Can I get a whole column in a matrix with doubles with some command? For example if I want the fifth column: something like
Matrix[(all rows), 5] ?
Thanks

Depends on the data structure, which Matrix class do you use? .NET does not have a built in one, but XNA for example does.
If it's just a two-dimensional array then you can simply loop over the n-th item in each nested array to get the values for one row.

You can declare a symbol for your whitespace, something like: "thisisawhitespace" or "nonblankspace" or ...
While (true) { Human.isLearnable = true; }

string acl = "thisisawhitespace"; or
string acl = "nonblankspace"; or
Something that you can recognize it as whitespace...
Seems forum couldn't show my post correctly, my pleasure 
While (true) { Human.isLearnable = true; }

When the value of a node becomes " " in XML files, you have <YourNode /> but if it has a value it seems like <YourNode>YourValue</YourNode> so if you don't want to have <YourNode /> in your XML file, try putting a Value in it as a WhiteSpace value, Something like values I said before or anything else and while you're reading values when you reach the "thisisawhitespace" or "nonblankspace" or ... you can understand that this is a WhiteSpace,
Maybe there's some other ways to have <YourNode> </YourNode> but unfortunately I don't know anything about them.
While (true) { Human.isLearnable = true; }

As far as I know, if you are getting the situation as described by Pedram, from a programming point of view there should be no problem as they are equivilent, but if you need to preserve the spaces have a look at xml:space="preserve"
Alternatively, is it that your dataset has nulls in some fields and does not create the elements/attributes at all?

Thank you!!!! I was wondering when someone will actually come up with the proper answer 
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - coming soon ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

Hey, tick the "Ignore HTML tags in this message (good for code snippets)" check box. 
While (true) { Human.isLearnable = true; }
|
|
|
|
|
I use an attribute:
<PUlat Align="right" Hide="false" Null="true" />
then if I use XSLT to transform the XML to HTML I can insert a non-breaking space in place of the null.

We can browse and open the system files using OpenFileDialog Box.How can we open the selected file in a separate window?Can anyone direct me with the code for this, please.

Separate window of your application?
|

You should pass your file info into your "Other Window" (if it's in your application) by its constructor, something like this:
void Button_Click(object sender, EventArgs e)
{
if (OpenFileDialog.ShowDialog() == DialogResult.OK)
{
AnotherForm form2 = new AnotherForm(OpenFileDialog.FileName);
form2.Show();
}
}
and then in your AnotherForm:
public AnotherForm(string filename)
{
RichTextBox.LoadFile(filename);
}
While (true) { Human.isLearnable = true; }

I am not sure what you are asking. Are you confused with the static GetAllAccounts method? If yes, it is a factory method. Read about factory pattern.
|
|
|
|
|
First go through the code.It is simple.One thing is GetAllAccounts()method .it is static so it is accessed by directly Classname because a static mathod doesn't need a call from the instance of the class.
If there is any other point.Feel free to ask.
Cheers!!

Hi Slick69,
maybe this is a security problem. Just select the file in the windows explorer with the right mouse button and choose "Properties" from the context menu. On the first tab you can allow access to this file. Hope this solves your problem.

Hi, 
i see in some articles that after adding a report file you select the dataset.
I really like creating the dataset by code rather than dataset object of c#.
I see i have to drag field of the dataset to the report, it does work fine! i just like to do it in code.
I will try to find out how.
Is there an article on that? any help here?

When you design crystal report, it requires the data schema. It allows to load from a XML file. DataSet has a WriteXML method. Using that write a xml file to the drive. Use this xml file to design your report. Each time you have to fill dataset and assign to report.

I have search the CP site, and Google of course, but still haven't found what I am looking for.
Can you guys give me some links to articles/pages with information on using C# to do Binary Network Streams with C# asyncronously with multiple clients?
I am looking to make a program that sends different types of data back and forth between clients and server. I did get it to work with Remoting, but it gets slow with a bunch of clients. I would like to learn about binary streams anyway and this is a side project that doesn't need done right away. Also, I did get the binary network stream type of connection to work with one client, with only one send/recieve, but then it fails.
I think I might just be using the wrong keywords in my searches, if you know any I should try, send them my way as well.
Anyway, thanks for any and all help, and thank you for your time, I appriciate it.
