    - OnSetComplete, OnSet methods do not fire I have a datagrid bound to a strongly typed collection implementing iBindingList. When an item is added to the datagrid, OnInsertComplete fires just fine as I would expect it to. However, the OnSet and OnSetComplete methods don't seem to be firing at all. What I really want to do is: When a row is added to the list (NOT the first row), default one of the columns from the row above it. So when row2 gets added, it should automatically have the value from row1's column X. Any thoughts/suggestions? Tag: Smarthclient and crystal rpt viewer Tag: 86035

    - Capturing web page into a bitmap via WM_PRINT Hi, I'm copying the image of a web page into a bitmap by loading the page first into the web browser control (AxSHDocVw.AxWebBrowser) and then sending the WM_PRINT message to the control. Everything works fine except for pages that have Flash animations on them. In those cases the bitmap comes out as blank white. My code is similar to the code in this blog: http://kentb.blogspot.com/2005/03/nice-form.html . I don't think there's anything fundamentally wrong with the code as it works fine for web pages that have no Flash animations. I wonder if anyone has encountered similar problems? I'd be also happy if I could somehow disable the Flash animations via MSHTML if that fixed the problem. Regards, Sami Tag: Smarthclient and crystal rpt viewer Tag: 86033

    - Problems with custom events Browsing through some online tutorials, I've been tryingto add a custom event to an app I'm developing but I'm having a little problem. Simplifying the code down to the following (a form with a button that fires the event): namespace CustomEvent { public delegate void MyEventHandler(object sender, MyEventArgs e); /// <summary> /// Summary description for Form1. /// </summary> public class Form1 : System.Windows.Forms.Form { public event MyEventHandler MyEvent; protected virtual void OnMyEvent(MyEventArgs e) { MyEvent(this, e); } << snip template form code >> private void button1_Click(object sender, System.EventArgs e) { OnMyEvent(new MyEventArgs("Fred")); } } public class MyEventArgs: EventArgs { private string name; public MyEventArgs(string name) { this.name = name; } public string Name { get {return name;} } } } The problem I'm having is that the MyEvent(this, e); call fails in OnMyEvent(...) with the following error: "An unhandled exception of type 'System.NullReferenceException' occurred in CustomEvent.exe Additional information: Object reference not set to an instance of an object." Can anyone explain what I'm doing wrong? Cheers in advance Ant Tag: Smarthclient and crystal rpt viewer Tag: 86032

    - Capturing change to TextBox I want to simply capture changes to a TextBox and perform some processing when the user has edited the text. The TextChanged event fires even while the user is editing the text, but I only want to perform my validation when the user finished editing the text and moves off the field (tab, enter, mouse-click somewhere else, etc). The Validated event fires when the user moves off the field but fires even if the user does not change the text! I know I could save the "before value" of the text in a local variable in the Enter trigger and compare this to the current value in the Leave or Validate trigger but this is messy! There must be a simpler way surely. Someone please help! Tag: Smarthclient and crystal rpt viewer Tag: 86026

    - Label and Button text not drawing (Type your message here) I have a small assembly that displays dialogs for logging in and message boxes if an error occurs. The button text and label text in the dialogs isn't drawing when the form is opened by either Dialog.ShowDialog() or MessageBox.Show(). In the case of a dialog, some of the labels appear and some do not. The button text doesn't appear for either dialogs or message boxes. The text draws correctly in the Designer. I was able to 'repair' the dialogs by deleting the controls and re-adding them to the form in the Designer. I don't have that option in a MessageBox. Anyone seen this behavior before? -------------------------------- From: Don Dusich ----------------------- Posted by a user from .NET 247 (http://www.dotnet247.com/) <Id>N41D2NHa90W/Q0PaoCYfpw==</Id> Tag: Smarthclient and crystal rpt viewer Tag: 86009

    - Refreshing Form on Process Hello, I have a windows application written in VB .NET which pulls a lot of data from different databases into one source. This often takes a long time and therefore I track the progress using a progress bar and a status bar. When the program is running and I use another application the form turns white and doesn't refresh itself until the process is complete. Could anyone advice me/provide a VB example of the best way to keep a windows form refreshed when running, but still restrict the user from setting off another process? Many thanks for your advice.

