hi,
i am new to C# programming, please help me to find a solution for my issue.
in my project i got 2 forms and 1 class file. from form1 i created an object instance for the class and updating some values.
clsClassName object1 = new clsClassName();
how to create a object in form2 to access the updated values.
i know that we can create by ref. like
clsClassName object2 = object1;
but i cant able to see object1 in form2.
when i am doing project in vb.net i will put my object creation in a module so that it will be accessible in all the forms, is there any way to create objects or declare variables which can be accessible globally.
Thanks in advance

u can access the updated value of object created in form1 by passing that object to the constructor of form2

hi rahul,
thanks for your prompt reply, i cant able to find the form constructor.
public partial class frmForm2 : Form
{
public frmForm2() //is this the form constructor.
{
InitializeComponent();
}
}
even here i cant able to see the object1 from form1.

that's the constructor
create a copy of it which takes object1 as a parameter
if you want to keep the reference for the life time of form2 then create an instnace variable and set it to the object1 you passed in

Hi,
you can create a static object for that class.

Hi,
I have a ListView table that contains some files and i would like to know the command that will delete it by clicking some Delete Button.
Thanks in advance for your help.

Probably you mean that ListView contains the path of the files. Then simply call File.Delete, passing the text of the ListView Items.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Well, you can use the ListView.SelectedItems property to retrieve a collection of all items that are currently selected. Iterate over the returned collection and for each item delete the respective file by using classes from System.IO namespace (if you really want to delete on the file system) and finally remove the item from the list view via ListView.Items.Remove method.

what is escape sequencing? how is it useful in c#/Asp.net 2.0?
thank you
|

An escape sequence is a combination of characters that has a special meaning. The term escape sequence comes from the sequences used with things like a line printer, where the first character is the ESC character.
Escape sequences are used for example in URLs, HTML code, XML code, SQL strings, Javascript strings and C# strings. They are used to insert special characters that can't normally be written.
In URLs the escape character is %, in HTML and XML it is &, in SQL strings it is ' or \ depending on database, in Javascript strings and C# strings it is \.
Some common escape sequences:
C# strings:
\" = quote character
\r = carrege return (character code 13)
\n = line feed (character code 10)
HTML:
& = & character
" = " character
< = < character
> = > character
URL:
%26 = & character
%3f = ? character
%2f = / character
%20 = space character
%25 = % character

"\u000a" and '\u000a' however those are in unicode. To get the ascii value you would need to use an Ascii Encoder and grab the bytes but why bother, just write 0xa to the stream.

I don't think that's going to fly for a lot of circumstances.

The paradox of your question is that you are wanting to use a generic container for content which cannot necessarily be processed generically.

watch out there, using "urgent in your post subject is not a good idea

Does anyone has positive expirience with comboboxes that can be bound to nullable properties? I'm developing application in which I often bind ComboBox to DataColumn (with AllowDBNull set to true) of typed DataSet. It works fine but if user selects item it can no longer say - hey set that to Null.
Ideal solution would be something like new DateTimePicker - having ShowCheckBox property and if it is Checked get selected Date, if it is Unchecked get DBNull.Value. (see image below I referenced from one of CodeProject articles)
So any suggestions or I am damned to make control myself?

i had the same problem a few months ago and i also hadn't found a good solution. my workaround was a union including my datatable and an "empty" datarow.
