    - OutLook Calendar API? I working on an application the is, Globalizable and Localizable, and using a MonthCalendar Control. I want to be able to populate my calendar control with a holiday schedule like OutLook 2003 does. For an example do the following: Add another country's/region's holidays To add holidays to the Microsoft Office Outlook 2003 calendar, you must first remove any holidays that might remain in your Calendar from an earlier version of Outlook for the country/region whose holidays you want to add. After you have deleted those holidays, follow these steps: 1. On the Tools menu, click Options, and then click Calendar Options. 2. Click Add Holidays, and then select the locations whose holidays you want copied to your Calendar. Is there an API I can access from the development environment to allow me to bring up the list of countries? Is there an API to let me get a list of holidays for a specific country or list of countryies if I set the country? Thanks, Charles Tag: Custom display format for databound combo box Tag: 76873

    - Complex question about using collections from derived Controls in V. Studio Designer Hi, I'm writng a control derived from UserControl (let's call this control MyControl) that itself is meant to be derived further times. MyControl hosts a public collection of specialized non-GUI objects. This collection is therefore accesible from any controls derived from MyControl. Derived controls have to be able to add, change and remove objects from the collection. In MyControl I set the DesignerVisibility to Content so that the code-generation engine properly generates the code for the collection and when I initialize MyControl, I add some objects to the collection. Now, here's where the problem starts. The code generation for controls derived from MyControl will generate code to create and add all objects in the collection, even if some of these were added in MyControl and there's already code (in MyControl) to create and add them. The situation is similar to that of the ControlCollection in Controls, but here somehow, the code-generator doesn't add controls present in the super-calss again. I could not find any references or documentation of how to deal with this, so I'm asking for some help. Has anybody had some experience with this? Sebastian PS: I'll post some code if anybody needs an alternative explanation. Thanks Tag: Custom display format for databound combo box Tag: 76871

    - RichTextBox requires tons of memory for text VS.NET 2K3 and .NET 1.1 I'm having a problem with RichTextBox allocating huge amounts of memory for text. I have recreated the problem in the attached sample which, when the button is pressed, will create a ~33MB file and load it into the RichTextBox. If you watch the memory in Task Manager, before the button it consumes ~15MB max, but after it's finished, the memory is upwards of 140MB. Immediately invoking the GC doesn't seem to help. I've tried different things to no avail. Strangely enough, if I minimize the window, or maximize and restore, it will go down to something I could at least understand. I thought it might be related to http://support.microsoft.com/?kbid=826981, which fix was included in the recently released SP1. I retested the issue using the service pack, but it's still there. What can I do to fix this? ==================================================== Walter Williams Software Engineer Sawtooth Software, Inc. http://www.sawtoothsoftware.com ---------------------------------------------------- "Do, or do not.

    - Form Real FullScren Question Hi all, I have a following inquiry. Here in news group I found the sample code of how to put a window form in FullScreen (in the style VS 2003/2005 does) protected override void OnLoad(EventArgs e) { base.OnLoad (e); Point clientTL = this.PointToScreen(new Point(ClientRectangle.X, ClientRectangle.Y)); Point clientBR = this.PointToScreen(new Point(ClientRectangle.X + ClientRectangle.Width, ClientRectangle.Y + ClientRectangle.Height)); Point frameTL = this.Location; Point frameBR = new Point(this.Location.X + this.Width, this.Location.Y + this.Height); int topXDelta = clientTL.X - frameTL.X; int topYDelta = clientTL.Y - frameTL.Y; int bottomXDelta = frameBR.X - clientBR.X; int bottomYDelta = frameBR.Y - clientBR.Y; Rectangle newFrameBounds = Screen.GetBounds(this); newFrameBounds.Inflate(topXDelta + bottomXDelta, topYDelta + bottomYDelta); newFrameBounds.Location = new Point(-topXDelta, -topYDelta); this.MaximumSize = newFrameBounds.Size; this.MaximizedBounds= newFrameBounds; } But if I want that "fullscreen" behaviour to be complete how to round that when leave "fullscreen" mode, click on maximized button of form that from will be not in "real" maximized state - even more form will again in "fullscreen" mode. If anybody has any suggestions of how this is happen in VS 2003/2005 ? Tag: Custom display format for databound combo box Tag: 76866

