    - Error on adding items to toolbox Hi all, I'm trying to add items to toolbox from my dll. In Choose Toolbox Items dialog->.NET Framework Components->Browse I'm selecting my dll to add my windows forms controls => and always it gives me an error :"Microsoft Visual Studio 2005 has encountered a problem and needs to close". Of course I'm sending the error report to Ms, BUT where do I find more info about what it is wrong with my dll ??? Error details don't help me at all and Debug button seems it is not working. I found 2 errors in Event viewer-Application: 1. Microsoft Visual Studio : Event Type: Error Event Source: Microsoft Visual Studio Event Category: None Event ID: 1000 Date: 1/9/2006 Time: 5:24:36 PM User: N/A Computer: CIMS2005 Description: Faulting application devenv.exe, version 8.0.50727.42, stamp 4333e699, faulting module ntdll.dll, version 5.1.2600.2180, stamp 411096b4, debug? 0, fault address 0x0001142e. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. 2. .NET Runtime 2.0 Error Reporting :Event Type: Error Event Source: .NET Runtime 2.0 Error Reporting Event Category: None Event ID: 1000 Date: 1/9/2006 Time: 5:29:36 PM User: N/A Computer: CIMS2005 Description: Faulting application devenv.exe, version 8.0.50727.42, stamp 4333e699, faulting module ntdll.dll, version 5.1.2600.2180, stamp 411096b4, debug? 0, fault address 0x00010e03. And, of course, no Additional info about this issue at Help and Support center. It is almost the same dll that I was using SUCCESFULLY in Visual Studio .NET 2003, but, of course, now is fully recompiled in VS2005 (.NET Framework 2.0)with minor changes. It is a pretty complex dll, with many controls. Basically, my windows controls are inherited from System.Windows.Forms. TextBox, ComboBox, ... + custom properties and methods, nothing else. I have Visual Studio 2005 Team Edition for Developers + Windows XP SP2 installed on a clean computer. I'm getting the same error on a diferent computer. How can I find what it is wrong with my dll ?? Thanks for any advice. Tag: ListView ownerdrawn headers Tag: 96313

    - XSL Transform in WebBrowser control Hello, The new WebBrowser control in .Net 2.0 is great... does anyone know how I can view an xsl-transformed xml file in it? Ideally I'd set the XML file, set the Xslt file, and then view the result. The xml file does not initially have a reference to the Xslt file. Thanks, Mark Tag: ListView ownerdrawn headers Tag: 96306

    - Form.Closing Event fired on Minmize Hello All, I have a modeless child form displayed on top of an owner form. I am seeing the strange behavior of the modeless form's Closing event being fired in reponse to the minimize button being pressed on the owner. Pressing the minimize button of the child works as expected however. The only messages I see received after pressing Minimize and before entering the Closing event handler are: WM_SHOWWINDOW (SW_PARENTCLOSING) WM_SHOWWINDOW WM_SHOWWINDOW WM_WINDOWPOSITIONCHANGING WM_WINDOWPOSITIONCHANGED WM_WINDOWPOSITIONCHANGED WM_SHOWWINDOW I am at a compelete loss on this one, though as usually, it's probably something simple. Thanks. Tag: ListView ownerdrawn headers Tag: 96302

    - Form.WindowState question I want to cause a form to come to the top of the z Order when it is notified by another task (i.e. I want it to be right under the user's nose, not having its title bar blinking on the task bar). If the window is minimized at the time, then WindowState = FormWidowState.Normal works perfectly. However, if the window is not minimized, and it is covered by other windows on the user's desktop, then I can not get it to come to the front except by: WindowState = FormWidowState.Minimized WindowState = FormWidowState.Normal. Is there a better way of doing this? Thanks in advance. Tag: ListView ownerdrawn headers Tag: 96301

    - Mutex... I hope this is right forum for this... I have the below block of code in my Main. When I compile in debug mode, I get to run one instance only. When I compile in release mode, I get to run more than one instance of my application. These are the first lines of my application.. I tried to set the mutexName to a string or a GUID or the full assembly name, still I can't get single Instance behaviour in Release mode bool mutexWasCreated = false; bool requestInitialOwnership = true; string mutexName = "MyApp"; //System.Runtime.InteropServices.Marshal.GetTypeLibGuidForAssembly(System.Reflection.Assembly.GetExecutingAssembly()).ToString(); //System.Reflection.Assembly.GetExecutingAssembly().FullName; System.Threading.Mutex m = new Mutex(requestInitialOwnership,mutexName,out mutexWasCreated); // If I put a log information here. I get True also.. try { if (mutexWasCreated) { m.ReleaseMutex(); } else { MessageBox.Show("Application is already running","MyApp",MessageBoxButtons.OK,MessageBoxIcon.Error); return; } } finally { m.Close(); } // Code here calls Application.Run Tag: ListView ownerdrawn headers Tag: 96300

