    - combobox with command items Hi I want to have a combobox with some commands in it and a data source. Basically the list should look like command1 command2 ----------- data1 data2 data3 To solve this problem i decided to derive my own combo box form standard ComboBox control. I exposed 2 properties in this class 1) List of CommandItems 2) ArrayList as data source Now i tried to merge these 2 sources as 1 source and set the data source for the base class. I also set the DrawMode to OwnerDrawVariable and subscribed to DrawItem event. I thought that i would be able to draw the items on my own. This way i am able to insert the separator between command items and the data items. However when i do this i am unable to set the DisplayMember of the combobox it doesn't work at all. Additionaly i also am thinking even if i am able to do that it has to be different for data list and the command list. Any ideas on how can i achieve this ? ~Abhishek Tag: Display html page in winform(.NET 2.0) Tag: 111617

    - Anchoring issue. Lets say I have a control at the bottom of my form and I have it set to anchor Top, Bottom, Left, Right That does exactly what I want it to do.... Ok here's my issue. I have recently taken the contents from that form and placed them on a user control instead. I set the output type to dll for the project with the user control. I implement my own interface, compile, and then place the dll in a plugins directory of my host app. My host app then rakes the directory, finds any types that implement the interface and when it finds one it loads that user control as a new tab in the host apps tab control. The interface requires that there be an init function. The host always runs this when it finds the dll and passes in DB information. Inside the init function I have tried to also set the user controls anchor like so: this.Anchor = ((System.Windows.Forms.AnchorStyles) ((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); I'm not sure if the syntax is 100% in this posting because I've commented and uncommented and recommented so many times trying different combinations. Just know that I'm setting it the same as if I were using the designer. Top, Bottom, Left, Right... Now the Host app has a tab control as I've already stated. It has it's anchor set to Top, Bottom, Left, Right so that it expands if the form does. Now when it loads, everything runs off the screen. So let me lay out the context more clearly: Host Form - Tab control - Anchor Top, Bottom, Left, Right - User Control found at runtime - Anchor Top, Bottom, Left, Right - Control - anchro Top, Bottom, Left, Right I can create the same app with just a tab control and place the end control right on a new tab page and anchor it. That works as expected and everything expands as it should. but once I put the control on a user control and then load that dynamically into the tab control setting it's anchor, everything expands way off to the right and bottom.

    - How can I use C++ codes with .NET Framework codes? I would be pleased if someone gives me a general idea; how I am going to do this. I am using visual C++ .NET 2003. I made a simple program using conventional C++ code. This program accepts data from the user, does some calculations and outputs the result back to the user using the console. Now, I want to use the .NET Framework to interact with the user through Forms, Dialog Boxes and Controls. I managed to create all the forms that I need to interact with the user and they work very well together. But, now I want to use the first program that I made from conventional C++ with .NET Framework. In other words I want the user to input data (through Forms and controls) and then I want to manipulate the data mathematically (using the conventional C++ code) and out put the result (through other Forms and controls). So my question is how can I use the conventional C++ code with the managed code and which file(s) am I going to use? For example, I have the following files:- References: .. .. Source Files: AssemblyInfo.cpp Form1.cpp Form2.cpp Form3.cpp Stdafx.cpp Header Files: Form1.h Form2.h Form3.h Resource.h Stdafx.h Resource Files: .. .. ..

    - How to tell if file is text based I want my application to load any file that is text based (php, txt, rtf, asp, etc) - - just not any binary file In the Open file dialog, that's easy, but I want users to be able to load the files by drag/drop - - so therefore, I will need to check for the types of files. I could go through the different filetypes if FILENAME.endswith(".txt"), etc, but that would end up being pretty ridiculous How can I check the file, as it comes in, as to whether it's text based or binary?

    - MaskedTextBox with negative double numbers I am trying to use a MaskedTexBox to accept positive and negative DECIMAL/DOUBLE numbers. I tried by setting the Mask to a custom mask of "0000.00" but that allows for no negatives. I tried with "+00000.00" but the same problem. According to the documentation there is a design variable ValidatingType. But at least in VC# Express 2005 such property does not appear in the list of properties at design time! So what I did was to manually set the ValidatingType to typeof(double) in the constructor. But the same problem persists. Any ideas? or was this some great half-baked idea?

