• Automate Monitor string in different log files

  - by EVIA

  I have few log files in different servers and I want to check output in the end of those log files for e.g . success: 4000 failed: 200 These logs files are getting generated daily and I have to keep track of these numbers. If there is any way I can automate this option instead of going and checking these files and wasting so much of my time. I want to create some kind of script like Go to \serverA\C$\log_07_02_2012.txt and check this line Go to \serverB\C$\log_07_02_2012.txt and check some other line. .... and it should give me output from all of these...

• convert char[] to String in btrace

  - by usovmv

  Hi folks! I'm profiling application with btrace (https://btrace.dev.java.net) and faced with limitation. I try to get a name of current java.lang.Thread. Normaly you can call getName() but it's forbidden in btrace-scripts (any calls exception BTraceUtils). Is there any idea how to get String from char[]. The original task is check if name of thread contains sub-string and only then log out tracing info (reducing output). thanks, Max.

• Conditional Branching Issues

  - by Zack

  Here is the code: def main_menu print_main_menu user_selected = gets.chomp if user_selected.downcase == "no" main_menu elsif user_selected == "1" || "2" || "3" || "4" || "5" || "6" || "7" user_selected = user_selected.to_i call_option(user_selected) else main_menu end end This code uses calls to allow a user to make a selection from a main menu. Depending on the input, be it a certain number, a certain word, or something else, the respective method is called (in the case of a valid input) or the main menu is printed again (in the case of an invalid input or "no"). My questions are twofold. 1) Is there an efficient way to get rid of the literal string error that appears as a result of this redundant or statement on the elsif line? (the code itself works fine, but this error appears and is frustrating). 2) When an alternate/unspecified input is made by the user, the else branch doesn't execute and main_method doesn't start over. I have no idea why this is happening. Is there something I'm missing here? Thanks

• Using traversal by pointer to check whether a string is repeated

  - by Bob John

  bool repeat_char(char *s, int n); //R: s is a C-string of at least n non-NUL characters and n > 0 //E: returns true if the first n characters are fully repeated throughout the string s, false // otherwise. I'm having trouble implementing this function using traversal by pointer. I was thinking that I could extract the first n characters from s, then use that in a comparison with s, but I'm not sure how I could do that. If I'm traversing through s one character at a time, how can I check that it matches a block of text, such as the first n characters of s? Thanks!

• Remove \r from a string in C++

  - by Werner

  Hi, in a C++ program, there is a point when it reads a string like: "NONAME_1_1\r" the \r is causing me trouble. I guess it prints or adds something like "^M". Is it right? Anyway it casues me problem, and I want to get rid of it. I can not modify the input. I wonder how could I at this point, using C++, and in the easiest way, to remove \r for this string. I know how to do it on bash but no clue on C++. Thanks.

• how to generate XML (in String representation) in java

  - by flyingfromchina

  I have defined a java class, but only need to output some of the fields of this class into an XML. The returned type must be a String. I first opted for the easiest way using a StringBuffer. However, when I tried to process the output String represenation, it failed. I think it is mostly likely because there are some characters that are not encoded in the UTF-8 in the input. Could someone tell me what is the best way to handle this? Thanks.

• String path validation

  - by CMAñora

  I have here a string(an input from the user) for a file path. I checked the string so that it will qualify the criteria: check for invalid characters for a file path will not accept absolute path (\Sample\text.txt) I have tried catching the invalid characters in catch clause. It work except for '\'. It will accept 'C:\\Sample\text.txt' which is an invalid file path. The following examples should be invalid paths: :\text.txt :text.txt \:text.txt \text.txt C:\\\text.txt I have been through similar questions posted here but none of them seemed to solve my issue. What would be the best way to do such check?

• C# Deserializing to a dictionary<string, Object>

  - by lovecraft

  I'm writing a C#/VB application to connect to a database and do stuff with the data. I was given this code to take a serialized byte array and deserialized it, which is then written to a Dictionary The line of code is: Dictionary<string, Object> DictionaryEmployee = (Dictionary<string, Object> Deserializer(byteArrayEmp)); The errors I'm getting are exceedingly unhelpful. "Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement" if I mouse over Object and "Using the generic type 'System.Collections.Generic.Dictionary' requires 2 type arguments if I mouse over Dictionary.

