  • WPF, Setting property with single value on multiple subcontrols

    - by Andre van Heerwaarde
    I have a parent contentcontrol which displays data via a datatemplate. The datatemplate contains a stackpanel with several usercontols of the same type. I like to set the property only once on the parent control, it must set the value of the property on all the subcontrols. But if there is a way to do it on the stackpanel it's also OK. The template can be changed at runtime and the values need also to be propagated to the new template. My current solution is to implement the property on both parent and subcontrol and use code to propagate the value from the parent to all the subcontrols. My question is: is there a better or other ways of doing this?

  • xquery expression to return a link text only if it contains within it a specific string

    - by Arvind
    I want to extract some links from a XML document (links are in same format as on html pages). Now for eg a link is "http://xyz.com/start/tyu/a.html" and another is "http://ert.com/tyu/b.html" while a third link is "http://asdf.com/ghjk/c.html" From the above 3 links (which I have with me using a for clause in a FLWOR expression)...I want only the links which contain within them a string "tyu" to be selected-- I thought of using substring for this, but substring requires start and end positions to be specified- whereas in my scenario, I dont know at which position the desired string will be. How do I do substring matching in such a scenario, i.e. where exact position for occurrence of substring, is not known? I can use XQuery 1.0 for this purpose. Finally, I want to extract the link URL, as well as link text...

  • Silverlight: Use reflection to get the BindingExpression (and value) for controls having a ContentPr

    - by sfx
    Hello, I need to use reflection to get the binding value in a control that is a DataGridTemplateColumn (e.g HyperLinkButton). Does anyone know how I might do this? It seems simple enough to do this with a TextBlock because it has a “TextProperty” dependency property, but I can’t seem to get a binding expression from a control that does not have an immediate “TextProperty”. Here is the code I’m using to acquire the binding expression for a TextBlock: FrameworkElement fe = (FrameworkElement)dependencyObj; FieldInfo fi = fe.GetType().GetField("TextProperty"); BindingExpression bindingExpression = fe.GetBindingExpression((DependencyProperty)fi.GetValue(null)) However, the following code never works for a dependency object that is a HyperLinkButton: FieldInfo fi = fe.GetType().GetField("ContentProperty"); Does anyone know how I might be able to get the BindingExpression (and binding value) for the content of a HyperLinkButton? Cheers, sfx

  • HttpContext User value changing on its own?

    - by larryq
    Hi everyone, I'm working on an ASP.Net 2.0 application and am having a strange issue involving the HttpContext User. It appears to be changing on its own when I go to a particular page/directory. All of our pages inherit from a base page. In that base page's Page_Load() method we run an authorization check to see if the user can see the page they're going to. We retrieve the user to check against with this code: GenericPrincipal objPrincipal = (GenericPrincipal)Context.User; When I go to this unusual directory the User value isn't me, it's some other username I've never heard of. This username isn't authorized to see these pages, so authorization fails. This mysterious directory isn't a virtual web, just a regular directory in our website, however I've noticed it has its own Web.Config file. I'm guessing that's a cause of the trouble here. My question is, how can I investigate this further, in determining what's changing the User value when I go to this directory?

  • Return tiff file from outputstream on JSP

    - by YYY
    I am using a JSP to display a single TIFF file. The flow is as follows: I am given a PDF to convert to a TIFF. I feed a 'black box' API the PDF in the form of a File object and an OutputStream (I am currently using a ByteArrayOutputStream but that can change as needed. The 'black box' converts the PDF to a TIFF and saves the result to the OutputStream. I use out.println(outputstream) to spit out the TIFF. The problem is that I am getting a text stream instead of a displayed image. I have used the following head/meta tag: <head><title>PDF to TIFF tester</title> <META HTTP-EQUIV="Content-Script-Type" CONTENT="image/tiff"></head> <body> But that does not change the end result. Any help?

