You could use SetSel(0,0) and then ReplaceSel("your text")
However, this is untested.

I want to be able to have my application open when I double-click on one of the files that the app creates. I modified my app to take in command line parameters and when I double click on the file, I guess it doesn't send any command line parameters and so the app won't open up. Anyone got any ideas about how to pass in the command line parameters to the application when double-clicking on the file?

Since the steps are a bit long, so create a temporary project (SDI or MDI).
Normally, you have to call these functions in that order:
EnableShellOpen( );
RegisterShellFileTypes( TRUE );
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
if (!ProcessShellCommand(cmdInfo))
return FALSE;
in your CYourApp::InitInstance(). You will also have to modify the
resource script for your document type. Let's say you have a MDI App.
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(
IDR_MYAPPTYPE,
RUNTIME_CLASS(CMyAppDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyAppView));
AddDocTemplate(pDocTemplate);
You need to change IDR_MYAPPTYPE resource string to match the extension of your application. The extension is the string just before MyApp.Document.
Like I said, the steps are a bit complex and long but this should get you to start.

I want to have a font dialog in my application and I'd like to use the CFontDialog from MFC but I don't need things like a script selection box and a preview box on mine. I tried just using the flags to turn off those parts that I don't plan to use or have in my dialog, but the dialog looks like crap because the script dropdown is still there, it's just greyed out etc... All I need is the three list boxes for font, font type, and font size. Does anyone know of a way to get rid of that stuff from the CFontDialog class or do I need to create a new dialog that is specific to my needs? If I have to create a new dialog, is there a method I can use to populate the three list boxes with the same data that is populated in the list boxes on the CFontDialog dialog?

Look at EnumFontFamilies, you can use the LPARAM to pass your combobox or dialog pointer. Last check nFontType to filter only for font type that you need.

You can use a custom template. You just have to specify the CF_ENABLETEMPLATE flag.
CFontDialog cfd (&MyLogFont, CF_ENABLETEMPLATE |...);
cfd.m_cf.hInstance = AfxGetInstanceHandle();
cfd.m_cf.lpTemplateName = MAKEINTRESOURCE(IDD_MYFONTDIALOG);
When you create your template, just leave off the controls you don't want, and make sure you use the correct IDs for the controls you want to keep.
Control ID
Font Combo Box 1136
Font Style Combo Box 1137
Size Combo Box 1138
OK Button IDOK
Cancel Button IDCANCEL
Help Button 1038
Sample display box 1092
Comment box 1093
This might be an incomplete list, and the numbers might be defined in some header file somewhere, but this should get you going.

Hi,
I'm trying to create tool panels like the ones macromedia uses.
I tried it in 2 ways:
1) With CDialogBar derived classes.
This way they allways have the same focus as the parent frame (CMainFrame), but I can't catch
any WM_MOVING or WM_WINDOWPOSCHANGING messages. I need these to make them 'snap' to the borders.
2) With modeless dialogs.
Now I am able to make them snap to the borders, but they do not have the same focus as the main
frame.
Does anybody know how I can catch moving messages in the DialogBar or how to make sure that a modeless dialog has the same focus as its parent ?
would be very happy if someone could help me out cause I'm at the end of my knowledge.
thx

I have a mainframe function that I want to run from a view. how do I do this? How to get a pointer to the mainframe? What it will do is switch to view2 from view1 when i call it from view1.
Can I do AfxGetMAinWnd->SwitchView from class view1?
Thanks,
ns

Actually,
I tried
void CFormViewMDIView::OnButton1()
{
CRuntimeClass* pViewClass = RUNTIME_CLASS( CForm2View );
if ( pViewClass == NULL ) return;
CMultiDocTemplate* pTemplate = theApp.m_pView2Template;
if ( pTemplate == NULL ) return;
AfxGetMainWnd->SwitchView( pTemplate, pViewClass );
}
and it doesnt like AfxGetMainWnd->SwitchView( pTemplate, pViewClass );
Error is:
C:\Trainer\FormViewMDISwitch\FormViewMDIView.cpp(157) : error C2227: left of '->SwitchView' must point to class/struct/union
SwitchView is a mainframe function.Helllpp

|

|

Yes... but it's :
AfxGetMainWnd()->SwitchView(...)
You've omitted "()" after AfxGetMainWnd... I think...

