• Windows Forms Calling MsgBox inside a TabPage's Validating event

  I have a form that contains a tab control. I want to perform (multi-field) user input validation when the user changes tab. If the user input is invalid, I want to display a MsgBox. However, whenever I call MsgBox inside a tabpage's Validating event, this seems to affect the behavior of the comboboxes on that tab page. To see what I mean: 1. Create a new project 2. Create a form 3. On the form add a tabcontrol with 2 tab pages 4. On the first page add a combobox with a few items. 5. Handle the first tab page's Validating event this way: Private Sub TabPage1_Validating( ByVal sender As Object , ByVal e As System.Compon ...Show All

• Smart Device Development Serialport XON/XOFF Handshake State

  Hello all I found the following problem/speciallty in SerialPort I/O with XON/XOFF handshaking. When the SerielPort is opened and set to xonxoff handshaking it is ready to send files, so it is in xon state. When I send a file to the reciever and my device recieves an xoff after the transmition is complete it is then in xoff mode. After this I can't send anymore files because the port is blocked in xoff and my reciever won't send an xon to start. The other thing is I don't know wich state it's in. I have to close and reopen the port to get back into xon mode, then I can send the second file. Does anyone know if the serialport ...Show All

• .NET Development Datasets aren't finalized after leaving the scope

  Hi, we discovered a strange behaviour concerning garbage collection of datasets. Because our application needs a tremendous amount of memory and constantly allocates more and more of it we are counting the instances of our objects in memory. Thus we able to determinate if an object is finalized by the garbage collection. Basically most of our objects contain these code snippets in the "new" and "finalize" methods: Public Sub New ()     MyBase . New ()    TestClass.SharedCounter += 1       'Shared variable of integer End Sub Protected Overrides Sub Fina ...Show All

• Visual C# Sorting Algorithms

  Hi there, Does anybody know why the QuickSort algorithm (found at the end of the article at the below link) is substantially slower than the ArrayList.Sort() method http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnaa/html/getstart_vcsharp.asp I tried both out on about 420,000 strings (within which there were some duplicate strings) and the above algorithm took 9 seconds and the ArrayList.Sort method took just 1. Any ideas Thanks, James ArrayList.Sort() uses the same algorithm, so it's probably a matter of overhead: ArrayList.Sort() can work directly on the array (i.e. u ...Show All

• Visual Studio Team System TFS Source Control Bug

  If you check out a project for editing, add an object (form, control, class), then delete the object for any reason before checking project in, you will get an error that the file can't be found for the check-in process. I need a workaround for this.  How do I check in my changes without that file   The only solution I found was to undo all pending changes which deleted all of my code changes in the project, then check back out and re-do all my work.   Not good. There will be another CTP (Community Technology Preview) in the next month or so but it won't be a "tested release" so I wouldn't use it for production deve ...Show All

• .NET Development How to tell if a specific CultureInfo designates time with post meridiem or "military time?"

  Hello, I'm looking for a boolean somewhere which tells me whether a specific CultureInfo object requires the meridiem notation (AM/PM) or uses a 24 hour designation Should I check the DateTimeFormat.PMDesignator for null There should be a better way.... I hope. Thanks! Kevin So then, it would be something like this public static bool UsesMilitaryTime(DateTimeFormatInfo dateTimeInfo) { return string.IsNullOrEmpty(dateTimeInfo.AMDesignator) && string.IsNullOrEmpty(dateTimeInfo.PMDesignator); } Seems kind of hackish to me.

• Software Development for Windows Vista Patching software under UAP/LUA

  I'm not sure if this is the proper forum, so please let me know if there is a more appropriate place for me to ask these questions. We have a patching system that is written to handle patching all of our games.  It handles binary differencing, and also knows about our very specific file formats, and can work with products installed years ago, before Installer 3.0 was released.  According to this document ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/msi/setup/least_privileged_user_account__lua__patching.asp ), patching while in a Least Priviledge account requires installing using Installer 3.0 from removable me ...Show All
