    - MDI Child Form size Hi All, Is there a way to make a MDI Child's height larger then the parent form? For example, when I try to add a new type of MDI Child to a Parent form that is setup for a width/height of 800 X 600, and I want to have a longer Child form (say the size will be 800X1200). Everytime I try this, Visual Stuido resets the height of the child to be near what the height of the Parent is. Thanks, T.

    - Property Grid Stops Expanding Expandable Properties I am using the PropertyGrid control. I have altered the BrowsableAttributes property to a custom attribute. When I do this, expandable properties will no longer expand in the PropertyGrid. For example, I have a public font poperty. I can call up the font dialog from the PropertyGrid, but I can't expand the property to see the font members. If I don't change the BrowsableAttributes the PropertyGrid behaves normally. Any ideas? -- Howard Swope Software Engineer Spitz, Inc [http://www.spitzinc.com] Tag: Camera Sale -Nikon , Canon, Minolta , Sony ,Xcam2 , Fujifilm , Tag: 52174

    - Vanishing Custom User Control Bug Hi I am currently designing a Windows form which inherits from a basic custom dialog form. The new form uses custom user controls. When the form is compiled, the custom controls disappear and the message "There is already a component named 'myControl'. Components must have unique names, and names must be case-insensitive. A name also cannot conflict with the name of any component in an inherited class" appears for each disappeared control in the task window. This is very confusing because the form that is inherited does not contain any instances of myControl, only two windows buttons and an error provider. Has anyone a clue as to why this may be happening? Regards, Phil Tag: Camera Sale -Nikon , Canon, Minolta , Sony ,Xcam2 , Fujifilm , Tag: 52169

    - Repost: Problem Retrieving DataSet Returned By A WebService Hi, I'm working on a project which includes WebServices and Windows Form application. The Windows Form application will call the WebServices to retrieve data from database. The data will be returned as DataSet. Now, here's the problem. On .NET Framework 1.1, if any rows in the dataset returned contain errors (marked by calling the SetColumnError() method or setting the RowError property of the DataRow), I get the following error message in the Windows Form application, "There is an error in XML doument (1,xxxxxxx)" If I forced the Windows Form application to run on .NET Framework 1.0, everything works fine. Is this a bug? Or I need to make some code adjustment because of changes to the Framework? Here's the partial code for the WebService project Code: <WebMethod()> _ Public Function RetrieveDataSet() As DataSet Dim ds As New DataSet Dim dt As New DataTable Dim row As DataRow Dim i As Integer dt.TableName = "TestTable" dt.Columns.Add("TestColumn1", GetType(String)) dt.Columns.Add("TestColumn2", GetType(Integer)) ds.DataSetName = "TestDataSet" ds.Tables.Add(dt) For i = 0 To 10 row = dt.NewRow row("TestColumn1") = "This is row " & i row("TestColumn2") = i dt.Rows.Add(row) ' The following code trigger the error after the DataSet ' is returned to the calling Window Form application row.SetColumnError("TestColumn1", "Error message here") Next Return ds End Function For the Windows Form application, you need to insert a datagrid control (assumed as datagrid1). It will look something like this, Code: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim ws As localhost.Service1 Dim ds As DataSet Try ws = New localhost.Service1 ds = ws.RetrieveDataSet Me.DataGrid1.SetDataBinding(ds.Tables(0), "") Catch ex As Exception MsgBox(ex.Message) Finally If (Not (ws Is Nothing)) Then ws.Dispose() End If End Try End Sub I really hope someone could help me out with this one.

