    - Forms from DLLs Hello, I have the following problem: I've several modules compiled in DLLs each one with their forms, etc... To centralize this I have an exe that has a MDI form in wich the mdi childs forms are called. However the event GotFocus, the property Focused, aren't runned! This way I never know when my mdi child gets focus. Any ideia? PS: I'm working in VB.NET Tag: BitBlt Only To Capture Area On Screen Tag: 76936

    - Drawing on PictureBox Hi, Just a quick question: I draw a rectangle on the PictureBox: pictureBox.CreateGraphics().Rectangle(rect); When i minimize the form and restore again, i loose all i've drawn. In what event handler i need to redraw the rectangle? I tried to call the draw function in PictureBox.Paint - doesn't work.

    - Problems with variations of the standard Listview demo program I'm simply messing with the listview control to better understand it. I'm wondering if I'm missing something basic. I took the example in VS Help, the one in the AddRange definition in which the Listview is created programmatically. What I wanted to do was create the ListView in the designer and only add the items and columns programatically. (I do not care about the graphics at this time.) All that I left was the creation of the subitems, the ListView1.Columns.Add, and the ListView1.Items.AddRange. I've changed the property settings of the ListView to match what is done programmatically in the example. I was going to say at this point that nothing happens but I've just found the problem (I think.) This however raises another question. I do not understand the -2 width argument in the ListView1.Columns.Add calls. If this is a form of default width control, I cannot get it to work. Could someone please point me to an appropriate reference, and explain to me how the original example works at all? (Maybe I should stop programming late at night.)

    - Windows Form Locking up I have developed a rather large application and am running into a bug that causes the application to lock up. No exception is ever thrown, it just simply refuses to take input. The only thing that you can do to the Form is double click the title bar to restore/maximize the window. Other than that the menus, navigation buttons, everything cease to respond at all to any user input. Windows continues to run properly and you can restart the application (END TASK) and it will run normally again. I noticed this error I while back and when it occured there would be a "WindowsFormsParkingForm" or something like that in the ALT-TAB list when the error occured. Now it doesn't do that anymore. It just causes my app to essentially freeze and cause my users to do a nasty IT functionality CTRL-ALT-DEL, end task. I have been unable to locate the error through debugging.

    - Is this a good use of MDI I'm developing a Windows Forms app that requires a fixed set of graphical nav buttons along the top of the app window, then a number of forms (or panels? or...?) that appear below, one at a time, based on the selection the user makes from the nav bar. I've seen in other postings refer to this a "MS Money navigation." I've looked at Money, and that seems about right. I've actually got everything up and running using an MDI parent to contain the nav stuff, and then some child forms set to fill the rest of the parent. The child forms are set to have no border, no max or min buttons, etc.--they basically look like panels. This works except for one major problem: I'm using show and hide methods to control the appearance of each form, but when I execute the methods, the title bar and border of the child forms briefly appear then disappear--it's a flicker, very distracting and annoying. I've searched for a solution, but haven't found one. So, I'm now wondering if this is the best way to handle this app. Perhaps MDI is not suited for this? If not, what would be a better solution? It seems that panels would be right, except difficult to put together at design time... Any suggestions? I'm on Visual Basic .Net 2003, 1.1 of the CLR, with the most recent updates.

    - strange problem with inerited user controls I have a strange problem with inherited controls: I have created two user controls called UserLoginA & UserLoginB. One of the properties of these controls is of type UserGroup ( a class I defined in another assembly). Then I show that UserLoginA & UserLoginB have a lot of common code, so I decided to inherit UserLoginB from UserLoginA. So I Created a new user control UserControlC that inherits from UserLoginA, added the code needed to make it work like UserLoginB, tested it, and everything worked just fine. Then I removed the file that defined UserLoginB from the project, and renamed UserLoginC to UserLoginB (so I will not have to change all the code using UserLoginB). Then the strange stuff started: Now when I try to drag UserControlB (that used to be UserControlC) on a from I get this error: Then I create an inherited user control called UserLogin2 that inherits from UserLogin. When I add these controls to the toolbox and try to drap UserLogin2 to the form I get an error: An exception occured while trying to create an instance of UserLoginB. The exception was "The type serialized in the .resources file was not the same type that the .resources file said it contained. Expected "UserGroup" but read ""UserGroup".". Does anybody have any Idea why this happens? Thanks, Nadav. Tag: BitBlt Only To Capture Area On Screen Tag: 76909

