• Dynamic query to immediate execute?

  - by Curtis White

  I am using the MSDN Dynamic linq to sql package. It allows using strings for queries. But, the returned type is an IQueryable and not an IQueryable<T>. I do not have the ToList() method. How can I this immediate execute without manually enumerating over the IQueryable? My goal is to databind to the Selecting event on a linqtosql datasource and that throws a datacontext disposed exception. I can set the query as the Datasource on a gridview though. Any help greatly appreciated! Thanks. The dynamic linq to sql is the one from the samples that comes with visual studio.

• Python script run via cron does not execute occassionally

  - by gcorne

  I have a simple python script for fetching tweets and caching them to disk that is configured to run every two minutes via cron. */2 * * * * (date ; /usr/bin/python /path/get_tweets.py) >> /path/log/get_tweets.log 2>&1 The script runs successfully most of the time. However, every so often the script doesn't execute. In addition to other logging, I added a simple print statement above the meat of the script and nothing except the output from the initial date command makes it to the log. #!/usr/bin/python # Script for fetching tweets and then storing them as an HTML snippet for inclusion using SSI print "Starting get_tweets.py" Any ideas? The system is a VPS running Centos 5.3 with python 2.4.

• Execute VBA Macro via C# Interop?

  - by Jon Artus

  Hi all, just wondering if anyone could suggest why I might be getting an error? I'm currently trying to execute a macro in a workbook by calling the Application.Run method that the interop exposes. It's currently throwing the following COM Exception: {System.Runtime.InteropServices.COMException (0x800A03EC): Cannot run the macro Macro1'. The macro may not be available in this workbook or all macros may be disabled. I've put the containing workbook in a trusted location, set all of the security settings to their minimum values, and trusted programmatic access to my object model. I'm entirely out of ideas and Google's failed me so far! Has anyone done this, or can you suggest anything which I could try? Many thanks!

• Servlet doesnt appear to execute in a threaded manner

  - by RenegadeAndy

  I have developed a simple server using Tomcat which runs a servlet. The servlet calls a command line program - which takes about 20 seconds to execute then returns the result to the user via JSON. The problem is - if i make above 2 simultaneous requests, the servlet blocks until one of the previous requests is completed. An example of this can be seen below - "Im in" is the top of the servlet, and the list of results is after the servlet is executed. All requests were made at the same time - but you can clearly see they are not dealt with simultaneously. What setting do I need to change in tomcat in order to have all requests handeled at the same time? Thanks Andy Im in Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE Im in FVFNT01 STOP_IDLE FVFNT03 STOP_IDLE FVFNT16 STOP_IDLE FVFNT17 STOP_IDLE

• execute external command / application from java

  - by IttayD

  I'm looking for a package to support reliably executing external processes from Java. My criteria: Abstract over OS. So if I want to run 'foo', it will look for 'foo.bat', 'foo.exe' under windows and 'foo' under other OSs (or, have a way of passing a map of os-command) Being able to execute Java classes by simply giving the class name and arguments (so the package locates the java command, copies jvm flags and then executes) Process stdout and stderr properly Watchdog / Monitoring capabilities I've looked at commons-exec but it looks like it answers only 3 & 4. Ant has support for execution but looks like an overkill to use it for this purpose only.

• silently execute a MSI package from C#

  - by Keenan Molver

  Newbie question, let me try and make this as clear as possible. I have a program that needs to silently execute a msi package (well multiple but that's not the problem) The MSI packages are contained in a folder located in the same directory as my program. I've given it a simple name of "InstallFiles" for the time being. I'm not keen on using the full path name eg. C:\my program\another directory\another directory etc because it'll be put on multiple PC's, old and new, in which case the drive letter can change. So far I have: install.StartInfo.FileName = "msiexec"; install.StartInfo.Arguments = "/i F:\\InstallFiles\\JRE.msi"; install.Start(); install.WaitForExit(); However, when its launched it only gives me the Windows Installer switch information and then terminates, how do I get it to run and how would I go about changing the file path?

