How to use Tokenize() wid CStrings in VC6 - C / C++ / MFC Discussion Boards

Thanks,

Actually I was trying to simulate the output of a load after asking for an input and a current value(in amps) and I'm suppose to get like 0 and 0.5.
But the device kicks out 0'\xDB''\xDB'0.5'\xDB''\xDB'
instead of 0 0.5 .
And sscanf doesn't know what to do with '\xDB'.
I need to just get the 0 and 0.5.

Unless you know exactly how many numbers you will have in there, sscanf isn't a wise choice. You can have strtok do it for you, but the CString::Replace method will work and look cleaner.

If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

Right, sscanf() does not handle multibyte hexadecimal characters.

Hi,
I am not able to use Tokenize() method wid CString objects in my VC6 application while same code was compiled successfully in VC.Net.

int curPos = 0;
CString resToken = strDecimalWords.Tokenize(" ",curPos);
while strDecimalWords which is CString object,contains "1 hundred 23".

but VC compiler is showing this compile time error.
f:\advivr\ivractionmanager.cpp(495) : error C2039: 'Tokenize' : is not a member of 'CString'
Can anyone suggest wat to do.

Regards

Cyber Friend

Since the Tokenize member function was not yet defined in older MFC library, you have to solve the problem in a different way. I think you have to deal with a series of Find(" ") member functions combined with Mid(...), in a loop.

You can use AfxExtractSubString() in VC 6.

FillRect with CBrush question

Hi!

When I call FillRect with a brush created from a bitmap, the rect will get filled but the bitmap is tiled, even though the rect and bitmap size are the same (20 X 20). Is there a reason for that? I thought the bitmap would get displayed correctly!

Screenshot at www.edovia.com/pictures/FillRect.png[^]

<br />
//Draw thumb<br />
    RECT rectThumb;<br />
<br />
    hBitmap = (HBITMAP)LoadImage(NULL, m_szThumb, IMAGE_BITMAP, 0, 0,<br />
		LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE | LR_LOADTRANSPARENT);<br />
<br />
    bitmapThumb.Detach();<br />
    bitmapThumb.Attach( hBitmap );<br />
    bitmapThumb.GetBitmap( &bmp );<br />
<br />
    rectThumb.top       = rectFill.bottom;<br />
    rectThumb.bottom    = rectThumb.top + bmp.bmHeight;<br />
    rectThumb.left      = roundf( ( rectClient.Width() - bmp.bmWidth ) / 2 );<br />
    rectThumb.right     = rectThumb.left + bmp.bmWidth;<br />
<br />
    brush.CreatePatternBrush( &bitmapThumb );<br />
    memDC.FillRect( &rectThumb, &brush );<br />
    brush.DeleteObject();<br />

Description of CreatePatternBrush says that Windows uses only the first 8 rows and columns of pixels from the bitmap you supplied. If you just need to display an image, why do not use bitmap-drawing functions, like BitBlt?

Hi again guys

This ADO is very frastrating as long as i find out one thing and i try to move on
there comes other problems.
This time i have a problem with _bstr_t

i need to give the value of string token to _bstr_t strName

i tryed _bstr_t= token;

but ofcorse i get incompatible error:: error C2440: 'initializing' : cannot convert from 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' to 'class _bstr

Any other way around
Appreciate

Token seems to be of type std::string, so try this:

<br />
_bstr_t s = token.c_str();<br />
<br />

Geez !!! You are on a forum here, it's not a chat Mad | :mad:

You posted this question 1 hour ago here[^]. You won't have more answers by flooding the forum !

And you won't have any answers if you don't provide VALUABLE informations !
The only thing I can say, is that you cannot use SDL with MFC. If you want to have a gui, take a look at CEGUI, it can work with SDL.

Does anyone have a link to a book I can get to help use SendInput effectively?

I asked question and everytime Im left with more questions.

Like how do I get the action coords from my window to the full screen so I can move the mouse to the correct location?

And many other ?'s.

I would like a book that explains how to use that, block input, mouse events, ect.

Anyone have a link?

1 line of code equals many bugs. So don't write any!
