[2005] DateTime Bindings DateTimePickers?
Jan 26, 2009
I want to update the date and time from two separate pickers to my table.My 2 DTPers are bound to a dataset.One is in the Short Format, the other is Time.I have several other bound controls, and I just do a .Update to update my table. I tried just updating the row:
Me.DsTradeShow1.Tables("Tradeshow_Details").Rows(0).Item("Show_Date") = CDate(Me.DateTimePicker15.Text & " " & Me.DateTimePicker16.Text)
but it throws an exception when I do my save.

I'm making a form with an overview of orders from our clients. I have inserted 2 datetimepickers so the users can choose a period.
To know how many cols I need in my grid, I need to know how many months there are between the 2 datetimepickers. But that seems to be the problem. How do I get the number of months starting from one datetimepicker untill another.

I have four datetimepickers. (datefrom, dateto, timefrom, timeto) 2 that allow the user to select a date from and a date to (at the minute these work okay) and 2 that allow the user to select a time on that day that they have previously specified (at the minute these don't work)
What I would like is to allow the user to be able to select any time between 01 Jan 2000 and now.The timefrom time cannot be higher than the timeto time if the 2 date selects are equal.The timeto time cannot be higher than the current time if the dateto selected is the current day.There's also an interval of 15 minutes. So, if the days are the same, the time cannot be within 14 minutes or less of each other
Also, something that happens is, when the code executes. I change the timefrom so it equals 00:00 and the timeto so it equals 00:15. When I press the down arrow the change the timeto to 00:14 the timefrom changes to 23:59.

How do I achieve the same in VB.NET which is so easily done in SQL Server.
Select Case(GetDate() as VarBinary(8)) --Gives the Current Time in Hex
How can I create the same string in VB.NET so that I can compare in SQL Server as such -
Select Case When GetDate()=Cast(0X00009F5E00D8DF7C As DateTime) Then 'True' Else 'False' End -- 0X00009F5E00D8DF7C Will be the value I get in VB.NET When I convert it Date.Now() To Hex

I'm adding a DateTime DataColumn to a DataTable like this:
Dim colDate As DataColumn = New DataColumn("Date")
colDate.DataType = System.Type.GetType("System.DateTime")
dt.Columns.Add(colDate)
Then when I try to add it to my datatable, if the value is Nothing I get an error saying string was not recognized as a valid DateTime. I'm having trouble getting this to work.

Weird problem that just started, I am using an OleDbCommnad to create a dataadapter then fill a table everything from a .csv file, works fine except no dates are coming over? I added a datagrid view to my project just to see and any column that should have a date value is empty. I confirmed that the column is of System.DateTime value so I am at a complete loss?

Previously I converted a string with year, month, day and minutes/seconds using
CDateTime(conYear, conMonth, conDay, conHour, conMinute, conSecond)
This code will no longer work in VB.net and I cannot figure out how to do this with 2005 VS. The string originally is something like "20100310142715" and should be broken down into year, month, day, hour, minute, second.

Although a few people around here have said that Dates are not a huge deal that they're simply data, I always seem to get stuck on them, and my current issue is no exception. I am trying to save/retrieve data between my Access 2003 data and my VB2005 form. I have tried any number of combinations (even the forbidden Value.ToString, and having the Data Type in Access as string, and although it worked fine for saving the data, it doesn't work for loading it back into the form.). Here's my code for saving the data to the database:

I have a load sub with a few declarations isorry for thn it as so: [code] But when the TimeFrom_dtp.ValueChanged code is executed, the Time From_dtp.Value isn't correct as it hasn't been set yet. If I change it round so the TimeTo_dtp.Value is set first then that doesn't work because the TimeFrom_dtp hasn't been set yet? How can I get it so that the ValueChanged code isn't triggered until I've set all the values of my datetimepickers?

I am writing a program to analyze error logs from an existing application, and I want to consider only lines that have a Date/time stamp at the beginning of each line.( in the format "03/13/08 08:03:58") I am extracting this as a string and want to evaluate it to make sure it is a valid date so I am using "IsDate(Mid$(TextArray(i), 1, 18))". The problem is that IsDate evaluates False even when the string I am passing should be valid (eg. 03/13/08 08:36:59).

I have a list of sites that I need to update their bindings from the current IP address listed to another one, how can I possibly do that using VB.NET? I will have to do this often and I don't want to manually update that every time.

I'll try to make this simple, using VB.Net on Windows Vista:How do you change key bindings programatically?I'm thinking it has to do with the registry so if it does just give me the registry key names(i know how to change the registry already)If it helps, the reason I want to do this is to change the Windows media center button so that it opens my program rather than WMC.

I'm trying to set up an installer to register a web site. Currently, I've got it creating an Application Pool and Web Site under Windows Server 2003. Unfortunately, whenever I try to modify the ServerBindings property to set the IP Address, it throws an exception at me. I first tried this because the documentation here told me to [URL]. I'm currently using VB.NET, but C# answers are okay too as I need to switch it over to using C# anyway.

Difference between Early and Late Bindings.
Example of Late Binding:
If
sender IsNot Nothing AndAlso TypeOf sender Is Values Then
receiveobj = CType(sender, System.Object)
a1 = CType(receiveobj.a1, Int32)
End If
How do I change this into the prefered Early Binding?

I have a custom class and my dependency properties won't work with bindings unless I declare the class as a static resource.
My xaml:

<sdk:Frame.ContentLoader>
<myLibrary:RegionNavigationContentLoader
RegionManager="{Binding RegionManager}"

This is the form I'm having problems with. As you can see I've created a tab interface which is working. There are five text boxes on it which are binded to the Staff table in the database. When the tab is changed, the binding is changed to a new field. However, unfortunately, when a new record is selected, the data bindings do not update, and instead, the first record is always being used. We suspect the problem may be coming from the fact that there is code to unbind from the text box and rebind it again. This is the code I'm talking about...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1
txtBox1.Visible = True
txtBox2.Visible = True

I have a GridView and some textboxes, etc whose BindingSource is a list of business objects.
Problem comes when my business objects are updated programmatically. My objects implement INotifyPropertyChanged, and I raise the PropertyChanged event when the object is updated. When the object changed happens to be the selected row in the GridView.
I get the following exception: System.InvalidOperationException
DataBinding cannot find a row in the list that is suitable for all bindings.
How can I solve this?

I am having difficulty getting some form control property bindings to work correctly. Below is the code I am using-
[Code]...
The ZedGraphControl is just a GraphPane, and the TolSelectBtn is just a button. Problem is, the ZedGraph control binding works properly, but the binding to the button does not (both controls' Visible properties are set to False in the design window). Can a ToolStripMenuItem only handle one data binding? Or is there something else I should be looking for?

I have a project that I used the 'Connect to Database' tool to set all the bindings and table adapters, etc. Currently the database is housed in the same directory as the exe. I was asked if I could have the database location be a dynamic value. My question is when you set up a project to work with a database using the 'Connect to Database' tool, how can you change its location?
I found this setting:
ASRDBConnectionString
But its read only.
Within that setting is text that says: DataDirectory
So thought that might be a variable to change somewhere....but can't find it.

I have a form with a datagridview, 2 datetimepicker(dtp) controls, combobox, textbox, 3 buttons and a bindingsource. All my controls are bound to the datasource and seem to work fine when the form loads. One of my datetimepicker controls losses the bindings when I add a new row to the datagridview and save the changes. I validate the date entered in this dtp.
