Call Module Functions Directly In .NET?

Apr 29, 2010

I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?

Call '.dispose' On Objects Inside Functions?

Jul 22, 2010

say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?

IDE :: Backgound Worker - How To Call Functions And Subroutines

Jun 10, 2009

Visual Studio 2008, Standard Edition VB.NET I have only limited experience using the background worker, and all that I've done with it thus far was fairly straightforward and worked fine.

I am now looking to run a process in a background worker which calls various functions and/or subroutines, but of course it generates an error indicating that it's on the main thread (or something like that - I don't recall exactly, but that was the crux of it).

Adding Call Functions For Defragment Hard Drive And Other .msc Tools For Windows?

Jun 2, 2011

My problem is that I am creating system tools for windows with a good gui and I don't know how to start with it. One of my difficulties is making code for calling any window tools for example, defragment.msc, backup, system restore, registry editor(I knew there's already a thread in here but it is closed).In short, I will create a "Utility tools ALL IN ONE" for my project somewhat like a registry cleaner or advance system optimizer and the likes.

Excel Maths Functions And Calls To All DLL Functions Documentation?

Jan 29, 2007

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.

Differences Between VB Functions And Convert.To* Functions?

Feb 19, 2009

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?

Create Functions In Functions

Jul 1, 2011

I'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.

Using Functions And Dll's

Jul 27, 2010

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?
