  • How to get a list of users for all instance's databases

    - by stee1rat
    I guess the procedure should be something like this: declare @db varchar(100) declare @user varchar(100) declare c cursor for select name from sys.sysdatabases open c fetch next from c into @db while @@fetch_status = 0 begin print @db exec ('use ' + @db) declare u cursor for select name from sys.sysusers where issqlrole <> 1 and hasdbaccess <> 0 and isntname <> 1 open u fetch next from u into @user while @@fetch_status = 0 begin print @user fetch next from u into @user end print '--------------------------------------------------' close u deallocate u fetch next from c into @db end close c deallocate c But the problem is that exec ('use ' + @db) doesn't work. And i always get user list of currently chosen database. How should i fix that? P.S.: I want this code to work on both 2000 and 2005 sql servers.

  • Javascript: why I cannot load my external js page in Drupal ?

    - by Patrick
    hi, when I add the tag script to load an external javascript file, my page is not longer displayed. There are not error in Firebug, there are not errors such as "File not found" or "Not enough permissions", the browser just displays a blank page for some reason. <?php print $head; ?> <?php print $styles; ?> <?php print $scripts; ?> <script type="text/JavaScript" src="main.js" /> If I remove the last line everything works perfectly. The previous php lines are the standard Drupal head lines. This is the content of my js file: $(document).ready( function() { alert("hello"); }); thanks

  • Loop through collections

    - by ScG
    I have two classes class A { public string something { get; set; } public IList<B> b= new List<B>(); } class B { public string else { get; set; } public string elseelse { get; set; } } I have populated an object of class A called obj. How can I loop through this object and print values. Do I have to use two foreach's like the one show here or is there a better way? foreach (var z in obj) { // print z.something; foreach (var x in z.b) { // print x.elseelse; } }

  • Why is the value of __name__ changing after assignment to sys.modules[__name__]?

    - by martineau
    While trying to do something similar to what's in the ActiveState recipe titled Constants in Python by Alex Martelli, I ran into an unexpected side-effect that assigning a class instance to an entry in sys.modules apparently has in Python 2.7 -- namely that doing so apparent changes the value of __name__ to None as illustrated in the following code fragment: class _test(object): pass import sys print '__name__: %r' % __name__ # __name__: '__main__' sys.modules[__name__] = _test() print '__name__: %r' % __name__ # __name__: None if __name__ == '__main__': # never executes... import test print "done" I'd like to understand why this is happening. I don't believe it was that way in Python 2.6 and earlier versions since I have some older code where apparently the if __name__ == '__main__': conditional worked as expected following the assignment (but no longer does). FWIW, I also noticed that the name _class is getting rebound from a class object to None, too, after the assignment. Also seems odd to me that they're being rebound to 'None' rather than disappearing altogether... Update: I'd like to add that any workarounds for achieving the effect of if __name__ == '__main__':, given what happens would be greatly appreciated. TIA!

  • How do I get MSBuild Task to generate XML Documents when building a solution?

    - by toba303
    I have a solution with lots of projects. Each project is configured to generate the XML documentation file when building in Debug-Mode (which is default). That works when I build in Visual Studio 2008. In my build script on my integration server I advise MSBuild to build the whole solution, but it won't generate the documentation files. What can I do? I already tried to explicitly give the Debug-Condition to the build process, but it makes no difference. <Target Name="BuilSolution"> <MSBuild Projects="C:\Path\To\MySolution.sln" targets="Build" Properties="SolutionConfigurationPlatforms='Debug|Any CPU'"/> </Target> There seem to be some ideas to solve this problem when building single projects, but I can't afford to do this, so I need a hint for doing it this way. Thanks in advance!

  • Deferred printing in Java

    - by Bober02
    I have a specific issue with general console printing and I was wondering whether anyone has a solution for it. I am trying to print a dataTable which would look like sth like this: Table ---------------------- Name |Surname | ---------------------- Mike |Mikhailowish| Rafaello|Mirena | and so on. In order to print the border of the bar I need to know what the maximum length of each column value is. I don't want to go through the whole database to find that out and then again to print it. I would rather like to do sth like: System.out.printLater(s); //herejust leave a pointer to a StringBuilder you will build ... s.append("--------"); ... System.out.printAllDeferred(); I understand the above is probably in 99.99999% chances impossible, but perhaps you guys have a clever way of achieving the above?

