Question about CEdit

Hi.
I set my dialog color to black with GetStockObject( BLACK_BRUSH );, then I put edit control with different 'BkColor'

CDC *pEditDC=m_edtInfo.GetDC();<br />
pEditDC->SetBkColor(RGB(230,251,251));<br />
pEditDC->SetTextColor(RGB(255,255,255));<br />
ReleaseDC(pEditDC);

When my dialog shows at first (before my edit control has no input string) I don't even see it (all dialog is black)! When I populate edit control m_edtInfo.SetWindowText('some text') text is displayed and edit ctrl's BkColor is shown but only behind the text not on all edit ctrl rectangle.why?
How to get all edit ctrl's region being filled with BkColour, even at first?
Thanks!
P.S.
My apology for my language.

Trying to set the back colour like this will not work. You need to override WM_CTLCOLOR in the dialog class to change the colours of the dialog itself and its controls.

Thanks for replay.
I'm already overriding that:

HBRUSH CDialList::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
	<br />
	if( nCtlColor == CTLCOLOR_DLG )<br />
	{<br />
		m_myHbr = (HBRUSH) GetStockObject( BLACK_BRUSH ); <br />
	}<br />
	return m_myHbr;<br />
}<br />

for setting my dialog color to black!
You are saying I can put more code on it and deal with color for my edit ctrl.
Ok I put additional line code (if statement):

if( nCtlColor == CTLCOLOR_EDIT )<br />

but can you tell me what to use to set color to RGB value and not to use GetStockObject?
Thanks!

This is how it looks now:

<br />
HBRUSH CDialList::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
	<br />
	if( nCtlColor == CTLCOLOR_DLG )//for dialog<br />
	{<br />
		m_myHbr = (HBRUSH) GetStockObject( BLACK_BRUSH ); <br />
	}<br />
	if( nCtlColor == CTLCOLOR_EDIT )//for edit ctrl<br />
	{<br />
		CDC *pEditDC=m_edtInfo.GetDC();<br />
                //set text to black<br />
		SetTextColor(*pEditDC,RGB(255,255,255));<br />
                //set background to RGB(230,251,251)<br />
		m_myHbr = (HBRUSH) pEditDC->SetBkColor(RGB(230,251,251));<br />
		ReleaseDC(pEditDC);<br />
	}<br />
	return m_myHbr;<br />
}<br />

But unfortunate still doesn't work!?!

You shouldn't be getting a DC for the control.

Everything you need is passed to your OnCtlColor() method.
You should use the passed DC.

Easiest would be if you look into one of the controls shown in the Editcontrol-section of codeproject[^].

You will find a lot of source code to look how it is done.
Chris Losinger has made a coloring Editcontrol I use.

You can get the whole rectangle with void CEdit::GetRect( LPRECT lpRect ) const; and insteads of set the background of the CEdit, do it with the lpRect.

Then use the CDialog::OnInitDialog (); to make your changes and...

remember to change the background of the dialog before changing/filling the edits

all depends which string class you're using. basic C-style strings (char*), CString, std::string, BSTR ...??

How to disable the sounds of message box ?

Nelek19-Sep-07 22:27

Nelek

19-Sep-07 22:27

I would like to know if there is any way to quit programatically the usual "cling" when a MessageBox or an AfxMessageBox is shown.

I have taken a look to the classes in the help but I found nothing and I don't want to go to the computer sound settings, I want to do it just in my app.

Can someone give me some info?

Re: How to disable the sounds of message box ?

Take a look in the registry...

HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default

These are the default sounds.

Notice that other apps can substitute their own set of sounds for
system events by adding subkeys under

HKEY_CURRENT_USER\AppEvents\Schemes\Apps

Note I haven't messed with this but maybe it will help point you toward a solution Smile | :)

But oign into the registry, will be the same as doing it through the explorer... And I would like not to deactivate the sounds for the operating system. Just when im executing my app. Because when Im testing things (the error messages that the user will have when something goes wrong) the sounds nerve me. I check ALL the errors that the user can have. So... that's the reason for just a piece of code inside my app.

Anyways, thanks.

I can disable them by starting app, and enable them another time by going out the app.

Not really - you can programmatically alter the registry.

Regardless, I tried messing with this, and while my registry entries cause the sound settings
for my app to appear nicely in the "Sounds" control panel applet, the system (XP SP2) does
NOT use my settings when running the application Frown | :(

Please let me know if you find a solution - I will do the same Smile | :)

Finding files

19-Sep-07 21:42

Is there any way to determine the number of files and directories on a given volume without having to resort to the find file api's?

I'm using the FindFirst FindNext api's to iterate every file on the volume, for each file I then perform a few tasks. The whole process could take anywhere between 10 seconds and 10 minutes to complete. So I need to display the progress to the user. The trouble is I have nothing to base this progress on. If I had the total number of files before hand, I could compare this to the current and display it on a progress bar.

I'm open to suggestions here.

I have never faced with this functions, but...

is it possible to emulate the call of "properties" when a right click is made on a folder and isolate the parameter number of files / number of subfolders???

If windows can make it... we can make it, can't we?

Bring up the properties dialog for C:\Windows, you will see the count of files and folders steadily increasing which leads me to believe that internaly it is also using the FindFiles set of api's.

I suppose if I run a bare bones loop which only increases a counter, it should only take a second or two.

What do you mean with "bare bones loop"?

Just doing FindFirst and FindNext to determine the end of the list and doing nothing more but increase a counter? or is it something special? It's the first time I "listen" about.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
