It's become common to put a three-letter prefix onto all object names, to indicate the type of the object being used. This makes it much easier to remember what the object actually is (especially when you're using a lot of labels and text boxes, which are easily confused). The naming conventions that have emerged are as follows:
| Object Type | Prefix | Example |
| Form | frm | frmDictionary |
| Picture Box | pic | picHappyFace |
| Label | lbl | lblTitle |
| Text Box | txt | txtFirstName |
| Command Button | cmd,btn | btnQuit |
| Frame | fra | fraOptions |
| Check Box | chk | chkMakeLogFile |
| Option Button | opt | optColorsRed |
| Combo Box | cbo | cboCompany |
| List Box | lst | lstTravelDestination |
| Timer | tmr | tmrFlashTitle |
| Data | dat | datEmployees |
| Horizontal Scroll Bar | hsb | hsbVolumeControl |
| Vertical Scroll Bar | vsb | vsbTrebleControl |
| Drive List Box | drv | drvHardDiskContents |
| DirectoryListBox | dir | dirTreeStructure |
| File List Box | fil | filFiles |
| Shape | shp | shpBox |
| Line | lin | linBorder |
| Image | img | imgHouse |
| OLE | ole | oleSpreadsheet |
