i am doing a project which will display real time ecg on vb application.
i just wanted to know that.. is there any way that we can display ecg in vb6? How?

VB6 is deprecated, meaning that it's no longer actively supported. If you're going to write new software, use VB.NET.
Can you give me a good reason why this "needs" to be in VB6?

Hello all,
I want to try and do something that I think should be fairly easy, but I could be wrong. I want to have an icon in the system tray and it would change colors and blink depending on the system status.
Green - All systems are up and running
Red - There is a system down.
Yellow - Scheduled outage for today.
Orange - You are not connected to the network.
Ia m not sure how to even get started. I have written code, but not a lot of VB more VBA, ASP, Javascript. Would I create a service for this. I was thinking about having the icon check for a file.
So if the file is called Green.txt The icon would be green and if the user hovered over the icon or clicked on it the contents of the text file would be in the balloon or a message box could display the contents.
For Orange I was just going to ping a DC and if it did not get a reply then I know they are not connected to the network.
I have searched for hours to find something but I cannot seem to find anything.
TIA,
Rodger

You can't do this in a service. Here is an article that will show you how to create an application like you describe., Create a System Tray Application in VB.NET[^]

Thank you for the article. I was able to edit the code to look for the file. I have a question do you know how I can have it check every 5 minutes for the file so I can change the icon and message when we have an outage?

Use a timer.

OK I am really new at VB so I need a little push . . . where would I add the timer, do I put that in the main section to call itself?

You add the timer where ever it is that you want to use it.
RodgerDJr wrote: main section to call itself
Not sure what you mean by that. You instantiate the timer with an interval that you want the timer to fire, create an event for the timer to call when the interval expires and do whatever it is that you want to do in the event. http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx[^]

Yes, it's called "a programmer".

sorry if my question is inappropriate, I'm a newbie trying to make a program, I also already have an encryption program just that I still need materials for reference, once again I'm sorry

Yes, it's called a "serarch engine". Perhaps you've heard of Google, Bing, Yahoo, ...???
It's quite easy to find if you just type "vb.net encryption tutorial" into any of these search engines.

Heres one:

I Have An Application That Prints On Remote printers
I Need To Check printer Status If Printer Is Not Ready Or Has Any Problem Like Either Its Offline Or Paper Jam Or Out Of Paper To Notify User And Abort Printing
As This An Application For A Restaurant And It Prints Order In The Kitchen So If Print Order Sent To Printer Of To Print Manager The User Will Assume That Order Is In Queue
If An error Message Is Displayed Of Any Error Then The Order Should Be Reprinted And An Error Report Is saved To Disk
Many Function On The Internet Found Is Not What I Am Looking For, As If Printing Is Offline The Status returned That Printer In Ready
Any Help On This Matter?????3

Depends on the printer-driver. Is the driver says it's ready to print, Windows will not know that there's an error, until one is thrown during the actual printing. Meaning, you'll always get the same status reported as Windows does. What have you looked at?
The "old" way of doing this is to use a special roll of paper; when the printer is "nearly" out of paper, it turns a different color, alerting the person yanking out the order that he/she should replace the paper soon. Wouldn't that be preferred for a restaurant?

You Are Correct In Some Cases
But When You Are Using Network Printer It Means Your Data Input In One Place And The Printer In Another, There IS No Way For The user To Know Or See That The Printer Is In Need of A New Paper Roll, Also if The Computer Where The printer Is Connected Went Offline And There Is And Order To Print, Technically the print Manager Assumes is printed But Actually the order Did Arrive To Destination

The Below Routine Shows If Printer Is Online Or Not It Works Perfectly
Public Function IsPrinterOnline(ByVal printerName As String) As Boolean
Dim str As String = ""
Dim online As Boolean = False
'set the scope of this search to the local machine
Dim scope As New ManagementScope(ManagementPath.DefaultPath)
'connect to the machine
scope.Connect()
'query for the ManagementObjectSearcher
Dim query As New SelectQuery("select * from Win32_Printer")
Dim m As New ManagementClass("Win32_Printer")
Dim obj As New ManagementObjectSearcher(scope, query)
'get each instance from the ManagementObjectSearcher object
Using printers As ManagementObjectCollection = m.GetInstances()
'now loop through each printer instance returned
For Each printer As ManagementObject In printers
'first make sure we got something back
If printer IsNot Nothing Then
'get the current printer name in the loop
str = printer("Name").ToString().ToLower()
'check if it matches the name provided
If str.Equals(printerName.ToLower()) Then
MessageBox.Show(printer("PrinterStatus"))
'since we found a match check it's status
If printer("WorkOffline").ToString().ToLower().Equals("true") OrElse printer("PrinterStatus").Equals(7) Then
'it's offline
online = False
MessageBox.Show(str & " " & online)
Else
'it's online
online = True
End If
End If
Else
Throw New Exception("No printers were found")
End If
Next
End Using
Return online
End Function

Hi everyone,
My update statement itself doesn't have problem but when I successfully updated the bank balance and wallet cash balance, I need those 2 value to be past to the next record's bank balance and wallet cash balance with auto Calcute with the existed enter data and saved.
For example:
Data1
Date:08/09/2012
{
Breakfast: 10
Lunch: 10
Sub: 20
}
{
Mortgage: 100
Instalment: 200
sub: 300
}
{
Total: 320
}
{
Wallet Cash: 1000 (1320-320)
}
Data2
Date:09/09/2012
{
Breakfast: 10
Lunch: 30
Sub: 20
}
{
Mortgage: 100
Instalment: 200
sub: 300
}
{
Total: 350
}
{
Wallet Cash: 650 (1000 - 350)
Let's say if I change data 1's breakfast to 90 then the sub will be 100 and the total is 400. Then 1320 - 400 = Walletcash(920). Then save.
After saving how to pass 920 to data 2's wallet cash = 920 - 350 = 570 and auto save to database. This should also be done with others data like 2 onwards till the last record.
I have coded the program to use textchange,gotfocus, and lostFocus to auto calculate when user change the textbox value. Is this way good/correct or should use sql to calculate for me.
So can some give me some ideas, example, pointer to my problem. My code is very long; so, I am reluctant to put here. If you need it tell me please.

Hmmm ... consider this.
Not knowing how your data is stored or the amount of data being stored, I'll throw an idea out to you.
Think of this like an accounting system where you have:
1) Transaction date
2) Transaction amount
3) Account Code
4) Tranasction description
In your situation, you would have 2 accounts: W-Wallet, B-Bank
Each time you perform a transaction you have to hit the right account. To get the current balance, you would sum the amounts for that account.
For example, the first two transaction would "open" your accounts:
1) Jan 1 deposit $500 to the Bank account
2) Jan 2 deposit $100 to the Wallet account.
Here are some example transactions:
1/1/2012, +500, B, Opening deposit
1/1/2012, +100, W, Opening deposit
8/9/2012, -10, W, Breakfast
8/9/2012, -10, W, Linch
8/9/2012, -100, W, Mortgage
By summing the transacitons for B or W you could determine the balance in the account at any point in time.
Maybe this would work for you.
