  • GUnload is null or undefined using Directions Service

    - by user1677756
    I'm getting an error using Google Maps API V3 that I don't understand. My initial map displays just fine, but when I try to get directions, I get the following two errors: Error: The value of the property 'GUnload' is null or undefined, not a Function object Error: Unable to get value of the property 'setDirections': object is null or undefined I'm not using GUnload anywhere, so I don't understand why I'm getting that error. As far as the second error is concerned, it's as if something is wrong with the Directions service. Here is my code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize(address) { directionsDisplay = new google.maps.DirectionsRenderer(); var geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.733963, -84.565501); var mapOptions = { center: latlng, zoom: 15, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); directionsDisplay.setMap(map); } function getDirections(start, end) { var request = { origin:start, destination:end, travelMode: google.maps.TravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } else { alert("Directions cannot be displayed for the following reason: " + status); } }); } I'm not very savvy with javascript, so I could have made some sort of error there. I appreciate any help I can get.

  • Cost of logic in a query

    - by FrustratedWithFormsDesigner
    I have a query that looks something like this: select xmlelement("rootNode", (case when XH.ID is not null then xmlelement("xhID", XH.ID) else xmlelement("xhID", xmlattributes('true' AS "xsi:nil"), XH.ID) end), (case when XH.SER_NUM is not null then xmlelement("serialNumber", XH.SER_NUM) else xmlelement("serialNumber", xmlattributes('true' AS "xsi:nil"), XH.SER_NUM) end), /*repeat this pattern for many more columns from the same table...*/ FROM XH WHERE XH.ID = 'SOMETHINGOROTHER' It's ugly and I don't like it, and it is also the slowest executing query (there are others of similar form, but much smaller and they aren't causing any major problems - yet). Maintenance is relatively easy as this is mostly a generated query, but my concern now is for performance. I am wondering how much of an overhead there is for all of these case expressions. To see if there was any difference, I wrote another version of this query as: select xmlelement("rootNode", xmlforest(XH.ID, XH.SER_NUM,... (I know that this query does not produce exactly the same, thing, my plan was to move the logic to PL/SQL or XSL) I tried to get execution plans for both versions, but they are the same. I'm guessing that the logic does not get factored into the execution plan. My gut tells me the second version should execute faster, but I'd like some way to prove that (other than writing a PL/SQL test function with timing statements before and after the query and running that code over and over again to get a test sample). Is it possible to get a good idea of how much the case-when will cost? Also, I could write the case-when using the decode function instead. Would that perform better (than case-statements)?

  • Need help/suggestions for creating fantasy sports scoring databases and queries

    - by MGumbel
    I'm trying to create a website for my friends and I to keep track of fantasy sports scoring. So far, I've been doing the calculations and storage in Excel, which is very tedious. I'm trying to make it more simplified and automated through a SQL database that I can then wrap a web app around to enter daily stat updates. It's premised on our participation in another commercial site where we trade virtual shares of athletes, and thus acquire an "ownership percentage" in each athlete. For instance, if there are 100 shares of AROD, and I own 10 shares, then I own 10%. It then applies this to traditional baseball rotisserie scoring. So, for instance, if AROD has 1 HR today, then his adjusted HR stat would be 1.10. If he also has 2 RBI's, then his adjusted RBI stat today would be 2.20, based on (2 x 1.10)(1 to normalize the stat, and the .10 to represent the ownership percentage). All the stats for my team would then be summed each day and added to my stat history to come to an aggregated total. After that, points are allocated based on the ranking of each participant in each category at the end of the day. E.g. if there are 10 participants, and I have the highest total aggregate number of Adjusted HR's, then I get 10 pts. The points are then summed across the different stat categories to come up with a total point ranking for that day. An added difficulty is that ownership %'s can change on a daily basis. So far, in playing around with different schema, I don't know that having a separate table for each athlete's stats and each player's ownership %'s is the wisest choice. It seems to me that simply having two tables, one that contains the daily stat information for each athlete, and another that shows the ownership % of each player. My friend suggested using a start and end date for each ownership % to represent the potential daily changes in this category. I'm admittedly new to database development, so any suggestions on query code would be appreciated.

  • Why would using a Temp table be faster than a nested query?

