• Software Development for Windows Vista SQL Persistence, Loading Workflows and Workflow Properties

  I have a workflow that has a bunch of properties on it. One of those properties is the name of the user that initiated the workflow (it is passed into the workflow via the Dictionary<string, object> class. I have SQL persistence working just fine (well, I can't figure out how to 'auto persist', so I am manually calling 'Unload' when the workflow idles), and I run through the list of workflow IDs persisted when my application starts up. What I want to do is access the properties on that workflow (they're public) once I have the instance ID. I just can't seem to find a way to access those properties.

• Visual Basic DataGridView edit causes Form.Show() to crash

  Hi all, I have an MDI called "Question Centre" with a docked ToolStrip that controls the navigation between the sub-forms within it. One of these forms has an editable DataGridView on it. I experience an "Out of Memory Exception" if I am currently in "Edit Mode" of the DataGridView when I click the ToolStrip to swap to another form. The exception is explicitly throw on the form.Show() event in the ToolStrip's OnClick event. This exception does not occur if an uneditable cell is selected. It also does not occur when I jump between editable cells without changing forms. It only ever occurs when I am ed ...Show All

For example: Data_1 for tables Index_1 for Indexes Audit_1 for Audit tables The files for these filegroups would be placed on RAID Disk. Thanks for any suggestions.

• Smart Device Development Using COM attributes in a Smart Device project

  In Visual Studio 2005 beta 2, is it possible to use COM attributes in a smart device project rather than maintaining an IDL file We're just getting started with a smart device project where we need to wrap existing C++ code in COM so that it can be accessed from C#.  We're familiar with C# and managed code, but COM is new to us, and we're looking for the simplest way to wrap our C++ code in COM interfaces. From what we've read, attributes seem like an easier way to do this than using ATL and a separate IDL file. However, we've noticed that the project wizard in Visual Studio 2005 beta 2 for smart device projects doesn't offer the "attr ...Show All
