    - Form control re-build when entering the MDI container We have a huge activex control embedded in a Form window. When the Form has its MDIParent set to a mdi container, the window handle of the Form is replaced by a new one, and our control has to be InPlaceActivate twice plus one InPlaceDeactivate( The window handles of the standard controls within are also replaced ), This causes side effects to our activex control. The activation involves lengthy initializations such as downloading data from internet and heavy rendering work, so it is too expensive to do InPlaceActivate frequently. And our control has some operations depending on the parent window. Is there any workaround to avoid frequent inplace activation and window re-building, for example, creating the mdi child form directly from the MDI container? Tag: Videos Tag: 106976

    - DataGridView RowValidation Event I have a master/detail form that uses a DataGridView to show child records. I am using the RowValidating event to validate correctly entered data. As part of the validation process, I set the Cancel property of the event to true when bad data is present. This works fine as long as the master binding source remains on the current record. If the active master row changes, while a cell in the data grid is in edit mode, the form freezes. It does not redraw and stops responding to all events. The grid will still show the pencil in the row header. This only occurs if a the DataGridView looses focus while a cell is in edit mode. If no cells were currently being edited when the grid looses focus everything is fine. Tag: Videos Tag: 106974

    - Figure out how much text will fit into the form title I'm assigning a description to my form title, such as: strDesc = "This is a test if the description will fit in" frmTest.Text = "(" & strDesc & ")" If strDesc doesn't fit in the title, I don't see the closing paranthesis: ("This is a test if the description will fi..." I would like to be able to determine if strDesc will fit into the space provided, and if it won't fit, I would like display only as much as would fit: ("This is a test if the description will f...)" How can I do this? Thank you! Tag: Videos Tag: 106969

    - DataGridView performance Hi there, Has anyone had any serious performance problems with this class. A couple of hundred rows of data with 4 columns (everything loaded on-the-fly with no DB involved, all simple strings, 90% under 10 characters, the rest as high as 500-600 characters, wrapping turned on) literally takes almost 3 minutes to load on my 2.4 MHz machine (1 GB RAM with plenty to spare). Wrapping may be the bottleneck (performance improves when I turn it off) but other than using virtual mode, can anyone suggest a way to speed things up (or a reliable 3rd-party control which is really something I wanted to avoid). Thanks. Tag: Videos Tag: 106963

    - drag and drop issue... If I use software like OpenOffice and try to drag text I could notice that 1. when I drag inside the document I'm moving the text 2. when I drag outside the document I'm copying the text Yet it all looks like one smooth operation. With correct cursor feedback (the little + marker next to the icon). My problem is, once I call DoDragDrop() it's blocking, I have no other opportunities to change the AllowedEffect to only Copy if I drag over, say, an other control And QueryContinueDrag: 1. don't allow me to change the efect 2. don't inform me about the current drop target How could I do that? (i.e. how could I modify the allowed efffect depending on the target (i.e. wether it's me or not)) Tag: Videos Tag: 106955

    - Tooltip for a Listview - No Delay settings? I have crafted a routine that allows me to have my tooltip reflect which Item in my ListView I am hovering over, but I can't implement any of the delay functions. Has anyone been able to address this? I'm pretty sure I'm just missing some simple paradigm. Code: Elsewhere { ToolTip tip = new ToolTip(); } private void DisabledUserList_MouseMove(object sender, MouseEventArgs e) { Point p = Cursor.Position; p = DisabledUserList.PointToClient(p); int CurrentIndex = DisabledUserList.IndexFromPoint(p); if (CurrentIndex != LastIndex && CurrentIndex > 0) { LastIndex = CurrentIndex; //System.Threading.Thread.Sleep(1000); tip.ReshowDelay = 5000; // DOES NOTHING tip.InitialDelay = 2000; //DOES NOTHING tip.IsBalloon = true; DataRowView drv = (DataRowView)(DisabledUserList.Items[CurrentIndex]); tip.SetToolTip(DisabledUserList, drv["Path"].ToString()); } else { if (CurrentIndex < 0) tip.SetToolTip(DisabledUserList, ""); } } Thanks for taking a look and helping!

