  • Webbrowser javascript errors

    - by Gaby
    HI, I use a WebBrowser control to navigate to a html page which contains JavaScript. When I open this page in the IE browser no JavaScript error is shown and the page is displayed and functions perfectly. But when navigating to the same page with the WebBrowser control, a pop-up appears to inform about a Script error. I have tried to suppress the script error with the ScriptErrorsSuppressed property but now another pop-up comes up with the title "Visual Studio Just-In-Time Debugger" and proposes to debug. How can i disable all the errors?

  • Make an ActiveX control work without a form?

    - by Earlz
    We are using Topaz Signature pads. They provide their APIs in the from of an ActiveX control which is to be put on a Winform control. Well, the way our project will work we do not want to have a form(at least not visible). We just want for the signature ActiveX control to get an image in the background. static AxSigPlus sig = new AxSIGPLUSLib.AxSigPlus(); public static void Begin() { ((System.ComponentModel.ISupportInitialize)(sig)).BeginInit(); sig.Name = "sig"; sig.Location = new System.Drawing.Point(0, 0); sig.Size = new System.Drawing.Size(0, 0); sig.Enabled = true; sig.TabletState = 1; //error here sig.SigCompressionMode = 0; } Ok so I get an error at the marked line. The exception is Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown. What do I do to solve this problem? Would it just be easier to create a new hidden form and put the control on it so it's invisible?

  • Logging erros in SqlLite database from C# Windows Forms Application

    - by Ismail S
    I'm developing a win app in C# which communicates to a WCF Service. I want to log exceptions that are thrown on client to be logged in Sql Lite Database (Win app is using Sql Lite database for storing data locally). And then later it should be sent to the wcf service when required so that it can be useful for support/analysis/application improvement. I want a method which can be directly called in every catch block simply by LogHelper.Log(ex). I would like to know if anyone has done it through Enterprise library or used any good practice for such situation?

  • How to draw onto a PictureBox image when control resizes?

    - by Sam Mackrill
    I am using the pictureBox_Paint event to try and draw an overlay onto the image in a PictureBox. This is working fine until I resize the PictureBox (set to use SizeMode.Zoom), when I do this the overlay graphic is drawn off position by the margin between the image and the edge of the PictureBox. I guess I need to use the ImageRectangle somehow but this is not public.

  • Get aspect ratio of a monitor

    - by Alexander Stalt
    I want to get aspect ratio of a monitor as two digits : width and height. For example 4 and 3, 5 and 4, 16 and 9. I wrote some code for that task. Maybe it is any easier way to do that ? For example, some library function =\ /// <summary> /// Aspect ratio. /// </summary> public struct AspectRatio { int _height; /// <summary> /// Height. /// </summary> public int Height { get { return _height; } } int _width; /// <summary> /// Width. /// </summary> public int Width { get { return _width; } } /// <summary> /// Ctor. /// </summary> /// <param name="height">Height of aspect ratio.</param> /// <param name="width">Width of aspect ratio.</param> public AspectRatio(int height, int width) { _height = height; _width = width; } } public sealed class Aux { /// <summary> /// Get aspect ratio. /// </summary> /// <returns>Aspect ratio.</returns> public static AspectRatio GetAspectRatio() { int deskHeight = Screen.PrimaryScreen.Bounds.Height; int deskWidth = Screen.PrimaryScreen.Bounds.Width; int gcd = GCD(deskWidth, deskHeight); return new AspectRatio(deskHeight / gcd, deskWidth / gcd); } /// <summary> /// Greatest Common Denominator (GCD). Euclidean algorithm. /// </summary> /// <param name="a">Width.</param> /// <param name="b">Height.</param> /// <returns>GCD.</returns> static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } }

  • Winform radiobutton data binding

    - by Rajarshi
    I am following the "Presentation Model" design pattern suggested by Martin Fowler for my GUI architecture in a Windows Forms project. "The essence of a Presentation Model is of a fully self-contained class that represents all the data and behavior of the UI window, but without any of the controls used to render that UI on the screen. A view then simply projects the state of the presentation model onto the glass...." - Martin Fowler Read more about this pattern at www.martinfowler.com/eaaDev/PresentationModel.html I am finding the concept very fluid and easy to understand except this one issue of data binding RadioButtons to properties on the Data/Domain object. Suposing I have a Windows Form with 3 radio buttons to depict some "Mode" options as - Auto Manual Import How can I use boolean properties on Data/Domain Objects to DataBind to these buttons? I have tried many ways but to no avail. For example I would like to code like - rbtnAutoMode.DataBindings.Add("Text", myBusinessObject, "IsAutoMode"); rbtnManualMode.DataBindings.Add("Text", myBusinessObject, "IsManualMode"); rbtnImportMode.DataBindings.Add("Text", myBusinessObject, "IsImportMode"); There should be a fourth property like "SelectedMode" on the data/domain object which at the end should depict a single value like "SelectedMode = Auto". I am trying to update this property when any of the "IsAutoMode", "IsManualMode" or "IsImportMode" is changed, e.g. through the property setters. I have INotifyPropertyChanged implemented on my data/domain object so, updating any data/domain object property automatically updates my UI controls, that's not an issue. There is a good example of binding 2 radio buttons here - http://stackoverflow.com/questions/344964/how-do-i-use-databinding-with-windows-forms-radio-buttons but I am missing the link while implementing the same with 3 buttons. I am having very erratic behaviors for the Radio Buttons. I hope I was able to explain reasonably. I am actually in a hurry and could not put a detailed code on post, but any help in this regard is appreciated. There is a simple solution to this issue by exposing a method like - public void SetMode(Modes mode) { this._selectedMode = mode; } which could be called from the "CheckedChanged" event of the Radio Buttons from the UI and would perfectly set the "SelectedMode" on the business object, but I need to stretch the limits to verify whether this can be done by DataBinding.

