Having A Selection Of Code Once To Use Multiple Times In Differnet Places
Jun 8, 2011
I know that title is kinda miss leading, but i couldnt figure out another way to explain it. I know theres a way, but I dont know how to do it.Ive got a Save code that I have about 5 differnet times in my application. How do I make it so that I can just type in something like Do Save, and it locates the save code and follows it through, then returns to where it was.

How can I tell something to use a code without completely adding it in that sub again? I have some code that will be used alot within my program. I could write a DLL, but I don't know how to use those!
Here is my code:
Dim str1 As String = System.IO.File.ReadAllText(Me.OpenFileDialog1.FileName)
Dim s2 As String = str1.Replace(".[1gs5]", "a")
s2 = s2.Replace(".[u775]", "b")
s2 = s2.Replace(".[fsef]", "c")

I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something

I have written a program and have used it (in debug mode) multiple times to test it out sometimes adding code and/or changing it. After a while any code I wrote or new buttons or features I added to the form would not appear while debugging. I don't know what circumstances led to this.
The only solution I found was to rewrite my code from scratch, however, the problem came back after a while. I don't know what is going on and I can't move on without starting all over again.

I am currently making a little program for a school carnival.It contains a timer linked up with a USB controller with eight buttons (physical) attached to it. I now want to be able to take the times it produces, sort them and add the place of that runner.

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..

I have written a program for cleaning my pc. I want to be able to start the Form1 (which opens the entire program) from the start menu. And I would like to run Form2 (which runs just the scan) from the context menu of the recycle bin. How can I open Form1 from one shortcut and Form2 from another?

In a program that I'm responsible for, we want to start keeping track of milestones. These milestones are quite simple and consist of a unique identifier, the project they're assigned to, a description, and a date that they should be accomplished by (or not, if there's no concrete due date).We use a slightly modified Model-View-Presenter architecture, and currently I'm passing this list around through the presenters, but it seems fairly clunky, so I was wondering:What's the best way to make this list available to all the presenters/views that need it?We're using VB.NET 3.5, and I was toying with the idea of making this a shared property of the main presenter, but it does seem like that adds some unnecessary coupling.

I have created two structures, one named "Product" and the other named "Item". These structures are quite similar but are at the same time quite different from each other. The structure definitions are as follows. Ultimately, I declare arrays in my containing class which access these structures as a type. Their declaration: "Products() as Product" and "Items() as Item". All has been fine and dandy until one day, I go to change the items Enabled() values, and something happens. Not only does it change the Items(index).Enabled(index) value, it does it on the corresponding Products(index).Enabled(index) value, even though it was never specified to do so. Also, nowhere in my coding have i defined this sort of thing to occur. It is rediculous, because I watch it happen. I turn on the watch window, and debug one step at a time, and every time, I watch the Item line step, I look down at the arrays of products and items, and both values have changed. How do I get this to stop, and only change the Item.Enable value??

How to work a sub procedure. I'm trying to follow my instructors example, but I get a red box around my code in two places, with large red bullets on the left side of each. The program I'm trying to follow is underneath solid line.
First code that is flagged:
Private Sub DisplayResults(ByVal Name As String, _
ByVal Hours As Decimal, _
ByVal Rate As Decimal, _
ByVal GrossPay As Decimal)
And this
OutPutString = Name & " Pay" & Environment.NewLine & _
"Hours: " & Hours.ToString & Environment.NewLine & _
"Rate: " & Rate.ToString("C") & Environment.NewLine & _
"Gross Pay: " & GrossPay.ToString("C")
The flagged code says, "At form1.vb,line 23 character 5('DisplayResults')
2nd Grouping of code that is flagged says, "At form1.vb,line29, character 9('Display Results', line 7")

So I took this from an example. GetInstance() is called from hundred different places in my program, and when I debug, the line "Prog = New Program" keeps getting hit for each of those calls. Which I thought was exactly what should NOT happen.. Or do I have some fundamental misunderstanding?
[Code]....
It seems the "New" sub triggers a number of calls to Program.GetInstance, before the first one completes. This is due to me earlier having lots of shared public objects in this class, which are no longer shared since the class was made singleton. And these objects, when initialized, calls the Program class for reference to other of it's objects.

I have one Private sub that runs in a loop. I want the sub to run multiple times at once. For example the program runs, you press start; you run the program again and press start, again and again... the same program doing the job at once. now i just want one program do to it alone. But i would like it to be user defined. exp. run program. type in a text box 10. press start. and it works as if 10 of them work open working on the same thing.

I have a button where I get data from a database that matches a search string I enter. Everything works fine the first time the button is clicked. However, if I click it again with a different search string, I get the same results as the original search string. I've tried to dispose, clear, and reset my dataset before I load the data each time, but it still finds the original query. This is the code I use to get and request the data:
Private Sub btnCfind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCfind.Click
mdbFile = "TCICUST.DBF"
mdbCond = " WHERE COMPANY LIKE '" & cbCust.Text & "%' ORDER BY COMPANY "
GetDB()

I have a DGV in VB.Net 2008 connected to an Access DB table. The DGV is not Read Only, but is full of read-only columns except for one, which contains a combo box. The combo box allows the user to select an outcome for that particular row, and then the program copies in a pre calculated value into the "Profit" column depending upon the item selected in the combobox. Then the user hits the Save button and the DB updates (currently via SQL methods in the XSD).
Easy enough so far.
Here is the code.
Private Sub DGUserBets_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGUserBets.EditingControlShowing
[Code]....
The problem I have is that it would seem that if a user selects the desired outcome from the combobox but does NOT hit Enter, and simply mouses on to a different combobox to again select the outcome for a different row, the first eventhandler is not disconnected and thus the events fire multiple times. This then causes various default MsgBox errors and brings up problems when the user tries to commit all changes to the DB/exit program etc etc.
What do I need to do? Do I need to .EndEdit somewhere appropriate to force the row to save the changes? And where should I call this?

I am trying to programmatically add an unspecified amount of new UserControls to a form. One will be added every time an entry is selected in a ComboBox contained within the UserControl. Problem is, the SelectedIndexChanged event fires completely erratically. Sometimes twice, sometimes 3 times, etc., but never just once. No matter how many times I set the combobox's SelectedIndex to -1, it fires at least once with a SelectedIndex of 0. Sometimes the Itemselected event fires multiple times inbetween SelectedIndexChanged events.
InvoiceEntry.vb snippet:
Public Event ItemSelected As EventHandler
Private Sub cboItem_SelectedIndexChanged(sender As System.Object, _
e As System.EventArgs) Handles cboItem.SelectedIndexChanged
RaiseEvent ItemSelected(Me, EventArgs.Empty)
End Sub
