    - NotifyIcon remains after abnormal termination Hello - the NotifyIcon for my application remains in the system tray if the application is abnormally terminated. Is there anyway I can clean this up - either by the application (NotifyIcon.Dispose() doesn't help) or by another application that could force a repaint/repopulation of the system tray? A litle bit more background. I have written an application which, when run with certain command line arguments, will kill other instances of itself. Unfortunately, it does leave the NotifyIcons visible. Thanks very much for you help Lee Tag: Chocolate IDE for .NET Tag: 54903

    - Odd behavior with ActiveX control on a Windows Form Hi When putting a VB6 built ActiveX control on a Windows Form you get several troubles concerning focus in that form. First of all the Enter and Leave events for the ActiveX control only fires once. Then if you got a button on the form that lies directly on the Windows Form and presses this, it gets the "Acceptbutton" shade and whenever you press Enter it will be clicked. This is OK, but when you set focus on the ActiveX control again, the "AcceptButton" shade will not disappear. While having focus on the ActiveX control, any subsequent keypresses on the Enter-key will fire the click- event on that button and make the user very confused about what happened. Is there something you could do when writing that VB6 ActiveX control to avoid this behavior, or is this a general bug concerning all ActiveX controls being placed on Windows Forms? Please let me know if you've got the answer! /Patrik Karlsson Tag: Chocolate IDE for .NET Tag: 54896

    - TextChanged event firing before the KeyXXX events Hi all, I have a combobox control, in wich I put an autocomplete code. This code is in the TextChanged event, but when this event fires, the Text property isn't updated yet. For example, if the Text property is "Foo" and I press the letter "d", the Text property when the TextChanged event runs is "Foo". Only after the TextChanged event be processed, the KeyDown, KeyUp and KeyPress events fires and update the Text property. I think it's very strange. Is it a bug? How can I get the correct Text property in the TextChanged event? Thanks in advance, Fabrício de Novaes Kucinskis. Tag: Chocolate IDE for .NET Tag: 54890

    - Keep WinForm open on own thread Hi, I have a situation where I have a sub that is started on its own thread. The sub opens a form which is supposed to stay open, and it does open for a brief flash, but as soon as the sub ends, the form goes away. This behavior makes sense to me, but I'm wondering how I can keep the form open until the user is done filling it in, then close the form and abort the thread.

    - Pasting metafile from clipboard into picturebox control Hi, I am currently writing some code which copies an image in the Windows metafile format pasted on the clipboard into a picturebox control. For some reason, I have not been able to get the following code to work: Dim od As IDataObject = Clipboard.GetDataObject() If (od.GetDataPresent(DataFormats.MetafilePict)) Then PictureBox1.Image = CType(od.GetData (DataFormats.MetafilePict, True), Metafile) End If When I switch the formats to Bitmap, everything works fine, but when I use the EnhanceMetafile or the MetafilePict formats, I get a blank picturebox. I have been reading on the net about how there is a bug in the framework with regards to metafile formats on the clipboard but I don't know enough about the native API calls to make heads or tails of it. Any help would be appreciated. Victor Tag: Chocolate IDE for .NET Tag: 54884

    - Problem placing components on inherited forms Hello, I am trying to create a custom control which inherits from System.Windows.Forms.Form and can be used as a base class for an application. So far so good. I am also writing custom components which inherit from System.ComponentModel.Component. What I would like to know is if there is any way for my custom form class can be made aware of these components? The problem is that when my form class is instantiated at design time via "Add Inherited Form" and I drop a component on this form, the designer automagically extends the base class by adding an IContainer called "components". The component is then added to this collection. Is there any reasonably simple way to get these components to act like controls and drop themselves into a nice collection of my choosing? I also need the reverse link - from component to form i.e. something comparable to the Parent property of controls. Thanks for all help. Sincerely, Markus PS - for more background info, I started a thread on Aug. 19th '03 re: "How-to create user control replacing..." Tag: Chocolate IDE for .NET Tag: 54883

    - newbie C# Clicked event not firing Hi All, In a C# Windows project, My clicked event code did not fire. First I had to actaully declare the method rather than just adding the code and then in the InitializeComponent I had to add: this.button1.Click += new System.EventHandler (button1_Click); So that the event would run. In vb.net this seems to be generated automatically. Do I have a setting turned off somewhere in Visual Studio? tia Randy Tag: Chocolate IDE for .NET Tag: 54864

    - SIMPLE question. Hello all - I have 2 VB.Net Win forms. When I'm through with using Form #2, I just close it but what I want is trigger an update event on Form #1 based on the activity inserts I just did in Form #2. Is there an event that I can call with the form being open already like frm1.<combo box>.focus so I can trigger the update event. I realize this a simple question but during the converting to .Net idea, I don't want to create a new instance of that form. So even a gotfocus or focus to the form itself would be great. And any code of how that is constructed. Much thanks and cheers! Mark Tag: Chocolate IDE for .NET Tag: 54852

    - Managing two connected forms Hi all, in my application I need to show a form that contains text box where user can edit patterns. When text in the text box changes, second form displaying the list of items matching the current pattern is shown. The problem is that I would like the first form to hide when focus is moved to some other window _except_ for the second form. I.e., user should have an opportunity to edit the pattern in the text box and select items from the list at the same time, but when it moves focus away both forms should disappear.

