  • Minimum privileges to read SQL Jobs using SQL SMO

    - by Gustavo Cavalcanti
    I wrote an application to use SQL SMO to find all SQL Servers, databases, jobs and job outcomes. This application is executed through a scheduled task using a local service account. This service account is local to the application server only and is not present in any SQL Server to be inspected. I am having problems getting information on job and job outcomes when connecting to the servers using a user with dbReader rights on system tables. If we set the user to be sysadmin on the server it all works fine. My question to you is: What are the minimum privileges a local SQL Server user needs to have in order to connect to the server and inspect jobs/job outcomes using the SQL SMO API? I connect to each SQL Server by doing the following: var conn = new ServerConnection { LoginSecure = false, ApplicationName = "SQL Inspector", ServerInstance = serverInstanceName, ConnectAsUser = false, Login = user, Password = password }; var smoServer = new Server (conn); I read the jobs by reading smoServer.JobServer.Jobs and read the JobSteps property on each of these jobs. The variable server is of type Microsoft.SqlServer.Management.Smo.Server. user/password are of the user found in each SQL Server to be inspected. If "user" is SysAdmin on the SQL Server to be inspected all works ok, as well as if we set ConnectAsUser to true and execute the scheduled task using my own credentials, which grants me SysAdmin privileges on SQL Server per my Active Directory membership. Thanks!

  • Best way for launching html/jsp to communicate with GWT module

    - by h2g2java
    I asked this at the GWT forum but I'm impatient for the answer and I seem to get rather good responses here. A html or jsp file is used to launch the xxx.nocache.js, which then decides which browser "permutation" to use. <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8"> <title>xxx</title> <script type="text/javascript" language="javascript" src="xxx.nocache.js"></script> </head> In my case, I am using a jsp. When the JSP is executed, it discovers some conditions. I wish to pass these conditions as values to the GWT module being launched. The "elegant" GWT way to pass these values would be to persist them as request/memcache attributes and then have the GWT module perform RPC to retrieve those values. For example, the JSP discovers that the current user is Whoopy. Shouldn't I simply have the JSP generate javascript to store user = "Whoopy" as a top or namedframe level javascript variable and use JSNI within the module to retrieve the value for user? I have not tried it yet, but I would like to know how anyone might have done it without having to use RPC.

  • Calculating bounding box a certain distance away from a lat/long coordinate in Java

    - by Bryce Thomas
    Given a coordinate (lat, long), I am trying to calculate a square bounding box that is a given distance (e.g. 50km) away from the coordinate. So as input I have lat, long and distance and as output I would like two coordinates; one being the south-west (bottom-left) corner and one being the north-east (top-right) corner. I have seen a couple of answers on here that try to address this question in Python, but I am looking for a Java implementation in particular. Just to be clear, I intend on using the algorithm on Earth only and so I don't need to accommodate a variable radius. It doesn't have to be hugely accurate (+/-20% is fine) and it'll only be used to calculate bounding boxes over small distances (no more than 150km). So I'm happy to sacrifice some accuracy for an efficient algorithm. Any help is much appreciated. Edit: I should have been clearer, I really am after a square, not a circle. I understand that the distance between the center of a square and various points along the square's perimeter is not a constant value like it is with a circle. I guess what I mean is a square where if you draw a line from the center to any one of the four points on the perimeter that results in a line perpendicular to a side of the perimeter, then those 4 lines have the same length.

  • Creating spotlight in OpenGL scene

    - by Victor Oliveira
    Im studying OpenGL and trying to create a spot light at my application. The code that Im using for my #vertex-shader is below: #:vertex-shader #{ #version 150 core in vec3 in_pos; in vec2 in_tc; out vec2 tc; glLightf(GL_LIGHT0, GL_SPOT_CUTOFF, 20.0f); GLfloat spot_direction[] = { -1.0, -1.0, 0.0 }; glLightfv(GL_LIGHT0, GL_SPOT_DIRECTION, spot_direction); glEnable(GL_LIGHT0); void main() { vec4 pos= vec4(vec3(1.0)*in_pos - vec3(1.0), 1.0); pos.z=0.0; gl_Position = pos; tc = in_tc; } } The thing is, everytime Im trying to run the code an Error that says: Type: other, Source: api, ID: 131169, Severity: low Message: Framebuffer detailed info: The driver allocated storage for renderbuffer 1. len = 157, written = 0 failed to compile vertex shader of deferred: directional info log for shader deferred: directional vertex info log for shader deferred: directional: ERROR: Unbound variable: when Specifications: Renderer: GeForce GTX 580/PCIe/SSE2 Version: 3.3.0 NVIDIA 319.17 GLSL: 3.30 NVIDIA via Cg compiler Status: Using GLEW 1.9.0 1024 x 768 OS: Linux debian I guess to create this spotlight is pretty much simple, but since Im really new to OpenGL I dont have a clue how to do it until now, even reading sources like: http://www.glprogramming.com/red/chapter05.html#name3 Read also in some place that light spots can get really hard to understand, but I cant avoid this step right now since Im following my lecture schedule.

