    - How to add DeckWorkspace to VS05's General tab? Where is the DeckWorkspace component? I'm trying to get up to speed with CAB and am following the Patterns and Practices example. However, the instructions says to 'Drag a DeckWorkspace from the General table of the Toolbox into each..." but I don't have a DeckWorkspace component in VS05's Toolbox to drag. How do I get the darned thing there? -- Richard Lewis Haggard General: www.Haggard-And-Associates.com Please come visit here for a couple thousand good giggles!: www.haggard-and-associates.com/Humor/humor.htm Tag: Auto Hide AppBar Tag: 111788

    - Question about deployment of a Winforms app on a server (Excuse me if this is a duplicate. My previous post appears to have gotten lost.) I am currently working in at a company with a fairly large intranet (uses Active Directory). One of my co-workers is trying to deploy a Winforms application onto one of the windows servers. The intent is to share the directory and allow multiple persons to run the exe on the one server. What are some of the potential problems? (Just looking for general feedback. I come from a web development background and my winforms skills are a bit rusty. And yes, the possibility of turning it into a web app has been discussed.) Tag: Auto Hide AppBar Tag: 111787

    - Prevent row change Datagridview Hi all, How do I prevent row change in a Datagridview? Is there something like a BeforeCurrentRowChanged with an eventarg that could prevent from changing current row? I'm using datagridview bind with a datatable. (I think old ADO had an event that could achieve this!) TIA, DC Tag: Auto Hide AppBar Tag: 111781

    - Big picture question about the deployment of Winforms exe's I work in a company with a large corporate intranet. Many of the servers are both SQL Server hosts and file servers. For reasons beyond my understanding (i.e. management), it has been proposed that a new Winforms application be deployed by putting it on the same server as the database server it uses. Presumably users would just set up mapping to that server via Windows Explorer and probably set up a shortcut icon on their desktop. (I really haven't given much thought to this sort of a problem, since much of my recent work as been in Webforms.) What would be the drawbacks of this approach, if any?

    - how to raise user events in VS 2005 (COM) sub-Winform, handle in V I am trying to raise a user-defined Event in a VB.NET 2005 COM Class (sub)form and have my calling VB6 form handle it. Code samples follow. In the VS 2005 code two events are coded identically - when they are RAISEd in reaction to a Framework Event they WORK, but when they are RAISEd in response to by user action within the VB.NET 2005 Subform they do NOT: =================================== ' 1. Here are the Events, defined in the same fashion in the VS 2005 (sub)form =================================== #Region "User-Defined Variables" Public Event ExitOBRpayerDialog() Public Event NetworkAvailabilityChanged( _ ByVal IsAvailable As Boolean) =================================== ' 2. Here are the Event Handlers for the Subs that will Raise the Events ' to the calling VB6 form, both added in the VS 2005 (sub)form constructor =================================== #Region " Windows Form Designer generated code " Public Sub New() MyBase.New() 'This call is required by the Windows Form Designer. InitializeComponent() 'Add any initialization after the InitializeComponent() call AddHandler Me.FormClosing, AddressOf frmOBRpayer_FormClosing AddHandler My.Computer.Network.NetworkAvailabilityChanged, _ AddressOf My_NetworkAvailabilityChanged AddHandler btnCustom.Click, AddressOf btnCustom_Click End Sub =================================== 3. Here are the VS 2005 Subs that are supposed to Raise the Events. When the OS raises the My.Computer.Network.NetworkAvailabilityChanged event, both User Events are raised by the first Sub below. They BOTH fire and are handled properly by the VB6 calling form!!! When either of the other two Subs is executed it is because of a Form Event, i.e. a user clicking a button (Form Close in the 2nd sub and btnCustom in the second). In this case, NEITHER User Event that is RAISED gets back to the VB6 program and neither is handled!!! The VB6 code for both Events is similar also, but I include it further below for completeness anyhow. WHY oh WHY cannot I fire my User Events with a form button click? WHY does an Event raised by the OS work and a user action does not??? (BTW, the way the OS fires both events is when I pull the network cable out of my workstation). =================================== Public Sub My_NetworkAvailabilityChanged(ByVal sender As Object, _ ByVal e As _ Microsoft.VisualBasic.Devices.NetworkAvailableEventArgs) RaiseEvent ExitOBRpayerDialog() RaiseEvent NetworkAvailabilityChanged(e.IsNetworkAvailable) Application.DoEvents() End Sub ----------------------------------------------------------------------------- Public Sub frmOBRpayer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Dim crCloseReason As Windows.Forms.CloseReason Dim ev As New Microsoft.VisualBasic.Devices.NetworkAvailableEventArgs(False) Try crCloseReason = CloseReason.UserClosing crCloseReason = e.CloseReason Select Case crCloseReason Case CloseReason.UserClosing PayerCode = "71LA" RaiseEvent ExitOBRpayerDialog() ' DOES NOT FIRE - why oh why? Application.DoEvents() Case Else PayerCode = "OOPS" If OBRMode Then RaiseEvent ExitOBRpayerDialog() ' DOES NOT FIRE - why oh why? Application.DoEvents() Else RaiseEvent ExitOBRpayerDialog() ' DOES NOT FIRE - why oh why? Application.DoEvents() End If End Select Catch ex As Exception If exceptionPolicy.HandleException(ex) Then Me.handle_Ignorable_Exception(ex) Finally Call My_NetworkAvailabilityChanged(Me, ev) ' DOES NOT FIRE even though the Sub is the one that RAISEs bothEvents! End Try End Sub ----------------------------------------------------------------------------- Public Sub btnCustom_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) ' Does a custom form operation. First removes any errors on the form, ' then restores the data at it looked before the last user Save. Dim ev As New Microsoft.VisualBasic.Devices.NetworkAvailableEventArgs(True) Try Call My_NetworkAvailabilityChanged(Me, ev) ' DOES NOT FIRE even though the Sub is the one that RAISEs bothEvents! Catch ex As Exception If exceptionPolicy.HandleException(ex) Then Me.handle_Ignorable_Exception(ex) End Try End Sub =================================== ' 4. Here is the VB6 calling form code for handling the two User-Defined Events =================================== Option Explicit Private WithEvents clsOBRPayer As frmOBRpayer ... Private Sub Form_Load() ' Instantiate the object defined above as "With Events" ' Note that this object is NEVER reset to 'Nothing'. Set clsOBRPayer = New frmOBRpayer ... ' Here is where the .NET (sub) form is actually run Public Sub cmdManipulatePayers_Click() Screen.MousePointer = vbHourglass With clsOBRPayer .Billing_Patient_ID = 902264244 .Admit_ID = 1 .Patient_First_Name = "Silly" .Patient_Last_Name = "Willy" .OBRMode = True .runForm End With Screen.MousePointer = vbDefault End Sub ----------------------------------------------------- ...

