 - Is there an enumeration for the WM_ messages???? If I overload WndProc(), I'll want a switch() in there to act on different windows WM_ messages like WM_MOUSEMOVE and stuff like that. Trouble is, how do I find the value of these constants? I know, I can hunt around in winuser.h for them, but if I'm a VB or C# guy, that's kind of a roundabout solution. The ".net" way of doing this would be to give me an enum that contained all the values. Is there such a thing? I can't find one. Tag: Borderless form? Tag: 61958

 - System.Security.SecurityException: Request failed. I'm trying to get my Windows form exe to execute from a web server. Everything works fine on the server itself (my local machine), when I go to any other machine, I get this error. I have used the dotnet Trust An Assembly utility to trust the assembly, and I can browse to the server OK (my local machine). Unfortunately our systems administrators have locked down the security in IE so that it's impossible to add trusted sites, or change any of these settings. I can probably get them to change this, but I'd have to be clear in what I needed changing. Can anybody help. All the samples sem to assume you've got full access to the machine.

 - [ANN]unofficial Extensibility Application Block Hi Folks. Look here for the full details: http://weblogs.asp.net/rosherove/posts/39484.aspx and here for the download: http://workspaces.gotdotnet.com/eap in a few sentences: This block allows you to incorporate plugins into your application with ease. It also allows to easily create plugins for your application if it uses this framework. intro: Extensibility Application Block overview: One of the demands from a successful application is the abilityto easily adept to the needs of its users if and when they change (and they do). Many times, the required changed, or extra features that need to be added require not only pure development work, but also re-compilation of some or all of the application binaries (this discussion does not include web applications, only winform applications). To avoid having to go through this sometimes painful process just to add a simple feature, or fix a simple bug, a new need has grown - to allow extending an existing application without the need to recompile it or even without the help of the original developer. This is how what we know today as Add-ins and plugins were born. When we moved into the world of .Net, we still have the ability to write applications that can be extended by others. However, there is no clear path, a common way, to design and implement such abilities into .Net applications. If you were to go today and try to build an extensible application, you'll be faced with a myriad of articles and HOW-TOs, each explaining the story a little bit differently than it's predecessor. This Application block was created so that we can start and retain a common ground for how such abilities should be built. So that it can be both easy to understand and powerful enough as to be used by the most demanding applications. The solution I present here is based on my experience writing extensible applications in .Net and on all the things I learned while trying to figure out the best way to achieve specific abilities while trying to maintain a generic approach. How does it work? There are 3 basic principles that need to be implemented in order for an application to have plugins: 1. The application needs a way to recognize and communicate with the plugins 2. The Plugins need a way to talk (or sometimes control) the application in which they are hosted 3. The plugins need to be recognized and loaded at runtime into the host application 1. The application needs a way to recognize and communicate with the plugins This application block solves this problem by providing a common interface that all plugins must implement:IPlugin. The principle is actually very simple: Let's say I have a text editing application to which I would like people to be able to add plugins. These plugins should be able to talk to the application in which they reside, AND the application should be able to talk to them. However, since the application does not know in advance what plugins may be available (some of them may only be created in the future!) the application cannot have a direct reference on any specific DLL or class. It needs to support ANY CLASS but it needs to be able to talk to it on pre-known terms. This paradox is solved by the using a COMMON INTERFACE that both the plug in and the application know. This interface is declared in a separate assembly and both the plug in and the application have a reference to that assembly. This interface is what our application will use to communicate with the plug in. Any plug in that will want to attach itself to the app will have to implement this interface or otherwise we won't even try to load it. This interface is called (in this application block) IPlugin. 2. The Plugins need a way to talk (or sometimes control) the application in which they are hosted This application block solves this problem by providing a base class called AppContext. To the Plugins, AppContext is their one and only link to the outside world. Anything they need to do, anything they need to know, they do it through this class. The host application will hold a class derived from AppContext which has specific methods and properties which should be shared with the plugins. the IPlugin interface contains an Init Method which passes an AppContext instance into the plug in, allowing it to hold a reference to it and using it for what it needs. For example, For an Editor application, We can have an EditorContext class which exposes events such as TextChanged and properties such as SelectedText and so on. The plugins can use these properties to manipulate their outside environment . It all depends on how much the developer decides to expose to the plugins using the AppContext class. The AppContext class is also the class that will load and unload the plugins when the application starts and finishes, but for that it uses yet another class from the application block - the PluginProvider classes which I'll now discuss in the next paragraph. 3. The plugins need to be recognized and loaded at runtime into the host application There are many ways in which one can organize and recognize the plugins that their application needs to load. Some prefer to dynamically search all the DLLs in the app directory and find classes that implement the IPlugin Interface. Some prefer to list the required plugins and their type inside the application config file. Some might have a whole different way of doing this which no one has ever thought of before. This application block is built to support whatever method you choose to load your plugins, and it also provides a couple of implementations right off the bat so you can get up and running in no time with your new application. In the extensibility block there are special objects for which the only purpose in life if to find and load plugins. These are called Plugin Providers. Each plug in provider must implement the IPluginProvider interface. There are several providers already build for you. These include the XmlFilePluginProvider, SectionHandlerPluginProvider and DynamicFindPluginProvider. Each of these implements searching for plugins in a totally different way, but because they all support the same interface, they all return a collection of IPlugin object when they are done allowing you to simply choose the method in which to search. Don't find anything you like in there? Feel like you need an extra feature? Simple implement the IPluginProvider interface in your own class and you're free to go. -- Roy Osherove weblog: http://www.iserializable.com Tag: Borderless form? Tag: 61925

