Did anyone use 3rd argument in random_shuffle.
As I start the project for the first time it always sort the array the same way, I wonder if 3rd argument will help

Yes it would allow you to provide your own randomising function possibly with something a little more random than the rand() function.
You say it always sorts the same way, did you forget to call srand() first? Faliure to do this would cause the same random numbers to be be produced. A common method is to call srand(time(NULL)) though it's been a while since I used it.

no I didnt call srand(time(0)) before random_shuffle().
I thought it was useful only before rand() function call?
Does random_shuffle() use rand() function for generation? And it does not call srand() initialization in it?
If somebody knows how to paste custom function into 3rd argument?

I'm guessing that it would use rand() given that it's already in the libraries and that your output is always the same. It wouldn't make sense if srand() was called on your behalf since you would never know what is being passed to it.
Did calling srand() work for you? you didn't say.
|
|
|
|
|
yes after calling srand() before random_shuffle() it randomize sequency differently with every run

hai iam beginnar in vc++ , I want to know the difference between Runtime and link time.
"the client code can load the DLL and link to the functions at  run time (instead of at compile time and link time). That way, only one copy of a given library resides on a disk at any particular time. All the clients of the DLL simply share that one copy of the library, freeing up disk space and memory resources for other things."
Iam Quoating this from "Inside ATLCOM"

This is also called explicit linking.

Both terms can be Googled for.

basically :
- compile-time (or compilation) is when the compiler take each .cpp (or .c in C) files to create the relative .obj.
- link-time is when the linker links every object files of the compilation to generate the project output.
- run-time is when you execute the program...

Run time is the time at which you run the program and compile time is the time at which you comile the program (yes, really  ).
So what does that mean ? It simply means that (in your case) the dll functions are loaded when you run your program. So during compilation and linking, these particular functions are not 'merged' with your program.

Krishnatv quoted: That way, only one copy of a given library resides on a disk at any particular time. All the clients of the DLL simply share that one copy of the library, freeing up disk space and memory resources for other things.
That assertion is not completely correct - some applications routinely place "private copies" of DLLs in their own runtime/installation directories. You may have heard the term "DLL Hell" in the past few years...
How DLL's are searched for (search order) can also screw around with applications if you are not careful or have odd things in your PATH.

when your program is to be eceuted first it is compiled, then it is linked. in the linking process all the necessary header files and libraries and attached to your object file(i.e. the file got after compiling). this is called link time. after linking u get .exe of your source code.
now when this file is run for final output, it is called runtime.
i hope u r clear by now.
best of luck

I have used CHelperLAyout Class to solve my positioning and resizing problem but I have a new problem that is: the ComboBox controls don't change their size . What to do
I lern my self
|
|
|
|
|
height of ComboBox is fixed for same fonts.
when u change height of combo-box, the height includes dropdown part.
in most cases, u should use a large number for its height, i.e. 200.

I increase the height, some thing don't change.
How can I do so to have the same height for all control on my formview using this class CLayoutHelp.

I only get a 8.3 format filename through following code, and I want to get a long filename, how?
HINSTANCE hInst = AfxGetInstanceHandle();
if(FAILED(!hInst)) return E_FAIL;
CString strDllFileName;
DWORD Status = GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName, MAX_PATH);
TRACE(strDllFileName);
by debugging, I find that the value of strDllFileName is F:\hu\DD\DETAIL~1\Debug\DETAIL~1.DLL, and the corresponding longname is F:\hu\DD\DetailDesign\Debug\DetailDesign.dll
Note:
I am programming in VC++ 6.0, my Operating System is Windows XP, the Disk F: ,where the .dll file is located, is NTFS format.
Thank you very much!!!

Have you considered GetLongPathName()?

Hello
you can try this function which transform the path you get from GetModuleFileName...
<br />
typedef DWORD (__stdcall *GETLONGPATHNAME)(LPCTSTR, LPTSTR, DWORD);<br />
<br />
DWORD MyGetLongPathNameEx (CString& sPath)<br />
{<br />
DWORD dwRet = 0;<br />
<br />
HINSTANCE hdl = ::LoadLibrary ("KERNEL32.DLL");<br />
if (hdl == NULL)<br />
return dwRet;<br />
<br />
GETLONGPATHNAME pfnGetLongPathName = (GETLONGPATHNAME) GetProcAddress (hdl, "GetLongPathNameA");<br />
if (pfnGetLongPathName == NULL) {<br />
::FreeLibrary (hdl);<br />
return dwRet;<br />
}<br />
<br />
dwRet = (pfnGetLongPathName) (sPath, sPath.GetBuffer (_MAX_PATH), _MAX_PATH);<br />
sPath.ReleaseBuffer ();<br />
<br />
::FreeLibrary (hdl);<br />
return dwRet;<br />
}<br />
<br />
<br />
CString strDllFileName;<br />
DWORD Status = ::GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName.GetBuffer (_MAX_PATH), _MAX_PATH);<br />
strDllFileName.ReleaseBuffer ();<br />
DWORD dwRet = ::MyGetLongPathNameEx (strDllFileName);<br />
TRACE(strDllFileName);<br />

use GetLongPathName after u have got the short file name.
I would like to comment that the statement
DWORD Status = GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName, MAX_PATH); is wrong.
u should never cast CString like (LPTSTR)(LPCTSTR)strDllFileName. U may have unexpected results because of this. Use as follows
DWORD Status = GetModuleFileName (hInst, strDllFileName.GetBuffer( MAX_PATH ), MAX_PATH);
strDllFileName.ReleaseBuffer( -1 );

Let me try to actually answer the subject of ou post...
That function dates back to 16-bit Windows, and my guess is that since only FAT-style 8.3 filenames were supported, Win32 inherited that behavior.
Also, note that the GetModuleFileName(...) function is one of the few that is capable of returning filepaths longer than MAX_PATH, so do not assume that MAX_PATH is always going to be long enough...
Peace!

Hi!
Does somebody know, what I have to do, when there is a .rtf-File which should be converted to a WinHelp-File? I don't have a .cnt but a .hpj-File.
Thanks a lot, Hanno
