I'm struggling with a C# program to read binary records from a database. The records were created with Borland Delphi. Error: You cannot use fixed size buffers contained in unfixed expressions. Try using the fixed statement.

im trying to get sed to read through a txt document that contains html and cant get it to copy over my code looks like Code: sed -n '/[width=468 height=60 border=0 /></a></center><hr>]/,/[<br clear=left><hr>]/p' 1.txt > 2.txt This is the code that seemed to have the best chance of working but still all it does is copy the whole txt document over instead of between these 2 expressions
View 3 Replies View Relatedi am trying to create an exclude regular expression for my build.xml. The problem is, that i am trying to find some info on which REs are acceptable/valid for ant... Is ant using standard regular expressions? POSIX ones? Since it is a java-based tool, the "Java REs" are probably valid. I am a little bit confused. If somebody can help me out with the different RE standards, i would be most obliged.

View 2 Replies View RelatedUsing the regex.h functions, how do you:
1) get the matched strings?
2) get the strings that matched sub-expressions?
Gidday, I'm puzzled as to why this works:
Code:
find /Data/ -type f -iname "*7pm*"
But this doesn't:
Code:
find /Data/ -type f -regex *7[Pp][Mm]*
I've tried MANY variations, but I'm getting no error messages, just no returns, and yet the first find, will find the sorts of files I'm looking for. I realise a win is a win, but I'm of the understanding that the -regex switch allows for some really complex use of regular expressions - but I can't even get a very simple one to work,
What I am doing is reading the text from a text document and storing all of the text inside of a ArrayList. I then set one of the values of the Arraylist as a string. I want to use regular expressions find out what the first two characters of the String are. if first two characters = "//" then function(); I only care about the first two characters though. If you need any more information, just ask.
View 4 Replies View RelatedI have this project for my operating systems class and I have put together the basic flow chart to aid me in writing the program. I know how to use pipes as a buffer to hold info. I know how to create a binary semaphore. But what I dont know is this:
How to "use a delay adjustment parameter K in the critical section to adjust the speed of the display process to show that without semaphore protection the displayed contents of the buffer are randomly interleaved."
First off, I am definitely not asking anyone to give me the solution. But I do need some guidance. So I figure there will be an if statement with two options:
1. If true, use semaphore protection to enter/exit critical section
2. If false, no semaphore protection -- this is where the contents of the buffer should be interleaved.
Now does that mean that as each child process enters the non-protected critical section, it should "sleep" for a randomized time? I mean, will this allow my output to be interleaved?
So lets say my command line looks like this:
what happens to the 100? Is it randomized using rand and srand and passed as a parameter to sleep() inside the critcal section?

I have 5.8GB of RAM.
I have 6.1GB of swap.
At some point in time my VMs exceeded the 5.8GB limit and overflowed into swap (all dev VMs). I have since shut down the VMs and restarted Firefox (memory hog). Right now I have 0.73GB in RAM and 0.29GB in swap. I want to move all of the data in swap into RAM where it will be faster. So I will end up with 1.02GB in RAM and 0GB in swap. Is there a quick command to move data contained within swap to RAM? I know of the swapon/swapoff command. I was wondering if there was another method which clears swap.

View 3 Replies View RelatedOn standard Linux setups you have two general paste buffers, the main copy(^C)/paste(^V) one and the select-text/middle-click one. For both of these buffers:
At what level in the environment are these buffers stored/managed; the kernel, the X server, KDE/Gnome, or some other service somewhere? Can they be programmatically accessed somehow using some standard library?

View 2 Replies View RelatedI am installing a new hard drive to replace my old one that contained the /var and /home directories. I don't want to copy the whole directories, especially from home because there is a lot I don't need in it.What I need to do is set the mount points for the two partitions I have made on the new drive to /var and /home, but it will not let me do this with the other drive still running. I can't unmount /var and /home while the computer is running, and I would guess that having two drives with /var and /home on them would not work.
So, how can I set the mount points on the new drive and copy the files I need from the old to the new one? It would seem that would require two /home partitions to be mounted at the same time, but I don't think that is possible. I am sure there is some way, probably many ways knowing Linux so please,

View 9 Replies View RelatedI switched from 11.1 to 11.2 last month. I'm now having a smoother experience with openSUSE, with some exceptions.
One is Emacs.
A rather annoying "feature" that has appeared is the following: When editing a LaTeX file, compiling it (C-c C-c, using AucTeX macros) makes the Emacs window become shorter by one line. The same happens if I switch to some other buffer. It does not happen if I switch back to the LaTeX buffer. So, after just a few editing/compiling/checking errors sequences I find the original window half of its initial size...
A similar problem occurs when editing IDLWAVE scripts (it's a proprietary scientific data analysis language widely used in my field, but still has its Emacs macros), but only if I open an interactive IDL-shell to run the script.
So, I imagine it's not a problem related to AucTeX, although it might be related to the macros opening separate buffers/windows (e.g.: error messages) associated with the current buffer. Also, the problem does not go away if I remove my own .emacs customization files. Checking the Emacs bug lists, it seems that there are some bugs related to window resizing, although I have not been able to find exactly the same problem I am having. But, before reporting this one, I'd like to hear from fellow Emacs/openSUSE users. Just in case I'm messing things up somehow.
Currently using: Emacs v 23.1.1
Some more info: Dell Precision M65 portable workstation, NVIDIA Quadro FX1500 using the binary NVIDIA driver). Using OpenSuse 11.2 + KDE 4.3.1
As per the documentation of sync [URL] , it schedules the writes but does not necessarily complete the write upon return.
Is there any other way to make sure we sync and it returns after it has written all the buffers to disk?
I'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.
I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.
I've been having a bad problem with X freezing up (but not the whole system), and I hate continually performing unclean shutdowns with the power button.Will an Alt+SysRq+o shut down the system in a way that doesn't cause the loss of disk buffers? Obviously, whatever hasn't been saved to the buffer will be lost, but my concern extends to the buffers themselves.ext4 and autofsck make this less of an issue, but I hate the thought of unnecessary silent corruption until the freezing stops.
