• HTML Select and Text Input

  - by Vijay Dev

  We have all seen countless instances of forms with a select drop down having one of it's options as "Other" and on choosing that option, we get to see a input text box (which was hidden all along) asking us to type in our input. Is there a better way to implement this? Are there plugins out there which will let me do this better? Or are standard HTML elements suffice (some setting to a , may be) ?

• AutoScaleMode problems with changed default font

  - by Doc Brown

  Hi, I have some problems with the Form.AutoScaleMode property together with fixed size controls, when using a non-default font. I boiled it down to a simple test application (WinForms 2.0) with only one form, some fixed size controls and the following properties: class Form1 : Form { // ... private void InitializeComponent() { // ... this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Font = new System.Drawing.Font("Tahoma", 9.25F); // ... } } Under 96dpi, Windows XP, the form looks correctly like this 96 dpi example. Under 120 dpi, Windows XP, the the Windows Forms autoscaling feature produces this 120 dpi example. As you can see, groupboxes, buttons, list or tree views are scaled correctly, multiline text boxes get too big in the vertical axis, and a fixed size label does not scale correctly in both vertical and horizontal direction. Seems to be bug in the .NET framework? Using the default font (Microsoft Sans Serif 8.25pt), this problem does not occur. Using AutoScaleMode=Font (with adequate AutoScaleDimensions, of course) either does not scale at all or scales exactly like seen above, depending on when the Font is set (before or after the change of AutoScaleMode). The problem is not specific to the "Tahoma" Font, it occurs also with Microsoft Sans Serif, 9.25pt. And yes, i already read this SO post http://stackoverflow.com/questions/2114857/high-dpi-problems but it does not really help me. Any suggestions how to come around this? EDIT: I changed my image hoster, hope this one works better. EDIT2: Some additional information about my intention: I have about 50 already working fixed size dialogs with several hundreds of properly placed, fixed size controls. They were migrated from an older C++ GUI framework to C#/Winforms, that's why they are all fixed-size. All of them look fine with 96 dpi using a 9.25pt font. Under the old framework, scaling to 120 dpi worked fine - all fixed size controls scaled equal in both dimensions. Last week, we detected this strange scaling behaviour under WinForms when switching to 120 dpi. You can imagine that most of our dialogs now look very bad under 120 dpi. We are looking for a solution that avoids a complete redesign all those dialogs.

• wpf and win32 overlapping issue

  - by priya-hatipkar

  I have a wpf Window, which has wpf control and windows forms control hosted in WindowsFormsHost. The expected behavior is that the WPF control should be rendered on top of WindowsFormsHost. Unfortunately, this is a limitation in the interop story, WindowsFormsHost elements are always drawn on top, and don't get affected by z-order. http://msdn.microsoft.com/en-us/library/ms742522.aspx Is there any workaround to solve this problem? Regards, Priya

• PartialResultException when authenticating over LDAP with Acegi and Grails

  - by Benny Hallett

  I'm trying to setup our new Grails application to authenticate via LDAP. From the logs we can see that Acegi is binding to the LDAP store, then is able to find the user given the correct credentials, and finally begins searching for roles. The authentication fails due to a PartialResultException. I'm aware that the default LDAP provider in Acegi has an option to ignore PartialResultExceptions, but I'm not exactly sure how to turn that on in Grails.

• Programatically creating a Site Workflow in SharePoint 2010?

  - by Michael Stum

  I'm trying to create a new Site Workflow, but not through SP Designer or Visual Studio. Instead, I would need to create it entirely through code (The logic is customizable and dynamic - Initiation Forms or Conditionals won't help much). Do I have to build the .xoml and .rules files by hand? Or is there an API for designing workflows?

• html5 video secure streaming?

  - by citizenmatt

  Does html5 allow me to do secure streaming video? And by this, I mean token authentication. I want to be able to stream media only to those people who are authorised to view it. I can do this currently with Flash Media Server hosted by Akamai - they have a custom mechanism where I send them a token as part of the player connection handshake. Does html5 allow for this, and has anyone implemented this with a hosting service such as Akamai? Thanks Matt

• How do I encrypt property values in Nant?

  - by Diego C.

  I need to store authentication information and I rather not have the password in plain text: <property name="user" value="theUser"/> <property name="password" value="secret"/> Has anyone figured out a way to encrypt property values in Nant? I've looked in Nant and Nantcontrib docs but no mention of encryption. I am considering going the route of creating my own Nant Task. Any suggestions?

