how to SQL Command and fill Result in ComboBox? in visual basic 2010 my DataBase
Dim SqlCon As New SqlClient.SqlConnection("Data Source=DIG-PCDIGSER;Initial Catalog=;Integrated Security=True") Dim ConDatBas As New SqlClient.SqlConnection("Data Source=DIG-PCDIGSER;Initial Catalog=DigSMSystem;Integrated Security=True")
I'd like to, let say "declare" my custom command, and what do I mean by command is something you type in the code, when for example you click a button. Just like Textbox (for example), my custom command sould have "underthings" in it, so just like I can type in Textbox1.Text. And that underthing (in this example, textbox is my custom command and .text is a sub/underthing) I can set if it is a boolean or string etc. I need this for my login program, where that custom command is an username (named username, what you can dim), and then it has sub things, like username1.email (string for e-mail text) and username1.password, username1.ismoderator (boolean, true or false). So an example, in my program I can do like this:
'Username is my custom command, just I don't know how to'define or declare it.'Username has here, to keep it simple, 2 sub things, it is'username.password and username.name Private Sub btn_registrate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_registrate.Click'When the button called registrate (make new username) is clicked Dim username1 As Username'(I don't know if it must be dim blabla as NEW or without new with'my custom command)username1.name = Textbox1.Text 'Textbox for username username1.password = Textbox2.Text 'Textbox for password
When I click a Button I what to save all the textBox's text on my form. The code I have Is Below.
In My settings Have I got to List each textBox. Like TextBox1, TextBox2, TextBox3. ect..
IE: My.setting. textBox1 = TextBox1.text (In settings TextBox1: have it as string: User)
IE: My.setting. textBox2 = TextBox2.text (In settings TextBox2: have it as string: User)
Or can I have just one TextBox In my settings, that save's all the TextBox's 1 to 8 on my form

The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

I'd like to make a textbox that accepts only numbers, but not integer, but rather double.I've read here about e.Handled = Not Char.IsDigit(e.KeyChar) and it works, but again, it can be used only for integer, since it declines decimal point.Another thing I've read here is If Not Double.TryParse(TextBox2.Text, value) Then .... and it would work fine, except that it allows only decimal comma instead of point.

I am looking for special tag codes that can be used to define certain words in a diffierent font format, like bold, italic, etc. I have a special command that accepts initial tag and end tag to these special words.So, these tags must be interpreted by textbox in VB to turn some words in bold, for instance, and change back to normal font after those words.
The command I have is:
textbox.text = data_base_name.FieldByName("field_name").HighlightedString(index as long, start_tag as string, end_tag as string)
The effect in the textbox should be like this:
Example of special word in bold.Any one knows about the existance of these special tag codes? I wonder if there is something like old DOS Codes, or ANSI, that can be recognized in VB textboxes.
