VeryPDF DRM Protector allows you to fully customize how your protected PDF behaves—from pop-up messages, toolbar buttons, device binding, all the way to screen-shield protection. This guide explains how to disable all pop-up message boxes, and also includes detailed documentation on frequently used advanced parameters such as device limits, screen shield, PDF passwords, and toolbar control options.
This article is designed for administrators managing encrypted books, workbooks, training materials, and sensitive documents.
1. Why Pop-Ups Appear and How to Disable Them
By default, VeryPDF DRM Protector may display informational pop-up message boxes when a user opens a protected PDF. These messages may include:
- Number of times viewed
- Number of times printed
- Permission reminders
- Expiration information
Some organizations prefer a cleaner interface, especially for students or members. The pop-ups can be disabled using a simple option inside the DRM dashboard.
2. Step-by-Step: Disable All Pop-Up Message Boxes
Step 1 — Log in to the DRM Files Dashboard
Visit:
https://drm.verypdf.com/wp-admin/admin.php?page=VeryPDFDRMFiles
Login with your account. If you do not have one, register using your email.
Step 2 — Edit the Book Configuration
Find the book you want to modify → click Edit on the right.
Step 3 — Add the Disable Message Box Option
In the Other Options field, insert:
OtherOptions_DisableAllMessageBoxes=true
Click Save.
Step 4 — Repeat for All Books
This option is per-book. You can repeat manually for all of your books.
3. Detailed Explanation of All Advanced DRM Parameters
Below is a complete explanation of the parameters you listed. These can all be placed inside the Other Options field, each on its own line.
3.1 Device Binding (Lock to First N Devices)
Parameter:
VeryPDFDRM_LockToFirstNDevices=0
Meaning:
Controls how many devices a user is allowed to use to open the PDF.
|
Value |
Meaning |
|
0 |
No device lock (default). User can open on unlimited devices. |
|
1 |
Lock to first device only. |
|
2 |
Lock to first two devices. |
|
3+ |
Lock to the first N devices. |
Notes:
- The first device(s) used by the user will be remembered automatically.
- This is useful for preventing password sharing among students.
- You can increase the number anytime later, but decreasing may lock out existing users.
3.2 User ID (Do Not Modify)
Parameter:
UserIDNumber=0
Meaning:
- Internal unique user ID generated by the DRM system.
- Used for authentication and access control.
- Do not change this value, otherwise the user may lose access.
3.3 PDF Passwords (Do Not Modify)
Parameters:
UserPassword=XXXXXXXXXXXXXXXXX
OwnerPassword=XXXXXXXXXXXXXXXXX
Meaning:
- These passwords are automatically generated by VeryPDF DRM Protector.
- They are used internally by the encryption engine.
- Do not change or delete these passwords, otherwise the encrypted file may not reopen.
Important Reminder
These passwords are not visible to end users.
They are internal and required for the PDF engine to decrypt the file.
3.4 Screen Shield (Optional Visual Protection)
Parameter:
VeryPDFDRM_ScreenShield=0
Meaning:
Controls the screen shield coverage percentage (for anti-screenshot protection).
|
Value |
Effect |
|
0 |
No screen shield (default). |
|
1–50 |
Show a shield covering 1%–50% of the visible page. |
Use Cases:
- Preventing HD screen recording
- Making piracy screenshots useless
- Protecting high-value content (training materials, exam papers, etc.)
Notes:
Higher percentage = stronger protection but more visual obstruction.
3.5 Toolbar Button Visibility Control
These parameters hide or show buttons in the online PDF viewer toolbar.
Examples:
ToolbarButton_FullScreen=hide
ToolbarButton_OpenFile=hide
ToolbarButton_Print=hide
ToolbarButton_Download=hide
ToolbarButton_ViewBookmark=show
ToolbarButton_editorHighlight=show
ToolbarButton_editorFreeText=show
