• Visual Basic Searching Arrays

  Can anyone help me with searching arrrays I have created a structure as follows: Public Structure PNSN_Struct Public TempPN As String Public TempSN As String End Structure My databse has a Partnumber table and a SerialNumber table, the SN Table has two fields PN and SN. My input form allows users to enter Serial Numbers for those parts that are serialized. So, as the user opts to add a new part to the dB I allow them to enter SN's into a listbox before I write the data out to the dB. As they try to enter a SN I want to ensure that they aren't trying to add a duplicate If not I add it to an Array. as they press the Add SN button, before it adds it to the List Box I call a duplicate_SN p ...Show All

• SQL Server Some strange behavior with parallelism

  Hi, In my package I have a source, a script component to make some changes to that and a destination. To speed up the process, within a data flow, I have created 6 copies of the above components and running them in parallel. Each source takes different set of data. I have divided the data using the record no such that, each set will read 1million records. Now, my question is, though each pipleline is supposed to process exactly 1million records, they are not running at the same speed. For example, 1 pipeline completes processing all 1million records whereas another pipeline processed only 250000 records in that time. I don't see any reason for why one should run slow while another is running fast considering that both are doing the s ...Show All

• Smart Device Development Secure password storage

  Hi, I'm making a business PDA application which gets and sends data from and to an Axapta database. For this i'm using SqlCE3.0 The problem I have now is that I have quite some bits that are sensetive information, namely the username/pass of the IIS folder where the SqlCE dll resides and the username/pass of the Axapta database. if possible i'd like to store the passwords in a secure storage on the device, does this possibility exist and if not, is it safe to store the key to decrypt/encrypt a password in code (I assume not, but where else if no secure storage exists) Thanks in advance, Ben. as this would have to be done everytime a sync or transaction is made this is not really feas ...Show All

• Windows Search Technologies Internet Explorer Tab settings not respected

• Visual C# How to use the controls from another form in form I working in.

  I have problem, I was using the Visal Basic, and now have to migrate to the C#. Its not a problem. But in first steps with C# I have found a few diferences from VB. One I cant solve. For example in Form1 I have a TextBox1 and a Button1. I enter in TextBox1 "sviec", and click the Button1. Then opens the Form2 with Label1 on it and label says "sviec". In VB the Form2 code looks like this: Public Class Form2 Private Sub Form1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load Me .Label1.Text = Form1.TextBox1.Text End Sub End Class So how I can translate this Me .Label1.Text = Form1.TextBox1.Text from VB to C# Thank You! ...Show All

• Software Development for Windows Vista Reusage of Rules Engine Components

  Hi! I've tried to reuse some components of the wwf rules engine. The goal was to validate expressions which are edited in an expression editor. But the rules engine only offers the ability to edit and validate conditional expressions (return type bool). All the classes are defined internal, so it is not possible to extend the classes. Does somebody now an option to validate more general expressions, or have I to refactor the rules engine and build my own solution Andreas ...Show All

• Visual Studio Team System Changing path of New TFS Project

  When I create a new TFS Project it stores it in the default location in sharepoint of http://servername/sites/<project name> I'd like to modify this so new projects are saved in http://servername/projects/<project name> How can I accomplish this Hi Randy, It is possible to do what you want provided that you don't currently have any sites at http://servername/sites that you care about accessing from TFS. The change you would have to make is a global change, it affects all existing projects, so all existing projects would begin looking for their associated sites at http://servername/projects . You could probably move these sites, though. TFS looks in the registration entries f ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SpriteBatch.Draw(..., float layerDepth) No Longer Works For Me

  I guess that the deprecated BeginScene() used to automatically changed some device states in order to make it possible for layerDepth to work. But since that function is gone in Beta 2, I no longer know how to automatically depth order my textures. Is there a set of device states I need to be in to get this automatic sorting If not, I'll just write my own sorting code. Thanks! bryanedds wrote: SpriteSortMode.Textures doesn't seem to work either. I'm currently impl'g my own sort algorithm. Really If you have a repro app that demonstrates this problem, please file a bug over on the connect site and attach your test code so we can take a look at it. ...Show All

• Architecture SOA - Transaction/compensation/cordination

  I have a challange. I have multiple services that are located on different server setups. They are build stateless N-tier architectures based on single call remoting. The services do not support the flow of transactions. This would also couple the services an go against the very idea of service orientation. But ..nevertheless, one needs to perform business operations that span multiple services. How do I best support this. Should I have the programmers do custom compensation code very time (clean-up) and accept that if something crashes the data is inconsistant or should I try to find/implement some kind of common cordination What are my choices Thank you Roger ...Show All

• Visual Studio Express Editions clicking a picturebox

  I have about 200 little pictureboxes that start simply white. When they are clicked they turn black. I'm using picture boxes because they are the only thing that can get as small as I need them. I'm hoping for a way that I don't need to re-write the code that many times. I've tried using Private Sub PictureBox1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click Me .BackColor = Color.Black End Sub But that changes all the picture boxes and textboxes and forms backcolor to black. I'm hoping there is some simple solution that I'm missing. Thanks for any insight. your code snippet is showing that you are setting the back color of the FO ...Show All

• Visual Studio Code references on the scrollbar?

  Hello, I'm used to using Eclipse IDE and one of the features I like is that when you left click any variable, all occurences of that variable in the code are highlighted on the scroll bar with little markers. You can click any of these markers to jump to that part of the code. It seems like the scrollbar doesn't have anything like this in VS as it is a standard scroll bar. There is a coloured line on the left with green and yellow but I don't know what that means. Is there any functionality to provide quick linkages between variable references in VS Do I have to right click and ask for the list That isn't very quick at all and is rather clumsy. Is there any extension that can add this functionality Thanks, Christopher ...Show All
