Thread: Combo Box in MFC, how to randomize data of it...please help!

I have a combo box (MFC) that have 3 data entries in it.

Lets say they are...

data1
data2
data3

How do I make it so that when i press a button, the data randomize and display? Please help.

First make sure the Sort property of the ComboBox is turned off.

And the rest.... there must be a simpler way to do this but I'll give it a try:

Code:

int nofItems = 0;
int len = 0;  // item length
int randIndex = 0; // index to item (random)
char item[1024];

nofItems = Box.GetCount();

srand(time(NULL));

for(int i = 0; i < nofItems; i++) 
{	
  randIndex = rand() % nofItems;  // pick random item
  len = Box.GetLBTextLen(randIndex);  // get length of string
  Box.GetLBText(randIndex, item);  // save string 
  Box.DeleteString(randIndex);  // delete string from list	
  Box.AddString(item);  // add string at end of list
}

Thank you for replying, but I'm still unclear about this. I assumed that "Box" is my combobox, but my combobox control name is IDC_COMBOTEST, how do I tell the name of my box?

In VC++ 6.0:

Open ClassWizzard: View -> ClassWizzard (or CTRL+W)
Select tab "Member Variables"
Select your control ID (IDC_COMBOTEST)
Press button "Add variable..."
Enter the name of the member variable (m_DialogBox)
Category: Control (not String)
Variable type: CComboBox
Press "OK"

Now you have added a new variable called m_DialoxBox.
You can use this variable to update the Dialog Box.
