• Windows Forms Validating data in a bound datatable

  I want to validate data for a datatable bound to a datagridview. To cancel an edit for bad data, from what I can tell from the MS docs, I can set the columnerror or throw an exception in the handler for the columnchanging (or rowchanging) event. I tried throwing an exception and that works fine when I do the edit programatically. Ie, try > add a row of bad data > catch exception. But where do I catch the exception when bad data is entered into the DGV The dataerror event of the DGV gets errors from ConstraintException, NoNullAllowedException, and ArgumentException - this works fine. Is this supposed to get the exception that I throw too I am throwing an ApplicationException. Is this right I can catch the exception right afte ...Show All

• Smart Device Development Tray icon with menu

  I'd like my application to just consist of a tray icon that shows a menu of actions when it is clicked. Preferably the icon would be at the top next to the volume, time, etc. but I could live with it at the bottom. I've seen this behavior in this Magic Button program: http://www.trancreative.com/mb.aspx So far I have been able to load an icon at the bottom, but I haven't had any success moving it to the top bar or producing a menu when clicked. If anyone can provide pointers on how to accomplish this, it would be greatly appreciated. ...Show All

• Visual Studio Express Editions how to use standard method for keyboaed input

  can u suggest me a standard method to input a character from keyboard with echo and without echo....like _getch() and _getche() functions. what i mean is these functions are supported by vc++ 2005 express edition but are non standard and hence the code and exe wont be portable. i know that in standard c++ there is no method for above problem .but i want to create functions which are standard and which i can include every time when i require keyboard input i.e i wanna make 2 functions equivalent of _getch() and _getche(). kindly help nobugz wrote: _getch() and _getche() are ISO C++ conformant.

• Windows Forms DataGridView Parent->Child while Filtering

  Im have 2 DataGridView's and have then attached in a parent-child manner using DataRelation and BindingSource. This part works well. In order to make my software more functional, I put a search function on the parent DataGridView. When I search, though, it breaks the connection that existed as parent-child, and the child no longer updates based on the row that the parent has selected. The problem lies in the way I am filtering my parent view, but I dont know any other way to do it or how to 're-attach' the parent-child relationship here is the code that breaks the connection and filters the parent view.... DataView filteredView = new DataView( dataSource.Tables["Customer"], "LastName='Richards'", "", Dat ...Show All

• Software Development for Windows Vista how to find the designer associated to an activity

  I have an activity and need to know, whether it is drawn below a given designer or above it. How can I get a reference to the designer, that is associated with an activity to get access to the Location information The designer class has an Activity attribute, but Activities do not have a Designer attribute. Perhaps a good suggestion for the next release You can't - but you should be able to from an ActivityDesigner - which is where you'd want to do anything like this anyway. IDesignerHost is a service you should be able to get from any IServiceProvider through GetService. ...Show All

• SQL Server How to dynamically set the ServerPassword

  I have an FTP Task where I have to set the server password at run-time. I have the ftp connection manager set up. What I normally do is configure the ftp server connection manager using a dtsConfig file but I can't do that in this case. I won't know the serverpassword until I get a parameter from the user. Thanks Brian.  Yes, I do want to do it in the package because  the package is being launched via dtexec from a generic web app that creates textboxes for the parameters.  I would like to keep the web app  generic and free of package-specific code.  I created a script task and I set the password by getting the ServerPassword property from the ConnectionManager's ...Show All

• Visual C# Firing events in child classes...

  Hopefully somebody can explain why .NET will not allow me to do this... I have a class, NonStationary, which has a member CurrentValue, and an associated event OnCurrentValueChanged. Now, I have two classes which inherit from NonStationary: Joint, and Shaft. Inside Joint and Shaft, there are times when, if the user hooked the event in the application, the event will be fired because he/she has set a min/max value above/below the currentvalue. The problem is, is that I cannot check to see if OnCurrentValueChanged has been hooked (if it's null), nor can I fire the event from within the Joint or Shaft class. The error I get is: "The event 'OnCurrentValueChange' can only appear on the left hand side of += or -= (except when used from wit ...Show All

• SQL Server restoring a db in SQL Server 2005

  Hello, I received a backup Sql Server file and I am trying to restore it. When trying to restore the backup using SQL Server 2000, I get the following message: "the backed-up database has on-disk structure version 611. The server supports version 539 and cannot restore or upgrade this database. RESTORE DATABASE is terminating abnormally." After doing some research online, I figured out that the backup I received must be from SQL Server 2005. Therefore, I installed SQL SErver 2005 on my laptop (so now I have both 2000 and 2005 on my laptop).. I tried to use the restore database option in SQL Server 2005 ( SQL Server Management Studio) to restore my backup, and I get the same error message (written again below) as I did ...Show All

Then upon pop-up dialog I want to be able to see the public value and update in the pop-up and later the update should be able to be seen in my main form.
