Example:

	Copy Code
HIG_ARTX_PAGE hArtPage = NULL; //ArtX page handle HIG_ARTX_MARK hMark; //Annotation handle //Create new ArtX page IG_ARTX_page_create(&hArtPage); //load annotation data from file IG_ARTX_page_load_file(hArtPage, "ArtXSampleData.xml", 1, TRUE); //Find first annotation on ArtX page IG_ARTX_page_mark_first(hArtPage, &hMark); if(hMark) { LPAT_VOID lpData = NULL; //pointer to the user data to be acquired //Get user data associated with hMark annotation IG_ARTX_mark_user_data_get(hMark, &lpData); if(lpData != NULL) { //Display the user data (zero terminated string) in a message box MessageBoxA(NULL, (LPSTR)lpData, "UserData associated", 0); } }

Copy Code

HIG_ARTX_PAGE hArtPage = NULL; //ArtX page handle
HIG_ARTX_MARK hMark; //Annotation handle

//Create new ArtX page
IG_ARTX_page_create(&hArtPage);

//load annotation data from file
IG_ARTX_page_load_file(hArtPage, "ArtXSampleData.xml", 1, TRUE);

//Find first annotation on ArtX page
IG_ARTX_page_mark_first(hArtPage, &hMark);
if(hMark)
{
    LPAT_VOID lpData = NULL; //pointer to the user data to be acquired
    //Get user data associated with hMark annotation
    IG_ARTX_mark_user_data_get(hMark, &lpData);
    if(lpData != NULL)
    {
        //Display the user data (zero terminated string) in a message box
        MessageBoxA(NULL, (LPSTR)lpData, "UserData associated", 0);
    }
}

Remarks:

The User Data that can be associated with annotation is a zero-terminated character string.

The lpData parameter receives a pointer to internal copy of the string previously associated with hMark annotation by an IG_ARTX_mark_user_data_set() call.

These functions only work with zero-terminated character strings and not with arbitrary pointers. When ArtX marks are saved to a file, user data is saved as well.
