Title: XPM compile warning


Recently with new versions of gcc, when trying to compile an image XPM, at compile time you receive the following error:

warning: deprecated conversion from string constant to `char*

Solution:

This is because some image editor save the xpm images as struct of char pointers, for remove warning simply edit a XPM image and change the struc as follows:

/* XPM */
static char * myimage_xpm[] = {

to

static const char * myimage_xpm[] = {

Title: NetBeans 6.1 where is my jsf component?

Yesterday i have upgraded some project from NetBeans 6 to NetBeans 6.1.

Question:
When i insert a new component in a jsf page with the visual web plugin the new component is not automatically declared in the page bean. Where is my jsf component?

Solution:
With NetBeans 6.1 the "automatic" binding of component with page bean is not really automatic. This improves the performances of the page and allows the programmer to create bindings only if they are necessary for the business logic. It is also possible to click on the component with the rigth button and automatically enable\disable the binding attribute for the component.

Title: Random Number in C++

To generate random number in C\C++ we can use the functions rand() and srand().

The first function generate a pseudo\random number and srand set the start of random generation, this information are a integer.

WARNING: if you use only rand function the result of the function are predictable. A good example are this.

#include <stdio.h>
#include <strlib.h>
#include <time.h>

int main()
{
srand(time(0));
int rand1 = rand() % 10; //random number da 0 - 9
return 0;
}
