    - newbie: Basic input dialog? I have a WinForms app that needs to take user input on open - before the FormMain is displayed. On the Form Load event of FormMain, I test for existence of an Access database: if (!File.Exists(Application.StartupPath + "\\myAccess.mdb")) If the mdb is not there, I need to open an input dialog form (with some additional options) for selecting a different mdb: FormDialogDifferentDatabase frmDialog = new FormDialogDifferentDatabase(); frmDialog.Show(); How do I suspend execution of the code in the FormMain while the user selects a different database? FormMain requires access to the database, so I don't want to initialize it until it has a database. Should I put this code in the constructor of FormMain? Also, how do I get the user input from FormDialogDifferentDatabase? Do I use DialogResult? I looked for examples of this but still confused... Thanks in advance. Tag: Interop with OpenOffice?

    - Q: How to highlit cell with changed value in DataGrid Hi All! My app uses databound datagrid control (binds to DataSet containing several DataTables and DataRelations). The data in DataSet are being updated what changes some cell values in DataTables (changes are made only to cells with new values). My problem is that I look for an efficient method to highlit changes in DataGrid control (preferable by changing BackColor and ForeColor properties of given cell) to alert user to new vaules. My attempt to catch TaxetChanged event in DataGridTextBox failed flat - changes in DataSource do not trigger that event. Monitoring of DataSet and DataTables obviously is possible, howoever, I would find it to be more elegant to constraint all the highliting code to DataGrid control. Any ides?

    - Moving a control inside an Autoscroll Panel Hi, I need to create a control that the user may move within a panel. It works fine until I add it to a panel that has AutoScroll. The control has a transparent background, but I don't think it would be the problem. This is my actual code, most taken from web pages: > bool dragging = false; > int mousex, mousey; > > void DrawViewer_MouseUp(object sender, MouseEventArgs e) > { > if (dragging) > { > dragging = false; > Cursor.Clip = Rectangle.Empty; > this.Invalidate(); > } > } > > void DrawViewer_MouseMove(object sender, MouseEventArgs e) > { > if (dragging) > { > Point MPosition = ((ScrollableControl)this.Parent).PointToClient(MousePosition); > MPosition.Offset(mousex, mousey); > this.Location = MPosition; > //this.Invalidate(); > } > } > > void DrawViewer_MouseDown(object sender, MouseEventArgs e) > { > if (e.Button == MouseButtons.Left) > { > dragging = true; > mousex = -e.X; > mousey = -e.Y; > int clipleft = ((ScrollableControl)this.Parent).PointToClient(MousePosition).X - this.Location.X; > int cliptop = ((ScrollableControl)this.Parent).PointToClient(MousePosition).Y - this.Location.Y; > int clipwidth = ((ScrollableControl)this.Parent).ClientSize.Width - (this.Width - clipleft); > int clipheight = ((ScrollableControl)this.Parent).ClientSize.Height - (this.Height - cliptop); > Cursor.Clip = ((ScrollableControl)this.Parent).RectangleToScreen(new Rectangle(clipleft, cliptop, clipwidth, clipheight)); > //this.Invalidate(); > } > } I tried both overriding and handling the mouse events. I also thought at first the problem could be the Clip, but I finally discarded it. The main two problems are: 1) If you move the mouse fast, it starts mis-behaving. 2) If you go beyond the limits of the actual portion of the panel (when AutoScroll starts to work), the scrollbars start to go up and down, and the control gets out of control :-) Any ideas?

    - DbType vs SqlDbType I've been experimenting with various ways of "talking to the database" mainly a low maintenance way to switch between sql and access. I've finally got something a pretty comfortable with except for this why does this work ok param=new System.Data.SqlClient.SqlParameter(); param.DbType=paramType; param.ParameterName=paramName; param.SourceColumn=paramSourceColumn; param.Size=paramSize; and this does not //now this will give a compile error about converting to sqldbtype from dbtype System.Data.IDbDataParameter param=new System.Data.SqlClient.SqlParameter (paramName,paramType,paramSize,paramSourceColumn) ; //so now i typecast wich does compile ok but doesn't work System.Data.IDbDataParameter param=new System.Data.SqlClient.SqlParameter (paramName,(System.Data.SqlDbType)paramType,paramSize,paramSourceColumn) ; the first scenario works but it gives me concern that it may not be a good thing to do because otherwise i would expect an overload of the new SqlParameter to include dbtype Any explanation of what i'm missing would be greatly appreciated i've been messing with this for a couple of hours now -- Message posted via http://www.dotnetmonster.com Tag: Interop with OpenOffice?