    - vs2005 - Why all the errors? yet the code works. Hello, >From time to time my vb2005 form disappears and is replaced by the following errors. Rebuilding the application never helps. However the errors never affects the operation of my application that I notice, but it is very anoying. To get rid of the errors I must close the form, close the application and then reopen it. \\\ One or more errors encountered while loading the designer. The errors are listed below.

    - prompted for username/pw when accessing no touch deployment app on Win2K3/IIS6.0? We are moving from a Windows 2000 Server to a Windows 2003 server. Our ASP.NET web applications work fine on IIS 6.0 on the Windows 2000 and Windows 2003 server. All of our no touch deployment .NET Windows applications work fine on Windows 2000 server but when we move them to Windows 2003 Server / IIS 6.0 the following happens: 1) User access the EXE via URL... (ex: http://new2k3webserver/somefolder/someapp.exe) 2)User is prompted to enter user name and password 3)User can click cancel and the application will run normally, or user can type in their domain account information and the application will run normally. This is a big nuisance. Does anyone have any suggestions. This happens with out most complex applications and our simple applications. As a test, I wrote a .NET 1.1 WinForms application with no lines of code and only a Form at start up and the same problem occurs when I post it to Win2K3 / IIS6 as a no touch deployment app. All suggestions welcome.

    - Binding class properties to controls with cancel to prevent editing Hi, i am very new to data binding and am a little confused! I have some properties in a class which i would like the user to be able to edit. I can bind these fields to a control and then show the form, the user can edit the data in the text boxes and the class's data members get set ok without any problems. I do however want to have ok/cancel buttons on the form, which if the user clicks cancel all changes will be forgotten. now my problem is with the binding scheme i am using it seems the class's member data gets set when the text box control looses focus. I would like to hold of any changes until the user hits ok, whilst at the same time keeping the capability to check that data entered is valid and within allowed bounds. I can always create a copy of the class, bind the form controls to that class, then check the form result when it returns from being shown and if i get a DialogResult.OK assign the settings to my class, however im not sure i can do this as i have socket members etc that will overwrite my current socket and likely kill the connection which is not what i want. another way is to keep the class's settings in a seperate structure and bind that however to me that seems messy. Is there not a nicer way to achieve this??! Sorry for the newb question, i have spent a long time searching for an answer and im totaly stuck. Is data binding even the correct thing for me to use? Any help much appreciated. Chris Tag: ListView ownerdrawn headers Tag: 96292

    - Can not connect to Access 2003 DB via Jet.Oledb.4 I have a VB .Net Windows application that accesses an Access Database using ADO.Net OleDB .Net Data provider. Users are running Windows XP with the .Net Framework installed. It works fine on user's PC who have MS Access installed. However, when I distribute this to a user who does not have MS Access installed, the program cannot open the connection. The database and the executable are on the same machine and I install the Access 2003 runtime on the client machine. The Access database contains tables only. The users will not access the database directly. All IO is done thru the VB.Net application.I have a license to distribute Access runtime, but do not want to do so if all I need to do is set a reference to Jet (or some other dll) so that the required files are included in the installation package. Is there some reference I should set before deploying?

    - HTML -> Smart client (communications) I need to tie together two apps; a thin (HTML) client and a smart-client (running on the user's machine) deployed with click-once. My question is: does anybody know of a good way to communicate between the two? The thin client is HTML generated from an asp web-site (not asp.net) [can easiy be edited as required] The smart client is C# / win form / .Net 2 The user is not an administrator, and ideally few or no changes would be required Must also work on internet zone to support extranet usage Current ideas: 1: HREF to a second .application with params on query-string; this exe accepts the params and uses remoting to talk to the main exe (and then exits) 2: (preferred option) Smart-client starts up a simple web-server (e.g. HttpListener or similar); thin client posts to http://localhost/somewhere?someparams [problem: this triggers cross-domain security warnings; don't want to have to trust the web site] 3: Some kind of control embedded on the page? Not sure if this can be deployed easily? (don't want COM overhead) 4: other? At the minimum I need to be able to send data in the forwards only (html->smart) direction. Being able to process the response would be a "nice to have". I do not need to be able to push from the smart-client to the web page (thankfully). Any suggestions? Surely somebody has had to do something similar? Many thanks in advance, Marc Tag: ListView ownerdrawn headers Tag: 96265

