Yes I thought that may be the case 
I'd seen the RAW article before on MSDN.
Unfortunately just sending the text via RAW isn't practical (as far as I can see) as I also have to print full colour bitmaps and fancy fonts.
I have the datacard SDK which I'll have to play with, it's not .NET complient tho, examples are in VB6 and use the VB6 printer object interpersed with DLL calls. Which the .NET docs say you can't do with the .NET print classes.
The only other way I can see is to automate Word or try the Crystal Reports.
Cheers
Steve.

Go with the SDK. You'll have much better luck, greater control, and no reliance on other applications. I've got a couple of DataCard printers here at work. Pretty cool little machines!

This method should work for the following manufacturers printers that allow magnetic stripe encoding via Escape codes. The snytax is slight different for each manufacture. Usually ~1 ~2 ~3 for tracks 1,2,3 respectively.
Card Printers
-------------
Eltron
Alantek
Fargo
DataCard
Victor Data Systems
*Note* This does not mean sending sending RAW data straight to the printer. The Datacard documentation explains that the print data has to be sent to the driver.
This uses the standard .net printing objects
To Encode your magstripe
'Grab the handle of the graphics object provided by the printpageeventargs
hDC = e.Graphics.GetHdc
'Set up your data
magTrack1 = "~1" & m_Card.MagTrack1
magTrack2 = "~2" & m_Card.MagTrack2
magTrack3 = "~3" & m_Card.MagTrack3
'Call the GDI ExtTextOut Routine
ExtTextOut(hDC, 10, 10, 2, Nothing, magTrack1, magTrack1.Length, Nothing)
e.Graphics.ReleaseHdc(hDC)
'Release the hdc
e.graphics.release(hDC)
Now do any other fancy graphics for your card layout and call the print event when finished. If you use a print preview you'll seen the magstripe text drawn on the screen. But it isn't printed, the printer recognises the escape codes and encodes the mag stripe.
The code for calling ExtTextOut is :-
Private Structure RECT
Public Left As Int32
Public Top As Int32
Public Right As Int32
Public Botton As Int32
End Structure
Private Declare Function ExtTextOut Lib "gdi32" Alias "ExtTextOutA" (ByVal hdc As IntPtr, _
ByVal x As Integer, ByVal y As Integer, ByVal wOptions As Integer, ByRef lpRect As RECT, _
ByVal lpString As String, ByVal nCount As Integer, ByVal lpDx As Integer) As Integer
Hope this helps someone else
Cheers
Steve.

Steve,
I know you have done this long back. I need a small help from you on this. The below line is confusing me a lot.
premiercomputers wrote: Now do any other fancy graphics for your card layout and call the print event when finished.
We get the printpageeventargs graphics handler only after calling the 'Print' method. So first we have to call Print event and in it we get the handler to send the magnetic strip text, then next we send card design etc. Isn't it?
Can you give us the code that above the 'hDC = e.Graphics.GetHdc' and Print event method implementation if possible.
Thanks
Ram

hello everyone,
im using thread timer (System.Threading.Timer) , and its working perfectly.
When i try to stop it using
MyThreadTimer.Change(System.Threading.Timeout.Infinite, System.Threading.Timeout.Infinite)
its stops , just after it finish the current task, isnt there anyway to stop it immediatly without waiting to finish its task.
Thanks in Advance

Once the timer Interval is set and the timer is running, you can't change the interval until the Timer fires its event and resets itself. The only way to change the interval, if the timer is already running, is to destroy the Timer, using Dispose, and recreate it with the new interval.

Whoops! Might have helped if a read the entire question again. I've never tried it before, but you might want to try setting the AutoResetEvent you used to create the Timer.
Dim autoEvent As New AutoResetEvent(False)
Dim timerDelegate As TimerCallback = AddressOf ...
Dim delayTime As New TimeSpan(0, 0, 1)
Dim intervalTime As New TimeSpan(0, 0, 0, 0, 250)
Dim stateTimer As Timer = New Timer( timerDelegate, autoEvent, delayTime, intervalTime)
.
.
.
autoEvent.Set()

r u sure that this is the solution!
well the problem is not in running the timer, or in calling it back...
The problem is when i stop the timer..it dont stop until it ends the current process it is doing..
like if it was sending emails for 25 persons, and i click stop, it dont stop until it send to the 25 person...just it dont callback the timer...
i want to stop the thread which the timer is executing immediatly , and not wait until its done...
Thanks in Advance

Like I said, I've never done it before. So how can I be sure that it's going to work?
You never said anything about stopping the callback method that the Timer is executing...
You'll have to rewrite your code so that this callback method checks for a flag every once in a while to tell it to stop. This has nothing to do with the Timer functionality at all!

You've asked the most generic question we've seen in a long time. What kind of control? Web Forms based or Windows Forms? What do you want this control to do?
If all you want is a tutorial on creating controls, the forums is not the place to look. There are entire books and websites dedicated to the subject. Try searching, Yahoo or Google, for "tutorial windows forms control", if that's what your looking for.

how can I get serial processor number in VB6??
|
|
|
|
|
Most systems have it turned off by default, and not all systems support a CPUID. Don't try and use it for licensing.
But, if you must, you can get the ProcessorID using WMI and the Win32_Processor class.

Hi, I wrote a windows service that starts fine when it is started manually, but when rebooting it times out(SCM 30 sec time-out). I've written some log code(to a textfile) in the Onstart() method to determine what section of this method is taking up too much time. Once again everything works fine when the service is started manually and it takes about 5 secs to start, with all the log information visible in the file. But when rebooting, it times out, before it even makes the very first entry into the logfile, which is the first thing it's suppose to do in the OnStart() method.
Can this be because the windows filesystem is not up and running yet on a reboot? Or possibly something else that my service is dependant on that didn't start yet?
Any ideas for possible("neat" or not so neat) solutions are welcome.
Thanks a lot.

is there any log files generated with scheduled task? and how can i access it remotely with vb.net? thanks
|
|
|
|

The log is kept in a simple text file at C:\WINDOWS\SchedLgU.Txt
You can get to it via normal file methods using a UNC path: \\machinename\C$\WINDOWS\SchedLgU.Txt
That is, of course, if the target machine is in the same domain as your machine. Authentication to the target machine may become an issue if your not running in a domain environment.
You'll have to come up with your own code to parse up the log file into a suitable data structure.

thanks.. what if the scheduled task didn't run at all? would it still be on the log file?
|
|
|
|

Read through the log file to understand it. The log will show that the job was launched, any error that were encountered launching the job, and the jobs return code, if any. If no attempt was ever made to launch the job, then it won't show in the log.

thanks.. yeah.. i've scanned throught the log and i traced a task that supposed to be run at a given time but it didn't show on the log.. so how can i monitor it? i mean how can i know that the task didn't attempted to start or run at all?
|
|
|
|
|
That should be obvious!  If you're monitor already knows the Task Name and it doesn't show up in the log, well, what do you think didn't happen?
