I want to make a progress bar start off hidden, then when a user clicks on the "proceed button" the progress bar appears:

I tried this but it doesnt work ?

invoke SendDlgItemMessage, [hwnd],IDB_PROGRESS,PBM_SETSTATE,WS_VISIBLE,0

Can anyone please help ?

Use this.

Code:

ShowWindow, hwnd, SW_HIDE

You have misunderstood my question, I dont want to "show a window", I want to enable/show a progress bar, on a dialog window.

besides, how would "SW_HIDE" show a dialog element ????

I want to show a dialog item and this will involve the function

SendDlgItemMessage

I just need to know the correct parameters.

Its a shame Microsoft are so piss-poor at documenting there API

It seems like you are new to Win32.

Look up PBM_SETSTATE message:

Quote:

wParam
State of the progress bar that is being set. One of the following values.
PBST_NORMAL
In progress.

PBST_ERROR
Error.

PBST_PAUSED
Paused.

Notice WS_VISIBLE is not an option.

Try GetDlgItem then ShowWindow

NO I have already got the progress bar hidden on creation,

dialogitem "msctls_progress32","Progress1",ID_PROGRESS,120,145,174,9,\
WS_DISABLED,0
User hits button then I want to make the progressbar visible.

I have already tried,

invoke SendDlgItemMessage,[hwnd],ID_PROGRESS,PBM_SETSTATE,WS_VISIBLE,0
but its doesnt work, I have set the wrong parameters.

invoke GetDlgItem,[hwnd],ID_PROGRESS
invoke ShowWindow,eax,1

WORKS !!! COOL BANANA'S

All dialog elements are HWNDs, so all HWND can do (using API) -- dialog elements can do too.

Yes, there is nothing special about dialog elements. They are just standard windows that can be manipulated using standard window functions. A dialog box is just a convenient container to hold all the various buttons, labels and other windows together in one place.
