I need to create an application that creates Pascal's triangle the user would enter the number of rows, and using the formula (which i do not know... :/) would create the triangle. For example: the user enters 5 rows
triangle:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
as you can see the numbers are created by adding the 2 numbers above it starting with 1 at the top
I've done many attempts but still didn't succeed in making a logic for pascal's triangle, I want you guys to get me start this task and I'll code it myself. url....

I have created an shareware application using vb.net visual studio 2008 for windows desktop, and packaged it using innosetup 5.3.8. The problem is when i have installed the application in C:Program FilesApplication and it runs successfully(use trial period of the application), Im also able to install the application once again freshly with the same setup by installing in different directory.eg C:Program FilesApplication new . The application in C:Program FilesApplication new does not have any settings of the already installed one.
Where do i went wrong . Do i need to take care of this in my application(vb.net) or innosetup. How to take care of the already installed path in innosetup or carry the settings of already installed application to newly installed path by upgrading the older one.
I dont want to write any thing in registry because the application does not want any administrative permission requirements.If i install the application in same path it gets updated with the older settings being taken over to this new one and it works fine.
I was thinking about creating a program that creates an .exe file. (I know that that is very difficult but I have 3 days that I'm not sleeping because i'm thinkin about it)The program should create the .exe file on button clickThe created exe should be in Normal Windows State, it should have only a button that doesn't do anything and it's path should be C:UsersAdministratorDesktop

View 3 RepliesI am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I'm creating a movable scenary with, like 100 different flights. I want to create for every type of flight a triangle...so it's moves around and you have an idea how the airspace looksq like at what moment.Now my question is, what's the best way to draw these rectangles? I created a class 'Flight' and it has a Graphicspath in it. Now I want to update the triangle, which represents the aircraft, with the speed and heading...so it moves around well.

How do I draw a triangle?
View 10 RepliesCurrently working on a 2D engine, not for gaming but for design software / visualisation for machines. So far it is comming along quite fine. I started to wonder if it were possible to draw a triangle and fill it with some form of a a texture, or even better a polygon and fill that with a texture.
I know that DX can do that for me :P but I am realy focussing on GDI+ at the moment.

View 4 Repliesi was asked to do a program which can find if a 2d point is inside a triangle or not, only the 3 points of the triangle were given. i planned to do this using the slopes of the 3 sides, then with y-y1=m(x-x1) using the other vertex and the point being checked see if the slope was the same sign and on the same side of the line. if this was true for all 3 then the point is inside the triangle the problem is i cant think of a logical expression for the if/then/else structure to show this anyone know what i should use or should i just go down a completely different route?

View 2 RepliesI am working with a structure for a triangle.
Here is the code:
Public Structure Triangle
Shared a As Double = 1
Shared b As Double = 1
Shared c As Double = Triangle.FindC
Public angleABC As Double
[Code] .....
I am receiving an error in the function. "Triangle.angleABC" is generating :"Reference to a non-shared member requires an object reference". I need to find the hypotenuse for this Triangle. I have tried setting the variable as an object, this does nothing for the error. Also I've tried to use Public in the function and I receive an error stating it needs to be shared. I would like to work the the Structure with out running any functions on it first.
