  • Apache HttpClient 4.0. Weird behavior.

    - by Mikhail T
    Hello. I'm using Apache HttpClient 4.0 for my web crawler. The behavior i found strange is: i'm trying to get page via HTTP GET method and getting response about 404 HTTP error. But if i try to get that page using browser it's done successfully. Details: 1. I upload multipart form to server this way: HttpPost httpPost = new HttpPost("http://[host here]/in.php"); MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); entity.addPart("method", new StringBody("post")); entity.addPart("key", new StringBody("223fwe0923fjf23")); FileBody fileBody = new FileBody(new File("photo.jpg"), "image/jpeg"); entity.addPart("file", fileBody); httpPost.setEntity(entity); HttpResponse response = httpClient.execute(httpPost); HttpEntity result = response.getEntity(); String responseString = ""; if (result != null) { InputStream inputStream = result.getContent(); byte[] buffer = new byte[1024]; while(inputStream.read(buffer) > 0) responseString += new String(buffer); result.consumeContent(); } Uppload succefully ends. I'm getting some results from web server: HttpGet httpGet = new HttpGet("http://[host here]/res.php?key="+myKey+"&action=get&id="+id); HttpResponse response = httpClient.execute(httpGet); HttpEntity entity = response.getEntity(); I'm getting ClientProtocolException while execute method run. I was debugging this situation with log4j. Server answers "404 Not Found". But my browser loads me that page with no problem. Can anybody help me? Thank you.

  • How can I control the height of a ListView in WPF, using a complex DataTemplate with DataTriggers?

    - by Rob Perkins
    I have a ListView element with a DataTemplate for each ListViewItem defined as follows. When run, the ListView's height is not collapsed onto the items in the view, which is undesirable behavior: <DataTemplate x:Key="LicenseItemTemplate"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding company}"></TextBlock> <Grid Grid.Row="1" Style="{StaticResource HiddenWhenNotSelectedStyle}"> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <Button Grid.Row="0">ClickIt</Button> </Grid> </Grid> </DataTemplate> The second row of the outer grid has a style applied which looks like this. The purpose of the style is to : <Style TargetType="{x:Type Grid}" x:Key="HiddenWhenNotSelectedStyle" > <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem} } }" Value="True"> <Setter Property="Grid.Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> The ListView renders like this: The desired appearance is this, when none of the elements are selected: ...with, of course, the ListView's height adjusting to accommodate the additional content when the second grid is made visible by selection. What can I do to get the desired behavior?

  • jQuery update not replacing js files in Drupal 6.16.

    - by vr3690
    Hi, I am using jquery update in drupal 6.16 along with a lot of other modules. I am trying to use jquery ui 1.7.2 to render tabs. But unfortunately they don't work properly since jquery update is not replacing the jquery file (jquery 1.3.2). I checked the version using $.fn.jquery (in firebug) and got 1.2.6 (not 1.3.2 as required) as the result - and as expected the aggregated js file was using the 1.2.6 version of jquery (see source). earlier I had just replaced the core script files in /misc with the js files in sites/default/modules/jquery_update/replace folder (like you'd do in 5.x) and got the necessary result (i also renamed jquery.min.js to jquery.js ). now suddenly that stopped working after i upgraded to 6.x-2.0-alpha1 and also installed the mollom module. disabling/uninstalling mollom or down-grading jQuery update does not seem to help. the problem only occurs on the front page though. other content pages have jQuery 1.3.2 the problem can be seen here. So, basically, for some reason, jquery update is not replacing the jquery files (as it is supposed to) on the front page. and i cannot figure out why that happens. any ideas?

  • Querying datetime.datetime on appengine acts different then dev server help!

    Hey, I'm having some trouble with stuff that work locally and dont work on the app engine python environment: Basically, i want to get a program from an epg between ranges of date and time. i know i cannot do two where < so i saw a suggestion to save the dates as list as datetime.datetime which i did. [datetime.datetime(2010, 5, 10, 14, 25), datetime.datetime(2010, 5, 10, 15, 0)] This is ok. but when i try to compare to it: progranon = get_object(Programs2Channel, 'channel_id =', channelobj.key(), 'endstartdate >', programstart_minex, 'endstartdate <', programstart_minex ) This for some reason works locally, but fails to retrieve the data on the app engine. *Im using Google app engine django patch which uses the get_object to retrieve data in transactions.

