    - = nothing vs. Is Nothing Hi guys, quick sanity check please. When TESTING for nothing, it's "if <expr> Is Nothing" when ASSIGNING, it's "<expr> = Nothing" correct ? so a line "If ThisValue = nothing" in some (inherited) code is a bug, plain & simple ?

    - WinForm app speed issue Hi I have a multi-form winform database application. The client keeps complaining that application runs too slow 50% of the time. The problem seems to be in two areas; a) app is slow maximising after a prolonged period of being minimised. b) when user clicks on a toolbar to select one of the several already open forms. This seems to suggest that there is nothing wrong with application per se as application works fine 50% and also maximising app or moving from one open form to another open form does not do anything special code wise. Also as other non .net apps run just fine on the same pcs, this can't be due to spec of pcs. I have also ngen'd the app using command line 'ngen install myapp.exe'. I am therefore wondering what can be causing this slow response and would appreciate any help in ironing out this speed issue. Many Thanks Regards Tag: upload file By URL Tag: 411296

    - Split function question Hi I have written a Split function which in turn calls the standard string split function. Code is below; Function Split1(ByVal Expression As String, Optional ByVal Delimiter As String = " ", Optional ByVal Limit As Integer = -1, Optional ByVal Compare As CompareMethod = CompareMethod.Binary, Optional ByVal MaxLength As Integer = 0) As String() InAr = Expression.Split(Delimiter, Limit, Compare) End Function My questions are ; 1. Passing the Limit parameter causes a runtime error as the default for Limit (-1) is not acceptable. What is the problem? I have a feeling the syntax of split function in MSDN (http://msdn.microsoft.com/en-gb/library/6x627e5f.aspx) may be out dated. 2. How can I overloaded my split function with standard split function so I can use is as St.Split(...)? Thanks Regards Tag: upload file By URL Tag: 411273

What I found out is that I am able to trap for those files whose attribute is not Set as ReadOnly. I have done this by opening file using FileStream Object opening in Edit mode with No Shared. But if I am try to apply same logic for ReadOnly files, then it throws NonAuthorized exception. This exception is also raised even when I try to open this file even if this is not in use by other application.

    - Coding a USB connection Hi all. I have a slight issue I would like to get around if anyoine can help. I have a WM5 device running a keyboard wedge bit of software, this I've written and it works well. However I have problems with the USB device dropping off every now and then, then you have to go through the connection process again, this is quite annoying! Has anyone got any idea if it is possible to programatically create a connection to a USB device through a Com port, or do you have to use the USB connection wizard thing? If I could force the connection in code I could simply check for the connection state? Possibly? And if the expected connection isn't there, add it it? Any ideas would be greatfully received. Cheers.

    - VB.NET COM DLL form a VBScript Hi to all! I created a VB.Net COM DLL which I can use in VBScript. I followed the steps in the following article: http://msdn2.microsoft.com/en-us/library/x66s8zcd(VS.71).aspx (I used the method "with COM class template") My DLL got created fine - no errors in build process. The "Make Assembly COM-Visible" checkbox is checked. the ComClass1 class is below (dll / assembly name is ClassLibrary1): --------------begin of code <ComClass(ComClass1.ClassId, ComClass1.InterfaceId, ComClass1.EventsId)> _ Public Class ComClass1 Public Sub Importa(ByRef o As VISUMLIB.Visum) MsgBox(Marshal.IsComObject(o)) o.Net.Marking.Clear() End Sub #Region "GUID COM" ' Questi GUID forniscono l'identit=E0 COM per la classe ' e le sue interfacce COM. Se vengono modificati, i client ' esistenti non saranno pi=F9 in grado di accedere alla classe.

In caso contrario, infatti, la classe non pu=F2 essere ' registrata nel registro COM e non pu=F2 essere creata ' con CreateObject. Public Sub New() MyBase.New() End Sub End Class -----------------end of code As you can see I created a public method called Importa that accept as input a COM object from a library referenced in .NET ("VISUMLIB") Then I wrote a vbscript which creates an instance of the object: Set dllobject =3D CreateObject("ClassLinrary1.ComClass1") It works correctly! Then I put in the vbs script then statement: dllobject.Importa comobjectname The output is a msgbox with "True" (result of MsgBox(Marshal.IsComObject(o)). So the object I'm sending to the dll method is a true COM object. The problem is in the statement inside the sub: "o.Net.Marking.Clear()" I'm trying to execute the method Clear() of the container "o.Net.Marking". In my development machine everything works corretly. But I tried to install the dll (I created a setup) and when It comes to execute the statement "o.Net.Marking.Clear()" The vbscript breaks with the following error: ---------- "Unable to cast COM object of type "VISUMLIB.VisumClass" to interface type 'VISUMLIB.IVisum'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{33B2B132-69BE-4ADE-A90E-939972B93FD5}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