    - by Mongus Pong
    We are trying to optimise some of our queries. One query is doing the following: SELECT t.TaskID, t.Name as Task, '' as Tracker, t.ClientID, (<complex subquery>) Date, INTO [#Gadget] FROM task t SELECT TOP 500 TaskID, Task, Tracker, ClientID, dbo.GetClientDisplayName(ClientID) as Client FROM [#Gadget] order by CASE WHEN Date IS NULL THEN 1 ELSE 0 END , Date ASC DROP TABLE [#Gadget] (I have removed the complex subquery, cos I dont think its relevant other than to explain why this query has been done as a two stage process.) Now I would have thought it would be far more efficient to merge this down into a single query using subqueries as : SELECT TOP 500 TaskID, Task, Tracker, ClientID, dbo.GetClientDisplayName(ClientID) FROM ( SELECT t.TaskID, t.Name as Task, '' as Tracker, t.ClientID, (<complex subquery>) Date, FROM task t ) as sub order by CASE WHEN Date IS NULL THEN 1 ELSE 0 END , Date ASC This would give the optimiser better information to work out what was going on and avoid any temporary tables. It should be faster. But it turns out it is a lot slower. 8 seconds vs under 5 seconds. I cant work out why this would be the case as all my knowledge of databases imply that subqueries would always be faster than using temporary tables. Can anyone explain what could be going on!?!?

  • Weird code appearing when I loop over model instances in Rails

    - by Tom Maxwell
    In my Rails app I'm trying to loop over the Submission instances inside my Folder instances with Rails templating code. It works. However, it's also returning each instance in code which doesn't seem to be JSON. It's what's returned when you look up an instance in the Rails console. Here's an example: #<Submission id: 112, title: nil, content: nil, created_at: "2013-10-10 23:29:39", updated_at: "2013-10-10 23:29:39", user_id: 1, folder_id: 1, parent_id: nil> Here's what the code looks like for the loop: <%= @folder.submissions.each do |x| %> <% if x.title != nil %> <div id="<%= x.id %>" class="submission-textual"> <h1><%= x.title %></h1> </div> <% else %> <% end %> <% end %> I checked my Folder and Submissions controllers but am not sure what this is. Why are these strings being rendered whenever I try and render an instance in my view? I'm still new to Ruby so that explains why I haven't seen this.

  • Dynamic use of :default_url in Paperclip

    - by dgilperez
    I'm trying to configure Paperclip to provide different missing images based on the instance's category attribute. Every category of the object has its own missing image. This is my first take: EDIT to add full models: class Service < ActiveRecord::Base attr_accessible :logo, :logo_file_name, :logo_content_type, :logo_file_size, :logo_updated_at belongs_to :category, :counter_cache => true has_attached_file :logo, :path => "/:id-:style-:filename", :url => ":s3_eu_url", :default_url => "/logos/:style/#{self.category.name]}.png", :styles => { :large => "600x400>", :medium => "300x200>", :small => "100x75>", :thumb => "60x42>" } end class Category < ActiveRecord::Base attr_accessible nil has_many :services end In my view, image_tag service.logo.url(:thumb) outputs: undefined method `category' for #<Class:0x0000010a731620> Any ideas? EDIT2: A working default_url is :default_url => "/logos/:style/missing.png", SOLUTION: See my own answer below.

  • Response as mail attachment

    using (MemoryStream stream = new MemoryStream()) { compositeLink.PrintingSystem.ExportToPdf(stream); Response.Clear(); Response.Buffer = false; Response.AppendHeader("Content-Type", "application/pdf"); Response.AppendHeader("Content-Transfer-Encoding", "binary"); Response.AppendHeader("Content-Disposition", "attachment; filename=test.pdf"); Response.BinaryWrite(stream.GetBuffer()); Response.End(); } I got this working fine.

  • Resources for setting up a Visual Studio/C++ development environment

    - by Tom H.
    I haven't done much "front-end" development in about 15 years since moving to database development. I'm planning to start work on a personal project using C++ and since I already have MSDN I'll probably end up doing it in Visual Studio 2010. I'm thinking about using Subversion as a version control system eventually. Of course, I'd like to get up and running as quickly as I can, but I'd also like to avoid any pitfalls from a poorly organized project environment. So, my question is, are there any good resources with common best practices for setting up a development environment? I'm thinking along the lines of where to break down a solution into multiple projects if necessary, how to set up a unit testing process, organizing resources, directories, etc. Are there any great add-ons that I should make sure I have set up from the start? Most tutorials just have one simple project, type in your code and click on build to see that your new application says, "Hello World!". This will be a Windows application with several DLLs as well (no web development), so there doesn't need to be a deploy to a web server kind of process. Mostly I just want to make sure that I don't miss anything big and then have to extensively refactor because of it. Thanks!

