    - Creating a Windows App version of a Web App I have a fully functional web app that I created in Visual Studio 2003. I've even managed to translate it to a functional working 2005 version. What are the best steps to creating a Windows based form version in a manner that I can preserve a lot of the routines that I have written? For example, I have a connection string in a WebConfig file that I refer to in my Data Access Layer. I didn't use the graphical objects to do this, I wrote most of the code and I would like to use this setup to take a lot of business logic along for the ride: For example, this routine fils a DataGrid on a Patient Screen with Lab results Public Shared Function GetLabs (ByVal lMRN as integer) as dataset Dim conMembers as SqlConnection = GetMembershipConnection() Dim strLabsSQL as string strLabSQL = "SELECT Proc_Name as [Lab Procedure], Comp_Name " _ & "as Component, Result " _ & "FROM tbl_Lab " _ & "WHERE MRN = @MRN " _ & "ORDER BY Result_Date desc" Dim cmdGetLab as new sqlCommand(strLabSQL, conMembers) cmdGetLab.CommandType = CommandType.text Dim daLab as New SqlDataAdapter daLab.SelectCommand = cmdGetLab Return dsLab End Function '============================= I know there are new graphical ways to do this, but to save time, I would like to use the types of tools I have already created, and not spend time trying to learn about a more simple redesign using the new graphical tools. Unless their is a simple way of illustrating how I could change the above sample. The majority of my tools are setup this way. We are trying to quickly migrate into a stand-alone desktop version which connects to a subscribed replicated SQL Express version. A replacement for my connection reference in WebConfig setup using the AppConfig tool would be very valuable. Thanks! Tag: Refresh Binding Tag: 103827

    - Context menus on TextBox and RichTextBox Hi, I am using a RichTextBox and I would like to have the standard context menu (RightClick menu) that the standard TextBox control has (i.e. if you use TextBox instead of RichTextBox, there is a standard context menu with Cut, Copy, Paste and few other selections right out of the box, you don't need to do anything). However, this is not available (at least not right out of the box) for the RichTextBox. I tried to find a property or a method to enable this but could not find anything - it looks like I need to implement the context menu. Not that it is a big deal, but all I need is exactly what's in the TextBox context menu, and I wonder if there is an easier way to enable it. Thanks, Ivan Tag: Refresh Binding Tag: 103825

    - How to host CHM help viewer in an MDI child form? I am writing a Windows Forms application using VS.NET 2003 and C#. The application uses the Multi-Document Interface (MDI) style. Our customer education team requires that the application display context-sensitive help using the common CHM file format. We are currently using P/Invoke as follows to display the help file: [DllImport( "HHCtrl.ocx" )] public extern static int HtmlHelp( int hwnd, string pszFile, int cmd, int data ); protected const int HH_HELP_CONTEXT = 0x000F; virtual protected int DisplayHelp( int helpID, string fileName, string helpName ) { // Open the HelpViewer window. int res = HelpControlBase.HtmlHelp( 0, fileName, HH_HELP_CONTEXT, helpID ); return res; } This launches a new form in a child process. We now need to have the CHM help content be hosted in an MDI child form so that the child form can be managed like all of the other child forms. I have searched without success for information on how to do this. How can I display the CHM help content in an MDI child form? Is there a .NET solution for this? Thanks, Dave -- Dave Leach Agilent Technologies, Inc. Tag: Refresh Binding Tag: 103821

    - TextBox OnKeyUp/Down, ProcessCmdKey acting up... a lot I'm writing a hotkey selection control, which inherits from a TextBox. It seemed to work fine for a while, but I ran into a huge bug today. The KeyCode/KeyData values are completely whack, I get the same results with KeyUp/KeyDown event handlers and overriding ProcessCmdKey(). Lets say I press "7" (not the numpad 7), and examine the KeyCode/KeyData values on the first line of ProcessCmdKey. I get this... keyData = LButton | RButton | MButton | ShiftKey | Space That's when I press and quickly release a single "7". Numpad 7 gives 0x67, looks sensible... The caret key, next to return (on a Swedish keyboard) gives: RButton | Back | ShiftKey | Space | F17 What the hell is going on? Anybody with a clue? Some keystrokes (such as most letters) work just fine. Thanks in advance /Thomas Tag: Refresh Binding Tag: 103820

