    - by Jagdeep Singh
    I am having a problem in php switch case. When i set $number=0 it should run very first case but here this code returns 10-20K that is in second case. I checked comparison operators, tested them in if else case they return correct values but here first case do not run on $number=0 Why is this happening ? php consider 0 as false or something wrong in code ? Link to codepad paste http://codepad.org/2glDh39K also here is the code <?php $number = 0; switch ($number) { case ($number <= 10000): echo "0-10K"; break; case ($number > 10000 && $number <= 20000): echo "10-20K"; break; case ($number > 20000 && $number <= 30000): echo "20-30K"; break; case ($number > 30000 && $number <= 40000): echo "30-40K"; break; case ($number > 40000 && $number <= 50000): echo "40-50K"; break; case ($number > 50000 && $number <= 60000): echo "50-60K"; break; case ($number > 60000 && $number <= 70000): echo "60-70K"; break; case ($number > 70000 && $number <= 80000): echo "70-80K"; break; case ($number > 80000 && $number <= 90000): echo "80-90K"; break; case ($number > 90000): echo "90K+"; break; default: //default echo "N/A"; break; } ?>

  • How to debug issues with differing execution times in different contexts.

    - by Dave
    The following question seems to be haunting me more consistently than most other questions recently. What kinds of things would you suggest I suggest that they look for when trying to debug "performance issues" like this? ok, get this - running this in query analyzer takes < 1 second exec usp_MyAccount_Allowance_Activity '1/1/1900', null, 187128 debugging locally, this takes 10 seconds: DataSet allowanceBalance = SqlHelper.ExecuteDataset( WebApplication.SQLConn(), CommandType.StoredProcedure, "usp_MyAccount_Allowance_Activity", Params); same parameters

    How does C++ handle function pointers in relation to functions with defaulted parameters? If I have: void foo(int i, float f = 0.0f); void bar(int i, float f); void (*func_ptr1)(int); void (*func_ptr2)(int, float); void (*func_ptr3)(int, float = 10.0f); Which function pointers can I use in relation to which function?

  • Qwt setAxisScale() seems to lock up application when given numbers with greater precision than 2e-07

    - by Dane Larsen
    I'm using Qwt for some scientific graphing, and I'm working with some fairly small numbers, the smallest being around 1.0e-22. I'm trying to call setAxisScale(xaxis, xmin, xmax) //xmin = 0, xmax = 2.0e-10 But when I do, the application locks up. I haven't found anything in the documentation that refers to a minimum value. Xmin and xmax are both doubles, so that shouldn't be a problem. Is this a bug in Qwt, or am I doing something wrong? Thanks in advance

    - by Michaël
    Hi, I want to know if there is a short way to do the migrations down equivalent to rake db:migrate (for the migrations up).

But for : rake db:migrate:down VERSION=10, rake db:migrate:down VERSION=..., rake db:migrate:down VERSION=1, is there a shortcut? Tank you for your help!

  • Floats will not align, stay staggered, can't find a solution?

    - by Sarah Proper
    What I am trying to do is build a multi column layout. The main two sections are divided 2/3 to 1/3 and inside the 2/3 column is divided 2/3 1/3 as well. My problem is that my floats will not align nicely with each other, choosing instead to stagger like stairs. I have tried declaring the widths smaller, floating them individually, including in the float sections display:block,inline, or inline-block and nothing seems to be working. I am getting really frustrated and would appreciate any help!

  • I need a simple command line program to transform XML using XSLT

    - by fuzzy lollipop
    I am on OSX Snow Leopard (10.6.2) I can install anything I need to. I would preferably like a Python or Java solution. I have searched on Google and found lots of information on writing my own program to do this, but this is a just a quick and dirty experiment so I don't want to invest a lot of time on writing a bunch of code to do this, I am sure someone else has done this already.

  • How do I display children in succession, as3

Add, remove, appear, or disappear children, could all work. I want a simple way to display 1 child every second until I reach 10. METHODS TRYED addChild and removeChild visible !visible for loop

  • Any good SQL Anywhere database schema comparison tools?

    - by Lurker Indeed
    Are there any good database schema comparison tools out there that support Sybase SQL Anywhere version 10? I've seen a litany of them for SQL Server, a few for MySQL and Oracle, but nothing that supports SQL Anywhere correctly. I tried using DB Solo, but it turned all my non-unique indexes into unique ones, and I didn't see any options to change that.

  • Read variable-length records from a buffer - weird memory issues

    - by bsg
    Hi, I'm trying to implement an i/o intensive quicksort (C++ qsort) on a very large dataset. In the interests of speed, I'd like to read in a chunk of data at a time into a buffer and then use qsort to sort it inside the buffer. (I am currently working with text files but would like to move to binary soon.) However, my data is composed of variable-length records, and qsort needs to be told the length of the record in order to sort. Is there any way to standardize this? The only thing I could think of was rather convoluted: my program currently reads from the buffer until it hits a linefeed character ('10' in ascii), transferring each character over to another array. When it finds a linefeed (the delimiter in the input file), it fills the number of spaces remaining in the buffer for that record (record size is set to 30) with null characters. This way, I should end up with a buffer full of fixed-size records to give qsort. I know there are several problems with my approach, one being that it's just clumsy, another that the record size might conceivably be larger than 30, but is generally much less. Is there a better way of doing this? As well, my current code doesn't even work. When I debug it, it seems to be transferring characters from one buffer to the other, but when I try to print out the buffer, it contains only the first record. Here is my code: FILE *fp; unsigned char *buff; unsigned char *realbuff; FILE *inputFiles[NUM_INPUT_FILES]; buff = (unsigned char *) malloc(2048); realbuff = (unsigned char *) malloc(NUM_RECORDS * RECORD_SIZE); fp = fopen("postings0.txt", "r"); if(fp) { fread(buff, 1, 2048, fp); /*for(int i=0; i <30; i++) cout << buff[i] <<endl;*/ int y=0; int recordcounter = 0; //cout << buff; for(int i=0;i <100; i++) { if(buff[i] != char(10)) { realbuff[y] = buff[i]; y++; recordcounter++; } else { if(recordcounter < RECORD_SIZE) for(int j=recordcounter; j < RECORD_SIZE;j++) { realbuff[y] = char(0); y++; } recordcounter = 0; } } cout << realbuff <<endl; cout << buff; } else cout << "sorry"; Thank you very much, bsg

  • Help with Arrays in Objective C.

    Problem : Take an integer as input and print out number equivalents of each number from input. I hacked my thoughts to work in this case but I know it is not an efficient solution. For instance : 110 Should give the following o/p : one one zero Could someone throw light on effective usage of Arrays for this problem? #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int input, i=0, j,k, checkit; int temp[i]; NSLog(@"Enter an integer :"); scanf("%d", &input); checkit = input; while(input > 0) { temp[i] = input%10; input = input/10; i++; } if(checkit != 0) { for(j=i-1;j>=0;j--) { //NSLog(@" %d", temp[j]); k = temp[j]; //NSLog(@" %d", k); switch (k) { case 0: NSLog(@"zero"); break; case 1: NSLog(@"one"); break; case 2: NSLog(@"two"); break; case 3: NSLog(@"three"); break; case 4: NSLog(@"four"); break; case 5: NSLog(@"five"); break; case 6: NSLog(@"six"); break; case 7: NSLog(@"seven"); break; case 8: NSLog(@"eight"); break; case 9: NSLog(@"nine"); break; default: break; } } } else NSLog(@"zero"); [pool drain]; return 0; }