  • How to have multiple instances of jQuery plugin on single page?

    - by James Skidmore
    I'm writing a simple jQuery plugin, but I'm having trouble being able to use multiple instances on a page. For instance, here is a sample plugin to illustrate my point: (function($) { $.fn.samplePlugin = function(options) { if (typeof foo != 'undefined') { alert('Already defined!'); } else { var foo = 'bar'; } }; })(jQuery); And then if I do this: $(document).ready(function(){ $('#myDiv').samplePlugin({}); // does nothing $('#myDiv2').samplePlugion({}); // alerts "Already defined!" }); This is obviously an over-simplified example to get across the point. So my question is, how do I have two separate instances of the plugin? I'd like to be able to use it across multiple instances on the same page. I'm guessing that part of the problem might be with defining the variables in a global scope. How can I define them unique to that instance of the plugin then? Thank you for your guidance!

  • Go - Using a map for its set properties with user defined types

    - by Seth Hoenig
    I'm trying to use the built-in map type as a set for a type of my own (Point, in this case). The problem is, when I assign a Point to the map, and then later create a new, but equal point and use it as a key, the map behaves as though that key is not in the map. Is this not possible to do? // maptest.go package main import "fmt" func main() { set := make(map[*Point]bool) printSet(set) set[NewPoint(0, 0)] = true printSet(set) set[NewPoint(0, 2)] = true printSet(set) _, ok := set[NewPoint(3, 3)] // not in map if !ok { fmt.Print("correct error code for non existent element\n") } else { fmt.Print("incorrect error code for non existent element\n") } c, ok := set[NewPoint(0, 2)] // another one just like it already in map if ok { fmt.Print("correct error code for existent element\n") // should get this } else { fmt.Print("incorrect error code for existent element\n") // get this } fmt.Printf("c: %t\n", c) } func printSet(stuff map[*Point]bool) { fmt.Print("Set:\n") for k, v := range stuff { fmt.Printf("%s: %t\n", k, v) } } type Point struct { row int col int } func NewPoint(r, c int) *Point { return &Point{r, c} } func (p *Point) String() string { return fmt.Sprintf("{%d, %d}", p.row, p.col) } func (p *Point) Eq(o *Point) bool { return p.row == o.row && p.col == o.col }

  • Joining Tables Based on Foreign Keys

    - by maestrojed
    I have a table that has a lot of fields that are foreign keys referencing a related table. I am writing a script in PHP that will do the db queries. When I query this table for its data I need to know the values associated with these keys not the key. How do most people go about this? A 101 way to do this would be to query this table for its data including the foreign keys and then query the related tables to get each key's value. This could be a lot of queries (~10). Question 1: I think I could write 1 query with a bunch of joins. Would that be better? This approach also requires the querying script to know which table fields are foreign keys. Since I have many tables like this but all with different fields, this means writing nice generic functions is hard. MySQL InnoDB tables allow for foreign constraints. I know the database has these set up correctly. Question 2: What about the idea of querying the table and identifying what the constraints are and then matching them up using whatever process I decide on from Question 1. I like this idea but never see it being used in code. Makes me think its not a good idea for some reason. I would use something like SHOW CREATE TABLE tbl_name; to find what constraints/relationships exist for that table. Thank you for any suggestions or advice.

  • How to make the value of one select box drive the options of a second select box

    - by Ben McCormack
    I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this dynamically on the client (using javascript or jQuery) rather than having to submit data to the server. For example, let's say I have the following Menu Categories and Menu Items: Sandwiches Turkey Ham Bacon Sides Mac 'n Cheese Mashed Potatoes Drinks Coca Cola Sprite Sweetwater 420 I would have two select boxes, named Menu Category and Items, respectively. When the user selects Sandwiches in the Menu Category box, the options in the Items box will only show Sandwich options. I'm stuck as how I might approach this. Once I filter out the 2nd list one time, how do I "find" the list options once I change my menu category in the 1st list? Also, if I'm thinking in SQL, I would have a key in the 1st box that would be used to link to the data in the 2nd box. However, I can't see where I have room for a "key" element in the 2nd box. How could this problem be solved with a combination of jQuery or plain javascript?

