    - Change value in bound ctrl when value of another bound ctrl change I have been developing WinForms apps in .NET for several years and have never discovered a good solution to this newbish problem. I frequently encounter a situation where I want to change the value of a control when the user changes the value of some other control and both controls are bound to the same row in a DataTable. For example, say I have a combobox of statuses and a textbox for comments but comments are not applicable for certain statuses. When the user selects one of these statuses I want to set the text of the textbox to an empty string. So I add a handler to the combobox's SelectedValueChanged event and set the TextBox's Text property to an empty string. Doing this seems to cause unpredictable behavior. Sometimes I get an empty textbox but the combobox is changed back to its original value and other times the textbox is not cleared. I assume one change gets pushed to the dataset and triggers a refresh of the controls from the dataset but I'm not really sure. I have worked around this by clearing the textbox when the combobox loses focus but users are never happy with this solution. Having encountered this problem again I thought I would see if anyone can tell me the "right" way to do this. Tag: Context Menu for ActiveX control in VB.NET Tag: 89071

    - PropertyGrid steals focus Hi, I have a MDI child Form that contains a couple of custom controls (both Panel based viewers), a DataGrid, and a PropertyGrid. Try as I might to have the DataGrid receive focus when the MDI child Form is displayed, the PropertyGrid always grabs it. I have registered an event handler for the MDI child Form's Load event and VisibleChanged event and in both have tried to have the DataGrid request focus and set the CurrentCell to (0,0). This has not worked. Any ideas? Thanks. Tag: Context Menu for ActiveX control in VB.NET Tag: 89068

    - How to initialize hidden columns for newly added rows ? I want to allow the user to add new rows. Not all columns from the bound data tabled are mapped (i.e. there are hidden columns). But some of those columns do not allow null. When I add a new row I get an exception: A first chance exception of type 'System.Data.NoNullAllowedException' occurred in system.data.dll Additional information: Column 'REP_ID' does not allow nulls. Question is, How can I provide a proper row initialization when the grid creates a new row? That is, how can I detect the newly added row, and perform some initialization on the row's column values?

    - 3 windows, bring all to front Hi All, This should be pretty easy, and I'm sure there's a simple way to do it, but it's eluding me. The application has three windows open at all times. Needed functionality: a click on any of the three windows should bring the other two to the front as well so that they would all be above any other program windows. I've been messing with BringToFront and the Activated event but everything I do seems to lead into infinite loops. Hopefully one of you knows the 'right' way to handle this common problem.

    - Win2k3 SP1 affects IEExec ?? Has anyone encountered issues running NTD apps on 2003 SP1? I have an application that runs fine when run from IE on 2003 SP0. It also runs fine when run from the file system (i.e., double-click the exe) on 2003 SP1. For some reason, when we run the same app from IE on 2003 SP1 machines, we're getting System.TypeInitialization exceptions in IEExec.exe . When examined closer by building the app with debug symbols on the server, it appears that (at least in this case) the TypeInitializationException is being caused by an exception as a Web Proxy Class (for a web service) is being initialized. The Message is "The type initializer for "System.Xml.Serialization.Compiler" threw an exception. The stack trace begins: at System.Xml.Serialization.TempAssembly.GenerateAssembly(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, Evidence evidence, CompilerParameters parameters, Assembly assembly, Hashtable assemblies) at System.Xml.Serialization.TempAssembly..ctor(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, String location, Evidence evidence) at System.Xml.Serialization.XmlSerializer.FromMappings(XmlMapping[] mappings, Type type) at System.Web.Services.Protocols.SoapClientType..ctor(Type type) at System.Web.Services.Protocols.SoapHttpClientProtocol..ctor() Has anyone seen behavior like this?

    - why aren't changes in datasets recognized for bound controls? Hi, I've got a simple VB/Access app that binds text controls to various fields in a database table. Everything works fine, EXCEPT that when I call the Update method on the data adapter, nothing updates, because it thinks nothing has changed! If I make changes to the fields thru the bound edit boxes, and then check the "HasChanges" method on the dataset, it runs FALSE - even though the changes ARE reflected in the dataset's data! How do I fix this??? The Update calls do nothing even if I edit all the fields because the dataset won't recognized that anything has changed. The updates and everything work fine if I manually set new values into the fields; the update works and HasChanges returns true. ex.:dataset.tables(0).rows(0)("my field") = foo thanks!

    - How to track changes in a datagrid I'm developing a desktop app that displays several screens of of data in a two column fashion, the left column has the tiles and the right column has the input controls (textboxes, dropdowns, etc) for input. Typically the app is used to display preexisting data and the user would edit certain things. The data is saved on a network drive and can be edited by many users who have access to the drive (no concurrenct editing) so it needs to be able to track who changed what when. If a value is changed 10 times by 10 different user, it should be able to keep the history. I'm thinking maybe a DataGrid control is the best choice for displaying and accepting user input but not sure how it captures the change info. Could anyone point me in the right direction?

