1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.
For example the function: Membership.FindUsersByName()
So that's how I want it:
If I re-size the form, the textbox inside should be re-sized to fit the form, NOT DOCK!

View 3 RepliesI'm redoing a program for my company and my boss wanted me to created the entire thing through functions...
For the task I wanted to know is it possible to have functions within functions?
Sort of like in C where we would have nested structures?
Its a FILE I/O, with robot commands, moves and verifications....
So I would find the line in an excel spreadsheet where it moves, the coordinate, put it into an array.
Take the actual results store them into a two dimensional array...etc, etc....
Another function would eventually compare the results with the moves, and within a tolerance.

View 4 RepliesI have made quite a good library for calculating Math problems like Quadratic Equations and many other. Now I met a friend, and hes programming a little in VB, and we were thinking if it is possible to import my functions from C++ to his code, so he can call them, when they are needed, so we can make a calculator? How can we do that?
Edit: My friend is using VB.net
Edit: My library is organized in free functions.
I am not sure if i am using these in the correct manner. Basically i have an app that downloads a file from an ftp server (i am kinda cheating cos i am using chilkat). Now if i put the code directly in the form i can get it to do a progressbar.value = ... in it['s own sub.What i decided to do was stick my ftp download parts into a dll i created. Created a function within the dll and i have a return on that which returns the message 'file downloaded' or 'no file to download'. But can i return a value to update the progress bar as it goes when the code is contained in a dll? Or am i totally missing the point and how to use dlls?
