ok, so here is what i have to say to you.

~~you idiot.~~ forget that Big Grin | :-D

you don't listen what we answered to you. still you are asking the same question exactly the same way (ya, one thing you know is copy/paste).

you definitely lost my support on that topic (even if i didn't really know how to help you), but abusing of our time and patience will never help you nowhere in your life. no one is paid over Codeproject to answer ausive people, so we don't owe you anything!!

if you want an answer, start asking it correctly. then, don't repeat yourself ; everybody here saw that you asked the same question thrice...

man, all you deserve is get flamed Mad | :mad:

i repeat myself once again. its seems that i'm not the only one here not to know what SDL is, but still you re ask your sh*t without much explainations.

google yourself, and come back here when you have a true question about a specific problem; not ask people to do a whole job for you Suspicious | :suss:

CString/strcpy error

I'm absolutly frustrated!
could a fresh set of eyes tell me why i'm getting this error:
(line 55) error C2664: 'strcpy' : cannot convert parameter 1 from 'char' to 'char *'

int main ()
{
CString sentence;
CString str("1");
CString str1("2.1");
CString num('\xDB');
char spc = ' ';
sentence = str + num + num + str1 + num + num;

for(int index = 0; index < (sentence.GetLength()); index++)
{
if(sentence[index] == num)
strcpy( (sentence[index]), spc); //line 55
}

printf ("%s \n",sentence);

return 0;
}

Thanks so much... Confused & Frustrated

The first parameter of strcpy function must be of pointer type, char *, but you supply sentence[index], which is a character of the string, not a pointer.

From the fragment, it seems that you need to replace a character with another one. For this task, try to use the Replace member function instead of your for loop:

<br />
sentence.Replace(num, spc);<br />

Dear Kitty!

U cannot copy a character to a string!!!
Instead make that space ' ' as " "(i.e, character as string constant)..
Then hope fully it should work.. Smile | :)

The above code is VERY VERY bad! Unfortunately, your compiler won't tell you exactly how bad it is, but I'll give you an alternative:

Replace the entire for-loop with the following:
sentence.Replace(spc, _T(' '));

A better solution would be to re-write the entire function to the following:

<br />
int main ()<br />
{<br />
  CString sentence;<br />
  sentence.Format("1  2.1  ");<br />
  printf("%s \n", (const char*)sentence);<br />
  return 0;<br />
}<br />

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.

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

Can someone please tell me if it's possible to capture a windows event(like when you receive a message with windows NET SEND) with a program. And if it is can you get like the IP from where the message was sent?

How to use Tokenize() wid CStrings in VC6

Cyber Friend1-Jun-06 4:55

Cyber Friend

1-Jun-06 4:55

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

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?