• Using directory traversal attack to execute commands

  - by gAMBOOKa

  Is there a way to execute commands using directory traversal attacks? For instance, I access a server's etc/passwd file like this http://server.com/..%01/..%01/..%01//etc/passwd Is there a way to run a command instead? Like... http://server.com/..%01/..%01/..%01//ls ..... and get an output? EDIT: To be clear here, I've found the vuln in our company's server. I'm looking to raise the risk level (or bonus points for me) by proving that it may give an attacker complete access to the system

• Execute code when Eclipse workbench loads

  - by Krt_Malta

  Hi! I'm writing an Eclipse plug-in and I've bumped into an issue. Amongst others I'm creating a new custom perspective. I need to execute some code when the workbench loads. I'm using a WorkbenchAdvisor and putting the code in the initialize method. However as it is now it's not being called... Apparently I need to call this PlatformUI.createAndRunWorkbench(display, new ApplicationWorkbenchAdvisor(); but I don't know where to put this... I can't put it in the createInitialLayout of the perspective because this is only called when the perspective is created for the first time. Any ideas please? Thanks and regards, Krt_Malta

• Javascript won't execute in iPhone Safari

  - by Stuart Meyer

  I'm running into this issue only because I recently purchased an iPhone. The javascript for a picture carousel on my website (http://www.stuartmeyerphotography.com) won't execute in Safari for iPhone. I thought it worked on Mac Safari last I checked with a friend who had a Mac (a year ago), but now I need to go back and check that too to make sure it works on the Mac. "View source" on my website would show the entire html page, but I've pulled the code from the body section to show here: carousel({id:'Photos', border:'', size_mode:'image', width:120, height:120, sides:8, steps:75, speed:4, direction:'left', images:['mainthumbs/babiesthumb.jpg','mainthumbs/engagementsthumb.jpg','mainthumbs/dancethumb1.jpg','mainthumbs/artistthumb.jpg','mainthumbs/portraitsthumb1.jpg','mainthumbs/seniorsthumb1.jpg','mainthumbs/wedthumb1.jpg'], links:['babies/babies.html','engagements/engagemainshow/engagementpictures.html','dance/dancepictures.html','artists/artists.html','portraits/portraits.html','seniors/highschoolseniors.html','weddings/weddings.html'], lnk_base:'', lnk_targets:['_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1' ], lnk_attr:['width=200,height=300,top=200,menubar=yes', 'width=300,height=200,left=400,scrollbars=yes', 'width=150,height=250,left=200,top=100', ''], titles:['Babies', 'Engagements', 'Dance', 'Artists', 'Portraits', 'HS Seniors', 'Weddings'], image_border_width:1, image_border_color:'#E3F0A1' });   </div> Any thoughts? -Stuart

• Execute SQL on CSV files via JDBC

  - by Markos Fragkakis

  Dear all, I need to apply an SQL query to CSV files (comma-separated text files). My SQL is predefined from another tool, and is not eligible to change. It may contain embedded selects and table aliases in the FROM part. For my task I have found two open-source (this is a project requirement) libraries that provide JDBC drivers: CsvJdbc XlSQL JBoss Teiid Create an Apache Derby DB, load all CSVs as tables and execute the query. These are the problems I encountered: it does not accept the syntax of the SQL (it uses internal selects and table aliases). Furthermore, it has not been maintained since 2004. I could not get it to work, as it has as dependency a SAX Parser that causes exception when parsing other documents. Similarly, no change since 2004. Have not checked if it supports the syntax, but seems like an overhead. It needs several entities defines (Virtual Databases, Bindings). From the mailing list they told me that last release supports runtime creation of required objects. Has anyone used it for such simple task (normally it can connect to several types of data, like CSV, XML or other DBS and create a virtual, unified one)? Can this even be done easily? From the 4 things I considered/tried, only 3 and 4 seem to me viable. Any advice on these, or any other way in which I can query my CSV files? Cheers

