  • VB6 ADO Command to SQL Server

    - by Emtucifor
    I'm getting an inexplicable error with an ADO command in VB6 run against a SQL Server 2005 database. Here's some code to demonstrate the problem: Sub ADOCommand() Dim Conn As ADODB.Connection Dim Rs As ADODB.Recordset Dim Cmd As ADODB.Command Dim ErrorAlertID As Long Dim ErrorTime As Date Set Conn = New ADODB.Connection Conn.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Initial Catalog=database;Data Source=server" Conn.CursorLocation = adUseClient Conn.Open Set Rs = New ADODB.Recordset Rs.CursorType = adOpenStatic Rs.LockType = adLockReadOnly Set Cmd = New ADODB.Command With Cmd .Prepared = False .CommandText = "ErrorAlertCollect" .CommandType = adCmdStoredProc .NamedParameters = True .Parameters.Append .CreateParameter("@ErrorAlertID", adInteger, adParamOutput) .Parameters.Append .CreateParameter("@CreateTime", adDate, adParamOutput) Set .ActiveConnection = Conn Rs.Open Cmd ErrorAlertID = .Parameters("@ErrorAlertID").Value ErrorTime = .Parameters("@CreateTime").Value End With Debug.Print Rs.State ' Shows 0 - Closed Debug.Print Rs.RecordCount ' Of course this fails since the recordset is closed End Sub So this code was working not too long ago but now it's failing on the last line with the error: Run-time error '3704': Operation is not allowed when the object is closed Why is it closed? I just opened it and the SP returns rows. I ran a trace and this is what the ADO library is actually submitting to the server: declare @p1 int set @p1=1 declare @p2 datetime set @p2=''2010-04-22 15:31:07:770'' exec ErrorAlertCollect @ErrorAlertID=@p1 output,@CreateTime=@p2 output select @p1, @p2 Running this as a separate batch from my query editor yields: Msg 102, Level 15, State 1, Line 4 Incorrect syntax near '2010'. Of course there's an error. Look at the double single quotes in there. What the heck could be causing that? I tried using adDBDate and adDBTime as data types for the date parameter, and they give the same results. When I make the parameters adParamInputOutput, then I get this: declare @p1 int set @p1=default declare @p2 datetime set @p2=default exec ErrorAlertCollect @ErrorAlertID=@p1 output,@CreateTime=@p2 output select @p1, @p2 Running that as a separate batch yields: Msg 156, Level 15, State 1, Line 2 Incorrect syntax near the keyword 'default'. Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword 'default'. What the heck? SQL Server doesn't support this kind of syntax. You can only use the DEFAULT keyword in the actual SP execution statement. I should note that removing the extra single quotes from the above statement makes the SP run fine. ... Oh my. I just figured it out. I guess it's worth posting anyway.

  • Developing "Command Line" in .NET?

    - by Sergey Malyan
    Imagine a "search box" on the right top side of the UI Windows Application. When user types a desired action, a matching functionality is executed. Screen gets opened, or action gets performed. For example: user types "create" and intellisence offered next word options "client"/"product", user picks "client", and "Create New Client" screen opens up. So what I am looking for if there is a framework support for this. I assume that framework shall bind together text commands names, commands and show in intellisense. Same framework possibly could have been used in alternative "Command Line interface". I recall Microsoft had some recent framework that helps to setup "command Line Interface" environmental. It is hard to search on web for this keywords, so relying on intelligent help from you guys. Thanks in advance.

  • Shell - How to find directory of some command?

    - by Gabriel L. Oliveira
    I know that when you are on shell, the only commands that can be used are the ones that can be found on some directory set on PATH. Even I don't know how to see what dirs are on my PATH variable (and this is another good question that could be answered), what I'd like to know is: I come to shell and write: $ lshw I want to know a command on shell that can tell me WHERE this command is located. In other words, where this "executable file" is located? Something like: $ location lshw /usr/bin Anyone?

