    - 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: Databinding combobox Tag: 53260

    - CheckBox in DataGrid Hello all. I have place a CheckBox in a DataGrid using the following code: DataColumn dcInclude = new DataColumn("Include?"); dcInclude.DataType = System.Type.GetType ("System.Boolean"); dtParams.Columns.Add(dcInclude); The CheckBox column works and all is good, however, the CheckBox has 3 states. Ticked, un-ticked and grey ticked. Is it possible to have it so that the CheckBox only has 2 states (Ticked and un-ticked)? Thanks people, Jon Tag: Databinding combobox Tag: 53256

    - Help please: RichText Control ActiveX and Load event Please can anyone assist: I try to use the Microsoft Rich Textbox Control 6.0 (SP4) on a winform dialog, since .NET's RichTextBox has problems with legacy components I have to use. 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 ! I verified it by setting a breakpoint in VS.NET and even adding a MessageBox.Show(), but I can't get the OnLoad-Event to fire. Can anyone explain?

    - 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: Databinding combobox Tag: 53253

    - I've fixed my problem. I had a problem with aspnet_wp.exe.I'm a newcomer to Web developement.I've just read first two lessons of: MCAD/MCSD Training Kit: Developing Web Applications with Microsoft Visual Basic .NET and Microsoft Visual C# .NET. I wasn't able to launch my WebForm from VisualStudio.Net Academic because I received: 1) aspnet_wp.exe could not be started. HRESULT for the failure: 80004005;2)aspnet_wp.exe could not be launched because the username and/or password supplied in the processModel section of the config file are invalid. from error log. Then I searched through Newsgroups and found: Subject: Re: Can't access CDO.Message From: "Lion Shi" <lionshi@online.microsoft.com> I must say that I tried only step 1 of recommended remedies below reported: *********************************************** Please try these steps: | > | > 1.

    - DataGrid Q: How to force a column to go muti line if necessary to handle the text I want to have all my columns visible in the window. I've found out how to disable the column resizing, and even to force the horizontal scroll bar to hide itself. What I dont know (if it can be done in the WinForms control) is how to force a cell to go multi line if necessary to show text. I've seen it done in the Web DataGrid. For the edification of everyone, here's how to disable column sizing, and hide the horizontal scroll bar. This, when combined with proper sizing of the columns, puts everthing on the screen for you: Do do any of this you must derive your own DataGrid and override stuff. To make the columns fixed (to prevent the user from increasing their size and necessitating a scroll bar) you must override OnMouseMove and OnMouseDown and stop it from calling the base class when a column resize is being done. To force the scroll bar to hide, hook into the VisibleChanged event and force it to hide there. public class MyDataGrid : System.Windows.Forms.DataGrid { public MyDataGrid() { this.HorizScrollBar.Visible = false; this.HorizScrollBar.VisibleChanged += new EventHandler(HorizScrollBar_VisibleChanged); } protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e) { DataGrid.HitTestInfo hti = this.HitTest(new Point(e.X, e.Y)); if (hti.Type == DataGrid.HitTestType.ColumnResize) { return; //omit base class call } base.OnMouseMove (e); } protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e) { DataGrid.HitTestInfo hti = this.HitTest(new Point(e.X, e.Y)); if (hti.Type == DataGrid.HitTestType.ColumnResize) { return; //omit base class call } base.OnMouseDown (e); } private void HorizScrollBar_VisibleChanged(object sender, EventArgs e) { if(this.HorizScrollBar.Visible == true) { this.HorizScrollBar.Hide(); } } } Tag: Databinding combobox Tag: 53223

    - Events - publish/subscribe and GC'ing In my application the main thread my create several worker threads that will create additional objects. These additional objects become "publishers" and the main thread object (amongst others) then can "register" to receive the events. My question is, what happens when the "publisher" object completes it's work and disappears? Do I need to first broadcast a "please unregister" message to the subscribers? When the publisher goes away, if the subscribers haven't unregistered, will this create a leak and/or prevent the GC from collecting the now demised publisher object? Thanks!