    - Clipboard Problems with HTML I'm trying to intercept the clipboard so that I can fix Word's disasterous HTML that comes through before pasting it into a text box. I just pull the fragment information from the result that comes back when you ask for the Text that's of type HTML. Everything works just great, except when there are accents: - è - è - ê - ë - à - â - ô - ö - î - ' - ? - ! - ; If you paste that into word and then paste it into a text box and intercept the clipboard I get all kinds of weird characters none of which are those above. If I leave it alone of course it works just fine. It looks like the Clipboard in .NET is not handling unicode right or something. I'm at a loss. Anyone have any ideas on how I can get the clipboard of HTML code correctly? Thanks! James Hancock Tag: Videos Tag: 106945

    - using delegates and updating windows forms Hi all: I have been playing around trying to get a progress bar to work. So far, I have the progress bar updating visibly, but the rest of the dialog now looks crappy. The rest of the dialog window badly needs a repaint, but it doesn't get one until the routine finishes that the progress-bar is attached to. I think part of the problem is that I don't understand the syntax for using delegates and threads completely. Can any one point me to a web-article on this topic, or perhaps tell me what I am doing wrong? I thought I had worked the progress-bar more or less according to the VS2005 docs. Example code follows ======================== ' blah blah.... initial code Delegate Sub UIDelegate() Sub updateUI() Me.ProgressBar1.Increment(1) End Sub Private Sub CreateBigCatalog() ' my time consuming routine ' Setup progress bar Dim newDelegate As New UIDelegate(AddressOf updateUI) Me.ProgressBar1.Value = 0 Me.ProgressBar1.Maximum = 1000 For Each title As DataRow In MyTitleTable.Rows ProgressBar1.Invoke(newDelegate) ' ..... blah blah more time consuming code .... next title end sub ----- What should I have done differently?

    - Multi-window application example Hi, I am porting an application from Windows Mobile to the desktop. This is my first .NET desktop forms application (my experience is in ASP.NET). I am looking for a sample application that employs a solid programming model for managing a multi-window application. This application has a lot of dynamiccally built forms and opens and closes forms as necessary and can have multiple forms open at once. Its very simple on Windows Mobile because all forms are always maximized and you can layer forms on top of each other with no problem. Thanks for any assistance. -Dave Tag: Videos Tag: 106910

    - Layered architecture Hi. It is often maintained, that a layered architecture is something one should consider in any nontrivial application (see e.g. Data Binding with Windows Forms by Brian Noyces). I have a VS2005 solution with 3 projects in it: 1. Adveita.UI - a WinForms executable for user interaction 2. Adveita.BLL - a library project for buisiness logic 3. Adveita.DAL - also a library project, for data access In order to achieve a full decoupling between the UI and DAL layers, I find myself writing wrapper classes in the BLL layer to present tables, columns etc. to the UI layer. Also, I am writing a lot of code to bind controls like text boxes to data and the like. I think, that the designer should be doing this for me in most cases and I that I am perhaps doing something basically wrong here. On the other hand, examples in books and downloadable samples are rather simplistic and hardly tackle questions like these. Can anyone comment on this, point out to me samples or articles addressing these questions. Regards, Gudni Tag: Videos Tag: 106908

    - Custom Form working at runtime but cannot be loaded in designer Hi, I have a custom form that works fine when I debug it or run it in release mode but cannot be loaded in the designer... Actually, it can be loaded in the designer when no control is on it, but the resizing tool (in the designer) is offset both horizontally and vertically and when I put a control on it, as soon as I save, the designer throws an exception (but cannot be reproduced everytime) and the form cannot be loaded anymore unless I remove all the controls from it... but the major problem is the offset of the designer... also, I'm unable to move the newly added controls on my form... I can resize them when I add them and after that cannot even select them... this behavior happens when I want to use the custom form (inherit forms of my projects from this form)... When I want to see the form in the designer (the CustomForm itself inherited from system.windows.forms.form) I receive and exception too (here it is) Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located.

    - Exception handling, Retry, Resume Next There are situations where you want to retry/rerun the same code again (if user wants) for unlimited times for a particular exception thrown. For example in situations like there's no CD in the drive or some file is locked by another process you want to display message dialog to user with "Retry" and "Cancel" buttons (As Windows shows "Retry" option if no CD in drive) and if user clicks "Retry" you want to run the same code again that thrown the exception. How can I construct the same "Retry" exception handling behaviour in C#. Secondly, how can I construct VB6's "OnError ResumeNext" equivalent in C# for particular exception handling. "OnError ResumeNext" actually resumes with next instruction/code if a line/code produces an exception. For example in a loop if something raised exception I want loop to continue with next iteration. How can the VB6's "OnError ResumeNext" constructed in C#. regards, Adil Tag: Videos Tag: 106895

I have written a UserControl and successfully hosted it in a web page. When this web page is displayed in IE7 the control gets shrunk to half size whenever you open additional tabs to display other pages. I think this happens because the pages are rendered at half size in the tabbed pages view. Has anyone else seen this?

