  • string <-> int/float conversion pain in .net winform

    - by Benny
    the Text property of control on winform is always string type, so if i wanna expose property of other type for custom control, i have to do the conversion as following, if i have dozens of properties to expose, it will be such pain for me. public int ImageGroupLength { get { return int.Parse(this.imageGroupLength.Text); } set { this.imageGroupLength.Text = value.ToString(); } } so, is there any elegant way to do the conversion?

  • WebBrowser control not navigating to links to "file://" protocol URIs

    - by Nick Butler
    I am setting the DocumentText property to an HTML string that contains links like: <a href="file:///D:/dir/file.html">NewPage</a> The links are shown properly in the WebBrowser, but nothing happens when I click them. The Navigating, Navigated and DocumentComplete events do not fire - nothing seems to happen at all. AllowNavigation is true and other links using HTTP are working. Any ideas please? Nick

    - by Luiscencio
    so I fill my DGV with some data and set some columns invisible: var part = inventory.espiromex_product.Where(p => p.descriptionsmall == cmbMainP.Text).First().partnumberp; dtgAssy.DataSource = inventory.espiromex_productsub.Where(p => p.partnumberp == part); dtgAssy.Columns["idproductsub"].Visible = false; dtgAssy.Columns["partnumberp"].Visible = false; dtgAssy.Columns["partnumbersubp"].Visible = true; dtgAssy.Columns["quantity"].Visible = true; dtgAssy.Columns["comments"].Visible = true; dtgAssy.Columns["assemblyno"].Visible = false; dtgAssy.Columns["assemblynodesc"].Visible = false; dtgAssy.Columns["uomid"].Visible = true; dtgAssy.Columns["subassemblylevelnumber"].Visible = false; dtgAssy.Columns["scrappercent"].Visible = true; this is just fine but columns are sorted Alphabetically, How can I reorder columns programmatically? note that inventory is an Entitie and I am using Linq to Entities.

  • One config file for multiple environments

    - by ho
    I'm currently working with systems that has quite a lot of configuration settings that are environment specific (Dev, UAT, Production). Does anyone have any suggestions for minimizing the changes needed to the config file when moving between environments as well as minimizing the duplication of data in the config file? It's mostly Application settings rather than User settings. The way I'm doing it at the moment is something similar to this: <DevConnectionString>xyz</DevConnectionString> <DevInboundPath>xyz</DevInboundPath> <DevProcessedPath>xyz</DevProcessedPath> <UatConnectionString>xyz</UatConnectionString> <UatInboundPath>xyz</UatInboundPath> <UatProcessedPath>xyz</UatProcessedPath> ... <Environment>Dev</Environment> And then I have a class that reads in the Environment setting via the My.Settings class (it's VB project) and then uses that to decide what other settings to retrieve. This leads to too much duplication though so I'm not sure if it's worth it.

  • NotifyIcon behaviour on Windows 7 with MouseClick, MouseDoubleClick events

    - by binball
    I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :)

  • Strongly Typed Controls in .NET

    - by Tigraine
    I am working on a Windows Forms app for quite some time now, and I really find myself doing more typecasts in the GUI code than I ever did in my underlying business code. What I mean becomes apparent if you watch the ComboBox control that accepts some vague "object" as it's item. Then you go off and may display some DisplayMember and a ValueMember and so on. If I want to retrieve that value later I need to typecast my object back to what it was. Like with strings getting the value takes string value = (string)combobox1.SelectedItem; Since there are generics in the Framework for quite some time now, I still wonder why in the Hell not one control from the standard toolbox is generic. I also find myself using the .Tag property on ListViewItems all the time to keep the displayed domain object. But everytime I need to access that object I then need another typecast. Why cant I just create a ComboBox or ListView with items of type ListViewItem Am I missing something here or is this just another example of not perfectly well thought through controls?

  • Painting to Form then to Printer

    - by jp2code
    I often find myself needing to create custom reports that do NOT work with Crystal Reports or Report Viewer. Often, I hack a DataTable together and dumping that into a DataGridView control. It is never pretty, and printing is difficult. What I need is a class that I can call using the OnPaint event, but I've never sat down and written all of the Pen and Brush commands until now. Painting to the screen and painting to a printer both use the Graphics object, so I want to build a class that I'd pass in the Graphics object, my window bounds (a Rectangle), and some data (in the form of an instance of my class) that I'd use to paint a form or a sheet of paper. That sounds like a great concept! Surely, someone has done something like this before. Does anyone know of a book, a website tutorial, or video that goes into this? If someone wants to write all that out for me here, more power to you - but I'd think that would be too much work.

