I just said that what you did is almost the same as the code in my ASP.NET book. The code *should* work, but obviously isn't.
Its starting to get that time though, so I'll have to take a look at it whenever I get up out of bed :-P

(In VC6.0,using MFC & ADO)
I wrote a application based on MicroSoft Access.To let users use my application more easily,i want to save them from setting a DSN in Control Panel ODBC Administrator by themselves.Now suppose i have a Access file called List.mdb located in C:\,it contains just one table called Toys,and i created a ADO smart pointer in my code:
_ConnectionPtr m_pConnection;
Then,what the ConnectionString of m_pConnection shall look like? Or there's some other good method?
Thanks Much
God blessing me...

Thank you.It's OK now
But why does it work only when i cut the path,just write: L"...;Data Source=list.mdb;" ?Otherwise,it will append the path where the application locate,then cause a "can't find file" error.

I have DataAdapter and DataSet,my dataadapter string is something like this:
"SELECT * FROM TABLE",and I fill dataset with this dataadapter,and I bound Datgrid to it and it's ok.
Now after this I want to set a filter for the recorsets that datagrid show.Can I use those dataadapter and dataset and set the filter in the way that I don't know it,
or I HAVE TO fill dataadapter and dataset from the beginning with new SQL statement?

To filter your table:
1) Get the DataView from the appropiate table.
MyTable.DefaultView //this is a property of the table.
2) Set the Filter.
MyTable.DefaultView.RowFilter = "Name = 'Mazdak'";

I used this code :
string str="CompanyName LIKE '%"+DropDownList1.SelectedItem.Text+"'";
ds.Tables["Customers"].DefaultView.RowFilter=str;
DataGrid1.DataSource=ds;
DataGrid1.DataBind();
I have a drop down list box,it's item form A to Z,when user choose one,data grid must filter by the words that their first character are like that.when I use this code nothing
happen,did I miss something?

According to the code above you are matching results where the last letter is the one selected :-P
string str="CompanyName LIKE '"+DropDownList1.SelectedItem.Text+"%'"; is the correct version
Hopefully that is what is causing the problem, because according to the docs what you have should work.

No ,that was not the problem. 
It seems that datagrid does not update.

I agree with James on this:
string str="CompanyName LIKE '"+DropDownList1.SelectedItem.Text+"%'"; is the correct version
where do you have that code, in what event ?.
I assume you know if DropDownList changes the filter will not do it automatically.
sorry if this is too obvious.

I need a SQL statement which retreive all strings start with special charachter.
For example all words start with 'M' in recordserts.

I'm trying to page a recordset, but in one case I have a problem. The code looks like:
<br />
sSQL = "SELECT Table1.*, Table2.* " &_<br />
"FROM Table1 LEFT JOIN Table2 ON Table1.Name = Table2.Name"<br />
rec.CursorLocation = adUseClient<br />
rec.CacheSize = 25<br />
rec.PageSize = 25<br />
rec.Open sSQL, con, adOpenForwardOnly, adLockReadOnly<br />
In case that the Table1.Name exists in Table2.Name, all is working correct. But if not... I'm getting E_FAIL from Microsoft Cursor Engine when I'm trying to do anything with returned Recordset. Though without paging and having a client cursor, it works fine.
Any ideas what is going on and how to fix it?

What is sinfully wrong with the below implementation?
I am just doing some simple learning experiments and the below code is 2000 times slower then using MySQL's api. If that kind of difference was typical no one would be using ADO. So I assume it is missing something standard.
CADODatabase MyADO;
CString ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};\
SERVER=localhost;\
PORT=986;\
DATABASE=genealogy;\
USER=user;\
PASSWORD=pass;\
OPTION=4;";
if(MyADO.Open(ConnectionString))
{
Person *MyPer;
long int pnum = Persons.GetSize();
long int newid;
long int i;
CString sql;
for (i=1;i<pnum;i++)
{
MyPer = (Person*)Persons[i];
if(MyPer!=NULL)
{
sql.Format("INSERT INTO ind VALUES (%d,'%s','%s','%s',%s,%s,%d);",
MyPer->id,MyPer->first,MyPer->last,MyPer->sex,NULL,NULL,0);
MyADO.Execute(sql);
}
}
MyADO.Close();
}

Just wondering if anyone can help me. I've written quite a few queries now, but I was wondering if I could do this with a single query;
I have four tables in Access;
tblJobs ( ID, ... )
tblAreas ( ID, ... )
tblSchedule ( ID, JobID, AreaID, ... )
tblJobAreaLink ( JobID, AreaID ) I have a function in the program to delete a job record, and I want to be able to automatically delete all related records in the tables above.
So far I have:
con.Execute "DELETE * FROM tblJobs WHERE ID=" & id
con.Execute "DELETE * FROM tblSchedule WHERE JobID=" & id But I want to be able to delete the areas too - how can I go about this in one statement?
Thanks!

Use the "Relationships" tool to define JobID and AreaID as foreign keys, and set "Cascade Delete Related Records" on the relationships.
