Hi

When I use RegQueryValue() to get the string to run an executable to which I wish to pass a parameter why must I remove the last character on the return value?

In the following sample program. After the first call to WordPad no file is opened, however on the second call the file opens as expected.

Thanks,

Vytas

RegQueryValue( nHandle, "WordPad.exe", @cValue )

MsgInfo( cValue )

WaitRun(cValue + " testreg.prg")
WaitRun(SUBSTR(cValue,1,(LEN(cValue)-1)) + " testreg.prg")

RegCloseKey( nHandle )

MsgAlert( "Can't open this key" )

return nil

procedure AppSys // XBase++ requirement

return

Because the value returned is a zero-terminated string.
