Combo Box and Edit Box

[Eversman]

Hey, I am using Visual C++, and I created a Combo Box and added the options into it. Now, when someone selects one of the options, I want a text describing the option to appear in an edit box. I have looked around and only found a few things, but nothing really helped. Thanks for the help

The combox by default displays the text in the list control in the edit box as each item is selected. I'm not sure, but you could maybe try capturing ON_CBN_EDITUPDATE or ON_CBN_SELCHANGE and then forcing the edit to change it's value. This approach won't work if the drop down list and edit field are dual synchronized. What I mean by this is if you set the edit content it make force a new item to be selected inside the list box as well and visa-versa. If this is the case you will have to subclass the CComboBox control and override this functionality. Cheers :) How do I print my voice mail?

I tried doing that, didn't work, here is my code. void CDEPDlg::OnSelchangeCombo1() { // TODO: Add your control notification handler code here UpdateData(true); if(m_type1=="Run #1") { m_purp1="Test"; } UpdateData(false); } m_type1 is the combo box, and Run #1 is the option in the combo box. m_purp1 is the edit box that i want it to display the description. I know it is wrong, so criticize all you want, just need help with it. Thanks

It's been a while since I subclassed comboboxes or dealt with them for that matter :) How did you get m_purp1and m_type1 to map to the 2 controls that make up an CComboBox? How do I print my voice mail?

I went to the class wizard and did it there. m_type1 is a CString and m_purp1 is a CString also

If you're wanting to update an Edit Box that isn't the one at the top of the Combo Box (which is what it looks like) try this

void CDEPDlg::OnSelchangeCombo1()
{
CString text;
m_type1.GetWindowText (&text);
if(text == "Run #1")
m_purp1.SetWindowText("Test");

}

Thanks for the help. I am getting this error, C:\DEP\DEPDlg.cpp(182) : error C2664: 'void __thiscall CWnd::GetWindowTextA(class CString &) const' : cannot convert parameter 1 from 'class CString *' to 'class CString &' A reference that is not to 'const' cannot be bound to a non-lvalue

I took out the & in the (&text) and it worked, and it works, but i have to select the Run #1 twice for the Test to show up in the edit box. Thanks

but i have to select the Run #1 twice for the Test to show up in the edit box Try chaging your message from CBN_SELCHANGE to CBN_SELENDOK. I think the reason you're having to select it twice is that CBN_SELCHANGE is sent before the selection changes, therefore the text, "Run #1" in your case, isn't actually in the edit portion when the message is processed. CBN_SELENDOK is sent after the selection is made. Just use class wizard to remove the selchange and add a selend - Aaron - Aaron

Thanks for your help. I tried that and I still have to do it twice to get it to show up. Any more ideas?

[monrobot13]

Figured that would work, guess not though. Try this

int cur = m_type1.GetCurSel ();
CString text;
m_type1.GetLBText (cur, text);
if (text == "Run #1")
m_purp1.SetWindowText ("Test");
