  • asp.net C# variable as Image1.ImageUrl property

    - by ModS
    I would like to Click "buttonImage1" and have that store "photos/Image1.jpg" into a var called Photo. then have ButtonImage2.ImageUrl = (Photo). I am using an UpdatePanel to refresh the area with the images so the only problem is actually setting the variable correctly and then using it correctly. Reworded: how can I store a path to an image in a variable then set it correctly as a image's URL path? protected void Button2_Click(object sender, ImageClickEventArgs e) { Evt = ("~/events/ev2.jpg"); } protected void Image2_Click(object sender, ImageClickEventArgs e) { Image1.ImageUrl = (Evt); }

  • Map a property in the entity framework to a different type

    - by Tom
    I have a SQL Server 2008 database. I have a bunch of fields in TableA that are just strings that corresponds to booleans. So every value is either true or false. The edmx I generated using Entity Framework 4.0 has them as strings. This is technically correct but I would like to have them mapped as Booleans instead. Is this possible? If so how can I accomplish this? Thanks much!

I know that you can do Distinct().OrderBy but how do i get a reference to the interactions table that was joined when I'm only selecting the opportunity entity?

  • Visual Studio Property Page Inherit Macros From Other Projects

    So I am having a very difficult time finding a solution to this problem. Is there any way that I can inherit macros from another project. For example, for the post build I would like to use the macro for the RemoteMachine address that is located in one project in all the other projects. I was thinking something like (ProjectContainingMacro.$RemoteMachine) ... does anyone have any suggestions?

  • return only one document for each filter defined in the query

    - by Garytxo
    Hi all, In one of my latest projects I use Solr 1.4 for searching products.However I have ran into a slight problem, which I aint sure if its possible to do using Solr. All products are indexed by "country" and "category" and the "id", "class" and "description" are stored values. I now have been requested to extract a sample list of products that we have for a give "category" and "ONLY RETURNING ONE" product for each country where the product is available. In my current implementation, I have a dismax query to get a list of all the countries that correspond to the catergory, then I call again solr to extract all products for each country, limiting the no. rows by the size of the countries found in the previous query. The problem I have with this current implementation is I can not be certain that I have one product for each country in the list. Therefore would anyone know if it possible to tell solr that you want only one product per country provided in the query? Any guidance would be useful.

  • Grouping by property value and writing group members

    - by Will S
    I need to group the following list by the department value but am having trouble with the LINQ syntax. Here's my list of objects: var people = new List<Person> { new Person { name = "John", department = new List<fields> {new fields { name = "department", value = "IT"}}}, new Person { name = "Sally", department = new List<fields> {new fields { name = "department", value = "IT"}}}, new Person { name = "Bob", department = new List<fields> {new fields { name = "department", value = "Finance"}}}, new Person { name = "Wanda", department = new List<fields> {new fields { name = "department", value = "Finance"}}}, }; I've toyed around with grouping. This is as far as I've got: var query = from p in people from field in p.department where field.name == "department" group p by field.value into departments select new { Department = departments.Key, Name = departments }; So can iterate over the groups, but not sure how to list the Person names - foreach (var department in query) { Console.WriteLine("Department: {0}", department.Department); foreach (var foo in department.Department) { // ?? } } Any ideas on what to do better or how to list the names of the relevant departments?

  • Is read-only auto-imlemented property possible?

    - by abatishchev
    Hello. I found a topic on MSDN that talks that yes, this is possible. I did a test that seems to break this statement: using System; namespace Test { class Program { static void Main(string[] args) { Foo f = new Foo("1"); Console.WriteLine(f.Bar); // prints 1 f.Test("2"); Console.WriteLine(f.Bar);// successfully prints 2 } } class Foo { public Foo(string b) { this.Bar = b; } public string Bar { get; private set; } public void Test(string b) { // this would be impossible for readonly field! // next error would be occur: CS0191 or CS0191 // A readonly field cannot be assigned to (except in a constructor or a variable initializer) this.Bar = b; } } } Where am I wrong?

  • How can I provide property-level string formatting?

    - by jhubsharp
    Not sure if the question wording is accurate, but here's what I want to do: I want to databind a class with some strings in it: class MyClass { public string MyProperty { get; set; } public string MyProperty2 { get; set; } } When databinding, everything behaves normally. On the back end, I'm writing to a file and I want MyProperty2 to always be encrypted using some encryption algorithm. I want my back-end code to write each string without needing to know that encryption is required (I want the class to know it should be encrypted, not the consumer). Can I do this with a type converter, or something similar? EDIT: There are other scenarios as well. Some booleans I want to format as "Y" or "N", other booleans I want formatted as "Enabled" / "Disabled", etc. I can write (and have written) helper methods and let the file writer call the helper methods as appropriate, I'm just wondering if there's a way to do this without the file writer needing to know which objects need which kind of formatting and let the objects tell that to the file writer.

