• Smart Device Development Disappearing Inputpanel

  Hello, My problem is: After Messagebox.Show() System.WindowsCe.Forms.InputPanel has gone, it can be back only on new instance of Form, I use .NET Compact Framework 2.0 and ToolBar with image buttons near inputpanel.

• Software Development for Windows Vista Writing Resource Managers for System.Transactions to MTS/DTC and XA

  We are trying to write a durable resource manager that works with System.Transactions. I need to use mts/dtc talking to xa where the actual database is on a remote system. I have read all of "Implementing a Resource Manager" and everything else I could find but could not figure out how to couple the .NET resource manager with xa. We have working distributed transaction code for OLEDB and ODBC using mts/dtc and xa. I really need sample code and/or hints about writing such a resource manager like this. If I understand your approach correctly, not quite -- and the issue really does end up revolving around recovery. Again, I think what you're trying for is roughly: App -> your bridge resource -> XA res ...Show All

• Visual Studio Underwhelmed by Sandcastle

  I've noticed that the feedback on Sandcastle has been generally positive. Maybe I'm in a minority of one, but I felt I had to get this off my chest. <rant> Having initially dismissed the first Sandcastle release as immature, I've come back several months later to try out the December CTP. My requirements are, I believe, simple and mainstream. I want to generate documentation for a product consisting of a few class libraries and integrate it with VS2005 help. The document should be generated automatically as part of the build process. With .NET 1.1 and VS2003, this was easy to do with a batch file that calls NDocConsole, which in turn generates a configuration file for the easy-to-use H2Reg utility. I can then call H2Reg in a ...Show All

• Smart Device Development Deploying CF Project to run using Full Framework for Desktop

  Hi everyone, I currently have a CF project in VS2005, but I would like to know how to change the project to target the full .NET Framework instead. My goal is to have my CF app run on the desktop. I have searched for similar questions, and somebody mentioned that a Deploy to Desktop feature was in the VS2005 Betas but was removed for RTM. Supposedly the feature is slated to reappear in the VS2005 SP1, but I couldn't find it in the latest Beta of SP1. Does anybody have any suggestions Thanks! Kirupa Thanks for the quick response Ilya. It seems as if I will have to change a lot of code to remove some CF-specific classes. Is there a way to create an executable of my CF app and have it run on the desktop instead :) ...Show All
