Can´t implement CInternetSession The_Pike21-Mar-02 5:11 The_Pike 21-Mar-02 5:11  Hi! I´m trying to create a simple ftp client but I´m having problems creating an instance of the CInternetSession class. I´ve downloaded an example ftp client that works but I just can´t get my own to work. Do I have to link the CInternetSession class in a certain way? I´m using VC++ 6 SP5. /Jii Re: Can´t implement CInternetSession dazinith21-Mar-02 5:29 dazinith 21-Mar-02 5:29  Here is some code i wrote: void CTransmitView::TransmitReports(CString ftpserver, CString user, CString pass) { CInternetSession mySession; CFtpConnection* pFtpConn = mySession.GetFtpConnection(ftpserver, user, pass); if (pFtpConn) { pFtpConn->SetCurrentDirectory("\\uploads\\"); pFtpConn->PutFile("test.txt", "test.txt"); pFtpConn->Close(); } ---- there is no exception handling in there.. you should add some for CInternetException and some other stuff prolly.. -dz Re: Can´t implement CInternetSession Carlos Antollini21-Mar-02 5:41 Carlos Antollini 21-Mar-02 5:41  You are using a Direct Connection or a Proxy? You are trying to connect using any Port? Show any of your code... Best Regards.... Carlos Antollini.

This has to be done by the main dialog on a signal received from a working thread. I've tried sending an user message and by directly calling a method of the main dialog class; the result was runtime error on release configuration, so i need a better way to communicate between the worker and the main dialog. I'm waiting for a clue. rechi Re: Creating modeless dialog failure Joaquín M López Muñoz21-Mar-02 4:29 Joaquín M López Muñoz 21-Mar-02 4:29  Could you post some code to see how you've implemented the thing? In principle, sending a message from a worker thread to a dialog to perform some UI operation is OK, so I guess there's hope your approach will work Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Creating modeless dialog failure Hans Ruck21-Mar-02 4:44 Hans Ruck 21-Mar-02 4:44  There is nothing special in the code; in fact is really classical: (in the thread) ((CDialog *)GetOutput())->SendMessage(WM_VIRTUAL_WANTCHAT); (in the dialog message map) ON_MESSAGE(WM_VIRTUAL_WANTCHAT, OnVirtualWantChat) (the method) void CClientxDlg::OnVirtualWantChat() { CChatDlg *dlg=new CChatDlg(); dlg->Create(IDD_DIALOG_CHAT, this); if (dlg) dlg->ShowWindow(SW_SHOW); } rechi Re: Creating modeless dialog failure Joaquín M López Muñoz21-Mar-02 5:02 Joaquín M López Muñoz 21-Mar-02 5:02  What does GetOutput exactly do? Is the CClientxDlg blocked in any way as in your previous questions from yesterday? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Creating modeless dialog failure Hans Ruck21-Mar-02 5:15 Hans Ruck 21-Mar-02 5:15  GetOutput returns the pointer to the main dialog window object (CClientxDlg *) and the window is - 100% sure - not blocked. The facts are: i read a group chat request from a socket in the worker and i have to order the main dialog to create the chatting modeless dialog. I also have to say that i'm not sure of the problem's origin so, if you find out that it's not this one, i should not be surprised. rechi Re: Creating modeless dialog failure Hans Ruck21-Mar-02 6:02 Hans Ruck 21-Mar-02 6:02  I've created a test application with a worker that sends commands (WM_USER+1) once in 3 seconds for the main to create modelesses. It works the first time and fails the second. Despite this, it's perfect on debuggin' configuration. So, this remains the problem! rechi Re: Creating modeless dialog failure Joaquín M López Muñoz21-Mar-02 8:00 Joaquín M López Muñoz 21-Mar-02 8:00  Ummm... I think your user-message handler does not have the right signature. Try declaring (and defining) it like this: afx_msg LRESULT OnVirtualWantChat(WPARAM wParam, LPARAM lParam); And don't forget to tell us back the result Good luck.

