I have no idea what might be the problem so this is just a WAG, are you building your projects using the Platform SDK for Vista and you have set WINVER appropriately?

Hi,
I'm having some trouble using classes defined in one project (compiled as exe) in another project (also to be compiled as exe, to run in a separate process, but part of the same solution). Is it possible at all? Or do I have to import all the .cpp files into the other project and compile them there?

I've set up a project dependency, but that doesn't work. I get unresolved externals during compilation.
Note, I've also set up project references.

All the code an individual project needs to build must be
part of the project, or available to the project through a
library.

How you manage the physical files is up to you.

I personally use a "common" folder in the solution's folder to
keep my common/shared cpp/.h files in one location - only one codebase
to update. All projects can reference files there using relative paths,
something like "..\common\somecommoncode.h".

How to fix a window at the top?

Hi,

When I create the dialog box (second dialog) in the first dialog box it stays always above the first one. I can push to a button in the first dialog box while the second one stays above it.But when I create them at the begining of the program in the main dialog box (main dialog box is different than the first dialog box) then if I touch to the first dialog box the second one goes below the first one.How can I fix the second dialog box above the first dialog box when I create them at the beginning of the program?

Thanks
ibrahim

As mike said, u can use SetWindowPos( m_hWnd, HWND_TOPMOST, Left, Top, Width, Height, SWP_SHOWWINDOW );

That didn't solve my problem.I think it will be better if I write the code sample.

Creating the dialogs as global.

pKeyboard = new CKeyboard;
pKeyboard->Create(IDD_KEYBOARD,this);
::SetWindowPos(pKeyboard->m_hWnd, HWND_TOPMOST,0,0,cxScreen,2*cyScreen/5, SWP_SHOWWINDOW ); 

pPhoneEditor = new CPhoneEditor;
pPhoneEditor->Create(IDD_PHONEEDITOR,this);
pPhoneEditor->SetWindowPos(&wndTop,0,0,cxScreen,cyScreen,SWP_HIDEWINDOW);

Is there a problem in this code?

If you use DoModal () to display the second dialog box, it will be fixed at the top until you close it. This is called a "modal" dialog box.

But I want that I can push a button or write something to an editbox in the first dialog box while the second dialog is on the top.When I create the dialog box as modal I think that I cannot use the first dialog box?

Tracking mouse event on a Bitmapbutton [modified]

That's correct. In that case, you should probably use led mike's suggestion instead of DoModal ().

Dear All,

Please guide me how to use TrackMouseEvent() to track the events of mouse on a CBitmapbutton. Please advice.
Also I see a message map

ON_BN_HILITE( <id>, <memberFxn> ) afx_msg void memberFxn( );

Is it possible to use when a button is highlighted.

Regards,
Banu

I see, so please tell me what is the wrong with the below code
//DoDataExchange

DDX_Control(pDX, IDC_BUTTON9, m_button9);

//Message map

ON_BN_HILITE(IDC_BUTTON9,&Test::OnHighlight)

//Function declaration and button declaration

afx_msg void OnHighlight();
CBitmapButton m_button9;

//Function definition

void Test::OnHighlight() 
{
	MessageBox(L"Button Highlighted");

}

Also the notify property of the button is true and Owner draw is set to false. I have tried all the above and then only I am asking questions in this forum, if you have time please help otherwise please don't disgrace the new members and novice programmers.

Hi,

is there the possibility to get a MouseOver Event for Combobox Items?

I want a bubble to pop up, when the users mousepointer is over a combobox item, so i would need the event, and the value of the item the mouse is over.

Can someone help me?

Thank you,

Johannes

Have you called EnableToolTips(TRUE)? Do you have a handler for TTN_NEEDTEXTA and TTN_NEEDTEXTW?

Thanks for you answer.

I decided to use a control from codeguru.com (http://www.codeguru.com/cpp/controls/combobox/tooltips/article.php/c4949/).

It works fine so far, but I have another Problem:

I want to have a multiline ToolTip Text ("line1 \n line2"). I read that I have to call SetMaxTipWidth() from the CToolTipCtrl class.
The Code of the codeguru control manipulates the ToolTip text in the function CTooltipListCtrl::OnToolTipText(...).

TOOLTIPTEXTA* pTTTA = (TOOLTIPTEXTA*)pNMHDR;
TOOLTIPTEXTW* pTTTW = (TOOLTIPTEXTW*)pNMHDR;

if (pNMHDR->code == TTN_NEEDTEXTA)
lstrcpyn(pTTTA->szText, sTipText, 80);
else
_mbstowcsz(pTTTW->szText, sTipText, 80);

Can someone tell me how to get the CToolTipCtrl pointer in the CTooltipListCtrl class(derived FROM CListCtrl), to call it's SetMaxTipWidth() function to get a Multiline ToolTipText?

Thanks for your help...

I am trying to create a progress dialog box in the below event. But Progress dialog box is not displayed, it is working fine when I comment th loop, I the lenthy operation is very much similar to the loop.
I want the progressbar to be initiated with thread,
Please advice.

Have you set a breakpoint in CPrgDlg::OnInitDialog() to verify that control is reaching that method?

You should be using

CWinThread* AfxBeginThread(
   CRuntimeClass* pThreadClass,
   int nPriority = THREAD_PRIORITY_NORMAL,
   UINT nStackSize = 0,
   DWORD dwCreateFlags = 0,
   LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL 
);

instead of

pThread->CreateThread();

to create a UI thread. Otherwise, your thread won't get the
WM_MYTHREADMESSAGE you post to it.

*Edit*<br />
Actually you can leave your thread creation code the way it is as<br />
long as your ThreadPrgIndiaction class has an InitInstance() override<br />
that returns TRUE.  That will cause the message queue to be created for <br />
the thread.<br />

But the above code is working fine, with out the while loop. The problem, progress bar indication is shown on the dialog, when while loop is placed.
