Easy I thought, this has to be a common problem I will just jump on CodeProject find an example and with a bit of tweaking be running in no time. Now if your here I am sure you now know how little information there is available on this topic so I thought I would add to the very small pool with a complete example of how t...

This document describes a method by which features of Object-Oriented Programming (OOP) can be used in straight C, including Standard/ANSI C, and some variants of pre-ANSI C. The following compilers have been tested:
* Visual Studio 6.x +
* GCC
* LCC
* Turbo C 2.0
OOP constructs are implanted via C macros so that source code is easily readable. Knowledge of OOP is assumed as well as rudimentary knowledge of C++....

There are many articles and applications posted here, but I couldn't find one that could do what I wanted. I don't want to add any plug-in to Visual Studio, or modify any .rc files that the IDE should maintain and modify. I want to add more version info like build date. Some of the solutions given here are good but are not complete. They represent only a starting point to my solution....

A rubber band, or focus rectangle, is a rectangle that tracks with the mouse pointer while you hold the left mouse button. This technique is used to delimit a selection in response to user mouse-pointer input. In the graphics device interface (GDI), these rectangles are implemented by using raster operations (ROPs). However, the System.Drawing method is based on GDI+ (the successor to GDI). GDI+ does not support ROPs. This article describes another approach to implement focus rectangles in the ....

This function takes in a DataSet and file name and writes the DataSet to an Excel worksheet. The code is pretty straightforward. Great thing about this function is that, it's technically an XML file that is saved as an XLS file. So it can be used as either file format. No more leading zero truncation on numbers that look like strings. Example, if you made a tab delimited file and put a field such as "00036" (a field that looks like a number but should be regarded as a string), MS Excel would tru...

A simple table in a relational database is the employees table. This has an employee ID and a reports to ID which is an employee ID. The normal way to fill your tree with this hierarchical information is to query for the root nodes i.e. nodes with no parents in this case null in reports to. Then subsequently query the table for all children of the node i.e. reports to ID equals root employee id. Keep doing this until you come to leaf nodes with empty results. I will describe a better technique t...

When a user places a cursor on a DataGrid cell in order to edit its contents, the grid is placed into an Edit mode state. If the user later clicks on a save button to commit the changes to a database, the changes may not be saved. This occurs because the DataGrid is still in Edit mode. For this reason, I recommend to all developers that the form, on which the DataGrid resides, be used to end the Edit mode session of the DataGrid. You can do this by issuing it a BindingManagerBase.EndCurrentEdit(...
