    - need help in hosting UserControl in IE Hello developers! I`ve created an assembly and I host a UserControl-derived class from it in IE using <object> tag. Like this: <object id="upload1" classid="Foo.dll#BarCompany.Foo" width="1000" height="500"> <param name="xxxx" value="yyyy"> </object> And everything works. However, when I strong-name this assembly this BarCompany.Foo control is not loaded, and IE shows an image placeholder. Maybe there`s a special classid value for this case or something I missed? Thank you for advices and help! Tag: Application Icon Tag: 80120

    - Sending Mail from a WinForms client I'm wanting to include in my WinForms app the ability to send an email. Is it possible, and what is method to take, to send email from within a forms app, ideally using the user's mail account. What I would like to avoid is having to setup special mail servers/SMTP servers. If their Outlook Express client can send mail, can I a stuff message through that connection? Currently if I do this: Dim msg As New MailMessage With msg .To = "name@domain.com" .From = "My App" .Subject = "My Subject" .Body = "My Body" .BodyFormat = MailFormat.Text End With SmtpMail.SmtpServer = "MachineName" SmtpMail.Send(msg) ....I get a Could not access 'CDO.Message' object. error.

    - hWnd question... I am not sure that I understand what the Control.Handle value represents. The MSDN documentation say that it is "the window handle that the control is bound to." Does this mean that the handle is for the control itself or for the control's parent form? I am trying to call a Win32 API metohd that will set the scroll position of UserControl. The method requires an hWnd, and I am wondering if the control's base.Handle would give me that value. Any insight would be appreciated. Thanks! Tag: Application Icon Tag: 80070

    - DataGrid ReadOnly Column BUG ! I´ve found a weird behaviour in the DataGrid: Scenario: ---------- I use a TableStyle with several standard TextBoxColumns within. One of that columns have the ReadOnly property set to true. In execution, select the text or a part of it in a cell inside the ReadOnly column. Then, do something that force the DataGrid to loose the focus and afterwards something else that changes its contents (DataSource changed, parent datagrid´s selected row changed, whatever...) After that, the text of the cell you selected is not refreshed, so it still appears in the DataGrid, even if all the rows of the DataGrid disappeared, the text is still there, by itself, looking at me and laughing. The text is refreshed if you give focus to the DataGrid again (by clicking on it or by manually calling .Focus() ). Im afraid I´m not using the correct terms to to search in the groups couse I couldn´t find much about the issue. I think it´s important enough to fix this, you guys out there ;) Thanks in advance.

    - searching in a listbox explorer style Hi If you have multiple items in a listbox, click into the listbox, then type for instante the letter "p", the first item whose text property starts with "p" will be selected. Pressing "p" again will jump to the next item starting with "p", etc. In Windows explorer, you can type multiple letters after each other, and if you're fast enough, they'll be taken as a search term together. For instance pressing "p" then "e" then "a" would lead to the first folder/file whose name starts with "pea" being selected. Is there any way to achieve this functionality in a Listbox as well?

    - OpenFileDialog and DataSet WriteXML strange problem Hi, I have a very strange problem which i hope someone can help shed light on. I have a Windows Forms application which provides data-entry UI. Data inputted is then stored into a DataSet which will be persisted into a XML file using the WriteXML method. The Dataset which contains a Filename data column (type = string); A user selects a file using the OpenFileDialog component. The file name is displayed in a textbox until the user clicks on the Save button. PROBLEM: If the file is selected using the OpenFileDialog.ShowDialog() method, the file name is added to the dataset, but it is not written to the XML file. However, if the filename is manually typed into the textbox, saving to XML file succeeds. Further tests shows that this problem only shows up in WinXP system. Machines running 2000 saves the XML file just fine. In the event of failure, no exceptions nor errors are shown. This is a very strange problem, any help will be very much appreciated!

    - Refresh current form to reflect culture change Hi everybody, I want to add localization support into my windows forms application. Basically, I create a menu item where users can choose a language of their choice. When users choose their preferred language, I want to update all the texts/labels on the current form UI to the new culture, instantaneously. For this, I have created a .resx file for each supported culture and in the event handlers for menu item's Click event, I change the CurrentUICulture property to the corresponding culture as follow: System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-US"); However, when the program runs, nothing happens. So, I guess I must somehow force the form to reload itself. I've tried all the methods like Form.Update(), Form.Refresh(), Form.Invalidate(), ... but unsuccessful so far. Does anybody know the solution to this scenario ? Thanks a lot SuperKinhLuan Tag: Application Icon Tag: 80028

