Hi bob,

Thanks for the reply,

Yes both the computers on same domain, How do i make sure that that machine which is running service is given explicit rights to the file share and the folder? And do you mean the computer name by resolvable name?

Yes the computer name is what I meant. I just wasn't sure if an alias is allowed so I worded it carefully.

In regards to setting up rights, on the machine that is sharing the resource, you would normally right click on the folder you are sharing and on the "Sharing" and "Security" property pages, you would give the "Computer" that the service will be running on appropriate rights to the resource.

Local System acts as the computer on the network.

Be advised...there are some security implications to consider here but I'm guessing you've already weighed the risks.

Hello bob,

Yes i gave all the rights to computer but still access denied is coming, Let me explain the scenario again, The service is running on windows XP, The file is in windows server 2003, both are on same domain, By right clicking and sharing security of shared folder i gave all the possible rights to XP machine, But whenever the service(on XP) tries to copy it gives me access denied.. Am i missing any more setting here?

Thanks

You might try rebooting both machines, just to make sure but I don't recall anything else being necessary.

Choosing files from a directory

Hi all. I have a console application, running under Windows, that asks for a folder or directory and includes those files it supports and leave the rest. The following code is part of the definition of the function that does it:

....
....

char filePath[280] = {0};

....
....

strcat(filePath, "*.mp3");

....
....

The application searches the folder for files to add. The above code works when FindFirstFile() is called. But I want a way through which other file extensions (e.g. .wav., .wma, etc) can be included so that files with these other file extensions will be returned. I did something as follows, which I only guessed as I did not know how to do it, and it did not work:

strcat(filePath, "*.mp3;*.wav;*.wma");

When FindFirstFile() is called, it returns INVALID_HANDLE_VALUE;
I need help on how to solve this problem. Thanks.

There is no immediate support for what you want. The FindFirstFile API takes a single API, much like Windows Explorer lets you search for one thing at a time. The filter may contain wildcards, but does not support alternatives.

The obvious solution to such limitation is to have a loop, that iterates over your alternatives; so it would search all *.wav, then all *.wma, then... However it is up to you to add such loop.

There is one alternative that may or may not suit your app: you could relax the filter so all required files match, possibly yielding false positives, which you then have to skip by adding some tests. That could boil down to searching for *.*, then checking the extension is one of some. The disadvantage is you get a lot of matches; the advantage is the filesystem is searched only once.

I have used *.* but when I call FindFirstFile() for the first time, it returns the character '.', when it is called the second time, it returns '..', then subsequent calls return the files in the directory. Is there a way to prevent what the function returns for the first two calls? Then I will use a loop to check the file extensions.

AFAIK . and .. represent the current folder and the parent folder; if you get them (even when they don't really match your filter), AFAIK there is nothing you can do except test for them afterwards. The behavior of FindFirstFile may depend on your operating system and your file system. I tend to code defensively, and not to rely on observed behavior.

In a way to get rid of the '.' and "..", I have added the following code:

while (findData.cFileName[0] == '.' || findData.cFileName == "..")
{
    FindNextFile(handle, &findData);
}

Although it's working, I don't know if it is efficient to do it like this. The loop is executed after FindFirstFile() has been called and its return value checked not to be INVALID_HANDLE_VALUE. When the loop breaks, the &findData has its member cFileName pointing to one of the files in the directory.

That sounds OK. You could create your own MyFindFirst() function that contains the original FindFirst call and your skip-loop, hiding all of it from the user.

You could also just check the attributes of the returned item in your findData structure and ignore entries with FILE_ATTRIBUTE_DIRECTORY set.

Also

while (findData.cFileName[0] == '.' || findData.cFileName == "..")

The second test will never pass, you cannot do a string compare in this way.

It's time for a new signature.

It is also redundant since the first test catches that condition also.

And catches any file or directory whose name starts with '.'.

What you have so far looks good enough.

There is an API called SHFileOperation that can take multiple wild cards.
But you cannot use this to find files.
You have to either copy or move or rename or delete the files.

I'm not sure what exactly your application does but if you can copy the files to a another folder or temp folder, this API may be helpful.

How to move buttons to the left side？

How to move windows titlebar (included buttons: Close & Minimize & Hide) to the left side ?

What I want to do is to move buttons to the DockablePane left side. I've created a derived class of CDockablePane.

Thanks,

One way could be to handle WM_NCPAINT[^] and WM_NCHITTEST[^] and draw and handle hit testing yourself (possibly using the themed drawing methods like DrawThemeEdge[^] and such for the drawing).

How to tile multiple windows in a single view

I need better control of multiple windows opened in one MFC document / view.
Ideally I would like to be able to tile / cascade / select these windows in similar fashion as MFC main frame does. Anybody can point me to article / source code for such task?
I am not looking for multiple views connected to same document.
Any constructive help is as always appreciated.
Thank you for reading.
Vaclav

Are the views in the same frame window? If so, then you can use the MDICascade( ) method like standard MFC.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
