hi,
I want to create a program for which user have rights to access limited programs rather than accessing entire program list.
According to the user permission, user can access the programs..
For Example...
For some user, Administrator wants to assign right to run only Inernet Explorer and MS office then a user can only able to access those applications.
For Other applications user should be restricted.
can you help me out?
Thankigg you.

You really can't write anything in code to control this. This type of work is normally done using Group Policies.

Hi I've created my web page using VB.Net. I'm using CuteFTP to upload my web pages. I can upload all other files except .dll files. While uploading .dll files I'm getting this error:
Requested action not taken (e.g., file or directory not found, no access).
Is there any other methods to upload the webpages (VB.Net)
Plz help me.

Upload them to what? A hosting server? You'll have to call the support line for your host to find out what's going on.

Hi Guys
I would like asking to you who have some experience with Visual Studio 2005 to help me how to make setup disk.
I have created a simple program it's build under Visual Basic.Net 2005 which was content in Visual Studio 2005,but when I tried to made Setup disk I culd not find some files like at the previous version, and the files at the previous version are
- Crystal_Managed2003.msm
- Crystal_Database_Access2003.msm
- Crystal_Daabase_access2003_enu.msm
- Crystal_regwiz2003.msm
Actually Those above files are needed when we want to made merge module in setup disk for project which was content crystal report inside.
I couldn't found those files in Visual Basic.net version 2005,does one of you know how to find those kind of files inside Visual Studio.net ver 2005 ? or maybe there is another way to made a merge files that will be binding all crystal report files in my Project ?
I do hope you will help me to quit from this problem
Thank you

VB.Net/MS Access. I need to insert records into a particular table (say X)after getting the data from two different tables (say A & B) and doing some permutations and combinations on it. I am getting entire data from tables A & B into two different Datasets. A loop has been written to parse the records from A (dataset), check in B(dataset) and insert the record in table C. However, this entire process is taking a long time. (i.e: in my test run, to insert around 8 lakh records, it took approx 4 hrs).
As per my perception, the time delay is being caused since I am firing an insert statement directly on the database during every loop cycle. Is there a way to avoid this and speed up the process. (i.e. Can the records be inserted into a dataset and then all the records be directly inserted into the table from the dataset)
Please help me its very urgent !!! Sorry for the long description
With Best Regards,
Mayur

Without seeing any of the relevant code, it's impossible to tell you what's going on.

Sorry once again I am providing a huge chunk of code below. Please review it and provide me with some ideas to speed up the process.
Code :
----------------------------------------------------------------------------
str = "select id, code, name, period from EMP2000"
ipcon.Open()
DA = New OleDbDataAdapter(str, ipcon)
DS = New DataSet
DA.Fill(DS, "irec")
str2 = "select id, code, addr, period from EMPADDR"
DA2 = New OleDbDataAdapter(str2, ipcon)
DS2 = New DataSet
DA2.Fill(DS2, "imsctrl")
DV = New DataView(DS2.Tables("imsctrl"))
str3 = "select Id, code, name, addr from EMPDATA where period = '2000'"
DA3 = New OleDbDataAdapter(str3, ipcon)
DS3 = New DataSet
DA3.Fill(DS3, "emp")
Dim cb As New OleDbCommandBuilder(DA3)
Dim cnt As Integer
cnt = 0
'''
Dim DataRow As DataRow
For Each myrow In DS.Tables("irec").Rows
If (myrow(1).Equals(System.DBNull.Value)) Then
code1 = ""
Else
code1 = myrow(1)
End If
If (myrow(3).Equals(System.DBNull.Value)) Then
period1 = ""
Else
period1 = myrow(3)
End If
If (myrow(2).Equals(System.DBNull.Value)) Then
name1 = ""
Else
name1 = myrow(2)
End If
For Each DataRow In DV.Table.Rows
If Trim(DataRow(1)) = Trim(code1) And Trim(DataRow(3)) = Trim(period1) Then
addr1 = Trim(DataRow(2))
Exit For
End If
Next
dsNewRow = DS3.Tables("emp").NewRow
dsNewRow.Item("code") = Trim(code1)
dsNewRow.Item("name") = trim(name1)
dsNewRow.Item("addr") = Trim(addr1)
DS3.Tables("emp").Rows.Add(dsNewRow)
DA3.Update(DS3, "emp")
Next
----------------------------------------------------------------------------
Dave, Is there a way to insert all the records in a dataset and finally update the dataset to the database? If there is such a way then is it really fast. Thnx for your help.
With Best Regards,

