• .NET Development Call client's object method/property from remote object

  Here's the scenario: - a client apps (client.exe) and a server apps (server.exe) which will run on separate AppDomain - the server host a WellKnownServiceType called MyServerObject using SingleCall mode. - the client have an instance of MyClientObject (reside on client's AppDomain) - then, the client will remotely call MyServerObject.SomeMethod() The question: - How I can modify some value inside MyClientObject (which reside on client's AppDomain) from MyServerObject which reside on the server's AppDomain I tried to pass MyClientObject as a parameter to the MyServerObject.SomeMethod(MyClientObject obj), but it don't seems to work either. Here's the code snippet (simplified version): server.exe: ChannelServices.Regist ...Show All

• Visual Basic storing excel.xls files in db - truncated

  My application read/writes binary file data from the filesystem to the data base and sometimes back again This is all in vb.net 2005/sql2005. It works fine except for excel file, .xls. They are the exception. All data is stored in a varBinary(max) column. Images, pdf's, word docs, whatever all work fine, but not excel. Even very small test spreadsheets of 5k fail. "binary data would be truncated" is the exception. Has anyone experienced problems with this type of file A bytes a byte, I thought I call the procs like this: (1) entry.Blob = ReadBinaryFile(tbLookup.Text) (2) If Not EntriesDB.AddEntry(entry) Then MessageBox.Show("The Entry was not added.

• SQL Server Allow user to choose grouping order?

  I have a report which is working off a dataset with 5 columns. Date, Type, Color, Value1, Value2 We would like to set up a report such the user viewing the report could drag and drop column headers and set up grouping in whatever order they want. What would be the best way to do this Is it even possible, or do we have to create a separate report for each combination For example, One report just groups by Date and Type. They might also want to group by Type then Date. Other times we want Date, Type, then color. I used to run the reports in a third party grid which supported this, but since it was all client side, it was very slow for large datasets. You can change the grouping through report parameters.

• SQL Server MDX - Filter by one date dimension and report on another date dimension

  Hi, I have a fact table in which i have more than one date dimension. The fact table is a periodic snapshot fact table.

• SQL Server Creating tables with SQL Scripts

  In sql server 2003 I would create tables with generated sql scripts. This way I could easily create duplicate dev environments. Now in SQL 2005 Dev edition I try to run my scripts to create tables. I create a db [MSS]. They run successfully but there is no table created. (example script)USE [MSS] GO /****** Object: Table [dbo].[KataNames] Script Date: 08/17/2006 13:28:14 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[KataNames]( [Kata] [char](30) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [SequenceId] [int] IDENTITY(1,1) NOT NULL, [Description] [char](500) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [Style] [char](25) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ) ON [PRIMARY] G ...Show All

  I develop an application with visual basic .net 2003 and my problem is that my program it has to known when a weighing machine gives the weight value from a serial port and read it. I will be grateful if someone can help me.   Ryan, You are missing the point. He said VB.NET 2003, and SerialPort is part of 2005. So there are 2 solution 1. Update to 2005. 2. Write your own class to handle serial port with help of PInvoke. There is some available source on the net for that... ...Show All

• .NET Development .NET 3.0 breaks printing subsystem on non-english XP / VERY ugly effects

  After installing .NET 3.0 on non-english XP two things will break parts of the printing subsystem: - parts of XPS are installed in English, i.e. unidrv.dll / unidrvui.dll / unires.dll etc. are non-localized As a consequence Printing dialogs of all unidrv.dll-based printer drivers show mixed output localized/english. And the default Input Tray is set to 'Automatically Select' even on a german XP which leads to strange effects like printers suddenly asking for paper in the Manual Tray instead of using Tray 1 as usual. - unidrv.dll / unidrvui.dll / unires.dll etc. are Windows Vista DLLs and incompatible with many XP Printer Drivers As a consequence some printer drivers will print all pages of multi-page documents on one sheet, all ...Show All

  Where can I find info explaining how to connect to an existing Access Database. The only stuff I have found so far is for connecting to SQL Express 2005.

• .NET Development Time zone conversion problems

  Hi, I'm trying to parse a date time string that is always in ET time zone. The resulting time should be converted to local time. I could do that by backadjusting the ET time and converting to UTC. However, the issue is that I don't know if ET is currently in DST or not, so that I don't know how many hours I have to backadjust. Is there a framework built in way to get the UTC offset for any time zone Thanks, Tom There seems to be no "easy" solution for this problem. I was once tasked to write a "simple" report that displays statistical data for a Web app for one day; problem is the defintion of one day in relation to a specific region is different depending on what time zone the person ...Show All
