    - Suspending screen updates Hi I have a winform with a panel on it. I am doing visual changes to the panel. Is there a way to suspend screen painting during these changes? If the whole form needs its display suspended then that would work for me too. How can I do this? Thanks Regards Tag: Version Number of a an external application Tag: 411358

    - Can't sort datagrid by combo box columns I made a grid with several columns. 2 of the columns are foreign keys from 2 other tables in the datasource. I am unable to sort alphabetically by the combo box columns when I click on the column header. I think it is sorting by id not by name. How can I make it sort by name? Tony K.

    - Storing Variables I have a sub routine that's passing in a variable. I need to take that variable and store it globally...but here's what's happening. ex: I'm executing my routine: doMyThing(path, "test") I'm executing that command at least 10 times replacing the word test with my next object. When im receving that variable: Sub doMyThing(ByVal Path As String, ByVal other As String) I can use my variable...now how can I take that variable from this sub and pass it to another sub? Is there a way to store that variable or set during each call of doMyThing? Does that make sense? lol Basically I want to store it and change it during each call...i'm doing some async stuff and need it to change each time it's called.... thanks!

    - Dynamic AddressOf value for AddHandler I'm building a windows forms app in VB.net 2005 and would like to know if there is any way of adding a handler using a dynamic AddressOf value? The application will have a "Windows" menu item and I want to add a list open forms as other menu items to this list. I want to be able to do this dynamically and create a handler for each one that I add. However, instead of creating the handler everytime i open a new form, I want to use a single method that takes a couple of parameters and adds the menu item and builds the handler. an example of what Id like is shown below... Private Sub AddItem(ByVal strMenuItem As String, ByVal strMenuItemName As String) If IsNothing(Me.menuWindows.DropDownItems.Item(strMenuItem)) Then Dim oMI = New System.Windows.Forms.ToolStripMenuItem Me.menuWindows.DropDownItems.AddRange(New System.Windows.Forms.ToolStripItem() {oMI}) oMI.Name = strMenuItem oMI.Text = strMenuItemName AddHandler Me.menuWindows.DropDownItems(strMenuItem).Click, AddressOf strMenuItem & "_Click" End If End Sub Obviously I'd like to be able to remove menu items and handlers when the forms are closed using a similar method. If anyone knows how I can evalute 'strMenuItem & "_Click"' into a proper method name then I'd be most grateful. I thought that there would some some sort of Eval method that would do it, and I'm sure there is something like it, but cant remember what it is!

    - onblur in an UpdatePanel I'm having trouble with a datagrid in an UpdatePanel that includes a user control in the footer and edit rows. The user control references a js file that initializes an onblur for the textbox it contains. This is fine when the page loads however after clicking the add button, the update panel refreshes showing me the row I added and a new footer, but the code contained in the onblur function has been added to the page's javascript as if it were a validator. The problem is that at this point it can no longer reference the appropriate objects. In other words, near the bottom of my code snippets below, "doStuff(oThis.textbox);" is being placed into the anonymous javascript function at the bottom, which then throws an error because oThis is undefined. Can anyone tell me why this is happening and how to avoid it? Any I doing something wrong that is causing this? Parent Page HTML: <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <asp:DataGrid ID="Components" runat="server" ...> <Columns> <asp:TemplateColumn> <FooterTemplate> <asp:PlaceHolder ID="ph" runat="server"></asp:PlaceHolder> </FooterTemplate> </asp:TemplateColumn> </Columns> </asp:DataGrid> </ContentTemplate> </asp:UpdatePanel> Parent Page CodeBehind: Dim excip As New myUC Protected Sub Page_Init initUC() End Sub Private Sub initUC() excip = CType(LoadControl("~/myUserControl.ascx"), myUC) End Sub Private Sub Page_Load BuildDataGrid() End Sub Protected Sub Components_ItemDataBound Select Case e.Item.ItemType Case ListItemType.Footer Dim ph As PlaceHolder = CType(e.Item.FindControl("ph"), PlaceHolder) excip.Property1 = "" excip.Property2 = "" ph.Controls.Add(excip) End Sub Protected Sub Components_ItemCommand 'save info initCBO() BuildDataGrid() End Sub User Control HTML: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:Literal ID="Literal1" runat="server"></asp:Literal> User Control CodeBehind: Private Sub Page_Load If (Not Page.ClientScript.IsClientScriptIncludeRegistered(Me.GetType, "jsRef")) Then Page.ClientScript.RegisterClientScriptInclude(Me.GetType, "jsRef", ResolveClientUrl("~/myUserControl.js")) Dim sb as New StringBuilder sb.Append("dynamic javascript") ScriptManager.RegisterStartupScript(Literal1, Me.GetType(), "dynamicJS", sb.ToString, False) End If End Sub myUserControl.js: function myStuff(txtbox) { this.textbox = txtbox; this.init(); } myStuff.prototype.init = function () { var oThis = this; this.textbox.onblur = function (event) { doStuff(oThis.textbox); }; }; Produced validation code: function anonymous() { ValidatedControlOnBlur(event); doStuff(oThis.textbox); } Tag: Version Number of a an external application Tag: 411337

