Button functions

[Darren2308]

void CU6b82Dlg::OnDemo()

{
UpdateData (TRUE);


{

m_Sequence="BBB";

m_Sequence2="AAA";

m_Sequence3="CDEF";

m_Sequence4="abcde";



}
UpdateData (FALSE);
}


this is how it appears if the button had a single function...

however I need to make it so when demo is pressed again this firstly clears then a new set of letter appears in the sequences

Ah, so you want to move data from one edit to another. Then, it should be like this:

void CU6b82Dlg::OnDemo()
{
   // take data from controls into variables
   UpdateData (TRUE);

   CString sequence;

   // this is just an example
   switch(rand() % 5)
   {
    case 1: sequence="AAA"; break;
    case 2: sequence="BBB"; break;
    case 3: sequence="CCC"; break;
    case 4: sequence="DDD"; break;
   }

   // swap data
   m_Sequence5 = m_Sequence4;
   m_Sequence4 = m_Sequence3;
   m_Sequence3 = m_Sequence2;
   m_Sequence2 = m_Sequence1;
   m_Sequence5 = sequence;

   // put data in controls from variables
   UpdateData (FALSE);
}

}

I think you have got me confused i simply want a way to get my button to but in information of my choice. It can be anything. But for example the first click will put letters into all four edit boxes

eg

m_Sequence "AAAA"
m_Sequence2"BBBB"
m_Sequence3"CCCC"
m_Sequence4"DDDD"

then if i press demo again it will replace these with for example

m_Sequence "ADAD"
m_Sequence2"ADCA"
m_Sequence3"AGEB"
m_Sequence4"CGEBA"

I simply need to know how when a button is pressed more than once/numerous times, how I set up this function

I think we already gave you enough information to make this work. Here is something more. You should be able to use it:

void CU6b82Dlg::OnDemo()
{
   switch(m_State)
   {
    case 0:
        // do something
        break;
    case 1:
        // do something
        break;
    case 2:
        // do something
        break;
    case 3:
        // do something
        break;
    case 4:
        // do something
        break;
   }

    m_State++;
    m_State %= 5;
}
