Well, what you need to do is set up a 2 dimensional array to hold your board, and then step through the possible sequences that indicate success. I guess you could do it in a one dimensional array of nine elements as well, but either way, you need to check each winning sequence to see if they all have the same value.

Keybd_event() is too weak for my needs. Certain programs it doesn't work with. I can't figure out syntax for using Sendinput(). All I want is example code that sends "H" to "Untitled - Notepad"...

UGH, I am 97% done with an application and I get stuck on this, I spent 10 hours already trying to figure it out. I even tried learning assembly to stuff the keyboard buffer, but I couldn't find any websites using the Alpha Assembler.

As it's a W98 on function, it won't work unless you have a Microsoft SDK installed.

I use windows 98, so would I be wrong to assume that its already instealled... How can I check if its in or not?

Totally wrong. The SDK is released four times a year by Microsoft. Just search the site for Platform SDK. It's up to date headers and library files, etc. for developers, there is no need for an end user to have them and they do not ship with any OS.

You also need to free the BSTRs before storing new values in them. So in get_Property:
SysFreeString ( *pVal );
And in put_Property:
SysFreeString ( bstrProperty );

I believe it's ok to pass NULL to SysFreeString(), but it wouldn't hurt to put in some standard pointer error-checking as well.

Check out the KB article "INFO: Where the Time Zone Information Is Stored" (MS's site looks to be down ATM so I don't have the article number). It says --

The time zone information is stored at the following locations:

On Windows NT:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Time Zones

On Windows 9x:
HKEY_LOCAL_MACHINE\Software\\Microsoft\Windows\CurrentVersion\Time Zones

Hi there,

I am trying to find a text in a window. For example, I am trying to find if an open Notepad contains a specific text or not. This works for simple windows, like Notepad and Message boxes. However, when I try to find a text in Internet Explorer, Visual Studio or MS Word, it does not work.

How can I find a text in a window? What's wrong with the following code?

Thank you very much for any helps in advance.

<br />
bool FindText (HWND hwnd)<br />
{<br />
	if (pWndOp == NULL)<br />
		return false;<br />
<br />
	bool bResult = false;<br />
	LPARAM lParam = (LPARAM)(&bResult);<br />
	EnumChildWindows (hwnd, (WNDENUMPROC)EnumChildProc, lParam);<br />
<br />
	return bResult;<br />
}<br />
<br />
BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam)<br />
{<br />
	if (hwnd)<br />
	{<br />
		TCHAR szTemp [1024] = {_T('\0')};<br />
		<br />
		SendMessage (hwnd, WM_GETTEXT, sizeof(szTemp) / sizeof(TCHAR), (LPARAM)szTemp);<br />
		<br />
		CString sText (szTemp);<br />
		if(!sText.IsEmpty ())<br />
		{<br />
			if ( sText.Find (pWndOp->m_sText, 0) != -1)<br />
		        {<br />
				*((bool*)lParam) = true;<br />
				return FALSE;<br />
		}<br />
        	}<br />
		//if(FindText (hwnd))<br />
		//{<br />
		//	*((bool*)lParam) = true;<br />
		//	return FALSE;<br />
		//}<br />
		return TRUE;<br />
	}<br />
        else<br />
		return FALSE;<br />
}<br />

You're looking for text in the window title bar, or in the main edit area ? I would have thought that doing this for a title bar would work for any program, but if it's the latter, then you're obviously going to need to get a handle on the child window that is the actual edit area, and check that.

I am looking for the text in the main edit area. So, I am enumerating all child windows and get the text in it.

However, this approach does not work with complex programs, like MS Word and VS. I get the text of the toolbars and combo boxes, but I cannot get the text of the main writing area.

Ah, you're enumerating CHILD windows. I'd suggest the relationship in a more complex app is a little more, well, complex, than one main window with a couple of direct children, hence your problem. Try doing it recursively and see how you go.

A program like MS Word or VS does not use standard windows components (ie edit box, listbox, etc.) to display text. Standard windows components do not handle custom drawing such as tables, embeded graphics etc. If you want to get the text from a program such as MS Word then you'll have to use OLE Automation.

Getting a combobox in a listview subitem??

mhowes27-Oct-01 10:04

I can't seem to draw a combobox in a listviews subitem. The combobox sizes funny.
The width and position end up correct but it ends up way to high.

I get the rectangle of the subitem just fine

GetListCtrl().GetSubItemRect(pNMLV->iItem,1,LVIR_LABEL,itemRect);

then I create the combobox with the rectangle info...

CPropListCombo *pPropCombo = new CPropListCombo;
pPropCombo->Create( WS_CHILD | WS_VISIBLE | CBS_DROPDOWNLIST | WS_CLIPCHILDREN,itemRect, this, 200 );
pPropCombo->ShowWindow(SW_SHOW);

correct position, and width but it's height is way to big....maybe double the size of what's in the CRect. I tried subtracting a large amount from the itemRect.bottom but it made no difference.

I do the SAME thing with a CBotton and a CEdit and it works fine....there isn't some minimum size for a combobox is there?? This is just CComboBox

thanks
mike

I think you have to get a pointer to the edit window of the combobox instead of the drop-down window. You're resizing the wrong thing.

putting information into controls that are in a CPropertyPage????

DanYELL27-Oct-01 5:40

DanYELL

27-Oct-01 5:40

I am going bonkers. I received a handful of responses which I printed out, but I still can't get
this to work.

I call a modal property sheet with two (2) property pages. I use the following code:

CPropertySheet sheet("PropertySheet");
CPropertyPage1 Page1;
CPropertyPage2 Page2;

sheet.AddPage(&Page1);
sheet.AddPage(&Page2);

sheet.SetActivePage(1);
sheet.SetActivePage(0);

if (sheet.DoModal() == ID_OK) { }

I have single and multiline edit boxes, check boxes, and a CListBox in the property pages. If I
type the following before I call DoModal():

Page1.m_edit1 = "hello";

I have no errors. For the single line edit box, this text appears. If I try putting text in a multiline
edit box or a simple combobox by typing say:

Page1.m_combo.SetCurSel(3);

I get a debug assertion error because m_combo is null or the multiline edit box is null.

I tried typing something like:

CWnd *pWnd;
pWnd->GetDlgItem();

then using SetWindowText(), but this doesn't work either.

SO MY QUESTION IS: How can I fill edit controls,
like a multiline edit box, a combo box, or
list box, in a property page before
calling DoModal()?????

Please, please, any response any one can give me will be greatly appreciated.

Sincerely,
Danielle (an overworked graduate student)

Page1.m_edit1 = "hello";

this fails for a multi-line edit? assuming m_edit1 is a CString that you've DDX'd to an actual edit control, it should just work.

You can't, not if those controls belong to and are instantiated by the dialog box you are calling the domoal for. You cannot use a window *as* a window before the window is instantianted. You *can* preload values before the domodal and than, in the initinstance method, for example, load the instantiated controls with those values.

How can I fill edit controls, like a multiline edit box, a combo box, or list box, in a property page before calling DoModal()?

You can't, because the control windows haven't been created yet. The correct place to set up controls is OnInitDialog(). At that point, the windows have been created but not yet shown.

Getting console cursor position?

Hi,
How can I get the position of the cursor in a console app?
I use 'SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), &coord)' to set the position, but there seems to be no 'GetConsoleCursorPosition' function.

Thanks in advance!