Thanks. remote shutdown 21-Mar-02 0:45 21-Mar-02 0:45  how to implement remote shutdown in Windows NT ?? Re: remote shutdown Jon Hulatt21-Mar-02 2:29 Jon Hulatt 21-Mar-02 2:29  There's a utility to do this in the Windows NT resource kit. Sorry to dissapoint you all with my lack of a witty or poignant signature. Re: remote shutdown Joaquín M López Muñoz21-Mar-02 2:24 Joaquín M López Muñoz 21-Mar-02 2:24  There's a program called shutdown.exe for doing this, available in the Windows NT resource kit. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: remote shutdown pba_21-Mar-02 4:26 pba_ 21-Mar-02 4:26  Or you can use InitiateSystemShutdown/InitiateSystemShutdownEx. Re: remote shutdown Andres Manggini21-Mar-02 7:31 Andres Manggini 21-Mar-02 7:31  Yes, this one works pretty nicely. Andres Manggini. Buenos Aires - Argentina. Simple Drawing Daniel_Pollard21-Mar-02 0:43 Daniel_Pollard 21-Mar-02 0:43  Please excuse if this has been asked before, but i have a handler for when the user clicks on a menu item, this is the code that i have: void CTestApp::OnTestMenu() { CWnd* pWind; pWind = theApp.GetMainWnd(); CClientDC dc(pWind); dc.TextOut(200,200, "Hello World"); } This works fine, but it doesn't repaint the screen if it gets covered. I guess what my question is, do i need to create a Global Device Context that i write to from different parts of my app and then paint this to the screen in my OnDraw() ? Thanks Re: Simple Drawing Tomasz Sowinski21-Mar-02 0:54 Tomasz Sowinski 21-Mar-02 0:54  In Windows you need to implement your drawing code in handler of WM_PAINT message. In MFC this will be OnDraw if you're CView-derived class or OnPaint otherwise. Tomasz Sowinski -- http://www.shooltz.com LPUNKNOWN not marshaling ok... Braulio Dez20-Mar-02 23:50 Braulio Dez 20-Mar-02 23:50  Hi, I have a DLL, that I called from a different proccess space ( I run it in an automated instance of word, and I get control to it from my application). I pass an LPUNKNOWN pointer to pass one stream with one metafile, the problem comes when I try the DLL in a computer where I haven´t build the project with Visual Studio, then my dll crashes when passing that parameter. How can I fix that ? ( is there some extra file or registry thing, instead of LPUNKNOWN maybe LPIDISPATCH ?, or merging proxy stub ? ( how to do this manually...) ? Thanks, Bye ! Braulio Re: LPUNKNOWN not marshaling ok... Joao Vaz21-Mar-02 0:16 Joao Vaz 21-Mar-02 0:16  Braulio, explain better your problem ... You are using two computers, eg. try to call the dll from another computer ? You registered properly the dll ? Merging the proxy/ stub normally isn't necessary if you are using type library ,marshaling, I presume you are, because you are using automation, and using automation requires automation compatible parameters , eg . passing IDispatch pointers to world ... Joao Vaz Re: LPUNKNOWN not marshaling ok... Braulio Dez21-Mar-02 0:24 Braulio Dez 21-Mar-02 0:24  Hi Joao !, Nice to meet you again ! I´m still working on the Ms Word thing... ( I have my ATL ActiveX control in a DLL, then Ms Word automated, and my MFC application that controls that Ms Word app). I've a method defined in an interface to pass the Metafile to the ActiveX, that method has as a parameter an LPUNKNOWN ( later I make a QI to IStream), should I pass IDisptach pointers instead of IUnknown ?. The problem that I have is that the call to this method only works in the computers where I have compiled the DLL. If not, when I call the method it fails ( just crashes, or gives me a message saying that something is going wrong). I register the DLL calling this "regsvr32 MyDll.dll", did I missed any parameter ?. My idea was to generate the Proxy/Stub DLL ( merged in my DLL), to call the methods, is that a good idea ? Thanks a lot Joao, Bye ! Braulio Re: LPUNKNOWN not marshaling ok... Braulio Dez21-Mar-02 0:57 Braulio Dez 21-Mar-02 0:57  Just one stupid question... I don´t need to copy or register the TLB of my DLL isn´t it ? ( is only to build the object that uses it isn´t it ?). Where can I find a list of automation compatible parameters ? Thanks, greetings Braulio Re: LPUNKNOWN not marshaling ok... pba_21-Mar-02 4:41 pba_ 21-Mar-02 4:41  The automation marshaler works with VARIANT compatible types ( VT_BSTR, VT_I4, etc). If you want to make cross-apartment calls in your app you can use the automation marshaler or generate and register a proxy/stub for your interfaces ( don't pass pointers to interfaces from one apt. to another, use CoMarshalInterface / CoUnmarshalInterface ). Do you have any COM related messages when your app crashes, or just an access violation exception ? Re: LPUNKNOWN not marshaling ok... Braulio Dez21-Mar-02 23:03 Braulio Dez 21-Mar-02 23:03  Hi ! Well, what I did was to pass and IStream interface pointer to the ActiveX, I passed it as LPUNKNOWN pointer. Should I use CoMarshalInterface/Co... ( how can I use that ?). The funny thing is that in the machine where I compile the source it works but in others machines not About crash, in XP sometimes crashes sometimes gives a message saying that the font is too big ( the stream contains a metafile), in Me it says that there was inconsistence or the operation cannot be done ( something like that). What I have is: MyApp |---> Word Automated --> My DLL| What can I do ? , Thanks a lot Bye ! Braulio