    - Dangling process, when calling ShowDialog twice from Main hi, i've used jason clarks recommendations for handling unhandled exceptions in my winforms app (http://msdn.microsoft.com/msdnmag/issues/04/06/NET/default.aspx). if an unhandled exception happens, i open up an 'Error-Logger' form, which sends the exception to a web service. here is the relevant code: [STAThread] public static void Main() { try { SubMain(); } catch (Exception e) { HandleUnhandledException(e); } } public static void SubMain() { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(OnUnhandledException); // CLR Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(OnGuiUnhandedException); // Windows Forms Application.Run(new MainForm()); } public static void HandleUnhandledException(Object o) { if(o == null) { MessageBox.Show("An unknown error has occurred", "Error"); return; } Exception ex = o as Exception; if (ex != null) new ErrorLogger(ex).ShowDialog(); } this approach works very well. the problem of a dangling process occurs if the user closes the ErrorLogger form before it has finished reporting the error. A ThreadAbortException happens (which i catch and ignore) in ErrorLogger, and the error logger form closes. if i then close the mainform, the process is left dangling in task manager with no windows open. this only happens if the user kills the errorlogger form. the errorLogger form calls the web service on a worker thread, but i am careful to Abort this thread in Dispose() and Form.Close() and even when the ThreadAbortException happens. is there any way for me to work around this? maybe the application is creating two UI threads because ShowDialog is called twice, and only one of those threads gets properly terminated when the application is closed? thanks for any help tim Tag: Smarthclient and crystal rpt viewer Tag: 85989

    - Using The NativeWindow Class To Draw A GDI Type Circle On Top Of A DataGrid Possibly In The Override OnPaint I have a requirement to put a GDI style circle or rectangle border around the selected row of a datagrid/ It will overlap into the row above and below the selected row. Doing this in a the OnPaint of a subclassed DataGridTextBoxColum dos not seem like a practical way to do it. I have subclassed a DataGrid and overridden the OnPaint as such: protected override void OnPaint(PaintEventArgs pe) { base.OnPaint(pe); // Create pen. Pen blackPen = new Pen(Color.Green, 2); // Create location and size of rectangle. float x = 15.0F; float y = 53.0F; float width = 500.0F; float height = 20.0F; // Draw rectangle to screen. pe.Graphics.DrawRectangle(blackPen, x, y, width, height); } It works but has refresh problems. Last week Bob Powell [MVP] suggested that I use a NativeWindow class to solve this problem. I've just had the time to get back to this and not being a former C++ person, etc., etc., etc. maybe someone can help with this. The MSDN help screen for the NativeWindow class is this link: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformsnativewindowclasstopic.asp It has an example and in the subclassed NativeWindow constructor it creates a button: public MyNativeWindow(Form parent) { ..see help example } Can someone advise me on where my code above that paints the Rectangle should go in this NativeWindow example?

