• SQL Server NUMERIC or INTEGER ?

  Hi, Is there any difference between NUMERIC and INTEGER datatype I am currently migrating my application from oracle to sqlserver hence i need to know the best equivalent: Oracle var_int int(38); SQLServer: @var_int numeric(38) or @var_integer integer Please let me know the best equivalent --Srik Use integer in SQL Server for Oracle int. NUMBER is close to NUMERIC. Numeric implementation between Oracle and SQL Server is also slightly different. It has to do with storage and how we calculate precision/scale of resulting expression. It is best to understand those rules before using numeric other ...Show All

• Visual Studio Team System Warning about obsolete SuppressMessage attributes

  Would it be possible to have code analysis warn about obsolete SuppressMessage attributes in the code it checks When changing the code of a metod, a SuppressMessage attribute may become obsolete. so over time, your code can become 'littered' wth obsolete SuppressMessage attributes. It would be nice if code analysis could flag these attributes as being obsolete. It looks as if this should not be too hard. Code analysis has to search for attributes anyway to suppress messages during analysis. So a check if an attribute has really been used to suppress a message does not seem that hard.

• Windows Forms BindingNavigator & Data Binding Problem

  When I use BindingNavigator to add new record, I has a problem: I want to save time for input informations, so I set default value for some controls which has data bindings, but it's not working. for example, I always set DateTimePicker's value to System.DateTime.Now, set CheckBox's Checked to False. If I don't change the default value manually, when I try to save the new record, it'll said the value is null. When I use DateTimePicker, I must select a different value with the default one, otherwise it'll said the value is null. What should I do to fix this Hi! You can add ColumnChanging event for the ...Show All

• Visual C# Counting bytes passed in streams written to by StreamWriter.

  Hi, Is there a stream implementation or ICryptoTransform implementation similar to the md5 which simply counts bytes rather than calculates a hash. I am writing text to an encrypted file and need to know the md5 and size of the raw unencrypted byte data. I've seen code for calculating md5 of a stream, but need one which simply counts bytes. Something like this // File Stream FileStream fileStream = this.fileInfo.Open(FileMode.CreateNew, FileAccess.Write, FileShare.None);' // Encrypter wraps File Stream CryptoStream cryptoStream = encrypter.BuildEncodingStream(fileStream); // Md5 wraps Encryption CrytpStream md5Stream = = ne ...Show All

• .NET Development .NET UI Application Crash

  Hi, We have a vb.NET client UI application which calls a number of web services. The application is intermittantly crashing completely without any evidence of an exception etc. The application is single threaded for the most part, the only area that deviates is a class managing serial port comms via win32 calls. (we do not use p invoke..) I understand the most likely cause for an unexpected termination of this nature is threading - more specifically that referencing UI elements unsafely... I can say after a very large code review that this does not take place. Can anyone provide any advice on what might be the cause or where else we might lo ...Show All

• Visual Studio ".exclude" files in web project are themselves getting added to Source Control

  Hi, I have read various posts about how it's not possible to exclude files from a Web project in the way we could with VS 2003. A bit of a pain in some circumstances, but fair enough. However, the exception to this rule is the dlls in the bin folder, because VS generates associated " .refresh " and " .exclude " files for these files, which in turn should cause them to be excluded. (Happy to be corrected if I'm wrong on this point) However, after getting in a bit of a tangle with VSS bindings, which I have hopefully restored correctly, all the " .exclude " and " .refresh " files in the bin folder are marked in the pending checkins ...Show All

• Windows Forms Is it possible to create a desktop icon using ClickOnce

  I found only one article about creating desktop icons, but that article (MSDN) ruled out creating desktop icons. Is this possible with ClickOnce or not I know windows installer will, but we have a Smart Client and want to provide a way to create a shortcut to the app on the desktop so people could get to it quickly. Any suggestions Thanks     It is not a feature of the deployment.  In fact, it is not obvious that a ClickOnce application installs a shortcut in the start menu.  A user would really never know at install time.  I would recommend having your program ...Show All