  • starting .net application from command prompt is having issue when path is in SHORTNAME

    - by ioWint
    when we start our .net application using a double click on the explorer or from command prompt where your folder path is proper full name then there is no issue at all. But when you start it from command prompt with the path being a Shortname involving a ~ the application behaves weird. IF is entering condition though the condition evaluates to FALSE in quick watch. Accessing a value of a variable in quick watch and immediate window shows value. but when you use it to assign to another variable in code, it returns NULL / no value. another observation: when you attach Visual studio to debug the app, and when you go about "Set as next statement" visual studio is giving options to select which dll to work up on. i have never seen this prompt before!

  • Concatenate text files with Windows command line, dropping leading lines

    - by James
    I need to concatenate some relatively large text files, and would prefer to do this via the command line. Unfortunately I only have Windows, and cannot install new software. type file1.txt file2.txt > out.txt allows me to almost get what I want, but I don't want the 1st line of file2.txt to be included in out.txt. I have noticed that more has the +n option to specify a starting line, but I haven't managed to combine these to get the result I want. I'm aware that this may not be possible in Windows, and I can always edit out.txt by hand to get rid of the line, but is there a simple way of doing it from the command line?

  • Haskell: reading multiple command line arguments

    - by Survot
    Hi all, Okay, so I am making a program in Haskell that needs to change certain words based on two command line arguments. I have made the replace function and everything works great, but I am stumped getting it to work with command line arguments. Here is the main code: (replace function not included) main = do text <- getContents (command1:command2:_) <- getArgs putStrLn (replace (read command1) (read command2) text) So for intstance in the terminal I want to be able to type something like: "--- cat textfile.txt | ./replace oldword newword" I know this code is close since I have seen others do it this way. O_o Thanks for any help

  • Batch file crashes when double clicked, but passes from command prompt

    - by devinb
    I have a batch file that was crashing when executing from windows explorer. I opened a command prompt and navigated to the file, but when I executed it there it did not crash. I identified the line that was crashing. SET list =(Company.Framework^ Company.SharePoint.Lists.News^ Company.SharePoint.WebControls^ Company.SharePoint.WebParts.NewsList^ Company.SharePoint.WebParts.RedirectWebPart^ Company.SharePoint.WebParts.IFrameWebPart^ Company.SharePoint.WebParts.ItemRotatorWebPart^ Company.SharePoint.WebParts.InteractiveMapWebPart^ Company.SharePoint.WebParts.SiteMapWebPart^ Company.SharePoint.Branding.PrettyUnicorns) ::Do stuff ::Failure occurs here FOR %%F in %list% DO ( ::Doesn't matter what is in here ECHO Woo! ) Is any reason why a batch file would behave differently from Windows Explorer vs Command Prompt?

  • tools for creating user-friendly command-line prompt?

    - by davka
    I notice that some programs (e.g. sqlite, mysql client) provide a command-line prompt that is very similar in capabilities to the bash's, including: line editing with left and right arrows, delete, insert, ^K, etc. history browsing with up and down arrows ^R for reverse i-search in command history which make me think that they are using the same toolset for this. I'd like to create a prompt with similar capabilities in my program, which tools can I use? I prefer it to have the same functionality as in bash, so that the users would be familiar with it.

  • command design pattern usage

    - by sagie
    Hi. I've read 3 descriptions of the command design pattern: wikipedia, dofactory and source making. In all of them, the UML shows a relation between the client to the receiver & the concrete command, but no relation to the invoker. But in all 3 examples the client is the one that initiates the invoker and call its Execute method. I think that should be a relation to the invoker as well. Am I missing somthing in here? Maybe even a basic UML knowladge?

    There is a file that hosted remotely on a server that is not supporting Shell Access. I bought a new server that supports Shell Access so now I want to copy a file that is on the non-supporting server to new server via a Shell Command using Putty. File url is like this http://www.domain.com/file.gzip and it is username/password protected. To be more specific, I want to copy a backup of a home directory from cPanel to my new server via Shell command. I have done this few months ago but I don't remember it now and also I failed to Google it.

  • How to animate the command line?

    - by The.Anti.9
    I have always wondered how people update a previous line in a command line. a great example of this is when using the wget command in linux. It creates an ASCII loading bar of sorts that looks like this: [======                    ] 37% and of course the loading bar moves and the percent changes, But it doesn't make a new line. I cannot figure out how to do this. Can someone point me in the right direction?

