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?

Hi,
I am developing a console type application that accepts command from the user and executes it, if it is valid.
This is a Dialog based application. I have only a CEdit control in this dialog box.
When this application starts, the focus is in the CEdit control and the entire initial text is selected.
How do i keep the focus without selecting the whole initial text. I tried to set selection in InitDialog. But things didnt work as I expected.
Please suggest me a solution for this
Thanks
Saravanan

Hi
Do you test WM_SETFOCUS
|
|
|
|
|
Hi,
After
1)seting focus to the edit control in the initdialog
2) send EM_SETSEL Message to that edit control with the info of setting the text.
3) return false in the initdialog.
Regards,
FarPointer

I have dialog (window/form) that inherits from the CDialog class. This dialog has various controls on it including a few buttons and textboxes.
I am trying to get some keyboard events (key presses) to fire some events but its not working.
In the Header file for the dialog i have this as a protected declaration
[code]
afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
[/code]
I have an ON_WM_KEYDOWN() event created and its corresponding method in the .cpp file
[code]
void COpenGLMFCDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
[/code]
Within this method i have written some test code to change the text in a textbox just to see whether the event is fired correctly, but the text is never changed. I also tried changing the dialog's name and also firing some Message Boxes ... but nothing worked.
The code in the "OnKeyDown" method is as follows:
[code]
void COpenGLMFCDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags){
switch(nChar)
{
case VK_RETURN:
SetWindowText("You pressed Enter");
break;
case VK_F1:
SetWindowText("Help is not available at the moment");
break;
case VK_DELETE:
//SetWindowText("Can't Delete This");
//AfxMessageBox("Testing");
m_Txt_Test.SetWindowText("The Event was fired");
break;
case VK_DIVIDE:
//SetWindowText("Testing");
m_Txt_Test.SetWindowText("Another Event fired");
break;
default:
SetWindowText("Whatever");
}
}
[/code]
Could someone please (pretty please) tell me why this isn't working and whether i have done all that is needed for a keyboard event to fired & a result to be seen on screen.
Thanks in advance.

Hello braveheartkenya ,
If you have each control's in the form then WM_KEYDOWN and UP isn't work and All Event's(WM_KEYDOWN and Up) send
to controls unless in the form non controls