  • matching an element's class to another element's ID, or *part* of another element's ID

    - by shecky
    hello again Such a simple concept but I'm struggling to express it ... apologies in advance for my verbosity. I have a container div with a class, e.g., ; I want to use that class to do two things: add a class (e.g., 'active') to the nav element whose ID matches the class of div#container (e.g., #nav-primary li# apples) add the same class to another element if part of this element's ID matches the class of #container (e.g., div#secondary-apples) I assume there's an .each() loop to check the primary nav's list items' IDs, and to check the div IDs of the secondary nav ... though the latter needs to have its prefix trimmed ... or should I say more simply if the secondary nav div IDs contain the class of div#container? I've tried a few variations of something like this: <script type="text/javascript"> $(document).ready(function() { $('#nav-primary li').each(function(){ var containerClass = $('#container').attr('class'); var secondaryID = $('#nav-primary li').attr('id'); // something like if ('#nav-primary li id' == (containerClass) { } // or should I first store a variable of the LI's ID and do something like this: if ( secondaryID == containerClass ) { } // and for the trickier part, how do I filter/trim the secondary nav div IDs, something like this: var secondaryNavID = $('#aux-left div[id ... something here to strip the 'secondary-' bit ... ]'); }); // end each }); // end doc.ready.func </script> The markup is, e.g.: ... ... ... ... ... ... ... Many thanks in advance for any suggestions, svs

  • C++ Returning a Reference

    - by Devil Jin
    Consider the following code where I am returning double& and a string&. The thing works fine in the case of a double but not in the case of a string. Why is this difference in the behavior? In both the cases compiler does not even throws the Warning: returning address of local variable or temporary as I am returning a reference. #include <iostream> #include <string> using namespace std; double &getDouble(){ double h = 46.5; double &hours = h; return hours; } string &getString(){ string str = "Devil Jin"; string &refStr = str; return refStr; } int main(){ double d = getDouble(); cout << "Double = " << d << endl; string str = getString(); cout << "String = " << str.c_str() << endl; return 0; } Output: $ ./a.exe Double = 46.5 String =

  • How can I extend this SQL query to find the k nearest neighbors?

    - by Smigs
    I have a database full of two-dimensional data - points on a map. Each record has a field of the geometry type. What I need to be able to do is pass a point to a stored procedure which returns the k nearest points (k would also be passed to the sproc, but that's easy). I've found a query at http://blogs.msdn.com/isaac/archive/2008/10/23/nearest-neighbors.aspx which gets the single nearest neighbour, but I can't figure how to extend it to find the k nearest neighbours. This is the current query - T is the table, g is the geometry field, @x is the point to search around, Numbers is a table with integers 1 to n: DECLARE @start FLOAT = 1000; WITH NearestPoints AS ( SELECT TOP(1) WITH TIES *, T.g.STDistance(@x) AS dist FROM Numbers JOIN T WITH(INDEX(spatial_index)) ON T.g.STDistance(@x) < @start*POWER(2,Numbers.n) ORDER BY n ) SELECT TOP(1) * FROM NearestPoints ORDER BY n, dist The inner query selects the nearest non-empty region and the outer query then selects the top result from that region; the outer query can easily be changed to (e.g.) SELECT TOP(20), but if the nearest region only contains one result, you're stuck with that. I figure I probably need to recursively search for the first region containing k records, but without using a table variable (which would cause maintenance problems as you have to create the table structure and it's liable to change - there're lots of fields), I can't see how.

  • Using libcurl to create a valid POST

Therefore I'm expecting the buffer to be one or the other, however I seem to only be returning 0 or equivalent. Does the code above look like it will return what I expect or should my variable types be different? The conversion using "atoi" may be an issue. Any thought would be much appreciated.

