When I code in PHP I usually keep my functions in a separate file functions.php, I am going to write a small function in VB, is it ok to keep all my functions and subs in the 1 file linke in PHP? will they be available in all my form code?
View 3 RepliesWhen you refrence a Function like this one:[code]You may want to be able to get more out of that, like this.[code]So how would I be able to add subs or functions onto a sub or function like that?

I don't mean to sound unintelligent, but is there a way to insert your functions and subs into visual basic and call them from and program made in visual basic? I don't want to have to put the code in over and over again.
View 8 RepliesI was wondering how to implement a vb script file with functions and subs that can be used in all code pages of a project. Similar to the old VB 6 bas files.

I'm not receiving any errors or any thing I just need figuring out the logic in this program. The Program Needs to Accept Input in One text box and adds n numbers together and displays the sum using only subroutines and Functions.

I want to create SETUP for vb.net window application. My application uses multiple dll.so I want to keep dll in separate folder and exe in separate folder. When I create setup, dll and exe are in same (Application Folder of setup), then it works, but when I create 2 different folder in Application Folder of setup, one for dll and one for exe, then it desn't work. Please suggest how can I ?when I create set up then all goes to applciaton folder. when i installed then all are installed in same folder.but I need all dll goes to sperate and exe goes to sperate folder.
View 1 RepliesEarlier I was working on a project, and I added a StatusToolStrip and the the ToolStrip I added a label and a progress bar. The label will say the current sub or function that is in progress and the progress bar will show how far along it is through the sub or function. I have tried this myself but I cannot figure it out as I rarely use progress bars.
An example of a code that I would like the progress bar to show would be like this:
Private Sub StopServer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StopServer.Click
'Checks to give server notice
If My.Settings.warningmessages = True Then
Dim cmd As String = My.Settings.warningmessagetext(2)
[Code] .....
So while the sub is running the label would say "Stopping Server" and the progress bar would show how far along the sub is.
This is very basic about the layout of classes, subs etc. 1. Should all my subs & functions always be inside a class? I haven't used classes too much before, mostly just a bunch of subs in a form file. Now I downloaded a sample program which I want to develop. This has all the code of the form inside "Public Class Form1": [Code] The code is an example of use of the ZedGraph library. It produce a simple window with one graph/chart. Now I want to develop this code with several tabs, a dusin different charts, file I/O and so on. I'm ok with most of the specific coding, but my question is on the general coding;
2. Should I continue my subs&functions inside this form? inside this class? inside a new class? Earlier when I've NOT been using class, I can make global variables by placing the "Dim" outside the subs. This does not seem to work within a class. 3. Should I avoid global variables all together, or how is this done without always passing arguments?
Also I will make more forms, for program options etc. 4. Should these forms be coded as classes? or just subs&functions in a form? Obviously I'm not well trained on the proper use of classes and have trouble to find this easily explained.
I'm trying to create a .dll in VB Express with multiple functions and subs.
For the .dll program, I create a class module with:
Public Class Class1
Public Function ReturnOne(ByRef MyVar As Integer) As Integer
[Code]....
Upon execution, it tells me that it cannot find the entry point in the .dll.
At the head of a module, I wish to declare some global variables for use in various subs/functions.
What is the difference between.Dim x as string and Private x as string / Public x as string, and when would I use one over the other?
I am porting an app from VB6 and I run into problems with references to functions and subs. Basically, let's say I have 2 classes added to the project, like this.
Public Class OOOOO
Public Shared Sub BBBBBBB(ByVal FileName As String)
...
Call CCCCCC()
Call DDDDDD()
etc.
...
End Sub
[Code] .....
I had to make the BBBB() shared to be able to call it from another function AAAAAA() from another class PPPPP. However, I get error on the references in the BBBBB(), that CCCC() and DDDD() have to be made also shared (so instead of 1 error I got number of errors).
When I tried to make them shared as well, I got tens and tens of errors due to other references of both variables and functions.
I'm trying TCP communication using VB.NET and using the TcpClient method.All is working fine but I'm having trouble keeping my message seperate from each other.For example, my message have an header and footer and can range in size from very small (32 bytes) to quite large (64k). The problem I have is that when messages are being sent quickly they will arrive together. For example, if two 32 byte messages are sent they will arrive as 64 bytes. This is no good as I need to process them seperately.
So my question is:- Is there a way to easily separate my messages using a built in feature of the TcpClient so that the "reading" will give me the correct amount of bytes each time corresponding to the amount of bytes I have sent per message?
When I create more than one instance of the same form and I call a method on any of these instances, the code only fires on the most recently created instance. Even when I click a button on that form, it executes on the other form. How can I call these and keep them as distinct objects?
