put the above code after like this //}}AFX_DATA_MAP
<blockquote class="FQ"><div class="FQA">stevepqr wrote:</div>DDX_Control(pDX, IDC_TINY1, m_Tiny[0]);
DDX_Control(pDX, IDC_TINY2, m_Tiny[1]);
DDX_Control(pDX, IDC_TINY3, m_Tiny[2]);
.
.
.
DDX_Control(pDX, IDC_TINY12, m_Tiny[11]);</blockquote>
in DoDataExchange Function. It should work.

Thanks but the code is already included inside the '//}}AFX_DATA_MAP' I didn't change this part just added lines inside the markers.
|
|
|
|
|
i had the same problem and this was solved by adding the code outside the markers.

ClassWizard only parses the lines inside its comments.
You should place your custom lines outside the class wizard's special comments. Just below the comment line //}}AFX_DATA_MAP, for example.
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TINY1, m_Tiny[0]);
DDX_Control(pDX, IDC_TINY2, m_Tiny[1]);
You should also take definitions into account in header file.
enum { IDD = IDD_DIALOG1 };
CStatic m_static1;
CStatic m_Tiny[12];
The lines added manually in that way, won't be parsed by ClassWizard.

I thought of this already - when I try it I get 'Cannot Add New Member' when I try to add a new member but otherwise it works ok. I'm getting round this by commenting out the above lines adding new members and then uncommenting them, PITA!!

The problem may be with <your project="" name="">.clw file. Close project then rename that file. ClassWizard will re-create it. Or you may edit yourself if you know what you do.

Thanks! Deleting the .clw and regenerating it did the trick - strangely, after recreating it I had to exit VS and restart but now all is good.
Thanks to everyone else too for their suggestions.

I am trying to Saving and Restoring Toolbars status by sending TB_SAVERESTORE message. MSDN says if you don't have user data to store with the toolbar buttons, you don't need to handle TBN_SAVE or TBN_RESTORE notification. So, now, the saving and restoring are fine, the program restores toolbar buttons correctly. However, if I try to kill that toolbar control restored, Visual Studio gives a warning message "Unhandled exception at 0x7c901230 in win32tst.exe: User breakpoint." This warning only shows if the program is launched inside the Visual Studio. It just runs fine if launched outside of Visual Studio. So I tried to debug with WinDbg.exe, and it gives a more detailed description of that user breakpoint warning "Invalid Address specified to RtlFreeHeap". Anybody knows what's wrong with the restoring? Thanks.
case WM_NOTIFY:
{
switch (((LPNMHDR)lParam)->code)
{
case TBN_GETBUTTONINFO:
{
LPTBNOTIFY lpTbNotify = (LPTBNOTIFY)lParam;
// Pass the next button from our array. There is no need to
// filter out buttons that are already used; they will be
// ignored.
int buttonCount = sizeof(tbButtons) / sizeof(TBBUTTON);
if (lpTbNotify->iItem < buttonCount)
{
lpTbNotify->tbButton = tbButtons[lpTbNotify->iItem];
return TRUE;
}
else
{
// No more buttons.
return FALSE;
}
}
break;
case TBN_QUERYINSERT:
case TBN_QUERYDELETE:
return TRUE;
case TBN_ENDADJUST:
{
TBSAVEPARAMS tbSave;
tbSave.hkr = HKEY_CURRENT_USER;
tbSave.pszSubKey = "Software\\key";
tbSave.pszValueName = "tbsave";
SendMessage(GetDlgItem(hWnd,ID_TOOLBAR),TB_SAVERESTORE, TRUE, (LPARAM)&tbSave);
}
return TRUE;
}
}
break;

We have a huge C++ code, developed on Microsoft Visual Studio 6.0. This contains but server and client code. Now the requirement is to add a support for memory leak detection.
So can any one help me to code, which should check the existing whole code base for memory leaks.
Thanks,
Nandu

Thanks, But the above mentioned will not support VS6.0, I need a similar solution for VS 6.0

Help me with these program
/* program to illustrte read function with pointer */
//this program may not work properly because of memory problems in read
#include<stdlib.h>
#include<stdio.h>
#include<unistd.h>
#include<string.h>
int main()
{
char *buf,c;
int nread;
memset(buf,0,0);
buf=malloc(1024);
nread=read(0,&buf,100);
printf("characters read: %d\n",nread);
if(nread == -1)
{
write(2,"An error occured in read function\n",27);
}
else
{
if(nread==0)
write(2,"Data is not written to the filedescriptor\n",27);
else
write(1,&buf,nread);
}
free(buf);
}
output:
sandeep@sandeep $ ./a.out <x
characters read: 75
this is Kead program
which is throwing lots of errore
lets correct them
Segmentation fault

You have to call malloc before calling memset. Otherwise, you will try to write into an invalid pointer.

|
|
|
|
still I am getting the error
|
|
|
|
|
And for the read and write functions, don't pass the address of your buffer variable: it is already a pointer. Pass the pointer directly:
read(...,buffer,...);
(apply that for every read and write).

|

thanks it solved
thankyou

You should use buf, not &buf.
For instance
nread = read(0, buf, 100);
BTW your code is a mess, you really need a good C tutorial.

class CA{
private:
int m_Var;
public:
CA(int x=0): m_Var(x){cout<<"1";}
bool operator < (const CA &obj2) { cout<<"2"; return (m_Var < obj2.m_Var) ? true : false;}
};
int main(void) {
CA obj1=2;
if(obj1 < 3){cout << "In If block" << endl;}
}
the output of this code is 112In If block .. i can understand the reason behind the first 1 and "2In If block" .. i dont understand when the second 1 is being called?
as per my understanding when (obj1<3) executes it may call obj1.operator<(3)
But constructor is being called but whats makes it to call?
kindly explain why the second 1 is being displayed?

Not actually. It is actually called like
obj1.operator<( CA(3));// A local temporary object is created here.
Here the integer 3 is automatically converted to a CA object by involking the constructor. Such conversions are called implicit conversions. You can prevent such conversions using the explicit keyword[^]

You are so fast!

Because constructor accepts a int.
Member 3974347 wrote: as per my understanding when (obj1<3) executes it may call obj1.operator<(3)
Your operator overload accepts const CA & but you specified the expression obj1<3, since type CA has a constructor which takes int, a temporary will be created by passing 3 to the constructor of CA and this is the reason for the second time constructor call.
Use explicit keyword to avoid the confusion.