    - Creating DesignerVerbs for a Reflection.Emit-ed class for use in a PropertyGrid Hi, I've hit a bit of a brick wall in my use of the PropertyGrid control. I am writing a Windows Forms application that does the following: - dynamically create a class using Reflection.Emit - the class simply holds a number of properties ("Name", "Description", etc). - pass the class to a PropertyGrid control which then renders the properties for the user to edit. This is all working fine, and I have even added my own Category and Description attributes to the properties which are showing up successfully in the PropertyGrid. My problem is that I would also like to add a couple of DesignerVerbs to the class, so that I can offer "Add Property" and "Remove Property" functions in the PropertyGrid. I have set the CommandsVisibleIfAvailable flag on my PropertyGrid, and attempted to set the Designer attribute on my dynamically-created class. The Designer attribute points to a custom ComponentDesigner class, in which I have defined the DesignerVerbs. However, the verbs are not being shown in the PropertyGrid. I may have a lead in that the Attributes property of my TypeBuilder class still says "NotPublic" after I SetCustomAttribute. But does that mean the contents of the Attributes collection are not public, or that my class' only attribute is "NotPublic"? Any ideas on something I might have missed? Below is some example code, in the hope that it jogs someone's memory! I'd be happy to post anything else that may be relevant. Cheers Lee ********************************************** *** snippet from DynamicCmSchemaCreator.cs *** *** creates the DesignerAttribute using my *** *** custom ComponentDesigner class *** TypeBuilder typeBuilder = moduleBuilder.DefineType ( DynamicType, TypeAttributes.Class, typeof(Component) ); // Apply the Designer attribute, supplying our own ComponentDesign class CustomAttributeBuilder customAttributeBuilder = new CustomAttributeBuilder ( typeof(DesignerAttribute).GetConstructor(new Type[] { typeof(Type) }), new object[] { typeof(DynamicCmSchemaComponentDesigner) } ); typeBuilder.SetCustomAttribute(customAttributeBuilder); ******************************************* *** DynamicCmSchemaComponentDesigner.cs *** *** the componentdesigner I attach to *** *** the dynamic class *** public class DynamicCmSchemaComponentDesigner : ComponentDesigner { private const string AddPropertyVerb = "Add Property"; private const string RemovePropertyVerb = "Remove Property"; private DesignerVerbCollection verbs; private void OnAddPropertyVerb(object sender, EventArgs e) { System.Diagnostics.Debug.WriteLine("Processing Add Property"); } private void OnRemovePropertyVerb(object sender, EventArgs e) { System.Diagnostics.Debug.WriteLine("Processing Remove Property"); } public override DesignerVerbCollection Verbs { get { if (verbs == null) { verbs = new DesignerVerbCollection(); verbs.Add(new DesignerVerb(AddPropertyVerb, new EventHandler(OnAddPropertyVerb))); verbs.Add(new DesignerVerb(RemovePropertyVerb, new EventHandler(OnRemovePropertyVerb))); } return verbs; } } } **************************************** *** snippet from MainForm.cs *** *** creates the dynamic class and *** *** passes it to the propertygrid *** object dynamicCmSchema = DynamicCmSchemaCreator.CreateDynamicCmSchema ( node.CmSchema.Properties ); this.propertyGrid.SelectedObject = dynamicCmSchema; ******************************************* Tag: Smarthclient and crystal rpt viewer Tag: 85969

    - Architectural Guide to Winforms Development? I'm primarily a class library developer, but I've written a few small tools in my day using forms (VB6/Java/Winforms) and my libraries have been used in larger forms apps. The thing is, I've never seen a well architected forms app in my 12-year career and I'm wondering if there is a book or some resource that deals specifically with designing a forms app. In the class library/component world, it's relatively easy to implement design patterns and graceful object-oriented designs, I suppose because we don't have to keep so many balls in the air and visually interact with users. Are there common patterns and designs for forms development? I understand and have implemented simple Model-View-Controller and Model-View designs, but I'd like to know of other designs (are there any?) and how compatible they are with WinForms development. I would love to have a resource that goes deep into some of the common issues with forms like forms management (ie organizaing, caching, reusing), use of dialogs, data encapsulation, messaging between GUI objects, and so on. I'm quite comfortable with the mechanics of WinForms, so I'm looking for something more design-oriented. Thanks for any pointers. Tag: Smarthclient and crystal rpt viewer Tag: 85962