 - Textbox-level validation Folks, I have a C# WinForms app, and I am doing some validation of text boxes and their contents. So far, I've used the TextBox1_Leave event - if the focus goes away from the textbox, I check for certain conditions (not empty, valid entry etc.). This works okay so far - but in some cases, I'd like to skip that validation, e.g. when the user clicks on the "Cancel" button. But how can I "foresee" that the user has clicked the Cancel button, inside my TextBox1_Leave event?? In Delphi, we used to be able to inspect a property "ActiveControl" which was set to the button that had been clicked - based on that info, I was able to determine whether or not I wanted to apply my validation. I don't seem to find anything similar in C# / .NET - I do have an "ActiveControl" property, but that is still set to my text box, as long as I'm still on it..... Any way to achieve what I'm trying to do without major kludges?? Marc ================================================================ Marc Scheuner May The Source Be With You!

 - Scope of form variables... This may sound like a dumb question, but I am hoping someone might comment on it.... Consider the following method (assuming that Form1 is a class derived from System.Windows.Forms.Form) : private void MyMethod() { int i = 1; Form1 myForm = new Form1(); myForm.Show(); } Both of the variables, i and myForm, are local variables that should go out of scope when the method is finished executing. But the myForm variable continues to live on. Is this correct? Why is the scope of form variables different than the scope of other types? Tag: Borderless form? Tag: 61889

 - Main Form Unresponsive I'm building a custom install program that allows the user to select which assemblies get installed. In creating the prototype I am encountering a situation where the main form will not accept user input after the installation is complete. In my form, pressing the 'Install' button runs the following method: public override bool Install() { IDictionary savedState = new Hashtable(); System.Configuration.Install.AssemblyInstaller ai = new System.Configuration.Install.AssemblyInstaller(); try { ai.Path = "testassembly.dll"; ai.UseNewContext = true; ai.Install(savedState); ai.Commit(savedState); ai.Dispose(); return true; } catch (Exception e) { return false; } } My trivial installer class is the only class in the "testassembly.dll" named above: [RunInstaller(true)] public class Installer1 : System.Configuration.Install.Installer { public Installer1() { } public override void Install(IDictionary stateSaver) { base.Install (stateSaver); MessageBox.Show("Installing", "TestAssembly"); } public override void Uninstall(IDictionary savedState) { base.Uninstall (savedState); MessageBox.Show("Installing", "TestAssembly"); } } After the install MessageBox is dismissed, the main form gets updated (progress bar goes away and a 'Done' button is made visible) correctly, but when I try to either click the 'Done' button to exit the app, or close the form, nothing happens. If I remove the MessageBox from the installer class, then everything works correctly and I can exit the app, so I assume that there is some sort of forms or event loop issue going on, but I have not been able to figure it out. Anyone have any ideas? Matt Tag: Borderless form? Tag: 61883