  • What could cause a returning function to crash? C++

    - by JeanOTF
    So I have been debugging this error for hours now. I writing a program using Ogre3d relevant only because it doesn't load symbols so it doesn't let me stack trace which made finding the location of the crash even harder. So, write before I call a specific function I print out "Starting" then I call the function and immediately after I print "Stopping". Throughout the function I print out letters A-F where F is printed right before the function returns (one line above the last '}') The weird thing is when the crash occurs it is after the 'F' is printed but there is no 'Stopping'. Does this mean that the crash is happening in between somewhere? The only thing I can think of is something going wrong during the deallocation of some of the memory allocated during the function. I've never had anything happen like this, I will keep checking to make sure it's going wrong where I think it is.

  • Flattening hash into string in Ruby

    - by fahadsadah
    Is there a way to flatten a hash into a string, with optional delimiters between keys and values, and key/value pairs? For example, print {:a => :b, :c => :d}.flatten('=','&') should print a=b&c=d I wrote some code to do this, but I was wondering if there was a neater way: class Hash def flatten(keyvaldelimiter, entrydelimiter) string = "" self.each do |key, value| key = "#{entrydelimiter}#{key}" if string != "" #nasty hack string += "#{key}#{keyvaldelimiter}#{value}" end return string end end print {:a => :b, :c => :d}.flatten('=','&') #=> 'c=d&a=b' Thanks

  • How to get "printer ready bytes" from a source in c#?

    - by luis_villase
    Hey everyone! I'm in a bit of trouble here, hoping you can help a fellow programmer out. I have an application that receives a pointer to raw bytes (plus length and stuff) and sends said raw data to a printer. This is important, I have no choice but to use this method to get any printing done. If I send a raw string, it will print with no problem. However, I need to be able to print formatted text, images, etc. So the thing is... I would like to be able to get printer ready bytes from a given source (maybe a pdf, or html, does not matter as long as it contains formatted text and/or images). It would be like "splitting" the print command like so: a) Open file and read data b) Load printer data into memory c) Send bytes to printer Obviously, I've got a) and c) covered, it's b) the one that's breaking my head. Any thoughts? Thanks in advance for your help.

  • How do I tell gdb how long my zero-length array is?

    - by Joe
    Slightly oxymoronic title! Bonus points for Xcode answer but it's a gdb question. If I have a standard, statically sized array gdb will print all its elements [and Xcode will let me browse through it] but if I have a zero length array, it won't, because it doesn't know. Obviously I can print the array indexes one by one, but I'd like a dump of the whole thing. How do I tell gdb how much space I have allocated for the array to allow it to print the array (or to allow Xcode to view the array). Is it even possible?

  • Visual C++ application/libarary size anomoly

    - by Tim Ring
    This is just a bit of a general question regading app/lib file sizes. When I build a particular library in my C++ solution I notice that the .lib file size is larger in the release build than in the debug (1.2mb Vs 800k). However when I build an app in the same solution, using the aforementioned library, the release .exe is always smaller (as I'd expect) than thew debug .exe (50k vs 200k). I would always have expected the release verisons of anything to be smaller than the debug versions. What gives?

  • Output custom messages based on row value

    - by decimal
    I've made a simple guestbook mysql/php page. An entry is displayed if the approve column has a value of 1. For the adminstrator, I want to display either "message approved" or "not approved". Here's my code: while ($row = mysql_fetch_array ($r)) { print "<p>Guest:" .$row['name']. "</p> <p>Date:" .$row['date']. "</p> <p>Comment:". $row['comment']. "</p>"; if ($row['approve'] = '1') { print '<p>YES, the message has been approved</p>'; } else { print '<p>NO, it hasn\'t been approved</p>'; } Whatever value the if statement checks approve is equal to, all approve values are output as that value.