  • assign member based on string value

    - by Aperion
    I need start off with code because I am not sure what terminology to use. Lets say I have the following code: class Node { public: void Parse(rapidxml::xml_node<> *node) { for (rapidxml::xml_attribute<> *attr = node->first_attribute(); attr; attr = attr->next_attribute()) { std::stringstream converter; converter << attr->value(); if( !strcmp(attr->name(), "x") ) converter >> x; else if( !strcmp(attr->name(),"y") ) converter >> y; else if( !strcmp(attr->name(), "z") ) converter >> z; } } private: float x; float y; float z; }; What I can't stand is the repetition of if( !strcmp(attr-name(), "x") ) converter x; I feel that this is error prone and monotonous, but I cannot think of another way to map a string value to a member assignment. What are some other approaches one can take to avoid code such as this? The only other possible alternative I could think of was to use a hashmap, but that runs into problems with callbacks This is the best I could up with but it's not as flexible as I'd like: class Node { Node() : x(0.0f), y(0.0f), z(0.0f) { assignmentMap["x"] = &x; assignmentMap["y"] = &y; assignmentMap["z"] = &z; } public: void Parse(rapidxml::xml_node<> *node) { for (rapidxml::xml_attribute<> *attr = node->first_attribute(); attr; attr = attr->next_attribute()) { if( !attr->name() ) continue; std::stringstream converter; converter << attr->value(); converter >> *assignmentMap[attr->name()]; } } private: float x; float y; float z; std::map<std::string, float*> assignmentMap; };

  • Delphi TRttiType.GetMethods return zero TRttiMethod instances

    - by conciliator
    I've recently been able to fetch a TRttiType for an interface using TRttiContext.FindType using Robert Loves "GetType"-workaround ("registering" the interface by an explicit call to ctx.GetType, e.g. RType := ctx.GetType(TypeInfo(IMyPrettyLittleInterface));). One logical next step would be to iterate the methods of said interface. Consider program rtti_sb_1; {$APPTYPE CONSOLE} uses SysUtils, Rtti, mynamespace in 'mynamespace.pas'; var ctx: TRttiContext; RType: TRttiType; Method: TRttiMethod; begin ctx := TRttiContext.Create; RType := ctx.GetType(TypeInfo(IMyPrettyLittleInterface)); if RType <> nil then begin for Method in RType.GetMethods do WriteLn(Method.Name); end; ReadLn; end. This time, my mynamespace.pas looks like this: IMyPrettyLittleInterface = interface ['{6F89487E-5BB7-42FC-A760-38DA2329E0C5}'] procedure SomeProcedure; end; Unfortunately, RType.GetMethods returns a zero-length TArray-instance. Are there anyone able to reproduce my troubles? (Note that in my example I've explicitly fetched the TRttiType using TRttiContext.GetType, not the workaround; the introduction is included to warn readers that there might be some unresolved issues regarding rtti and interfaces.) Thanks!

  • Convert Null Value to String - C#.NET

    - by peace
    foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { PropertyItem.SetValue(this, objDataTable.Rows[0][PropertyItem.Name.ToString()], null); } In one of the loops i get this exceptional error: Object of type 'System.DBNull' cannot be converted to type 'System.String'. The error occurs because one of the fields in the database has no value (null), so the string property could not handle it. How can i convert this null to string? I got this solution If you know a shorter or better one, feel free to post it. I'm trying to avoid checking on every loop is current value is null or not.

  • Jquery - return html as a string

    - by McNabbToSkins
    I am using the Jquery Wysiwyg editor and I am trying to capture the html that makes up the content area to store in a DB. Is there anyway to get html of a element and save it as a string? My code looks like tihs <iframe id="wysiwyg_IFrame> <html> <head></head> <body> <ul> <li>This is a test</li> </ul> </body> </html> </iframe> I would either like to get a string that starts with <html>....</html> or just the body <body>...</body> does anyone know if this is possible? Thanks

  • How Pick a Column Value from a ListView Row - C#.NET

    - by peace
    How can i fetch the value 500 to a variable from the selected row? One solution would be to get the row position number and then the CustomerID position number. Can you please give a simple solution. SelectedItems means selected row and SubItems means the column values, so SelectedItem 0 and SubItem 0 would represent the value 500. Right? This is how i populate the listview: for (int i = 0; i < tempTable.Rows.Count; i++) { DataRow row = tempTable.Rows[i]; ListViewItem lvi = new ListViewItem(row["customerID"].ToString()); lvi.SubItems.Add(row["companyName"].ToString()); lvi.SubItems.Add(row["firstName"].ToString()); lvi.SubItems.Add(row["lastName"].ToString()); lstvRecordsCus.Items.Add(lvi); }

