Call a fucntion belongs to one form from another

What have you tried ? What do you understand about how threads work ? Why do you want to use them ?

I tried this Simple Database Application - Part 1
using thread allows access to the database by several users at the same time and perform all processing updates on the database (identification, addition, modification, consultation, delete, printing ..) and memory management.

Hi everybody,
I have two form, in the first one I fill some data, then I open another form, fill some more data, and now I need to Call a function from the first form, using the data filled in the first form and pass the data from the second.

What is the best way to do that ?

Delegates are the ONLY real way to do that.

Hi,
I have two parameters as follows:
string scriptText = MsgBox "hello";
string MachineName = "targetMachineName"

I would like to create a file called sample.vbs which will have the scriptText in it.
This file will have to be saved in the c directory of the MachineName.

How is this done please?
Thanks

File.WriteAllText ?

What have you tried ? What is the target machine, is it on your network, and if not, how is it your target ?

I think this is to do with the streamwriter or something similar.
Target machine is any machine on the network.
Thanks

File.WriteAllText with a network path, if you have access to the machine. If you don't, then you don't, no matter what.

I want make a program Dictionary, i use one table have 3 two field: words, mean and pronoun. Please tell me the way. thank you very much! Big Grin | :-D

Well, you could read this[^].

Apart from that, if you have your table layout, the next thing you need is typing. Lots, and lots of typing.

What answer were you hoping for ?

You could maybe use a dictionary, using the word as the key and a definition class instance as value?

Something like:

public class Definition
{
    public Definition(string meaning, string pronoun)
    {
        Meaning = meaning;
        Pronoun = pronoun;
    }
    public string Meaning { get; private set; }
    public string Pronoun { get; private set; }
}

Dictionary<string, Definition> definitions = new Dictionary<string, Definition>();
public void AddDefinition(string word, string meaning, string pronoun)
{
    definitions.Add(word, new Definition(meaning, pronoun));
}
// other methods here...

you can use .netframwork generics or extended generices called powercollection.

int.Parse() and Converter.toInt()

we know that there are at least two ways to convert a string to a number, let's say, int:

int.Parse('100')

convert.toInt32('100')

I also read from one book that Convert is at cost of some performance. why? does it mean that it is better to use .Parse() instead of using Convert?

thanks!

If one were "better" than the other, one of both would be obsolete Smile | :)

If the value you're converting is NULL then Parse[^] will throw an exception, while ToInt32[^] sets it to the number "0".

OK, I agree your comments,but I concern mainly that which one is more performance efficient, espeically when such function is
used lot of times.

Christian Graus8-Jun-09 23:55

You should really only ever use TryParse unless you're *certain* there's a number in there. Both operations are costly, they both involve parsing the string and turning it into a number.