    - Activating a message box in .NET I have a .NET 2.0 form that parents a message box. Neither is currently active. How can I programatically activate the message box? I can't seem to do it via the .NET Framework, since message boxes aren't .NET forms, so I've tried doing it via the Win32 API, but still no luck. Here's what I've tried so far: // First activate the parent form parentForm.Activate(); // Now attempt to activate the message box itself const int GW_CHILD = 5; const int WM_ACTIVATE = 6; const int WA_INACTIVE = 0; const int WA_ACTIVE = 1; int hwndParent = (int)parentForm.Handle; int hwndMsgBox = GetWindow(hwndParent, GW_CHILD); if (hwndMsgBox != 0) { SendMessage(hwndMsgBox, WM_ACTIVATE, WA_ACTIVE, hwndMsgBox); SendMessage(hwndParent, WM_ACTIVATE, WA_INACTIVE, hwndMsgBox); } Regards, Marcus Ogden Software Development QSR International Pty Ltd Tag: ListView ownerdrawn headers Tag: 96259

    - Capture Form Move - Start and Stop Hi, I want to capture the move of a form with an override of OnMove, which works fine. But I want to register also when a user starts moving a form and when he releases it, any idea how to accomplish that? Here is what I tried so far without success: - Capturing the OnMouseCaptureChanged: As the Capture flag is set during the form move and is unset after, I expected this event to be fired, but it isn't. So it does not help... - Overriding WndProc and capturing WM_NCLMOUSEDOWN, WM_NCLMOUSEUP, WM_LMOUSEUP: To register the mouse down in the HTCAPTION and the mouse up as the end of the dragging of the form. I receive the nc mouse down event, but I never get a mouse up, except if the form is maximized. No idea, why that is... the form has a sizeable toolbar frame. Anybody any other ideas?

    - Embedded win forms: focus/tab control problem I am "embedding" several Winforms (Form descendants) in Panel controls, showing them as follows: this.TopLevel = false; //this is a Form this.Parent = parent; //parent is a panel this.FormBorderStyle = FormBorderStyle.None; this.Dock = DockStyle.Fill; this.Show(); The "embedded" forms are shown correctly in the container panels, but focus/tab control does not work as it should. Once you tab into the first "embedded" form, further tabbing will move the focus from one control to another only inside this "embedded" form, never releasing it to the next one, or to any controls of the container, top-level, form.

    - DataGridView Validation Problem! I have implemented a custom date control; it's a UserControl containing a MaskedTextBox control. I have created a DataGridView custom column using this UserControl. DataGridView is very demanding of its custom column controls. But I have finally modified the UserControl so it mostly works correctly, except for one major problem. When a cell loses focus (via tab, enter, etc.), the DataGridView gets the control's value (via a get of EditingControlFormattedValue) BEFORE the MaskedTextBox raises the TypeValidationCompleted event. Since the app is required to prevent leaving the UserControl unless there is a valid date value, the app does not expect to be able to retrieve an invalid value. But since the validation occurs too late when in a grid, the value is retrieved before it is ready. To make a long story short, this appears to be a serious (at least for many uses) bug in the DataGridView. Trying to have the UserControl do special validation in this case leads to some pretty convoluted logic! Can you suggest any clean way to prevent this problem from occurring?

    - ListView ownerdrawn performance Hi all, I've been testing a listview control on an app I'm creating which is in 'details view' with 3 columns. It can contain string information from 4 different objects (linked with Tag), each drawn with a unique colour. When I load in 2000 (or even as low as 500) objects the performance hit is quite bad, I had to derive a new control from ListView so I could enabled double buffering on the control. This stops the flickering, but there is a noticeable lag when scrolling the vertical bar up and down. Even having as few as 200 objects displayed creates a slight lag. At first I thought this might be due to me using many different colours, so I tried redrawing in just one colour and the same thing happens. What looks worse is minimising the form, and then restoring it, the listview doesn't draw (so the desktop can be seen through it) for a few seconds (I guess it's drawing the contents of the listview during that time). If I turn off ownerdrawn there is no lag on drawing even 2000 items, although there is a few second delay on loading the items. Is this performance hit normal for ownerdrawn listview controls? If not, any tips on removing it would be appreciated! Chris Tag: ListView ownerdrawn headers Tag: 96248

