        LPSTR lpszValue
);

Remarks:

The IG_ISIS_tag_set_ascii function sets the value of the specified ASCII tag to the specified string.

Example:

The following example gets the ASCII value of the choice for IG_ISIS_TAG_DITHER whose index value is 2 (the third choice), and then sets this tag to that value:

 
Copy Code
      IG_ISIS_choice_get_ascii(hDriver, IG_ISIS_TAG_DITHER, 2, caBuffer);IG_ISIS_tag_set_ascii(hDriver, IG_ISIS_TAG_DITHER, caBuffer);
