• cannot edit any php files using specific functions

  - by user458474

  I cannot update any txt files using php. When I write a simple code like the following: <?php // create file pointer $fp = fopen("C:/Users/jj/bob.txt", 'w') or die('Could not open file, or fike does not exist and failed to create.'); $mytext = '<b>hi. This is my test</b>'; // write text to file fwrite($fp, $mytext) or die('Could not write to file.'); $content = file("C:/Users/jj/bob.txt"); // close file fclose($fp); ?> Both files do exist in the folder. I just cannot see any updates on bob.txt. Is this a permission error in windows? It works fine on my laptop at home. I also cannot change the php files on my website, using filezilla.

• Get multiple records with one query

  - by Lewy

  User table: name lastname Bob Presley Jamie Cox Lucy Bush Find users q = Query.new("Bob Presley, Cox, Lucy") q.find_users => {0=>{:name=>"Bob", :lastname=>"Presley"}, 1=>{:lastname=>"Cox"}, 2=>{:name=>"Lucy"}} Question: I've got hash with few names and lastnames. I need to build Activerecord query to fetch all users from that hash. I can do object = [] hash = q.find_users hash.each do |data| #check if data[:lastname] and data[:name] exist # object << User.where(:name => ..., :lastname => ...) end But I think it is higly inefficient. How should I do this ?

• Lua : Dynamicly calling a function with arguments.

  - by Tipx

  Using Lua, I'm trying to dynamicly call a function with parameters. What I want to have it done is I send a string to be parsed in a way that : 1st argument is a class instance "Handle" 2nd is the function to be called All that is left are arguments "modules" is a a table like { string= } split() is a simple parser that returns a table with indexed strings function Dynamic(msg) local args = split(msg, " ") module = args[1] table.remove(args, 1) if module then module = modules[module] command = args[1] table.remove(args, 1) if command then if not args then module[command]() else module[command](unpack(args)) -- Reference 1 end else -- Function doesnt exist end else -- Module doesnt exist end end When I try this with "ignore remove bob", by "Reference 1", it tries to call "remove" on the instance associated with "ignore" in modules, and gives the argument "bob", contained in a table (with a single value). However, on the other side of the call, the remove function does not receive the argument. I even tried to replace the "Reference 1" line with module[command]("bob") but I get the same result.

• Importing a spreadsheet into an asp.net program and listing the worksheets

  - by Bob Avallone

  I have to import the contents of a spreadsheet in my asp.net project. The code behind is c#. I figured out how to locate the spreadsheet on the user's computer and how to import the data from a given worksheet into a datable. The problem is I may not know the name of the worksheet ahead of time. I want to present the user with a list of available worksheets and have them pick one. That is the piece I don't know how to do. Thanks in advance. Bob Avallone

• vb.net - how do I parse a percentage value from a grid cell?

  - by Bob Palin

  I'm trying to parse a formatted percentage value back from a datagridviewcell that has been set with the "P" formatter: double percent = 0.96 cell.value = percent.tostring("p") gives me a displayed value of 96 % which is what I want. Now what I'm looking for is something like what is provided for the other formatting strings - NumberStyles.HexNumber, Currency etc so that I can do this double percent= double.parse( cell.value, NumberStyles.Percent ) which would give me a percent value of .96 I have scoured the .net documentation but can't find any sort of AllowPercent style like the others - is there one? Bob Palin p.s. I see there is another question here like this and tried to expand on it in that thread, but was deleted by a moderator and told to post a new question.

• Database design - alternatives for Entity Attribute Value (AEV)

  - by Bob

  Hi, see http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters for similar topic. My question: i want to design a database, that will be used for a production facility of different types of products where each product has its own (number of) parameters. because i want the serial numbers to be in one tabel for overview purposes i have a problem with these different paraeters . One solution could be AEV, but it has its downsides, certainly because we have +- 5 products with every product +- 20.000 serial numbers (records). it looks a bit overkill to me... I just don't know how one could design a database so that you have an attribute in a mastertable that says: 'hey, you could find details of this record in THAT detail-table". 'in a way that you qould easely query the results) currenty i am using Visual Basic & Acces 2007. but i'm going to Visual Basic & MySQL. thanks for your help. Bob

