    - Dowload File Hi, I have problem with downloading a file using WebRequest and HttpWebResponse. Inorder to download this file i need to call to url that tells to prepare the file for download, and then i call to another url that downloads the file. I have a problem with that because: 1. i do not know when the server finished the preparetion. 2.i checked the HttpStatusCode but he doen't changes (myresponse.StatusCode). the problem causes the application to download only a part of the file and that because the server hasn't prepared the file yet. if i give him Thread.Sleep(100000) i do get the full file, but the file can be 100Mb and 10sec won't help. the code is: //Preparing the file todownload... //--------------------------------------------------------------------------------------------------------- HttpWebRequest webRequest3 = WebRequest.Create(d1) as HttpWebRequest; webRequest3.KeepAlive = true; webRequest3.Headers.Add("Keep-Alive", "300"); webRequest3.Headers.Add("Accept","text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"); webRequest3.Headers.Add("Accept-Language", "en-us,en;q=0.5"); webRequest3.Headers.Add("Accept-Encoding", "gzip,deflate"); webRequest3.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7"); webRequest3.CookieContainer = cookies; HttpWebResponse myResponse3 = (HttpWebResponse)webRequest3.GetResponse(); Thread.Sleep(10000); Stream ReceiveStream3 = myResponse3.GetResponseStream(); //----------------------------------------------------------------------------------- //Downloading .... //-------------------------------------------------------------------------------------- Console.WriteLine("Connecting to download link..."); HttpWebRequest webRequest2 = WebRequest.Create(re) as HttpWebRequest; webRequest2.ContentType = "application/x-www-form-urlencoded"; webRequest2.KeepAlive = true; webRequest2.CookieContainer = cookies; HttpWebResponse myResponse2 = (HttpWebResponse)webRequest2.GetResponse(); Stream ReceiveStream2 = myResponse2.GetResponseStream(); Console.WriteLine("Downloading..."); Common.SaveStreamToFile(@"C:\scrapingtest\file.csv", ReceiveStream2); Console.WriteLine("Done Downloading"); Thanks, Rony Tag: Past due query Tag: 105012

    - Maximum size of a form created using VB .NET 2005 Is there a limitation with the .NET 2005 VB form designer that prevents a designer from creating a window larger than 2972(w), 1062(h) pixels and if so, is there a way I can get around the limitation? I need to design forms having the same size as my screens 1600x1200 and 1200x1600, and am not having any luck; even setting the value at runtime rather than as a property of the designer.

    - ListControl/DataGridView/PropertyGrid Ellipses...how to? In Visual Studio, if you select Tools->Options then expand the Projects and Solutions node, and select VC++ directories, you get a grid like (or list box like) form that allows you to type in directories. If you double click on a line, you get an ellipsis that displays the directory dialog browser. Is this implemented with a data grid and two columns, and the ellipsis is hidden until there's a double click? A list box? A property Grid? There's not much documentation on ellipses, so I gather it's not part of a standard MSFT control. I haven't found many *recent* messages on the topic in these groups. I want to emulate this behavior for an app (although I'll be selecting files, not directories). The place I work for also has Infragistics controls...I may be able to get something from there, but they're tough to use. I'd rather go with something from MSFT if I could. I'll be using C#, but that doesn't make much difference, as long as it's dotnet, it should work. Thanks, Jeff Tag: Past due query Tag: 105002

    - A little help on understanding properties ?? Hi, I'm currently working on an scenegraph editor. I have a treeview, and when I select a node, it shows its properties in a propertygrid. Each node has a link to the scenegraph node, and I override the property accessors to modify the scenegraph node when the user change something in the propertygrid. For example : // this is a custom 3 dimensional vector object. [TypeConverterAttribute(ExpandableObjectConverter::typeid)] public ref struct CVector3 { CVector3(void) { x = 0.0f; y = 0.0f; z = 0.0f; } CVector3(float X, float Y, float Z) { x =X; y = Y; z = Z; } property float x; property float y; property float z; virtual String ^ ToString(void) override { return("" + x + "; " + y + "; " + z); } }; Now, in the treeviewnode, I have something like : property CVector3 ^ Position { void set(CVector3 ^ value) { // when the Position property is modified, I want // to send the new position to the scenegraph node. m_pNode->SetPosition(value->x, value->y, value->z); } CVector3 ^ get(void) { // I always get the position from the scengraph node. return(gcnew CVector3(m_pNode->GetPositionX(), m_pNode->GetPositionY(), m_pNode->GetPositionZ()); } } where m_pNode is a pointer to the associated scenegraph node. Now, the problem is that when I expand the Position property, and modify the x component, the CTreeViewNode::Position::set() method is not called. I overrided the x, y and z accessors in the CVector3, and they are correctly called, but I need to "notify" my CTreeViewNode that its Position property changed, and I really don't know how to do that :/ If anyone know how to do this, I would really appreciate a little help ^^ And I apologize for my english :/ If you didn't understand my problem, tell me, I'll try to be a little clearer ^^ Have a good day.