    - Splash Screen 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: Databinding combobox Tag: 53199

    - MDI Problems HI! I've got following problem: I got an app which mainly consists of one main window. There serveral other windows (which I use for settings), but there's also one important data-form. The main windows must not be closed, the other windows must not be modal, they also must not be AlwaysTop and they also are not allowed to become "invisible" (main window covers it, cause of operation in main window (to get information for child window)). So I've choosen to convert my sdi to mdi. My main window is child of another window and should always be maximized. Thats my first problem, cause it doesn't help to cut off the min and max button (resizing through dblclick on title bar) and I can't make my main windows the parent window cause it holds several controls and when I'm showing the child (property/data window), I can't see anything from the child. Most of my property windows are created dynamicly through a database, the size of the window is handled and the Style is set to fixed 3d, but it got maximized. How can I prevent this? I'd be very grateful for your answers Bernhard Tag: Databinding combobox Tag: 53194

    - RowSelect Disabled Datagrid Hi Everybody, I have been trying to create a Datagrid wherein 1) the first row is selected by default when the Form Loads. (Easily done with dg.Select(0)) 2) user cannot tab into any column. ie. unlike the default behaviour which is when the current cell gets focus, the existing text inside it is selected and cursor is at the end of the textbox. I can state it alternatively as "the column should not get focus" 3) When user clicks any other row with mouse or moves in the datagrid using keyboard, the new row shall get selected. For this, i have hooked into CurrentCellChanged event to get the new row and select it. My problem is 1) When user presses Tab in the DG, the focus moves along the columns and which ever column gets focus, the text in it gets selected and text within it gets selected. I have the row selected, but this columns display is not consistent with rest of the columns. 2) As soon as the DG looses focus, the row gets de-selected. For eg. a Messagebox popup and the row gets de-selected. 3) If user presses tab on the last column of the last row, there is no row selected. My dg.select(rownum) has been coded in CurrentCellChanged so, a row shall be always selected. But its not so!!! As an example of what i want to achive is exactly as implemented in TASKVISION sample application provided at http://www.windowsforms.net/Default.aspx?tabindex=7&tabid=44 . I have gone through the source code of this sample and have set the properties of my DG exactly as in the sample, created my TableStyle and GridColumnStyles dynamically. Cant Figure out what to do more. Anybody got ideas/solutions?? Tag: Databinding combobox Tag: 53185

    - Bug in Framework 1.1? I have an application that worked properly in .NET 2002 but doesn't in 2003. It is an MDI application that can have several open forms with some forms being (virtual) parents of others. When a user clicks on a parent form, it attempts to shift the focus back to the child, but this appears to no longer work in the Framework v1.1. As it is an MDI application, I can't use the owner variable to make the parent inaccessible as a form can not be an MDI child and an owner as well. Disabling the parent also does not appear to make it inaccessible. So I have no choice but to call the child forms Show method from the parent's activate event. It runs the code, but it refuses to cause the OnActivate delegate or Activated event in the child form (which it needs to in order to show the children's children). Is this the way it is supposed to work now? Does anyone else have a valid workaround? Any help would be greatly appreciated. Cheers, Dan. Tag: Databinding combobox Tag: 53167

    - What is the best method for creating a "no-touch" client application I have a WinForms application with a config file that I would like to deploy internally by making it available on a central server, where it will be maintained and versioned. I was thinking that accessing it via IE would be helful, but it is not clear how to handle the config file, which does thinks such as activate the client remoting capabibility. I would like changes to this config file to be automatically downloaded with the application. There is also the problem of default permissions. Although this can be handled with isolated storage, it is not clear how I can automatically download any changes to the config file in the central server to this location. Is this approach an acceptable one or is there a better method for accomplishing what I am attempting to accomplish. Tag: Databinding combobox Tag: 53159

