Do you mean message box as in MessageBox(), or message box as in an IDC_STATIC text control?

Best wishes,

Hi
Can Context menu be system modal, so that if any tool tip appears,it should display behind my context menu not above it...

Thanks

1/ I doubt it.
2/ How long is this menu appearing for? Yikes...
3/ If there was an answer, how long before your competitor says "Can I make my tooltip system modal, so no menu appears on top of it?"

Point 2 is the main one - a menu is a temporary thing.

If you *really* want to do your thing, make a window with lines of text that disappears when you click on one. You don't have to actually use the menu functionality of windows. It will be more work, but tough. You want something way aways from the norm, you have to do it manually.

const char* str = "C:\\Documents and Settings\\Test\\TestData";
int i = sizeof(str);

i always 4. why?

Because str is a pointer and with sizeof(str), you're NOT finding the length of the string that str is pointing to.

If you need the length of the string, use strlen (or yet better use TCHAR and _tcslen)

Aside of what Rajesh R Subramanian suggested you can also try:

const char str[] = {"C:\\Documents and Settings\\Test\\TestData"};
int i = sizeof(str); //Note that this will also include the terminating NULL character

str is a char*, and a pointer has always a size of 4 bytes. sizeof returns the size of the pointer in this case, not the content. As Rajesh mentioned, you should use strlen instead.

You can try:
const char str[] = "C:\\Documents and Settings\\Test\\TestData";
int i = sizeof(str);

The difference is the name of array and the pointer.

Hi to All,

Could anyone please tell me, in which case program can be crush before main. And most importantly, how do we handle that?

thanks in advance

If you have global objects in your program their constructor runs before main gets executed and if these perform something ugly then your program will crash before hitting main. And you handle it by not doing anything that causes your program to crash. What do you mean by "How we handle that"?

We don't launch your program... Roll eyes | :rolleyes:

On the serious side: What program (or, at least kind of)? Could you please elaborate (and possibly post some code)? Could you debug it (the call stack window is usually pretty informative)?

Hello all
i made an application in which i had to display icons next to menu item and i did it successfully and it works fine in windows 2000, vista, 7 but in case of windows 2003 and Xp, there lies a problem as if in case any tool tip is displayed over my context menu, the menu item over which the tool tip lies that menu item`s icon (Only Icon And Not The Text)gets erased......

Can Anybody Suggest me where exactly the problem lies

Any help is highly appreciated

Note :: It happens Only In Case Of Win 2003 and Win. Xp

Did you display the popup menu the way it is suggested here[^]? I mean this:

SetForegroundWindow(hDlg);

   // Display the menu
   TrackPopupMenu(   hSubMenu,
                     TPM_RIGHTBUTTON,
                     pt.x,
                     pt.y,
                     0,
                     hDlg,
                     NULL);

   PostMessage(hDlg, WM_NULL, 0, 0);

I know this seems unrelated to the drawing part but who knows...

Exe is getting crashed when i enter wrong password/username

Hi all,
I have migrated my application(vs-2003 developed) into vs-2008 to be worked on vista machine.I got the .exe and working successfully when i enter a valid username and valid password but fails when i enter a wrong password/username......I am using SYBASE for my aplication,so it comunicates with some SYBASE dlls to get the access.
the code looks like below
(I am providing login details from other dialog)

int DBInterface::LoginSequence (BOOL bFirstLogin)
{
CString user_name;
char dbver[16];
CString srvrname, dbname;
char uname[33];
char upwd[33];

UINT msg;

if (bFirstLogin)
{
dbinit ();
dbsetlogintime (8);
dbmsghandle ((MHANDLEFUNC) msghandle);
dberrhandle ((EHANDLEFUNC) errhandle);
}

int rv = 0;

while (Ops.m_bAutologin && bFirstLogin)
{
if (CSD_DdeReqUserName (uname) == 0)
break;

if (CSD_DdeReqUserPassword (upwd) == 0)
break;

srvrname = App.GetProfileString (INI_SEC, _T("DBServer"), "");
if (srvrname.IsEmpty ())
break;

dbname = App.GetProfileString (INI_SEC, _T("DBDatabase"), "");
if (dbname.IsEmpty ())
break;

strcpy (_loginfo.dbid, uname);
strcpy (_loginfo.dbpwd, upwd);
strcpy (_loginfo.dbsrv, srvrname);
strcpy (_loginfo.dbdb, dbname);

_dbproc = dbConnect (&_loginfo, "Phoenix");

if (_dbproc == NULL)
break;

rv = 1;

TRACE0("Phoenix: successfully logged in using LOGPARMS from anotherapp...\n");

break;
}

CLoginDlg dlg;

while (rv == 0)
{
if (dlg.DoModal() != IDOK)
{
PostQuitMessage(0);
return 0;
}
else {
lstrcpyn(_loginfo.dbpwd, dlg.m_csPassword, 31);
lstrcpyn(_loginfo.dbid, dlg.m_csUser, 31);
lstrcpyn(_loginfo.dbsrv, dlg.m_csServer, 31);
lstrcpyn(_loginfo.dbdb, dlg.m_csDatabase, 31);
}
_dbproc = dbConnect (&_loginfo, _T("Phoenix") );

if (_dbproc != NULL)
break;

msg = (::GetKeyState (VK_CAPITAL) & 0x0001) ?DS_ERR_LOGINFAILEDCAPS : IDS_ERR_LOGINFAILED;

if (AfxMessageBox (msg, MB_OKCANCEL | MB_ICONHAND) == IDCANCEL)
{
PostQuitMessage(0);
return 0;
}
}

In the abobe code from dbconnect()(bold code) it is calling some SYBASE dll and it is not getting the return value when i enter wrong password/username.......
Is there any problem with the dll or anyting else?????
Since i have migrated the code i am thinking that the dll is not compatiable,but this is just an assumption....!
So can anybody help me to solve this issue......

Thaks in advance.
