invoking progressbar in another cpp file

[sivamoorthy]

how to use a progressbar in a one cpp file but defined in another header file.
the function in which i am using is a static member function. how to use the progressbar inside the function


code:
file name : flash.cpp
void CFlasher::OnStartDownload (void *pDublicate)
{
bValueRet = DeviceIoControl (hHandle, \
(DWORD) IOCTL_SCUSBDFU_DETACH, NULL, \
0, NULL, 0, &dwBytesReturned, NULL);

HERE I HAVE TO USE THE PROGRESSBAR

}
file name : form.h
progressbar is defined in this header file

please kindly give me the solution for this

Just #include the header file that has the function prototype of the functions you want to call. Then make sure both .cpp files are compiled and linked.

i already included the #include form.h in the .cpp file where i want to use the progressbar.both compiled and linked.

What's in the form.h?

Usually, you incude the header file at the beginning of the .cpp file and then call functions that are prototyped in that header file later on.

Simply including the header file at a preciose location will not call any functions.
