Answer 1

在delphi的win32上的progressBar为进度条，其用法要看你的事件是什么才能确定你的函数使用，但是你可以根据delphi自带的help帮助里的例子来做参考:
procedure TForm1.Button2Click(Sender: TObject);

const
// On Windows replace, myfile with a pathname such as c:\autoexec.bat
FName = 'MyFile';
var
F: File;
MyData: array[1..2048] of byte;
BytesRead: LongInt;
begin
AssignFile(F, FName);
try
Reset(F);
ProgressBar1.Max := FileSize(F);
if (ProgressBar1.Max > 10) then
ProgressBar1.Step := ProgressBar1.Max div 10
else

ProgressBar1.Step := ProgressBar1.Max;
while (ProgressBar1.Position < ProgressBar1.Max) do
begin
// read one Step size chunk of data to buffer
BlockRead(F, MyData, ProgressBar1.Step, BytesRead);
// move the ProgressBar Position using StepIt
ProgressBar1.StepIt; // move by Step amount
end;
finally;
CloseFile(F);
end;
end;