  • Why does Eclipse skip lines when I debug JBoss?

    - by ZeKoU
    Hi, I am trying to debug web service call which uses JMS in the background.I have JBoss running in debug mode. What happens is that when I press F6 in Eclipse (to execute current line) it skips certain lines. I have this method: @Override public void log(MsgPayload payload) { 1 Date startTime = new Date(); logger.info("Publishing with BufferedPublisher.java start time:"+startTime); 3 publisher.send(payload); Date endTime = new Date(); logger.info("Publishing with BufferedPublisher.java end time:"+endTime); long mills = endTime.getTime()-endTime.getTime(); double secs = mills/1000.0; logger.info("Publishing with BufferedPublisher.java total time (seconds):"+secs); } So what happens? I have breakpoint at line 1. When I press F6 it skips that line and goes to line 3. When I press F6 again it goes to the end of the method. Half of the code is never executed..??? My question is why. I am assuming my source is not well attached to the real code that is being executed.But how do I change this? Thanks.

  • Combining JavaScript for Google Analytics with yours. (Asynchronous tracking.)

    - by lorenzo 72
    I have a JavaScript file which is loaded up at the end of my HTML page. Rather than adding the script code for asynchronous tracking for Google in yet another script I would rather combine the two scripts together. So instead of this: <html> ... <script src="myScript.js"> <!-- google analytics --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga); })(); </script> </html> I would have that bit of code in the second script tag at the end of my 'myScript.js'. I have not found one place in google documentation where it suggests to combine the script with yours.

  • How to sort array with undefined elements in IE7 JavaScript

    - by Gene Goykhman
    I am having trouble sorting an array that includes undefined elements (a sparse array) in IE7. This works great in Safari and Firefox of course, and I haven't tried other versions of IE, but here is a simple example. <html> <head> <script type="text/javascript"> function runscript() { var myArray = [{id: 2}, undefined, {id: 0}, {id: 1}, {id: 3}, {id: 4}, {id: 5}]; myArray.sort(function compare(a, b) { return a.id - b.id; }); var output = ''; for (loop in myArray) { output += myArray[loop].id + ' '; } alert(output); } </script> </head> <body onLoad="runscript();"> </body> The alert() at the end inexplicably shows 0 2 3 4 5 1. Removing the undefined element from the array correctly sorts it and the alert shows 0 1 2 3 4 5. Is there a way to work around this in IE7 so that I can reliably sort arrays that include undefined elements? I don't care where the undefined elements end up as long as the defined elements are sorted correctly.

  • How to use a TFileStream to read 2D matrices into dynamic array?

    - by Robert Frank
    I need to read a large (2000x2000) matrix of binary data from a file into a dynamic array with Delphi 2010. I don't know the dimensions until run-time. I've never read raw data like this, and don't know IEEE so I'm posting this to see if I'm on track. I plan to use a TFileStream to read one row at a time. I need to be able to read as many of these formats as possible: 16-bit two's complement binary integer 32-bit two's complement binary integer 64-bit two's complement binary integer IEEE single precision floating-point For 32-bit two's complement, I'm thinking something like the code below. Changing to Int64 and Int16 should be straight forward. How can I read the IEEE? Am I on the right track? Any suggestions on this code, or how to elegantly extend it for all 4 data types above? Since my post-processing will be the same after reading this data, I guess I'll have to copy the matrix into a common format when done. I have no problem just having four procedures (one for each data type) like the one below, but perhaps there's an elegant way to use RTTI or buffers and then move()'s so that the same code works for all 4 datatypes? Thanks! type TRowData = array of Int32; procedure ReadMatrix; var Matrix: array of TRowData; NumberOfRows: Cardinal; NumberOfCols: Cardinal; CurRow: Integer; begin NumberOfRows := 20; // not known until run time NumberOfCols := 100; // not known until run time SetLength(Matrix, NumberOfRows); for CurRow := 0 to NumberOfRows do begin SetLength(Matrix[CurRow], NumberOfCols); FileStream.ReadBuffer(Matrix[CurRow], NumberOfCols * SizeOf(Int32)) ); end; end;

