Thread: write to txt file

Hi,

I am trying to write info to a txt file.

All I am getting in the txt file is message.

Code:

// include files nedeed by our code.
#include <plugin.h>
#include <stdio.h>
#include <lib/gui/ewindow.h>
#include <lib/gui/elabel.h>
#include <lib/gui/ebutton.h>
#include <lib/gui/emessage.h>
#include <lib/gui/textinput.h>


// The Class declaration of our Main Window
class eBibleMainWindow: public eWindow
{
	// the label to show the text
	eLabel *label;
    // the textinput
	eTextInputField *mytext;
	eTextInputField *mytext1;
	eTextInputField *mytext2;
	eTextInputField *mytext3;
	eTextInputField *mytext4;
	eTextInputField *mytext5;
	eTextInputField *mytext6;
	eTextInputField *mytext7;
	// function to execute when button is pushed
	void message1();
	
public:
		// the constructor.
	eBibleMainWindow();
		// the destructor.
	~eBibleMainWindow();
};


// The plugin entry point, Here start the code execution
extern "C" int plugin_exec( PluginParam *par )
{
	// our demo dialog instance.
	eBibleMainWindow dlg;
		// show the dialog...
	dlg.show();
		// give control to dialog.. (the dialog is modal!)
	int result=dlg.exec();
		// and after it, hide it again.
	dlg.hide();
	return result;
}


eBibleMainWindow::eBibleMainWindow(): eWindow(1)
{
		// move our dialog to 100.100...
	cmove(ePoint(100, 100));
		// ...and give x and y dimensions.
	cresize(eSize(550, 376));
		// set a title.
	setText("!!EDITOR!!");

	// create a label to show a text.
	label=new eLabel(this);
	// give a position
	label->move(ePoint(20, 50));
	// set the label dimensions
	label->resize(eSize(400, 100));
	// set the label text
	label->setText("Enter Here.");

	// create textinput
	mytext=new eTextInputField(this);
	// give position
	mytext->move(ePoint(20, 100));
	// give size
	mytext->resize(eSize(25, 40));
	// set max number of characters
	mytext->setMaxChars(1);
	//mytext->setUseableChars("1234567890");
	//mytext->setText(codeentry);
	// show a frame decoration
	mytext->loadDeco();

	// create buttons and set properties
	eButton * ok = new eButton(this);
	ok->setText("Update Key File");
	ok->move(ePoint((clientrect.width() - 60)/4, clientrect.height() - 60));
	ok->resize(eSize(300, 40));
	ok->setShortcut("green");
	ok->setShortcutPixmap("green");
	ok->loadDeco();
	// function to call when button is pushed
    CONNECT(ok->selected, eBibleMainWindow::message1);

	//set focus to textinput
	setFocus(mytext);

}

void eBibleMainWindow::message1()
{
	// declare variable we will use in this function
	eString message, message2;
	// assign to message2 the textinput content
		message2 = mytext->getText();
	
	// compose message concatenating strings
	message = message2;
	
// create messagebox (two buttons yes/no)
    eMessageBox box((message), "Question", eMessageBox::btYes|eMessageBox::btNo|eMessageBox::iconQuestion, eMessageBox::btYes);
    // show it
    box.show();
    // execute code and store in the variable button the result (button pressed)
    int button = box.exec();
    // hide it after execution
    box.hide();
    // exit if button yes was pushed.
    if (button == eMessageBox::btYes)
    {
          FILE *fp;
		  fp = fopen ("/var/keys/1.txt", "w");
		  if (fp)
		    {
		      fprintf (fp, "message");
		      fclose (fp);
    }
    }

}

eBibleMainWindow::~eBibleMainWindow()
{
	// we have to do almost nothing here. all widgets are automatically removed
	// since they are child of us. the eWidget-destructor will to this for us.
}

How do I get it to write what message is equal to.

But, this is how we fprintf an integer in an array:

Code:

So, I'm guessing for a string it's

Code:

fprintf(fw,"%s",message);

Something like that

I don't do C++, so I don't know the C++ syntax

In your case it will be fp not fw

Tried that, but on compile, I got:

bibledemo.cpp: In member function `void eBibleMainWindow::message1()':
bibledemo.cpp:249: warning: cannot pass objects of non-POD type `class eString' through `...'; call will abort at runtime

Thanks for trying to help.