    - Boolean Range Hi everyone, Maybe I'm just discovering something late that everyone else knew already, but it caught me off guard. In the past I could do an expression like "If 1 <= x <= 10 Then ..." to see if x was in the numeric range 1-10. So x = 5 would evaluate to True, whereas x = 0 would evaluate to False. Well now it seems that no matter what x is, the statement evaluates to True. I can't find anything concrete to support my theory, but my guess is that the order of operations is the problem here. For example. Rather than the compiler (or whatever) evaluating the above expression as "(1 <= x) AND (x <= 10) it's evaluating it as "(1 <= x) <= 10". So if x is 5 then the first operation (in the parenthesis) will evaluate to True (or -1 converted to an integer) and if x is 0 then the first operation will evaluate to False (or 0 converted to an integer). Either way, once the second expression is evaluated, you will always get True, sinse "-1 <= 10" and "0 <= 10" both equate to True. Anyway, sorry for the long winded example, but is my theory correct? If so, then I would assume that the best way to achieve what I need is "If 1 <= x AndAlso x <=10". To be honest this situation doesn't come up that often for me, so it could be that the last time it came up I was using a language with different syntax rules like C# or C++.

    - Dim lblTimeleft As Label = CType(e.Row.Cells(9).FindControl("lblTimeleft"), Label) Hi guys, I'm a bit of a newbie, but know VB Classic quite well. The above statement appears in some code I'm hacking, and I have added a column to the DataGrid (in the middle, so those to the right have had their index upped by one). Yet the statement above seems to still return the same value. Is the Index value (9) in the statement : CType(e.Row.Cells(9).FindControl("lblTimeleft"), Label) doing anything, or is the call simply going to the row, and picking the control from there ?

    - Activate Event Equivilent for UserControl? Hi, I have Windows Form with several User Controls embedded within. Only one user control is visible at any one time. The user moves through the various user controls by clicking Previous and Next buttons. What I want to happen is for the individual user controls to have the ability to set focus to a specific textbox control when the user control becomes active. Normally I would handle this sort of thing via a form's activate event, but user controls do not have this equivalent I've tried the GotFocus and Enter events as well but neither fires independently simply when the user control becomes the form's focus. Right now I have the textbox focus working - but only through calling it via the parent form (the parent form causes the user control to come to the forefront, then sets the focus). But I'd rather have the logic self contained within the user control. Is there some sort of Activate event equivilent for user controls?

    - 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: Version Number of a an external application Tag: 411296

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?

    - 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: Version Number of a an external application Tag: 411256

    - SerialPort class and timeout Hi all, i'm in a trouble handling timeouts of the SerialPort class. If I set timeouts (<>0) what i have to expect? An error? A call to DataReceived routine? A call to Error routine? What is the initial moment when the timeout count starts? When i open the port? When I send data? Delay between chars? What is the 'real' minimum timeout the code is able to handle? What about 5 ms?? Thanks! -- SteM Tag: Version Number of a an external application Tag: 411235

    - Why does CLick once insist on .net 3.5 Hi, I have a basic app that I have build and am trying to use the click once/publish feature to make the installation. I have create a Virtual Machine using XP SP2, install VS.2005(aka dev) and created the project. I have a second Virtual Machine also with XP SP2(aka Clean), nothing else installed. When I use the Clean machine to run the installation it first wants to to install dotNet framework 3.5 I don't want to have the user having to install 62mb of .net 3.5 framework when the application is build for 2.0 I have checked the setting for the publish now function, and the only Prerequisite is .net framework 2.0 Even when I unclick this (to test) the application installation still wants to install .net 3.5 framework. What is going on!!! I want to have XP Sp2 users using my applicaton, so since they already have 2.0 then I don't have to install anything but my little application Tag: Version Number of a an external application Tag: 411233

    - 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.

    - Writing a simple webservice Hi guys, I'm looking to develop a simple web service in VB.NET but I'm having some trivial issues. In Visual Studio I create a web services project and change the asmx.vb file to this: Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel <System.Web.Services.WebService(Namespace:="http:// wwwpreview.#deleted#.co.uk/~ptaylor/Customer.wsdl")> _ <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <ToolboxItem(False)> _ Public Class CustomerService Inherits System.Web.Services.WebService <WebMethod()> _ Public Function getCustomer() As TreeObject() Dim t1 As New TreeObject Dim t2 As New TreeObject Dim t3 As New TreeObject Dim arr(2) As TreeObject arr(0) = t1 arr(1) = t2 arr(2) = t3 Return arr End Function End Class As you can see my function returns an object of type "TreeObject" and when you run this it works. the clients are clearly returned an array 3 TreeObjects objects. 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?

Hi Ryan,
=2ENET provied easy access to a process's version info using
FileVersionInfo class located under System.Diagnostics namespace.

For example, you can get file version:
Dim info As System.Diagnostics.FileVersionInfo
info =3D System.Diagnostics.FileVersionInfo.GetVersionInfo("c:\rich-text-
editor.exe")
MsgBox(info.FileVersion.ToString)

Look at other properties and method members under
"System.Diagnostics.FileVersionInfo" to get more info about process's
name and version info.

Hope this helps,

Win32 version resource:

'FileVersionInfo'.

Assembly version number:

'Assembly.Load*', 'Assembly.GetName', 'AssemblyName.Version'.
