my question :
i making a ftp client with socket api,but a with it.i can't do it
who can help me and see my code a part . thank you.
bool CCftpdemoDlg::Getftpserverdir()
{
SOCKET m_datsocketsvr;//数据连接socket
SOCKET m_datsocketclient;//ftp server 的数据客户socket
SOCKADDR_IN hostaddr;
//向ftp server发送命令"TYPE I"
//数据格式命令
if (!SendCommandtoftpsvr("TYPE I\r\n"))
return false;
//创建监听的socket等待ftp server 反向连接
m_datsocketsvr=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if (m_datsocketsvr==SOCKET_ERROR)
{
CString szerr;
szerr.Format("socket()error!\t%d",WSAGetLastError());
AfxMessageBox(szerr);
return false;
}
hostaddr.sin_family=AF_INET;
hostaddr.sin_addr.S_un.S_addr=INADDR_ANY;
// hostaddr.sin_port=htons(5002);

if (listen(m_datsocketsvr,5)==SOCKET_ERROR)
{
CString szerr;
szerr.Format("listen()error!\t%d\n",WSAGetLastError());
AfxMessageBox(szerr);
return false;
}
//得到本地ip和断口
CString szip=changeip("192.168.122.15");//*****注意:这个ip一定是本地的ip，让ftp server连接你
UINT nport;
CString szipx;//暂时先用不上这个ip
Gethostipport(m_datsocketsvr,szipx,nport);
// 现在还不明白这句是什么意思,将ip和断口号与256的计算结果
// 连接起来,然后做为PORT命令的参数，发送给ftp server
szip.Format(szip+",%d,%d\r\n",nport / 256,nport % 256);
if (!SendCommandtoftpsvr("PORT "+szip))
return false;
//发送LIST的命令向ftp server
// 并且接收ftp server的回应
if (!Sendcommand("LIST "))
return false;
if(!Rev())
return false;
// AfxMessageBox("sDSDs");
//如果以上都通过了，ftp server 开始连接本地的正在监听的socket
// 用来传输数据,
// 以下是接受ftp server 的连接请求，并接收数据

using WH_CBT hook may get some information when a windows' status changed such as creating/destorying/size and etc.
Some windows created may be dialog form , and some of them might be Information_style_dialog, some are warning_style_dialog through their icon style.
So , which info from lParam or wParam can help judge dialog's style while using WH_CBT hook ?

I think these "styles" only apply to the MessageBox() function, in which case, the "style" is not stored anywhere. It is created at runtime.
If some dialog is using similar icons, there may be no way of finding out, short of parsing the dialog box template, or the dialogbox instance itself.

Then , if the dialog is created by MessageBox() function, there is still no way to find out its icon style ?
if the applcation turn out an exception, can Hook help recognise the error just happened ?

Short answer: NO

Ok,
I am making a program for a friend that travels alot and has several internet connections around the world. Therefore he would like a dial up application that logs time on each different connection and all the details.
Now i can dial and hung up with no problem but once I have dialed I don't know what to do next. I seem to receive alot but internet explorer doesnt find any pages nor can i connect to something directly with the ip.
Could someone please point out the steps invovled in successfully connecting to the internet with a third party software package. Thank you.

So you have created a dialup connection using RasDial()? Is the Ras Entry you used connecting to an actual ISP?

yes, I'm testing it on Wanadoo Spain dial up service.

So when you use the Windows dialer with that entry everything works fine but when you use your application and RasDial() with that entry it does not work?
That is bizarre. I would not have a clue what would cause that.

generate key pair, signature a text file, no hash, then write to a listens file which can be complete revert to the text file. revert fuction also needs.

Ok, i know how to set the value of keys in the registry, but im not quite sure how to set the defualt key's value, is there some special way you have to go about? an example would be nice.
thanks in advance.

Pass a '0' or a NULL-String ("") i.e. two double quotes with nothing in between, to the RegSetValueEx()'s lpValueName parameter.
The hKey value should be an open key or one of the "default" root keys such as HKEY_CLASSES_ROOT, HKEY_CURRENT_USER etc.

here take a small example:-
you have to give the value to defualt value of Archer key presents in following path.
HKEY_CURRENT_USER\Software\Archer
Now Here is Code:-
CRegKet a;
a.open(HKEY_CURRENT_USER,"Software\\Archer");
a.SetValue("Archer","");
a.Close();
this will do it for you.

Hello there!
Again I have a question for those of you out there... And this time it is all about 5 windows (modeless dialog boxes) I have being displayed at a certain point in time in my SDI MFC app. It happens that these 5 windows, which are created with a CFrameWnd as their parent (the main window), lose their focus, meaning they become inactive => therefore the thread subject).
That mustn't happen at all costs as it just hasn't got any logic -- not from the User Interface point of view anyway.
What I was expecting to create was five dialog boxes which look active whether they have the focus or not.
What I need, basically, is five windows, which look like toolboxes, that must look active independently of whether they have the focus or not.
Can someone please point me in the right direction? All comments/suggestions are more than welcome.
Thank you very much.
David
PS: By the way, these modeless dialog boxes have the "toolbox" style.

I'm sure there's a better solution than what I'm proposing: do custom painting of the caption bar (see this[^] article) and always execute the "is active" case.

Hey! Thanks for the reply!
I was actually considering that option, but I kept on thinking that a different approach could be pursued... I guess there isn't...
Can I just ask you something? Do you know any links that teach how to paint the title bar of Windows XP controls?
Thanks Rav!
David

Not sure what you mean by a title bar of a control. In general, you can customize a control's appearance by overriding DrawItem(). This method is passed a pointer to a DRAWITEMSTRUCT that defines the drawing operation to be performed.

Ah. Override CWnd::OnNcActivate() and return 0. This will prevent the window from appearing inactive. See this[^] MSDN link.

I was trying that Ravi... but I don't know why it doesn't seem to work with my dialog boxes. Could that have anything to do with the fact that the events aren't being fired?
|

Besides writing the handler, you need to have a message map entry that will cause your handler to be invoked. Is that what you meant?

No, I mean, the event handler is invoked and executed -- no problem with that whatsoever.
The problem is that because the dialog box is being kept active, the main frame window and the other dialog boxes don't receive any message notifications...
I wonder why?
David
PS: Could this be a dialog box-only issue?

Ah (again). I think a better way would be to just override WM_NCPAINT and always render the caption bar as active. This will allow the modeless dialog to become inactive when necessary, but it will appear active to the user.

And how do I do about rendering the caption bar (independently of the Windows OS version installed) ? I mean, is there a way of calling a API method to do that?
