• Windows Forms Create a single instance of a Dataset to share across forms

  Paul Ballard MVP answered a posting on how to share Dataset across forms. He gave a great and simple solution but I wanted to extend it. When using the GUI it tries to create a new instance of the dataset. So the first thing I want is it to load the instance into the shared variable so any calls to currentDS would use the current instance. I did this by modifing the constructor call. The next issue I ran into (this is the one I’m having problems with) is when the auto generated code tries to create a new DS. Example: I create a new form and I drag a datasource Datagridview to the new form. The code creates a new instance. Any ideas how to modify the typed dataset to check for any instances and if found use them inst ...Show All

• Windows Live Developer Forums Problems with custom tiles

  I am adding a custom tile using a static map image file on my pc and loading with AddTileSource & AddLayer. The file loads but not only is it not scaled or positioned correctly, but it also gets tiled across the whole background VE image The image is correctly georeferenced in the bounds clause and is based in the northern hemisphere - in the UK. I've tried bmp, png and gif formats - but same result. Is there a minimum bit map image size or lat/long precision issue that might cause this OK, thanks for the responses. No I was not using Mapcruncher - I've misinterpreted how the tiling works. I'll do some more homework! ...Show All

• Software Development for Windows Vista How do I stop execution of one branch of a workflow without effecting another?

  Hiya all I need to write a large workflow containing multiple parallel braches and each branch will contain activities that perform actions and then set their own result to true or false. Just prior to completion of each activity I want to test the activity's result variable and if it is false, move no further down that branch. All other parallel activities should continue however. Can anyone advise me on the best method to achieve this Do I need to programatically remove further actions Thanks Michelle x Isn't it much simpler (and easier to manage) if you implement those parallel branches as different workflows ...Show All

• SQL Server How to restrict a custom component to be used only in the event handler tab?

  Hi, One of my plan is to develop a custom task compoent to log the errors into the destination provided as paramter to the component. Now how can I restrict the use of this component in the event handler tab only. can something like this be done Also extending this a little further, is the below thing possible The custom component should expose custom properties which should allow the user to add the destinations for logging the errors. It will be a predefined list (window event log, text file, sql table etc) and the user will be allowed to check what all he/she wants. Then if the user has selected sql table then ask for the oledb connection and the table name, if text file is selected the ask for the path of the file. Apology ...Show All

• .NET Development Simple Update from a VS 2005 vb project to an mdb?

  Hi all, New to Visual Studio, and only have experience with asp and access. The problem I have is this. I can call nearly anything out of my database that I want, but for the life of me, I can't update even a single field. Now the worst part is this. The little program I'm working on to do the data access is just a simple console app, which passes the data on to clients. All is well except, how do I code an update to a field. For example, to update the field Email in the Clients table with a variable passed through dimmed as a simple string This is an example of the code I am using for my general select querries: Dim conn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Delirium.mdb" Dim cmd A ...Show All

• SQL Server filegroup auto-growth - know when it happens?

  Hey guys, I'm running SQLServer 2000. I am in the process of looking over our current filegroups and providing reports based on file size increases. One thing I'd like to know is when (date and time) a filegroup last "auto-grew". Is there a way to know when this occurs thanks, Jason Derek, Thanks for the info. I should have re-worded my question I think: Is there a way to know when the date/time a filegroup last auto-resized Let's say it auto-resized last friday, is this timestamp stored somewhere Profiler would tell me only if I was running it at the time of the resize. I'm trying to correlate the time of an error with the last time a large filegroup resized. thanks Jaso ...Show All

• Visual C# How to return properly from an eventhandler (or do something approximating the same thing)

  Hi! In my code, I need to return from an eventhandler function (function for handling the click of a button), and I can't figure out how. I think this is impossible. I'm not sure. But either way I can't figure out how to redesign my code to work around that problem if that is indeed an issue. Here's the code in question: [code] private void BtnConnect_Click(object sender, EventArgs e) { Connect(); return; } private void Connect() { Socket = new NetFXSocket(false, "82.116.68.153", 1345); UserState = new StateObject(0, Socket.Listener, 1024); if (Socket.Connected == true) { LstConnectInfo.Items.Add("Successfully connected to login server!"); } else ...Show All
