I have a Visual Studio 2008-SQL Server 2005 app that will be throwing alot at it. It's my testbed learning app. I'm also a student of this craft(43 years young) like another poster posted on another thread. I come from a PICK/BASIC jBase background. Anyway as-is my app has a connection to the database that is opened on form load. I close the connection on form close. It's a one form app currently. Is this wrong? It seems that maybe I should not have a connection opened possibly all day. I'm looking into incorporating Datasets, dataAdapters into my next phase of evolution. I looked at the material and it's tough. For me anyway. But I will get into it. I will fetch the data into a dataset so that I can keep the connection open only for a little while. I was turned on to this "keep the connection just as long as you need it" idea from someth
View 3 RepliesI am in the situation on preventing connection leaks. and one of the possible solutions is to make sure that all opened connections are closed after transaction. That means closing the sqldatareader too.
I am confused on the part of closing the sqldatareader. if the method that will be read by sqldatareader encounters error, it is not successfully initialize. If this happens, i will encounter an error once i close the sqldatareader. does it mean the most proper way of closing sqldatareader is like this?

Is there a way to determine whether processes have been opened or closed during a given time frame? I'm working on code that will take an initial copy of your processes list, and then based on a timer, continue to take copies, which will compared to the initial processes list to determine which processes have been opened or closed until the timer ends. I'm capturing the processes list's in an Array list.
Dim processesList As String //Initial processes list
Dim processActivity As String //Opened or Closed processes
Dim processesAtStart As New ArrayList // Initial processes as ArrayList (To Compare)
Dim processesCheck As New ArrayList // Latest processes as ArrayList (To Compare)

I created another form that had a pic and two simple buttons, one button plays music the other will stop the music if played and take you back to the previous form. My problem lies in when the users uses the windows "x" button to flose the form, the music does not stop. I have searched and failed and light that could be shed would be awesome.Apparently I saved the wrong file and am not on my VB box so this code is incorrect. I basically added the music to the resources, dim'd it and activated it with a button. The other button not listed in this code was set to "portal.stop()" and "Me.Close()"
Public Class frmFail
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click

I'm working on a scoreboard, and I'm want to add a goal horn. The way it works is when a button is being held down, the horn wav file is going, and it stops when the button is released. I can make a good loop file, but what I'm having trouble with is getting a fade in and fade out effect to make it realistic. I don't want to use the master volume controlbecause there could be other sounds playing at the same time. How would I do this?

View 2 RepliesI'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?
View 2 RepliesI am using a Windows Dialog form in my VB 2008 project. I bring up the dialog form no problem with the following
Dim resultNewInc As DialogResult
resultNewInc = frmDialog.ShowDialog()
If resultNewInc = DialogResult.OK Then
...some code here ...
End If
And in the Dialog Form, the OK button has code
Me.DialogResult = System.Windows.Forms.DialogResult.OK
Me.Close()
But there is one problem. If I call up the dialog form again, the form controls have the text values that were typed in during the previous instantiation and a class which is part of the form was not disposed. So it looks like the form is being "hidden" and not closed. I tried to use the code form.dispose but it didn't work.
How do you check if all instances of forms (or simply all forms of an application) has already been closed?

View 1 RepliesSeveral years ago, I created a nifty data entry form that is called from a main menu. Due to recent user requirements, I had to create another form that is very similar to the data entry form. To prevent duplicate coding and testing, I created a class to inherit the existing data entry form. The issue is when I leave the class and return to a sub menu, the class is opening the main menu and the sub menu. How do I only return to the sub menu without the main menu appearing? Here is a snippet of my code. You'll have to scroll down to the very bottom to see the section that is causing issues. BTW, I coded the application in such a way that only one form should be open at a time.
frmMenu (main menu). This is nothing more than a bunch of buttons that allows the user to perform various functions.If user clicks button #1, open the data entry form:
Dim objFrm As New frmDataEntry
bolOkToCloseForm = True
Me.Close() '--- close the menu screen

I am currently working on a program that has several buttons in it lined up. Each button goes to different applications (.exe programs). The program I am making is suppose to be a fullscreen program and won't let you see any of Windows when it's running.
Therefore I want to make a "back" button that always stays on top of any application and when I push it it will take me back to my WindowsForm (startpage of the program).I am also wondering if you can make it so all .exe programs only can run ONCE. So if I press one of the buttons saying "open notepad" I want it to work so it can't open Notepad once again making it two notepads open. Just go back to the first Notepad opened.
We are creating a Chat Application for our chatnetwork, we originally made it in VB6 works like a beauty and converting to VB.NET At the moment, it joins the channel fine, nothing wrong with this displays everything it needs to however we are in the process of showing emoticons.While we were on XP in debug mode and release mode, the emoticons showed.Once we moved the compiled version over to Vista Home and Ulitmate the emoticons would not show, we have looked and looked all over google and have not come to a conclusion, today we even moved the whole Project folder over to Vista, ran it in debug mode, and the images still wouldn't show in the RTB.

What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?
