Have a look at ITDigitDetectionEvent in MSDN or on the platform SDK.

CToolbar problems in Win98 2nd Edition?

dazinith1-Jul-02 10:29

Hio.. I have 2 win98 machines that are having major toolbar problems.. I am using the following little function to switch out the toolbar:

void CMainFrame::SetToolbarDefault()
{
	// setup buttons on toolbar, and text labels
	m_wndToolBar.SetButtons(NULL, 3);
	m_wndToolBar.SetButtonInfo(0, ID_OPTIONS, TBBS_BUTTON|BTNS_SHOWTEXT, 0);
	m_wndToolBar.SetButtonInfo(1, ID_APP_ABOUT, TBBS_BUTTON|BTNS_SHOWTEXT, 2);
	m_wndToolBar.SetButtonInfo(2, ID_EXITBTN,TBBS_BUTTON|BTNS_SHOWTEXT, 3);
	m_wndToolBar.SetButtonText(0,"Options");
	m_wndToolBar.SetButtonText(1,"About");
	m_wndToolBar.SetButtonText(2,"Exit");
	
	// invalidate the call update handlers before painting
	m_wndToolBar.Invalidate(TRUE);
	m_wndToolBar.UpdateWindow();
	Invalidate(TRUE);
	UpdateWindow();
}

i have another function which is basicly the same which switches the toolbar to a different set of menus.. both have the following problem:
as soon as the SetToolbarDefault()gets called the menus become grey.. and they dont ever redraw.. if you move the window around, the area where the toolbar should be is all distorted, showing other things behind where the toolbar should be.. its like it never gets redrawn again, ever, until i exit the program and re-enter..

plz keep in mind that these buttons do have handlers, and they are not just greyed out as if they didnt have a message handler.. also these menus work fine under win 2000.. plz tell me someone has an idea on this one? Confused | :confused:

RichEdit scrolling

Hi, i want to let me richEdit control scroll to the very bottom whenever new text is added. Most examples here use LineScroll(1) to scroll down by 1 line whenever text is added but when your richedit has the style WS_HSCROLL turned off, then whenever the text is longer than the window width it'll need to scroll down more than one line...
I can't just do LineScroll(5) or anything like that either cause then it'll scroll down till the last line is at the top of the control, and thats not pretty either now is it..

Any ideas?
thanks.

P.S.: LineScroll doesn't even seem to work under WIN2000, i'd like to have something that works under WIN2000/WINXP as well

I found this works:

// Give it focus
theApp.m_hwndPWOutputWindow->GetRichEditCtrl().StreamIn(SF_TEXT | SFF_SELECTION, es);

// Send some keys to cause it to move right to the bottom <-,->
theApp.m_hwndPWOutputWindow->SendMessage(WM_KEYDOWN,37,0);
theApp.m_hwndPWOutputWindow->SendMessage(WM_KEYDOWN,39,0);
if(!gbTalk)
{
theApp.m_hwndPWOutputWindow->SetFocus();
theApp.m_hwndPWOutputWindow->UpdateWindow();
}
theApp.m_hwndPWOutputWindow->UpdateWindow();

Your in luck a project of this type has receintly been submitted to code project. You can find it at http://www.codeproject.com/audio/cximagemng.asp. It is a bit much to go through but boy the things you can learn from this source.

if what I gave you in the first post is more than you were looking for try something a little simpler.
Like this

LVBKIMAGE lv;
ZeroMemory(&lv, sizeof(lv));
lv.ulFlags = LVBKIF_SOURCE_URL | LVBKIF_STYLE_NORMAL;
lv.pszImage = szFileName;
lv.cchImageMax = lstrlen(szFileName);
ListView_SetBkImage(hndLVCtrl, &lv);

I keep getting this message every time I double click an object to add code for it.

Any ideas on what may cause this or how I can fix it?

Thanks

are you trying to add a message handler, or a variable? (this is in the resource editor right?)

my guess is its caused by VS6 not being able to interpret your .cpp file..
Modified when adding variables:

void COptions1::DoDataExchange(CDataExchange* pDX)
{
CSAPrefsSubDlg::DoDataExchange(pDX);
	//{{AFX_DATA_MAP(COptions1)
	DDX_Text(pDX, IDC_DATAPATH, m_strDataPath);
	//}}AFX_DATA_MAP
}

Modified when adding message handlers:

BEGIN_MESSAGE_MAP(COptions1, CSAPrefsSubDlg)
	//{{AFX_MSG_MAP(COptions1)
	ON_BN_CLICKED(IDC_BROWSEBTN, OnBrowsebtn)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

if you took out or modified the AFX_MSG_MAP or AFX_DATA_MAP parts then VS6 wont be able to figure out where to put the code.. you can add it manually if you look at examples of how the class wizard has been doing it for you..

hope that is what you were looking for!

Class disappears from class view

I have a class that I just deleted a couple of buttons from and then all a sudden the class disappears from the class view.

The class still compiles and everything works as if nothing is wrong....just can't access it from the class view.

I tried cleaning the project and deleting the .clw file...nada

Any idea on how to get it back?

Thanks for any help

Re: Class disappears from class view

1-Jul-02 9:40

When this happens, I go to the file view, open the class's header file, and make a temporary change, to force the file's "modified" flag to be set. Remove the change and hit "Save". The Class magically appears in Class view!

two documents in an MDI project

ns1-Jul-02 8:54

1-Jul-02 8:54

Heres what I am trying to do:

I create two different documents in an MDI project. Its a CFormView based project and each view is to be associated with a different dialog resource. On the fly I want view1 to spawn view 2 (or make it topmost if it already exists). Ideally I want the app to start with both documents (and associated views) created, but the hidden one comes to the top when the top one tells it to. Then the user calls a dll which returns some info. I want to give this info to view1(or document1), and bring view1 to the top again, hiding view2.

CAn this be done? What do I need to do? ANy pointers (haha) would be greatly appreciated. Also, my first view apwans a login dialog (modal) which is to return the password successful info to view 1 so that certain menu items get enabled in view1. What do I do here to pass this information?

Thank you very much,
ns Unsure | :~
