    - MDI Form question hi, I am new to winForm development. When I am using the .NET 2.0 MDI Forms, I want to close one of the child form at the very begining. For example, I want to close Form1, so I write public Form1() {this.close();} And in the MID Parent, I write form1 = new Form1(); form1.MdiParent = this; form1.Show(); The problem is that everytime I open Form1, it will close but there will be an object dispose exception unhandled and my program will hang up. Could anyone here please tell me how to solve this problem? I just want to close one of my child form. Thanks a lot! Tag: External component has thrown an exception Tag: 100875

    - RichTextBox Control Captures Shortcut Keys in Regular Windows App but Fails to Capture in an MDI App? Hello All, First, I apologize for posting this to so many newsgroups but I wasn't sure which newsgroup was most appropriate nor which newsgroup would most likely have subscribers that have done this or would have the answer. That said, below is a description of my problem: If I create a standard Windows executable in C# or VB.Net and place a RichTextBox control on the main form, the control captures standard shortcut keys as expected (i.e. Ctrl-V, Ctrl-X, etc.). However, if I add an MDI parent form to the project, make the original form a child form to this parent MDI form and display the original form, the RichTextBox control no longer captures these shortcut keys. Can someone please tell me what is necessary to correct this behavior? Thanks & Regards, TC Tag: External component has thrown an exception Tag: 100865

    - Application Settings I'm just venting. I finally got around to converting a big WinForms app for my biggest client to .NET 2.0. I've heard all along that application settings are now writable, which has always been one of many bones of contention with .NET 1.1 for me. So I get to the point where I am going to convert my custom settings mechanism, do a little investigation, and find out the reason I made a custom configuration file mechanism hasn't changed at all. Sure - you can write user setttings, and settings are type safe now, but the application scope settings are still read-only. (If anybody knows a reasonable workaround that works within the framework for this, I'd like to hear it). I certainly understand MS's reasoning for making them read-only, but I'm more of the mind that in "most cases" the application settings shouldn't/wont need to be written. However, to prevent it altogether is simply stupid, imho. I feel like I'm old enough to be responsible for my own actions by now. I do like the new stuff for user settings and for application settings that don't change, so I'm actually going to use the new stuff for all of that. However, I have one setting that all users must be able to change, and must be the same for all users. I had a custom configuration file, and I allowed write access to its containing folder on installation. I may move this value to the database for now. Or, Gawd Forbid, the Registry! Don't get me started on generic collections! Ok, I'll start, but just barely... Ha! Have you seen the Find() or Exists() method on List? Here's the code to find '6' in a list of ints: List<int> myInts = new List<int>(); myInts.Add( 0 ); myInts.Add( 1 ); myInts.Add( 2 ); myInts.Add( 3 ); int n = myInts.Find( delegate(int x) { x==6; } ); // seems rather obtuse to Find(6), doesn't it? This returns '0'! Ha! int m = myInts.Find( delegate(int x) { x==0; } ); // This returns '0' too! I tried deriving my own collection, and quickly found that two values of type T cannot be compared. I'm sure there's a good reason for this - I just hope there's a better workaround eventually. It makes me wish for the days #define! Even though that's just the tip of the tip of the iceberg of my complaints, I still like it (2.0 that is). It's definitely a step in the right direction.

    - How can I make a modeless form receive input when a modal form is open? >From my main form, I can open and access a modeless form. However, if I then open a modal form (from the main form), the modeless form will no longer accept keyboard and mouse input until the modal form is closed. Is there a way to allow the modeless form to continue to receive input? As an example, Windows Notepad does this. If you open the Find dialog, then open the About box, you can still access the Find dialog. Any pointers appreciated. Thanks, Andrew Tag: External component has thrown an exception Tag: 100850

    - Problem with no touch deployment of application which has dynamically loaded assemblies We have an application which dynamically loads an assembly and creates instances of classes. For this we have written a factory class which reflects the assembly and creates the classes and returns the created objects as plain objects. The caller method casts the object returned by the object factory into appropriate class object and uses it. All this works fine when exe is invoked directly. But when the application is deployed on the IIS for no touch deployment, the casting of the object returned by the object factory is throwing an invalid cast exception. Strange thing is that the statement that is causing exception during run time works fine if executed in the Immediate window of the VS.Net IDE. How do I fix it?

