Not sure what you mean here, mind you, the question was asked by the president of the United States if one can trust the pop-up.

Why? If you want to write a bug tracking application, surely you have some requirements already? Surely you know what problem you are trying to solve.
You should never, ever, start developing software based purely off the title of an application. You need to find out what people want from your software. Talk to the people who will use this software, find out how they want to use it and then prioritise your development based on that. Not all features will make it in because often what you will hear as requirements tend to just be wish list for one particular user. If you hear the same feature from lots of users though, it would seem wise to prioritise that in your development. Good luck.

I have built a program with multiple DataTables and using multiple dimensions for the DataSets. The tables have about 10,000 records and are about 30 levels deep.
I am considering changing this whole scheme to make the DataSets 10000 tables deep and records 30. This makes it better for Adding, deleting, and moving records.
I read the Maximum columns and records for DataTables are 2,147,483,647. However I have not found anything that says there is a maximum number of tables in a dimension of a DataSet. Can anyone tell me if there is and if there is any problem I may wish to consider with the above.
Thanks in advance.

Opinion - you are heading for a disaster!
I don't know your data design but if you are pushing the limits of the container then you are doing something terrible wrong.
I NEVER return more than 1 table at a time from the database, very early on I once got 3 table in the same dataset and the response time was abysmal, getting 3 tables separately was dramatically faster.
I always use the HeirarchyID principle (but as a string not a HeirarchyID) /Parent/C1/C2/C3/C4/ your can then identify the position in the structure and the parentage of any element from the content of the heirarchyid.

I do not need to change the DB only how I distribute the data to the datasets on receiving. Currently I am constantly moving data in the DataTables. If I am able to delete a record and add another record at the end of the table this is much more efficient.
Furthermore, I found that if I transfer all my data to CSV files it is much faster than for storing and loading from a DB. I do not need a relational DB, I only need to store the data. Then load to my program when starting.

Hi,
Can you kindly shed some light on what's wrong with the below code?
Many thanks,
private Image DownloadImage(string _URL)
{
try
{
WebClient client = new WebClient();
Stream stream = client.OpenRead(_URL);
Image img = Image.FromStream(stream);
stream.Flush();
stream.Close();
return img;
}
catch (Exception e)
{
MessageBox.Show(e.Message);
return null;
}
}

looking at the full exception, not just its messge, would tell you exactly where it happens

Too little information - however, if you are getting a WebException, either your URL is not valid or there is some error while downloading data. Check that the URL you are passing is correct.
|
|
|
|
|
MessageBox.Show(e.Message);
what's message? if the _url is valid, open(_url)'ll back e.Message
|
|
|
|
|
private void button1_Click(object sender, EventArgs e)
{
WebClient wc = new WebClient();
wc.DownloadFileAsync(new Uri("http://www.xxxx.com/xx.gif"), "D:\\xx.gif");
wc.DownloadFileCompleted+=new AsyncCompletedEventHandler(wc_DownloadFileCompleted);
}
private void wc_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("完成!");
}

Works like a charm
Thank you!

|

Ahem. You forgot to reallocate the reference to your event handler.
|
|
|
|
|
Did you check the OpenRead explanation on MSDN[^]?
ArgumentNullException
The address parameter is Nothing.
WebException
The URI formed by combining BaseAddress, address is invalid.
-or-
An error occurred while downloading data.
