Hi I want to make a loading message box which disappears once the loading was finished.
In order to do that I decided to use the function DialogBox in order to create a modal dialog, however, I couldn't find a message that indicates that dialog has finished drawing itself.
I want to start the loading sequence right after the dialog and the message of "loading" appears on the dialog.

Any suggestions ?

I would like to use a dialog in order to easily make a nice loading message.

Thanks a lot,
Clint

In wich ambient you are doing this? MFC?

In that case you can take OnInitDialog event or.. WM_INITDIALOG

I tried WM_INITDIALOG, but it happens before the dialog has finished drawing itself, so the message doesn't appear.

Try WM_PAINT event

Also WM_PAINT is not good, it happens during the drawing of every control.

Get PROPERTYKEY from Name

Hi all... how i can convert a Property name to a PROPERTYKEY structure (FMTID/PID) by the name?

Example:
From Registry i take: HKEY_CLASSES_ROOT\*\InfoTip

than in my case, the result is: "prop:DocTitle;Type;Size;FileVersion;FileTitle;ProgramDescription"

I have written a function to get sequentially property by property... so i have:
DocTitle
Type
Size
FileVersion
FileTitle
ProgramDescription

I want to translate the correspondent PROPERTYKEY structure (FMTID/PID) or otherwise translate this string to the correspondent replacement as Windows Explorer do.

Any suggestion is appreciated. Thanks in advance!

Hi,
I need to know (source code will be more helpful) how can i filter a list of files which will be displayed in files explorer (like windows explorer) with its extension.
For example when i click on desktop (in tree control in the left) the list of files (ONLY a specified type of files (extension i.e doc...)will be displayed not all files in this directory).

I use :
- CTreeCtrl
- CListCtrl

My application is a SDI MFC .

I'm waiting for response, please help.

You can do it with 7 lines of code in plain C/Win32 api (with undocumented (or not) native controls)

With Visual Studio C++ 2008, how can I put a greek letter in a static

How would you put any letter in a static control?

You may, for instance, use the the escape sequence \xhhhh in the control definition (inside the rc script), e.g.

LTEXT           L"Omega: \x03A9",IDC_STATIC,10,96,300,8

Closing CDialog when it looses the focus

Hi
I have a COptionsDlg class delivered from CDialog. I open it when user right clicks on the main window:

...
COptionsDlg* dlg=new COptionsDlg();
dlg->Create(COptionsDlg::IDD,this);
dlg->ShowWindow(TRUE);
...

Now once it's shown I want to close it when user clicks anywhere outside of COptionsDlg. I tried overriding OnKillFocus() of COptionsDlg but it didn't work.

And also one more question: How can I exchange data between my main window and COptionsDlg?

Any help would be greatly appreciated Smile | :)

When you say you override OnKillFocus and it didn;t work, what did you mean?

It didn't get called? Don't forget ON_WM_KILLFOCUS()...

Did it get called, but the window didn't go? Then you need better code!
Look in Generic Picker Dropdown Control[^] for a window that goes *poof* if you click away from it.

Iain, thank you for your reply.

It gets called.
The problem is it crashes when I use DestroyWindow() inside OnKillFocus().
Looks like you had the same problem(quote from your source code):

void CGenericPickerPopup::OnKillFocus(CWnd* pNewWnd) 
{
	CWnd::OnKillFocus(pNewWnd);
	
    ReleaseCapture();
    //DestroyWindow(); - causes crash when Custom colour dialog appears.
}

// KillFocus problem fix suggested by Paul Wilkerson.
void CGenericPickerPopup::OnActivateApp(BOOL bActive, HTASK hTask) 
{
	CWnd::OnActivateApp(bActive, hTask);
	
	// If Deactivating App, cancel this selection
	if (!bActive)
		EndSelection(CPN_SELENDCANCEL);
}

Now I tried overriding OnActivateApp():

void COptionsDlg::OnActivateApp(BOOL bActive, HTASK hTask) 
{
	CDialog::OnActivateApp(bActive, hTask);
	if (!bActive)DestroyWindow();
}

But nothing seems to be happening. What I'm doing wrong?

Try EndDialog() (you should rarely, if ever, call DestroyWindow().)

Joe Woodbury, thank you for your reply.
EndDialog(IDOK);
That works, but how do I catch the mouseclick outside of the CDialog that I show? I should close it when user clicks outside of the CDialog. Is it possible?

Only if you capture the mouse.

You should call DestroyWindow() to destroy a modeless dialog. In the dialog's PostNcDestroy() method, you should delete the this pointer.

Hehe, you missed the trick.

I do SetCapture, so I get "all" mouse messages. Then I check for OnLButtonUp, and check whether the click was on my popup window or not.

If not on the window, then Destroy the window.

This is the part of the article that owes the most to C Maunder's original colour picker popup. (Only about 10% survives, but this is the biggest bit)