  • Calculate sum of objects for each unique object property in Ruby

    - by macek
    I was helping with an answer in this question and it sparked a question of my own. Pie is an object that has a pieces array made of of PiePiece objects. Each PiePiece has a flavor attribute How do I create a hash that looks like this: # flavor => number of pieces { :cherry => 3 :apple => 1 :strawberry => 2 } This works, but I think it could be improved def inventory hash = {} pieces.each do |p| hash[p.flavor] ||= 0 hash[p.flavor] += 1 end hash end Any ideas?

  • How can I embed a XML document inside a XHTML document?

    - by Oriol
    For example, how can I embed <?xml version="1.0" encoding="utf-8"?> <root> <node><![CDATA[Text]]></node> </root> in my XHTML? I know I can put it in a CDATA section... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <title>My title</title> </head> <body> <p>I am a XHTML paragraph!</p> <div> <![CDATA[ <?xml version="1.0" encoding="utf-8"?> <root> <node>Text</node> </root> ]]> </div> </body> </html> ... but then I have to remove XML file's CDATA sections and the XML is parsed as text instead of XML. Then, I get this... ... but I want something like this:

  • document.getElementByIdContains?

    - by johnshaddad
    Hello Is there, by any chance, a way to solve this problem: I have elements that have IDs such as "x_y_z". The unique part is "x_y", thus there is no two items that have the same combination of x and y.. However, using getElementById won't work because when I do it I only have the "x" and "y" part and not the Z (think of Z as a random incremental counter). Is there a way around this? So that when I have the "x" and "y" I say something like getElementByIdContains("x_y")? Thanks!

Any idea how to insert node without using insert or using insert effectively with treeviewsorter??

  • Provide an OnChange event for an internal property which is controlled externally?

    - by NGLN
    For fun and by request I am updating this ImageGrid component, a kind of listbox for images that has a FileNames property of type TStrings. For ease of writing, I have been misusing its FileNames.Objects property for bitmap storage. But since the TStrings type suggests that users of the component could or would want to use the Objects property for custom data, e.g. like TListBox.Items, I am rewriting the component to store the bitmaps elsewhere and leave FileNames.Objects untouched for unknown future usage. Now I am wondering whether to provide an OnChange event. And if so, whether to fire it when one or more FileNames.Objects changes. Trying to answer it myself, I dove in Delphi's own VCL and stumbled on: TMemo: has an OnChange event, but ignores Lines.Objects TListBox: has no OnChange event, but is capable of storing Items.Objects TStringGrid: has no OnChange event, but is capable of storing Objects, Rows.Objects, Cols.Objects So now I am somewhat puzzeled, because I cannot imagine Borland's developers didn't add events for several Objects properties out of ease. Sure, when a user changes a FileNames.Object in my component, he knows he does and could implement appropriate interaction himself. But wouldn't it be convenient when the component does automatically? What would you expect from this component in this regard?

  • In search of opinions on web based version control systems

    - by tom smith
    Hi. Researching various open source, web-based document management/version control systems. I've checked google/questions here, etc... I'm looking for a lightweight web-based (apache) document mgmt/version control app that runs on top of SVN. I need to have the ability to: have multiple users checkin/checkout have a workflow (when userA checks the file in, and finishes the app passes it to the next person, etc... the app needs to allow me to have a structure where the files can be moved as a group. the files will be changed on a monthly basis app needs to have a access/premission control system. some people can see certain files, and perform certain actions on the files I imagine that I'm going to have 40-50 people dealing with the different files. I imagine that I'm going to have 2000-3000 files that have to be massaged. I'd prefer that the app be php based if possible, as opposed to a straight java app. Thanks

  • Why are my JavaScript variables not persisting across functions?

    I have the following JavaScript in my HTML page referencing an HTML form on the page: <script type="text/javascript"> <!-- var myForm = document.myForm; function validateForm() { if (myForm.myInput == "") alert("Please input some text."); return false; } myForm.submit(); } function showFormInput() { myForm.reset(); document.getElementById('myInput').style.display = 'inline'; } //--> </script> ... <form name="myForm" id="myForm" action="..." method="post"> <input id="myInput" name="myInput" type="text" value="" style="display:none;" /> </form> Both functions are throwing an exception when trying to access the variable myForm, saying that "myForm is null or not an object". Why is this occurring?
