The functions still work correctly (as far as i can tell) what would i need to do to the above function to remedy that warning?
How can I handle the above warning? Should I just return nothing when an error occurs?

I have a function to recursively search through windows (and their child windows) to find specific ones, it works exactly as expected, however it causes "function doesn't return a value on all paths" warning. This is the only warning in my entire program, and although it might be silly, I'm interested in knowing if there is a way to stop this error from occurring, but still allowing the function to work properly.[code]

I have a function that returns a double. If in the function I decide the value is invalid, is there any way to return "error" instead of a double? Of course I could pass a boolean by reference and set it false and then check for that back in the calling function, but that seems awkward.

I'm using VB6 and trying to get an instance of a Type Library object.After i retrieved the object and i'm trying to invoke a method. I'm getting this exception. However, i've checked with the parameters and its type. it is correct.I found something fishy, that method doesnt have return value. But it is throwing a compiler error whenever i'm trying to call the function and the compiler error went off when i get a return value from that method.I don't know,
View 1 RepliesLets say I click a button on a form that calls a function in a data access class. This function inserts a record into a table in a database. The function returns an integer value for the record id of the newly inserted record. Now lets say the insert failed (syntax error, timeout, whatever). I can return a zero to the calling routine to indicate the failure, but not the error message. So in general, what's the most appropriate way to handle getting information back to a calling routine when the return parameter data type doesn't allow it?

I am writing a program with multiple forms (for inputing loan/financial information - so they are set up exactly the same albeit a form number (ie: 1-6)) that feed into a summary page form to display each individuals form's information. When the user closed a financial form, it then feeds the information to a summary page using the code I have below: [Code]. I am new to working with functions, and have not been able to find anything that can show me how to fill multiple textboxes with them (I only know how to return a variable using the function to work a calculation). Any way that I can write a function (or any other call) for this would save me a tremendous amount of coding, and make debugging worlds easier.

The functions are called the same way, so what is the difference?2. Why in the second code, the variable FutureValue is allowed to have the same name as the function?