    - BeginInvoke failing when executed in a form that was created in a worker thread... I previously posted this in the VB.General forum, but thought that this one might be a better place for it...sorry about the double post. I have created a simple form with code that looks like this: '****************************************************************************************** Public Class FEventRaiser Inherits System.Windows.Forms.Form Event MyEvent(ByVal eventName as string) Private Delegate Sub EventRaiserDelegate(ByVal eventName As String) Public Sub New() ...other code removed for clarity. 'Force the creation of the form's handle. While Not IsHandleCreated Dim temp As IntPtr = Handle End While End Sub Public Sub RaiseAnEvent(ByVal eventName As String) If Me.InvokeRequired Then 'Call made on thread different from the thread this form was created on...BeginInvoke. Me.BeginInvoke(New EventRaiserDelegate(AddressOf RaiseAnEvent), New Object() {eventName}) Else 'Call made on same thread as this form was created on...raise the event. RaiseEvent MyEvent(eventName) End If End Sub End Class '****************************************************************************************** If I create an instance of this form from within another form, and then make calls to 'MyRaiseEvent' from within a threaded timer, it works as I would expect: Public Class Form1 Inherits System.Windows.Forms.Form ... Private WithEvents mEventRaiser as FEventRaiser Private WithEvents mTimer as System.Timers.Timer ... mEventRaiser = New FEventRaiser mTimer = New System.Timers.Timer(1000) mTimer.Enabled = True ... Private Sub mEventRaiser_MyEvent(ByVal eventName As String) Handles mEventRaiser.MyEvent 'This event is handled on the same thread that this form's message pump is running on. Debug.WriteLine("Event processed on thread: " & AppDomain.GetCurrentThreadId) End Sub Private Sub mTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles mTimer.Elapsed mEventRaiser.RaiseAnEvent("This Works") End Sub End Class Even though the timer event handler is firing on different thread IDs than the main thread, the call to the mEventRaiser.RaiseAnEvent ends up performing the necessary BeginInvoke, which results in mEventRaiser raising an event back on the main thread...this is the behaviour I would expect (and want). If I then modify this code somewhat so that the mEventRaiser is actually created once in the timer event handler, then it all stops working (please ignore the hack method I used for instantiating the CEventRaiser object...the real way it's done is in a worker thread created at the same time the threaded timer is created). Here's the new timer event handler: Private Sub mTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles mTimer.Elapsed If mEventRaiser Is Nothing Then 'One-time creation of event raiser. It used to be created in the main thread, but now it's created in 'the context of the timer's first-time-firing thread. mEventRaiser = New FEventRaiser End If 'As before...ask event raiser to raise event. This no longer works. The BeginInvoke in the RaiseAnEvent call 'does nothing. mEventRaiser.RaiseAnEvent("This doesn't Work") End Sub End Class I hope you can makes sense of this code, and any insight you can provide would be greatly appreciated.

    - weird problem with ComboBox - DataSource contains data, but the Items collection stays empty I created a custom control which simply is a data-bound ComboBox. It has a custom property that causes an ArrayList of KeyValuePair elements to be passed to the DataSource property. It also sets the DisplayMember and ValueMember properties. What's weird, is the fact that my control sometimes works fine and sometimes it doesn't. I have no idea why, but when I put on Form1 everything is fine, while on Form2 the Items collection stays empty, although the DataSource property contains data and it is exactly the same data (pulled from the database in the same way) that I use in case of Form1. I tried to use a DataTable instead of an ArrayList, but it changed nothing. Does anybody have any suggestions? Tag: Display html page in winform(.NET 2.0) Tag: 111546

    - decimal separator, regional settings Hello there! Here is my problem, in the simplest scenario: - an Access 2000 format database (created with Access 2003) - a simple table that contains one single field defined as Number, Decimal, 18,2 - VS2005 standard, C# - a data source / dataset that cotains that simple Access table - a DataGridView, created by drag and drop, with all the helper objects (adapter, navigator etc) that edits that simple table - WinXPSP2 with ***Regional Options in Control Panel set to Romanian*** , with no other customization And here's the problem: what magic do I have to do to enter decimal numbers in that grid and save them in the database? Because as long as I type in 1,23 (given that the decimal separator in Romanian Regional Options is the comma), the grid displays it correctly, I can save it to the daabase, but when I reload the data by reopening the form, my number is 123 (and it really IS 123 in the database!).

