    - How Do I Capture Mouse Wheel Movements? I have a Microsoft wheel mouse. When focus is on a scrollable panel, I would like to capture mouse wheel movement events to make the panel scroll as the wheel is turned. I don't see a mouse wheel event in the Windows.Forms.Control or panel control. Is there a way I can capture this in .NET? Thanks. Tony Lin Fremont, CA Tag: TabControl & ComboBox Tag: 53385

    - Making An AltTab Program/Task Switcher Hi guys, just like to ask how do I go about making a task switcher? Specifically I'd like to know what are the actual WindowStyles and WindowStyleEx I should look for to determine wheter or not to include it in the list. I've already done the EnumWindows bit, excluded all the blank title, and invisible windows.. but I'm still getting duplicates.. like VS .Net which has a main window.. and a Hidden window?

    - Could not instantiate ActiveX control because the current thread is not in a sin Hi, I have a .NET .DLL called by a VB6 EXE. The following error message is when trying to instantiate a form in the .NET .DLL: Could not instantiate ActiveX control 'c932ba85-4374-101b- a56c-00aa003668dc' because the current thread is not in a single-threaded apartment Some documents suggest adding <STAThread()> proceeding the Main() method to enforce the .NET in running in the static thread. However, there is no Main() method in the .NET .DLL. Any one knows how to solve this problem? Appreciated very much. Tag: TabControl & ComboBox Tag: 53375

    - Icons and Listviews I've got a series of items in a listview that contain icons in the first column. These icons are basically squares of specific colors (i.e. red, yellow, dark gray). When one of the items is selected and subsequently highlighted, the selected color is also applied to the icon, changing it to dark gray. I was wondering it it were possible to allow the user to select and highlight an item, while maintaining teh color of the icon. Or, in other words, disable selection and highlighting on the first column. Hacks and inelegant workarounds will also be accepted! Thanks, Chris Tag: TabControl & ComboBox Tag: 53366

    - Unable to Merge Menus... Guys, I've created a simple MDI form with a Top-Level menu and another Form with a Top-Level Menu. I was under the impression that their menu items were supposed to merge when I loaded the sub-form as a child of the MDI form. However, nothing happens. No merging takes place. I can't seem to figure out what's going on here. I'm using VB.NET 2003. Any help would be appreciated. Thanks, Mike Tag: TabControl & ComboBox Tag: 53365

    - Transfer an event to a different control Hi A simple question: I have a form with a ListBox and a RichTextBox. The user selects the list box and types some characters. I am trapping KeyPress events on the list box, and want to simulate having the rich text box receive that key press, so that the characters would also appear in the text box. I don't want to alter the text of the text box programatically with SelectedText=, because the text box is also taking care of the effect of backspace and other key presses. I believe that if one control contains another, the event is passed up the container hierarchy until it is handled, so I could set Enabled=false. But how can I transfer the event between peer controls, and can this be done in managed code? Many thanks for your help, James Carlyle Tag: TabControl & ComboBox Tag: 53364

    - VS.NET Installer Documentation I was wondering if there is any documentation on how to create an installer using the VS.NET Installer Project. I have played with it and understand some. I am specifically interested in how to: 1) See if .NET is installed and install if necessary 2) See if a database is installed (MSDE) and install if necessary 3) How to create program groups and short cuts for the START Menu 4) How to see if there is a previous version of software on the machine and overwrite, not the default of uninstall and then install.

