Parentheses weren't mean as a literal, they were there for easier readability. You can do this though


void someFunction(void)
{
int c = 123;
}


But you are correct, "void()" is...

No, a void() function can simply "return;", or doesn't even need a "return;" at all. Anything OTHER than a void() function, needs to return whatever you're casting the function as.

Fore example:...

Yes, it'll work fine, but there's no reason for a return value because you're not assigning the return value of extend() to anything in main(). Since you're not using the return value, just make...

In this EXAMPLE, am I free()ing this _strdup()'d return value correctly?



char *getText();

void someFunction(void)
{
char *msg = NULL;
msg = &*getText());

Thank you. (1,8) works perfect.

Only reason I did (0,9) is because if I did (0,8), I would get "XGCa:00"

Thank you, Salem, for pointing out (1,8). This has resolved my issue.

Yes, correct. And when I do Substring(0, 4), everything works great. My mistake totally. I suppose my "example" works fine, but here's my 'real' code that puzzles me.

When I run the following...

If I have the following test code:



String content = "This is a test";
String str = "This";
String lookFor = content.Substring(0, 5); // "This"
Boolean found = false;

// "found" should...

I think that I figured it out. Well, it *seems* to be working, although I'm not sure if I could/should have done it a better way.

Here's what I have now:

In "MainWindow.xaml.cs":

What I am trying to do (in brief terms):
I have a function in a .cs file (A) that needs to access a function in a different .cs file (B). Based on certain calculations, (B) will alter (A)...

Okay, so I add:



this.myTextBox.FontFamily = mFontCollection.Families[0];


And get this error:

I have successfully loaded a .ttf font. Now, how do I use it in a TextBox?

Yeah, typical. Heh, I suppose every forum has 'em. After taking a brief moment to read through some of your recent responses to posts, your arrogance and rudeness toward others is quite evident.

"...It is impossible for you to win this argument with me, so stop trying, because it's not even an argument..."

Wow, and where did all that pent up anger come from? I personally don't recall...

Not necessarily. It's more C than C++. It's a mix of both.

I need to pass a word to a function and have the first letter in that word "displayed" back to the user as a capital letter, the rest lower case.

I say "displayed" because I DO NOT want to change...

I completely understand, and agree. Because I'm in a pinch though, I (unfortunately) have to use the same name. I just needed confirmation that I wouldn't run into any memory or technical issues. ...

Just needed to know if it's safe. I have to do it for what I'm implementing. Thanks for the reply. (unless you could point out as to why I shouldn't do it, I guess I'm confused about: It's safe,...

This seems to work fine with no issues:


const int WORK_skill = 46;

#define WORK_skill(data) (data)->myStruct.element


The const int WORK_skill is, well, just an int and has absolutely...

Excellent. Thank you. I'm trying to eliminate as many _strdup's as possible so I don't have to "free" them later.

Here is my struct


struct pdat {
struct playerQuestInfo questData;
};

struct playerQuestInfo {
int questID[MAX_QUESTS_PER];
char *questObjectiveType[MAX_QUESTS_PER];

Got it... mostly. Thank you both for thorough reviews and helpful advice.

Well, I just tried this:



std::string sql(const char *dataIn)
{
std::string returnVal = "";
char *to = new char[(strlen(dataIn) * 2) + 1];
...

Interesting... I was just doing some testing with double quotes and single quotes regarding your point.

The program constantly crashes when I use single quotes. (Seems to break on malloc.c...
