You will have to call the function from a different thread, but it should work. You won't be able to use the MFC window pointer. You'll need to use the m_hWnd member of the CWnd pointer. But yes, it should work after clicking on a button from your dialog.
You will need to declare hwndYesButton as an HWND and get the window handle of the yes button (not an easy task. I'm not sure exactly how to do it).

Do you think that sending a WM_CLOSE message to the dialog would take of everything? I have done it with a Splash window that I designed once and yes I used a thread for it.

Hmmm, maybe. Remember that the MessageBox() function returns a value depending on which button was pressed. What does it return in it gets a WM_CLOSE. His code will have to make sure that it does the right thing...

It always returns zero (if the window processes the message). I think Aleon just wants to close the dialog. But if it is a modal dialog box then EndDialog can be used and the result can be passed as a parameter. If not then your answer still remains the best solution (in my opinion).

Simply tell the dialog to shut up and I don't know what could be wrong with you. What kind of symptoms are you experiencing?  Just joking.
Seriously, Ryan's last post gives you the correct answer. Where exactly are you calling PostMessage and SendMessage?

Actually, I am an "engineer" but since I cannot find a job I think I should consider your suggestion. It would be so much fun to play with peoples' minds and tell them that they are crazy when they're just fine.

Hello,
I have a already built application using MFC. This application uses Context-Sensitive help ( While building they choosen a Context-Sensitive help option for Dialogbased application). The hlp folder of this application contains "afxdlg" rich text document ( this comes by default ).
I want to modify this file to add my own document. But when i modified and recompiled using Help Work Shop the following
error is coming :
C5011: Error: D:\MFC_help\HelpTest\hlp\afxdlg.rtf :
Cannot open the file "{\rtf1\ansi\ansicpg1252\uc1 \deff0\deflang1033\deflangfe1033{\fonttbl{\f0\froman\fcharset0\fprq2{\*\panose 02020603050405020304}Times New Roman."
How can i avoid this and compile with out any error ?
Thank you.

I have an array in a struct and I am trying to allocate the correct memory size for the data that I need to put in it.
My data is words read from a file.
exp:
deg
active,frozen,stopped
ft/sec
meters
gallon
etc......
If I create a char array can I make each one of those an element of the array?
sj

127 for char
255 for unsigned char
[EDIT]
You can find this info in limits.h in the include dir of VC++.

a char is a single byte so the highest value if cast as an integer would be 255 unsigned or 127 signed.
It sounds like you are actually asking about the max length of a char array. This would be determined either statically by the defining your array like:
// pick a number that is longer than your longest word
#define MAX_WORD_LENGTH 20
// if you know how many words you will conceivably have
#define MAX_WORDS 100
char words[MAX_WORD_LENGTH][MAX_WORDS];
If this definition is made locally - you'll be limited by the size of your stack. If made globally, you'll be limited by your data segment size - or something like that
If you don't know how many words you will have or how long they could possibly be then you'll need to pre parse the file and determine how many words there are and how long the longest one is. Then you could use
char* buffer;
buffer = (char* )malloc(NUM_WORDS*LONGEST_WORD);
I'm going to live forever or die trying!

If I know a font's name, how I can acquire its character set?
typedef struct tagLOGFONT { // lf
LONG lfHeight;
LONG lfWidth;
LONG lfEscapement;
LONG lfOrientation;
LONG lfWeight;
BYTE lfItalic;
BYTE lfUnderline;
BYTE lfStrikeOut;
BYTE lfCharSet;
BYTE lfOutPrecision;
BYTE lfClipPrecision;
BYTE lfQuality;
BYTE lfPitchAndFamily;
TCHAR lfFaceName[LF_FACESIZE];
} LOGFONT;
We know “BYTE lfCharSet;” may set a font’s character set, but I don’t know how acquire it’s all character set?

Use EnumFontFamilies() (or EnumFontFamiliesEx()). The ntmCharSet field in the NEWTEXTMETRIC structure passed to your callback function should do the trick
Hope this helps,

May you tell me detailed information? thank you.

|

Try this:
int CALLBACK FontProc(ENUMLOGFONTEX *lpelfe, NEWTEXTMETRICEX *lpntme, int FontType, LPARAM lParam)
{
*(BYTE*)lParam = lpntme->ntmentm.tmCharSet;
return 1;
}
BYTE GetFontCharSet(LPCTSTR lpszFont)
{
CClientDC dc(NULL);
LOGFONT lf;
lf.lfCharSet = DEFAULT_CHARSET;
_tcscpy(lf.lfFaceName, lpszFont);
lf.lfPitchAndFamily = 0;
BYTE bCharSet = DEFAULT_CHARSET;
EnumFontFamiliesEx(dc.m_hDC, &lf, (FONTENUMPROC)FontProc, &bCharSet);
return bCharSet;
}It should work, although I haven't tested it. It basically outlines what you need to do.
Hope this helps,

I am developing a project using .NET Remoting technology to achieve the talk between client and server. The shared object interface in the server is written in C# and compilered into a DLL, which will be used in the client code. So how to access the object in the C# DLL?Here are the source code:
=======IInfoMan.cs->IInfoMan.dll===========
using System;
using System.Runtime.Remoting;
namespace InfoMan
{
///
/// Summary description for IInfoMan.
///
public interface IInformationManager
{
string DataItem(int whichItem);
int DataCollectionLength();
}
}
and Here is the implementation for the interface
=======InformationManager.cs========
using System;
using System.Runtime.Remoting;
namespace InfoMan
{
///
/// Summary description for InfoManager.
///
public class InformationManager: MarshalByRefObject, IInformationManager
{
private string[] theData = new string[ARRAY_SIZE];
private const int ARRAY_SIZE = 3;
public InformationManager()
{
theData[0] = "In a village of LaMancha, ";
theData[1] = "the name of which I have to desire ";
theData[2] = "to call to mind, there lived ";
}
public string DataItem(int whichItem)
{
string theItem = null;
if(whichItem >= 0 && whichItem < ARRAY_SIZE)
{
theItem = theData[whichItem];
}
return theItem;
}
public int DataCollectionLength()
{
return ARRAY_SIZE;
}
}
}
I know that I should use #using keyword to use the C# dll in the Visual C++ code. That is #using "IInfoMan.dll" and also #using <mscorlib.dll>. But when I tried to using the following codes to connect to the server and create a instance of the remote object, I got the error message. Why?
try
{
::RemotingConfiguration::Configure(S"AioTest.exe.config");
InformationManager *m_InfoMan = new InformationManager();//Maybe this line has an error.But I don't know why.
}
catch(Exception * exp)
{
CString msg = exp->Message;
MessageBox(msg);
}
error C3828: 'InfoMan::InformationManager': placement arguments not allowed while creating instances of managed classes
Can someone help me to solve the problem? Thanks!

error will occur if i choose "using MFC in a shared DLL" in menu "project setting" and build,while no error happen if i choose "using MFC in a static library" and build,why?
the error infomation is as follows:
Bank2.obj : error LNK2001: unresolved external symbol __imp__InternetAttemptConnect@4
D160ABank.obj : error LNK2001: unresolved external symbol __imp__FtpGetFileA@28

D160ABank.obj : error LNK2001: unresolved external symbol __imp__InternetOpenA@20
Debug/Bank2.exe : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.
the problem is how can i build it successfully in "using MFC in a shared DLL" choice.
be friends