    - Cursor "stuck" In Databound Control/Caching? I am having a strange issue and cannot solve it. Basically, I have a form that edits information in a database. This form has many different controls that are bound to a business object. When I first load the form to edit the info everything works properly. The process of loading the object also loads the object into cache (Isolated storage using Enterprise Library 2.0 caching application block). If I load the form again and attempt to edit a field (say notes a textbox) my cursor gets "stuck" in the text box and I cannot click on any other control in the form. However I can close the form with the X in the upper right corner and the keys still function properly (Enter saves the object and Esc closes the form). I have looked the stack trace but it is giving me nothing. I have no idea where to begin. Has anyone seen something similar or have any ideas what it might be? Any ideas how I can go about getting some info to solve the problem? Tag: Context Menu for ActiveX control in VB.NET Tag: 89013

    - Custom Designer Hi, I'm writing a control called a validating submit button. Basically, you can tell it to validate a number of controls when the user hits this button. When they hit the button, it'll say, "You must enter yada yada..." and highlight the bad field. Ok, now that I've got that out of the way, I think this problem should be relatively easy. Basically, I created a special designer that was a form that had two lists, one of available controls, and one of controls it will validate, in order. It would then add these items an arraylist of the inherited button class. This seems to work fine! I can run my custom verb, have it open up and show all the items that are currently selected to be validated and all of that jazz, but it doesn't change the actual .vb file in the InitializeComponent sub of the test form. So basically, it can change all these values on the design-time copy of the actual control, but I can't figure out how to add code to the initialize component of the form that'll be using this control. I figure that this question ought to be rather easy, as being able to create a custom designer without being able to "save your changes," so to speak, is pretty useless, and probably a commonly asked question.

    - GUI from code Back in February I asked if anyone knew of a code-based presentation layer / layout manager. There are two: MyXAML (http://www.myxaml.com) lets you instantiate components such as forms and controls through markup rather than code. It uses an XML markup language (though not Longhorn's MSAvalon). MyXAML is open source. CoderForm (http://www.fivetuple.com) takes a different approach by keeping the UI spec within code, but wrapping the UI classes (Forms, controls etc) to make it easy to define the interface from code).

    - DragEventArgs and GetDataPresent with abstract base class Hello: I am trying to build a drag-and-drop operation with a control derived from my abstract base class. The control is either a PictureControl or a PictureGroupControl, both of which have PictureComponentControl as their superclass. When handling a DragOver event, I'd like to treat the dragged object as a PictureComponentControl without having to explicity test for whether the object is a PictureControl OR a PictureGroupControl, but GetData/GetFormats/GetDataPresent seem to only work with the subclass, not with the superclass. I've even tried explicitly casting the object when I begin the DoDragDrop() operation, but even then it doesn't seem to stick. Any advice for me? I know I could test for both subclasses explicitly, but that seems like bad OO -- then, in the future when I invent a SuperPictureControl, I'll have trouble. Is there a better way to do this, perhaps using Reflection or an Interface? Thank you, /m Tag: Context Menu for ActiveX control in VB.NET Tag: 88958

    - Validation of data in win forms 2.0, Insert I am developing an application that requires the user to add and or change data. The application will be coded in winforms using .net 2.0. I am struggling a bit to understand how to implement validation of the data. A simple example is a table the has Description and Remarkscolumn. The Description is a required field. It must be non blank. I have implemented a dataset for this table and have implemented validation in the OnColumnChanging event in the datasets partial class. I have wired this into an errorprovider component on the winform. THis works as I expected on an update. The validation logic successfully finds the blank column and stops the user from entering a blank value. An insert does not work as I expected. The OnColumnChanging event does not seem to get fired on an insert. Any help would be appreciated. Tag: Context Menu for ActiveX control in VB.NET Tag: 88955

Apart from a minor issue at the moment where the actual log isn't created and it uses the "Application" one, I always get the following: "For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp." added to the bottom of each of my "information" type event log entries. As you are aware there are the following types: Error FailureAudit Information SuccessAudit Warning Does anyone know of any way to either turn off that line from the log entry, or, add my own 'types' to the event log types so that I can use my own "RobsInformation" for example as a type that doesn't display that surpurflous link.... Any information would be really appreciated. I have other applications (obviously), installed on my PC, and things like Norton AV write to the event log with "information" type entries, but they dont have URL's back to MS. In an ideal scenario here I'd be able to add my own URL pointing to a web page that gives details of the error message (as MS do). Thanks in advance for any help.

I'm using ActiveX control in my VB.NET project. It pops up but execution doesn't stop on Click event handler if I set a break point there.