    - Panel controls autoscroll not working I have been having problems with a panel control since installing Windows XP SP2 and .Net framework 1.1 sp1. I have several forms in an application which contains several panels. One of the panels contains a panel which has controls added to it at runtime with the autoscroll property set to true. Some of the controls added are outside the visible range of the panel. Before the service packs the panel would have a scroll bar. Also when a child control outside of the visible range gained focus, the panel would autoscroll so that the control was visible. After the service packs, the panel scroll bar will not show up for controls added during runtime. If I add a control at design time outside the visible range of the panel, the scroll bar will appear. However, when the control gains focus the panel autoscroll position go to 0 instead of what is necessary to keep the active control in view. Has anyone had similar problems and/or know how to fix this problem? Thank you in advance. Tag: Application Icon Tag: 80011

    - Inherit ListView Column Header Hi All, I have been looking at this for a little while now and can't figure it out. I was hoping someone could help. I needed to have an aditional property for the ColumnHeader object contained in the ListView Columns collection. I needed this property to map ListView columns to DataTable columns for a suedo databinding function. I though perhaps inherit from the listview and ColumnHeader objects. Here are the steps and code: STEP 1: Create a ColumnHeader object that inherits from ColumnHeader with the additional property Public Class DataBoundColumnHeader Inherits ColumnHeader Private m_BoundColumn As String 'new property Public Sub New() MyBase.New() End Sub <Category("Data")> _ Public Property BoundColumn() As String Get Return Me.m_BoundColumn End Get Set(ByVal Value As String) Me.m_BoundColumn = Value End Set End Property End Class STEP 2: Create a ColumnHeaderCollection object that inherits from ColumnHeaderCollection and shadows functions which assign and retrieve my custom DataBoundColumnHeader object Public Class DataBoundColumnHeaderCollection Inherits ListView.ColumnHeaderCollection Public Sub New(ByVal Owner As ListView) MyBase.New(Owner) End Sub Default Public Shadows ReadOnly Property Item(ByVal Index As Integer) As DataBoundColumnHeader Get Return CType(MyBase.Item(Index), DataBoundColumnHeader) End Get End Property Public Shadows Function Add(ByVal Column As DataBoundColumnHeader) As Integer Return MyBase.Add(Column) End Function Public Shadows Function Add(ByVal Text As String, ByVal width As Integer, _ ByVal TextAlign As HorizontalAlignment) As DataBoundColumnHeader Return CType(MyBase.Add(Text, width, TextAlign), DataBoundColumnHeader) End Function 'This should be public: but a conversion type error occurs Private Shadows Sub AddRange(ByVal Values() As DataBoundColumnHeader) MyBase.AddRange(Values) End Sub End Class STEP 3: Create a ListView object that inherits from ListView shadowing the Columns property to accept my ColumnHeaderCollection Public Class DataBoundListView Inherits System.Windows.Forms.ListView Private m_DataBoundColumns As New DataBoundColumnHeaderCollection(Me) <Category("Behavior"), _ DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public Shadows ReadOnly Property Columns() As DataBoundColumnHeaderCollection Get Return m_DataBoundColumns End Get End Property End Class THE PROBLEM: PROBLEM 1: This will not work unless the shadowed function AddRange is private and not public: The error is a typeconversion error PROBLEM 2: When I add the DataBoundListViewControl to a form and add some columns I get the following automatically generated code: 'Notice the System.Windows.Forms.ColumnHeader object Me.DataBoundListView1.Columns.AddRange(New System.Windows.Forms.ColumnHeader() {Me.DataBoundColumnHeader9, Me.DataBoundColumnHeader10}) Me.DataBoundListView1.Location = New System.Drawing.Point(72, 104) Me.DataBoundListView1.Name = "DataBoundListView1" Me.DataBoundListView1.TabIndex = 0 Me.DataBoundListView1.View = System.Windows.Forms.View.Details The automatic code generator creates an array of new ColumnHeader objects but assigns DataBoundColumnHeader ojects to items in that array. This is a little confusing. I really prefer it creates an array of DataBoundColumnHeader objects and then I could make my Private AddRange, Public.

    - Disappearing Window in Word Addin I am developing an addin for Word using C#. When the addin is activated, an always-on-top window is created with which the user interacts while editing a document. Sometimes, this window disappears. That is, you can no longer see the window, but it still exists. I have checked this through the debugger. The Visible property is still set to true, the size does not change, etc, but you can no longer see/interact with the window. The window disappears after closing a MessageBox that was created by the addin, but not always in the same place. This behavior occurs on Windows 2000 or Windows 2000 Server systems with Office 2000 installed. It does not occur on Windows 2000 or Windows XP systems with Office 2003 installed. Does this behavior sound familiar to anyone? Any help would be greatly appreciated. Tag: Application Icon Tag: 80005

I've created a connection by dragging a SQLdataAdapter on to the form and using the Wizard with no special conditions. (Just select * from a single table.) I've bound a few textboxes to the fields (4 boxes and a DateTimePicker to be exact). I fill the dataset on form load and I know I'm getting data then. My problem is this: Nothing I do will create a new row. I'm trying to add a record with what I thought were the usual means. Me.BindingContext(Me.DataSet31, "OrderH").EndCurrentEdit() Me.BindingContext(Me.DataSet31, "OrderH").AddNew() (The number of rows in the table does not increase and when I go to the Update call there is no row with DataRowState = Added.)

