PARAFORMAT2 pf2;
ZeroMemory(&pf2, sizeof(PARAFORMAT2));
pf2.dwMask = PFM_LINESPACING;
pf2.bLineSpacingRule = 4;
pf2.dyLineSpacing = 300;
SetSel(iBPos,iEPos);
    SetParaFormat(pf2);

do you set pf2.cbSize = sizeof(PARAFORMAT2) somewhere in your code after ZeroMemory call? Have you tried using dySpaceBefore and dySpaceAfter instead?

oh,i do not set pf2.cbSize = sizeof(PARAFORMAT2),but i have tried using dyspacebefore,it do not work.
