I thought I already did. Use:

books.Open("c:\\book1.txt",

           vtFalse, 
           COleVariant(6L),

           vtOptional, 
           vtFalse,
           vtOptional,
           vtOptional);

If you still need to use OpenText(), try:

books.OpenText("c:\\book1.txt",
               COleVariant(1L),
               COleVariant(1L),
               COleVariant(1L),
               -4142,
               vtFalse,
               vtFalse,
               vtFalse,
               vtFalse,
               vtTrue,
               vtFalse,
               vtOptional,
               vtOptional,
               vtOptional,
               vtOptional,
               vtOptional,
               vtOptional,
               vtOptional);

You should not open a .txt file like this. Because there is no need for any automation in this.

You use this...

CStdioFile myFile;
CFileException fileException;

myFile.Open( "F:\\test.txt", CFile::modeCreate | CFile::modeReadWrite|CFile::modeNoTruncate, &fileException );

myFile.Write(const void* lpBuf, UINT nCount);
myFile.close();

Thanks and Regards.

Hi, I need to create a Setup.exe of mi app. I have a problem.

What I have done is that:

Build->Configuration->Select Release

Compile, build

There was an error:

fatal error C1083: Cannot open precompiled header file: 'Release/TMB.pch': No such file or directory

I changed the settings and selected
Precompiled Headers->Not using precompiled headers

But now it says:

error LNK2001: unresolved external symbol _dbdead
error LNK2001: unresolved external symbol ...
error LNK2001: unresolved external symbol ...
error LNK2001: unresolved external symbol ...

about 30 times.

What should I do?

Time to come clean...

Hi,

hope this might help

While programming in VC++ using dblibrary for c I too got some Unresolved externals error.
I don't know much about your IDE,but here's what I did in VC++

1. clean your solution: Build > Clean Solution
2. found out the name of the required lib file
3. Project > settings> links tab , added the .lib file name to list of Object/Library modules

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 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?
