    - What is the best way to moving managed code to unmanaged code? Hi Group, I have an application which is web based. I am hosting it on VB.Net container, ie winform. Now i am facing a problem. If i make an exe of that, then i require .net framework installed on that machine where i am going to run this. So I want to move this managed code to unmanaged side i,e to VC++ by converting VB.Net code to VB 6.0 and then importing VB 6.0 dll in VC++. My Question is, Do u people have any better approach to solve this problem? My Goal is without having framework installed i want to run my app. Thanks Sachin Tag: Right to left Menu Bug!!!!

    - Owner draw on the MainMenu and MenuItem Like most fans of eye candy, I've always thought the standard MainMenu control was a bit drab. After looking at third party components, I decided to see if I could brute force it into looking nice. I set the owner draw on the menu items to true, and draw the MenuItems differently depending on whether or not their selected, thus providing nice Outlook 2003 menu styling. The only problem is, there is no 'unselected' event, so I can't redraw the item when the mouse or keyboard has moved elsewhere. The only thing I could find that semi-worked, was to call an internal method on the MenuItem object to force a redraw. This works OK for everything apart from the root level MenuItem. When I try this method on the root level MenuItem it, for want of a better phrase, spags out and messes up the painting of the whole form. Not grumbling too much, it is afterall an internal method. Anyone know of a way to work with the MainMenu et. al. classes to make them look nice rather than replacing them? Cheers, Tim H Tag: Right to left Menu Bug!!!! Tag: 75788

    - combobox not clearing I have a form with 4 combo boxes and several text boxes. All combos are filled in the form load event. The first combobox contains names and this is the code to fill it: 'istantitiate data tier object mobjUnityGroup = New UnityGroupData 'get the list of names from the data tier dvNames = mobjUnityGroup.getNames With cboName .DataSource = dvNames .DisplayMember = "Name" .ValueMember = "ChildID" .SelectedIndex = -1 End With All other combo boxes are filled at the same time and the same way (with different datasource, display member, valuemember). I select a name and in the selectedindexchanged event, the fields are filled in and bound to the form. That works fine. However, after editing the record and saving, by clicking the Save button on the form, I wish to clear all fields, including the combo boxes. All combo boxes clear except the cboName. I another procedure I am setting all combo boxes' selectedindex = 0 and then selectedindex = -1 per the bug. All works fine except for the name combo box. I am getting an error "Object reference not set to an instance of the object" Anyone have any idea why this is happening? Tag: Right to left Menu Bug!!!! Tag: 75777

    - RichTextBox Error with AppendText() I receive an error: "Object reference not set to an instance of an object." when having this code call which makes no sense as this is a richtextbox control. I have also placed the trace of this which seems to show this error occurs within RichTextBox but it doesnt fire the catch. I had to put a separate startup block in order to even catch this error - otherwise if it was in the main form it would just fail and disappear with a Windows Forms error.

    - Copy DataRows to Typed DataSet Hello, I developed a custom Windows control that displays a data grid of all orders for a customer. Since the control only needs to use the Orders table within the parent data set (along with the customer ID to filter), it seemed logical to only give the control what it needs. That's my reasoning for the code below... \\\ Public Sub New(ByRef Orders As myTypedDataSet.OrdersTable, _ ByVal CustomerID As Integer) MyBase.New() InitializeComponent() dsLocal.Orders = Orders _Customer_ID = CustomerID End Sub Private _CustomerID As Integer Private dsLocal As myTypedDataSet Private Sub ctlOrdersForCustomer_Load(ByVal _ sender As System.Object, ByVal e As System.EventArgs) _ Handles MyBase.Load myDataView.Table = dsLocal.Orders myDataView.RowFilter = "CustomerID = " & _CustomerID.ToString myDataView.Sort = "OrderDate DESC" myGrid.DataSource = myDataView End Sub /// My problem is that I can't pass the Orders table as an argument because it is part of a typed data set. VS.NET complains about dsLocal.Orders being read-only in the following statement of the constructor: dsLocal.Orders = Orders How can I set the local typed dataset table to the incoming parameter? I've also tried the Copy, ImportRow, and LoadDataRow methods with no luck. Does anyone know how this can be done? Thank you very much! Eric Tag: Right to left Menu Bug!!!! Tag: 75768

