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 !

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?

Here's one way using Word Automation:

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!

Try:

temp = new int;<br />
*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[^]
