问题 I am wanting to set up an excel spreadsheet for data entry with a barcode scanner. The barcode scanner sends the barcode then a tab OR an enter key depending how its programmed. Basically I want to set up an excel sheet that we can scan 6 barcodes for each item, with the scanner tabbing to the next column each time, then when it reaches the 6th column the next tab will make it move to a new line for the next product. I hope this makes sense. It can be done in MS word... e.g if you create a

问题 I have bar code scanner. Sometimes user wants to search items by bar code. But he is lazy enough and doens't want to use mouse at all to click on input. Scanner usually inputs from 8 to 13 symbols very fast, no human types so fast. It would be perfect solution to (1)detect extremely input and if no input element on the page has focus (2) then to select the input with certain class , fill it with content from scanner and start searching. Second stage is non-issue. I 've no idea how to start

问题 I've been using a camera BarcodeScanner (Microsoft's BarcodeScanner API) for 3 weeks now in my UWP application. It's working well but sometimes, the preview window of the barcode is not opening and the BarcodeScanner is not turning on. When I figured this out, I took my app in debug mode to see where was the problem and if they were some exceptions thrown. Here's how I'm initializing the BarcodeScanner : public async Task ClaimScannerAsync() { string selector = Windows.Devices.PointOfService

问题 i just got a bar code reader : Barcode Reader how can i read the data from this gadget with C# ? 回答1: Typically, barcode readers work as a standard keyboard. When you scan a barcode, the appropriate information will be "typed" just as if it were a keyboard entry. You just need to author your software to handle the entry information as normal key data. 回答2: A barcode scanner can operate in two modes as Reed says like a keyboard or as a serial device. To get it into the latter you will need to

问题 I've recently been asked to develop an application for the Motorola MK4000, an all-in-one device with a built-in barcode scanner. It runs Windows CE and supports VB.Net. I've never written an application for Windows CE, nor using a barcode scanner. I'm familiar with VB.NET so I'm confident I can figure this out, but I was hoping someone could point me to some resources on how to use the barcode scanner with possibly some example code of how to detect it and read data from it. Thanks. 回答1:

问题 I am trying to generating IDAutomationHC39M for number 50 or 51 the barcode for that gets generated but on scanning I am not able to get the Detail number for that.
