Create new byte array ,which length is the sum of the source arrays lengths and use System.Array.Copy to copy source data to the result array.
Life is a stage and we are all actors!

Once an array's size is declared, it cannot be changed so you can't append directly to the end.
If you know the end size you need then you can declare a new byte array, and use Buffer.BlockCopy to copy from other arrays into the new one specifying offsets where needed etc.
If the end size is unknown, I'd use a List<byte> and use the Add method to copy a byte or AddRange to copy other byte arrays into it, then call ToArray on the List<byte> at the end, and you will then have an array of the correct size.

I've been pondering on this a little more - these two methods may help. The first will append one or more individual items, the second one or more collections of items. These may not be the fatest, but they work.
public static T[] AddElements<T>(T[] currentArray, params T[] element)
{
T[] result = new T[currentArray.Length + element.Length];
Buffer.BlockCopy(currentArray, 0, result, 0, currentArray.Length);
for (int i = 0; i < element.Length; i++)
result[currentArray.Length + i] = element[i];
return result;
}
public static T[] AddElements<T>(T[] currentArray, params IEnumerable<T>[] elements)
{
List<T> resultList = new List<T>(currentArray);
foreach (IEnumerable<T> item in elements)
resultList.AddRange(item);
return resultList.ToArray();
}Some examples of useage:
byte[] currentArray = new byte[] { 0, 1, 2, 3, 4 };
byte elementA = 5;
byte elementB = 6;
byte elementC = 7;
currentArray = AddElements(currentArray, elementA);
currentArray = AddElements(currentArray, elementB, elementC);
byte[] elementsA = new byte[] { 8, 9, 10 };
byte[] elementsB = new byte[] { 11, 12, 13 };
List<byte> elementsC = new List<byte>() { 14, 15, 16 };
currentArray = AddElements(currentArray, elementsA);
currentArray = AddElements(currentArray, elementsB, elementsC);

Hello
I need to view pictures of a file now this file has many pictures i need a way to access the first picture then navigate to the last one, the problem is that the images are not numeric named so i cant increment number to access the other image please help.
|
|
|
|
|
What have you tried?
What are they named?
Do you have an index of some sort?

i am trying DirectoryInfo class to get the files inside of it in file info array then i would iterate around them but am facing problems you cant know what the names of the picture bcz it is the client's disicion and there is no index or sort.
|

Then you will have to sort them by name, or create date. If the user doesn't catch on fairly quickly that sequential naming is a good idea if you want to find things, then spell it out to him when he compains...
DirectoryInfo di = new DirectoryInfo(@"c:\XXTemp");
FileInfo[] fil = di.GetFiles();
is the way to go.

string[] picFiles = Directory.GetFiles(@"D:\PICS");
foreach (string picFile in picFiles)
{
pictureBox1.Image = Image.FromFile(picFile);
MessageBox.Show("Press OK for next picture...");
}
The pictures are unsorted. If you don't have any index, then sort "picFiles" to date and time.

Hello, there is no need to put Bold on entire message. Your question conflicts with the title.
Are you looking for next image in same folder or are you looking how to get next frame in Animated Image (GIF)?
EDIT: I didn't saw other post, because my Firefox has cached and i saw old page.
You don't need to know names of file. You can actualy parse the order. You coud by Character code.
Also if you chose by date time, it desn't mean it will be accurate. If it was taken by camera, and you change batteries, there is possible date information could reset and new files coud have wrong DateTime

I databinded the gridview to datatable and displayed the fields.But the edit of gridview is not working..I am getting the following error.
'The GridView 'GridView2' fired event RowEditing which wasn't handled.'
Can anybody help me with this?
|
|
|
|
|
For this You have to register Gridview2_RowEditing Event in Code behind.
For example :
protected void GridView2_RowEditing(object sender, GridViewEditEventArgs e)
{
//Write your editing Code here.
}
And for cancelling editing, You need to register Gridview2_RowCancellingEdit event.
For Example :
protected void GridView2_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
}.
You can visit MSDN for further information http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowediting.aspx[^]
Hope this will make sense to you.

how to check weather all field of table has filled or not???
|
|
|
|
|
Is this to be done in the UI (validator and should be in the ASP forum) or in the code behind in which case you check the controls on the form or the datatable has null values.
|
|
|
|
|
We have an ASP.NET forum. The documentation on validators is also very clear, with lots of examples.

all fields of table means what? 
Do you mean all field entries are filled or not? If so you can check each individual values that user feed in....
You can also place asp:RequiredFieldValidator for each controls
Or while executing the insert statement, loop through Parameters of command object and see of value of any parameter is null....

what do mean by table DataTable or an asp Table , or an Html table with tr and tds ??? please be more specific

Hi!!!
i need to pass some objects from on form to another, using events. the main form does not calls the sec  ondary form, it is being called from somewhere else. So i cant use any of the things listed in this article.
Passing Data Between Forms[^]
i tried to use Microsoft unity block (Event broker) method, but it didn't work for me as posted in this article.
http://elegantcode.com/2008/04/09/unity-10-eventbroker-sample-cab-style/[^]
Others methods can be using windows message queues or database.
Is there any other solution. Please i require some help urgently. some code will be appreciated.
Note: Performance is a major issue in my App as i am building a tcp server with some live mapping. And if anyone has a working solution using subscriber/publisher in event broker, it would be highly appreciated.

Why can't you wire up a class with the data and have it implement Inotify events and have both forms subscribe to the events.
