  • Where can I find a nice .NET Tab Control for free?

    - by Nazgulled
    I'm doing this application in C# using the free Krypton Toolkit but the Krypton Navigator is a paid product which is rather expensive for me and this application is being developed on my free time and it will be available to the public for free. So, I'm looking for a free control to integrate better into my Krypton application because the default one doesn't quite fit and it will be different depending on the OS version... Any suggestions? P.S: I know I could owner-draw it but I'm trying not to have that kind of work... I prefer something already done if it exists for free. EDIT: I just found exactly what I wanted: http://www.angelonline.net/CodeSamples/Lib_3.5.0.zip

  • Windows forms application blocks after station lock

    - by Silviu
    We're having a serious issue at work. We've discovered that after the station where the client was running is locked/unlocked the client is blocked. No repaint. So the UI thread is blocked with something. Looking at the callstack of the UI thread (thread 0) using windbg we see that a UserPreferenceChanged event gets raised. It is marshalled through a WindowsFormsSynchronizationContext using it's controlToSend field to the UI. It gets blocked by a call to the marshalling control. The method called is MarshaledInvoke it builds a ThreadMethodEntry entry = new ThreadMethodEntry(caller, method, args, synchronous, executionContext); This entry is supposed to do the magic. The call is a synchronous call and because of that (still in the MarshaledInvoke of the Control class) the wait call is reached: if (!entry.IsCompleted) { this.WaitForWaitHandle(entry.AsyncWaitHandle); } The last thing that i can see on the stack is the WaitOne called on the previously mentioned AsyncWaitHandle. This is very annoying because having just the callstack of the runtime and not one of our methods being invoked we cannot really point to a bug in our code. I might be wrong, but I'm guessing that the marshaling control is not "marshaling" to the ui thread. But another one...i don't really know which one because the other threads are being used by us and are blocked...maybe this is the issue. But none of the other threads are running a message loop. This is very annoying. We had some issues in the past with marshaling controls to the right ui thread. That is because the first form that is constructed is a splash form. Which is not the main form. We used to use the main form to marshal call to the ui thread. But from time to time some calls would go to a non ui thread and some grids would broke with a big red X on them. I fixed this by creating a specific class: public class WindowsFormsSynchronizer { private static readonly WindowsFormsSynchronizationContext = new WindowsFormsSynchronizationContext(); //Methods are following that would build the same interface of the synchronization context. } This class gets build as one of the first objects in the first form being constructed. We've noticed some other strange thing. Looking at the heap there are 7 WindowsFormsSynchronizationContext objects. 6 of these have the same instance of controlToSend, and the other one has some different instance of controlToSend. This last one is the one that should marshal the calls to the UI. I don't have any other idea...maybe some of you guys had this same issue?

  • WinForm PDF viewer with programatic search functionality

    - by Anthony Shaw
    We are currently using PDFTron's PDFView WinForm control to view PDF's in a WinForm application. I can load the file and search the file to highlight a certain text value. We have run into an issue where we have expired our trial license period and do not wish to shell out the $900/seat licensing on 15-20 computers. Does anybody know if the ActiveX Adobe Reader control can support the searching functionality programatically? I've tried that and the FoxIt Reader OCX control and neither seem to have this feature exposed (unless it's hidden really well) Does anybody have any suggestions for other freeware/open source viewers, or less-expensive viewers? TIA!

  • Combine master-detail databinding

    - by clawson
    I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values. How can I combine these values into one data grid? (Preferably without creating a wrapping class) Can I achieve this with LINQ somehow? Your help is greatly appreciated. Thanks P.S. C# or VB examples will do.

  • Save data in bulk.

    - by Muhammad Kashif Nadeem
    I have a window having multiple tabs. Each tab having different grids. I want to save all changes on any tab on any grid in bulk. I mean I have one save button which will save all changes in any grid on any tab. I think DataTables will work fine here. Can you suggest me that it is good to use DataTables to ADD/Edit data and save data in bulk using these DataTables OR is there any better way to achieve this. My DAL is generated from LLBLGen Pro (ORM) but you are open to suggest me a solution. Thanks. Edit: I am using Telerik controls so I can get all data in DataTable like DataTable dtProducts = this.radGridView1.DataSource as DataTable;

  • 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); } }

  • Form for Telerik RadRibbonBar?

    - by Cyclone
    I got the Telerik RadRibbonBar for free with the Express edition of vb a while back, but it did not come with any sort of form. It also, unfortunately, has the control buttons there automatically. How would I create a form which is resizable, and works like a standard winform, but doesn't have the top bar? I tried: FormBorderStyle = Sizable Text = Nothing ControlBox = False Unfortunately, when you maximize the window, it goes in front of the taskbar...and it has an ugly border when it isn't maximized. How can I: Change border color? Make it so it does not go in front of the taskbar? Thanks for the help! I'm surprised there is not some sort of form already made for this.

  • Combobox in bound DataGridView

    - by Dan
    Hi. I've got a DataGridView control which is bound to a database table. I want one of the columns in the gridview to be of combobox type. The combobox should contain a list of hardcoded strings, which is the same for all rows in the datagridview. One of the fields in my database table is an index for this list of hardcoded strings. I've programatically added a new column to the gridview of type "DataGridViewComboBoxColumn", which successfully creates the column with comboboxes in it. However, that's then not bound to the index field in my DB table. The index field in my DB table is actually automatically bound to a column via the DataAdapter::Fill method. I've set this column to hidden, so it's hidden to the user. Obviously just before updating the dataadapter, I can programatically fixup the hidden column in my datatable with the SelectedIndex of my combobox. Just wondering if there's a better way of doing this? Thankyou for any help with this, Dan.

  • How to change which item is “outlined” in a ListBox without changing the selection?

    - by Timwi
    How do you change which item is “outlined” in a ListBox? See the following screenshot for clarification: Background: I want to have a standard multi-select listbox that works normally. Unfortunately, the Windows Forms ListBox (with SelectionMode.MultiExtended) is not fully functional. The missing functionality is that it doesn’t let you select a disjoint set of items by using Ctrl+Arrow keys and Ctrl+Space. (Try it in Windows Explorer to see how it’s supposed to work.) I am trying to subclass ListBox and add this missing functionality. To this end, I intend to respond to Ctrl+Arrow keys in the OnKeyDown protected method, but in order to do so, I need to be able to move the outline without changing the set of selected items. How do I do that?

  • Webbrowser javascript errors

    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?