    - TextRenderer problem Hi, I'm creating a control that overrides ListView and so I'm working on redrawing everything myself with some changes here and there... But I'm having a problem with drawing the text inside the rectangle on LargeIcon mode... I thought I'd finally discovered the solution with TextRenderer but this still doesn't give the correct results. Here's the code I'm trying to use (item is a ListViewItem) Rectangle text_rect = item.GetBounds(ItemBoundsPortion.Label); TextFormatFlags formatFlags = TextFormatFlags.WordBreak | TextFormatFlags.HorizontalCenter | TextFormatFlags.Top | TextFormatFlags.EndEllipsis; if (item.Text != null && item.Text.Length > 0) TextRenderer.DrawText(dc, item.Text, item.Font, text_rect, item.ForeColor, item.BackColor, formatFlags); The problem is that its still not exactly what the original ListView displays... ie I'm displaying: ___________ | some | | really long | original ListView displays: ___________ | some really | | long text | Surely it should fit inside the bounding box if its using the GDI draw method and I'm using the bounding box thats returned to me from the ListViewItem itself?

    - Customization In Web Application All, Using VS 2005, C#.NET, SQL Server 2005, W2K3. We are developing a web application that would be shared by numerous customers for information management. Some of those customers want variations on the usual form layout. For example, we have a form where the user can enter their dependents information (parents, siblings, spouse, kids, etc.), but we know one of our customers wants to include additional information on that form that none of the other customers would use (company specific insurance coverage). Based on our experience with our C/S version of the product, we can expect to see many more requests like this. There are 3 ways to do this that I see. 1. Create a separate web application for that customer and host it on a different web server. 2. Add the custom fields to the single web application but hide the extras based on the customer using it. 3. Allow the customer to add the fields themselves and store them for just that customer. Pros and cons that I see. 1. Quick to implement, but costly in new infrastructure, and would end up difficult to maintain. 2. Still relatively quick to develop, and uses existing infrastructure, but would create complex forms. 3. Difficult to develop, but would use existing infrastructure and wouldn't need extra maintenance. Personally, I'd like to use 3. That is... Design the application so that each form includes standard fields, but a customer can add new labels, textboxes, drop-down combos, lists, etc., themselves and doing so doesn't require us to change any code or the database schema. While this would be a no-brainer in an C/S application, it gets a little more difficult in a web app since the only client they use is a browser. Any thoughts?

    - How to attach to a process middle tier for debugging Hi, I'm consulting on a project that has two solutions, a client solution, and a middletier solution. The middle tier solution is hosted in asp.net. I want to debug something in the middle tier, and I've been told that I have to attach to the asp.net process. So I add a breakpoint on the code in the middle tier. I build the middle tier solution and then the client solution in debug mode. Then I start the client application. Then I'm supposed to attach to the ASP.NET process. I've tried to attach to the asp.net process from both solutions but the debugger doesnt stop at the breakpoint.

    - Marlett not allowed? [VS 2005] I want to display a right-pointing triangle glyph like that indicating a submenu. This is "8" in the Marlett font. However, when I put a label on a form and set its font to Marlett, all I see is a regular "8", both in the designer and when the app is running. Is there a limitation? I once created a drop-down button by explictly drawing text in Marlett, and that worked, but I had to do it that way because I was using two fonts (one for the button text and one for the down glyph). I'd like to avoid doing that much work when it seems like the control should handle it for me. Suggestions? Tag: External component has thrown an exception Tag: 100794

    - Form -> Panel -> Child Form -> Resize -> Bug? I'm using the following code to show/hide a form located inside a panel that is located on my main form. The panel is set to DockStyle.Fill so that when the main form is resized the panel is also resized. The problem is that the included child form never resizes beyond it's initial starting size. Don't child forms respect the DockStyle setting during resize of parent controls? If I take out the commented lines of code it works - but of course it looks like crap while doing it. Button click event: if (f2 == null) { f2 = new Form2(); f2.TopLevel = false; this.pnl_childform.Controls.Add(f2); } if (!f2.Visible) { f2.Show(); f2.BringToFront(); f2.Dock = DockStyle.Fill; //f2.WindowState = FormWindowState.Minimized; //f2.WindowState = FormWindowState.Maximized; } else { f2.Hide(); } Tag: External component has thrown an exception Tag: 100792

