Read this question today about safe and unsafe code I then read about it in MSDN but I still don't understand it. Why would you want to use pointers in C#? Is this purely for speed?
I am trying to readthe 32-bit HKLM\SOFTWARE registry key from a 64-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node.
According to what I've found this is doable, but I can't seem to find a .NET example anywhere. I just need to read; not write. Anyone ran across this before?
I am using OLEDB method to read an excel file, however if the file is closed then there is no issues but if the file that has to be read is open then if i use oledb i get an error.

Hi
I want to read whole file contents in groovy on command line.
I am using this code
#!/usr/bin/env groovy
def xmlData =""
System.in.withReader {
xmlData=xmlData+ it.readLine()
}
println xmlData
and the following command
cat 1.xml | /root/a.groovy
But it only reads one line from the file. I want to read whole file.
Any suggestion??

i want to read serial port when there is some data present i mean on the event when data arrives only then i will read serial port instead of continuously reading the port i have this code for continuous reading the port how can i make it event based.
thanx in advance.
while(1)

bReadRC = ReadFile(m_hCom, &byte, 6, &iBytesRead, NULL);
printf("Data Recieved Through Serial port and no. of Bytes Recieved is %d",iBytesRead);

how do i set a sql server connection to readonly? i tried googling and all i found was File Mode=Read Only but it didnt work (File Mode keyword not supported). And the reference looked sql ce specific.
No luck with sqlite Read Only=True either.
I can read from a file 1 character at a time, but how do i make it go just one word at a time? So, read until there is a space and take that as a string.
This gets me the characters:
while (!fin.eof()){
while (fin f ){
F.push_back ( f );
}
I'm trying to write fully automated unit tests in JavaScript and I'm looking for a way to read some private variables in various JS functions. I thought I recalled a way to inject privileged members into a function/object (and found an overwhelming occurrence of "no such thing as private in JS") and yet I can't find any resources indicating how.
I'm trying to read through the properties of .prototype but if there's a way, someone out here would know where to direct me faster than I'd find on my own.
Thanks
I wonder if anyone could point me in the direction where I can read about the nuts and bolts of C#. What I'm interested in learning are method call costs, what it costs to create objects and such.
My aim of learning this is to get a better understanding of how increase the performance of an application and get a better understanding of how the C# language works.
The reference should preferable be a book, a book that I can read cover to cover.
I have a site collection and user A is having Design permissions in it.I created a subsite inheriting parent permissions and now I need to give just read permissions to user A in my subsite.
I have tried going to users and group of subsite ..created new group having read permissions and added that user into it...but its not working any idea ...how I can do this?
Hello dear commmunity, good day!
I run a little site (now for several months ) that has users accessing big files, for
download as well for streaming to the browser.
It's fairly active, so assuming the worst, how bad is getting php to readthe files that would be stored outside of the webroot and then getting it to echo it to a page dynamically for the browser to then read?
My question is: how bad is fread() etc in this context!?
zero

I don't really know much about sockets except how to read and write to them as if they were files. I know a little about using socket selectors. I don't get why you have to flush a socket, what's actually happening there? The bits just hang out somewhere in memory until they get pushed off? I read some things online about sockets, but it's all very abstract and high level.
What's actually happening here?
I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array.
I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams
I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.
I've worked with C++ in the last few years but never went through a book covering all the basics.
I've recently read Effective C++, but I feel it would be very important for me to read a more fundamental book as well.
Which one would be more recommended? C++ Primer or Thinking in C++?
A friend wrote a query with the following condition:
AND ( SELECT count(1) FROM users_alerts_status uas
WHERE uas.alert_id = context_alert.alert_id
AND uas.user_id = 18309
AND uas.status = 'read' ) = 0
Seeing this, I suggested we change it to:
AND NOT EXISTS ( SELECT 1 FROM users_alerts_status uas
WHERE uas.alert_id = context_alert.alert_id
AND uas.user_id = 18309
AND uas.status = 'read' )
But in testing, the first version of the query is consistently between 20 and 30ms faster (we tested after restarting the server). Conceptually, what am I missing?
I am reading one line at a time from a file, but at the end of each line it adds a '\n'.
example:
line is: 094 234 hii
but my input is: 094 234 hii\n
I want to read line by linem but I don't need to keep the newlines...
My goal is to read a list from every line: I need ['094','234','hii'], not ['094','234','hii\n']
Any advice?
The last time I worked with Zend_Db I recall I used to write SQL Queries manually. I've been searching for some ORM application, but, since I read something like Zend_Db is also capable of doing so, I started to try it, but I can't find neither a good tutorial explain it or a good documentation.
I read something lake Gateway pattern and ModelMapper class but I can't figure it out.
Can someone shine my path? :P
I have a jsp file in the root of .war file.
and then I have a folder named STUFF.
How do I get access to the file read.txt inside STUFF?
/Name_of_war/STUFF/read.txt is the correct path?
I have a dictionary of values read from 2 fields in a database: a string field and a numeric field. The string field is unique so that is the key of the dictionary.
I can sort on the keys, but how can I sort based on the values?
Note: I have read this post 72899 and probably could change my code to have a list of dictionaries but since I do not really need a list of dictionaries I wanted to know if there a simpler solution.
I looked at the MySql Connection Options and it doesnt seem to be there. Is there a way to create a read only connection/command for .NET? With SQLite i could specify read only=true to do this. What can i do with MySQL?
I've read some posts here and on the web about the differences of live() and delegate().
However I haven't found the answer I'm looking for (if this is a dupe please tell me).
I know the difference between live and delegate is that live can not be used in a chain.
As I also read somewhere delegate is in some case faster (better performance).
So I am wondering is there a situation where you would use live instead of delegate?
I have a microarray data of 38 row and 7130 columns. i am teying to readthe data but keeping having the above error.
I debugged and found when i readthe data, i have a 1x7129 instead of a 38x7130. I don't know why. my 7130th column contains letters while the rest of the data are numbers. Any idea why this is happening?
