there are some syntax problem...
thanx

Hi,
see the following example whhich writes 25 chars to (FILE*)stream
/* Write 25 characters to stream */
char list[25] = "a...z"
numwritten = fwrite(list, sizeof( char ), 25, stream );
in your case it should be
fwrite(str,sizeof(char),strlen(str),fp);
For more info. plz refer to MSDN documentation of fwrite, wsprintf etc.
Enjoy !
Regards,
Vishal

Hi,
Try this:
FILE *fp1;
char output[1024];
sprintf(output,"the number of my phone is %.2x:%.2x:%.2x:%.2x:%.2x:%.2x\n",
(PCHAR)(Phone->Data)[0],(PCHAR)(Phone->Data)[1],
(PCHAR)(Phone->Data)[2],.....);
fputs(output,fp1);
Eli.

How can you do this for other browsers like Netscape or Opera? Can this be done for other browsers?

If it has been done can you tell where I can learn more about this or other good resource sites like the link above.
Thanks,

Hi,
I wrote the proxy app (WinSock) forwarding data from one socket to another. I listen for the client connection on the first socket, when the connection is established I create second socket and connect to the destination. Than I only forwarding data using these 2 sockets (client & destination).
My question: is it possible (after accept client connection) to bind client & destination sides without creating 2 sockets ? I mean, how to reroute connection only, without using my proxy to forward the data.
Thanks

No, it's not possible. Once a socket is connected, it cannot be reconnected without being disconnected first, and the reconnection can only be initiated by the client.

I'm trying to get Bumbleebee Software's lex and yacc generator up and running. I'm pretty experienced with lex and yacc, but only on unix systems. The problem is, if I use Bumblebee's ParserWizard, I get a good grammar and can compile, but the resulting application (I'm building into a windows console application) always crashes. I've tried "empty" grammars. I've also tried a grammar that can only produce a single non-terminal, i.e., it should be able to match an input of "binky", and nothing else. No matter what I try, the resulting application always crashes. I've tried reading from stdin and from a file, with no luck. I wish I could copy and paste some of the examples provided with bumblebee (like the calculator grammar), but it seems that most of them are the grammar without an accompanying lexer. I had hoped that there would be a complete example that I could compile in ParserGenerator and then compile in Visual C++ and have a working application (no matter how simple). But, apparently, no luck there.
I would be immensely grateful for any of the following:
1. Any simple grammar (and lexer if needed) that I can compile in Bumblebee and then MSVC and run the resulting console app without a crash.
2. Advice, tips, suggestions on what is needed to get a working Bumblebee generated grammar and lexer. I obviously don't know why my parsers and lexers are not working. Could it be because under unix, anything not parsed gets dumped to stdout, and this is not acceptable in windows? Is it something else that I have not done properly?
Thanks for any help you can offer!

I haven't used Bumblebee, but I have recompiled the linux flex and bison source and used them under Windows. I've never had the resulting scanners/parsers crash (except for my coding errors of course). I dunno if that helps much, but I can say it's not because of Windows.

I have just added a menu to an MFC dialog box and it comes up and works, but it does not look good under Windows XP. With the default XP color scheme, the background of the dialog and the menu bar should be tan, but behind the menu text the menu bar is white. Around the text the menu bar is tan. The drop down menus look normal with white backgrounds and tan borders. I'm sure this is a frequently encountered problem, but I have not been able to find anyone else's solution. Can someone give me a clue?

Why Can't you ask your teacher or teacher's assistant ?
it's vague, don't you have a real description for YOUR homework ? a set of criteria, instructions, course-ware, books, classes notes ?
don't want to sound rude, but your not giving us much ...

I'm trying to print an image to an area with certain dimensions in GDI+. First I construct a graphics object:
Graphics graphics(dc.m_hDC);
Then I load the image and print it:
graphics.DrawImage(pImage, rfDraw, rfPic.X, rfPic.Y, rfPic.Width, rfPic.Height, UnitPixel);
The rfPic rectangle is the source area to draw from, containing e.g. (0, 0, 1000, 800), the entire 1000 x 800 pixel image (I need to have the possibility to draw a portion of the image). The rfDraw rectangle is the destination area to draw to, containing e.g. (100, 100, 6100, 4900).
The printer has a 600 x 600 dpi resolution. Thus the printed image should be:
(6100 - 100) pixels / 600 dpi = 10 inches wide, and:
(4900 - 100) pixels / 600 dpi = 8 inches high.
However, the image is blown up to gigantic proportions. Can someone tell me why?
With smaller values in rfDraw, it works as expected when drawing to screen (which is 'just another device', but with 96 dpi). Also, similar code worked perfectly in GDI (without the +), using IPicture. I ported the code to GDI+, to be able to rotate and more.
I tried: using other unit values, like UnitDocument; setting the page scale and units to different values; checking the device resolution (indeed 600 dpi in both directions).
This is costing me a lot of paper and printer cartridges! Please help!
Thanks in advance!

