  • Memory leak when changing Text field of a Scintilla object.

    - by PlaZmaZ
    I have a relatively large program that I'm optimizing for ASCII input files around 10-80mB in size. The program reads every line of the file into a stringbuilder and then sets the Text field of the ScintillNET object to the stringbuilder. The stringbuilder is then set to null. private void ReloadFile(string sFile) { txt_log.ResetText(); try { StringBuilder sLine = new StringBuilder(""); using (StreamReader sr = new StreamReader(sFile)) { while (true) { string temp = sr.ReadLine(); if (temp == null) break; sLine.AppendLine(temp); } sr.Close(); } txt_log.Text = sLine.ToString(); sLine = null; } catch (Exception ex) { MessageBox.Show(this, "An error occurred opening this file.\n\n" + ex.Message, "File Open Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } GC.Collect(); } The program has an option to reload or open a file. This is irrelevant, as any call to txt_log.Text seems to not get rid of the previous memory used for the .Text field. Commenting out the txt_log.Text line gives proper memory behavior. The GC.Collect() line seems pointless, and I have tried both with and without it. Is there something I'm missing here? I HIGHLY doubt it's a problem with the ScintillaNET component itself--rather something in this code.

  • What is this Hash-like/Tree-like Construct Called?

    - by viatropos
    I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context. Here's how I use it: Config.get("root.parent.child_b") #=> "value" Here's what the class might look like: class Construct def get(path) # split path by "." # search tree for nodes end def set(key, value) # split path by "." # create tree node if necessary # set tree value end def tree { :root => { :parent => { :child_a => "value", :child_b => "another value" }, :another_parent => { :something => { :nesting => "goes on and on" } } } } end end Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.

  • javascript function won't stop looping - It's on a netsuite website

    - by Lauren
    I need to change the shipping carrier drop-down and shipping method radio button once via a javascript function, not forever. However, when I use this function, which executes when on the Review and Submit page when the order is < $5, it goes into an endless loop: function setFreeSampShipping(){ var options = document.forms['checkout'].shippingcarrierselect.getElementsByTagName('option'); for (i=0;i<options.length;i++){ if (options[i].value == 'nonups'){ document.forms['checkout'].shippingcarrierselect.value='nonups'; document.forms['checkout'].shippingcarrierselect.onchange(); document.location.href='/app/site/backend/setshipmeth.nl?c=659197&n=1&sc=4&sShipMeth=2035'; } } } It gets called from within this part of the function setSampPolicyElems() which you can see I've commented out to stop the loop: if (carTotl < 5 && hasSampp == 1) { /* if (document.forms['checkout'].shippingcarrierselect.value =='ups'){ setFreeSampShipping(); } */ document.getElementById('sampAdd').style.display="none"; document.getElementById("custbody_ava_webshiptype").value = "7";//no charge free freight if (document.getElementById("applycoupon")) { document.location.href='/app/site/backend/setpromocode.nl?c=659197&n=1&sc=4&kReferralCode=SAMPLE' } document.write("<div id='msg'><strong>Sample & Shipping:</strong></span> No Charge. (Your sample order is < $5.)</div>"); } To see the issue, go to the order review and submit page here: https://checkout.netsuite.com/s.nl?c=659197&sc=4&n=1 (or go to http://www.avaline.com, hit "checkout", and login) You can log in with these credentials: Email:[email protected] Pass:test03

  • Drupal 6 CCK node form redirect issue

    - by swdv
    Hi, I am having trouble with a multi-step node form for a CCK content type. I set $form_state['redirect'] to a thank you page path, but it does not get redirected upon successful submission. Here is the code following documentation on the Drupal 5.x to 6.x form API at http://drupal.org/node/144132 function rnf_form_alter(&$form, &$form_state, $form_id) { // ... $form['#submit'][] = 'rnf_regret_form_submit'; } function rnf_regret_form_submit($form, &$form_state) { $form_state['redirect'] = 'content/forget-thank-you'; } Any help would be appreciated. Thanks.

