How can i know that a certain path is valid???
In a browse button the user select a path and i want to know if it is a valid path.

i tried to use _access(char* path ,in mode) but i have a problem with it:
1) I don't know what the mode should be
2) When no path was selected (char* ="") the functoin return -1 meaning i's not valid and i don't want that.

Thanks

I use the Shell Lightweight Utility APIs for this kind of stuff. You need to include "Shlwapi.h" and build with "Shlwapi.lib". The API is very easy to use. For your question,

BOOL PathFileExists( LPCTSTR pszPath );

You can find this in MSDN->Platform SDK->User Interface Services->Windows Shell->
Shell Reference->Shell Lightweight Utility APIs

Hope this helps!

The other alternative is the API function GetFileAttributes(), which, despite it's name, works with directories as well. It returns -1 if the file/directory does not exist. So:

if (GetFileAttributes(path) == -1)
{
  AfxMessageBox(_T("Invalid Path!"));
}
else
{
  // Do stuff...
}

Hope this helps.

why CreateDirectory fails in NTFS drives ?

how to create Directory in NTFS Drives.

Try:

SECURITY_ATTRIBUTES security_attrib;
security_attrib.nLength = sizeof(SECURITY_ATTRIBUTES);
security_attrib.lpSecurityDescriptor = NULL;
security_attrib.bInheritHandle = TRUE;

CreateDirectory((const TCHAR *) A_strDir, &security_attrib);

If it fails, check @ERR or GetLastError() for information why it fails.

Re: Thanks now it is working very fine

Overlap two windows with different instances

8-Mar-02 19:13

Dear All,

I want to manage two different instances of the same application, that is
put one instance window always on top of another one. in another word, I
want to popup a window with different instance as a dialog box alike.

The communication of the two windows isn't a problem, I can solve it by
sending WM_COPYDATA to each other. What I want to solve is just 'z-order
position'.

Thanks! Smile | :)

Is it possible to make one (WITH DIFFERENT INSTANCE) as a child window of another?
If this can be done, which message or function should be used?
Does "SetParent(HWND, HWND)" work?

It will only work if you pass a handle to the parent window in when creating the child window. This causes Windows to set the parent window as the "owner" of the newly created window. Unfortunately, (AFAIK) this cannot be changed after the window is created. Belonging to separate processes shouldn't matter.

Hi I have a dialog based app which has a control with a CWebBrowser2 varible. My question is, how can I get the return number from the HTTP header (404, 500, etc)?

Thanks,

I thought about doing that, but its not predictible. For example, by default, IIS returns THe page cannot be found. Other webservers will return 404 in the titles, others won't. If I have to I can create a connection to the server and parse the returned header, but I was hoping that the return code could be easily found. Thanks anyway.

Just a quick question. I am just having a little problem. HOw would you accomplish this: you want to prompt the user with a message saying that the filename selected in a Save dialog is not supported by the application and you want the CFileDialog to stay on and allow the user to re-enter.

I want to have an option in my program which will let the user specify a folder for keeping the log files and some other files. The files would be used only by the progam which would be running as a service under the localsystem account. This folder should NOT be accessible (no read, no write, and nothing else) by ANYONE EXCEPT System and Administrator. How do I do this? Could someone give me an example code to explain things a bit? Or does anyone know of a project where this has been done? The target system would be NT/2000 servers. Any help or pointers would be greatly appreciated.

Thanks a lot Smile | :)

Just set the permissions on the folder to allow the access you want. This is done by a system admin, not code.

Good Luck,
