You haven't been able to find any articles on the internet on saving data to a database using C#? You can't have been looking very hard then.
You haven't said what database system you are using. If it is SQL Server, a Google search will throw up plenty of examples.
No one is going to write your code for you. You should research the problem and write it yourself.

Hi guys,
I'm developing a C# Windows application which makes a HTTP POST for uploading a file from the local system to the remote web server. I need to show the progress of uploading (ie. No of bytes uploaded and time remaining) in a progress bar of the Windows application. Can you guys please help me how to get the progress information of the HTTP POST.
Thanks in advance.

Usually this is achieved by sending a predetermined number of bytes at a time in chunks and reported back to the user how many of the bytes have been sent and how long it has taken the whole operation to execute.

So, do you mean to say that I must send segments of predefined number of bytes and I've to reassemble the segments at the remote server? Any other alternatives? Does the .NET HTTP Request class contain any parameter to report the number of bytes sent or is there any event triggered to report the same?

I have not seen anything that tells you how many bytes have been sent. The solution I have mentioned is the only one I know of. Maybe someone else will come along with other ideas.

Hi all,
I am currently involved in a school assignment in which I have to use DrScheme together with C#. I know how to invoke a Scheme function from C# via calls through the MysterX library. The library also allows events to invoke on COM classes and components, but the only example I can find are Microsoft-defined COM classes, like ADOConnection.
Is it possible for DrScheme, via MysterX, to invoke a C# program's methods? (Is a C# program considered a COM class?) I have hunted high and low everywhere but couldn't find an example at all.
Note: It's not a requirement of the assignment to do this; it's just that our group, for some added functionality, wants to use Scheme for scripting, much like Scheme for GIMP, but the documentation is really sparse and there are no examples. If I can just get one example of calling a method in a C# program from Scheme with MysterX then I believe I can figure out the rest myself
Thanks in advance!

Not sure, I've never worked with DrScheme. Have you asked your teacher?

I'm using Visual Studio 2005 and have a Form with a MaskedTextBox.
In the Property Grid, i set AsciiOnly to true. All other properties
are unchanged. Despite that, when I run the program, the MaskedTextBox
still accepts numerals and commas, etc... To my knoledge when the AsciiOnly
is set to true, the MaskedTextBox is supposed to restrict input to only A-Z and a-z.
It appears that the AsciiOnly property is not working.
Am I missing something here?

MSDN says: MaskedTextBox.AsciiOnly gets or sets a value indicating whether the
MaskedTextBox control accepts characters outside of the ASCII character set.

Yes, I already know that.
MSDN also says:
"If true, AsciiOnly restricts user input to the characters a-z and A-Z. ASCII control characters are not allowed. "
But it doesn't work. When I set the Property to AsciiOnly, the MaskedTextBox still
accepts characters other than a-z and A-Z. For example, it accepts comma (,), period (.),
numerals (1-9) etc...
Try it and see!
Is this a bug in .NET 2.0?

The MSDN statement "If true, AsciiOnly restricts user input to the characters a-z and A-Z.
ASCII control characters are not allowed" is wrong. If it were true, the property should
have been called AsciiLettersOnly.

Yes, apparently that is so.
What is the use of having the AsciiOnly property?
It appears to be redundant and non-functional.
Could you provide a scenario or example of how to use this property?

Although .NET characters and strings are Unicode, you might want the user to input a string
that does not contain non-ASCII characters, because what will consume them only understands
ASCII (some legacy system, some native code, a given file format, whatever).

I use c#.net languae
I want to get the system time of computer shut down.
please give me some example code.than you for help me

DateTime.Now will give you the system time. Unless you're using an OS that stores the times it was shut down ( such as Windows Server 2003 ), you can't hope to retrieve that info.

Given:
ArrayList aButtons = new ArrayList();<br />
...<br />
<br />
myBtn = System.Windows.Forms.GetButton();<br />
aButons.Add(myBtn);<br />
Later, I can't seem to do this:
aButtons[1].Enabled = true;
Instead, I seem to have to do this:
Button newButton = (Button) aButtons[1];<br />
<br />
newButton.Enabled = true;
Is there any way to access the object directly in the ListArray?
|
|
|
|
|
((Button)aButtons[1]).Enabled = true;
|
|
|
|
|
Wow, that's totally... intuitive. Anybody know why Visual Studio / C# can't parse it the first way?
On the other hand - thanks! I never would have figured that out.
