Hi Irosenth,

Shall we use ASCab to retreive the paramters needed and store the parameters needed for the dialog box.

Kindly clear me i'm going in the right path?

Hi Axel Bangert,

Send keys wont work if the active desktop is locked up.

i have used sendmessage instead but i succeded one click event after that i not able to reach the end.

HWND papercapturedialog=FindWindow(NULL, "Recognize Text");

SendMessage(papercapturedialog, BM_CLICK, 0, 0);

after this if i capture Recognize Text - Settings

i am not able to send any window param for combo box.Kindly clear me where i went wrong?

i know my problem but i can fix it

the problem is when i execute Command i get the active document

AVCommandStatus status =AVCommandExecute (cmd);

AVDoc avDoc = AVAppGetActiveDoc();

PDDoc pDDoc = AVDocGetPDDoc(avDoc);

when i minimize the acrobat

the AVAppGetActiveDoc(); --> return null

is there any way to get the returned Document from the command

or avoid this error

thanks

Hi,

with the sendKeys we can set ClearScan for example like that:

ACCB1 void ACCB2 MyPluginCommand(void *clientData)
{
    PDDoc pddoc;
    AVDoc avDoc = AVAppGetActiveDoc();
    PDDoc pdDoc = AVDocGetPDDoc (avDoc);
    ASAtom cmdName;
    AVCommand cmd;
    cmdName = ASAtomFromString ("PaperCapture");
    cmd = AVCommandNew (cmdName);
   //SendKeys to set -> clearScan
    keybd_event(VK_TAB ,0x8f ,0 , 0);              //TAB
    keybd_event(VK_TAB ,0x8f , KEYEVENTF_KEYUP, 0);
    keybd_event(VK_DOWN , 0, 0, 0);              //Down
    keybd_event(VK_DOWN , 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_DOWN , 0, 0, 0);              //Down -> clearScan
    keybd_event(VK_DOWN , 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_TAB, 0x8f, 0 , 0);             //TAB
    keybd_event(VK_TAB ,0x8f , KEYEVENTF_KEYUP, 0);
    keybd_event(VK_TAB, 0x8f, 0 , 0);             //TAB
    keybd_event(VK_TAB ,0x8f , KEYEVENTF_KEYUP, 0);
    keybd_event(0x0D, 0, 0, 0);                       //ENTER
    AVCommandStatus status = AVCommandExecute (cmd);
    keybd_event(0x0D, 0, KEYEVENTF_KEYUP, 0);
    return;
}

But its not good coding, as I mentioned before. And in Adobe 9 and 10 you can see, that

there must be parameters that can be used ( see create pdf -> from scanner -> configure

settings ).

For me the OCR side is not so important, for I'm constructing a V-Scanner - its only for

testing, wheather the velocity of the OCR corresponds to the speed of the scanning process,

or not.The OCR can be done such as the final user likes and as he buys the software .

Hi SDK,

normally you only use SendKey from C# or VB or Java but not from C++. But your

idea is not bad to call it directly from the plugin. If you want to use SendKey from

C++ take a look at this explanation here in CodeProject.

What concerns 'Chief Ironside': In the Header Files I found nowhere the parameters

for 'PaperCapture'. Mr. Ironside you first repeated to say that it is documented in the

SDK - please tell us, where 'PaperCapture' is exactly (?link?) documented in

the Acrobat SDK?

Hi SDK

in Java that is something like that:

public void keyPressed(KeyEvent e)

{

int key = e.getKeyCode();

if (key == KeyEvent.VK_ENTER)

{

System.out.println("ENTER pressed");

}

You don't mention HOW you are calling Acrobat, so we can't really help you

PaperCapture.api is the old name for the OCR capabilities in Acrobat implemented via a plugin. There is no access to it from VB/C#.

So there is no way to run OCR programmatically in VB.net or C#.net...?

In the Acrobat SDK there is documentation and samples around the AVCommand set of APIs.

Just tell me how to add these API's to me .net code..give some samples..
