    - Problem: HowTo update UI from workerThread? Hi! I want to update an userinterface from a background thread. I think that a good way to do this is to use to use methodinvoker in UI-thread and then begininvoke in workerThread to pass parameters back and update the UI. But i have one question. The Method i start with begininvoke is a public sub on another class (not the UI-class). Do I have to pass the form (like a reference) to the other class which the workerthread uses to be able to use it´s begininvoke method? Is this a good way to do this. Here is my code: Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " ' Some code Me.Label1 = New System.Windows.Forms.Label ' Some more code #End Region Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim workerThread As New MyWorkerClass Dim mi As MethodInvoker = New MethodInvoker(AddressOf workerThread.StartWork) mi.BeginInvoke(Nothing, Nothing) End Sub Public Sub UpdateLabel(ByVal o As Object, ByVal e As System.EventArgs) Dim myEvent As MyLabelEvent = CType(e, MyLabelEvent) Label1.Text = e.LabelText() End Sub End Class Public Class MyWorkerClass Public Sub StartWork() Dim e As System.EventArgs While True e = New MyLabelEvent("Text on label") Dim lst As Object() = {Me, e} ???.BeginInvoke(New System.EventHandler(AddressOf ???.UpdateLabel), lst) DoSomeWork() End While End Sub Public Sub DoSomeWork() End Sub End Class Public Class MyLabelEvent Inherits System.EventArgs Private _labelText As String Public Sub New(ByVal label As String) MyBase.New() _labelText = label End Sub Public Property LabelText() As String Get Return _labelText End Get Set(ByVal Value As String) _labelText = Value End Set End Property End Class Best Regards / Steve Tag: Change Cursor over ActiveX control Tag: 73637

    - Microsoft Application Block pattern Long shot but here goes..... I am developing a vb.net application using the MS application block pattern, available @ http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag/html/uipab-ch03.asp And I have developed some views that derive of Microsoft.ApplicationBlocks.UIProcess.WindowsFormView BUT I am unable to get any key press events, I want to stop the user pressing the Alt+F4 key to close the application, I can do this in a normal application very easily so don't bother replying with a simple example, what I want to know is why I'm not getting the events when using the application block patterm? the application block is written in C# and I have tried overriding the the KeyDown method in the application block but don't get any event being caught there either. Anyone got any ideas? Cheers for any help in advance Ollie any example class is shown below.... Public Class Welcome Inherits Microsoft.ApplicationBlocks.UIProcess.WindowsFormView .... .... .... Protected Overrides Sub OnKeyDown(ByVal e As KeyEventArgs) If e.KeyCode = Keys.Alt Then ErrorHandler.ProcessError("ALT PRESSED") Else MyBase.OnKeyDown(e) End If End Sub Tag: Change Cursor over ActiveX control Tag: 73636

    - TabControl - change the tab shapes and appearances? I have tried without success (using C#) to change the standard rectangular tabs (for the TabPages) to look like the ones in Messenger - funky curved jobs. However whenever I try to overwrite an existing tab, either by superimposing a bitmap over it, or by manually drawing a new shape with the Graphics methods, the standard rectangular tab outline always shows through. I captured both the DrawItem and Paint events. I saw a partial solution in Code Project, which used a wrapper DLL around UxThemes.dll, but this involves installing this extra DLL with my product. And I couldn't get it to work anyway! It seems this is a known problem in .NET. A colleague using C++/MFC had no trouble doing this. Any suggestions? - please!

    - Big picture question - Custom control concepts Maybe it's just late but I'm having some trouble with custom control concepts. Do I understand this correctly? If you define a custom control, you are responsible for defining all events and properties, even if it inherits from an existing control that has the events you want?

    - Disposed forms problem I have a simple problem: In calling form: Private _theForm As MyFormClass() ' in a button click event... If theForm Is Nothing Then theForm = New MyFormClass() End If theForm.Show() The problem is if I close theFrom, then click the button of the calling form again, theForm Is Nothing will evaluate to False (meaning it's a valid reference), yet when theForm.Show() executes, I get an exception "Cannot access disposed object named 'theForm'" Even if I call Dispose on the called form when it's closed, the problem doesn't go away. I thought it was just some garbage collection issue but calling GC.Collect/WaitForPendingFinalizers before theForm.Show() does not make any difference. As a workaround, I could trap the exception in a try block but I was hoping for a more elegant solution, like simply inspecting a property. In the first place, why does theForm Is Nothing evalute to False when the form is already closed/disposed? Many thanks =) Tag: Change Cursor over ActiveX control Tag: 73610

