I have a public class constructor that reads a file's content. If the file does not exist or the file name/content is wrong, it raises an ArgumentException. I'd like the constructor to return a null object on an exception ie
MyClass mc = new MyClass(string filename);
mc is a valid object if the filename and content is OK, otherwise its null. At present I can create a partially instantiated object, check if a property is null, and fix the problem, but this is inelegant.
Is there a way to do this or am I out to lunch?
Suggestions?

Out to lunch. You might want to look at the Abstract Factory design pattern [^] to get what you want.

Hi sjdevo3gsr,
do one thing, simply put your constructor code in try catch Block. Here make sure htat take many catch blocks. like this
try<br />
{<br />
}<br />
catch(ArgumentException argEx)
{<br />
}<br />
catch(Exception ex)
{<br />
}<br />

use the factory pattern for this;
declare a static function that returns this class initialized returning null and use this function instead of new operator.

In C++, you could overload the new operator, but you can't do anything similar with C#.

|

for example in this site :
http://www.google.com/advanced_search?hl=en
how i can choose an option in any of the multiline combo boxes?
like Language, File Format.....
i mean for example in Language i wanna select some language
and in file format i wanna select pdf
thx in advance....

What I'm trying to do in psuedo code
<br />
foreach( item sourceItem in sourceList)<br />
if (destList.Count == 0)<br />
destList.Add(sourceItem)<br />
else<br />
foreach (item destItem in destList)<br />
if (Conditions(...))<br />
AddAndManipulateExistingItems(...)<br />
else destList.Add(sourceItem)<br />
AddAndManipulateExistingItems() adds 1 or more items to destList and may modify sourceItem and existing items destList. Source list is not kept past this code snippet so modifying it doesn't matter. The algorithm itself is from a vba excel app and is sufficiently complex that I don't want to risk hunting down any side effects burried in several thousand lines of implementation.
My first attempt to do this was done using ArrayLists, but the modifications are breaking the foreach loops and causing InvalidOperationException's. IS there a collection that will let me do this, or will I have to use arrays and resize manually?

The foreach construct uses an Enumerator to step through the list. If you alter the list, the Enumerator is invalidated. You can loop through the list as long as you don't use an Enumerator, for an example using a regular for loop:
for (int i=0; i<sourceList.Count; i++) { ... }

Set the timout for the request to a lower value, perhaps just a few seconds.
An alternative is to make an asynchronous request instead.

b { font-weight: normal; }

I setup the request timeout already.
the problem is, I send the request, and it (request) returns a response already. the "timeout" happends at when I deal with the response.

What do you mean? If you already have gotten the response, what does it have to do with the internet connection?

b { font-weight: normal; }

I want to download a very big file, it takes for example 10 minutes, so I have to know if the internet connection is broken in this 10 minitues. so I can stop waiting .

Look into using an asynchronous request, then. I think that it might be possible to track the process of the request.

Hello.
I am trying to change some datagrid row colours. I've already created a new paint function that needs the following parameters:
System.Drawing.Graphics g,
System.Drawing.Rectangle bounds,
CurrencyManager source,
int rowNum,
System.Drawing.Brush backBrush,
System.Drawing.Brush foreBrush,
bool alignToRight.
Then I want to call this function in the datagrid paint event but I need the correct parameters.How can I do this???
Thanks.

Creating a tool that will query the wmiClass of "client" PCs.
I do not want to have any software installed on the client side,
all clients are behind the same router, so I don't have any concerns there.
I'm looking for the best way to connect to aprox 100 PCs. -- the intended operation would be: user clicks button, button event polls pcs, listener client logs all replies, using list of replies poll each pc for all required info (i'd like to just udp the clients with the wmi login info, and query so that it just replies with the info, but not sure yet if that is possible or even a safe move)
looking for any good ideas or previous attempts that were sucessful in doing this.
I've considered using UDP to conduct an initial poll of the PCs, then use the returned name of the pc to conduct the TCP request of wmi.
I've also considered using a static list of IPs, but dont like that idea, so maybe a semi-static ip list?
and lastly i've considered finding a way to intergrate with active directory to return a list of pcs, which is fine, as long as we don't have any non-registered clients
again, just looking for any thoughts of a good way to do this...and of course if you know of any refrence material that is open for use that would be much appreciated as well.
string Beautiful;
Beautiful = "ignorant";
label1.Text = "The world is full of " + Beautiful +" people.";
Why is common sense such an un-common comodity?