    - Retrieving the DefaultValue for a property from a function ..? Hi folks, I'd like to retrieve default values for properties (of a user control) via code instead of having string-constants. Consider the following (simplified) property: Private _MyColor as Color <DefaultValue(GetType(Color), "1, 2, 3")> _ Public Property MyColor() As System.Drawing.Color Get Return _MyColor End Get Set(ByVal value As System.Drawing.Color) _MyColor = value End Set End Property Public Sub ResetMyColor() '... End Sub Public Function ShouldSerializeMyColor() As Boolean '... End Function The default-value for the above prop is set to "1, 2, 3". I'd like to not have that value be specified in the property itself but rather in a different class that defines the values. Is there any way to achieve this ..? The reason for this is actually pretty simple - there is a bunch of user-controls in my ClassLib. All controls therein share a common set of colors that is to be used per default. To have all colors in a central place (in case values need to be changed) I created a class that exposes a GetColor-function and takes an enum. If anyone can come up with a better approach, I'd be happy as well! :-) Cheers, Olaf Tag: upload file By URL Tag: 411256

    - Array Problem When Index Value is Nothing Hi all, I ran into memory problems while tying to search and replace a very large text file. To solve this I break the file up into chunks and run the search and replace on each chunk. This works fine and has solved the OutOfMemory problem. However, on the last loop when the array c is written to CleanTMX, a number of 0x00 characters are written at the end of the file. This causes problems in a further XMLTransformation as this character is not allowed in XML. I looked at the values of the index. Th eproblem seems to be caused by index values at the end of the array being set to Nothing. Question: How can I get rid of these characters? Or how can I reduce the array to only contain index values that are not Nothing? Here's the code that writes the CleanTMX file: Dim c(My.Settings.ReadChunkSize) As Char 'ReadChunkSize is a user-defined setting, normally set to 10000 Using sr As StreamReader = New StreamReader(OriginalTMX, System.Text.Encoding.UTF8, True) Do While sr.Peek() >= 0 sr.Read(c, 0, c.Length) Dim i As Integer For i = 0 To arrFind.Length - 1 c = Regex.Replace(c, arrFind(i), arrReplace(i)) Next Try Using sw As StreamWriter = New StreamWriter(CleanTMX, True, System.Text.Encoding.UTF8) sw.Write(c) End Using Catch ex As Exception End Try Loop Would really appreciate any help on this one.

    - Stupid Question..Maybe I had a random thought today. Is it possible to make a complete application with several forms that contain databound info such as textboxes or dataGridViews and use 1 and only 1 dataset for the entire application? I ask because, when I created my program, for each and every form that has databound information, there is a dataset that is created. Now, correct me if I'm wrong, but when a tableAdapter, or DataTable is associated with the dataset, doesn't that contact the dataSource (ie. DB on server or remote location) during a fill(dtTableName) using excessive bandwidth? I ask about the bandwidth issue because I have an application that fills from the Products table of the database which contains over 6000+ records. I have 3 different forms that need to fill a tableAdapter from the Products table of the DB. Couldn't I just use the ONE dataset that might be Public to the entire app and grab the info from there. I understand that when changes are made and saved, then they will be saved to the dataSource which uses bandwidth but having to fill the info everytime I need to use a table from the DB takes a while to load the records. I hope to be schooled here since I mostly know about the drag and drop methods shown from online tutorials from Microsoft's Webcasts page. Unfortunately, I am using an Access DB on a mapped network drive but there has to be an easier/faster way of retrieving the data I need, right? Tony K. Tag: upload file By URL Tag: 411209

However I cannot actually invoke any functions on these tree objects. This is the current definition of TreeObject: Imports System.Web.Services <System.Serializable()> _ Public Class TreeObject Public Sub New() End Sub <WebMethod()> _ Public Sub setId(ByVal id As Int32) End Sub <WebMethod()> _ Public Function getId() As String Return 1 End Function <WebMethod()> _ Public Sub setName(ByVal value As String) End Sub <WebMethod()> _ Public Function getName() As String Return "boo ya" End Function End Class However the functions GetName, SetName, GetId, SetId do not appear in the WSDL file and the functions are not accessable from the client. (I think TreeObject has no functions other than those inherited from Object) How do I make those functions accessible please? Do I need to set up another "service" or what?

