Validate Textbox 2 Decimal Places?

Mar 30, 2010

I currently have a calculation that gets performed based on the type of operation a user chooses on my form (+, -, *, or /). I have it check their answer against the correct answer and tell them if they get the answer right or wrong. I need to know how I can check the answer when they choose a division sign that checks only the first two digits of the lbltxtAnswer label. I also currently have a validation that checks for numbers only, so if the user types in a decimal, the error message displays, which I don't want it to do. Here is my calculation and validation [code]...

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

Truncating Numbers To Remain It Two Numbers (Not Decimal)?

Mar 19, 2009

I 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"?

Disregard A Decimal Point?

Sep 24, 2009

I 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.

How To Get Comma Instead Of Decimal Point In Label

For some time I try to get the comma instead of the decimal point, but the labels I use won't display a comma. For some reason I don't understand, the msgbox() does the trick, but is useless in my application. This is my last desperate piece of code I tried but it also failed.

Expresserprijs = EuropluscolNL(ArrayCol, 2) - EuropluscolNL(ArrayCol, 1)
' All above are "Doubles" and are fed with data like 21,45 (with comma's that is)
Decimaalteken = Expresserprijs

Inserting A Decimal Point To A Number?

I am trying to think of a possible way to insert a colon and decimal point to a part of a number. I am making a Rubik's Cube timer, and I converted the times to milliseconds so I can calculate the average of 5 with that. I averaged the milliseconds, but now I need to convert that into minutes, seconds, and milliseconds. Does anyone have any idea on how I would go about this?
