Hi friends,
I have a export function in the DLL.
When this function is to be called from other application,
it has to show the form in which the DLL was built with.
Can anyone help out?
For example
//DLLMain.cpp file
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)
{
//what code should I write to show the form
}
//GraphDlg.cpp
class CGraphDlg : public CDialog
{
// Construction
public:
CGraphDlg(CWnd* pParent = NULL); // standard constructor
// Dialog Data
//{{AFX_DATA(CGraphDlg)
enum { IDD = IDD_GRAPH_DLG };
// NOTE: the ClassWizard will add data members here
//}}AFX_DATA
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CGraphDlg)
public:
virtual void OnFinalRelease();
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL
// Implementation
protected:
HICON m_hIcon;
// Generated message map functions
//{{AFX_MSG(CGraphDlg)
virtual BOOL OnInitDialog();
afx_msg void OnPaint();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

Show the dialog modal or modeless?
To do it modally, something like:
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)
{
CGraphDlg GraphDlg(NULL);
if (IDOK == GraphDlg.DoModal())
{
//user clicked "ok" - do something
}
}
You may want to pass a parent window pointer to the dll function so the dialog will have a parent.

As this function is called repeatedly in the calling program,
modalless dialog is needed.
<br />
CGraphDlg *pDialog;<br />
<br />
BOOL CMyDLLApp::InitInstance()<br />
{<br />
pGraphDlg=new CGraphDlg;<br />
pGraphDlg->Create(IDD_GRAPH_DLG,NULL);<br />
return TRUE;<br />
}<br />
<br />
extern "C" __declspec(dllexport) void MyDLLFunction(double* Data,int nData)<br />
{<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState());<br />
pDialog->ShowWindow(SW_SHOW);<br />
}<br />
But this code does not show the window.
I get Assertion Error.
The calling application is a C program.
So cannot pass the window pointer to the dll function.
Thanks for your answers.

The assertion is probably because the dialog has not been created.
Where do you call pDialog->Create()?

We use Microsoft Visual C++ 1.52. You can get it if you have an MSDN subscription.

the old age borland's do that also i believe, but i don't know much, as i never really played with borland C++...

Borland Turbo C++ 3.0 is free for download, try to google it. You'll also need DOS or Win95/98.

Dear All;
I write one multi threaded program in Visual C++.
It is responsible for reading raw data from hardware and analyse it.
I fine that my project hides from process view without any exception.
(I dont instruct the program to exit.)
Whould you please give me the reason of this problem.
Best Regards
Mahdi

Are you sure it still runs in the background?How do you term it as "hides" ?
And is it a console application?

Dear all
I Write a Multi threaded program which is responsible to read data from hardware and analyse it.
When I run the program all of threads work properly.
But after a while, one or some of threads die and no information is available from their state. ( I log live state of threads in a file. )
This abnormal behavior is computer dependent. On some computers I see such behavior but on another one, program works properly.
Do you know what is the reason of this problem.
Best Regards
Mahdi

if the thread is dying abnormally then it is posible that the OS is distorying the thread coz the thread might have gone into endless recurrsion.

no recurtion in progress.
Thanx for your advise.
|
|
|
|
|
So well does the thread disappears or does it end normally i.e the thread function returns normally.

I am not sure.
I should test.

yes you should, may put a breakpoint at the end of the function, or put some trace logs if you have them.

At the end of your thread loop, add a message box
<br />
your thread function<br />
{<br />
<br />
do<br />
{<br />
}while(xState=true);<br />
AfxMessageBox("I'm Done");<br />
<br />
}<br />
This is a simple way to test if it's getting out of the loop which also says that the thread is terminating.

Use a debugger and get a stack trace of what the thread is doing when it hangs.
