Although I've never tried, I believe sockets is what you'll need (e.g., recv(), send(), connect()). If, however, you are using MFC, take a look at CFtpConnection::OpenFile().

I don't think you can do that directly ...You can try CHttpFile class in MFC which will help you ...

I did this sort of thing recently using class CInternetSession. Have a look at that. (And don't forget that any \s in a string have to be \\ )

Anyone have any experience with changing an environment variable via the registry and then updating the system to recognize the change?
I have been able to successfully change the environment variable, but if I then open a command prompt it doesn't see the changes.
However if I then open up the System Properties, goto the environment variable section and open it up, click OK, then the desktop flickers, and the refresh occurs.
According to what I can find you're supposed to call
SendMessageTimeout( HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM)"Environment", SMTO_NORMAL, 1000 );
However this does not seem to work for me.
Anyone else deal with this, and if so how?
Thanks !

What does SendMessageTimeout() return? Have you tried increasing the uTimeout value?

I'm such a boner!
It turns out that the string values can't be string values !
They have to be expandign string values, i.e. REG_EXPAND_SZ! Once i changed that in the installer, everything worked fine!
I feel like such a friggin idiot

I'm glad you figured it out, because I would not have guessed that given your original post.

Well it turns out that was only part of problem.
The enrionment vars get expanded but they still don't seem to get refreshed.
I can run the installer, and open the System Properties and see hte new values correctly, but if I start a command prompt, and type the executable (whose path was added to the Users PATH env var) name, it just craps out and says it can't run the program. So apparently I still am doing something wrong

So at the command prompt, the PATH environment variable is correct, but the executable cannot be started. Is that right? If so, it appears that deeper issues are at play here.

hello!
I´m working with MFC. I´m making same threads where I execute a Query in a database. It use same CString, int and command variables.
It is an Example:
void STLogLatido::DoWork(void *pThreadContext)
{
_set_se_translator(SeTranslator);
try
{
CString id = GetParamID(2,msg);
//ejecutar comando
_bstr_t sql;
sql = "execute dbo.sp_latido @id_empleado=" + id;
pConn->Execute( sql ,NULL ,0);
}
catch (...)
{
}
delete this;
}
That work greate, but when the thread finish the memory process have been increased 4k.
Does anybody can help me?

Well.... I believed that when the thread was finished, It had to free all the memory which was used by the thread.
Am I wrong??

Yes, in a way. See the last section of this article for a better description than I can type.

Hi guys,
I'm working on my first MFC app and have hit a small issue with a palette window which needs to sit above the main view but all other dialog's should appear above it in the Z order. Currently the extended style is set to WS_EX_PALETTEWINDOW but this keeps the window on top of everything else. So even my File Open dialog disappears beneath it.
How can I specify this palette should always appear above the main window but below all else?
Thanks for any help,
Simon

The extended style WM_EX_TOPMOST (Part of WM_EX_PALETTEWINDOW) causes the palette window to be ALWAYS on top Z order, like stated in the Reference.
To overcome this problem, remove the style flag, and always when you create new dialogs or windows, or a window of your choice has focus, use SetWindowPos to place it's Z-order.
For example, when user opens your application, after the window objects are created but before they are shown, you place them with subsequent calls to SetWindowPos member methods to place their Z-orders in the way you please. Or, when your mainframe gets focus, you place the mainframe window under the palette window. Simple.
Again, when user clicks on the button to create the File Open dialog, then first position the windows, then create the dialog and make it modal to the application. This way it will always be on top of your app.
The key is to reposition the windows always when something, which would change the window display order, happens (Like gaining/losing focus, modal messageboxes/dialogs etc)

Sorry to bother you again but I'm still tearing my hair out with this palette window problem. I've added a handler in the MainFrame class to pick up MoveWindow notifications. This works okay. It gets a pointer to the View class and calls the UpdatePalettePos function.
Inside the UpdatePalettePos function I try to use SetWindowPos to move the palette and bring it back on top of the mainframe. However, the minute I try to access anything within the palette object the application bombs. Even m_dlgPropertySheet->GetWindowRect(rPropsRect); causes a crash. Yet the exact same function is called elsewhere within the View class and works fine.
Ahhhhhhh!
Please help!?

Run the debugger, setting a breakpoint before the call to UpdatePalettePos. Enter this call, and see where your application crashes. Now, debug again, this time paying attention to different variables and pointers, if they point to correct locations (For example, the m_ptrPalette in CMainFrame must match with 'this' in CPaletteWnd).
After you have specified the position of the crash, take note of the error it gives you. Is it an assertion error ? An access violation ? What is the error message with the crash ? Note that you won't see these error messages unless you use the debugger.
With this information, post the error code, and a exerpt from the code flow. Post the point where you call UpdatePalettePos and the declaration of this function.