  • How to compose a Matcher[Iterable[A]] from a Matcher[A] with specs testing framework

    - by Garrett Rowe
    If I have a Matcher[A] how do create a Matcher[Iterable[A]] that is satisfied only if each element of the Iterable satisfies the original Matcher. class ExampleSpec extends Specification { def allSatisfy[A](m: => Matcher[A]): Matcher[Iterable[A]] = error("TODO") def notAllSatisfy[A](m: => Matcher[A]): Matcher[Iterable[A]] = allSatisfy(m).not "allSatisfy" should { "Pass if all elements satisfy the expectation" in { List(1, 2, 3, 4) must allSatisfy(beLessThan(5)) } "Fail if any elements do not satisfy the expectation" in { List(1, 2, 3, 5) must notAllSatisfy(beLessThan(5)) } } }

  • MultiOS "Jet Database" for QtC++?

    - by Airjoe
    Hopefully I can articulate this well: I'm porting an application I made years ago from VB6 (I know, I know!) to QtC++. In my original application, one thing I liked was that I didn't need an actual SQL server running, I could just use MS Access .mdb files. I was wondering if something similar exists for QtC++ that will work on multiple OSes- a database stored in a file, pretty much, but that I can still run SQL queries with. Not sure if something like this exists or not, but any help appreciated, thanks!

  • How would you mask data returned in a Dynamic Data for Entities website?

    - by David Stratton
    I'm doing this in Visual Studio 2008, not 2010, in case there is a relevant difference between the two versions of the Dynamic Data websites. How would I mask data in the automatically generated tables in a Dynamic Data for Entities website? The scenario is we have one table where we want to allow users to ENTER sensitive data, but not VIEW sensitive data, so... (In the list below, I'm using "template" to mean "The web page generated automatically based on the schema and action. I'm sure that's the wrong terminology, but the meaning should be clear.) The "Insert" template should have the field's textbox available for the user to type a value in. The "Edit" template should have the field's textbox blanked out (empty string) regardless of what was in the field in the database in the first place, but the user should be able to type in new data and have it save The "View" template should either have the data for this field masked, or non-visible. The auto-generated table showing the list of records should also have this field masked or non-visible. I can do this easily with standard Web Forms, but I'm having a hard time figuring this out in the Dynamic Data site I'm working on. Masking data is such a common task, I have to believe Microsoft thought of this and provided a way to do it...

  • Programmatically create static arrays at compile time in C++

    - by Hippicoder
    One can define a static array at compile time as follows: const std::size_t size = 5; unsigned int list[size] = { 1, 2, 3, 4, 5 }; Question 1 - Is it possible by using various kinds of metaprogramming techniques to assign these values "programmatically" at compile time? Question 2 - Assuming all the values in the array are to be the same barr a few, is it possible to selectively assign values at compile time in a programmatic manner? eg: const std::size_t size = 7; unsigned int list[size] = { 0, 0, 2, 3, 0, 0, 0 }; Solutions using C++0x are welcome The array may be quite large, few hundred elements long The array for now will only consist of POD types It can also be assumed the size of the array will be known beforehand, in a static compile-time compliant manner. Solutions must be in C++ (no script or codegen based solutions)

  • SQL Server restore a backup results in an error.

    - by Mario
    I have a database in dev (SQL Server 2005 on Windows Server 2008) that I need to move to prod (SQL Server 2000 on Windows Server 2003). My process is as follows: Login to dev, open SQL Server Management Studio Right click on the database | Tasks | Backup. Keep all default options (full backup etc.) Move .bak file locally to prod (no network drive), login to prod, open SQL Server Enterprise Manager. Right click Databases node | All Tasks | Restore database. Change Restore as database to reflect the same database name. Click radio button 'From device'. Click 'Select Devices' Click Restore from: Add..., browse to .bak file (small - only 6mb) Now I am ready to restore the database, so I click OK and get the following error: "The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE DATABASE is terminating abnormally." This error is immediate. I have tried a few different variations of this - restoring the db to dev machine with a different db name and log file names (where it originated), creating an empty database with the same physical path to files before and trying to restore to that, making a few different .bak files and making sure they are verified before uploading them to prod. I know for a fact the directory for the .mdf and .ldf files exist on prod, though the files themselves don't exist. If, before I click OK to restore, go to the options tab instead I get the following error: Error 3241: The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE FILELIST is terminating abnormally. Anyone have any bright ideas?

