Thanks AnShUmAn,

Looking forward to your reply. I do not know why for the same breakpoint setting for x64 binary, we only break once, and for x86 binary, we break twice.

Dear All
in a project I need to load a DLL more than once. (15 times at least)
This DLL is used to compress raw voice into mp3 format.
Is it possible to do this.
If there is any points which I should consider please let me know.
Regards
Monhi

The DLL which I want to use is a mp3 compressor which only compresser the sound of a channel.
But I need to do the same job for 15 channels at least.
Thus it was neccessary to load it more than 15 times.

Well, if I need to use the same function in different threads, I don't load the corrensponding DLL many times...

void CTestgarbageDlg::OnButton1()
{
SHFILEOPSTRUCT shop;
shop.hwnd = this->GetSafeHwnd();
shop.wFunc = FO_COPY;
shop.pFrom = _T("c:\\AUTOEXEC.BAT\0");
shop.pTo = _T("d:\0");
shop.fFlags = FOF_FILESONLY;
int iRet = -1;
iRet = SHFileOperation(&shop);
if (iRet == 0)
{
AfxMessageBox(_T("sucess"));
}
else
{
AfxMessageBox(_T("fail"));
}
}
I've tried the code above, it works fine. Hope it helps you.

Why do you double terminate the strings?
Nevermind, it was my ignorance.

Documentation says to end it with two null chars.
Rajesh has verified it it works with single null termination also.

Hi,
I am working in MFC and i am having a chat dilaog box in which there is an edit box. I want to send send what the user is doing on the edit box used for sending message. For this I am using the notificatio ON_EN_CHANGE();
I have declared it as follows in My Class COperChatDlg:
afx_msg void OnChangeEdit();
ON_EN_CHANGE(IDC_EDIT_OP, OnChangeEdit)
and defined it as
void COperChatDlg::OnChangeEdit()
{
static bool bSend = false;
CString strText;
GetDlgItemText(IDC_EDIT_OP,strText);
int nTextLen = strText.GetLength();
if(!bSend)
{
bSend = true;
SendOperatorTypingStatus();
}
else if(nTextLen != 0 && nTextLen % 5 == 0)
{
bSend = false;
}
}
But its giving the error in the while loop of below code during run time as soon as i start typing anything in the editbox IDC_EDIT_OP.
#endif /* _SAFECRT_IMPL */
++p;
++p;
}
/* textlen now contains length in multibyte chars */
} else {
if (text.wz == NULL) /* NULL passed, use special string */
text.wz = __wnullstring;
bufferiswide = 1;
pwch = text.wz;
while (i-- && *pwch)
++pwch;
textlen = (int)(pwch - text.wz); /* in wchar_ts */
/* textlen now contains length in wide chars */
}
#else /* _UNICODE */
please help me.
Thanks In Advance.

Did you try debugging to see what happens ? And please, for the hundredth time, use the "code block" tag to submit code

Hi I am new to the MFC applications in vc++.
In my application I want to access the contents of second dialog box from the first,I created the object for the second dialog box and tried to access the values of the controls without saying domodal() but it is giving an error.
How can i handle this problem????????
Thanks in advance....

|
|
|

And the error is.........
BTW it's a good practice to have get/set methods implemented in your class to do this.
Somethings seem HARD to do, until we know how to do them.

i dont think its possible to get the values of the second dialog if the second dialog is not created. DoModal has to be called. otherwise u need to use a modaless dialog box.

We have one application written in MFC (dialog based). This application performs some admin activities such as loading Driver (.SYS file). This application helps in loading such drivers if user does not have admin credentials i.e. user is a normal user with limited credentials.
But the problem now is, if I am adding some more functionalities into it (e.g. one more function added to it) and compiled it, compilation become successfull but it is crashing at run-time. Following is the code that is written into it. I am not able to understand what it does because this is code is written by someone else. Please help me to understand this and also does this code creates problem during runtime.
Thanks

Those assembly lines just calls a function at the address 0402EE0h. Also it passes three parameters to that function.
The only problem I see is if the 0402EE0h doesnt point to starting of a valid function address. There is a possibility that the function address has changed since you have done some code modification. So find out the correct function adress and replace it in the assembly.
Since the function address is 0402EE0h now, I guess the function resides in the main exe itself. And I wonder why would some one call its own function in this manner...

Thanks for your reply. But I need to know how to compute this address. Pls let me know if there is any way of computing it.
Is the size of binary after adding any functionality creates any problem? However if I am deleting some function calls from code then there will be no crashing but program will crash as soon as I am adding a single function call. Pls suggest.

Undo all the changes in the code( I mean removing all the newly added functionality ). Debug the code and step in(F11) at the line "Call ECX". At this time if your code has debug information, debugger will display the name of the function at 0402EE0h.
After this, add the new functionalities, find the new address of the function and replace the address in assembly code. How ever if possible try to call this function in normal way. The same problem may again come in the future...
