    - DataGrid array Greetings, I have an array of DataGrid classes. Each DataGrid in the array needs to handle the SizeChanged event. How do I dynamically accomplish this using vb.net? In other words, how do I programmatically set a handler for each DataGrid in the array? Thanks! --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

    - Justifying Text in a RichText control I'm attempting to format rich text with C# by sending messages to the underlying richedit control. The text can be formatted by sending an EM_SETPARAFORMAT message. However, when I set the wAlignment to be PFA_JUSTIFY, it doesn't work. I know that this option only works with Rich Edit 2.0 or later version. Wouldn't VS .Net 2003 be using at least that version of the control (or newer)? Has anyone gotten this to work?

    - icons grouping with generic icon in XP toolbar I have my XP configured to group icons if there is more than 1 icon (window) associated with an application. each of my .NET forms has a custom icon for the application but when they are grouped on the XP icon they become a generic application icon (a white box with a blue strip on the top). if i click on this icon then a sub-menu opens up with each individual form *with* the custom icon correctly shown. how can i ensure then when XP groups icons that they retain the custom icon for my application ? -simon Tag: create an instance of type 'System.Attribute' Tag: 75684

    - Netadvantage Ultracombo & date time problem Hi I have this application that I am fighting with for days now. Here is the whole project; www.infovis.biz/tasks.zip. Please run and press the new task button to see what I mean. Much of the code is either form taskvision or infragistics samples btw and requires netadvantage 2004 vol2. I have the following problems with this and would appreciate any help I can get; 1. When I click in the clients field, I then click on any other field the cursor is stuck in the client field requiring an entry to be typed or selected. How can I make it so I can leave this field blank if I want to? 2. When a value is typed in the subject, details etc. fields, the time part of 'Remind date' disappears. 3. In any event, the remind date & time are not being stored properly in the tbltasks table in the access database. Not sure where in the code these values are lost even though I can see them on the screen when saving the new task form. 4. When I type a value in any field apart from client field, a 0 appears in the client field if it is blank. How can I avoid that? Thanks Regards Tag: create an instance of type 'System.Attribute' Tag: 75665

    - Process.Start problems I'm just starting to learn VB.Net (winforms) - having known classic vb for years... I was trying to build a 'dll compiler' just for grins, using the vbc.exe that resides in the DotNet Directory. I have a form that browses to that directory, and builds a string from it, adding "vbc.exe", along with the proper arguments, like this: vbcApp = txtDotNetDir.Text & "\vbc.exe" Process.Start(vbcApp & " /out:" & sFinal & " /t:library " & txtCBDir.Text) sFinal merely builds a string with a path and the name of the new dll to save - - It always stops on this line and says : An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.dll Additional information: The system cannot find the file specified I've double checked and each of the variables in the equation have valid paths/filenames and if I used it all manually at the command prompt, it would work just fine What am I doing wrong here?

    - performance problerm with custom control I have a custom control A, that has two text fields and a datagrid object. the datagrid is populated within the control, quering the information from the database at the time of construction. Now I have a Form, with a tabbed control, let's name it B. On the object B we need to display N instances of object A with all the data filled. But for some reason, any time N gets larger than 10 the program slows significantly and if we need to add 30 or more instances of A the program gets a timeout exception. Any ideas?

I have the program start 'Minimized' and I also have the program automatically start when the system starts. However, the program sits Minimized as a big block in the Task Bar (Bar at bottom with the 'Start' button). What i'd really like is to have it be displayed as just an Icon with the collection of icons over on the right in the task bar near the clock. Is there sosme simple way to do that in Visual Studio so instead of just starting minimized, it just starts as an Icon? Thanks, -- John Tag: create an instance of type 'System.Attribute' Tag: 75632

    - Sorting TreeView Hello, Standard Tree.Sorted property doesn't sort nodes like I want to. It just place them in a specific place while adding new node. This is not suitable for me, because during insertion I don't know node's name so it is placed in the end of all nodes. To make things clear I will cover some source code. Sorting works fine when I do like this: TreeNode newNode = TreeNode("Title"); Tree.Nodes.Add (newNode); This is my situation. As you see, when I add new node, I don't know its name so the sorting doesn't work. TreeNode newNode = TreeNode(); Tree.Nodes.Add (newNode); newNode.Text = "Title"; I need to be my tree sorted at any moment. Even when I change any node's name - it's place in the tree should be changed. What would you suggest for me? Is there any standard solutions or I should write my own sorting procedure? Maybe you could give me already written treeview sorting procedure? Thank you for any help. Vycka P.S. Visual Studio .Net C# P.S.S.

    - VS 2003 Designer bug? -- Duplicate declaration error Hi, I have a very simple custom control (just a button with a bitmap background). Sometimes when I add several of the controls to a form and run the app the last one or two controls appear to lose their properties and are redrawn blank at the top left of the form. I finally noticed that when this happens there's an item in the task list that says : "Duplicate declaration of member 'Font'", though the build is successful. The app runs fine (all controls in their proper place) and the .cs file is fine. It's just that the designer goes a little crazy. I've found several posts about this (mostly the same message, but sometimes with member 'Location' or 'Size'), but most people think it was just a problem with an early version of Visual Studio 2003. I've got the June 2004 version and don't have a clue what I can do to solve this. I'd appreciate any help! Especially if someone from MS could look up the error message. I tried msdn, but don't find it. To attempt to recreate copy several of the same custom control onto a form. I can usually make the bug occur when I copy/paste 12-15 instances of the control.

