Handling Windows Dialogs Using Selenium Part 1

The API:

The API is small and simple. It contains two Classes that will do the work for us. :)

Introducing the two imp Classes,

WindowHandler - Responsible for all the operations on Window Objects
WindowElement - Represents an Element (Object) in/or a Window

The API uses JACOB to communicate with a DLL component called ATU_WindowsHandler.dll (Developed as a part of Project) which communicates with the windows objects for performing automation .

The DLL requires Microsoft .NET  v4  to be installed in the machine. Download .NET v4 From Here
After installing the .NET Framework, follow the below steps for registering the DLL.

• Open CMD prompt with Admin Rights
• Change the directory in CMD prompt where the DLL file is present
• Type the below cmd without quotes and hit Enter Key

If the DLL is in the C Drive then

for 32 Bit (x86) OS:

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm C:\ATU_WindowsHandler.dll /codebase"


for 64 Bit (x64) OS:

"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm C:\ATU_WindowsHandler.dll /codebase"

Notice that the path should have "Framework64"  folder for 64 bit .Net reference whereas "Framework" for 32 bit.



You should get a message as shown in the below screenshot.

As you can see, in my machine, the DLL file is located in "F" drive, after the CMD operation, the DLL is registered successfully.

Note: Sometimes, The DLL may not get registered due to security concerns 

to resolve this, try the below approach: 

• Download the ATU WindowsHandler dll zip file. 
• Right click on the zip file
• Click on "Properties"
• Click on the "Unblock" button.
• Click on "Apply" button
• Click on "OK" button
• Extract the zip file
• Register using the same command

After this, the DLL should get Registered.
