Update .xls File On Server?
Aug 28, 2010
my application reads from an .xls file I put on google sites. The problem comes when the application modifies a cell and tryes to save the file on the site, actually it does nothing since to read something from the site is easy, while trying to save something requires a connection with username and password.
So, how can I pass the username and the password to the application? and even most important,can I encrypt it so that the person who uses my application could not see the real trafic details with a http sniffer?Right now I am using this code:
Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet
[code].....

I make changes on my program very often so after I change something in application I have to go from PC to PC and copy paste new .exe file or .dll. I have more than 100 pc. I was thinking on this way but I do not know how I can make it; I want run application in the server, if got any update files server should update to rest of the pc which are online. In this case I do not need to walk around and copy-paste files every time I make any change in application.

I'm making a game in Gamemaker and i'm using VS2010 to create a launcher for it. The launcher works like the Minecraft launcher:
it has to check a file from my server, then compare it to the local file, and if they aren't the same, the launcher has to re-download the game.exe from the server.
This all has to happen when i click play. To make the game start i use
Process.Start(My.Computer.FileSystem.CurrentDirectory & "\game.exe") i've put the game in the solution explorer.
put 'copy to output directory' to 'copy always'. i appareantly had to do that according to a tutorial to launch game.exe. Now, as i've said, i'm quitte new to VS 2010.

I have a datagrid which is binding in my MS SQL database. I've created a two button: Import Data (this button is used to import my table from access database then display it to my datagrid) and Update button (this button is used to save/update my sql server through datagridview). When i clicked the Import Data button, it successfully import my table from access in my datagrid but the problem is, when i clicked the Update Data button an error message occur. I found the error in this code (da.UpdateCommand = cmb.GetUpdateCommand) saying "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information"
Here is the part of the sourcecode:
Imports System.Windows.Forms
Imports System.Data.SqlClient

I have a DataGridView that displays data from a SQL Server database. It allows the user to edit the data and save it back to the database. The way that data gets saved back to the database is something like this:
Dim da As New SqlDataAdapter
Dim cmdBuilder As New SqlCommandBuilder(da)
da.SelectCommand = New SqlCommand(sql, conn)
da.InsertCommand = cmdBuilder.GetInsertCommand
da.UpdateCommand = cmdBuilder.GetUpdateCommand
Dim cb As SqlCommandBuilder = New SqlCommandBuilder(da)
da.Update(dt)
This works fine when I'm saving to ordinary tables. However I also want to save to a view that has an instead of trigger that fires on insert, update and delete. When I try to use the above with this view I get the error:
"Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information."
How can I save to this view? I don't want to save directly to the underlying table because I want the trigger to fire.
I also tried manually generating the InsertCommand and UpdateCommand, but got the same error. It turned out I got the commands wrong when I manually generated them. Once I fixed that it worked fine - my view gets updated and the trigger fires as expected. I guess that you just can't autogenerate the commands for a view with SqlCommandBuilder.

I know how to insert a new row into a table that has a binary column. But is there any way to update the binary column once that row has been added? So far an exhaustive google search has turned up nothing. Get the current row that I wish to update delete the row that I wish to update Create a new row with the information from the row I wish to update plus the new binary It just doesnt seem very elegant, and I was hoping I could do the same thing with an update statement. Here is the updated code I am using now for reference

I am using Visual Studio 2008 for creating a Winforms app. I have connected a database to it called XStats. There is one table in it called XGames and in that table 2 fields, XIndex (the primary key field) and GameNumber. Using the following code I can add records to the database, the data is taken from a text box, but once added I cannot view them unless I shut down the app and restart it.
con.ConnectionString = connectionString
con.Open()
Dim cmd As New SqlCommand
[Code]....
The existing records in the database are displayed on the form in detailed view via a binding navigator. How can I make it so that I can view all the records in the database, even those that are added during the current session. As will be obvious, this is my first attempt at creating and using a database with a win forms app,

I'm working with Windows Forms - VB.NET.Here's what I have:
A ListView with checkboxes set to True
A Button (triggers the update)
A database table with similar fields as the ListView
What I want to happen:when the user clicks the Button, all items on the ListView with checkbox checked will be updated.My progress:I've already collected the ID of the checked items and stored them in an array. I'll be using this to update the database table.I don't know how to put them in the SqlCommand.Parameters Also, I don't know the update command for such scenario (where in/exist (@parameters))

I fill table data into dataset using Adapter. How to update dataset changes back to Microsoft SQL Server Table. I refer to the following URL, the solution is working fine, it makes use of the adapter.UPDATE to get table updated with changes made to dataset. [URL]
Sample Code:
cmdBuilder = New SqlCommandBuilder(adapter)
changes = ds.GetChanges()
If changes IsNot Nothing Then
adapter.Update(changes)
End If
I would like to know is there any other alternatives besides the one I have mentioned above. Can the alternative supports scenarios such as update existing record (probably based on primary key or defined conditions), insert new record as well delete existing record.
