If you make your text boxes of a class you have derived from CEdit, then you can handle the WM_SETFOCUS message to know when a new edit box has gained focus after the user pressed tab.
Since you now know which edit got the focus, you can use GetWindowRect() (followed by ScreenToClient() on the window that holds the edit boxes), and compare this to your window's client rect - *after* the current scroll position has been used to offset the top and bottom of the window's rect. This will tell you if the new edit control is visible; if it is not, you can determine which way to scroll to bring it visible. This can be achieved by calling SetScrollPos() on the scroll bar.
I'm assuming you are comfortable with moving the edit controls to simulate being scrolled?

Thanks for ur Response,
I had tried LVN_ITEMCHANGED event. I write following code in MASSAGE MAP
as
BEGIN_MESSAGE_MAP(CSelectBusCategory, CPropertyPage) // Line 1
//{{AFX_MSG_MAP(CSelectBusCategory) // Line 2
LVN_ITEMCHANGED(IDC_PREVIEWLISTCTRL, OnSelectItemFromList) // Line 3
//}}AFX_MSG_MAP Line 4
END_MESSAGE_MAP() // Line 5
I also write definition for it as
void
CSelectBusCategory::OnSelectItemFromList(NMHDR* pNMHDR, LRESULT* pResult)
{
MessageBox(" Hiii");
}
When I compile this code, I got error in between
BEGIN_MESSAGE_MAP and END_MESSAGE_MAP(). These are
1)term does not evaluate to a function (Line 3)
2)syntax error : ';' (Line 5)
3)missing function header (old-style formal list?) (Line 5)
4)syntax error : missing ';' before '}' (Line 5)
5)syntax error : missing ';' before '}' (Line 5)
I could not find the reason why these errors are occure though the syntax are correct.I have solution then plz forward it.
Thanks in Advance

The proper way of handling a notification message is likewise
ON_NOTIFY(LVN_ITEMCHANGED, IDC_LISTID, OnListSelectionChanged)

Thanks Nibbu,
I can capture the select item event. Now I want to get the item text so for this I write following code in message function but returns me blank string. The code is as
CString strJPEGFileName = " ";
int nItem,nSubItem;
strJPEGFileName = mWebPagePrvListCtrl.GetItemText(nItem,nSubItem);
Is there any method to retrive text data of selected item.
Thanks in Advance

I am using VS2005 for VC++ application, and my solution contains many projects. I added project to source control using VS2005 "Add projects to source control" menu. It added all *.h & cpp files. But some other files having named "*.vcproj.vspscc" also got added to source control. Why? what is use of this file?
Also what all files from VS2005 project & solution to be added to VSS? I mean which files excluded from Adding to VSS, for a smooth working of group of people in a solution/project
Thanks

For Visual Studio 2005, you need to add these files to the source control (and of course, all your .cpp and .h files):
- .sln file: contains the information about the different projects that are in the solution. So, if someone adds or remove a project from the solution, it should be 'saved' for others also.
- .vcproj files: contains all the settings for each projects (you will have one vcproj file for each project). This contain for example the files that are in your project (so if someone adds a new file, it should be reflected), contains also the project properties (all the option that you can configure by clicking 'Project' -> 'Properties').
All the other files are not needed and will be automatically recreated.

Hi Pankaj!
Thanks for the help, but i don´t undertand C++ You know a more easy way to make this?
I explain: I have a old code in C++ and, now, i need use this code in a C# application, but the code is very big and i don´t have time to re-make everting.
So, i belive the more easy way is create a DLL with the old code, but not a COM object... or not

I start process which does CreateFilemapping as follows.
=====================================================================================
hMapFile = CreateFileMapping(INVALID_HANDLE_VALUE, // Current file handle.
&sa, // Default security.
PAGE_READWRITE, // Read/write permission.
0, // Max. object size.
1, // Size of hFile.
NONWTS_SERVICE_FILE_MAPOBJ); // Name of mapping object.
lpMapAddress = MapViewOfFile(hMapFile, // Handle to mapping object.
FILE_MAP_ALL_ACCESS, // Read/write permission
0, // Max. object size.
0, // Size of hFile.
0); // Map entire file.
.....
FlushViewOfFile(lpMapAddress, 0);
=====================================================================================
This process is running under session id = 1 and running under administrator user
without Administrative previlages.
From my other application(process) i call OpenFileMapping. This process is running under system context with session id = 0.
=====================================================================================
hMapFile = OpenFileMapping(
FILE_MAP_ALL_ACCESS, // Read permission.
FALSE, // Inherit handle
NONWTS_SERVICE_FILE_MAPOBJ); // Name of mapping object. //Non WTS Environment
=====================================================================================
Here the OpenFileMapping call fails. This same thing works fine if i have done the CreateFilemapping
from an application running under administrator user with Administrative previlages.
Can any one please help me in overcoming this problem.
Thanks in advance,
Praveen
