Hi, Then i must be confused about what it is hfindex are doing and where they show up in the tree. Could you explain / how to use format?

You'll have to format the presentation of your data completely. proto_tree_add_uint_format(proto_tree *tree, int hfindex, tvbuff_t *tvb, gint start, gint length, guint32 value, const char *format, ...) tree: the tree you want to add to; hfindex: headerfield index of the definition of the header field. Applicable for filtering; tvb: the TVB you work from; start: start offset in TVB, maybe 0 if N/A; length: length of data in TVB, maybe 0 if N/A; value: value you want to be able to filter with; format: printf format string; ...: any format string parameters.

But also, for "id". It takes an int, but what if i want to put a different string there? I want to be able to include my own string for output that isn't in a static const value_string. I will be return data from a function from a loaded dll. And just something like: >> >> proto_tree_add_uint(tree, "Test: ", tvb, 0, 0, 7) >> >> or >> >> proto_tree_add_uint(tree, testfunction(), tvb, 0, 0, 7) >> >> where testfunction() would return a char * or something of the sort. Is there an easy way to do something like this? >> >> Greg
