Numeric And Non Numeric Data?
Jan 22, 2010I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.

VS 2008 - Storing / Using Numeric Data
Oct 20, 2009I have the book "Visual Basic 2008 Step by Step", I am in the final chapters and have completed all of the walk through and demo programs thus far. I am a beginner but I also have a basic understanding of quite a few program statements and objects. My Goal: For the sake of simplicity I will use an example. I have a Tetris game, the player loses in the first level earns 25 points they click the save score button. , they play again tomorrow and do 1,000 levels and earn 25,000, now their score is 25,025.
Then they play my blackjack game, they gain 25,025 points when they start automatically from their Tetris game, they earn 25 points in blackjack click a save score button, now they have 25,050. [Thus far I have 2 games, and they both share a score that will need to be added to in the future]

Bound Datagridview Sorting With Numeric Data
Jun 28, 2009I am a programmer from Uruguay. I have read the other similar questions about my problem, but nobody has given the answer I need. I use VB .net 2005 and its datagridview. I bind it to a dataset which is populated with a table of MySql. And when I sort the numeric columns, it sorts them as string, not numbers. I have tried casting the data to integer in the sql statement, but it doesn`t work. I changed the format of the column of the datagridview to single or long but it didn't worked either. I really can't believe it is happening, it is a so common need! I thingk It should be totally automatic.

View 5 RepliesReading Name And Numeric Data From Text File
Apr 27, 2012I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.
VB6 Adding Random Numbers To Numeric Data
Apr 5, 2010I have an issue in VB6 that is giving me a major headache. When using a variable defined as a single data type, VB6 will add random numbers to the number i assign to it.
For instance I have a single variable that is manually set to 0.3. Then i create another single variable and set it to 0.25. I have the program add 0.01 to the second variable until it equals the first. But they never equal. I couldn't figure out why when both were showing they equaled 0.3.

View 8 RepliesRead Binary File Containing Strings And Numeric Data?
Sep 5, 2009I'm having problem reading Binary file that has two types of data in it; Strings and numeric data in decimal format.[code]...
1. The loop doesn't stop, and it gives me "Unable to read beyond the end of the stream" Error..
2. The output isn't accurate, apart from a few random correct strings and numbers..
3. After the loop is fixed, how can i save the data to an Array or write it to a text file?. Can the be saved line by line so that the output file has the same number of lines?

Feb 27, 2009I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
