    - Datagrid TableStyle I have two grids, two datatables, and a relation object set up in a VB.net windows form. It is in a master detail set up so that the first grid is mapped to the first table via the datasource property. The second grid is mapped to the first table also but the datamemeber is set to the relation object. So that when a row in the first grid is clicked the second grid automatically displays the data associated with that the selected record. This is great and all works well. The issue I am having is that when I build the table style for the second grid it never gets used. I am setting the mapping name of the tablestyle to try and point it to the appropriate table in the grid, only no matter what I map it to, and I have tried all three elements datatable1, datatable2, and relation object, it doesn't seem to format the grid. I even read somewhere to try datatable.relation and that did not work either. Any ideas? Tag: How to implement licensing to commercial software Tag: 88317

    - Parent-Child Relations and Strange ForeignKey problem Here's the deal (simplified): I have a Typed dataset with 2 tables Parent (ID, ParentName) and Child (ID, ParentID, ChildName). ParentID in Child is an FK (ParentChildFK) to the Parent table and is defined with cascase updating and deleting. The ID fields are defined as autoincrement with a step of -1 and a seed of -1. On a Winodws Form, I have 2 datagrids dgMaster and dgDetail. dgMaster is bound to the Parent table and dgDetail is bound to the Parent table and the ParentChildFK datamember. Adding/Updating rows in the grids works great as long as things are done in a certain order. If you: 1. Add a new row to the parent. 2. Add any child rows 3. Save. it works just fine. The new child rows have the proper new ID's that were returned from the database during the data inserts. However, if you: 1. Add a parent record 2. Save 3. Add a child row you receive an error from the datagrid saying that the ForeignKeyConstraint was violated because the value, e.g. -1, does not exist in the parent table. The parent row now has a positive, actual ID, but the child grid or currecncy manager didn't seem to get the message that it should be using the new ID for any new rows. Anyone have any ideas on how to resolve this? Thanks Tag: How to implement licensing to commercial software Tag: 88308

    - [C# .NET] blocking refreshing application's view Hello, I am developing an application written in C# .NET. E.g., there is a button when which I click on, "visible" of a few labels, textboxes are set to false, and "visible" of a few others are set to true. During this short operation, I can see components which are dissapearing and appearing flickering. I would like to avoid flickering. Is it possible to stop refreshing view of application, then hide and show contols I want, and finally refresh view? If so, how to do this? Maybe, there is any better method to achieve my purpose?

    - Deriving from WebBrowserSite I am trying to use the .NET 2.0 Beta 2 WebBrowser control and customize the IDocHostUIHandler as MSDN states: "...implement classes that inherit from the System.Windows.Forms.WebBrowser and System.Windows.Forms.WebBrowser.WebBrowserSite classes. The unmanaged WebBrowser ActiveX control uses the protected System.Windows.Forms.WebBrowser.CreateWebBrowserSiteBase method to retrieve extensibility interfaces implemented by the System.Windows.Forms.WebBrowser.WebBrowserSite class. Override the System.Windows.Forms.WebBrowser.CreateWebBrowserSiteBase method to return an instance of your own class that inherits from the System.Windows.Forms.WebBrowser.WebBrowserSite class. The System.Windows.Forms.WebBrowser.WebBrowserSite class provides a default implementations of the IDocHostUIHandler OLE interface. You can provide your own implementation of this interface or implement any other WebBrowser ActiveX control interface in order to customize the behavior of the control. ... Note If you provide your own implementation for any IDocHostUIHandler members, you must implement all the members of that interface." Here are snippets of the relevant code: [ComImport, InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("bd3f23c0-d43e-11cf-893b-00aa00bdce1a")] public interface IDocHostUIHandler { [return: MarshalAs(UnmanagedType.I4)] [PreserveSig] int EnableModeless([In, MarshalAs(UnmanagedType.Bool)] bool fEnable); . . . } public class ExtendedWebBrowser : WebBrowser { protected class ExtendedWebBrowserSite : WebBrowser.WebBrowserSite, IDocHostUIHandler { public ExtendedWebBrowserSite(WebBrowser host) : base(host) { } int IDocHostUIHandler.EnableModeless(bool fEnable) { return -2147467263; } . . . } protected override WebBrowserSiteBase CreateWebBrowserSiteBase() { return new ExtendedWebBrowserSite(this); } . . . } The problem is that the ExtendedWebBrowserSite IDocHostUIHandler interface methods are never called. When I tried switching to the IDocHostUIHandler2 interface, the one method that IDocHostUIHandler2 adds was called, but none of the IDocHostUIHandler methods were. I assume this is because WebBrowser.WebBrowserSite exposes the IDocHostUIHandler interface. So, how do you override the IDocHostUIHandler COM interface exposed by the base class?