    - Long drawing loop cancellation Thinking about a standard "silly" problem of giving a user an option to cancel long drawing loop, I read a lot of articles and did some investigations of my own. (I work with C# .Net 2003). My application must provide a very sophisticated drawing, which is actually a millions-length sequence of simple line or ellipse drawings executed in a very long loop. Naturally, I'd like to give a user an option to cancel the drawing. I have a number of rather bad solutions and I don't see any acceptable one. The Solutions are: 1. The drawing loop is execute in the UI thread and calls DoEvents() to allow "Cancel" button to be pressed. The downside is well known (see DoEvents() method adoption discussions) ? UI thread is busy and natural events sequence is broken. 2. The drawing loop is executed not in the UI thread. The downside is seldom exceptions. Generally, as I know, .Net does not allow drawing from non UI thread. 3. The drawing loop is executed not in the UI thread but all drawing operations are executed in the UI thread by calling Invoke for each elementary drawing operation. Theoretically, this must be the correct schema! . The downside is that Invoke() is a very expensive call, so it works inappropriately long (see table below). 4. Using memory-stream metafile for buffering. Actually, this is not what I need; in addition, it works even longer then #3. Here is the execution time comparative graph for different implementations of a loop with 2,000,000 drawing lines on my PC. 1. Execution in the UI thread (without DoEvents() calling) - time 00:00:04.6250592 (given as 1) and no "Cancel" available 2. Execution in the UI thread (calling DoEvents() on each step) - 00:00:10.5937500 (2.3 times longer) 3. Execution in a non UI thread (calling Invoke() for each drawing operation) - 00:05:41.560314 (73.8 times longer) 4. Drawing in memory-metafile (no DoEvents() or Invoke() ) - execution time 00:05:06.7153993 (66.3 times longer) Of course, 5 minutes instead of 5 seconds is too much for such a common task (a long loop cancellation). Any suggestions will be deeply appreciated. Alex Tag: TabControl & ComboBox Tag: 53342

    - Error Reading Configuration Settings Hi, I am deploying a project to a laptop. It works fine on my development computer, and I have tested once a few weeks ago. However, this time, the program can not start at all. After some digging, I find that it stops right at the following line (this line is part of the function called by my program's initialization code): -------------------------------------------------------------- //location is a string location = ConfigurationSettings.AppSettings.Get("Location"); -------------------------------------------------------------- Before this line, everything is normal, but program just exit at this line. I can not catch any exceptions at all, and the process just disappears in "Windows Task Manager". Any ideas? Thanks a lot, Guogang Tag: TabControl & ComboBox Tag: 53291

    - Newbie problem Hi, I'm having a problem with a windows application in VB.NET. It is an MDI application, and I have just added a splash screen that is displayed in the beginning of the constructor of the mainform, and then is hidden at the end of the constructor (after all the init is done for the mainform). The splash screen has a background image that fills all the form. There is also 4 labels on top the the background image. The problem is that for some reason, when the splash screen is displayed, the labels are not displayed. In fact, instead they act as if they were transparent, so I see whatever is behind the form on my desktop. Any idea what can I do for this? thanks, Ross . Tag: TabControl & ComboBox Tag: 53287

    - Transparency Problems I am attempting to wrap-up development cycle and have arrived at the point where "small annoyances" can no longer be avoided<g>. I notice that other applications windows (i.e. from other apps) "bleeding through" the UI from time to time. Now the "strange" thing is that the "underneath app" that always "bleeds through" is Internet Explorer. I am at a loss as to how to proceed since I have done nothing "knowingly" to enable any sort of transparency, all TransparencyKey values have been left to their default values.

    - Problem using a textbox to change the data Hello: I have a form that has a dataset that has one table, a command button, and a data-bound textbox. I also have navigation button that navigates through my dataset. When I run the application, I see the row values displayed appropriately. But when I make changes to the value that is dispalyed textbox and click on the Update command button to save the changes, the changes are lost when I refill the dataset. But if I navigate to the privious or next row and then click on the Update button, my changes are saved. Can somebody explain to me what's happening? Here's the code Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load tbxDDLID.DataBindings.Add(New Binding("Text", MyDataSet.Tables("DDL"), "DDL_ID_N")) tbxDDLName.DataBindings.Add(New Binding("Text", MyDataSet.Tables("DDL"), "DDL_Name_C")) End Sub Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click MyDataset.Update() End Sub .

    - Floating window for Office add-in? Hi, I'm developing a Microsoft Word add-in using VB.Net. It contains a custom non-modal dialog box, built from a Windows Form. The form should float above the active document in Word, similar to the behavior of the Find and Replace dialog in Word. In VB.Net, this can be achieved by setting the floating form's Owner property to the lower form: Dim Form as New Form2 Form.Owner = Me Form.Show() However, this doesn't work here since the "owner" is a Microsoft Word window, rather than a .Net Windows Form. Also, I can't just use the .TopMost property for my form, because that will cause it to float above _every_ window on the screen (including other applications.) Is there a way (probably through an API call) to make my form float above the active Microsoft Word document, but not other documents or applications? Thanks, Robert Jacobson Tag: TabControl & ComboBox Tag: 53284

    - TabControl.TabPageCollection property "Item" missing I am developing a form which uses a TabControl. I want the code to be able to detect which TabPage is currently active. The documentation indicates that the TabPageCollection should have an "Item" property which I think may be the way to do this, but the "Item" property doesn't show up on this object in intellisense, and it gives me an error on compile.