    - Which is the sequence of events when using ShowDialog()? Hi all, I'm having troubles with a Symbol 9000 device (Compact Framework v 1.1) when activating the barcode scanner from a window. The problem is related to the Activated event of the form which carries the task of the initializing the scanner. It looks like this event is not called after the creation of one of the forms. Let me describe shortly the sequence of form creation. The app first call a browsing form by using ShowDialog(). This browsing form (modal dialog) calls a data input form that uses the scanner device using ShowDialog(). It works as expected. On the Activated event it captures the scanning device and on Deactivate releases it. This forms is also a modal dialog. From this data input I call a third data input form also by using ShowDialog(). Note it is the third on the "stack" of called modal dialogs. The Deactivate event is called for the second form and the scanner is released, but the Activated event is not called for this third form then the scanner is not activated. To get the Activated event called I should make a trick: The three modal dialogs are represented on the taskbar as buttons. I can click the button of the second form. It is displayed but is blocked for input. But in this click the Deactivate event is called for the third form and the Activated is called for the second. Then I click the button on the taskbar for the third form and voila! the Activated event is called for the first time for the third form, resulting in the scanner device being activated. I should note that the handlers for these events are registered in the Load event handler. The Load event handler is registered on InitializeComponent as normally it is created from the Visual Studio 2005. I fear the Activated event is called before the Load when the handler is not registered yet. What can be wrong? Which is the sequence of events when using ShowDialog()? Any hint is welcomed Thanks in advance Sammy Tag: Refresh Binding Tag: 103817

    - Finding text from a single cell in a datagridview Hi, I have a datagrid view that I have manually bound with a dataset. It has a column displayed as checkboxes, what I want to do is update the database when a checkbox is checked. To do this I need to find a value at cloumn index = 0 that corresponds to the row in which the checkbox has just been checked. Here is what I have: private void dgErrorLog_CurrentCellDirtyStateChanged(object sender, EventArgs e) { int row = dg.CurrentCell.RowIndex; int col = 0; string loc = // Text in cell (0, row); } So when the checkbox value changes, i find the row index of it. The problem is now that i don't know how to set the text in cell (0, row) to a useable string. Any ideas? Thanks. Tag: Refresh Binding Tag: 103814

The problem was not related to Debug vs Release mode, order of form painting events, in process vs out of process COM servers, BeginUpdate()/EndUpdate, SuspendLayout()/ResumeLayout(), SuspendBinding()/ResumeBinding() or any other "usual suspect". It was purely a problem within the WinForms engine when it comes to painting forms. I proved this by creating a simple form and dragging about 20 controls onto it. Display this form via a COM interface and the painting speed is terrible (checked list boxes are particularly bad), run it by double clicking the EXE from within Windows Explorer and the painting speed was great. So what's the difference? It turns out that the problem is related to these 2 magic lines that VS2005 puts at the beginning of the Main method in every Windows Forms application: Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); You know, the 2 lines that you mentally tune out because they are always there and you never need to edit them and they run first before anything happens because Main is the entry point for your application... However, if you are allowing callers to display forms via a COM interface then you have multiple potential entry points to your assembly, and Main is actually unlikely to be the first method to run. For example, here is a COM interface in a test app I wrote: [ComVisible(true)] [Guid("33F6DDA9-0D4D-4276-AC8D-C66E315649F2")] [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] public interface IShowForms { void ShowForm(); } [Guid("3649EC0C-8F49-4844-B2F0-EF154E2D10AF")] [ClassInterface(ClassInterfaceType.None)] [ProgId("COM.ShowForms")] [ComVisible(true)] public class ShowForms : IShowForms { public void ShowForm() { using (Forms.frm1 f = new Forms.frm1()) { f.ShowDialog(); } } } You can instantiate and run this from VBA using the following: Dim f As COM.IShowForms Set f = New COM.ShowForms f.ShowForm If you do this, then those magic 2 lines don't get called and the painting performance is pathetic. So to solve the slow painting problem we need to ensure those 2 lines are run (the WinForms engine also requires that the 2 lines are run before any forms are displayed and that they are only called once). My quick and dirty solution is to add a static variable and method to the Program class: private static bool m_VisualStylesHaveBeenSet; public static void SetVisualStyles() { if (!m_VisualStylesHaveBeenSet) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); m_VisualStylesHaveBeenSet = true; } } Then adjust Main to call this method, and ensure that the constructor of every class which is exposed via COM also calls it: static void Main() { SetReferenceToConfigFile(); SetVisualStyles(); Application.Run(new frmMain()); } public ShowForms() { Program.SetVisualStyles(); } This is a tolerable solution at the moment because I only have about 5 COM-exposed classes, but a better solution might be to try and call it when the assembly is loaded. By the way, it's actually the call to EnableVisualStyles() which is the one which gives the performance boost, the other line doesn't seem to make any difference. I have had a look at the code for the EnableVisualStyles() method in Reflector, and it doesn't seem to do much so the reason for the poor performance is still unknown to me. I suspect it is hidden deep in the WinForms engine, and may be operating system related (I am on XP Pro SP2). Happy interopping! -- Phil Tag: Refresh Binding Tag: 103813