• Code Trivia #4

  - by João Angelo

  Got the inspiration for this one in a recent stackoverflow question. What should the following code output and why? class Program { class Author { public string FirstName { get; set; } public string LastName { get; set; } public override string ToString() { return LastName + ", " + FirstName; } } static void Main() { Author[] authors = new[] { new Author { FirstName = "John", LastName = "Doe" }, new Author { FirstName = "Jane", LastName="Doe" } }; var line1 = String.Format("Authors: {0} and {1}", authors); Console.WriteLine(line1); string[] serial = new string[] { "AG27H", "6GHW9" }; var line2 = String.Format("Serial: {0}-{1}", serial); Console.WriteLine(line2); int[] version = new int[] { 1, 0 }; var line3 = String.Format("Version: {0}.{1}", version); Console.WriteLine(line3); } } Update: The code will print the first two lines // Authors: Doe, John and Doe, Jane // Serial: AG27H-6GHW9 and then throw an exception on the third call to String.Format because array covariance is not supported in value types. Given this the third call of String.Format will not resolve to String.Format(string, params object[]), like the previous two, but to String.Format(string, object) which fails to provide the second argument for the specified format and will then cause the exception.

• How to subscribe to the free Oracle Linux errata yum repositories

  - by Lenz Grimmer

  Now that updates and errata for Oracle Linux are available for free (both as in beer and freedom), here's a quick HOWTO on how to subscribe your Oracle Linux system to the newly added yum repositories on our public yum server, assuming that you just installed Oracle Linux from scratch, e.g. by using the installation media (ISO images) available from the Oracle Software Delivery Cloud You need to download the appropriate yum repository configuration file from the public yum server and install it in the yum repository directory. For Oracle Linux 6, the process would look as follows: as the root user, run the following command: [root@oraclelinux62 ~]# wget http://public-yum.oracle.com/public-yum-ol6.repo \ -P /etc/yum.repos.d/ --2012-03-23 00:18:25-- http://public-yum.oracle.com/public-yum-ol6.repo Resolving public-yum.oracle.com... 141.146.44.34 Connecting to public-yum.oracle.com|141.146.44.34|:80... connected.