What change is needed to be made?

  • Reason for unintuitive UnboundLocalError behaviour 2

    - by Jonathan
    Following up on Reason for unintuitive UnboundLocalError behaviour (I will assume you've read it). Consider the following Python script: def f(): # a+=1 # 1 aa=a aa+=1 # b+='b' # 2 bb=b bb+='b' c[0]+='c' # 3 c.append('c') cc=c cc.append('c') # 4 a=1 b='b' c=['c'] f() print a print b print c The result of the script is: 1 b ['cc', 'c', 'c'] The commented out lines (marked 1,2) are lines that would through an UnboundLocalError and the SO question I referenced explains why. However, the line marked 3 works! By default, lists are copied by reference in Python, therefore it's understandable that c changes when cc changes. But why should Python allow c to change in the first place, if it didn't allow changes to a and b directly from the method's scope? I don't see how the fact that by default lists are copied by reference in Python should make this design decision inconsistent. What am I missing folks?

  • autofac's Func<T> to resolve named service

  • SqlAlchemy hangs after adding record in MS SQL

    - by Patrick
    I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?

  • create logging so that the messages will be displayed on screen and logged to a file

    - by robUK
    Hello, gcc 4.4.4 c89 I am writing a client/server application. I have finished and now I want to implement some logging feature that will display log messages on the screen as well as log to a file. However, I don't want to display all log messages (warning, error, critical, unrecoverable, debug, etc). Maybe I can set so that it will display, just errors and debug messages and nothing else. For example, the user might not be interested in the debug messages. Is there any design-pattern that I can follow? What do you normally for for logging? Any tutorials out there that address logging? many thanks for any suggestions,

  • How to get variable value from inside a stored procedure in DB2?

    - by Sylvia
    This seems like it should be very easy...anyway, it is in MS SQL Server In a DB2 stored procedure, how can I just get the value of a variable? Say I have the following stored procedure: CREATE PROCEDURE etl.TestABC( ) LANGUAGE SQL BEGIN declare Stmt varchar(2048); set Stmt = 'this is a test'; -- print Stmt; -- select Stmt; return 0; END @ I'd like to print out the value of Stmt after I set it. Print doesn't work, select doesn't work. Somebody said I have to insert it to a table first, and then get it after I run the stored procedure. Is this really necessary? Thanks, Sylvia EDIT: I should have made clearer that I want to see the value of Stmt each time after I set it, and I may need to set it multiple times within the same stored procedure.

  • Location inheritInChildApplications kill debugger?

    Hi I am wondering is this normal when you add this into your web.config <location path="." inheritInChildApplications="false"> </location> The debugger should stop working. Like when I add this to my site and try to run in debug mode it won't activate any of my debug points nor will it lock up Visual studios 2008. I can have it running and still make edits to my C# code. I take the line away and I get the debug mode back and it locks up VS2008.

  • Crystal Report | Printing | Default Printer

    - by Akshay J
    I am making one application where user will print invoices which I am displaying using Crystal Report. The user showed me his current application made using ForPro. In that application, under Printer Options form, one can see all the printers currently installed and the user could select default printer. When the invoice is made, the user presses the print button, then there is one dialog asking for no. of copies. When it's entered, the invoice gets printed directly, without any Print Dialog Box. If the user wants to change the printer again he/she will change it in the Printer Option form. I want to know if similar thing is possible in Crystal Report and need guidance on how to approach for it.

  • How to get a variable name as a string in Python?

    - by e-satis
    I would like to be able to get the name of a variable as a string but I don't know if Python has that much introspection capabilities. Something like: >>> print(my_var.__name__) 'my_var' I want to do that because I have a bunch of vars I'd like to turn into a dictionary like : bar=True foo=False >>> my_dict=dict(bar=bar, foo=foo) >>> print mydict >>> print my_dict {'foo': False, 'bar': True} But I'd like something more automatic than that. Python have locals() and vars(), so I guess there is a way.