    - Finding all controls of specified type on a form I need to find all instances of a specific type of control on a Windows Form -- for example all DataGrids. The code I came up with is this: foreach(Control ctrl in this.Controls) { if(ctrl.GetType() == Type.GetType("System.Windows.Forms.DataGrid")) Console.WriteLine(((DataGrid)ctrl).Name); } This code has two problems. Something's wrong with the type checking, because it doesn't find any DataGrids on a form. Even if it did work, the second problem is that this would find only DataGrids put directly on the form (in the Form.Controls collection), but a Grid can also be in the ControlCollection of a GroupBox or some other container. How to loop through all controls in a form regardless of their parent control? Best regards, Joe Tag: Right to left Menu Bug!!!! Tag: 75766

    - saveFileDialog - bug & question Ok, I finally got to .NET development after a long break and i decided to write an app :) I started with functionality classes, so my app is currently console, and what it did (at work) was do something, get big xml document assembled, and then prompt the user for sme path to save it to and save it. Here's the basic code (sorry, it's not indented correctly, I posted right from VS and it doesn't seem to keep indent; well, it is small and simple anyway): public static int Main(string[] args) { XmlDocument xmlDocument = new XmlDocument(); FileSystemInfoLister xmlFS = new FileSystemInfoLister(); xmlFS.Extension = "mp3"; xmlDocument = xmlFS.GetFileSystemInfoList("e:\\"); SaveFileDialog saveFileDialog = new SaveFileDialog(); saveFileDialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*" ; saveFileDialog.FilterIndex = 1; saveFileDialog.RestoreDirectory = true; saveFileDialog.OverwritePrompt = false; saveFileDialog.DefaultExt = "xml"; if ( saveFileDialog.ShowDialog() == DialogResult.OK ) { xmlDocument.Save(saveFileDialog.FileName); } return 0; } The classes finsih functioning and the program hangs up. Console window is up and nothing's happening. If oyu break it, turns out, it is hanging on "if" line. I tried moving showdialog to separate line before if - it is hanging on it. If you step into, step over or continue, it continues hanging; break it and it is on the same line. No dialog appears. What's happening? Oh and btw, there's addtional problem with dialog. When it worked (at work ;) ), the dialog behaved strangely without saveFileDialog.OverwritePrompt = false; line. Namely, it returned "Cancel" result when I picked existing file and confirmed that I want to overwrite it. Why's that? Tag: Right to left Menu Bug!!!! Tag: 75765

    - Making updates to DataTable/DataGrid from within another thread Hi all! In my app I implemented a separate worker thread that handles network communication using Net.Sockets. It needs to make updates to a DataTable object, which is displayed to the user by a DataGrid control. The DataTable object is a 'public static' field instantiated within context of the main thread. The problem is that if I add a column to the DataTable from within the worker thread (eg. different thread than where the DataTable and DataGrid reside in), all columns suddenly disappear from the DataGrid view for some reason; Controller.dataTable.Columns.Add(new DataColumn("TestColumn")); If I move this code to the main thread, it works fine. After adding new column, I looked at dataTable with debugger and it seemed fine. So the culprit must be the DataGrid control. Do I need some kind of thread synchronization?

    - Databinding COM object properties When attempting to add databindings between a simple COM object properties and text box fields, I get the following error: Unhandled Exception: System.ArgumentException: Cannot bind to property or column Id on DataSource. Parameter name: dataMember at System.Windows.Forms.BindToObject.CheckBinding() at System.Windows.Forms.BindToObject.SetBindingManagerBase(BindingManagerBase lManager) at System.Windows.Forms.Binding.SetListManager(BindingManagerBase bindingManagerBase) at System.Windows.Forms.ListManagerBindingsCollection.AddCore(Binding dataBinding) ... I have a trivial form that contains 3 text boxes (id, first name, last name) and the form class instantiates the COM object in the constructor. Also in the constructor, I add the databindings: public Form1() { InitializeComponent(); m_edtId.DataBindings.Add("Text", m_user, "Id"); m_edtLastName.DataBindings.Add("Text", m_user, "LastName"); m_edtFirstName.DataBindings.Add("Text", m_user, "FirstName"); } The COM object has get/set for these three properties and works fine if I don't use databinding. Also, if I replace the COM object with a managed class that has these properties, I don't have any problems with the databinding. Thanks for any assistance. Tag: Right to left Menu Bug!!!! Tag: 75763

