Separate The Two Procedures And The Events?
May 10, 2009
I just happened to be reading through a post and stumbled upon this and was curious. As I was remiss to go off topic in someone else's post, I've dragged it out here.What we are doing here is logically incorrect. We loop thru all the records and set the sheet locked state and button image. But since the button is just one element, so effectively the image set would be that of the last record.We need to separate the two procedures and the events they take effect too.Ideally we should set the sheet locked state while loading it. (maybe the form_load event etc.). And we should set the button image when we switch the sheets (e.g. sheet change/activate events). The selection of events however depends on your requirements and wisdom.
[code]...
I noticed how the image was accessed above. My question is this, what is the differences between the above method and Image = Image.FromFile(Path) and if any, what are the advantages/disadvantages of each? This is just for knowledge purpose and is not pertaining to any particular problem.

I am playing around with VB 2010, and I want to create a separate file with different procedures etc so that I can call a proceedure etc from this file I have a simple form with a single label on it, and a seperate file called filelib.vb.In the filelib.vb is a proceedure called LogicalDriveTypes
Public Function QueryLogicalDriversNames() As String()
Try
Dim Totalstring As String
Dim ds As Int32
[code]....
In my form1_load I have Label1.Text = filelib.LogicalDriveTypes and I get "reference to a non-shared memner requires object reference. How where / what do I do to access the proceedures / functions in this other file any time I need to from this form ?

I'm trying to automate a product that provides no such automation capability.I've take a cursory look at loading the app in a separate AppDomain, and also, through reflection, executing the Program.Main() to get the app running. I also tried getting the windowhandle from a separately created Process object (which I've learned will not work).If I have a reference to their assembly added to my project so I can reference an instance of "TheirProduct.FormMain", what, if it's possible, is the best way to go about capturing events from that form? What I need to do is to be able to capture a couple events, and perform a few Button.PerformClick() against the form.

I've been searching for the answer for a while but can't find it yet. Basically so far I have a simple VB.Net form with one button.I would like to make a class or module that can handle events from the main form. This is my code so far but it doesn't seem to work.

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?

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. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

I have a function in my program that adjust sales for multiple days. Sometimes it needs to adjust up to 3 months and the tasks takes a while so I decided to split up the work between multiple threads. The way I have it working is say I need to adjust 3 months. I have the first thread adjust sales for the 1st month, the second thread adjust sales for the 2nd month and finally a third thread that will adjust sales for the 3rd month. Since all three threads are performing the same tasks except for different date range they use the same procedures. Within those procedures I make a call to the database to extract the sales for the given month. At some point it seems like the threads start to use the same SQL Data Objects because I am receiving the below error."There is already an open DataReader associated with this Command which must be closed first."Below is the first procedure that is ran by each thread up to the line where it errors out.
Private Sub Process_Adjustments(ByRef objAdjustBillCodeThreadParameters As clsAdjustBillCodeThreadParameters)
Dim cmd As SqlClient.SqlCommand
[code]....
So all three threads call this subroutine and the first thread does the data fill with no issues and then sometimes even the second thread does the data fill with no issue but then the third thread crashes and produces the above error. It seems as though the threads are sharing the same SQL Objects when all objects are local to the sub and I always thought each thread had it's own memory to work with. So I thought each thread would call the sub create it's own objects in memory, but that does not seem like what it's doing. I have other multithreading processes in my application that work perfectly fine, this is the first time I am attempting to multithread in this manner where I am using the same procedure within multiple threads.
Just thought of something that I might be doing wrong. The subroutine in question is in the same class where the threads are created. Should the subroutine be in it's own class, and therefore each instantiation of that class?

I've lived in the VB6 world for the last 15 years and am only now starting to learn .NET. I've got a long way to go, but I am hung up on a fundamental issue about collections.I live and die by collections in VB6; I use them for just about everything I do.So I am very used to having the abilities that the intrinsic VB6 Collection has.Things like adding items with keys, referencing items by key or index, having the "Add" method return an instance of the object, being able to add custom procedures to the collection, having it strongly typed, etc.But all of the collection information I have read about in .NET doesn't really do all of this.(I am starting out in VB.NET, with the possibility of moving to C# at a later time, so i am trying to stay away from the Microsoft.VisualBasic namespace.)

I have a Custom.ascx file that is used on a number of pages. Custom.ascx contains a couple of controls and a button called cmdCustomPageButton. When the user click on cmdCustomPageButton, cmdCustomPageButton executes a Protected Sub that gets some data from a database.
Page1.aspx that is using Custom.ascx has its own set of controls and procedures that it executes. It contains a button called cmdPage1Button and a procedure called RetriveData that is being called by other procedures as well within Page1.aspx. When cmdPage1Button is clicked it calls RetriveData. RetriveData is only applicable to Page1.aspx. Page2.aspx and Page3.aspx both has a procedure similar to RetriveData but is only relevant to its own page.
Try to explain using code:
Custom.ascx
Public Class Custom
Protected Sub cmdCustomPageButton_Click(Byval sender as Object, ByVal e as EventArgs) Handels
[CODE]..............
The question. How do I call the different RetriveData procedure form the relevant pages being it Page1, Page2 or Page3 when cmdCustomPageButton is clicked ?

calling stored procedures using ADO.NET. We have an application developed, which uses SQL Sever as backend and Visual foxpro as front end. In this application every thing is done by database only. That is all insert, update, delete operations are done by SQL Server only. So we have to provide some input and output paramaters to stored procedures. Some time these procedure carry out insert, update, delete operations as well as return some data in the form of tables.

I have a block of related sub routines I would like to "group" together within class to make navigating a littel easier. When I say group, I mean achieve the same functionality of being able collapse and expand a block of code as would with single procedure or class. Two alternative ways I can think to accomplish this is either use a partial class for those procedures or use namespace. I just wanted to see if VS for VB.Net had another way to be able group and collapse blocks of procedures.

Am looking for a Currency Text Box control that will accept numeric key input and display entry as Currency according to Users Regional Settings.
Additionally, when an assignment is made such as Currencycontrol.text= 123.45 + 500 , user will see value displayed as $623.45 or formatted to regional specifications.
I do need a control rather than formatting procedures since my form could have 24 or more currency fields.

I initially posted this in the wrong forum. I need help getting this to run properly. I'm trying to construct a fractions calculator. In order to complete it, I need to do it like this:Using Select Case statements, four Function procedures should be called based on the operation selected. Each Function procedure will calculate the correct operation and return the Decimal value to the calling procedure. The original procedure will print the result.
Now, the result should be calculated to the hundreths place and the input values should be validated by a Try-Catch Block.And of course, I've been having trouble with how to do this. I've attempted many times and this is what I have so far:
