• .NET Development Accessing USB Port using Visual Basic.NET

  Hi all, I am currently doing some programming task to access USB port via VB.NET SE. The program is supposed to control the device connected via USB and I have some problems in what class or namespace I ought to use. Can anyone help me with this problem Thank you very much.

• .NET Development Quick Start Sample MultipleSchemas

  I am developing a Validation Schema for a few large applications. We want to be able to share the portions of this schema that are appropriate between applications. We decided to do this by using multiple schemas. In my research I stumbled across the quick start example in: Microsoft Visual Studio 8\SDK\v2.0\QuickStart\howto\samples\xml\MultipleSchemas\cs\MultipleSchemas This sample uses two different schema files to completely define the type book. This looks like exactly what we need however the sample doesn't work properly. For example there is an entry in books.xml that is as follows: <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2"> <title>The Confidence Man</title> ...Show All

• Visual Basic Upgrade Wizard Fails at Form Parsing Step

  Hello. I am upgrading one exe project of a VB6 group and will have COM interop components. During the execution of the Upgrade Wizard, a run-time error "System Error &H80004002 (-2147467262). No such interface supported" occurs. The dialog caption contains the name of a UserControl. Once I accept the message the Upgrade Wizard completes. I am running VS2005 SP1. What can I look for as the cause of this message and what possible effect did it have on the upgrade Thank you. Hi Steuckra, If you can please send me a small project with the usercontrol that reproduces the problem I'll be glad to take a look. You can send it to JohnHart at Microsoft.com ...Show All

• Windows Forms Automate PDF reading

  Hi, I am trying to use the acrobat reader to read and view the pdf file. When I am using the acroPDF it works fine except it doesn't have the function of searching text (that opens the search panel and do the search). I have tryed objects like AcroExch.AVDoc but it can't create the type defenition of it and it said that a class doesn't registered. I checked it in registry. It doesn't exist there. Here the example of code: <code> // Create an Acrobat Application object Type AcrobatAppType; AcrobatAppType = Type.GetTypeFromProgID("AcroExch.App"); Acrobat.CAcroApp oAdobeApp = (Acrobat.CAcroApp)Activator.CreateInstance(AcrobatAppType); // Create an Acrobat Document object; Type AcrobatPDDocType; ...Show All

• Windows Forms mshtml not returning results

  I am working on creating a CCW, but am testing my code in a Visual Basic .NET 2005 with .NET 2.0 windows application. I am trying to get all of the href attributes from a web page. I have been looking around, and have found very helpful stuff that has gotten me to where I am, but now I am stuck. In my code I try to get the links from the links collection, and roll them out in a text box, but it is saying there are no links in the collection, but I know there is because if I use the webbrowser control it returns many of them (I can't use the webbrowser control in this circumstance though). Here is my code: [CODE] Imports mshtml Imports System.Runtime.InteropServices <ComVisible( True ), ComImport(), Guid( "7FD5 ...Show All

• Visual Basic suppress exception text in immediate window?

  This is not particularly a VB question as it is an IDE question. Is there a way to suppress the display of first chance exception text in the immediate window My app throws a plethora of expected errors as I'm building a database. I trap these errors and handle them and the code works fine. However, I have other debug output that is being lost in the flow of exceptions. Is it possible to tell the IDE not to display the first chance exception notification in the intermediate window I'll bet it's an attribute somewhere, eh Thanks! Sean Found the answer - google is your friend. Open the Output Window, right click, uncheck "Exception Messages". Voila! ...Show All

• SQL Server "Current day" MDX

  Hi, is there any "update" on how to do the "current day" as a set in MDX with SQL 2005 based on the actual system date If you don't want to base that on the system date is this still the "best practice" to introduce some "flags" in the time dimension to identifiy the actual day, last week, ...

• Visual Studio Team System Ignoring system tables and procedures

  Is there a way to not import system tables and procedures into a project I believe when the source database you are importing from has the option for system tables and procedures to not be viewed they don't import. Since we are trying to import from our production environment we don't have permissions to change these settings. Also going through and selecting all the system tables and procedures to be skipped is a pain, so maybe giving an option like Ctrl click to click mutiple objects to skip, or shift click to select most of a list, or just anything so you can skip multiple objects more easily. Actually they are created by the Database Diagraming tools in SSMS and Enterprise Manager, and since these ...Show All

• SQL Server Can't Route to another LOCAL Broker Instance

• SQL Server SQL Server Express won't install with default service name

  Anyone else had this problem I think I had a beta installed at some point. After a dozen attempts, I got SQL Server Express to install, but I had to change from the default service name (SQLExpress). When trying to configure the .NET samples that come with Visual Studio 2005, the ConfigSamples.exe does not recognize that I have SQL Server Express installed. I suspect this is due to my non-default service name. I have verifed that there is not a service installed (at least according the Services Admin Tool) that is named SQLExpress. I just dropped over $600 for a personal copy of 2005 Professional, and I would just like to view the samples. Someone take pity on my poor soul and help out. I promise to help you help me and show much ap ...Show All

• Windows Forms How to create an instance of System.Windows.Forms.AxHost.State ?

  I am writing an user control, it would add the ActiveX control by checking the installed version of Office Web Component SpreadSheet (currently there are OWC11, OWC10, OWC components). After checked the installed version of OWC, I create the instance of the axXXX library which generated by vs.net 2003 & add this instance to UserControl.Controls. If I do nothing more then it would be OK, but I wish to set the CSVData property of the instance after the constructor of the UserControl finished. I got an error said that OcxState of the OWC instance is valid. I noticed when I drag & drop the OWC control into the UserControl, the designer would generate the code such as : owc.OcxState = ((System.Windows.Forms.AxHost.State) ...Show All

• Visual C# How to read a binary file into String?

  Please note my binary here does not mean the 1s and 0s, but those unprintable characters. I tried to use File.ReadAllText() but found that the data has been changed. And if I use File.ReadAllBytes(), then I found that in order to convert Byte[] to String, I need to define an encoding. But the data is not a language text but actually some image data. What is the best way to convert a byte array of unprintable character to String Please help. I will grade your answer. Thanks Matthew Watson wrote: If it is not text, why do you need to convert it to a string Why not leave it as an array of bytes Good question. The reason is that I need to manipulate the content by adding some text in ...Show All

• Software Development for Windows Vista Taskbar Thumbnail API

  Our app currently does not display properly in the taskbar live thumbnail in build 5384.  It seems to not display any popup windows in the thumbnail.  Is there an API that allows us to construct our own thumbnail for this (or can we turn it off) Thanks. Is there any way to control the taskbar thumbnail I need my WPF app's thumbnail to be pretty much anything *but* the window content just before minimize. The live window content would be great. A static image of my choosing would also be OK. No thumbnail at all would even be acceptable. Alternatively -- and even preferably -- is there some event I could listen for to change my window content before the taskbar thumbnail "snapsho ...Show All
