View 1 Replieshow to make a zodiac calculator, I know the basic codes that I need to insert, but I'm creating it in a windows application. The day and year are text boxes that the user can input that particular information, but the month is a drop-down box. My two questions are: Is it okay to delete the private sub of the day and year so I can combine them into one sub? And how do I get the months to show up individually in the code area? Or would I have to delete the drop-down box completely and make it like the day and year text boxes where the user can input the information themselves?

View 6 RepliesI am trying to make a simple resistance calculator for practice. I use text boxes to let the user input the current and voltage, and then a combo box for the units and then a list box to display the results. For some reason no matter which units I select it doesn't convert at all. For example 1/2 will always show up as 0.5 in the list box no matter which units are selected from the combo box. Here is my code.....I know that there is more cases but I only put one to see if it works before I write all of the cases.

I want to make a game statistics calculator. For this I choose to make a XML database with the base stats of the characters.
I've made a small XML file in the VS2010 project with 1 class stats and made a list to 10 levels (to lazy atm to write all 85).
the XML looks like this:
<BASIC_CHARACTER_STATS>
<Levels>
<level id="1">1</level>
[Code]....
On the Form1.vb I've to combo boxes, 1 to display class names and 1 for levels.
Also have some Labels to display i.e. the base_STR number. But after trying random stuff to get it linked and closed VB to restart again because it was messed up too much
I am working on a mortgage payment calculator that has three user input textboxes (amount, interest, term). The interest input is a MaskedTextBox masked to (00.0). The issue I have is that if the MaskedTextBox is has no user input when the calculate button is selected then I get the error "FormatException was not handled" "Input string was not in the correct format", I highlighted the section in the code below. I'm quite positive the error stems from the MasketTextBox mask of 00.0, the decimal I believe causes the issue when no other data is entered.

I made a Try-Catch statement so that if the user enters letters into the text boxes, they get an error message. However, if the user leaves one field blank, the error message still pops up. What's the code so that I can get Visual Basic to recognize that an empty field is the same as 0 so that that message doesn't pop up? [Code]. What do I need to add to it to get that Error Message to stop showing when the user doesn't enter a value into one of the text boxes?
