- Use these routines if they will help you. You can use,
- modify, copy, or distribute with a clear concience.
-
- Visual Basic 1.0 input routines
-
- These routine are use two events for each text control.
- There is a Sub for the KeyPress event and a corresponding
- Function for the LostFocus Event. The KeyPress (KP) routine
- restricts certain keystrokes and the LostFocus (LF) routine
- validates the data entered in the text control and assigns
- the entered data to a variable.
-
-
- Date
- Sub DateKP(ThisControl, KeyAscii)
- Function DateLF$(ThisControl, EarliestDate$)
- Format of EarliestDate$ is "yymmdd".
- Accepts date enter in one of the following formats:
- 60491, 060491, 06/04/91, or 6/4/91
- Returns date in the format 910604.
-
- MultPrice
- Sub MultPriceKP(ThisControl, KeyAscii)
- Function MultPriceLF$(ThisControl)
- Used to accept retail prices. For example 3 for $1.00.
- Accepts and returns in the following formats:
- Input Returns
- 149 01/01.49
- 1.49 01/01.49
- 3/49 03/00.49
- 3/.49 03/00.49
-
- Point2
- Sub Point2KP(ThisControl, Length%, KeyAscii)
- Function Point2LF(ThisControl, Min#, Max#)
- Accepts number with two digits to the right of the decimal point.
- Maximum length = Length%
- Minimum value = Min#
- Maximum value = Max#
- Example 123.49
-
- Point4
- Sub Point4KP(ThisControl, Length%, KeyAscii)
- Function Point4LF(ThisControl, Min#, Max#)
- Accepts number with four digits to the right of the decimal point.
- Maximum length = Length%
- Minimum value = Min#
- Maximum value = Max#
- Example 123.4978
-
- Str
- Sub StrKP(ThisControl, Length%, KeyAscii)
- No LF function for this routine just move text to string in
- LostFocus Event.
- Accepts string of length less than or equal to Length%.
-
- UCStr
- Sub UCStrKP(ThisControl, Length%, KeyAscii)
- No LF function for this routine just move text to string in
- LostFocus Event.
- Accepts string of length less than or equal to Length%.
- Converts characters to upper case as typed.
-
- Long
- Sub LongKP(ThisControl, Length%, KeyAscii)
- Function LongLF&(ThisControl, Min&, Max&)
- Accepts long integer amount.
-
- Int
- Sub IntKP(ThisControl, Length%, KeyAscii)
- Function IntLF%(ThisControl, Min%, Max%)
- Same as Long but accepts normal integer amounts
-
- Curr2
- Sub Curr2KP(ThisControl, Length%, KeyAscii)
- Function Curr2LF@(ThisControl, Min@, Max@)
- Same as Point2 but for currency data type.
-
- Curr4
- Sub Curr4KP(ThisControl, Length%, KeyAscii)
- Function Curr4LF(ThisControl, Min@, Max@)
- Same as Point4 but for currency data type.
-
- DateSer
- Sub DateSerKP(Thiscontrol, KeyAscii)
- Function DateSerLF@(ThisControl, EarliestDate$)
- Same as Date but returns date serial number instead of yymmdd.
-
-
- Calling example:
- To call the Point4 routines.
- 1. In the KeyPress event of the text box control with the CtlName
- "Text1" enter the following Sub.
- Sub Text1_KeyPress(KeyAscii As Integer)
- Point4KP Text1, 10, KeyAscii
- End Sub
- This accepts a number with up to four decimal places and up to
- a length of 10 characters.
-
- 2. In the LostFocus event of the same text box control enter the
- following Function.
- Sub Text1_LostFocus()
- CostAmount# = Point4LF(Text1, 1, 1000)
- End Sub
- This sets CostAmount# to the entered amount if the number
- entered is between 1 and 1000. If it is out of range you are
- given a warning message box.
-
- The demo program EDITDEMO.EXE must have "vbrun100.dll" available.
- It comes with Visual Basic or is available for downloading in the
- Microsoft forum's Visual Basic library.