  • SQL query for selecting the firsts in a series by cloumn

    - by SP
    I'm having some trouble coming up with a query for what I am trying to do. I've got a table we'll call 'Movements' with the following columns: RecID(Key), Element(f-key), Time(datetime), Room(int) The table is holding a history of Movements for the Elements. One record contains the element the record is for, the time of the recorded location, and the room it was in at that time. What I would like are all records that indicate that an Element entered a room. That would mean the first (by time) entry for any element in a series of movements for that element in the same room. The input is a room number and a time. IE, I would like all of the records indicating that any Element entered room X after time Y. The closest I came was this Select Element, min(Time) from Movements where Time > Y and Room = x group by Element This will only give me one room entry record per Element though (If the Element has entered the room X twice since time Y I'll only get the first one back) Any ideas? Let me know if I have not explained this clearly. I'm using MS SQLServer 2005.

  • Delete element from Set

    - by Blitzkr1eg
    Hi. I have 2 classes Tema(Homework) and Disciplina (course), where a Course has a Set of homeworks. In Hibernate i have mapped this to a one-to-many associations like this: <class name="model.Disciplina" table="devgar_scoala.discipline" > <id name="id" > <generator class="increment"/> </id> <set name="listaTeme" table="devgar_scoala.teme"> <key column="Discipline_id" not-null="true" ></key> <one-to-many class="model.Tema" ></one-to-many> </set> </class> <class name="model.Tema" table="devgar_scoala.teme" > <id name="id"> <generator class="increment" /> </id> <property name="titlu" type="string" /> <property name="cerinta" type="binary"> <column name="cerinta" sql-type="blob" /> </property> </class> The problem is that it will add (insert rows in the table 'Teme') but it won't delete any rows and i get no exceptions thrown. Im using the merge() method.

  • autologin component doesn't work on remote server

    - by user606521
    I am using autologin component from http://milesj.me/code/cakephp/auto-login (v 3.5.1). It works on my localhost WAMP server but fails on remote server. I am using this settings in beforeFilter() callback: $this->AutoLogin->settings = array( // Model settings 'model' => 'User', 'username' => 'username', 'password' => 'password', // Controller settings 'plugin' => '', 'controller' => 'users', // Cookie settings 'cookieName' => 'rememberMe', 'expires' => '+1 month', // Process logic 'active' => true, 'redirect' => true, 'requirePrompt' => true ); On remote server it simply doesn't autolog users after the browser was closed. I can't figure out what may cause the problem. -------------------- edit I figured out what is causing the problem but I don't know how to fix this. First of all cookie is set like this: $this->Cookie->write('key',array('username' => 'someusername', 'hash' => 'somehash', ...) ); Then it's readed like this: $cookie = $this->Cookie->read('key'); On my WAMP server $cookie is array('username' => 'someusername', 'hash' => 'somehash', ...) and on remote server returned $cookie is string(159) "{\"username\":\"YWxlay5iYXJzsdsdZXdza2ldssd21haWwuY29t\",\"password\":\"YWxlazc3ODEy\",\"hash\":\"aa15bffff9ca12cdcgfgb351d8bfg2f370bf458\",\"time\":1339923926}" and it should be: array( 'username' => "YWxlay5iYXJzsdsdZXdza2ldssd21haWwuY29t", 'password' => "YWxlazc3ODEy", ...) Why the retuned cookie is string not array?

  • Global hotkey capture in VB.net

    - by ggonsalv
    I want to have my app which is minimized to capture data selected in another app's window when the hot key is pressed. My app definitely doesn't have the focus. Additionally when the hot key is pressed I want to present a fading popup (Outlook style) so my app never gets focus. At a minimum I want to capture the Window name, Process ID and the selected data. The app which has focus is not my application? I know one option is to sniff the Clipboard, but are there any other solutions. This is to audit the rate of data-entry in to another system of which I have no control. It is a mainframe emulation client program(attachmate). The plan is complete data entry in Application X. Select a certain section of the screen in App X which is proof of data entry (transaction ID). Press the Magic Hotkey, which then 'sends' the selection to my App. From System.environment or system.Threading I can find the Windows logon. Similiarly I can also capture the time. All the data will be logged to SQL. Once Complete show Outlook style pop up saying the data entry has been logged. Any thoughts.

