Hey,
Could someone please point me into the right direction as to what I'd need to use in order to retrieve the size of a file on the web, without downloading the whole thing.
Thanks

You won't know unless you try to download the thing. There's nothing in the HTTP spec that allows for this.

Try inspecting the ContentLength when you using WebRequest and see if it helps.

Well I solved my own problem with some help from google.
If anyone was wondering on how you do this - I achieved it with the following code:
WebClient client = new WebClient();
client.OpenRead("http://www.website-here.com/");
string fileSize = client.ResponseHeaders.Get("Content-Length");
That's about it.

Hi all,
I'm new to C# and currently writing an application for a Windows Mobile 5.0 device using the WebBrowser Control. Now, I'd like my application to process some hyperlinks, instead of the WebBrowser sending a request to the webserver.
There is a possibility to call back a method from within an HTML document (by defining an onclick event in a hyperlink: onclick="window.external.TestMethod('teststring')"). But this does not seem to be supported by WM 5.0 (I can't find the ObjectForScriptingProperty I would have to set, for instance), or am I mistaken?
Is there any alternative way to intercept a click on a hyperlink, some kind of work around? I'm grateful for any kind of help.
Thanks in advance.

Does anybody know, how the System.Reflection.Emit.EventBuilder works? How can I define a simple event with it?
|
|
|
|
|
|
I haven't any problem with Emit technology, excepting EventBuilder class.
It's simple to create an "event" as ilasm does (using delegate field, public methods add_* and remove_*)... but it isn't an event(Type.GetEvent(...) returns null)!
EventBuilder perfoms three interesting methods - SetAddOnMethod, SetRemoveOnMethod and SetRaiseMethod.
And... what's the methods body should be? ILasm way? If yes, how can I get a delegate field for EventBuilder based event?

Hi all,
Are there any controls in C# that can be used as a standard old StringGrid? The DataGrid looks nice and all but it seems to require a DataSource and I'm not using one.
Basically, I just need a way of visually representing a two dimensional string array. OK, maybe not just representing, I need for the user to be able to edit fields in this grid during run time.
Any suggestions?

|
|
why not create a 2 column array and allow the user to edit it and then apply it as a data source to the grid?

Sounds good, but how do I apply a 2D array as a data source to a datagrid?
|
|
|
|
|
you have two choice
either you create a 2-column data table
or
create a class with two properties and use the collection as an object data source to the data grid

Sir/madam,
I wanted to know the basic difference between internal and internal protected .As i know both are accessible with in the drive class. and both are accessible under the object of their class.Both are accessible with in the assembly.
So my question is what is the basic bifference between them.
Thanks and regards

internal means accessible only to other classes within the assembly.
internal protected means accessible only to derived classes within the assembly. No other classes (even within the assembly) can access something marked as internal protected.

You sure about that? MSDN says[^] that internal protected grants access to classes that are within the same assembly or derived from the base class (even in external assemblies).

Oops! You're right. I must have misread that and thought that both conditions had to be satisfied. I stand corrected.

I'm sorry , your not clear at all. By Form do you mean the Form code thats in the General.cs file!?  thats a little odd, you would have to compile the .cs file and then run the .exe! But why would you want to do that!??

Try out this......................
// Connection String.
String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + FilePath + ";Extended Properties=Excel 8.0;";
// Create connection object by using the preceding connection string.
con = new OleDbConnection(connString);
// Open connection with the database.
con.Open();
// Get the data table containg the schema guid.
dt = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
if(dt == null)
{
return null;
}
string[] excelSheets = new String[dt.Rows.Count];
int i = 0;
// Add the sheet name to the string array.
foreach(DataRow row in dt.Rows)
{
excelSheets[i] = row["TABLE_NAME"].ToString();
i++;
if(i==sheetNumber)
break;
}
OleDbCommand excelCommand = new OleDbCommand("Select * from ["+excelSheets[sheetNumber-1]+"]",con);
OleDbDataAdapter excelAdapter = new OleDbDataAdapter(excelCommand);
System.Data.DataTable importStudentsDT = new System.Data.DataTable();
excelAdapter.Fill(importStudentsDT);
return importStudentsDT;

private string CurrentPath = Environment.CurrentDirectory.ToString();
But watch out when using FileDialoges, it can give you the directory of the file/directory you choose.