    - ToolStripComboBox binding problems The following code only "binds" when the toolStripComboBox1 is at the top of the toolStrip1 hierarchy (i.e., ToolStrip > ToolStripSplitButton > ToolStripComboBox). Why will the control NOT bind when it moved (recreated) as a child control of a toolStrip control (i.e., ToolStrip > ToolStripSplitButton > ToolStripComboBox)? I have also tried casting toolStripComboBox1.Control as a standard ComboBox and binding it that way. That method produces the same effect. I can use the exact same binding settings on a regular ComboBox with no problems either. The problem truly seems associated with the fact that the control being bound seems to be nested. //(bsCustomers is a BindingSource object and dvCustomers is a DataView object) bsCustomers.DataSource = dvCustomers; toolStripComboBox1.ComboBox.DisplayMember = consts.Columns.colCustomersName; //"Name" toolStripComboBox1.ComboBox.ValueMember = consts.Columns.colCustomersID; //"ID" toolStripComboBox1.ComboBox.DataSource = bsCustomers; ------------------------------------------------------------------- Versions Microsoft Visual Studio 2005 Version 8.0.50727.42 (RTM.050727-4200) Microsoft .NET Framework Version 2.0.50727 Installed Edition: Professional Microsoft Visual Basic 2005 77626-009-0000007-41501 Microsoft Visual Basic 2005 Microsoft Visual C# 2005 77626-009-0000007-41501 Microsoft Visual C# 2005 Microsoft Visual C++ 2005 77626-009-0000007-41501 Microsoft Visual C++ 2005 Microsoft Visual J# 2005 77626-009-0000007-41501 Microsoft Visual J# 2005 Microsoft Visual Web Developer 2005 77626-009-0000007-41501 Microsoft Visual Web Developer 2005 Crystal Reports AAC60-G0CSA4B-V7000AY Crystal Reports for Visual Studio 2005 Tag: ListView ownerdrawn headers Tag: 96246

    - RichTextBox formating problems Hi, I have a richtextbox which I have modifyed to enable scrolling (ie text gets added to the bottom and gets scrolled upwards when new text is added). I have also modifed so that cirtan text can be a different color using the SelectedStart, SelectedLength and SelectedColor properties. This is all working fine. Now I want to limit the amount of text which ends up in the display so I'm using the string.Remove function to remove text from the begining of the text. However in doing an kind of operation to remove text all formating is lost on my current text. This sucks!!! So I tryed implimenting a solution which stores the formating applied to the text. This is very slow and also sucks. Basically I need a better way of a: removing text from the text box without loosing formating b: a way of capturing previously formated text and reappling it to new text c: appling my own method of storing formating to text Thanks Tag: ListView ownerdrawn headers Tag: 96239

    - How to see current windows message queue My form gets a resize message after completing a button click event and I cant find the source of this resize message. My button event makes same calls to directx device and resizing or maximizing the form. Yes these calls can be source of the unknown resize event but I see my resize event raised at the moment doing these calls in the button event. After finishing all calls and resizings in the button event, I get a resize event, but from where ???? I look to call stack at this resize event, and I cant see and code of mine raises this event. So I think a line of code in the button event creates a resize message in the message queue for processing it in the App.DoEvents call. not in the button event. And this message waits the current button click message ending. I will give a code example : method MyForm.ButtonClick // this is the event method of my button [ // in this event, we make lots of calls backup form's size (*) reset directx device restore form's size (*) .... // I think one line of code in this event, adds a resize event to message queue to process later ] method MyForm.Resize // resize event [ // this event raised at the moment of running (*) lines some code... ] after completing the button event and before returning to normal program loop, I get an extra resize event :( :( so, I need to see all stored messages in message queue when I process my button event. for example, I will print the current message queue status to console line by line in the button event. I really need to see which line of code adds the f..king extra resize event to the queue. pls help me, how can I get the current windows message queue status to print to console Tag: ListView ownerdrawn headers Tag: 96233

    - Controls paint slowly Sorry for re-posting in this newsgroup - but this group is more apropriate than dotnet.general I am developing a mdi application that will act as a front end to a database. I am finding that when i show any of the mdi child forms in my application it is noticeable that the form is shown first with the areas where the controls will be displayed cut out and what ever is top most before the form is shown is momentarity seen through these areas. This is also noticed if the user changes focus to say internet explorer and then back to the running application. I find that this is more noticeable for textboxes, labels and toolstrips but not listboxes or tab controls. I have tried various methods suggested for double buffering, however these appear to show no signs of improvement. None of my mdi child forms are currently doing anything special on loading - the form as seen in the form designer is just being shown (no data access on load) I would appreciate any suggestions.

