Yes.

It is ok, as long as the calling application doesn't have to free or delete the memory.

Yes, even I am blogging now!

Thanks Daniel. The calling app would have to free the memory, so I think what I'll do instead is have the method take a 2nd LPSTR parameter which will be the output. That way I can feed in a StringBuilder and have it work without issue.

Will an event be raised when all the controls in a form has been drawn?
I have a form with many buttons with BGpics in it. Can I set the form to invisible, let it load all the pic, and then show it instead of it showing it and loading the pic at the same time (this makes it look really laggy)

If a control is not visible, and its background image is changed, will the image actually change? or will it only change only when it becomes visible?
|
|
|
|

That depends on how you specify "the image".
If the control is not visible, there is no background image drawn. If you change the property for the background image, the property changes, but as the property is not used as an image, the image can't change.

If the control is not rendered, then no image is drawn.

Yes it will. But you won't see the change until you make the control visible.

That means that if I have a number of pictures changed but not visible, it has potential to slow down the foreground performance right?
|

Yes, your app will take a performance hit every time you change (i.e. read) a new image (assuming you're reading them from a file).
A simple work-around would be to only remember the new image name everytime you "change" it. Then, when the control shows itself, it should load the current image (if it hasn't already done so) and set it as its background.

How would I go about creating my own file format for an application?
Any help is appreciated

Come up with three letters that are not commonly used ( not .doc for example ), then write the code to store relevant data to a file, and read it again.

Like Christian said, pick an uncommon extension, and use any file reading and writing mechanisms you want. For maximum efficiency, pick a file type that has lots of existing library support (like Xml or MDB), and use that file type with an uncommon extension.
Your files look like "ABC" files in explorer, but your app knows that they're really XML or Access database files when it goes to read and write them.
Share and enjoy.

Hi
I'm use using HttpWebRequest and HttpWebResponse to get a big xml file (about 10mb) from the web.
Now I want to parse this file and store it to the hard drive at the same time.
Problem:
When I store it first, then load it via TextReader it takes to long.
When I parse it directly via XmlTextReader, I can't save it to the hard drive any more.
Any idea, how to manage this problem? Properbly by filling an memoryStream?
Thanks
Paul

use the XmlTextReader, and as you parse the file, use a XmlTextWriter to save it on disk.

Hi
i had a problem with connecting to my Data Base on the server but after giving my user the permissions it works.
Now i have a problem, when i doing an SQL Query on the table(select * from Users) i get the answer with the Query Analyzer.
when i am writing it in the source code with C# i get this error message:
"SELECT permission denied on object 'Users', database 'RTQ', owner 'dbo'. "
the exeption comes from this function:
myDataAdapter.Fill(myDataSet,"Users");
the hole code is :
mycon = new SqlConnection("Data Source=localhost;Database=RTQ;Integrated Security=SSPI");
mycon.Open();
myDataAdapter = new SqlDataAdapter("select * from Users",mycon);
myDataSet = new DataSet();
myDataAdapter.Fill(myDataSet,"Users");
mycon.Close();
Why is that????
Thanks you all

Does the user have SELECT permissions?
|
|
|
|

How do i konw this?
i gave him the login permissions, i thought that all the permissions come with that.
Do i have to give pemissions for each SQL command??
where do i do this?

Te easiest way is to make the user database owner. That includes permission to do anything.

That's an easy solution, but lets not open a security hole too wide.

You are right of course. On a distributed application the premissions should ideally be minimal, for an example only permission to execute stored procedures.
In a development environment (as I got the impression we are dealing with here) security is normally less of an issue, and granting database owner access can be an acceptable way to make it work and save permission hassles for a later stage.

Ah yes... the later stage when time is tighter and the client is moaning about when they will get their application and all of a sudden it is discovered that the software is relying on some security setting being left open when really it should be shut.
I know what you mean though. It is very tempting just to open everything to make development easier (not just databases but for any secured system), but in my experience it just causes more problems later on - especially if it is in an area where I don't have much experience already and I don't know how to properly develop the app bearing in mind the security has to lock down later on. In cases where I should really know better, I always manage to forget some little thing that causes lots of problems later.

Well, that's not really the stage I had in mind. The thread writer seems to be in the stage of getting a database connection to work at all, and at that stage it's difficult to be concerned with security issues.

Login permission is just that: Permission to login. It does not grant any other rights.
You need to add the user associated with the login to the database you wish to access.
Then you need to <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_ga-gz_8odw.asp" rel="nofollow">GRANT</a>[<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_ga-gz_8odw.asp" target="_blank" rel="nofollow" title="New Window">^</a>] the user the rights to do what is needed. Normally, I just permit access to stored procedures. That way all the application can do is what is defined in the stored procedures.
