Hi,
I am adding buttons like this,the event is fired from onInsert of the CollectionBase derived class ButtonList
void _ButtonList_OnCustomButtonAdded(CustomButton newCustomButton)
{
int customButtonWidth = 0;
foreach (CustomButton customButton in _tabPagesList)
{
customButtonWidth = customButtonWidth +
customButton.Width;
}
newCustomButton.Left = customButtonWidth - newCustomButton.Width;
newCustomButton.LeftPos = customButtonWidth - newCustomButton.Width;
newCustomButton.Top = 0;
Graphics g = this.CreateGraphics();
float width = g.MeasureString(newCustomButton.Text, BoldTabFont).Width;
newCustomButton.Width = (int)width;
newCustomButton.Parent = this;
newCustomButton.Show();
newCustomButton.Click += new EventHandler(newCustomButton_Click);
newCustomButton.OnCustomButtonMouseDown += new CustomButton.CustomButtonMouseDown(newCustomButton_OnCustomButtonMouseDown);
this.Controls.Add(newCustomButton);
newCustomButton.BringToFront();
}
buttons added are movable at design time
Thanks,
Tushar

Any suggestions resolving this kind of staff?????

As the class and the code that uses it are in separate namespaces, you either need a using statement to locate the namespace of the class, or you have to specify the complete namespace everytime you use the name of the class.

Hi,
I need to send startDate to a Service like following format.But I need to send it as a DateTime Object NOT like string format.So How do I send following Date with DateTime Object?
<startdate>2007-07-29T00:00:00.0000000+05:30
Please kindly reply me.
Thanks in advance.

Hi,
DateTime is a serializable class, and there is no issue sending it to the Services like "Remoting" server as a parameter of a interface function call.
Also, if you are trying to send it to the other service which has been written using C#, you can serialize the DateTime object and send it as "byte" data, and get it deserialized at the sever end.

Hi,
Thanks for reply. But in my XML Web Service,There is a DateTime Property called "StartDate".
So I need to send following format to there as a DateTime object.
2007-07-29T00:00:00.0000000+05:30
Problem is how can I send +05:30 with the DateTime object?.
Thanks in advance

why dont you use one more parameter for the Time Zone value.

hi,
We are unable to change the xml webservice.We can send request to service and take response.
In the Request we need to send StartDate with Time Zone.
Thanks in advance.
|
|
|
|

Maybe this helps
string dateformat;
TimeZone localZone = TimeZone.CurrentTimeZone;
dateformat = DateTime.Now.ToString("yyyy-MM-dd") + "T" DateTime.Now.TimeOfDay.ToString() + localZone.GetUtcOffset(DateTime.Now);
dateformat gets somting like:
"2007-05-21T18:26:24.8906250-03:00:00"
you may need to cut the last ":00".
Replace de DateTime.Now for the DateTime Object you need to send.

hi
Iunderstand how to use :
public test: Interface
{
}
but,
what is the meaning of this statement:
Isomething x ;
I saw it in :
Icontainer component = null;
and
Excel.application app = new Excel.application();
how can I use the above?

An interface guarantees that a class will implement some methods. Suppose that you have an interface called IPlugin that contains one method called DoSomethingFunky. The interface is to be used as the basis for all plugins for your application. Now, in your code you don't know what the external classes are going to be and you certainly can't compile against them so you need some method for creating these unknown classes. Well, you can do this by using
IPlugin plugin = null;
plugin.DoSomethingFunky();
Deja View - the feeling that you've seen this post before.

It is a variable declared with an inteface type instead of a class type and can hold any object that implements the interface.
To give the simplest example, if you have:
public interface IMyInterface{}
public class ClassWhichImplementsMyInterface:IMyInterface{}
You can use the following in your code:
IMyInterface MyVariable = new ClassWhichImplementsMyInterface();
A good example of the usefulness of this in the .net framework is the foreach statement which will accept any object that implements the IEnumerable interface. It uses objects that implement IEnumerable and knows how to handle them based on that interface.

do you knows how it works
in Excel namespace?
the code goes:
Excel.application app = new excel.application();
Excel.application is an Interface!
but I don't need to implement any of the Excel.application interface, I just use it's methods
like a regular class.
p.s. It's shows in msdn also.

After reading this post, what do you think the first website would be that anyone is going to go to to find this?
What do you think they'll type into the little search box?
How much do you want to bet that what you seek will be the first item listed in the results?

Hi,
I'm assigning value to a DataSet ds (from SQL database) in button A Click event and I set this dataset as DataSource for my grid.
Next if I check the value of this DataSet ds in another button click event, I can't get its value. ds is a Class variable, but I still can't get its value.
The DataSet has one table, which I can see in button A Click event, but in another button event click if i Check the values of ds.Tables.Count, its zero. I'm not manipulating the DataSet anywhere. Could anyone tell me why this happens?
Regards,
Blumen

Your post contains some ambiguity.
blumenhause wrote: ds is a Class variable
What do you mean by class variable?
Do you mean:
* static field
* member instance field

So, which is it? Either you can see the dataset or you can't.
Is this an ASP.NET application? If so, remember that state is not maintained between postbacks.

Yes, this is a private Class variable or a field (its declared inside the class outside all Methods)
This is an ASP.NET code-behind file. But there is no post back here. I click Button A and dataset gets filled with data. Now I put a break point in button B click event and inside that button I check if this dataset using Quick Watch in VS 2003. But although inside Button A click event handler the ds showed 1 Table, inside B's click handler its showing zero Tables.

Is this in ASP.NET pages?
You might have a postback problem...?

I think the page is redeclaring the DS when you click the first button.
Try to add the DS to viewstate.
Then in the 2nd button, use the DS from viewstate.