CheckForIllegalCrossThreadCalls = False Dim cnnInventory As OleDbConnection Dim dgvRow(7) As String Dim cmmInventory As OleDbCommand Dim dadInventory As OleDbDataAdapter Dim dtbInventory As DataTable Dim cmmUnitsOnHand As OleDbCommand Dim dadUnitsOnHand As OleDbDataAdapter Dim dtbUnitsOnHand As DataTable Dim intCounter As Integer, prodID As Integer 'Instantiate and open the connection cnnInventory = New OleDbConnection(My.Settings.Inventory_management_databaseConnectionString) cnnInventory.Open() 'Instantiate the command datatable cmmInventory = New OleDbCommand("SELECT * FROM Products", cnnInventory) dtbInventory = New DataTable() 'Instantiate and initialize the data adapter dadInventory = New OleDbDataAdapter("SELECT * FROM Products", cnnInventory) dadInventory.SelectCommand = cmmInventory 'Fill the data table view dadInventory.Fill(dtbInventory) 'Filter the data table view dtbInventory.DefaultView.RowFilter = "ProductIDNumber = '" & msg & "'" prodID = CType(dtbInventory.DefaultView(0).Row("ProductID").ToString, Integer) dgvRow(0) = msg dgvRow(1) = dtbInventory.DefaultView(0).Row("ProductDescription").ToString dgvRow(2) = dtbInventory.DefaultView(0).Row("ProductLocation").ToString dgvRow(5) = dtbInventory.DefaultView(0).Row("ReorderLevel").ToString dgvRow(6) = dtbInventory.DefaultView(0).Row("MinimumRequired").ToString 'Instantiate the command datatable cmmUnitsOnHand = New OleDbCommand("SELECT SUM(UnitsReceived) - SUM(UnitsSold) - SUM(UnitsShrinkage) AS UnitsOnHand " & _ "FROM [Inventory Transactions] WHERE (ProductID = " & prodID & ")", cnnInventory) dtbUnitsOnHand = New DataTable 'Instantiate and initialize the data adapter dadUnitsOnHand = New OleDbDataAdapter("SELECT SUM(UnitsReceived) - SUM(UnitsSold) - SUM(UnitsShrinkage) AS UnitsOnHand " & _ "FROM [Inventory Transactions] WHERE (ProductID = " & prodID & ")", cnnInventory) dadUnitsOnHand.SelectCommand = cmmUnitsOnHand 'Fill the data table view dadUnitsOnHand.Fill(dtbUnitsOnHand) 'Filter the data table view 'dtbUnitsOnHand.DefaultView.RowFilter = "ProductID = " & prodID For intCounter = 0 To dtbUnitsOnHand.DefaultView.Count - 1 dgvRow(3) = dtbUnitsOnHand.DefaultView(0).Row("UnitsOnHand").ToString Next Me.DataGridView1.Rows.Add(dgvRow) cnnInventory.Close() End Sub For each barcode ProductIDNumber scanned, it retrieves the description, location, unitsOnHand, minOnHand, maxOnHand. Problems: When the # of rows exceed the amount displayed, the applications seems to freeze. Example: I have a maximum of 20 rows that can be displayed at once, when I have entered 21 different items or more, then try to scroll on the vertical scroll bar, the application freezes and nothing else happens. Sometimes the scrollbar is not even displayed but instead it looks like a bunch of little grid cells. I have the properties set to show the vertical scroll bar. There is not a DataSource associated with the DataGridView. Why does it lock up when there are more rows added than displayed?? Thanks, Tony K. Tag: upload file By URL Tag: 411180

    - Objects raising events after "reinstantiation" I've run into this problem a couple of times when creating objects that raise events but I've always been able to code around it so I never asked the question. I'm using a Process object with .EnableRaisingEvents turned ON and .BeginOutputReadLine() so that I can process the output as it is generated from my process. The scenario for use is that this executable uses an .ini file that contains some settings with one of them being a path to an input file that will be scrubbed. This executable has a known issue in that only 1000 or so entries can be processed reliably during one "run" otherwise strange results occur if there are more. My use case provides that I will often have cases where I need to process 1000+ entries so my plan was to split however many entries into files of 1000 lines each and the whenever the Process.Exited event is fired when the executable finishes running, I would modify the .ini file to point to one of the other input files, re-start the process however many times I need to in order to process all my input. The problem lies in that after the first run, the Process does not raise events anymore for .OutputDataReceived but I am not re-instantiating the Process object in my class so I'm not sure why I cannot continue to capture events when I am in essence just re-starting the process with all the same properties turned on. FYI I do not have the code for this picky executable program either so please do not give any lame answers in that vein...I'm interested in how events are raised when objects die out and are re-instantiated or the context I've described above. Also I am calling Process.CancelOutputRead() in the Exited event and then calling Process.BeginOutputReadLine() after I re-start it so I don't believe this is the problem either. Thanks in advance.

