You mean the child window is not getting resized?

Hello,

The child window is getting resized but when I press the maximize button of the child window , the whole of child window is seen without the main window having the restore button.The child window is now seen as the main window without the restore button.

hello,

The TableFrame's CreateFrame() is creating the Child Window and when the maximize is pressed the OnSize() is called.

TableFrame::CreateFrame()
{
if(!CMDIChildWnd::Create(NULL, FrameName , WS_VISIBLE | WS_CHILD |
WS_BORDER |WS_MAXIMIZEBOX | WS_MINIMIZEBOX |
WS_THICKFRAME | WS_OVERLAPPEDWINDOW
|WS_VSCROLL | WS_HSCROLL ,
WindowSize(), pFrame, NULL))
{
TRACE0("Failed to create view window\n");
return false;
}
}

void TableFrame::OnSize(int nType)
{
switch(nType)
{
case SIZE_MAXIMIZED :
{
CRect ParentRect;
MDIMaximize();
break;
}
}
}

Is TableFrame derived from CMDIChildWnd?

hello,

thanks for your replies.
yes TableFrame is derived from CMDIChildWnd

Why are you calling MDIMaximize() from OnSize?

I just tried it in a sample application. But could not find any problem... If you can please mail me the source. It is ns.nest@gmail.com

Hello,

I am using MDIMaximize() to maximize the child window. I ll try to post the code.

Thanks,

I shall check the code... may be a little bit later... Wink | ;)

Problem can be solved by calling CMDIChildWnd::OnSize in TableFrame::OnSize.

Hello,

Thanks ,
Now I am getting the minimize,restore,close buttons for the child window and minimize,maximize,close buttons for the main window but it looks like the minimize,restore,close buttons for the child window does not have a handler function
but the main window's button handler is the TableFrame's OnSize().

Ya... I found that but didn't get enough time to resolve that...

Hi,
I'm hacking at this now for several hours, it will not compile.
I've the following declaration

<br />
class CCmdLineParserApp;// Advance Declaration<br />
typedef BOOL (CCmdLineParserApp::*PFN_CMDLINE_ACTION)(LPCSTR pAction=NULL);<br />
<br />
typedef struct {<br />
	char Switch[16];<br />
	PFN_CMDLINE_ACTION pCmdAction;<br />
	BOOL bIsTerminal;<br />
}CMD_LINE_ENTRY,*LP_CMD_LINE_ENTRY;<br />

Later on in the code I've found a LP_CMD_LINE_ENTRY pE. I try to execute
the Relevant pCmdAction function as follows:-

<br />
  (pE ->*pCmdAction)(ResultString);<br />

I get:

C:\Projects\CmdLineParser\CmdLineParser.cpp(143) : error C2065: 'pCmdAction' : undeclared identifier
C:\Projects\CmdLineParser\CmdLineParser.cpp(143) : error C2297: '->*' : bad right operand

I do not use this syntax very often, and I'm obviously making a very silly syntactic mistake. Any ideas??

regards

Where is pCmdAction declared? I don't see relevant code in your post
that would cause the error.

pCmdAction is a member of structure CMD_LINE_ENTRY. CCmdLineParserApp, which is derrived from CWinApp, contains a static array of these. pE is a pointer into that array, and hence points to a structure of type CMD_LINE_ENTRY.

You need to precede this with an instance of CCmdLineParserApp, like:

CCmdLineParserApp c;
(c.*(pE->pCmdAction))(ResultString);

No, I forgot to tell, the code snippet is called from within a memberfunction of CCmdLineParserApp.
however I tried :(this->*(pE ->pCmdAction))(ResultString) and it worked. Have no Idea why.

Because you were trying to call a CCmdLineParserApp method using a pointer
to a CMD_LINE_ENTRY as the CCmdLineParserApp object.

In your fixed version, "this" is the CCmdLineParserApp object the method is being
called in the context of, and "pE->pCmdAction" is the pointer to the method.

Much better Smile | :)
