    - Double Buffer panel within SplitContainer to avoid TreeView flicke I have a treeview derived control placed within Panel2 of a SplitContainer control on a form. The TreeView flickers during updates so I set the DoubleBuffered attribute to true (in the constructor of my class derived from TreeView). It still flickers so I was thinking that it could be that DoubleBuffered also needs to be set within the parent panel that contains this TreeView derived control. However, in this case, the parent is a panel that belongs to a SplitContainer. Of course, I can't directly set the DoubleBuffered property of Panel2 and I was wondering if there is some other way to do this or if I'm on the wrong track altogether. Also, I'm using C++/CLI and the tree view nodes are user-drawn, does this for any reason automatically rule out the use of double buffering on the related tree view?

    - Need help with ContextMenuStrip in a DataGridView I want to offer the possibility for the user to right click a row in a DataGridView (Where the selection mode is set to entire row) and make a ContexMenuStrip object appear. This works well setting the ContextmenuStrip on the DataGridView (to avoid the weight of setting one for every row) but I'd like also for the underlying row to become selected. I tried to control the mouse events but that led nowhere. Anybody did this before or is it even possible ? We cna see this reaction in different software including Microsoft's mmc console so I must be missing something (and probabely a very simple something) Tag: Barcode.dll for .NET released Tag: 102941

    - Question about fetching a GIF image from assembly I use reflection to get a GIF image that contains a transparency mask (the white background should be transparent) that is part of my C# project build. The problem is that the image's transparency property disappears when I render it making it look as if were a JPEG image. The code I use is: Assembly assem = this.GetType().Assembly; Stream streamTransPic = assem.GetManifestResourceStream("MyProject.images.transPic.gif"); transPic = System.Drawing.Image.FromStream(streamTransPic); It is rendered with Graphics.DrawImage method in gObj.DrawImage (transPic, rect); where gObj is an instance of Graphics and rect has already been defined. If I read the image from a file rather than storing it in the compiled assembly, its GIF transparency property is present when I render it. But I don't want to use separate data files with production code. Tag: Barcode.dll for .NET released Tag: 102936

    - access the calling user's config info from a dll? Hi, I am using C#. My WinForm project has a config file created by VS2005 containing some user scoped properties. It has setup as the config file as follows: <userSettings> <MyNameSpace.Properties.Settings> <setting name="MyProperty" serializeAs="String"> <value>"aaa"</value> </setting> </MyNameSpace.Properties.Settings> </userSettings> I can easily access the property value in a type-safe manner in my WinForm via: Properties.Settings settings = MyNameSpace.Properties.Settings.Default; MessageBox.Show(settings.MyProperty); My WinForm uses some BO's from a dll. How can I access the config properties from within the dll? The class which contains the property specification is marked internal to the WinForm exe. I have read the helptext regarding ApplicationSettingBase and ConfigurationManager classes. These are both new with .Net 2.0, so they most be both current technologies. Neither sections of helptext refer to the other. I can't understand what job each of them are trying to do, or how they relate to each other. If one wants to access the calling user's config info from a dll, which facility should I be using? thanks Barry Mossman Tag: Barcode.dll for .NET released Tag: 102931

I get a log in screen that won't accept any login. Logged in as the same user from another pc, it works fine. It seems on the pc that worked a warning run app screen came up that didn't come up on the one that failed.

    - Moving childs within a MDI parent area Hi, I am developing an application using VB.net (2005) and I would like to know if there is a way for allowing MDI childs just to move within the borders of the MDI parent. Now the MDI childs are able to dissapear for a part out of the screen, and then scrollbars appear. I would like to prevent that. I've tested a little with the Move event, by changing back the MDI childs position at a certain position, but this results in a nasty flickering effect. Is there anyone who knows how to handle this problem ? Thx, FrÃ©. Tag: Barcode.dll for .NET released Tag: 102929

    - Using Microsoft Chart Control in dotnet I am trying to use the Microsoft Chart Control COM component in dotnet 2.0 but keep getting "class not registered" exceptions when I try to run the code. I have done the following so far to try and get around this issue: - registered mschart20.ocx using "regsvr32 mschrt20.ocx" - registered AxInterop.MSChart20Lib.dll using regasm - registered Interop.MSChart20Lib.dll using regasm - reinstalled Office Web Components 2003 Unfortunately, none of these has made any difference. More or less, I am doing the following with my code: - create new project - add Microsoft Chart Control 6 reference (listed in COM object list) - drag a Microsoft Chart Control 6.0 (SP4)(OLEDB) to my form - Try to run the code - class not registered exception is thrown every time Does anyone have any ideas?