• Gridview changing text in a button column

  - by Bob Avallone

  I am working in asp.net using the gridview control. I have a button column that I create dynamically as such: ButtonField bfSelect = new ButtonField(); bfSelect.HeaderText = "View"; bfSelect.ButtonType = ButtonType.Link; bfSelect.CommandName = "View"; bfSelect.Text = "View"; grdAttachments.Columns.Add(bfSelect); The text on the button is the same for every row. I was wondering if there was any way to have the text be different for different rows depending on a condition. When I try to look at the text property of a particular row it is blank, if I try to set it, it does not change. Thanks in advance. Bob

• preg_replace to capitalize a letter after a quote

  - by Summer

  I have names like this: $str = 'JAMES "JIMMY" SMITH' I run strtolower, then ucwords, which returns this: $proper_str = 'James "jimmy" Smith' I'd like to capitalize the second letter of words in which the first letter is a double quote. Here's the regexp. It appears strtoupper is not working - the regexp simply returns the unchanged original expression. $proper_str = preg_replace('/"([a-z])/',strtoupper('$1'),$proper_str); Any clues? Thanks!!

• How to bulk insert from CSV when some fields have new line character?

  - by z-boss

  I have a CSV dump from another DB that looks like this (id, name, notes): 1001,John Smith,15 Main Street 1002,Jane Smith,"2010 Rockliffe Dr. Pleasantville, IL USA" 1003,Bill Karr,2820 West Ave. The last field may contain carriage returns and commas, in which case it is surrounded by double quotes. I use this code to import CSV into my table: BULK INSERT CSVTest FROM 'c:\csvfile.csv' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) SQL Server 2005 bulk insert cannot figure out that carriage returns inside quotes are not row terminators. How to overcome?

• Potential issues using member's "from" address and the "sender" header

  - by Paul Burney

  Hi all, A major component of our application sends email to members on behalf of other members. Currently we set the "From" address to our system address and use a "Reply-to" header with the member's address. The issue is that replies from some email clients (and auto-replies/bounces) don't respect the "Reply-to" header so get sent to our system address, effectively sending them to a black hole. We're considering setting the "From" address to our member's address, and the "Sender" address to our system address. It appears this way would pass SPF and Sender-ID checks. Are there any reasons not to switch to this method? Are there any other potential issues? Thanks in advance, -Paul Here are way more details than you probably need: When the application was first developed, we just changed the "from" address to be that of the sending member as that was the common practice at the time (this was many years ago). We later changed that to have the "from" address be the member's name and our address, i.e., From: "Mary Smith" <[email protected]> With a "reply-to" header set to the member's address: Reply-To: "Mary Smith" <[email protected]> This helped with messages being mis-categorized as spam. As SPF became more popular, we added an additional header that would work in conjunction with our SPF records: Sender: <[email protected]> Things work OK, but it turns out that, in practice, some email clients and most MTA's don't respect the "Reply-To" header. Because of this, many members send messages to [email protected] instead of the desired member. So, I started envisioning various schemes to add data about the sender to the email headers or encode it in the "from" email address so that we could process the response and redirect appropriately. For example, From: "Mary Smith" <[email protected]> where the string after "messages" is a hash representing Mary Smith's member in our system. Of course, that path could lead to a lot of pain as we need to develop MTA functionality for our system address. I was looking again at the SPF documentation and found this page interesting: http://www.openspf.org/Best_Practices/Webgenerated They show two examples, that of evite.com and that of egreetings.com. Basically, evite.com is doing it the way we're doing it. The egreetings.com example uses the member's from address with an added "Sender" header. So the question is, are there any potential issues with using the egreetings method of the member's from address with a sender header? That would eliminate the replies that bad clients send to the system address. I don't believe that it solves the bounce/vacation/whitelist issue since those often send to the MAIL FROM even if Return Path is specified.

• How does the hash part in hash maps work?

  So there is this nice picture in the hash maps article on Wikipedia: Everything clear so far, except for the hash function in the middle. How can a function generate the right index from any string? Are the indexes integers in reality too? If yes, how can the function output 1 for John Smith, 2 for Lisa Smith, etc.?
