Multiplying Without Using A Button?
Apr 9, 2011I'm new to vb and I am currently trying to code a Program for counting cash from a till. I know how to multiply and add if I were to use a button to execute it but what I want is for the totals to be automatically populated as soon as the user inputs the data.
Example:User inputs 23 into the txt1cent textbox
So the program should multiply 23 by 0.01 and output the answer (0.23) into txtsum1cent textbox.

View 6 RepliesMultiplying Odd Numbers In Sequence Using MOD Function?
Jul 2, 2010Then you have to take that same range and find the product of all odd numbers between said sequence. I figured out how to find the product but only if the lowest number is also an odd number. For example, if I put in the values 1 and 7 the product is 105 which is correct. But if I put in 2 and 5 the product somehow becomes 10, when it should be 15.I have to use the MOD function to distinguish between even and odd numbers, which I know how to do however it's still not working out correctly for some reason and I'm completely stuck. This is the part I'm having trouble with. Go down for full source)

I need to take the quantity * price for each entry and then add that to the quantity * price for the other entries. When I press my "total" button it's only doing the calculation for the first line.

Multiplying The String Representation Of REAL Numbers?
Jan 12, 2012<edit> Now showing the difference as a DECIMAL. Result looks like zero every time. </edit>Disclaimer: This code is provided "as-is" and should be treated as Freeware.( However any donations would be welcome as I have a "so-so" part-time job ).Please note all real numbers to be used should be in this format
"0.000000000000"Do not use numbers in string format in scientific notation like "1.2345E -06"I was feeling bored and decided to add to the code from JohnWein in this thread where I have used a routine that will multiply the contents of two long strings together.>>[url]I have now added a bit of code so you can multiply two really long numbers with or without a decimal point as a full-stop ( period or dot, call it what you like ).

VS 2008 Login With Textboxs?
Aug 3, 2010I am working on an internet cafe program for the desktops. This is how it works, the login files are stored on a ftp server in the form of txt files (E.G. USERNAMEpassword). The files are opened in the background of the program. Then once the login button is clicked, the two text boxes (passwords and username) will combine together and then in the background will look for the username and password as a single line of code.
login.txt:
johndoe12345678
jasmine373249273

open a txt file without the open file dialog and to save without the save file dialog.
P.S. I'm using a textbox.
