• Windows Forms Problem somewhat solved

  I'm running into this same problem: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=356806&SiteID=1 Databinding seems useless. The idea of the disconnected data model is a really difficult process, mainly because of relational databases. Many of my tables have identities, and if multiple people are hitting the database at once, there is no guarantee that the identity generated in your datagrid is going to be the same when you actually submit the in memory dataset to your database. This makes it a real pain to update related records. Can anyone shed some insight on complex databinding with identities and relationships Perhaps, someone has some good documentation on some methodologies used to create windows forms applicati ...Show All

• Visual Basic Timeout on first load with SQL Express

  I have an application that on the first boot, almost all the time, it will give a timeout error for the database. Has anybody else had this problem, and is it possible to fix Thanks! Hi Dave, I have the same problem too, and although I don't really know the cause/solution, I work my way around it. I don't think it is the cause of an Antivirus/Firewall program. I've tried it on my machine (with AV and Firewall) and on my parents machine (without). And both had the same error. On my form which needs a SQL Express connection, I use Try - End Try. In the catch section I place the whole thing again like: Try 'The Code for the adapter here: Me.MainTableAdapter.Fill(Me.LogbookDataSet.Main) C ...Show All

• Windows Forms Slow in form display

  Is there any method to speed up the display and rendering of Windows Form In my application, my Windows forms containing around 50~150 controls. There are also some navigation button to hide one form and display another one. The delay occur during form showing up. As I'm developing a POS, such kind of delay is not preferable. Is there any workaround to speed this up Thanks for your suggestion. I will try to remove some labels and make use of the Paint event. However, I got a lots of buttons in my Windows Form. How can I fix them I don't think it's wise to paint the button by myself as I'll lose a lot of default UI behavior (I mean the outlook). Meanwhile, will it hard to manage a Windows Form with both control and custom Paint event ...Show All

• Smart Device Development The remote connection to the device has been lost.

  Hi, I get the following message when I run my application on my pocket P.C. It happens randomly. Sometimes it works fine. Other times I get this message. I am not using any breakpoints.

• SQL Server Microsoft SQL Server sq

  I took over a website for another consultant. This web site has a sql server database. I can ftp my programs to the site and run them, but I am not sure how I look at the data on the server database with Microsoft SQL Server Management Studio Express. How do I tell smse where the database is located Thanks you would simply enter the IP address of the server the runs the site (and presumably the sql server). 2 things you might have problems with.... (1) is the server running Sql Server 2005 (Express) (2) if you still cant connect its possible that there is a firewall in the server that is blocking the connection. ...Show All

• Visual Studio Express Editions Reinstall help files?

  I recently installed two additions to VSC#2005EE: 1) The Service Pack 1 2) The .NET 3.0 (aka WPF), which created some new templates I'm not certain which one was responsible, but one of these two deleted most of my help files by way of 'merging' them. Since I'm offline more than I'm on, and I loved my original local store of help files, is there any way to get them back short of complete removal & reinstall (No, I don't want to change to online help. I need to be able to access it wherever I have the laptop at that given time/day. I've tried specifying 'local help first', but most of the index and content is just gone.) Okay, I figured it out. By accident, I ran across this page in the index: Visual S ...Show All

• SQL Server Programmatically Data Conversion component creation

  Hi there, I have created a package which simply imports data from a flat file to a SQL Server table. But I need to incorporate a data conversion component by which I may change the source-destination column mapping programmatically. So what I thought that I need to add a data conversion component into the dataflow task. After adding this component (I found its component id as {C3BF62C8-7C5C-4F85-83C3-E0B6F6BE267C} ) I have created a path which establishes the mapping between output columns of source component and the input columns of data conversion component. Now I am not sure how to establish the mapping between the data conversion component’s input column collection and output column collection. I am giving my code snippet her ...Show All

• Visual Studio 2008 (Pre-release) Hosting xbap in a non-asp.net web site?

• .NET Development What is the 3.0 runtime going to look like?

  I'm looking at (and have installed) the RC1 of .NET 3.0 and it seems empty. Are LINQ, ADO.NET Entities, WCF, etc.. all shipping as individual libraries / downloads or is this just how it is for pre-release so each project can release betas as needed I've been looking around for a good explanation of "what versions of everything to download" and I haven't been able to find anything. Right now I can't seem to build ADO.NET Entity projects that use LINQ because of version dependency problems, and there seems to be a project-type in Visual Studio for each library I plan to use.
