    - BackgroundWorker and ListView cross-thread exception Hi, I am writing an application which displays a list of computers on a network and then pings each one and displays the result. To keep the UI responsive, I am doing the ping operation using a BackgroundWorker component. The Ping method loops through a list of Computer business objects, pings the name of the computer and stores the result in a property of the Computer object called Result. The Computer object also implements INotifyPropertyChanged interface, which raises a PropertyChanged event when the Result property is modified. I have an event handler in my form class which listens for the Computer.PropertyChanged event, and attempts to update the corresponding ListViewItem with the result of the ping. However, as soon as I reference the ListView control, or any of the items, I get: Cross-thread operation not valid: Control 'ComputerListView' accessed from a thread other than the thread it was created on. How can I ensure the ListView gets updated? Regards, James Tag: get the foreground window in my application Tag: 116032

    - Toolbars change locations I am building a Windows Forms application in .NET 2.0 using VS 2005. The application has a menu strip and a tool strip control at the top of the form. The bottom of the form contains two status bars. I have found that when I build my Release version and distribute it that others using the application start it up and the toolbars and status bars change location. For example the Toolstrip appears above the menu strip control, even though in my code the design is explicitly set so that the menu is on the top and the Toolstrip is below it. I have tried setting the locations manually in the code. I have tried removing the controls from the controls collection and explicitly adding them back to the controls collection in the order that I wish them to appear. Still, regardless of what I do the toolstrips move. Is there a way to "lock" down the toolstrips so they stay where the designer (me) has put them? It looks extremely unprofessional to open an application and have the toolstrips appear above the menu. Thanks, Matt Tag: get the foreground window in my application Tag: 116007

    - Textbox input from a customized location Hi, Environment : VS 2005 / .NET 2.0 / Windows XP SP2 Requirement : class MyTextBox : TextBox { // more code } When I run the application my text box caret blinks in its usual place ( at the left ). I want the cursor to be X pixels from the left of the text box and hence the user can only enter data from that location. I tried with SelectionStart += X pixels -- it did not work Then I pinvoke SetCaretPos(X, Y ) - showed up the caret position properly. Problem : Though the caret position shows up properly, when I type text within my text box, the text is taken from the 0th location . How can I force the user to enter data from the X th location where the cursor is placed . NOTE : I have handled OnPaint to do some graphics drawing inside the textbox... dont think this has any relevance with this query ; just FYI if something is linked up to this . Thanks in advance .

    - Checkbox and selectnextcontrol When selecting a Checkbox using the SelectNextControl() method, i've noticed that the checkbox does not display the focus rectangle. By writing a simple application with a button and two checkboxes (where the checkboes have a tab index value greater than the button's), invoking the SelectNextControl() method from the button click event handler, silently moves focus to the first checkbox, but no focus rectangle is displayed. Pressing TAB once, moves the focus to the second checkbox, which can be seen as the focus rectangle IS displayed. Any suggestions on how to get the focus rectangle to display for a checkbox when using the SelectNextControl() method to move to it initially?

    - "Locked" controls? Hi everybody, in a VB.Net (VS 2005) application, there is basically three "states" in which controls are to signal what can be done with them. Usually, values loaded into controls may be looked at, but not edited ("Locked"). In certain cases (simplest: user has the permission to change data), controls allow changing their contents. While certain operations are being carried out, controls are completely disabled (i.e. the form itself has its Enabled-property set to <False>). Thus I need a way of at least visually distinguishing between <.Enabled = False> and i.e. <"Locked" = True>. The easiest way would be to have controls appear exactly as the <.ReadOnly> property does - the controls' background appears grayed out, but the forecolor remains black. This also enhances readability and copying text or seeing the tooltip is also possible. Too bad this property can only be found in some controls but not even for some the most usual ones, i.e. TextBox and DataGridView have it, but ComboBoxes and DatePickers don't. The <EnabledChanged> event didn't help either, as setting the forecolor of the resepective control seems to not be considered when the control is disabled. Any idea how I could realize something like a <ReadOnly> appearance for controls that themselves do not publish that property?

