CMyDialog* pDialog;
void CMyWnd::OnSomeAction()
{
//pDialog initialized to NULL in the constructor of CMyWnd class
pDialog = new CMyDialog();
//Check if new succeeded and we got a valid pointer to a dialog object
if(pDialog != NULL)
{
BOOL ret = pDialog->Create(IDD_MYDIALOG,this);
if(!ret) //Create failed.
AfxMessageBox("Error creating Dialog");
pDialog->ShowWindow(SW_SHOW);
}
else
AfxMessageBox("Error Creating Dialog Object");
}
//copy from MSDN
Use the WS_VISIBLE style in the dialog-box template if the dialog box should appear when the parent window is created. Otherwise, you must call ShowWindow. For further dialog-box styles and their application, see the DLGTEMPLATE structure in the Platform SDK and Window Styles in the MFC Reference.

if you have a class Dialog you can use
<br />
riporto * dlg;<br />
dlg = new riporto();<br />
dlg->create(IDD_RIPORTO);<br />
dlg->ShowWindow(1); <br />

Move the call to Create() to the constructor:
riporto::riporto( CWnd* pParent ) : CDialog(riporto::IDD, pParent)
{
Create(IDD);
}Now you can create and display the dialog via:
riporto *pDlg = new riporto;
pDlg->ShowWindow(SW_SHOW);
...
pDlg->DestroyWindow(); Desmo16 wrote: the application runs but crashes at runtime

I have a function in cpp file returning int * array and taking int * array as a parameter. It is as:
int * funcArg(int *a ) {
int DLLArg [] = {100,200,300};
a=DLLArg;
return a;
};
I have exported this function in the dll (i have checked it with dumpbin.exe)
But I can not handle this function in c# client. My code in c# is as: ( ıt gives this error. "An unhandled exception of type 'System.Runtime.InteropServices.SafeArrayRankMismatchException' occurred in CSharpClient.exe
Additional information: Safe array of rank 51241 has been passed to a method expecting an array of rank 1."
What should I do? URGENT help!!!
namespace CSharpClient
{
class Class1
{
[DllImport("DenemeNonMfcDll.dll",EntryPoint="?Sub@DLLclass@@QAEHHH@Z")]
public extern static int Sub(int a, int b);
[DllImport("DenemeNonMfcDll.dll")]
[return: MarshalAs(UnmanagedType.SafeArray)]
public extern static int [] funcArg(int [] a);
public static int [] intArray = new int [3] {0,1,2} ;
static void Main(string[] args)
{
foreach (int num in funcArg(intArray) )
{
System.Console.WriteLine(num.ToString());
}
Console.WriteLine("Press any key to continue...");
Console.ReadLine();
}
}
}

You are trying to return a pointer to an array on the stack. There is no guarantee that your array will still be there when your function returns. You are passing in a parameter "int *a" which you never use.
Was this your intention?
int * funcArg(int *a)
{
a[0] = 100;
a[1] = 200;
a[2] = 300;
return a;
};
Most people usually have another parameter for the calling function to tell the callee the size of the array being passed so the callee won't exceed the buffer.

My aim is to write a function returning int array and taking an int array as a parameter such as
int * funcArg(int *a){
return a;
};
I will export it from c++ dll and I will use this function in c#. I will call it like
[DllImport("DenemeNonMfcDll.dll")]
[return: MarshalAs(UnmanagedType.SafeArray)]
public extern static int [] funcArg(int [] a);
But C# can not handle it this way. And I coul not find a way doing this. Either I can change c++ code or c# code. But I could not find a solution to make an interoperation between c++ and c#

Remove the default border if necessary
OnPaint, or in OnEraseBkgnd draw a line

Right click on a dialog box while in design mode and see if a menu pops up. If it does so, then see what is there with it. Nobody will *send* you the code for anything. You may have to code and when you run into trouble someone can help you.

You can use ModifyStyle function to remove or add a window style and ModifyStyleEx for add/remove extended style.
for removing border, ModifyStyle(WS_BORDER,0);
for removing caption ModifyStyle(WS_CAPTION,0);

check MSDN for more details about windows styles.
in the OnPaint function,
CPen pen;
pen.CreatePen(PS_SOLID,GetSystemMetrics(SM_CXDLGFRAME),GetSysColor(COLOR_ACTIVEBORDER));
dc.SelectObject(pen);
CRect rect;
GetClientRect(rect);
dc.MoveTo(dsierd_x_pos,desired_y_pos);
dc.LineTo(xpos,ypos);
do the necessary claculation to draw your line

1) Insert a dialog bar resource
2) Create a CDialogBar object in your CMainFrame class
3) Inside CMainFrame::OnCreate(...), create your dialog bar as below
if(m_wndDialogBar.Create(this, IDD_DIALOGBAR, WS_CHILD | WS_VISIBLE | CBRS_BOTTOM, IDD_DIALOGBAR) == false)
return -1;
...
m_wndDialogBar.EnableDocking(CBRS_ALIGN_BOTTOM);
...
DockControlBar(&m_wndDialogBar);

If by upper side you mean the title bar, you can just remove it in the Title bar property of your dialog
ashish dogra wrote: but i am using Dialog based in mfc not SDI
Isn't that easier? If you want it to look like a dialog bar at the bottom, just drag a group box control and place it at the bottom. Modify the styles if you need to. Now place your buttons or whatever in it. Doesn't it look like a dialog bar now?

If you wanna do all these color customization, i suggest you create a class derived from CStatic and do it in there. Then in your dialog, place a static control and subclass it with the class you just created.
