• Visual C# bulk email...

  Hi all, Could some one point me to some code/article to do this or pseudo it for me in bullet points: I want to write a C# service that monitors a folder for changes in a text file that gets updated with email addresses & then send them off. To watch the folder I use System.IO.FileSystemWatcher ... but how do I bundle all the emails that were added to the file to get sent off using System.Net.Mail ... that's the part of the functionality that I'm missing at the moment Add them to an array! TIA String[] Emails = new String[] { "someemailaddie@hotmail.com", "someem ...Show All

• SQL Server does "with (nolock)" absolutely guarantee no locks are taken?

  I need to run a few short-running queries against a production system. I need to be absolutely certain that SS doesn't take out any locks on the table as a result. Does "with (nolock)" absolutely guarantee this I've read BOL on the topic and I understand isolation level read-uncommitted. But I want to validate that there's not any undocumented behavior in SS that might violate the documentation (which clearly states that no shared locks are issued). Thanks! You're talking two different things. with (nolock) is a HINT. That means there is a possibility that SS will override it. SET TRANSACTION ISOLATION LEVEL ...Show All

• Windows Forms CallBack in GridView

  Hello: I am in the process of extending GridView and adding some functionalities. For example, I added a single row click to postback and handle the event. I would like now to be able to do a CallBack instead of PostBack. Do you know if there is a whitepaper on how that CallBack functionality is added to the Grid currently through sorting and paging I believe it is better to follow the same technique used. I have been trying for some time, im getting all the needed methods and functions, and I have added for example: Grid1.EditIndex = e.GridViewRow.RowIndex; inside the handler of the sinlge click which is being fired upon a ...Show All

• Visual Studio Keyboard event capturing

  Hi, I am currently developing an add-in for debugging LUA (scripting language) code from within the visual studio environment. However, i cannot seem to find any way to capture keyboard and mouse events, can someone please tell me how to do this because i need to provide the default F10 key for stepping through the LUA code within the VS environment.

Can i use the default -> indicator for my own usage, if yes then can someone please tell me how and what ...Show All

• Windows Forms strange casting error with userdefined control

  In VS2005 beta2 we have made a Usercontrol which we are trying to place on a form from the toolbox. The problem is that we keep getting the following quite bizarre errormessage: System.InvalidCastException: Unable to cast object of type '<name of webservice>.<name of webservice class>.<dataset type>' to type '<name of webservice>.<name of webservice class>.<dataset type>'. So it says that it cannot convert from a type to the same type! Has anybode else experienced this kind of behaviour And found a solution I think there may be something wrong with the whole solution, because when I made a test ...Show All

• Visual Studio VS 2005 Beta 2 - "Beta period Expired"

  I am trying to install the second beta of Visual Studio 2005 from the MSDN discs ordered from MS.  After following the instructions for uninstalling VS.2005 Beta 1, I sucessfully completed the install of beta 2. However, when running Visual Studio 2005 beta 2, I get the error message "The beta period has now expired". Does anyone know what I have done wrong in the uninstall process of Beta 1 or how to get beta 2 to recognise this is a new beta Thanks Do you have a stack dump or an error message when Beta 2 crashes If you do, I can get the right folks to take a look. And there won't be a Beta 3 :) ...Show All

• Visual Studio LaunchWizard convert project id?

  I'm using DTE.Solution.Open("foo .sln" ) to open a solution, which raises an exception that the project needs to be converted to the latest version (it does). So I need to use DTE.LaunchWizard() to convert it before opening. But how do I find the guid of a given wizard   The GUID does not point to a specific wizard to run, rather it points to the context in how the wizard should be run, such as add a new project, a new project item, or your own type. There is no automated way of converting a project as per design. There can be problems in automatically converting to new versions, so we spe ...Show All

• Visual Studio VSS 6.0 - Error Reading from file.

  Hello All, I had configured VSS6.0 on my PC to hold all .c programs and some important project documents. Recently, my PC had some problems and XP Prof version was reinstalled on the C drive. The VSS folder resides on the E drive. So, I reinstalled VSS 6.0 on the C drive and connected to the VSS folder. Now I face a problem. It so happens that the contents of some of the folders are not visible at all and when I do a right click on the folder, it gives a message abt me not having sufficient permissions to access the folder. So, I login as administrator and try to set the permissions for myself thru the admin login. But it gives a message, ...Show All

• SQL Server FTS indexable table column

  Hi, how can I programatically identify if table columns are eligible to include in a FTS catalog index I can do this: SELECT COLUMNPROPERTY (object_id('Person.Address') , 'AddressID', 'IsIndexable' ) but what I'd like to do is: SELECT COLUMNPROPERTY (object_id('Person.Address') , 'AddressID', 'IsFullTextIndexable' ) but that property doesn't exist. The best I got sofar is to compare data types with what the documentation says, something like this: ... if (tc.Text == "char" || tc.Text == "varchar" || tc.Text == "nvarchar" || tc.Text == "varbinary(max)" || tc.Text == &qu ...Show All

• Visual Studio Team System Web tests resulting in Internal Server error due to Invalid ViewState

  I am seeing an odd problem when testing our web site.  I have no problems navigating through our website manually from a web browser and experience no problems when creating a web test that navigates through our web site. But, when I run the web test I created, then I keep getting an "Internal Server Error" on the first server page transfer.  When I look at our server logs it indicates that the problem is caused by an invalid ViewState. But, this problem only occurs when playing back (running) one of my web tests.  The ViewState appears to be formatted correctly (it can be parsed) but the error message gives no further indic ...Show All

• Visual Basic "hello world" won't run

  I am a newbie who just downloaded visual web developer 2005 express on my xp home system.  It installed without errors as far as I can tell.  Is express really stripped-down, and they don't tell you what is missing Like this "hello world" program example:  I can't paste the example page here, Right-click WON'T LET ME! Anyway, the page says "create visual basic console application project".  The closest I could find was a "create text template"  So I pasted the example code on that.  Then it says choose the appropriate "build command".  The choices I get are "build selection" or "build solution".  ...Show All

• Visual Studio Express Editions system lock of referenced assemblies

  hi, i have split up my program into 3 assemblies and the main. the sources are on the drive "P" and the output on drive "C". i got more then just "debug" and "release" configs, so what i got is a folder on "P" which holds the assemblies, which are then referenced by the main.  that way, no matter what config i got, the references will always be ok. in the postbuild event of the assemblies, i copy the DLL from "C" to "P". in VS2003 that worked perfectly, but now it works about 2 times and then i get an error from the postbild event script, because it can not copy the file. it apparently is used by another process ...Show All
