I have 10 set of x and y values..i have to draw graph for this 10 values..
anybody can give sample code for drawing graph in MFC...i need a sample code..
Pls help me..
|
|

Just giving a simple process
This is the drawing method
<code>
INT nY1 = LPtoDP(AXIS_Y, dblDataY.GetAt(0));
INT nX1 = LPtoDP(AXIS_X, dblDataX.GetAt(0));
pDC->MoveTo(nX1, nY1);
for (int i=0; i < dblDataX.GetCount();i++)
{
INT nY2 = LPtoDP(AXIS_Y, dblDataY.GetAt(i));
INT nX2 = LPtoDP(AXIS_X, dblDataX.GetAt(i));
pDC->LineTo(nX2, nY2);
}
</code>
besides this you need two additional funtion for converting form actual data to sceen coordinate and vise versa
<code>
LPtoDP( AXIS_TYPE AxisType, DOUBLE dblData)
{
switch(AxisType)
{
case AXIS_X:
nPos = (INT)(m_dblOrgX + ( dblData * m_dblScaleFactorX ));
break;
case AXIS_Y:
nPos = (INT)(m_dblOrgY + ( dblData * dblScaleFactorY ));
break;
default:
return 0;
}
return nPos;
}
</code>
DPtoLP( AXIS_TYPE AxisType, DOUBLE dblData )
{
switch(AxisType)
{
case AXIS_X:
wdPos = (WORD)( (dblData - m_dblOrgX) / m_dblScaleFactorX);
break;
case AXIS_Y:
wdPos = (WORD)((m_dblOrgY - dblData) / m_dblScaleFactorY);
break;
default:
return 0;
}
return wdPos;
}
And also find minmum and maximum of all the data and use this to calculate the scale factor
CalcScaleFactor( CRect rctDrawArea )
{
DOUBLE dblScaleRangeX = m_dblScaleMaxX - m_dblScaleMinX;
DOUBLE dblScaleRangeY = m_dblScaleMaxY - m_dblScaleMinY;
m_dblScaleFactorX = ( dblScaleRangeX == 0 ) ?
0 : (DOUBLE)rctDrawArea.Width() / dblScaleRangeX;
m_dblScaleFactorY = ( dblScaleRangeY == 0.0 ) ?
0 : (DOUBLE)rctDrawArea.Height() / dblScaleRangeY;
m_dblOrgX = rctDrawArea.left - ( m_dblScaleMinX * dblScaleFactorX );
m_dblOrgY = rctDrawArea.bottom + ( m_dblScaleMinY * dblScaleFactorY );
}
}
There are some member variables in the code you can understand by close look at the code. Just simple of drawing graph is convert your points to screen coordiante and then simple line draw between points.

Hi. To obtain an horizontal scrolling text, I created a transparent window on which I move a text. After I set the windows as TOPMOST, so my application can show messages like a TV. The problem is that sometimes, other applications create a TOPMOST window too. So, using a timer, I look if my window is on top; if not I call:
if ((WindowOverMine = GetWindow(myWindow, GW_HWNDFIRST)) != myWindow)
SetWindowPos(myWindow, WindowOverMine, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
In this way everything works fine... only a problem... I can't click another window or menu of my application... I think because the transparent window is ALWAYS over the others. It doesnt'happen with other application windows . Have you a suggestion ??
Thank you !

Why don't you set a region for your transparent window to have the holes in places where your menu should be clickable?

Hi
I have a drag drop handler. When i drag drop a file to a network path. I am getting the path like this "C:\Documents and Settings\720452\NetHood\Temp - infch01152\新規Microsoft Word Document.doc". But the share name is \\infch01152\temp. Is there any way by which i can get the original path from the path mentioned above. Thanks in advance.

Greetings,
I would like to retrieve the whole document text from an active text window in Visual Studio 98.
For now I select all text and retrieve it via TextSelection (language: C++). Here the pseudo code:
...<br />
TextDocument doc = getActiveDocument();<br />
rememberCurrentSelection(sel);<br />
TextSelection sel = doc.getCurrentSelection(); <br />
<br />
sel.selectAll();<br />
wstring wholeText = sel.getText();<br />
<br />
restorePreviousSelection(sel);<br />
...
Drawbacks:
o Selection of all Text causes flicker effects
o Restauration of previous text selection often will change scroll position
Is there any way to retrieve the text without these drawbacks?
Thank in advance,
Jacek

If you have a handle on the window, you should be able to get the text easily, no ?