  • mysql subquery strangely slow

    I have a query to select from another sub-query select. While the two queries look almost the same the second query (in this sample) runs much slower: SELECT user.id ,user.first_name -- user.* FROM user WHERE user.id IN (SELECT ref_id FROM education WHERE ref_type='user' AND education.institute_id='58' AND education.institute_type='1' ); This query takes 1.2s Explain on this query results: id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY user index first_name 152 141192 Using where; Using index 2 DEPENDENT SUBQUERY education index_subquery ref_type,ref_id,institute_id,institute_type,ref_type_2 ref_id 4 func 1 Using where The second query: SELECT -- user.id -- user.first_name user.* FROM user WHERE user.id IN (SELECT ref_id FROM education WHERE ref_type='user' AND education.institute_id='58' AND education.institute_type='1' ); Takes 45sec to run, with explain: id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY user ALL 141192 Using where 2 DEPENDENT SUBQUERY education index_subquery ref_type,ref_id,institute_id,institute_type,ref_type_2 ref_id 4 func 1 Using where Why is it slower if i query only by index fields?

  • ANT propertyfile entry is not resolving to its value

    - by Brian
    I have a value in a properties file that I want to increment while the build is running. The goal is to copy a set of files and append a number to the front of each in order to maintain the order in which they were copied into the directory. I am using the <propertyfile> task as follows: <propertyfile file="jsfiles.properties"> <entry key="file.number" type="int" operation="=" value="10" /> <entry key="file.number" type="int" default="010" operation="+" value="10" pattern="000" /> </propertyfile> Then I do the copy: <copy todir="${js-in.dir}"> <resources> ... </resources> <chainedmapper> <flattenmapper /> <globmapper from="*.js" to="${file.number}-*.js"/> </chainedmapper> </copy> This does exactly what I need it to EXCEPT that instead of the following output: 010-file1.js 020-file2.js 030-file3.js ... I get: ${file.number}-file1.js ${file.number}-file2.js ${file.number}-file3.js ... What am I doing wrong?

  • Multiple forms using Rails & jQuery & AJAX

    - by biggie8199
    I have multiple coupons on a page and I'm trying to get comments to work on each coupon. So for each coupon i have a comments form. Im using jQuery + Ajax to accomplish this. Here's what my code looks like. Coupon Page <p>Comments:</p> <% form_for(@comment) do |f| %> <%= f.label :body %><br /><%= f.text_field :body, :size => "24" %> <%= f.hidden_field :coupon_id, :value => coupon.id %> <%= f.submit "Save" %> <% end %> Application.js jQuery.ajaxSetup({ 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")} }) jQuery.fn.submitWithAjax = function() { this.submit(function() { $.post(this.action, $(this).serialize(), null, "script"); return false; }) return this; }; $(document).ready(function() { $("#new_comment").submitWithAjax(); }) I tried changing the jQuery selector to a class $(".new_comment").submitWithAjax(); Thinking that would work, now all the submit buttons work, however it posts only the first form on the page. What can I change to make it so ajax submits the correct form and not the first one?

  • jQuery issue with anchor tag using jqTransform

    I'm using jqtransform on my site. When the user is on a for them to be able to use hot keys to move through the selections. I added this function: $wrapper.find('a').keydown(function (e) { var Esc = 27; var code = (e.keyCode ? e.keyCode : e.which); if(code== Esc || (code>=65 &&code<=90)){ var letter = String.fromCharCode(code); if (code==Esc) keyCodes = ""; else{ if (keyCodes=='') keyCodes += letter; else keyCodes += letter.toLowerCase(); var item = $wrapper.find('a[text^=\'' + keyCodes + '\']:first'); item.click(); } } }); inside of $.fn.jqTransSelect. This code works fine in all browsers but IE. the only thing i can find is that IE doesn't like the click event. Can anyone please help me with this? If i debug into the code I can see that item is a select not an anchor like i would expect it to be, and that confuses me even more.

