PRB: _VFP.DataToClip() Only Reads DataSession 1 (280309)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0
  • Microsoft Visual FoxPro for Windows 5.0a
  • Microsoft Visual FoxPro for Windows 6.0
This article was previously published under Q280309

SYMPTOMS

The DataToClip() method is not able to access data in a private data session.

CAUSE

Because DataToClip is associated with the Application Object (_VFP), it only has access to the data in the Object's DataSession, which is DataSession 1.

RESOLUTION

One workaround is to write a routine that converts each field to character type (the Transform() function does this easily in Visual FoxPro 6.0), concatenates the information, and stores it to the _CLIPTEXT variable.

MORE INFORMATION

Steps to Reproduce Behavior

To display this behavior, paste the following code in a .prg file and run it: 
CLOSE DATA ALL
_CLIPTEXT = ""

loForm = CREATEOBJECT("MyDSForm")
MESSAGEBOX(_CLIPTEXT)

DEFINE CLASS MyDSForm AS form
   DataSession = 2
   
   PROCEDURE Init
      USE HOME() + "labels"
      
      *!* Because we did "CLOSE DATA ALL" at the top of the program,
      *!* there is no data in the default session to read.
      _VFP.DataToClip()
      
      *!* If you uncomment the next line, you will receive an error.
      *!*   _VFP.DataToClip("labels", 100)
   ENDproc
ENDdefine
