Entering a date with an Input Box and validating it to ensure it has been entered in form dd/mm/yy. I have a VB Macro in Excel and I want the user to enter a date in an Input Box in the format dd/mm/yy. The entry needs to be validated to ensure it is valid and if possible in dd/mm/yy format which if not would request another date is entered.
View 2 RepliesSo I'm developing a Windows Forms Application in Visual Basic 2010. The user searches for data and fetches results, updates fields and some other CRUD operations. I want to provide a user input validation. Usual stuff i.e. some fields need to be always numbers>0, others need to be non-empty in order to avoid Null access on some objects and others just need to be some fixed strings.

In my .NET porject, I have to run a lot of validation on 4/5 fields. This validation checks if certain fields have errors, for example: the name field is not allowed to have numbers or symbols. If all these checks are passed, I need to execute a SQL query to pull some data out of the database. I could have it with a lot of nested IFs, and run the function at the end once it passes them all, but this will translate into about 12 nested IFs, and it seems a really bulky way to do it. I have also thought about setting a boolean value after every check, and if the value is 1 then don't run the function, else do. But of course this gets overwritten by other checks that pass.

I'am using the NumericUpDown_Validating event to cancel mouse clicks on the up and down arrows of the control.The idea is that the NumericUpDown control will stop incrementing when the base of a form reaches the bottom of the screen. That works, however the textvalue keeps incrementing. Why does the text keep incrementing and how do I stop it?

View 2 RepliesI have a VB.Net program that manually sends email via the MS Exchange Server. When an email is sent it will always have at least 1 pdf file attached to it. After all the emails have been sent (which could be alot), the pdf files are moved to an archived directory.My problem that seems to be occurring is that some of the attachments are not being moved because they are "locked" by another process. I'm assuming this "other" process is the Exchange server handling the pdf attachment but I'm not positive about this.How can I check to see if the attachment was successfully depositied into the Exchange server?

Function CalcValidation() As Boolean
' Didn't want to leave something out, so I needed a validation to ensure that a selection
' had been made for each component.
[code]....
what I want is the following:
1. I have this form: img1
2. I filled up this form navigating with the tab key. I reach the last cell of the datagridview (dgv): img2
3. now, when I press enter, a new row is adding to the dgv and the first cell of this row has the focus and the cursor is blinking: img3 (while pressing tabs in the dgv, the current cell is always in edit mode, I don't need to do an extra click, I can write immediatly)
4. but my problem is that when I press the left arrow key at the end of the first row, a new row is adding to the dgv in this case too: img4
5. that is what I want to prevent, but the navigating with the arrow keys (switching between cells) should not be disabled, it just should not add a new row to the dgv.
6. and here my related codes:[code]
I think if I press the left arrow key, that fires up the cellvalidating event and after that the cellendedit event. I 'd like to manage this so that if the current cell is the 5th (e.ColumnIndex=5) then it should detect what was pressed (arrow key or enter). If enter then add new row, if arrow key (left) then cellendedit and switch to another cell but in the same row (of course if more rows existing up and down keys are possible).

Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox.

Basically, I have to write an If statement verifying the age put in a textbox, based on a radiobox that is checked.
So, if the radiobox "PG" is checked, the age in the textbox has to be equal to or greater than 12. If "Restricted" is checked, then the textbox has to be equal to or great than 17.
I have a textbox, a standard button and a toolstrip containing a couple of buttons. In the validating event of the textbox i coded to check whether it is blank. If yes then it shows a message 'Enter Value'. When the standard button is clicked while the textbox is empty, it's validating properly and showing the message but when the toolstripbutton is clicked it's not not validating the textbox and no message is being shown. It seems that I gotto write the validation code explicitly in the toolstripbutton_click event which is too troublesome when there are multiple textboxes and toolstripbuttons on a single form. What I want to know is whether the textbox_validating can be fired while the toolstripbutton is clicked? Handling toolstrips is really a headache. I'm badly in need of it.
