Hi
I'm very fresh with MFC programming.
My program works on the background, when the user clicks on a predefined hot key, the app performes the action and what I'm trying to do is to notify the user with an ok image on top of the screen for less than a second and disappear.
I tried to create a dialog without window borders with a picture control within, the problems i encountered are:
a. The picture control takes only bmp files which are can not be transparent.
b. Whenever i set the dialog as transparent it is not become on top and start to act weird.
The folowing code works fine except that the picture is not transparent.
1. When the action performed:
<br />
AfxBeginThread(notify,NULL);<br />
2. Opennig the dialog:
<br />
UINT notify(LPVOID pParam){<br />
NotifyDialog saved;<br />
saved.DoModal();<br />
return TRUE;<br />
}<br />
3. The initialization of the dialog:
<br />
BOOL NotifyDialog::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
hDlg = this->m_hWnd;
AfxBeginThread(WaitingToHideIcon,(LPVOID)NULL);<br />
return TRUE;<br />
}<br />
4. Closing the dialog:
<br />
UINT WaitingToHideIcon(LPVOID pParam){<br />
Sleep(600);<br />
EndDialog(hDlg,1);<br />
return 0;<br />
}<br />
5. The resource of the dialog and the picture control:
<br />
IDD_NOTIFYDIALOG DIALOGEX 0, 0, 58, 71<br />
STYLE DS_SETFONT | DS_FIXEDSYS | WS_POPUP | WS_VISIBLE | WS_SYSMENU<br />
EXSTYLE WS_EX_TOPMOST<br />
FONT 8, "MS Shell Dlg", 400, 0, 0x1<br />
BEGIN<br />
CONTROL 143,IDC_STATIC,"Static",SS_BITMAP | SS_CENTERIMAGE,0,0,<br />
58,71<br />
END<br />
<br />
IDB_BITMAP1 BITMAP "res\\OkHandSign.bmp"<br />
I would love to get suggestions and improvements on how to do this
Thanks a lot

When variable i increase to some value(not always definite),exception occurs,is it another bug of ie6.0? Thx a not!
Source code goes as follows:
IHTMLDocument2* pDoc2=NULL;
IHTMLElementCollection* ppCollection=NULL;
IDispatch* ppvdispOption=NULL;
pView->GetDHtmlDocument2(&pDoc2);//pView--a pointer to CHTMLEditView,already asigned with enougth memory
Assert(pDoc2);
pDoc2->get_all(&ppCollection);
Assert(ppCollection);
ppCollection->get_length(&Count);
for (long i=0;i {
_variant_t index ;
index=i;
try
{
ppCollection->item(index,index,&ppvdispOption);
}
catch (...)
{
tagstr.Format("%d",i);
AfxMessageBox(tagstr);
return FALSE;
}
if(!ppvdispOption)
continue;
ppvdispOption->QueryInterface(IID_IHTMLElement,(void **) &pElement);
ppvdispOption->Release();
//.........
}

how can I change alignment of columns of header control? (not text of columns)
I want the fist column be shown in the right of list box.
|
|
|
|

You already created a thread for your question below.
I don't understand your question. Could you rephrase it?
Do you mean the text in the header control's alignment: left-align, center-align, right-align?
this is this.
|
|
|
|
|
when you create the fist column of the header control, it appearers at the topleft of listbox (regardless of the alignment of its text). when you create another column, it appears in right of the first one.
I want the first column be appeared at the topright.

read more carefully about the method
int InsertItem( int nPos, HDITEM* phdi );
it provides all you what

read carefully my question!
I want to apply right to left order to columns, not to text of items.
|

Just use zero for the index when you insert the columns.
<br />
InsertColumn(0, _T("Column far right"));<br />
InsertColumn(0, _T("Column 2nd from right"));<br />
InsertColumn(0, _T("Column 3rd from right"));<br />
If you need it so the entire list control is flush with the right side on the control (say for arabic/hebrew reading) you'd need to set the Right to Left RTL Layout setting in the dialog that contains the control.

Insert a temporary column first, insert the other columns, then delete the temporary column, like:
m_lcFooter.InsertColumn(0, _T("David"));
m_lcFooter.InsertColumn(1, _T("Right Justified"), LVCFMT_RIGHT, 580);
m_lcFooter.InsertColumn(2, _T("Left Justified"), LVCFMT_LEFT, 75);
m_lcFooter.DeleteColumn(0);

How to set the dialog title?
Thank you.
Best regards,
KHLin.

|
|
|

MFC:
SetWindowText("here is the title");
Win32:
SetWindowText(hWnd,"title here");
this is this.

