Validating A Date Picker In Vb6.0
I'm still knew in vb and would like to know how to validate a date picker.
For example I have a date picker in one of my forms and would like it not to allow the user to choose a date before last year. A typical example I'd not want the user to choose 1890 as the year of birth. Thanks in advance

Validating Server's Date Against A Date In An MS Access Database
I'm trying to redirect a user based on what date the field "expires" in my MS Access 2K DB has - This section is where I want to redirect to a page if the expires date in my database = today.
I'm selecting the table above ( rsUser.Source = "SELECT user_username, user_password, expires" ) but I don't think that the Sub is written right.
currentDate = Date
If expires = Date Then
redirectLoginSuccess = "expiretoday.asp"
I'm new to VB; the ASP page I'm calling this through just skips this routine - which means I didn't do it right. Any suggestions?
Date Picker Control Doesn't Show Current Date In Field
How do I set the display date in the Date Picker control field ? MSDN says that it should return the current date by default, but it only shows the current date highlighted in the drop down calendar.
The control shows the date when the control was created and added to the form.
How do I set the date at form load ?
dtpicker1.value = ? ' how do I call current date ?
Date Time Picker Control: How Do Set The Displayed Date To Null?
I have a front end database form with date fields using the MS dtp control. The fields are unbound, but populated using a data class. The problem is that on many occasions the date field is Null, ie no data available. On display the dtp control always defaults to a set date, usually today (this is a property function of the control). What I can't seem to do is to display no date, or to delete the date displayed. Any thoughts would be very gratefully recieved. API perhaps?
I'm trying very hard not to have to write an Active-X control based on the dtp (mainly because of multilingual support and different localisation issues regarding dd/mm/yyyy (used by 90% of the world's population, and mm/dd/yyy - used by the remaining 10% in the US - sorry just had to get that jibe in for those of us who despair at having to go in to custom formatting in Excel simply to get dd/mm/yy )

Validating A Date
What sort of thing would I need to put in the validate event of a textbox to make sure that only a date between two certain dates could be added? Thanks.
I have a textbox for entering date in the form. i want to format it so that if user enters the date without the slashes or enters in incorrect format that it gets correct automatically. can somoen pls help me with this.
if someone enters 812005 i want it to be converted to "8/1/2005".
or if someone make a typo like 81/2005 i want to be corrected or display give a message to the user.
Here's a strange behaviour of the IsDate function that i am encountering in my VB Application.
This function is used in my code to validate date on lost focus. This function all this while i assumed was working fine. While testing i found a strange behaviour... here are the steps:
1. In my regional settings Location is - English (United Kingdom)
2. Short Date: dd/MM/yyyy, Long Date: dd MMMM yyyy
3. In Vb, the function is as following:
Private Sub txtApptDate_LostFocus()
If Trim(txtApptDate.Text) <> "" Then
If IsDate(txtApptDate.Text) = False Then
MsgBox "Invalid Date!!", vbInformation, App.Title
txtApptDate.SelStart = 0
txtApptDate.SelLength = Len(Trim(txtApptDate.Text))
4. In the front end enter the following dates:
* 09/12/2004 (Is valid. Passes through)
* 09/13/2004 (Is Invalid. but, still Passes through)
* 12/13/2004 (Is Invalid. but, still Passes through)
* 13/13/2004 (Is Invalid. Displays Invalid Date message)
* 13/12/2004 (Is valid. Passes through)
* 13/10/2004 (Is valid. Passes through)
In the above sample dates you will notice that some dates are invalid according to the dd/mm/yyyy format but they still pass through as valid dates. Why is this happening? at some instance the isdate passes through mm/DD/yyyy and in some instances it passes dd/MM/yyyy?
This is rather strange and i have never noticed this before in my development years in Vb...
Has anyone encountered the same? knows the resolution for it?

I am needing to validate that numbers entered into a text box are a valid date. Example 12122000 (12/12/2000), would be valid, but not 13122000 (13/12/2000). I tried using a DOS program's routine, but it won't work. "Ending" is the variable holding the date. I get the invalid Month MsgBox every run. If this can be fixed, please help. Otherwise, suggestions are greatly appreciated!
private Sub ValiDate()
If Val(mid$(Ending, 1, 2)) < 1 Or Val(mid$(Ending, 1, 2)) > 12 then
MsgBox "Invalid Month, Please enter again."
If Val(mid$(Ending, 3, 2)) < 1 Or Val(mid$(Ending, 3, 2)) > 31 then
MsgBox "Invalid Day, Please enter again."
If Val(mid$(Ending, 5, 2)) < Val(mid$(date, 9, 2)) - 2 Or Val(mid$(Ending, 5, 2)) > Val(mid$(date, 9, 2)) + 2 then
MsgBox "Invalid Year, Please enter again."
Date Difference Using Date Picker
What is the secrect to finding the difference in date using the Date picker? Here is my inaccurate code:
Dim DaysRented as Long/Date/?
DaysRented = DateDiff("d", dtpEnd.value, dtpStart.value)
DaysRented value continues to be -1 if a long, integer and a strange date if declared a date. What's the secret to this?
Validating / Calculating Date
I'm having the following little Excel problem.
My worksheet has two columns, all celss defined as "Date".
Column A has dates on which a sales representative visits a certain company.
Column B has dates on which a letter has been sent to this company.
Now I want to make sure that all dates are entered corectly.
For example :
If the date value in column A is "higher" then the value in column B a message box should appear, telling the user that a wrong entry has been made.
Is there a simple way to do this using (for example) "Validating" in (Excel) VBA ?
Any help would be most welcome.

