Does anyone know if it is possible to run a .dll as a service in Windows 2000? If so, can you give me some insight on how to do it?
Thanks!

I have got a textbox that I want to limit to numerical values.
How do I prevent the user from entering text?
I have set the DataFormat property to "Number", but that doesn't do it.
Cheers,
Fredrik

Hi..
Try this:
add an event handler to the KeyPress event of the text box:
<br />
Private Sub text1_KeyPress(KeyAscii As Integer)<br />
If Not (KeyAscii > 47 And KeyAscii < 59) Then<br />
KeyAscii = 0<br />
End If<br />
End Sub<br />
the code above checks the ascii code of the character and validates the range
and sets it to 0 if out of the range of numbers.

Hi !
I'm using VB 6.0 and I would like to launch an Exe from my VB code. I also would like to get the returned value from the Exe.
Anyone knows how to do that ?
Thank you for your help !

You know. I'm surprised that Nish hasn't jumped in and said to use ShellExecute(..)... I know it's C++ but if you just search at MSDN you'll probably find something.

u have to use Shell Function in order to execute an exe and u use Command Function in order to get the return value from and even pass value to the exe.

I am a student at the faculty of engineering,Cairo university, depsatment of electronics and electrical communications.
My graduation project involves the use of the Diffie-Hellman key agreement protocolusing visual basic.I hope someone can help me locate something that can do the mathematical operations needed for such an algorithm.
Thank you.
|
|
|
|
|
What kind of math calculations are required in that algorithm?
BTW, you can use DLLs that are created for both Visual Basic and C. I am sure that someone has written a math library in C that can help.

I need exponentials for large numbers (160+ bits)
I found a dll called CypherMathWin32,but I can't get my hands on it.

I can't buy a 300 dollars DLL
Can any body help me in finding a DLL, an OCX, or any other written code that I can use to implement the Montgomery modular exponentiation?

How do u make a new line in text box programmatically in VB.NET?
I was hoping to use C++ format code "\n":
For i = 0 To (Count - 1) Step 1
txtMsgBox.Text = txtMsgBox.Text.Concat("\n" & lstContactList.SelectedItems(i).Text & txtMsg.Text)
Next i
But no, it didnt work.
Thanx

You can use :
<br />
txtMsgBox.Text=txtMsgBox.Text+ vbCrLf + "NewString"<br />
as vbCrLf = \n in VB
make sure that :
<br />
txtMsgBox.MultiLine=True<br />
|
|
|
|
|
Actually vbCrLf = \r\n, Carriage Return (Cr), Line Feed (Lf)
vbCr = \r
vbLf = \n

Try CrLf Carriage Return and Line Feed characters.
use one every time you want to start a new line.

All the previous versions of VB could not support MAPI to its fullest. Can VB.net?
If not is there any alternative for creating a complete email program with VB.net other than CDO?

hi, how can i use SetTimer in a class, i keep getting these errors:
Invalid use of adressof operator
my code is:
lngTimerID = SetTimer(0, 0, 200, AddressOf mysub)
Public Sub mysub(ByVal hwnd As Long, ByVal uMsg As Long, ByVal idEvent As Long, ByVal dwTime As Long)
Dim retval As Long ' return value
objWinSock.SendData ByteCode & "rcon " & rconNumber & " " & s_pass & " " & s_command
objWinSock.Close
Set objWinSock = Nothing
retval = KillTimer(vbNull, 1)
End Sub
|
|
|
|
|
In VB6, the AddressOf operator can only be used for procedures in a module, not a class. To see how to work around the problem, look here.

Hi, I wish to build a control that resembles those panes, "ToolBox" for example, that "slides" into the view when click on the tab.
1. Is there a name for these controls?
2. Any idea how to build them?
3. How can I set a "control" opacity? Can I control individual individual "control" opacity as suppose to controlling dialog opacity?
Something similar to what u can see at bluetooth site:

Thanks!

I'm working on a program that is the front end for a database (Access). One of the fields in the data base is set up to use options set in the field's 'Row Source' during design of the database. (When viewing the records in Access it comes up as a list box) I am wondering how I can get the options for that field into my program without hardcoding them. I can get the option that is currently chosen for a record back, but I need to know how to get ALL the possible options for that field. I'm using ADODB objects to access the database. Any help or pointers in the right direction will be much appreciated.

If you are using the ADO object in your application, do a simple query:
Select [YourField] from [YourTable]
Once you have executed that SQL statement say when the form loads, you can add items with something like:
ListBox.Clear()
Do While Not adors.EOF
ListBox.Add(adors("[YourField]"))
Loop

That didn't work. Stoopid IE made me lose my reply and I'm too tired to type it again. In short, that will only return the one option that a row has as a value. If one of the options were never selected it wouldn't show up in the list box. Thx though. Anything else you can suggest?
