Handle reading multiple barcode from multiple barcode device

i want to read barcode from multiple barcode scanner devices at a point of time in a text box control ,.should be reading one scanner at a time till then other scanner should be in a queue or waiting ,searched a lot didnt get any satisfying solution ,can you please let me know .

This depends on where you already have the hardware devices connected and you just want to sync the reading processes between them, or you only have the scanned barcode images and you want to read them one after the other?
Can you provide more details about how exactly do you receive the multiple barcodes? And how exactly the multiple barcode scanners are connected?
The following forum post contains useful information about detecting distinct inputs from the barcode scanners:

And alternative solution would be scanning all barcode images at once, save them to a shared folder so that each scanner saves the scanned image, and then each 30 minutes or less, check all images in this folder and pass them to a software barcode engine to recognize the barcodes and save each result to an independent text file. And move each recognized barcode image to a separate folder that contains all the recognized images.
For example, you can use the .NET barcode engine from LEADTOOLS (1D and 2D) as described in the following article:

I hope this helps.
