• SQL Server indexes question

  Assume we have a sales table, which contains a OrderID(char(8)) and a OrderDate(smalldatetime) field. Each day, hundreds of thousands of records needs to be inserted into this table. We need a daily sales report, and the OrderID is not necessarilly sequentially entered (every data operator has a range of OrderID, so for each data operator, it is sequential, but globally, it is not). So, I would like to create a clustered index on OrderDate, and the Primary Key is on OrderID. I think it is good for generating the daily sales report. However, when an order is entered, we need to quickly check if the OrderID already exits, because the unique index on OrderID is built on the clustered index (on OrderDate), which means the Database Engine will ...Show All

• Windows Forms Playing multiple sounds simultaneously with SoundPlayer

  Hi All, I'm trying to get the SoundPlayer to play two wav files at the same time. The documentation says is should play asynchronously but when I try, it seems to end the play of the first SoundPlayer as soon as the second one starts to play. I tried doing it with Theading as well but got the same result. Any suggestions would be appreciated. Thanks in advance for sharing your expertise. ~John Here is a snip of program with just pertinent code. namespace Test4 { public partial class Form1 : Form { SoundPlayer [] aSoundPlayer ; public Form1() { InitializeComponent(); aSoundPlayer = new SoundPlayer [2]; aSoundPlayer[0] = new SoundPlayer (); aSoundPlayer[1] = new ...Show All

• Visual C++ Encryption and strings problem

  In my code here String ^tmp = ""; if ( !split[x]->Contains("_") ) } tmp = String::Concat(tmp, String::Concat(objCrypto->Decrypt(split[x], 0), "\n\n")); } split is an array of strings and in this array there is encrypted data. The first string that needs decrypted is found it is returned decrypted from objCrypto and added to the tmp string as it should. However when the second encrypted element is found it is returned unecrypted from objCrypto but is not being concatenated on the tmp string. What am I doing wrong. This is a question concerning a .NET security class, not the C++ language. I would ask your question here instead: http://forums.microsoft.com/MSDN/Show ...Show All

• Visual Studio Tools for Office Add Worksheet From template

  I am trying to add a worksheet from a template, the documentation says this, If you are inserting a sheet based on an existing template, specify the path to the template, if I do that it throws an exception, I am using C#, any suggestions Actually please disregard the previous comment. Found that Workbook.Add can accept path to the template workbook as its last parameter. Not sure if I can provide many insights. I would start troubleshooting by first trying to add a very simple template, then try adding more features to the template and see when it starts to break. You can also use VBE's immediate window to speed up the troubleshooting - at least you won't need to recompile your code every time. Hope ...Show All

• Architecture Using Persistence Objects: What are the advantages?

  I pose this question for anyone who has experience in both using and not using data persistence objects in their domain design (i'm talking about mid to large size applications) What are advantages of using persistence objects in conjunction with domain objects to move data to and from the data layer (database, files, etc) To me it seems like having the data access ORM code in the actual domain object gives that object total control and flexibility over handling/validating its own data with no performance overhead. All domain specific logic is in one place which makes maintenance easier if the busines rules need to be changed. I would be very interested if anyone has a good, real-life example or explanation of why using Persistence O ...Show All