    - How to make controls expand to fill screen in fullscreen mode I design my forms in Visual Studio, which has limited screen space for the form. After compilation, I run the project and expand the form to fullscreen mode, but the controls and other elements on the form remain fixed -- they don't expand to fill the entire screen.

    - A Framework for Datadriven Forms for VB Dot Net Hello All, I am currently in the middle of creating a 'Framework' for my latest VB.Net project. I have always created such a tool for previous lauguages. This time I am basing it on n-Tier architecture. I will probably continue and develop my own version, but have any of you people developed your own version, or used and 3rd party tools. What I am referring to is a set of code that can be used for most forms in the application, they will display data, allow for additions, deletions, updates, will support record selection, etc. I typically then add error logging, application logging, and a few other minor features. The only problem is it is a little labourious creating all the code for each layer, and the stored procedures required, and the stored procedures for the combo's also. I am attempting to use .Net 2003's data adapter to generate some of the sql for the updates and deletions, but I still have to hand write a reasonable amount of the code myself. Any thoughts? Thanks in advance Mark Breen Ireland Tag: ListView ownerdrawn headers Tag: 96189

    - Window with another window on top of it. I have a situation where I have a window and I want to put another window on top of it that opaque at 50%. That works fine. But I'd also like to have it that when I move the main window, the opaque one moves with it. How can I do this? Do I need to go to an MDI which I really don't want to. Or do I have to move the opaque window in the main window's Move event? TIA - Jeff. Tag: ListView ownerdrawn headers Tag: 96187

    - using console with a windows app I have a VB app with a form under FW 1.1, sp1. In sub main, I do some setup processing that may or may not result in some calls to: Console.Writeline(...) eventually, I do: Application.Run(New Form1) All this works. If the app is run by clicking the app's icon, the console writes are discarded. If I run from a command prompt window via app arg1 arg2 | more I will see the console writes in the command window. But if I run via app arg1 arg2 the console writes are discarded. I would like to avoid piping to 'more' if possible. I guess what I want to do is flush and close stdout before I do Application.Run(New Form1). But Console.Out.Flush() and/or Console.Out.Close() don't help. I'm looking for a .net solution - not api's. Also, I have read some info about making a console app and starting forms from it. I'd rather not go that way - this app is a windows gui app that has a couple of troubleshooting command line features. So, is there a .net way to close and flush stdout so the text is visible in the command prompt window while the windowed app continues to run? Tag: ListView ownerdrawn headers Tag: 96185

    - Can't Read App.config with No-Touch Deployment and .NET 2.0 My application uses the no-touch deployment model. In .NET 1.1, this works great. After I installed .NET 2.0 (and subsequently uninstalled it), the application can no longer read the app.config file. Example: ConfigurationSettings.AppSettings.Get(...) always returns Nothing. Again, this works with 1.1, but not with 2.0 (tested on mulitiple machines). Any insight? Thanks in advance, Rob Tag: ListView ownerdrawn headers Tag: 96183

    - migrate project from .net 1.1 to 2.0 Hello, I'm developping a program for over a year now and this is based on the framework 1.1 Release date is scheduled by the end of this year and I wish use the framework 2.0 I figure the sooner the better. I have installed vs2005. This nicely converts my vs2003 projects and solutions to the new version. But I think it still uses the framework 1.1. What do I need to do to make it use framework 2.0. Without a lot of trouble (or work). I think I could always recreate every project and then import the files, but I think there should be an easier way. Maybe setting a property or so on the project or whatever. Best regards, Ike Castelyn Tag: ListView ownerdrawn headers Tag: 96178

    - How does Resource Manager work? Hi, I want to know how the Resource Manager works. In particular, how the resx file is created when we design a form. Wat goes into the resx file. And how does the ResourceManger use this resx file at runtime to show the form etc. Any good material on this topic? Sinex Tag: ListView ownerdrawn headers Tag: 96175

Hi all,

How would I go about mimicking the system drawn clickable style when
ownerdrawing the column headers? I.e. the mouse over changes the column
headers colour, and clicking it changes its style.

Any help would be appreciated.

Just incase anyone ever googles this, the answer is to simply:

e.DrawDefault = true;

in the column header draw
