Tipy a triky v Delphi, díl 117. - automatické vyplňování formulářů v IE

prosim o pomoc,

provadeni se zastavi na radku  "WB.Document.QueryInterface(IHTMLDocument2, iDoc1);"
myslim si, ze je to tim ze v "Document"u neni zadna hotnota (ma hdonotu "nill")

mam WindowsXP Service pack 1, Internet Explorer 6.0...Delphi 5
  dekuji za odpoved

Místo

if WB <> nil then

napis

if WB.Document <> nil then

(je to hned na tím chybovým řádkem)

%Titulek% ,ale proc proc to proste nechodi v win 9x ?? muye mi nekdo poradit pls

Budu moc vdecny

Bohužel, netuším kde by mohla být chyba. Příklad jsem zkoušel právě pod Win98SE a bez sebemenších problémů. Zkusil bych přeinstalovat Internet Explorer nejnovější verzí s SP.

Hmm tak to se omlouvam ono mi to totiž nechce chodit ani v WinME

a asi sem prisel na to kde je chyba kdyz je spostene ICQ tak mi to napise "Server RPC nelze najit " to same kdyz to ladim

ale kdyz to pustim normalne tak to chodi v poho.

Ale stejne to porad nechapu prikladam zdrojak
