Hy
I am a newby in encoding/decoding. I am writting a function in C++ that would decode an URL encoded string. It works fine if the string does not contain unicode characters. Whenever I find a "%" I convert the fallowing two digit number from hex to int and add to the returning string the character corespounding to the int. When the URL contains unicode characters there is a "u" after the "%" fallowed by a 4 digit hex. I managed to convert the for digit hex to int. But I am not able to get the character corespounding to this int.
Could anyone give some advice ?
10x in advance

Try using the following code for encoding and decoding the URL
CString URLDecode(const CString& inStr)
{
CString res;
for (int x = 0; x < inStr.GetLength(); x++)
{
if (inStr.GetAt(x) == _T('%') && x + 2 < inStr.GetLength() && IsHexDigit(inStr.GetAt(x+1)) && IsHexDigit(inStr.GetAt(x+2)))
{
TCHAR hexstr[3];
_tcsncpy(hexstr, inStr.Mid(x+1, 2), 2);
hexstr[2] = _T('\0');
x += 2;
res.AppendChar((TCHAR)_tcstoul(hexstr, NULL, 16));
}
else
{
res.AppendChar(inStr.GetAt(x));
}
}
return res;
}
CString URLEncode(const CString& sInT)
{
CStringA sIn(sInT);
LPCSTR pInBuf = sIn;
CString sOut;
LPTSTR pOutBuf = sOut.GetBuffer(sIn.GetLength() * 3);
if(pOutBuf)
{
while (*pInBuf)
{
if (_ismbcalnum((BYTE)*pInBuf))
*pOutBuf++ = (BYTE)*pInBuf;
else
{
*pOutBuf++ = _T('%');
*pOutBuf++ = toHex((BYTE)*pInBuf >> 4);
*pOutBuf++ = toHex((BYTE)*pInBuf % 16);
}
pInBuf++;
}
*pOutBuf = _T('\0');
sOut.ReleaseBuffer();
}
return sOut;
}

Are you looking for something like UrlCanonicalize(), or maybe the UrlEescape()/UrlUnescape() pair?

please set a nickname in your profile so that everybody can identify you.
BTW, are you using MFC ? is so, you can use the CWnd::SetTimer() function for this purpose

There are more than one anonymous things around.
This one has only 2 posts.
It seems there is a loophole in the register user dialog of codeproject.
Failure is not an option - it's built right in.

If it's a worker thread you could create it once (as thread creation in Win32 is relatively expensive) and have it Sleep between runs. For example:
void __cdecl ThreadFunc(void *)
{
for( ; ; )
{
DWORD WaitRes = WaitForSingleObject(g_hKillThreadEvent, 4000);
if (WaitRes==WAIT_OBJECT_0)
{
return;
}
}
}

1st of all sorry for posting this entire program hope its not a large 1. This program has been tested in gcc,msvc,tc to give the same result. My question is how does it work
#include <stdio.h>
void Call_Aswathy()
{
printf("Yes Girish........\n\n");
}
int Call_Girish(int w_argc)
{
printf("Aswathy do u hear me...\n\n");
unsigned int *p = (unsigned int *)&w_argc;
*p = *(p-1);
*(p-1) = (unsigned int) &Call_Aswathy;
return w_argc;
}
int main(int argc,char **argv)
{
unsigned int *p = (unsigned int *) &argc;
*p = *(p-1);
*(p-1) = (unsigned int) &Call_Girish;
return 0;
}
if some1 has posted a this question or similar question before plz post the exact link or mail the link
thx in advance

How about adding breakpoints inside the functions, and see what the callstack looks like when they get called
|
|
|
|

This is probably one of the wurst ways to call a function on exit of another function.
To see what happens one should know a little/lot about the way c/c++ works and look at the assembly code.
Simply said: the programmer (prob a hacker who deserves to be shot  ) is overwriting the return address of the function. So when the function exit it returns to the newly linked function instead.
codito ergo sum

Use SHGetFileInfo.
SHFILEINFO shfi = { 0 };
SHGetFileInfo( _T( "your_bmp_file_name.bmp" ),
FILE_ATTRIBUTE_NORMAL,
&shfi, sizeof(shfi),
SHGFI_ICON|SHGFI_USEFILEATTRIBUTES );This code retrieves icon associated with bmp file type.

Thanks !
but how can I add the icon in the listview. Look at the source code.
LvItem.iItem=0;
LvItem.iSubItem=0;
HIMAGELIST llistaImatgesG=ImageList_Create(GetSystemMetrics(SM_CXICON),GetSystemMetrics(SM_CYICON),ILC_COLOR32|ILC_MASK,1,1);
HICON hIcona=LoadIcon(hInst,MAKEINTRESOURCE(IDI_QUESTION));
<code>
SHFILEINFO shfi = { 0 };
SHGetFileInfo( _T( "quest.bmp" ),FILE_ATTRIBUTE_NORMAL,&shfi, sizeof(shfi),SHGFI_ICON|SHGFI_USEFILEATTRIBUTES );
</code>

SHFILEINFO has an hIcon member that holds the icon of the corresponding file type. You can use that icon.
