Do you know about new line ? ( Like /n in C/C++). If yes then use it.

WriteLine includes a linefeed. You probably want to use just Write

Part of the reason why your program is not working is that you for statements are not proper or for that matter syntactically correct. Their are only 3 arguments in the for loop, you have extra semi-colons all over your for loops. Along with that I cannot see a correct conditional statement in the for loop (the middle paramter).
Try something along these terms
Console.Write("Enter # of lines:");
int temp=Convert.ToInt32(Console.ReadLine());
for(i=0;i<temp;i++)>
{
for(int j=0;j<=i;j++)
{
Console.Write("*");
}
Console.WriteLine();
}
I did not test this code, but it should work. Since this is your homework assignment you will have to figure out how to line up the asterisks to make a nice pyramid. Right now this should produce a right triangle.

Hi,
I have 2 problems with crystal report:

2- when my server (connection string) changes, there is no filxed place to change the servername and the reports that is biuld on a server with name 'A' don't work on server 'B', and should be rebuild in new server.
a place such as Settings can not be used for connectionstring??
Best wishes

Your class has no concept of what ViewState is.
You need to obtain a reference to the class that has the ViewState property and refer to it from there.
If this is the currently executing page, use (Page)HttpContext.Current.CurrentHandler.

i am using a combobox and a textbox control. text box behaviour depends upon selected value of combobox. These properties of combo box are assingned.
AutoComplete = true;
AutoCompleteMode = SuggestAppend;
AutoCompleteSource = CustomSource
AutoDropDown = true;
Further more .net 2.0 is under usage with visual Studios 2005.
in combobox_TextChanged() event i have assigned some value to textbox control. now i want that when user is typing over the combo box then as he types first letter the TextChanged() event is triggered and my textbox values changes accordingly. i want to control it some how so that when user ends typing only then my textbox values are changed. I tried to control it through combobox.selectionStart and combobox.selectionLength properties but thay always give 0 values. So how should achieve my goal??
Furthermore when user start typing over combobox and in case selection changes then no key event is trigered (i.e keyPress(), keyUp() or keyDown() events)but it selection doesn't changes only then keyUP() event is trigered. Moreover event of combobox_SelectionChangeCommitted()is also tested and it is not triggered when user types on combobox.
Any suggestions?
May God help u solv ur problems as well,thx in advance!!

Hello All,
I'm trying to develop a solution that will import data from a text delimited file into an Access table. Because the text file is created daily with a different file name, I just can't link the file directly.
I've loading successful loading the text data into a dataset but this is where I get lost. I sure would appreciate if someone could point me the right direction.
da1.Fill(dsText);<br />
<br />
da2.Fill(dsAccess);<br />
<br />
da2.Update(dsText); //Does not work for me

I need to use some field "ID" a couple of times in loop, say for example 4 times in a loop, which one of these code would be faster ?
<br />
foreach(XmlNode XMLNODE in XML_menu.SelectSingleNode("menu").ChildNodes){<br />
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );<br />
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );<br />
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );<br />
Console.WriteLine( XMLNODE.SelectSingleNode("@id").InnerText );<br />
}<br />
or
<br />
foreach(XmlNode XMLNODE in XML_menu.SelectSingleNode("menu").ChildNodes){<br />
string ID = XMLNODE.SelectSingleNode("@id").InnerText;<br />
Console.WriteLine( ID );<br />
Console.WriteLine( ID );<br />
Console.WriteLine( ID );<br />
Console.WriteLine( ID );<br />
} <br />
What I mean is, is it faster to use "XMLNODE.SelectSingleNode" many times or should I first get its value into some string and then use that string many times?

Option 2 is more readable. The JIT compiler may be able to optimise option 1 to make only one call, and turn it into option 2 - but why make it hard for yourself?
|
|
|
|
|
I'm leaning toward option 2 as well... although, I'm a bit confused regarding "but why make it hard for yourself?", do you mean that I should go with the first option after all?
Thanks
|
|

|

I mean that writing and maintaining three copies of those function calls is making it hard for you, and making the code harder to read.
In general you should write readable and maintainable code. Let the compiler worry about how to optimize it.
|
|
|
|
|
I'm sorry, my english is not so very good. I'm a bit confused on what you mean regarding the code examples above. So option 2 is the better one if I undrestand correctly?
Or should I write it in a totally different way?
|
|
|
|
|
Yes. Option 2 is better.
It is better because it is easier to read.
It is also better because you are only Selecting a Single Node once.
Also if you need to change "XMLNODE.SelectSingleNode("@id").InnerText", then you only need to change it in one place.
|
|
|
|
|
The first, with:
Console.WriteLine
(
"{0}\n{0}\n{0}\n{0}"
,
XMLNODE.SelectSingleNode("@id").InnerText
) ;
|
|
|
|
|
Assuming that you actually need to do more work than just print the value 4 times, option 2 would be the better choice. It is more readable and will only allocate one string instance per loop where option 1 will allocate 4 string instances per loop.
You can also use the Attributes collection on the XmlNode object instead of a second call to SelectSingleNode. In either case, you should be aware that SelectSingleNode (or indexing the Attributes collection) can return null if the node (or attribute) isn't found, so you may want to test for that condition first.

Hi,
I have some simple XML and I want to convert the elements into strings.
My XML looks like this:
<ErrorDetail xmlns="mydomain.com/errordetail.xsd">
<RegVal AX="1" BX="2" CX="3" DX="3"</RegVal>
<RegVal AX="4" BX="3" CX="5" DX="4"</RegVal>
<RegVal AX="5" BX="4" CX="6" DX="5"</RegVal>
</ErrorDetail>
So I want to get the elements out into an array of strings like this:
strings[0] = "<RegVal AX="1" BX="2" CX="3" DX="3"</RegVal>";
strings[1] = "<RegVal AX="4" BX="3" CX="5" DX="4"</RegVal>";
strings[2] = "<RegVal AX="5" BX="4" CX="6" DX="5"</RegVal>";
But I want to do this using an XmlTextReader I think but I have not had success yet.
Can anyone help? Thanks

try the XmlNode.InnerXml property.
yourErrorDetailXmlNode.InnerXml should return a string containing the markup.

If by "item" you mean a form's control, yes. Just iterate over the form's Controls collection.

As I mentioned, this is easy enough to do by iterating over the form's Controls collection and saving whatever information (i.e. properties of each Control) you want.
