is ur dll created with MFC? if yes, add this AFX_MANAGE_STATE(AfxGetStaticModuleState()); at the beginning of your exporting function in dll.

if u r using HWND CreateDialog(HINSTANCE hInstance,LPCTSTR lpTemplate, HWND hWndParent,DLGPROC lpDialogFunc); to create a dialog, make sure the parameter hInstance is correctly dilivered, it must be the dll module's instance.

BOOL WINAPI DllMain(HANDLE hinstDLL, DWORD dwReason, LPVOID lpvReserved); the first parameter is the dllmodule's instance.

Are there any other controls on the dialog that are not being displayed? If so, it sounds like a secondary thread is needed as the UI thread is too busy servicing other messages.

Did you saw MSDN for LNK2001
From the MSDN:
"unresolved external symbol "symbol"
Code references something (such as a function, variable, or label) that the linker can't find in the libraries and object files."

Add your cpp file to your solutions explorer (I'm assuming you're using VS7.1), or File View (if using VS 6.0).
This tells the compiler where to find the implementation of the class definitions.

How to hide (or not to create) the menu of an SDI project generated by the wizard code of VC++ 2005? Thanks!

I figured it out.
1) To hide the menu, according to the source code of CDocTemplate, we have to do this way:
pDocTemplate = new CSingleDocTemplate(
0,
RUNTIME_CLASS(CTextEditorDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CTextEditorView));
2) Then we will see the icon of the application not being loaded. We have to load it in CMainFrame::OnCreate.
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);

If you don't want the wizard created Menu at any time in your application then simply remove the IDR_MAINFRAME menu resource from your application. If you want to use it in some time then change the ID of the menu from IRD_MAINFRAME to some other

there's no default constructor defined in your class. you should pass the bool value to the CSentenceArray class.
i.e the implementation code of CSentenceList constructor, you should pass teh bool value to as initialization list
CSentenceList::CSentenceList(bool bCreateArray) : CSentenceArray(bCreateArray)
{
}
hope it's clear

I think that's what I'm doing actually...
#include "StdAfx.h"
#include ".\sentencelist.h"
CSentenceList::CSentenceList(bool bCreateArray) : CSentenceArray(bCreateArray)
{//Code}
CSentenceList::~CSentenceList ()
{}
Error:
error C2512: 'CSentenceArray' : no appropriate default constructor available
error C2436: 'CSentenceArray' : member function or nested class in constructor initializer list

Make sure you have the equivalent of a default destructor by giving the parameters of your constructor default values. "C++ will not attempt to create a default constructor for you if you declare one" (Effective C++ Third Edition - Scott Meyers)
Try this in your declaration in the header file...
CSentenceList(bool bCreateArray=false);
|
|
|
|
|
I tried adding a default value, even in the base class, but it's still unsuccessful.
CSentenceList::CSentenceList(bool bCreateArray = false) : CSentenceArray(bCreateArray = false)
{int x = NULL;}
CSentenceList::~CSentenceList ()
{}

No, your putting it in the implementation section.
Put it only in the declaration in the header file.

Not per the code you've shown. The compiler is telling you exactly what the problem is. CSentenceArray has no default constructor.
class CSentenceArray
{
public:
CSentenceArray( void );
};

You have declared a function called CSentenceArray in the CSentenceList class. I suspect this is hiding the CSentenceArray class constructor. Remove or rename this function, I'm pretty sure this is illegal anyway and you're just getting a poor diagnostic message from the compiler.
Stability. What an interesting concept. -- Chris Maunder

Thats just passing the parameter to the base class which is correct, otherwise the base class will not get any parameters to initialize with. The class declaration shows CSentenceList is derived from CSentenceArray...
class CSentenceList :
// Sentences stored as a linked list
public CSentenceArray

Oh crud, I just spotted what you were talking about. I missed that the first time around. You are right. That doesn't look quite right...
protected:
void CSentenceArray(bool bCreateArray);
virtual void storeSentence(const char *pszSentence);
virtual void swapWithNext();
virtual int HowManyWords(const char *pszWord);
};

Hi everybody,
My question is how to convert this c++ code to javascript or html that can generate the result random number?
#include <cstdlib>
#include <ctime>
#include <iostream>
using std::cout;
int main( ) {
srand( ( unsigned )time( 0 ) );
int randomKey = rand() % 4013;
cout << "Your random key is: " << ( 10016486 + ( randomKey * 22423 ) ) << "\n";
system( "PAUSE" );
return 0;
}
Thanks for any help