  • How do you reset a USB device from the command line?

    - by Casey
    Is it possible to reset the connection of a USB device, without physically disconnecting/connecting from the PC? Specifically, my device is a digital camera. I'm using gphoto2, but lately I get "device read errors", so I'd like to try to do a software-reset of the connection. From what I can tell, there are no kernel modules being loaded for the camera. The only one that looks related is usbhid.

    Hi guys, i have a program that needs command line arguments in the form : ./my_program -m256M -tm -t some_other_file The "some_other_file" argument is not bound to -t (-t it's just another functionality) so i can't take it as the optarg of any of the flags, neither can i assume it is the last argument in the list. How can i do this? Thanks

  • Parse multiple named command line parameters

    - by scholzr
    I need to add the ability to a program to accept multiple named parameters when opening the program via the command line. i.e. program.exe /param1=value /param2=value and then be able to utilize these parameters as variables in the program. I have found a couple of ways to accomplish pieces of this, but can't seem to figure out how to put it all together. I have been able to pass one named parameter and recover it using the code below, and while I could duplicate it for every possible named parameter, I know that can't be the preffered way to do this. Dim inputArgument As String = "/input=" Dim inputName As String = "" For Each s As String In My.Application.CommandLineArgs If s.ToLower.StartsWith(inputArgument) Then inputName = s.Remove(0, inputArgument.Length) End If Next Alternatively, I can get multiple unnamed parameters from the command line using My.Application.CommandLineArgs But this requires that the parameters all be passed in the same order/format each time. I need to be able to pass a random subset of parameters each time. Ultimately, what I would like to be able to do, is separate each argument and value, and load it into a multidimentional array for later use. I know that I could find a way to do this by separating the string at the "=" and stripping the "/", but as I am somewhat new to this, I wanted to see if there was a "preffered" way for dealing with multiple named parameters?

  • parsing the output of the 'w' command?

    - by Blackbinary
    I'm writing a program which requires knowledge of the current load on the system, and the activity of any users (it's a load balancer). This is a university assignment, and I am required to use the w command. I'm having a hard time parsing this command because it is very verbose. Any suggestions on what I can do would be appreciated. This is a small part of the program, and I am free to use whatever method i like. The most condensed version of w which still has the information I require is `w -u -s -f' which produces this: 10:13:43 up 9:57, 2 users, load average: 0.00, 0.00, 0.00 USER TTY IDLE WHAT fsm tty7 22:44m x-session-manager fsm pts/0 0.00s w -u -s -f So out of that, I am interested in the first number after load average and the smallest idle time (so i will need to parse them all). My background process will call w, so the fact that w is the lowest idle time will not matter (all i will see is the tty time). Do you have any ideas? Thanks (I am allowed to use alternative unix commands, like grep, if that helps).

  • Run a command as cron would but from the command line.

    - by BCS
    I have a script that I'm trying to run from cron. When I run it from bash, it work just fine. However when I let cron do it's thing, I get a: myscript.sh: line 122: syntax error: unexpected end of file What I want is a way to run a command as if it was a cron job, but do it in my shell. As a side note: does anyone know what would be differnt under cron? (the script already has a #!/bin/sh line) To answer my own question: I added this to my crontab: * * * * * bcs for ((i=1; i <= 55; i++)) ; do find ~/.crontemp/ -name '*.run' -exec "{}" ";" ; sleep 1; done` and created this script: #!/bin/sh tmp=$(mktemp ~/.crontemp/cron.XXXXX) mknod $tmp.pipe p mv $tmp $tmp.pre echo $* '>' $tmp.pipe '1>&2' >> $tmp.pre echo rm $tmp.run >> $tmp.pre chmod 700 $tmp.pre mv $tmp.pre $tmp.run cat $tmp.pipe rm $tmp.pipe With that, I can run an arbitrary command with a delay of not more than one second. (And yes, I know there are all kinds of security issue involved in that)

  • Nagios "CRITICAL - Socket timeout after 10 seconds" problems with service and host Checks.