    - Timers and threading Hi, I am writing a program that handles authentication, and based on the user's permission level, can do certain things in the program. However, I want to have a global 10 minute time out in case a user is idle for that amount of time. To do this, I am using a timer from System.Timers. At the end of the 10 minute timeout, I want the timer to call methods within the program to limit access to certain functionality. However, the problem is that the timer is working on a different thread, and so calls to these methods will also be on this thread, which is not the owner thread of the controls I am trying to alter, and so I'm getting an exception. How can I tell the owner thread to manipulate the controls? Thanks! Tag: Smarthclient and crystal rpt viewer Tag: 85952

    - optimize .net app with a lot of graphic background images Hello, I have a winform that looks beautiful. All the panels have bacground images. I even have rollover buttons for the main navigation. My problem is that it loads slower than a "plain" winform app. Also when minimizing the form and switching back to my application it has "blank sections" that occur for a few moments. Right now my application is just a shell, there is no "programming code". All the code has been done in the forms designer except for the rollovers. What can I do to 1) optimize the performance overall of the application 2) make repaints quicker 3) generally run faster Right now the only way I know to "optimize" the application is (a) write efficient code and (b)Setting the "Configuration" to "Release" and (c) setting "Optimize Code" to "true".

    - Toolbar on TerminalServer runninf with 256 colors Hello all together. I have little bit trouble with a Toolbar which i want to use in vb.net. I have placed in Toolbar on my form and added some buttons to it. In addition i have also placed an imagelist with images that are all gifs optimized for 256 color (to be more precisely: i have optimized them so that they fit to the windows-system-color-palette using 256 colors). than i assigned these images to the buttons on my toolbar. So far so good. everything looks as expected in the designer. But when i run the application in a terminal-server-environment which uses 256 colors the images don't look the same as in a normal-environment. they look if they have only 16 colors or somethink like that. So i put one of my images stored in the imagelist on a normal button situated on the form. When i re-run the application in a terminal-server-environment the normal button looks like expected where else the toolbar buttons looks ugly. Can someone please point me to the right direction to get manged it. Or perhaps does somebody has some sample code?

The problem is that the display of the text gets slower and slower as more and more text is added (using .AppendText). Is there a way to limit the text box to some fixed number of lines (or characters) of text such that the first text in would automatically get dropped from the text box when the limit is reached? I've tried using SelectionStart combined with SelectionLength to select and cut the first line of text when the limit is reached, but that gets the vertical scroll bar bouncing up and down as the code bounces between adding new text and deleting old text. This results in even worse performance of the text box. Any thoughts or suggestions? Thanks, Ron Tag: Smarthclient and crystal rpt viewer Tag: 85937

    - 401 error when trying to read my app config (app hosted on webserv I have a windows forms app that I am launching with a url. I worked through the trust issues and it is working well except for one thing. When I try to use the ConfigurationSettings.AppSettings class to read a value from my application config file it fails. The virtual dir is setup for integrated auth only. What happens (according to the iis logs) is the attempt to read the file gets a 401 response, then gives up. Normally this would be followed by one more 401 then a 200 once the client finally sends the correct credentials. This is what shows up for other files such as the .exe and so forth. I assume the difference is that IEexec is handling the authentication challenges for loading the .exe, but what do I need to do so the framework will handle the authentication challenge while using the appsettings method ? BTW if I allow anonymous on the virtual this works just fine. Ideas ? Tim Tag: Smarthclient and crystal rpt viewer Tag: 85931

    - form hide (or visible = false) Hi, In the form's Load event handler I'm trying to hide the form, but still the form is visible although the Visible property is set to false. Only if the ShowInTaskBar property is set to false too, it is not visible. Why? Isn't there a way to hide a form from its Load event handler but to display it still in the task bar? Here is the code: // handler for the Load event private void FrmLifetimeDemo_Load(object sender, System.EventArgs e) { this.Visible = false; this.ShowInTaskbar = false; } -- Ohad Young Medical Informatics Research Center Ben Gurion University Information System Eng Office Phone: 972-8-6477160 Cellular Phone: 972-54-518301 E-Mail: ohadyn@bgumail.bgu.ac.il Tag: Smarthclient and crystal rpt viewer Tag: 85928

