Hello

i am updating some numbers on a webpage and want the iphone app to retrieve those number.

suggestions are greatly welcomed.

I saw this post already. but unfortunately i am to much of a beginner to know how to implement this c code.

maybe someone can post an example project.

thanks a bunch.

i’m not shure if this is what you want or if its correct.

in your testApp.h

  
  
  
NSString *onlineTextYouWantToLoad;  
string convertedString;

in your testApp.mm <- dont forget to rename from .cpp to .mm (you are using Objective-C vars

  
  
//get the string from url to NSString  
onlineTextYouWantToLoad = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"[http://www.google.com"]];](http://www.google.com"]];)  
//make it a c++ string  
  
convertedString = [onlineTextYouWantToLoad UTF8String];

works great.

i also had to change main.cpp to main.mm

here my code with printing it to the screen:

  
ofSetColor(255,255,255);  
	char Str[1024];  
	  
	//get the string from url to NSString  
	onlineTextYouWantToLoad = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"[http://lozano-hemmer.com/stephan/test.html"]];](http://lozano-hemmer.com/stephan/test.html"]];)  
	//make it a c++ string  
	  
	convertedString = [onlineTextYouWantToLoad UTF8String];  
	  
	sprintf(Str, "%s", convertedString.c_str());  
	verdana.drawString(Str, 15,30);

yes, i forgot to tell you to change also main.cpp.

glad it works for you.
first time i’ve helped someone here, instead of asking for help.