  • How to report DataContext.SubmitChanges() progress with LINQ2SQL

    - by kzen
    If there is a foreach loop that contains DataContext.Customer.InsertOnSubmit(cust) for example: foreach (Object obj in collection) { Customer cust = new Customer { Id = obj.Id, Name = obj.Name ... }; DataContext.Customer.InsertOnSubmit(cust); } And outside of the loop there is a call to: DataContext.SubmittChanges(); Is there a way to obtain the SubmittChanges progress in order to report the progress back to the user (or a different approach without moving the SubmittChanges into the loop)?

  • Web browser control: Detecting changes in form content

    - by Khou
    A form contains many elements, such as labels, Textbox, radio options box etc How do you detect the user has changed a textbox input value, or has choosen a radio option within the content of a web browser control? (not the winform itself). Do you handle a winform event for when the mouse clicked or keyboard keys pressed? or is there a better way to detect changes in the web browser content?

  • Quicken like Windows Forms application

    - by WinFXGuy
    Hi All, I need to build a quicken like application, where data needs to be secure. I don't see any database being used by Quicken. I could use XML, MDF or Access database, but data is not secure in the tables. What is the best option? How does Quicken handle it? My application may also have document attachments as well. The functionality of this application is similar to quicken but not an accounting/financial in functionality. Thanks a bunch!

  • Simple Windows.Forms binding is failing using framework 4.0.

    - by jyoung
    This works under the .net framework 3.5 client. This fails under the .net framework 4.0 client. Was I doing something that was illegal under 3.5 but just happened to work, or is this a bug? Note that in my project 'PropInt' does not raise change events so using ctx[obj1.PropObj2, "PropInt"] is not an option. public class Obj1 { public Obj2 PropObj2 { get; set; } public Obj1() { PropObj2 = new Obj2(); } } public class Obj2 { public int PropInt { get; set; } } static class Program { [STAThread] static void Main() { var ctx = new BindingContext(); var obj1 = new Obj1(); var x1 = ctx[obj1, "PropObj2.PropInt"]; } }

  • Databinding Textbox to Form.Text (title)

    - by MysticEarth
    I'm trying to bind a Textbox.Text to Form.Text (which sets the title of the form). The binding itself works. But, the title isn't updated until I move the entire form. How can I achieve Form.Text being updated without moving the form? I'd like Form.Text being updated directly when I type something in the Textbox. Edit; I set the title of the Form in a TextChanged event which is fired by a ToolStripTextbox: public partial class ProjectForm : Form { public ProjectForm() { // my code contains all sorts of code here, // but nothing that has something to do with the text. } } private void projectName_TextChanged_1(object sender, EventArgs e) { this.Text = projectName.TextBox.Text; } And the Databinding version: public partial class ProjectForm : Form { public ProjectForm() { this.projectName.TextBox.DataBindings.Add("Text", this, "Text", true, DataSourceUpdateMode.OnValidation); } } Edit 2: I see I forgot to mention something. Don't know if it adds anything, but my apllication is a MDI application. The part of the title that changes is: ApplicationName [THIS CHANGES, BUT ONLY AFTER MOVING/RESIZING]

  • How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

    - by peace
    I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

  • Mouse Capture and Selection

    - by Tommy
    I have a control, that moves around alot of different controls inside of it in the form of a grid. So basically, none of the container control is shown at any point. But i do have capture of all the mousedown and mousemove events of the controls inside. What id like to do, is create an effect alot like the desktop of a windows computer, where you can drag, and every control that is inside of the mouse's drag will be thrown in a list, and when the mouse is released i can perform an action on all the selected items. Is this possible?

  • Is it possible to avoid Focus on SplitContainer?

    - by Filini
    The WinForm SplitContainer gets the focus when it's dragged or clicked, while the Splitter does not. The side-effect of this, is that dragging a SplitContainer bar fires Leave/Validate on other controls, and I need to avoid this. I already tried setting TabStop and CausesValidation to False, but with no success. Is there a way to stop the SplitContainer from getting focused? (not a big deal, I can still use the old Splitter, but I lose some nice VS properties...)
