Part 1 of “Programming with Stored Procedures” demonstrated how you can edit and test stored procedures without leaving Visual Studio .NET. In this part I will demonstrate how you can codify the analogous steps to incorporate stored procedures into your Visual Basic .NET applications. In this article I will demonstrate how to: Externalize connection string […]

Printing line-by-line without a Document/View framework . Environment: tested on VC6 SP4 and VC7 Introduction Do you still remember the times of the LINE printer (a dot-matrix printer)? Printing was still simple in these times. You simply sent print lines to the printer and lines in exactly this order were printed out. Searching for a […]

Environment: Visual Studio .NET (version 7.0.9466), .NET Framework (Version 1.0.3705), Windows XP Introduction The .NET framework provides a very useful feature that allows an application to store and retrieve data on a per-user basis. This new Isolated Storage mechanism replaces the previous methods of storing such data in Windows .ini files and the system Registry. […]

Environment: ATL, COM, Visual C++ 6, MFC, Microsoft Outlook Express, Win XP, Win 2000 Introduction During software development, I have seen many applications that require incorporating e-mail support. I remember once I was to develop an application that sends e-mails at a specific time to specific people with the customized messages. For that, I developed […]

Environment: VC6/VC7 This CSysInfo class makes it easy to get various system information, such as: OS version (for example, Windows 2000 Terminal Server or Windows XP Home Edition) CPU type Total amount of physical memory and memory usage IE version (very useful for XML-enabled applications) ADO version Does the […]

Stored procedures are an excellent way to optimize complex business solutions for database applications. In this article I will demonstrate how you can edit and run stored procedures in Visual Studio .NET and how to incorporate them into your Visual Basic .NET applications. ADO.Net has made this aspect of database programming accessible to all. In […]

This article was contributed by Jens Winslow. Environment: Windows and Dialogs, VC++ The credit for this solution goes to Markus Plaum, who was the one who actually figured out how to do this. Thanks, Markus. While creating a program to draw a data view with a scale, using a splitter window with scale in top […]

At the beginning, we decided that a normal ASP script that read data and gave it to that applets would be useful. Unfortunately, it wasn’t! The Web server crashed […]

Environment: VC6 SP4 The included source code is for a Visual C++ add-in that offers a number of different functions: Comment Function ///////////////////////////////////////////////////////////// // STDMETHODIMP CCommands::MarkTCommandMethod() { AFX_MANAGE_STATE(AfxGetStaticModuleState()) OR ///////////////////////////////////////////////////////////// // // Name : CCommands::MarkTCommandMethod // Return type : STDMETHODIMP // Comment : // STDMETHODIMP CCommands::MarkTCommandMethod() { AFX_MANAGE_STATE(AfxGetStaticModuleState()) Insert Modified ID (Name) and Date Before […]

Environment: VB.NET Introduction to ADO.NET Microsoft has improved significantly in data access functionalities over the old ADO model; that new model is called ADO.NET.

A solution is to implement a number of simple combos or checklist boxes. This has the disadvantage of not allowing multiple choices (combos) or taking a lot […]

Environment: VC7, VC6, WinXP, WinME, Win98 I am pleased to submit a tutorial to CodeGuru; I have benefited very much from the generous and helpful resources here. This tutorial tries to explain how I developed Undo/Redo capability for my own applications. It works very well for me. Perhaps others here might find it useful. I’ll […]
