  • (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

  • 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.

  • 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.

  • 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?

  • onLoad focus() event within jquerytools overlay effect

    - by tomcritchlow
    Hi, I'm using the overlay jquery from here: http://flowplayer.org/tools/overlay/index.html Within my overlay I have a search box like this: <div class="simple_overlay" id="asearch"> <div id="searchbox"> <form id="amazonsearch" style='float:left;'> <input class="title" id="amazon-terms" style="width:400px;font-size:2em;"> <button class="sexybutton sexysimple sexygreen">Search</button> </form> <div id="amazon-results"></div> </div><!--seachbox--> </div><!--Overlay--> What I want to happen is when you load the overlay the search box within the overlay gains focus so you can start typing into it. I thought that this would work: $("a[rel]").overlay({ onLoad: function() { $('#amazon-terms').focus(); } }); But that doesn't seem to do anything. I know the event is firing because this works: $("a[rel]").overlay({ onLoad: function() { alert('popup opened') } }); However, when this alert fires the overlay has not yet appeared on the screen so I wonder if that is part of the problem? According to the docs onLoad should fire "when the overlay has completely been displayed" (ref) Any help appreciated! :) Thanks Tom EDIT This code does what I want it to but I'm none the wiser as to why this works when the code above doesn't.... var triggers = $("a[rel]").overlay({ closeOnClick: false, onLoad: function() { $('input').focus(); } });

  • 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? A MemoEdit is being used by the XtraGrid and is initialized using the following code (Noticed the ControlChars.NewLine): Public ReadOnly Property FullAddress() As String Get Dim strAddress As System.Text.StringBuilder = New StringBuilder() If Not IsNullEntity Then strAddress.Append(Line1 + ControlChars.NewLine) If Not Line2 Is Nothing AndAlso Me.Line2.Length > 0 Then strAddress.Append(Line2 + ControlChars.NewLine) End If If Not Line3 Is Nothing AndAlso Me.Line3.Length > 0 Then strAddress.Append(Line3 + ControlChars.NewLine) End If strAddress.Append(String.Format("{0} {1} {2}", City, RegionCode, PostalCode)) If Me.Country <> "UNITED STATES" Then strAddress.Append(ControlChars.NewLine + Me.Country) End If End If Return strAddress.ToString End Get End Property Here is the export to CSV code: Dim saveFile As New SaveFileDialog With saveFile '.InitialDirectory = ClientManager.CurrentClient.Entity.StudentPictureDirectory .FileName = "ApplicantList.csv" .CheckPathExists = True .CheckFileExists = False .Filter = "All Files (*.*)|*.*" End With If saveFile.ShowDialog() = Windows.Forms.DialogResult.OK Then Dim PrintingTextExportOptions As New DevExpress.XtraPrinting.TextExportOptions(",", Encoding.ASCII) PrintingTextExportOptions.QuoteStringsWithSeparators = True ApplicantRankListViewsGridControl.ExportToText(saveFile.FileName, PrintingTextExportOptions) End If

  • Collapsible controls in MFC (example included)

    - by John
    In the WindowsXP Control panel, you can see a nice collapsible panel control on the left: These are not just collapsible, but animated too. I wondered if these are any kind of control accessible to a developer, specifically in MFC? Or are they custom/bespoke functionality?

  • Question about migrating from ASP .NET User Controls to .NET 3.5 Master Page technology

    - by Jim McFetridge
    When migrating from an ASP .NET user control -based page with a header, footer, and menu to a Master Page using the same HTML mark-up, is it normal for CSS or javascript behaviors to change slightly? In particular, the submenu bar text now appears run together (which looks like a CSS symptom) and the graphics on the line above it appear to have an incorrect z-order. (The menu operation is javascript-based.) (I tried to paste images here but couldn't.) Also, the site is very large and we've not been given permission to redo the menu for the entire site. This is a forward-only migration. (Because I know that someone will ask.) Assuming that there are no changes in scope, what are the things that I should check? Thanks! Jim

