Try restructuring the query...
select * From MultipleChoice AS MC<br />
JOIN MultipleChoiceAnswer AS MCA ON MC.multipleChoiceID = MCA.multipleChoiceID<br />
JOIN Level AS L<br />
ON MC.levelID = L.levelID<br />

Set FormBorderStyle property to None
Set the BackgroundImage property to the image you want to use
Now set the TransparencyKey property to the background color of the image.
Run you app
Note: When I tried to do this by using VB.Net 2003 it didn?t work. Solution to this problem is reseting the screen to use color values that are 24 bits or less. In Vb.Net 2005, it works fine.
If the background color of the image appears in your image too, you can see holes in your image, therefore, do not use a common color as the background color of the image.

i've also noticed that not all video cards will make the backgronud color transparent, so be aware that someone running your app could still see the original shape of the form

Hi Guys,
Well I'm totally stumped. I've got a bit of vbscript code that tries to find a particular process running on a machine (Windows NT). If the process exists I want the text ("I am running...") displayed. If it doesn't exist then I want the text ("I am not running") displayed.
Just some background on the OS. Its Win NT 4 service pack 6 and i reinstalled WMI Core 1.5
On win xp, win 2k and win 2k3 the script below works fine. However on windows nt where this will reside on it fails giving me an error 80041001 which I belive is a "Call failed" error.
Can anyone shed some light on why this would be happening on NT in particular? Thanks in advance
<%
Dim strComputer, strProcess
strComputer = "."
On Error Resume Next
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}! \\" _
& strComputer & "\root\cimv2")
Set colProcess = objWMIService.ExecQuery _
("Select * from Win32_Process")
For Each objProcess in colProcess
do while objProcess.name = "Someprocess.exe"
strProcess = objProcess.name
'objProcess.Name
'If objProcess.name = "Someprocess.exe" then
Response.Write ("I am running...")
'Else
'End If
Exit Do
Loop
Next
If strProcess = "" then
Response.Write ("I am NOT running")
End If

Does the account the this script is running under have at least PowerUser permissions to the machine you're monitoring?

How do I set the permissions for users in Windows NT? The interface is not what Im used to and Im not sure how I can change it. Thanks
|
|
|
|
|
What user account is this script running under??? Is this script in a web page?? Does the script run on the server or on the client side?? Are you running it by double-clicking a *.VBS file??

The script is in a webpage and runs on the server. How do I determine which account is running that script. I would have though it would have been the IUSR_xxxxxxxx account or am I wrong?
|
|
|
|
|
It'll be that account and, No, it doesn't have sufficient rights to do what you want. Add that account to the Power Users group and it'll get the rights it needs. BUT!!! BEWARE!!! This ia a HUGE security risk if your NT server is visible to the Internet.

Where do you actually setup the permissions for accounts in Windows NT?

Here goes the question with the code, I can't find how to append a zip with code, but you should be able to copy-paste and compile the code on the bottom after question
the first part is how to call this warning window through a tread
AlertWindow is the class that displays the message
Dim aFrmAlertPopUp As New AlertWindow("oi", "test", "123", "A", "dude", "joe", "joe", "A", ListView1, "", "123", "123")
if you invoke like this, it just works fine:
aFrmAlertPopUp.display()
if you invoke through a thread, it does go through (i see it steping though with VS) but won't show
'Dim t As New Thread(New ThreadStart(AddressOf aFrmAlertPopUp.display))
't.IsBackground = True
't.Start()
End Sub
The freaky thing is that if you add a msgbox("hello") in one of the methos of aletwindow, it works fine, but i don't want the message box to pop. why is it happening, is there anything that a message box triggers that i am not addind on that method
Private Sub startDisplay(ByVal displayCall As String)
setWarningProperties(displayCall)
lblBody.Text = message
lblSysOrigin.Text = sysOrigin
setLocation()
Me.Opacity = 0
Try
Me.Show()
currentTimer = timerFadeIn
timerFadeIn.Start()
Catch err As Exception
MsgBox(err.Message)
Finally
MsgBox("23")
End Try
End Sub
here is the whole code for AlertWindow.vb:

OK. First, your post is EXCESSIVELY long. I, for one, am not looking through all of this to find out what you're doing right and not doing right.
But, as a rule, ALL UI elements, including forms, should only be shown on the UI thread. NOT from a background thread. This is because forms put up on a different thread are cut off from the applications message pump, which only exists on the startup thread.
After just briefly scanning throught his code, I fail to see why you need to start a background thread to put up this form anyway.

timer1 interval = 100
timer1 enable = false
-----------------------------------------------------------------------
Dim mscomm1 As New MSCommLib.MSComm
Send AT command to modem
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click<br />
<br />
Try<br />
mscomm1.CommPort = 3<br />
mscomm1.PortOpen = True<br />
mscomm1.Output = "AT#CID=1" & Chr(13)<br />
<br />
TextBox1.Text = TextBox1.Text & mscomm1.Input<br />
<br />
<br />
mscomm1.Output = "AT%CCID=1" & Chr(13)<br />
TextBox1.Text = TextBox1.Text & mscomm1.Input<br />
<br />
mscomm1.Output = "AT+VCID=1" & Chr(13)<br />
TextBox1.Text = TextBox1.Text & mscomm1.Input<br />
<br />

I am trying to bind a picturebox (and its associated picture) into a MS Access dB. I have been reviewing several snippets of code but each seem to confuse me more. I have everything working properly in regards to data binding textboxes but the picturebox is going easily.
I want to be able to bring up an openfiledialog box (from a browse button), browse for the image (jpg, bmp, tif, gif) and then scale it to the picture box size and allow the picturebox to adjust itself for portrait or landscale layout. Then I want my already existing save button to bind the picturebox with the rest of the data to an MS Access database.
Any help would be greatly appreciated! Thank you!!

i am using vb.net 2005 and sql server 2005. i am save image this code ; select picture openfiledialog ;
<br />
<br />
Imports System.Data.SqlClient<br />
Imports System.IO<br />
<br />
Dim con As New SqlConnection("Data Source=.\sqlexpress;AttachDbFilename=|DataDirectory|\GlobalREST.mdf;Integrated Security=True;User Instance=True")<br />
Dim da As New SqlDataAdapter("Select * from URUNLER", con)<br />
<br />
da.MissingSchemaAction = MissingSchemaAction.AddWithKey<br />
Dim MyCB As SqlCommandBuilder = New SqlClient.SqlCommandBuilder(da)<br />
Dim ds As New DataSet()<br />
<br />
Dim fs As New FileStream(Me.ButtonEdit1.Text, FileMode.OpenOrCreate, FileAccess.Read)<br />
Dim MyData(fs.Length) As Byte<br />
fs.Read(MyData, 0, fs.Length)<br />
fs.Close()<br />
con.Open()<br />
da.Fill(ds, "URUNLER")<br />
Dim myRow As DataRow<br />
myRow = ds.Tables("URUNLER").NewRow()<br />
<br />
myRow("URUNKODU") = TextEdit2.EditValue<br />
myRow("URUNADI") = TextEdit3.EditValue<br />
myRow("URUNGRUBU") = "6"<br />
myRow("FIYAT1") = TextEdit4.EditValue<br />
myRow("FIYAT2") = TextEdit5.EditValue<br />
myRow("FIYAT3") = TextEdit6.EditValue<br />
myRow("FIYAT4") = TextEdit7.EditValue<br />
myRow("ACIKLAMA") = Me.MemoEdit1.EditValue<br />
myRow("RESIM") = MyData<br />
<br />
ds.Tables("URUNLER").Rows.Add(myRow)<br />
da.Update(ds, "URUNLER")<br />
<br />
fs = Nothing<br />
MyCB = Nothing<br />
ds = Nothing<br />
da = Nothing<br />
<br />
con.Close()<br />
con = Nothing<br />
<br />
<br />
but this code not work Access database. You are save picture file name and file location to access database. and select PictureBox component and expand DataBinding property click Advanced. Select PictureLocation value and select database picture location field.

Really simple:

where MultipleChoice.MID=MultipleChoiceAnswer.MID AND MultipleChoice.levelID=Level.LevelID
or
select *<br />
from MultipleChoice<br />
inner join MultipleChoiceAnswer on MultipleChoice.MID=MultipleChoiceAnswer.MID<br />
inner join Level on MultipleChoice.levelID=Level.LevelID
---
b { font-weight: normal; }