• DUnit: How to run tests?

  - by Ian Boyd

  How do i run TestCase's from the IDE? i created a new project, with a single, simple, form: unit Unit1; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) private public end; var Form1: TForm1; implementation {$R *.DFM} end. Now i'll add a test case to check that pushing Button1 does what it should: unit Unit1; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private public end; var Form1: TForm1; implementation {$R *.DFM} uses TestFramework; type TForm1Tests = class(TTestCase) private f: TForm1; protected procedure SetUp; override; procedure TearDown; override; published procedure TestButton1Click; end; procedure TForm1.Button1Click(Sender: TObject); begin //todo end; { TForm1Tests } procedure TForm1Tests.SetUp; begin inherited; f := TForm1.Create(nil); end; procedure TForm1Tests.TearDown; begin f.Free; inherited; end; procedure TForm1Tests.TestButton1Click; begin f.Button1Click(nil); Self.CheckEqualsString('Hello, world!', f.Caption); end; end. Given what i've done (test code in the GUI project), how do i now trigger a run of the tests? If i push F9 then the form simply appears: Ideally there would be a button, or menu option, in the IDE saying Run DUnit Tests: Am i living in a dream-world? A fantasy land, living in a gumdrop house on lollipop lane?

• API for parse/update UNIX configuration files

  - by Chen Levy

  Unix configuration files come in all shapes and forms. I know that Webmin has a Perl API that makes it easy to parse and modify most common configuration pro grammatically, while preserving changes that might have been made by hand. Are there any other libraries that has similar functionality, perhaps for other languages (Python, Ruby, C, C++, etc)?

• Problem with Keyboard hook proc

  - by Steve

  The background: My form has a TWebBrowser. I want to close the form with ESC but the TWebBrowser eats the keystrokes - so I decided to go with a keyboard hook. The problem is that the Form can be open in multiple instances at the same time. No matter what I do, in some situations, if there are two instances open of my form, closing one of them closes the other as well. I've attached some sample code. Any ideas on what causes the issue? var EmailDetailsForm: TEmailDetailsForm; KeyboardHook: HHook; implementation function KeyboardHookProc(Code: Integer; wParam, lParam: LongInt): LongInt; stdcall; var hWnd: THandle; I: Integer; F: TForm; begin if Code < 0 then Result := CallNextHookEx(KeyboardHook, Code, wParam, lParam) else begin case wParam of VK_ESCAPE: if (lParam and $80000000) <> $00000000 then begin hWnd := GetForegroundWindow; for I := 0 to Screen.FormCount - 1 do begin F := Screen.Forms[I]; if F.Handle = hWnd then if F is TEmailDetailsForm then begin PostMessage(hWnd, WM_CLOSE, 0, 0); Result := HC_SKIP; break; end; end; //for end; //if else Result := CallNextHookEx(KeyboardHook, Code, wParam, lParam); end; //case end; //if end; function TEmailDetailsForm.CheckInstance: Boolean; var I, J: Integer; F: TForm; begin Result := false; J := 0; for I := 0 to Screen.FormCount - 1 do begin F := Screen.Forms[I]; if F is TEmailDetailsForm then begin J := J + 1; if J = 2 then begin Result := true; break; end; end; end; end; procedure TEmailDetailsForm.FormCreate(Sender: TObject); begin if not CheckInstance then KeyboardHook := SetWindowsHookEx(WH_KEYBOARD, @KeyboardHookProc, 0, GetCurrentThreadId()); end; procedure TEmailDetailsForm.FormDestroy(Sender: TObject); begin if not CheckInstance then UnHookWindowsHookEx(KeyboardHook); end;

• Why do ASP.NET applications appear to be running in a terminal server session?

  - by Heinzi

  Running the following ASPX page (IIS 6, Server 2003 R2) <%@ Page Language="vb" AutoEventWireup="false" %> <% Response.Write("Am I running in a terminal server session: " & _ System.Windows.Forms.SystemInformation.TerminalServerSession) %> yields the following output: Am I running in a terminal server session: True Why? IIS is running as a service, not as a Terminal Services application... (BTW, according to Reflector, SystemInformation.TerminalServerSession is just a wrapper for GetSystemMetrics(SM_REMOTESESSION).)

When I initialise my Django form in a view, I would like to pass the image path as a parameter, and the form when rendered in the template displays the image. Is is possible with Django forms or would i have to display the image separately? Thanks.