  • Keep Window Inactive In Appearance Even When Activated

    - by Zach Johnson
    Is there a way to keep a window inactive looking, even if it contains focus? I have two forms (A and B). After the user interacts with A, I transfer focus back to B. The result of the focus transfers (the user clicking on the A, then focus being transferred back to B) is that form A blinks from active to inactive. This looks ugly (especially on Vista where A momentarily gets a bigger shadow). How can I make A stay inactive looking so this blinking will not happen?

  • How do I load SciLexer.dll in Visual Studio 2008 Designer, on Windows 7 64-bit?

    - by Filini
    We develop a WinForm application using Scintilla.NET (1.7) component, which uses SciLexer.dll (unamnaged). At run-time, we distribute both 32bit and 64bit SciLexer.dll, and we load the correct one when the application starts (everything works fine). On our new development environments (Windows 7 64-bit), all our solutions build and run just fine, but the WinForm visual designer does not load our forms/controls which use Scintilla.NET, because it cannot load the correct SciLexer.dll: Window class name is not valid. at System.Windows.Forms.NativeWindow.WindowClass.RegisterClass() at System.Windows.Forms.NativeWindow.WindowClass.Create(String className, Int32 classStyle) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg, IntPtr wParam, IntPtr lParam) at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg) at Scintilla.ScintillaControl.get_CodePage() at Scintilla.ScintillaControl..ctor(String sciLexerDllName) at Scintilla.ScintillaControl..ctor() Where does Visual Studio 2008 look for unmanaged libraries? I tried putting the 64-bit SciLexer.dll in SysWOW64, in the folder where ScintillaNET.dll is referenced, adding a folder in PATH system variable, adding a folder reference in the project, but I keep getting this error. Any help is appreciated.

  • Scrolling textboxes programmatically using WndProc messages.

    - by Hannes Nel
    Hi, I'm trying to scroll a textbox using the form's WndProc method. The code I've come up with so far, after scouring the internet, looks like this: private void ScrollTextBox() { scrollMessage = Message.Create(TabContents.Handle, 0x00B6, new IntPtr(0x0003), new IntPtr(0x0000)); this.WndProc(ref scrollMessage); } where TabContents is a TextBox. For some reason, nothing happens when i call this method. I'd like to know why. I realise that i can accomplish the same with the MoveToCaret method, but I'm curious why this is not working.

  • aspNetCompatibility WCF and WinForm

    - by user190084
    I would like to use Windows Forms with a WCF service and leverage the pre-built authentication of asp.net by using aspNetCompatibilityEnabled = true in the WCF service. Is there any module or pre-built assemblies that can add ASP.NET functionality to a Windows Forms application? As far as I understand, this functionality isn't built into Windows Forms and can't be leveraged.

  • How to parse date from string ?

    - by Harikrishna
    I want to parse the date from the string where date formate can be any of different format. Now to match date we can use DateTime.TryParseExact and we can define format as we needed and date will be matched for any different format. string[] formats = {"MMM dd yyyy"}; DateTime dateValue; string dateString = "May 26 2008"; if (DateTime.TryParseExact(dateString, formats, new CultureInfo("en-US"), DateTimeStyles.None, out dateValue)) MessageBox.Show(dateValue.ToString()); This matches with date.But this is not working for parse the date from the string that is it does not matched with the date which is in some string. Like if the date is "May 26 2008" then we can define format "MMM dd yyyy" and date will be matched. But if date is in some string like "Abc May 26 2008" then date will not be matched.So for that can we use regular expression here ? If yes how ?

  • How can I provide a different rendering target to Direct2D?

    - by fingerprint211b
    I'm using Direct2D in C# to render a small gui framework for my research project. I'm not very used to working on Windows or with DirectX. I'm using a Windows Forms control to create a render target, and msdn warns that since it uses BindDC, a the larger the rendering target, the worse the performance will be (which turned out to be a dramatic difference, when I maximize the window, I get around 15 fps). What would be a better way to create a render target for Direct2D? Is there a way to create a window and render directly to it, instead of rendering to a control's buffer first, and then rendering that? If so, how? Sorry if my English sucks, not my native language.

  • C# How to redirect assembly loading using application config file

    - by Adi barda
    Hi Guys, I have an assembly with few versions registered in the GAC. Now, I want one of my clients which uses this assembly (version 1.3) to point to the newest version (1.4) without opening the source and recompiling the client. I saw an article demonstrating a technique for doing so using the application config file (winform application) here is the config file content : <?xml version="1.0" encoding="utf-8" ?> <configuration xmlns:asm="urn:schemas-microsoft-com:asm.v1"> <runtime> <asm:assemblyBinding> as you can see, there is a binding redirect from version 1.3.0.0 to 1.4.0.0 for assembly named MyFacade. Now, there's only a Minor issue with this approach. It doesn't work :) I'm sure it's something with my code. Any suggestions? Thanks, Adi Barda