GetWindowText() will return NULL for the desired window, already tried.

Hi,
I have been thinking about the problem below for a week  , Is there anyone can help me?
I m working on a MFC program, and I want to make the program support console (Command Line). I don't know why I can't use cout or printf to print anything out. I thought It could display messages on console when I launch the program on console (windows xp), like:
c:\app.exe -number 1
but nothing came out on consle actually. I know that I can create another console to recieve messages from cout and printf, but I don't want to create any console in my program, I just want print some message on original console. In Java, we can print message on console by using System.out.print(), so is there any way, function or class I can use to print messages on the console in MFC program? Could you show me a simple example?
Thanks so much!

Everything is a bit mixed up in your post.
- A console program does usually not involve any mfc. It is a program that usually does not have any GUI and in which you can use cout and cin.
- An MFC application is an application using classes that makes it easy to handle the GUI.
Both are seldom mixed together.
- A command line is a set of parameter you can give to your executable, no matter if it is a console application or a MFC app, it works in both ways.
c:\app.exe -number 1
David.YueZuo wrote: nothing came out on consle actually
What did you expect here ? How are you handling the command line in your application ?
David.YueZuo wrote: I can use to print messages on the console in MFC program
As I explained, MFC and console are usually different types of app. If you want to display something in a MFC app, use a CEdit, a CStatic or a MessageBox.

Thanks so much for your infor.
Here,
c:\app.exe -number 1
app.exe is just a MFC program (GUI-Based), I added some printf statements in it, like printf("Hello, world"), I hope this "Hello, world" can be displayed on my console. Actually, I used CEdit, CStatic and MessageBox as well, but only if I want the messages to be displayed on a dialog, editor.
In Java, we can have:
{
......
JOptionPane.showMessageDialog("Hello World");
System.out.print("Hello World");
......
}
then, message "Hello world" will be displayed on two different places, one is on a dialog, another is on the console. I want to use the same way to deal with messages in MFC. Could you tell me how to do?
Thanks

A GUI program is usually not connected to a console. On your windows dektop, you may have 0 to many consoles, so which one would you like to send your messages to? Like you said yourself, you can allocate a console to your application using "AllocConsole ()" When you do that, then your printf statements will send their output to this console.

Now, I open a console by using "run" -> "cmd", type the directory of the file, then run my program on this console like:
c:\cd temp
c:\temp\app.exe -number 10
Again, app is a GUI-based MFC program, I added some printf statements in it, like printf("Hello world"); or std::cout << "hello world"; I hope the message "Hello world" could be displayed on my current console. Could you tell me how to do?
Thanks!

As said before, your app and the console are two separate programs. If you start your MFC application from a console, then this application will start independently of that console. I.e., the two will not be connected! The only way is to allocate a console window to your application with AllocConsole. For as far as I know, it is not possible to connect an existing console to you MFC application.

This is difficult. As I already explained, MFC and console are two different kinds of application. I may even add that mixing both of them is extremely bad design, IMO  .
What are you trying to achieve exactely ? Why do you need a console aside your application ? Do you really think the user of your app wants to have a console pop up, or is this only for debugging purposes ?
This may be a start point:
QuickWin[^]
However, this is the opposite to what you need: make a console run as a plain Win32 application.

Actually, I was a Java programmer. In Java, we can use both ways to display messages, no matter on console or GUI. Now, I am a C++ programmer, I m trying to use the same way to create a GUI-based MFC program.
To create a console aside GUI for a actual user may not a good idea, but for the designer and programmer, it's a esaier and faster way to debug and monitor our program. In fact, I don't want to create any console, instead, I want to make the program able to run on console, and to recieve arguments from console. Also, program's messages would be displayed on current console during the running time.

You can use debug statements in your MFC application, using 'OutputDebugString()' (if i remember correctly). The strings supplied as an argument will be displayed in the 'Output' section of Visual Studio (assuming that you use VS ofcourse  ). You can also use an external debugging application that is able to capture output generated by 'OutputDebugString()'. You can use 'windbg' for example to receive the debugging output.

you may use a RichEdit Control to display debug info etc.
http://www.codeproject.com/richedit/RichEditLog_Demo.asp
In order to enable a kind of interaction through commands (and do not want to use button etc.) , you can embed (TCL, LUA, Python) in or develop a small scripting facility.
