'prcInserting Expects parameter @Extension which was not Supplied" - Visual Basic Discussion Boards

I have a non-fullscreen and non-maximised program with a timer control that ticks over every 20 seconds performin a check on the time and comparing it to another time. It's function is irrelavent, thr problem i am having is that whenever the timer ticks over and the desktop (i.e. icons and taskbar) is visible, all the icons flash briefley and refresh. Is it possible to stop this desktop refresh when the timer ticks over.

What the code u r writing?

There is no way that a timer which does a compare of times, can cause your desktop to refresh, there's something you're not telling us.

Christian is correct. The Timer doesn't make the desktop repaint. Something else in your code is causing it.

I could post the code but at the moment its long and messy so i'll give you a run down. It compares two datetimes to check for a day, hour or minute difference using datediff. It then generates a random number and checks it against a list (of integer) to see if its been used. If it has been used it loops and generates random numbers till one pops up that hasn't been used. Then it uses the number to select a name from a comboboxobject collection.

I can't see anyway it's causing this refresh thing, but every 20 seconds (what the timer is set to) it does it, all the icons flash.

I'll post some of it:

If DateDiff(DateInterval.Day, d1, d2) = My.Settings.ChangeValue Then<br />
                If My.Settings.ChangeMode = 0 Then<br />
                    Index = RandomClass.Next(-1, Me.ImagesComboBox.Items.Count + 1)<br />
                    If UsedList.Count = Me.ImagesComboBox.Items.Count Then<br />
                        UsedList.Clear()<br />
                    End If<br />
                    Do Until UsedList.Contains(Me.ImagesComboBox.Items.Item(Index)) = False<br />
                        Index = RandomClass.Next(-1, Me.ImagesComboBox.Items.Count + 1)<br />
                    Loop<br />
                    My.Settings.Index = Index<br />
                    path = Folder & "\" & Me.ImagesComboBox.Items(Index)<br />
                    If Not path.Remove(0, path.IndexOf(".")) = ".bmp" Then<br />
                        Dim image As Image = image.FromFile(path)<br />
                        image.Save(path.Remove(path.IndexOf("."), path.Length - path.IndexOf(".")), Imaging.ImageFormat.Bmp)<br />
                        My.Settings.WasSavedAs = True<br />
                        path = path.Replace(path.Remove(0, path.IndexOf(".")), ".bmp")<br />
                    End If<br />
                Else<br />
                    If My.Settings.WasSavedAs = True Then<br />
                        Index = My.Settings.Index + 2<br />
                    Else<br />
                        Index = My.Settings.Index + 1<br />
                    End If<br />
                    path = Folder & "\" & Me.ImagesComboBox.Items(Index)<br />
                    If Not path.Remove(0, path.IndexOf(".")) = ".bmp" Then<br />
                        Dim image As Image = image.FromFile(path)<br />
                        image.Save(path.Remove(path.IndexOf("."), path.Length - path.IndexOf(".")), Imaging.ImageFormat.Bmp)<br />
                        My.Settings.WasSavedAs = True<br />
                        path = path.Replace(path.Remove(0, path.IndexOf(".")), ".bmp")<br />
                    End If<br />
                End If<br />
            End If

I need to read the contents of a file that is located in the internet. The problem is that this file is located in a folder that needs username "ukkeli" and password "hattu123". I'm using the code below:

Dim myWebClient As New System.Net.WebClient 'the webclient
Dim file As New System.IO.StreamReader(myWebClient.OpenRead("http://www.examplesite.com/subdir/file.txt"))
Dim Contents As String = file.ReadToEnd()
file.Close()

How can I make the application to give the needed username and password automatically?

it might be HTTP authentication. Try that.

I've told you three times what you have to do.

I give up. You're simply not listening, or your not doing any experimentation to test what I'm telling you.

If you don't put the effort into it, why should we?

[EDIT]
Wait a minute! Sorry! My bad. I thought you were asking the same question for a fourth time. Blush | :O

You don't need all of this:

With ComNum_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With


With ComExtension
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With

With ComCell_ID
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With

With ComActual_Extent
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With

With ComLis_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With

With ComFunc_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With

You're creating 6 seperate sql commands and adding a single parameter to each. You need to create just ONE sql command, then add all 6 of your parameters to the one command. Also, you've managed to convert the input from the textboxs to numbers, but you didn't use these numbers in the sql parameters. You, AGAIN, assigned the strings to the parameters. (This is why I thought you asked the same question for a forth time!) Those are really BAD variable names BTW.

strNum_key = Val(Trim(txtnumkey.Text))
strExtension = Val(Trim(txtextension.Text))
strCell_ID = Val(Trim(txtcellid.Text))
strActual_Extent = Val(Trim(txtactualextent.Text))
strLis_key = Val(Trim(txtliskey.Text))
strFunc_key = Val(Trim(txtfunckey.Text))

Set sqlCommand = New Command
Set prmNum_key = sqlCommand.CreateParameter("Num_Key", adBigInt _
, adParamInput, strNum_key )

Set prmExtension = sqlCommand.CreateParameter("Extension", adBSTR _
, adParamInput, , strExtension)

Set prmCell_ID = sqlCommand.CreateParameter("Cell_ID", adBSTR _
, adParamInput, , strCell_ID)

Set prmActual_Extent = sqlCommand.CreateParameter("Actual_Extent", adBSTR _
, adParamInput, , strActual_Extent)

Set prmLis_key = sqlCommand.CreateParameter("Lis_Key", adBSTR _
, adParamInput, 50, strLis_key)

Set prmFunc_key = sqlCommand.CreateParameter("Func_key", adBSTR _
, adParamInput, 8, strFunc_key)

Is there any equivalant vb.net code of the following vb6 code
Dim wp As WINDOWPLACEMENT

i was getting error .no corection was suggested.
is there any framework class whose reference is needed in my program?

This is probably a class, I doubt it's intrinsic to VB6.

WINDOWPLACEMENT is a Win32 API structure - should be available to you in .NET too... maybe you just need to import a DLL into your app.

Yes , it was an api.I just got to know.I downloaded a chunk of code from internet.I mistakenly , downloded some incomplete code.
well Thanks for the reply.

Nope - you generally have to match the structure of Win32 structs within .NET code, there's no dll that has them.

I currently using VB.NET, database is stored on sever, can i use vb.net to get database from server?
Socheat

................

in the connection string , give the path of the server

Can u give me an example?

................

If u r using MS-Access
this kind of connection string is required

dim connectionstring as string=
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\servername\d\database.mdb"

How can i get servername, if someone change server name it will automatic change, what does "d" stand for?

................

Sir,
d is the drive name (d drive) it was merely considered for an example basis.
if somebody changes the serve name then change the connection string.
simple!!! Big Grin | :-D

How come, whether the application is installed on client machine, I want to change it automatically.

................

sorry i am not getting u.Can u please explain?

I mean that i had a app and installed on client machine with network group, in app i used the server name. Example "Socheat". if you someone change server name it will automatically change so, how can i do? beside not rename server name

................

I mean that my app is installed on client machine with the server name "SOCHEAT", if someone change server name, i would like it change automatically.
