    - Populating a Combo Box with instances of a class - problem Hi! I'm feeling the burn of .NET; Still getting used to it :) I'm trying to populate a combo box with instances of a class: Public Class Shortcut Private Name As String Private RealLocation As String Public Sub New() Me.Name = "unknown" Me.RealLocation = "unknown" End Sub Public Sub New(ByVal Name As String, ByVal Path As String) Me.Name = Name Me.RealLocation = Path End Sub Public Function getName() As String Return (Me.Name) End Function Public Function getRealLocation() As String Return (Me.RealLocation) End Function Public Overrides Function toString() As String Return (Me.Name) End Function End Class My problem is the following code: With cmb .ValueMember = "getRealLocation" .DisplayMember = "toString" .Items.Add(New Shortcut("Label1", "Full Path1")) .Items.Add(New Shortcut("Label2", "Full Path 2")) .Items.Add(New Shortcut("Label3", "Full Path 3")) End With When the combo list isn't activated, the combo box shows the results of the toString function, for the specific instance that is selected. However, when I click the drop-down button, it shows a list of blank entries. Selecting a blank entry again shows the results of the toString function of the instance I apparently selected. How can I make each entry have a value whent he combobox drop-down list is showing, not just once a specific item in the list is selected. It's hard to make choices when there's only blank options =/. Thanks again! Tag: Inline custom editor in PropertyGrid Tag: 81267

    - ListView, IComparer & column-re-ordering... Hi All! I use a special ListViewItemComparer-class to sort items in a listview for any column, and I have also allowed column-reordering. So far so good, but if I click the columnheader of any column, and the columnorder is not 'default', the listview 'forget' my column-re-ordering (i.e 0 2 1), and sets column-order back to default (i.e. 0 1 2). Is there anyone that might know what I have forgot to code in my ListViewItemComparer-class? Some info: - I use VS 2003, framework 1.1 - I use SendMessage with LVM_SETCOLUMNORDERARRAY to set the columnorder at startup. TIA Per Rollvang Tag: Inline custom editor in PropertyGrid Tag: 81266

    - Threading Part 2 Hello and thank you for your assistance. I have attempted to accomplish what I need using delegates with no success. i.e. //Button Click// Dim PollThread As Threading.Thread PollThread = New Threading.Thread(AddressOf PollThreadAddress) PollThread.Start() End Sub Private Sub PollThreadAddress() frm1PollDatabase.TopMost = True frm1PollDatabase.ShowDialog() End Sub //Button Click inside frm1PollDatabase that raises an event inside the Parent Form// Delegate Sub FromMyPage() Dim MyDeleg As FromMyPage Private Sub ApplyMyPage MyDeleg = New FromMyPage(AddressOf DelegateFromMyPage) MyDeleg.Invoke() End Sub Private Sub DelegateFromMyPage() frm1Modify.showdialog End Sub ** frm1PollDatabase is created inside a new thread and must always be on top, which works fine. But when the user wants to send that data from this form to a new form (frm1Modify) the form is displayed but frm1PollDatabase becomes disabled because of the Showdialog method. I cannot use show for this form to be displayed. If the original thread (Main) displays this form wont it prevent this problem? The above code did not keep frm1PollDatabase from being disabled. Thanks Again, Chuck Tag: Inline custom editor in PropertyGrid Tag: 81256

