Wow. I was reading this stuff about how great VB .NET is for Game programmign and it says it supports Multithreading. Hmmm. Someone please tell me what this is?
Thanks

Haven't you done any courses in Computer Science. I sure threads were one of the subjects covered. Anyways...
An Application that is running is usually refered as a process. Within that process, or any process for that matter, are pieces of related codes, or Threads. Thus, a process is made up of one to many pieces of thread.
Now, in VB6, multithreading is not supported since your code gets executed step by step. A thread will have to wait for another thread to finish before it can execute. This can lead to your resources being wasted. An example of this is a thread that is writing to disk. When this thread is executing, the CPU is idle when it could be doing something.
The concept of multithreading is that the CPU should always be doing something, to fully utilize it. VB.Net allows you to execute more than one thread at the same time, thus fully utilizing your app.
For more imformation, try buying a Comp Sci book. I'm sure their explanation is much, much better.;P

Hi all,
I have been roaming aroung with ASP/html/JSCripts for a while in the office. And a sudden boom, 'SPS try something with VB, we need you as a resource there'.
As I know nothing head/tail there, I wanted to try my hand by any 'quick reference' or 'kick start' on VB. VB 6.0, will do for me now, will migrate to .NET, when my company gets that stuff.
Links, tutorials are welcome....
Thanks a lot

My problem seems to be an issue of generating random numbers. While the statements are quite clear and easy and all of us are familiar with it, I never can seem to come up with a set of truly random numbers, while hating to sound totally stupid and an idiot, it has been quite frustrating. I have used the "Randomize" statement, but it seems to not work very well or I have overlooked something that is far too easy. The program I am creating relies on a set of truly randome numbers to function.
I use Visual Basic.net and I also Have Visual C++.Net as well, maybe I should switch gears and use another programming language??

Computers cannot pick truly random numbers.
They can't make guesses...
They don't feel pain, or remorse...
Oh, sorry... getting carried away there.

i had a similar problem with vb.net first i had coded the game yahtzee in vb6 and it worked fine then i was converting it into vb.net and after i got all the stuff out of the way i ran it in debug mode and i saw i got 5 random numbers which i use to change the pictures of the die showing but when i took it out of debug mode i get the same five numbers like i get all 1's or all 2's etc but the moment i put it into step by step debug it works perfectly again so maybe its a bug in .net cause i got pretty pissed off because i thought how in the hell do i debug something that works perfect in debug mode? don't know if this helps or not

Hi,
I want to copy a Table (in sql server) to a specified Text File programmatically using DTS.Can any one help me?If possible can u please paste the code?
Thanks in advance
|

You can do this one of three ways.
1.) The best way is to use an ADO Recordset / ADO.NET DataSet and use the "Save" / "WriteXML" Methods. This is best because both the Recordset and DataSet can open an XML file.
2.) Use BCP to Bulk Export data from the Table to a Text File. This is essentially what the DTS does.
3.) There is also a way to Bulk export using an XML format but I can't remember the command.
Not all those who are lost are looking to be found. But of those who are lost and those who are found, all are looking for something higher than themselves.

Hi,
I build a .NET COM class that has a method (Print) with some parameters:
.NET Code:
Class Print
Public Function DoPrint( _
ByVal PDFPath As String, _
ByVal PDFName As String, _
ByVal Printer As String, _
ByVal sSQLCol() As String)
VB6 Code:
dim cPrint as New Print.DoPrint
Dim stringSQL1, stringSQL2 as String
Dim SQLArray() As String
stringSQL1= "SELECET * FROM TABLE1"
stringSQL2 = "SELECT * FROM TABLE2"
SQLArray(0) = stringSQL1
SQLArray(1) = stringSQL2
cPrint.Print(pdfpath, pdfname, printer, SQLArray)
When I try to compile the VB6 app it gives me the following error:
"Function or interface marked as restricted, or function uses an Automation type not supported in Visual Basic"
How can I do this?
Many thanks in advanced.
Pedro

I didn't know you could initialize a variable to a method ( DoPrint is a method). Perhaps that's where the error is??

Hi,
Sorry, You are rigth!! I copied the code badly. 
So here it is the correct code:
.NET:
dll Name -> Print
Class Name -> CReport
Method -> DoPrint
VB6:
dim cPrint as New Print.CReport
Thanks

Dim stringSQL1, stringSQL2 as String
Perhaps it's this part. When do this in vb6, stringSQL1 is dimensioned as a variant datatype. So you're actually passing variant when you're supposed to be passing string.
You should declare it like this
Dim stringSQL1 as string, stringSQL2 as string

As control array is no more supported in VB.NET ,but i have more than 100 textboxes in my form ,I want to access those with help of index in a loop ,as shown below
for i=0 to n
txtName(i).text=i.tostring
next
How it is possible please help me with source code.

Hi,
Why so many textboxes??? Isn't it a bit hard to with for the end user???
If you open your controlbox window you can find a wrapper for control array's
Go to your customize Toolbox window.
Then select the tab ".NET Framework Components"
Find the component "TextBoxArray"
that's the compatibility component for the control array.
but why not redesign your application to use less textboxes or assign the same eventhandler to one event and check on the "sender" variable.

This doesn't work. I thought declaring a variable as public in a class made it global.
Public Class Form1
...
Public i as integer
Private Sub Form1_Load(...
i = 1
End Sub
End Class
Public Class Form2
...
Private Sub Form2_Load(...
Dim j As Integer
j = i  compiler says i is undefined
End Sub
End Class
|
|
|
|
|
well, i and j are in different classes so they cannot see each other.
now, if your instance of Form1 is global, then you can access i through it like this.
Global instance of Form1:
Public MyForm1 as Form1
Access instance of Form1 in class Form2:
Public Class Form2<br />
...<br />
Private Sub Form2_Load(...<br />
Dim j As Integer<br />
j = MyForm1.i<br />
End Sub<br />
End Class
