Multiple Times To Test It Out Sometimes Adding Code And/or Changing It?
Jun 6, 2012
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.

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 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.

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'm trying to develop an application which searches a sql server database. One particular search entered by the user actually sends seven queries to the database. I've designed it so each of the seven queries is conducted in a seperate backgroundworker, so that they run and return their hits concurrently. When the user enters a search term, a routine (runSearch) is called , which in turn causes each seperate backgroundworker to run.This work fine when the user enters a single search term.I'm now trying to allow the user to enter multiple search terms in a multiline textbox. I iterate through the lines in the textbox and call runsearch for each line. I assumed that the progam would wait for each call to runsearch to complete, before running the next.
I now find out this is not the case. When I call runSearch, the backgroundworkers are set in motion. The next line in the textbox then calls runSearch again, but the backgroundworkers from the previous calling of runSearch are still running. This throws up an error stating that the backgroundworker is still busy and cannot be called.I need a way to test that all of the backgroundworkers have completed before running runsearch again. If one or more of the backgroundworkers are still running

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

I have a report that displays some sales info. I have a query that takes the data from an SQL Server database and I store it in a dataset. Up to there everything is ok. The problem is that I need to print the same report using Crystal Reports for each row in my query. Is there any way this can be done? I call a form with a ReportViewer tool to display the reports, wich are basic .rdlc reports.

I know this sounds really bad but I can't seem to figure this out. I am creating a template to use in a form. I have a few buttons that when I click on them will auto type out text into a rich text box. I figured it out for just typing in the text into the richtextbox. richtextbox1.text = "my text goes here" But if I hit the button more than once it doesn't keep adding the text to the rich text box. How can you program a button to enter a text as many times as you click the button?

I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.
Heres code to reproduce it. Just a button on a form.
Dim intTotalTimesClicked As Integer = 0
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click

I want to update a database based on the form that is currently activated. I had originally decided to use the GotFocus event. However I now understand that will not work as the form has controls on it. So I then thought I wouls use the activated event. This works but seems to fire multiple times. I put in the following code:
Private Sub frmNewTicket_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
MsgBox("Form Activated")
End Sub
I select the form and make it activated and the message box appears about 15 times.Why does it do this? How should I handle this. I only want my code to execute once when the form is activated.NOTE: There are several forms that the users will be changing between, incuding forms from other applications.
