Sometimes the easiest way to run command line tools from the IDE is through a DOS window. To be able to instantly pop one open in your project directory, use the Tools | Configure Tools... menu command. Click the Add... button, then set the Title field to Dos Window, the Program field to c:\command.com, and the Parameters field to /k $PATH(). Finally, click OK. Now you’ve got instant access to a DOS window in your project’s directory--any time you need it!
Running low on hard disk space? Take inventory of those C++Builder projects you’re not working on at the moment, then delete any files from those projects that have the extension OBJ, RES, or TDW. You also can delete files whose extensions begin with IL. Since these files can become quite large, removing them can free significant space on your hard disk.
When you place a glyph (a picture, generally a BMP file) on a button, be aware that the color of the pixel in the glyph’s lower-left corner will be used as the transparent color. Any pixels that color will be transparent on the button. If you don’t want any transparent pixels on your button bitmaps, you must be sure to use a color in the lower-left corner that you don’t use anywhere else in the glyph.