    - Exception Handling and Call stack unwinding Hi all, Am experiencing a problem with the Application.ThreadException event which the documentation indicates is fired in the event of an unhandled exception. It seems to be ignoring the exception handling further down the call stack - in fact it never seems to unwind the call stack at all. I am not sure if this is me doing something wrong or will that event fire in the event of any exception being raised that is not caught within the same routine or possibly even the calling routine? So the question is does the event fire before or after the unwinding of the call stack and if its before, does it stop the callstack unwinding?

    - Printing and exporting a Form or Control which spans multiple screens I want to print a Form or Control which is scrollable and only part of it is visible on the screen at any given moment. (the form may be an image, a text page and an IE browser page) Another task that I want to achieve is to save that same Form in a file (image file if it is an image, text file if it is a text) The problem is that all I know about it is that it is a Form. Nothing specific about the content. How can I achieve this? Tag: create an instance of type 'System.Attribute' Tag: 75567

    - ListView throws NativeException in Items.Insert Hello, Why does the ListView control always throw a native exception when inserting a new ListViewItem with Insert(0, new ListViewItem());? I was debugging in vc mixed mode and got an exception no matter how the function was called. It took me some time to see that this is normal behaviour for the Listview.

    - Consuming Returned Data in a WindowsForm App from a web service Hi All, I have a weather web service, if I do the following I get the data return OK as XML... Dim WeatherData As New weather.WeatherInfo.GlobalWeather Debug.WriteLine(WeatherData.GetCitiesByCountry("United Kingdom")) What I don't understand is how to consume/read the data. I presume you have to use XML classes, however my experience using xml is next to none. The example code I have seen put's the data return into a DataSet, but this won't work due to the fact the GetCitiesByCountry returns as a string...... Can any one point me in the correct direction? Thanks in advance and I hope this is the correct NG..... Wayne Taylor. www.kryptos.co.uk/blog Tag: create an instance of type 'System.Attribute' Tag: 75553

    - Win98 - Failed to load resources from resource file. Please check your Setup. Hi, I'm trying to run a Windows Forms (C#) application. It runs well on Win XP and W2K. Yet on Windows 98 we receive an error just before or while the GUI is being rendered (after displaying a splash screen, which is working on Win98). The error is 'Failed to load resources from resource file. Please check your Setup.' This error *has* been posted several times. I tried all the solution mentioned (Remove [STAThread], check if my resource files are there (the app is localized, but the resource files are there), download the needed (?) language packages, reinstall the framework,...) To no avail. The error keeps appearing. Also after reinstalling the application. We tried building a giant try-catch block to write a log about the error, but the log is never being written. We tried to use Filemon but that didn't give much information about where exactly the error occurs. The error seems to be an obvious reference to resource files missing. Does this mean that for a Win98 machine, we need to manually add some files to the program folder to make sure it will run. thanks, Vincent (Was originally posted in microsoft.public.dotnet.framework by mistake) Tag: create an instance of type 'System.Attribute' Tag: 75545

    - Smart Client I have a Windows Forms application that can run as a SmartClient. I am able to share the application .exe over a LAN by doing the following: 1) Create a reaonly share on the folder that contains the .exe 2) Have network users connect to the share and run the .exe This all works, but leaves a couple of things to be desired: 1) The share shows all the assemblies in the folder. This is kind of ugly. I would prefer that the user only see the .exe and not all the other .exes and .dlls in the folder. (Any suggestions)? 2) I would like to expose the .exe in a web page. I tried adding the .exe as a hyperlink in a web page. But when the user selects the hyperlink, they get an ugly message about how executables can be dangerous for their system. What is the recommended way to publish a Windows Forms Smart App? Can anyone point to an example of a .exe that is deployed in a web page? Thanks Tag: create an instance of type 'System.Attribute' Tag: 75538

    - VScrollBar: Must BLINK to process key hits like Home, End, Page Up, ... ???? I want a VScrollBar that does NOT blink, and still recognizes the Home, End, Page Up, Page Down, Arrow Up, Arrow Down keys. Unfortunately, the Arrow Keys will always return focus to the VScrollBar. Then, if I set focus to my user control every time the VScrollBar value changes, the VScrodoesn't recognize the Home, End, Page Up, Page Down keys. This is NUTS! There seems to be NO combination of settings that will give me normal behavior with this control. Any suggestions? Steve Tag: create an instance of type 'System.Attribute' Tag: 75534

I created a BindingListView that subclasses from ListView ... when switch to
designer mode I get ...

The designer must create an instance of type 'System.Attribute' but it
cannot because the type is declared as abstract.

Poor designer. Anyone know how I can help him out?

I don't get what your question is. Why does the designer need to create
System.Attribute instance?

Apologize if that wasn't clear ... question basically is why am I getting
this error ... and how to get rid of it?

The class isn't abstract!?!?