I only have two views in my project. I need to send a user defined message from view2 to view1. How do I get the pointer to view1 which I need in doing pView1->SendMessage (..) from view2 ( If I've understood the senddmessage correctly). Is the view currently on top in the mdiframe the active view? In that case I'm sending a message from my active view (view2) to view1 which isnt active, and understand that I need a pointer to the view the message is going to.
A side question:
Is it possible to send a message from the doc to an inactive view that will make it active? Does it make sense to send a message to an inactive view? Is it legal?
another question. Lets say I have a SwitchView function that lets me switch from one view to another. Now if In my active view i say
SwitchView;
dosomethingelse;
will dosomethingelse get executed? Or is anything after switchview ignored because the view is not active anymore..?
Thanks

Yup! I don't think that code execution in the view will be impacted in any way by the activity state of the associated view window object.

Yup again, IMHO. (The sense of course depends on your goal an your application). As you can send messages to inactive windows (I think the "activity" of a window is only important regarding keybord input) via API you can send them to inactive views using MFC as well!
ns wrote:

You could get a pointer to the doc object from one view, and then enumerate all the documents views and call SendMessage on them.

Hi...
If I want to use methods of CMyView via CMyDoc, I must to have a pointer to CMyView!!! How??? And is this logic to do that (does anybody do it)???
Is this a clean solution :
CMyView* pView = (CMyView*)m_viewList.GetHead();
Thanks

Hello @all!
I have got a CListBox and added a horizontal scroll bar.
Now my question: How can I get the lenght of my ListBox? 
The lenght of my string can I get through:
m_ctrlListBox.GetTextLen(0);
Correctly?

m_ctrlListBox.GetCount() will return an int for the number of items in the control or LB_ERR if an error occurs.
|
|
|
|
|
I´m sorry, my mistake:
I want to know the width of my ListBox.
Lucky2002
|
|
|
|

Ah! Okay, I'm not sure if I know what you're asking but...
Use m_ctrlListBox.GetHorizontalExtent() to get the scrollable width of the list box, in pixels.
If you just want to know the screensize of the ListBox, use...
CRect rect;<br />
m_ctrlListBox.GetClientRect(&rect);<br />
rect.DeflateRect(CSize(GetSystemMetrics(SM_CXEDGE), GetSystemMetrics(SM_CYEDGE)));<br />
iWidth = rect.Width();

Hi!
Thank you very much! I needed the last one.
Now I have another question and hope you can help me:
I need the lenght of the strings in the ListBox. When I use
m_ctrlListBox.GetTextLenght(0)
I only get the number of variables without the blanks between the words.
Thank you!

Call CDC::GetTextExtent() on each string as you add them to your list control, and keep the width of the widest string as the width of your listbox.
int width = 0;
CSize size (0, 0);
CDC *pDC = m_listbox.GetDC();
int saved = pDC->SaveDC();
pDC->SelectObject(GetFont());
while (ThereIsAStringToAdd)
{
m_listbox.AddString(TheStringToAdd);
size = pDC->GetTextExtent(TheStringToAdd);
width = width > size.cx ? width : size.cx;
}
pDC->RestoreDC(saved);
ReleaseDC(pDC);
m_listbox.SetHorizontalExtent(width + 5);

I'm working on a Dialog-based project. The app, as usual, starts my dialog class with DoModal(). However, I sometimes want the dialog to start hidden, depending on calculations done in OnInitDialog(). I know how to use ShowWindow() but where do I control whether the dialog will *start* visible or hidden?
|
|
|
|
|
Mike Dunn's C++ FAQ, §7.6, shows how to have a dialog hidden at start-up. I guess you can adapt the technique to your needs.
