static public void ToFile<t>(T[] vec, string name) where T : IEnumerable<t>
{
using (StreamWriter sw = new StreamWriter(name))
{
foreach (T v in vec)
sw.WriteLine("{0}", v);
}
}
Now to call that function with:
double[] vec = { ...some numbers ... };
ToFile.(vec, "filename.txt"); <---- error double[] sould be IEnumerable

You can't do that. You've constrained T to be enumerable, but T in your example is double and not an array of doubles.
|
|
|
|
|
it is ... T[] vec ... if this is what you meant.
How to do it any way?

Well, in your example, the compiler will map to double, and that will break the T:IEnumerable constraint. I guess you simply want the first parameter to be enumerable, in which case,
static public void ToFile(T vec,string name) where T : IEnumerable
{}
will work. Or, if you want to ensure that the caller passes an array of T, you could do away with the constraint, arrays are always enumerable.

I need to use the code like:
int[] vec1 = ...
double[] vec2 = ...
etc...
ToFile(vec1, "file1.txt");
ToFile(vec2, "file2.txt");
If you remove 'where T : IEnumerable' the foreach statement will not compile, if you keep 'where ...' the ToFile(vec, "filename") will not compile
Would you provide here your modification of ToFile() that compiles along with its invocation with vec1, vec2, etc...

Huh? Did you actually try removing the constraint? This code compiles fine on VS 2005.
static void ToFile<T>(T[] t, string name)
{
foreach (T val in t)
{
}
}
static void Main()
{
int[] intArray = { };
double[] dArray = { };
ToFile(intArray, "a");
ToFile(dArray, "a");
}

I am using Outlook 2003 and i want to make my own add in components to Outlook. So in my application, when i click a button, I want to be able to display the outlook address book and be able to select the contacts from the Address book and populate those selected names in my add in component.
How do I achieve the same?
Thank you

Hi All,
There is the requirement to read Excel file and store data in a datatable for my web project. I am using C# language.
My code is written below
String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";
objConn = new OleDbConnection(connString);
objConn.Open();
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [" + excelSheetName.Trim() + "]", objConn);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
objAdapter1.SelectCommand = objCmdSelect;
objAdapter1.Fill(dt);
The above code returns data to a data table, but the problem is to read formated Excel sheet. Suppose there is a formula field, it doesn't store the actual value. It stores some different value.
What other method to read the excel file? I am not using COM component of Excel to read as it is a web project. There may be a security problem after deployment. 
Thanks in Advance.

You may want to look around on Oracle's site or ask this in the SQL forum.

Don't cross post the same question in multiple forums. It make's collaboration on an answer just about impossible.

You shouldn't cross post messages. It's considered rude - see forum guideline no.1.
Choose the most appropriate forum for your question and post there only. As this is an ASP.NET question, the ASP.NET forum is more appropriate.

Hi!
I created a new Windows Service in C# and want to set a Service Dependency.
Did it like this:
ServiceInstaller si = new ServiceInstaller();<br />
si.ServicesDependedOn = new string[] { "DependingOnThisService" };<br />
this.Installers.Add(si);<br />
Everything works fine. My Problem right now is, that I want to set this Dependency only in fact of a special "flag" in the app.config - file.
But I am not able to read from the app.config - file in the ( from System.Configuration.Install.Installer inherited) class.
I neither get an exception nor a result from the config - file (always get an empty string).
So is there a possibility to read from the app.config in this class or, if not, what is the best alternative to do this?
Hope anybody can help me!

I am using VS 2003 with 1.1 of the framework. (No hope of getting an upgrade )
Scenario
I am using a textbox which allows a user to input text in order to filter a list. I am using the KeyPress event for the control to save the user from having to click a separate button.
Problem
The event doesn't fire sometimes. The odd time another control (e.g. a button ) gains focus and fires it's Click event.
I have tried searching this site as well as Google to no avail.
Has anyone encountered this type of problem?

Other controls should only get activated if they have some kind of shortcut via alt or if they are the accept/cancel buttons (enter / esc). It might be worth checking the keypreview property of your form is set to false.
|
|
|
|
|
You might want to make sure the Form's KeyPreview Property is set to true. Getting the property information from the object browser for the property:
<quote>Gets or sets a value indicating whether the form will receive key events before the event is passed to the control that has focus.