The "_latest" repositories that contain the errata packages are already enabled by default — you can simply pull in all available updates by running "yum update" next: [root@oraclelinux62 ~]# yum update Loaded plugins: refresh-packagekit, security ol6_latest | 1.1 kB 00:00 ol6_latest/primary | 15 MB 00:42 ol6_latest 14643/14643 Setting up Update Process Resolving Dependencies --> Running transaction check ---> Package at.x86_64 0:3.1.10-43.el6 will be updated ---> Package at.x86_64 0:3.1.10-43.el6_2.1 will be an update ---> Package autofs.x86_64 1:5.0.5-39.el6 will be updated ---> Package autofs.x86_64 1:5.0.5-39.el6_2.1 will be an update ---> Package bind-libs.x86_64 32:9.7.3-8.P3.el6 will be updated ---> Package bind-libs.x86_64 32:9.7.3-8.P3.el6_2.2 will be an update ---> Package bind-utils.x86_64 32:9.7.3-8.P3.el6 will be updated ---> Package bind-utils.x86_64 32:9.7.3-8.P3.el6_2.2 will be an update ---> Package cvs.x86_64 0:1.11.23-11.el6_0.1 will be updated ---> Package cvs.x86_64 0:1.11.23-11.el6_2.1 will be an update [...] ---> Package yum.noarch 0:3.2.29-22.0.1.el6 will be updated ---> Package yum.noarch 0:3.2.29-22.0.2.el6_2.2 will be an update ---> Package yum-plugin-security.noarch 0:1.1.30-10.el6 will be updated ---> Package yum-plugin-security.noarch 0:1.1.30-10.0.1.el6 will be an update ---> Package yum-utils.noarch 0:1.1.30-10.el6 will be updated ---> Package yum-utils.noarch 0:1.1.30-10.0.1.el6 will be an update --> Finished Dependency Resolution Dependencies Resolved ===================================================================================== Package Arch Version Repository Size ===================================================================================== Installing: kernel x86_64 2.6.32-220.7.1.el6 ol6_latest 24 M kernel-uek x86_64 2.6.32-300.11.1.el6uek ol6_latest 21 M kernel-uek-devel x86_64 2.6.32-300.11.1.el6uek ol6_latest 6.3 M Updating: at x86_64 3.1.10-43.el6_2.1 ol6_latest 60 k autofs x86_64 1:5.0.5-39.el6_2.1 ol6_latest 470 k bind-libs x86_64 32:9.7.3-8.P3.el6_2.2 ol6_latest 839 k bind-utils x86_64 32:9.7.3-8.P3.el6_2.2 ol6_latest 178 k cvs x86_64 1.11.23-11.el6_2.1 ol6_latest 711 k [...] xulrunner x86_64 10.0.3-1.0.1.el6_2 ol6_latest 12 M yelp x86_64 2.28.1-13.el6_2 ol6_latest 778 k yum noarch 3.2.29-22.0.2.el6_2.2 ol6_latest 987 k yum-plugin-security noarch 1.1.30-10.0.1.el6 ol6_latest 36 k yum-utils noarch 1.1.30-10.0.1.el6 ol6_latest 94 k Transaction Summary ===================================================================================== Install 3 Package(s) Upgrade 96 Package(s) Total download size: 173 M Is this ok [y/N]: y Downloading Packages: (1/99): at-3.1.10-43.el6_2.1.x86_64.rpm | 60 kB 00:00 (2/99): autofs-5.0.5-39.el6_2.1.x86_64.rpm | 470 kB 00:01 (3/99): bind-libs-9.7.3-8.P3.el6_2.2.x86_64.rpm | 839 kB 00:02 (4/99): bind-utils-9.7.3-8.P3.el6_2.2.x86_64.rpm | 178 kB 00:00 [...] (96/99): yelp-2.28.1-13.el6_2.x86_64.rpm | 778 kB 00:02 (97/99): yum-3.2.29-22.0.2.el6_2.2.noarch.rpm | 987 kB 00:03 (98/99): yum-plugin-security-1.1.30-10.0.1.el6.noarch.rpm | 36 kB 00:00 (99/99): yum-utils-1.1.30-10.0.1.el6.noarch.rpm | 94 kB 00:00 ------------------------------------------------------------------------------------- Total 306 kB/s | 173 MB 09:38 warning: rpmts_HdrFromFdno: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY Retrieving key from http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 Importing GPG key 0xEC551F03: Userid: "Oracle OSS group (Open Source Software group) " From : http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 Is this ok [y/N]: y Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Updating : yum-3.2.29-22.0.2.el6_2.2.noarch 1/195 Updating : xorg-x11-server-common-1.10.4-6.el6_2.3.x86_64 2/195 Updating : kernel-uek-headers-2.6.32-300.11.1.el6uek.x86_64 3/195 Updating : 12:dhcp-common-4.1.1-25.P1.el6_2.1.x86_64 4/195 Updating : tzdata-java-2011n-2.el6.noarch 5/195 Updating : tzdata-2011n-2.el6.noarch 6/195 Updating : glibc-common-2.12-1.47.el6_2.9.x86_64 7/195 Updating : glibc-2.12-1.47.el6_2.9.x86_64 8/195 [...] Cleanup : kernel-firmware-2.6.32-220.el6.noarch 191/195 Cleanup : kernel-uek-firmware-2.6.32-300.3.1.el6uek.noarch 192/195 Cleanup : glibc-common-2.12-1.47.el6.x86_64 193/195 Cleanup : glibc-2.12-1.47.el6.x86_64 194/195 Cleanup : tzdata-2011l-4.el6.noarch 195/195 Installed: kernel.x86_64 0:2.6.32-220.7.1.el6 kernel-uek.x86_64 0:2.6.32-300.11.1.el6uek kernel-uek-devel.x86_64 0:2.6.32-300.11.1.el6uek Updated: at.x86_64 0:3.1.10-43.el6_2.1 autofs.x86_64 1:5.0.5-39.el6_2.1 bind-libs.x86_64 32:9.7.3-8.P3.el6_2.2 bind-utils.x86_64 32:9.7.3-8.P3.el6_2.2 cvs.x86_64 0:1.11.23-11.el6_2.1 dhclient.x86_64 12:4.1.1-25.P1.el6_2.1 [...] xorg-x11-server-common.x86_64 0:1.10.4-6.el6_2.3 xulrunner.x86_64 0:10.0.3-1.0.1.el6_2 yelp.x86_64 0:2.28.1-13.el6_2 yum.noarch 0:3.2.29-22.0.2.el6_2.2 yum-plugin-security.noarch 0:1.1.30-10.0.1.el6 yum-utils.noarch 0:1.1.30-10.0.1.el6 Complete!

