I'd like to convert the C programs found in "Controling the world With Your PC" to Visual C++.Net programs. I have the dll for Win2000,XP and need sort of a starting point to the prodess. Ideas, tips? An exsample even ? Smile | :)

I did old QB & a little pascal. Got VB.Net and VC++.Net on the computer.

Thanks

Any C program should run in VC++, including VC++.NET. What problems are you having ? The most likely one is that a project you create will have precompiled headers turned on, and you'll need to turn them off, or create a stdafx.h file and include it everywhere.

Well, yes that sounds like that will be the next problem and answer. If I try to use (open project) from the start page, it only shows exstentions for the VB.Net that I have on the computer with the C++. It doesn't show C++ exstentions at all. If however I click on a file like duolphase.C , it will display it in visual studio but there are no controls avalable to edit the program. I mean no tabs, no controls at all.
I tryed to set options-environment but found nothing refering to the start page that made any difference. The only thing I can figure is I'll have to type it in as a new project and go from there. Like the header file thing you mentioned.
Wander what would happen if I rename xxxxxx.C to xxxxxx.cs ?? Smile | :)

Tryed posting in the VS forum but no answer as yet.

In case your wandering, yes there is a comercial app in the works and a gui-servo&stepper motor app for public domain.
Thanks for the help.

AAAhhh I got it! Use main menue not the open project tab.

File-open-openfile After it opens in the environment use start without debug . Using Start brings up an error message about it being an a bynary code it don't know. Then it will try to run, ( mixed results) but it does run.
Renaming the file didn't seem to make any difference. Soooo this means the next step is to type it into a new project so debug can handle it.

Small steps guys,small steps.

Gota keep reading this forum. Tons of info.

CImageList serialization under XP and NT

Heywood30-Mar-04 13:41

Heywood

30-Mar-04 13:41

I've recently updated one of my MFC applications to use the serialization functions available in CImageList (CImageList::Read and CImageList::Write).

The problem I'm having is, my application must run under both WinNT and WinXP.

When a file is saved under WinXP, the file is no longer readable under NT. I get an unexpected file format error, and the way the CImageLists are being saved seem to be the culprit.

Does anyone know what I can do to make the Image list serialization functions work the same under both operating systems?

When you save on XP you're getting a v6 format file, which is not readable by previous OSes. Use ImageList_WriteEx() and pass the ILP_DOWNLEVEL flag to save in a format that previous OSes can read.

WinXP : how to hide my console-app from the taskbar ?

Recap from the title :
I'd like to hide my console-based app from the windows taskbar.
(Basicly once executed, it should just run permanently in the background without bothering me with it's window Smile | :)

)

Anyone got any idea how to do this on WinXP ?
(I've searched for it but all I / Google could come up with was stuff that worked on Win9X... I'm proably looking in the wrong direction.. Frown | :(

I dont think you can do that by directly executing the console app.

You can do it by launching the console app from a windows app using createprocess and setting shownowindow* styel..

*I dont remember exactly the bit name but you can find out in the MSDN.

call GetConsoleWindow() to get the console window handle and then ShowWindow(SW_HIDE) to remove it from windows taskbar.

Close dialog box on loss of focus

Anonymous30-Mar-04 11:25

Environment: Windows 2000 Professional, VC++ 6

I am trying to trap the loss of focus on a dialog box in order to close it. Initially I thought that I could handle WM_KILLFOCUS or WM_ACTIVATE. Unfortunately these are not being fired as I expected.

My next approach used SetCapture to detect mouse down events outside the dialog. While it works well for that, it breaks the control notification messaging (e.g. BN_CLICKED): they are no longer fired.

Can anyone suggest a way around this or another approach? It seems like there should be a standard way to do this.

thanks,
Mike Thompson

I've tried it both ways. It started out modal but I made it modeless in the hope that I'd see WM_KILLFOCUS or WM_ACTIVATE at other times. No such luck.

I tried the following and it actually works:

void CDlgFocusTestDlg::OnActivate(UINT nState, CWnd* pWndOther, BOOL bMinimized) 
{
    if (nState == WA_INACTIVE)
        EndDialog(IDOK);
        // don't call base class' OnActivate
    else
        CDialog::OnActivate(nState, pWndOther, bMinimized);
}

Hope, this will solve ur prob

My problem with WM_ACTIVATE is that it is fired only when switching to another application. My application is full-screen and the dialog box is in a DLL loaded by the application. There is only our full-screen application to click on, so WM_ACTIVATE isn't fired.

SSL and 503 FTP Error :: Socket

valikac30-Mar-04 11:14

valikac

30-Mar-04 11:14

Hello.

I am working on a small socket application that utilizes SSL and FTP protocol.

The problem is that the server response with error:

"503 Log in with USER first."

The SSL is OpenSSL. Here is an overview of the sequence.

- winsock connect
- AUTH SSL
- SSL_connect()
- handshake is success

// At this point, everything is send/recv via SSL
// SSL_send() and SSL_recv()

- PBSZ 0
- PROT P
- USER <username>
- PASS <password>
...
// All the above are successful
// Server respond "230 <username> logged in."

// Every command afterward returns an error
- SYST

Basically, every command the program sends, the server would return "503 Log in with USER first."

Do you need to package outgoing data in a special SSL package before passing it to SSL_send()?

Please post if you have any idea.

Thanks,

Kuphryn
