• Software Development for Windows Vista Workflow Versioning on an automated build server

  I'm attempting to automate a build, and I'm having an issue with our Windows Workflow custom activities. I must confess I know little about Windows Workflow and I'm seeking some advice from others on how to approach this. It appears that an automated version incrementing task breaks the WF compile on the custom Activities with errors such as: C:\projects\Workflows\Workflow.xoml : error WF278: Activity 'SendException' validation failed: Property 'InterfaceType' is not set. C:\projects\Workflows\Workflow.xoml(4,5) : error 347: Could not deserialize object. The type 'XXX' could not be resolved. After I did a find/replace on the 'Version=1.0.0.0' tag within the XOML file with the newly incremented "Version=1.0.0.1" tag, ...Show All

• Visual Basic Calling Arrays into Function/Subroutine calculations

  Hi, the topic might sounds confusing but anyway, I'll explain in details with an example Says I have a function call "totalVal" which accomulates all the values inside a matrix according to the dimension values of x and y. --------------------- Public Function totalVal ( byval Arr_x# ( , ), byval x%, byval y%) as double Dim Val as double, i , j as integer Val = 0 for i = 0 to x for j = 0 to y Val = Val + Arr_x(i, j) next j next i Return Val End function --------------------- Calling the function in some other code. --------------------- Val = totalVal ( ArrayX (, ), 4 , 4) --------------------- For some reason VB doesn't allow me to input an implicited array like ArrayX(, ) into the function. Does anyone know how to get this to w ...Show All

• Visual Studio Express Editions .net redistributable

  I have written a program in VC# Express, and it's purpose is to be installed on school computers where downloading and installing privelages are limited. Using VC# Express, is there away I can include the entire .net framework in the package so that it doesn't have to connect to the internet If not, can I do so in Visual Studio .NET 2003 Professional To run the .NET programs, the computer must have .NET Framework installed.

• Windows Forms Moving back and forth between records in a DataView

  Hi, Here is the scenario I currently have: I have a DataGridView bound to a DataView containing a number of records (form1). When a user double clicks on a row it brings up a form (form2) containing details on the selected row. I have this part working without a problem. On form2 there are two buttons enabling the user to move back and forth through the records displayed in the DataGridView. I want to know if it is possible to move back and forth through the records in a DataView and if so how. I am using Visual Studio 2005 and C#. Thanks Any chance of a code example Thanks ...Show All

• Visual Basic LEFT string function

  This is how you would use the LEFT function in VB6 ... str1=LEFT("This is a typical string",4) Can you still use the LEFT string function in Visual Basic 2005 I can't seem to get it to work. Hi, Terry,   MS.VB is essentially already imported, as is the System.Windows.Forms namespace.  Consequently, adding an import won't help you here -- they're just two imported namespaces which happen to have conflicting members (as might happen with any arbitrary imported namespaces).  However, you can set up an alias like: Imports VB = Microsoft.VisualBasic and then the call would be VB.Left, which is a lot easier to type.  (You can substitute whatever you like for "VB" ...Show All

• Visual C# Printing to a dot matrix printer without feeding an entire page

  I need to be able to print a number of lines to a dot matrix printer, but not have a full page length feed through the printer when I send the PrintDocument for printing. Thus far, printing in the traditional .NET fashion spools an entire page out. There must be a way to do this, but I can't find it. Ideas >> probably using the SerialPort classes in .NET 2.0 to have direct access to the printer Note, however, that most printers use (traditionally) the Parellel port or (more recently) the USB port. I haven't seen a printer attach to a serial port in 20 years. ...Show All

• Visual Studio HTML Help from .HLP Projects

  I have a series of projects to convert from the older .hlp style to .chm. The HTML Help workshop has a convert option, but it fails most of the time for graphics. I use HTML Workshop to convert the .hpj file to corresponding .hhp relates files. All seems to go fine, but virtually all the graphics images in the original .rtf files are missing from the fiinal .chm result. In some cases, it works fine, but that's the minority of cases. Any ideas Ed Yes, unfortunately there is not a convenient one-to-one conversion mechanism in the basic tools we provide. If you use a tool like RoboHelp, you may be able to more successfully import your .hlp source and convert it to an HTML Help project. ...Show All

• Software Development for Windows Vista Transactions - ensuring consistency between WF and MSMQ

  Apologies in advance this might be quite a complex one! I should say at the outset that I don't want someone to write my solution for me, just am trying to understand a bit more about how to achieve transactionality in WF. I'm currently trying to pilot an STP engine using Workflow Foundation to prove its suitability. Everything in the engine is driven using transactional MSMQ queues. It's essential that no information is lost, and that the workflows remain in a consistent state with the contents of the queue. These are the scenarios I'm trying to tackle at the moment: 1. A message arrives on a queue and triggers the creation of a new workflow. 2. A message arrives on a queue and is passed into a waiting workflow. 3. A workflow ...Show All

• Visual Studio Express Editions Issues to watch out btw 1.1 and 2.0

  I'm not very sure where to post this qns and i'm using C# so i think this would be the approriate forum to post. I am told to develop some applications using C# in .Net 1.1. However with the usage of express edition, i would be require to use 2.0. I would like to know the possibility of compactability issues if my development is done in 2.0 and deployment over 1.1 framework Appreciate any help.

• Game Technologies: DirectX, XNA, XACT, etc. Vista allows What versions of DirectX?

  (split from http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1221168  to make a new question) It is interesting that you say that because I am testing a VB6 app that was working fine on XP and below but now fails on Vista when it tries to create a DirectX8 object, specifically Set oDX = new DirectX8 throws Error 429, ActiveX failed to create component. Running in XP SP2 compatibility mode does not work either. I would be really grateful if anyone has any ideas on this.  I also tried running the latest DX9 redistributable because I heard that was providing backward compatibility, but to no avail. Thanks. After some research I've come to the conclusion that this file sh ...Show All

• .NET Development Derived types and System.Collection.Generic.Dictionary?

  Hi, I have a Dictionary in one of my classes: private Dictionary<string, RobotPart> _parts = new Dictionary<string, RobotPart>(); RobotPart has many derived Classes (Rod, Joint, Body, etc.) . I have a method called GetFlatPartList that flattens out a treelike structure of RobotPart objects, for easy iteration through the child objects. Hopefully, once I hit "post" my tabs will be kept for the following method: EDIT: I took this method out, and placed it in the following post for readability Now, my problem is that my program will crash, giving me an invalid cast exception when I am trying to search (using a for each statement) for any Type other that RobotPart, even though they (Joint, Rod, Body, etc.) are ...Show All

• Visual C# Why Won't My App Run on Windows 2003 Server?

  I am taking my first stab at writing an application in C#. My App is designed to watch a folder and report any created deleted or modified files. I created a simple form where changes are wrtiiten to a textbox, and concequently to a log file. I used the FileSystemWatcher Object, and wrtie to the text box and log file on the change events. This application runs fine on my XP machine, but fails to even launch on my 2003 server. I tried just a normal form on my 2003 server and it ran fine. Anything that could point me in the right direction would be great.