    - Prevent Designer Generated Code I've created a button class (MyButton) that derives from System.Windows.Forms.Button. In the constructor, I set the ForeColor and BackColor properties of the button with a static color like this: this.ForeColor = StaticForeColor this.BackColor = StaticBackColor It's really important that the Designer Generated Code doesn't set the ForeColor and BackColor at design time. Is there a way to prevent the Designer Generated Code from doing this? Let me explain why. My idea behind creating a class this way, is so I can set the colors of the button for the whole class dynamically in my project when the project is loaded like this: MyButton.StaticForeColor = Color.Blue; The problem is, the Designer Generated Code automatically puts in lines like this: this.MyButton1 = new MyNameSpace.MyButton(); // // MyButton1 // ... this.btnBuildingView.BackColor = System.Drawing.Color.Black; this.btnBuildingView.ForeColor = System.Drawing.Color.FromArgb(((System.Byte)(0)), ((System.Byte)(102)), ((System.Byte)(255))); And even though the button class (MyButton) the StaticForeColor is not initialized, it's just: public static Color StaticForeColor; The Designer Still generates code for the ForeColor and BackColor in the // // MyButton1 // section because I set those values in the constructor. So, during runtime, no matter what I change the StaticForeColor to, the button will have it's ForeColor set to the StaticForeColor but immediately afterwards, it will be reset to: this.btnBuildingView.ForeColor = System.Drawing.Color.FromArgb(((System.Byte)(0)), ((System.Byte)(102)), ((System.Byte)(255))); or something like it.

    - How can I find the "natural" height of a property grid I want to size a panel to contain a label followed by a PropertyGrid such that the panel is the sum of the heights of the two properties (so that the PropertyGrid doesn't have to scroll, but also doesn't have any unused space after it). How can I find out what the "natural" height of the PropertyGrid would have to be set to to achieve that? (The scrollbar must somehow know when to appear). And also, as the user opens nested complex properties, how would I track the change to the height? Thanks for any help you can provide.

    - 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?

    - 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: Custom display format for databound combo box 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: Custom display format for databound combo box 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.

I do want the controls to resize... what i don't want is it to fail while it does it.

    - 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: Custom display format for databound combo box Tag: 76746

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: Custom display format for databound combo box Tag: 76739

    - form spawning on its own I have a form that uses the UIP app. block for navigation. The app is a testing application. The first part is the tutorial test. The 2nd part is the actual test. Both parts share the same form. When I go from the tutorial to the test part, a new form is spawned by itself. This didn't used to happen. I think it started happening after I was working on a section that changes the current culture when a button is clicked. I'm not doing anykind of new() calls on the form, it just spawns automatically. Does anyone know any ideas to help figure out why? thanks a lot!

    - 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. Any pointers or examples that you are aware of?

    - OCR with MODI Hi! I'm using MODI activex from Microsoft Office 2003 and Microsoft VB.NET to get the text from an OCR acquired image. Why after OCR the image, the MODI component rotate the image? Sometimes the MODI rotates the image 90 degrees and the OCR, obviously, can' t do its job. Any ideia why this is happening? There is my code: Dim miDoc As MODI.Document Dim miWord() As MODI.Word Dim strWordInfo As String Dim i, j As Long Dim str As String Dim Cont As Long Dim IMG As Long miDoc = New MODI.Document miDoc.Create("C:\MultiPage.tif") str = "" Cont = 0 IMG = miDoc.Images.Count - 1 miDoc.OCR(MiLANGUAGES.miLANG_ENGLISH, True, True) For j = 0 To IMG miDoc.Images(j).rotate(0) For i = 0 To miDoc.Images(j).Layout.Words.count - 1 ReDim Preserve miWord(Cont) miWord(Cont) = miDoc.Images(j).Layout.Words(i) Cont += 1 Next Next For i = 0 To miWord.Length - 1 str = str & " " & miWord(i).Text Next miDoc.Close(False) miWord = Nothing -- Cumprimentos, David de Passos -------------------------------------------------------------- RCSOFT, Lda.

    - Windows Forms through IE I have an ASP/SQL project that we are looking to port to .Net. At this point, much of the functionality is handled using DHTML and RDS. We have been looking to change over to something like a DLL that is displayed in IE. I have seen some writeups that indicate that windows forms can be displayed in IE, but I can't find anything to confirm this or to tell me how to do it. Can anyone help me out here?

I would like to be able to customize how data is displayed in my databound
combo box. The user will be selecting one of these values which will
correspond to a row in the database. However, I do not want it to display
in the selection items simple a single value from each row. I would like
for it to display a combination of two column values. For instance, suppose
I have this data:

ID, value1, value2
--------------------
1, data-A1, data-A2
2, data-B1, data-B2

And I want the combo box to display the items like this:
"data-A1 and data-A2" with value of 1
"data-B1 and data-B2" with value of 2

I could do this by selecting composite data in my original SELECT statement,
with: value1 + ' and ' + value2 as DisplayValue. However, this won't stay
current as I update the rows in the local cache. Is there a way to have the
databound combo box's composite display automatically update as the rows are
being modified?

You can use a DataView with a column that has an expression set to the
concatentation of the two value fields.