    - Continued problem with Socket in User Control in IE Hey guys (and ladies), To get started, all of this is going to be run under Full Trust permissions, so I know that it isn't a security problem. I have a UserControl that contains a socket that connects to our server practically instantly when the UserControl is hosted in an executable residing locally on a client machine. If I attempt to host this control in Internet Explorer, the connection event takes almost exactly a minute to be fired, after which everything is happy and connected. Now this only occurs when one initially browses the page, as subsequent refreshes (F5s or the little button) connect immediately. To verify that this is a client side problem, I put 10-second-interval heartbeats in the socket stream from the server. Sure enough, on an initial browse and subsequent 60 second wait, the client side socket buffer contains the six heartbeats. Upon refreshing, the buffer contains only a single initial heartbeat. I've run the command line tool "netstat" to check the established sockets and see only a single socket connected and have also verified open and close events on the server. The funkiest part: both netstat on the client and the server (via an attached process) show immediate established connections, but it seems like something has delayed the first connection event to Internet Explorer. Finally, any web service calls that are made during this socket connection window are also hung up. If these calls are made during times when the socket is not attempting a connection, the calls go through in expected amounts of time. This is the case even if the call is made when the page is initially loaded for the first time. If anyone has the slightest hint, it would be highly appreciated.

    - Strange Issue with MDI childs and Merged menus. Have a MDI parent with a menu and a MDI child with a menu that gets added to the parent - nothing fancy. One the parent, there is a menu (file/new) item that loads and shows a new child. Works fine so far. However, if you click (file/new) 2 or 3rd times, without actually clicking on the new child first, I will get: "An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll Additional information: Object reference not set to an instance of an object." However, if I click inside the ListView in the first child (I think because it changes the focus off the menu) then I can continue creating children without this error. You must *actually click the control as setting the focus in the code does not stop the problem. This does not happen if I remove the menu from the child or if I do not start the child as MDI. Therefore, I am guessing it is an issue with merged menus and/or mdi children. Anyone run into this before? Is there a way to simulate the mouse click in code (i.e. not just setting the focus). --wjs Tag: Camera Sale -Nikon , Canon, Minolta , Sony ,Xcam2 , Fujifilm , Tag: 52115

    - Windows Forms Inheritance, Incomplete? I was playing around with Windows Forms and found out this Forms Inheritance feature. The moment I saw that, I felt this can be used effectively if the application contains couople of forms which have a consistant look and also shares SOME similar functionality between the forms. Lets say for example, I have 2 forms and both forms have buttons as (New, Edit, Save, Close) Both the forms before showing, should do a security check(say in forms load event) In the old vb scenerio, we would create 2 similar forms seperately and do code cut and paste for each form which have the similar functions. But here, with forms inheritance this should be automaticaly done. But what happense when u inherit a form at the moment is, it only sets the controls MODIFIER poperty to say Protected, Proteted Internal etc.. But If I want to override the parent forms functionality , say overriding CLOSE buttons click method, I have to manually edit the parents click event as; protected virtual void btnClose_Click(object sender, System.EventArgs e) and then edit the close button event in the child form to; protected override void btnClose_Click(object sender, System.EventArgs e) And then, in the child forms' event registration for CLOSE button should be removed/commented(the line below). //this.btnClose.Click += new System.EventHandler(this.btnNew_Click); Otherwise, when the child instance get created it will register 2 events(cause it goes up the inheritance hierachy and creates parent form instance first and then come back to child form) so if u click CLOSE button once, it will call the close method twise!!!!! My question is why they didn't automate this couple of steps ? If a forms controls have been set to Protected / Protected Internal, they could have generate the code so that it will really work. I want to know what you guys think. May be I have taken the whole thing from the wrong end. May be forms inheritance is there ONLY to get the UI duplicated? is it?

    - Bug in datatable.select If you use a datatable select on a column that contains a GUID you will have a major problem if you are not using US language. We are using Danish language and when selecting like this: ds.Tables(0).Select(GuidColumn = 'SomeGUID') It will not always return the row as expected, I suspect the problem is that in Denmark the character "å" is the same as "aa" and one side of the equation returns "å" while the other returns "aa". This is a serious bug and should be fixed ASAP - I have reported this to MS 6 months ago, but to no avail. For anyone interested I can send a project that demonstrates this behaviour.