Hi ..
Is there anyway.. to get the icon for the given file name? in c++?
I tried to convert following vb code to c++ using VS.Net. but I got errors
<br />
Function GetIconLocation(ByVal filename As String, ByVal index As Integer) As String<br />
Dim loc As String<br />
'Use this to get the small icon.<br />
Dim shinfo As SHFILEINFO<br />
shinfo = New SHFILEINFO<br />
Dim hImgSmall As IntPtr 'The handle to the system image list.<br />
<br />
hImgSmall = SHGetFileInfo("c:\" & filename, 0, shinfo, Marshal.SizeOf(shinfo), SHGFI_ICON Or SHGFI_LARGEICON)<br />
Dim hIcon As Icon<br />
'hIcon = hIcon.FromHandle(hImgSmall)<br />
hIcon = Icon.FromHandle(shinfo.hIcon)<br />
Dim bip As System.Drawing.Bitmap<br />
bip = hIcon.ToBitmap()<br />
loc = "c:\icon" & index.ToString & ".png"<br />
bip.Save(loc)<br />
loc = "<img src=""" & loc & """><br><font size=""-2"" face=""Times"">" & filename & "</font>"<br />
shinfo = Nothing<br />
Dim f As File<br />
f.Delete("c:\" & filename) ' delete the file<br />
GetIconLocation = loc
end Function
I tried to used
<br />
#using <mscorlib.dll><br />
#using <System.dll><br />
using namespace System;<br />
using namespace System::IntPtr;<br />
I dont' know how to use those namespace System classes from regular c++ in Visual Studio .Net.
Can anyone help me please?
Thank you.

ExtractIcon() comes to mind.

I am drawing a newbie blank here. Can someone show me how to read 20 bytes from the serial port using this code:
BOOL CSerialPort::ReadByte(BYTE &resp)
{
BYTE rx;
resp=0;
DWORD dwBytesTransferred=0;
if (ReadFile (hComm, &rx, 1, &dwBytesTransferred, 0))
{
if (dwBytesTransferred == 1)
{
resp=rx;
return true;
}
}
return false;
}
Thanks

I think you can solve this problem by the following code:
BYTE byte2Read[20];
for( int nRead=0; nRead<20;)
{
if( ReadByte( byte2Read[nRead] ) )
{
nRead++;
}
}

Can someone tell me why this isn't freeing up the memory like it suppose to?
Thanks
#include <afxwin.h>
#include <iostream.h>
class CDeeper : public CObject{
private:
CString *strTemp;
public:
CDeeper():strTemp(new CString){}
~CDeeper(){}
void setStr(CString setTemp){ *strTemp = setTemp; }
void Delete(){ delete strTemp; strTemp = NULL; }
};
class CTest : public CDeeper{
private:
int num;
CObList DeeperList;
CDeeper *pDeeper;
public:
CTest(){}
~CTest(){}
void setStr(int i){
num = i;
pDeeper = new CDeeper;
pDeeper->setStr("Hello");
DeeperList.AddTail(pDeeper);
}
void Delete(){
POSITION pos;
pos = DeeperList.GetHeadPosition();
while(pos){
pDeeper = (CTest *)DeeperList.GetNext(pos);
pDeeper->Delete();
delete pDeeper;
}
DeeperList.RemoveAll();
}
};
int main(){
POSITION pos;
CObList strList;
CTest *pTest;
int i;
for (i=0; i< 50000; i++){
pTest = new CTest;
pTest->setStr(i);
strList.AddTail(pTest);
}
pos = strList.GetHeadPosition();
while(pos){
pTest = (CTest *)strList.GetNext(pos);
pTest->Delete();
delete pTest;
}
strList.RemoveAll();
return 0;
}

Change CDeeper to:
class CDeeper : public CObject
{
private:
CString *strTemp;
public:
CDeeper(){}
~CDeeper(){}
void setStr(CString setTemp){ strTemp = new CString(setTemp); }
void Delete(){ delete strTemp; strTemp = NULL; }
};

I found out I can do
class CDeeper : public CObject{
private:
CString *strTemp;
public:
CDeeper():strTemp(new CString){}
~CDeeper(){ delete strTemp; strTemp = NULL; }
void setStr(CString setTemp){ *strTemp = setTemp; }
void Delete(){ }
};
Now I need to figure out why the three cases are different
|

|
|

One additional question on this. I notice when I call delete pTest it calls the destructor again and strTemp at that point is pointing to an unknown location with no value.
Anyway to prevent that?