  • std::map keys in C++

    - by Soumava
    I have a requirement to create two different maps in C++. The Key is of type CHAR * and the Value is a pointer to a struct. I am filling 2 maps with these pairs, in separate iterations. After creating both maps I need find all such instances in which the value of the string referenced by the CHAR * are same. For this i am using the following code : typedef struct _STRUCTTYPE { .. } STRUCTTYPE, *PSTRUCTTYPE; typedef pair {CHAR *,PSTRUCTTYPE} kvpair; .. CHAR *xyz; PSTRUCTTYPE abc; after filling the information; Map.insert (kvpair(xyz,abc)); the above is repeated x times for the first map, and y times for the second map. after both are filled out; std::map {CHAR *, PSTRUCTTYPE} :: iterator Iter,findIter; for (Iter=iteratedMap-begin();Iter!=iteratedMap-end();mapIterator++) { char *key = Iter-first; printf("%s\n",key); findIter=otherMap-find(key); //printf("%u",findIter-second); if (findIter!=otherMap-end()) { printf("Match!\n"); } } The above code does not show any match, although the list of keys in both maps show obvious matches. My understanding is that the equals operator for CHAR * just equates the memory address of the pointers. My question is, what should i do to alter the equals operator for this type of key or could I use a different datatype for the string? *note : {} has been used instead of angle brackets as the content inside angle brackets was not showing up in the post.

  • Is there unresizable space in latex? Pictures in good looking grid.

    - by drasto
    I've created latex macro to typeset guitar chords diagrams(using picture environment). Now I want to make diagrams of different appear in good looking grid when typeset one next to each other as the picture shows: The picture. (on the picture: Labeled "First" bad layout of diagrams, labeled "Second" correct layout when equal number of diagrams in line) I'm using \hspace to make some skips between diagrams, otherwise they would be too near to each other. As you can see in second case when latex arrange pictures in so that there is same number of them in each line it works. However if there is less pictures in the last line they become "shifted" to the right. I don't want this. I guess is because latex makes the space between diagrams in first line a little longer for the line to exactly fit the page width. How do I tell latex not to resize spaces created by \hspace ? Or is there any other way ? I guess I cannot use tables because I don't know how many diagrams will fit in one line... This is current state of code: \newcommand{\spaceForChord}{1.7cm} \newcommnad{\chordChart}[1]{% %calculate dimensions xdim and ydim according to setings \begin{picture}(xdim, ydim){% %draw the diagram inside defined area }% \hspace*{\spaceForChord}% \hspace*{-\xdim}% }% %end preambule and begin document \begin{document} First:\\* \\* \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} %...above line is repeated 12 more times to produce result shown at the picture \end{document} Thanks for any help.

  • Security of Flex for payment website

    - by Mario
    So, it's been about 3 years since I wrote and went live with my company's main internet facing website. Originally written in php, I've since just been making minor changes here and there to progress the site as we've needed to. I've wanted to rewrite it from the ground up in the last year or so and now, we want to add some major features so this is a perfect time. The website in question is as close to a banking website as you'd get (without being a bank; sorry for the obscurity, but the less info I can give out, the better). For the rewrite, I want to separate the presentation layer from the processing layer as much as I can. I want the end user to be stuck in a box and not be able to get out so to speak (this is all because of PCI complacency, being PEN tested every 3 months, etc...) So, being probed every 3 months has increasingly made me nervous. We haven't failed yet and there hasen't been a breach yet, but I want to make sure I continue to pass (as much as I can anyways) So, I'm considering rewriting the presentation layer in Adobe Flex and do all the processing in PHP (effectively IMO, separating presentation from processing) - I would do all my normal form validation in flex (as opposed to javascript or php) and do my reads and writes to the db via php. My questions are: I know Flash has something like 99% market penetration - do people find this to be true? Has anyone seen on their own sites being in flash that someone couldn't access it? Flash in general has come under alot of attacks about security and the like - i know this. I would use a swf encryptor - disable debugging (which i got snagged on once on a different application), continue to use https and any other means i can think of. At the end of the day, everyone knows if someone wants in to the data bad enough, their going to find a ways in; i just wanna make it as difficult for them as i can. Any thoughts are appreciated. -Mario

  • Core Data object into an NSDictionary with possible nil objects

    - by Chuck
    I have a core data object that has a bunch of optional values. I'm pushing a table view controller and passing it a reference to the object so I can display its contents in a table view. Because I want the table view displayed a specific way, I am storing the values from the core data object into an array of dictionaries then using the array to populate the table view. This works great, and I got editing and saving working properly. (i'm not using a fetched results controller because I don't have anything to sort on) The issue with my current code is that if one of the items in the object is missing, then I end up trying to put nil into the dictionary, which won't work. I'm looking for a clean way to handle this, I could do the following, but I can't help but feeling like there's a better way. *passedEntry is the core data object handed to the view controller when it is pushed, lets say it contains firstName, lastName, and age, all optional. if ([passedEntry firstName] != nil) { [dictionary setObject:[passedEntry firstName] forKey:@"firstName"] } else { [dictionary setObject:@"" forKey:@"firstName"] } And so on. This works, but it feels kludgy, especially if I end up adding more items to the core data object down the road.

