  • Javascript "inlet" or "offset" function for drop-list options

    - by Camran
    I have seen on several sites that drop list values can have offsets... For example this drop-list: Fruits Apple Banana Orange Colors Red White Black The above are all options, but some have "inlets" or "offsets" or whatever you want to call it. How is this done with js? (regular js, not jquery at the moment) Thanks If you need more input let me know.

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

  • c# calculation help

    - by Jonas B
    Hi, I'm pretty useless when it comes to math and I have a problem I need help with. This has nothing to do with schoolwork, it's in fact about alcatel and the ticketextractor. I have two values that needs to be calculated in a c# application according to a formula specified in their documentation: "The global callid is equal to: callid1 multiplied by 2 power 32 plus callid2" As I said I'm not big with maths so that statement says nothing to me. If anyone know how to calculate it i'd appreciate it! Thanks

  • Delphi Math: Why is 0.7<0.70?

    - by Al C
    If I have variables a, b, an c of type double, let c:=a/b, and give a and b values of 7 and 10, then c's value of 0.7 registers as being LESS THAN 0.70. On the other hand, if the variables are all type extended, then c's value of 0.7 does not register as being less than 0.70. This seems strange. What information am I missing?

  • php Dollar amount Regular Expression

    - by Thildemar
    I am have completed javascript validation of a form using Regular Expressions and am now working on redundant verification server-side using PHP. I have copied this regular expression from my jscript code that finds dollar values, and reformed it to a PHP friendly format: /\$?((\d{1,3}(,\d{3})*)|(\d+))(\.\d{2})?$/ Specifically: if (preg_match("/\$?((\d{1,3}(,\d{3})*)|(\d+))(\.\d{2})?$/", $_POST["cost"])){} While the expression works great in javascript I get : Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 when I run it in PHP. Anyone have a clue why this error is coming up?

  • Stored procedures vs. parameter binding

    - by Gagan
    I am using SQL server and ODBC in visual c++ for writing to the database. Currently i am using parameter binding in SQL queries ( as i fill the database with only 5 - 6 queries and same is true for retrieving data). I dont know much about stored procedures and I am wondering how much if any performance increase stored procedures have over parameter binding as in parameter binding we prepare the query only once and just execute it later in the program for diferent set of values of variables.

  • Urgent help needed on How to update NSMutableDictionary. My code doesn't work.

    - by dawatson833
    I've populated an array using. arrSettings = [[NSMutableArray alloc] initWithContentsOfFile:[self settingsPath]]; The file is a plist with the root as an array and then a dictionary with three three keys defined as number. I've also tried setting the keys to string. I display the values in the plist file on a view using. diaper = [[arrSettings objectAtIndex:0] objectForKey:@"Diaper Expenses"]; oil = [[arrSettings objectAtIndex:0] objectForKey:@"Oil Used"]; tree = [[arrSettings objectAtIndex:0] objectForKey:@"Wood Used"]; This code works fine, the values in the dictionary are assigned to the variables and they are displayed. The user can make changes and then press a save button. I use this code to extract the dictionary part of the array so I can update it. The assignment to editDictionary works. I've double checked the key names including case and that is correct. editDictionary = [[NSMutableDictionary alloc] init]; editDictionary = [arrSettings objectAtIndex:0]; NSNumber *myNumber = [NSNumber numberWithFloat:diaperAmount]; [editDictionary setValue:myNumber forKey:@"Diaper Expenses"]; myNumber = [NSNumber numberWithFloat:oilAmount]; [editDictionary setValue:myNumber forKey:@"Oil Used"]; myNumber = [NSNumber numberWithFloat:treeAmount]; [editDictionary setValue:myNumber forKey:@"Wood Used"]; In this example I've used a nsnumber. But I've also tried the xxxAmount field as part of SetValue instead of creating a NSNumber. Neither implementation works. Several strange things happen. Sometimes the first two setvalue statements work, but the last setvalue fails with a EXC_BAD_ACCESS failure. Other times the first setValue fails with the same error. I have no idea why the first two sometimes work. I'm at a loss of what to do next. I've tried several implentations and none of them work. Also, in the debugger how can I display the editDictionary elements. I can see editDictionary, but I don't know how to display the individual elements.