Validating DATE And Numbers
i have two questions.
ive tried two ways..
1) ive tried the masked edit box using ##/##/##
it works except when i press ADD (which is suppose to clear fields) all the other fields clear except the masked edit box.
how do i get it to clear the masked edit box to ##/##/##
for example from 10/11/03 to clear and show ##/##/## when i press ADD
2) ive validated the date text box using ASCII keys so that the user can only enter in numbers, no alpha characters.
but it wont let me backspace or delete after entering number... how do i make it so i can delete the number ive entered????
I am using DTPicker and want to be able to do 2 things:
1. Display a blank or null date (without using check box)
2. Skip forward and back by years as well as months.

About Date Picker In Vba
Hi there. I recently added a "monthview" tool to my excel application in vba (by registering "regsvr32 mscomct2.ocx" in which a monthview tool was added to the component tool in the vb editor). However when I used the excel application in other machine, it prompted me with an error message and the application could not be run. Must I install the same ocx file in any machine which is to run my excel application?
How do I get Date picker to show the current date?
I mean as the default start value
DT Picker = Date ?
I have just recently switched from a Tet box to a Date Time Picker> What happens was when the Text in the text box = todays date, a custom form is shown. This was the code I used:
Private Sub txtCustomerName_Change()
If Text1.Text = Date Then
I tried using this code on my Date Picker Control but it never worked.
Does anyone know the solution?
Does anyone know if you can set the checkbox property for the Date Picker to "unchecked"? The default seems to be "checked" with no way to change it.
Thanks a bunch!!!!

Validating A Date In A Compound IF Statement
I need to validate a date entered into a textbox in the form mm/dd/yy by using a massive compound IF statement. If the date is valid, nothing happens but if an invalid date is entered, a message box pops up saying, "invalid date."
this is what I have so far:
month = fulldate.Substring(0, 2)
day = fulldate.Substring(3, 2)
year = fulldate.Substring(6, 2)
If (month < 1 Or month > 12) Or (day < 1 Or day > 31) Or (year > 3 And year < 38) Or (month = 4 And day > 30) Or (month = 6 And day > 30) Or (month = 9 And day > 30) Or (month = 11 And day > 30) Then
MsgBox("Invalid Date Entered", , "Data Entry Error")
I've tried a lot of different things to do the leapyear and non leapyear calculations but nothing works.
Help Needed Validating Date Entries
OK... I've got a grid which the user can enter two cols worht of data.... the first col is a Date... then second is a dollar amount.
checking the amount col for valid data is straight forward... it's either a number or it isn't.
Checking the date is another matter.
We want them to enter the date in a mm/dd/yyyy format....
at the moment, I'm using the IsDate to check for valid dates.... it will catch really bad dates like "12/32/298855"
BUT.... it's not catching things like "7.05.03"... which it translates to 07:05:03AM..... grrr.....
ANy one have any ideas?
Validating Date Entered To Period Entered (which Corresponds To A Date Range)
I am trying to create a macro in excel that compares a date entered (YYYYMMDD) and a period entered (1-13) to see if the date entered matches the dates of the period entered?
(E.g. Date - Cell B3 = Entered 20040412 (YYYYMMDD)
Period - Cell B4 = Entered 12
Since period 12 respective dates are 20040404 thru 20040501 macro should return message saying valid date and period
Date - Cell B3 = Entered 20040412
Period - Cell B4 = Entered 11
Since period 11 respective dates are 20040307 thru 20040402 macro should return message saying invalid - date and period do not match)

Date Time Picker
I need to have the year from the date time picker to be formatted as YY. Could someone help me with the syntax on doing this?
Also, Is this an efficient/logical way of doing this? I have 3 separate text boxes in which the user can either enter the date in or select it from the DTP form.
Private Sub dtpickerLbl_Click()
monthTxt.Text = dtpFrm.dtpCal.Month
dayTxt.Text = dtpFrm.dtpCal.Day
yearTxt.Text = Format(dtpickerFrm.dtpCal.Year, YY) ...This ain't working...
Date Time Picker
Can the value of the date time picker be left blank? My reason for asking this is so that I can use this for entering Date of Birth and want to default it to blank.