  • Highlighting correctly in an emacs major mode

    Hi, I am developing an emacs major mode for a language (aka mydsl). However, using the techniques on xahlee's site doesn't seem to be working for some reason (possibly older emacs dialect..)

  • Simple Database normalization question...

    - by user365531
    Hi all, I have a quick question regarding a database that I am designing and making sure it is normalized... I have a customer table, with a primary key of customerId. It has a StatusCode column that has a code which reflects the customers account status ie. 1 = Open, 2 = Closed, 3 = Suspended etc... Now I would like to have another field in the customer table that flags whether the account is allowed to be suspended or not... certain customers will be automatically suspended if they break there trading terms... others not... so the relevant table fields will be as so: Customers (CustomerId(PK):StatusCode:IsSuspensionAllowed) Now both fields are dependent on the primary key as you can not determine the status or whether suspensions are allowed on a particular customer unless you know the specific customer, except of course when the IsSuspensionAllowed field is set to YES, the the customer should never have a StatusCode of 3 (Suspended). It seems from the above table design it is possible for this to happen unless a check contraint is added to my table. I can't see how another table could be added to the relational design to enforce this though as it's only in the case where IsSuspensionAllowed is set to YES and StatusCode is set to 3 when the two have a dependence on each other. So after my long winded explanation my question is this: Is this a normalization problem and I'm not seeing a relational design that will enforce this... or is it actually just a business rule that should be enforced with a check contraint and the table is in fact still normalized. Cheers, Steve

  • How to handle images better in Android

    - by primal
    In the microblogging application I am developing I wish to show an user image beside each post in the timeline. The images are small in size(max 50*50 dip) and are not more than 10 in number. I've two approaches in my mind. 1) Allow user to chose an image from Gallery on signing up. Send the image to the server and on subsequent signups load the image from the server. I'm worried whether this approach is doing too much unnecessary work. 2) The same method is same as above in first step but this time the image is not send to the server but a key value associated with the image is sent to the server. On subsequent signups, after obtaining the key from the server the specific image is loaded from gallery. I am not sure whether the second approach is possible. Any corrections on this aspect would be much appreciated. Also, Is it possible to store an image in SharedPreferences? Any new approach to handle this problem better are welcome.

  • Is this a safe/valid hash method implementation?

    - by Sean
    I have a set of classes to represent some objects loaded from a database. There are a couple variations of these objects, so I have a common base class and two subclasses to represent the differences. One of the key fields they have in common is an id field. Unfortunately, the id of an object is not unique across all variations, but within a single variation. What I mean is, a single object of type A could have an id between, say, 0 and 1,000,000. An object of type B could have an id between, 25,000 and 1,025,000. This means there's some overlap of id numbers. The objects are just variations of the same kind of thing, though, so I want to think of them as such in my code. (They were assigned ids from different sets for legacy reasons.) So I have classes like this: @class BaseClass @class TypeAClass : BaseClass @class TypeBClass : BaseClass BaseClass has a method (NSNumber *)objectId. However instances of TypeA and TypeB could have overlapping ids as discussed above, so when it comes to equality and putting these into sets, I cannot just use the id alone to check it. The unique key of these instances is, essentially, (class + objectId). So I figured that I could do this by making the following hash function on the BaseClass: -(NSUInteger)hash { return (NSUInteger)[self class] ^ [self.objectId hash]; } I also implemented isEqual like so: - (BOOL)isEqual:(id)object { return (self == object) || ([object class] == [self class] && [self.objectId isEqual:[object objectId]]); } This seems to be working, but I guess I'm just asking here to make sure I'm not overlooking something - especially with the generation of the hash by using the class pointer in that way. Is this safe or is there a better way to do this?

  • 'LINQ query plan' horribly inefficient but 'Query Analyser query plan' is perfect for same SQL!

