how do l plot graphs in MFC

As stupidly it sounds, but Read old text, add your String to it, and write String back. For example

CString s;
MyEdit.GetWindowText(s);
s+='abcd';
MyEdit.SetWindowText(s);

It is a unique way. If you want to save caret position, do it manually. The better way is to write own heritable controls as CEditEx, CListBoxEx, and to place all needed routines like that into them. You will make it once and will be happy many years. Smile | :)

I think that's a good idea... CEditEx... Yes... I'll do that...
But I'll use (Nevertheless) this method:

MyEdit.SetSel(-2, -1);
MyEdit.Replace(MyText);

Thank you very much Big Grin | :-D

MDI Child Windows

Please Help, very little experience with MDI apps!!

I'm looking for information regarding opening, closing, initializing data, etc.. in an MDI application. I want to be able to open a child window and initialize the fields with data from other apps. I can currently open the MDI application and initialize it with the information in shared memory, but I would like to be able to keep the MDI app open and just open different child frames with the data that I send over from other apps. The opening my already defined view part is throwing me. I found and example on creating a new view but nothing on an already defined view.

Again I am new at MDI apps and looking for good information on dealing with the different child frames.

Thanks in advance for any help that you can provide.

Hi, l am writing a GUI using MFC, and l need to include some graphical features in it. Does anyone know how to plot graphs using MFC? All l need is something that plots points from a table of data, not from a function. It also doesn't need to be interactive -- basically l need just the most simple kind.
Any suggestions will be appreciated.
Thanks!!

I would like to write a routine to copy registry entries into an INI file then back into the registry, but the only functions I can find in CWinApp are WriteProfile and GetProfile. Does anybody know if there is anything built-in for this task or if it must be done manually??

Any suggestions are appriciated.

Thanks!

unfortunately, there is no any appropriate functions in MFC for your task.
Moreover, MFC does not include any routines for INI-support (as far as i know). You must do it manually, by WinAPI functions.

See in MSDN: RegOpenKey[Ex], RegCloseKey and so on for Registry operation

AND
GetProfileInt, GetProfileSection, GetProfileString etc. for INI-operations

I was afraid of that. Oh well, doesnt seem all that difficult to do manually so thats what ill do!
Thanks.

There is an another way to solve your problem. You may use regedit with command-line params for saving and loading your data from reg-file. Like that

regedit /e My.reg HKEY_CURRENT_USER\Software\My Data //From registry to file

regedit -s My.reg //From file to registry

You can use WINAPI - CreateProcess function to make this job silent

SetCursor Problems !

Hi again,

i call SetCursor(LoadCursor(NULL, IDC_WAIT)) in a (ListCtrl) Subroutine,
but the Cursor doesn't change.

How can i make it the right way ?

to change the cursor, you need to handle the WM_SETCURSOR message. this will give you a OnSetCursor function.

like this:

BOOL CPickAxeView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
	// make sure we only set the cursor if we're need to 
	if (pWnd==(CWnd *)this) 
	{
		if (nHitTest==HTCLIENT) 
		{
			if (message==WM_MOUSEMOVE) 
			{
				SetCursor(AfxGetApp()->LoadStandardCursor(m_cursor));
				return TRUE;
			}
		}
	}	

	return CView::OnSetCursor(pWnd, nHitTest, message);
}

-c

Thanxs,

i needed for the header of a listcontrol. If the cursor is over the header,
then the standard cursor is shown.
How can i catch the Listcontrol->Header->OnSetCursor routine ?

you'll need to create a class derived from CHeaderCtrl, override OnSetCursor there, then use that class on your list control.

Hi,

sorry for my stupid question, but how can i
"use that class on your list control" ?

i have a created a new Class with modified OnSetCursor(), and then... ?

Example code of 'NetMessageBufferSend'-function?

15-Jul-02 5:57

Yes.

Follow this path:

Project->Add to project->Components and controls->wait....->visual C++ components->splash screen.

You will get standard implementation of Splash screen.
