  • VB.NET template instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine repoGeneric = New Repositories.Repository(Of SelectedType) 'Ba-bow! repoGeneric = New Repositories.Repository(Of InstanceOfMyClass.GetType()) 'Ba-bow! I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

  • How to change a variable type in C#?

    - by Mosho Mulan
    I wanted to use something like this: if(x==5) { var mydb= ........ ; } else { var mydb = ........ ; } but it didn't work because I can't declare a variable inside if statement. So I tried to do this: var mydb; if (x==5) { mydb= ............. ; } else { mydb=.............; } but id didn't work either because I had to initialize the variable (mydb). So the question is: I don't necessarily know the type of the variable, can I declare it anyway and then change the type inside the if statement?

  • saving a records containing a member of type string to a file (Delphi, Windows)

    - by wonderer
    I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

  • Pass parameter one time, but use more times

    - by Gabriel L. Oliveira
    I'm trying to do this: commands = { 'py': 'python %s', 'md': 'markdown "%s" "%s.html"; gnome-open "%s.html"', } commands['md'] % 'file.md' But like you see, the commmands['md'] uses the parameter 3 times, but the commands['py'] just use once. How can I repeat the parameter without changing the last line (so, just passing the parameter one time?)

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  • Constructor type not found

    - by WaffleTop
    Hello, What I am doing: I am taking the Microsoft Enterprise Library 4.1 and attempting to expand upon it using a few derived classes. I have created a MyLogEntry, MyFormatter, and MyTraceListener which derive from their respective base classes when you remove the "My" from their names. What my problem is: Everything compiles fine. When I go to run a test using Logger.Write(logEntry) it errors right after it initializes MyTraceListener with an error message: "The current build operation (... EnterpriseLibrary.Logging.LogWriter, null]) failed: Constructor on type 'MyLogging.MyFormatter' not found. (Strategy type ConfiguredObjectStrategy, index 2) I figured it was something to do with the constructor so I tried removing it, add it, and adding a call to the base class LogFormatter. Nothing has worked. Does anyone have insight into this problem? Is it maybe a reference issue? Bad App.config configuration? Thank you in advance

  • Unknown attribute xsi:type in XmlSerializer

    - by vanccoon
    I am learning XML Serialization and meet an issue, I have two claess [System.Xml.Serialization.XmlInclude(typeof(SubClass))] public class BaseClass { } public class SubClass : BaseClass { } I am trying to serialize a SubClass object into XML file, I use blow code XmlSerializer xs = new XmlSerializer(typeof(Base)); xs.Serialize(fs, SubClassObject); I noticed Serialization succeed, but the XML file is kind of like ... If I use XmlSerializer xs = new XmlSerializer(typeof(Base)); SubClassObject = xs.Deserialize(fs) as SubClass; I noticed it will complain xsi:type is unknown attribute(I registered an event), although all information embedded in the XML was parsed successfully and members in SubClassObject was restored correctly. Anyone has any idea why there is error in parsing xsi:type and anything I did wrong? Thanks

  • Mercurial merge strategy per file type

    - by dls
    All: I want to use kdiff to merge all files with a certain suffix (say *.c, *.h) and I want to do two things (turn off premerge and use internal:other) for all files with another suffix (say *.mdl). The purpose of this is to allow me to employ a type of 'clobber merge' for a specific file type (ie: un-mergable files like configurations, auto-generated C, models, etc..) In my .hgrc I've tried: [merge-tools] kdiff3= clobbermerge=internal:other clobbermerge.premerge = False [merge-patterns] **.c = kdiff3 **.h = kdiff3 **.mdl = clobbermerge but it still triggers kdiff3 for all files. Thoughts? An extension of this would be to perform a 'clobber merge' on a directory - but once the syntax is clear for a file suffix, the dir should be easy.

  • Core Data data type for just the date - not including time

    - by Jason
    I am new at Core Data, and it seems like it is a great way to manage the data store. However I am also very memory-conscious due to the fact that the iPhone doesn't have that much of it. I was a little surprised to see that the data types are so limited - eg. there is a Date type which includes also the time, but no Date type for just the date! All the time information takes up precious bytes of memory, if I just wanted an attribute with the date (e.g. 2/15/2010 rather than 2/15/2010 02:34:48), how could I do this? Is it possible?

  • How to properly encode "[" and "]" in queries using Apache HttpClient?

    - by Jason Nichols
    I've got a GET method that looks like the following: GetMethod method = new GetMethod("http://host/path/?key=[\"item\",\"item\"]"); Such a path works just fine when typed directly into a browser, but the above line when run causes an IllegalArgumentException : Invalid URI. I've looked at using the URIUtils class, but without success. Is there a way to automatically encode this (or to add a query string onto the URL without causing HttpClient to barf?).

  • How to call the previous querystring parameter in .aspx

    - by Ingó Vals
    Let's say I have a ActionResult method that has a pageNumber parameter and a category parameter. The user should be able to set the category he's browsing which would be a ActionLink to the first page of that category. However if I have an another ActionLink where I go to the next page the category parameter would go back to default. How can I set the category parameter to be the same as on the previous page.

  • Ignore route with a specific parameter

    - by Vivien
    Hello, I have an @url.Action in which I pass a parameter to the action. When the parameter is null, I would like to just do nothing and stay on the same page. What I have done is the following: routes.MapRoute( null, "Test/View/{Id}", new { controller = "Test", action = "View" }, new { Id = @"\d+" } //id must be numerical ); routes.IgnoreRoute("Test/View/{*pathInfo}"); The action is not executed but my problem is that I get this: Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Test/View Which I obvisouly do not want to see. Thanks for your help.

