  • WinForms: Making a set of controls scale vertically.

    - by DonaldRay
    I have a Windows Form that displays several DataGridViews in the following layout: (No access to image hosting at work, so please pardon the ASCII art...) +-----------------------------------------+ ¦+-----------++--------------------------+¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------++--------------------------+¦ +-----------------------------------------+ Unfortunately, when the user resizes the form to be taller, the form ends up looking like this: +-----------------------------------------+ ¦+-----------++--------------------------+¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ | | || | | || |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ | | || | | || |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------++--------------------------+¦ +-----------------------------------------+ Instead of this: +-----------------------------------------+ ¦+-----------++--------------------------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------+¦ ¦¦ |+-----------+¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦¦ ¦+-----------++--------------------------+¦ +-----------------------------------------+ To reproduce this, anchor the Top-Left DataGridView to Top-Left, the Center-Left DataGridView to Left, and the Bottom-Left DataGridView to Bottom-Left, and the big DataGridView to all 4. What can I do to get the behavior I want?

  • emacs frustration with web development

    - by Tony Cruise
    I really liked flexibility of emacs but it is really annoying to make it work. I want to use it for web development html, css, javascript, php. I first tried emacs-starter-kit . It didn't included nXhtml. Also C-g key binding does not work (they call it starter kit but basic key command does not work). I think it is mapped for git control. That's a frustration for a beginner. Then I replaced emacs-starter-kit with nXhtml. At least C-g is working. But code completion sucks, M-tab does not work. I tried code completion from nXhtml menu with no success. Also NXhtml mode did'nt colorized my file if css is mixed with html. Isn't it recommended for mixed html, css,php files. So why it doesnt work?. Why Emacs folks do not aware of convention over configuration? Dam! ship it something works! Please help me before I am getting crazy. I use Ubuntu 10.04 and emacs-snaphot-gtk 23.1.50-1. Please guide step by step with your working dotfile url. Even I accept I am a dummy it really annoying and frustrating to use emacs.

  • WPF: change binding properties for multiple controls

    - by Catalin DICU
    I'd like that all the Text bindings for the TextBoxes in my UserControl to have UpdateSourceTrigger=PropertyChanged, and ValidatesOnDataErrors=True How to do it ? I can think of a solution: use another class for bindings (a class inheriting Binding) but maybe there is another solution, maybe using a style or template ?

  • Using Regex, how can I remove certain characters from inside angle-brackets, leaving the characters

    - by Iain Fraser
    Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

  • jquery validation of controls

    - by Vinodtiru
    Hi , I am looking at validation of some text boxes for somethings like required, minlength, max length, email etc... I am able to get examples that work fine on submit button on page. I want to do this validation on a button click which will only raise a ajax request and not submit of page. On internet all the sample is found was with submit button. Is there a easy way to change this code a little bit o make it work for non submit button click or any new jquery or java plugin to do the same. I am using the jquery.validation.js for now. This works with submit buttons. Any kind of help with suggestion or help is appreciated. Thanks in advance.

  • Dynamically add User Controls to a Silverlight 4 page

    - by PilotBob
    I am building an iGoogle like "dashboard" for our application with silverlight 4. Each users dashboard (which snapins and their positions) will be stored in the database. Each snap in is a user control, for example... AwesomeSnapin.xaml. On the dashboard page in silverlight I am retrieving the users dashboard which is a collection of snapin objects which include the information on the snapin. I can store the name of the page or the class or whatever is needed. I have the following code which loops through the collection of snapins to add them to the dashboard page. In testing I have just hard coded a single snapin item. Here is the prototype code: foreach (var UserSnapin in op.Entities) { UserControl uc = new AmsiSL.eFinancials.BudgetCheck(); Canvas.SetLeft(uc, UserSnapin.PositionLeft); Canvas.SetTop(uc, UserSnapin.PositionTop); Layout.Children.Add(uc); MessageBox.Show(String.Format("Added {0}",UserSnapin.Snapin.Name)); } The above works fine... but of course adds the BudgetCheck snapin for every item that is defined for the users dashboard. Of course the messagebox is for debugging purposes only. How would I change line 3 of that to load the user control class (using classname or xaml path whichever is better) based on the data in the collection.

Thanks for reading this and I need your help .

  • Stop IE users typing into the file upload input

    - by Dexter
    My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted). I am able to replicate this with the following ASPX code (with no code behind): <%@ Page Language="C#" AutoEventWireup="true" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <body> <form id="form1" runat="server"> <div> <asp:FileUpload ID="fuTest" runat="server" /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> </div> </form> </body> </html> (Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box) Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields. I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers. Any thoughts?

