   Since no-one gave you a very clear answer or provided a solution...

   It looks like you are trying to use a Regular Expression to validate an email address. Neither the CString object nor the strcmp(...) function can perform Regular Expression operations.

   You need to find a RegEx engine to do that kind of comparision. boost[^] has one that you can use rather easily and it has good documentation and examples for its use.

   Lastly, note that certain characters may be valid in an email address, like #$&-+=!, so you might want to limit validation to something like making sure that it contains one "@" and at least one ".". Email addresses should be confirmed, not just verified.

   Peace!

how to solve the problem occured due to using setupapi.h and Dbt.h header files in my windows service application.. in windows XP and VC++.Net 2005

anumadhu21-Mar-07 21:32

hello,

I created a win32 project(precompiled headers, console application). This was created to create a service( for which i used SERVICE_TABLE_ENTRY, SERVICE_STATUS, SERVICE_STATUS_HANDLE, etc... required structures and methods).

Environment used:
Windows XP, VC++.Net2005.

Should work on:
I want to make this exe to run on windows 95,98, XP, 2000 and Vista.

my stdafx.h file contains:
#pragma once

#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers

#include <stdio.h>
#include <tchar.h>

// TODO: reference additional headers your program requires here

#pragma warning (disable:4430)//... i added this, since i was getting this error. and in msdn this //was given as its solution.

To this project, i have added two more files:
1) USBActivity.h
2) USBActivity.cpp

In USBActivity.cpp the hierarchy of headers included is as follows:
#include "stdafx.h"
#include <initguid.h>
#include "stdio.h"
#include <setupapi.h>
#include <dbt.h>
#include "afxcmn.h"
#include "cfgmgr32.h"
#include "Blowfish_Data_FileEncrpt.h"
#include "USBActivity.h"

The project properties are set as: Use windows Standard libraries, WIN32;_DEBUG;_CONSOLE as preprocessor definitions, Basic Run-TimeChks: Both (/RTC1, equiv. to /RTCsu) , RunTime-Library --> Multi-threaded Debug (/MTd), Use Precompiled Header (/Yu), Linker+AdditionalDependencies-->setupapi.lib.

I am getting following build errors:
Compiling...
stdafx.cpp

Generating Code...
DataSentinelService - 8 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I guess the error is because of :

--> calling a function in an SDK header file that is currently not supported in current build environment.

Could anybody help me out... in fixing this problem.
I have also seen the project given at the following link: http://www.codeproject.com/system/RemoveDriveByLetter.asp?df=100&forumid=294340&exp=0&select=1822184&tid=1815457#xx1822184xx

Here, it is given in vc++ 6. and when i compared the build environment everything was same.

In order to enumerate enumerate all the USB devices connected to PC, using a windows service... i have to use setupAPI in order to get setupDiGetDevClass etc methods.

I also tried with including windows.h file in stdafx.h. but it was also not helpful. since was included by-default. And on including it again i am getting the following error:

d:\microsoft visual studio 8\vc\atlmfc\include\afxv_w32.h(16) : fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>

Is there any other alternative?

Thanks

Choose, ignore html tags option, so that file included will be visible. Modify your post for that.
I feel its causing because of incorrect sequence of include headers.

yeah, probing towards the cause of this problem, i got two causes:

1) What you said that, the wrong order of include headers.

2) Accessing the SDK files from a application(my application) which does not support current build environment.

I am using VC++.Net2005 and Windows XP. I have tried lot many options of including the order of headers.. but none of them was much helpful.

And coming to not supporting build environment, i don understand how to get into its solution.

Do you have any clue or idea.

Thanks

   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 | :)

listview remove item problem

amitmistry_petlad 21-Mar-07 21:04

21-Mar-07 21:04

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.