• IIS 7 can't connect to SQLServer 2008

  - by Nicolas Cadilhac

  Sorry if this is the most seen question on the web, but this is my turn. I am trying to publish my asp.net mvc app on IIS 7 under MS Sql Server 2008. I am on a Windows Server 2008 virtual machine. I get the following classical error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Under SQLServer, Allow remote connections is checked. My connection string is: Data Source=.\MSSQLSERVER;Initial Catalog=mydbname;User Id=sa;Password=mypassword I also tried with no username/password and "Integrated Security=true". There is only one instance of SQLServer installed. I tried to access my web page locally and remotely. There is no active firewall on the virtual machine. Thx for your help.

• Parsing a file in C

  - by sfactor

  I need parse through a file and do some processing into it. The file is a text file and the data is a variable length data of the form "PP1004181350D001002003..........". So there will be timestamps if there is PP so 1004181350 is 2010-04-08 13:50. The ones where there are D are the data points that are three separate data each three digits long, so D001002003 has three coordonates of 001, 002 and 003. Now I need to parse this data from a file for which I need to store each timestamp into a array and the corresponding datas into arrays that has as many rows as the number of data and three rows for each co-ordinate. The end array might be like TimeStamp[1] = "135000", low[1] = "001", medium[1] = "002", high[1] = "003" TimeStamp[2] = "135015", low[2] = "010", medium[2] = "012", high[2] = "013" TimeStamp[3] = "135030", low[3] = "051", medium[3] = "052", high[3] = "043" .... The question is how do I go about doing this in C? How do I go through this string looking for these patterns? Note: Here the seconds value in timestamp is added on our own as it is known at each data comes after 15 seconds.

• How bad is code using std::basic_string<t> as a contiguous buffer?

  - by BillyONeal

  I know technically the std::basic_string template is not required to have contiguous memory. However, I'm curious how many implementations exist for modern compilers that actually take advantage of this freedom. For example, if one wants code like the following it seems silly to allocate a vector just to turn around instantly and return it as a string: DWORD valueLength = 0; DWORD type; LONG errorCheck = RegQueryValueExW( hWin32, value.c_str(), NULL, &type, NULL, &valueLength); if (errorCheck != ERROR_SUCCESS) WindowsApiException::Throw(errorCheck); else if (valueLength == 0) return std::wstring(); std::wstring buffer; do { buffer.resize(valueLength/sizeof(wchar_t)); errorCheck = RegQueryValueExW( hWin32, value.c_str(), NULL, &type, &buffer[0], &valueLength); } while (errorCheck == ERROR_MORE_DATA); if (errorCheck != ERROR_SUCCESS) WindowsApiException::Throw(errorCheck); return buffer; I know code like this might slightly reduce portability because it implies that std::wstring is contiguous -- but I'm wondering just how unportable that makes this code. Put another way, how may compilers actually take advantage of the freedom having noncontiguous memory allows? Oh: And of course given what the code's doing this only matters for Windows compilers.

