Thanks, that's a great link. It does have the unfortunate side effect of making me want to jab a fork in my eye. What a frigging mess Frown | :(

Pretty normal while working with COM if you ask me.

hi
I made this
http://www.4shared.com/file/105379147/23d04050/dualactionmfcbutton.html[^]

it did not work as dual function button

But it work well as dual hover and dual tooltips

Can anyone help me in making it dual function button?!
THanks

Probably, but you'll need to post your code snippets here (i.e., only relevant code), rather than require someone to download your whole project from some other site. Some of us have soap operas to watch and Bonbons to eat so time is important.

Here is the code snippet i wrote when the custom button clicked

void CHashiDlg::On_AddSubtract_action()
{

UpdateData( );
double numA ,numB ,result ;
numA = atof(m_num1) ;// edit control number1
numB = atof(m_num2) ;// edit control number2

if(m_two_actions_botn.OnRight()) { // check whether the mouse clicked right half

m_results = numA + numB ;

UpdateData(FALSE );

}
else {
m_results = numA - numB ;

UpdateData(FALSE );

}

UpdateData(FALSE );
}
it performs no action loll

The first thing I'd do is get rid of those unnecessary UpdateData() calls. They are a never-ending source of problems simply because most folks do not know how to use them.

You should then have something akin to:

void CHashiDlg::On_AddSubtract_action() 
{
    CString strNumA;
            strNumB,
            strResult;
 
    m_num1.GetWindowText(strNumA);
    m_num2.GetWindowText(strNumB);
 
    double numA = atof(strNumA),
           numB = atof(strNumB);
 
    // check whether the mouse clicked right half
    if (m_two_actions_botn.OnRight())
        strResult.Format("%f", numA + numB);
    else
        strResult.Format("%f", numA - numB);
        
    m_results.SetWindowText(strResult);
}

Ohh still not working !!

That tells us a lot. Roll eyes | :rolleyes:

what is the problem?

How could I, or anyone else, possibly know? What have you tried so far? What code do you currently have in place? Does it compile? Are you getting runtime errors (e.g., assertions, exceptions)? Have you used the debugger (and stepped through each line of code in question)?

no errors

but it performs nothing

loll

Is On_AddSubtract_action() being called?

Hi
Can you look at the codes i made?
in the project?

I am reading a huge .txt file which has data arranged in form of rows and columns.
There are 60 columns and 10000 rows and i have to read each data(which is integer or float type) from the file to use it for some purpose.

I am using scanf() to read. But this is taking long time and the program slows down.

how can i improve the speed of reading ??????????

Regards

raghav

You can use Memory Mapped Files[^]

You can get more speed if you're ready to use up more memory.
Read the entire file into a CString variable.
And then use CString::Tokenize to read each field.

The CString variable will use up enough memory to load the entire file.
Or you can logically divide the file into fixed size chunks and read one chunk at a time and do the same processing.

I love work. It gives me something to do between weekends.

Split each line into fields and use atof[^] (to read floats) and atol[^] (to read integers). That should be quicker than scanf.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

By not reading one line at a time from disk.
