    - Symbol does not display in RichTextBox but does in Word This is an obscure question, but I'm hoping someone may have experienced something like it. My program uses RichTextBox controls for all the text. Currently text in the Kannada language is being entered into it using the font KN-TTUma (ttf). One symbol in particular, the "Soft Hyphen", U+00AD, Keystroke Alt+0173, shows up fine in Microsoft Word, but it does not display at all in the rich text boxes. It also does not display in WordPad, so it's not just a Windows Forms problem, it seems to be rich text in general. Here is the rtf for the symbol in question. If I save this as symbol.rtf it does not display in WordPad, but it looks fine in Word. {\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fdecor\fprq2\fcharset0 KN-TTUma;}{\f1\fnil\fcharset0 Microsoft Sans Serif;}} \viewkind4\uc1\pard\f0\fs28\'ad\f1\fs17\par } Has anyone ever run into a problem like this where a font character does not display?

    - Postponed Form Visible While painting Hi, I have a form which is full of controls (also 3rd party controls like Infragistic). Now because this form is full of controls its take some time until it complete to be painted (and I don't want that the user will see a delay in the paining). I'm looking for a way to paint the form on the background and only when it finishes to be painted that to show it to the user. Thanks. Tag: [Datagrid] How to optimize the refresh of the grid?

    - No Vertical Scroll Bar in DataGrid! I have a DataGrid that lies on a TabPage with a TabControl, and when I associate the DataSource with a DataTable that has more rows than can be displayed, I do not see any scroll bars! I cannot figure out why they are not being drawn. If I click on a cell, then my mouse scroll-wheel will work, but when I hit the botm of the list, the focus seems to jump to some other DataGrid on the same Form.

    - Mulilanguage Windows Application Dear All, I'm developing a Multilanguage application using C# that supports English and French and Arabic. I have created the Forms with the default language and changed the language to each of the languages that I want to support and do any locale specific changes. Now I have each Form with all its resources needed for all languages I want to support. I want to put menu items that switch the application interface instantaneously between languages that the application support without restating the application. I have tried to change the current thread CultureUI to the new culture then call the InitializeComponent() method but it gives strange results. How could I do that??

    - Problem with ComboBox Hello Iâ??m experience a problem with a combo at VB .NET. Iâ??m developing a window application and Iâ??m using a combobox. Iâ??m populating the combo with a dataset. I set its ValueMenber and DisplayMenber, and the selectedindex to -1. The dropdownstyle is set to DropDown, but the problem persists whit DropDownList. When I click in the button, it shows a message box whit theValueMenber and DisplayMenber. Them I set again the selectindex to -1. The problem is that the selectedIndex that the combo assume is 0, therefore it show its first value. This is the code that I use. Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim objset As New DataSet Dim str1 As String objset = SP_Combo(strcon) 'cb1.DataSource = objset.Tables("Destinos") cb1.DataSource = objset.Tables("Empregados") 'cb1.DisplayMember = "nome" cb1.DisplayMember = "FirstName" cb1.SelectedIndex = -1 Match = -1 objset.Dispose() objset = Nothing End Sub Public Function SP_Combo(ByVal strConn As String) As DataSet Dim a As String Dim objComm As New SqlCommand Dim objDataSet As New DataSet Dim ObjdataAd As New SqlDataAdapter Dim objConn As New SqlConnection(strConn) objConn.Open() With objComm .Connection = objConn .CommandType = CommandType.Text .CommandText = "Select EmployeeID, FirstName from Employees order by FirstName" '.CommandType = CommandType.StoredProcedure '.CommandText = "SpNet_DestRecp" '.Parameters.Add(New SqlParameter("@Var_Onde", "Combo")).Direction = ParameterDirection.Input End With ObjdataAd.SelectCommand = objComm 'ObjdataAd.Fill(objDataSet, "Destinos") ObjdataAd.Fill(objDataSet, "Empregados") objComm.Dispose() objComm = Nothing ObjdataAd.Dispose() ObjdataAd = Nothing objConn.Close() objConn.Dispose() objConn = Nothing Return objDataSet End Function Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Match <> -1 And cb1.SelectedIndex = -1 Then cb1.SelectedIndex = Match Match = -1 End If If cb1.SelectedIndex <> -1 Then MsgBox("Numero: " & cb1.SelectedValue & " com o nome " & cb1.GetItemText(cb1.SelectedItem)) MsgBox("Indice: " & cb1.SelectedIndex) End If cb1.SelectedIndex = -1 End Sub To resolve this issue I populate the combo again. But this makes the application slower. Thereâ??s anyone who knows to resolve this little problem? Thanks to all. Ana Rita Tag: [Datagrid] How to optimize the refresh of the grid? Tag: 76833

    - COM Add-in toolbar click events only fire once if window is initialized This is a very bizare problem. So, I have a C# COM Add-in for Excel which creates a toolbar, then pops-up meaningful windows when you click the toolbar buttons. Everything works fine the first time. After that, my event handlers do not get called when I click the toolbar handlers. I've isolated the problem down to initializing a dialog window (never actually showing the window). Explicitely, the VisualStudio IDE is initializing the first component, failing on: this.instructionLabel.Location = ((System.Drawing.Point) (resources.GetObject("instructionLabel.Location"))); in InitializeComponent(). If I comment out the rest of the initialization code from this line to "this.ResumeLayout(false);", the event will fire every time. Note that there are plenty of lines before this with plenty of equally 'severe' calls: System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(AuthenticationPopup)); this.instructionLabel = new System.Windows.Forms.Label(); this.userIdLabel = new System.Windows.Forms.Label(); ... this.SuspendLayout(); ... this.instructionLabel.Anchor = ((System.Windows.Forms.AnchorStyles) (resources.GetObject("instructionLabel.Anchor"))); ... Unfortunately, this isn't a clear relationship, as I can't duplicate it in a simple sample app where I create the add-in, toolbar, form (localized), and one simple label. Other things happening: - If I comment out all of the form stuff, there is also a networking class that basically does XML-RPC http client calls that causes the same problem. Commenting out the 2 together allows for multiple firings. - I was previously developing this app as a simple COM interop application launching it from some Excel VB code. This issue wasn't present in that mode. Thanks, Carlos versions: .NET 1.1, OfficeXP, VisualStudio.NET 2003 (latest service packs) Tag: [Datagrid] How to optimize the refresh of the grid? Tag: 76800