    - custom drawing menu and MdiList I have a nice custom drawing menu. One of the items is a MdiList and dynamically shows the list of all open MdiChildren. the problem is that the items that identify the mdichildren are not custom drawn. I have no idea how it could be possible to perform also custom drawing for these items. at first glance this does not look like a big problem. after all, the subitems could be drawn as standard menu items. but here comes the the additional problem - the main menu item that has the MdiList item as the subitem is incorrectly drawn because it gets sligthly wrong information about its Bounds (in DrawItemEventArgs).

    - Problems in Connection pooling: Urgent Hello All, My windows application has a form that needs to display fresh data to the user at short intervals (say every 10 seconds). For this purpose, I have included a timer. On every timer tick, I perform the database related operations to display the result to the user. Note: Multiple instances of my application will be running at the same time and hence the timer running in each instance and initiation database operations. With this approach, I started receiving errors like: Connection timed out. The connection pool has reached its maximum size because every request to the database opened and closed a connection. I changed the approach to: Creating a single connection for the entire form so that all operations use the same open connection. The connection is closed when the form closes. Even then, I now get the following type of errors: a) 8/11/2003 3:21:40 PM SqlUtility Execute Error: Transaction (Process ID 73) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.

    - two-way databinding radio buttons on a windows form? Hi, How do I get the data in the dataset to update when the radio buttons change? Do I need to add code for this, or shouldn't it happen automatically? Strangely, I have a situation where the radio buttons update the dataset when they get set, but not when they get unset - so all the fields in the ds end up with true values - which cause problems when the form refreshes the data. So I isolated the code in a mini sample and this doesn't update the datasets at all... Thanks! Heidi Tag: Chocolate IDE for .NET Tag: 54825

    - Detecting DragDrop target when dropped into Explorer I have an application which i need to allow a user to perform drag & drop of a "virtual file" into explorer. Upon dropping the file into explorer, my app would create a blank file at the location and begin downloading data into it. I can get the app to create an empty file for use with the DoDragDrop(), which essentially moves a blank file (e.g. "%TempFolder%\foo.txt") into the proper destination, but there doesn't appear to be any method of retrieving the location of the FileDrop where explorer has moved this file to.

    - ComboBox : display different string than the selected list item What I'm trying to do : - Add a form to a new project - Add a comboBox to the form with DropDownStyle = DropDown - In form load : ComboBox1.Items.Add("01 - USA") ComboBox1.Items.Add("31 - Holland") ComboBox1.Items.Add("33 - France") ComboBox1.Items.Add("41 - Switzerland") The desired behaviour is that when a user selects a list item only the number is displayed in the textbox part of the comboBox. So if "01 - USA" is selected only "01" should be displayed. Roughly translating the way this would be done in VB6 I tried the following code : Private Sub ComboBox1_SelectionChangeCommitted( _ ByVal sender As Object, ByVal e As System.EventArgs) _ Handles ComboBox1.SelectionChangeCommitted Dim listItemText As String If ComboBox1.SelectedIndex >= 0 Then 'Calculate and store the value we want to display listItemText = ComboBox1.SelectedItem.ToString If listItemText.Length >= 2 Then listItemText = listItemText.Substring(0, 2) End If 'Cancel the selection ComboBox1.SelectedIndex = -1 'Update the textbox part ComboBox1.Text = listItemText End If End Sub However this doesn't work. I've also tried experimenting with the SelectedValueChanged, SelectedIndexChanged and TextChanged events, with no better results. It seems that changing the selectedIndex in any of these routines always cancels out changes made via the text property, whatever the order the operations are carried out in. I've finally resorted to using a timer to update ComboBox1.Text after all these events have finished firing, but it's a very shoddy solution. Surely there must be a way to do this properly?

