Is there anyway to get to know the table primary field name?
The information I have is table name and record id of this table, but to form a SQL statement to select those records, I need to know the table primary field. Is there anyway I can get it?

Take a look at ADOX (Active Data Object Extensions, IIRC)

Dear VB.NET Forum,
I have just started my first programming exercise in VB.NET. When I try to run the project an error code come up indicating that Sub Main is missing in my project. Kindly explain to me what this 'Sub Main' is for and how should I include it in my project.

Ok, first of all, what project are you running? Is it a Window application? Or is it a console Application? Where is your entry point into the app?

Hello Nick
I am running a Windows Application Project. I have not programmed in VB before, and what I have is the latest VB.NET software loaded on my machine. I am trying to teach myself VB.NET, but too bad the starting point seems to be quite difficult. Can I teach myself the basics of VB using VB.NET?

Don't worry about it. VB.Net is quite easy once you get the hang of it 
OK, regarding your question. In VB.Net, there are 2 possible points of entry in an application, A windows form, or a Sub Main. To set either one, go to your Solution Explorer, Right-click on your Project and choose properties. Look for the "Startup Object" properties and it's corresponding Combobox, which will list any "Sub Main" and windows form in your application. Choose any one to have your program "start" from that point.

Hello,
I am unable to get my combobox to load.
I have the user iner or scan a number into the textbox.
This calls a procedure and walla.....My CB should populate
but no. Can someone give me some suggestions from my code?
I get an object required error right here 
Also, how can I get it to accept a scan instead of a user
hitting enter after entering the data?
Thank you very much.

Hi all,
I have been in the IT industry for nearly 10 yrs now, and have no programming skills at all. Finally decided to bite the bullet and throw myself into it head first. However, I haven't tried programming since I was 18, some 12 years ago, and my current financial situation means purchasing books, etc. is out of the question. So, if there are any nice people out there who think they can help me, please get in contact.. Any help would be greatly appreciated, however little....
Cheers everyone..

I got this BASIC code from an old book, I am converting this to c, could somebody tell me what is "On NTY GoTo 610, 620, 680, 690" function is? I know that is to go to line 610,620,680,690. but what are the conditions for that?
what about " !" in here?, In c if it is "!=" that is not equal to, but what about here? It canot be factorial number.
NTY = ITYPE(I): KP = 4 * (I - 1) + 1
600 On NTY GoTo 610, 620, 680, 690
610 R = ELEM(KP): GoTo 660
620 REY = ELEM(KP + 1) * Abs(Q(I)): If REY < 1! Then REY = 1!
630 If REY < 2000 ! Then GoTo 640 Else GoTo 650
640 R = ELEM(KP) * 64 ! / REY: GoTo 660
650 R = ELEM(KP) * 1.325 / (Log(ELEM(KP + 2) + 5.74 / REY ^ 0.9)) ^ 2
660 DH = DH + S(J) * R * Q(I) * Abs(Q(I)) ^ EN
670 HDQ=HDQ+EX*R*ABS(Q(I))^EN GOTO 710
680 DH = DH + S(J) * ELEM(KP): GoTo 710
690 DH = DH - S(J) * E(LEM(KP) + Q(I) * (ELEM(KP + 1) + Q(I) * (ELEM(KP + 2) + Q(I) * ELEM(KP + 3))))
thanks in advance

as I recall
On NTY GoTo 610, 620, 680, 690 statement tests NTY and jumps to 610 if NTY=1 , 620 if NTY=2 etc.
in VB6 ! meens that the number is single.
but in GWBasic I used to see it if I write a huge number (the editor adds it)

I am very new to Visual Basic 6, so forgive me if this is not the appropriate forum for this question.
I am building a form that has a text box that will hold hexadecimal data. I want to be able to take this data and display it seperate boxes of 2 characters. I know this can be done using Left(textName, 2) and also Mid(textName, 3, 2) but I can't seem to make it work.
Example: Text Box with this data: 22AB3F3202
That would yield text boxes with this: 22 AB 3F 32 02
I hope I made what I need clear and that someone can help me.
Thank you!

While there are a number of different ways you can do this, here is just a quick example:
Dim str, buff As String
str = Me.TextBox1.Text
Do While Len(str)
buff = Left(str, 2)
ListBox1.AddItem (buff)
str = Right(str, Len(str) - 2)
Loop
You can obviously remove the listbox instruction, this is only an example. Hope this helps.

you could cut down with the string , also you could make an array of your textboxes , then you could use something like this :
Vb6:
<font color="blue">Private</font> <font color="blue">Sub</font> Command1_Click() <br> <font color="blue">Dim</font> code(2 To 49) <font color="blue">As</font> <font color="blue">String</font>, x <font color="blue">As</font> <font color="blue">Long</font> <br> <font color="blue">Dim</font> txthx(2 To 49) <font color="blue">As</font> <font color="blue">String</font> <br> <font color="blue">Dim</font> tb <font color="blue">As</font> TextBox <br> <br> <font color="blue">For</font> x = 2 <font color="#0000FF">To</font> 49 <br> <font color="blue">For</font> <font color="blue">Each</font> tb <font color="blue">In</font> <font color="#0000FF">Controls </font><br> <font color="#0000FF">If</font> tb.Name = txthx(x) <font color="#0000FF">Then </font><br> tb.Text = code(x) <br> <font color="blue">End</font> <font color="#0000FF">If </font><br> <font color="blue">Next</font> <br> <font color="blue">Next</font> <br> <br> <font color="blue">End</font> <font color="blue">Sub</font> <br>
that would cut out a lot of code
Vb:
<font color="blue">Public Function</font> TwinsOnWay(<font color="blue">ByVal</font> twins <font color="blue">As String</font>) <font color="blue">As String <br> Select Case</font> twins<br> <font color="blue">Case</font> "Gender" <br> <font color="blue">Return</font> "Two Girls" <br> <font color="blue">End Select <br> End Function</font> <br>
|
|
|
|
|
That looks like it would save a lot of code, but I'm not sure how to use it to get the results I need. Am I correct that this is attached to a command button?

I can't believe I haven't been able to find any way to clear the console
screen in vb.net.
All I want is to clear the console screen just like issuing a cls command
at a command prompt.
Does anyone out there know how this is done?
|
|
|
|
|
You could try P/Invoke'ing the FillConsoleOutputCharacter function. See MSDN Library for details.

|

Thank you!
I found it in the MSDN libraries url is http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b319239
if anyone is interested. A WHOLE lot of work just to clear the console,
I can't believe they didn't include this functionality in the Console
namespace.
Oh well, maybe next time. Thanks again!
|
|
|
|

If it's any consolation (no pun intended), there's no function for this that I can see in the C runtime library either - I was going to look at the implementation if there was one.
In case anyone else wants that article, clickety[^].