  • UIViewController remaining

    - by Guy
    Hi Guys. I have a UIViewController named equationVC who's user interface is being programmatically created from another NSObject class called equationCon. Upon loading equationVC, a method called chooseInterface is called from the equationCon class. I have a global variable (globalVar) that points to a user defined string. chooseInterface finds a method in the equationCon class that matches the string globalVar points to. In this case, let's say that globalVar points to a string that is called "methodThatMatches." In methodThatMatches, another view controller needs to show the results of what methodThatMatches did. methodThatMatches creates a new equationVC that calls upon methodThatMatches2. As a test, each method changes the color of the background. When the application starts up, I get a purple background, but as soon as I hit backwards I get another purple screen, which should be yellow. I do not think that I am release the view properly. Can anyone help? -(void)chooseInterface { NSString* equationTemp = [globalVar stringByReplacingOccurrencesOfString:@" " withString:@""]; equationTemp = [equationTemp stringByReplacingOccurrencesOfString:@"'" withString:@""]; SEL equationName = NSSelectorFromString(equationTemp); NSLog(@"selector! %@",NSStringFromSelector(equationName)); if([self respondsToSelector:equationName]){ [self performSelector:equationName]; } } -(void)methodThatMatches{ self.equationVC.view.backgroundColor = [UIColor yellowColor]; [setGlobalVar:@"methodThatMatches2"]; EquationVC* temp = [[EquationVC alloc] init]; [[self.equationVC navigationController] pushViewController:temp animated:YES ]; [temp release]; } -(void)methodThatmatches2{ self.equationVC.view.backgroundColor = [UIColor purpleColor]; }

  • is this uibutton autoreleased ?

    - by dubbeat
    HI This is just a question to check my sanity really. I'm hunting memory leaks that show up in instruments but not the static analyzer. In one spot the analyzer is pointing to this block of code UIButton *randomButton = [UIButton buttonWithType:UIButtonTypeRoundedRect ]; randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button [randomButton setTitle:@"Random" forState:UIControlStateNormal]; randomButton.backgroundColor = [UIColor clearColor]; randomButton.adjustsImageWhenHighlighted = YES; [randomButton addTarget:self action:@selector(getrandom:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:randomButton]; For some reason I thought the above code would auto release the button because I'm not calling init or alloc? If I add [randombutton release] at the bottom of the code my button fails to show. Could somebody describe to me the correct way to release a button from memory that is created in the above way? Or would I be better off making the button a class variable and sticking the release in the dealloc method?

But I cannot impose IF (room_id IS NOT NULL) THEN since it will create KeyToBin('') and RoomKey is foreign key , KeyToBin('') will produce an invalid RoomKey. Any Idea?

  • How to add text to email sent from a php contact form

    Hi all this is the PHP im using: <?php $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $message = $_POST['message']; $formcontent=" From: $name \n Phone: $phone \n Message: $message"; $recipient = "[email protected]"; $subject = "Contact Form"; $mailheader = "From: $email \r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none; color:#ff0099;'> Return Home</a>"; ?> Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the: mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); line but with no success. Thanks for taking the time any help would be welcome.

  • how do i work bool!

    - by user350217
    HI! im a beginner and im really getting frustrated with this whole concept. i dont understand how to exactly use the bool function. i know what it is but i cantfigure out how to make it work in my program. Im trying to say that if my variable "selection" is any letter beween 'A' and 'I' then it is valid and can continue on to the next function which is called calcExchangeAmt(amtExchanged, selection). if it is false i want it to ask the user if they want to repeat the program and if they agree to repeat i want it to clear the screen and restart to the main function. please help edit my work! this is my bool function: bool isSelectionValid(char selection, char yesNo, double amtExchanged) { bool validData; validData = true; if((selection >= 'a' && selection <= 'i') || (selection >= 'A' && selection <= 'I')) { validData = calcExchangeAmt (amtExchanged, selection); } else(validData == false); { cout<<"Do you wish to continue? (Y for Yes / N for No)"; cin>>yesNo; } do { main(); } while ((yesNo =='y')||(yesNo == 'Y')); { system("cls"); } return 0; } this is the warning that im gettng: warning C4800: 'double' : forcing value to bool 'true' or 'false' (performance warning)

