ADF Automatic Document Feeder

[Deficiency]

Hello!

I have a Question: Can some look at these code lines and say me what i have done wrong?

//Document Feeder

TW_CAPABILITY twCapability;

TW_INT16 rc;

TW_UINT32 NumberOfItems;

twCapability.Cap = CAP_FEEDERENABLED; //Insert Capability of Interest

twCapability.ConType = TWON_ONEVALUE;



pTW_ONEVALUE pvalOneValue;

TW_BOOL valueBool = true;;

twCapability.hContainer = GlobalAlloc(GHND, sizeof(TW_ONEVALUE));

pvalOneValue = (pTW_ONEVALUE)GlobalLock(twCapability.hContainer);



pvalOneValue->ItemType = TWTY_BOOL;

pvalOneValue->Item = valueBool;

GlobalUnlock(twCapability.hContainer);



//

MSG_SET

rc = (*g_pDSM_Entry)(&g_AppID,

&g_SrcID,

DG_CONTROL,

DAT_CAPABILITY,

MSG_SET,

(TW_MEMREF)&twCapability);

GlobalFree(twCapability.hContainer);

switch (rc)

{

case TWRC_SUCCESS:



//Capability's Current or Available value was set as specified



case TWRC_CHECKSTATUS:

//The Source matched the specified value(s) as closely as possible

//Do a MSG_GET to determine the settings made



case TWRC_FAILURE:

//Check the Condition Code for more information



default:

break;



}

I have a network scanner and i connect via Netzwork Twain on it. If i do not include this lines of code i can display the Picture and they i can save it as BMP. The code for the Display and save are both with Twain.

But when i include the lines above it doesn´t work anymore!
And i realy don´t know what i do wrong?

By the way, the code is in the function openDS()

thx a lot
