try "" inside your literal string
so just a double quote would look like """"

Hi Friends,
I need to check the LAN connection status by using vb.net 2003(web application).
for ex:
you can assume that 10 machines are connected with each other any one of the machine is disconnected for the LAN means I have to know the status of disconnected machine status and connected machine status.
Do the needful
Thanks in Advance,

I created a "UserControl" with about 260 controls, about 70% of them are UserControls with about 3 windows forms such as TextBox, ComboBox and DateTimePicker (which I will call "simple usercontrols" from now on). These 260 controls are spread over 7 TabPages of a TabControl.
From a certain point of the development on, the IDE hasn't shown the simple usercontrols any more (except for one of the tabpages in which the controls are still visible).
- The code, which is created automatically by the windows form designer seems to contain all the needed code for the controls in the same way as before, as far as I can see.
- In the form designer, the simple usercontrols are still listed in the combo within the propery window. When I select a simple usercontrol via this combo, it is marked in the form designer (surrounded by this typical rectangle telling the size of the control) though it is still invisible.
- The executable is ok, i.e. the "simple usercontrols" are visible.
To get rid of the problem I tried the following: I went back to a version of my usercontrol which didn't have this problem, added a few further controls and the same problem occured again.
Does there exist an upper limit of controls a form disgner can handle?
If someone has a hint/an idea to solve the problem, that would be really great. - Thanks in advance,
Michael

Look at the documentation for <a href="http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.cursor.aspx">Cursor</a>[<a href="http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.cursor.aspx" target="_blank" title="New Window">^</a>]. What type does it say it accepts?

There is settings which configure your project with strict type conversion or normal (like in vb 6, as you know you can assign an integer variable a string value like "147" it works fine in that).
Go to solution explorer, right click on you project definition (not solution one) and open its property.
A widow will be opened and now click on compile option there will be a combobox for Option Strict change it to on.
This will strict you to assign valid values to particular variables.

C:\Inetpub\wwwroot\HSBC.NET\frmSupManualSearch.vb(582): 'frmOutBound_manual' is a type and cannot be used as an expression.
when statment is ...
Load(frmOutBound_manual)
where frmOutBound_manual is the name of the form....

soniasan wrote: where frmOutBound_manual is the name of the form....
Incorrect. frmOutBound_manual is the name of the class that represents the form. A class is a specific kind of "type" (e.g. enums, structs are also "types")
You need to provide an instance of the class. If you do not have an instance already that you want to use then you have to create an instance of the class.
To create an instance of the class use the New keyword. Something like this:
Dim myForm As frmOutBound_manual = New frmOutBound_Manual()

Hi ALL
i am migrating the vb application which con.tains the OCX Control
to that of the .net project i Choose Vb.Net
But when in .net i create maually aspx pages.
and i copy that class modules also...
but i am not getting that events.
How i will convert that OCX control into that of vb.net project so that i can access
the events......
waiting for your kind response.....

Make sure what application you want to develop.
Web application (web sites) cannot have ocx controls. I think you want to develop windows application and by mistake you have chosen web site/application because web sites/application will have aspx extension.
Just select language vb/c# and select Windows Application project (new project)

my VB.net application uploads local files to server. Every second my application need to detect whether my application still connected to that server or lost connection, how i can detect the connection lost or still connected ? using shell or ping ? how to use it ?
Regards,
Chee ken

firstly I would not check the connection every second, I would only check it just before I upload the file.
I use a function like the following to check if a connection exists :-
Public Shared Function IsWebSiteAvailable(ByVal Address As String) As Boolean<br />
Try<br />
Dim oUrl As New System.Uri(Address)<br />
Dim oWebRequest As System.Net.WebRequest = System.Net.WebRequest.Create(oUrl)<br />
Dim oResponse As System.Net.WebResponse = oWebRequest.GetResponse<br />
oResponse.Close()<br />
oWebRequest = Nothing<br />
Return True<br />
Catch<br />
Return False<br />
End Try<br />
End Function
There I would the code the upload as follows
If IsWebSiteAvailable("www.mysite.com") Then<br />
DoUpload()<br />
Else<br />
MessageBox.Show("Internet connection unavailable.")<br />
End If<br />

I want to put a Double Quote (") in a string. if I give it in a string, then the string terminates at the position where the Double Quote is put.
Can anybody suggest how to put a Double Quote in a string ?
Thanks In advance.

Try """".
e.g. "This is a ""TEST"" string"
|
|
|
|

Hi,
In regards to your query I would like to inform you that in order to print double qoutes in a sting we have to use two double quotes (e.g., ""). We can print the double quotes in a string as follows:
BEGIN CODE
Dim str As String = "I ""Love"" VB "
MsgBox(str)
END CODE
The output will be I "Love" VB.
I hope this helps .
Regards,

Use ChrW(34)
Like this:
TextBox1.Text = ChrW(34) & "This is a string." & ChrW(34)
The output would be:
"This is a string."
You can put any character in ChrW(.) by looking at this page: http://www.utoronto.ca/webdocs/HTMLdocs/NewHTML/iso_table.html[^]
As you can see, the double quote char is decimal 34.