 - Main Form's Display chops Right Side & Bottom Hello, It seems that on a certain machine (i.e. Dell Dimension 4500S) when the main form is displayed (it initially comes up maximized, and AutoScale is True per the default - not that I truly grasp its significance) parts of the right and bottom portions of the form are not being displayed at all in the window. They seem to have been truncated from the display. I have a textbox that is located (and anchored) on the far right-hand side of the form and when it comes up more than half of the text is just chopped off (a good 2 logical inches or so). The bottom of the form has two rows of icons (24x24) that don't show up at all (these icons are also anchored to the bottom of the form). You can't ever get the form to show any of the "lost" area either (ie. by resizing, minimizing, maximizing, etc.). Has anyone seen this behavior at all or has any ideas as to what is causing this behavior? Is there some known issues with cetain computer's video drivers (this Dell Dimensions uses an Intel video driver) and .NET. After looking around on the net I haven't seen this addressed. On this particular machine "normal" apps seem to work fine and this is the first .NET form application it's ever seen. Thanks for any help/insight, JB Tag: Borderless form? Tag: 61878

 - Maximum height of windows form Hi, I am trying to set the height of a form in the VS .net IDE, and somehow seem unable to set the height beyond 780. I have set the autoscale and autoscroll properties to true, and the Miniumn size and maximum size are set to 0,0 each. I was under the impression that with these settings I could make the form as big as I wanted, and could get the scrollbars automatically when needed. However this doesnt seem to be happening. The height gets reset to 780 if i type in anything bigger than that. Am I missing something here ? Does anyone have an idea why I see such behavior ?

 - Problems with MessageBox.Show I'm experiencing a problem where I have a non-modal toolwindow that contains a control derived from System.Windows.Forms.ComboBox displayed in an MDI application. Whenever a .NET message box is displayed in the application the derived combo boxes on the toolwindow appear to lose their base control, i.e. base.WndProc(ref m) in the derived control's WndProc results in a NullReferenceException. Admittedly this could be a problem with the derived controls, however after looking at how System.Windows.Forms.MessageBox works it seems like there are some "oddities". Also, if I call the Win32 MessageBox function directly via p/invoke, specifying the correct owner window, then everything works fine. Here is the section of System.Windows.Forms.MessageBox (ShowCore) that I've been looking at: if ((owner != null) && ((options & 2228224) != 0)) throw new ArgumentException(SR.GetString("CantShowMBServiceWithOwner"), "style"); IntSecurity.SafeSubWindows.Demand(); num1 = (((buttons | icon) | defaultButton) | options); ptr1 = IntPtr.Zero; if ((options & 2228224) == 0) { if (owner == null) ptr1 = UnsafeNativeMethods.GetActiveWindow(); else ptr1 = owner.Handle; } Application.BeginModalMessageLoop(); result1 = MessageBox.Win32ToDialogResult(SafeNativeMethods.MessageBox(new HandleRef(owner, ptr1), text, caption, num1)); Application.EndModalMessageLoop(); return result1; The value of 2228224 corresponds to MessageBoxOptions.DefaultDesktopOnly | MessageBoxOptions.ServiceNotification. The interesting thing here is that the owner parameter is always ignored since owner must be null when options contains the above flags. If owner is not null, the handle is never retrieved because options cannot also contain the above flags and therefore ptr1 remains as IntPtr.Zero. The other interesting thing is the BeginModalMessageLoop/EndModalMessageLoop block. It appears as though this disables all windows in the current thread, although I haven't looked at this too deeply, and this further implies that the owner parameter plays no part in establishing modality. Does anyone have any thoughts on this, particularly with reference to the fact that the BeginModalMessageLoop/EndModalMessageLoop block appears to be causing severe problems for my non-modal windows? A single call to the Win32 MessageBox function with a correctly specified owner window does not exhibit the same problems. TIA. -- Kevin Westhead Tag: Borderless form? Tag: 61859