  • PHP preg_replace - Don't match within h1 tags

    - by James
    Hi there. I am using preg_replace to add a link to keywords if they are found within a long HTML string. I don't want to add a link if the keyword is found within h1 tags or strong tags. The below regex nearly works and basically says (I think): If the keyword is not immediately wrapped by either a h1 tag or a strong tag then replace with the keyword that was matched, as a bolded link to google. $result = preg_replace('%(?!<h1>)(?!<strong>)\b(bobs widgets)\b(?!<\/strong>)(?!<\/h1>)%i','<a href="http://www.google.com"><strong>$1</strong></a>', $result, -1); (the reason I don't want to match if in strong tags is because I am recursing through a lot of keywords so don't want to link an already linked keyword on subsequent passes) the above works fine and won't match: <h1>bobs widgets</h1> It will however match the keyword in the following text, because the h1 tag isn't immediately either side of the keyword: <h1>Here are bobs widgets for sale</h1> I need to make the spaces either side optional and have tried adding \s* but that doesn't get me anywhere. I'd be very grateful for a push in the right direction here.

  • 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

  • Unit testing "hybrid" WPF/Silverlight controls

    - by Alan Mendelevich
    I'm starting a new WPF/Silverlight custom control project and wanted to do unit testing on this one. However I'm a little confused about how to approach this. This control would be based on the same codebase for both WPF and Silverlight with minor forking using #ifs and partial classes to tame the differences. I guess I could write unit tests for WPF part with NUnit, MSTest, xUnit, etc. and for the Silverlight part with Silverlight Unit Test Framework but this doesn't sound very elegant to me. I'd have to either ignore testing identical code on one of the platforms and test only differing parts (which is not very trustworthy) or rewrite tests for 2 frameworks (which is annoying). Is this the right way to go? I'm wondering if there's some guidance, articles, tutorials out there on how to approach this task. Any pointers?

  • How to use javascript class from within document ready

    - by Richard
    Hi, I have this countdown script wrapped as an object located in a separate file Then when I want to setup a counter, the timeout function in the countdown class can not find the object again that I have setup within the document ready. I sort of get that everything that is setup in the document ready is convined to that scope, however it is possible to call functions within other document ready´s. Does anyone has a solution on how I could setup multiple counters slash objects. Or do those basic javascript classes have to become plugins This is some sample code on how the class begins function countdown(obj) { this.obj = obj; this.Div = "clock"; this.BackColor = "white"; this.ForeColor = "black"; this.TargetDate = "12/31/2020 5:00 AM"; this.DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; this.CountActive = true; this.DisplayStr; this.Calcage = cd_Calcage; this.CountBack = cd_CountBack; this.Setup = cd_Setup; } thanks, Richard

  • Calling a method within Portlet when submitting form

    - by Roland
    I have a Portlet that contains a form. Now what I want to achieve is the following. 1) A Porlet containing a form is called within a page via <?php $this->widget('form'); ?> 2) The user fills in this form and clicks on submit "The submit button should be an ajax button" 3) When submit has been pressed the form should call a method within the form portlet class and the form should be replaced with a Thank you message. 4) I only want the current view in the portlet replaced with another view. My portlet class looks like this Yii::import('zii.widgets.CPortlet'); class Polls extends CPortlet{ public $usr_id=''; public function init(){ $cs = Yii::app()->clientScript; $cs->registerCoreScript('jquery'); parent::init(); } protected function renderContent(){ $this->render('form'); } public function update(){ $this->render('thankyou'); } } } Any advise, help would be highly appreciated.

  • casting, converting, and input from textbox controls

    - by Matt
    Working on some .aspx.cs code and decided I would forget how to turn a textbox value into a useable integer or decimal. Be warned I'm pretty new to .asp. Wish I could say the same for c sharp. So the value going into my textbox (strawberryp_textbox) is "1" which I presume I can access with the .text property. Which I then parse into a int. The Error reads Format Exception was unhandled by user code. My other question is can I do operations on a session variable? protected void submit_order_button_Click(object sender, EventArgs e) { int strawberryp; int strawberrys; decimal money1 = decimal.Parse(moneybox1.Text); decimal money2 = decimal.Parse(moneybox2.Text); decimal money3 = decimal.Parse(moneybox3.Text); decimal money4 = decimal.Parse(moneybox4.Text); decimal money5 = decimal.Parse(moneybox5.Text); strawberryp = int.Parse(strawberryp_Textbox.Text); //THE PROBLEM RIGHT HERE! strawberrys = int.Parse(strawberrys_Textbox.Text); // Needs fixed int strawberryc = int.Parse(strawberryc_Textbox.Text); //fix int berryp = int.Parse(berryp_Textbox.Text); //fix int raspberryp = int.Parse(raspberryp_Textbox.Text); /fix decimal subtotal = (money1 * strawberryp) + (money2 * strawberrys) + (money3 * strawberryc) + (money4 * berryp) + (money5 * raspberryp); //check to see if you can multiply decimal and int to get a deciaml!! Session["passmysubtotal"] = subtotal; //TextBox2.Text; (strawberryp_Textbox.Text);//TextBox4.Text; add_my_order_button.Enabled = true; add_my_order_button.Visible = true; submit_order_button.Enabled = false; submit_order_button.Visible = false; strawberryp_Textbox.ReadOnly = false; strawberrys_Textbox.ReadOnly = false; strawberryc_Textbox.ReadOnly = false; berryp_Textbox.ReadOnly = false; raspberryp_Textbox.ReadOnly = false; Response.Redirect("reciept.aspx"); } Thanks for the help