    - Window subclassing and mouse events VS.NET 2003, VB.NET, .NET 1.1 I'm working on a part of a project that is re-creating the Office 2003 mail notification window. I have almost everything done except for one part. I need to allow the user to move the window by clicking and dragging anywhere in the window (the window has no title bar.) Per many different sources, I have overridden the WndProc() method of my window thusly: --------------------------------- Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) Call MyBase.WndProc(m) Select Case m.Msg Case WM_NCHITTEST If m.Result.ToInt32 = HTCLIENT Then m.Result = New IntPtr(HTCAPTION) End Select End Sub --------------------------------- When I run the form, all is well - almost. I have found that when I do this, I don't get any of my form's mouse events. I am doing a lot of hand-work here, so I have MouseEnter, MouseLeave, and MouseDown events coded. These perform various functions that simulate functionality I would normally get by using controls (buttons, linklabels, etc.) but chose not to use. My reasons for not using them is because of the functionality I am trying to simulate: 1. The form fades in to 20% transparency when it's shown. It then begins a timer for fade-out (time set by the user, with an application default provided.) 2. If the mouse moves into the form, it goes to 0% transparency (opaque). 3. If the mouse leaves the form, it returns to 20% transparency. 4. The form will fade away at the first opportunity - either when reaching the fade-out time, or when the mouse leaves the form, whichever happens *last*. Using controls caused MouseEnter and MouseLeave events to fire on the controls and form multiple all over the place, and I wasn't able to handle them in any sort of satisfactory way. So I dumped the controls and wrote it all by hand. Since I don't get the mouse events, nothing happens when the mouse moves within the form. The form does not go opaque, and the fade-out will happen even if the mouse is within the form. I suppose I could re-create the functionality within the WndProc() method, but I don't understand why I have to - since my custom WndProc() is not trapping mouse events, and the first thing I do is call the base method, those should still fire - right? What am I missing? Any help would be appreciated. TIA - Scott Tag: Inline custom editor in PropertyGrid Tag: 81249

    - Multiple minimize and maximize buttons appering on MDI menu contro Below is text of the simillar problem we are facing allready posted by another user on the net... I have created an MDI application. When the first child form is opened and maximized one set of minimize, restore and close buttons are displayed on the menu bar. After closing the child window a set of minimize, restore and close buttons remain even though the child form has been closed. EXAMPLE: http://novasolution.net/Error2-2.jpg When a second set child form is opened and closed a second set of minimize, restore and close are shown on the menu bar. Each time a child form is opened and closed, another set of controls appears on the menu bar. When I open a new child form the multiple sets of buttons disappear. When the child form is maximized, only one set of buttons displays in the menu bar. When the child window is closed another set of buttons is displayed on the menu bar. some how we are unbale find a solution to this problem.. Any ideas..

    - Forms pseudo MDI support While trying to implement a MDI Application I found that the Windows.Forms classes that implement this functionality don't actually use the WIN32 MDI API. Using Spy++ I found that the MdiClient class does not use the 'MDICLIENT' window class. I also hooked up a Messagefilter to look at the MDI messages send to the mdiclient, the only messages I saw were WM_MDISETMENU and WM_MDIREFRESHMENU.

    - UPDATE SQLTABELLE VS2003 C# Ich habe einen SQLDATAADAPTER erstellt und ein DATSET generiert. Diese Dataset stelle ich in einem DATAGRID dar. In der Tabelle ist das Feld UKID als Primärschlüssel definiert und damit werden keine Nullwerte zugelassen. Num füge ich im DATAGRID einen Satz hinzu und update den SQLDATAADAPTER(DATASET). Die neuen Sätze stehen in der SQl-Tabelle. Nun möchte ich aber im DATAGRID das Feld UKID (Primärschlüssel) nicht mit anzeigen und somit bei kann ich bei einem neuen Satz auch keinen Wert im DATAGRID dafür eintragen. Betätige ich dann den Button zum Update des SQLDATAADAPTERS erhalte ich folgende Fehlermeldung "Spalte UKID läßt keine Nullen zu ..." Wie kann ich dem Feld UKID einen Wert im Code zuweisen, damit ein neuer Satz im DATAGRID akzeptiert wird? Das heist, der Nutzer soll bei einem neuen Satz im DATAGRID nicht die UKID eintragen können, die soll im Programmcode mit einem Wert belegt werden.