    - Arrow keys work in opposite direction in panel Hi, I have a panel in my project (C# .NET 2003). I have multiple radio buttons placed in it. When I press UP Arrow key, The focus in the screen moves one radio button DOWN. ofcourse if I press DOWN Arrow key the focus in the screen will move one radio button UP. I guess this is because of the way the radio button controls are arranged in the panel control collection. Could anyone suggest a way to override this behaviour in a way that when pressing UP Arrow key the focus in the screen will move one radio button UP and so on...

    - Scollable property in Listview class breaks column headers When setting the Scrollable property of a listview and resizeing it the headers will be painted wrongly. This defect is documented in MSDN as: In versions of the .NET Framework prior to version 2.0, the column headers were not painted correctly when setting this property to false and resizing the control to make it larger. To work around this issue, set this property to true in a ResizeBegin event handler and set it back to false in a ResizeEnd event handler. I honestly don't understand this workaround mentioned. The ResizeBegin and ResizeEnd event are available only on .NET framework 2.0 according to MSDN. Does this mean the provided workaround is valid only in versions of .NET framework where it is not needed? Does anyone have a .NET framework 1.1 workaround around? Tag: Past due query Tag: 104994

    - Resizing Controls that are contained in a docked Control I'm surprised that I'm only know discovering this problem, but I suppose I've never needed to change the dimension that is opposite to the docking of the control. That is, when I've docked a control to Top, I've never needed to change its height and vice-versa. But, now I would like to do this and I'm not sure what the "right way" is to perform this. Should I just add an extra container (panel, usercontrol, etc) around the control whose dimension I want to change. For example, if I have a UserControl whose width I would like to set manually and which happens to be set to Dock to Top. Should I just house it in another UserControl/Panel/Etc and then not Dock it in that container? Thanks, Novice PS If my problem is not abundantly clear - create a windows application, Add a Panel to your Form, then in the Contructor - put this: for (int i = 0;i < 50; i++) { Label label = new Label(); label.Dock = DockStyle.Top; label.Text = "MyTextMyTextMyTextMyTextMyTextMyTextMyText" + i; label.Width = 1000; label.Height = 1000; //label.Size = new Size(1000,300); panel1.Controls.Add(label); } for (int i = 0;i < panel1.Controls.Count;i++) { Console.Out.WriteLine("control width: "+panel1.Controls[i].Width+" control height: "+panel1.Controls[i].Height); } Then notice how the controls all get set to a height and width of 1000. Then try changing the panel1 to be docked - either to Fill or just one side and you'll see how the dimension changes you try to make will be suppressed. Tag: Past due query Tag: 104983

    - BackgroundWorkerProcess and GUI updates (progress windows) Hi, I'm writing a little application that scans a large number of media files for processing. The main application currently uses a backgroundworkerprocess to perform the scan. Each media file has meta data extracted and is added to one of a range of lists (pseudo-queues) for later processing. This is all fine. But, I want to provide more feedback to the end user as to progress as the process takes a considerable time. To do so I have implemented a new modal dialog which outputs counts on queues, and the current location in the filesystem that the scanning has reached. However, I have problems with this. Firstly, I tried creating the new progress window in the main form class, that then failed as when I tried to update the labels and controls on the progress window I could not as the window was created in another thread. Then, I tried to create the progress window within the method that the backgroundworkerprocess thread runs. This did not allow me to create a modal dialog as I could not pass "this" into the constructor, because the variable was not created in the same process. I don't really want to move the logic into the progress window, because I need to deal with the queues when populated. This is just all seeming to be too much of a mess. Updating a progress window is such a COMMON thing that applications do all the time. There /must/ be a tried and tested pattern for doing so, I can't beleive that .NET doesn't have a nice simple way to do this. However, I've failed to find it so far. I'm new to .NET and winforms. I've done some limited GUI programming in Delphi and a tiny bit in VB6, I'm primarily an enterprise web application developer. i.e. I can code well in the web paradigm, but my thick client gui stuff is almost completely non-extant. Any pointers to RTFM greatly accepted. (Oh, .NET 2.0 in C# Express 2005) Cheers, Mike Tag: Past due query Tag: 104968

    - Minimized Forms won't restore Hi, I have a Windows Forms App, written in c# in VS2005 Professional. The application requires the user to log on, and after a period of inactivity they are automatically logged off. The Logon is done on a seperate form, which then shows the main form. The application requires 1024 x 768 resolution (due to graphics), and so if the screen resolution is set to that it runs with no borders / title bars etc. Otherwise it runs normally in a window. I have a problem, in that if the user minimizes the main form, then when they are logged out due to inactivity, the logon form becomes shown minimized. The problem comes when the user then wants to display that form in order to log back on. If the app is running full screen (no title bar etc.) then it will not restore and remains firmly fixed to the task bar. Has anyone seen this problem before and is there a solution? Thanks.