  • [Apache] mod_rewrite www.site.com/dir/ --> www.site.com/dir/2009/

    - by Casey
    I'm having trouble with this rewrite. I've never really used mod_rewrite before and don't have much experience with regex. Any help is appreciated! <IfModule mod_rewrite.c> Options +FollowSymLinks RewriteEngine on #prevent nested looping RewriteCond %{ENV:REDIRECT_STATUS} ^$ #re-route incoming requests RewriteRule ^(.*)$ %{REQUEST_URI}2009/$1 [L,NE] </IfModule> This partially works, http://www.site.com/dir/ is routed to http://www.site.com/dir/2009/ but a request like http://www.site.com/dir/css/theme.css fails. I'm hoping to rewrite all requests to the parent directory into the 2009 subdirectory but I keep encountering infinite loops and server errors messages. I haven't found any useful examples out there. I figured this would be a common rewrite... Thanks in advance!

  • How can I control which IP address IIS7 uses?

    - by brennanwstehling
    In Win2k3 I used httpcfg to tell IIS to listen to specific IP addresses on the server. I want to run Apache with VisualSVN Server on port 80 on another IP address but IIS7 binds to all ports by default. What utility for IIS7 controls the IIS7 bindings? Update: I found the answer. There is a utility called netsh. netsh http add iplisten ipaddress=xxx.xxx.xxx.xxx By default there are not IP addresses on the list so IIS7 will bind to all IP addressed. If you add one IP to the list it will listen to just that IP or any IP added to the list. It is necessary to restart IIS7 for the change to take affect.

  • Possible to get OpenDNS to dereference Host on VPN?

    - by Scott P
    I recently changed ISPs for my home internet. I am now having some trouble getting back into the corporate network from home over the VPN. I have figured out the OpenDNS is resolving the Hosts on the VPN incorrectly when I am using TCP/IP. When I browse to one of the hosts on corporate network, i.e. \host1, from the file manager this succeeds. However, when I ping the host, i.e. ping host1, the IP address is resolving to the OpenDNS name server instead of the actual Host IP address. Does anyone know how to make this work? On a hunch, I turned off type correction. But, this did not help.

  • How to disable the green power light on the Sony Vaio

    - by sri
    The Sony Vaio's green power light is extremely bright and very distracting! I can't even look at the screen without this power light being in my view!! Is there any way to disable it or reduce its intensity? Googling for "sony vaio disable green power light" (and similar combinations) didn't provide anything useful. I tried booting into the BIOS, but it didn't have an option for this. Also, the Viao Command Center didn't have any on it. I guess sticking a tape over the LED is the only option? Any help is greatly appreciated! Thanks!

  • Which parts of Graphics Pipelines are done using CPU & GPU?

    - by afriza
    Which parts of pipelines are done using CPU and which are done using GPU? Reading Wikipedia on Graphics Pipeline, maybe my question does not precisely represent what I am asking. Referring to this question, which "steps" are done in CPU and which are done in GPU? Edit: My question is more into which parts of logical high level steps needed to display terrain+3D models are using CPU/GPU instead of which functions.

  • Moq Testing a private method .Many posts but still cannot make one example work

    - by devnet247
    Hi, I have seen many posts and questions about "Mocking a private method" but still cannot make it work and not found a real answer. Lets forget the code smell and you should not do it etc.... From what I understand I have done the following: 1) Created a class Library "MyMoqSamples" 2) Added a ref to Moq and NUnit 3) Edited the AssemblyInfo file and added [assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")] [assembly: InternalsVisibleTo("MyMoqSamples")] 4) Now need to test a private method.Since it's a private method it's not part of an interface. 5) added the following code [TestFixture] public class Can_test_my_private_method { [Test] public void Should_be_able_to_test_my_private_method() { //TODO how do I test my DoSomthing method } } public class CustomerInfo { public string Name { get; set; } public string Surname { get; set; } } public interface ICustomerService { List<CustomerInfo> GetCustomers(); } public class CustomerService: ICustomerService { public List<CustomerInfo> GetCustomers() { return new List<CustomerInfo> {new CustomerInfo {Surname = "Bloggs", Name = "Jo"}}; } protected virtual void DoSomething() { } } Could you provide me an example on how you would test my private method? Thanks a lot

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?