    - updating database schema on client machine during upgrade/install We have a smart client application with an embedded MS Access database. As we put out auto-updates for the application, at some point we also need to update the Access database schema that's on the client. This would involve backing up the user's existing data, installing the new database schema and then copying user's data back into the new schema. Can anyone recommend best ways to do this? Either writing our own code or possibly looking at 3rd party tools who may provide this functionality. Thank you! Tag: How to implement licensing to commercial software Tag: 88285

    - Bug in MeasureString ? Hi, I noticed a little problem with the Graphics.MeasureString-Function: I have a Textline, which contains Tabs. I use a StringFormat-Object, which represents the TabStops. The DrawString-Method calculates the Tabs in the text correctly. But MeasureString ignores them. I'm using the function as following: Dim w As Single = g.MeasureString(MyText, Me.Font, New PointF(x, y), MyStringFormat).Width x,y contains exactly the Drawing-Position of MyText (otherwise I would see this in DrawString). And MyStringFormat stands for an GenericTypographic -Object, which I'm using in the whole project for all Drawing-Operations. It's extended with the Tabstopps. Any suggestions?

    - way to automatically Debug.Writeline every function/event thru reflection?

    - RichTextBox: Selection problem... I have a few problem with selection (on Rtf text): - 1. I have menu doing things (for example setting all to bold), so I memorize the current selection with SelectiionStart & SelectionLength, SelectAll(),apply my style, then reset the selection with the original values of SelectionStart & Lenght. However it's not the same text whihc is selected?!! (it's usually more..). How could I fix that? - 2. When I change selection (like with SelectAll()) The RichTextBox scroll to the end. very annoying for the user to see its text moving for no reason (because I selectAll() just for the sake of setting the style, then I revert the selection, the user don't see that)!

    - Win32Execption: The operation completed successfuly Hello developers. This is not my day. I working with a C# WinForms application, I have about 200 hundred WinForms, they are most of them working as I need. But now when I tried to open (not run) one of them in the designer, it take a lot of time (about 45 second) and almost all the time my visual Studio 2003 IDE bring a lot of errors, some of them: 1- Win32Execption: The operation completed successfully 2- Unknown error (0x0) 3- An Error has occurred with the C # compiler is unable to report due to low memory or possible heap corruption. It is recommended that you save al files, close and restart visual studio The visual studio has to be close from the task manager (totally unresponsive) As far I tied to understand what is happening I found that the particular form has 14 typed datasets, and if I take them out of my form it have a normal behavior (of course, my form get a lot of errors), I put them back one by one and the performance get worse and finaly get the same set of errors. And not a particular dataset to blame. My development Laptop have a Pentium M processor 2 Ghz, 1 GB of RAM, and a big and fast H.D. with more than 50 % free space, running windows XP SP2 (firewall enable), McAffe antivirus, MS Anti SpyWare, all the Security updates and framework 1.1 SP1.