    - Adding a UserControl to the Component Tray I have a base UserControl class - DataModule - to which I have added a SqlConnection and a DataSet. The idea is that users will build on this base class, adding their own SqlCommands as needed, but always using the same connection/dataset (i.e. a simple API). The reason for using a UserControl, is to allow users to drag-and-drop SqlCommands etc. from the Toolbox directly onto the design area; they can then select those objects from the Component Tray and edit their properties. These subclasses of DataModule will then be placed onto another UserControl containing a DataGridView, and the user will connect the DataModule's DataSet to the grid's DataSource. So far, I've got the above working great. However, when I drop a DataModule subclass onto a UserControl, the DataModule is placed on that UserControl's canvas. Because DataModule itself isn't meant to be used as a visual component, it makes more sense for it to appear in the Component Tray instead; however, I can't seem to get this to work. (I've tried the DesignTimeVisible attribute, as well as others.) >From what I've read, it seems that any component that's a subclass of Control cannot be displayed in the Component Tray. Is this correct, and if so, is there any way to work around this? Also, if you think this implementation is incorrect, please tell me! (I am using .NET 2.0 with Visual Studio 2005 Professional.) TIA.

But all works correctly only if i change the focus from the ComboBox cell to another cell.

    - Windows Forms Stylesheets? Is there anything equivalent to CSS for use in windows forms? Iâ??d like to be able to have the colors and fonts determined by some kind of configuration file (ala Cascading Style Sheets) so that individual application users can customize the user interface to there taste. Is there any simple way to accomplish this? If not, does anyone have any suggestions for methods or strategies to accomplish this? Oh... by the way, I'm using Visual Studio 2003 & VB.NET but would happily use Visual Studio 2005 if this functionality was built in. Thanks, Jonathan Tag: Past due query Tag: 104910

    - Display ToolTip on TextBox (Created on VS2003 using C#) I have derived the TextBox control to create my own control that does a lot of filtering and autocorrection of user input. I want to be able to give feedback to the user when there's a problem the input he's trying to do. A good example is in Windows XP if you go to windows explorer and in the folders view try to rename a directory with "\", this will result in a arrow tooltip to display saying that certain characters are forbidden. I was thinking of adding a ToolTop control to my TextBox control (yes I know it's wasteful, but I could work something so they all use the same tooltip, that I will work on later). Now in 2003 there's no .Show(...) method for the ToolTip control, and I don't think my company is gonig to migrate to 2005 before this week, when I have to release the software. Has anyone beem able to show the tooltip programatically without waiting for the user to do a hover? Thanks Tag: Past due query Tag: 104900

    - Detect if Workstation is locked Hi, I want to detect in my C# app (can use iterop) if the workstation is locked. I've seen on the web people saying it's impossible except by looking if the Screensaver process is running. There must be a clean way of doing it because MSN detects it and can change your status based on this. Does someone have a solution to this please? thanks ThunderMusic Tag: Past due query Tag: 104884

    - Forcing DataGridView to repaint a row/disabling a row I have a datagridview that is bound to a datasource. The under lying data is not from a database, but biz objects. The first colume (InUse) is a check box to determine if the rest of the row is enabled. When the row is not in use, it is grayed out in the CellFormatting event. After the user checks the InUse colume, the rest of the row does not get repainted. Is there a better way to control editablity of individual rows? If not, how do I go about making the whole row get updated correctly? As I click on the different cells and leave them, they change to the correct color. Tag: Past due query Tag: 104876

    - ComboBox Binding Problem I am binding a Collection Business Object to a ComboBox in Visual Basic 2005 in a Windows Form Application. The SelectedValue is then bound to another Business Object. When I create a new instance of the object I can use the Combo to look up values but display member is being cleared on losing focus. DisplayMember, Value Member, etc is set as per documentation and per other similar threads in newsgroups. Some are reset after component initialised to be doubly sure they are set. On Editing existing records combo does not display any value, even though when tested the selected value is correct. I tested code in same form with Janus Combo and it worked perfectly using properties displaymember, valuemember and SelectedValue (Using DataSourceUpdateMode.OnPropertyChanged ). This would lead me to view I am doing everything correctly but the MS Combo is not behaving correctly. Can anyone shed any light on this, is there a bug with the control?

I am trying to create a past due query of active quotes but instead of
giving me a sum, it gives me multiple sums all equal to 1. I assume it is
due to the "group by" being different but it won't let me do the query
without it. What am I doing wrong?

SELECT COUNT(QuoteDueDate) AS Expr1
FROM Quotes
GROUP BY QuoteDueDate
HAVING (QuoteDueDate < @Date)

No need to answer this. After beating the query for a while, it gave in and
now works.
