   What offset are you talking about?

   Offsets of different sections in the PE format? You have to read the PE header (and knowing the PE format helps).

   Default address/offset of loading into memory?

   Offset of where the good code ends and the bad code begins? Smile | :)

Peace!

You don't need a library (you can write your own) if you know the WAV file format and the MP3
format/compression. Google may help Smile | :)

listview remove item problem

Well I have almost done the remove item from the list but the problem is that one item is rest each time in the listview when I clicked to “clearcomplete”.

In detail,
I add my files from the add button and select that file and proceed to protect, before protection the file shown the status “incomplete” but when the file protected
I had change the status to “complete” in the particular column. When a bundle of “complete” files seen in the list the user can remove it from the listview for that I have write the code
On WM_COMMAND providing one for loop , iterate up to count in each count checking out whether the column having “complete” then remove it, but when I fetch the status it shown me each time “complete” incase of when counter(i) contain the status “incomplete”.

Please check the code is it ok ?

case IDC_CLR_COMPLETED: 
                        {
                              if(lParam==-1)
                              {                             
                                    EnableWindow(hDlg,FALSE);
                              }
                              else
                              {
                        int count=ListView_GetItemCount(hList);                           
                        TCHAR buff[MAX_PATH]={0};
                                    for(int i=0;i<count;i++)
                                    {                       
                                                
                  ListView_GetItemText(hList,i,9,(LPWSTR)&buff,MAX_PATH);// I found the fault here might be the buff not cleared every time so its display "complete" every time incase of when item having "incomplet". 
                                                std::wstring buff_input(buff);      
                                                std::string compare(buff_input.begin(),buff_input.end());                     
                                                if(compare=="complete")
                                                {
                                                 ListView_DeleteItem(hList,i);
      
                                                }                             
                                    }
                                }
                        }
                      break;

2) how can I call Wndproc again once I logout? Do I need to make any service for that? In my application there is login/logout funda.
Help ! me please!

Thanks & regards

First of all change your for loop logic, just reverse the loop like

for (int nIndex = nItemCount; nIndex >= 0; nIdex--)

This will solve one logical problem.

Instead of checking like this, use any of the string comparing API..

The operator== is part of std::string. Why would you suggest using some other function?

I'm seeing immediate problem in above code. You are getting item count from list box. And used it in for loop for deleting items.
But with each deletion, this count should be decreased, where as you are refering to same old count.

Yes, you need to write windows service for this. You would get lots of good articles on CP for this.

I added one edit control in my dialog. I restricted to number only. It is a normal edit box. In properties I made it to number only. In normal key press event user can not enter other than numbers. But when i given to tester, he is trying to copying the data from else where and pasteing in this edit box. Big Grin | :-D

Any simple way to restrict this copy and paste one. (Other than creating our own deriving CCustomEdit). any clues friends... Smile | :)

You can try EN_CHANGE or EN_UPDATE to validate the text in the control

You cannot use strcmp like this..
the string given inside the quotes will be taken as such, i.e., strcmp has no intelligence to interpret your logic Smile | :)

here.

Better you can find different parts of email and check it for unacceptable chars in it.

Many string functions are available, say strchr or CString::Find(..),..
