Are you sure you have not loaded an Unicode string in your CString while compiling in non Unicode mode ?
~RaGE();
|
|
|
|

You options need to be set to show Unicode strings... In VC6.0:
Tools menu
Options...
Debug Tab
Display Unicode Strings
Peace!

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 ?
~RaGE();

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

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.