    - UserPaint a TextBox - issue with WM_PRINT I am creating a custom textbox that requires me to handle the OnPaint mechanism. Currently, I am using WM_PRINT to draw the text in the textbox and am running into a problem. The text will never follow the font that is specified by the textbox, it is always the same no matter what I change it to. Is there some way to get WM_PRINT to use the font that the textbox is set with? I stripped down the code for my class to the following to show the issue: using System; using System.Windows.Forms; namespace TransTextBox { public class MyTextBox : TextBox { public MyTextBox() { this.SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint | ControlStyles.DoubleBuffer | ControlStyles.SupportsTransparentBackColor, true); } protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { System.IntPtr hdc = e.Graphics.GetHdc(); this.SetStyle(ControlStyles.UserPaint, false); try { const Int32 WM_PRINT = 0x0317; const long PRF_CLIENT = 0x00000004; Message m = Message.Create(this.Handle, WM_PRINT, hdc, new System.IntPtr(PRF_CLIENT)); this.WndProc(ref m); } catch { } finally { e.Graphics.ReleaseHdc(hdc); this.SetStyle(ControlStyles.UserPaint, true); } } } } I appreciate any help - thanks.

    - FolderBrowserDialog won't accept the My Documents (or below) folder for the selectedpath I want to set the selectedpath in the folderbrowserdialog to a subdirectory of my "My Music" folder, yet allow the user to traverse higher than that in the directory if they want (in other words I don't want to set the root folder to this My Music, I want to set it to My Computer). But when I use a selected path that goes to My Documents or below, it doesn't accept it. Now what I mean by doesn't accept, it doesn't return an error, it just doesn't open up that node. When I try to drill down past my documents, it just leaves me at the root. It works fine (selectedpath) up to the point of my username (or other subdirs past my username other than my documents), then after that, doesn't. I'm thinking that maybe it's some type of ACL issue, but I can use directory.getdirectories to list the directories just fine. The code is as follows: Dim fb As FolderBrowserDialog = New FolderBrowserDialog fb.RootFolder = SpecialFolder.MyComputer fb.SelectedPath = "c:\documents and settings\danhi\my documents" fb.ShowDialog() This fails to expand any of the nodes in the display. If I replace the selectedpath with something like "c:\documents and settings\danhi\start menu" that works just fine. Anyone have any idea what my problem is? Dan Tag: Interop with OpenOffice?

    - Arrow Key behavior for a Textbox inside a DataGrid I have a DataGrid, with a custom ColumnStyle that displays a user control. The user control has several TextBoxes on it. I would like these TextBoxes to act like normal textboxes with regards to the arrow keys--right and left would move the cursor, holding down shift would highlight text, etc. I can inherit from TextBox, and override the ProcessCmdKey and do all this explicitly, but that seems a lot like re-inventing the wheel. Is there another way to do this that essentially just tells the DataGrid to treat the TextBox like a real TextBox? Thanks Tag: Interop with OpenOffice? Tag: 90095

    - SystemTray Balloon Window suppressed with fullscreen apps? I read that the system tray balloon window will be suppressed when there's a fullscreen app running like a game or PowerPoint presentation. I've personally verified this behavior, but it doesn't seem to be smart enough to know that the task bar is on a second monitor. It just seems to check that a fullscreen app is running "somewhwere" and supresses the balloon notification. How do I suppress this behavior? I want the balloon windows to show whether there's a fullscreen app running or not. I'm using the NotifyIconEx C# control posted on CodeProject. It's pretty much a C# wrapper for the Shell_NotifyIcon() API call. I've looked at the common controls docs in MSDN and didn't see any flags or options in the NOTIFYICONDATA structure that would imply I could control that behavior. Any ideas? Or am I stuck with the default behavior? Thanks, Terry Tag: Interop with OpenOffice? Tag: 90094

    - Autoscroll scrollbar thumb position being reset upon focus change Given the following Form with a panel with autoscroll set to true and with enough controls at different locations to cause autoscrolling to be visibly on, there is a slight annoyance with the behavior of the scrollbar upon switching focus to another window -- the scrollbar thumb position automatically gets reset to zero upon the Form getting the focus back. When I open standard windows apps like Microsoft Word and scroll down a document and then lose focus by switching to another application and then regain the focus on that Word document, the scrollbar thumb position is same as it was upon losing focus. Is this a bug/feature that I need to work around by saving off the thumb position in the Control.LostFocus event handler and restore in the Control.GotFocus event handler? Or is there some super simple way like a property setting - (the more I learn C#, the more I realize that some things are ridiculously simple if you know what property to use -- e.g. using Control.UseWaitCursor property of a container control instead of having to worry about setting the Cursor property to WaitCursor for each control contained by that container). <code> using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace autoScrollTest { public partial class Form1 : Form { public Form1() { Panel p = new Panel(); this.Controls.Add(p); p.AutoScroll = true; for (int i = 0; i < 1000; i++) { Button btn = new Button(); btn.Visible = true; btn.Text = "Button " + i; btn.Location = new Point(0,i * btn.Height); p.Controls.Add(btn); } } } } </code> Tag: Interop with OpenOffice?

