I am trying to install a "WebDisk" from my website host and I get the following error message from Internet Explorer "The web folder is not available. Please insure that the port is not firewalled." The port IS NOT firewalled yet I continue to get this error message. I tried to manually create the web disk folder and I get the same thing. Without the web disk folder I cannot upload files for my website. Any suggestions?

error C2597: illegal reference to non-static member 'Test::sayHello'<br />
error C3867: 'Test::sayHello': function call missing argument list; use '&Test::sayHello' to create a pointer to member<br />
error C2568: '->*' : unable to resolve function overload<br />
If you have any ideas plz tell me
Thanks in advance
A static function can be called without creating an instance of the class. But the member function pointer needs the class instance to call the function. So, the compiler doesn't allow calling a non-static member function from a static function.
You can't access instance members from a static method. Also the singleton implementation is wrong and your example doesn't make sense at all. Here is a modified version of your code which compiles fine.
I am new to the windows 32 api and i am trying to use the win 3 api function CreateProcess.
I am simply trying to use this function to open the msn messanger process on my windows 7 pc, but i keep on getting a 0 exit code(failure). this is my code:
// Start the child process.
if( !CreateProcess( "c:\Program Files\Windows Live\Messenger\msnmsgr.exe", // module name (use command line)
NULL, // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // No creation flags
NULL, // Use parent's environment block
NULL, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi ) // Pointer to PROCESS_INFORMATION structure
printf( "CreateProcess failed (%d).\n", GetLastError() );
// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
the path c:\Program Files\Windows Live\Messenger\msnmsgr.exe is my msn messanger directory, but somehow i can get it to work.
1) try running [c:\Program Files\Windows Live\Messenger\msnmsgr.exe] from the command line from a dos/cmd prompt, see if that starts on its own, and/or double click it in explorer - hopefully this step will prove that its the right exe and doesnt need any parameters
2) I think the use of your module and command line args are slightly incorrect - I would repeat the [c:\Program Files\Windows Live\Messenger\msnmsgr.exe] in the commandline parameter of the createprocess api, so in effect the module name == the command line IN THIS CASE instead of the NULL you specified - if there were startup options [for example /s para-whatever] you would then end up with
I checked your code against mine and see the following differences:
- Creation flags. I use: normal_priority_class+CREATE_NEW_PROCESS_GROUP
- I use CreateProcess(NULL,"C:\Program files....". Thus turn the first 2 arguments.
- Try parent starting directory "c:\Program Files\Windows Live\Messenger". Or try to run something in the windows folder. Guess that the folder is not accessable. As mentioned try to run
it manually from the commandline.
- Set si.wShowWindow to SW_SHOWNORMAL
Follow the suggestions by Garth J Lancaster and Chuck O'Toole.
In addition to those suggestions you also need to pass the command line in a modifiable array for the unicode version of CreateProcess.
Here is an excerpt from the documentation - The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter is a constant string, the function may cause an access violation.

I'll explain what I am trying to do with my project. I have created a client for a 3D world but when you click on the application the game launches but what I want is when you click on the application a login window appears so users can login to the project or create a new account with a new window.
Visual Studio can create a skeleton dialog-based application for you, either a MFC project or a Win32 one(if you use MFC the task is somewhat simpler). As for connecting to the database, you've a lot of options (personally, I like ADO), have a look at CodeProject's articles about [^].
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

As a matter of fact, I did. That's why I made the comment. Hard to tell if he's being tounge in cheek or just seriously out of touch. For going to Europe's largest school, I would have hoped their English department was doing a better job.
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.
Okay, fair point. Any chance I could have that "duffer" back - think I may need to assume that role for a little while.
Personally, I was left with the impression that it was a rather cheeky and informal tone on the site, though as you mention the spelling and grammar don't exactly put him in the queue for Pulitzer Prize winners. (not that I'll ever get one mind you)
