit and the output is any other unit from two different combo boxes, the value in the input text box would be multiplied by a certain conversion factor and the result will be shown in the output text box