    - Deployment Question (networked) Hi all, I'm relatively new to .Net and especially the Windows side of it (I come from a web background). I have recently started dabbling in Windows apps - one thing I would like to be able to do is install my application across several PC's on a network, can anyone suggest how this could be achieved? My application will be using a small xml file as a config file - I was going to have one of these present for each install of the application - however I think it might be better if this was in one central location (ie on the server) so that a) a normal user would be unable to change it, b) when it needs changing its only changed in one location - not across 30+ client PC's etc. Can anyone advise as to whether this is a good approach - or whether having a config file for each installation would be better - a bonus of this would be if the server was ever to fail the client apps could still run as they'd have their own config files etc. I have used the Install Wizard in Visual Studio once - and it seemed very straight forward, and put a pretty front end to the install process - I have no idea however whether this is particularly customisable, ie, what if I want to still have a file on each install (client) that tells it where to get the main config file from - this should be perhaps something entered during the install yet the Wizard did not seem to give any options for adding extra information(ie, asking questions) during the install process - other than the location of where the application would be installed. Any information at all on this subject would be appreciated. Kind regards Rob Meade Tag: Right to left Menu Bug!!!! Tag: 75762

    - Custom Components, Threads, and Invoke I've created a custom component that is derived from the Component class. This component can be added to a form. What I've noticed is that I run into problems if I call methods on the component from a different thread than the one in which it was created. I'm aware that you should never access a windows form control from another thread but should call the parent form's Invoke or BeginInvoke methods passing them a delegate they can call that will in turn access the control. Does this apply to custom components as well? If so, is this documented any where? Tag: Right to left Menu Bug!!!! Tag: 75746

    - ExecuteCommand on Windows Service I have a windows forms app that interacts with a windows service that I made. My windows forms app can iteract with the windows service well. It can start & stop the service, etc. But one thing it cannot do is call the ExecuteCommand method of the windows service. I get an "access denied" error message when I try. I've come to understand that the service must somehow have the correct ACL's set to allow this. But I don't know how to set up the correct ACLs.

    - ApplicationContext for multiple forms and SaveFileDialog I created an ApplicationContext class to allow my application to have multiple top-level forms. The code is similar to the MSDN sample ImageBrowser article (Chris Anderson) to provide the MDI like behavior not found in Windows Forms. (I've extended it a bit so I can get any command line arguments off of subsequent invocations.) This seems to work very well for maintaining the open forms and exiting the application when the last window is closed. However, I am seeing an issue that is easy to reproduce even in a smaller sample application. 1. Start the application, see Form1 2. Create Form2 (from a button on Form1) 3. Close Form1 4. Select File.Save on Form2 which creates a default SaveFileDialog. 5. Select a file that already exists and press Save. This throws an ObjectDisposedException siting Form1 as disposed. This occurs when the SaveFileDialog is trying to display the overwrite prompt (messagebox). A stack trace shows EnumThreadWindows to disable all top level forms, retrieves the disposed form and tries to create a handle. (If I turn off the SaveFileDialog.OverwritePrompt property, it just overwrites the file but no exception is thrown). My guess is that there is a bug in the framework so I'm looking for a work around to this.

Since the amount of C++ code is very large, it's unpractical to translate them to C#. So I want to use the window in C++ as a control in C#. It seems there are a lot of method to do this : 1. Rebuild the C++ code in C++/CLI, and try to call it in managed world. 2. Pass the HWND of a C# form to the C++ code, and attach it to a C++ Window and draw on it. 3. Pass the HWND of a C++ window to C# code, and attach it to a C# form and draw on it. 4. Pass the HDC of the C# form to the C++ code, and draw on that DC. 5. ... I think this is a common problem in porting old C++ code to C#, so there must be someone has already solved this problem. Could anyone give me some advice? Thanks! Tag: Right to left Menu Bug!!!!