    - by Simon_Weaver
    I have a LINQ to SQL query that generates the following SQL : exec sp_executesql N'SELECT COUNT(*) AS [value] FROM [dbo].[SessionVisit] AS [t0] WHERE ([t0].[VisitedStore] = @p0) AND (NOT ([t0].[Bot] = 1)) AND ([t0].[SessionDate] > @p1)',N'@p0 int,@p1 datetime', @p0=1,@p1='2010-02-15 01:24:00' (This is the actual SQL taken from SQL Profiler on SQL Server 2008.) The query plan generated when I run this SQL from within Query Analyser is perfect. It uses an index containing VisitedStore, Bot, SessionDate. The query returns instantly. However when I run this from C# (with LINQ) a different query plan is used that is so inefficient it doesn't even return in 60 seconds. This query plan is trying to do a key lookup on the clustered primary key which contains a couple million rows. It has no chance of returning. What I just can't understand though is that the EXACT same SQL is being run - either from within LINQ or from within Query Analyser yet the query plan is different. I've ran the two queries many many times and they're now running in isolation from any other queries. The date is DateTime.Now.AddDays(-7), but I've even hardcoded that date to eliminate caching problems. Is there anything i can change in LINQ to SQL to affect the query plan or try to debug this further? I'm very very confused!

  • RSKeyMgmt -r unable to remove installtion ID

    - by Eves
    I have backed up databases on one 2005 SQL Server and have restored those databases on a second 2005 SQL Server. I am currently trying to remove the new server's OLD key instance ID using the Reporting Services Key Manager (RSKeyMgmt -r). Prior to running the removal command the list of the current instances shows the new server's OLD instance ID as well as the NEW instance ID from the first SQL Server. Executing the RSKeyMgmt -r command results in: "The command completed successfully". However, when I recheck the listing of current instance IDs I see both the OLD and NEW instance IDs. In addition, when I check the Application Event Viewer I see an error: Report Server Windows Service (MSSQLSERVER) has not been granted access to the catalog content Does anyone know why I would be getting the above application error? Or...does anyone know what I would need to do to give access to the catalog to the Report Server Window Service? The first SQL Server where the databases were backed up is an Enterprise edition SQL Server and the second SQL Server where the databases were restored is Standard edition. Could this be the cause of the problem? Is there a way to make this backup and restore migration work?

  • How to properly set relationships in Core Data when using setValue and data already exists

    - by ern
    Let's say I have two objects: Articles and Categories. For the sake of this example all relevant categories have already been added to the data store. When looping through data that holds edits for articles, there is category relationship information that needs to be saved. I was planning on using the -setValue method in the Article class in order to set the relationships like so: - (void)setValue:(id)value forUndefinedKey:(NSString *)key { if([key isEqualToString:@"categories"]){ NSLog(@"trying to set categories..."); } } The problem is that value isn't a Category, it is just a string (or array of strings) holding the title of a category. I could certainly do a lookup within this method for each category and assign it, but that seems inefficient when processing a whole bunch of articles at once. Another option is to populate an array of all possible categories and just filter, but my question is where to store that array? Should it be a class method on Article? Is there a way to pass in additional data to the -setValue method? Is there another, better option for setting the relationship I'm not thinking of? Thanks for your help.

  • Borderless ImageButtons in WrapPanel

    - by Bill
    I am attempting to create a WrapPanel with seamless ImageButtons containing Artwork. I put together the following ContentTemplate in the hopes that it would provide the seamless look required; however a thin white-line remained around each of the buttons. Can anyone steer me in the right direction? <Button.ContentTemplate> <DataTemplate DataType="{x:Type local:ArtInfo}"> <Border Name="border" BorderThickness="0" BorderBrush="blue" Height="280" Width="250" Background="#262c40"> <StackPanel> <Grid> <Grid.Resources> <local:MyConverter x:Key="MyConverter"></local:MyConverter> <ObjectDataProvider x:Key="Properties.Settings" ObjectType="{x:Type lcl:Properties.Settings}" /> </Grid.Resources> <Image Name="ArtImage" Margin="10,15,0,0" Height="195" Width="195" VerticalAlignment="Top" > <Image.Source> <Binding Path="ArtImage"/> </Image.Source> </Image> </Grid> <TextBlock Text="{Binding Path=ArtClass}" Margin="10,-17,0,0" FontSize="11" Foreground="white" /> <TextBlock Text="{Binding Path=Student}" Margin="10,0,0,0" FontSize="11" Foreground="white" /> <TextBlock Text="1998" Margin="10,0,0,0" FontSize="11" Foreground="white" /> </StackPanel> </Border> </DataTemplate> </Button.ContentTemplate>
