Hello,
Maybe a std::string[^] or a std::stringstream[^] can be of some help..
If not, you have to use strings of TCHARs (see the tchar.h header). You also have to use a lot of C string functions.

Can you please elaborate more on this Bob?

Hello,
See the following code examples and see the difference between the CRT and the STL:
double dValue = 99.9;
std::stringstream sstr;
sstr << _T("This is some string with a double: ") << dValue << std::endl;
double dValue = 99.9;
TCHAR szBuf[1024] = {0};
_sntprintf(szBuf, 1023, _T("This is some string with a double: %f", dValue);
Some differences of the STL compared to the CRT are:
<list> You don't have to use buffer magic, the STL does it for you
You don't have to use range checking as much as with the CRT
The syntax looks more clean
 I remember now a nice CString replacement written by another CPian: CStdString[^]. You can use this class instead of the MFC CString without too much hassle.

Note: The define UNICODE has no effect on standared streams or strings. Therefore, the _T() does not realy apply unless you do one of the following:
---------------------------------------------
#ifdef UNICODE
std::wstringstream sstr;sstr << _T("This is some string with a double: ") << dValue << std::endl;
#else
std::stringstream sstr;sstr << _T("This is some string with a double: ") << dValue << std::endl;
#endif
---------------------------------------------
#ifdef UNICODE
std::wstringstream sstr;sstr << L"This is some string with a double: " << dValue << std::endl;
#else
std::stringstream sstr;sstr << "This is some string with a double: " << dValue << std::endl;
#endif
---------------------------------------------
std::basic_stringstream<TCHAR> sstr;sstr << _T("This is some string with a double: ") << dValue << std::endl;
---------------------------------------------

Hi
I have a program with MFC that include Two panes
left pane for TreView and Right pane for List View
and there is icon at toolbar show me Dialog
after inserting data at dialog the TreeView must do refresh for data that came from database
how could i exchange data between the TreeView and Dialog(not FormView)??
MFC programmer

|

if u r reading the database in treeview, U can send a user defined message to the treeview from dialog to refresh it by reading the updated database .

U can send a user defined message to the treeview from dialog
this code i wrote at LeftView.cpp(TreeView):
#define WM_REFRESHTREE (WM_APP)<br />
<br />
BEGIN_MESSAGE_MAP(CLeftView, CTreeView)<br />
ON_MESSAGE(WM_REFRESHTREE,AddData) <br />
END_MESSAGE_MAP()<br />
<br />
<br />
<br />
void CLeftView::AddData()<br />
{<br />
if(db.IsOpen()==false)<br />
db.Open();<br />
db.MoveFirst();<br />
GetTreeCtrl().DeleteAllItems();<br />
while(db.IsEOF()==false)<br />
{<br />
GetTreeCtrl().InsertItem(db.m_name);<br />
db.MoveNext();<br />
}<br />
}
from MyDlg.cpp (Dialog):
void CMyDlg::OnButton1() <br />
{<br />
CLeftView *obj;<br />
obj->PostMessage(WM_REFRESHTREE);<br />
}

I doubt the function declaration. A crash is expected when you send a message to a window that doesnt handle it. See below MSDN quote:
User Defined Windows Messages
User-defined messages may be included in a message map by using the ON_MESSAGE macro. This macro accepts a message number and a member function of the form:
// inside the class declaration
afx_msg LRESULT OnMyMessage(WPARAM wParam, LPARAM lParam);
For example:
#define WM_MYMESSAGE (WM_USER + 100)
BEGIN_MESSAGE_MAP(CMyWnd, CMyParentWndClass)
ON_MESSAGE(WM_MYMESSAGE, OnMyMessage)
END_MESSAGE_MAP()
WPARAM and LPARAM are required in the function declaration even though you dont use it.

Huh? A crash should never be expected, especially if a window receives a message that it does not handle. If a window receives a message that it does not handle, DefWindowProc() or DefDlgProc() just sends it on.

Not recommended. While older books and tutorials used WM_USER, these symbols caused problems by conflicting with messages that Microsoft was using. Use WM_APP instead.

I presume some method in the tree view class is in charge of displaying the dialog. Correct? If so, then you'll want something like:
void CMyTreeView::OnButtonClick()
{
CMyDialog dlg;
if (dlg.DoModal() == IDOK)
{
}
}Make sense?

I guess I'll have to go back and change all of my working code to longer work. I've done it so many times, it might take a while, but if you say there is no solution, well...

I thought the code snippet I provided was sufficient. As it is apparently not, please show the code you are using when the button is clicked to display the dialog box.

All I asked for was one function. How big can that be?
Why did you save the file as Roshal Archive (RAR) instead of something more common (e.g., ZIP), or uncompressed since it is just a text file?

I have a serious problem. I hv a VC application which has a feature to write to a DVD, which we have implemented as a DLL which inturn uses another DLL(which has been bought).
from my aplication i open a dialog(which is part of the dll) which takes in the parameters required for burning.
Initialy i click on the build button of the dialog.It shows the progress bar,but as the progressbar is on if i cancel the dialog then the application crashes.
once the progress is completed and then i cancel then the appllication does not crash
if anybody can think for a solution on this then plz let me know
