• Visual C# Passwords

  Hello, I have a few questions relating to passwords. For starters, how do you make the password application so that it will recognise both the password and the username (ie. if the username is valid but the password isn't (or vice versa) how can you make it object until both are valid) My second (and final) question is: if the user wishes to change his/her password or username, how can he/she do it with out it reverting back to the old one next time he/she needs to enter it Thanks.

• SQL Server Problems using RSClientPrint

  We are using VB.NET 2005 to develop a WinForms application that uses SQL Server 2005 Reporting Services to produce reports. We want to print a large report programmatically without preview. RSClientPrint looked like a good solution but it produces an error when we try to use it. Details... I added Interop.RSClientPrintLib.dll Version 1.0.0.0 to my application and used the code sample I found at: http: / / msdn2. microsoft. com/ en- us/ library/ ms159195. aspx The call to print looks like: RSClientPrint.Print(" http: / / ourServer/ reportserver ", strReportPathParameters, "Report_name") This call generates an error message: "An error occured during printing.

• Visual Studio 2008 (Pre-release) consideration about XamlView

  Does anyone have tried the XamlView at http://www.codeplex.com/XamlView I have tried to use this tool to view my resource dll. The xaml content can be view almost as its original. Since I am developing a smartclient application, the dlls will be deployed to client machines. So how to avoid the design to be viewed directly Any suggestions Hi, Yong What you said is quite reasonable. But, I don't think there are commercial applications released without protection or obfuscation. What I am worrying is the xaml files almost remain what they are design. ...Show All

• .NET Development Is there any method to assign encoding in mailaddress?

  Hello. I have faced the problem about automatically sending email in my system. My website is allowed people type in chinese character and two of them are: 1. Seller Name 2. Seller Email Address After people type in all their information , a email will be sent for them for reference.

• Windows Forms controlling the focus

  Hi. Does anyone know how can I make a control work without recieving the focus The thing is that I'm trying to simulate a kyboard (on a UserControl) which is added to a form. Whenevet a key is clicked, I use the SendKeys.SendWait method to simulate a keystroke. In order to process the simulated keystroke, the recieving form should be in focus. To achieve this, I use the SetFocus API function with the handler of the recieving form. So far so good - it all works fine except for the slight occasional control bar flicker when changing the focus. So - is there a way to avoid all that focus transfer You'll need to give up on SendKeys if you want to avoid the focus problem. You could send the WM_KEYDOWN and WM_ ...Show All

• Software Development for Windows Vista Writing an ISO image to disc

  Hello everyone! Thanks to everyone who participated in the Optical Beta chat today! I'm trying to get a better, full-feature sample that we can put up on the forums, but for now here is a sample derived from our WinHEC slides that burn an ISO image to a disc.  The only missing piece is creating a stream over the ISO file.  I cannot get a piece of code that I can release for this in VBScript yet, although a good start is SHCreateStreamOnFile for C++ development.  Even though it does not work without this one function, this sample still shows the necessary steps to burn an ISO image.  Although this is officially unsupported code, I'd be glad to answer any questions about the IMAPIv2 functionality it exhibits... ...Show All

• SQL Server SQL 2005 backup to a different server

  I have a SQL 2005 database server. I need to create a database maintenance plan that backs up to a different server. Currently, I can see the C and D drives on my database server, but not any other drives - even the ones I am mapped to. In SQL 2000, I use to enter/type in the mapping, but when I enter the mapping in my database maintenance plan, the database backups are not working. I am not getting any error message. When I execute the maintenance plan, it just checks off the steps and ends with success. It only takes about a couple of seconds for the plan to finish with the success notice. I have added sqlserviceacct to my other server's administrators group, and it has full permissions on the other server also. How would ...Show All