    - Having derived forms recognizing the docking property of objects in the base form I have a base form where I docked a panel control across the header to act as a custom menu/tool bar. If I were to dock another control in the base form to the left side, it would recognize the first panel docked on the header, and therefore the 2nd panel would stretch from the bottom of the form to bottom of the 1st panel (1st panel being the one docked to the top which stretches from the left to the right side of the form). Ok that all works as expected. now I remove the 2nd panel from the base form as it was just a test to see that the docking was working correctly. Now I build the project and go to a form that's derived from this base form and I dock a control to the left side of the form. Instead of this left-docked control stretching from the bottom of the header panel (which is part of the base form and docked on top) to the bottom of the form, it stretches all the way to the top of the form and overlays my custom header (which is part of the base form). Is there anyway to change this behavior for a control docking in a derived form and recognizing the docking of a control in the base form? Thanks. -- moondaddy@nospam.com Tag: Application Icon Tag: 79983

    - How to change the backcolor of a MDI form I'm writing an app in vb.net 1.1 and need to change the backcolor of an MDI form. I saw in another posting in this user group which referred to a link <URL:http://vbaccelerator.com/article.asp?id=4306> which had a good example, however, it was in C# and I wasn't able to get through it. Can anyone refer a good vb example? Thanks. -- moondaddy@nospam.com Tag: Application Icon Tag: 79981

    - VB.NET Application on File Share Cannot Be Updated I have a VB.NET application that I have deployed via UNC file share. Everything works fine after the users run the small MSI that sets the appropriate trust level for the URL. The problem I am running into, however, is that I cannot push updates out to the server. When I attempt to copy a newer version of an assembly, I get a File Sharing Violation error. What gives? I thought (and verified) that the EXE is downloaded and run in a local process on the user's machine? When I look in task manager on my machine, the application shows up (it does not on the server with the file share). I used ProcessExplorer on the server, and it seems that there are 3 references and 1 handle to each of the assemblies that comprise the application. Doesn't matter how many users are currently running the application. It always shows 3 references and 1 handle. Again, this makes no sense to me and my understanding of how NTD is supposed to work. Maybe my understanding is wrong? I have read everything I could find on deploying applications via file share, and I have not seen anything about problems copying updated assemblies out to the share. Any insight that anyone might have is greatly appreciated. I have some critical updates that I need to get moved out as soon as possible. Thanks, Ken Tag: Application Icon Tag: 79979

    - numeric up down control - whidbey if I manually delete the value in the text box in a numeric up down control, the Value property does not change, and following this, programmatic changes to the Value property do not get reflected in the UI although the property does actually get set. Has anyone else experienced this problem? Can anyone give me any ideas as to how I can get around this. Or is it just a bug with Whidbey? Thanks Jag Tag: Application Icon Tag: 79977

    - How to yield the primary thread to some other task? Hi, I'm trying to create a method on my windows form that starts a multi-threaded task, waits for it to finish, and then returns. To be more precise: the form has a LoadUrl() method. This method calls the Navigate() method on the form's embedded WebBrowser control, and then does a WaitOne() on a ManualResetEvent. This ManualResetEvent will be Set() from WebBrowser's DocumentComplete handler when loading is done. So, what happens is this: when Navigate() is called, the web browser starts the download in a secondary thread and returns, thus jumping to my WaitOne() call where I wait for it to finish. While downloading, the browser wants to update the UI, which has to be done from the primary thread. But no dice, the WaitOne() call is blocking it. Now, I must do some kind of Wait() on the primary thread because I want to return from the method only when the operation is complete. But, I somehow have to wait without blocking this thread. Is this possible? It seems that the windows form has a solution to this. How does the form manage this primary thread so it knows how to do BeginInvoke, for example? Do I need to use the message loop or something? Any hint is welcome. Thanks in advance! -- Boris Drajer <boris.drajer@do.not.s.p.a.m.micro-bs.com> Tag: Application Icon Tag: 79976

seems like a really simple question after some of the things I've managed to
do but...how do I set up my application so that it has a custom icon rather
than the windows explorer .exe standard icon?

The icon that I want to use is a BMP format picture at the moment.

Can anyone help???

Many thanks

James

Hi James,

I believe you need to convert it to an icon file (.ico) before you can use
it. Typically you need three formats, 16x16, 32x32, 48x48 pixels.

The icon you see in explorer can be set using /win32icon compiler option or
specified in the project options in solution explorer in Visual Studio .NET

Happy Coding!

You can do that in the project properties dialog.

The icon needs to be in the icon file format. VS.NET can be used to create
icon files (".ico").