• Unicode strings in my C# App are shown with question marks

  - by mrbamboo

  Hi, I have a header file in C++/CLR project, which contains some strings in different languages. arabic, english, german, chinese, french, japanese etc... I have a second project written in C#. Here I access the strings stored in the header file of the C++/CLR project. The encoding of the header file is Unicode - Codepage 1200 or UTF-8. the visual studio editor is able to display the strings correctly. At runtime I access these strings and assign them into a local String variable. Here I recognized that many strings are not shown correctly. Doesn't matter if I assign them or not. Accessing the original place (while debugging) shows me all the foreign strings with question marks. Especially chinese, just question marks. Example : "So?e St?ange ?ext in Ch?n?se" (This is not the best example, I know) What is the problem? I read that C# is by default UTF-16, My header file containing the strings is UTF-16 or UTF-8. I must be able to handle strings in different languages. What am I doing wrong?

• going reverse in a for loop?

  - by sil3nt

  Hello there, Basically i got this for loop and i want the number inputed (eg. 123) to be printed out in reverse, so "321". so far it works fine and prints out the correct order when the for loop is for(i = 0; i<len ; i++) but i get an error when i try to print it in reverse?. Whats going wrong? #include <stdio.h> #include <string.h> void cnvrter(char *number); int main(){ char number[80]; printf("enter a number "); gets(number); cnvrter(number); return 0; } void cnvrter(char *number){ char tmp[80]; int i = 0,len = 0; int cnvrtd_digit = 0; len = strlen(number); printf("\nsize of input %d\n",len); for(i = len; i>len ; i--){ if ( ( number[i] >= '0' ) && ( number[i]<='9' ) ){ tmp[0] = number[i]; sscanf(tmp,"%d",&cnvrtd_digit); } printf("%d\n",cnvrtd_digit); } }

• Please help me with database connection types in Windows.

  - by Hamish Grubijan

  Sorry for a badly-phrased question. I have a requirement coming from a non-technical person that I need to make sense of. I am basically told: "Here use 'Driver={SQL Server};Server=SERVERNAME\INSTANCENAME;Database=DATABASENAME;Uid=UNAME;Pwd=PASSWORD;'; and here use Server=SERVERNAME\INSTANCENAME;Database=DATABASENAME;Uid=UNAME;Pwd=PASSWORD;';. I am getting no additional help here. While this seems to miraculously fix a bug, I want to understand what is it that I am changing, so I can leave a proper comment for the next developer, plus I can structure the code and name variables differently, depending on the meaning of the change. The work revolves around ASP.net, reporting, SQL Server 2008. Please give me some examples about when you would use one connection string over another. Feel free to edit the question if you can see a way to improve it. When can you lose a 'Driver={SQL Server};? Thank you. EDIT: SQL Server 2008 is the target database, but other can be used ... or maybe will be used in the future.

• categorize a set of phrases into a set of similar phrases

  - by Dingo

  I have a few apps that generate textual tracing information (logs) to log files. The tracing information is the typical printf() style - i.e. there are a lot of log entries that are similar (same format argument to printf), but differ where the format string had parameters. What would be an algorithm (url, books, articles, ...) that will allow me to analyze the log entries and categorize them into several bins/containers, where each bin has one associated format? Essentially, what I would like is to transform the raw log entries into (formatA, arg0 ... argN) instances, where formatA is shared among many log entries. The formatA does not have to be the exact format used to generate the entry (even more so if this makes the algo simpler). Most of the literature and web-info I found deals with exact matching, a max substring matching, or a k-difference (with k known/fixed ahead of time). Also, it focuses on matching a pair of (long) strings, or a single bin output (one match among all input). My case is somewhat different, since I have to discover what represents a (good-enough) match (generally a sequence of discontinuous strings), and then categorize each input entries to one of the discovered matches. Lastly, I'm not looking for a perfect algorithm, but something simple/easy to maintain. Thanks!

