Thread: More PROGRESSBAR help!(SIMPLE!)

Here's some code:

LPCH pch;
LPCH pchTemp;

switch (message) /* handle the messages */
{
case WM_CREATE:
InitCommonControls();

hFile = CreateFile("C:/Starfield/NetStudio 1.5/NetStudio 1.5.exe", GENERIC_READ, FILE_SHARE_READ, NULL,
OPEN_EXISTING, NULL, NULL);

cb=GetFileSize(hFile, (LPDWORD) NULL);

HWND pb;

pb=CreateWindowEx(
WS_EX_CLIENTEDGE,
PROGRESS_CLASS,
"",
PBS_SMOOTH | WS_CHILD | WS_VISIBLE,
0, 0,
400, 20,
hwnd,
0,
0,
0
);

SendMessage(pb, PBM_SETBARCOLOR, 0, RGB(20,30,150));
SendMessage(pb, PBM_SETRANGE, (WPARAM)0, (LPARAM)MAKELPARAM(0, 100));
SendMessage(pb, PBM_SETSTEP, (WPARAM)1, (LPARAM)0);

pch = (LPCH) LocalAlloc(LPTR, sizeof(char) * 2048);
pchTmp = pch;

do
{
ReadFile(hFile, pchTemp, sizeof(char) * 2048, &cb, (LPOVERLAPPED) NULL);

SendMessage(pb, PBM_STEPIT, 0, 0);
} while(cb);

CloseHandle((HANDLE)hFile);
break;


When I run the program, it only progresses for about 1 block on the bar. How do I make 1 block for every 1 percent read and progress the bar?

NOTE: Some code came from MSDN and NetStudio 1.5.exe is a program I made!

Come on this should be easy for a published pro like you! (Or is it easier for you to get me to tell you how?)

You have the file size, now find the ratio out of 100 (eg a percent ratio) for the read size (cb).
Step the bar this amount of times.

So if the file is 100Kb and you read 2Kb per read, how many TIMES to you have to send the step msg?

//edit
I also send this msg to ensure the progress is at the begining

SendMessage( GetDlgItem(hhwnd,IDC_PROG), PBM_SETPOS, (WPARAM) 0,(LPARAM)0);

Can you tell me how to get a percent ratio?
