I need to save actual age (in whole years) for future use in the program. The problem is, 'Years' returns a big, fat 0 every time. Changing "Dim years As Integer" to Dim years As String" does exactly the same thing.
Code:
Dim myDate = New Date(Convert.ToInt32(Year.Value), Month.SelectedIndex + 1, Convert.ToInt32(Day.Value))

Create a project that determines the future value of an investment at a given interest rate for a given number of years. The formula for the calculation is Future value = Investment amount * (1 + Interest Rate)^ Years..Form- Use labeled text boxes for the amount of investment, the interest rate (as a decimal fraction), and the number of years the investment will be held. Display the future value in a text box formatted as currency. Include buttons for calculate, Clear, Print, and exit. Format all dollar amounts. Display a message to the user for nonnumeric or missing input data.Remember that the result of an exponentiation operation is a Double data type. Interest rate is annual.So far this is what I have and I am missing something(s) in the calculate process.[code]

Calculate the amount of money in the account at the end of 10 years.

You must a loop in this program. [code] I cannot figure out how to make the previous years balance become the next years and so forth.
View 6 RepliesI want to save an excel file with the following prefix: Order-Monday for Mondays, Order-Tuesday for Tuesdays etc and then this file will be overwritten the next week. For the following bit of vb

The program I am working on uses arrays and a text file. In one section of the program it's suppose to display the most active year for storms between the years 1990-2008. The year that has the most active storms is 2005, but I don't know how to write it in the code so that it displays. Attached is the text file.

View 6 RepliesI'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

View 5 RepliesI'm creating an application software. It has many features, which is in the base version of the software. And people could buy my software (which will be enough for most of them since it had all the common features needed) and use it. But some of them might need additional features to this version.So, I can add new features to the base version of my product and provide them a custom or extended version.
But my question is, how can I effectively manage these versions of the software while updating (or upgrading with new features which are common to all of them)

In the above example F1, F2, F3, F4 & F5 are the features available common for all editions of my software.Whereas, A1, A2, A3 & A4 are the additional features added based on customer's request.

View 3 RepliesI'm automating some outlook functionality in a .NET app. It works great. I am compiling it and using v 12.0.0.0 of the Outlook Interop assembly. My code should work on any version of Outlook so it seems silly to have to bind it to a specific version. Is it possible to use reflection to do this instead of compiling a reference? Are the interop assemblies on PC's by default that have Office installed anyway or do I need to include them with my application?

After right clicking on the form Context Menu give option to see 'View Code Window' which opens the the view code window and shows from the first line of code in the file, where actually it should show Event handlers related to the control on which Mouse was right clicked. right now we have to go through the line of codes to locate the event related to particular control.Also after double clicking on the control, VB inserts a default event handler to Code file which should happen only when there is no Event Handlers added for that control previously & if a previously added Event Handler present, double clicking controls should locate that procedure.[code]after dragging dataset table to the form vb assigns 'field name' concatinated with 'TextBox' to TextBox Control likewise 'field name' concatinated with 'ComboBox' for ComboBox Control where it is difficult to locate them in Controls Member list into code..Instead why don't you prefix them with 'txt' for TextBox, 'cbo' for ComboBox etc. It is then easy to find one in code. Or make the original Optional.
View 7 RepliesI have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.

I am at the stage of planning the application which will conect to a Ms SQl database, and process some data to Excel files.The problem is, that i would like to make a base pure application, without any functionality, and then add functionalities by adding some external files with code to program folder.I`not sure if what i just wrote is clear. To simplify:I would like to have an application which connects to a database, but let`s say when after 1 year, i will be in need of some more functionality, i woun`t have to change the code of whole application, but can just add a new file, and when I run the application there will be one more function to be chosen from the list.
