    - Verify Connetion when Form Loaded Hi, I am a beginner learning how to develop application for smart device. I want my application to verify network connection when application startup. When verifying network connection, I display status using ProgressBar. I understand that I will need to run the verify network procedure on a new thread so that the Form interface can completely load. Below is my code snippet: private Thread threadVerifyConnection; public FormMain() { InitializeComponent(); threadVerifyConnection = new Thread(new ThreadStart(this.VerifyConnection)); threadVerifyConnection.Start(); } private void VerifyConnection() { WebRequest webRequest = WebRequest.Create("UrlString"); webRequest.Timeout = 5000; IAsyncResult result = webRequest.BeginGetResponse(null, null); while (!result.IsCompleted) { if (progressBarConnection.Value == progressBarConnection.Maximum) progressBarConnection.Value = 0; else progressBarConnection.Value = progressBarConnection.Value + 1; progressBarConnection.Update(); } HttpWebResponse response = (HttpWebResponse) webRequest.EndGetResponse(result); //... do something here } But I think I must be understand something wrongly as when I run my application onto the Pocket PC 2002 Emulator, nothing come out... not even the Form!! But I can see from the emulator's memory that the application is running but not responding. Can someone enlighten me? Thank you. -- Soul Tag: Problem using SizeF / PointF etc. in PropertyGrid Tag: 71769

    - form placement: why won't this work? I have created a form that should op up as dialog; its components are initialised the way it is done in standart forms that are created in design mode, e.g. in InitialiseComponents function ( I copied the code from Form1 ;) ). But then, one bit doesn't seem to work - I placed it into the function and the form is displayed somewhere else and not in the center of the screen. Here's the code bit: this.ClientSize = new System.Drawing.Size(200, 90); //this works, just to show that I set size first and there shouldn't be any hidden errors with undefined size this.Location = new System.Drawing.Point((Screen.PrimaryScreen.Bounds.Width - this.ClientRectangle.Width)/2,(Screen.PrimaryScreen.Bounds.Height - this.ClientRectangle.Height)/2); What's wrong with it?

    - Wrapping text in DataGridTextBoxColumn I have a datagrid column which I want to expand when i type in some text. Initially I tried increasing the column width on the key down event of that DataGridTextBoxColumn, but it didn't work out as expected. Now, I am trying to increase the height of the row to make it as a multiline column. private DataGridTextBoxColumn dgcComments dgcComments = new DataGridTextBoxColumn() dgcComments.TextBox.Multiline = true dgcComments.TextBox.AcceptsReturn = true dgcComments.TextBox.WordWrap = true I am able to increase the row height, but the text is not wrapping to fit the row height. The text keeps scrolling to the left in a single line. I have set the WordWrap property to True and Multiline property to True, but it doesn't seem to work. Another thing that I tried is to display a vertical scroll bar, but that also fails to meet the reqmt. Anybody has any idea how to wrap text in a text box column of datagrid Sangeetha.

    - DataGrid with a ComboBox I have a DataGrid which has a combobox added to its controls. When the use enters a particular column in the DataGrid the combobox is shown superimposed on the usual textbox, otherwise it is hidden The user can select from the combo and when they move off it the grid shows the selected value (all this is handled in some simple code). This works fine and looks EXACTLY as if the combobox was part of the grid... EXCEPT .. when the combobox appears the user cannot tab into it, you have to use the mouse to set focus on the combobox. Anyone know a way if setting focus into the combobox ? cheers Andrew BTW The reason I don't use a sub classed DataGridComboBoxColumn is that the contents of the combobox (the dropdown list) vary depending on another column in the current grid row.

What I would like to have is that these two programs be seperate, however if application #2 is running and the user clicks on an button in application #1, that application #1 fires an event that application #2 can pick up and pass data which would be the ID number of the record in the database.

    - NotifyIcon Text (and Visible) problems I've added a NotifyIcon and it appears on the taskbar. Everything works fine, but I'm unable to change the tooltip text after I set it initially. I reset using myNotifyIcon.Text = "New Text", but it simply doesn't change. When I query the text (str = myNotifyIcon.Text), the new text is indeed there, it just isn't being updated to the tooltip. Also, I tried to force an update by setting myNotifyIcon.Visible = false, immediately following by myNotifyIcon = true, but it actually remained invisible. Very strange. Am I doing something wrong, is there a known bug, or does anyone have any previous experience like mine with a solution?.

