Well, first off, it's pretty each to convert C# to VB.NET. There's also a bunch of online conversion tools that'll do some of it for you.
You might also want to take a look at this[^] on MSDN for another example.

You can try like this.
dim xyz as string
xyz.substring(startindex) and other overloaded form of this function is
xyz.substring(startindex, length)

Hi Soodmonu
many thank for your reply I have tried that operation but it doesn't working well, and Now I saw you my simple program as follows
dim a as double
dim b,c as string
a=03.00
b=str(a)
c=b,substring(4,2)
when I tried to run my program an error message was come, I wanna to show two last character from "a" into my screen and it supposed to be "00" but I could not catch it,
could you mind to tell me how to do that ?
Thank you
ICE

Here the problem is type casting from double to string.
let me explain you....
first of all when u declare a double variable as 03.00, the value stored in variable will be 3.0
and when u type cast it to string, it will store as "3" only.
so as you can see there is no fourth character in string, substring does not return anything.
now what you can do that is :
Dim a, c As String
a = "03.00"
c = a.Substring(3, 2)
here in the substring function index is a zero based index, so you have to pass 3 to get the fourth character.
and if you donot want to declare as string in the starting and want to proceed with double only, then find some help on double.tostring() function, i think that function can help
it should be like
Dim x As Double
Dim a, c As String
x = 3.0
a = x.ToString("0#.00")
c = a.Substring(3, 2)

where can i find samples of projects and stuff for downloading in this web site
|
|
|
|
|
As far as I know, there is no single download page. All code snippets are associated with articles. Here is how:
1) On the Menu Bar, select Articles->Site Directory, or
2) Also on the Menu Bar, search for your key workds
Best,

Actual code from the debug window of a VB6 application. I noticed a problem this morning, got distracted and just came back. Does anyone have a way of explaining this?
? now() > g_endtime
True
? now()
6/28/2006 9:14:06 AM
? g_endtime
6/28/2006 10:13:44 AM
? now() > g_endtime
False
? now()
6/28/2006 2:17:07 PM
? g_endtime
6/28/2006 3:16:47 PM
|
|
|
|
|
Not enough information. What type is g_endtime? It would appear that it's a String.
If you compare the two as strings, the answers come out as expected. "6/28/2006 9" is greater than "6/28/2006 1".

I am writing an application in VB.NET that needs to run against both WSS & SharePoint Portal. One of the things that this application needs to do is display all of the top-level URLs in a drop down menu. I can't figure out how to connect to the local SharePoint box to discover these items.
Any help would be greatly appreciated.
thanks!

Can you explain what you're thinking that means? Auto-resized based on what?

I want the form be auto resized based on the amout of data i have in this form:
it can be one textbox plus button and when i add another textbox the form will take the new size

U can resize the form dynamically through the code by setting the frmobject.size property.
|
|
|
|

Well, I've never had to do it, but I don't see why you couldn't just use the information you have to track where you're going to put the next TextBox control, and its size, to calculate how big the form has to be. Then just set the form's Height and Width properties.

I understand sending variables by val and by reference but what is sender exactly. I mean I get it's the sub that called this sub but I'd think it would be passed by reference. I need some more explanation on it and I can't find it Googling it.
Thanks

No, it's not. sender represents the object that through the event that you're now handling. Since a single event handler, like Click, can handle the click event for multiple objects, like a bunch of different buttons, you need a way to find which of those buttons through the event. You can cast sender as a Button, then check it's name property, or change it's Enabled state, or colors, image, ... whatever.
Private Sub MyClickHandler(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click
Dim b As Button = CType(sender, Button)
b.Enabled = False
End Sub

That kinda makes sense but isn't it odd you can't just say sender.enabled=false?
|

It makes perfect sense that you CAN'T do it.
Look at the parameters for the event handler. The first one, sender, is n System.Object, which is essentially just a container for every type of object known. Just about EVERYTHING is a descendant of the System.Object class.
Note that the System.Object class doesn't have an Enabled property. If you just specified any old property or method, how would the compiler know how to call it?
For example, you can use the same event handler to handle multiple events for multiple controls. They don't ALL have to be buttons. You can have a mix of buttons, checkboxes, panels, ..., anything else all using the same Click event handler. You can also mix events. The same handler can handle multiple types of events, so long as every event signature (parameters) is the same.
Now, knowing this, how is the compiler supposed to know what kind of object to automagically cast the sender parameter to in order to call it's properties and methods?