Subsequently, perhaps I or someone else could do the same for WebForms. For now, here are a few things I thought of (and I could be in error; that's the point your help). 1. System tray 2.

    - ListView sort only sorts on paint? Has anyone notices this behavior? I have a composite control that contains a listview. I've created my own listviewsorter class that works just fine. As items get added (in this case - a very small #, less than 40), I repaint all items background to white, sort, and perform a colorization. The code was supposed to colorize some things in an alternating pattern, but i noticed sometimes it wasn't alternating. What I found was although my colorization colored the correct items - the sort wasn't happening until the parent that housed the composite control got redrawn!!! I tried a Refresh, an Update, a ResumeLayout, RedrawItems, etc. Nothing got this to work with the listview. I did code around it myself with a sortedList, but I find it odd that when I call ListView.Sort it just seems to queue up the sort for the next paint operation. Am I mistaken? Does anyone know how this really works? Tag: Refresh Binding Tag: 103780

Click anywhere on the Excel spreadsheet in the DSOFramer control. 4. The menu DOES NOT collapse. I have tried a number of combinations: .NET 1.1, third-party menu controls. Nothing works. The only control combination that does work is using Visual Studio 2003 and using the standard MainMenu control provided by Visual Studio. This seems to work okay HOWEVER, this control is very bland (does not allow for command icons) and is not useful for my project. In order to debug the problem I have also tried the following: 1. Capture EVERY event exposed by the DSOFramer control. No events are fired (such as Leave and Enter) when I click on and off of the hosted spreadsheet. 2. Ran the program using Spy to see what Windows messages were being sent. It appears WM_NOTIFYPARENT is sent but apparently .NET 2.0 ignores it (as does .NET 1.1). I'm no expert on Windows messages so perhaps I'm missing something rather than .NET! Any and all help is much appreciated. Tag: Refresh Binding Tag: 103753

