Managed C++/CLI

2beeIn addition i would like to point out, that it would be more secure to use parameters when constructing dynamic SQL statements.

<br />
extern "C" void __declspec(dllimport) extiteratie( [arguments] )<br />

<br />
TFortranInterface.cpp(27) : warning C4272: 'extiteratie' : is marked __declspec(dllimport); must specify native calling convention when importing a function.<br />

<br />
 error LNK2031: unable to generate p/invoke for "extern "C" void __clrcall extiteratie( float*, float*, (...) float* )" (?extiteratie@@$$J0YMXPAM000000000000000PAH110@Z); calling convention missing in metadata<br />

<br />
extern "C" void __cdecl extiteratie( [arguments] )

My C++ brain tells me that I would like to simply use a for_each, like this:

using namespace System;
using namespace System::Collections;

int main(array<System::String ^> ^args)
{
	String ^s = gcnew String("Hello, I am a test String");
	array <Char> ^sChars = s->ToCharArray();
	IEnumerator ^myEnum = sChars->GetEnumerator();
	while (myEnum->MoveNext())
	{
		String ^ss = (myEnum->Current->ToString());
		Console::WriteLine("-{0}-", ss);
	}
    return 0;
}

<br />
private: System::Void outputToScreen()<br />
{<br />
<br />
}<br />

<br />
private: System::Void outputToScreen(array ^args)<br />
{<br />
}<br />

Thanks for your help, but I'm afraid that I need a little more guidance

First the answer to your question: I am using .NET 2003.

Some syntax diffrences betwen VS2003 and VS2005 (List is incomplete
VS2003						VS2005
new						gcnew
__gc						(In gc container, you don't use it)
* (pointer def.)				^
(String *sArray = new String __gc *[10];	array (defin. for ar.)

Straight away I am slightly lost with your sample code, how can I take your suggested code and import it into the code that .NET has produced for me. Bearing in mind I am not within the main method but within a new that I have created.

richTextBox1->Text = "Hello, World.";	// Displays Text
richTextBox1->Select(7,5);	// Select Chars, Starting in 7th pos. and 5 chars
richTextBox1->SelectionFont = new System::Drawing::Font("Tahoma", 12, FontStyle::Bold);	// Set Font Name, size and style
richTextBox1->SelectionColor = System::Drawing::Color::Blue;	// Set a color.
richTextBox1->DeselectAll();	// deselect a sellection

The trouble is I can't seem to get to grips with the .NET framework, I find it harder than good old C++.

<br />

{<br />
  //Must clear the contents of the textBox for each repaint<br />
  textBox->Clear();<br />
<br />
  //New temp string for use within while loop<br />
  System::String *temp_text_string;<br />
				<br />
  //Initialise text_string<br />
  text_string = S"Hello I am a test string";<br />
				<br />
  //Declare an array, call it stringArray<br />
  Array *stringArray;<br />
 <br />
  //Fill stringArray with contents of text_string<br />
  stringArray = text_string->ToCharArray();<br />
<br />
  //Not sure what this does<br />
  IEnumerator *myEnum = stringArray->GetEnumerator();<br />
<br />
  //Loop through myEnum<br />
  while (myEnum->MoveNext())<br />
  {<br />
    //Initialise new_text_string with current value<br />
    temp_text_string = (myEnum->Current->ToString());<br />
		<br />
    //Setup up the font (currently the same for all chars - need to create another array)<br />
    textBox->SelectionFont = new System::Drawing::Font( "Arial",12,FontStyle::Italic );<br />
<br />
    //Output to richTextBox ("textBox")<br />
    textBox->SelectedText = temp_text_string;<br />
  }										<br />
