1. I have updated the image based on feedback from Steven_W so there are 4 triangles in the right hand diagram instead of 3 which makes more sense!
2. update image again to label sub triangles as A, B, C, D in grey
What is the pseudo algorithm for mapping a coordinate (x,y) in the left hand square such that a coordinate (u,v) is produced within the rectangle bounding the triangle on the right so that points are interpolated between the mapping points as illustrated on the diagram? 1 to 4 are equidistant on the triangle from left to right even though my illustration is a bit rough around the edges :)This is to generate a rough and ready panel for the lid of a skybox from the top half a 360 degree panoramic photo.
update 3 based on feedback.The first step appears to be working out which triangle we are in for the left hand diagram based on the (x,y) coordinates.The second steep is to work out the distance along the vertices of that triangle. Then use those distances to get the coordinates on the related triangle in the diagram on the right
update 4 - code to identify triangle in left hand diagram

I'm making a hangman game right now, and the way it works is: It takes ten words from a text file and puts them in an array.It's supposed to take one of those words randomly and change all the letters to asterisks and display it in a text box for the user to start playing.I'm currently having trouble with converting the whole word into the right amount of asterisks to display.As you can see, I've already started trying something with a for next loop to go through the word and replace each letter with asterisks.But I'm not sure of the exact 'wording' of it.
View 1 RepliesI am having issues getting my application to display the correct number of asterisks per store. Also, I cannot figure out how to get each store to display in the list box.
' BarChart: Chapter 5 #6
' Program Discription: This application prompts the user to enter today's sales
' for five stores. The program then displays a bar graph comparing each store's
' sales. The bar graph is made up of asterisks in a list box. Each asterisk
' represents $100 in sales.

I have vb.net 2003. I have to output a pyramid of asterisks of six lines, 10 times (vertically). But the catch is that I have to use a loop. MsgBox("*" & vbCrLf & "* *" & vbCrLf & "* * *" & vbCrLf & "* * * *" & vbCrLf & "* * * * *" & vbCrLf & "* * * * * *") would give me one block of pyramid but how would I get a message box to display 10 of these at the same time? I'm pretty sure a nested loop would work but I've tried for hours and I can't get it to work.
It would look like this:
CODE:
After exporting data using a third party component the data in the excel sheet isn't type correctly. Excel thinks that some values are string while they are numbers and a little green triangle shows up.
We've coded the following to fix this:
For Each objCell As Microsoft.Office.Interop.Excel.Range In objWorkSheetReport.Range(objWorkSheetReport.Cells(1, 1), objWorkSheetReport.Cells(Me.RowCount + 10, Columns.Count + 10)).Cells
[Code].....
This removes all those little green triangles but is really slow.
Is there a faster way to convert a Range of data quickly so the green triangles don't show up?

I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.
View 5 RepliesIf e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.

View 20 RepliesI've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
Public Class Form1
Dim word
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

In class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic. Now my program doesn't recognize one of my forms when i try to access the design view of it. I hit run for the hell of it and the program runs with errors of course but the form1 "the missing one" shows up with all the buttons etc and i can use it.

View 9 RepliesThe program allows users to insert Documents along with a bunch of their attributes into the program. The documents are stored in a relational database. One of the required functionalities is allowing the user to look for such documents. The User normally search directly for the obvious attributes of the document, like a unique ID, or it's Title. The problem is that from the search parameters is not allways known which ones will the user fill. For example the user inserts the name and version of the deocument, another time the user enters part of the Title and the person that delivered the document, or might just enter the document number and nothing else. Some of the data might even be incomplete, like title, name of the person who created the document and so on. The idea from the person who designed the system (I'm only reimplementing it) was to allow easier searches for the user, and allowing the user to search for more parameters tod with the idea that "the more parameters, the more specific results", since the results are always group of documents instead of single documents.
View 14 RepliesI have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.