    - No more type ahead searching for treenodes in VS 2005? In Visual Studio 2003 one of the default treeview behaviors I relied on was the ability to do type ahead searching for treenodes. Like if my treeview had nodes for the fifty states, typing "ark" would make the treeview select the Arkansas node. But, now that I've upgraded my project to VS 2005, typing "ark" makes the treeview select Alabama, then Rhode Island, then Kansas. Has anyone else noticed this?

    - Settings for Windows Service I have a requirement to create a windows service application that will need have settings (e.g. list values, connection settings, etc.) stored externally (i.e. not hard coded). To allow administrators to manage the settings I'll be creating a windows form application, very simple one, that will run in the system tray and when a setting needs to change (once in a blue moon) the administrator can right click and change/add a setting through a dialog window. The dialog will give the user the ability to restart the service so the settings can be read by the service at start up again. Here is my question. To store the settings i'm inclined to add an app.config to the windows service and have the windows form app read/save settings to the config file.

    - UserControl inheritance and the designer I've created a base class from which many usercontrols will inherit. The base class contains declarations for controls and event handlers. A derived user control contains the actual form controls (labels, textboxes, etc.). Everything seems to be working fine at run time but at at design time, the designer cannot display the derived control unless I place declarations for the various form controls in the designer code. See the code below for an example. Note that if I remove the comment from the line 'Friend Shadows Label1 As Label in the derived control, the designer is happy and works fine but of course this effectively breaks the link between the controls and their handlers in the base class. If I retain the comment, the designer gives the error "The variable 'Label1' is either undeclared or was never assigned." How do I overcome this?

    - cross-thread UI updating? hello, i am a long time asp.net developer, but new to winform programming. in the application ive been assigned, the mainform spawns a new thread to fetch a bunch of data from a method. this takes time, which is why its been placed into its own thread, allowing the rest of the ui to be usable: Private m_getDashboardDataThread As Thread ... 'this is the method that gets the data and *currently* binds it to UI m_getDashboardDataThread = New Thread(AddressOf GetDashboardData) 'not sure if this check is needed If Not m_getDashboardDataThread.ThreadState = Threading.ThreadState.Running Then m_getDashboardDataThread.IsBackground = True m_getDashboardDataThread.Start() End If problem: how & where do i properly bind this data? currently its doing the databind in the thread-method. but thats not going to work when i move the DA method to the real DAL. plus, ive heard allowing a spawned thread access to the main form UI is a Bad Thing (tm). this true, btw? anyway... what is the proper way to do this? the app needs to spawn a thread to get the data, get it back somehow and update the UI. thanks for your help, sm Tag: Display html page in winform(.NET 2.0) Tag: 111500

    - Drag and drop image? Environment: VS05, C# I'm trying to come up with a good way to create and handle drag and drop images like those that are created by the File Explorer. My first attempt was to use ImageList but this only seems to work within a single control. Drag images are limited to the control in which the drag begins. Would someone be so kind as to suggest a better way to create and show a drag image that will be created by the control in which the drag begins but will still be visible in other controls? Better yet, visible when off the application's client area, too? -- Richard Lewis Haggard www.Haggard-And-Associates.com Tag: Display html page in winform(.NET 2.0) Tag: 111498

    - Creating Files / PDFs I am not sure where to post this (I think this is appropriate). I have an application that loops through a dataview, and opens a PDF template, and populates the fields of the PDF, and saves the files on a network drive. Ih yeah, the application is a network app. Anyways, when the app runs, it will loop through the dataview (employee records) and create the files. For some users the app will only create 1 employee PDF, however for other users the app will create all 20 employee pdfs. I thought it may be issues with the creation routine, however it works some times, and not others for select users... Any ideas? I am mainly looking for debugging suggestions. I thought it may be the dataset size, however sometimes it works... And it works 100% in our staging environment... Thanks Tag: Display html page in winform(.NET 2.0) Tag: 111496

I got it.

The following code works well:
WebBrowser webBrowser1;
// do initialization

this.webBrowser1.Navigate("about:blank");
HtmlDocument doc = this.webBrowser1.Document;
doc.Write("<html>sdfsdf<br>sdfsdf<b>sdfsdf</b></html>");
