how can i get complete system information through VB / VB.NET
Regards

Define complete.
You can access:
System.Management, for WMI.
WMI has a lot of info in it.
System.Environment, for general local machine stuff.
System.DirectoryServices, for active directory.

Hi, you can use the Process class to execute file
C:\Program Files\Common Files\Microsoft Shared\MSInfo\msinfo32.exe
You would need a lot of code it you wanted to obtain most of that information
into your program's variables.
|
|
|
|
|
You can also use the shell function call the "dxdiag" command
just use
shell("dxdiag")
it will open a window with all system information
or use
my.computer.BLAHBLAH
namespace and get the system information
hope it will help

cmd.Connection.Close()
If cn.State = ConnectionState.Closed Then
If cn.State = ConnectionState.Closed Then
cn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=ehab.mdb"
cn.Open()
End If
cmd.Connection = cn
cmd.CommandType = CommandType.Text
End If
Dim s As String
Dim h As Integer
s = 0
h = 0
Dim f1, f2, f3, f4, f5, f6, f7, f8 As String
f1 = "'" & DateTimePicker1.Value & "',"
f2 = "'" & ComboBox1.Text & "',"
f3 = "'" & ComboBox2.Text & "',"
f4 = "'" & TextBox1.Text & "',"
f5 = "'" & TextBox2.Text & "',"
f6 = "'" & TextBox3.Text & "',"
f7 = "'" & TextBox4.Text & "',"
f8 = "'" & Label10.Text & "'"
s = "insert into sale "
s = s & " (dte,op,value,nos,cost,coms,nii,npp )values "
s = s & "(" & f1 & f2 & f3 & f4 & f5 & f6 & f7 & f8 & ")"
cmd.CommandText = s
h = cmd.ExecuteNonQuery()
MsgBox("Saved succssefuly")

On the line:
s = s & "(" & f1 & f2 & f3 & f4 & f5 & f6 & f7 & f8 & ")"
You need to seperate the values with commas
s = s & "(" & f1 & "," & f2 & "," & f3 & "," & f4 ... etc
I would recommend using Stored procs though as you are performing no validation and are wide open to injection attacks

Could you give an indication as to the error which is being returned from SQL when you try and execute the query?

Is this an exact copy from your code? If so, there is an extra ' at the end.
Also, what is the type of field dte in your database? If it is a date, you cannot pass in a string, AFAIK.
What is the error message you get, anyway?

|

he gives me this error msg
Syntax error in INSERT INTO statement.
all of the fields in database are number except dte it's type (date/time)
plz help me cause it drive me crazy

Ok - but did you check out the suggestions I made earlier? Date fields cannot be passed in as strings to Jet databases.

syntex error
do u have another solution
i have already use this code in another form and it works well (in my first topic )
i don't know what's wrong
|
|
|
|
|
he gives me error when i tried to enter 2 values
this is the error
syntax error (missing operator) in query expression '7/2/2007Vodafone'.
|
|
|
|

magedhv wrote: syntax error (missing operator) in query expression '7/2/2007Vodafone'
It looks like you dont have the two fields separated - shouldnt it be '7/2/2007','Vodafone'...
Also, the first is a date field, IIRC date fields for Jet databases should be enclosed by # not quotes.
|
|
|
|
|
plz write 4 me the code of the date to try
thanks i appreciate your efforts
|
|
|
|
|
Just remember this...
for text (string) variables, enclose data in quotes - like 'Vodafone'
for number variables, just the value will do
for date variables, enclose data with # - like #7/2/2007#
and between each field, you should have a comma.
Hope this helps.

do u mean like that
dim x as string
x = "'" # DateTimePicker1.Value # "'"
if that's what u mean the visual basic underline the last line (x = "'" # DateTimePicker1.Value # "'" )
plz try to write the whole code and note that the same code i use it with the same string in other form and it worked well
|
|
|
|
|
magedhv wrote: x = "'" # DateTimePicker1.Value # "'"
Thats not what I mean...
try this:
x = "#" & DateTimePicker1.Value & "#"

Ignore ALL the other replies you've gotten in this thread. They're all crap.
Drop all this string concatenation garbage and do it the correct way with a parameterized query. See this article[^] by Colin Angus Mackay for more information as to what they are and why your shooting yourself in the foot doing it your way. You're actaully making is harder on yourself by building a string for your parameters.

could u plz tell me what should i do because i read this topic but i didn't understand what to do
so if u have any idea about what to do simply tell me
and thanks i appreciate ur efforts

I did "simply" tell you. You're building an SQL query by appending multiple strings together. This introduces the opportunity for a lot of bugs and security holes into your code.
Read the article I gave you a link for and about half way down, it'll explain what a parameterized query is and how to put it together to solve most of your security and readability problems.

Hi,
I'd like to know how i can get the mouse position in an image loaded into a picturebox. (The Image is stretched) If i use MousePosition i get the position of the mouse on the form, and i want to get the mouseposition on the image loaded into the picturebox. Again, the image is stretched so a x value of 1000 could be a x value of 1500 in real.
Help, please?

To do this, you cannot rely on the picturebox painting the picture for you. You have to supply the code to paint the picture yourself. This is because in order to map the mouse point coordinates in the picture box to the image its displaying, you MUST know the scaling values being used to scretch the image. Since the picturebox doesn't expose these to you when it draws the image, you have to calculate the scaling values yourself.
