Using item still places SpcInstr in the text of the label. I am trying to get the value from the column named "SpcInstr". Any other suggestions?

Add a reference to the dll. In the solution explorer drag that to your toolbox.

I am having a problem with a user control that I created for a windows form using VB.NET. The problem is that when I click the tab key or minimized the form, the control moves to the right side of the form. I really appreciate if anyone gives me any suggestion to stop moving that control from clicking tab key or minimize the form.
Thanx in advance.
Thanx

This control should only move if you have code to move it. Do you have something setup to change the layout of your controls?? I would also check the designer generated code that creates the controls for you to see if there is anything in there that setups up the wrong docking and anchor properties.
If you have any control containers on your form, make sure that the control that is moving is a member of the correct container.

I have a multiline textbox on a form that a user can type information into. When they click update it writes the contents to a SQL table. If the user types a quote in the textbox the update fails. How do I update when there are quote characters?
Thanks for any help on the matter

That is because you don't handle the string values in the query correctly. You have to escape some characters when you put a string value in an SQL query.
For MSSQL and Access you escape the apostrophe by replacing them with double apostrophes.
For MySQL you escape backslashes by doubling them, and apostrophes by putting a backslash in front of them.

Thanks, I remembered reading that awhile back but had fogotten it.

Or you use parameterized queries (best practice!) and you won't have to worry about escaping anything yourself.

I have created a student database in Ms-Access.
the records are stored through the FORM(VB.NET).the form has different buttons for selecting the education forex-Primary,secondary & higher secondary etc.
now what i want is once a record is saved.the value in the name field(that is the name of the student) should be listed in the listbox depending on the button clicked (as mentioned above)

How did you fill the ListBox in the first place? All you'd have to do is call that code again.

You don't. That number will only be generated when the record is actually written back to the database.
IF you went a "checked-out" a blank record in the database, you'd get the number generated, but you would be forced to "use or lose" the number.

When I regsvr32 this dll, it shows me that the dll no need to registry.
But I cannot add it to reference.
The author tells me that it can import to VB.NET directly but no need add to reference and registry.
Any one can tell me the method? Thanks.

That's because it's not a COM .DLL.

You have to import the functions from the .DLL to use them. THis is done using the Declare[^] statement in VB.NET.

Hello, I am expereinced VB6 developer, have not coded for 3 years however. I need to design a class model for a Vb.NET application. I understand OO, I am however unclear on the implementation of Class collections in VB.NET. I read somewhere that class collections are now legacy. If so how do I enum and iterate though classes? All the topics I find on this involve a class collection still? Did I just read wrong about Class Collections being legacy?
On a similar note, are there any topic, threads on bind classes of data to the controls that show them on screen? In VB6 I did this long hand by iterating through the classes. I used the index property to do this. Will the new Handles event work with updating class collections?
Sorry if this is unclear.

There are various collection classes you could use. Which one is up to your requirements.

 Hi I have managed to extract the following from some html source and display it in a Rich text Box.
What I would like to do now is either dsiplay just the numbers in a text box (in the above case) 3 5 8 10 44 3 & 5 or download the gifs and display then.
I can't hard code the numbers/ gifs in as they will change on a regular basis
Any help or advice would be most appreciated
Thanks

Could you just get the position of 'alt="' in each line, add 5 to get the position of the number you want, then just grab the following characters one-by-one until you hit another quote character?

You could either do it with simple String manipulation or with RegEx. If you're not familiar with Regular Expressions, it's can be a bit confusing to start with.

I have now done this with another regex command as suggested in previous posts.
Many Thanks for the advice

I'm using VB.Net 2003.
I want to connect my client app to a SQL Server over the internet.
How do I send my connection request through the local proxy server?
The setup:
SQL Server --> Firewall -->>>>Internet<<<<-- Proxy Server <-- Client App
The neccesary port forwarding has already been set up.
It's not a HTTP request that I'm looking for.
|

That depends entirely on your Proxy server, what it supports, and what it requires you to do. You're first step would be to dig up the documentation on your Proxy server. You might be looking for Socks support, if nothing else.

The documentation merely specifies the setup and installation - nothing as technical as how to formulated a SQL request.
I think it may be neccesary to wrap the SQL within a HTTP request but I have absolutely no idea on how to do that. If anyone maybe knows about a site with alot of info on HTTP requests it could help me a great deal.