    - Creaing a wizard form Hi all, I recently moved from developing windows apps with Borland Builder to Visual studio.net, With the Borland product I used to create wizards using a tabcontrol, I would then add the pages i required and make the tab for each page invisible, then when the user pressed next or back i would move to the next or previous tab respectively. Since the tabs were invisible they could not see them to click on them and it worked really well. Now I need to create a wizard in a .net app using c#, I put a tabcontrol on my form and added a few pages to it but I can't seem to hide the tabs, I've googled and found that you could remove the pages and only add the one you wanted to view but this would still leave a tab at the top of the form that they could see. Is there a way round this or is there a better way to create a wizard than this using .net and c#? TIA Joe Tag: How to implement licensing to commercial software Tag: 88230

    - Databinding and saving changes (if any) to new row Hi there! I am new to databinding in .Net and I think I am going to get crazy... What I need to do is this: 1) Create a new form for the user to enter a new Product 2) Save changes (if any) when the user closes the form But I still couldn't get what I want, even after searching in Google. Anyone can give me a pointer/hint? Here is the details: 1) The form FormProduct (in which textboxes are bound) gets loaded: private void FormProduct_Load(object sender, System.EventArgs e) { cmProduct = (CurrencyManager)BindingContext[dsProduct,"Products"]; LoadData(); cmProduct.AddNew(); } 2) Users either enter something or just close the form 3) Before closing the form, save any changes (I am stuck here): private void FormProduct_Closing(object sender, System.ComponentModel.CancelEventArgs e) { cmProduct.EndCurrentEdit(); // Saw this in several places already if(dsProduct.HasChanges()) SaveData(); } The problem is this: if I don't call cmProduct.EndCurrentEdit(), then changes will not be detected. But if the user hasn't entered anything, they just close the form (like a cancel), dsProduct.HasChanges() will return true (because we added a row in the dataset). Any solution?

    - Don't use the object: ActiveForm unless you check it for null each Don't use the object: ActiveForm unless you check it for null each time you do. This object is in my opinion flawed and not all that useful since it becomes null when the form loses focus. I am posting this warning lest you too fall into the trap of using the ActiveForm.refresh() method instead of the tnis.refresh(); method. They are not the same and you may or maynot find your program crashing because you did not first check each time you call the refresh method associated with the object again try not to use ActiveForm object and instead use the this object of the form or the actual form itself. I think this is a bad design for ActiveForm object. Bottom line is do not use it unless you are absolutely forced to. Instead use the this.object Here is the original error message I ultimately solved: System.NullReferenceException: Object reference not set to an instance of an object Tag: How to implement licensing to commercial software Tag: 88209

    - ANN: Advanced auto-layout panels plus XAML-style interpreter for 1.1 We have released a library containing a couple of automatic layout controls targetted at .Net 1.1 similar to the the FlowLayoutPanel and TableLayoutPanel in Avalon. Also packaged with these are a basic XAML-style interpreter which works well with existing Windows.Forms controls. These are useful for: - creating resolution-independent applications (especially for those who are long-sighted) - internationalisation (automatic static text translation included in the interpreter) - allowing you to create central visual style rules for an application via XSLT processing of XML script files.

    - Creating a localized control In my application, I am providing a plugin capability by using an interface to specify what the plugin should do. One of the functions is 'CreateConfigurationControl' which returns a UserControl. I am now trying to localize the application, and I'm setting the Thread.CurrentThread.CurrentCulture and CurrentUICulture objects as the very first thing in my Main(). The forms that are created normally are all appearing as their localized versions, but the control that I receive from the CreateConfigurationControl is not, even though there is a localized version defined. In order to actually create the control, I've tried a simple 'new ConfigControl()' and Activator.CreateInstance, passing Thread.CurrentThread.CurrentUICulture to the appropriate version of CreateInstance(Type, BindingFlags, Binder, object[], CultureInfo), but I still get back the default English version... Any suggestions on what I might be doing wrong, or if there is an easier way to guarantee that I get back the correct localized version of my control? -mdb Tag: How to implement licensing to commercial software Tag: 88203