    - .Net: File copy control Hi, I'm looking for a Windows Forms Control to copy files and direcotries between two directories. |-----| |-----| | | <- | | | | | | | | -> | | |-----| |-----| What I've found up to now: System.Windows.Forms.OpenFileDialog System.Windows.Forms.SaveFileDialog System.Windows.Forms.ForlderBrowserDialog As the names state these are dialogs and not simple controls, and thus cannot be arranged like the schema shown above. Microsoft.VisualBasic.Compatibility.VB6.DirListBox Microsoft.VisualBasic.Compatibility.VB6.DriveListBox Microsoft.VisualBasic.Compatibility.VB6.FileListBox Is it a good idea to use VisualBasic controls in a C# application? These controls don't look really nice and they don't really satisfy the schema shown above (z.B. FileListBox only shows files, no directories.). http://www.windowsforms.net/ControlGallery/default.aspx?Category=6&tabindex=5 http://www.codeproject.com/ These sites have some interessting controls. Can someone recomment one of these controls? Or dissuade from one? The controls should be usable in a professional commercial application (license, stability, internationalization, use system icons,...). Other recommendations?

    - Why does a WinForm stay in memory if the local reference var goes out of scope? Why does a WinForm stay in memory if the local reference var goes out of scope? Hello all, After programming in C# and VB.NET for 4 years, it finally dawned upon me that something Very Fishy is going on when you create a second form. Why does it stay in memory when the form-variable goes out of scope? In FormMain I have a cmdOpenFormTest with this event handler: cmdOpenFormTest_Click(object sender, EventArgs e) { FormTest frm = new FormTest(); frm.Show(); //for this test we do NOT do frm.Close() or frm.Dispose() //you may leave next line out, doesn't make a difference frm = null; } FormTest is a form with nothing on it, not even a button. I could even have done, with the same effect: Form frm = new Form(); A second button on FormMain allows me to do GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); Now the questions: * why does FormTest stay visible when its variable has gone out of scope a long time ago? Even after GC.Collect()? * Why doesn't the garbage collector kick in? * Why doesn't base.Finalize() run, that is, the base-base-base class's destructor? * Why don't we see .Dispose(false) running? ---------- There is a lot of interesting talk in the newsgroups about what's going on after frm.Close() and frm.Dispose(). frm.Close does a this.SendMessage(WM_CLOSE), just like in a Charles Petzold C Windows program. This comes back to the form in the WMClose() handler. Here, if I'm not mistaken (can look it up in Reflector), after some work .Dispose() is called, leading to Dispose(true), leading to the cleanup of all the unmanaged resources, underlying windows & window handles, and the like. There is also interesting talk about mem leakes related to a static hashtable with MenuItem's and references that don't go away. But in my case I do NOT call Close() or Dispose(). Who is keeping a root reference to FormTest? In the old days, using Access 95 and 97, the behaviour was as expected: if you created a second form with a local form-variable, the newly created form would immediately disappear after the local var went out of scope. I tried to figure things out with the CLR Memory Profiler from the msdn website, but I saw a lot of colourful lines and no clear call stack. Any ideas?!?!?!?!?

    - SHDocVw in Separate Process I am using the SHDocVw.InternetExplorerClass in a windows console application. I assign this as my Webbrowser1 and call methods and properties from this (like Webbrowser1.Visible) and it works fine for what we need so far. However, when we start another instance of the application on the same machine, the 2nd Internet Explorer instance runs in the same process in task manager although the application grabs it's own PID with each instance. We are using Windows XP Pro (SP2). Is there a way to use the SHDocVw.InternetExplorerClass and run IE in it's own separate process with each instance of the application? Help appreciated.