    - Control layout problem with system large fonts I have seen many people stating that they have the same problem. I have the font DPI setting set to 125% normal size (from the Display Properties dialog when you right-click on the Desktop). If a Windows Form is more than simle (has many controls), then the most chance is that when the Form is shown in runtime, the layout is somewhat in right condition (Some controls might position beyond the visible client area). I am not sure if Microsoft noticed this problem. I think it is a very *BAD* problem, based on that Microsoft/Windows have been strong in user friendly GUI since their beginning. My $0.02.

    - Threading Hello, I am making a app that creates a thread to show a clipboard. If the clipboard is double clicked, another window is displayed, the event is handled inside the main app. What I would like to do is have the clipboard use the main thread of the application that called it to handle the new window. Is this possible and if so how would this be accomplished. ie. Form1 creates a thread and the thread displays Form2. Form2 when double clicked raises an event that creates a new form (Form3). The event is handled inside Form1. How can I get Form3 to be managed by the main thread (Form1)? Thanks, Chuck Tag: Inline custom editor in PropertyGrid Tag: 81225

    - Auto Expanding TextBox/Controls Hi there, I've googled this problem, and not found a suitable solution yet. I was wondering if anyone has made any progress? Basically, I want to make a textbox automagically adjust it's height to show all the text it contains. So, if I add text then it grows, and it shrinks if I remove text. This is similar to the CanGrow property in MS Access controls. I'm willing to purchase a control if anyone knows of any, I'd just like to get this cracked without spending *too* much time "fiddling" about!

    - User Control's Load event fires when the Dispose method executes I have a user control which is used as a data entry form and it is instantiated on a window form. When the windows form is closed via clicking on the top right red-X close button, the user control's Dispose method executes. When it executes the load event fires. Here's the dispose method: Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean) If disposing Then If Not (components Is Nothing) Then 'WHEN THE NEXT LINE EXECUTES, the controls Load Event Fires. components.Dispose() End If End If MyBase.Dispose(disposing) End Sub This user control also created instances of some other user controls used as sub-forms. I don't know if this has anything to do with it, but when the user clicks on the red-X close button of the parent form and things began to close, no cleanup code ran to kill the instances of these user controls. I will eventually have the proper cleanup code in place, but right now I want to understand why this load event fires when "components.Dispose()" is called.

    - DateTime Bound to TextBox Hi, I have bound a DateTime field in a DataTable to a TextBox field. Other String and Numeric fields are also bound to separate TextBoxes. If a new DataRow is created and a DateTime value is entered no problem. However, after the row is saved, I am unable to clear the date from the textbox. I do not have this problem when binding to a DataGrid. But a DataGrid is far from user friendly and just plain impractical in many situations. In its place I am loading the DataRow into a class and using unbound fields on the form. Bound controls seem great for strings. But thats about it. Does anyone have a better solution?

    - How to simply load a freeekin bitmap from a resource? I'm coming over from a background in VC++, and in general I've been pleased with the simplicity of the .NET environment. Not here. I've done google searches on this subject (loading bitmaps from a local resource) and always come up with complex solutions. This can't be right. Everyone packs bitmaps and other graphics and resources, integral to small executables, right? Setting up a local resource folder, loading in graphics, and setting their properties to 'Embedded Resource' would seem to incorporate them, as expected. Then what?

    - Deployed simple C#.NET single form application to Windows server 2003 and the form will not display, but application appears in the the task bar. I have a very simple C#.NET (Framework 1.1) application that is one form with standard .NET controls on it. The application requires a CONFIG file to work. When I install the application to Windows 98/2000/XP, I simply install the .NET framework and copy the EXE and CONFIG files to the workstation and double-click the EXE. This has worked fine for those Operating Systems. When I deployed this to a Windows Server 2000 machine, I just needed to do the same to get it to work (.Net was already installed). However, when I copy the EXE and CONFIG file to the Windows Server 2003 machine and double click the EXE, the form does not display any User Interface (the single form), however, an application block appears in the Task Bar (toolbar that contains the start button and system tray). I do not know what is causing this, and I have no idea how to fix this. I have searched the Microsoft Knowledgebase and googled some searches, but have found no information that has been helpful. I have tried to use the "Microsoft .NET Framework 1.1 Configuration" tool, but no luck. Any ideas or suggestions? Thanks, Roger Tag: Inline custom editor in PropertyGrid Tag: 81169