    - PrinterSettings.PaperSources Does anyone know how to switch trays(paper source) when printing a multi-page document? Here is some code I have tried, but I can never get the printer to grab from another tray during the print of a document. If I seperate the two calls into Page 1 and Pages 2-4, then the printer will grab from the appropriate tray. To do this, requires I call the objPD.Print two times. This seperates them in the print buffer, which we are trying to avoid doing. Friend WithEvents objPD As System.Drawing.Printing.PrintDocument Private Sub PrintMe() Dim ps As New System.Drawing.Printing.PrinterSettings ps.MaximumPage = 4 ps.MinimumPage = 1 ps.PrintRange = Printing.PrintRange.SomePages ps.FromPage = 1 ps.ToPage = 4 ps.PrinterName = printerName 'Printer name was captured eariler by user objPD.PrinterSettings = ps m_currentPrintingPage = 1 m_lastPrintingPage = 4 objPD.DefaultPageSettings.PaperSource = objPD.PrinterSettings.PaperSources(1) 'goldenrod colored sheet objPD.Print() End Sub 'Then in the printpage event: Private Sub objPD_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles objPD.PrintPage e.HasMorePages = False If m_currentPrintingPage <= m_lastPrintingPage Then If m_currentPrintingPage = 1 Then 'first page gets a goldenrod sheet objPD.DefaultPageSettings.PaperSource = objPD.PrinterSettings.PaperSources(1) 'goldenrod sheet e.PageSettings.PaperSource = objPD.PrinterSettings.PaperSources(1) 'goldenrod sheet 'neither of the two above lines work, either together or seperate Else 'all other sheets in this document get plain white paper objPD.DefaultPageSettings.PaperSource = objPD.PrinterSettings.PaperSources(5) 'White sheet e.PageSettings.PaperSource = objPD.PrinterSettings.PaperSources(5) 'White sheet 'neither of the two above lines work, either together or seperate End If ReportDrawPageNET(e.Graphics) 'create the page that goes to the printer m_currentPrintingPage += 1 If m_currentPrintingPage <= m_lastPrintingPage Then e.HasMorePages = True Else e.HasMorePages = False End If e.Graphics.Dispose() End If End Sub Thanks! -- Todd Acheson Tag: Smarthclient and crystal rpt viewer Tag: 85926

    - FolderBrowserDialog.FolderBrowserDialog does not work on Windows 2 I found out this problem very long time ago. I set FolderBrowserDialog to false but the New Folder button still shows on Windows 2000. At that time, I thought it may be related to Windows 2000 itself and SP3/SP4 would eventually fix it. But at the beta 2 release of .NET FX 2.0, the problem still exists on Windows 2000/SP4. Note that this problem does not exist on Windows XP/2003 (I do not have the chance to test it on Windows 98). Will Microsoft fix this *small* problem? Tag: Smarthclient and crystal rpt viewer Tag: 85920

    - Splash screen? Hi all, I've created a splash screen for an MDI application and moved the main application's entry function in the splash screen's class. Inside the Main(), I run the following: [STAThread] static void Main () { Application.Run (new FormSplash ()); } In the Load event of FormSplash, I start a timer that increases the form's Opacity value and updates a progress bar and a label. Finally, I start another thread to run the MDI form and close the splashscreen: private void FormSplash_Load (object sender, System.EventArgs e) { timer_Refresh.Start(); ... ... // connect to db, initialize some static objects etc... ... // Run main MDI application Thread thread = new Thread (new ThreadStart (FormMain.Start)); thread.IsBackground = false; thread.Start(); this.Close() } The problem is that even if timer is enabled, it doesn't get into the Tick event's implementation, until the splash form is being closed with Close(). Any suggestions? Is there a simpler way to have a splash screen created and shown before the main application's form? Thanks in advance, Pascal Tag: Smarthclient and crystal rpt viewer Tag: 85917

I have the following questions: 1. How do I find information about logical devices? There are functions returning logical drives' names, but no info what they are (floppy, CD-ROM, hard drive) 2. How do I browse the network (if there is one)? Thank you Tag: Smarthclient and crystal rpt viewer Tag: 85911

Basically I want to lump a few different (but related) apps into the one assembly, and have a number of icons in the start menu.

