VS 2008 Make MySQL/DataTable Handle Norwegian Characters?

Oct 4, 2009

I'm populating a DataTable from a MySQL-server. One of the columns contains norwegian characters (�, �, �), but they don't display correct in my datatable. I've been searching google for some answer, but I haven't found any. I've never had this problem before. Actually I'm not quite sure exactly where the problem is. It's either in the datatable or in the MySQL .NET-connector as far as I can tell. If I do the same query in the MySQL Query Browser, the characters are shown correctly, so it can't be the server.

DataGridView - Handle Conflict With Constraint In DataTable

Aug 26, 2010

I have a datagridview in which the user can add new rows. The datasource is a datatable who has a unique-constraint for the column "Position". Thus, if the user enters a position already existing, an exception is thrown. To avoid the ugly standard error message, I simply handle the dataerror-event and set e.cancel = true. This works. But if the user presses escape, the row_validated-event is triggered. I use this event to format the rows containing new data by changing the font color to red. Here another exception is thrown (SystemOutOfRange-Exception) telling me that the index xxx has no value. How can I achieve row-formatting for new/modified entries without getting this error?

Here is my code:
''' <summary>
''' Catch exception and cancel illegal action.
''' </summary>
''' <param name="sender"></param>
''' <param name="e"></param>

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

Pure Text Files / Handle Special (german) Characters In .net Vs VB6 Old Files?

Jul 17, 2009

i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".

Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.

But when i write code like
Dim strTest As String
strTest = File.ReadAllText("ae.txt")
Debug.Print(InStr(strTest, "ä"))

i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.

Make The Default Modelbinding Handle Lists?

Jul 9, 2011

How do I make the default modelbinding handle Lists?

Let's say I have a ShoppingCart class, which has a ShoppingCartItem List:

Public Class ShoppingCart
Public Property CouponCode As String
Public Property Items As New List(Of ShoppingCartItem)
End Class

[Code]....

However, when I submit the page, no values are picked up, not even the CouponCode field. The model object is empty. What gives?

Ultimately, my goal is to add/remove items clientside via javascript and then have the modelbinder pick up the changes automatically when the page is submitted.

Update: I was just missing the Property keyword from my model properties declarations. It's too late, and I got to get some sleep. :)

If i had 10 mins per million, that is a long time..

Someone may think this is bruteforce hacking, but I don't see why I should do that? If I want to find a password on 13 characters, it would be: 62^13 = 200028539268669788905472 possibilities... in other words... it would take forever!