    - ScrollableControl Scrolling by Itself I have a UserControl with AutoScroll set to true. When my application loses then regains focus, the control scrolls itself to make ActiveControl visible. This also happens when I dynamically add or remove child controls. Is there any way to make the scrollbars stay put? Here's some sample code demonstrating my problem. Run the application then scroll down and right as far as possible. Button one will be scrolled out of view and button two will be visible. Switch to another program then come back. The scrollbars will move to make button one visible again. ---- using System; using System.Windows.Forms; using System.Drawing; public class TestScroll { public static void Main(string[] args) { Application.Run(new TestForm()); } } public class TestForm : System.Windows.Forms.Form { public TestForm() { this.ClientSize = new System.Drawing.Size(400, 400); this.Text = "TestForm"; container = new ContainerControl(); container.Dock = DockStyle.Fill; container.AutoScroll = true; this.Controls.Add(container); btnTest1 = new Button(); btnTest1.Left = 0; btnTest1.Top = 0; btnTest1.Width = 50; btnTest1.Height = 50; btnTest1.Text = "One"; btnTest1.Click += new EventHandler(this.OnBtnClick); container.Controls.Add(btnTest1); btnTest2 = new Button(); btnTest2.Left = 500; btnTest2.Top = 500; btnTest2.Width = 50; btnTest2.Height = 50; btnTest2.Text = "Two"; btnTest2.Click += new EventHandler(this.OnBtnClick); container.Controls.Add(btnTest2); } private void OnBtnClick(object sender, EventArgs args) { container.ActiveControl = (Control)sender; } private ContainerControl container; private Button btnTest1; private Button btnTest2; } ---- Apologies if this is a common question.

    - Hidding a window and preventing Alt-Tabbing to it I'm trying to hide the main form of my application, as I want all of the user interaction with my application to come from interacting with a notify icon with a context menu in the system tray (which I have working). I've figured out how to hide the form easy enough, set the WindowState to Minimized and ShowInTaskbar to False. What I can't figure out is how to prevent the user Alt-Tabbing to the window, as its still visible in the Alt-Tab menu. I can set the windows FormBorderStyle to FixedToolWindow or SizeableToolWindow and it will no longer show up in the Alt-Tab menu but now it will now minimize to the bottom left of the desktop just showing the windows title bar instead of being completely hidden! Does anyone know of any way to completely hide a window visibly(so no part of the window is visible anywhere), with no icon on the task bar or on the Alt-Tab menu? All I really want is to be able to run a notify icon in the system tray and a context menu for the icon but I'm don't know of any other way to do it other than to run it in a enclosing form. I've been wondering if making my application a service make things easier but I've no experience with programming services and it seems a bit of overkill for what I'm wanting to do!

    - Hello, Japan? My application is so successful that it needs to go global. The only problem is that that means Japanese. I don't know the first thing about making a Japanese language application. I know I have to use Unicode, but that's about it. In case it matters, the user will be presented with a dialog, and he can choose, dynamically, which language it should be rendered in. So, it isn't a matter of linking a particular resource file for Japanese on one machine, and a different one for English on a different machine. Both must be available, based on user choice. Is there a simple "Hello, World" application for the .Net framework, but in Japanese? Or any sample applications that make use of Japanese? I don't even know where to find a Japanese font. Any help would be appreciated. Tag: Inline custom editor in PropertyGrid Tag: 81155

