• Visual C# Use of escape sequences

  I want to know when I have to use the \r and when \n escape sequence. I am dealing with the code in which the \r\n is being used. My understanding \r is carriage return and \n newline character. The \r or carriage return takes the pointer to the start of the line and newline starts at next line. What is the advantage of using them both together thats what I am trying to figure out. The link I am giving below has the definitions of the various escape sequences and there are some articles in wikipidea.com about these too. http://msdn.microsoft.com/library/default.asp url=/library/en-us/csspec/html/vclrfcsharpspec_2_4_4_4.asp ...Show All

• Visual Studio Express Editions problems installing Visual Studio C++ Express

  Hello, I couldn't install using the Installation Wizard, I got a message about it not being able to download b/c it couldn't install MS.NET Framework 2.0. (I did click on a link to separately install this component, but the Wizard still wouldn't work.) Then I went to the manual install link. I successfully downloaded and installed isobuster to recognize IMG files. Then I went to the folder on my hard drive where I put the C++ installation files. I couldn't find a file that is named setup.exe, although there are several files that have setup in their names. The one called Setup (Suite Integration Toolkit Executable) didn't open.

• Visual Studio 2008 (Pre-release) ANN: A simple Portal User Interface

  Inspired by live.com I have thought about creating a similar UI: http://www.valil.com/portaluitest/portaluitest.xbap Try to move the panels or expand/collapse them. It seems that the animations are using software rendering so if the animations are running too slow, try to collapse/close some of the panels. Right know the content is static and there is no posibility to add other panels. There seems to be a problem with the horoscopes layout, try to resize the browser window. Enjoy! ...Show All

• .NET Development Sockets WaitForAny

  I'm using Aync socket call BeginReceive, I'm worried that this is using the threadPool and having 50 or more open sockets would cause the threadpool to be depleted, thus use a single thread for posting events back to the receive,transmit,connect tasks using select, but I want the thread to gracefully be aborted, is it possible to use select to wait for a event, ie ManualRest, I'm trying to port the C++ code to C# that can map Socket handles to Events then use WaitForMultipleEvents for exit event and socket events... there is no one to one correspondence between an Async call and a thread pool thread. It is e ...Show All

• Visual Studio Tools for Office Document protection

  Hi, I have problems with the Word document protection mechanism inside VSTO Beta 2. When I open a Word document inside the Visual Studio IDE and I try to apply document protection, the button "Yes, Start Enforcing Protection" is always grayed out. Furthermore, when I programmatically protect the document (Document.Protect) and allow specific sections to be edited (Range.Editors.Add), those sections have a strange behaviour.  They are not fully editable: I can write inside them but I can't delete the text inside them. Has anyone had similar problems Is there any fix for them Thanks! Mike ...Show All

• .NET Development FtpWebRequest method=Create Directory problem with "#" in the directory name.

  When i try to create a directory on a server with FTPWEBREQUEST with a # character in the directory name it only creates the directory name up until the # character. For example if i try to create the directory "C# Express" only "C" gets created on the server. I if send "C++ Express" it creates "C++ Express" on the server. I'm going to check into other characters that are valid for a directory name but don't get created with FTPWEBREQUEST. lushdog I'll try that but my directory names are coming in through a dialog box so i'll have to rewrite some code to f ...Show All

• SQL Server Changes in SQL2005 syscolumns table

  It seems MS changed the way syscolumns table works.  It appears this is no longer a table, but probably a systemview.  Problem is, it looks like the autoval column is no longer working.  I was using this to determine whether a column was an auto incrementing identity field.  How should I go about determining a column's auto increment values Thanx, Or this: SELECT t.table_name ,c.column_name ,c.* FROM information_schema.columns c INNER JOIN information_schema.tables t ON ( t.Table_name = c.Table_name AND t.Table_Type = 'Base Table' ...Show All

• Visual Basic HotFix did not solve my problem

  I too installed the hotfix and I am using edit and continue successfully and I do not get the notify Microsoft message over and over, but alas, the problem that has plagued us most is still in place. When using the Visual Studio IDE (using VB), if we make the slightest change to a winform and then run the app, after returning to the app in design mode, we consistently get a big red x on our design surface that locks us out of the form. Accompanying the big red X are a number of different messages that change and are not consistent. The only solution for us is to rebuild the application (right then) exit Visual Studio and come back in. ...Show All

• SQL Server FailParentOnFailure not working?

  I have a script task inside a sequence container with the FailParentOnFailure = 'false' and the FailPackageOnFailure = 'false'.  However, when I deliberately fail the task ("Dts.TaskResult = Dts.Results.Failure") the sequence container and the package still report failure.  Any thoughts Thanks An error doesn't equate to failure. Establishing if a task failed precedes any action the package takes _when_ the task fails. As the package writer, it's up to you to decide how many errors constitute failure. The default is one, but you may decide that, for example, you want to have a task retry an ope ...Show All

• Visual Studio Full MSDN local install for VS 2005 incomplete

  I have recently installed Visual Studio 2005 and am having trouble with the local Help functionality. Local help is missing a host of very basic keywords and functions such as fprintf, #include, #define etc. (although other things are available, such as the STRCONV() function). I can click on a keyword, press F1 and be directed to online help, which always has the information I need. But if I search for the same item in the Index pane of local Help, I get a No Topics for Index Entry error and am told to click on one of the child elements. This occurs even when there are no child elements to click on. And I am not directed to online hel ...Show All

• .NET Development SQL Server roles & ASP.NET 2.0 Forms Authentication Roles

  Apologies if my post does not fit into this forum. If not please let me know which forum would be best. Is it possible for a web user who has been successfully authenticated with forms authentication to be authorised to use a SQL Server 2000 role depending on a particular ASP.NET 2.0 role that they have been authorised to use I understand that that I can assign a SQL Server 2000 role to the ASPNET or NETWORK SERVICE account but this will grant access to anonymous web users to the database role. I can ensure that I only call stored procedures which access sensitive data in web pages that are in restricted by ASP.NET roles. However ...Show All