    - Automatically Wrap Text in Label I have the following scenario: I have a TableLayoutPanel in my form. In one of the cells I want to place a Label control to display some text. The label might have just a few words. It might have a paragraph. I would like the label text to automatically wrap inside the cell in the TableLayoutPanel. If the row in the TLP is not large enough, it should automatically grow so that it can display all of the text. 1) I have tried setting Dock:Fill and AutoSize:False on the label. This will cause the text in the label to wrap, but it will not grow past the size of the cell in the TLP. If I set the row in the TLP to be AutoSize, the whole row becomes hidden. 2) If I set it to Dock:Top, AutoSize:False, and set the TLP row to AutoSize, this works, as long as the height of the Label is set to a value sufficient enough to hold all of the text. But if the height is not big enough, the text gets cut off. In case 2 above, it seems like I am on the right track, and that it would work if I had some way of dynamically making the Label taller depending on whether it still needed to wrap the text. Any suggestions for me on how I can accomplish this? Tag: Videos Tag: 106890

    - Switching localizable forms language messes up design I have a C# windows forms project that was designed in Visual Studio 2003. It works great. I have recently decided to upgrade to VS 2005 and .Net 2.0. I opened the project in VS 2005 and it converted it fine. I fixed the odd obsolete line of code and it compiles and runs. The problem is that my previous design was done with the systems display set to Large Fonts. My new dev system is set to Samll Fonts because this is the default setting in windows. These means I have had to go into each form and modify it slightly but that is fine. Now, my program is setup to be localizable between english(default) and french. Whenever I need to make a change to a french version of a form I just change the language in the form properties to french and boom, there it is. Now this worked perfectly in VS 2003 but in VS 2005 when I try to change the language back to english(default) after making a mod to the french version, my whole form gets screwed up. The background colour of the form and almost all of the text box properties get reset to the windows default settings. The biggest problem about this is that it is a big form with over a hundred labels and text boxes so to have to change it back all of the time can be very time consuming. I have tried everything imaginable to get it to stop doing this. I even removed the french resx file, and switched my form to not localizable, then I switch it back and re-create the french resx file, and whenever I go back to english, it is all messed up. Does anyone have a clue as to what is wrong? Unfortunately I cannot post the code for the form as it is secret in nature. Thanks in advance, Scott Tag: Videos Tag: 106879

    - Zorder and splash screen Hi, I have a form which is a splash screen. A static method is used by my main program startup to show the form, which creates the form on a seperate thread and shows it using Application.Run( splash ). The problem is when my main form shows and the splash hides, the main form ends up behind any other window display (such as my web browser or explorer windows). I've read this is because the first message pump that ends causes the application to deactivate, but I haven't been able to find a solution to this. I had replaced Application.Run with this loop: while ( !shouldClose ) { Application.DoEvents(); } Where should close is a boolean that indicates if the form should close or not. (Which is set by another static method called from the main thread). Any ideas? Tag: Videos Tag: 106874

    - Help with double-click and drag-drop Hi: I posted this 3 days ago in another V-Studio2005 group and got no replies. There seems to be better response to requests in this group. Hope nobody minds me trying for an answer here. I have windows forms .Net 2 app. in which I was using double click to activate a form. I also wanted to be able to drag items out of one form onto another. I got both working separately, but I can't seem to get them to work together. The mousedown event is trapped by my drag-drop routine. This prevents double-click. As soon as mousedown fires, the app thinks it is dragging out. The datagridview control will not accept to have both double-=click and drag-drop both as possible user-actions. Any help or ideas will be greatly appreciated. Thanks and have a great day!

    - Can Borderless forms have a context menu in the start bar? Hi I'm currently developping a skinnable form by using a borderless form (Form.FormBorderStyle=None). Is it the right way to go in the first place? if it is. Assuming that when there is no border to the form there is no context menu when you right-click on your form in the start bar too (the one with Restore, Move, Size, Close et al.)... How can I make this context menu work again? Is there a way to tell the form to make it work even if the form is borderless? thanks ThunderMusic Tag: Videos Tag: 106849

    - Window Form, Panel, can't set ZOrder at run time/design time I'm using VS 2005, .net 2.0 for a desktop application (Window Form app). I can't set ZOrder of Panel control neither at design time by toolbar/menu command "Bring to Front"/"Sent to Back" nor at run time by calling BringToFront method of panel. And Panel control doesn't support SetTopLevel method etc. I tried this while Dock=Fill and Dock=None but its not working at all. Please tell me how can I change Panel's ZOrder specially at run time, I have to show different panels at different times. Is there any way to do this or I have to set their Visible to true/false to achieve this. Tag: Videos Tag: 106823
