How can I change the IF statement to accept the ascii code of decimal points? Then... how can I make sure the user doesn't enter 354.5.3535.5.0 as a number? Is there some sort of built in library in VB that has a pattern matching for US currency or do I have to write it myself?
I have a series of text boxes with numbers. They are an array called txtBF(0 to 16). I am trying to take the value that is to be displayed in the text box and make it have only one decimal place. I have tried using this code below but I keep getting an error message Run Time Error 13: Type Mismatch.
txtBF(11).text = Round(txtBF(11).text, 1)
and I have also tried this
txtBF(11).text = Math.Round(txtBF(11).text, 1)
How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

View 7 RepliesI have an id called "AM01". I separated them by truncating the numbers out and increase it by 1 each time I want to add a new record. Therefore before I add the record, I would have to combine them back. I managed to truncate them and combine them back. However, the results turn out to be "AM2" instead of "AM02". So, is there a way where I could make the numbers as "02" instead of just "2"?

View 2 RepliesI am trying to move some data from an Excell sheet to an AS/400 file.
I have my app working, in that, the data is getting to the correct table, but the problem I'm having is that one of the columns in the spreadsheet contains numbers ie; 1234.55
I need to get that to the AS/400 as 123455 in a text field.
Currently I am moving the data from one dataset to another as follows.
Dest_DS.Tables(0).Rows(i).Item(0) = Data_DS.Tables(0).Rows(i).Item(0)
I think what I need to do is seperate the whole number from the decimal and then concatenate the values. ?Not sure how to.
Also, some of the values in the spreadsheet may end in a zero such as 1234.50 but only show the 1234.5 so even fnding the decimal and then taking the next two characters won't always be correct.
I was wondering how i can get as far as the second point in a Double.

View 2 RepliesI have read about Round() and MidpointRounding.ToEven but I still could not figure how to use it to achieve what I want. I have numbers (usually from 5 digit decimal) such 125.36 , 125.10, 125.99. I want to make the 2 decimal point rounded to the nearest 20. Means, the 2 decimal point should be either .00 or .20 or 0.40 or .60 or 0.80 only.
125.36 should be 125.40 : 125.10 should be 125.00, 125.99 should be 126.00
125.54 should be 125.60 and so on

I'm drawing polygons,lines,etc. and I have to have the points of each precise - up to 12 decimals. Since a Point only takes integer values, I'm not sure how to handle scaling.
