Adjust the size of the non-client area of the window (in OnNcCreate()) and paint the title in the non-client area.

Ryan,
Thanks for the help. I don't see an OnNcCreate() in the ppc framework. I thought it would be part of the CWd class but I don't see it defined. I tried altering the CREATESTRUCT in the PreCreateWindow and setting the cy attribute to 300 since the screen is 240 x 320. This I was hoping would give me 20 pixels to work with at the top of the screen.
When you say adjust the non-client area are these actual members of the CWD class?
Thanks again for the help,
-Eric

I need to get a Modal-Dialog's handle (HWND) before I enter the blocking DoModal() call.
The thing is the Dialog is only created inside DoModal().
Is there a way to create it in some way and then call DoModal() seperately ?
|
|
|
|
|
|
I need to call DoModal(), I need a Modal dialog that blocks everything else.
I just need to create it before entering the modal loop.

Why??
Put your code inside OnInitDialog() or OnCreate() in your dialog.

if you r planning to intialize any variable then you can just write some function in the dialog class and call these just by creating the Object of the class and calling the function before calling domodal
Thanx
TAKE CARE

This specific dialog doesn't need to knwo to do special stuff in it's OnInitDialog().
What I did eventually was send it a pointer to :
class CRunner
{
public:
virtual void Run() = 0;
};
but I'm still looking for a better way, as in externaly creating the dialog, accessing it's HWND, then entering the Modal-Loop.
Does someone have an example of creating the dialog Modeless, and then entering some sort of message-pumping loop that would make it modal ?
thanks

I don't have the exact code, but you can do something like this:
CMyDlg dlg = this;
dlg.Create(dlg.IDD);
HWND hWnd = dlg.m_hWnd
EnableWindow(FALSE);
dlg.CenterWindow();
dlg.ShowWindow(SW_SHOW);
int nResult = dlg.RunModalLoop(MLF_SHOWONIDLE);
dlg.DestroyWindow();
EnableWindow(TRUE);
You can also check out MFC's code for DoModal.

Usually for this is used following method:
_CrtDumpMemoryLeaks();
From here:
http://msdn.microsoft.com/library/d...akdetection.asp
#define CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
# other includes
Note The #include statements must be in the order shown here. If you change the order, the functions you will use may not work properly.
_CrtDumpMemoryLeaks();
I call at destructor of COM class.
Which is generated with standard COM attributes,
All Debug information is (probably) generated.
But this is not generates string numbers of leaks...
Why so?
Thanks.
__________ my stdafx.h
#define _CRTDBG_MAP_ALLOC
#include <atlbase.h>
#include <atlcom.h>
#include <atlctl.h>
#include <stdlib.h>
#include <crtdbg.h>
Outputs only "_CRT_NEW" leak strings locations...
Not useful...

hello im a kinda newby c++ programmer,im currently writing a socket client\server application under the windows platform.
i have established a connection between my client server app and also made my client send data,i know the client is sending corectly coz i tested it with netcat,however the server wont recive any of the text data that i am sending from the client. my problemb is with the recv(); i have seen working code that recives data in a console app but i just cant incorporate it into my mfc server.
it must only be a little mistake i am making but its really bugging me,any help or info regarding the recv function from a mfc point of view would be much appriciated
thanks 4 your time

I don't understand your problem. What is your trouble with recv? Don't you receive data?
Do you send text data or binary data? Maybe you can provide the piece of code where you use recv.
|
|
|
|
|
int nBytes;
CString buffer;
nBytes = recv(Socket,buffer, sizeof(buffer), 0);
// check for errors
if (nBytes == SOCKET_ERROR) {
m_strStatus = "Recv Failed";
UpdateData(false);
}
else
{
// print the received message
m_strStatus = "Message Received";
m_strMessage = buffer;
UpdateData(false);
}
there is my code for the recv function,at the moment it wont compile,its complaining that it cant convert from class CString to char*.
im tryning to send text to the server,the text should be displayed in my editbox varible named m_strMessage.sometimes i do get some text in there but it isnt from the client i only assume its some sort of error code.
i have tried all sorts tryna get this to work for you it might pretty simple however im just a newby.
thank you for your time m8!

You have to wait until you receive data.
while(y=recv(conn,(char*)&mlMsgRecv, sizeof(mlMsgRecv),0))
{
...
}
Have a look at the following article which is a very good tutorial for the first socket steps:

Hi !
My application has several instances of different objects. Some of these have to be persistant and have to be stored in a relationnal database.
I guess it would be better that my persistant objects don't know about the database, but I don't know how I should implement that. Should I have a global class knowing every persistant objects and being able to store, retrieve, delete any objet in the database ? Or should I rather have one object knowing the database for each type of persistant object ?
I would appreciate to get some hints or suggestions from you !
Thanks !
Jerome

If your objects are derived from MFC's CObject, why not just create a CMemFile, Archive the object to the memfile, and store the resulting buffer into an image/blob column in the database?
onwards and upwards...
|
|
|
|
|
Thanks for your answer, but I'm not using MFC !

Then you need to add a Store and Load method to your object that will save/load the state from a buffer.
onwards and upwards...

this does exactly what you are trying to do.
as much as i know an updated version is in the boost library now: (www.boost.org[^]).
The only problem is that you have to install the whole shebang just for this.
if you want to do it the dangerous way, you can use the standard c string function strtok (i don't like it at all and it has many disadvantages)
hope this helps,

The problem is, i can't use c string function for this assignment... so have to use c++ function to do this..
|
|
|
|

it's better and more straightforward anyways (if you are into stl)

you can always use strtok.
