Hi all,
I have some message boxes that are triggered from some buttons on a dialog. The dialog is set to open in full screen mode. The funny thing is that when the message boxes are triggered they get focus but they go behind my dialog.
Any idea why this is happening and how to get the message box on top of the dialog?
Thanks in advance.

MessageBox(....,HWND hWnd).
if hWnd is hidden, the message box is hidden also.

I'm quite new to MFC programming ... how do i make it visible?

Set your dialog as its parent .
int MessageBox( HWND hWnd (Set it as your dialog handle),
LPCTSTR lpText,
LPCTSTR lpCaption,
UINT uType
);

Sorry i'm unfamiliar with how to create or use a handle. Could you please show me how to?
Thanks in advance

Hi,
Please try this out:-
m_hWnd :- this is the handle of the dialog
MessageBox(m_hWnd,"AM I Working");

If you are using MFC, you can do the following:
CMyDialog::OnButton()
{
::MessageBox(m_hWnd,
"Your message text goes here",
"Caption for your message box",
(MB_OK | MB_ICONINFORMATION));
}In this case, CMyDialog is the name of your dialog class, derived from CDialog (which is in turn derived from CWnd). One of the members of all CWnd-derived objects is m_hWnd, which is the window handle.

I've just tried m_Hwnd as follows:
<br />
::MessageBox(m_hWnd,"This is the LAST record","Last Record",MB_ICONINFORMATION | MB_SYSTEMMODAL);<br />
But its still not coming to the front. Could there be something else wrong?

Kinda off topic...
Don't use MB_SYSTEMMODAL unless you absolutely have to. It prevents the user from doing anything else on the computer other than interact with your message box. It's an exceptionally good way to cause extreme frustration and loss of confidence in your product...

You can try this one...
MessageBox(_T("This is the LAST record"), _T("Last Record"), MB_ICONINFORMATION | MB_SETFOREGROUND);
Since you are using MFC you don't have to use m_hWnd here. MFC does that for you.

It didn't work, but i got another that did.
Replace the MB_SETFOREGROUND with MB_DEFAULT_DESKTOP_ONLY.
I don't know what it means, but it brings it on top and freezes the dialog. Any idea how i can bring it to the front but not freeze the dialog?

I just generate a owner-drawen class from CListBox, and I want to set the item text only in DrawItem function. If CListBox without add one null string previously, DrawItem function is not called.
Thank you for your helps.

DrawItem() is only called when items are to be drawn. If there are no items to draw, it's not called. You still have to add your items as normal.

Send this message from your dialog after doing AddString() to set LB_SETCOUNT...
lResult = SendMessage( // returns LRESULT in lResult (HWND)hWndControl, // handle to destination control
UINT) LB_SETCOUNT, // message ID
(WPARAM) wParam, // = (WPARAM) () wParam;
(LPARAM) lParam // = (LPARAM) () lParam; );
For example,
HRESULT lResult;
lResult = m_MyListBox.SendMessage( (UINT) LB_SETCOUNT,
(WPARAM) m_MyListBox.m_iTotalItemCount,
(LPARAM) 0);
where, m_MyListBox is member object of your Owner Draw ListBox derived class (like CMyListBox derived from CListBox). m_iTotalItemCount as WPARAM is total number of item data to be set. LPARAM can be sent as 0.
One thing needs to be taken into account that the LB_SETCOUNT works only when ListBox Style is "No Data" i.e. LBS_NODATA. Has Strings should be set as FALSE. Setting LB_SETCOUNT will call Draw Item.

I have written a program which reads data from internet and displays it in the web browser control.
And now I'm fuzz about such problems( I have paste the code at the end):
Sometimes the 'DisplayInExplore' works well, but Sometimes it crashs.
1. I have debugged it , and found that 'pHD->write(pSFArray);' method would result in the 'Assert Debug' fatal error. And I can't step into the method write.
2. Sometimes, the 'pHD->write(pSFArray);' could execute successfully, but there was no data to display in the Web Browser control. And when cursor went into the client area of the Web Browser control, the cursor change to the 'wait' status.
So , I have no idea why it works so instable ? Or there are some errors in my function?
Plz give me some suggestion ,Thx.
---------------------------------------------------------------------------
The code is as below:
void CGameInfoDlg::DisplayInExplore(CString strContent)
{
//m_exploreView is the CWebBrowser2
IHTMLDocument2* pHD=(IHTMLDocument2*) m_exploreView.GetDocument();
VARIANT* pVATable=NULL;
SAFEARRAY* pSFArray;
pSFArray = SafeArrayCreateVector(VT_VARIANT, 0, 1);
if(pSFArray!=NULL && pHD!=NULL)
{
SafeArrayAccessData(pSFArray,(LPVOID*) &pVATable);
BSTR bstrContent=strContent.AllocSysString();
pVATable->vt=VT_BSTR;
pVATable->bstrVal=bstrContent;
SafeArrayUnaccessData(pSFArray);
pHD->write(pSFArray);
}
else
{
MessageBox("Errors！");
}
SysFreeString(pVATable->bstrVal);
if(pSFArray!=NULL)
{
SafeArrayDestroy(pSFArray);
}
}

Hi, I'm new to parallel port and would like to ask a few questions:
1. I want to program the parallel port (in C) using VC++, how can I access the port?
2. How can I run my program in windows?
Your help is truly appreciated!

Hi,
Check this port programming[^].
The _inp and _outp are privileged instructions and cannot be used in Win2000 and WinXP. Try using some library. Check this link.
InpOut32.dll[^]
Bye,

I have used InpOut32.dll - really convenient to use, etc.
One thing to watch out for - I was doing InPorts, and got peculiar results until I realised that it returned an 8-bit value, and I wanted a 16-bit value, so I had to do 2 separate InPorts and combine the results.

We do not need to select palette into DC to display rich-colored bitmap for monitor if we set monitor properties as 32 bits or 16 bits.
but, do we need to select palette for Printer DC for printing rich-colored bitmap?
