Question

Determine if same document is opened

Hello,

I have developed a plugin to open a document from the document path received from external program.

Is there any way to avoid reloading the document when same document is opened twice.

Here is my code snippet:

ACCB1 void ACCB2 OpenDocument()
{
AVDoc avDoc = AVAppGetActiveDoc();
PDDoc pdDoc = AVDocGetPDDoc(avDoc);
char filePath[256];
GetPrivateProfileString("OpenFile", "filePath", "", filePath, 256, iniFilePath);
ASAtom pathType = ASAtomFromString("Cstring");
//Create an ASText object
ASText titleText = ASTextNew();
ASTextSetPDText(titleText, "This PDF was opened by using the Acrobat SDK");
//Create an ASPathName object
ASFileSys fileSys = ASGetDefaultFileSysForPath(pathType, filePath);
ASPathName pathName = ASFileSysCreatePathName(fileSys, pathType, filePath, NULL);
//Open the PDF file
AVDoc myDoc = AVDocOpenFromFile(pathName, fileSys,NULL);
//Do some clean up
ASFileSysReleasePath(fileSys, pathName);
ASTextDestroy(titleText);
}

Thanks

But what if the user has opened a document themselves? Including the possibility of browser integration?

Your checking code looks ok but you do not say how you call it. Do you enumerate all open AVDoc?

No. I do not have to enumerate all open AVDoc.

At any time, there will be only one document opened in the Acrobat as I don't want to open new window for each document.

is there a problem (edited) with my solution in your previous similar question? Seems that it will work.

It shouldn't open twice. What do you see?

I can see the reloading of the document if the document is same.

Hello,

I did some workaround on this.

Before opening any new document, I am checking the path of the document that is already opened like this:

ASFile pdffile = PDDocGetFile(pdDoc);

ASFileSys fileSys = ASFileGetFileSys(pdffile);

ASPathName pathName = ASFileAcquirePathName(pdffile);

CString strDocPath = ASFileSysDisplayStringFromPath(fileSys, pathName);

And if so, I do nothing otherwise I open the other document.

If there is any glitch, please let me know.

Thanks.
