Try to google for TWAIN devices, might help

Hi! I'm using TWAIN to interface with a scanner. The function DSM_Entry is accessed via a loaded DLL, TWAIN_32.DLL:
m_hTwain = LoadLibrary(_T("TWAIN_32.DLL"));
m_DSMEntryProc = (DSMENTRYPROC)GetProcAddress(m_hTwain, (LPCSTR)MAKEINTRESOURCE(1));
I then call the procedure using:
TW_UINT16 nRes =(*m_DSMEntryProc)(&m_appID, pDest, dg, dat, msg, pData);
however, some calls need for pDest to be null, (like the triplet DG_CONTROL / DAT_IDENTITY / MSG_USERSELECT for those who know TWAIN).
Unfortunately,when pDest is null for this call, an access violation appears. For other triplets, the call is OK. Has anyone encountered this before? Am I passing "NULL" the wrong way?
Thanks!

There should be some kind of documentation to explain the parameters!

please ,
how i can solve this problem ..........................
The output of this segment code must be .... ( 7 )
where base = 7 , power 3 , mod = 33
i write this code to find this formula when the number is too big
result = pow( base , power ) % mod
long MODLD( long base , long power , long mod )
{
long result = base ;
long i = power ;
if( i % 2 != 0 )
{
i-- ;
}
for( ; i > 1 ; )
{
result = ( result * result ) % mod ;
// cout<

7^3 = 343
343/33 = 10.393939393939393939393939393939
(10.393939393939393939393939393939-10)*33 = 13
Now to verify
10*33 + 13 = 343
The result should be 13 not 7.

anybody knw how to add a code that calculates the total time taken for execution...for example...
show current time before process starts...and show the end time when process done..
|
|
|
|
|
Check out the GetProcessTimes API.
Steve
|
|
|
|
|
any other ways...this one not suitable..
because..its just to show in the text file....the starting time and end time..
|
|
|
|
|
Why isn't it suitable?

1)Get the system time when you start the process
2)Get the system time when you end the process
Take the difference between the two times and what you get is the total time that your process takes to execute.
For me CAR is Challenge, Achievement and Recognition.

use GetTickCount() function.
Call the function at the begining of the process and at the end of the process.
Take the difference..
It will return the time taken by the process
Another way is to enable the profil.. in the VC++ IDE...