    - by Kristiaan
    Hi Everyone, got a little bit of a problem with a Nagios system we are using in our office, which has only recently started appearing. what i would like to know really is the best solution to resolve this problem as ive done a bit of reading on it and there seems to be lots of different ways to solve it.. basically at random points throughout the day and on random hosts / services we will get a Critical warning flagged up that something is not behaving as it should, when we investigate 9 times out of 10 we end up with this as an error message. "SERVICE ALERT: SERVERNAME ;NSClient++ Version;CRITICAL;SOFT;1;CRITICAL - Socket timeout after 10 seconds" indicating the service or host has timed out, where do i go about setting the timeouts so this stops ? ive read that some of the plugin timesouts are as low as 10 seconds... thanks Kris

  • juju spends bootstrap-timeout with a final message it cannot find /var/lib/juju/nonce.txt

    - by user285199
    I build two VMware's machines. First one with MAAS, second one with a fresh installation from MAAS. Region controller was installed with Ubuntu 12.04 distribution, and upgraded (. Node computing was installed from MAAS with Quantal 12.10. Juju was installed and upgraded to 1.18 (from ppa:juju/stable repository). MAAS was upgraded from cloud-archive:tools repository. In debug mode, I got how Juju connects to node. Then I run the same instruction: ssh -o "StrictHostKeyChecking no" -o "PasswordAuthentication no" -i /home/lliurex/.juju/ssh/juju_id_rsa -i /home/lliurex/.ssh/id_rsa [email protected] /bin/bash It worked (with and without /bin/bash). When Juju spends all bootstrap-timeout tells it has not found /var/lib/juju/nonce.txt file. It's true, it doesn't exist. It doesn't mind if you put a timeout of 1800, 3600 or 72000, it always finishes the same.

  • First Foray&ndash;About timeout

    - by SQLMonger
    It has been quite a while since I signed up for this blog site and high time that something was posted.  I have a list of topics that I will be working through and posting.  Some I am sure will have been posted by others, but I will be sticking to the technical problems and challenges that I’ve recently faced, and the solutions that worked for me.  My motto when learning something new has always been “My kingdom for an example!”, and I plan on delivering useful examples here so others can learn from my efforts, failures and successes.   A bit of background about me… My name is Clayton Groom. I am a founding partner of a consulting firm in St. Louis Missouri, Covenant Technology Partners, LLC and focus on SQL Server Data Warehouse design, Analysis Services and Enterprise Reporting solutions.  I have been working with SQL Server since the early nineties, when it still only ran on OS/2. I love solving puzzles and technical challenges.   Enough about me… On to a real problem… SSIS Connection Time outs versus Command Time outs Last week, I was working on automating the processing for a large Analysis Services cube.  I had reworked an SSIS package and script task originally posted by Vidas Matelis that automates the process of adding new and dropping old partitions to/from an Analysis Services cube.  I had the package working great, tested, and ready for deployment.  It basically performs a query against the source system to determine if there is new data in the warehouse that will require a new partition to be added to the cube, and it checks the cube to see if there are any partitions that are present that are no longer needed in a rolling 60 month window. My client uses Tivoli for running all their production jobs, and not SQL Agent, so I had to build a command line file for Tivoli to use to run the package. Everything was going great. I had tested the command file from my development workstation using an XML configuration file to pass in server-specific parameters into the package when executed using the DTExec utility. With all the pieces ready, I updated the dtsconfig file to point to the UAT environment and started working with the Tivoli developer to test the job.  On the first run, the job failed, and from what I could see in the SSIS log, it had failed because of a timeout. Other errors in the log made me think that perhaps the connection string had not been passed into the package correctly. We bumped the Connection Manager  timeout values from 20 seconds to 120 seconds and tried again. The job still failed. After changing the command line to use the /SET option instead of the /CONFIGFILE option, we tested again, and again failure. After a number more failed attempts, and getting the Teradata DBA involved to monitor and see if we were connecting and failing or just failing to connect, we determined that the job was indeed connecting to the server and then disconnecting itself after 30 seconds.  This seemed odd, as we had the timeout values for the connection manager set to 180 seconds by then.  At this point one of the DBA’s found a post on the Teradata forum that had the clues to the puzzle: There is a separate “CommandTimeout” custom property on the Data source object that may needed to be adjusted for longer running queries.  I opened up the SSIS package, opened the data flow task that generated the partition list table and right-clicked on the data source. from the context menu, I selected “Show Advanced Editor” and found the property. Sure enough, it was set to 30 seconds. The CommandTimeout property can also be edited in the SSIS Properties sheet. In order to determine how long the timeout needed to be, I ran the query from the task in the development environment and received a response in a matter of seconds.  I then tried the same query against the production database and waited several minutes for a response. This did not seem to be a reasonable response time for the query involved, and indeed it wasn’t. The Teradata DBA’s adjusted the query governor settings for the service account I was testing with, and we were able to get the response back down under a minute.  Still, I set the CommandTimeout property to a much higher value in case the job was ever started during a time of high-demand on the production server. With this change in place, the job finally completed successfully.  The lesson learned for me was two-fold: Always compare query execution times between development and production environments, and don’t assume that production will always be faster.  With higher user demands, query governors, and a whole lot more data, the execution time of even what might seem to be simple queries can vary greatly. SSIS Connection time out settings do not affect command time outs.  Connection timeouts control how long the package will wait for a response from the server before assuming the server is not available or is not responding. Command time outs control how long a task will wait for results to start being returned before deciding that the server is not responding. Both lessons seem pretty straight forward, and I felt pretty sheepish once I finally figured out what the issue was.  To be fair though, In the 5+ years that I have been working with SSIS, I could only recall one other time where I had to set the CommandTimeout property, and that memory only resurfaced while I was penning this post.