  • Accessing other controls by name in a Silverlight ControlTemplate

    - by Chris S
    I have a custom control that inherits from ContentControl. Inside the generic.xaml file is a simple Grid with 2 rows: Row 1 - A toggle button Row 2 - A StackPanel with a TextBlock, named "Stackpanel1" The ToggleButton has its own nested ControlTemplate which has VisualStates for Checked/Unchecked. Is it possible to reference "Stackpanel1" from inside the ToggleButton's control template somehow? In order to show or hide the stackpanel.

  • (C# - windows forms) changing properties of controls that were added at runtime

    - by user257412
    I have a form in which several buttons are added at runtime via a 'for' method public Form() { for (int i = 0 ... ) Button b = new Button() b.text = (string) i ; etc.. etc.. } . now i wish to change the text property of the buttons on a certain event. How can this be accomplished? I have tried a few things but none worked.. since the buttons variables are inside the method , they are not available outside. Thanks

  • Vertical-Align: A Full Explanation

    - by Livvy Jeffs
    I've been struggling with vertical alignments, a seemingly simple enough process that has a lot of idiosyncrasies throughout different languages and element types. I've done a lot of reading through stackexchange and can't seem to find a common thread of understanding. Here are the rules that I have been able to gather: 1) Vertical-align does not work in <\div>s, you have to set div {display: table-cell; vertical-align: middle} This seems like a big hassle, especially since table-cells override the height limitation even when overflow is set to hidden and expands to fit content, which means the vertical "center" is variable. I just read some source-code from Pinterest where button {vertical-align: middle}, but no other vertical-align commands seem to work. It seems as if button is by default aligned in the middle. Can someone provide a clear explanation for the vertical-align attribute? What html elements respond to vertical-align? Which html elements have default vertical-align attributes? Which html elements have non-overridable vertical-align attributes? And any clues as to understanding the idiosyncracies would help as well! Thanks in advance!

  • ActiveX controls with old Delphi versions

    - by DamienD
    I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

  • Type-conditional controls in Haskell

    - by estanford
    I'm going through the 99 Haskell problems to build my proficiency with the language. On problem 7 ("Flatten a nested list structure"), I found myself wanting to define a conditional behavior based on the type of argument passed to a function. That is, since *Main> :t 1 1 :: (Num t) => t *Main> :t [1,2] [1,2] :: (Num t) => [t] *Main> :t [[1],[2]] [[1],[2]] :: (Num t) => [[t]] (i.e. lists nested at different levels have different data types) it seems like I should be able to write a function that can read the type of the argument, and then behave accordingly. My first attempt was along these lines: listflatten l = do if (:t l) /= ((Num t) => [t]) then listflatten (foldl (++) [] l) else id l But when I try to do that, Haskell returns a parse error. Is Haskell flexible enough to allow this sort of type manipulation, do I need to find another way?

  • onmouseover problems with JavaScript (rendered using django and django-imagekit)

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • Mailing Address is forcing 2nd Record in CSV (DevExpress Controls)

    - by Gerhard Weiss
    My DevExpress CSV export has two lines per record. Rank Score,Prog.,Full Address 63.30 ,JIW ,1234 Whispering Pines Dr , ,Sometown MI 48316 62.80 ,JIW ,9876 Beagle Dr , ,Sometown Twp MI 48382 I would like to change it to one line because I want to do a Word Merge. (Unless Word can merge these two lines back together, which I do not thing it can do) Does the DevExpress XtraGrid ExportToText allow for this?

  • UI Controls layer on top of operating system.

    - by Mason Blier
    I'm kind of curious about what layer writing a UI platform to the level of Win32 or the X Windowing System would fall in the grand scheme of an operating system. What layers below do they primarily make use of, is it heavily based on direct communication with the graphics card driver (I can't imagine going though a rendering pipeline like OpenGL for this), or is there a graphical platform as part of the operating system which extracts this out a little more. I'm also interested in the creation of shells and the like, and I"m particularly curious as to how people go about creating alternative shells for windows, what do people look for when figuring out what methods to call or what to hook into, etc? I guess I'm fairly lost at these concepts and finding it difficult to find documentation on them. I was initially excited to have taken Operating Systems in college but it was all low level resource management stuff. Thanks all, Mason
