I suspect that means you need a great level of accuracy than C# offers. Are you using the floats, Decimals or doubles ? You may need a scientific library of some sort.

Well, the probability that I get values less than E-999 or greater than E+999 is more or less zero, but I thought that it would be cleaner if I could handle both positive and negative values with one format string.
I use doubles, but thats not carved in stone...

hi dudes,
i have a c# solution(windows application),when i want to deploy my project,it gathers all the application resources and needed files into one exe file named setup.exe,but the problem is that i dont want to install my application on the destination computer,i just want to run it quickly without installation,and the .net framework is already installed on the destination computer .how can i make one single exe file executable on the destination system?i dont have any problem if i have to seprate it from needed files like my access database.
i will be thankful if any of u guys can help me.

if it's .NET, you should be able to put it on a memory stick and run it from there.

This is simply xcopy deployment. Just copy the files from your \bin\Release directory to a folder on the other machine, and voilà!

hello all
i have troubles with the following code
there are two forms
Form1 and Form2
Form1 is the owner of Form2
i need to move label1.text from Form2 to Form1 (note: both forms are running and visible)
here is my code
Form1 F1 = (Form1 )this.Owner;
F1.textbox1.text = label1.Text; // i had set textbox1 modifier property to public
thanks in advance

This should work, although it's probably the nastiest code I've seen today ( and that's huge ).
1 - why on earth can't anyone here give their variables meaningful names ? Form1 ? Label1 ? Are you all REALLY comfortable with that ?
2 - making your controls public is retarded. If you must, make a string property public that sets the text on the label, but don't expose the whole thing. If your doctor asks to see the back of your knee, do you take all your clothes off ?
3 - you say 'I have troubles' then you post code that looks like it should work. What troubles ? What's happening ? Does it run ? Does it blow up ? If you want to ask a question, you need to be CLEAR
4 - the best way to communicate between forms is delegates. Then no properties need to be exposed.

Depends on the doctor.

thanks Christian ..
but i am still suffering
error null reference exception was unhandled
|
|
|
|

What line gives you the error ? Did you change your code completely to get rid of all the stuff I said was retarded and use delegates ?

F1.textbox1.text = label1.Text;

Well, it would help if you knew what you were doing. I assume you have no idea what object is null ? Do you have any idea how to use the debugger ? Hit F9 with the focus on this line to set a breakpoint, hit F5 to debug and when the code stops on this line, you can hover over each object. Either F1 is null ( which seems unlikely as you cast it and don't use 'as' ), label1 is null ( unlikely as it's a local object ) or textbox1 is null. Once you work out which is null, you can work out why. Do you set the Owner of the form when you create it ? That may be the problem.

Why ? This is surely not code that someone is going to use in real life ? It's a disaster, as I said.

thanks Christian
i found where the error is
i forget that f1 have mdiparent to another form
but i want to know why i can`t set mdiparent and owner at the same time?
|
|
|
|
|
Because the owner exists entirely to create a relationship in terms of how the form is shown, and it's invalid if it's got an MDIparent instead.

where you wrote this code?? under form1 or under form2?
what you really want do?please describe in details...
|

dude i think ur trying to move a string(lable1.text) from form1 to form2,it's easy.
for example u want have a button,when clicked u want to show second form.
form2 f2=new form2();
ok,now goto ur form2.cs code view,in the first lines u c something like this:
public form2()
{
initializecomponent();
}
now change the arguments that form2 needs,in the code above,u c that second form doesn need anything for being instanced,change it like this:
public form2(string labltext)
{
...
}
now when u want to make an instance of the second form,pass the string in that way:
form2 f2=new form2(label1.text)
in second form u can access the string throw variable labltext.
have fun ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

in my project, i need Serial No like 1, 2, 3, in sequence in date wise
for Example today is 28/10/2009......so the serial no should be like 1.2.3
and when the date changes it must start again 1.2.3
any idea ?
thanks for help

You don't mention what your data store is. ASsuming a SQL DB, the resetting numbers mean you can't use an identity column, you probably just have to write code to work out the next value for the current date.

It's your business rule, but I think you described it correctly, yes.
