• Visual C# {"Specified array was not of the expected type."}

  Hi, I'm trying to interface between OPC (OLE for Process Control) and C# using Siemens' OPCAutomationDAServer (comes with a package called PC Access). Now, there are some VB6 examples, and indeed they work perfectly fine. There are many such occurances of the above message. One has the following signatures: VB6: AddItems(x as int, y() as string, z() as long, k() as string, l() as string...) from C# the signature reads as : AddItems(int x, ref Array y, ref Array z....) I tried using the same array types that are in use in VB6, and I tried arrays of objects and I tried System.Array.CreateInstance(). Nothing worked. If someone can shed light on this, I'd really appreciate this! Thanks in advance I ran into a ...Show All

• Windows Forms How to install windows and web application using a single setup file

  Hi, I have two applications. One is a windows application and the other is a web application. I created two msi's for these projects individually.

• SQL Server application error

  My SSIS package will just hang (do nothing) after validation of the package tasks. I realised that it does 2 validation. It then hits "starting exectuing" and then nothing. I mean nothing. It just stays the same. When I look into the logg file, the same message as in the output window. My package has parallel extract of data from the same datasource, but different tables. I dont know if that the problem but i really doubt it because i have done parallel table downloads countless times in version 2000. When i go into the data task window, the source task does no even indicate that its downloading (color yellow). Is there any reason why this will happen Ooo, but the tasks executes just fine when i execute them individually (right c ...Show All

• SQL Server Offline/remote backups

  Hi What is the best way to perform daily offline/remote/off-premise backups of our websistes Sql Server 2005 database I've looked into using SSIS but for one reason or another am having serious problems with this. Ideally we'd like to be able connect over the internet and/or lan and pull the entire database down in one go. Our db is ~600mb so isn't major. We used to use Sql Server 2000's DTS and this worked well, but I'm having a real hard time using SSIS to do the same so was wondering what the other options are Many thanks Ben Hi Kevin The reason we used DTS originally was that it allowed us to backup over the internet. Obviously, upgrading to Sql Server 2005 made SSIS the logi ...Show All

• Smart Device Development AutoSize Label

  I am using VS 2005 and writing a VB.net application for a Windows Mobile 5.0 Smartphone using .Net CF 2.0. I need to determine the text height of multi-line wrapped text in a Label control so I can set the height of the Label to ensure that all text is visible, and then reposition other controls based on the new height of the Label. Unfortunately, CF 2.0 Labels do not have an AutoSize property. I have tried some examples using CreateGraphics and MeasureString such as the following... Private Sub AutoSizeControl( ByVal ctlControl As Label, ByVal textPadding As Integer ) ' Create a Graphics object for the Control Dim g As Graphics = Me .CreateGraphics ' Get the Size needed to accommodate the formatted Text Di ...Show All

• Visual C++ SendMessageCallback or Alternative Example

  Hi all, I am currently using SendMessage in a series of activities that must be carried out in sequence. However, using SendMessage will result in a "hanging" state since it will complete the activities before returning control to the caller. As I I need to perform an activity on the completion of another, the PostMessage method will result in the triggering of a later activity without waiting for the completion of a required activity. SendMessageCallback seems to be able to solve my problem but does anyone has an example on this (e.g. how to call as well as how to declare and use the callback function) Or is there any better alternative such as hooks Regards cleohm Hello ...Show All

• SQL Server Security Update for Microsoft Data Access Components (KB832483)

  I recently reformatted my computer and am using Windows 2000 Professional. I enabled Automatic Update. This morning I noticed that the "Security Update for MS Data Access Components (KB832483)" kept showing up. My records indicate that it successfully installed (several times), but the same update keeps showing up to be installed. I finally disabled the Automatic Update function in order to keep it from constantly reappearing. Any ideas Fix doesn't work for me either. The file on the MS update server is newer than the one available through this link and consequently the system will not update to an older version. However, the current file on the server for KB832483 is 0 (ZERO) bytes and I ...Show All

• Windows Forms The fillerror event will not fire while using strong typed dataset

  I'm using strongly typed dataset and trying to add code to the partial class to fire the Fillerror when the fill command has a conncurrency error.  But for some reason the fillerror event never fires.  I've included the code that I would like to work but I've also tried inserting it into the generated code of the datatset.  Neither approach generated an fillerror event while testing. Here the code striped down to technique example using northwind data table customers. I know the errors are happening because I can iterate though the dataset and show rows with errors and even the datagrid view shows the row errors.  Does anyone out there have any idea or docs specific to this issue Namespace Nor ...Show All
