View 2 RepliesConnect Webapp VB/LINQ To A MySQL Database Server On A Linux?
Jul 7, 2009I have a programmer who is using VB and LINQ; and I have a MySQL database that is running on a linux server. My programmer tells me that:he cannot connect to the MySQL database via LINQ if he was able to connect then it would require all sorts of rewriting I don't know anything about LINQ but I thought it was an ORM. As such, any DB server that is supported should work just fine? Right? OK, so maybe it's not an ORM... maybe it should generically connect to ODBC and render similar results?

How To Alias A Namespace / Class
Nov 13, 2011I'm writing custom code in VS2005 Reports (SSRS / Report Builder). The code is working fine, but I have to make absolute references to assembly classes. For instance:For Each m As System.Text.RegularExpressions.Match In ...Is there any way to alias the reference to System.Text.RegularExpressions.Match, so that I can reuse it in a concise manner?

.net - Alias In Function Declaration Overloaded?
Feb 24, 2009I have some VB6 code that I am converting to VB.net and came across this section
Declare Function TmSendByLen Lib "tmctl.dll" Alias "TmSendByLength"(ByVal id As Integer, ByRef msg As Any, ByVal blen As Integer) As Integer
'snip'
[code]....
I have not come across the Alias term before but I can guess what it does. What I am unsure of is the reasoning behind overloading the alias. If that is what is happening.I need to create overloads for the TmSendByLen function as the 'As Any' is not supported in VB.net so I am not sure if I should just remove the alias or if I should leave it in place.

View 1 RepliesC#/.NET: How To Improve Anti-alias Quality
Aug 16, 2011In Reporting Service, I need to have a vertical, starting at bottom, bottom-to-top, horizontally middle aligned text.The only way to do this is to create an image in code, and set this image into the title column.See the code below.Basically, it works fine, just that the anti-alias quality is pretty crappy.Is there anything I can do to improve it ?The vertical text is somehow pale, and not full black, and also there is smearing all around the text, in the background color.As well as it appears bolder than the text on the left, but both have format arial, size 8, bold I've tried all other values of System.Drawing.Text.TextRenderingHint.*, as well as no anti-alias at all but the current one seems to be the least crappy.I've also tried to change the image format, to no avail:
Function LoadImage2(ByVal sImageText As String, ByVal sImageTextMax As String) As System.Drawing.Image
sImageTextMax = sImageTextMax.PadRight(15)
Dim iFontSize As Integer = 8 '//Change this as needed

Declarative - Enforce Type Alias In .NET?
Apr 6, 2012How might one go about aliasing a type in VB.NET or C# such that when the alias is used as an argument type in a function, accidentally using the not aliased type is an error?
i.e.
Imports AccessSpecifier = System.String
Module Accessors
Delegate Function IoOper(ByRef strm As System.IO.Stream) As Action
[code]....
Overall, I'm wanting the IDE to force me to know what I'm doing if I'm throwing Ints around to mean Flags, or States and Strings around to mean Names, Propertys and Records.

View 8 RepliesShow A Query Alias In Column?
Aug 13, 2009I am using a databound datagridview control. I created a custom query to fill the grid with which includes joins and using alias names in the sql query for the joined fields. Here is the query I am using:
SELECT Events.[Date], Events.[Time], Contacts.LastName AS Lastname, Contacts.FirstName AS Firstname
FROM (Events INNER JOIN
Contacts ON Events.ContactID = Contacts.ContactID)
The datagrid views fine using the columns that are in the events table. I want to be able to view the aliased columns from the contacts table in the datagridview as well.
How can I display the joined columns in the datagridview? Maybe there is a better way to do this? Maybe this is not enough information for a resolution.

Sep 30, 2011We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).