    - SupraText Open Source .Net Editor ... here it is (!) Ok, here's what I did all day ( besides baking an Eggplant Parmesan ). The SupraText Editor version 0.0001a : http://home.earthlink.net/~jabailo/Windopes%20SupraText/ Take down the binary and the four sample files here: http://home.earthlink.net/~jabailo/Windopes%20SupraText/bin/Release/ And run it in its own folder. 0. Select text in the middle window. 1. Drag a named anchor from the left hand window 2. Click on a different file in the right hand window. I'm also building a mono version, but right now I'm more adept at VS.net so I wanted to build the 0.1 version in VS.net and then re-engineer it in monodevelop. The idea of a SupraText editor is to build highly congruent, linked, text oriented web sites. The text and the hyperlink between the HTML pages becomes the main structural component. Well, it's not much to look at, but it's already helping me design my new website ;) Comments: jabailo@THIRDPLANETFROMSUN_link.net ( replace CAPS of course ) --- Outgoing mail is certified Virus Free.

If I use both, then the MouseDown event fires, when I change selection the SelectedIndexChanged does not fire ! I use the MouseDown for a DragDrop event. Sometimes I want to DragDrop from the ListBox to a TextBox; other times I want to respond to a simple change in the selected Index of the TextBox via a mouse click.

    - Objidl.h problem Every time I add a particular form to my VS 2003 C++ project, the project can no longer compile. The error message indicates an ambiguity because IDataObj is defined both in System::Windows::Forms and also in objdl.h. I have no idea why objidl.h is being included in my project, but it must have something to do with the objects in my form other than controls. There are no COM objects involved. The problem line in objidl.h is line 7408: typedef /* [unique] */ IDataObject *LPDATAOBJECT; Can anyone help me get past this compiler error? And maybe explain how objidl.h gets included in my project? Thanks for any help. Tag: BitBlt Only To Capture Area On Screen Tag: 76893

Can you suggest some properties of the TextBox that I might use to accomplish that ? Tag: BitBlt Only To Capture Area On Screen Tag: 76889

    - Validation in MDI children Hello In my MDI Application, I have an MDI Parent Form which contains two Child Forms, childA and childB. childA has a TextBox which has an Validating event Handler When the Users enters some text into this TextBox which does not pass the validating event, the Event Handler sets the Cancel Property of the CancelEventArgs argument to TRUE. The Cursor cannot leave the Texbox, which is excty what I want... but: When the user clicks on another MDI Child (e.g. childB), childB comes to front. The user can click on any Textbox on childB, he will not get the cursor into the Textbox, because the Cursor is held back in childA. The user thinks that the Application is not responding. It would be a lot better if I could prevent the User from activating childB as long as childA has Validation Errors. How can I do this?

    - Custom display format for databound combo box 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?

    - 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: BitBlt Only To Capture Area On Screen 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: BitBlt Only To Capture Area On Screen 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.

    - 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?

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: BitBlt Only To Capture Area On Screen 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: BitBlt Only To Capture Area On Screen 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. JB Tag: BitBlt Only To Capture Area On Screen Tag: 76794

    - disposing of SystemBrushes Hi If i create a Brush object I believe it is good practice to explicitly dispose it or use it within a using block.

I also would like to add my own Formatted Text box column. Is it possible to extend the current Datagrid to do this.

Hi is it possible to capture just an area of the screen using BitBlt
only and not StretchBlt or Graphics.DrawImage to crop the area of the
screen. I don't mind using some other APIs to accomplish this. Maybe
SetWindowRgn? But I don't know how to use.

Thanks,
Henry
