Hi ,
In my application I am using NOTIFYICONDATA structure to show tool tip. here the szTip can only contain 128 charecter. Is there any other way to use more charecters in tool tip?
Thanks in advance.

Not using the standard shell32 tooltip. I'm afraid that you will have to use a custom tooltip if you require additional features. There are a few articles here on codeproject which could be used.

By the way szTip can only contain 64 characters and not 128.

in the handler of your button in dialog A (the first dialog), just create the second dialog.
for modal dialog:
void MyDialogA::OnButton()
{
MyDialogB dlg;
dlg.DoModal();
}
for modeless dialog:
class MyDialogA
{
MyDialogB* m_pDialogB;
}
void MyDialogA::OnButton()
{
if ( m_pDialogB)
delete m_pDialogB;
m_pDialogB = new MyDialogB;
m_pDialogB->Create(IDD_DIALOG_B);
m_pDialog->ShowWindow(SW_SHOW);
}

I can't find any function for calculate the time between LBUTTONDOWN and LBUTTONUP,help me ~ 
|
|
|
|
|
Here is a generic example on how to get elapsed time:
CTime startTime;
CTime endTime;
CTimeSpan elapsedTime;
On LBUTTONDOWN: startTime = CTime::GetCurrentTime();
On LBUTTONUP: endTime = CTime::GetCurrentTime();
elapsedTime = endTime - startTime;
int timeout = elapsedTime.GetSeconds();

Also probably you can use GetCurrentMessage which contains a DWORD value which gives the time the message was posted. Note that you should only call this from event handlers. So call this from mouse up and mouse down.

You can use 'GetDoubleClickTime' to retreive double click time for your mouse.

m_datagrid.putref_DataSource(NULL);
m_datagrid.putref_DataSource((LPUNKNOWN) m_pRS );
//m_datagrid.Refresh();
I am using Visual Studio 2008 and somehow can't make my code to open the recordset. Any help is much appreciated.
Many thanks in Advance

Given the complete and utter lack of error checking, the root cause could be any of the statements before the record set open call. Check the status values to see where the error actually occurs, and then ask your questions...

my problem solved once I changed the char variable table to just EmployeeDetails but still want the ability to use select for more functionality.
Is it a little bit different in visual studio 2008.

I think it's the adCmdTable parameter - that says the command you're opening is a table. This page[^] documents the other options, while this page[^] suggests you want adCmdText if you want to use a SELECT statement as the command text.

I use a tab control in a dialog which is as a property setup window and put three dialogs into this tab control.Here is the problem,how can i destroy this three dialog and the mian dialog,return to the mian window.

If the dialog is modal, it will get destroyed when you click OK or Cancel.

Hi!
I have an application which sits in the system tray globally listening for a combination key press event (CTRL+ALT+T). Instead of opening the app by right clicking the app icon in the tray bar (clicking Open), I would like to open the app window upon CTRL+ALT+T. When that happens, sometimes (more often than not) the window loses focus/gets inactivated and I manually need to click it to regain focus.
What else besides the following lines of code can be done to force the app foreground, topmost, focused and active?
((CMyAppDlg*) AfxGetApp()->GetMainWnd())->ShowWindow(SW_SHOW);
((CMyAppDlg*) AfxGetApp()->GetMainWnd())->SetFocus();
((CMyAppDlg*) AfxGetApp()->GetMainWnd())->SetForegroundWindow();
Thx!

The behavior of the SetForegroundWindow Function[^] can be affected by SPI_GETFOREGROUNDLOCKTIMEOUT as described in the SystemParametersInfo Function[^]
See if this works for you:
HWND hWnd = GetForegroundWindow();
DWORD dwThread = GetCurrentThreadId();
DWORD dwProcessID = GetWindowThreadProcessId(hWnd,NULL);
if(hWnd > 0)
{
AttachThreadInput(dwProcessID,dwThread,TRUE);
(AfxGetApp()->GetMainWnd())->SetForegroundWindow();
AttachThreadInput(dwProcessID,dwThread,FALSE);
}

Hi all,
i have SDI type application,and split it in two columns.
for one column i m using a Treeview and for another one i m using a FormView.
The crash points to atlsimpstr.h line 107, trying to step through the debugger just tells me it is outside of the application, with ATLASSERT() inside CstringData in the method Release().
The debuger stops on the following "ATLASSERT()", obviously it expects nRefs to equal zero, and it is not so, but what does it refer to, I have no idea, or how do I find out either. This is inside "ATLSIMPSTR.H",
void Release() throw()
{
ATLASSERT( nRefs != 0 );
if( _AtlInterlockedDecrement( &nRefs ) <= 0 )
{
pStringMgr->Free( this );
}
}
My application's name is Test.EXE - here is the call stack dump at the point of the crash...

What are you doing in your CLeftView::ConnectNet function ? Show some code around the line 640, because it seems you are doing something wrong there. IT seems you are doing something wrong with a string assignement.
BTW, when you have such a crash, 99.999% of the time it means you did something wrong in your code. So, if you don't post any of the code around where the crash occurs, it's almost impossible for us to help you.

I asked for the CLeftView::ConnectNet method, not the HostInfo method. Could you post the correct method (and also indicate which line is the 640 line) ?
On the other hand, you have a flaw with your code: you suppose that UNICODE is always defined (because you always convert your input string to a multibyte characters string). If you later undefine UNICODE or wants to make a non-UNICODE build, your program will probably crash. Make sure you make the conversion only when unicode is enabled.

What is this HostInfo function ? I never saw that and I can't really find something usefull when googling for it. Do you have a link to the documentation ?
