c++ code in c++/cli (visual c++) project

Question

13 Years Ago

I've heared that its very easy to add c++ code to c++/cli project (net.framework @ Visual Studio 2010)
Unfortunatelly I cant do that.
I was seraching all over the internet and I cant find any decent examples.

All I want to do is to make a function that will read all options sfrom config/config.txt file, and to show them in the checkbox item....
my previous program was written in pure c++ and i made function which read all option sfrom the text file...and it was sth like this:

void system_load()
{
      int counter=0;
      int counter1=0;
      string filename,filename1,line;
      filename="CONFIG//systems.txt";
      ifstream plik_wejsciowy (filename.c_str());
      if (plik_wejsciowy.is_open())
      while (! plik_wejsciowy.eof() )
            {
            counter++;
            getline (plik_wejsciowy,line);
            if (line == "") continue;
            comboBox1->Items->Add(line);
            }
 //---------------------------------------
	  filename1="CONFIG//affected.txt";
      ifstream plik_wejsciowy1 (filename1.c_str());
      if (plik_wejsciowy1.is_open())
      while (! plik_wejsciowy1.eof() )
            {
            counter1++;
            getline (plik_wejsciowy1,line);
            if (line == "") continue;
			comboBox2->Items->Add(line);
            }
 }

I have tried to rewrite it to load options from text file into the ComboBox1 but without result...when i add that void to the code below (form1.h) I recive thousands of errors...as if it was not written in c++..
I added new namesapce std etd...it didnt help..ofcourse I added also all "includes" to the code, but it generated some linker errors..thats all.

If your C++ code consists of functions in a header file, then include the header file in the form you wish to use it in, and call the functions.

If your C++ code consists of class/es in a header file, then include the header
file and use the class.

I don't know why, but often times C++/CLI forces me to use dynamic memory allocation for classes:

class myclass
{
 int i;
};

//....
//in C++/CLI code:
myclass *m = new myclass();
//..use 'm'
delete m;

Check your compiler settings and make sure that /clr:pure is not set.

Edit: but you probably still need the plain /clr switch since you have the managed code in there

/clr:pure isnt set (have changed it to (/clr)
Now i recive linker errors like:

I'm always a bit confused by the interaction of the managed and unmnanaged code. I think pointers are still one of those dicey areas at that interface. When you're compiling under /clr:pure, it's mandatory to use the "marshalas" functions to shuttle data from one side to the other. When you relax the /clr level, I thought that the two sets of code were more cooperative, but that may not be the case. This is something I'd have to look up.

I will have to investigate that problem too..
Unfortunatelly I have program written in c++ ..All I need is to add only a windows GUI interface..its very easy to do in VC++..but the rest is more complicated...
especially adding my c++ voids to the proggy.
I have managed to write that load config void in visual c++
But I think it will be pain in the ass (for me) to rewrite everything.
Visual C++ (cli/c++) has way less examples than pure c++...I cannot find any...
But maybe with help of this forum I will be able to rewrite it?
its very easy program..it will replace some key words in html file...with the text typed in GUI interface...
so probably I will need to rewrite sth like that too:

void FindAndReplace( std::string& tInput, std::string tFind, std::string tReplace ) 
{ 
     size_t uPos = 0; 
     size_t uFindLen = tFind.length(); 
     size_t uReplaceLen = tReplace.length();
if( uFindLen == 0 )
{
   return;
}

for( ;(uPos = tInput.find( tFind, uPos )) != std::string::npos; )
{
    tInput.replace( uPos, uFindLen, tReplace );
    uPos += uReplaceLen;
}

}

this code replace the word by the other word.
Program will read html file..if it will meet SYSTEM text in it..It will replace it with the text i want (taken from the text field in form)
