How can I use the barcode in my Program?
I had some question about barcode!
In my program how can I print barcode with Standard code39
If you know a free font or component and you test it please introduce me
And how can get the data from barcode reader (such as keyboard, USB, Serial-port) and display in the text box (Please give me a source not component)![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

It will depend, but most barcode readers offer an API that returns the code as a string.

yes, the most barcode writters receive an string and then generate the barcode, then only must send this control to printer, you can draw this control in a printer o another method should it work.

I suggest you to focuse on how to create and use classes in vb.net.

Why don't you use tab control? Check the toolbox!
How did you create the tabs?

Hai i have migrated the vb code into vb.net.When i was migrating i found that copy memory function cant able to work it seems.
i am using the function
Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef hpDest As any, ByVal hpSource As any, ByVal nBytes As Integer)
and call the function inside form1.show
Call CopyMemory(arrBarCodeInformation(0), ptrBarCodeInfo, size_Renamed)
i have declared
Public arrBarCodeInformation() As BarCodeInformation
Public Structure BarCodeInformation
Dim tRegionRect As rect
Dim dwBarType As Integer
Dim fOrientation As Single
Dim lDecodeStatus As Integer
Dim lNoOfCharacters As Integer
Dim lpbDecodByteArray As Integer
Dim lReserved As Integer
Dim hReserved As Integer
End Structure
using this i want to copy the memory value from integer value into the structure variable.how can it been done.tell me the syntax are any function to copy memory

You're not listening. You do NOT need CopyMemory to do this. You need to marshal this structure to your function properly. This is not done the same way it was under VB6.
If you created and instance of this structure in your code and just want to assign a value to one of it's members, then all you have to do is something like this:
arrBarCodeInformation(0).dwBarType = 42
Other than that, you haven't described what your doing with this stuff, nor have you posted any of the code you're trying to convert to show us what you want it to do.

Hi All,
How do I state where abouts on the page I want a msgbox to appear?
Also is it possible to make it topmost (like the way you can make forms top most).
Thanks in advance

Popular question This was asked just a few posts down. I believe you can't position the msgbox. You could make your own message box though. All it is is a form. It's little more work to re-invent the wheel but if you want to place it then you'll need to create your own. It will also allow you to make it topmost.

Before telling you how to do it, have you searched for an answer?

I am using Background worker class in my application to retrieve the some files in system but filenames are not populated in grid.......
Please Help

The background worker and the UI run on separate threads. In order to send results to the UI from the backgroundworker you can use the ReportProgress method of the background worker. In the UI you will need to handle this event to add new items to the grid.
Or you can return the results in the RunWorkerCompleted method than have the UI update the grid.

Hi
I want to write a realtime application - one window (running in the main thread) will talk to the outside world and get stock prices - then there could be any number of other chart windows each running in their own threads. When a new price comes into the main window I want to raise an event (new price) that all the other windows will pick up and if they are interested in it plot the value. So How do I raise an event that any number of other threads will pick up and process.
Any help greatly appreciated
Thanks
Paul

I am trying to add a line of text to a log file over HTTPS and after trying lots of different methods I either get a 405 error (method not valid) if I use POST or if I use PUT it simply overwrites the file rather than appending. I am literally pulling my hair out with this. Any help would be much appreciated. My code at the moment is:
Dim client As New System.Net.WebClient()
client.Credentials = New System.Net.NetworkCredential("XXX", "YYY")
client.UploadString("https://sbs.expwconsulting.com/Event generator/Logs/checks.txt", "PUT", "Test")