    - Detecting Column Data Change without Leaving Row I have a WinForms application that has a master DataSet with related DataTables that various forms reference and bind to. I need to detect when changes are made to the DataSet by a particular form so that the user can choose to cancel or apply thoses changes (the Apply button is only enabled after a change is detected, e.g. after they alter a value and then tab out of the control). So I'm interesting in detecting changes made only to the DataRows that that form's controls bind to for a specific BindingContext. I've got it mostly working with one remaining issue. When there are multiple controls on a form that reference the same DataRow, I have not been able to detect a change to the row (e.g. when the user tabs to the next field) unless the control gaining focus does not reference the same DataRow as the control losing focus. What I've learned from my experimenting with it is that the RowState is not updated until I use EndEdit for the row. However, this only works after the "row loses focus." As long as the next control still binds to the same DataRow the DataRowVersion.Proposed doesn't exist and the EndEdit doesn't do any good. Please advise. Tag: TabControl & ComboBox Tag: 53279

    - Databinding combobox I have a windows form app that is bound to a dataview. If I add a combobox (with the default style of dropdown) and bind its text property to a field then everything is fine. If I now change the DropDownStyle to DropDownList then the binding no longer works (data from the back end SQL doesn't get displayed and if I select something in the combo then the update writes a null value back). I've tried binding to SelectedItem instead but that also doesn't work. Anyone come up with a solution to this one? -- Rob Oldfield www.realuk.co.uk Tag: TabControl & ComboBox Tag: 53272

    - Dataset Update che funziona in modo strano Ciao ho una piccola anomalia, in un dataset. Ho una form di dettaglio collegata con delle textbox a un database sqlserver tramite dataadapter, dopo aver generato il dataset e le stringhe sql per aggiornamenti e selezioni, mi si presenta il prblema. Tramite metodo fill riempio il database, e poi aggiorno tramite il metodo update soltanto che il database viene aggiornato solo se mi sposto al record successivo a quel punto riesco ad aggiornare il database. Mi sposto tramite bindingmanager, è normale che si comporti così. Insomma modifico e se salvo nulla, se mi sposto al record successivo e salvo mi salva il record precedente. Come mai? DaAccessori.update("DsAccessori,"T_Accessori"") e si comporta come vi ho detto mah. Grazie Ciao. Tag: TabControl & ComboBox Tag: 53260

I added the ActiveX control to the toolbox and successfully can add it to any Form I like, just like any other control. When the form the richtextbox is on is the main form of the application it seems to work ok, but as soon as I put it on a dialog's form which is modally shown via Form.ShowDialog() suddenly my dialog's OnLoad-event isn't called anymore !

    - calling a form in a different project How do you instantiate and display a form that is in a different project within the same solution? I have a project full of Crystal Reports and one simple form (clientCrystalViewer) that displays them. It seems like I need to have the Reports in the same project as this clientCrystalViewer form so I can manipulate the dbconnection string dynamically (Its a Crystal issue). Rather than put everyting in one gigantic project (I've got 50 reports so far) I'd rather just call my clientCrystalViewer (really just a dialog box) from my project which holds all the rest of my forms. It seems to me that this should be possible and easy, but I can't find any documentation on it. Any ideas? Thanks Tag: TabControl & ComboBox Tag: 53253

Need to have same ComboxBox in two Tab Pages of a Tab
Control so that both pages would exhibit same behavour for
Combo events.

Modifying the InitializeComponent() to add the combo to
both the pages did not work. However dynamically adding
the Combo to the selected page on
tabControl1_SelectedIndexChanged event worked. Is this the
right approch?

Can I have two seperate combo and sort of set one equal to
the other so that both Combos exhibit same behaviour for
its events with out duplicating the code (event handlers
etc)

Thanks,

You can reset the ComboBox Parent property to be the TabControls SelectedTab
property in the SelectedIndexChnaged event

eg.

Private Sub TabControl_SelectedIndexChanged(byval sender as object, byval e
as EventArgs) Handles TabControl.SelectedIndexChanged
ComboBox.Parent = TabControl.SelectedTab
EndSub
