From memory, a negative lfHeight means "points" as opposed to pixels, but you'd have to check the definitions on msdn for LOGFONT.

Your questions is not really clear.

You can see the mouse state Using GetKeyState function. You can know the mouse position using GetCursorPos

Check if this helps?[^]

I use WinInet + MFC to post some form to the web server.

I add the log module, at last found this:

1. call CInternetSession::GetHttpConnection
2. call CInternetSession::OpenURL
3. call CHttpFile::SendRequest
4. call CHttpFile::QueryInfoStatusCode (block)

at the step 4, some computer is ok, but some computer is block here.

when is block , the last error code:12002 ,it means time out.

I search in this web and google, but usually saied that's the WinInet's bug.

What should I do?

I have a CFormView with a large bitmap of a form.
I lay an edit box on top of the form where the user would
type in a value.

The image of the form has a vertical line that separates the
cents from the dollars. The edit box, even though its white
or light shaded, covers or blocks that vertical line of the
form. How can I make the edit box see-through so that you
still see the background of the form in the edit box?

I tried making the edit box transparent or the bitmap transparent
or one transparent and the other not and no combination is
working.

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

Sincerely,
Danielle

What about two edit boxes, one for dollars and the other for cents? Or, what about adding the vertical line to the edit box?

I thought about that. Two edit boxes just complicates it. You type in a
number 1234 and then tab off to type in the cents. Its faster to just type
in the number as is.

I thought about adding a vertical line to the edit, but have not figured out
a nice, simple, clean way of doing that.

I found a program on the web that looks like it has the feature Im looking
for. Its just a simple edit box and you can see the form in the background
of that edit.

If you know how to draw that line in the edit box, that would be great.

I am not sure what this has to do with C++; I suggest you move it to the Database forum.

Does Oracle expose an API that you can use for this?

I wouldn't think that was generally possible.

It also depends on what "corrupted" means.

And for a small database I wouldn't think the cost (time to implement) wouldn't be worth it for the product and for a large database it would not only take a long time but I wonder what the app is going to do then?

Setting RTL for a window?

Hans Dietrich7-Jun-11 16:27

According to MSDN, using SetProcessDefaultLayout(LAYOUT_RTL) should change the layout to right-to-left. However, it does not change the window caption - the buttons are still on the right.

I have found that using the extended style WS_EX_LAYOUTRTL does move the caption buttons to the left.

Is this how SetProcessDefaultLayout() is supposed to work? Or is there another API that will move the caption buttons to the left?

While WS_EX_LAYOUTRTL does work, it means that each window creation has to be intercepted and this flag added. I was hoping to find some way to do it only once, when an app starts.

Thanks for any suggestions.

Best wishes,
Hans

Thanks for that link, but as I said, SetProcessDefaultLayout() doesn't have the same effect as WS_EX_LAYOUTRTL, which Chen fails to mention.

Anyways, you could try hooking CreateWindow for your application OR register a windows hook for your process and catch the WM_CREATE message and try to add the WS_EX_LAYOUTRTL flag to created windows using ModifyStyleEx (don't know if it can be modified at runtime).

Win32 Buttons, which is which? [solved]

Groulien7-Jun-11 8:56

Hello everyone,

I've been experimenting with C++ and how to build a form with it (without MFC).
I've created two buttons at runtime with the following code:
(I used a bit of copying and pasting)

if (button1 == NULL)
{
	button1 = ::CreateWindowEx(WS_EX_LEFT,L"button",L"Button1", WS_CHILD ,50,50,50,50,parent,NULL,::GetModuleHandle(NULL),NULL);
	SendMessage(button1, WM_SETFONT, (WPARAM)defFont, MAKELPARAM(TRUE, 0));
	::ShowWindow(button1,SW_SHOW);
}
if (button2 == NULL)
{
	button2 = ::CreateWindowEx(WS_EX_LEFT,L"button",L"Button2", WS_CHILD ,125,50,50,50,parent,NULL,::GetModuleHandle(NULL),NULL);
	SendMessage(button2, WM_SETFONT, (WPARAM)defFont, MAKELPARAM(TRUE, 0));
	::ShowWindow(button2,SW_SHOW);

}

There's no problem with building the buttons, this is my WndProc:

C++

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
	switch(msg)
	{
		case SW_SHOW:
			break;
		case WM_COMMAND:
			if (wParam == BN_CLICKED)
			{
				Triggered(L"1"); //Shows a messagebox.
			}
			break;
		case WM_SHOWWINDOW:
			Init(hwnd); //Builds the buttons here.
			break;
		case WM_CLOSE:
			DestroyWindow(hwnd);
			break;
		case WM_DESTROY:
			PostQuitMessage(0);
			break;
		default:
			return DefWindowProc(hwnd, msg, wParam, lParam);
	}
	return 0;

}

How can I tell which one sent the message?
--

Nevermind, got it.
lParam equals with the (LPARAM)handle of the button that sent it.

When you call CreateWindowEx, the return is a handle to the button, that same handle can be used within the WPARAM or LPARAM to distinguish, or alternatively, if you have two button and you must distinguish, then they should probably be sending different messages.

Another way is to create button window with id.

button1 = ::CreateWindowEx(WS_EX_LEFT,L"button",L"Button1", WS_CHILD ,50,50,50,50,parent,(HMENU)100,::GetModuleHandle(NULL),NULL);

button2 = ::CreateWindowEx(WS_EX_LEFT,L"button",L"Button2", WS_CHILD ,125,50,50,50,parent,(HMENU)200,::GetModuleHandle(NULL),NULL);

Now you can distinguish which is which.
case WM_COMMAND:
if ((UINT)HIWORD(wParam) == BN_CLICKED)
{
switch (int)LOWORD(wParam):
{
case 100:
Triggered(L"1"); //Shows a messagebox.
break;
case 200:
Triggered(L"2"); //Shows a messagebox.
break;
}
}
break;

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