It seems that it open a access database and create a table with 5 cols and then read all records of MyTable and insert datas to these cols
|
|
|
|
|
i also think so..then why it is not creating database table with 5 col....and inserting data in that...do you have any idea.....
|
|
|
|
|
And when you create your database why use open and also MoveNext you dont have any records except one

Try removing the .mdb from your create table statement.

Not sure exactly what your're trying to do, but your insert into statements don't look right.
To add records, you can either use insert into statements or recordset's addnew/update, but you don't need to do both.
database.Execute( "INSERT INTO MyTable(MarketNo, MarketName, Bid, Ask, MarketState) VALUES('1', 'myname', '123', '150', 'A')" );

ok...but i am not able to c mytable..it is not creating the table..why..

You might have more luck in the Database Forum http://www.codeproject.com/script/comments/forums.asp?forumid=1725[^], but I don't think Access understands the same column types as SQL (i.e. you might need to change the varchar() to Text or something).
Do you have Access installed? Try creating your database in Access, and then maybe you can figure out the correct create table statement.

Why not wrap this code in a TRY/CATCH block to see why it is failing?

I seem to remember that you need to register the .mdb (forgot how to do it exactly), but I don't think you are going to have any luck until you register the database with Access. Or have things changed since my last foray into DBs about 5 years ago?

where can i get sample programs for serial communication using MFC?
|
|
|
|
|
|
|
Sometimes, while allocating memory in my programs, I get NULL in responce to call of new operator.
Sometimes, when I execute following pair of statements, I get Heap Error.
TCHAR * szText = new TCHAR[iLen * 7] ;
//... Some Code
delete [] szText ; // Causes heap error
Where and what I might be doing wrong?

What is the value of iLen ? And what is the code missing between these two lines. You don't provide any valuable information for us to help you...
|
|
|
|
|
You are right, not enough information:
Value of iLen is > 0 < 200. Moreover, between the lines, we are just calling string manipulation functions like strlen, strcpy etc. But when the delete []szText is executed, heap corruption message follows....

Can you post the exact code ? We cannot help if you don't provide meaningfull informations.

What if these are omitted? Does the problem still exist? If not, it could be that you are writing outside of the allocated memory.

Is this the problem?
Also try to use Safe String APIs instead of strcpy etc

This is the code snippet that you need to focus on. What is the value of ilen? What does szBuffer look like each iteration of the loop? How are you verifying that szHexDump is big enough for iLen concatenations?
