I would like to pass a string instead of the number. But don't know how to do that.
#define MODULE_A 5
#define MODULE_B 5
void function_2(unsigned moduleId, IdData)
{
if ( MODULE_A == moduleId) // want to compare the string instead of number 5 since both A and B are same.
{
// do something
}
if (MODULE_B == moduleId) //want to compare the string instead of number 5 since both A and B are same.
{
//do something
}
}
void function_1()
{
function_2(MODULE_B, IdData);
}
void function_3()
{
function_1(MODULE_A, IdData);
}
Welcome to do any workaround to archive the expected result. Basically, I have a function_2 that has the 1st element as unsigned integer, But when other function calling, I would like to pass the string inside each if condition but rather the value, since both module IDs are macro defined as the same number. Thank you.

I have 27 of these in my function:
auto i = m_lbLanguage.AddString(_T("Afrikaans (Afrikaans)"));
m_lbLanguage.SetItemData(i, static_cast<DWORD_PTR>(LanguageMSA::Afrikaans));
i = m_lbLanguage.AddString(_T("Cebuano (Cebuano)"));
m_lbLanguage.SetItemData(i, static_cast<DWORD_PTR>(LanguageMSA::Cebuano));
i = m_lbLanguage.AddString(_T("汉语（简化字）Chinese (Simplified)"));
m_lbLanguage.SetItemData(i, static_cast<DWORD_PTR>(LanguageMSA::ChineseSimplified));
Is this type of code a good candidate to use a lambda function? I know I can add a regular function, eg:
void Cxxx::AddLanguageToLB(CString strLanguage, LanguageMSA eLanguage)
{
auto i = m_lbLanguage.AddString(strLanguage);
m_lbLanguage.SetItemData(i, static_cast<DWORD_PTR>(eLanguage);
}
And the use:
AddLanguageToLB(_T("汉语（简化字）Chinese (Simplified)"), LanguageMSA::ChineseSimplified);
This type of code is a good candidate for a table-driven implementation. Something along these lines, perhaps:
struct {
LPCTSTR name;
LanguageMSA code;
} languages[] = {
{_T("Afrikaans (Afrikaans)"), LanguageMSA::Afrikaans},
{_T("Cebuano (Cebuano)"), LanguageMSA::Cebuano},
// ...
};
for (auto& lang : languages) {
auto i = m_lbLanguage.AddString(lang.name);
m_lbLanguage.SetItemData(i, static_cast<DWORD_PTR>(lang.code));
}

How do I make the first letter of a string uppercase in JavaScript?
(96 answers)
Closed 2 years ago.
I want to define a property on the string constructor, and I want then to access this property from any file in my project. for example:
file1.js
String.capitalize = function(){
this.//...etc
}
file2.js
"Hello nice to meet you".capitalize()
You can define a new String prototype function like in the example below
String.prototype.capitalize = function(){
return this.toUpperCase();
};
console.log("Hello nice to meet you".capitalize());

Consider the following condition in a if statement, is there a more idiomatic, clean, or readable way to write this?
if some_path_to_text_maybe
.extension()
.and_then(|ext| Some(ext == "txt"))
.unwrap_or(false) {
// do something
}
I guess this is one line less:
if some_path_to_text_maybe
.extension()
.map_or(false, |ext| ext == "txt") {
// do something
}
Alternatively, you could try the two-step:
if let Some(ext) = some_path_to_text_maybe.extension() {
if ext=="txt" {
// do something
}
}

For Instance, I have a class like this:
class firstOne{
....
def A (){
}
}
class secondOne{
// I need to call and use method A from class firstOne
// even I get error if I try to follow Java like calls
// firstOne method = new firstOne();
// method.A()
}
I already tried http://groovy.codehaus.org/Scripts+and+Classes and http://groovy.codehaus.org/Groovy+Beans but no way. Any kind of suggestion or examples would be really helpful.
I don't see any problem in this:
class FirstOne {
def a() {
println "a"
}
}
class SecondOne {
def b() {
new FirstOne().a()
println "b"
}
}
new FirstOne().a()
println("")
new SecondOne().b()
Output:
a
a
b
This is not specific to Groovy/Grails:
firstOne first = new firstOne()
first.A()
Also you should capitalize the first letter of classes, but not methods (as is best practice in Java).

Groovy, get enclosing function's name?
(5 answers)
Closed 8 years ago.
Is it possible to get the name of the current method in Groovy code?
def myMethod() {
// want to get the string myMethod here
}
Thanks
Tim_yates gives you a link to general solution.
This is shorter way to get method name. May be optimized, leawed as is for the sake of clarity.
class A {
def myMethod() {
for (m in new Throwable().stackTrace) {
if (m.className == this.class.name)
return m.methodName
}
}
}
println new A().myMethod()