    - Databind DataGridView to List(of String) I use the following code to programmatically bind a DataGridView and a BindingNavigator to various List(of myClass). This works fine with each 'myClass' offering public properties. Dim mAllUsers As List(Of myClass) mAllUsers = GetAllUsers() 'returns List(Of myClass) Dim AllUsersBindingSource As New BindingSource(Me.components) ControlStationInfoBindingNavigator.BindingSource = AllUsersBindingSource ControlStationInfoDataGridView.AutoGenerateColumns = True ControlStationInfoDataGridView.DataSource = AllUsersBindingSource AllUsersBindingSource.DataSource = mAllUsers If I change the code to Dim mAllUsers As List(Of String) mAllUsers = GetAllUsers() 'returns List(Of String) then the DataGridView only displays one column containing the length of each string. I want only to display the strings in one column. thank you very much, herbert Tag: upload file By URL Tag: 411174

    - problem with checking null or empty value in detailsview Hi, i want to check whether the textbox of the detailsview is not left empty, in insert mode. I did this: Protected Sub DetailsView1_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertEventArgs) Handles DetailsView1.ItemInserting Dim h As String h = e.Values("myfield") 'If h = "" Then If h Is Nothing Then e.Cancel = True Label1.Text = "may not be empty." End If End Sub I tried two ways (with ="" and with is nothing), but in both cases, i always get the label text and the event is always cancelled, even when i full some value. So, what's wrong with this code? Thanks Bob Tag: upload file By URL Tag: 411170

    - Moving character Glyphs I modified a C# application from Bob Powell that moves graphics primitives around on the screen into a Vb.NET 2005 application. I want to modify this application so along with moving regular geometric shapes, I can also move the alphanumeric characters as well. For example I place the character "A" on the screen and when I point to it with the mouse the character will be outlined and while holding down the left mouse button move the "A" somewhere else on the screen. Since I learn best by example I wrote another class for the Characters, but it doesn't work. I asked Bob Powell and he suggested I convert the characters to glyphs and hit test these, but since VB.NET's only resembalance to the Visual Basic programming language is in name only I'm now completely lost. Here is the Class I wrote: Public Class DrawText Inherits Primitive Public Sub New() MyBase.New() End Sub Public Overloads Overrides Sub Draw(ByVal g As Graphics) Dim b As New SolidBrush(Me.Color) Dim txt As String = "Aa" 'Dim big_font As New Font("Times New Roman", 30, FontStyle.Bold) 'g.TextRenderingHint = Drawing.Text.TextRenderingHint.AntiAliasGridFit 'g.DrawString(txt, big_font, Brushes.Black, 10, 100) 'g.FillRectangle(b, New Rectangle(Me.Location, Me.Size)) 'b.Dispose() 'Create a GraphicsPath Dim graphics_path As New Drawing2D.GraphicsPath 'Add some text to the path graphics_path.AddString(txt, _ New FontFamily("Times New Roman"), _ CInt(FontStyle.Bold), _ 80, New Point(10, 100), _ StringFormat.GenericTypographic) g.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias g.FillPath(Brushes.White, graphics_path) g.DrawPath(New Pen(Drawing.Color.Black, 3), graphics_path) b.Dispose() If Highlight Then Dim p As New Pen(Drawing.Color.Red, 3) p.DashStyle = Drawing2D.DashStyle.DashDot g.DrawRectangle(p, New Rectangle(Me.Location, Me.Size)) p.Dispose() End If End Sub Public Overloads Overrides Function HitTest(ByVal p As Point) As Boolean Dim pth As New Drawing2D.GraphicsPath() pth.AddEllipse(New Rectangle(Location, Size)) Dim retval As Boolean = pth.IsVisible(p) pth.Dispose() Return retval End Function End Class Can someone tell me what I'm doing wrong? -- Mark Tag: upload file By URL Tag: 411161

    - What is the most efficient way ... Does anyone know an efficient way to generate sound tones in Visual Basic 2005/2008 so that I can specify: - Pitch - Duration - Volume ... which uses the computer's soundcard (not the motherboard speaker).? From what I've seen, DirectX may be the only solution but even that seems extremely cumbersome. I'm amazed that Visual Basic doesn't have an easy way to do this. It was a lot easier on my Apple //c! Thanks for any suggestions. Tag: upload file By URL Tag: 411155

You never can upload a file from a client computer withouth the actions from
a user.
(Or it should be by an activeX what the user has authorisized and that he
only does in very few occassions)