    - ProcessCmdKey up to parent form Hello, I have an MDI application which manages smaller tool windows (implemented as separate, modeless Forms), sort of like Adobe Photoshop. The menu items in the main app form can be activated using shortcuts. When I do something in one of the tool windows, keyboard focus changes to the tool window. Is there a way I can have the shortcuts for the menu items in the main app work when keyboard focus is in the tool window? I was hoping there would be a solution like overriding ProcessCmdKey, and calling the tool window's ParentForm.ProcessCmdKey(), but obviously I can't. Is there another way to have shortcuts processed by a different form than the one which has keyboard focus? Thanks, Jon Tag: Barcode.dll for .NET released Tag: 102889

    - Limit to range of colors displayed by Label control? Hi, I was just curious to know if there was a limit to the range of colors a label control can display. For instance if I set a label control's ForeColor to 28, 23, 15 it renders black (on my system, at least - but I'm running an nVIDIA GeForce 440 MX 64MB card running in 32-bit color, which should be plenty able to render that properly). Anyway, it occurred to me that perhaps the label had a restricted color range, and if this is the case, which other controls might this restriction apply to? thanks! evan k. stone | software engineer ---------------------------------------- santa rosa, ca, usa Tag: Barcode.dll for .NET released Tag: 102886

    - Question about DataRows/DataGrids Hey all, I have a question about using DataRows (and ultimately, its interplay with a DataGrid) So I create my DataSet, create a DataTable, configure it with columns and then add rows like so: (C++ .NET) DataTable* table; //assume setup DataRow* row = table->NewRow(); //columns 0,1, and 2 are all setup in the table row->set_Item(0,fi[i]->get_Name()); //assume fi[i]->GetName() returns some string* row->set_Item(1,S"Queued"); row->set_Item(2, S"---"); table->get_Rows()->Add(row); After I have added the row to the table, can I still use the DataRow object to change data in the row, or is this a no-no ? Do I need to wrap the changes with calls to DataRow::BeginEdit and DataRow::EndEdit? After I have added the DataTable to the DataSet and, set a DataGrid to refer to the DataSet and display the DataTable I setup, can I still change stuff then? If I do, what is the proper way to update things? Should I call DataGrid::Update()? I'm dealing with some nasty problems where I get the "No original data" error from my datagrid while I'm updating literally all the rows in the table by just directly referring to the DataRow object I got from DataTable::NewRow() in the beginning. tia, rj ryan Tag: Barcode.dll for .NET released Tag: 102885

    - Windows Service and Threading What is the proper way to terminate a Thread in a Windows Service? I have a windows service which starts up three threads which run in a while loop as long as a boolean flag is set to true. These threads each sleep for X ammount of time then start processing again. Since this is a service it's basically running in an infinite loop. When the user goes to stop the service, I have been calling the Thread.Abort() method, which throws a ThreadAbortedException. I've also tried using the Thread.Interupt() method to wake any sleeping threads, but that too throws a ThreadInteruptedException. What is the proper way to kill these threads in the 30 second timeframe that the windows service framework gives a service to respond back? If catching these Exceptions are the correct way to stop the service, what is the correct way to know if the service actually dies on it's own for some reaon (i.e. god forbid locking)?

    - Interacting with modal and modeless forms Hi all I am writing a piece of control software that monitors data from a data source and controls the data source peripherals. I am using a Modeless Form to monitor the data and to change the data source parameters in real time. I am using Modal Forms to control the peripherals, because these are popped up, used and closed again when required. My problem, is that whenever I open one of the Modal Forms, the Modeless Form no longer responds to input. I could do this in C++ / MFC by giving the Modeless Form a NULL owner, but it seems as though in DotNet a NULL owner impies the Main Application Form.