Convert these to parameterized stored procedures.
Only grab the data you need at the time.
It looks like you're retrieving every employee in the table EMP2000, then going to another table and grabbing all of their addresses, then your grabbing more name and addresses according to some WHERE statement. WHY????
Do you really need all this information at any one point in your code??? I doubt it! You could retrieve all the RELEVANT stuff in one SELECT statement! But, only get what you need at the time. If you updating someones name, you don't need to retrieve the entire database!
The only thing slowing your code down is your own logic.

Thnx for your reply. I guess you did not understand my requirement. I need to get the address of each employee and insert the info into another table. EMP2000 contains only the emp code,name and period. EMPADDR contains emp code,addr and period. I need to link these and insert each employee record in EMPDATA.

General Question: Why would a program exit after a dll call without any error given? Is there any way to find it an error occurs or what the error is within a dll?
Very Specific one:
The following shows some dll declaration conversions for DVP1412.dll (see link at bottom).
The first 2 methods are called and return values that would be correct, however the third call will close program without giving an error while trying to initialise the board.
VB.NET code with VCpp declarations commented out:
<br />
<StructLayout(LayouKind.sequential)>Public Class DVPCaptureCard<br />
'int DVP1412_CreateSDKInstence(void **pp);<br />
Declare Function DVP1412_CreateSDKInstence Lib "DVP1412.dll" (<MarshalAs(UnmanagedType.LPStruct)>ByRef pp As DVPCaptureCard) As Int32<br />
'virtual int DVP1412_GetNoOfDevices() = 0;<br />
Declare Function DVP1412_GetNoOfDevices Lib "DVP1412.dll" () As Int32<br />
'virtual int DVP1412_InitSDK(int NoOfDevs, int* IDList) = 0;<br />
Declare Function DVP1412_InitSDK Lib "DVP1412.dll" (ByVal NoOfDevs As Int32, ByRef IDList As Int32()) As Int32<br />
....<br />
.... rest of methods<br />
end class<br />
<br />
'then on the main form<br />
Private Sub Form1_Load( ....)<br />
Dim cap as DVPCaptureCard = new DVPCaptureCard()<br />
result = cap.DVP1412_CreateSDKInstance(cap) ' result = 1 (success)<br />
result = cap.DVP1412_GetNoOfDevices() ' result = 1 (1 card is connected)<br />
<br />
Dim pn(16) as int32<br />
result = cap.DVP1412_InitSDK(1, pn) 'program exits here and doesnt reach next line, no error shown<br />
<br />
....<br />
....<br />
'program closes early: The program has exited with code 0<br />
The method declaration seems ok because changes to it will return an incorrect parameter value from the method (and wont crash) but with what seems the correct use it will crash.
anyone been able to use DVP1412_InitSDK with the DVP1412 board?
original Visual Cpp code is from http://www.advantech.com/support/detail_list.asp?model_id=DVP-1412[^]

It's not complete solution. But you can change as you like.
It use SQL Server database.

Dim conStr1 As String
Dim con1 As SqlClient.SqlConnection 'ADODB.Connection
Dim cmd As SqlClient.SqlCommand
Dim rd1, rd2, rd3 As SqlClient.SqlDataReader 'ADODB.Recordset

