View 9 RepliesI am writing my own script for a simple calculator that determines if a number is prime, and its prime factors.[code]The loopcount = compare - 2 means I want the loop to be 2 less than the square root of the answer so that when do a descending calculation (loopcount = loopcount - 1) it doesn't see if 1 or 0 is a factor of the answer. for the calculations after that, I want, every time n1 = n2 (a whole number factor of the answer), I want to report those results to a text file (n2 and n3) in this format "(n2, n3)" then go to the next line. and continue to execute the loop until the loopcount is zero. Currently, when I run the code, the application closes when I click the prime button (button that runs this code) and I don't know why. This is my first semester in school, and have never coded before, so I am a definite laymen with code, but I really really want to learn it (hence why for fun im just creating algorithms for different things).

View 1 RepliesI'm working on a project that incorporates an Arduino Duemilanove board and a program that a wrote in VB 2008. Basically, when the Arduino receives a symbol from COM3, it sets a Pin on the board, high or low. I'm using two Pins, one is going to be for a laser, the other a relay. The relay is going to close a circuit, and act as the button on the Nerf Vulcan. That's right, I'm creating a Nerf sentry gun.It's going to be fully controlled from my computer. I have all of the code done for the servo, and all of that, both on the Arduino and in VB.
The Arduino sends the angle of the Servo that will control the right and left movement of the gun through COM3, every time it changes. I want my program to display that position in a textbox, as my program needs that value in order to properly function. Basically, I need the code to read from the serial port, and display what it receives in a textbox, textbox3.

I finished a course on VB in school. Now, I know how to read in a file, but I'm only used to plain text files. The file type I wish to use is called .pkm. It is a pokemon file type (yes, pokemon, don't make judge). Anyways, it's basically a file full of hex values that the game reads to display a pokemon. A friend of mine made a program that displays the hex from this file. He used Delphi so I'm not really sure about it in VB.

View 9 RepliesIve figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.

A VS 2008 desktop .NET program needs to open a PDF file and read its contents as data. That is, the program must scan through the PDF file searching for certain text. The program will not merely open the PDF file and display the contents using a control such as an ADOBE Reader control. It has to actually read the individual data within the PDF.
How can a .NET program read data within a PDF file?