    - Using the TextRenderer Class I've been working with the "TextRenderer" class. I'd like to get it to display text in a PictureBox and add an ellipsis if the box is too small for all of the text. I've created a form with a PictureBox (picTest1) that's too small for all of the text and this is the "Paint" event for the PictureBox: Private Sub picTest1_Paint(ByVal sender As Object, _ ByVal e As System.Windows.Forms.PaintEventArgs) _ Handles picTest1.Paint Const MSSG As String = "This is the PictureBox text. " & _ "It is very long in order to test the wrapping and " & _ "ellipse functions of the TextRenderer class." TextRenderer.DrawText(e.Graphics, MSSG, _ Nothing, e.ClipRectangle, Nothing, _ TextFormatFlags.HorizontalCenter _ Or TextFormatFlags.Top _ Or TextFormatFlags.WordBreak _ Or TextFormatFlags.WordEllipsis) End Sub It works fine on a single line, but when I add the "WordBreak" flag, the ellipsis disappear. The documentation says you can't combine the "ExpandTabs" flag with one of the "Ellipsis" flags, but it doesn't say that this won't work with "WordBreak". Am I doing something wrong? Is there any other technique for rendering the text and adding an ellipsis if the PictureBox is too small? Tag: Auto Hide AppBar Tag: 111772

    - grid of user controls Hi Looking for a bit of advice here. I'm building an application that needs to display a grid (days in a year or month along the top and people down the side) in which each cell is a user control. The number of rows and columns are both variable. I've contemplated and partially tried various ways to tackle this, e.g.: - DataGrid (need to define columns, styles? - not got that far) - DataGridView (ditto - better / easier than DataGrid?) - Adding controls to a scrollable panel (possible issues with running out of window handles with large grid) I did also try doing this by rendering a large bitmap - this ran fairly nicely when it worked but I kept getting OutOfMemory exceptions and I would have to sacrifice a lot of flexibility and interactivity. As you can see I have a few ideas and I was wondering if anyone out there had any suggestions, alternatives or hints on what best practice might be with this sort of thing?

    - Usercontrol validating with messagebox and tabcontrol For a Windows forms application I use the following construction. I have a form with a TabControl. On each TabPage there is a custom user control. The custom user control gets some parameters from the form, to set the data of the user control. In the validating event of the custom user control I check or there are any changes made by the user. If so, a message box is shown with the question â??Save changes?â?? The validating event is fired on tab switch and form close, that is what I want. But the problem is, on tab switch the message box is shown, but after that the tabs donâ??t switch any more. Is there a way to achieve this goal, user controls that a self responsible for their data saving? Tag: Auto Hide AppBar Tag: 111741

While these types of exceptions are caught by the CLR, they can still lead to corruption and data loss so if possible the issue causing the exception should be addressed If it happens in the debug, you click the Continue button for couple of times, it can recovered from the exception. Anyone have idea what is going on? Thanks in advance. Tag: Auto Hide AppBar Tag: 111708