  • How can I measure TCP timeout limit on NAT firewall for setting keepalive interval?

    - by jmanning2k
    A new (NAT) firewall appliance was recently installed at $WORK. Since then, I'm getting many network timeouts and interruptions, especially for operations which would require the server to think for a bit without a response (svn update, rsync, etc.). Inbound SSH sessions over VPN also timeout frequently. That clearly suggests I need to adjust the TCP (and ssh) keepalive time on the servers in question in order to reduce these errors. But what is the appropriate value I should use? Assuming I have machines on both sides of the firewall between which I can make a connection, is there a way to measure what the time limit on TCP connections might be for this firewall? In theory, I would send a packet with gradually increasing intervals until the connection is lost. Any tools that might help (free or open source would be best, but I'm open to other suggestions)? The appliance is not under my control, so I can't just get the value, though I am attempting to ask what it currently is and if I can get it increased.

  • svn-based versioning tool, problem with network timeout

    - by Scarlet
    My dev team was committed a versioning tool based on Subversion to run on Windows (our svn client is sliksvn). We're developing with Delphi XE2, should that matter. We're asked to implement a "check for updates availability" feature, which has to work as follows: Connect to the SVN repo via svn+ssh protocol; See if there are changes to receive and list them; Let the user decide if he wants to receive changes or not. We don't have a great knowledge on svn, so we thought to implement that thing client side by a certain number of CreateProcess calls that wrap directly proper svn commands. Anyways what we perceived is that if network problems should arise, such like a connection drop, svn client hangs forever waiting for the operation to close instead of failing for timeout. We know that CreateProcess can be given a timeout argument, but it wouldn't be correct to use it, as we can't know from outside how long will be the svn operation taking to complete. Is there any way to avoid that deadlock?

  • Intermittent timeout when connecting to Sql Server, what do I look for?

    - by Will
    Sql Server 2008 Standard 64bit on Windows Server 2008 R2 virtual machine hosted on a Hyper-V server. I'm getting intermittent timeouts when connecting to the server. This happens for both windows and Sql Authentication. May timeout every 2 out of 5 tries in different applications. When the connection times out, I can see (in Profiler) that no connection was made. Firewall is holey, server port is static (good ol' 1433). If I ping /t the server I get a steady connection that wavers between 1 and 2 ms. Any ideas what else to try would be appreciated, thanks.
