You can't have array of functions. You can have array of delegates referring to function. It would be like

delegate void Function();      
Function[] functions = { Function1 , Function2 , Function3 .. };
functions[0](); // calling 1st function

Heh, you could write some fun code with that:

FunctionDelegate[] functions = null;
functions = new FunctionDelegate[]{
    delegate(){
        functions[0]();
    }
};
functions[0]();

Dynamically change method

If I have multiple vendors which I make classes to get data for vendors X,Y, and Z, and I ask for data N,M,and O. How can I dynamically change the method so that I may continually add vendors without having to constantly change the code in other parts of my program. I want to be able to choose the vendor and
data from a ComboBox, so when I make the choice it will change the method as follows. If not this way is there another way I can accomplish the same goal.

GetMfromVendorY()
GetNfromVendorX()
GetOfromVendorY()
GetMfromVendorZ()

Thanks in advance,
Michael

Instead of having different methods why don't you use Generics..I mean have a common method which takes a Generic param i.e. the Vendor type you want to access...

Not sure I got your question correctly.

You define a interface something like

interface IVendor
{
    M GetM();
    N GetN();
    O GetO();
}

Now each of your vendor classes has to implement this interface. Maintain a configuration file where class names of all these vendors are stored. According to the dropdown value, get the relevant class name from configuration and invoke it using reflection. You can use Activator.CreateInstance[^] for this. Cast this object as IVendor and return. Now you can call required methods on this.

This will help you to add new vendors without recompiling the program.

Hi,

did you pay attention to all of the settings described in the sample? Do you get an error message when you try to run the sample? What is the error message saying?

Since the sample has something to do with security I assume it is a security issue. Have a look to the Windows Event Viewer, there should be an exact description of the error. Post this error here, so that we can have a look at.

changing mac address

Hello. Did anyone try to change his mac address,and achieve it? I can change it by using network adapter properties. And when looking its value with ipconfig/all command, it shows the value that i changed. But in this case it dosent connect any wireless networks. Later i learned that some registry keys are hold by windows. that is to say it was not enough to change the value from properties screen, also should have been changed registry. I found a program written with c++ but it didnt work again. Now, did anyone use that kind of program or write in c#. Or is it impossible?

char[] delimiters = { ',', '#', ';', ' ', '/', '\0', '&', '-' };
strTemp = a[i].Split(delimiters, StringSplitOptions.RemoveEmptyEntries);

#69;xx street;yy city(input)

given the above input, it should split based on the delimiter... the above code removes the delimiter...but the delimiters should be retained...
is there any method to do this...
thanks in advance

You could go through the result, appending the delimiter. Of course, you'd have to use the delimiters one by one.

Or write your own method. Regex may work as well, not totally sure.

Hi there,
I was wonder if it is possible to send data from the computer to the mobile via C# program that make a Bluetooth connection to that mobile

in other word the computer (my application run on the computer), scan from enabled blue tooth devices then send to one of the device msg, and the the mobile can send back another msg,

if that is possible could the application on the mobile be in different language such java 2ME while the application running on the computer be C#,

please, if you just can give me a hint so I can start right , or some links that can help

thanks

I don't believe any bluetooth library exists in .NET, so you'd need to buy one.

DataGridView

I have a DataGridView with many DataGridViewTextBoxColumn(s). As soon as the value is changed within the cell I want to send it to my object--not once the cell loses focus--how can I do this? I tried to cast it to a textbox and created an event handler for TextBox's TextChanged event but the problem is I need the column and row info which you normally access through e.ColumnIndex and e.RowIndex of CellEndEdit and other events. Any ideas?

One thing I can do is on CellEnter I can grab the column number and row number and save it in a variable and use it later but is there an alternative? I need realtime event like the textbox's TextChanged event.
