Ok thanks guys
I'm still not sure I quite understand what the hell static is doing, but dropping it doesn't seem to have affected anything else in my program (The above was just a sample so I didn't have to post 1000s of lines)
Thanks again for the quick reply. I was getting ready to start breaking stuff... you guys have probably saved my monitor lol.

What does static do? Well, it is kinda important.
If you define the following:
public class Demo
{
public static string s1 = "Hello";
public string s2 = "Goodbye";
}
When you define a class, only the parts of the definition that are marked as static exist. So, if your code consists of:
static void Main()
{
Console.WriteLine(Demo.s1);
}
then it works, because s1 always exists as part of the Demo class.
But you can't have:
static void Main()
{
Console.WriteLine(Demo.s2);
}
because s2 only exists when you create an instance of the Demo class. Thus:
static void Main()
{
Demo d = new Demo();
Console.WriteLine(d.s2);
}
Will work. "d" is given a new instance of the Demo class, and so it has a "s2". If you create a second instance of Demo
Demo d2 = new Demo();
then d2.s2 will also exist, but this does not have to be the same as d.s2 They are separate instances.
Try to think of it this way: you can have two instances of a car - your car, and my car - and they are separate. If I crash my car into a tree, it does not affect your car. If neither of us have a car, then Ford (the car manufacturer) still exists.
"Ford" is static, it exists with or without an instance of car, but to get to the shops, I must have an instance of car for myself.

Ahh ok that makes sense now.
I think it was just the error message that was driving me insane.
It's terriable... I'm so good at writing programs and have been doing it for years, but still don't know the 'basics' lol

No problem - I know the feeling well!

Hi all,
i want to know how to fire enter key press in the textbox to log into next form or to move fouce on the button
Thanks
|
|
|
|
|
Just use the event "KeyPress" or "KeyDown". Check if key pressed is "Enter".
If "Enter" pressed, then button.Focus(); or go to next form.
|
|
|
|
|
Use something like this....
private void Textbox__KeyDown( object sender_, KeyEventArgs args_ )
{
if ( args_.KeyCode == Keys.Return )
{
// Do whatever
}
}

Hi All,
I have tables called CALL and Operator.

Group by Mobile
What i want is to get the first date of entry for each Mobiles in the month of april and the operator who attended them.
However i Have to group by Name_operator to run the above script.But i dont want them to be grouped by OPerator.I want the first entry of a mobile in the database together with the name of the operator who attended them.
How do i go about it Please?

You can add to the SelectedItems collection.

for(int i = 0; i < listView1.items.count; i++)
listView1.setSelected(i,true);
Use the above loop to select each item.

Did you look at the first hit on the list - a complete method for drag/drop between trees. What do you expect from the forums.
I actually tried the search, recognised some of the links that I used when playing with this when I moved from VB to C# recently and figured it was an excellent place to start. If you cannot get anything useful from that list then you have my sincere sympathies as you must be in the wrong career.

well if ud read my first post ud see that it does work the whole drag nd drop, its just tht i found a bug that it doesnt take the underlying nodes with.
there is nothing wrong with asking for help. it can turn out be timesaving when u dont have a lot of it.
|
|
|
|
|
Well, it sounds like your code doesn't go into the child nodes of the dragged node and moves them as well. So far, your code only moves the one node.

I want to store dynamic variables in a exe file (C#), that I can access [mostly just strings] to read or write. I was using the Application Settings class but it apparently saves the files in Application Data but I want my exe to take the values from the form and write them to itself or store them inside the executable file so that when I send the file to someone else it will have the preferences stored without having to do anything.
If this is not possible is there any way of making a C# builder application that will ask for variables and then create a new exe file with the variables pre-stored? Thanks

Take a look at this thread[^], it may help

You're much better off keeping those values in a seperate file. You cannot write to an .EXE file that is still running.
Not to mention the problems with finding the values in the binary file and CAREFULLY writing the news back so you don't screw up anything around it.

Hi there,
thanx for taking interest in my question. Please suggest me some sites where I can submit my software with some gains..... And is the EULA predefined during the time of creating the setup for the software? Or will I have to submit the entire Solution to the software dealers without creating any EULA or setup?
Please help,