Dim strUserName As String = "sa" 'set your user name
Dim strPwd As String = "sa" 'set your password
Dim strDatabase As String = "pubs" 'set your database name
Try
conStr1 = "packet size=4096;user id=" & strUserName & ";password=" & strPwd & ";data source=TEST-PC;persist security info=False;initial catalog=" + strDatabase
'conStr1 = "provider=SQLOLEDB;data source=" & DellServerIP _
'& ";database=pre_sms;uid=sa;pwd=" & DellServerPass
con1 = New SqlClient.SqlConnection(conStr1) 'ADODB.Connection
cmd = New SqlClient.SqlCommand(Nothing, con1)
If con1.State = ConnectionState.Closed Then con1.Open()
'rs1 = New ADODB.Recordset
'rs1.ActiveConnection = con1
'rs2 = New ADODB.Recordset
'rs2.ActiveConnection = con1
sql1 = "SELECT TOP 20 * FROM TT_Member WHERE Reminder = '0' AND Status = '1'"
cmd.CommandText = sql1
rd1 = cmd.ExecuteReader()
If rd1.HasRows Then
While rd1.Read
' rd1("ColName")
'
End While
End If
'**********************************************
If Not rd1.IsClosed Then rd1.Close()
Catch ex As Exception
'Error handling code here
Finally
If con1.State = ConnectionState.Open Then con1.Close()
con1.Dispose()
cmd.Dispose()
End Try

' Do Until rs1.EOF

' Reminder_Msg = "Free Msg.Subscription Reminder.Fee:Auto renewal datedate, unless cancelled. To cancel, send STOP TT to 32132."

One difference between a Recordset and a DataReader that can be good to know, is that you use the Read() method to both advance the row pointer and check for more rows, just like you use MoveNext() and EOF with a recordset. Also you have to call Read() before you can read any data from the DataReader, it doesn't automatically read the first record as a Recordset does.

Hello Mr. Guffa,Ur solution is really a new thing for me. But I found that was not working properly for me when I test it. The following lines is not running during I execute it. But it doesn't promp me any error in my Visual Studio 2003. This is the line that it doesn't run as expected:
OriginatingAddress = reader.GetString("Mobile_No")
I put a messagebox to check the value inside Originating Address,but it show nothing inside. Do you have any idea with this? My database for this is fill will a number.
Hope to get some solution from you all here.
Thanks~!

I have an access db table with a column of type ole object. When I right click in the column a context menu displays that allows me to add an image.
Once the image is added the column displays 'bitmap image'. If I add an image via ado.net the column displays 'long binary format'.
How can I convert these existing 'bitmap image' items to 'long binary format'? The bitmap ones are causing problems with object and control references. For example I can declere a bitmap object and load from a stream as it throws an exception.
Thanks
Glenn

Let me rephrase my question.
I'm using vb.net. I'm doing the following and this exeption was thrown. ex.message = invalid parameter used.
The msaccess db table column is set to type ole object. Try this, go to the db table and right click on the column and click inser object and insert a bmp. The column value will now display bitmap image. Try your code against that and you'll experience the problem. Why?
Dim cmd As OleDbCommand = New OleDbCommand(sql, cnn)
cnn.Open()
Dim b() As Byte
b = cmd.ExecuteScalar()
cnn.Close()
If (b.Length > 0) Then
Dim stream As New MemoryStream(b, True)
stream.Write(b, 0, b.Length)
'Display image
Dim PictureBox1 As New System.Windows.Forms.PictureBox
'exception is thrown at this statement
PictureBox1.Image = New Bitmap(stream)
'ex.message = invalid parameter used.
stream.Close()
End If
'conn.Close()
Why?
Thanks,
Glenn

The links Roath gave you have nothing to do with converting an OLEObject bitmap image to a usable Bitmap in VB.NET.
I think you're looking for something more like this:
Imports System.Io
.
.
.
Dim ms As New MemoryStream
Dim oleData() As Byte = dataRow.Item("ColumnName")
ms.Write(oleData, 78, oleData.Length - 78)
Dim bm As New Bitmap(ms)
PictureBox1.Image = bm
You got the right idea, just the wrong offset when you wrote your image data to the MemoryStream.

You hit the nail right on the head. The offset was all I needed. I searched high and low for this info and could not find anything. How did you know this? Alow is their any way to test if the column value is a ole data bitmap or an image in long binary format. I may incounter both types when running the conversion.
Thanks

I've seen the code before, but I can't remember where. I thought the offset was kind of odd myself.
As for determining which type the data is, you might want to take a look at the first bytes of each type to find a pattern between the two. I think the OLE objects will have a consistent header, while the pictures might have a different header.
