Programming :: Convert The String Data Type To Other Primitive Data Type?
Mar 4, 2011
I am trying to generic way to convert the string datatype to other primitive data type. To achieve, i used Template . But i getting error and couldn't resolve the issue and error reported is also clueless.
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I declared a variable as int data type which was a placeholder for a resulttatus (meaning, based on the result status that variable varies from 0/1/2/3. It can contain only these four values).data type is 4 byte integer in C#. But I can declare this variable as which represents a 1 byte integer. Since that variable contains only 1 or 2 or 3 or 4, declaring the variable asis wastage of memory space.Before declaring any variable we need to just think of the memory space needed for that variable, our requirement,
in c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)
I have a problem - I have files with rows of data and I need to check if the next row (of the same type) has the NEXT date in it so I need to extract a date in YYYYMMDD format from a row (easy enough) then add one day to it and compare it to the the next date I encounter on a subsequent row.
I'm working with Radiotap headers right now. I want to get the RSSI data. I came through a problem that I can't figure out right now.The value that I need to get is:
Code: s8 IEEE80211_RADIOTAP_DBM_ANTSIGNAL now, when I printf it:
I used xbindkeys and xvkbd to map my extra mouse buttons to page up and page down. With kde 4.4 it worked, but since I upgraded to kde 4.5 beta, I get the following error when xbindkeys starts:
Code:
*** Warning ***verify that there is not another program running which captures one of the keys captured by xbindkeys. It seems that there is a conflict, and xbindkeys can't grab all the keys defined in its configuration file. And for button press I get
Code:
Warning: Cannot convert string "-*-lucidatypewriter-bold-r-*-*-12-*-*-*-*-*-iso8859-1" to type FontStruct Warning: Cannot convert string "-*-helvetica-bold-r-*-*-12-*-*-*-*-*-iso8859-1" to type FontStruct
I am trying to convert a mdf file to iso with mdf2iso and this message pops up "Value too large for defined data type". The file is about 4.6 GB. Any other information
I've downloaded a big file from another server via "wget" to my /backup/ directory, and after the download was compeded I did run "ls" and the error was:ls: full_plesk_backup: Value too large for defined data type.
is there a way to recover data from a hd partition type fat32...cause ...cause right now it shows up as unallocated space..earlier i tried installing windows in a unused partition located just above this partition....i need to recover the data real soon...
i currently have both xubuntu 10.10 32-bit and windows 7 64-bit installed on my laptop which i use mostly for college work and basic programming (i'm still learning to program).i have a 150gb partition with win7 installed, a 20gb partition with xubuntu installed and a 15gb partition with my linux home folder on, the rest of the space is unused because i thought i may need it for something else in the future.the home folder partition is formatted to etc4, i now have a need to access this data from win7 for college work, i know that windows doesn't support mounting of etc file systems so i have hit a problem.
i thought about changing the type of partition from a ect4 to fat32 but will this delete my data? or ,are there any third party software packages for windows that will allow me to mount ect4?
i have Ubuntu10.10 (kernel-2.6.35-22-generic) installed. struct stat StatBuff;
[Code]...
I have mounted a windows share folder on /mnt. When i gave any directory within /mnt/ to stat function it fails with errorno 75. perror shows "Value too large for defined data type". Example 1 is fail but Example 2 works fine.
I make all as mentioned in this guide [URL] and the MediaTomb working with the script but when I try to open .mkv file PS3 says that "The data type is not supported" in same time it shows the files in the menu normally and marked it unsupported thumbnail after I try to play it.
I have a very large data file, with 3 numbers in each line, ex. 3 4 5 ; 6 7 8.I want to add two numbers (0 and 1) at the end of every line, and a string at the beginning of the line. Does anyone know a efficient way to do so?
Can anyone please suggest me how can we convert a wide char data in linux which is of 32 bit to a 16bit data. I have a file which has 16bit binary data? Could any one please give me ideas.
I have this JSON encoded data, which I want to efficiently parse (i.e. fast, with minimal system resources). I don't want to use a/the shell any more than necessary.
Here's a snippet of what the raw serial data looks like:
Code: [{"num":1,"name":"1","visible":false,"focused":false,"rect":{"x":0,"y":0,"width":1680,"height":1050},...blah blah.. So that's fine. I currently have at least two ways of parsing it:
This Perl method (which I don't much care for because I'm not much into Perl, and because the output is not much more useful than the raw form, and imho even more cryptic):
# Which means: at x=1680, draw a 20x20px grey block, then back up -10px and draw a "1" on the block.I figure that the two awk's I've used can be combined into one -- but I began having problems with removing the single quotes if I did it within the awk, which is why I stuck a `tr` in the middle.
I know this sucks. So, if someone has some ideas or thoughts on something else to do with this JSON data, that's less convoluted that where I'm currently going, I'll be happy to hear about it.
PS - I know this whole post is possibly hard to understand -- if you need more info (you mean you're interested in this mess?? )
Do I have the convert the int to a string using stringstream then convert the string to a char? or is there a more direct way?Also is there a way to tell the length of a int?
i used my windows box to connect to ftp(fed box) and i keep getting an error saying "The requested name is valid, but no data of the requested type was found." does anyone know why i cant connect?
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m error: can't perform indexing operations for <unknown type> type sh: gnuplot: not found Just to double check my work, I ran the following code: y=[1 2 3]; plot(y);