• php: replacing double <br /> with </p><p>

  - by andufo

  i use nicEdit to write RTF data in my CMS. The problem is that it generates strings like this: hello first line<br><br />this is a second line<br />this is a 3rd line since this is for a news site, i much prefer the final html to be like this: <p>hello first line</p><p>this is a second line<br />this is a 3rd line</p> so my current solution is this: i need to trim the $data for <br /> at the start/end of the string replace <br /><br /> with </p><p> (one single <br /> is allowed). finally, add <p> at the start and </p> at the end i only have the 3rd step so far. can someone give me a hand with steps 1 and 2? function replace_br($data) { # step 3 $data = '<p>'.$data.'</p>'; return $data; } thanks! ps: it would be even better to avoid specific situations. example: "hello<br /><br /><br /><br /><br />too much space" -- those 5 breaklines should also be converted to just one "</p><p>"

• system out output for double numbers in a java program

  - by Nikunj Chauhan

  I have a program where I am generating two double numbers by adding several input prices from a file based on a condition. String str; double one = 0.00; double two = 0.00; BufferedReader in = new BufferedReader(new FileReader(myFile)); while((str = in.readLine()) != null){ if(str.charAt(21) == '1'){ one += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51)); } else{ two += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51)); } } in.close(); System.out.println("One: " + one); System.out.println("Two: " + two); The output is like: One: 2773554.02 Two: 6.302505836000001E7 Question: None of the input have more then two decimals in them. The way one and two are getting calculated exactly same. Then why the output format is like this. What I am expecting is: One: 2773554.02 Two: 63025058.36 Why the printing is in two different formats ? I want to write the outputs again to a file and thus there must be only two digits after decimal.

• How do I connect to SQL Server with VB?

  - by Wayne Werner

  Hi, I'm trying to connect to a SQL server from VB. The SQL server is across the network uses my windows login for authentication. I can access the server using the following python code: import odbc conn = odbc.odbc('SignInspection') c = conn.cursor() c.execute("SELECT * FROM list_domain") c.fetchone() This code works fine, returning the first result of the SELECT. However, I've been trying to use the SqlClient.SqlConnection in VB, and it fails to connect. I've tried several different connection strings but this is the current code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim conn As New SqlClient.SqlConnection conn.ConnectionString = "data source=signinspection;initial catalog=signinspection;integrated security=SSPI" Try conn.Open() MessageBox.Show("Sweet Success") 'Insert some code here, woo Catch ex As Exception MessageBox.Show("Failed to connect to data source.") MessageBox.Show(ex.ToString()) Finally conn.Close() End Try End Sub It fails miserably, and it gives me an error that says "A network-related or instance-specific error occurred... (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I'm fairly certain it's my connection string, but nothing I've found has given me any solid examples (server=mySQLServer is not a solid example) of what I need to use. Thanks! -Wayne

• PHP array value becomes blank. What is going on?

  - by Michael Bruce

  I have written a web page that works fine expect for some weird behavior. The code below gets all expected values and populates them correctly except for $v-data["quick_phone_id"] and $v-data["quick_email_id"] which are integers. Those values come out blank in the string I am creating. The value for $v-data["id"] is another integer and works as expected. My only clue is that when I uncomment the commented out line, the code works properly. So I'm guessing this has to do with referencing getting broken for the array. Any ideas? I'd like to fix my code and my PHP knowledge. $contacts = ContactInfo::loadMyContacts($userId); $sb = new StringBuilder(); $idx = 0; //$vals = "vals: ".$contacts[0]->data["quick_phone_id"]; $sb->append(' dataRows = ['); foreach($contacts as $k => $v) { $sb->append('{ id:"'.strval($v->data["id"]).'",'); $sb->append('url:"edit_contact.php?id='.$v->data["id"].'",'); $sb->append('gname:"'.$v->data["given_name"].'",'); $sb->append('fname:"'.$v->data["family_name"].'",'); $sb->append('phone1id2:"'.strval($v->data["quick_phone_id"]).'",'); $sb->append('phone1type:"'.$v->data["quick_phone_type"].'",'); $sb->append('phone1:"'.$v->data["quick_phone"].'",'); $sb->append("email1id2:'".strval($v->data["quick_email_id"])."',"); $sb->append('email1type:"'.$v->data["quick_email_type"].'",'); $sb->append("email1:'".$v->data["quick_email"]."',"); $sb->append("dirty:false },\n"); } $sb->append('];');
