Textbox.text returning blank
Due to security precautions ReadOnly fields do not persist their values upon postback. If you need to prevent user input into this field and still post the value back - do not set textbox'es ReadOnly property. Instead give it a ReadOnly appearance via CSS and then prevent user input thru something like txtShipmentDate.Attributes("onclick") = "this.blur();" (You may want to handle 'onselect' and 'onpaste' as well). This way user input is prevented, giving user complete ReadOnly field appearance and still value is posted back.

javascript not returning the value of a text input
okay i found the problem, and i would like to thank This link and This Link for helping me get to the answer. Okay so this was the actual problem: The iframe is created dynamically and the inputs were in the iframe (which i at first didnt feel the need to say in the original question) but after some further research and review i found that this was the cause of the problem I assume its because the input was in the iframe which is a seperate document (and i still stand under correction). So the actual code to get the value was document.getElementById('content').contentDocument.getElementsByName('edtGroupName').item(0).value which could also be solved using the methods mentioned in the links. for all beginners with js this is what the code does: //this gets the i frame of the c

returning text in xml using ajax with a function
Since your are using ajax the execution will be asynchronous, means you can't return any value from the ajax callback. The correct way to solve this is to use a callback method or use the ajax promise. Ex function preSubmit(callback){ var optionTexts = []; $("section").each(function(){ var h2 = $(this).find("h2").text(); //optionTexts.push("<b>"); optionTexts.push(h2); optionTexts.push(" "); $("ol li", this).each(function() { optionTexts.push($(this).text()) }) }); var splitText = optionTexts.join(" "); getFromWho().done(function(xml){ splitText += $(xml).find('recipient').text(); callback(splitText) }); } function getFromWho() { return $.ajax({ type: "GET", url: "forWho.xml",

Is there an efficient way of returning a sub-section of a text string
I believe you don't need to do anything as complicated - you can use the awesome package stringr's function str_extract str_extract(tmpstr,"[0-9]") This uses regex to extract only the numbers. Obviously, your real data might make this more complicated, but this should hopefully give you a good starting point. Edit A specific extraction between two full-stops, with the full-stops removed (with my poor regex skills I have to do it this long way) str_replace_all(str_extract(tmpstr,"[.][[:alnum:]]*[.]"),"\.","")

MySQL Full Text Search Returning 0 Results
With the current query you are looking for a full word match. So for instance to get the row you show inserted above, you would need to do: SELECT * FROM parentregionlist WHERE MATCH(regionnamelong) AGAINST ('Birmingham (and vicinity), England, United Kingdom' IN BOOLEAN MODE); However if you want to search for all results that start with 'Birm' you will need to add the '*' modifier: SELECT * FROM parentregionlist WHERE MATCH(regionnamelong) AGAINST ('Birm*' IN BOOLEAN MODE); Alternatively you could also use LIKE: SELECT * FROM parentregionlist WHERE regionnamelong LIKE 'Birm%'; The MySQL docs give good MATCH examples to work from: http://dev.mysql.com/doc/refman/5.5/en/fulltext-boolean.html

Reading from a text file in java is returning some garbage value
while ((string[i] = in.readLine()) != null) { System.out.println(string[2]); } over there you are missing the i++; However I would advise you to use this structure: Use a ArrayList instead of an array, since this allows you to have a self-resizing structure, also instead in the while use the method ready(); from the BufferedRead in order to check the end from the document, at the end the for it's just to display the elements in String ArrayList. ArrayList<String> string = new ArrayList<String>(); try { File file = new File("drive.txt"); BufferedReader entrada; entrada = new BufferedReader(new FileReader(file)); entrada.readLine(); while (entrada.ready()) { string.add(entrada.readLine())

Returning a text string from fortran subroutine to python using f2py
The problem here is with the len=* character declaration. you're telling the fortran compiler to accept any length string which was input. That's great except when you wrap it with f2py and have intent out, f2py needs to guess what length string to allocate and pass to your function and it has no way of doing that. (After all, what length string should it assume?). It looks to me like f2py assumes a 0 length string. When you assign a bigger string to a smaller string in fortran, the result gets truncated (although I would need to go back and read the standard to find out if that could result memory errors). In any event, it looks like that's what the gnu compiler is doing. If you change it to len=3, it works. Alternatively, doing something like this can make this work for f2py wi

Python - Chaining methods: returning `self` vs returning a new cloned object
Django does this so that the base query can be kept around and reused, without inheriting changes from a future "child" query, like your exclude() on your filter(). I'm guessing somebody tried storing queries for later, and realized that didn't work well without copying. I cloned the django repo and did a quick git log on django/db/models/query.py, searching for the phrase clone. The patch that introduces this change is here: https://github.com/django/django/commit/d4a3a4b

JavaScript, stringify, replacer - returning undefined vs. returning nothing
If you don't provide an explicit return, the return value is undefined. Your second function always returns undefined, in other words. Because the function always returns undefined, there'll never be anything included in the JSON stringified result, so the overall effect is that you get undefined. It's sort-of an anti-pattern to do this: if (something) { return whatever; } else { return somethingElse; } Your first function would be more idiomatic as: str = JSON.stringify(o,function(k,v) { return Object.isSealed(this) ? undefined : v; }); edit — note that JSON.stringify() calls your replacer function first with an empty key, and "v" equal to this a new wrapper object containing the object to be stringified (and note that that object is not sealed). That is, before chec

Returning 'nil' from a Lua function in C vs returning 0 values
Yes, this is perfectly valid. If you're trying to request/assign more return values than there are (no matter whether you try to get one or ten), you'll get nil for the undefined ones (i.e. those not returned). function test1() return 5 end local a, b = test1() -- a = 5, b = nil function test2() return 1, 2 end local c, d, e = test2() -- c = 1, d = 2, e = nil function test3() end local f, g = test3() -- f = nil, g = nil You probably can't find it in Lua's source because it's no special case or anything. It's just Lua's generic way to handle return values. Update: The difference you've noticed when trying to print return values is the fact that this is not just an assignment. Of course there is a slight difference between returning nil and returning nothing at all - and it

" " is the escaped character for a line break. So code like: label.Text = "This is a button"; Should put the word button on a new line. Edit: If you want to do it using the properties window in designer, click on the arrow on the far right of the text property field and it will open a small box. If you type multiple lines on that as you would normally (ie actually pressing enter, not using ) then the component will treat them as new lines and put the new lines in for you.

If you want to arbitrarily add text that is not known in advance and then later remove it, you'll need to either keep a list of items that have been added and regenerate the result each time, or do a search/replace operation to remove it.

Inserting text from text file into MySQL TEXT column
This is a possible duplicate of this question: http://serverfault.com/questions/316691/mysql-binlog-format-dilemma Anyway, the key is Statement is unsafe because it uses a system function that may return a different value on the slave. When the MySQL database is setup to use replication, system functions like load_file can cause issues. The file C: emp exttoinset.txt is likely different between the master server and the slave server (or may not even exist on one of them). When using replication, it is best to avoid system functions (like load_file and NOW()) because the values will be different when executed on different servers. If you want to load a file into a MySQL database that uses replication, consider using PHP's file_get_contents to read the file, and then use that to insert

Now reproduce this for 10 lines and you will get the same behaviour as you are having. If that's unwanted behaviour, you need to change your logic to take into account a line that is ending with a comma.
