Good Freeware That Will Correct Once Translated From C#
Feb 2, 2012
I've used Teleflex, developerfusion, and SharpDeveloper, and all these, to convert C# to VB, but as most know, there are always errors, and modules left out, and such.Does anybody know of a good VB editor, preferably freeware, and can handle translated VB and offer suggestions to correct it for you? Visual Studio underlines things and offers suggestions on some things, but other things it just underlines and leaves you to the guesswork, which doesn't help a non-coder like me.

I have completed a vb and sql desktop program. This program is more intended for personal use. However, if I wanted to redistribute the program as freeware, what kind of stipulations do I have to place or what kind of changes do I have to make for someone else's use? I have made web programs with SQL, but never made a desktop program with SQL until now. Currently, I have no problems running the program on my end of the computer. But running the program on another computer end is the question?

We use LINQ to SQL extensively, and one of the biggest performance pitfalls we've run into is situations where a query can't be converted to SQL, and so an entire database table gets loaded into memory and the query performed by .NET. For example, this query
Dim Foo = (From c in Db.Contacts Select c Where c.ContactID=MyContactID)
translates to a simple SQL query, whereas
Dim Foo = (From c in Db.Contacts Select c Where c.ContactID=SafeInt(MyContactID))
doesn't because SafeInt is our own function and doesn't have a SQL equivalent; so the whole contacts table gets loaded into memory and searched by LINQ to objects, which is vastly slower. With a little experience, we've gotten better at avoiding this kind of situation. But it's not always obvious, and this is the sort of problem that's often not revealed until you're working with a lot of data and things start to slow down. Is there a straightforward way to see - whether in Visual Studio or some other way - how LINQ queries will be handled, other than trial and error?

I've spent a whole day on this already without figuring it out. I'm hoping somebody can help me translate the following MySQL query to work for SQL Server 2005:
SELECT MAX ( messages.date ) AS maxdate,
topics.id AS topicid, topics.*, users.*
FROM messages, topics, users WHERE messages.topic_id
= topics.id AND topics.user_id = users.id AND
topics.forum_id = " . $forumid . " GROUP BY
messages.topic_id ORDER BY maxdate DESC
$forumid is a QueryString value defined in the following VB.NET code-behind code:
forumName.Text = "<a href='ViewForum.aspx?forumid=" & row.id & "'>" & row.name & "</a>"

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

I realize that this would mean a third-party component and I've looked at a few. Does anyone use/know of a component that they would recommend to get reliable, quality Word to PDF conversion via a VB.NET application?
Anyone know of any cheaper options that will do a good job? I tried a couple of cheaper RTF to PDF convertors, saving the Word doc as RTF via the app but the PDF they output lost formatting on Word tabs, table of contents, page numbers, etc. Not good enough.
Otherwise, I will have to tell the app users they will need to convert the Word doc to PDF themselves (unless they have Word 2007 and pdf add-in which I can probably offer as an option).

In my VB6 project I had eight list boxes in an array. I was able to create a command to move to the next listbox by adding one to the index. I was able to move to the next selected item in the listbox with a command also.All the data in my arrayed listboxes: I was wondering if I could put into a ListView with multiple columns in VB2008 (each column would have the items from the listboxes mentioned before).
If they were in a ListView, would I be able to work in each column by moving to the next item with a command like I did before, and then move to the next column of items with a separate command?
I was thinking it would be easier to do that than array all those listboxes again.

I have a little problem with checking if a sql connection is good.
Attached here i have a simple vb.net program that should check if the sql connection to the sql server is good. If i just run it once it works very well. But if i use it in a timer and check the connection to the sql server every 10sec it will only tell me that the connection is good (V=0).
I have tested the code with turning of the sql server service.
Dim connect As String = "Server=192.168.1.2;Database=Test;User ID=sa;Password=12345;Trusted_Connection=False"
Dim sqlconnection As New System.Data.SqlClient.SqlConnection(connect)

I'm looking for something relatively simple - just a monthly calender view where text can be placed on each individual day - just like a calender on a fridge (with a highlight for the current day). Slap it on a form or UC, set up a few properties and all done. I don't even need any clicking events - just a display.
The controls I've seen for sale are much more than what I need and creating my own, while an option, is something I'd rather not have to spend time on.