    - Drag/Drop an Image from a Web Browset I've implemented a drag & drop operation which allows an image (or a file containing an image) to be dropped onto a custom control. This works fine on dragging an image file already on my hard drive, but on dragging an Image from any web page in a web browser, I'm getting an "Out of memory" exception thrown, but there appears to be plenty of memory left. Why could this be happening ? NB. On dragging a web image, files[0] contains a reference to the image in my web cache (in short directory format), for example: "C:\\DOCUME~1\\JEREMYB\\LOCALS~1\\TEMP\\DisplayBannerImage.gif" Could this be why ? If so how CAN I implement dragging an image from a web browser ? Here's the relevant sections of code: public Form1() { InitializeComponent(); AlbumControl ac = new AlbumControl(p, atype, AutoLookup, cwidth /*, false*/); ac.AllowDrop = true; ac.DragDrop += new DragEventHandler(ac_DragDrop); ac.DragEnter += new DragEventHandler(ac_DragEnter); } private void ac_DragDrop(object sender, DragEventArgs e) { Image droppedImage = null; // Handle FileDrop data. if (e.Data.GetDataPresent(DataFormats.FileDrop)) { // Assign the file names to a string array, in // case the user has selected multiple files. string[] files = (string[])e.Data.GetData(DataFormats.FileDrop); try { // Assign the first image to the picture variable. droppedImage = Image.FromFile(files[0]); } catch (Exception ex) { MessageBox.Show(ex.Message); return; } } AlbumControl ac = (AlbumControl)sender; if (droppedImage != null) { // DO SOMETHING WITH IMAGE !! ac.MainImage = droppedImage; } // Force the control to be redrawn with the image. ac.Invalidate(); } private void ac_DragEnter(object sender, DragEventArgs e) { // If the data is a file or a bitmap, display the copy cursor. if (e.Data.GetDataPresent(DataFormats.FileDrop)) { e.Effect = DragDropEffects.Copy; } else { e.Effect = DragDropEffects.None; } } Tag: Interop with OpenOffice?

Neither does posting a user message to this function by overriding the WndProc and calling Win32 [DllImport("user32.Dll")] public static extern Int32 PostMessage(IntPtr Handle, Int32 ConnectionType, IntPtr wParam, IntPtr lParam); ResetSelection() { listView1.Items[execScript.getCurrentExecNum()].Selected = true; listView1.Select(); listView1.EnsureVisible(execScript.getCurrentExecNum()); listView1.Focus(); } Neither does using a delegate like this listView1.BeginInvoke(new OnSelectedItemChangedDelegate(ResetSelection),null); Neither does adding a filter on to the listview control and trapping the LVN_ITEMCHANGING or LVN_ITEMCHANGED message in the WM_NOTIFY. Interesting to note though if I add a button to the form and call my ResetSelection() function it works fine. Three days I've spent on this. Can anyone help? Thanks Youngie...

I don't really want to have to traverse the entire tree every time, since it's a pretty big tree, so what I was trying to do was keep a list of all the checked nodes - I handle the aftercheck event so that every time a node is checked I add it to my list, and when it's unchecked I remove it from my list. This can become clumsy, though - for example, if I want to programmatically uncheck some nodes, I can't just iterate through my list and uncheck them, since that will modify the collection that I'm enumerating through.

    - Which form event to use? I want to show or hide controls on the form based on the value of an exiting public boolean value. Me.btnAddRow.Visible = bDataEntry Which form event does this belong in? putting it in the Form_Load event does not work. Should it be put in just after the initialize component? (I have verified that the boolean has the value.) Tag: Interop with OpenOffice? Tag: 90037

    - gdi+ book? Hi, there doesn't appear to be to many books on the topic. A couple of books had bad reviews on amazon. Im not wanting to get into really advanced gdi+ programming. I probably just use it to create controls. Nothing really advanced. Does Chris Sells book on Windows Forms go into enough detail with GDI+ Or do you need another book? If so which book would you recommend? Is " .NET Graphics and Printing: A Comprehensive Tutorial and Reference for Developers " any good? thanks, Brent Tag: Interop with OpenOffice? Tag: 90032