    - Login windows -> Child form, strange behaviour on minimize Hi all, I've got a typical windows form application with a login form, when I login, the login form will be hidden and a new window will appear. For this, I'm using .Show() method, and not .ShowDialog() because there's a chance of reloading a different ini file during login and I want to allow the user to reuse the login form (and it's credentials), and when the user reloads the login form will became visible and the the other window will became hidden. If he really tries to login again then I will kill the new window and create a new one. This all works fine, the problem happens when I try to minimize the login form, a small box appears in the left corner just like a mdi window when we minimize it on the main form. I would like for this "box" not to appear, and the form simply disapears and when I press the on the icon of the taskbar the window would appear again, just like any windows form application.

    - Add image to a control...reposted from languages.vb I originally asked this in languages.vb, and someone there suggested I post it here instead. The requirement I've been tasked with is to have a textbox that has an image in it (a magnifying glass) always on the right side of the textbox, but still in the edit portion. The image should be BEHIND the text, and if clicked on then would fire an event. The suggestion I got from the other group (Carlos J. Quintero, the illustrious maker of MZ-Tools) was to make it an ownerdrawn textbox. He said that all I'd probably need to care about would be the paint event and the click event. In VB6 I'd subclass the textbox and watch for the WM_PAINT message, but in .Net I have NO idea where to start on this. Can someone point me in the right direction? Thanks.

This means that a line of xml might have its color changed several times. I thought it had to do with the changing colors but when i commented that code out it still beeped. If i write the entire line without substringing it together i get no beeps. It only seems to happen when i break the line up and substring it back together. example: the True part will beep but the false part will not. Color changing has been omitted since it's not a factor. if (true) { rtb1.SelectedText = line.Substring(0,10); // originally set color to black rtb1.SelectedText = line.Substring(11,10); // changed color to red rtb1.SelectedText = line.Substring(21,10) + "\r\n"; // changed back to black } else { rtb1.SelectedText = line + "\r\n"; } Anyone know why this happens and is there a way to stop it?

    - Multithreaded WinForms question My application's form is handling an event raised from a worker thread in another object. In the event handler I want to call a sub procedure that does a number of things and among those things is accessing controls on the form. This sub procedure normally has been called from the Click event procedure of a button on the form so there haven't been any issues with accessing controls from outside the UI thread. Now I have to consider this. I could create delegates for all the procedures I need to Invoke on the controls but I was hoping there was a simpler way. Is there any way to force the UI thread to call a sub procedure without using Control.Invoke ()? For example: Private myObj As MyObject Private Sub MainForm_Load ... ... AddHandler myObj.SomeEvent, AddressOf MyObject_SomeEvent ... End Sub Private Sub MyObject_SomeEvent(ByVal whatever As Integer) ' SomeEvent is raised by a worker thread in MyObject. ' How can I force the UI thread to call SomeProcedure ' from here so I don't have to litter the SomeProcedure ' Sub with If...Then...Else structures testing ' Control.InvokeRequired() and calling Control.Invoke() ' with various custom Delegates that I have to create? End Sub Private Sub SomeProcedure(ByVal whatever As Integer) ... Do Stuff SomeTextBox.Text = "Gooney Goo Goo" ... End Sub Hopefully I'm making sense here. I may be a little confused and not realize it yet. Joel Moore Tag: How to implement licensing to commercial software Tag: 88185

I am developing a commercial software app in VB.Net for a client and I need
to implement licensing for the software similar to the licensing in Microsoft
Office (requires product key,etc.). Are there some classes in the .Net
framework that provide licensing functionality and product key creation?

Thanks!
Jason

Absolutely!

Check out the following:

Applications Licensing using the .NET Framework
http://www.developer.com/net/net/article.php/11087_3074001_1

For more advanced licensing scenarios, you might also want to take a look at
Xheo Licensing (http://www.xheo.com).

Good luck,