    - Closing all instances of an application I start up several instances of an application I've written. From one of the applications I'm trying to close all of them, but it's not working. I'm doing this by registering a message and broadcasting it. but when I put a breakpoint in my overridden WndProc, It never seems to get the message. public class frmMyApplication : System.Windows.Forms.Form { public const int HWND_BROADCAST = 0xFFFF; [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern int RegisterWindowMessage(string strMessageType); [System.Runtime.InteropServices.DllImport(strUSER32DLL, CharSet=CharSet.Auto, SetLastError=true)] public static extern int SendMessage(IntPtr hWnd,[MarshalAs(UnmanagedType.U4)] int iMsg, int iWParam, int iLParam); int iCloseAllMessage_m; public frmMyApplication() { iCloseAllMessage_m = MediScript.RegisterWindowMessage("_CloseMyApps"); if (iCloseAllMessage_m == 0) { throw new Exception("RegisterWindowMessage returned 0"); } } protected override void WndProc(ref Message m) { if (iCloseAllMessage_m != 0 && m.Msg == iCloseAllMessage_m) { Application.Exit(); } else { base.WndProc (ref m); } } private void mnuiCloseAll_Click(object sender, System.EventArgs e) { SendMessage((IntPtr)HWND_BROADCAST, iCloseAllMessage_m, 0,0); } } Tag: Inline custom editor in PropertyGrid Tag: 81154

    - GroupBox disables event handlers in the user control it contains. Hi, friends, In my VC# windows program, when I put a user control in a GroupBox, all the event can no longer be handled, for example, DoubleClick. However, if I remove this GroupBox and put the same user control in the Form directly, everything works fine. I do not know what is wrong here. Any ideas? Thanks a lot.

    - Excel Add-In InvalidCOMObjectException On Shutdown Hi Guys, I've created an Office.CommandBarPopup Add-In for Excel that launches a Windows Form as a modal dialog when a button within the CommandBarPopup is clicked. However, when Excel is shut down I am receiving an InvalidCOMObjectException error. This is even happening even though the form has no embedded controls. It doesn't happen if the dialog isn't instantiated. Is there a procedure that needs to be followed when destroying forms from Excel add-ins? Best regards, Jim...

    - Monitor Dial-up Connection I am writing a smart client application that needs to monitor the users dial-up connection status. If the user disconnects, I need to prompt them to reconnect, or quit the application. I tried using the following WMI query wmiDialupDisconnect = New ManagementEventWatcher("SELECT * FROM MSNDIS_NotifyAdapterRemoval") but it does not work. Does anyone have any ideas how I can monitor a users dial-up connection status? Tag: Inline custom editor in PropertyGrid Tag: 81143

    - Panel & keyboard focus I have a panel and some of my controls on it (each control is derived from Control, not from UserControl). I need to delete the selected control by pressing the Del key. How it can be done? Panel does not process any keyboard events. Also I don't want to delete any controls when focus is on the other controls of the form. So the scenario is something like this: 1. User clicks on some of my controls (panel receives focus) 2. User press Del key (control removes from panel) 3. User press Tab key (the focus is received by another control of the form, but not a control of the panel) 4. User press Del key (nothing happens) So the main question is how can I monitor focus state of the panel and process the keygboard input? Thank you very much. -- With best regards, Mikhail Tag: Inline custom editor in PropertyGrid Tag: 81138

    - DataGridView tab order Hello, I have a DataGridView with several columns. I would like to change the tab order for the columns but I can not find a way to do this. There is no property to set the tab order. I could listen for the tab-keypress but I can not find a method setting focus on a specific cell in the DataGridView. What I really would like to do is to skip a column when using Tab to navigate the grid. Is this possible at all? Cheers, Chris Tag: Inline custom editor in PropertyGrid Tag: 81135

Hi,

Currently, possible values of UITypeEditorEditStyle is either model,
dropdown or none.

Is there no way to have a custom editor displayed inline within the
PropertyGrid?
Could be useful for custom editors such as mask edit etc.

Thanks,
Anita