 - Custom painting in TextBox Hello I have a new class which inherits from TextBox and implements a numeric textbox which have to allow the user to input signed numbers. The control of key input is OK. The problem is how to implement the display of the sign character. I am planning to enabled this feature by allowing the pressing of plus and minus keys (+ and -). When the user hits the minus key, the negative sign appears at the left side of the number; when he hits the plus key, no sign is shown in the textbox. This means that changing the left margin of the textbox is not enough to make this feature work because the textbox's default alignment is at the right side, and, in addition, the textbox must allows the programmer to change the text's alignment. I do not want to include the negative sign character in the text because of the lot of code I will have to write in order to control user key hitting. I am thinking about just painting the negative sign character at the left side of the text, without including it in the text, by handling some paint event. Does somebody knows some guidelines on how can I do this? Celio C Jr Tag: Borderless form? Tag: 61835

 - System.Windows.Forms.MdiClient+ControlCollection not serializable. Scenario: --------- I have an Explorer style application. The app hosts other win forms by making them MDI children, removing border / control box / minimize / maximize, and setting the form's Dock property to Fill. I have recently upgraded my application in the following way: ------------------------------------------------------------- The MDI child forms are now contained within separate dynmically loaded assemblies. My host application creates a new application domain to load the assemblies into. A new instance of the child form is created within the context of the new application domain, then my host application communicates with that object via Remoting (cross AppDomains). Problem: --------- I can no longer set the MDI Child form's MdiParent property to my host app because my host app's ControlCollection is not serializable, and I get a SerializationException thrown. I either need to: - Find a way to set my remote MDI child's "MdiParent" property, or - Use the Win32 Api to create the child form as an MDI Child without adding it to my host application's MdiChildren collection.

I have done the standard subscribing to the event, and connecting the event handlers. But nothing happens. Any help would be greatly appeciated. Thanks, Mark Within a procedure: daPersonPhone.RowUpdated +=new SqlRowUpdatedEventHandler(OnRowUpdated); daPersonPhone.RowUpdating +=new SqlRowUpdatingEventHandler(OnRowUpdating); The event handlers: private void OnRowUpdated(object sender, SqlRowUpdatedEventArgs e) { if (e.StatementType == StatementType.Insert) { if (e.RecordsAffected == 1) { int newOrderID = (int)e.Row["OrderID"]; DataRow newRow = dsOriginal.Tables["Phone"].Rows.Find(dummyPhoneID); newRow["OrderID"] = newOrderID; } } } private void OnRowUpdating(object sender, SqlRowUpdatingEventArgs e) { if (e.StatementType == StatementType.Insert) dummyPhoneID = (int)e.Row["PhoneID", DataRowVersion.Current]; } ********************************************************************** Sent via Fuzzy Software @ http://www.fuzzysoftware.com/ Comprehensive, categorised, searchable collection of links to ASP & ASP.NET resources...

 - IDisposable, using(), RAII and structs [Discussion] Last night I had several thought about RAII and want to discuss a bit. Why doesn't CSharp support destructors in structs? Wouldn't that make RAII possible like in C++? When the struct goes out of scope, the dtor could be immediately be called (no GC needed). For that, you don't have to declare the whole File class as a struct (which would be not good for performance when File has a lot of data-members). Instead creating a thin wrapper would be a good solution: public struct MyFile { File f; public MyFile(string p) { f=new File(p); } ~MyFile() { f.Close(); } } That would do it. I have a second though which got through my mind. What about introducing an interface which is recognized by the compiler and forces usage of the using() statement. public interface IDisposableForce : IDisposable{} A second possibility could be declaring an attribute which marks IDisposable-implementing-classes wheather using() should be mandatory or at least suggested. enum WarnLevel {NoWarn,WarnLvl1,WarnLvl2,WarnLvl3,WarnLvl4,GenerateError}; class UsingAttribute{UsingAttribute(WarnLevel w){}} [Using(WarnLvl3)] // that means if warnlevel 3 or higher is set a warning is issued when this class is used without using()-statement public class MyFile : File { public class MyFile(string p) :base(p){} } What do you think? -- cody [Freeware, Games and Humor] www.deutronium.de.vu || www.deutronium.tk Tag: Borderless form?

