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[^].

I have two datatables which are populating from two different tables of two different databases. I want to get all the records of first datatable which are not in 2nd datatable. I ‘m using the following piece of code.
odr = oDs.Tables(0).Select("Sno = (SELECT SNO FROM " + Convert.ToString(oDataSetChanges.Tables(0)) + ")")
or this one
odr = oDs.Tables(0).Select("Sno NOT IN (SELECT " + Convert.ToString(oDataSetChanges.Tables(0).Columns("SNO")) + " FROM " + Convert.ToString(oDataSetChanges.Tables(0)) + ")")
or I tried the following code as well
oDv1.RowFilter = "Sno NOT IN (SELECT SNO FROM " + Convert.ToString(oDv2.Table) + ")"
where SNO are the primary key columns of both tables but by using all these code I got the same syntax error that is
Message "Syntax error: Missing operand after 'SNO' operator."
Kindly help me in this reagard ASAP
Thanx in advance

I don't think this is possible. The Select() method doesn't have the full power of SQL - it can only define fairly simple filter expressions.
You can set up relations between tables in a DataSet with the Relations property to set up a parent/child table relationship; however, I don't think you'll be able to do this in this case - I don't think it'll help.
I'd recommend - assuming that your data is coming from at least one SQL Server - setting up a link between the two servers (so that server A can see the table on server B) and performing the difference operation in a stored procedure. You can then use the full power of SQL.

hi mike
thanx for ur reply. i used ur opinion i.e linked both the sql servers via enterprise manager now tell me plz how much it will take effect on the execution performance with respect to time than that of disconnected datasets.

SQL Server uses OLE DB internally to access and manipulate tables of data. It's optimised for manipulating data sets.
As long as the connection between the two servers is at least as fast as the connection between the client and the two servers, you shouldn't see any difference.
Indeed it might even be quicker than two datasets, because SQL Server will tend to fetch rows from the linked database and its local database asynchronously, whereas you typically fill your local datasets synchronously, waiting for the first to complete before asking for the second. (I believe you could do this yourself by using BeginInvoke to perform both operations on the thread pool, then wait for both IAsyncResult.AsyncWaitHandles to be signalled).
Your experience may vary and, as always with performance, you should measure it rather than guessing. Query Analyzer can show you the query execution plan and the time taken to execute the query.
If the link between the servers is slow (perhaps they're located far apart, geographically?) you could consider replication instead.

|

thnx for replying
yes in my case the servers are far apart like for example one in US n other in SingaPore so can u tell me how i use replication as i have no idea of replication. i'll b very thankful to u

I could regurgitate a whole load of documentation here, but I won't: I'll just direct you to SQL Server Books Online[^] - note, this link is to a download, not online documentation.
In the Contents tab, go to Replication.
Snippet:
When to Use Replication
With organizations supporting diverse hardware and software applications in distributed environments, it becomes necessary to store data redundantly. Moreover, different applications have different needs for autonomy and data consistency.
Replication is a solution for a distributed data environment when you need to:- Copy and distribute data to one or more sites.
- Distribute copies of data on a scheduled basis.
- Distribute data changes to other servers.
- Allow multiple users and sites to make changes then merge the data modifications together, potentially identifying and resolving conflicts.
- Build data applications that need to be used in online and offline environments.
- Build Web applications where users can browse large volumes of data.
- Optionally make changes at subscribing sites that are transparently under transactional control of the Publisher.
If you always want the latest data available to your client, and cannot stand any stale data, stick with linked servers. Otherwise replication should produce less traffic between servers.

Not sure about you guys but I often need to paste the output of console apps into emails, documents, and the like so what I normally do is:
dir /s > test.txt
Then open up "test.txt" and then copy and paste the contents to wherever I need it and then delete "test.txt" now this is a pain and I thought there has to be a better way. So I wrote a utility in VB.Net to solve the problem. I would have written this as an article but the .NET Framework has made this so simple the article would be too short 
1. Create a new console application
2. Add a Reference to System.Windows.Forms
3. Paste this code into the Main function
Dim strInput As String
strInput = Console.In.ReadToEnd()
Windows.Forms.Clipboard.SetDataObject(strInput, True)
4. Compile and put the resulting .exe in your path
Now all you need to do is:
dir /s | YourProgramName.exe
Then go into your email, document, etc. and paste... the program has captured the console output and put it into the clipboard. Hope you guys find this helpful.

I finishing up some code I wrote for a multi server chat that uses TCP/IP and Telnet, and I was wondering if there was any interest for it on this site. Its writen in VB.net and its completely convertable into a MUD, data pipe, or FTP system. If there is enough interest I will post all of the source. I hope you guys like class files, cause darn near the whole thing is made up of em

Maybe you should submit it as an article. I'd certainly be interested in reading it.
