Use the database for storing Data.
label for asking Que.
Checkbox when the ans is more then one.
optionbox when the ans is single.

Use a text file. That would be funny.
( seriously, use XML or a DB )

Thank you, I am going to use a database (Open office).
Do anyone have some sample code on how to start with this program.
|
|

open office ? Why ? You should use SQL Server Express, it's free and it's well supported in .NET.
It's an easy task, you just need to design your DB to associate questions and possible answers, then write code to step through questions.

Shure like Christian said the express edition is free so you can install it on the pc (or include it in your setup to install together with your program)

Hello,
VS2008 SP1
<br />
Private Function IsPortAvailable() As Boolean<br />
Using sock As New Socket(AddressFamily.InterNetwork, _<br />
SocketType.Dgram, _<br />
ProtocolType.Udp)<br />
sock.Connect(VaxSIPUserAgentOCX.GetMyIP(), 5060)<br />
Return sock.Connected<br />
End Using<br />
End Function <br />
Using this code I thought I had this problem solved. However, after testing I have found that the socket always connects. Even if the port is being used by another application.
The port I am checking is 5060 UDP. My application when it starts will check if this is available. If another applications is using it. i.e. SJ Phone etc. The application will inform the user.
However, the socket always returns true. I have checked this with netstat -aon (cmd) and I can see that the port is being used.
I am checking the port on my local computer. So my IP address is 10.10.10.120. Under the netstat I can see this 0.0.0.0:5060. Why all the zeros. Could this be part of the problem
Is there another method for checking this?
I have looked at udp client, and wondering about winsock.
Thanks,

Hai friends,
X=50
Y=100
SendMessage hWND, WM_MOUSEMOVE, 0&, lparam
My question is, how to pass the X, Y to lparam since it accept only one value?
pls help.
|
|

|
|
Hi,
typing "WM_MOUSEMOVE" in the Google search box and reading the first hit would have taken less time and less effort than entering your message and waiting for a response...
|
|

Hai,
Yes, the first result really takes in to the MSDN documentation.
but no example is given 
what i need is an example and with a short explanation on how to post the values.

The documentation DOES provide an answer to your question.
MSDN wrote: lParam
The low-order word specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.
The high-order word specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.
lParam = x or (y << 16)

I'd give this a 5, but post voting is broken for Safari.

All that remains to be done is you buying a real computer, or Chris fixing the Safari voting bug

ROTFL - well, if IE was not crap, I'd use IE for CP, in XP, on my Mac.

I'm happy running FireFox on Vista, except for some companies (banks) and governmental organizations that only support IE.
Did you consider FireFox on Mac?

I am aware that it exists, but I've never hated Safari like I hate IE, so I've never felt enough motivation to install it. I ran FF on my old PC.

Hi, I have tried this every which way but loose (maybe I should have tried that one as well!)
I need to select rows from a datatable based on a date column but no matter how I format the date it just errors.
The sample in MS help does not work either.
Microsoft Example
'Presuming the DataTable has a column named Date.
Dim expression As String<br />
expression = "Date > '1/1/00'"<br />
Dim foundRows() As DataRow<br />
<br />
' Use the Select method to find all rows matching the filter.<br />
foundRows = table.Select(expression)
My Code
dteTStart = Me.m_dteCurrentGraphStart.AddDays(-1)<br />
dteTEnd = Me.m_dteCurrentGraphEnd.AddDays(1)<br />
strFilter = "TradingDate > '" & dteTStart.ToString("MM/dd/yyyy") & "' AND TradingDate < '" & dteTEnd.ToString("MM/dd/yyyy") & "'"<br />
Dim drowData As DataRow() = m_dtblROIData.Select(strFilter)
The error message
Cannot perform '<' operation on System.DateTime and System.String.
Does any one have any idea how to get round this?
Thanks

Use the System Format date that available in Control Panel.
Same think use in code with the format statement.
Ex.
dat=format(today,"dd-MMM-yyyy")
and if u have error in access data statement use SQL Query.