    - Simple use of ToolTip in VB not working OK, my understanding of the simple use of the tooltip is to do the following: Drag the ToolTip from the toolbox on to your form. Once this is done all the controls have a new property added to them called "ToolTip on ToolTip1" (default name). For each control you can go and enter the specific text for that particular control. Then when the mouse is hovered over your controls any ToolTips you've defined for the controls should be displayed. I COULD NOT GET THIS TO WORK until I did the additional step: On my first control I added an event handler for mouse over as follows: Private Sub lblAddOne_MouseHover(ByVal sender As Object, ByVal e As _ System.EventArgs) Handles lblAddOne.MouseHover ToolTip1.SetToolTip(sender, "Move Selected Items From List 1 to List 2") End Sub Once I added this code the ToolTip on the first control worked fine. I then just configured the properties of the second control's ToolTip and IT worked fine without any extra code! What am I missing here? TIA.

    - TextBox carret not placed correctly Hi, When a user clicks a TextBox on a modal form, the caret immediately moves to the clicked location within the existing text. On a non-modal form, the user's TextBox click sets the focus appropriately, but fails to set the caret. How do I correct this behavior? When the user clicks in the midst of a word within a TextBox, the caret should be placed precisely between the two characters at the click-point. Any ideas? Thanks...

    - AutoScroll property Hi, I have a very long Form whose AutoScroll property is set to true. The user can easily scroll vertically through the form. The problem is that as the user drags the scroll marker up and down, the form doesn't actually scroll. Instead, the user must release the mouse button before the form redraws. Is there any way to make scrollable forms behave like every other Windows application on the market (Word, VS.NET, etc.) in that the view would actually scroll in real-time as the user drags the scroller knob?

    - AutoScale and MDI child maximized forms Hi, We have developed a MDI application using small fonts, when running the application in a Large fonts setup it works ok AS LONG we make sure that the mdi child forms open in normal mode (not maximized), if they open maximized the control on the right and bottom of the form are lost (because the controls are wrongly resized). I do want the controls to resize... what i don't want is it to fail while it does it. Also: we worked around it so any time you open a form it opens normalized instead of maximized (and that works fine, but it is a workaround). Is this a bug?

    - Form.Close() returns void? Hi, At a certain point in my application, I have access to a Form object. I want to close that form: form.Close(); There are any number of reasons why this form might not close. A common reason might be that the user answered "No" when the form's OnClosing() override asked him "Are you sure you want to close this form?" It seems like Form.Close() should return a *bool* indicating whether or not the closure was successful. I can think of lots of tricky workarounds to get a hold of this value, but the fact that Close() isn't designed to return this crucial value directly makes me wonder if I'm using the wrong approach to close the form. Is there another method that I should consider? Thanks... Tag: [Datagrid] How to optimize the refresh of the grid? Tag: 76746

    - Databound Combobox doesn't call SelectedIndexChanged event I have a databound drop-down-list style combobox that is databound to a dataset. Initially there are no items in the dataset/list. But when I later do a Fill on the dataset when data is present. When this happens, one item is added to the listbox and that item becomes selected. However, the SelectedIndexChanged event is not getting called. If I select the item again in the GUI, then the event does get called. Why isn't it getting called initially? I tried creating a basic combobox that is not databound and tried adding a single item to that list in code. The event gets called correctly in this case. So it apparently is just when the item is generated from the data binding that the event isn't called. Tag: [Datagrid] How to optimize the refresh of the grid? Tag: 76739

    - Adding Controls to a User Control at Design Time I posted this to ms.p.d.framework.windowsforms.controls but the only response was from somebody who had the same problem. Can anybody here give me any guidance - or suggest a more appropriate group? I am building a small control with two panels and a splitter. When I use the control in designing an app at design time I want to be able to add this control to my form and then drag other controls on to it to be contained within the panels. Although I can drag controls on to it they do not get 'captured' by it. I added a couple of properties so that the contained controls can be specified but I would rather go the drag and drop route.

Please let me know if you know of something I'm missing or how I might be able to get additional support (even pay support).

    - Work Offline Solution Needed Hi am about to create a N-Teir Solution Using SQL Server 200 as the Data Teir, XML Web Services as the Business Layer and Winforms as the presentation layer. I will be using Datasets that will peridically update the data back to the SQL Database. I wish to implement a Work Offline feature. That works now, untill the App is closed. What are best practices for storing data locally. Keep in mind that this application will rely on web services to get data and stored proceedures etc. Is there a solution already for this IE a namespace?

Hi NG,

I'm using a datagrid which is bound with copies of remote objects in my app.
It works quite well but the problem is that the grid refresh is very very very slow.
I'm refreshing only two fields by row (using Invalidate(Rectangle)).

Does anyone know how to optimize the refreshing?
Thanks for you help

One thing to note is that when the datagrid refreshes, it refreshes the
entire data and not just the invalidated regions. You can test this by
changing some values and then invalidating a region that does not
contain that value, you will see that infact the entire datagrid is
being refreshed.
