VS 2008 Saving A Time Value In SQL 2005
Mar 22, 2009
In an VB2008 application an email can be saved in a SQL 2005 database. The date, time and subject are saved in SQL. Let's say the receiving time of an email is 12:56:55. After saving the values in SQL a SELECT of the SQL table gives me a time of 13:56:55. From this result I conclude SQL is saving a time value differently. - Is this difference come from the time zone? - Is this difference come from the daylight saving? - Is this difference come from both? How can I easily compare these two values?

When ever I add a new entry into the database, it will do it. When I click save, it will save it. When I go back to edit the entry after it was saved the first time, and I hit save again, I get a concurrency violation? It only does it when I add an entry. If I close the program out and restart it again I can save all day long as long as I don't add a new entry. First of all, dunno where the violation is coming from, but I only have a message box on my catch statement on the save button.
I have added it to the database using the following code 100 times and it has always worked:
Me.shuttlerunsbindingsource.addnew()
My save code is:
Try Me.Validate()
Me.ShuttleRunsBindingSource.EndEdit()
Me.ShuttleRunsTableAdapter.Update(Me.ShuttleRunsDataSet.ShuttleRuns)
[Code] .....
Why after a million times of using this exact same code is it not working? It will save all day long no problem as long as I don't add a new entry. Here is my add
Try ShuttleRunsBindingSource.AddNew()
EmployeeInitialsTextBox.Text = lblUser.Text
Catch ex As Exception
MessageBox.Show("UNABLE TO ADD! " & ex.Message) End Try
The message box for the add code never shows so I can't see that is causing any trouble. I am using VS2010 and a local database, not SQL. I just tried doing it again, I added an entry, I saved it, I got a successful message. I then tried to change something and I got a concurrency violation when I clicked save again. I then tried to delete an entry and it successfully deleted it, but when I went to edit another entry and save I got the violation.

I have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.
My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).
I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.
I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.

Right now the existing VB code I have uses GUID to generate "random" filenames on save.
For instance:
ff8514d389a041649fd8b925a32f2b51.jpg
e1c938560fc1464ab2138065fc4661d3.jpg
Instead I want a date stamp, Time Stamp, and numbered filename:
For instance:
20091015_131644_001.jpg <--(Date_Time_NumberIncrement)
20091015_131551_002.jpg
Or something along those lines. The current code (which saves a jpeg to a random GUID filename) is below:
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.IO

I want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

i want the user to login, and the first thing is, having the text document for that(if theres a safer way to do it, let me know) then it goes to the weekly sales page, but theres also the goals for the sales, which rarely change, but if they do i would like them to be able to change them, then next page is the list of the workers, and if they need to i would like them to be able to add workers. so my question is: is there anyway that maybe i could save both the goals, and the workers in the text document, and when they need to change it/add workers it will save it in the text document and the next time they sign in the changes will be permanent? also is there a way to delete the user once they have been created, other than going into the txt document and deleting it.

I have noticed in a windows-based VB application I am working on when the "Automatically adjust clock for daylight saving changes" is de-selected, the time in the application is off by one hour. Is there anyway to make the application not sensitive to that and just display the date value that is retrieved from the database?

I would like to know if it is possible to make my application be able to save the file as the current date. the idea is to have it where the staff login to the application and the application opens the file with the current day.
This means that in the morning before staff open the program the office staff can put up the information, i.e. like briefing sheet, daily notes. etc

I have a table in SQL Server with a field defined as Varbinary (MAX). In VB I am trying to save an image to the table. The file I'm using is 139kB in size and I get no errors but when I look at the record, the Attachment column where my image stream should be is empty. The rest of the information is saved. I checked the buffer and it grabs the correct size of the file (141475) so I'm very sure it's found and loaded the image.
Could the parameter from the SQL not be passing the binary value to the parameter properly?

Using VS2005. The code below saves a datagrid (datagridview1) to XML file and works well. But if newPat is true then I want to save the extra data in the XML file as well. But it doesn't work for some reason. When newPat is true it just saves the XML file as normal but without the extra row.
It seems this code is not working what so ever. I tried replacing
dr("patientName") = gridrow.Cells("patientName").Value
with
dr("patientName") = "test"
And it didn't work, it still saved the names that were in the grid.
newPat = true
For Each gridrow In DataGridView1.Rows
Dim dr As DataRow

I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.
Dim comp(maxsize) as ccircuits[globally declared]
Const maxsize = 50
