hi,

i want to use the twain dll (click here to download the dll) to scan a image from my scanner to a file.

i found some visual basic (.net) scripts but i can't find out how to do it in AutoIt

the scripts i found:

can someone find out what i have to put in 

DllCall("dll","return type","function",["type1","param1",["type n", "param n"]])

Thanks,

Thanks for that, just what I needed.

edit: wtf? I glanced at the header file and got bombarded with a lot of structs and defines!

Anyone else wanna figure this out, I'll provide only the necessary lines of code:

/****************************************************************************

 ****************************************************************************/

/**********************************************************************
 * Function: DSM_Entry, the only entry point into the Data Source Manager.
 *
 * Parameters:
 *  pOrigin Identifies the source module of the message. This could
 *        identify an Application, a Source, or the Source Manager.
 *
 *  pDest   Identifies the destination module for the message.
 *        This could identify an application or a data source.
 *        If this is NULL, the message goes to the Source Manager.
 *
 *  DG    The Data Group. 
 *        Example: DG_IMAGE.
 *
 *  DAT  The Data Attribute Type.
 *        Example: DAT_IMAGEMEMXFER.
 *  
 *  MSG  The message.  Messages are interpreted by the destination module
 *        with respect to the Data Group and the Data Attribute Type.  
 *        Example: MSG_GET.
 *
 *  pData   A pointer to the data structure or variable identified 
 *        by the Data Attribute Type.
 *        Example: (TW_MEMREF)&ImageMemXfer
 *                 where ImageMemXfer is a TW_IMAGEMEMXFER structure.
 *                  
 * Returns:
 *  ReturnCode
 *       Example: TWRC_SUCCESS.

Sorry, but I can see no other functions other than 2 entry points. Are you sure that this is the header file?

no i don't.

i don't know nothing about dll or the header files

but thanks for what you have done now.

but what the main point of this topic is to scan an image with the scanner. what i thought is to use a dll (the twain dll) but there are maybe other ways.

any suggestions?
