Hi,
The std::unique_ptr[^] is unique meaning non-assignable and non-copyable so you will need to use move semantics to pass it around or give up ownership with unique_ptr::release()[^].
func(u_ptr.release(), 10);
Best Wishes,
-David Delaune

In both cases, if you want sample code then you should go and search for it, There are many articles that can be found here on CodeProject, or by Google, that show how to manage images.

I already told you where to look, please make an effort to do your own research.

No. We can't. You haven't described your problem well enough for us to properly search for it. Only you know what you need exactly, so you do the search!
Besides, even if you took the time to precisely describe what you want, it would take as at least as much time to search for those links as it would take you - so why should we? Please learn to use the search function, here, on google, or on any other site that you might consider useful (e. g. MSDN). That will save everyone a lot of time - including yourself!

Hi all,
While debugging the following code,
inline LONG CRegKey::QueryValue(LPTSTR szValue, LPCTSTR lpszValueName, DWORD* pdwCount)
{
ATLASSERT(pdwCount != NULL);
DWORD dwType = NULL;
LONG lRes = RegQueryValueEx(m_hKey, (LPTSTR)lpszValueName, NULL, &dwType,
(LPBYTE)szValue, pdwCount);
ATLASSERT((lRes!=ERROR_SUCCESS) || (dwType == REG_SZ) ||
(dwType == REG_MULTI_SZ) || (dwType == REG_EXPAND_SZ));
return lRes;
}
Here the value for (LPTSTR)lpszValueName is 'SQLPath' and the value which returns for 'szValue' in RegQueryValueEx method is “c:\Program Files (x86)\Microsoft SQL Server\100\Tools\” which should be “c:\Program Files\Microsoft SQL Server\100\Tools\”
We have noted that the data value for SQLPath in RegistryKey "SOFTWARE\Microsoft\Microsoft SQL Server\100\Tools\ClientSetup" is “c:\Program Files\Microsoft SQL Server\100\Tools\”
Could anybody please tell why RegQueryValueEx method is returning a wrong value “c:\Program Files (x86)\Microsoft SQL Server\100\Tools\” which should be “c:\Program Files\Microsoft SQL Server\100\Tools\”
Thanks in advance

It may be that you are running a 32 bit application, in which case it will use Program Files (x86), which is where the 32-bit versions are located.
|
|
|
|
|
Thanks a lot!!
|
|
|
|
|
When a 32 bit application accesses the path starting with SOFTWARE under the key HKEY_LOCAL_MACHINE on a 64 bit OS, there is a Wow6432Node added automatically after the SOFTWARE. So the path you really accessed was
"SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server\100\Tools\ClientSetup"
instead of the one you expected.
Depening on what you want to use the information for, you may need to compile your app as x64.
The good thing about pessimism is, that you are always either right or pleasently surprised.

Hi,
I'm trying to read a BMP image, the code is as follows. If i'm using a value 820 as BMP_HEADER_SIZE, my program works fine. I tried calculating the BMP_HEADER_SIZE value by summing the size of structure tagBITMAPFILEHEADER and tagBITMAPINFOHEADER (from BMP header file) but the program is not working. How can i solve this?
Class BlockinessProc.
# define BMP_HEADER_SIZE 820
void ReadImage(const char* filename);
char m_info[BMP_HEADER_SIZE];
unsignedchar** m_memblock;
void Blockinessproc::ReadImage(const char* filename)// Reading a BMP Image
{
streampos size;
ifstream inFile;
inFile.open(filename, ios::in|ios::binary);
if (inFile.is_open())
{
inFile.seekg (0, ios::beg);
long nHeaderSize = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER);
inFile.read ((char*)m_info, nHeaderSize);
width = *(int*)&m_info[18]; //Getting Image width from Header
height = *(int*)&m_info[22];// Getting Image height from Header
long pos = inFile.tellg();
m_memblock = new uchar* [width];
m_memblock_out = new uchar* [width];
for (int i = 0; i < height; i++) // create new array size: height of image.
{
m_memblock[i] = new uchar [width*3];
m_memblock_out[i] = new uchar [width*3];
}
int size_s = inFile.gcount();
inFile.seekg (pos);
for(int i=0; i<height; i++)="" read="" row="" into="" each="" array="" entry.
="" {
="" infile.read="" (reinterpret_cast<char*="">(m_memblock[i]), width*3);
}
inFile.close();
}
}
Thanks in Advance

Please edit your question and format you code by placing <pre> tags around it, so it is readable like:
streampos size;
ifstream inFile;
inFile.open(filename, ios::in|ios::binary);
Also, and most important, please explain what "the program is not working" means.
|
|
|
|
|
I have the same question, what is meaning of the program is not working.
Be crashing or something else.
|
|
|
|
|
You know, the BITMAPFILEHEADER may be followed either by a BITMAPINFOHEADER or by a BITMAPV4HEADER or by a BITMAPV5HEADER structure, see the documentation[^].
Veni, vidi, vici.

Please do not dump a huge block of code like this and expect people to debug it for you. Edit your question and remove all the lines that are not relevant to your problem. Place <pre> tags around the remaining code so it is readable, and show clearly which is the line in error.

|
|
|

Edit already Can U help Me Please....
|
|
|
|

Well, you did not remove all the code that is not relevant. However your second parameter on the connect call is defined as a struct sockaddr_in* but according to the documentation[^] it should be a struct sockaddr*.
|
|
|
|
|
Give i do this ==> Yes or not
if (connect(sockfd,(struct sockaddr *)&serv_addr,sizeof(serv_addr)) < 0) {
close(sockfd);
return(0);
}
|
|
|
|
|
Yes you can do that but you need to check that both structures are exactly the same in both content and size.