    - Data Conversion in a grid I have a custom grid control and I'm stuck on an issue in the data binding. Using a method similar to the DataGridColumnStyles class, I have a column style class that allows you to map the bound datasource fields to the grid columns. I've added a Format property which will take a format string such as "{0:C}" which will then convert the underlying data to a currency string. This works very nicely. The problem is when the user goes in and edits data. Let's say that a column has the above currency format string and the data in the cell is $4.45 If the user changes the value, I need to then update the data source. I need to handle the situation where the user puts in either $4.50 or 4.50 and be able to properly convert it back to the underlying type. Is there an easy way to do this without doing a huge case statement for all the different data types? The underlying data can, of course, be of any type. In the grid it's represented as a string. All I have is the format string to know about formatting. I'd rather not have to parse the format string to figure out how to parse the underlying data. Is there some way I can use it to do the parsing? Thanks. Pete Tag: Change Cursor over ActiveX control Tag: 73607

    - Convert Access application to .NET? I have a small-medium sized Access application that is poorly written. My choices are to either rewrite large parts of the Access app so that it functions reasonably well, or to convert the whole thing to .NET. Not being an Access developer, the .NET approach seems most natural, but I want to do the right thing for the client (even if I end up giving away the contract). I posted on the Access forum and got the impression that my fears about Access being an unstable piece of junk were unfounded, and that most of the things that need to be done in this type of application could be done quickly and easily in Access and the rest could be coded as one would do in any other environment (just have to give up the "free" things that Access provides). Does anyone have any experience with this type of conversion? I would be interested in your thoughts. Alfredo Tag: Change Cursor over ActiveX control Tag: 73602

    - Complex properties in custom controls I have a control, let's call it MyControl. One of the properties of MyControl is MyControlStyle. MyControlStyle is a class with a number of properties. MyControl always has a valid instance of MyControlStyle (it is instantiated in the field declaration). In the property grid, I want to lay out the items in MyControlStyle when someone selects a MyControl on the form. They are all simple data types and don't require any sort of custom designers or anything in themselves. How do I get the properties of MyControlStyle to show up in the property grid without duplicating the properties in MyControl. I mean, if I have to pass the properties through like that then it's kind of pointless to have the MyControlStyle class separate. Thanks. Pete Tag: Change Cursor over ActiveX control Tag: 73585

    - WinForms, Events, and Subscribers Background -------------------------- I am in the process of creating a WinForms app with many forms. I have a set of forms that all subscribe to events on a custom object. When the forms are created I manually create a subscription in the form to one or more events in the custom object. (BTW, this is the same design pattern used by IssueVision discussed at DevDays). I have a controller form (MDI parent) that determines which child form is currently being viewed. When a new child form is selected, the current child form is manually closed [using Form.Close()] and disposed [using Form.Dispose()] and then the new form is shown. This keeps only one child form open at a time. Question -------------------------- Even after child forms are closed and disposed, when events are raised from the custom object, the events are still triggered in the disposed child forms. Could someone explain why this is happenning? I must be misunderstanding something. Do the child forms need to manually unsubscribe from the events in the Closing event? Is there a better place to do this? TIA, Doug Tag: Change Cursor over ActiveX control Tag: 73583

    - Need advice on making a MessageBox replacement I'm looking to make an enhanced MessageBox. I want to make it work very much like the regular MessageBox as far as developers are concerned, so I'd like to use the Show() method to display it. However, I want it displayed modally, which we normally achieve with ShowDialog(). Is there a way that the called form can force itself to display modally, or can you think of another way I can do this? Another question I have is about icons. I want to pass a standard MessageBoxIcon enum to the Show() method and then display the OS-specific icon that was requested. In other words, it'll look different on XP than on 2000. To this end I can't simply stick a graphic in my assembly. I can probably figure out how to DRAW the icon myself, it's RETRIEVING it from the system that's beyond me right now. Suggestions?

    - DataGrid Refresh problem I have a data grid refresh problem. I have a few columns and the first column is data in the form of numbers. And in the form of the data grid if I specify for example something like a code(in a text box) the column of numbers should change colors depending on whether the number was in the specified code(if it belongs to the code, color the cell (first column) in Red and if not in some other color). It all works out fine until I scroll up/down and trigger the paint event. The changed colurs seem to be changed. I want the refreshing to be done for all records for that column, but it seems it only refreshes parts of the datagrid. How do I make the refreshing to be done to the whole datagrid rather than a part of it, so I can get the original colur change for each cell of the first column. Code //method to be passed into the coloumn style that determines the color public Color MyGetColorRowCol(int row, int col) { // just conditionally set colors based on row, col values... short number = 0; short retval = 0; Color c = Color.PaleGoldenrod; if (col == 0) { number = array[cIndex]; retval = GetIfInChannelOrNot(code, number); if(retval==0) { c = Color.LightGreen; } if(retval!=0) { c = Color.Red; } cIndex++; if(TotalNumbers == cIndex) { cIndex = 0; } } else { c = Color.LightGray; } return c; } //delegate required by custom column style public delegate Color delegateGetColorRowCol(int row, int col); public class DataGridColoredTextBoxColumn : DataGridTextBoxColumn { private delegateGetColorRowCol _getColorRowCol; private int _column; public DataGridColoredTextBoxColumn(delegateGetColorRowCol getcolorRowCol, int column) { _getColorRowCol = getcolorRowCol; _column = column; } protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight) { // the idea is to conditionally set the foreBrush and/or backbrush // depending upon some crireria on the cell value // Here, we use a delegate to retrieve the color try { backBrush = new SolidBrush(_getColorRowCol(rowNum, this._column)); foreBrush = new SolidBrush(Color.Black); } catch(Exception ex){ /* empty catch */ } finally { // make sure the base class gets called to do the drawing with // the possibly changed brushes base.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight); } } } Tag: Change Cursor over ActiveX control Tag: 73540

