    - Where is the application setting file? Hello, friends, As you know, we use application settings to store and retrieve property settings (such as window form size/location) for our application for each user. But, I could not find the file that stores all these info after running our app. (I think it should be under C:\Documents and Settings, but just could not find). Any ideas? Thanks a lot.

    - Class Finalize - how to kill a class Let's say I have a class - so to instanciate it, I put : dim cWhatever as New myClass My question is, do I need something to remove it from memory, once the form's closed? What are the recommended ways of doing this (in the class itself/in the form disposed event, or where/how)? Tag: RTF Parsing super/subscript Tag: 113671

    - Spurious internet activity in simple forms application My vs2005 windows forms program is trying to access the internet at runtime. There is no network access in my code. Could it be due to the framework or the infragistics controls? I know that at build time the framework's license compiler tries to use dns or other internet access. Could this be happening at runtime also? Tag: RTF Parsing super/subscript Tag: 113667

    - Question about DataGridView binding I have not used the DataGridView that much. I'm writing a Winforms app using a datagridview bound to a datatable. For reasons too involved to go into, the grid is not editable. When I need to edit a record, I double-click on a row and retrieve the keys as follows: key = <grid name>.CurrentRow.Cells("Column Name").Value.ToString Then do a find on the datatable and get the datarow. datarow = datatable.Find(key) Is this the simplest way to relate the datagridview and the datasource or is there something simpler?

    - When is a form disposed? (unexpected ObjectDisposedException errors) I have a multithreaded app that creates a progress form on the main thread and interacts with it from a worker thread. The code is more or less like this: void MainThread() { MyForm form = new MyForm(); ThreadPool.QueueUserWorkItem(WorkerThread, form); form.ShowDialog(); } void WorkerThread(object state) { using (MyForm form = state) { // do some work... } } So, the form can be closed manually by clicking a button on it (which sets DialogResult), or automatically when the worker thread is done and the "using" block terminates. I have written a thread-safe Dispose method, since it's called from a thread other than the one that created the form, and it looks more or less like this: delegate void DisposeDelegate(); void Dispose() { if (InvokeRequired) Invoke(new DisposeDelegate(Dispose), new object[] {}); else base.Dispose(); } My understanding is that ShowDialog() doesn't dispose the form when it returns, and indeed, Dispose() is only called once - at the end of the "using" block. The problem is that occasionally, Invoke() will fail with an ObjectDisposedException, even though it's the first time Dispose() has been called! I tried tracing through the framework with ILDASM to find the source of that exception, but with no luck. How exactly does the form know whether it's been disposed already, and under what circumstances is that flag set? Jesse Tag: RTF Parsing super/subscript Tag: 113652

    - Draw over multiple controls When a user grabs the border of an object to expand the size or move it I would like to draw a rectangle to show the growing size or changing position. The problem is that the MouseDown eevnt is within the active control, while the line I need to be drawing is outside the control. To make things worse the line to be drawn may need to "float" over other controls on the page. If I draw on the canvas of the form the line is behind the visual controls on top.

    - NativeWindow.OnShutdown is causing a StackOverflowException Hello, I have a .NET class that creates a form and displays it using ShowDialog. This .NET class has a COM visible interface that is called by the main app which is C++ COM. The form displays correctly and everything seems to be fine, but when the main app is closed I always get a StackOverflowException from NativeWindow.OnShutdown. By the time the app is closed I would think that everything regarding the .NET form has been cleaned up as the form has been closed and all related objects are out of scope. Any ideas?

    - Listbox captures focus This is very strange... I have a simple UserControl based on a System.Windows.Form. I have a databound listbox on the form, along with two radio buttons which aren't bound to anything. If I launch the form, everything is clickable. If I launch the form and navigate to any record in the listbox, I can no longer click any other control, except to close the form with the control box. None of the radio buttons are accessible. The visual feedback shows a click is occuring, but the click event doesn't fire, and despite autoCheck being enabled, the state doesn't toggle. This seems to be related to the databinding... but I can't imagine how. Anyone? Tag: RTF Parsing super/subscript Tag: 113636

    - restore from maximize When I maximize a form, it sends a resize event, which I handle. However, when I click the restore box on the form's frame, it restores the window dimensions (physically) but my resize code is not executed. I can tell it is not being called because my resize code calculates the center to display some output. What am I doing wrong? It only fails to work when I "restore down" from maximize.

