I don't know.
you can test it. if you find the email you send to localhost, you are correct.

Im a VB.NET programmer currently working with C#, I am having following questions.
How to create a function with optional parameters ?
Is there any function exist like "CallByName" in VB.NET ?

And in a matter of moments, you've found the one thing that VB.NET has and C# does not. I have complained to the C# team, they don't care.
So, you need to create two methods, one with the extra param, and one that calls the extra param version with the default. Sucks, I know.
iprasad007 wrote: Is there any function exist like "CallByName" in VB.NET ?
Depends, what does it do ?
Just googled. VB.NET still does that ? That sucks. You should stay clear of anything in the VisualBasic namespace, that's .NET pollution right there. You can use reflection to find methods on an object, perhaps that will do what you need here.

Thank you so much Christian.
So in first case I need to code same Business Logic twice, or is there any standard method to write the function once and prototyping it many times ?
For instance I can write function with all params ones, then can write many functions with same names but with few parameters then of original. But still i need to write code to call original function hence the overhead of maintaining all the functions (while change or documentation). Is this is the last way to do ?
And now about my second question, sorry really I didant got what shud I do when I need to call a function or set a property by softcoding such as CallByName does in VB.NET.
Waiting for your reply
Prasad
P.S. BTW ur blog is good

*blush* thanks. I need to post something on it tho.

Only ever code your business logic once. Like this
int SortStuff(SortBy sortBy, SortOrder sortOrder
{
// lots of sorting code
}
int SortStuff(SortBy sortBy)
{
return SortBy(sortBy, SortOrder.Ascending);
}
Note, the enums in this method are made up to make the point.

Why would you want to do such a thing ? I think it sucks, I don't see how that method is in any way validating that the method in question exists. If you want to discover methods and call them, you need to use reflection ( google reflection C# and you'll see it's a complex subject, but it's exactly what you need here ).
Worst case scenario, you can import the VisualBasic dll/namespace into yuor C# app and call the old VB methods, but ideally you shouldn't do that, even if you're using VB.

No no I would not do that. I need such functionality for a usual requirement, i.e. to clean all controls in a container. As usual I have wrote a foreach control block for looping through all the controls, depending upon controls type im planning to call its clear method or .Text = "", some controls on my form or container requires some other methods to clear them. Hence needed that function.
I think I need to dig in reflection.
Thanx for ur replies.

If that's all you need, then you can use as.
For example
foreach ( Control c in Controls)
{
TextBox t = c as TextBox;
if (t != null ) // c was a TextBox
{
t.Whateveryoulike
}
// and so on
}

Great tip indeed ...
I have done by following way,
foreach(Control ctl in this.Controls)
{
if(ctl.GetType() == typeof(TextBox))
{
TextBox t=ctl as TextBox;
t.Text ="";
}
else if(ctl.GetType() == typeof(CheckBox))
{
CheckBox t=ctl as CheckBox;
t.Checked =false;
}
}
Thank you so much for ur kind help, now im feeling that im doing it in right way, and also i havent forgot to write ur name in comment of my code  (alog with url to this page).

Hello,
You better should go on with what Christian Graus told you.
foreach ( Control c in Controls)
{
TextBox t = c as TextBox;
if (t != null ) // c was a TextBox
{
t.Whateveryoulike
}
else
{
CheckBox cb = c as CheckBox;
if(cb!=null)
{
cb......
}
}
In youre case you ask the Type info 2 times. (takes a little longer)
(I also learned it some time ago, from Christian Graus I think) 
All the best,
Martin

As someone said, typeof is kind of redundant. The only reason I can see to use it is that you may be able to switch on ctl.GetType(), and a switch is always better than lots of else if statements.
I'm sure that 'as' would use getType, so the most efficient way if a switch won't work would probably be to store the result of typeof(ctl) and use it without calling it every time.

Hi All Respected Programmers
VB6 Method => Form2.Text1.Text = Form1.Text1.Text
Kindly guide me, how may I use said method in C# ?
Thank you very much in Advance
|
|
|
|
|
You need to create objects of both the forms and then u can use same code just by adding semicolon after it, such as
Form1 x=new Form1();
Form2 y=new Form2();
x.Text1.Text=y.Text1.Text;
|
|
|
|
|
The advice you were given is sort of right.
If you create new instances of Form1 and Form2, they will not relate in any way to instances that are in use in your app, so the call will do nothing, you need to use the instances that are in use, I assume you're in form1, and you want to call form2, in which case, you need the instance name for the Form2 instance, and drom Form1 entirely from the code snippet.
Your text box controls are also probably private, and instance of changing that, you should add properties that set the text of the textbox to the controls.
Also, I assume these are not your actual variable names ?

I want to be able to check which control the focus is moving to, when a particular control is losing the focus.
Bascially, I have a text box, that when you type into it displays an autocomplete list. If the focus is moving away from the text box to some other control, I want to hide the list. However, if its moving TO the list, then obviously it needs to stay shown.
There doesn't seem to be anything in the .Net events that indicate where the focus is moving. Is there perhasps a message I can send that discovers it?
Thansk in advance
phil

Thanks for all your non-replies I seem to have found out how to do it..
The easiest way is to in the OnLostFocus event handler, to first call the base.OnLostFocus. When control returns to your code, whichever control the focus has moved to will now have its .Focused property = true.
<br />
protected override void OnLostFocus(EventArgs e)<br />
{<br />
base.OnLostFocus (e);
if (!autoCompleteBox.Focused)
autoCompleteBox.Hide();<br />
}<br />
Regards,
Phil

If you just want to hide/show the autocomplete list, you can use
event Enter and Leave from the textbox to detect GotFocus/LostFocus

Hello
Well! I was just typing that answer when you modified your post!!?
Anyway, I still want to add that if you are using .Net 2.0, you should use the TextBox.AutoCompleteSource property instead, which is a built in AutoComplete.

Hi Nader,
Yes, unfortunately this does for now need to be supported in .Net 1.1, and I don't really want to maintain two code bases.
Thanks for your reply though.

I've looked everywhere. I've played with the Microsoft SGML component. I've played with the .NET wrapper of the COM wrapper of Tidy HTML. I've even thought of porting my 10 year old C++ HTML parser and correcter I wrote while bored over to C#.
But I'd rather just beg, borrow or steal (or even, and I'm this desperate) buy a .NET component That Just Works.
Does anyone have any recomendations?
|
|
|

|

They both use SGMLReader, and unfortunately the implementation as it's provided HTML-encodes already encoded HTML entities within PRE tags.
ie
<pre>
>
</pre> Comes out as
<pre>
&gt;
</pre> I'm beyond patience with trying to cobble together bits and pieces. I just want a simple, effective, efficient, thread safe component with one method:
public string HtmlCleaner.ConvertHtmlToXhtml(string inputHtml);
It's gotta be out there somewhere...