For example: if I build Form1 with a public method called ChangeMyColor and a button to call that method. Then in the main app I set MyForm1 = New Form1
and MyForm2 = New Form1, then call MyForm1.ChangeMyColor, the color changes on the second instance. Even if I click that button on the first instance, the color still changes on the second.
How do I pass parameters of LINQ DataTables through Functions and Subs
View 1 RepliesI have a number of unrelated subs and functions that do various things on my server (e.g. Lighting control, data caching, server maintenance, etc). They are all in various classes which I have coalesced into a single solution.My goal is to create a single, simple interface which each of these disparate classes can be integrated and called from a command line interface. Instead of hard-coding a longish case statement which parses arguments and passes them to the various subs, I wanted to make a generic class which can be instantiated with a minimum of information and put into a data structure. Ideally, adding a new function would involve:
1.) Providing the function pointer (Delegate). The delegates will have various signatures. This is the crux of the question.
2.) Providing ancillary info such as the command-line callable name, number of arguments, argument types, etc.
I have a 100% working class called "node" which is basically a hierarchical tree of node instances. I can use this to simply organize function calls in related branches. All is working quite well.NodeFunctionDelegate(ByVal args As String) As String.The node takes the arguments passed to it by the command line and sends it as the "args" string as comma-separated. The delegate function then needs to know how to split up these comma-separated values, type them, tryparse them and etc. It then must return some string.It works, but it involves writing a middle-man function stub which can receive the argument string from the node class, do the parsing and type checking, and then call the destination function.My goal is to eliminate this trivial middle-man function. The problem is, I can't figure out how to create a variable-signature delegate for the node class.
I have an application that queries DHCP and pulls scope/subnet information. There are roughly 8k scopes on our network to query so reporting this data takes a little bit of time. I currently have this running on it's own thread and reporting to a progress bar so the applications doesn't seem inactive.
The DHCP api functions can report a total, a max read and a resume argument. This means that I can, in theory start 4 threads and have each thread read through 2k subnets, so it will only take 1/4 of the time to read all this data. Would I need to create four separate background worker handlers, do_works, runworkcomplete, report progress etc.?
I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
i have have a few questions about the syntax of the lan.:
1) What is the 'Get' statement and when do you use it?
2) Whats the difference between public, private, protected etc... when declaring functions and subs.
3) When would you use the overrides property?
Namespace MyClassLib
Public Class MainClass
Public Sub New()
[CODE]...
Is it possible to make it so that the user using the Class Library has to declare a new Instance of MainClass() before using Subs/Functions in Class2 or Class3?
I have an application that I am reworking. It has many reports and a pain to compile and roll out.I'd like to make a root user interface that "calls" the functions and subs remotely.I was concidering pulling them and making formless exe's of them, passing the needed criteria via command line. Yet still be able to update and control them.
View 4 RepliesI did a super simple calculator with ASP.net with five buttons: add, subtract, multiply, divide, clear. There are five separate functions for each button's click event. For example: Sub addfunction(ByVal s As Object, ByVal e As EventArgs)If Not IsNumeric(input1.Text) Or Not IsNumeric(input2.Text) Then resultLabel.Text = "You entered an invalid or missing number"
[Code]...
How might I be able to combine all 5 of these functions into one? So for example, all the onclicks will refer to the same function, but will somehow be able to determine which button was clicked? I forget a lot of VB.net from a year.
Here is some example code of what I mean:

Public Class Form1
Private Sub Button1_Click(ByVal sender as Object, e as systemEventArgs) Handles Button1.Click

As 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). How do I achieve the effe vb.net 2005?

...VB express... I recently got a new computer, and then realized that a text file that I opened and read from in one of my apps was not there anymore.I copied the project from my old computer but forgot about the text file. the project's file pointed to it's folder, and the text file's path was somewhere else Is there a way I can keep a file with a project when it's compiled, and then how do I set the path in the app so that the file is found when I want to read it?
View 12 Replies1) Transcription company uploads .txt files containing transcription onto one of our servers for importing into SQL Server. These files have some minor formatting, usually just grouping of text with linebreaks and would look something like this:
</br>CHIEF COMPLAINT </br>"I was a little hungry."</br></br>HISTORY OF PRESENT ILLNESS</br>

When the content of the imported text is viewed in the web application forformatting (</br>) is presented correctly3) Due to a server upgrade (upgraded from SQL Server 2005 to SQL Server 2008 R2) and source code corruption this application had to be recreated using vs.net 2010. After I recreated this application I am finding that the text is no longer keeping the formatfrom the original file so that all the text is clumped together. I have attempted to use the replace function of the string to replace </br> with vbcrlf but this is still not working.
I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number.