  • Conditionally set a column to its default value in Postgres

    - by Evgeny
    I've got a PostgreSQL 8.4 table with an auto-incrementing, but nullable, integer column. I want to update some column values and, if this column is NULL then set it to its default value (which would be an integer auto-generated from a sequence), but I want to return its value in either case. So I want something like this: UPDATE mytable SET incident_id = COALESCE(incident_id, DEFAULT), other = 'somethingelse' WHERE ... RETURNING incident_id Unfortunately, this doesn't work - it seems that DEFAULT is special and cannot be part of an expression. What's the best way to do this?

  • Large, high performance object or key/value store for HTTP serving on Linux

    - by Tommy
    I have a service that serves images to end users at a very high rate using plain HTTP. The images vary between 4 and 64kbytes, and there are 1.300.000.000 of them in total. The dataset is about 30TiB in size and changes (new objects, updates, deletes) make out less than 1% of the requests. The number of requests pr. second vary from 240 to 9000 and is dispersed pretty much all over, with few objects being especially "hot". As of now, these images are files on a ext3 filesystem distributed read only across a large amount of mid range servers. This poses several problems: Using a fileysystem is very inefficient since the metadata size is large, the inode/dentry cache is volatile on linux and some daemons tend to stat()/readdir() it's way through the directory structure, which in my case becomes very expensive. Updating the dataset is very time consuming and requires remounting between set A and B. The only reasonable handling is operating on the block device for backup, copying, etc. What I would like is a deamon that: speaks HTTP (get, put, delete and perhaps update) stores data it in an efficient structure. The index should remain in memory, and considering the amount of objects, the overhead must be small. The software should be able to handle massive connections with slow (if any) time needed to ramp up. Index should be read in memory at startup. Statistics would be nice, but not mandatory. I have experimented a bit with riak, redis, mongodb, kyoto and varnish with persistent storage, but I haven't had the chance to dig in really deep yet.

  • Why does PHP overwrite values when I iterate through this array twice (by reference, by value)

    - by jeremy
    If I iterate through an array twice, once by reference and then by value, PHP will overwrite the last value in the array if I use the same variable name for each loop. This is best illustrated through an example: $array = range(1,5); foreach($array as &$element) { $element *= 2; } print_r($array); foreach($array as $element) { } print_r($array); Output: Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 10 ) Array ( [0] = 2 [1] = 4 [2] = 6 [3] = 8 [4] = 8 ) Note that I am not looking for a fix, I am looking to understand why this is happening. Also note that it does not happen if the variable names in each loop are not each called $element, so I'm guessing it has to do with $element still being in scope and a reference after the end of the first loop.

  • strange segmentation fault during function return

    - by Kyle
    I am running a program on 2 different machines. On one it works fine without issue. On the other it results in a segmentation fault. Through debugging, I have figured out where the fault occurs, but I can't figure out a logical reason for it to happen.

  • Pass Value between MDI Child in WinForm using C#

    - by abhilashca
    I have an MDI Parent, containing a MenuStrip. When I click on one of the Menu, two Child Forms are displayed simultaneoulsy. I have a TextBox and a Send Button on one of my ChildForm. When I type-in something in that TextBox and Click the Send Button, I need to show that value in the TextBox of my Second Child Form. What I had done is, I wrote a Public Function in the Second Child Form and tried to invoke it by creating an object of Second Form, on the Send Button click event. When I put break points, in that Public Function, I find that the control is flowing through that Public function on cliking the Send button. But the passed value is not displayed. And, I know that is not the standard way to do that. Any sample script for help? Thanks.

  • Reset auto increment column value in script mysql

    Hi, I have two mysql tables, one needs to start its auto-increment column id with the last value of the last inserted row in the other table (plus 1). According to mysql manual you can restart the value of an auto increment column like this: mysql ALTER TABLE tbl AUTO_INCREMENT = 100; However, this is not possible: mysql ALTER TABLE tb2 AUTO_INCREMENT = (SELECT MAX(id) FROM tbl1); I need to perform something like this because I'm filling the tables using a script. Is there another way to achieve it?
