• Visual Basic Interop Forms and Interfaces

  I am in the process of upgrading our VB6 app to a VB.NET app. I am using the Interop form add-in to do this since we have to do this in increments. All of our VB6 forms implement an Interface "IPanel". I have replicated this in the form we are converting in VB.NET. When I then try to run the following code in VB6 I get a type mismatch error. Dim mfrmCurrentPanel AS IPanel Set mfrmCurrentPanel = New TestInterop.InteropForm1 InteropForm1 in VB.NET does implement the IPanel Interface. Will this not be recognized in VB6 Thanks for anyone who can help. ...Show All

• Visual Studio Manual binding example

  I have a lot of RDL reports that I would prefer not to convert to RDLC. www.gotreportviewer.com mentioned manually binding data sources to these reports, but I could not find an example of how to do this. Does anyone have an example of this Thanks This will only work if the RDL is 2005 version. Rename the .rdl to .rdlc and add it to the project. Using the smart tags panel of ReportViewer select the rdlc file. (Notice that the DataSet, BindingSource and TableAdapter objects are NOT automatically created at this point, unlike in the case of an .rdlc that originated as an .rdlc.) From the smart tags panel, select the Choose Data Sources command. A dialog opens. In this dialog, a list of datasources expecte ...Show All

• Visual C# Data Storage For Distributed Applications

  Hi all, I'm new to C# and have mainly worked with web and server side stuff in the past. I am looking to make an application that can be distributed to people. The coding itself has been fine, but I seem to be having a dilema on how to store the data. I need to store values which traditionally I would have store in for example an SQL or Access database, however if I am to give this out to people who are non technically savvy then this causes a problem. I considered just using something such as a tab delimited text file, but realiased this may cause a major slow down when alot of data has been entered amoung other issues. Is there a way to store data that requires no databases or other requirements than that which is distributed with the ap ...Show All

• Windows Forms Arrow Keys don't move controls in custom forms designer

  Hello, I have a custom forms designer. I've implemented a menu command service like so MenuCommandServiceImpl mcsi = new MenuCommandServiceImpl (); host.AddService( typeof ( IMenuCommandService ), mcsi); MenuCommandServiceImpl is derived from IMenuCommandService. I "think" that the controls are supposed to move when the arrow keys are pressed via the MenuCommands .KeyMoveUp etc. Commands. I've added those commands to my MenuCommand class, but nothing. In all my searching around, I think that the DesignSurface.View is stealing the key press events for the Arrow keys, and should be the one to fire the correct events or preferably move the controls. Have I added the wrong service or is it possibly ...Show All
