: You can call a function like QRCodegenBarcode to return a StdPicture object. Example :
Now, the new scanner was a USB device that emulated a keyboard. When Martin scanned a test QR code—a tiny sticker from a shipping crate—the text box filled with a string that looked like nonsense:
Public Declare Function FastQRCodeLib_CreateQRCodeLib Lib "qrcodelib.dll" ( _ ByVal TextData As String, _ ByVal SavePath As String, _ ByVal ImageSize As Long, _ ByVal CorrectionLevel As Long) As Long Use code with caution. 2. Writing the Generation Code

He double-clicked cmdGenerate .
If you have a COM-compatible SDK installed, a basic implementation looks like this:
