In a Windows Form on Visual Basic, I have a DateTime Picker for a user to select a time and date from.I'm inserting this value via a parameterized query into an Access Database. However, as I'm running the form, I keep getting the error Data type mismatch in criteria expression.If I remove the parameter from the Insert command, the field enters fine. But when I put it back in, it doesn't work.[code]
View 2 RepliesI am working on Search of records from Database between range of two dates. I implemented it with two textboxes for StartDate and EndDate and it is working fine.Now i want to attach Calender to the textboxes so that user may not have to type the dates instead user may just select the Startdate and Enddate from two Calenders.I tried with adding two DateTimePicker and used following code:[code]I have two queries:
1) DateTimePicker desplays date and time in the Textbox, I want that only Date is displayed in the Textbox.
2) How i can attach DateTimePicker directly to Texbox so that on runtime when i select a date from DateTimePicker it should immediately display in Textbox.
This is quite a pickle... I am using interop to read and write in excel but the project is not reading the excel correctly,!

View 2 RepliesI have a datetimepicker on my form. When I click the down arrow, it goes down correctly. When I select a date, it stays down. In order for it to roll up, I have to change my focus to a different area.Is there anyway to make it rollup when a day is clicked? It feels awkward the way it is now.

Implementing BindingNavigatorAddNewItem executes above line correctly. I don't want this because the bindingnavigator items are active. Coding me.gatepassbindingsource.addnew(), I can make my bindingnavigator items inactive/disabled while adding record.
I have a Datetime Picker on a form.
When I use dtArrival.value for instance, it gives me the date in the format "24/04/2010 10:54 PM"
Is there a way that I can grab the value in the format "YY/MM/DD" e.g the value would return "10/04/24"?
Also whats the easiest way to calculate the number of days between two datetime pickers on the same form? I've tried to do it and it's just a mess.
I have a bit of code that jumps around a few domains and adds a user to each of them. This follow is a piece of code I had to write to get around the issue of the .add and .invoke being ran asynchronously and occasionally causing errors.
It connects to the domain in question, passing a "CN" from the code in as a search filter but receives a COMException which is normally a LDAP sting config issue. The connection string in this is fine so I am not sure why it is having such a hard time.

View 4 RepliesI'm using VB Express 2008 and MS SQL Express 2008. I have a couple of tables in my SQL database and among them are some log tables that track changes in the data entries of the substantive tables and fields I have. I have one log table fore each of the datatypes that appear in my substantive tables.
For example any change to any field in a substantive table where the field is of a bit type will be logged to the BitTypeLogTable. All of my log files are structured essentially the same. For example the structure for my BitTypeLogTable looks like this:
The other logs are identical except that the OrigValue and NewValue fields have different datatypes according to the datatype they are intended to track. For example the datatypes for those fields in the DatetimeTypeLog is datetime and in the MoneyTypeLog is money.
Each of the substantive tables in my database has three triggers which cause entries to be made to the log tables when the substantive fields are changed. For example, one of the UpdateTriggers looks like the following:

View 3 RepliesI would like to capture a start and end time in format hh:mm.Instantly I thought a datetimepicker would be the most suitable component (see code below)[code]Now I'm unable to find a datetimepicker solution to allow settings of intervals like in the numericupdown control and unable to even set a mindate/maxdate in time format. Does anyone have a solution for these requests? I then thought about using a numericupdown control to capture hh:mm time but I could not find a way of doing this in ONE control rather than two whichwould involve code to ensure only valid hours/min values could be selected i.e. 0 - 23 and 00-59 and other date to string conversion/validation.For such a commonly recorded element I'm surprised to find little in the way of solutions other than third party controls.Does anyone have ideas for a way forward for a control to capture time as hh:mm with interval controls for hours and minutes?

View 1 RepliesI'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?
