Getting Text from an Application Running in Citrix

You can capture text from an image in a remote Citrix session.

To get text from the specified window (Win32 Form), you can use two methods by using different OCR functions:

Initialize the Picture object using the Create from Window function, and then get the text using the Get Image Text function.

This method is explained the procedure below.

Create a Picture and get the text with the Recognize Text from Control function.

You can also get text from OCR text blocks. In this case you must create a Picture and use the Get OCR Text Block function. To get the amount of OCR blocks, use the Block Count property of the Picture.

To capture text from a remote application running in a Citrix session:

1.

Open a Citrix session and run a test application.
