The cpMin member of FINDTEXTEX.chrg always specifies the starting-point of the search, and cpMax specifies the end point. When searching backward, cpMin must be equal to or greater than cpMax. When searching forward, a value of –1 in cpMax extends the search range to the end of the text.
cpMin은 항상 시작점이셈.. cpMax는 끝점이고, 뒤로 검색할땐 cpMin이 cpMax랑 같거나 커야됨!

FR_DOWN
Microsoft Rich Edit 2.0 and later: If set, the search is forward from FINDTEXTEX.chrg.cpMin; if not set, the search is backward from FINDTEXTEX.chrg.cpMin.
FR_DOWN하면 cpMin앞으로 검색하게됨여
없으면 cpMin뒤로하구여

FINDTEXTEX ftex;
ftex.lpstrText = target;
ftex.chrg.cpMin = 10;
ftex.chrg.cpMax = 0;

LRESULT lr = SendMessage(hRich, EM_FINDTEXTEX, NULL, (LPARAM) &ftex); // 널자리에 일부러 딴거넣어도 위로 검색안됨

if (lr >= 0)
{
LRESULT lr1 = SendMessage(hRich, EM_EXSETSEL, 0, (LPARAM)&ftex.chrgText);

SendMessage(hRich, EM_HIDESELECTION, (LPARAM)FALSE, 0);
return lr1;
}
SendMessage(hRich, EM_HIDESELECTION, (LPARAM)TRUE, 0);
return FALSE;

역검색 FR_DOWN그냥 없으면 될줄알았는데 안되요 도와주세여...