    - Getting benefits of Application Framework while using Sub Main for I have an application that uses Sub Main as the Startup Object. However, there are certain features available when enabling the Application Framework (e.g. specifying splash screen, single instance application, application-level events, etc.) that I have forfeited by doing this. I'm not sure why one can't have a Startup Object of Sub Main when enabling the Application Framework, but I'm sure there's a good reason. So, here are my questions: Right now the only thing I'm doing in the Sub Main is 1) creating some global objects that will then be available to all forms, etc. in the application, and 2) loading a login form where the user can login. I then check to see if login was successful, and run the application if it was. Here's the code: <STAThread()> Public Sub Main() CreateGlobalObjects() ' Let user attempt to login Dim login As LoginForm = New LoginForm() login.ShowDialog() If (login.DialogResult = DialogResult.OK) Then Application.Run(New MainForm()) End If End Sub QUESTION 1: Is there a way that I could accomplish the same thing but do it using a form (LoginForm I'd presume) as the Startup Object? QUESTION 2: What are the good reasons to use Sub Main rather than a form as the Startup Object? QUESTION 3: If I can't do the same thing using a form as the Startup Object, how could I 1) implement a Splash screen, and 2) limit application to single instance, bringing up existing instance if user tries to run again?

    - datagridview binding and object properties Suppose I have an object that looks like this: public class thing private mOne as string private mTwo as string private mThree as string private mFour as string public property one as string bla end property (and so on, public properties for the others) end class then I make a List(of Thing) and add a bunch of instances then I bind the list to a datagridview It's not possible for me to make the properties private My problem is that I only want to display properties One and Two in the grid view. I want Three and Four around to help out with sorting and data type conversion, but I don't want to display them in the grid. Currently, I just remove the columns programmatically. But what I really want is to decorate the properties with attributes that affect which properties appear in the grid. Does such an attribute exist? brian Tag: get the foreground window in my application Tag: 115987

    - Can't see textbox control This makes not sense at all. I created a textbox on my screen and set the name property to "Status". If I double click on the textbox, it goes to the code page and shows: private void Status_TextChanged(object sender, EventArgs e) { } So obviously, it sees the object. But in my code I have: Status.Text += String.Format("Opening {0}\n",Path.GetFileName(strFile)); And I get the following error: An object reference is required for the nonstatic field, method, or property 'FileProcess.'FileProcess.Status' How can that be???? In my FileProcess designer page I have: private System.Windows.Forms.Button button1; private System.Windows.Forms.TextBox Status; private System.Windows.Forms.Label label1; So obviously the object is there.

    - Padding problem I'm experiencing a problem with a client that I have never seen. When I receive code (windows forms) from him there is no .Margin = new System. Windows.Forms.Padding(3,2,3,2) command. I can view the form in the designer just fine, but when I compile and run the form doesn't correctly. Some of the controls (mainly buttons) will be placed off the visible area. If I edit the form, all of the locations change because my version of VS will add the Margin assignment in. If I send it back to him, the same thing happens and he can't see everything. We are both using VS 2005 with all updates applied (that I am aware of at least). Has anyone seen this before, or is there a setting that I'm just not aware of to default the padding. Any help is appreciated. Tag: get the foreground window in my application Tag: 115974

    - Application Frameworks for .NET Hello, We are about to start a big project replacing legacy application with an application that will be developed on .NET framework. Some people on our team have experience with application frameworks in Java and FoxPro, and they want to use some equivalent frameworks in .NET like Spring, CSLA.NET, Strata Frame, etc I've never used any app frameworks, so My question to you is have you every used any of these or other frameworks, what was your experience like? Can you recommand a good framework? Do application frameworks really make your life easier and cut down the development time, or do they just introduce more complexity and issues dealing with someone else's code and bugs?

    - Disable MDIChild's Restore Button I would like to disable the restore button (either make it non- clickable or hidden) in an MDIChild. However, I want the form to be maximized first (by code WindowState = FormWindowState.Maximized) before the form is shown. I also want the user to still be able to close the window by clicking the X. I have been able to achive this by the following: frm.MdiParent = MasterForm.MdiParent frm.MinimizeBox = False frm.MaximizeBox = False frm.Show() frm.WindowState = FormWindowState.Normal frm.WindowState = FormWindowState.Maximized However, this causes the form to "flash" in a normal state and then maximize. If I just set the min and max properties to false the state to maximized and show the form, the button is still available to be clicked. Its only when the code happens in the above order that I have gotten it to work. I don't mind intercepting API messages to accomplish this.

