is possible user form just only lock the current workbook?

[Step01]

i have open 2 excel but when i run the user form it will block both content , i just want to block current workbook content only.

I think I understand what you mean, and if so, I suspect it is because the user form is a modal dialog (a bit like the one that comes up when you launch PowerQuery). This means that you can only interact with that window in Excel whilst ever it's open, and I doubt, therefore, that there is a workaround, as I believe this is a Windows level feature.

What do you mean by 'block'.

Try setting your userform ShowModal modal property to false. A macro can selectively do stuff, like switching on sheet protection' with one workbook but not the other. If your workbook has macros that address both workbooks then change it so that it only addresses one of them. Difficult to comment further without seeing the workbook.
