function DelDirectory(const Source: string): boolean;
var
fo: TSHFILEOPSTRUCT;
begin
FillChar(fo, SizeOf(fo), 0);
with fo do
begin
Wnd := 0;
wFunc := FO_DELETE;
pFrom := PChar(source+#0);
pTo := '';
fFlags := FOF_NOCONFIRMATION + FOF_SILENT+FOF_ALLOWUNDO+FOF_NOERRORUI;
fAnyOperationsAborted:=False;
end;
Result := (SHFileOperation(fo) = 0);
end;
下面语句为什么老是提示“Access violation at address 00420ef3 in module xxx.exe. Read of address 00000000 process stopped”?但是如果没有最后两行,却没有错误?
wjj:= 'c:\test';
if directoryexists(wjj) then
DelDirectory(kswjj); if not directoryexists(kswjj) then
CreateDir(kswjj);
