    - Saving and restoring Windows form states I'm developing a windows form application which allow users to query the database. When users press the reset button, the windows form will go back to the initial state(resetting all the controls in the windows form to initial state) I've thought of the followings to achieve this 1) Put all the resetting codes inside the reset button event. 2) Use serialization 3) Close the windows form and create a new windows form. But I think there may have some better ways.Can anyone advise me Thanks Tag: Windows Forms Designer Implementing SnapLines at RunTime Windows Forms

    - MDI and OutOfMemoryException Hi, I have this code that makes the form as an MDIChild: chartWindowController.GetForm().MdiParent = _expertTradeMainFrm; chartWindowController.GetForm().WindowState = FormWindowState.Normal; chartWindowController.GetForm().Show(); The above code snippet throws exception when Show() is called: Message "Object reference not set to an instance of an object." StackTrace " at System.Windows.Forms.ToolTip.CreateHandle()\r\n at System.Windows.Forms.ToolTip.get_Handle()\r\n at System.Windows.Forms.ToolTip.WmWindowPosChanging(Message& m)\r\n at System.Windows.Forms.ToolTip.WndProc(Message& msg)\r\n at System.Windows.Forms.ToolTip.ToolTipNativeWindow.WndProc(Message& m)\r \n at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)\r\n at Microsoft.Win32.SafeNativeMethods.MessageBox(HandleRef hWnd, String text, String caption, Int32 type)\r\n at System.Diagnostics.AssertWrapper.ShowMessageBoxAssert(String stackTrace, String message, String detailMessage)\r\n at System.Diagnostics.DefaultTraceListener.Fail(String message, String detailMessage)\r\n at System.Diagnostics.DefaultTraceListener.Fail(String message)\r\n at System.Diagnostics.TraceInternal.Fail(String message) \r\n at System.Diagnostics.Debug.Fail(String message)\r\n at CimsFramework.CimsSecurity.CmsUsrDataSheetSubModule.GetDataEntryInfo() in D:\\CIMS.NET\\CimsFramework\\CimsSecurity.cs:line 4127" But when the same is not a MDIChild then it works fine i.e., if I comment the line chartWindowController.GetForm().MdiParent = _expertTradeMainFrm, then the application works fine. I have Visual Team Edition 2005 for Developers + Windows XP Sp2. Can anyone let me know why this is happening or how to fix it. Thanks in advance.

    - Draw on another display I have an application in which I would like to play a video in full screen on another display. I am able to list all connected display devices using the System.Windows.Forms.Screen class, and I have no problem playing a video in full screen using Microsoft.DirectX.AudioVideoPlayback.Video. However, I am unable to figure out how to display this on another monitor. I am fully aware that I will likely have to create a form on the second display and play the video from there, but as far as I can tell there is no way to do this from the Screen class.

    - GDI+ button image painting problem I agree with Philip, creating a GraphicsPath from the pixels of the bitmap should be brutally slow, both in creating the path and rendering it with DrawImage().

    - DataGridView.CellValidating event problems I am having many problems with the CellValidating event. In many cases while editing cells and focus is moved elsewhere in the app (other focusable controls), the CellValidating event does not fire. Since this is the only means I know of by which to capture the leaving of a cell being edited so I can validate, I'm stuck.

    - Find Target and Change Icons buttons are disabled for desktop Shotcut of my application Dear All, I have made a setup of a C# window application in which i create an icon on the desktop. But the problem with this shortcut is that whenever i right click on it & go to property, its Find Target and Change Icon buttons are disabled. The difference that i have observed between other standard applications shortcuts and this one is that its Target Location on the property page is not set which are set for other ones whereas Target property just points to the name of the application. Please guide me as soon as possible so that i could solve this problem. Regards, Wasif Ehsan. Tag: Windows Forms Designer Implementing SnapLines at RunTime Windows Forms

    - C# How do I keep GroupBoxes seperate? A possible reason why the bottom one may have been controlling the others is that you actually made them contained inside of it. You probably can't drag the group boxes directly to the right location using the mouse. Instead, get it close and then tap the arrow keys to align it exactly (or use some of the alignment tools). That being said, it's still not a very elegant solution. A tab control would probably be my first choice. You can even hide the tabs so it doesn't look like a tab control. See nobugz's post on this thread for an example. Tag: Windows Forms Designer Implementing SnapLines at RunTime Windows Forms

    - Database connection problems Hi all, I have been working on this problem for the full past 2 days, i really need some ones help...PLEASE. I have what at first seems to be a common problem, I have added textboxs etc from the data source. This in turn brought up the table adapter, binding navigator etc. I have the binding controls working except they do not write back to the database. In trying to resolve this issue i downloaded leeson 9 (data binding) from the microsoft web site and found that even this pre written program will not update data back to the database. I am completly baffled by this and really need help on tackling this problem as I am learning this for a university project and the deadline is fast approaching. any help on this issue would be very appriciated.

    - IDE Freezes with high CPU every time form is opened Hi all. I have recently taken over a new C# application as part of my new job and I have encountered a situation that is slowly driving me mad. There is one specific form within the application that takes forever to open in the form designer. I right click View Designer and the form starts to open. Within 5 - 8 seconds the form has completely drawn on screen but then the PC's cpu spikes to near 100% and the IDE just sits there for over 2 1/2 minutes before it suddenly springs back to life. This happens every time I open the form or even when Visual Studio (2005) decides it wants to redraw the form in the designer. With this happening at least 10 times a day I am really getting hit by a productivity loss here. I hope someone can help as I have tried everything I know to figure this out. Here are some details about the form:- It contains about 5 TabControls all with at least three tab pages containing a few TextBoxes and ComboBoxes. There are also around 15 DataGridViews on the form bound to BindingSource controls. The BindingSource controls all have their DataSource properties set to DataTables within a DataSet. There is no code in the constructor (other than InitialiseComponent) or the Load event - in fact I have removed all code behind the form and it still has the problem. I am trying to get them to install SP1 in the hope it might help, but I have a horrible feeling it will make no difference at all. If anyone could suggest how I am supposed to debug this issue I would love to hear it! Any ideas at all would be great. TIA.

Hi Guys

We are in the process of developing a graphics design package using VB.NET 2005. The SnapLines feature in the IDE is excellent and it's the sort of feature we want to implement to align boxes etc automatically.

My question then is does anyone know how to implement the SnapLines functionality at RunTime

Many Thanks

Darm

Re: Windows Forms Designer Implementing SnapLines at RunTime

Martin Thorsen - MSFT

The Snapline functionality is built into the WinForms designer, so unless you want to host the WinForms designer in your application, you have to write your own Snapline implementation.

Sorry,

Martin
