Using STL with SmartHeap

I've a problem using std::string in a VC6 application. As I've to connect to Oracle, so I use OCCI (Oracle C++ Call Interface), and link with OCCI LIB's. However, their functions are using std::string as parameters, but my most of my application is using LPCTSTR stuff to pass parameters.

When I add the lines below, without do any other coding. It throws SmartHeap memory exception

BOOL OCCI_Database::Open(LPCTSTR lpszServiceName, LPCTSTR lpszUserID,
LPCTSTR lpszPasswd)
{
.....
string userName = W2A(lpszUserID);
string password = W2A(lpszPasswd);
string connectString = W2A(lpszServiceName);
.....
}

I think the implementation of STL has itself heap allocator, and smartheap is a different one? But I don't know how to solve the issue.

Programs running in windows are resident unless you close it.

I think the term resident came from DOS operating system where we can execute one program at a time.

Hooking is a stuff related to it. check codeproject or MSDN for articles.

Under Windows XP, an application that is 'resident' is called a service. This[^] is a very good introductory article.

GetSafeHwnd().
Don't get what you mean by your second sentence.
GetClientRect()/GetWindowRect().

It would be great if you organized your request in sentences.
What you wrote is really hard to understand.

But well...

To get a handle of a Dialog, you can use the method GetSafeHWnd(), or the member m_hWnd.
If you can't use that, you can try looking for your window through FindWindow()

What's the error you are getting? is it a compilation error?

CFileDialog

Hi all,

I need to open ascii files in a project and i do that like this;

CString str;
CFileDialog fd(TRUE, NULL, str, OFN_FILEMUSTEXIST | OFN_HIDEREADONLY);

if (fd.DoModal() == IDOK)
{
str = fd.GetPathName();
UpdateData(false);
[...]
}
I'd like to know:
1) how to modify the dialog caption (default is "Open File")
2) what's the meaning of UpdateData(False)
3) what should i do to save a file instead of loading it.

Thanx in advance,
Desmo16.

Chaning the text of the file dialog is simple.
try this code

CFileDialog dlg(true);<br />
dlg.m_pOFN->lpstrTitle = "Save as new title";<br />
dlg.DoModal();

You can use also GetOpenFileName and for save GetSaveFileName
see MSDN for UpdateData
In MSDN:

<code>
"CWnd::UpdateData
This method initializes data in a dialog box, or retrieves and validates dialog data."

How to get a Handle Type

Kharfax4-Jul-06 3:32

4-Jul-06 3:32

Hi people

I belive I have seen a WIN32 funtion that you can use to know the type of a Handle.
I need to know if a handle references a file, a file map or another thing.

Does anybody knows how I can do that? I tried at msdn.com but I can't find anything

Thanks in advance Big Grin | :-D

Sometimes GetTokenInformation helps you. I haven't tried it.
