• Visual Studio 2008 (Pre-release) Faults, Exceptions, DataContracts - Oh My!

  Hi all, I'm just starting on WCF and have run into a number of interesting problems to do with the whole exception/fault concept. Basically, I've got a service which has the following operation defined: [System.ServiceModel.OperationContract] [System.ServiceModel.FaultContract(typeof(MyCustomException))] void throwsException(); MyCustomException is a custom exception class which is marked with the DataContract attribute (and has some custom fields with DataMember attributes). I then throw the exception as follows: throw new FaultException<MyCustomException>(new MyCustomException(...)); On the client side, I get a CommunicationException with the text "An error occured while receiving the HTTP respon ...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

• .NET Development COM interop to unmanaged OO COBOL component returns 0x8002003

  I am receiving 0x8002003 COM exception when I try to access a public property in an unmanaged COM component written in OO COBOL (Fujitsu NetCOBOL - not their DotNET product. NetCOBOL is a full OO implementation and creates COM components that function correctly. I have dropped them on ASP pages as well as used them on the Windows desktop) The component has a property defined as 8192 bytes (for compatibility with COM BString). I need to set this property, invoke a method called "FIB" (Fill in the blanks), then access the property to see what happened. I'm using C# Express so I don't have the SDK tools like TLBIMP.exe. Fortunately, I don't seem to need them as the IDE has generated an interop Assembly for me and when I loo ...Show All

• Visual Studio Express Editions Line Numbers

  Hi there, I'm trying to create a nice basic text editor for learning/educational purposes. Basically been working on the basics and want to add more and more advanced functions as I go and learn. So I've come to a point where I want to add line numbers down the left hand side of a text box which indicates what line the user is typing on. Just like in the VB interface and other software such as Dreamweaver and Notepad++. I have no clue how to do this. I'm fairly new to this whole thing. I'm using Visual Basic 2005 EE. The last time I used VB was years ago and was verion 6.0. Any help as how to do this would be much appreciated. I'm guessing that I wont be able to use the current text box control Thanks for your time :) ...Show All

• SQL Server 2005 Express - SPs read-only

  I am attempting to use a select SP with params to return data to MS Access. I am using SQL Server Management Express to manage SQL Server 2005. I can create tables, views and SPs just fine. Tables and views return data that is r/w but ALL SELECT SPs return data that is Read Only. Is this normal I am under the impression that SPs can be used to return data to Access forms which is updateable, but I cannot even edit the data for an SP directly out in SMSE, never mind in Access. TIA for any assistance on this, John W. Colby If I understand your question properly, you are using a stored procedure to return a data set to a Microsoft Access form. If that is the case, then the result set is not updateable. In other words, you can't run a s ...Show All

• Visual J# permission question

  I have a J# class BeanResult which inherits from Object (ie no declared parent class) and it does not have a ToString method so that inherits from Object. PermCalc gives the following listing which shows a permission request from ToString which means that every class will then require UnmanagedCode as every class eventually inherits from Object. What is going on here <Type Name="BeanResult"> <Method Sig="instance void .ctor(string )" /> <Method Sig="instance void setColor(class Color )" /> <Method Sig="instance object MemberwiseClone()" /> <Method Sig="instance string ToString()"> <Demand> <PermissionSet ve ...Show All

• SQL Server How To Update and Concatentate A string In MSSQL

• SQL Server EncryptSensitiveWithPassword protection option cannot be used with DTexec execution of SSIS packages

  Our SSIS packages use the Web Service Task to call services to send email and write package failure data to a department wide database. These Web Service Calls are failing with HTTP 401 errors. It was caused by the passwords for the HTTP connections not being saved when the SSIS pkgs were saved to .dtsx files. I have tried saving the package with a password and the EncryptSensitiveWithPassword protection option. This password can be supplied when the package is called from another package or a package is executed in Visual Studio but cannot be supplied to DTexec to execute the package in a job. DTexec does have a /Password parameter but it is rejected if the package is loaded from a .dtsx file. This appears to be a bug in DTexec. It ...Show All

• Visual Studio Team System Error in Schema Compare - CTP5

  In my database I have several CLR functions in one assembly. I use most of the functions in table to calulate something. A typical table would look like: ID bigint IDENTITY PRIMARY KEY Name varchar(50) Result dbo.CalcSomething(ID) where CalcSomething is a CLR function. When I change the assembly (e.g. add a function etc.), the columns in the table are not dropped, but the CLR functions are re-recreated. Since these functions are in use (no dropping) the script will fail ever time. Would be nice to fix this in RTM EDV Gradl - Has your issue been resolved with CTP6 If it has not been resolved, then please provide the additional information requested by BrianKu and we will see if we can diagnose the pr ...Show All

• Windows Forms Formatting text in rich text control

  Is it possible to format the text (such as bold, italics etc) at the time of entering the strings into a text control, not thru code but via the text field on the control's property page You can probably just get away with using rtf_cvText.SelectionFont.Bold = true ; do the trick for bold. As you will have all got the user to hightlight the text in the richtext box . The above code does a search through to highlight a word in a rich text box. Goodluck off for a beer now ;-) Have a good weekend. James ...Show All

• Smart Device Development ActiveSync Development

  Hi - I have developed a little application for my brother who is a Sales Rep. The application is used to track sales from ordering through to delivery and is relatively simple. I have developed it for his WM5 PPC device and also for his desktop. The next step to make this truly useful is to develop an ActiveSync module so that he can synchorinse his PPC with his Desktop. I have never done this before and whilst I would be OK with the coding the record conlflict/handling logic, i am a bit stuck on the high level method for building and deploying ActiveSync modules.

• Visual Studio 2008 (Pre-release) Problem with DatePicker (Kevin's Bag-O-Tricks - January 2007)

  Hi all, I'm having a problem with the DatePicker contained in Bag-O-Tricks. The situation is as follows: 1. I have a DatePicker in my XAML-file. 2. The Value of the DatePicker is bound to the StartDate (DateTime) of my class: Value="{Binding StartDate}" 3. Now, when I run my app, open the DatePicker and click on a date: nothing happens! I put an event handler on 'ValueChanged', and that event only gets called one, when the DatePicker is created and the value is set to the StartDate. It seems that the control doesn't like it when it's Value is set explicitly, because it won't budge from that value. Any ideas on how I can work around this I'm now working with the MonthCalendar, which does not have this problem, but I would like ...Show All
