Well it does not appear that you are. What you are doing is posting questions one at a time and asking someone here to write the code for you. Studying means actually sitting down with a book, online tutorial etc and working through it until you understand it. The fact that you don't understand arrays suggests you have a long way to go.

Interesting. So are you looking for a syntax of writing managed arrays? Here is how you write a simple integer array.
array<int>^ arr = gcnew array<int>(2);
arr[0] = 26;
arr[1] = 18; Fenix2 wrote: How do I write a variable in a damn file??!
Here is how you write array of strings to a file.
using namespace System;
using namespace System::IO;
typedef array<String^> StringArray;
void WriteArrayToFile(StringArray^ arr)
{
StreamWriter writer("c:\\test.txt", false);
for each(String^ str in arr)
{
writer.WriteLine(str);
}
}Use it like:
StringArray^ arr = gcnew StringArray(2);
arr[0] = "You need";
arr[1] = "a good book";
WriteArrayToFile(arr); All I can say is, grow up, read the posting guidelines and post your question nicely with relevant code and change your attitude if you expect help from this forums.
If you ever plan to read a book, try this[^]

Niice
this will probably help me...
I gotta try it...
I'm 22 years old, I don't have money to spend on books... there are poor people on canada and managin to get a 2300$ computer 3 years ago made me full of school loans. (Lol...)

Do you have a library near you where you could borrow one?
Even if not, you obviously have access to the internet and there are thousands of good tutorials around, just try searching this site and use google. That's what the rest of us have to do.

HI all,
I am getting this error since morning, I am clue less as I am working first time on it (I am c# developer).
the code file are as follows and i compied using Commnad prompt
command cl /clr:oldSyntax DemoCPP.cpp
DemoCPP.cpp class
#include "DemoHeader.h"
DemoCPP::DemoCPP()
: Length(0.00), Height(0.00)
{
}
DemoCPP::DemoCPP(double L, double H)
: Length(L), Height(H)
{
}
DemoCPP::~DemoCPP()
{
}
double DemoCPP::getLength()
{
return Length;
}
void DemoCPP::setLength(double L)
{
Length = L;
}
double DemoCPP::getHeight()
{
return Height;
}
void DemoCPP::setHeight(double H)
{
Height = H;
}
void DemoCPP::setDimensions(double L, double H)
{
setLength(L);
setHeight(H);
}
double DemoCPP::Perimeter()
{
return 2 * (Length + Height);
}
double DemoCPP::Area()
{
return Length * Height;
}
header file DemoHeader.h
#pragma once
#using <mscorlib.dll>
__gc class DemoCPP
{
public:
DemoCPP();
DemoCPP(double L, double H);
~DemoCPP();
double getLength();
void setLength(double L);
double getHeight();
void setHeight(double H);
void setDimensions(double L, double H);
double Perimeter();
double Area();
private:
double Length;
double Height;
};
any body have any idea how to resolve this problem?
thanks in advance!

Since this is a DLL, you need to compile with /DLL compiler switch. BTW, why are you using old syntax?
|
|
|
|
|
Thanks for quick response!
Yes I have googled a lot and then placed question here...
the Old command i am using because it is recommended by the VS2005 when i tried to build the project from vs2005
I tried the project type as empty project as well as class library!
still I am getting the same error!
I have created the project using wizard itself!
any further help!
thanks in advance!

If you have VS, don't do command compilation. I never came across a situation where VS recommended old syntax. If you need to create a fully managed assembly, choose Class Library project type. Use new syntax and compile using /clr:safe.
if you need to communicate with native libraries, compile with /clr switch which will produce mixed assemblies. Since you have VS IDE, best option is to use it to compile rather than doing through command. VS does things like manifest embedding automatically.

thanks navneeth for ypur reply
I tried using /clr:safe option however i got the following error
Error 1 error C4980: '__gc' : use of this keyword requires /clr:oldSyntax command line option d:\excercise\dot net\cppclasslibrary\cppclasslibrary\CPPCLassLibrary.h 8
so as suggested I used the /clr:oldSyntax
and option _gc I am using as i want to consume this class libray in c#

Here is your class using new syntax.
#pragma once
using namespace System;
ref class DemoCPP
{
public:
DemoCPP();
DemoCPP(double L, double H);
~DemoCPP();
double getLength();
void setLength(double L);
double getHeight();
void setHeight(double H);
void setDimensions(double L, double H);
double Perimeter();
double Area();
private:
double Length;
double Height;
};Now compile using /clr or /clr:safe.

I got the Answer
here it is
1. Project Properties -> General Tab
2. for Common Language Runtime Support select Old Syntax (/clr:oldSyntax) from drop down
now you do not need to play with command line .....
you can easily build your project from visual studio IDE itself

Here's some code :
private: System::Void TS11_MCli(System::Object^ sender, System::Windows::Forms::MouseEventArgs^ e) {
Tsn11 = Tsn11 + 1 ;
if (Tsn11 = 0) { this->TS11->Image = Image::FromFile("C:/GamePics/NOTILE.png");}
else {
if (Tsn11 = 1){ this->TS11->Image = Image::FromFile("C:/GamePics/GREEN.png");}
else {
if (Tsn11 = 2){ this->TS11->Image = Image::FromFile("C:/GamePics/GRTRE.png");}
else {
if (Tsn11 = 3){ this->TS11->Image = Image::FromFile("C:/GamePics/ROAD.png");}
else {
if (Tsn11 = 4){ this->TS11->Image = Image::FromFile("C:/GamePics/WALL.png");}
};
};
};
};
};
};
};

Your questions is not clear. Please explain it clearly.
Also the code posted is less readable. Please remove unnecessary spaces and format it nicely. I think a switch case makes more sense here than nested if.

The question is ultra simple.
How do I get a mouseclick event work twice?!?
As for the code, it works.
The bug is either the variable won't increment more than once, either the procedure is usable only once.
I'm gonna try something.

Maybe to you!

Obviously it doesn't, or you would not be asking this question.

I would suggest you start with your if (Tsn11 = x) statements.

Funny. I haven't noticed if (Tsn11 = x).

Hi,
in C/C++/Java/C# the equality operator is ==
Tsn11 = 1 is an expression which both sets Tsn11 to 1 and evaluates to 1, so your if statements will not act as you expect.
FWIW: in VB/VB.NET the equality operator is =

So where are you suggesting to put ==?
at the IF statement, or at the increment?

It doesn't work.
If I guess,
I'd say myself that the error is in the starting of the form.h
What if the variables are always reset to 0?
What if the form, would be... in a repeatative process?
So where should I put the variable Tsn11 ?

Fenix2 wrote: It doesn't work.
What doesn't work?
You have statements of the form if (Tsn11 = 0), which, as Luc pointed out are incorrect. The equality operator in C++ is ==. Correct all your if statements and see what happens.

Yeah Thanks to all of you.
It works now.

Whats a natural successor to the COM object in the managed C++/CLI world?
I am migrating an app which has COM objects for no better reason that than is the only way I could get a form into a DLL to share between two exe's.
What should I be using in C++/CLI?
