If I add a control disabled - how do I enable it later?
Is there a setcontrol class?

[Parker]

As far as I know, EnableWindow

Code Select Expand

declare import, EnableWindow(unsigned int hWnd, int bEnable),int;

...
EnableWindow(pControl->m_hWnd, 1); // To enable the control

is the only way.

Need to give me more detail on how to do this.
This is the initial declarition line:
   d1.AddControl(CTLISTVIEW,"",10,10,500,145,
      AWS_DISABLED|ALVS_REPORT|AWS_BORDER|AWS_HSCROLL|AWS_VSCROLL,AWS_EX_CLIENTEDGE,LISTVIEW_1);
What would turn it on?

[Parker]

You can use the GetDlgItem function to get an HWND to pass to EnableWindow, it would look like this

Code Select Expand

EnableWindow(GetDlgItem(d1.m_hWnd, LISTVIEW_1), 1);
sorry I'm a little busy, you'll have to convert the declare from msdn

Controls are enabled by default.

[Parker]

But not if they're disabled. See above, AWS_DISABLED is explicitly passed.

For GetDlgItem, insert this into your code

Code Select Expand

import unsigned int GetDlgItem(unsigned int hDlg, int nIDDlgItem);

[Bruce Peaslee]

Ouch. Got me.

I better get some sleep (no cracks please, Paul) - I'll look again tomorrow.

[Rock Ridge Farm (Larry)]

Yes it is disabled at start - I want to be able to turn it off/on on demand.

Just use GetControl to get a pointer to the control.  If you in a method of the dialog:

pControl = GetControl(id);
EnableWindow(pControl->m_hWnd, true);

Or if your not in a method of the dialog

pControl = dlg.GetControl(id);
EnableWindow(pControl->m_hWnd, true);

The is no reason to use GetDlgItem

I looked in the includes - is EnableWindow a function?
I can not find it.

[Bruce Peaslee]

I found this in keno.src

DECLARE IMPORT,EnableWindow(hwnd as int,bEnable as int),int;

[Rock Ridge Farm (Larry)]

That solves the compile error - now the program just crashes.

[Rock Ridge Farm (Larry)]

Got past the crash but still does not make the listview visable.

[Parker]

I had the same problem when I was testing this, it looks like the listview doesn't revert back to the correct color, but is still enabled. If there is a function to set the color of a listview control, try putting that right after the EnableWindow call and see if it works.