    - Displaying new controls and threads. I have a .NET UI threading question. I know the general rule that UI contents can't be changed from another thread. Here's my specific situation. I built a DLL that contains a unified GUI layout for several projects we're working on. The layout is basically a Form with a TableLayoutPanel (1 row, 2 columns), call it myMainTableLayoutPanel. Col0 contains a TreeView that we'll use to display different steps that application takes. The TreeNodes for the tree are provided by the individual groups when they use the DLL. Col1 contains essentially a blank panel where each product group will plug their own content. As far as this main DLL is concerned, accessing the TreeView (giving it the contents, changing color/checkboxes of the nodes) and displaying "something" in the blank panel on Col1, all follow the delegate threading model (use delegates and Invoke() methods). Now we come to the individual groups that are writing what essentially is a plugin for the DLL. lets say I write a plugin that will display calculation of Pi in the blank panel of Col1. To do that, I have created a PiCalculationPane (name it piCalculatorPane) that has some label used to print out how many digits of Pi have been calculated so far. Basically, I am talking about dynamically changing the contents of the pane that is displayed in blank panel. The application that displays the blank panel runs in its own thread. How far do I have to follow the UI threading model? If I want to update the Pi calculation in the piCalculatorPane, do I just call piCalculatorPane.Invoke(delegate fcn) and within fcn update the data, or do I have to chain the Invoke call down to myMainTableLayoutPanel? Sorry for a long and winded question, Thanks, Andrei Tag: Auto Hide AppBar Tag: 111704

    - Seeing the selected node after TreeView expansion Hi there, I have a treeview withmany nodes within it, at many levels. I have writen a function which collapses the list at a certain node level and another function for expanding the list out fully. The problem is that after I expand the list, the end (bottom section) of the expanded list comes into view, resulting in the fact that sometimes the selected node is not visable after expansion. I wish to adjust the view so that the selected items appears at the top of the treeview's view (window). How would you solve this? Barry. Tag: Auto Hide AppBar Tag: 111701

    - NumericUpDown.Select(Int32, Int32) does not work - Bug? (.Net 2.0) I want to select the Text in a derived NumericUpDown control when the user enters the control by overriding OnEnter() and within this method calling this.Select(0, this.Text.Length). However, the behavior is not as I expected - nothing happens. Further more, Visual Studio does not offer the Text Property in its AutoCompletion, even though the Text property exists in the NumericUpDown Class. Does anybody have any ideas why this strange behavior occurs with the NumericUpDown control? Regards Stephan Tag: Auto Hide AppBar Tag: 111700

    - How does DataGridView get its tool tip text? Where does DataGridView get its ToolTip text? I've got a DataGridView in which I've placed a RichTextBox derived column. Most of the time, the tool tip gets its text from a call to DataGridView's CellFormatting method. Because the cell is RichText, I have to strip out the RTF formatting and so I have a function that does that and it is embedded in the CellFormatting method. However, there are times when the bubble help displayed appears to come from some place other than CellFormatting. The bubble help can sometimes display the raw RTF. So- what are the possible places that a DataGridView can go to get its tool tip text? -- Richard Lewis Haggard General: www.Haggard-And-Associates.com Please come visit here for a couple thousand good giggles!: www.haggard-and-associates.com/Humor/humor.htm Tag: Auto Hide AppBar Tag: 111690

    - Form Level Keyboard Handling I'm having a little trouble creating a global keyboard handler with the functionality I need. I want the form to handle all the keystrokes, which works perfectly when the form's KeyPreview property is set to true. However, there are instances when if a certain control has focus, I want the keyboard handling to be controlled by that control. Is there any elegant way to do this? I thought about setting the form's KeyPreview event to false in the control's Enter event handler and true in it's Leave event handler, but that didn't seem elegant to me. Any help would be appreciated. Thanks. Sergio Tag: Auto Hide AppBar Tag: 111678

But I want to know in case user does not select any date and closes DateTimePicker control by pressing escape key. Here in this case also I am getting today's date even if user did not select any date in that control.

    - Backup database from code: Access denied on user specific directories I want to backup a sql express database from my windows forms C# code. I can do this by running a sql command "BACKUP DATABASE TO..." (or using SMO) and I can save the backup file to any subdirectories of C:. The problem I have is that I want the user to be able to save the backup file to any location, including C:\...documents and settingsm\my documents... However, the file access for these directories (user specific) are more limited and the BACKUP DATABASE command fails due to Access Denied. Should I mess with the ACL to grant NETWORK SERVICE read/write permissions on the directory they want to save to? I am not very comfortable doing this as I don't like the idea of changing the ACL security on someone's system. The simplest solution is for me to restrict where they can save the backup file (to subdirectory of C:\), but if there are any other solutions, I'd like to hear them. Thanks.

    - using DateTimePicker with null entries Hi I have a windows form that includes a datetimepicker control. The form gets its data from a ASP Web service. The database field that supplies the data to the DTP control can have null entries. Unfortunately the DTP control either displays the correct date when there is data in the field but when there is no data (null), it displays todays date. Is there any way of geting the DTP control to display nothing when there is no entry? Hoping somebody can help. Kind regards Ross Petersen Tag: Auto Hide AppBar Tag: 111652
