If you enter 11 for instance into the year component of the date then tab off the control the text returned to the validation function is the text before the year was entered rather than the new text.The problem can be overcome by making the control invisible then visible. This has been the case since Visual Studio 2003, it would seem to be a bug.
View 1 RepliesIs there any possibility that I can put this large chunk of code to a function so that I can call and verify the input without having to repeat the code for every textbox.keyPress event.
Here it is:
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
With e
If IsNumeric(.KeyChar) Or .KeyChar = "[" Or .KeyChar = "]" Or .KeyChar = ";" Or .KeyChar = ":" _

I have two datetime pickers that when changed call a function that validates the two dates and changes them as needed. This currently causes a loop where the function changes the dates on the datetime pickers that triggers the function again...
So I would like to disable the datetime pickers valuechagned function while the function runs then re-enable it after it makes the required changes.

Im trying to use DateTimePicker function and save the date to an access database. Everything is working somewhat how I want it to but not 100% yet. Here is my problem. When the program is running if I click on the datetimepicker and select a date and click my save button the date IS saved to my access database as it should.
but if i run the program and don't ever click on the datetimepicker (because it is already on the correct current date) and click my save button the date doesn't get saved to the access database. The closest I have gotten was to enable the ShowCheckBox option, If i run the program this way and select the check box but dont select a date then it will save the date to my db.
But I really need it to be able to save the date to the db without the user ever clicking on the datetimepicker. Is it just a simple line I'm missing? Im pretty new to this but Ill try to explain anything the best I can if you have any further questions for me.
My company uses control numbers to keep track of all of our inventory for every product that is entered into our warehouse.(ex.G123456789, T987654321) 1st Alphabet followed by 9 digits of numbers.Most of the time, these control numbers are scanned into the system by using a barcode scanner but some times these control number are entered into the system manually by hand.People make mistakes and sometimes enter in different control number.i want to be able to code my vb so that when the control number does not meet the critarion then program displays an error message.So i want to check for the first character which needs to be an alphabet and characters 2-10 to be a number.
View 4 RepliesI am trying to find a way to validate my MaskedTextBox control called mskDate which is a short date property. I need to determine whether the user entered a date in the MaskedTextBox control. I cannot use the Not IsDate function because what happens if the user does not make an entry, then the Not IsDate would not work because the user is not required to enter a date. What happens if the user only enters 03/? This would not be considered a date, but a valid date is required. I tried using the substring to see if an entry has been made but it does not work because of the / / format.
View 2 RepliesI have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.
Basically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.
View 1 RepliesI have a question related to asp.net and vb.net. I have a repeater control that I bind some data to and allow users to update/change fields within certain text boxes. I added a validation control to trigger when the user doesn't enter a valid date or the text "TBD". On submit, I want to go through and highlight each field where its corresponding validator is not valid. This is my current code, but I am lost as to how to find the text box control.

View 1 RepliesWasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
is it possible to set the datetimepicker control's borderstyle = none? 2nd question, how to use 32bit api functions in 64bit vb2010 express beta 2?

View 1 RepliesWhat is the best method to do data validation? I want to do data validation when the user exits a control so that he gets immediate feedback. I can use the Validating event or the Leave event for that. The problem is, that if the user doesn't know the right answer, and just wants to click the cancel button and leave the form completely, it won't let him. It continues to give him an error message until he completely deletes his answer. Very frustrating. Does anyone have a good method for doing this?

I am having the following problem, when the user wants to use the DateTimePicker (DTP), the date box shows in the middle of the screen. Then if the user wants to select a date he cant, instead the date box goes away and the DTP value remains unchanged. This is not always happening, sometimes it works fine and sometimes this happens.Please go to the link below for an image (you can see that the DTP control is on the left while the date box is to the right):[URL].. application is being run from a server to a local client on the user machine, I dont know if this has anything to do with it.

View 11 RepliesI am developing with VS2010 VB.Net and a SQL '08 dbase. I have a DateTimePicker control that by default displays the current date. If you ignore the DTP control and accept what the default is and save the record, in the database table, the value for the date is 'NULL'. I delete the record out of the database and re-create the record in the UI, but this time, I click on the DTP control and actually click my mouse on the current date or any date and then save the entry and it saves to the database properly. I guess what I am after is if a user instantiates the UI form to perform data entry and accepts the current date in the DTP control without clicking on the control, the value is saved properly to the database.
