i have declared a variable TCHAR TBuf[ 512 ] in public section of a class. How i can initialize this variable .
if i declare the variable in a local function i initialize it as TCHAR TBuf[512] = {'\0'} , in this method entire buffer (512) bytes is initialized. How to perform this kind of initialation on a class variable.
Thanks & Regards

On the constructor of the class
MyClass::MyClass ()
{
}

void MyFunc()
{
TCHAR TBuf[ 512 ] = { '\0' } ;//this method initializes the array index 0 to 511 with null
}
//in the case of a class varibale i use the following method, is there any simple step to do the same ?
class MyClass
{
public :
TCHAR TBuf[ 512 ] ;
MyClass()
{
//
int i = 512 ;
while( i > 0 )
{
TBuf[ --i ] = '\0' ;
};
}
}
Thanks & Regards

better use ZeroMemory Api! or memcpy!

Au contraire!
Why should one not use a C++ function instead of something more complicated and proprietary?

As DavidCrow mentioned, you can use memset().
Also, I would recommend NOT using hardcoded values like 512...
use the sizeof operator.
class MyClass
{
public :
TCHAR TBuf[ 512 ] ;
MyClass()
{
memset(TBuf, 0, sizeof(TBuf));
}
};

I am using CreateDestop() API to create a new Desktop and SwitchDesktop() API to switch to new desktop.It works fine without any errors.
But the problem is that I am not able to open any process in new Desktop. I am not even able to open the Taskmanager in new desktop. What I get is only blank desktop there.
I am using following code to Create and Switch to new Desktop.
If you know what is the probelm please inform me.
hNewDesktop = CreateDesktop(L"NewDesktopName", NULL, NULL, 0, GENERIC_ALL, NULL);
SetThreadDesktop(hNewDesktop);
SwitchDesktop(hNewDesktop);
OpenProc(_T("userinit.exe"));
OpenProc(_T("Explorer.exe"));
Thnx in advance.

Hello
I have been trying to implement the sample at the link http://www.codeproject.com/useritems/GetNtProcessInfo.asp[^]
Its mentioned in the article to add the files "NTProcessInfo.h", "NTProcessInfo.cpp" to my project and exclude them while building the project.
I have followed the instructions to add the files and exclude them while building the project. I did a #include "NTProcessInfo.h" at the top of my file MsiInfo.cpp.
However, I get the following linking errors mentioned below:
MsiInfo.obj : error LNK2001: unresolved external symbol "void __cdecl sm_FreeNTDLLFunctions(struct HINSTANCE__ *)" (?sm_FreeNTDLLFunctions@@YAXPAUHINSTANCE__@@@Z)
MsiInfo.obj : error LNK2001: unresolved external symbol "int __cdecl sm_GetNtProcessInfo(unsigned long,struct _smPROCESSINFO *)" (?sm_GetNtProcessInfo@@YAHKPAU_smPROCESSINFO@@@Z)
MsiInfo.obj : error LNK2001: unresolved external symbol "struct HINSTANCE__ * __cdecl sm_LoadNTDLLFunctions(void)" (?sm_LoadNTDLLFunctions@@YAPAUHINSTANCE__@@XZ)
Can somebody please tell me what is the reason for this?
Thanx.

It seems you need to import lib file or files to your project.

Hi,
I have a splitter window project with 2 colums.
My left pane base class is "CFormView" and right pane is "CScrollView".
How to share a common Vertical scroll bar for both panes ?
Thanks in advance.

I dont know how to share it, but you can always sincronize both of them when one is moved.
In the OnScroll () or by OnScrollBy () you can make something like:
int nVertPos = pDoc->m_csbMyScrollBar1->GetScrollPos (SB_VERT);
pDoc->m_csbMyScrollBar2->SetScrollPos (SB_VERT, nVertPos, bRedraw);
pDoc->UpdateAllWindos (NULL);
I'm supposing a CScrollBar* for every one of them in the document, to have easier access to both with independance of which view is the active.
Or something like this.
Hope it helps
Greetings.

One method is that when you receive the VScroll messages for one view, send them to the other also, provided the range and thumb size are same for both.

Hello all;
I'm currently working on encryption algorithm for small embedded systems.....I had selected a combination of RSA and Blowfish.....where RSA is used for the session key encryption...
Could any body suggest a method of transferring the public keys to the recipients with authentication without using the CA certification or PKI....as its dealing with embedded systems and having a third party to monitor the public key transfer is a major area of concern..
Any help in this regard will be greatly appreciated..
Thanking you'll in advance..