To insert a new item:
CMenu* m;<br />
m = AfxGetApp()->GetMainWnd()->GetMenu();<br />
m = m->GetSubMenu(2);
m->AppendMenu(MF_ENABLED,253,"new item");
When the menu item is clicked, you need a menu-command-range hander in the message-map macro in the .cpp file:
ON_COMMAND_RANGE(200,400,OnMyMenu)//change the first and second parameter to the range you will provide in the second param to AppendMenu()
The implementation will be:
void CMySdiView::OnMyMenu(UINT nItem)<br />
{<br />
}
Now nItem contains the second parameter you gave in AppendMenu(). So you know which one was clicked.
One thing to note is that you must have at least a sub-item in the menu in the resource. Let it be a separator. When no sub-items are present, it gives a headache.
this is this.

first u have to get a handle to the menu or create ur own
HMENU hMenu = CreateMenu();
HMENU hPMenu = CreatePopupMenu();
AppendMenu(hMenu,MF_STRING|MF_POPUP,(UINT_PTR)hPMenu,favmenuTxt);
AppendMenu(hPMenu,MF_STRING,favID,favTxt);
also in ur message process u need to handle for the WM_COMMAND message with (i think) wParam being the command ID

It sounds like you expect this to be simple; in other words, like the IDE is going to provide it for you (Wrong!). You have two choices: (1) write a simple little piece of code that opens a file (for append/write) writes to it, then closes it, for each piece of your code (slow, but worth it), (2) If you are using MFC, then you can use trace statements, they will dump into the debug output window, which you can copy and paste to a text file.

I am a newbie to MFC and want to do the following:
I have a button added to a toolbar. I have also added the following in my code for the function to be executed once the Button is clicked: ON_COMMAND(ID_BUTTONRUN, OnRunTests)What I want is when the button is clicked I want the button state to be disabled and the cursor to look like a Hourglass untill the OnRunTests() is completed.
I tried the :ON_UPDATE_COMMAND_UI(ID_BUTTONRUN, OnToolbarRunUpdate)
but this got executed only after the OnRunTests() completed which is not what I want.
Is there a way for me to change the cursor and the button state as soon as the OnRunTests() is entered and change it back when it is done. Any help and guidance will be appreciated.

In resource.h:
#define WM_DOSOMETHING 12345//or whatever
In mainfrm.h, add a custom-message handler:
afx_msg LRESULT OnDoSomething(WPARAM,LPARAM);
In the BEGIN_MESSAGE_MAP macro in mainfrm.cpp:
ON_MESSAGE(WM_DOSOMETHING,OnDoSomething)
In the implementation for OnDoSomething:
LRESULT CMainFrame::OnDoSomething(WPARAM,LPARAM)<br />
{<br />
m_wndToolBar.GetToolBarCtrl().EnableButton(ID_EDIT_COPY,FALSE);<br />
m_wndToolBar.RedrawWindow();<br />
return 0;<br />
}
In your view class:
void CWhateverView::OnUpdateEditCopy(CCmdUI* pCmdUI) <br />
{<br />
if (m_bDisable)<br />
pCmdUI->Enable(FALSE);<br />
else<br />
pCmdUI->Enable(TRUE);<br />
}
In your function for long operation:
void CWhateverView::OnEditCopy() <br />
{<br />
m_bDisable = TRUE;<br />
BeginWaitCursor();<br />
AfxGetApp()->GetMainWnd()->SendMessage(WM_DOSOMETHING);<br />
int i, j,k;<br />
for (i = 0; i < 10000; i++)<br />
for (j = 0; j < 10000; j++)<br />
for (k = 0; k < 5; k++)<br />
{<br />
}<br />
m_bDisable = FALSE;<br />
}
And don't forget to declare m_bDisable in CWhateverView.h and initialize it as m_bDisable = FALSE; in the class constructor.
this is this.

Thanks so much for your explaination and sample. It reall helped me.
One question is : when I do BeginWaitCursor() it shows the hourglass for a fleeting second and again changes back to the arrow cursor. It does not stay as hourglass for the entire lengthy operation. Any help how to fix that?

every type of application can be content what you want,but more important is that you should write a derived class from CButton(for example),and override some virtual methods and message-functions.