    - owner drawn ListBox repaint issues I am using variable height owner-drawn ListBox using new Visual Studio 2005 Beta. It appears to not repaint items in ListBox until I actually select them. In the constructor of my ListBox I call the following code: <code> this.DrawMode = DrawMode.OwnerDrawVariable; this.DrawItem += new DrawItemEventHandler(HandleDrawItem); this.MeasureItem += new MeasureItemEventHandler(HandleMeasureItem); this.HorizontalScrollbar = true; this.MouseDown += new MouseEventHandler(HandleMouseDown); this.MouseUp += new MouseEventHandler(HandleMouseUp); this.SetStyle(ControlStyles.ResizeRedraw | ControlStyles.OptimizedDoubleBuffer | ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true); this.UpdateStyles(); </code> Then in the DrawItem and MeasureItem code I do the following: <code> public void HandleDrawItem(Object sender,DrawItemEventArgs e) { if (e.Index < 0) return; e.DrawBackground(); //Draw control onto bitmap Control ctrl = (Control)this.Items[e.Index]; //using (Image tmpImg = new Bitmap(ctrl.Bounds.Width, ctrl.Bounds.Height)) //{ // using (Graphics g = Graphics.FromImage(tmpImg)) // { // Utils.ControlPainter.PaintControl(g, ctrl); // } // ////map ctrl location to viewport coordinates // //Point loc = ctrl.Location; // ////top left of viewport corresponds to // ////location of topCtrl // //Control topCtrl = (Control)this.Items[this.TopIndex]; // //loc.Offset(-topCtrl.Location.X, -topCtrl.Location.Y); // //g.TranslateTransform(loc.X, loc.Y); // e.Graphics.DrawImage(tmpImg, e.Bounds); //} e.Graphics.DrawString("item: " + e.Index, this.Font, Brushes.Blue, e.Bounds); e.DrawFocusRectangle(); } public void HandleMeasureItem(Object sender,MeasureItemEventArgs e) { if (e.Index >= this.Items.Count) { return; } Control ctrl = (Control)this.Items[e.Index]; ctrl.Location = nextLocation; e.ItemHeight = ctrl.Height; nextLocation.Y += e.ItemHeight; e.ItemWidth = ctrl.Width; HorizontalExtent = Math.Max(e.ItemWidth, HorizontalExtent); } </code> However, the painting doesn't appear to be done until I actually select the item. Do I need to invalidate the whole listbox initially and then every time I scroll? Tag: Interop with OpenOffice? Tag: 90027

    - *insert curse here* Hi I have a simple app where the user is prompted with a password dialog. When the password is being entered, the cursor is hidden as I assume is default XP behavior. The problem is when the user closes the dialog pressing the enter key (without any mouse movements done) the cursor will only reappear again when a mouse button has been clicked, not only by mouse movements. I have tried putting a Application.DoEvents() after the dialog closes but that only solves the problem when the cursor is located above the parent form. If the cursor is outside, it still won't reappear when moved back over the form. Any known reason for this? /Andreas Zita Tag: Interop with OpenOffice? Tag: 90024

    - MAPISendMail Hangs Hello Group! MAPISendMail hangs forever. It only works if in the VS.NET debugger I hit a breakpoint anywhere *after* MAPILogon and *before* MAPISendMail. Without breakpoint the app hangs forever on MAPISendMail. Funny thing is, if the app starts a minimised Notepad just before MAPISendMail, it (MAPI) will continue after which the app kills the Notepad proces. This is a very ugly trick. This problem occurs in a large MDI app but not in a small test Windows.Forms app! (If the MAPI calls are put on a separate thread then MAPILogin fails). What could be the reason and fix?

    - Serializing changes made to control via custom designer to source Got a custom designer that changes the arrangement of subcontrols in a custom control. It works fine, but if I save the form/rebuild the solution, exit out, and re-open the form, the subcontrols are back to their original place. I know I have to change how the custom control is serialized back to the code, and I believe it has something to do with Type Converters, but all I can find is information on how to serialize properties. Since this is not a property, but the order subcontrols are added to the custom control, I don't know how to deal with this. How do I go about doing this? TIA. Tag: Interop with OpenOffice?

    - Siziing UserControls via a custom ControlDesigner We need to know which edge of a UserControl is being stretched when in design mode. We've created our own CustomControlDesigner, derived from ControlDesigner for our UserControl. We can't find a way to determine which edge of the Designer/Control is being stretched when the control is being resized in design mode. We want to resize different fields within the UserControl, based on the edge being dragged. There does not appear to be a way to get a mouse-down event before the resize to see which edge the user is being dragged. Any Ideas? Thanks Tag: Interop with OpenOffice? Tag: 90011

In my application I would like to have a powerfull text editor.
RichTextBox falls a bit short of it.

I cannot assume my application's user would have MS-Word (it's not standart
part of the OS, hey!)

Is there any ways / examples of embedding OpenOffice TextControl in .NET?

Hello,

I've recently read about support for C# in OpenOffice 2.0. So you don't
even need COM to connect to OpenOffice 2.0. Documentation can be found in
the Developer's Guide, chapter 3.4. Since OpenOffice 2.0 has not been
released so far (except the beta version), you may also use Managed C++ to
create some wrappers.

greets

thanks for that!
yep I found this section but currently the don't even speak about .NET, I
guess best thing is to wait for 2.0 (OpenOffice 2.0, that is)....
