• Visual Studio Express Editions Database q's when running .exe app

  In an attempt to ellicit a better response I have rephrased my topic. The problem remains the same. When I open the CKApp.exe file located in the /bin/debug folder it runs fine and appears to save my data to the database e.g. ckapp.mdf/tables/dailymeasrements. But when I re-run the app the data is not there. Here is the code I believe to be important. Dim MeasDV As DataView = CkAppDataSet2.DailyMeasurements.DefaultView Dim MeasRV As DataRowView MeasDV.Sort = "MonthDayYear" MeasRV = MeasDV(MeasDV.FindRows(measDate).Length - 1) MeasRV.BeginEdit() MeasRV("Temperature") = Double.Parse(Temperature.Text) more ad ...Show All

• Software Development for Windows Vista Custom Activity - Errors Best Practice

  After looking at some examples and browsing the forum I could not find much information on how to handle errors in side an execute method. For example, I go to retrieve something and it is not there. At this point the activity can not complete. What is the best practice at this point, throw an exception or just set the cancel status Thanks Returning a status of Cancelled will indicate the activity was not successfully completed; whereas returning a status of Closed will indicate the activity completed successfully. If you cancel, subsequent activities in the flow will be allowed to execute.  If you throw, the workflow will termina ...Show All

• Architecture Doing what Microsoft does, not what they say to do… DNA, SOA, Software Architecture, VB.NET, CMMI, Agile Development

  Trying to weed through all the marketing driven releases from MS is not an easy task, but in the end it is something that always needs to be done. In this blog I discuss DNA, SOA, Software Architecture, VB.NET, CMMI, Agile Development - Doing what Microsoft does, not what they say to do… I would like to know if you are going through the same problems I gave up trying to weed through Microsoft's patterns and tools a long time ago. Bear in mind that MS is extremely popular in the novice and unproffessional developer community and this reflects on the patterns they provide. As for 'Doing what Microso ...Show All

  I am using a number of (public) property statements (.NET 2003) to pass variables between classes. All are working fine except for the statements where I am passing 2D arrays. When I step through the code, the set is working fine, when I step into the get, the values are empty strings. Three classes are involved, a .dll is setting the values in an intermediary class and the .exe is getting the values.

• Visual Studio Team System Team Build and ClickOnce

  How can I deploy an app via ClickOnce using Team Build I read somewhere about replacing SolutionToBuild with SolutionToPublish, but that doesn't seem to do anything special. I'm using the RC. Thanks Though we do not have an out of box way to do that we can do it with a simple work around. We can overload the target AfterCompile in TFSBuild.Proj to call MSBuild Task Publish and can pass the PublishDir property as desired. Here is an example of what I tried < Target Name = " AfterCompile " > < MSBuild Condition = " '@(SolutionToBuild)'!='' " Projects = " @(SolutionToBuild) &quo ...Show All