• Problems related to showing MessageBox from non-GUI threads

  - by Hans Løken

  I'm working on a heavily data-bound Win.Forms application where I've found some strange behavior. The app has separate I/O threads receiving updates through asynchronous web-requests which it then sends to the main/GUI thread for processing and updating of application-wide data-stores (which in turn may be data-bound to various GUI-elements, etc.). The server at the other end of the web-requests requires periodic requests or the session times out. I've gone through several attempted solutions of dealing with thread-issues etc. and I've observed the following behavior: If I use Control.Invoke for sending updates from I/O-thread(s) to main-thread and this update causes a MessageBox to be shown the main form's message pump stops until the user clicks the ok-button. This also blocks the I/O-thread from continuing eventually leading to timeouts on the server. If I use Control.BeginInvoke for sending updates from I/O-thread(s) to main-thread the main form's message pump does not stop, but if the processing of an update leads to a messagebox being shown, the processing of the rest of that update is halted until the user clicks ok. Since the I/O-threads keep running and the message pump keeps processing messages several BeginInvoke's for updates may be called before the one with the message box is finished. This leads to out-of-sequence updates which is unacceptable. I/O-threads add updates to a blocking queue (very similar to http://stackoverflow.com/questions/530211/creating-a-blocking-queuet-in-net/530228#530228). GUI-thread uses a Forms.Timer that periodically applies all updates in the blocking queue. This solution solves both the problem of blocking I/O threads and sequentiality of updates i.e. next update will be never be started until previous is finished. However, there is a small performance cost as well as introducing a latency in showing updates that is unacceptable in the long run. I would like update-processing in the main-thread to be event-driven rather than polling. So to my question. How should I do this to: avoid blocking the I/O-threads guarantee that updates are finished in-sequence keep the main message pump running while showing a message box as a result of an update.

• MS Access group development

  We are planning to redesign quite a huge MS Access application. Is there any way to work concurently on the same application or is it possible to merge two seperate instance of the same file (not the data, but the forms and code). Now Access contains the data, but in the future version MySQL will host the data and Access will be only the frontend (via ODBC)

• Help organising controllers logically

  - by kenny99

  Hi guys, I'm working on a site which i'm developing using an MVC structure. My models will represent all of data in the site, but i'm struggling a bit to decide on a good controller structure. The site will allow users to login/register and see personal data on a number of pages, but also still have access to public pages, e.g FAQs, Contact page etc. This is what I have at the moment... A Template Controller which handles main template display. The basic template for the site will remain the same whether or not you are logged in. A main Website Controller which extends the Template Controller and handles basic authentication. If the user is logged in, a User::control_panel() method is called from the constructor and this builds the control panel which will be present throughout the authenticated session. If user is not logged in, then a different view is loaded instead of the control panel, e.g with a login form. All protected/public page related controllers will extend the website controller. The user homepage has a number of widgets I want to display, which I'm doing via a Home Controller which extends the Website Controller. This controller generates these widgets via the following static calls: $this->template->content->featured_pet = Pet::featured(); $this->template->content->popular_names = Pet::most_popular(); $this->template->content->owner_map = User::generate_map(); $this->template->content->news = News::snippet(); I suppose the first thing I'm unsure about is if the above static calls to controllers (e.g Pet and User) are ok to remain static - these static methods will return views which are loaded into the main template. This is the way I've done things in the past but I'm curious to find out if this is a sensible approach. Other protected pages for signed in users will be similar to the Home Controller. Static pages will be handled by a Page Controller which will also extend the Website Controller, so that it will know whether or not the user control panel or login form should be shown on the left hand side of the template. The protected member only pages will not be routed to the Page Controller, this controller will only handle publicly available pages. One problem I have at the moment, is that if both public and protected pages extend the Website Controller, how do I avoid an infinite loop - for example, the idea is that the website controller should handle authentication then redirect to the requested controller (URL), but this will cause an infinite redirect loop, so i need to come up with a better way of dealing with this. All in all, does this setup make any sense?! Grateful for any feedback.

• drupal module alter view or node

  I have been using hook_alter to modify forms in a custom PHP module. I started to take the same approach modifying the result page of "node add" form. However this page is not a form so I don't have a form ID to hook on to. Actually it contains a login form, but that does not contain the elements that I am looking for, What approach should I use in this situation?
