• .NET Development Handling .NET Exceptions in VB6

  Hi, I have a question regarding how VB6 handles Exceptions raised from a .NET component. This is the scenario: I have a legacy VB6 app where I am writing some new functionality in a managed assembly and accessing it through COM. Now in the VB6 code is used On Error GoTo extensively and there are places where it is responding to data access errors - the kind that come from a SqlServer stored procedure. Specifially an SP performs a Raiserror(50000,16,1) and the VB6 code (inside the error routine) handles the Err.Number when it is 50000. My .NET component replaces this direct call to the SP but I wanted to keep the VB6 code as it, i.e. still re ...Show All

• Visual Studio 2008 (Pre-release) Changing ProxyGenerationParameters in a Service Reference?

  I've added a reference to one of my application using the Add Service Reference... feature (since it's much faster and easier than running svcutil constantly), but I was wondering if I could customize how it generates the proxy in the same manner that I can adjust svcutil. Specifically, I would like it to reference another assembly (like svcutil's /r) and generate async methods (/async). The XML file ServiceName.map seems to have some options in the ProxyGenerationParameters element, but I can't seem to find any documentation on what they are. Thanks for the post and the suggestion. We are looking at ...Show All

• Visual Studio Express Editions datagridview delete row

  I have a datagridview control that is bound to an access database. At the “ BindingNavigatorDeleteItem_Click “, I have some validations. In some situations, as a result of these validations the program has to stop the delete process. How can I stop the delete process In the bindingnavigator's properties set its deleteitem equal to none. This cause the bindingnavigator to use your code instead of the built in code. In the deleteitem click event I would check if it is ok to delete then call the bindingsource's deletecurrent method of delete the record. ...Show All