  • Grails UrlMappings with .html

    - by Glennn
    I'm developing a Grails web application (mainly as a learning exercise). I have previously written some standard Grails apps, but in this case I wanted to try creating a controller that would intercept all requests (including static html) of the form: <a href="/testApp/testJsp.jsp">test 1</a> <a href="/testApp/testGsp.gsp">test 2</a> <a href="/testApp/testHtm.htm">test 3</a> <a href="/testApp/testHtml.html">test 4</a> The intent is to do some simple business logic (auditing) each time a user clicks a link. I know I could do this using a Filter (or a range of other methods), however I thought this should work too and wanted to do this using a Grails framework. I set up the Grail UrlMappings.groovy file to map all URLs of that form (/$myPathParam?) to a single controller: class UrlMappings { static mappings = { "/$controller/$action?/$id?"{ constraints { } } "/$path?" (controller: 'auditRecord', action: 'showPage') "500"(view:'/error') } } In that controller (in the appropriate "showPage" action) I've been printing out the path information, for example: def showPage = { println "params.path = " + params.path ... render(view: resultingView) } The results of the println in the showPage action for each of my four links are testJsp.jsp testGsp.gsp testHtm.htm testHtml Why is the last one "testHtml", not "testHtml.html"? In a previous (Stack Overflow query) Olexandr encountered this issue and was advised to simply concatenate the value of request.format - which, indeed, does return "html". However request.format also returns "html" for all four links. I'm interested in gaining an understanding of what Grails is doing and why. Is there some way to configure Grails so the params.path variable in the controller shows "testHtml.html" rather than stripping off the "html" extension? It doesn't seem to remove the extension for any other file type (including .htm). Is there a good reason it's doing this? I know that it is a bit unusual to use a controller for static html, but still would like to understand what's going on.

  • How to create a CGBitmapContext which works for Retina display and not wasting space for regular display?

    - by ????
    Is it true that if it is in UIKit, including drawRect, the HD aspect of Retina display is automatically handled? So does that mean in drawRect, the current graphics context for a 1024 x 768 view is actually a 2048 x 1536 pixel Bitmap context? (is there a way to print this size out to verify it). We actually enjoy the luxury of 1 point = 4 pixels automatically handled for us. However, if we use CGBitmapContextCreate, then those will really be pixels, not points? (at least if we provide a data buffer for that bitmap, the size is not for the higher resolution, but for the standard resolution, and even if we pass NULL as the buffer so that CGBitmapContextCreate handles the buffer for us, the size probably is the same as if we pass in a data buffer, and it is just standard resolution, not Retina's resolution). We can always create 2048 x 1536 for iPad 1 and iPad 2 as well as the New iPad, but it will waste memory and processor and GPU power, as it is only needed for the New iPad. So do we have to use a if () { } else { } to create such a bitmap context and how do we actually do so? And all our code CGContextMoveToPoint has to be adjusted for Retina display to use x * 2 and y * 2 vs non-retina display of just using x, y as well? That can be quite messy for the code. (or maybe we can define a local variable scaleFactor and set it to 1 for standard resolution and 2 if it is retina, so our x and y will always be x * scaleFactor, y * scaleFactor instead of just x and y.) It seems that UIGraphicsBeginImageContextWithOptions can create one for Retina automatically if the scale of 0.0 is passed in, but I don't think it can be used if I need to create the context and keep it (and using ivar or property of UIViewController to hold it). If I don't release it using UIGraphicsEndImageContext, then it stays in the graphics context stack, so it seems like I have to use CGBitmapContextCreate instead. (or do we just let it stay at the bottom of the stack and not worry about it?)

  • Flex wordwrap issue with multiple text instances

    - by Craig Myles
    Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  • How can I fix this clang warning: "Object with +0 retain counts returned to caller where +1 (owning)

    - by mipadi
    I have a piece of Objective-C code that looks like the following: - (NSString *)copyData:(NSData *)data { NSString *path = [[[self outputDirectory] stringByAppendingPathComponent:@"archive"] stringByAppendingPathExtension:@"zip"]; NSLog(@"Copying data to %@", path); [data writeToFile:path atomically:NO]; return path; } The code is called from an initializer that looks like this: - (id)initWithData:(NSData *)data { if ((self = [super init]) != nil) { NSString *path = [self copyData:data]; // Line 41 (referenced in warning, shown below) return [self initWithContentsOfFile:path]; } return self; } When running the clang static analyzer, I get the following warnings for the path variable: Potential leak of an object allocated on line 41 and stored into 'path' Object with +0 retain counts returned to caller where +1 (owning) retain count is expected I'm confused. My understanding is that stringByAppendingPathComponent should not return an autoreleased string, so it should have a net retain count of 0. (Obviously I don't want to retain it.) I've tried altering copyData: to return the following, but it didn't get rid of the warning: return [[path retain] autorelease]; So what's the deal with this warning?