    - Animation control and Modal dialogs Hi all. I'm trying a pretty simple thing: show a modal dialog with an animation (AVI file) playing on it. - First problem, I couldn't find any native .net windows form control to do that (at least not part of the original framework) Question: Is there anything simialr in the .net toolbox? - Fine, then I decided to use the good old activeX control "Microsoft Animation Control". I put it in my toolbox then dragged to my form. I wrote the following code: Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load With AxAnimation1 .Open("C:\myfolder\myAnimation.avi") .Play() End With End Sub If I show the form modeless, it works perfectly. But if I show it modally, then the animation does not show up. Questions: * Do I have to do something extra? * Is this a known bug/limitation ? * Can I fix/hack it ? For now I made my form TopMost=True and disabled all the other forms but this is less than ideal for me because it shown in front of all the other applications windows as well. I need it to be the foremost form solely in my application. Thanks a lot. TJ! Tag: Databinding combobox Tag: 53139

    - What is the name for this? Whilst coding away on a DataGrid and ComboBox I noticed the following behavior and want to know a) what it's called and b) what's going on internally within the framework. Basically, I did the normal SqlConnection, SqlDataAdapter and DataSet creation for a single table in the Northwind database. I set the DataSource properties of each control to the DataSet then filled it with the SqlDataAdapter during startup. When the form runs, the DataGrid displays the table and the ComboBox displays a corresponding list of product names (ProductName column). So far so good. Now, I haven't added any event handlers for anything. When I select a new product from the ComboBox, the DataGrid will move its selction arrow (that thingy on the left side, whatever its called). Furthermore, if I click on a cell within a row in the DataGrid, the ComboBox will automatically select the correct ProductName from its list of items. In other words, by using the DataSet for 2 different controls they somehow get linked and respond to each other's events. This is pretty cool and came for free. So, what is this behavior called so I can investigate a little further? Is it something to do with BindingContext's? How does the framework connect these 2 and how do they talk to each other (I'm assuming events but how does that connection get made?). Hope someone has an answer.

    - Exceptions not getting propagated across forms. Hi All, Our application is a Windows Forms application on .NET Framework 1.1. We are having the following scenario: 2 Windows forms - Form1 and Form2. On click of a button in the Form1, Form2 is loaded. Now, if an exception is raised in the Form2's load event, it is caught in the try-catch block of the Form2's Load method. When we throw the caught Exception, we expected it to propagate to the calling form (Form1) and get caught there. If we do an F5 (Step-in), the exception raised in Form2 is getting properly propagated to the Form1. But, when I do a CTRL-F5 (run without debug), the exception is not getting propagated to the Form1, The exception is not is getting propagated in the release mode too. Could not understand why this is happening. Is it any know bug in .NET 1.1. Any pointers to a solution for this would be greatly appreciated.

    - Inheriting Windows Control as Abstract Class Hi, we'd like to define an abstract library class for a windows control, where we specify a couple of abstract methods in order that they must be overridden and implemented differently in each derived class. We've tried creating the base abstract class and the derived class in the main project but this leads to the following error appearing in the designer view of the derived class: "The designer must create an instance of "IamsPack.ctlIamsPackBase" but it can't because the type is declared as abstract" The funny thing is that the designer view displays fine when we first open the solution, and then gives an error after we've run the application from within Visual Studio. I've read in another post that it's more stable to create the base class in a separate library DLL and then add a reference in the main project. But before I do that I'd like confirmation whether there is any problem with making the base class abstract. Any feedback/suggestions would be greatly appreciated.

Thanks for any help Tag: Databinding combobox Tag: 53108

    - Dynamic Sockets Settings I need to be able to do the following and I'm not sure if it can be done, or how to do it. Socket A will send a request to Socket B which will be listening. Depending on the info received, Socket B will then forward the request to a Socket C or a Socket D. Socket B must then wait for a response from Socket C or D, and then respond to Socket A. Question: Can Socket B dynamically listen and redirect requests to a different IPs depending on the received message. If so, an example or reference will be greatly appreciated.

    - setfocus in vb.net? Hello friends. Vb6 had setfocus(). What is it in vb.net? Thanks Denis Tag: Databinding combobox Tag: 53099

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?
