then you have to dynamically load function or take long route.. i never tried, but have a try make a new dll based project with same dll name .. this will generate you new lib file.. which i believe can be used with existing dll... my assumption is that dll lib file contain runtime declaration of function signature

You need to have some exported symbol/function to generate .lib.

I can use FindWindow("#32770", "MFCProgramName") to find a MFC program's dialog, and then I can PostMessage() to the dialog.

How can I send message to a Win32 Console Application?
Thanks!

In general a console application has no message pump and so can't process messages. If you're coding a console application there's nothing stopping you from adding a message pump however.

Hi
You can try creating a CFrameWnd derived class . Overwrite OnCreate of this windows make it hidden . And you can use the message map for framewnd easily to receive messages into the app

What I do is disable them and move them to a position that is off the property sheet.

No you don't actually put in the buttons yourself... It's created for you by default (not by dialog designer) - I was expecting you'd need to specify you don't want APPLY/HELP button from dwStyle or dwExStyle:

virtual BOOL Create(CWnd* pParentWnd = NULL, DWORD dwStyle = WS_POPUP | WS_CAPTION | DS_MODALFRAME | WS_VISIBLE, DWORD dwExStyle = WS_EX_DLGMODALFRAME);

Any idea? Thanks.

Yeah, that is correct. So what you do, in your sheet's OnInitDialog function is:

CWnd *pWnd = GetDlgItem(ID_HELP);
pWnd->EnableWindow(FALSE);
pWnd->MoveWindow(-100, -100, 0, 0, FALSE);
pWnd->ModifyStyle(WS_TABSTOP, 0);

And do the same for the Apply button.

Sorry, that's what I get for doing it off the top of my head. The ID of the help button is IDHELP, not ID_HELP. The ID of the Apply button is ID_APPLY_NOW.

Thanks, it works. How do you set alignment to bottom right of dialog/property sheet though?

I found CBRS_ALIGN_BOTTOM and other stuff from AFXRES.h but not sure which API to call. Thanks a bunch.

In the propertysheet constructor you put the following

m_psh.dwFlags |= PSH_NOAPPLYNOW;
m_psh.dwFlags &= ~(PSH_HASHELP);

and in each of the propertypage constructors put

m_psp.dwFlags &= ~PSP_HASHELP;

Then the help and apply buttons will be removed.

declaring item in combo box...

i was wondering, in a combo box, in order to add item we can just go to properties and add them one by one n separate them by pressing ctrl+Enter. But, do I still need to declare those items in the codes(eg. using AddString)? I'm using VC6 and using a dialog based application.

Thanks in advance.

no, you already added them to control!

Transparency of controls

Hi everybody,

can anybody please direct me to a web site or an article (I could not find anything helpful) about how to make controls to be transparent. I use Visual Studio 2005 to make a Visual C++ dialog based application, and I use ATL only. Even though I specify a static control should be transparent, it is not. The background is static, it does not change, but neither static controls nor the captions of group box controls are rendered transparently.
Thanks for your help.

Re: Transparency of controls

Okay, I found it:

I need to handle the message OnCtlColorStatic:
::SetBkMode((HDC)wParam, TRANSPARENT);
return (LRESULT) GetStockObject (HOLLOW_BRUSH);

and my static controls are all transparent.

But I can still not make group box captions to be trtansparent.

Thanks.

Same problem with a groupbox. You can make it owner drawn and draw it yourself (it's a button).
If only WM_EX_TRANSPARENT style was implemented for all controls...

How can a user-mode client achieve direct access to kernel streaming(KS) filter in video capture? I know there is a sample from microsoft using KS in audio rendering and capture. Is KS feasible in video capture? Any suggesion and samples will be appreciated.