    - Quote extraction from Yahoo Historical Quotes I have the following method that retrieves quotes from the Yahoo historical quotes web page. According to their FAQ, there is no limitation on the number of quotes one may download, and because the problem seems to come and go, I'm concerned it may be a problem with my code. In particular, the problem seems to occur when I retrieve quotes over a long period of time. Normally the routine runs every night and downloads the previous days quotes. Occasionally, however, I'll download one or more years worth of quotes for several stocks. It's on these occasions when the code seems to fail. It doesn't fail the first time, though, and it won't necessarily fail on the stock that I'm retrieving multiple quotes from. The exception that is thrown is: "System.Net.WebException: The underlying connection was closed: The server committed an HTTP protocol violation." The exception is thrown at wrq.GetResponse(). I originally thought it was because I was going through a machine using Internet Connection Sharing, but then I did it directly to the internet without a proxy, and the same problem occurred. Anyone have any ideas? Code follows: public QuoteList GetQuoteHistory(Stock StockOb, DateTime StartDate, DateTime EndDate) { if (StartDate.Year < 1970) { StartDate = new DateTime(1997, 1, 1); } bool done = false; int tryCount = 0; QuoteList list = new QuoteList(); while (!done) { // Build url query string string url = @"http://" + yahooIP + @"/table.csv?a=" + ((int)(StartDate.Month - 1)).ToString() + @"&b=" + StartDate.Day.ToString() + @"&c=" + StartDate.Year.ToString() + @"&d=" + ((int)(EndDate.Month - 1)).ToString() + @"&e=" + EndDate.Day.ToString() + @"&f=" + EndDate.Year.ToString() + @"&s=" + StockOb.Ticker + @"&y=0&g=d&ignore=.csv"; WebRequest wrq = null; Stream strm = null; StreamReader sr = null; try { wrq = WebRequest.Create(url); wrq.Timeout = 30000; wrq.Proxy = WebProxy.GetDefaultProxy(); strm = wrq.GetResponse().GetResponseStream(); sr = new StreamReader(strm); } catch(System.Exception ex) { if (null != sr) { sr.Close(); } if (null != strm) { strm.Close(); } // Check to see if the operation timed out. If it did, // retry a couple of times. if ("The operation has timed-out." == ex.Message) { tryCount++; if (tryCount > 2) { return null; } continue; } else { return null; } } string line; try { // If there's no day, close out. if (null == (line = sr.ReadLine())) { return null; } while (null != (line = sr.ReadLine())) { // Parse quote data nad add the quote if it's not already in the // list of quotes char[] splitCh = new Char[1]; splitCh[0] = ','; string[] items = line.Split(splitCh); Quote quote = new Quote(); quote.QuoteDate = Convert.ToDateTime(items[0]); quote.OpenPrice = (float)Convert.ToDouble(items[1]); quote.HighPrice = (float)Convert.ToDouble(items[2]); quote.LowPrice = (float)Convert.ToDouble(items[3]); quote.ClosePrice = (float)Convert.ToDouble(items[4]); quote.Volume = Convert.ToInt32(items[5]); if (false == list.ContainsKey(quote.QuoteDate)) { list.Add(quote.QuoteDate, quote); } } } catch(System.Exception ex) { Trace.WriteLine("Unknown exception processing request: " + ex.ToString()); } finally { // Close everything nice and clean sr.Close(); strm.Close(); done = true; } } return list; } Tag: Camera Sale -Nikon , Canon, Minolta , Sony ,Xcam2 , Fujifilm , Tag: 52090

This class is bound to a data grid. whenever my MyDataList is updated [example: OnListChanged(new ListChangedEventArgs(ListChangedType.Reset,-1));] (another thread invokes updates on the UI thread) the form containing the DataGrid takes focus and then acts like something set TopMost = true on the containing form! I can't figure out what is causing this, and it's driving me insane!! Has anyone encountered this before, and found a fix? Or does anyone have a suggestion?

    - Visual Inheritance for ComboBox Hi All, Just been toying around with inheriting from the ComboBox control.

Also - no problem dragging and dropping the custom combo onto the design canvas. Strange thing is, after switching between design time and code a couple of times and running it - the font seems to change into a bigger font, something like Arial bold or such. Also, I suppose I need to specify some attribute tags before the class definition. Any ideas or suggestions?