  • Chache problem running two consecutive HTTP GET requests from an APP1 to an APP2

    - by user502052
    I use Ruby on Rails 3 and I have 2 applications (APP1 and APP2) working on two subdomains: app1.domain.local app2.domain.local and I am tryng to run two consecutive HTTP GET requests from APP1 to APP2 like this: Code in APP1 (request): response1 = Net::HTTP.get( URI.parse("http://app2.domain.local?test=first&id=1") ) response2 = Net::HTTP.get( URI.parse("http://app2.domain.local/test=second&id=1") ) Code in APP2 (response): respond_to do |format| if <model_name>.find(params[:id]).<field_name> == "first" <model_name>.find(params[:id]).update_attribute ( <field_name>, <field_value> ) format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } elsif <model_name>.find(params[:id]).<field_name> == "second" format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } end end After the first request I get the correct XML (response1 is what I expect), but on the second it isn't (response2 isn't what I expect). Doing some tests I found that the second time that <model_name>.find(params[:id]).<field_name> run (for the elsif statements) it returns always a blank value so that the code in the elseif statement is never run. Is it possible that the problem is related on caching <model_name>.find(params[:id]).<field_name>? P.S.: I read about eTag and Conditional GET, but I am not sure that I must use that approach. I would like to keep all simple.

  • Writing a printList method for a Scheme interpreter in C

    - by Rehan Rasool
    I am new to C and working on making an interpreter for Scheme. I am trying to get a suitable printList method to traverse through the structure. The program takes in an input like: (a (b c)) and internally represent it as: [""][ ][ ]--> [""][ ][/] | | ["A"][/][/] [""][ ][ ]--> [""][ ][/] | | ["B"][/][/] ["C"][/][/] Right now, I just want the program to take in the input, make the appropriate cell structure internally and print out the cell structure, thereby getting (a (b c)) at the end. Here is my struct: typedef struct conscell *List; struct conscell { char symbol; struct conscell *first; struct conscell *rest; }; void printList(char token[20]){ List current = S_Expression(token, 0); printf("("); printf("First Value? %c \n", current->first->symbol); printf("Second value? %c \n", current->rest->first->first->symbol); printf("Third value? %c \n", current->rest->first->rest->first->symbol); printf(")"); } In the main method, I get the first token and call: printList(token); I tested the values again for the sublists and I think it is working. However, I will need a method to traverse through the whole structure. Please look at my printList code again. The print calls are what I have to type, to manually get the (a (b c)) list values. So I get this output: First value? a First value? b First value? c It is what I want, but I want a method to do it using a loop, no matter how complex the structure is, also adding brackets where appropriate, so in the end, I should get: (a (b c)) which is the same as the input. Can anyone please help me with this?

  • Added CAGradientLayer, getting this in my UIView dealloc: [CALayer release]: message sent to deallocated instance

    - by developerdoug
    Here there, I have a custom UIView. This view acts as a activity indicator but as label above the UIActivityIndicatorView. In the init, I add a CAGradientLayer. I allocate and initialize it and insert it at index 0 as a sublayer of the UIView layer property. In my dealloc method was called, I received a message in the console: - [CALayer release]: message sent to deallocated instance. My code: @interface LabelActivityIndicatorView () { UILabel *_label; UIActivityIndicatorView *_activityIndicatorView; CAGradientLayer *_gradientLayer; } @end @implementation LabelActivityIndicatorView //dealloc - (void) dealloc { [_label release]; [_activityIndicatorView release]; //even tried to remove the layer [_gradientLayer removeFromSuperLayer]; [_gradientLayer release]; [super dealloc]; } // init - (id) initWithFrame:(CGRect)frame { if ( (self = [super initWithFrame:frame]) ) { // init the label // init the gradient layer _gradientLayer = [[CAGradientLayer alloc] init]; [_gradientLayer setBounds:[self bounds]]; [_gradientLayer setPosition:CGPointMake(frame.size.width/2, frame.size.height/2)]; [[self layer] insertSublayer:_gradientLayer atIndex:0]; [[self layer] setNeedsDisplay]; } return self; } @end Anyone have any ideas. Since I'm allocating and initializing the gradient layer I'm responsible for releasing it. I should be able to alloc and init and assign to some ivar. Perhaps I should create a property with retain on it. Thanks,