    - Displaying cells in the DataGrid with their original formatting Hi, I've noticed an unexpected behavior with the DataGrid control. Cells that have special formatting only display their special formatting (such as diferrent bg color, text wrap etc.) when the user clicks on them. Is there a way to somehow make the datagrid display the all cells in their original formatting automatically, rather than only when clicking on them? I'm mostly interested in this behavior because i want the cells that span over more than one line to wrap text. I've already found a way to change the rows' height (using the help of the incredible SyncFusion site!), so i thought it would be nice to also have text wrapping in the cells when the height is right. I wonder if it can be done using reflection, because i didn't see any public or prortected properties for changing this behavior.

I have set KeyPreview=true and the delegate is called correctly whenever I press a key, except if the active control on that form is a DropDown ComboBox. If I change that ComboBox to be DropDownStyle=ComboBoxStyle.DropDowList the delegate fires when I press a key in that control, as I would expect. The problem is I don't want to restrict the ComboBox to a fixed list of options. The user needs to be able to select, or type their own option. I have reproduced this in an extremely trivial app - one form, two comboboxes, one delegate, and no databinding etc. Does anyone know whether I could be doing something else that has created this problem, or whether this is a known bug? I have searched but can't find a post that seems relevant. Thanks, Scott. Tag: Change Cursor over ActiveX control Tag: 73501

    - Empty value in binded combo box Hi all. I have to display a dialog adding a new DataRow into the DataTable (say, dtMain). One field (say, "Location") of dtMain is a reference to the "ID" field of the other table (say, dtLocations) and I want this field to be shown on the dialog form as a list of values of all "Name" fields of dtLocations, not as a list of "ID" numbers. I bind as follows: // Making referenced data displayable by their names dlgEditor.comboBoxLocation.DataSource = dtLocations; dlgEditor.comboBoxLocation.DisplayMember = "Name"; dlgEditor.comboBoxLocation.ValueMember = "ID"; The other requirement is that initially I have to display the empty Location field on the dialog form. dtLocations does not contain a row with empty "Name" value. Of course, I would be glad to do dlgEditor.comboBoxLocation.SelectedValue = "" or something like this but I get a natural exception. This is what I do. Before I show the adding dialog form, I add the temporary DataRow into dtLocations with empty "Name" field: DataRow rowWithEmpty = dtLocations.NewRow(); dtLocations.Rows.Add(rowWithEmpty); dlgEditor.comboBoxLocation.SelectedValue = DBNull.Value; // or "" Then I show the dialog, everything looks fine. After the dialog isclosed, I delete this temporary row from the dtLocations: dtLocations.Rows.Remove(rowWithEmpty); This works (the only thing I don't like is that this temporary empty value is available among combo box values) but I am not sure I did what I had to do in this situation (I am a newcommwr in .NET). Is there any smarter decision? Thanks, Dmytro Pavlov. Tag: Change Cursor over ActiveX control Tag: 73497

    - Best Place To Store Personal Information Hi to All, I'm developing an application in VB .NET. I have a question: what is the best place to save personal settings of my users? I mean, when a user uses my application, it can create a personal profile (e.g. last files opened, custom settings, etc...). What is the best place to save them? At first, I thought to save them in the registry, in the CURRENT_USER section, but I'm not sure every user can have read/write access to it. What do you suggest? Where can I find more information? Thanks, Marco Tag: Change Cursor over ActiveX control Tag: 73496

Hello,

I am trying to build a form that can display HTML content in the background
and various controls in the foreground. I am able to achieve this using the
WebBrowser activex and adding foreground controls to the form. So far
everything is ok. My problem is that I want to control the Cursor over the
controls and the background. Since the WebBroser (my background) is an
activex, I cannot control it's cursor!

I had also problems in this configuration with mouse events, but thanks to
you guys that one is now solved with IMessageFilter.

So my question is: How can I control the cursor shape over an ActiveX
control?

Thanks