    - Multi-Threaded Form I am new to C# and am trying to build a multi-threaded web crawler. I want to crawl many sites all at once. I know how to use IHTMLDocument2 to parse the document and can build a crawler that works just fine but all the sites are being parsed by the main thread. With the WebBrowser control I can start parsing when I get the Documet_Complete event. How can I do this with each web site on a different thread? How are the Document_Complete events handled? This is an Asycronous operation and so I cannot see how it can be done. What I want is a way to have each webbrowser control (one for each web site being crawled) to operate on a separate thread.

    - Minimize + NotifyIcon Thanks in advance for any assistance. I'm developing a "panic button" application where the user single clicks on a notify icon to activate a window, then clicks on a button to send a broadcast to connected clients, then I minimize the form to hide the notification. The issue is, when the form is minimized after clicking the button to send the notice, it docks itself, albeit minimized, above the start menu. The intent here is to have no evidence on the users desktop that a call for help has been sounded. If I Hide the form instead of minimize, the form isn't visible on subsequent clicks on the NotifyIcon. Is there a way to return the form to it's original "hidden" state?

So Dr Bhavasar's treatment is good. What is amazing about Dr Bhavasar is that I know him for 6 years and he has NEVER NEVER asked me for money. His treatment is consistent and based on Rig Vedic and Atharva Vedic and Ayurvedic knowledge. If you consult him, u can understand enough to let everybody go thru recharging the body with urine therapy WITHOUT PAIN. He has told me once to do the butter-sugar-water or ghee-sugar-water treatment BEFORE the urine-drinking in the morning. When I was in pain, he told me to STOP the urine drinking (he is against it) and eat butter-sugar-water in the morning on an empty stomach (first thing) and then do ghee-sugar-water treatment 6 times a day and then butter-sugar-water treatment in the night. It worked to remove the depression/pain.

    - DataGridView Column Headers from First Row of Excel DataTable I'm sure this is something ridiculously simple or just not possible without custom coding: How do I tell a DataGridView NOT to create column headers from the first row of a data table using an Excel datasource? All I want to do is have the first row of data from the Excel worksheet be the first row of data in the DataGridView and NOT be the column headers. It would seem to be something simple to ask, but for the life of me, I cannot find out how to do it. Even in Excel itself, it has a "first row contains column headers" when importing data. Surely the DataGridView should let me turn off that kind of feature? Thanks in advance. Tag: get the foreground window in my application Tag: 115898

    - How SQL Express works with an application Let's say I build an app which includes a new sql Express database. I build the database and it's a totally independent .mdf file When it's distributed with the database file, does the end-user need to have SQL Express installed on his computer, or will the application work with the database, just like it would, if the database was MS Access?

    - Concurrency error deleting record with vs 2008 generated code Hi I have a very simple db app that was created by dragging a couple of fields onto a windows form. No additional code was added. The problem is that app gives a concurrency error while deleting a record even though no other user has access to the app. Steps to create problem 1. Create an access table Clients with only two fields; ID Auto number and Company: Text(50). 2. Make a connection to the access db in vs2008 and add the data source to the connection. 3. From data source, drag the fields ID and Company onto a windows form. This will create the binding source, binding navigator etc. 4. Click on new (+) icon on toolbar to create a new record. 5. Type XYZ in Company text field and click on Save (disk) icon on toolbar to save the record. 6. Click on Delete (x) icon to delete the record and then Save icon on toolbar to save the record deletion. At this point the error is generated with the stack trace given at the end below. What is the problem and how can I fix it? Thanks Regards System.Data.DBConcurrencyException was unhandled Message="Concurrency violation: the DeleteCommand affected 0 of the expected 1 records."

    - Selecting active query for data adapter Hi In vs 2008 dataset designer allows multiple sqls for a table's data adapter. How does one tell the data adapter which sql to use? Thanks Regards Tag: get the foreground window in my application Tag: 115874

I'm trying to get the window that is currently on top in my
application, even if I'm currently working in another application.
Something like the P/Invoke call GetForegroundWindow(), but I want it
to operate only on my application's forms. I've also tried using
Application.OpenForms[], but I don't know how to tell which one is on
top of the others.

Any ideas?

Thanks in advance,
Cosmin

Probably you want is System.Windows.Forms.Form.ActiveForm. This form is not
necessarily the form that is 'on top' - see also the TopMost form property.
It is possible for a form to be topmost but not be the active form.