 - [urgent] Message Box is non-modal in VB! Hi, In some situation, the message box can not be shown in modal mode. Please drop a DateTimePicker control on a Form (VB project), show a message box in the ValueChanged event, as below snippet. Now run the form and drop down the calendar, select a date to let the event fire, after the message box shown, we can still activate the form background. This happens whatever MsgBoxStyle is specified even as MsgBoxStyle.SystemModal. Private Sub DateTimePicker1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged MsgBox("DateTimePicker1_ValueChanged", MsgBoxStyle.ApplicationModal) End Sub The same scenario could be reproduced in a C# project, but I could pass it if by specifying the Form as the owner of the message box, as below code. private void dateTimePicker1_ValueChanged(object sender, System.EventArgs e) { MessageBox.Show(this, "dateTimePicker1_ValueChanged"); } Is something wrong in the message box method in VB? -jason Tag: Borderless form?

 - Button.TextAlign bug? Hi, I'm using C# and VS.net 2003. When adding a button to a form using the designer, the default TextAlign value is always set to MiddleCenter (which is fine). However, if I change the font to be bold, the text is no longer center- aligned, it is always a bit off to the right, more or less depending on the string value. The TextAlign property is still MiddleCenter though. Is this a known bug? Thanks, Henrik Tag: Borderless form? Tag: 61711

 - A From won't close (c#) Hello everyone, I have main application form (child of System.Windows.Forms.Form) that hosts quite a number of different visual components. Some time after working with those components, the form refuses to be closed - I click menu item that invokes Form.Close() method, I click 'close' icon on the caption of the window (form) - nothing happens. No event comes to Form_Closing(Object, CancelEventArgs) method either. I'm at a loss how to even start debugging this situation and I would appreciate any suggestions.

 - How to force window to Maximize Hi, I would like to force my application to maximize when it is launched. I have tried this by setting the WindowState in the designer at runtime, and have also tried executing WindowState = FormWindowState.Normal The form does open maximized but it does not correctly maximize to the Windows taskbar...the bottom of the form is lost under the taskbar. If I use the form control menu to set the form to normal and then back to maximized, it correctly fits into the available desktop area, only going up to the top of the taskbar. Any ideas why??? Also I want to stop the user setting the window state to normal - I either want it maximized or minimized, but never normal. If the user double-clicks the Window title it does set the window state to normal. Is there an easy way to prevent this from happening??? Many thanks. Tag: Borderless form? Tag: 61704

 - Check for illegal char in DataGridTextBoxColumn Hi all, need some help in taking the right approach to solve this problem. I have a DataGrid bound to a DataTable. I need the user to enter only numerical values and decimal. I did override the ProcessCmdKey of DataGrid. I'm capturing Enter, Tab, directinal and other keys. If the user enters an invalid key, I need to prompt him. But, for this I'll need to map all the other keys to be invalid in my code. Is there any other slick way of doing this. Code attached. protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { const int WM_KEYDOWN = 0x100; const int WM_SYSKEYDOWN = 0x104; int rowNum = dGInput.CurrentCell.RowNumber; int colNum = dGInput.CurrentCell.ColumnNumber; if ((colNum == 2) || (colNum == 5)) { if ((msg.Msg == WM_KEYDOWN) || (msg.Msg == WM_SYSKEYDOWN)) { switch(keyData) { case Keys.D0: case Keys.D1: case Keys.D2: case Keys.D3: case Keys.D4: case Keys.D5: case Keys.D6: case Keys.D7: case Keys.D8: case Keys.D9: case Keys.NumPad0: case Keys.NumPad1: case Keys.NumPad2: case Keys.NumPad3: case Keys.NumPad4: case Keys.NumPad5: case Keys.NumPad6: case Keys.NumPad7: case Keys.NumPad8: case Keys.NumPad9: case Keys.Decimal: case Keys.OemPeriod: break; case Keys.Back: break; case Keys.Down: case Keys.Up: case Keys.Left: case Keys.Right: case Keys.Enter: case Keys.Tab: UpdateDataGridCell(rowNum,colNum); break; default: MessageBox.Show("Invalid character","Error"); break; } } } Tag: Borderless form?

I would like to create a MFC project (preferable using the
Wizard) that has a borderless, menuless window as the main
form. Unchecking basically everything in the Wizard still
gives me a border and a menu bar. How do I make it
borderless & menuless?

Thank you,