  • Improve performance of searching JSON object with jQuery

    - by cale_b
    Please forgive me if this is answered on SO somewhere already. I've searched, and it seems as though this is a fairly specific case. Here's an example of the JSON (NOTE: this is very stripped down - this is dynamically loaded, and currently there are 126 records): var layout = { "2":[{"id":"40","attribute_id":"2","option_id":null,"design_attribute_id":"4","design_option_id":"131","width":"10","height":"10", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}, {"id":"41","attribute_id":"2","option_id":"115","design_attribute_id":"4","design_option_id":"131","width":"2","height":"1", "repeat":"0","top":"0","left":"0","bottom":"4","right":"2","use_right":"0","use_bottom":"0","apply_to_options":"0"}, {"id":"44","attribute_id":"2","option_id":"118","design_attribute_id":"4","design_option_id":"131","width":"10","height":"10", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}], "5":[{"id":"326","attribute_id":"5","option_id":null,"design_attribute_id":"4","design_option_id":"154","width":"5","height":"5", "repeat":"0","top":"0","left":"0","bottom":"0","right":"0","use_right":"0","use_bottom":"0","apply_to_options":"0"}] }; I need to match the right combination of values. Here's the function I currently use: function drawOption(attid, optid) { var attlayout = layout[attid]; $.each(attlayout, function(k, v) { // d_opt_id and d_opt_id are global scoped variable set elsewhere if (v.design_attribute_id == d_att_id && v.design_option_id == d_opt_id && v.attribute_id == attid && ((v.apply_to_options == 1 || (v.option_id === optid)))) { // Do stuff here } }); } The issue is that I might iterate through 10-15 layouts (unique attid's), and any given layout (attid) might have as many as 50 possibilities, which means that this loop is being run A LOT. Given the multiple criteria that have to be matched, would an AJAX call work better? (This JSON is dynamically created via PHP, so I could craft a PHP function that could possibly do this more efficently), or am I completely missing something about how to find items in a JSON object? As always, any suggestions for improving the code are welcome! EDIT: I apologize for not making this clear, but the purpose of this question is to find a way to improve the performance. The page has a lot of javascript, and this is a location where I know that performance is lower than it could be.

I have installed pear image_graphviz package(Image_GraphViz-1.2.1), I also installed graphviz.msi(Graphviz2.25.msi) in windows(But i don't know if does something with image_graphviz and if it does have some effects when i use image_graphviz). Do i need to do something else? Here is my code from pear image_graphviz site. <?php require_once 'Image/GraphViz.php'; error_reporting(E_ALL ^ E_NOTICE); //Added E_NOTICE $gv = new Image_GraphViz(); $gv->addEdge(array('wake up' => 'visit bathroom')); $gv->addEdge(array('visit bathroom' => 'make coffee')); $gv->image(); ?> This is the warning: Warning: fopen(C:\WINDOWS\Temp\gra50.tmp.svg) [function.fopen]: failed to open stream: No such file or directory in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 210 Notice: Undefined variable: data in C:\wamp\bin\php\php5.3.0\PEAR\Image\GraphViz.php on line 218 Thanks Pekka Gaiser, I used error_reporting(E_ALL ^ E_NOTICE);. I don't know how to change the temp directory, but c:/windows/temp exists in my computer. I haven't solve the problem. Thanks all for advice.

  • strange behavior in python

    - by fsm
    The tags might not be accurate since I am not sure where the problem is. I have a module where I am trying to read some data from a socket, and write the results into a file (append) It looks something like this, (only relevant parts included) if __name__ == "__main__": <some init code> for line in file: t = Thread(target=foo, args=(line,)) t.start() while nThreads > 0: time.sleep(1) Here are the other modules, def foo(text): global countLock, nThreads countLock.acquire() nThreads += 1 countLock.release() """connect to socket, send data, read response""" writeResults(text, result) countLock.acquire() nThreads -= 1 countLock.release() def writeResults(text, result): """acquire file lock""" """append to file""" """release file lock""" Now here's the problem. Initially, I had a typo in the function 'foo', where I was passing the variable 'line' to writeResults instead of 'text'. 'line' is not defined in the function foo, it's defined in the main block, so I should have seen an error, but instead, it worked fine, except that the data was appended to the file multiple times, instead of being written just once, which is the required behavior, which I got when I fixed the typo. My question is, 1) Why didn't I get an error? 2) Why was the writeResults function being called multiple times?