    When I try and connect it my mysql database with JDBC in java, it doesn't go to my web server. Here is the code String dbtime; String dbUrl = "jdbc:mysql://184.172.176.18:3306/dcsoft_dcsoft_balloon"; String dbUser = "myuser"; String dcPass = "mypass"; String dbClass = "com.mysql.jdbc.Driver"; String query = "Select * FROM users"; try { Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection(dbUrl, dbUser, dcPass); Statement stmt = con.createStatement(); ResultSet rs = stmt.executeQuery(query); while (rs.next()) { dbtime = rs.getString(1); System.out.println(dbtime); } //end while con.close(); } //end try catch(ClassNotFoundException e) { e.printStackTrace(); } catch(SQLException e) { e.printStackTrace(); } This code is supposed to go to my web server but it gives this error java.sql.SQLException: Access denied for user 'dcsoft_dcsoft_java'@'jamesposse.force9.co.uk' (using password: YES) jamesposse.force9.co.uk is the not the address im trying to connect to I'm trying to connect to 184.172.176.18:3306.

  • VB.NET Update Access Database with DataTable

    - by sinDizzy
    I've been perusing some hep forums and some help books but cant seem to get my head wrapped around this. My task is to read data from two text files and then load that data into an existing MS Access 2007 database. So here is what i'm trying to do: Read data from first text file and for every line of data add data to a DataTable using CarID as my unique field. Read data from second text file and look for existing CarID in DataTable if exists update that row. If it doesnt exist add a new row. once im done push the contents of the DataTable to the database. What i have so far: Dim sSQL As String = "SELECT * FROM tblCars" Dim da As New OleDb.OleDbDataAdapter(sSQL, conn) Dim ds As New DataSet da.Fill(ds, "CarData") Dim cb As New OleDb.OleDbCommandBuilder(da) 'loop read a line of text and parse it out. gets dd, dc, and carId 'create a new empty row Dim dsNewRow As DataRow = ds.Tables("CarData").NewRow() 'update the new row with fresh data dsNewRow.Item("DriveDate") = dd dsNewRow.Item("DCode") = dc dsNewRow.Item("CarNum") = carID 'about 15 more fields 'add the filled row to the DataSet table ds.Tables("CarData").Rows.Add(dsNewRow) 'end loop 'update the database with the new rows da.Update(ds, "CarData") Questions: In constructing my table i use "SELECT * FROM tblCars" but what if that table has millions of records already. Is that not a waste of resources? Should i be trying something different if i want to update with new records? Once Im done with the first text file i then go to my next text file. Whats the best approach here: To First look for an existing record based on CarNum or to create a second table and then merge the two at the end? Finally when the DataTable is done being populated and im pushing it to the database i want to make sure that if records already exist with three primary fields (DriveDate, DCode, and CarNum) that they get updated with new fields and if it doesn't exist then those records get appended. Is that possible with my process? tia AGP

  • Python 2.6 does not like appending to existing archives in zip files

    - by user313661
    Hello, In some Python unit tests of a program I'm working on we use in-memory zipfiles for end to end tests. In SetUp() we create a simple zip file, but in some tests we want to overwrite some archives. For this we do "zip.writestr(archive_name, zip.read(archive_name) + new_content)". Something like import zipfile from StringIO import StringIO def Foo(): zfile = StringIO() zip = zipfile.ZipFile(zfile, 'a') zip.writestr( "foo", "foo content") zip.writestr( "bar", "bar content") zip.writestr( "foo", zip.read("foo") + "some more foo content") print zip.read("bar") Foo() The problem is that this works fine in Python 2.4 and 2.5, but not 2.6. In Python 2.6 this fails on the print line with "BadZipfile: File name in directory "bar" and header "foo" differ." It seems that it is reading the correct file bar, but that it thinks it should be reading foo instead. I'm at a loss. What am I doing wrong? Is this not supported? I tried searching the web but could find no mention of similar problems. I read the zipfile documentation, but could not find anything (that I thought was) relevant, especially since I'm calling read() with the filename string. Any ideas? Thank you in advance!
