I am using Microsoft Visual Studio 2010
|
|
|
|
|
And what is the relevance of that? You do realise that Visual Studio is a development environment and not a programming language?

Be cource the errorcodes I got was from MS Visual C++ 2010.
I thought it might explain to you why I got thoose errorcodes in C++.
Its C++ I am Using.

This is the C++/CLI forum; which are you using, C++/CLI or unmanaged C++?

Seriously? You are writing a program and you do not know what language or framework you are using? I don't know how you expect us to help if you cannot answer such a basic question. I would suggest you make a decision which language you plan to use and get hold of a book to learn the basics of it before trying anything else.

Thanks for the help.
But i gotta say, I feel it a is waste of time to try and get anything usefull out of you.
All I ask for, is that you write one line of code with my own data in C++. But instead i feel you blame me for not knowing anything, even though that was one of the first things i told you.
I will try my luck some other time.

No, you have not asked that, you asked how to get a number formatted in a particular way in C++/CLI, and I referred you to the documentation that explains it in detail, with plenty of samples. It seems you are not prepared to spend the time reading it. You also do not seem to know exactly which language you are using, so I cannot answer the question, because it would be different for each language.

Neither did I blame you for anything. I have done my best to help you but I cannot answer the question unless I get the proper facts to start with. As I said before, you need to decide which version of the language you are using and start studying it. Give us the proper facts and background to your problem and we will try to help, but you are expected to do some of the work for yourself.

1 - convert them to float type , example :
{
double a = 2.1589687489;
String^ b = Convert::ToString((float)a);
}
2 - remove them , example :
{
double a = 2.1589687489;
String^ b = Convert::ToString(a);
b = b->remove(b->IndexOf('.')+2 );
}

There is no need to do that when you can use format strings to produce the required result in the first place.

So? That is no reason to rudely post this over and over.

ok i see ur disturbing... im sorry. nobody born with c++ LANGUAGE knowledge.. u too, like me was amateur....

Okaaaaaaaaaaaay what exactly does that have to do with anything? Knowing C++ is not a prerequisite to following the forum posting guidelines or for having some manners.

i dont see any tutorial for c++ windows form???? please help

You will have to look at the C# and VB.NET samples and adapt your code from them, as they all use the same .NET framework.

I Get this error, when I write a number in my textBox1, and then erase it again.. Then this popup appers:
An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll
Additional information: Input string was not in a correct format.
Code:
private: System::Void textBox1_TextChanged(System::Object^ sender, System::EventArgs^ e) {
double tysk, ti, femten, tyve, dansk;
tysk = System::Convert::ToDouble(textBox1->Text);
dansk = tysk * 7.5;
ti = tysk * 7.5 * 0.90;
femten = tysk * 7.5 * 0.85;
tyve = tysk * 7.5* 0.80;
label7->Text = System::Convert::ToString(dansk);
label8->Text = System::Convert::ToString(ti);
label9->Text = System::Convert::ToString(femten);
label10->Text = System::Convert::ToString(tyve);
}
};
It also appers when I type a letter in the teksBox1.
Otherwise it workd fine.
Its just a simlpe calculator.

tysk = System::Convert::ToDouble(textBox1->Text);
This will always throw an exception if the contents of teksBox1 is not a number. You should either catch the exception and deal with it, or use the TryParse[^] method.

Look this Example .. it will help.
int a= Convert::ToInt32(this->textBox1->Text->Trim());
int b= Convert::ToInt32(this->textBox2->Text->Trim());
int sum=a+b;
"The more quieter you become, the more you are able to hear..."

Use this instead of "Convert::ToString()" function
int a = 287;
String ^b = "";
b += a;
