To SendMessage how to send a string as argument
and how to recieve and display that string
lets say in a edit box i have some text ABCD , i want to capture this text to a CString and pass this CString to Sendmessage as Wparam parameter to other remote process(iam using sockets for remote connevtion). and at remote Application i will capture this wparam and display the message
how to do this using send message.
Thanks in advance

You don't use SendMessage to communicate to another process using a socket.
Also, don't cross post.

SendMessage is for sends a message to the window

I suggest don't use SendMessage to send the data between client and server.
Go through the following sample you will get the solution how to send the CString to remote process.

Hello!
Is there a way in MSVC (VS 2005) to programmatically change which tab is selected? I've found references to a SetActiveTab, but it doesn't seem to be part of MS C++.
I've done this, from within a page:
CPropertySheet* mySheet = (CPropertySheet*)(GetParent());
CTabCtrl* myTab = mySheet->GetTabControl();
myTab->SetCurSel(iNewIndex);
...but SetCurSel only changes the tab itself - no WM_NOTIFY is sent, so the page itself is not switched - useless...
Help!
Thanx!
~ Mike

Why not just use CPropertySheet::SetActivePage()?

This works like a charm -
I have no idea how I missed this member func -
Thank You!

Hello,
and when you call:
myTab->SetActiveTab(iNewIndex);
what hapens?
regards
break;
|
|
|
|

That tab moves to the front, but the displayed page remains unchanged - SetActiveSheet does the trick -

Hello,
I have now one question for you, i use CTabCtrl, an i like to disable all other tabs with index > 0
when my program is active, can you do this with this CPropertySheet control??
Do you know how to do this(disable tab items) with CTabCtrl?
thanks

First of all, I'm not even sure if the topic makes sense.
I'm using native C++ compiler (Dev-C++). Anyway, I'm new to network programming and have been doing little project on network communication between two computers using WinSock (just sending and receiving string). And then I just had an idea whether this kind of "communication" will also work for FTP servers. I tried it on an ftp server on port 21. I requested connection and, to my surprise, I received a welcome message from it. But then I have no clue how to send commands/requests at all (USER or PASS). I would assume the problem is either I don't have the correct string format, or the socket type is just different (I don't have any clue about network types very much). Or maybe Winsock is just not meant for it? Please advise me on what's actually going on.
I know there are alot of free libraries out there, but I want to know what's actually happening behind it, in terms of protocols.
Thanks!
PS: Not sure if this belongs to the correct board, but move it as you wish.

Very possible. You're on the right track: it's all about the protocol - what sequence of bytes
to send and receive and when to do it.
A Google search on "FTP protocol" will get you links to more than you ever wanted to know about
FTP. It's been around for a long time 
I think this is the official specification: FILE TRANSFER PROTOCOL (FTP)[^]

Thanks, Mark! You encouraged me to find the problem why my "USER YYYY" does not produce any reply. It turns out I had the wrong CRLF closing bytes. Now at least I can do USER and PASS. =) It's getting more interesting. Thanks!

Just remember Andrew that you need at least two channels, one to issue the commands and one to transfer the data.
Good luck!

Using VS2005/VC8:
I've tried the following, and all I get is a single-pane window with no client edge:
int CSplitterViewTestView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
CCreateContext context;
memset(&context, 0, sizeof(CCreateContext));
CRect cr;
GetWindowRect(&cr);
int nHeight = ::GetSystemMetrics(SM_CYSCREEN);
if (!m_splitterWnd.CreateStatic(this, 2, 1))
{
AfxMessageBox("Error setting up splitter window", MB_ICONERROR);
return FALSE;
}
context.m_pNewViewClass = RUNTIME_CLASS(CGridCtrlView);
if (!m_splitterWnd.CreateView(0, 0, RUNTIME_CLASS(CGridCtrlView), CSize(cr.Width(), nHeight), &context))
{
AfxMessageBox("(CGridCtrlView) Error setting up gridctrlview pane objects.", MB_ICONERROR);
m_splitterWnd.DestroyWindow();
return FALSE;
}
context.m_pNewViewClass = RUNTIME_CLASS(CWaitingView);
if (!m_splitterWnd.CreateView(1, 0, RUNTIME_CLASS(CWaitingView), CSize(cr.Width(), 0), &context))
{
AfxMessageBox("(CGridCtrlView) Error setting up waitingview pane objects.", MB_ICONERROR);
m_splitterWnd.DestroyWindow();
return FALSE;
}
m_splitterWnd.RecalcLayout();
return 0;
}
I get no errors at all.

[EDIT]
If I change the CreateStatic call as follows:
if (!m_splitterWnd.CreateStatic(GetParent(), 2, 1))
The following anomalies appear (yes, more than one):
1) The toolbar doesn't display
2) The status bar doesn't display until I drag the bottom border of the app over something gray.
3) I can't get a the splitter bar to react until after I resize the window once.
4) After letting go of the splitterbar, I can't move it again.

AFAIK a CSplitterWnd can only be created in a CFrameWnd or CFrameWnd derived window. At least I have never had any luck when I tried to use it elsewhere.

Yeah, I got it to kinda work, but saying it's flakey is putting it mildly.

Check your cr (CRect)....I don't think the WindowRect will be known in OnCreate().
Maybe try an arbitrary size in the CreateView() calls (something like CSize(100,100) just to make
sure it works.
Once you get a WM_SIZE message then you can set the panes to the real size you want.
RecalcLayout() is un-necessary here as well, I believe, for the same reason - the size is not
known yet.

Oh yeah....good point by PJ Arends!!
In a non-frame window you're going to have to resize the splitter window in a WM_SIZE handler,
which is extra fun with a toolbar involved Way easier to use a CFrameWnd-derived window,
in which case you can create your splitter (and toolbar, status bar, etc) in OnCreateClient().

I believe PJ is correct. When I want splitters inside a view I always use Paul DiLascia's CWinMgr[^].

After 4 years I found this thread...
I solved the problem with a MoveWindow after the call (maybe unuseful) to RecalcLayout, and I also provided the method IsFrameWnd in my container View that returns TRUE.
It seems to work

Post the fix then. I no longer work in C++/MFC, but I'm sure others would be interested in what you found.