  • How to know file type without extension

    - by Ayusman
    While trying to come-up with a servlet based application to read files and manipulate them (image type conversion) here is a question that came up to me: Is it possible to inspect a file content and know the filetype? Is there a standard that specifies that each file MUST provide some type of marker in their content so that the application will not have to rely on the file extension constraints? Consider an application scenario: I am creating an application that will be able to convert different file formats to a set of output formats. Say user uploads an PDF, my application can suggest that the possible conversion formats are microsoft word or TIFF or JPEG etc. As my application will gradually support different file formats (over a period of time), I want my application to inspect the input file instead of having the user to specify the format. And suggest to user the possible formats of output. I understand this is an open ended, broad question. Please let me know if it needs to be modified. Thanks, Ayusman

  • How do I get parameters between activities?

    - by Matt
    I am working on an app that has multiple tabs. In the first tab the user will enter values. In the other tabs it will display the results of calculations based off of those values. Like in tab 1, the user will enter "3" and "2". In tab 2, the program will add them and display "5". In tab 2 how do I access the ints "3" and "2"? Thanks

  • context.Scale() with non-aspect ratio preserving parameters screws effective lineWith

    - by rrenaud
    I am trying to apply some natural transformations whereby the x axis is remapped to some very small domain, like from 0 to 1, whereas y is remapped to some small, but substantially larger domain, like 0 to 30. This way, drawing code can be nice and clean and only care about the model space. However, if I apply a scale, then lines are also scaled, which means that horizontal lines become extremely fat relative to vertical ones. Here is some sample code. When natural_height is much less than natural_height, the picture doesn't look as intended. I want the picture to look like this, which is what happens with a scale that preserves aspect ratio. rftgstats.c om/canvas_good.png However, with a non-aspect ratio preserving scale, the results look like this. rftgstats.c om/canvas_bad.png <html><head><title>Busted example</title></head> <body> <canvas id=example height=300 width=300> <script> var canvas = document.getElementById('example'); var ctx = canvas.getContext('2d'); var natural_width = 10; var natural_height = 50; ctx.scale(canvas.width / natural_width, canvas.height / natural_height); var numLines = 20; ctx.beginPath(); for (var i = 0; i < numLines; ++i) { ctx.moveTo(natural_width / 2, natural_height / 2); var angle = 2 * Math.PI * i / numLines; // yay for screen size independent draw calls. ctx.lineTo(natural_width / 2 + natural_width * Math.cos(angle), natural_height / 2 + natural_height * Math.sin(angle)); } ctx.stroke(); ctx.closePath(); </script> </body> </html>

  • mvc consistent route parameters without re-initializing every action

    - by Ayo
    Trying to consistently tack on a route parameter for every action without having to set it every action I tried this with ViewData but it seems ineffecient to do to every action. when I have over 40-50 actions, and Sessions are a no go for me. Is there a simpler way through filters or something else I could use? eg. http://localhost/myController/myView?param=foo eg. http://localhost/myController/myView/myID?param=foo (needs to be tacked on id automatically)

  • determine which value produced a hit in SOLR multivalued field type

    - by harschware
    If I have a multiValued field type of text, and I put values [cat,dog,green,blue] in it. Is there a way to tell when I execute a query against that field for dog, that it was in the 1st element position for that multiValued field? Assumption: client does not have any pre-knowledge of what the field type of the field being queried is. (i.e. Solr must provide the answer and the client can't post process the return doc to figure it out because it would not know how SOLR matched the query to the result). Disclosure: I posted to solr-user list and am getting no traction so I post here now.

  • Best approach to limit users to a single node of a given content type in Drupal

    - by Chaulky
    I need to limit users to a single node of a given content type. So a user can only create one node of TypeX. I've come up with two approaches. Which would be better to use... 1) Edit the node/add/typex menu item to check the database to see if the user has already created a node of TypeX, as well as if they have permissions to create it. 2) When a user creates a node of TypeX, assign them to a different role that doesn't have permissions to create that type of node. In approach 1, I have to make an additional database call on every page load to see if they should be able to see the "Create TypeX" (node/add/typex). But in approach 2, I have to maintain two separate roles. Which approach would you use?

  • ArgumentException or ArgumentNullException for string parameters?

    - by Anna Lear
    Far as best practices are concerned, which is better: public void SomeMethod(string str) { if(string.IsNullOrEmpty(str)) { throw new ArgumentException("str cannot be null or empty."); } // do other stuff } or public void SomeMethod(string str) { if(str == null) { throw new ArgumentNullException("str"); } if(str == string.Empty) { throw new ArgumentException("str cannot be empty."); } // do other stuff } The second version seems more precise, but also more cumbersome than the first. I usually go with #1, but figured I'd check if there's an argument to be made for #2.

  • Specify More "case" in switch parameters

    - by Sophie Mackeral
    I have the following code: $ErrorType = null; switch ($ErrNo){ case 256,1: $ErrorType = "Error"; break; case 512,2: $ErrorType = "Warning"; break; case 1024,8: $ErrorType = "Notice"; break; case 2048: $ErrorType = "Strict Warning"; break; case 8192: $ErrorType = "Depreciated"; break; } But the problem is, I'm going from the pre-defined constants for an error handling software solution.. I cannot specify more than one "case" for the dedicated error categories, example: switch ($ErrNo){ case 1: $ErrorType = "Error"; break; case 256: $ErrorType = "Error"; } That's a repeat of code.. Whereas with a solution like my first example, it would be beneficial as two integers fall under the same category.. Instead, i'm returned with the following: Parse error: syntax error, unexpected ',' in Action_Error.php on line 37