    - How to sync combo's selected item to the field's value of the current record I'm running win2k and VB.NET (.net 1.1) I have a data entry form and one of the fields is a combo who's datasource is a dataview. The dataview has 2 columns, an ID column - integer, and a name column - string. The form is not databound so the form gets populated with data for the selected reocord via values from a business class. When the use selects an item from this combo's dropdown list, it writes the ID value to the business class, and desplays the name value in the combo.text property. When I navigate to a different record, the ID value changes for this field. How can i get the combo to syncronize to this ID value, or at least set the combo's text to the correct Name? Only the ID values are persited in the business class and not the name values. In MS Access and some 3rd party combos for VB6 all you had to do was set the combo's value to the ID and it automaticly scrolled to the correct item in the dropdown.

    - How to make Win32 controls transparent? Hi, I found that checkbox, label and groupbox have painting problem with their background. I create simple frame with background picture and add checkbox, label and groupbox on it. I set transparent background on controls to see whole picture. Yes, it works. But, if I set controls style to System (to get correct XP Visual Style): checkbox and label background lost transparency!!! groupbox doesn't repaint background (group box is like window throw the frame) So, I think that these three controls in not implemented correctly in .NET. So I start to implement my own Win32 controls. I create the "static" control (label is based on it). But the problem is the same: "static" control is not transparent. So, question is: "How to make Win32 controls transparent?" I think, that it could be done successfuly, because checkbox and radiobutton is the same Win32 class, and radiobutton is painted correctly, but checkbox is not. Thanks for any advice.

I have been looking at the events and methods of the AxWebBrowser object, and I can't find it! Any help on this would be very appreciated. thanks, Ross . Tag: Chocolate IDE for .NET Tag: 54773

    - Shared properties across instances I have a console app running that references an Class Library. The console app runs fine, but I want to be able to run a windows form that will let me poll properties of the Class and reset them. As my console is running, it checks these properties, if one of the properties gets set, then my console app knows that it is supposed to do something, like shut down. I have setup a Shared property in my class: Private Shared sTest As Integer Public Shared Property Test() As Integer Get Return sTest End Get Set(ByVal Value As Integer) sTest = Value End Set End Property As I understood it, Shared properties are available to all INSTANCES of a class. Granted that the Windows form is probably a different process than the Console...is there anyway to create a truley shared property across all instances in all processes? IS there another way to do this? My console App is running through records in a DB, so I could just update the record it is working on, but that would be tedious since it would require me to poll the DB way to often. Any help would be appreciated or clues on another way to do this... Tag: Chocolate IDE for .NET Tag: 54771

    - DataGrid Updating DataSource I have a datagrid that displays a few columns from a table. I need to be able to update a process date on each row if any of the displayed columns get updated. The process date ("UPDT_DT") is not in the datagrid. I put an event handler on the textboxes in the grid so I can capture when a change occurs, but I can't seem to get the process date column updated. Here is the code I tried: CType (Me.BindingContextdgLists.DataSource, "UW_LISTS").Current, DataRowView).Row.Item("UPDT_DT") = Date.Now The line of code executes but when "UPDT_DT" is updated it resets the row in the data grid. Any ideas of how to accomplish this task ? Tag: Chocolate IDE for .NET Tag: 54769

    - How do I enable Add button in custom collection editor? Hi all. I am developing PropertyGrid runtime support for a custom class. One of my attributes in this class is an ArrayList that holds instances of another custom class. I have derived a custom collection editor for this list attribute. When this collection editor is invoked, it does display the correct caption which I assume means it knows the type of objects it is managing. My problem is the Add/Remove buttons are still disabled. From all the research I have done, I believe it is necessary for me to derive this custom collection editor because I am not working with a collection that provides access to an Item attribute for type discovery, right? I have no further enhancements that need to be made to this collection editor, so do I need to be overriding the EditValue method? If so, what should my implementation of EditValue be doing? Also, I do not have a custom TypeConverter written for the EmbeddedObject type. Is this a problem? If anyone out there can help me, I would be more than grateful. As it sits right now, I am as clueless as top management at a software design conference when it comes to collection editors. MSDN is of no help. There are a few article for the picking out there, but none explain the inner workings of the CollectionEditor in any detail. If anyone can point be to some good articles, I would love to see them. I feel like if I could better understand the CollectionEditor class, I might not be as clueless when trying to use them in real world scenarios. Thanks in advance!

Basic functionality is completed. Now i want to implement wordcompletion for different things: for example, if a user types in a tablename in order to specifiy the columns, i want to suggest the columns to him in form of a listbox popping up beneath the tablename.

I am in the procces of creating a screen designing tool for an
existing application, this tool will be used by non-technical people.
The user needs to be able to add controls to a screen and move them
around. Adding controls to a form at runtime and moving/resizing is
not a problem, but I am looking for an easy way make the controls look
like they do in the IDE, in other words they don't fire the events.
short of creating a custom control for each of the controls, that
inherits the original control, I cannot find a way to do this. Any
help or ideas would be good.

Cheers

His article and code are very readable (more so than SharpDevelop's..