    - AD Replication Problem Hello All, I recently restored two of my Windows 2003 domain controllers from a backup. They were backed up using Symantec LiveState Recovery 6.0. Everything seemed to be just fine, but just recently I noticed that AD Replication is not working. I've received Event id: 13559 Source: NtFrs. I did some research and tried what's suggested at the following link http://www.eventid.net/display.asp?eventid=13559&eventno=657&source=NtFrs&phase=1 That doesn't seem to resolve my problem, after creating the NTFRS_CMD_FILE_MOVE_ROOT file with no extension in C:\winnt\sysvol\domain, and running "net stop ntfrs" and then "net start ntfrs" I notice much diff. I did get Event Id: 13508 Source: NtFrs. Also, I can see both the servers in Sites and Services. But when I try to manually replicate i get "The Source server is currently rejecting replication requests" Does anywhere know how I resolve this issue? It's causing major issues for me and I need to figure it out ASAP. Last thing I wanna do rebuild any of the servers!

    - Problem with Waiting Form Owner I have a process that take some time to process data in formA. While processing the data I wish to pop a "waitingform". The waiting form have it's own thread and show the process advancing between 0 and 100%.There is a timer within the Waitingform, on each tick the progress percentage is read and display, also this reflect that the program is still running. When the processing finish, the waiting form just close. I have done everything and it's work well except for one thing. I wish the waiting form to be modal and own by the main form. If I set the waitingform owner : WaitingForm->Owner = FormA The waitingform doesn't appear before the data process finish, the form disappear as soon as it appear. If I dont set the owner, the waitingform works as expected, but can be lost behind other windows, and user may believe there is a problem when it's not. I use multiple threads in my application. The data processing thread is not the same as formA nor the same as the Waitingform. Does someone have an idea how I can set the ownership of the waiting form and still keep the behavior i wish?

    - Best way to organize large project I am working on rewriting a Fox 7 ODBC app. and teaching myself .NET in the process. So far I have over 130 of the screens rewritten, but debug performance is terrible. It would be much better if I had each screen as seperate solutions, but then I'm constantly having to remove and readd references which became way too much hassel. So currently my solution has the 130+ projects included. But when I start debugging it rebuilds EVERYTHING! eventhough I haven't changed a single thing!! I can play a hand of Solitaire before it finally starts executing. Not finding this situation very productive at all!!! Is there an option that can be set to only rebuild changed modules? Or has the size of my application exceeded the capability of .NET? It sure is looking that way. Or how should an application of this size be organized? The two ways I've discovered each have serious flaws and I'm seriously wondering about the feasibility of developing large application in .NET. -- Message posted via DotNetMonster.com http://www.dotnetmonster.com/Uwe/Forums.aspx/winform/200605/1 Tag: External component has thrown an exception Tag: 100759

    - Processing Enter on Form Controls I've been having trouble correctly processing the "Enter" key on form controls. Here's what I've done: Set the "AcceptsReturn" property to true Overridden IsInputKey and KeyDown; on KeyDown, if the "Enter" key was pressed, I set e.Handled to true. So now I'm receiving the event, which is good but.... When I press "Enter" in that control (it's a text box, if that makes any difference) I get the Windows "Default Beep." I don't want the default beep. Who else is receiving this event, and why is it causing the default beep? How do I stop this behavior? On a related note: I remember writing Windows software back in the day, and there were handy programs that would show me *all* of the events a particular control received...event watchers. Does Visual Studio have such a program and, if not, I assume there is something out there...if anyone has any recommendations, I would welcome hearing them.

Here's what *did* work: String[] lines = new String[textBox.Lines.Length+1]; textBox.Lines.CopyTo( lines, 0 ); lines[lines.Length-1] = textBox.Text; textBox.Lines = lines; This seems very inefficient since we're copying the *entire* contents of the text box just to add a single new line.