    - MDIChild forms maximizebox. Hello ALL, I have this situation: 1. A MDI Form named frmPrincipal; 2. A MDIChild form named frmCustomers; When I show the frmCustomers form, from a click event of a button of frmPrincipal, like this: frmCustomers.MdiParent = this; frmCustomers.WindowState = FormWindowState.Maximized; frmCustomers.Show() The frmCustomers form shows ok, but the minimizebox, maximizebox and controlbox appears, and I can´t like this. In the frmCustomers properties I set false to maximizebox, controlbox and minimizebox, but they appears yet. I try to remove the border of the form (set FormBorderStyle = None) but don´t work too. Please, how can I hide this buttons? Thanks in advance and sorry my English. Fernando Lopes Marília - São Paulo - Brazil.

    - Problem with drawing over the top of a background form Hi, I am hoping someone can point me in the right direction. I am working on a program that has a form that has a background mage that the user can change. Currently I assign in directly to background image. After an image is assigned to the background the user has the ability to draw rectangles on the image using the mouse to define the regions. To do that I create a bitmap and constantly redraw the rectangles on it that are stored in a linked list each time the form repaints.. the problem is that because of this bitmap, I never see the image assigned to the background. Of course this makes sense since I am creating a bitmap. I've tried setting the bitmap to be transparent, and that allows me see the background image, but everytime I use the mouse to draw or resize a region, it doesn't refresh properly and I'm left with tons of rectangles on the screen, instead of just the final rectangles position. Is there any easier way to do this? I've also tried to assigned the .BMP image I use directly as the bitmap I am creating the rectangles on rather then the background, but then I get another error saying "Additional information: A Graphics object cannot be created from an image that has an indexed pixel format." The bmp is an 8 Bit format image. I've also tried converting it to a GIf with no success. I was going to post some of the code, but figured the post was long enough, if anyone is interetsed in seeing what i have so far, just let me know. I appreciate any help you guys can give me.

    - Am I doing something wrong? (Variables) Hiya all, I am developing a windows form application. I am coding in C#. What I have is two forms/Classes, frmMain & frmAdd and they both have the same default namespace "Q.A._Testing_Centre". In frmMain I have initialize & instantiated my variable as "public string userName", where the user input name is stored. I am trying to get the stored data propertied from my frmMain to my frmAdd. I thought this is the correct syntex for outputting the info in my textbox (scratching my head), maybe it's not. So please let me know if you can help, or where I'm going wrong. Code is as follows: namespace Q.A._Testing_Centre { public class frmMain : System.Windows.Forms.Form { public string userName; <<<---- I want the data from here ... ... ... namespace Q.A._Testing_Centre { public class frmAdd : System.Windows.Forms.Form { private void SubMainMenu() { frmMain Main = new frmMain(); txtBoxSample.Text = Convert.ToString(Main.userName);<<<--- to output in my textbox here ... ... ... I have tried a sample textbox with in frmMain and this data is in fact stored until I exit my program. But I cannot seem to reproduce the same textbox output in frmAdd. I seem to get a blank textbox area. Alternatively I have try "txtBoxSample.Text = Main.userName" syntex which does not work as well. Or maybe if someone has a better alternative, please feel free to let me know. All help is truly appreciated & thank you all in advance.

    - DateTimePicker BackColor Property Hi, for those of you, who need a backcolored DateTimePicker control: this ist my implementation of the BackColor property for the standard DateTimePicker Control (which does not work): public class MyDateTimePicker : DateTimePicker { #region internal set backcolor hack private Color _BackColor = SystemColors.Window; public override Color BackColor { get { return _BackColor; } set { _BackColor = value; Invalidate(); } } protected override void WndProc(ref Message m) { if (m.Msg == (int) 0x0014 /* WM_ERASEBKGND */) { Graphics g = Graphics.FromHdc(m.WParam); g.FillRectangle(new SolidBrush(_BackColor), ClientRectangle); g.Dispose(); return; } base.WndProc(ref m); } #endregion } ... seems to work quite well. claudio Tag: Camera Sale -Nikon , Canon, Minolta , Sony ,Xcam2 , Fujifilm , Tag: 51969
