Re: CImageList / CComboBoxEx - what's wrong?

What does InsertItem() return?

suggestions:
1. you don't need invoke GetBuffer(0). you can use just Lock() and UnLock().
2. Clear COMBOBOXEXITEM before using by ZeroMemory().
3. set cchTextMax in COMBOBOXEXITEM

Sorry, that's not what I meant. What I meant was, did you insert the control into the dialog resource (in the dialog resource editor) as a standard combo box or an extended combobox?

I've just created a test dialog based project using the AppWizard, added an extended combo box to the dialog (and used the wizard to add a control variable for it), added a bitmap to use for the images and an image list member in the dialog, then copied and pasted your code into the OnInitDialog method and everything works perfectly.

Oh, I didn't see the icon for the extended combobox in my dialog resource editor toolbar. I replaced my old comboboxes with the new ones an now everything works fine Smile | :)

Thank you very much for your help! Rose | [Rose]

hi,

how can i control the position where to insert my text, or is it only possible to append new text?

(i want to insert lines at the beginning of the already inserted text)

thanks

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

Launching App by double-clicking on file

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 );
// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// Dispatch commands specified on the command line
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), // custom MDI child frame
    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.

Font dialog

Stew14-Jul-02 7:10

Stew

14-Jul-02 7:10

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.

Macromedia tool panels.

bisserke14-Jul-02 7:06

14-Jul-02 7:06

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

Do I need AfxGetMAinWnd to run a mainframe function from a view?

ns14-Jul-02 6:46

14-Jul-02 6:46

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

Re: Do I need AfxGetMAinWnd to run a mainframe function from a view?

ns14-Jul-02 6:55

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

How to sendmessage to view1 from view2

ns14-Jul-02 6:20

14-Jul-02 6:20

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

ns

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.

ns wrote:

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.

Horizontal Scroll Bar and CListBox

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? Confused | :confused:

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.

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!

Lucky2002

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
