Simple VBA code for Dialog Box If Empty/No Data

[hendyhellen]

Hello again all~

Since i need to complete the simple code for my warehouse, i got stuck for this function and would like to ask the code for this issue :

I need to validate TextBox1 must be filled => if EMPTY show dialog box 'CAN'T EMPTY' and focus on textbox again
then IF QR Code not found on the Sheet Data => show dialog box 'NO BARCODE FOUND' and focus on textbox again

IF QR CODE found => the Print_Label will work and focus on textbox again for the next input

Here is the file : Scanning-LABEL

Any help is very appreciate it
Thank you so much
