error C2724: ‘ClassName::FunctionName’ : ‘static’ should not be used on member functions defined at file scope
Full error message: error C2724: ‘ClassName::FunctionName’ : ‘static’ should not be used on member functions defined at file scope
Error occurred in Visual Studio 2003 while declaring a static function.
Header file:
class MyClass {
public:
static void FunctionName();
};
Source file:
static void MyClass::FunctionName() {
return 0;
}
The error occurs because i used the ‘static’ modifier in the source file as well as the header file.
The fix is: Remove the ‘static’ modifier from the source file
So the code in the source file will become:
void MyClass::FunctionName() {
return 0;
}

My example:
// the Java class
public class Member {
// some private member attributes
private Date addedDate;
// proper getter and setter methods
}
<!– the Hibernate mapping–>
<hibernate-mapping> <class name="managemembers.Member" table="member"> <!-- some mappings here--> <property name="addedDate" type="timestamp" column="added_date"/> </class> </hibernate-mapping>
# The MySQL table
CREATE TABLE `member` ( # some fields here `added_date` DATETIME, ) ;
So I was mapping a java.util.Date field in the POJO to a MySQL DATETIME field.
The error occured while I was trying to retrieve the data from the member database table.
The problem was that I had DATETIME values in the database with all-zero components (0000-00-00 …), so the solution was to set all the added_date field values with all-zero components to NULL and to be careful to set a valid DATETIME value or NULL into the added_date field each time I inserted a new row.
Conclusion: You have 2 choices: either set the date field in the table to a NULL value either set it to a valid date.
error LNK2001: unresolved external symbol private: static …
Full error message: error LNK2001: unresolved external symbol “private: static <type> * <Class>::<memberVariable>” (?<memberVariable>@<C@@0PADA)
Error occured on Visual Studio 2003 when compiling a C++ project.
The error occurred because memberVariable was a static variable and it wasn’t initialized.
Example:
class A {
static char * filename;
static void F(void);
} ;
Fix:
char * A::filename = NULL;
The fix in my case is the following code added to the implementation of the <Class>:
<type> <Class>::<memberVariable> = <initValue>;
An XSLT stylesheet does not have an XML mimetype:
Full error message: Error loading stylesheet: An XSLT stylesheet does not have an XML mimetype:
Error occured on Firefox 2.0 when working with XML, XSLT.
xml file:
<?xml version="1.0" encoding="utf-8" ?> <?xml-stylesheet type="text/xsl" href="product-list.xslt"?> <f>PRODUCT DETAILS</f>
xslt file

<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" onLoad="alert('x');">
<value-of select="f"/>
</body>
</html>
</template>
</stylesheet>
The error occurs because the web server (in my case Apache) had this entry in the mime.types file:
text/xml xml xsl
The fix in my case is:
Change extenstion from xslt to xls on the stylesheet file or add xslt to the text/xml entry in mime.types file in Apache.