    - adding images to grid columns? .net 1.1 I have a windows forms .net 1.1 question: I tried adding an image (a picturebox) to a column in my grid, but haven't been able to do it adequately. The pictures are there, but they don't seem to be visible until I click on a cell and then the picture is visible. Not sure what's going on. Can you tell from the following code, or is there a better way: Sub DoAssessmentGrid() If bus.AssessmentList(ActionRequested.CaseNumber) Then Dim ts As DataGridTableStyle ts = dgAssessments.TableStyles(0) ts.MappingName = "ClientAssessments" Dim booleanColumn As DataGridBoolColumn booleanColumn = ts.GridColumnStyles.Item("CompleteBool") booleanColumn.TrueValue = True booleanColumn.FalseValue = False booleanColumn.NullValue = Convert.DBNull Try Dim executing_assembly As System.Reflection.Assembly = Me.GetType.Assembly.GetEntryAssembly() Dim my_namespace As String = executing_assembly.GetName().Name.ToString() If Not ts.GridColumnStyles.Item("Action") Is Nothing Then ActionColumn = CType(ts.GridColumnStyles.Item("Action"), DataGridTextBoxColumn) ActionColumn.Alignment = HorizontalAlignment.Center imgEdit = New PictureBox imgExport = New PictureBox Dim curDir As String = Environment.CurrentDirectory() imgEdit.Image = Image.FromFile("D:\OKDHS\AGING\ELDERS\ELDERSRemote\images\Edit.gif") imgEdit.Cursor = Cursors.Arrow imgEdit.SendToBack() imgExport.Image = Image.FromFile("D:\OKDHS\AGING\ELDERS\ELDERSRemote\images\btnExport.gif") imgExport.Cursor = Cursors.Arrow imgExport.SendToBack() ActionColumn.TextBox.Controls.Add(imgEdit) imgEdit.BringToFront() 'ActionColumn.Width = 65 'ActionColumn.TextBox.Controls.Add(imgExport) End If Catch ex As System.IO.FileNotFoundException SystemMessage.Tell("Couldn't find one of the image files for the grid") Catch ex As Exception End Try dgAssessments.DataSource = bus.ObjectDataSet dgAssessments.DataMember = ts.MappingName End If End Sub Tag: Refresh Binding Tag: 103740

    - Custom title bar drawing Hello, I'm trying to make a skinned application, so i'm overriding the paint methods of the controls. Concerning the painting of the form itself, it seems that there are 2 options: - Making the form borderless (FormBorderStyle to None), and building our own custom window title bar, but just think that this needs some useless work as we have to rewrite some window functions (move, resize, ...). Moreover, when maximizing the window, it makes it fullscreen. - This lead me to the second option which was to use the non client area painting by catching the WM_NCPAINT message in the WndProc method. With the help of some Win32 functions, i paint on the form (FormBorderStyle to Sizable) but something weird happens, the system buttons on the title bar redraw themselves, for example, when i move the mouse over the window. So they appear on the custom painting... Does someone have an idea of what happens with the maximize/minimize/close buttons and/or have a workaround for the second option ? Cannot find which message makes the buttons to be repainted. Or is the first option the best solution to make a skinned application ? Thanks for your help! Valerie Tag: Refresh Binding Tag: 103731

    - ToolStrip menu and MDI application Hi all Using VS2005 and .Net 2.0. I have a MDI parent form, and MDI children. What I would like to do is similar to merging menu's. I found you can define the menus on the child, specify a merge index and have the menu merge nicely with the MDI parents menu. Ideas? Thanks Andy Tag: Refresh Binding Tag: 103714

    - Keeping ToolStrip inside the same ToolStripContainer I would like to use multiple ToolTripContainers in my Form. I would like the ToolStrips in each ToolStripContainer to be freely movable within its container, but I would like to enforce a rule such that ToolStrips cannot be dragged from one ToolStripContainer to another. I am encapsulating each ToolStripContainer within a user control for several reasons, code reusability and layout simplicity being the main ones. I was hoping to simply implement a QueryContinueDrag handler in my UserControl but it does not seem to be getting called as I drag the ToolStrip around the screen. I'm using VS2005, .NET 2.0. I'm a veteran MFC programmer, been working with .NET for a couple of months - this is the first thing I've come up against where I wasn't able to find a solution with a little elbow grease!

    - ListView Custom Sorting and repositioning later I have a ListView with a custom ListViewItemSorter assigned. After I add all the items I assign the sorter and everything is sorted fine. This works the way I want. Now I want the user to be able to move items within the ListView but they're always resorted. If I try and set ListView.ListViewItemSorter = null then the items are no longer sorted in the original order. Any ideas how to work around this? -Joe Tag: Refresh Binding Tag: 103706

Hi,

I have a Typed DataSet that is bind to some winform controls. TextBox,
Labelx etc....
At some point, my dataSet values are updated being the scene. The
probleme is that my binded controls are not updated automatically when
DataSource is updated.
What I have to do to force the rebind of my controls ?

Hi Etienne,

Normally, using the Control.DataBindings instance property will do the trick. Just make sure that each control is bound to the same
object and that you are updating the same object to which the controls are bound.

Could you post your data-binding code?