    - Change the value of a Listview subitem I have a ListView box in my form which is populated by an array : Dim item2 As New ListViewItem(index & ".") item2.Checked = True item2.SubItems.Add(r.description) item2.SubItems.Add(r.host) How can I change the value of these subitems afterwards? For example: I have 2 forms. One with the ListView box and one with some textfields to enter some data (description, host, ...). After a user has entered the data everything is stored in an array (r.xxxx) and two fields (description and host) are shown in the ListView box as a reference. Now the user selects this entry again and clicks the button "Edit". The second form opens again showing all previously entered data and the user does some changes, eg. modifying the "host" entry. After clicking OK the value for "host" in the ListView box should be updated. Everything works already (all forms, add, edit, remove, storing data (also edited data) in an array, etc.). Only the update of the ListView is missing. Tag: Barcode.dll for .NET released Tag: 102864

    - TreeView text truncated Using .net 2.0 and C# I have a TreeView in which I put some nodes with rather long text.

    - ClickOnce and login on as a different user Hello group I'm developing an C# Windows Forms application that I would like to deploy using ClickOnce. One of the computers that the application is deployed on, is a computer that is always loged on as a generic "controlroom" user. This is necessary for some of the other applications running on the computer. On my application, the user should always logon as himself or herself. Therefore I need to present a login form to the user as the first thing. I have been considering using RunAs, but I'm not sure that is possible along with ClickOnce, at least nok using the GUI of RunAs. I have looked at the Windows API LogonUser, but that seems to be requiring unsafe code permissions and FullTrust, and I was hoping that I could avoid giving those permissions to the application, especially when I'm deploying it using ClickOnce. Do you have any alternative suggestions? Thank you for your answer. Regards Anders Olsen Tag: Barcode.dll for .NET released Tag: 102854

    - Can't print in landscape orientation Hi group. I'm having problems getting this C# code to print in landscape orientation: private void MyPrintDocument_BeginPrint(object sender, System.Drawing.Printing.PrintEventArgs e) { MyPrintDocument.PrinterSettings.DefaultPageSettings.Landscape = true; MyPrintDocument.PrinterSettings.DefaultPageSettings.Margins.Left = 25; MyPrintDocument.PrinterSettings.DefaultPageSettings.Margins.Right = 25; MyPrintDocument.PrinterSettings.DefaultPageSettings.Margins.Top = 50; MyPrintDocument.PrinterSettings.DefaultPageSettings.Margins.Bottom = 50; } private void MyPrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) { if (k < MyReportReader.Pages.Count) { if (chklstBills.GetItemCheckState(k) == CheckState.Checked) { e.HasMorePages = true; Font prFont = new Font("Courier New", 10, GraphicsUnit.Point); Page currentPage = (Page)MyReportReader.Pages[k]; int j; for (j = 0; j < currentPage.Lines.Count; j++) { float x, y; x = 26; y = 50 + (float)j * (float)12.5; e.Graphics.DrawString(currentPage.Lines[j].ToString(), prFont, Brushes.Black, x, y); } } k++; } else { e.HasMorePages = false; } } ReportReader and Page are custom classes for this application MyPrintDocument is an instance of the PrintDocument class. Using .NET framework 2.0 This code prints in portrait orientation in any printer no matter what I do, ignoring the 'MyPrintDocument.PrinterSettings.DefaultPageSettings.Landscape = true' statement in the BeginPrint event handler. It's not a printer problem. Any help will be greatly appreciated. Tag: Barcode.dll for .NET released Tag: 102853

    - How to find the parent form for a ContextMenuStrip Hi, I have a ContextMenuStrip that is used on various forms. When somebody opens the context menu on a specific form (e.g. Form2) and clicks a menu item, I need to execute some action on that form. Is there a way to determine the form from which the context menu was invoked in the click event handler? Usually I do this with Control.FindForm() but that does not work for the ContextMenu.

    - override maximize event I'm looking to execute a function when the Max button is clicked. I'd like to override the maximize event on an MDI child form so that instead of maximizing, it just fills the MDI area. I've found the code to max the form to the mdi size, but no luck on how to execute my function on the Max button click. I've been looking for a solution, but still no luck. I found the "MinMaxFormSize" article but it's not quite what i'm looking for. Thanks for any help. rich - vb.net '03 Tag: Barcode.dll for .NET released Tag: 102841
