Here's a couple of tips you can use:
1. create an array to hold your values
2. create an additional temporary array
3. iterate (for loop is preferable in your case)
4. in each loop, you'll have to compare a value from the array of original values with those already in the temporary array, and add it "sorting logic must be implemented here"
5. once sorted, simply pick the last value in the temp array by moving to its last index
another way to do it is to use two nested loops.
Good luck!

I found the DoubleClick event for Button does not work in Visual C#.
Although you can add the DoubleClick event handler but it does not work. Actually, in the event list, you can not find the DoubleClick event selection.
Any one can tell me whether I can realize the DoubleClick event for Button?
thanks.

The MouseClick property for a button accepts MouseEventArgs. These arguments contain a property called Clicks which identifies the number of clicks. However, for a button this is pretty much useless because the button is designed to respond to single clicks. Double click behaviour is outside the normal behaviour of a button.

I have some code samples that uses the Cargo database, and for one or other reason I do not have the complete database. Can anyone provide me with a link where I can download this database.
Thanks

I've never heard of it. Where did the samples come from ? Did you try google ?

I have no idea. In my quest to get my hands on sample code, I have accumulated so may samples code, ePages etc. This seems to me from a book that have labs and or modules. The one module, Mod08 has three samples, DataFormWizard1, DataReader and XMLData. This is about all I know. And there is no indicatoion in the sample code wher it is coming from.
Thanks

I want to realize the following:
I have created several buttons, each of them has a name related to a function (i.e. the function name is the same to the button name). Now I want to call the corresponding function according to which button you click. Of course, you can not use "switch" or "if" conmmands to realize it. because the buttons as well as the funcitons are not fixed.
for example, I have buttons with name A, B, C,...
there are also the corresponding functions void A();void B(); void C();...
I want to call void A() if you click button with name of "A", I want to call void B() if you click button with name of "B", and so on.
Could you please give me an simple method for that?
thank you very much.

OK - assuming that your buttons and functions have better names than A, B and C, you could use reflection to handle this. Off the top of my head, I would expect that you could handle this with:
private void ButtonHandler(object sender, EventArgs e)
{
string name = ((Button)sender).Name;
this.GetType().InvokeMember(name, BindingFlags.InvokeMethod | BindingFlags.NonPublic | BindingFlags.Instance, null, this, new object[] { });
}Then all you would need to do is wire up your buttons to this one event handler.

HI,
I'm using FtpWebRequest class to provide ftp communication in my application. All is fine, except it sometimes fails. I've tried everything what I could, it just sometimes fails - throws
System.Net.WebException: The remote server returned an error: (500) Syntax error, command unrecognized.
at System.Net.FtpWebRequest.SyncRequestCallback(Object obj)
at System.Net.FtpWebRequest.RequestCallback(Object obj)
at System.Net.CommandStream.Abort(Exception e)
at System.Net.FtpWebRequest.FinishRequestStage(RequestStage stage)
at System.Net.FtpWebRequest.GetResponse()
To be more specific - it is download command (WebRequestMethods.Ftp.DownloadFile).
It runs on a speparate thread in background worker, code :
<br />
FileStream clientStream = new FileStream(this.DestinationPath, FileMode.Create);<br />
FtpWebResponse response = (FtpWebResponse)this.Request.GetResponse();<br />
this.GotResponse = (response != null);<br />
<br />
Stream ftpStream = response.GetResponseStream();<br />
<br />
this.ContentLength = response.ContentLength;<br />
<br />
int bufferSize = 2048;<br />
int readCount;<br />
byte[] buffer = new byte[bufferSize];<br />
<br />
readCount = ftpStream.Read(buffer, 0, bufferSize);<br />
<br />
long dataTransfered = 0;<br />
<br />
while (readCount > 0)<br />
{<br />
if (this.Worker != null && this.Worker.CancellationPending)<br />
{<br />
canceled = true;<br />
this.Request.Abort();<br />
break;<br />
}<br />
<br />
this.CheckPause();<br />
<br />
lock (this)<br />
{<br />
this.lastLoadedSize += readCount;<br />
} <br />
<br />
dataTransfered += readCount;<br />
<br />
clientStream.Write(buffer, 0, readCount);<br />
<br />
if (this.ContentLength > 0)<br />
{<br />
int completed = Convert.ToInt32(((float)dataTransfered / (float)this.ContentLength) * 100);<br />
this.ReportProgres(completed);<br />
}<br />
<br />
readCount = ftpStream.Read(buffer, 0, bufferSize);<br />
}<br />
where this.Worker - Worker object that provides thread for running.
I dont know if it is a problem inside WebRequest class or in my code(where ???) .
Thanx for any help!!

Chances are the server doesn't understand one of the commands being sent. Check out this[^] for more information.

I had a similar problem when accessing Microsoft's forums site through IE. Try flushing your cache (and delete any microsoft.com cookies) or switching browsers.
Take care,

I don't thing that server doesn't recognize that command, because it works most of the time. It fails only from time to time, unpredictably.
It's behavior is like races when doing multi threading (of course it is done using separate threads, but the whole operation runs on one thread -> Get Response, Download data (write data to HDD), Close stream).
I'm desperate

The link that partymonkey posted has a method for gathering some trace information, which may help you debug the issue.

how can i make item in combobox invisible? the item is in middle of combo if i remove it. it will effect the whole indexing so i want to make it invisible
|
|
|
|

Hi,
I don't think that it's possible to make it invisible.
if u can't rely on indexes, create wrapper for your object, where U can add a int field with index(key, whatever). Then just get the SelectedItem and if it's not null, read that item index. Override ToString() method of your wrapper object, to make combobox display whatever tou want to display.

hope that helps

I have one simple but difficult problem:
I plot some lines in a panel with Graphics in C#, now I want to select one of them to edit it.
I don't know how to select it?

Hello,
You have to do it all by yourselve, AFAIK.
I think the fastest way is to handle the MouseDown and MouseUp event of the Panel.
Save the two MousePoints, as this will discripe an rectangle, SelectionRectangle.
Then you have to iterade over all your lines and validate each of the lines.
You could use the IntersectsWith method of the Rectangle class for that.
Hope it helps!
All the best,
Martin
