Lists all values found in a drawing for a given drawing property.
struct resbuf*
ade_dwgproplist(
ade_id dwg_id,
char* property);
Returns a resbuf list or NULL.
| dwg_id | Drawing ID. |
| property | Property name. See Property Names below. |
You must release the resbuf.
The function searches the given drawing and returns a list of the values it finds for the given drawing property.

| blockname | Block names. |
| linetype | Line type names. |
| textstyle | Text style names. |
| attrib | Attribute tag names. |

The following sample gets a drawing ID from an attached drawing using ade_dwggetid then parses the resbuf returned by ade_dwgproplist() and prints a list of object data tables found in the attached drawing. Then it releases the resbuf, as required.
char* pszDwgPathName = "MYDWGS:\\SanFranMarina_BlkGrp_OD.dwg";
ade_id dwgId = ade_dwggetid (pszDwgPathName);
char* pszPropValue = "objdata";
struct resbuf* pDwgPropertyRb = ade_dwgproplist(dwgId, pszPropValue);
if(pDwgPropertyRb != NULL) {
struct resbuf* rb = pDwgPropertyRb;
while(rb != NULL) {
acutPrintf(
"\nThe current drawing set contains the following %s information: %s"
,pszPropValue, rb->resval.rstring);
rb = rb->rbnext;
}
}
else{
acutPrintf(
"\nNo information could be retrieved.");
}
acutRelRb(pDwgPropertyRb);
