well, shame on me. I found the problem...
I was reading the data to the pointer, that i didn't reserved in the memory. So i erased the memory where "i" was stored.

Did you check you ColumnsNumber. I think it would be 1.

I can't see anything in your code that would cause that problem. Are you sure the value of ColumnsNumber is what you expect?

Also, check to make sure your sizes in the dbffile.read() calls are correct - you might be encountering a memory smashing bug.

You do one thing, replace the variable 'i' with something else. Because that might be clashing.

Hi All,

How does one use cout to display hex characters?

For example a variable is set to 0x60, but when you call cout << var << endl; you get ' because that is 0x60 on the ASCII table.

Rich

The old fashion (C) way:

int i = 0x60;

printf("%02X", i); // prints "60"
printf("%04X", i); // prints "0060"

Hi !
I put some sample code for your. You can make use of it, as per your need.

int n=20;
cout << "decimal: " << n << endl;

//--- Print hex with leading zeros
cout << "hex : ";
for (int i=2*sizeof(int) - 1; i>=0; i--)
{
cout << "0123456789ABCDEF"[((n >> i*4) & 0xF)];
cout << endl << endl;
}

Why not use:

cout << std::hex << var << endl;

I have to agree with David, why not stick to the iostream idioms to do the trick. Although if 'var' is defined as type 'char' then you'll need to be a little sneaky since the formatting specifier hex modifies the output base of int's but does not modify the formatting of char's.

<br />
<br />
#include <iostream.h><br />
#include <iomanip.h><br />
<br />
<br />
char var = 0x60;<br />
<br />
cout << hex << var << endl;    // output: `<br />
<br />
cout << hex << (int) var << endl;  // output: 60<br />
<br />
// want to guarantee a minimum width of 2 and padded with '0'?<br />
<br />
cout << hex << setw(2) << setfill('0') << (int) var << endl;<br />
<br />

I want make SQL operation(Add, Modify, Delete records) to Access using ODBC.
I found many method to done(ADO, CRecordSet ), but which one is good for using ?

Thanks Smile | :)

One of the simplest methods is to create a DSN for your Access database. Then use ClassWizard to create a CRecordset-derived object. It will ask you which DSN to use. You can then select the tables and columns to use. See here for an example.

Can i directly using ODBC connection strings and write the database location (like C:\testing\testingdb.mdb) in the ODBC connection strings ?
Because DSN need setting it before using.

Thanks your reply.

Sure. That same article shows how to use a DSN-less connection.

Hi,

In my application i have two views say View1 and View2. When the data in the document changes each view is notified synchronously. But if i hover mouse over the view2 when the the data in document is changing and the notification is not yet sent a event is fired by mouse hover even though i have used CWaitCursor in document. I need to prevent this as its trying to access the old data when new data is loading.

Any help please..

Thanks in advance..