• Programatic re-evalutation of MVVM command's "can execute" state

  - by dzs

  Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

• Execute code on assembly load

  - by Dmitriy Matveev

  I'm working on wrapper for some huge unmanaged library. Almost every of it's functions can call some error handler deeply inside. The default error handler writes error to console and calls abort() function. This behavior is undesirable for managed library, so I want to replace the default error handler with my own which will just throw some exception and let program continue normal execution after handling of this exception. The error handler must be changed before any of the wrapped functions will be called. The wrapper library is written in managed c++ with static linkage to wrapped library, so nothing like "a type with hundreds of dll imports" is present. I also can't find a single type which is used by everything inside wrapper library. So I can't solve that problem by defining static constructor in one single type which will execute code I need. I currently see two ways of solving that problem: Define some static method like Library.Initialize() which must be called one time by client before his code will use any part of the wrapper library. Find the most minimal subset of types which is used by every top-level function (I think the size of this subset will be something like 25-50 types) and add static constructors calling Library.Initialize (which will be internal in that scenario) to every of these types. I've read this and this questions, but they didn't helped me. Is there any proper ways of solving that problem? Maybe some nice hacks available?

• Repeatedly execute a stored procedure

  - by manivineet

  I have a situation where I need to repeatedly execute a stored procedure Now this procedure (spMAIN) has a cursor inside which looks for a value from a table as T1,which has the following structure ID Status ---- -------- 1 New 2 New 3 success 4 Error now the cursor looks for all rows with a status of 'New' Now while processing , if that instance of the cursor encounters an error, another SP say spError needs to be called, the 'Status' column in T1 needs to be updated to 'Error' and spMAIN needs to be called again which again repeats the process, looking for rows with 'new' how do I do it? Also, also, while we are at it, what if an SP has other SPs inside it and if any of those SP raises an error, same thing needs to be done, the T1 table needs to be updated ('Error') and spMAIN needs to be called again. can you also recommend something ? here's some code ALTER PROC zzSpMain AS BEGIN DECLARE @id INT BEGIN TRY IF EXISTS ( SELECT * FROM dbo.zzTest WHERE istatus = 'new' ) BEGIN DECLARE c CURSOR FOR SELECT id FROM zztest WHERE istatus = 'new' OPEN c FETCH NEXT FROM c INTO @id WHILE @@FETCH_STATUS = 0 BEGIN PRINT @id IF @id = 2 BEGIN UPDATE zztest SET istatus = 'error' WHERE id = @id RAISERROR ( 'Error occured', 16, 1 ) END UPDATE zztest SET istatus = 'processed' WHERE id = @id FETCH NEXT FROM c INTO @id END CLOSE c DEALLOCATE c END END TRY begin CATCH EXEC zzSpError END CATCH END

• How can I execute a .sql from C#?

  - by J. Pablo Fernández

  For some integration tests I want to connect to the database and run a .sql file that has the schema needed for the tests to actually run, including GO statements. How can I execute the .sql file? (or is this totally the wrong way to go?) I've found a post in the MSDN forum showing this code: using System.Data.SqlClient; using System.IO; using Microsoft.SqlServer.Management.Common; using Microsoft.SqlServer.Management.Smo; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True"; FileInfo file = new FileInfo("C:\\myscript.sql"); string script = file.OpenText().ReadToEnd(); SqlConnection conn = new SqlConnection(sqlConnectionString); Server server = new Server(new ServerConnection(conn)); server.ConnectionContext.ExecuteNonQuery(script); } } } but on the last line I'm getting this error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.TypeInitializationException: The type initializer for '' threw an exception. --- .ModuleLoadException: The C++ module failed to load during appdomain initialization. --- System.DllNotFoundException: Unable to load DLL 'MSVCR80.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). I was told to go and download that DLL from somewhere, but that sounds very hacky. Is there a cleaner way to? Is there another way to do it? What am I doing wrong? I'm doing this with Visual Studio 2008, SQL Server 2008, .Net 3.5SP1 and C# 3.0.