    - Disabled DataGridView Textbox column Hi, I am having difficulties creating a derived class for DisabledDataGridViewTextBoxColumn and cell when the VisualStyle is not supported. Basically I am down to either using ControlPaint or Graphics to achieve this. But with Graphics, I am not sure how I can make them diabled. Below are my codes: class DataGridViewDisabledTextBoxColumn : DataGridViewTextBoxColumn { public DataGridViewDisabledTextBoxColumn() { this.CellTemplate = new DataGridViewDisabledTextBoxCell(); } } public class DataGridViewDisabledTextBoxCell : DataGridViewTextBoxCell { private bool enabledValue; public bool Enabled { get { return enabledValue; } set { enabledValue = value; } } // Override the Clone method so that the Enabled property is copied. public override object Clone() { DataGridViewDisabledTextBoxCell cell = (DataGridViewDisabledTextBoxCell)base.Clone(); cell.Enabled = this.Enabled; return cell; } // By default, enable the textbox cell. public DataGridViewDisabledTextBoxCell() { this.enabledValue = true; } protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates elementState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts) { // The button cell is disabled, so paint the border, // background, and disabled button for the cell. if (!this.enabledValue) { // Draw the cell background, if specified. if ((paintParts & DataGridViewPaintParts.Background) == DataGridViewPaintParts.Background) { SolidBrush cellBackground = new SolidBrush(cellStyle.BackColor); graphics.FillRectangle(cellBackground, cellBounds); cellBackground.Dispose(); } // Draw the cell borders, if specified. if ((paintParts & DataGridViewPaintParts.Border) == DataGridViewPaintParts.Border) { PaintBorder(graphics, clipBounds, cellBounds, cellStyle, advancedBorderStyle); } // Calculate the area in which to draw the textbox. Rectangle textBoxArea = cellBounds; Rectangle textBoxAdjustment = this.BorderWidths(advancedBorderStyle); textBoxArea.X += textBoxAdjustment.X; textBoxArea.Y += textBoxAdjustment.Y; textBoxArea.Height -= textBoxAdjustment.Height; textBoxArea.Width -= textBoxAdjustment.Width; // Draw the disabled textbox if (System.Windows.Forms.VisualStyles.VisualStyleRenderer.IsSupported && Application.RenderWithVisualStyles) { if (System.Windows.Forms.VisualStyles.VisualStyleRenderer.IsElementDefined(System.Windows.Forms.VisualStyles.VisualStyleElement.Button.PushButton.Normal)) { TextBoxRenderer.DrawTextBox(graphics, textBoxArea, System.Windows.Forms.VisualStyles.TextBoxState.Disabled); // Draw the disabled text. if (this.FormattedValue is String) { TextRenderer.DrawText(graphics, (string)this.FormattedValue, this.DataGridView.Font, textBoxArea, SystemColors.GrayText); } } } else { Brush brsh = new SolidBrush(Color.Gray); Brush brFill = new SolidBrush(Color.LightGray); Pen p = new Pen(brsh,1); graphics.DrawRectangle(p, textBoxArea); graphics.FillRectangle(brFill, textBoxArea); graphics.DrawString((string)this.FormattedValue, this.DataGridView.Font, brsh, textBoxArea); } } else { base.Paint(graphics, clipBounds, cellBounds, rowIndex, elementState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts); } } } I would appreciate if anyone can point me out here.

    - how to create dynamic event handlers i'm building an desktop windows app in C#. the main menu for the application will be different depending on the admin rights of the user. i've built the entire app. in delphi and i simply activated or deactivated the menu items in that case, but all the menu items are visble. i'm hoping / thinking that with .NET, i can dynamically generate the click events for the dynamically generated menu, so that only the menu items, that a particular user has access to will show, along with their events. is this possible?

    - "line break" disapears in text box after resizing the form I put a text box on a form and set it to "multi line". I use it to show some log information. Every time there is some information, I use TextBox.AppendText method to add a information string and a "\n" into the text box. There will be a line break after the infromation string for the "\n" charactor. But after i resized the form or click some other window on the task bar and switch back, the line break disapears. All the text turns into only one single line. Is there something wrong using "\n" in multiline text box? Is there any solution for this issue? or I should use richtextbox or detail listview instead?

Hi,

I'm getting this error really sporadically in my Winforms app. Seems to
happen when trying to display a form with a call to .ShowDialog()

It doesn't seem to happen on any particular form, just pops up now & again.
I can close the application and restart it, then I can view the form without
the error?

The application is running in a Citrix terminal server environment, the
assemblies themselves are running from a network share.

Can anyone think of what would be causing this error - why is it only
happening every now & then (the worst sort of errors!)

Thanks
Dylan
