• SQL Server import data

  Hi, I would like to create something i.e. a Job so that the .txt files can be imported into a sql server 2005 database tables. The system has to be flexible so that I can tell it where the .txt file (Source) is and to which database I want to import to. This system has to sit outside sql server, so I guess I can not use something like DTS Any ideas please Thanks ...Show All

• Visual Basic trying to understand classes, module, subs, functions

  I would like to know the differences between a class and a module, and the difference between a sub and a function. I know how to use them. I've been programming for years. But I would like to know the deep details of them so I know where and when to use them. So I can have the most efficient programs. Thanks sub and function is an artificial construct so that VB can avoid having a void return type. Apart from a function returning a value, there is no difference. ...Show All

• Visual FoxPro Windows Service

  How create Windows Service in VFP 6 To run a VFP application as a service you need a helper application like SRVANY.EXE from the Windows Resource Kit. However, VFP 6 is not the most suitable version to do this. While you can turn a VFP 6 EXE into a service, it's very difficult to make it run stable, because VFP 6 was designed with desktop applications in mind. VFP 9 is much better in this regard. ...Show All

• Visual C# Interlink with libraries developed by other languages?

  Hi, there, I am just peeking through the door of .net stuff and want to see if we can adapt to it. I have some questions to ask. We have some code developed in Embedded C++, libraries and executables. I wonder if it's possible for an Embedded c++ project link to a library created by .net, using visual basic or c# On the other hand, can a .net project using visual basic or c# link with libraries created by eMbedded c++ Thanks a lot in advance.

• .NET Development Errors creating new data source

  I've been writing OOP code for 10+ years, and am now excited to learn C#. To help me get going, I recently installed Visual Studio 2005 b2, and have been studying ADO.NET & working through some MS Access projects. I've followed several tutorials on the Data Source Config Wizard, searched MSDN and other online sources, but have come up dry trying to figure out why, whenever I click the Wizard's FINISH button, I get this error: "An error occurred while creating the new data source: Could not get type information for 'MyProject.MyProjectDataSet'."

• Visual Basic Form Switching

  Hello all, I know this is a real n00b question, but I was wondering if someone could advise me as to a better way of doing my form switching without creating a new instance of a form each time. I know usually you can just go Dim F as new Form2 F.Show But that creates a new instance of Form2. What I'm trying to do is to have a permanently open version of Form2 that I can access at any time. The reason I want to do this is so that I can keep all the information stored on that form (text box contents, etc) available for use later if the form is closed and re-opened again. I found a method to do this, which was to create a module and ...Show All
