space

just come across something I've never came across before. I have a value in my table "Device Vendor" and i am returning the data os an object. usually I would call $ob->var_name but obviously $ob->Device Vendor will not work. How do I return the value? Regards You use the following syntax $ob->{'Device Vendor'} The syntax is this: $ob->{'Device Vendor'} I'm having a hard time trying to find an explicit reference to this in the PHP manual. I'm afraid that it needs to be inferred and you can only do so if you already know the answer. At Classes and Objects-> Properties they say: Class member

In PHP, what's the most elegant way to get the complete list (array of strings) of all the Unicode whitespace characters , encoded in utf8? I need that to generate test data. This email contains a list of all Unicode whitespace characters encoded in UTF-8, UTF-16, and HTML. edit Originally answered Feb 9 '10 (!). Really guys, if the information is outdated, you can add your own answer, rather than complain. Just google for the URL mentioned in my answer, and earn some rep: The mail has been archived here (took me seconds), and the whitespace table is even mentioned in the introduction static

I have an input text field with a maxlength of 10. The field is for Australian phone numbers (10 digits). Phone numbers are generally split up into the following syntax 12 12345678 If someone copies the above and pastes that into my input field, it obviously leaves the last digit out and keeps the space. Is there a way to remove any spaces right before it is pasted into the input box? Or is there another work around? Thanks in advance. Paul This should work for you: HTML <input type="text" id="phone" maxlength="10" />​ JavaScript var phone = document.getElementById('phone'), cleanPhoneNumber;

In my android application I need to disABLE Spacebar only. But I didn't find a solution for this problem. I need to disable space bar and when user enter space should not work, special characters, letters, digits and all other should work. What I tried is, etPass.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub String str = s.toString(); if(str.length() > 0 && str.contains(" ")) { etPass.setError("Space is not allowed"); etPass.setText(""); } } @Override public void

I have a UIViewController set up to display an info-button on the right in its UINavigationItem like this: UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight]; [infoButton addTarget:self action:@selector(toggleAboutView) forControlEvents:UIControlEventTouchUpInside]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:infoButton] autorelease]; That works perfectly, but the only problem is that I'm left with little to no space to the right of the button, which looks pretty ugly: Is there any way for the button to move about 5 px out from the

It look like set tabstop=4 in VIM, but I don't know how to set it in bash for example: echo -e "1234567890\t321\n1\t2\n123\t1" current output: 1234567890 321 1 2 123 1 I want output like this: 1234567890 321 1 2 123 1 It can be shown in anywhere, just like cat somefile or php -r 'echo "\t123";' How can I set tab width in bash? That's not a property of your shell (or php or cat). It's your terminal that manages the output. Use the tabs command to change the behavior: $ tabs 4 $ echo -e "a\tb" a b $ tabs 12 $ echo -e "a\tb" a b ( tabs is specified in POSIX, and output above is "faked": it's

You're doing it the hard way. Use wmic . It's a lot faster and less complicated to scrape. for /f
