I am just wondering how to encrypt my program so people can't hack it. I have a program that has a spot where you can type in problems with the program and it will email it to me. But, when I release my program people hack my email and password that is used to send the problems.
View 7 RepliesI want to make a program that will track Do Not Rent (DNR) People.I'm a intremediate vb6 programmer and have not coded in a long time.I do have and wanting to do this on VS2008 professional in VB2008.I did a simular program from a vb6 book about 12 years ago. it was a address book that i changed a little to add some things I needed it to keep track of, and it saved everything in a text file.I want to know what the pros and cons are for using a text file? xml file? or a data base?the data i be keeping track of will be vital statistics as name, state id number, id type, ect. and a picture of the id from a scanner or import from a .png, .jpg, or tiff image.If i use a data base file either Access 2007, MySQL, or SQL 2005/2008 file, do i need to have Office, MySQL, SQL 2005/2008 programs installed on the the computer im doing the programming on? do i need to have the above programs installed on the target computer?i do not think a txt file will work for me because of the picture i want to keep with the data not seperatly. So to make it a little more clear I want to be able to add, append/update, not to be able to delete a record, and be able to search the file for a record.I want to be able to navigate the records or file with first, previous, next, and last. each record will be showed seperatly.I would like to have a STATUS (lol thingy) that only my wife or I can change but let my employees be able to enter the rest of the information on there own. the STATUS Levels will be like 1st warning, 2nd warning, 3rd warning, DNR, and Rentable at our discression. I want it to only allow changes to status if they have the proper password. so i do not know if this also elimates txt files or xml files as an option.and when the wife, my employees or I make an entry I wanted it to add the time and date with the comments we entered in with the initials of the person whom entered the data. so i was thinking i will need to have security levels in my program and give each person a password so the program can fill out most small data itself.
if i do decide to use a database file to store the data, picture, and employee information can it be done with 1 table, or should i try to seperate the data in seperate tables? should i use one to one or one to many? I do not think one to many would be the best solution? it been like 12 years since I did any database programming in school and it was dBase3. If u think it be best to use multiple tables could u give me an example as to how to seperate the data.The client info would be like a address book with a picture and a comment box that will automatically add a date/timestamp and the users initials with a space between every updated or appended entry., and the employees would have there login in name and password, and initials.I was thinking of making a wizard to enter the data in for both employees and the DNR's as for people changing the date on the computer and entering info so to make it look they entered data on an earlier date I was thinking of having it log onto the internet time server and setting the date/time of the computer in the background as it loads up.

I need to simply identify if a particular tag occurs in an XML document. At this point my XML solutions, much like my regex solutions, are based on limited knowledge and are far from elegant. Is there a better way to achieve the following:

I am trying to make a program that can calculate the percentage of people passing an exam. There are buttons for each letter grade, and working label counters for each time you press a button. Each button looks like this, except replace the letter with the appropriate one.
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblA.Text = intA
lblPercent.Text = (lblA.Text + lblB.Text + lblC.Text + lblD.Text) / (lblA.Text + lblB.Text + lblC.Text + lblD.Text + lblF.Text)
End Sub
My problem is that the percent does not equal what I get when I put the exact same numbers into a calculator.

View 1 RepliesI have a voice program that can compare voices to stored voice files and identify people based on that. It's not the most accurate thing, since being sick or other weird things can make it fail, but it does work for the most part. I was wondering if there was a way to keep the voice recognition running during an unlock and wait for the person who locked it to come back. Upon giving the command and voice verification, if it passes, the computer is unlocked by my program. Is there anyway to do this in VB.NET?Summary: Can a program unlock a computer after it's locked?