  • How does an NSTextField know that it's value has changed?

    - by Brian Postow
    I have a textfield that can either be edited by hand, or set through another control. (It's a page number, so you can jump to page 16 by typing in 16, or you can page up and down with the next/prev buttons) I have the value of the text field bound to an int page variable. It seems to work correctly, when you type a page number in, it jumps, when you page up and down, the page number in the text box changes appropriately. However, at some level, when I page up and down, the text box doesn't seem to know that it's value has changed, because if I type 1 it doesn't do anything. It doesn't call the bound set-method or anything. It looks like the textfield is thinking "I'm already 1, so I don't need to do anything." Even though it was 5 because I hit next 4 times. If I type an number other than 1, it goes there. If I THEN type 1, it goes to page 1, because now it thinks it's on that other page. The problem seems to be that I'm changing the value of the textfield programatically, but some part isn't getting the message. Does this seem like a reasonable explanation? And either way, any ideas on what's causing it? thanks

  • phppgadmin : How does it kick users out of postgres, so it can db_drop?

    - by egarcia
    I've got one Posgresql database (I'm the owner) and I'd like to drop it and re-create it from a dump. Problem is, there're a couple applications (two websites, rails and perl) that access the db regularly. So I get a "database is being accessed by other users" error. I've read that one possibility is getting the pids of the processes involved and killing them individually. I'd like to do something cleaner, if possible. Phppgadmin seems to do what I want: I am able to drop schemas using its web interface, even when the websites are on, without getting errors. So I'm investigating how its code works. However, I'm no PHP expert. I'm trying to understand the phppgadmin code in order to see how it does it. I found out a line (257 in Schemas.php) where it says: $data->dropSchema(...) $data is a global variable and I could not find where it is defined. Any pointers would be greatly appreciated.

  • Should I release NSString before assigning a new value to it?

    - by Elliot Chen
    Hi, Please give me some suggestions about how to change a NSString variable. At my class, I set a member var: NSString *m_movieName; ... @property(nonatomic, retain) NSString *m_movieName; At viewDidLoad method, I assign a default name to this var: -(void)viewDidLoad{ NSString *s1 = [[NSString alloc] initWithFormat:@"Forrest Gump"]; self.m_movieName = s1; ... [s1 release]; [super viewDidLoad] } At some function, I want to give a new name to this var, so I did like: -(void)SomeFunc{ NSString *s2 = [[NSString alloc] initWithFormat:@"Brave Heart"]; //[self.movieName release]; // ??????? Should perform here? self.m_moiveName = s2; [s2 release]; } I know, NSString* var is just a pointer to an allocated memory block, and 'assign' operation will increment this memory block's using count. For my situation, should I release m_movieName before assigning a value to it? If I do not release it (via [self.movieName release]), when and where will the previous block be released? Thanks for your help very much!

  • Is it possible to use 2 versions of jQuery on the same page?

    - by Ben McCormack
    NOTE: I know similar questions have already been asked here and here, but I'm looking for additional clarification as to how to make this work. I'm adding functionality to an existing web site that is already using an older version of the jQuery library (1.1.3.1). I've been writing my added functionality against the newest version of the jQuery library (1.4.2). I've tested the website using only the newer version of jQuery and it breaks functionality, so now I'm looking at using both versions on the same page. How is this possible? What do I need to do in my code to specify that I'm using one version of jQuery instead of another? For example, I'll put <script> tags for both versions of jQuery in the header of my page, but what do I need to do so that I know for sure in my calling code that I'm calling one version of the library or another? Maybe something like this: //Put some code here to specify a variable that will be using the newer //version of jquery: var $NEW = jQuery.theNewestVersion(); //Now when I use $NEW, I'll know it's the newest version and won't //conflict with the older version. $NEW('#personName').text('Ben'); //And when I use the original $ in code, or simply 'jquery', I'll know //it's the older version. $('#personName').doSomethingWithTheOlderVersion();
