You are in Form1 add a control
FindDialog controls have FindDialog1 - & gt; The Options parameter frDown
FrDown parameter is///up/down to find the

CodePudding user response:

TFindOptions is a collection (Set), that is to say, TFindOptions is Sysdefs h, Set an example of the template class, if you want to know if an element is a member of the collection, you can use the Contains method:
The Options - & gt; The Contains (frDown);
Secondly, TFindDialog Options is an object, rather than a pointer, so in your RSoFindDialog to obtain when using a pointer:
RSoFindDialog (& amp; (FindDialog1 - & gt; The Options));

Best used reference in RSoFindDialog & amp; :
String RSoFindDialog (TFindOptions & amp; The Options)
{
If (Options. The Contains (frDown)
{
//down
}
The else
{
//up
}
}