    - control naming conventions, When I drag a control onto a form, visual studio gives it a dummy name. I'm wondering, what are good naming conventions you use for controls? I like to indicate the control type: for example, "submitButton" or "showResultCheckBox". Although I find this cumbersome sometimes. Also, I notice that in C#/.NET code, the m_ prefix for member variables is no longer popular, as it was in MFC. Do people use any notation to denote member variables in C#/.NET? I don't like to confuse them with local variables. Maybe it is popular to explicitly reference "this"? Tag: RTF Parsing super/subscript Tag: 113618

    - flicker in control I have made a custom control which displays a 3D object. The user can use the mouse to animate the object. However, I am getting bad flicker from the control. I call Invalidate in the mouse move handler to animate the object. I think the problem is the control repaints itself and then I draw over that myself, so it gets painted twice causing the flicker. In Win32 I would use a null brush or handle the WM_ERASEBKGND message to prevent this. Is there a flag I can set in the control to let it know I will do all the drawing?

    - Problems using CellFormatting event in DataGridView I'm writing a Winforms program in VB/Dot Net 2.0. I have a datagridview with 3 unbound fields that are filled in by the CellFormatting event handler, based on lookups using values of 3 other fields in the datagrid. Actually nothing is specifically 'wrong' but I'm wondering if anyone could give me some suggestions to improve it. First of all, performance could be better although I suspect this is in part due to a rather slow network. Any alternatives to or tweaks on CellFormatting that I might be forgetting? The actual lookup code is fairly simple. Second, I wonder if I'm making assumptions based on the old grid. I would like to hide the columns holding the lookup keys but I find if I set Visible to False, the lookup fails. The best I can do is wipe out the header text and set the column width to 2.

    - Help with form painting performance (and background images) Hello, I have a UI that I would like to build using .NET 2.0 Windows Forms. This application uses a fair number of background images & Iâ??ve found that UI performance is not very crisp, with visible repainting of the form when resizing & restore/minimize occurs. Iâ??m looking for suggestions on how to improve UI performance of the application (short of removing the background images, which does help a lot). The original application was built with a mix of .NET 2.0 Windows Form controls, DotNetMagic controls, and a few custom controls. Iâ??ve stripped out the DotNetMagic controls and the custom controls, and the performance is roughly the same. The application, which at this point is only a mockup, contains a few tabsets, some groupboxes, a number of panels, a split container, several buttons, several text boxes & quite a few combo boxes. Most of the container controls (the form itself, the various panels, the tab pages, the group boxes) have background images set, and many of the other controls that donâ??t have an explicit background image set have their BackColor property set to Transparent. At this point, what Iâ??ve tried in terms of improving performance is to ensure the BackgroundImageLayout property on all controls with a BackgroundImage set uses Stretch rather than Tile. Iâ??ve seen a few articles that suggest premultiplying images with transparency into a bitmap file should improve performance, so I tried that. For example, hereâ??s what I did for the form: public class RForm: Form { private Bitmap _renderBmp; public override Image BackgroundImage { set { Image baseImage = value; if (_renderBmp != null) _renderBmp.Dispose(); _renderBmp = new Bitmap(this.Width, this.Height, System.Drawing.Imaging.PixelFormat.Format32bppPArgb); Graphics g = Graphics.FromImage(_renderBmp); g.DrawImage(baseImage, 0, 0, Width, Height); g.Dispose(); } get { return _renderBmp; } } } I replaced System.Windows.Forms.Form with my RForm class in the form.designer file. I did the same thing for the GroupBox, Panel, & TabPage controls. I didnâ??t find any really noticeable performance improvement. Outside of the image multiplication trick above and avoiding a BackgroundImageLayout setting of Tile, thereâ??s nothing Iâ??ve done to the vanilla Win Form app. As this is a mockup, itâ??s very simple: there is no data access, nor data binding (thereâ??s no data), nor network latency issues (everything is local), the form is not set to localizable, it was built using the VS form designer, so SuspendLayout/ResumeLayout are called appropriately as the form is built. Can anyone suggest anything else I might try? Iâ??ve placed my sample VS 2005 project (does not include code that overrides BackgroundImage properties to premultiply image), along with all the images, at this URL - http://www.geocities.com/notre_poubelle/FullUITest_SlowChromeNoDotNetMagic.zip - for anyone who wants to try to speed up the performance. The slow performance can be particularly noted in two scenarios: 1. Start the app. Minimize the app & restore the app a few times. Watch the form, particularly the groups boxes (and to a lesser extent the tab pages). Please also take note of the buttons on the panel below the menu strip (the IE7 looking buttons) and the Tab control immediately below that. 2. Resize the width of the form (make it about Â½ the default size, then resize to full size; repeat); you will notice quite a bit of flicker near the vertical bar that separates the panels in the split container control (i.e. the white panel on the left and the large panel containing the â??Contact Formâ??). I would like to explore all options to improve performance (Iâ??m looking at simplifying the form as a last resort option). I would like to attain the performance of unmanged apps, if possible when restore/minimize occurs or the main app window is resized. Although Iâ??d like to improve the actual performance, if I can improve the perceived performance (e.g. by not drawing the form somehow until everything is done), I would interested in suggestions in that way as well.