    - Passing Information/address form properties - VB.NET I have a basic question about how do you change the information on a Form from another Form, not a dialog. Example: I have a MDIform which is the startup form for the project. I call a child form to put in setup information which is written to the Registry. As a result I need to update the Text (Title) of the MDIForm and a StatusBar Panel(0) which is also on the MDIFORM. In VB6 this was easy. I has tried using classes but can not seem to get it to work. I can pass to a new instance but not to the current instance. Help Leo Tag: Smarthclient and crystal rpt viewer Tag: 85898

    - Accessing a String Resource It seems like it should be so simple but I'm having trouble with the baseic C# code for accessing a String resource. I need to be able to do this both from a WindowsForms application and a Console application. When I do... ResourceManager RM = new ResourceManager("ProjectName", Assembly.GetExecutingAssembly()); m_ConnString = RM.GetString("ConnectionString"); I get a "MissingManifestResourece Exception" on the GetString() line. But I'm not sure if this is because "ConnectionString" can't be found within the standard Resources.resx file included when one creates a Application Project in VS or if it's because I don't know exactly how to provide the parameters for the ResourceManager constructor. Help? Alex Tag: Smarthclient and crystal rpt viewer Tag: 85897

    - Form.Update in Windows Xp Hello everyone: I'm developing an application that executes a long algorithm and I want to show a progress bar, and every time the progress bar is updated, I also update the main window, so the window refreshes the invalidated areas. I was developing in win2k and everything works fine, but now Im using WinXp, and the form.Update () is ignoring my calls, so the application looks like a big white box and the user can not know where the progress bar is. Is that a bug? (Im afraid it is a feature..) Is there any way to do that without having to create threads or some things like that?? Tag: Smarthclient and crystal rpt viewer Tag: 85894

    - Rich Client Framework (like MFC?) Where is MFC for .NET? I need something ~similar~ for .NET. Please read on... We are embarking on a project for which we need to build a pluggable rich client framework. We have 15 applications which we are going to integrate into a singe common desktop, sort of like the dashboard model of old. We need to have a shell which will act as the host for a bunch of application "widgets". The shelll needs to support things like common UI realizations, shared state (or context) and implments the MVC or PAC (preferred) patterns. We had a bakeoff with Eclipse/ICWT the Java based framework and won - Doh!. Our plan at the time was to use a new MS Block which supported exactly these features, but it has been tied to Whidbey and therefore is not an option for our Oct release. Of course to write this from scratch would also put an Oct release at risk. Anyone know of a third party product which comes close? I already checked out Ghengis and it's the closest thing so far, but is not nearly robust enough. Thanks, curt Tag: Smarthclient and crystal rpt viewer Tag: 85890

    - Reflection and Menu Merging in MDIs We have an MDI application that looks for forms in which a common interface has been implemented. We can instantiate the forms and display them as children of the mdi and use the functionality on them. The problem is that the menus don't show up. They don't even show up on the form itself, much less merge with the mdiparent menus We have changed the modifiers on the menu and on each item in the menu to public so they can be seen outside the assembly. We have tried not making the form an mdichild and using it as a stand-alone application (still instantiated by the mdi, although not as a child). The child form does appear in the 'windows' list as a child of the mdi. Is there any way to make available to the mdi, the menu on a child form instantiated through reflection?