    - not wanting to serialize an event I have a design in place for a .NET app coded in C# in which the business object drives the appearence of the UI and when the business object experiences a change, it notifies the various UIs via events . Problem is, when I tried serializing the business object to a file, when traversing the tree of referenced objects, it found the event targets, and tried to serialize my UI object (which is not serializable). I then said to myself: "simple solution: mark that event as non serializable" and went ahead to include the NonSerializable attribute, but the compiler rejected that as saying that such attribute applies only to "fields" (and I guess an event is not a field). Eventually I solved my problem by having a separate object declaring the events and broadcasting the events, an object I called EventNotifier, an instance of which is defined in my business object, which forwards the requests to broadcast a change event to the notifier object. In the code, I did mark this instance variable as [NonSerializable], thus the EventNotifier and all of its target objects (the UI classes) are never serialized. Used SOAP serializer in C# 1.1. It fixed the problem, but was wondering if others have better ideas. Tag: Problem using SizeF / PointF etc. in PropertyGrid Tag: 71727

    - Scrolling a TextBox when form isn't in foreground? I'm writing a simple debug console application that displays debug messages in a seperate application The app contains a RichTextBox control to display the text. Vertical scrolling is on. After adding text to the control, I set the text selection to be the last character of the text so that the control will scroll to always display the new text at the bottom of the control Problem is, the textbox doesn't scroll to the bottom while the console is not the foreground application. New text will be drawn when added (if it's already visible) and the scrollbar updates to show that there's more text in the control. When I bring the console forward, it THEN scrolls to the bottom of the text I've tried calling textbox.ScrollToCaret(), textbox.Refresh(), and textbox.Update(). None of these help Can anybody tell me how to get my TextBox control to scroll while in the background TIA Steve Johnso Paris Developmen Tag: Problem using SizeF / PointF etc. in PropertyGrid Tag: 71725

    - Developing a graphical interface with .NET Dear Colleagues, we developed a huge application based on Visual Studio C++ 6.0 windows forms, basically this application is one component that belongs to one distributed system, and it's functionality is to provide resources that allow the user to input data to the global system. Actually, our application is becoming unaffordable to maintain due to we've been adding to many patches to it (i know that it's not the correct way of work, but we hadn't enough time to think about redesign and develop it from zero). Well, the fact is that we are looking for new technologies that allows us to develop the graphical interface of this application, we need a technology that: - helps to maintain, extend and reuse the components of the graphical components (we will be adding new features frequently). - provide a easy API for develop with it. For us is really important that we develop as fast as possible and test the program in depth. An easy API helps. - Can be used on .NET framework, which is the framework on where we're developing all the system. Thank you !

    - Rounded Corners on Translucent Form I have a borderless form with it's Opacity set to 60% so the background shows through. It looks very nice. But I'd like to round the corners of this form. All the techniques I've seen so far for creating shaped forms involve using the TransparencyKey property of the form.

    - Given a handle, set focus to the form, how to, please? Hi! I am trying to solve the problem of Ctrl+Tab to navigate between child forms of an MDI container. The problem is when the child forms host the infamous WebBrowser control, doing Ctrl+Tab will not activate the next child form. It takes 4 Ctrl+Tab's to activate the next child. I have the toolbar and statusbar controls on all child forms and that's where Ctrl+Tab is going before switching to another form. To make the short story long, I am intercepting the keyboard events using PreFilterMessage() and raising a notify event to the parent form. I pass the child window's handle to the parent. That's where I wish to remove focus from the child form and set the focus to the next form in MDIChildren list. I am having a hard time 1) Based on the handle, remove the focus from the child form. How, please 2) Finding the next child in MDIChildren and setting focus to it. How, please Am I on the right track ?

    - Server Alive I have written an application that runs stand alone on a users machine without being on the company's network. However, there are certain pieces that requires the user to be on the network. I would like to disable these if the user is not on the network. Currently I have a method that checks if a directory path exists (a network directory) to determine if the user is on the network. This has proved inefficient as it sometimes takes a few seconds for the method to work. I need something more efficient to let me know if the user is on the company's network SystemInformation.Network just tells me if a network is present regardless if it is the company's network or some other the user has connected themselves to.

    - Invisible toolbar buttons I have added a toolbar to my WinForms app. The toolbar has 3 buttons and a separator. I have associated an imagelist with the toolbar and setup the images and buttons appropriately. At design-time I can see the bitmaps on the buttons, but when I run the application the buttons are blank. After googling around a bit I saw that some people got around this by making sure that this.toolBar.Buttons.AddRange (in InitializeComponent()) came at the very bottom of the toolbar section. I made this change but it did not affect the results. Can anyone think of anything else that might be going wrong here? Thanks, Tom Tag: Problem using SizeF / PointF etc. in PropertyGrid Tag: 71613

I have build up a nice Graphical Structure. All these have there placement
and size defined with xxxF structures because I have to use units lile
millimeters. My plan was to use the PropertyGrid wich fitted nicly to edit
the Graphics objects. But to my big suprise the attribut shows up as
readonly even though i have defined it like
[Browsable(true), ReadOnly(false),DesignOnly(false)]

Is it a bug or some limitation in the framwork? Is PRETTY critical if there
is no workaround. I suppose i could make my oen structure like MyPointF and
etc, but i would be a nightmare to cast up and down when passing this
structure to the GDI methods wich usaly takes PointF.

Any suggestions / solutions.?

I don't think there's a default typeconverter for those types. Try creating
a typeconverter for those classes that can convert to/from string
(particularly from a string) and add a typeconverter attribute for your
property that specifies to use your typeconverter. If you want it to be
expandable like a point, you'll need to override the createinstance and
getproperties related members.
