Getting Progress Bar To Follow Subs And Functions?
Jun 2, 2011
Earlier 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.

When 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 have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

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.

I 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.

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.

How do I pass parameters of LINQ DataTables through Functions and Subs

I 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.

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?

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 have:

I have two forms, when the user selects a button, the second form opens and an external executable begins an automated process. The point of the second form, is to only show the current progress of the automated tasks and closes when those tasks are completed.How would I use a progress bar to show the current progress of an action on a different form without knowing how long it will take?
