I was curious if anyone has heard of writing a program with functions only. It is part of my current assignment but all the examples I have seen all over have at least subs for the click events. SO I am a little confused to say the least.

What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).

I am making a program to deal with sine/cosine functions
If rdbsideA.Checked = True Then
Do While AngleB > 0
SideA = (SideB * Math.Sin(txtAngleA.Text)) / Math.Sin(AngleB)
Loop
MsgBox("The Length of Side A is ", SideA)

That is if the user seleects to find side a. When the messagebox pops up, it doesnt state the previous calculation, why is that?
I have a program and the program works fine. The only thing is that I want to shorten it up and stop using the same code over and over. I use the same redudant code through out the code. I want to write some functions in order to stop from having to use the same code over and over in my program. I wanted to know if someone could help me with functions: Here is part of my code below.

I am new to using VB2010 (and coding in general). Also brand new to these forums . Okay so I am making a program that: allows the user enter the number of customers served for each of 12 months into an array. The application should calculate and display the following statistics: total number of customers for the year, the average monthly number of customers, and the months with the highest and lowest numbers of customers. Use inputBox to get user input. Do not accept non-numeric or negative numbers.
The problem that I am having is that I do not know how to display which was the best and worst month. I imagine I need something that targets the highest/lowest number and finds the text in the corresponding index but I'm not sure how to do this.
I've been fighting for weeks now to make a simple music playback program. It would function much like Windows Media Player without the visualisations and playlists. I'm writing this on a Win7 box, but it needs to work on XP and newer.
I say fighting because I'm severely annoyed at how MS has worked some items and it's taken many days to go through everything only to find that it doesn't work.
I started by using WMP in VB Express 2010 and having it play my music. Simple, but not portable. I copied my .exe to a WinXP machine and it blew up. I copied it to a different Win7 machine and it doesn't run (I can double-slick all day, nothing happens,
no log entries, nothing....)
Then I find that there is an issue with the GUID of media player on different computers, and it'll most likely fail to run when you try to use it on other machines than the one the program was built on.
So I gave up on that.
I then figured I'd use DirectX. It's on XP and newer already, and is supposed to be backwards compatibile so if I build my app on Win7 it should still run on XP and such. I did that, and it works fine on the machine I built it with (again). My shuffle works,loop/repeat works, got my own version of a playlist and it all works. I copy that to another Win7 box and it doesn't run at all. It's setup as .NET 3 so I can be sure of compatibilty with WinXP.
For grins, I gutted all the code in my VB app involving calls to Directx and built that. It runs fine on other computers, including my XP test box. So I know the problem revolves around DirectX somehow.[code]...

I have a program that I need to operate functions based off of hotkeys.One of the most important things I need to be able to do, is hit Escape at any time and end the program.Remember, the program form will not be up, it will be a number of any other applications, I need like a global hotkey or something.
View 3 RepliesAs I develop code, I often want to unit test some of the building blocks of a class even if they are normally private. If my unit tests are inside the project, I can use "Friend" to accomplish this and still keep the functions private for normal use. But I would rather move my NUnit tests into their own separate project(s).
View 3 RepliesI'm working on a CNC control program, based on a DLL that someone else wrote. No problems with that sofar, as i get good support from the writer.
The problem i do have to tackle is the following: I want to acces all the functions by means of softkeys ( the F-Keys at the top of our keyboards ) when the program starts it shows the Main menu softkeys ( F1-F12), and each F-key has a function assigned to it, some will make the machine move, others will show another menu, or a fileopen/save dialog, depending on the chosen keys.
All works fine and handy-dandy, except for the F10 key, it seems to be "Sticky", when i press it, the program will not react to any other key, only the F10 key can get it back in "normal state" accepting every key with a function assigned..
How to "unstick" the F10 after pressing it?.. because pressing F10 now, means no other key will do anything, and that may become dangerous, when the machine is moving and it must be stopped..
Okay, so I'm doing a card game and I'm trying to set that when picturebox (PictureBox1) is clicked, a random card from 13 cards will come visible. Problem is, that when i start the program and click the picturebox, the same card will always come visible. As you can see i've put a button (Button1) which will hide every card. If I press Button2, then Button1 and then the PictureBox1 it will show differend card, but the cards which come visible are always the same.
e.g i press PictureBox1 (which will make card visible), then Button1 (which will make PictureBox1 non-enabled) and then Button2 (which will hide every card and make PictureBox1 pressable). Lets say i pressed the PictureBox1 four times and i got cards: 9, 6, 7, 3, then I close the program, start it again and press PictureBox1 again 4 times and it will show the same cards (9, 6, 7, 3). How can this be done that it will not show the same cards always?
Here's my code...

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.
I used to develop applications in VBA, but now I'm using SQL Server 2008 Integration Services for a lot of the functionality, and using VB.NET as the scripting language where needed - all of which are new to me. I need to do the same string manipulation in several different SSIS tasks. With VBA, I'd simply write a function and declare it Public, and I could use it from any module. E.g.
Public Function MakeId(ByVal Country As String, ByVal Postcode As String) As String
....
End Function
' later...
Dim MyId as String
MyId = MakeId(County, Postcode)
But when I do that in a Script Task or Script Component, I find I can't call the function from VB in any other Script Task or Component; it says MakeId is undeclared. It works within its own 'box', but not from anywhere else.

I'm taking a class in VB, so I have numerous projects. I have a lot of useful functions and code, and I'd like for them to all be included in on piece of code that all my projects can use. The problem with DLLs is that when I build, the EXE needs the DLL to be in the same folder. I want a standalone EXE file. Is there any way I can have a DLL in a different folder than the EXE and still use it? Or is there some better solution to having useful code somewhere so when I update that code, it will affect all of my projects?

i have an application that's in development, but some modules of the application are already built, so the application it's installed in several computers. In my code, i call an external class that i built with several functions that i use in multiple applications, in this class i have a small piece of code that checks in the network (internal), if a new version of the application (Msi File), of the current application it's available, and if it's available, it runs the Msi file.
msiexec /package MSIPackage.msi That worked fine in windows XP, but now some machines have been upgraded to windows 7, and the user need other credentials to run the package. (Elevate Privileges). Other problem it's that in my application i create several folders in the installation and the user doesn't get any permissions to write in the folders.For example i have one Log folder, and i can't write any logs to it.
This was sort of discussed in another topic i made, but it went a little off topic, so i'm making a new thread. Anyways