    - AutoScaleMode.Font crashes program Windows Forms, .net 2.0, vs2005, xp pro. Setting AutoScaleMode.Font (or Dpi) on my main form crashes my program on some computers. If I set it to None or Inherit program runs ok. It's a very simple form with a picturebox, combobox and a slider. .net 1.1 is not be installed on at least one of the problem computers. Is 1.1 sometimes required for 2.0 apps to run correctly?

    - Weird problem with Outlook, WebBrowser control and Windows Server 2003 I have an applaction, that is an addin for Outlook. It opens a form with a WebBrowser control wich then shows a page from a Webserver. It works fine, but when I installed it on Windows Server 2003 the page didn't get shown in the WebBrowser control. I have another application wich uses the same form, but is a standalone Winform-Application. This works on both machines (my development PC with Vista and the Windows Server 2003. Does anyone have an idea, what this cuold be, or any hint where to search further? Thanks Christof Tag: RTF Parsing super/subscript Tag: 113574

    - Dataset problem with column named "System" The customer has a database with a column in a table named "System". I've been using this method for years now - create a dataset (an .xsd file) for the table. With a column named "System" in the dataset, it gives a substantial number of compile errors. To simplify the problem, add a Dataset with one table and one column called "System" - below follows how it can be done: Right click on the solution, click "Add", click "New Item" and then "DataSet" and DataSet1 is OK for the name. On the design sheet of DataSet1.xsd, right click. click "Add" and click "DataTable". Right click on the DataTable and click "Add" and click "Column". Rename the column from "Column1" to "System". Build the project = compile errors. Note that renaming the column to "[System]" rather than "System" does not work either. Tag: RTF Parsing super/subscript Tag: 113573

    - Newbie Datagridview/Combo Box problem Consider these tables: Main Table - includes StatusID (showing StatusID, integer), Status which is based on Status Table - has StatusID, and Status (varchar) StatusID is a primary key in Status table, while StatusID in the Main Table is the Foreign key of the Status ID How can I add a combobox, using a sProc to get a list of whatever is in the Status Table And then, SHOW the status (text), based on the StatusID? (in asp.net, we have a value and a text property in the Dropdownlist to accomplish this) in the combobox - I set the DataPropertyName to StatusID (which is what the DGV would bring back) and the DisplayMember to Status, but it errors out, unless I set the DisplayMember to StatusID I need it to show the text - Status - - How can I accomplish this?

    - UI Updating Hi My Windows Forms applications consists of a listview control containing of approximately 1000 items, and a worker thread that performs a lot of execution. After performing some portion of execution I update the main UI by using a delegate on the main form to call an update function on the GUI thread. However, under times of high load my GUI seems to struggle to apply the updates requested, and portions of the screen (other buttons etc) are not repainted when I resize the window. Does anyone have any ideas how I can improve the responsiveness of the main window. It is important the list view is updated as execution in the worker thread requires, whilst at the same time the remainder of the window needs to stay responsive. Thanks in advance.

    - Bummer Kevin - They deleted your ANN: Bummer - Such good postings and they already deleted them from the server. I guess MicroSquish just doesn't like the right wing wacko very much. Just FYI. Especially after he wrote to the DOJ! What an incredible stupid Putz. Oh yea, he is called Kevin Putzke. Just FYI. Tag: RTF Parsing super/subscript Tag: 113557

I'm looking for some sample code to implement super and subscript in an RTF
control w/o using the baseline offset and font size division/multiplication.
I want to actually use the \super and \sub tags from the RTF spec. Even some
open source RTF editor would be fine. Java or C++ source would even be
acceptable.

Thanks

Brian

Ok I found iTextSharp seems to do most of what I want. I'm curious if anyone
has used it to edit text in an RichTextBox. I'd like to use it behind the
scenes if possible to make the underlying RTF changes.

Thanks