    - Justifying Text in a RichText control I'm attempting to format rich text with C# by sending messages to the underlying richedit control. The text can be formatted by sending an EM_SETPARAFORMAT message. However, when I set the wAlignment to be PFA_JUSTIFY, it doesn't work. I know that this option only works with Rich Edit 2.0 or later version. Wouldn't VS .Net 2003 be using at least that version of the control (or newer)? Has anyone gotten this to work? Thanks in advance! Tag: Right to left Menu Bug!!!! Tag: 75688

    - icons grouping with generic icon in XP toolbar I have my XP configured to group icons if there is more than 1 icon (window) associated with an application. each of my .NET forms has a custom icon for the application but when they are grouped on the XP icon they become a generic application icon (a white box with a blue strip on the top). if i click on this icon then a sub-menu opens up with each individual form *with* the custom icon correctly shown. how can i ensure then when XP groups icons that they retain the custom icon for my application ? -simon Tag: Right to left Menu Bug!!!!

    - Netadvantage Ultracombo & date time problem Hi I have this application that I am fighting with for days now. Here is the whole project; www.infovis.biz/tasks.zip. Please run and press the new task button to see what I mean. Much of the code is either form taskvision or infragistics samples btw and requires netadvantage 2004 vol2. I have the following problems with this and would appreciate any help I can get; 1. When I click in the clients field, I then click on any other field the cursor is stuck in the client field requiring an entry to be typed or selected. How can I make it so I can leave this field blank if I want to? 2. When a value is typed in the subject, details etc. fields, the time part of 'Remind date' disappears. 3. In any event, the remind date & time are not being stored properly in the tbltasks table in the access database. Not sure where in the code these values are lost even though I can see them on the screen when saving the new task form. 4. When I type a value in any field apart from client field, a 0 appears in the client field if it is blank. How can I avoid that? Thanks Regards Tag: Right to left Menu Bug!!!! Tag: 75665

    - Process.Start problems I'm just starting to learn VB.Net (winforms) - having known classic vb for years... I was trying to build a 'dll compiler' just for grins, using the vbc.exe that resides in the DotNet Directory. I have a form that browses to that directory, and builds a string from it, adding "vbc.exe", along with the proper arguments, like this: vbcApp = txtDotNetDir.Text & "\vbc.exe" Process.Start(vbcApp & " /out:" & sFinal & " /t:library " & txtCBDir.Text) sFinal merely builds a string with a path and the name of the new dll to save - - It always stops on this line and says : An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.dll Additional information: The system cannot find the file specified I've double checked and each of the variables in the equation have valid paths/filenames and if I used it all manually at the command prompt, it would work just fine What am I doing wrong here?

    - ContextMenuItem and shortcut Hello How do you get the control if the click event handler for ContextMenuItem was invoked by the assigned shortcut? In this case the SourceControl property may be incorrect if the context menu is shared by more than one control. The SourceControl will be the last control that displayed the context menu but the shortcut will not display the item. Thanks Tag: Right to left Menu Bug!!!! Tag: 75656

    - Owner-Drawn Buttons in C# Hello, I need a button control that will allow me to display mutiple icons/bitmaps simultaneously. Say for example you had a standard Forms.Button with text "Device 1" and you need to display small icons in each corner of the button to show state/status of Device 1. Is an owner-drawn button my only option? This sounds like a daunting task. I am unable to find any code examples or 3rd party products that even come close. Its hard to believe that I am the only one that needs such an animal. Please help if you can. Thanks, Jeff Tag: Right to left Menu Bug!!!! Tag: 75655

    - performance problerm with custom control I have a custom control A, that has two text fields and a datagrid object. the datagrid is populated within the control, quering the information from the database at the time of construction. Now I have a Form, with a tabbed control, let's name it B. On the object B we need to display N instances of object A with all the data filled. But for some reason, any time N gets larger than 10 the program slows significantly and if we need to add 30 or more instances of A the program gets a timeout exception. Any ideas?