  • Override ~ behaviour in controls

    - by cpf
    Quick backstory: I'm making a "framed" version of my site that has a different master page than normal (one suitable for iframing). It's accessed by mysite.com/Framed/whatever, instead of mysite.com/whatever. This is rewritten in IIS to mysite.com/whatever?framed=true. That works fine. The issue I'm having is that all the links are relative using a ~ like ~/Server.aspx which works fine in the normal site. I need to override that so instead of producing ../Server.aspx (as it "should") it produces ../Framed/Server.aspx or Server.aspx. Currently this means that the page goes back to it's normal view (mystite.com/whatever2) as soon as you click on a link, I want it to continue to stay in mysite.com/Framed/...

  • Output reformatted text within a file included in a JSP

    - by javanix
    I have a few HTML files that I'd like to include via tags in my webapp. Within some of the files, I have pseudo-dynamic code - specially formatted bits of text that, at runtime, I'd like to be resolved to their respective bits of data in a MySQL table. For instance, the HTML file might include a line that says: Welcome, [username]. I want this resolved to (via a logged-in user's data): Welcome, [email protected]. This would be simple to do in a JSP file, but requirements dictate that the files will be created by people who know basic HTML, but not JSP. Simple text-tags like this should be easy enough for me to explain to them, however. I have the code set up to do resolutions like that for strings, but can anyone think of a way to do it across files? I don't actually need to modify the file on disk - just load the content, modify it, and output it w/in the containing JSP file. I've been playing around with trying to load the files into strings via the apache readFileToString, but I can't figure out how to load files from a specific folder within the webapp's content directory without hardcoding it in and having to worry about it breaking if I deploy to a different system in the future.

  • Skinning WinAPI Controls

    - by Brad
    If you've ever seen an application in the Adobe Creative Suite 5 (CS5), you may have noticed that it doesn't look like the native Windows GUI.. They have modified it to have a different look to it. Where would someone begin to make an application that has a custom skin? CS5 uses the Adobe Source library for it's widget/control management, so I tried downloading and compiling the Adobe Source Library to see if I could make a nice skinned app like Photoshop CS5, but after finally getting it to compile and tested it, I realized the library was only for managing widgets and not skinning the GUI, like CS5 has. Where would I begin to make a nice skinned program like Adobe Cs5 applications? Can anyone point me in the right direction? Do I simply use the WM_PAINT Message from WinAPI and render my own widgets using openGL or something?

  • asp.net server controls

    - by Richard Friend
    Okay i have a custom server control that has some autocomplete settings, i have this as follows and it works fine. /// <summary> /// Auto complete settings /// </summary> [System.ComponentModel.DesignerSerializationVisibility (System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty), Category("Data"), Description("Auto complete settings"), NotifyParentProperty(true)] public AutoCompleteLookupSettings AutoComplete { private set; get; } I also have a ParameterCollection that is really related to the auto complete settings, currently this collection resides off the control itself like so : /// <summary> /// Parameters for any data lookups /// </summary> [System.ComponentModel.DesignerSerializationVisibility(System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty)] public ParameterCollection Parameters { get; set; } What i would like to do is move the parameter collection inside of the AutoCompleteSettings as it really relates to my autocomplete, i have tried this but to no avail.. I would like to move from <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" /> <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </cc1:TextField> To <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" > <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </AutoComplete> </cc1:TextField>
