Dear All,
In my application, I have a windows service, this will perform some operations and pass the result (dataset) as the object and send back the same to my Windows and Web Application.
For communication I have used .Net Remoting.
I have used the object array as the input and an object as the response for the communication function and it is in the generalized a class inside a DLL.
Now when the response contains the ArrayList (which includes some strings and another ArrayList) it is type casting the object to ArrayList in the Windows and Web Application.
When I am passing the Dataset in the form of object to the front end as the response, it is giving the type casting error.
But while debugging the response in the front end has the Dataset.
Can any one help me to get rid of this?
Thanks a lot in advance.
Best Regards,
M. J. Jaya Chitra

hi there! I have one issue, and maybe someone out there can help me. I have an app, I am using it for processing files from ftp folder. Sometimes there is like a large amount of files, and it takes maybe 30 sec to 1 min to downloaded from the ftp folder. I want to put something like a progress bar where it shows how many files I am downloading, how many I have completed, and how much time the operation will take. Thx ahead for any help!!

the question is how I can do all of the things what I want to do. Like during I am transferring the files on the local disk, I want the progress bar to be shown, instead of not showing anything, plus how many files I am transferring, which one is transferred at the moment like 2/4, and the estimated time the transfer will finish.

Well, you're going to need two progress bars - one to show the percentage of files you've transferred, and one to show the progress of the currently transferring file.
I would use a BackgroundWorker thread to manage the first progress bar, and that fires off an asynchronous ftp transfer (which would update the 2nd progress bar).
It's completely pointless (not to mention, redundant) to have a progress bar that shows the percentage of files remaining, and it's pretty much impossible to determine how long the whole transfer is going to take unless you time the transfer of each file and calculate an average while everything is transferring.

Yeah but sometimes the client likes a bit of glitter on their turd app.
Add up the files, after the first one has finished guess that all the files will take that long and adjust your percentages appropriately; when the second has finished use the average and so on.
For extra points you could also display the name of each file as it is uploaded.

Dear experts,
I have the following problem.
I want to merge 2 xml-files into one automatically.
How can this be accomplished in the best way.
a) by a c#-pgrogram
b) by xslt-transformation
c)...
do you have any link/solution?
Kind regards
|
|
|
|
|
guess it depends on how the merge should work.
if you only need to append one file to another, cmd.exe will do the job.
xslt is fine, but you'll need something that starts the transformation process automatically.

Use the Systemm.IO.FileInfo class.

Hi,
I have a dictionary of items. I want to create a new Dictionary by taking items from it where each item meets a particular criterion. I figure that the ToDictionary extension method would suit my purpose, but for the life of me I cannot get it to compile.
<pre>
Dictionary<int, string> test = new Dictionary<int, string>{
{1 ,"a"},{2, "b"},{3 ,"c"},{4, "d"}
};
Dictionary<int, string> d = test.ToDictionary<int, string>(o => o.Value.CompareTo("d") == -1);
// compiler error on this line
//'System.Collections.Generic.Dictionary<int,string>' does not contain a definition for 'ToDictionary' and the best extension method overload //'System.Linq.Enumerable.ToDictionary<TSource,TKey>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource,TKey>)' has some //invalid arguments
</pre>
The only thing that I could manage that came close to what I need is:
<pre>
List<KeyValuePair<int, string>> t1 = test
.Where(o => o.Value.CompareTo("d") == -1)
.ToList<KeyValuePair<int, string>>();
</pre>
I reckon I'm doing something really stupid but I can't see what it is. Can anyone help me out?
Thanks very much,

This will work for you:
IDictionary<int,string> d = (
from t in test
where t.Value.CompareTo("d") == -1
select t).
ToDictionary(item => item.Key, item => item.Value);

You can simply use ODBC to read data from excel to datatable.

Hi all.
Is exists way to binding cutsom type value to Control through databinding
Example
public class CLASSIFIED
{
public CLASSIFIED(double Val)
{
this._value = Val;
}
private double _value;
public static implicit operator CLASSIFIED(double Val)
{
return new CLASSIFIED(Val);
}
public static implicit operator double(CLASSIFIED CLASSIFIED)
{
return CLASSIFIED._value;
}
}
class SourceProvider
{
CLASSIFIED Index {get{...} set{...}}
}
...
control.DataBindings.Add("EditValue", _sourceProvider, "Index");
...
I know what i can do it through IFormatProvider interface like what : control.DataBindings.Add("EditValue", _sourceProvider, "Index", null, null, _myFormatProvider);
But what about other way, derive my custom type from AN INTERFACE what DataBindings.Add(...) recognize and format my custom type value automaticaly????
<br />
public class CLASSIFIED : ISomeInterfceWhatDataBindingRecoginze<br />
{<br />
....<br />
}<br />
}<br />
THANK!!!
