This is a very generic question, but I'll give it a try:

1. Separate the data from the viewing of the same data...
2. use dynamic memory assignment if you don't know the amount of data that you'll need.
3. think about how many history do you need to maintain.
4. create a control derived from a CStatic called CGraph.
5. Override the OnPaint function of that control in order to draw the axis, the captions and the labels.
6. Draw each point depending on a scale factor.
7. if the graph needs to be scrolled, think about a scrolling bar... (think about drawing the part needed ni order to avoid to collapse too much the CPU)

Hope this helps...

I think you need to enable the "toolwindow" style (i.e. its equivalent in C#).

Allocating memory for a multidimensionnal array

Jerome Conus1-Jul-03 1:54

Hi !

I have a very basic question about C++ :

I want to allocate on the heap a two-dimensionnal array. I tried to do this :

int* pArray=new int[x][y];

but of course it didn't work, so I did that :

int* pArray=new int[x*y];

and each time I need to acces my array, I calculate the x/y position. It works, but still, I'm curious : is it possible to allocate memory in such a way that I can then use the usual notation for a multidimensionnal array : Array[x][y]=z.

Thank you for your help !
Jerome

int **pArray = new int*[x];
for(int i=0; i<x; i++)
   pArray[x] = new int[y];

This will let you use pArray[x][y] = z. To deallocate this array, do this:

for(int i=0; i<x; i++)
   delete [] pArray[x];
delete [] pArray;

Hope this helps,

Hi everyone!

I have to get the text from a ms word document (.doc) and save the text to a text file (.txt).
Have any of you guys done this? Or can you give me a hint where to start?

CString         strFileName;
_Application    app;
Documents       docs;
_Document       doc;
COleVariant     vtOptional((long) DISP_E_PARAMNOTFOUND, VT_ERROR),
                vtFalse((short) FALSE),
                vtTrue((short) TRUE),
                vtDoc((short) 0),
                vtText((short) 2),
                vtRtf((short) 6),
                vtHtml((short) 8);


if (app.CreateDispatch("Word.Application") == TRUE)
{
    docs = app.GetDocuments();

    m_ebDocName.GetWindowText(strFileName);

    doc = docs.Open(COleVariant(strFileName), vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional, vtOptional);

    strFileName.Replace(".doc", ".txt");

    doc.SaveAs(COleVariant(strFileName),
        vtText,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional,
        vtOptional);

    docs.Close(vtFalse, vtOptional, vtOptional);

    app.Quit(vtOptional, vtOptional, vtOptional);
}

About PINT

Here is a static PINT varible: temp.
I want to store the value "12" to *temp, and my program coded like below

static PINT temp;
* temp=12;

I can succeed in compiling it, but there is an error when running it:
The instruction at "0x00406a3a" referenced memory at"0x00000000". The memory could not be "written".

What is the problem? How can solve it?

Thank you in advance!

*temp = 12;

Obviously temp doesn't point to anything. You need to point it to an integer before attempting to dereference it.

I see, after seeing your explanation
Can I ask another question?

First I completet the below sentences:
PINT temp;
temp=new int;

Then I have a PVOID varible temp2,which is to be applied like
temp=(PINT)temp2;

Is it right after twice times of putting the pointer?
Thank you!

you might also do it that way:

<br />
wchar_t* wcStartTime = new wchar_t[MAX_SIZE_STRING_TIME];<br />
swprintf(wcStartTime, "%i:%i:%i", stStart.wHour, stStart.wMinute, stStart.wSecond);<br />

The values in the SYSTEMTIME structure are in no particular format. It's up to you to format them into a variable. For example:

char str[32];<br />
SYSTEMTIME st;<br />
GetSystemTime(&st);<br />
sprintf(str, "%02u:%02u:%02u", st.wHour, st.wMinute, st.wSecond);

The WIN32 api has some powerful functions for formatting SYSTEMTIME vars. See GetDateFormat and GetTimeFormat in the docs.

Hello,
I have a problem ... I want to capture the desktop and save it in a 24Bit bitmap ... my desktop can be 256, 16bit or 32bit color.
How can I do that ? It works fine if the desktop is in 24bit ... but I want to convert a HBITMAP from 256, 16bit, 32bit to 24bit ... I hope I will not have to convert it manualy by saveing it byte by byte .... I hope there is something in windows that can take care of it ... because I saw 15Bit color and God knows many these types can be and I hope I don't have to take care of all... Please if anone can help me... !!! thanks !!!

Check out a class by PJ Naughter called CDibImage. It does conversion to 24bit. Excellent class. http://www.naughter.com/dibimage.html[^]
