Hi all:

I am having a problem here:

void WordTable::addWord(string newWord, streampos pos_newWord){}; is the function signature of the function "addWord", which is a member of class "WordTable".

It receives two input arguments, one string "newWord" anther one streampos "pos_newWord".

WordTable has a private variable "table" which is of type "map". It is defined as:

map<string, vector<streampos="">> table;

When "addWord" receive two arguments, I use:

this->table.insert(make_pair(newWord, ((this->table).second).push_back(pos_newWord)));

to store the variables into a table. But I keep getting error messages telling me "second is not a member of map<_Key, _Val."

Can anyone help?

Thank you

I don't understand what you are trying to do. And your code doesn't display nicely because you didn't select the code tag.

second will only work on iterators, not on the map itself so what are you trying to do there ?

Hi:

Thank you for your reply.

Basically, what I try to do is to read from a text file and put every word and their associated positions in the file into a container, "table" of map type.
"table" is defined as:

 public:<br />
	typedef vector<streampos> OccurrenceList;<br />
private:<br />
	typedef map<string, OccurrenceList>::iterator WordIterator;<br />
	map<string, OccurrenceList> table;<br />
public:<br />
	WordTable(void);<br />
	void addWord(string word, streampos pos);

"addWord" is defined as:

void WordTable::addWord(string newWord, streampos pos_newWord)<br />
{<br />
	if (this->table.empty()) {<br />
		this->table.insert(make_pair(newWord, ((this->table).second).push_back(pos_newWord)));<br />
		}

What I try to achieve is: when a new word is read from the file, I will store the word itself (as a string) and its position in the file into "table".

Thank you

What are you trying to do here:
((this->table).second)

A map doesn't have any member called second, only iterators have. So there is something wrong there.

Also, how is your map declared (when using < and >, you need to replace them by the symbols next to the code tag). Can't you simply do something like that:
table[newWord] = pos_newWord;

And what happens if a same word appears several time in the file Confused | :confused:

Hi,
I think your are trying to add multiple occurrence of the word in a vector list in the corresponding word entry.

you may do like this,

 <br />
void WordTable::addWord(string newWord, streampos pos_newWord)<br />
{<br />
   map<string, OccurenceList>::iterator Iter;<br />
   Iter = table.find(newWord)<br />
   if (Iter == table.end())<br />
   { /* insert for the first occurrence */<br />
     OccurenceList list;<br />
     list.push_back(pos_newWord);<br />
     table.insert(make_pair(newWord, list));<br />
   }<br />
   else<br />
   {/* insert for next occurence */<br />
     Iter.second.push_back(pos_newWord);<br />
   }<br />
 .<br />
 .<br />
 .<br />

In your code I think your are also inserting multiple times the same word.

And Also you may make this more simpler if your are using multimap

<br />
<br />
multimap<string, streampos> table;<br />
then you simply needs to do <br />
table.insert(make_pair(newWord, pos_newWord));<br />

Best Regards

Hi:

This is exactly what I did, (did not use multimap()) and it worked.

Thank you very much.

Hi all.

Im trying to load data into a combo box during form load.The items Im trying to load are from a database.

Now here is my little code that gives me errors.

protected void Page_Load(object sender, EventArgs e)
{
con.ConnectionString = str;
String str1 = "Select * from Filter";
con.Open();
cm.Connection = con;
dtr = cm.ExecuteReader();
if (dtr.Read())
{
// Load FilterByKeys onto the combo box
cboExtension.Text = (dtr["FilterKey"]).ToString();<<*****Problem**** Sigh | :sigh:

lblMessage.Text = "Good. All the values are loaded";

Maybe reporting the exception text will help.
BTW, have you a FilterKey field in your table. Do you want to popolate the combo (i.e. add items) or set its text?

BTW2: wrong forum?

You will have to implement IDTExtensibility interface and in IDTExtensibility::OnConnection you have to add the Toolbar Button and Menu items.

Search for "office addin " in google you might find some article about how to create Addins.

Add this one line to your .rc file, open it in a text editor.

CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST "YourApp.exe.manifest"

YourApp.exe.manifest should be your application's manifest file.

no, because a static member has no this pointer, so it doesn't know a particular instance of the class

You have to explicitely pass such members as function arguments.
(Of course you can also pass the whole object the members belonging to).

the question was not really how to do it but is it posible to do it.

i think that if he really tries to access a data member from a static one, he definitely has a design problem, and should resise his model ; either the static member shouldn't be static, or maybe the data member access can be set static itself...

The above (IMHO) is often, but not always, true.
