    - ValidateChildren not envoking validation on controls with CausesValidation set to false From my lengthy and painful debugging experiment it seems that UserControl.ValidateChildren() will not envoke validation of child controls where their CausesValidation property is false. I have a rather complex hierarchy starting with a MS CAB SmartPart view placed on an Infragistics UltraTabPageControl tab, which contains a group box, a flow panel and finally some UltraComboEditors. When the ValidateChildren method is run on the view (which inherits from UserControl), it seems to validate only controls which themselves cause validation. I implement Validating() event handlers accross the whole hierarchy, set all CausesValidation to false except the bottom level of combos where I play with various combinations to see the validation being triggered. This dependency seems so odd, because 1 - wasn't ValidateChildren ment exactly a mechanism independent on (alternative to) auto validation controlled by CausesValidation property. 2 - CausesValidation is supposed to control behaviour of other controls, not itself. Am I right about my observation of this schizophrenic character of CausesValidation, is it something particular to the Infragistics controls library, or is something wrong in my test case? Any comments appreciated. Pavel Tag: Associated icon for files in Treeview Tag: 117074

    - DataGridView, DataGridViewComboBoxColumn problems Hi, I've been looking at this for a while now and I have tried 4 or 5 different options and I can't quite get this to work. Requirements I have a DataGridView setup in virtual mode and I want a Combobox column in DropDownCombo style (i.e so you can type a new value in that doesn't exist in the dropdown). If the user types something into the editable portion that doesn't exist in the dropdown I need to perform a search that may find a matching item that I want added to the dropdown, this value should then be selected and pushed back to the datastore. Ideally I'd like to implement an iTunes style fuzzy matching algo as well (perhaps filter the contents of the dropdown but I'd like to get the simple option working first Problem I'm hitting issues with the validation, I've tried several points to hook into the chain of events but none seem early enough to prevent a DataError being thrown because the value I entered isn't in the dropdown Any thoughts on the best way to approach this problem? Thanks in advance for your thoughts David Hayes Tag: Associated icon for files in Treeview Tag: 117073

    - Missing Images while printing in vb.net Hi Toall , I want to explain you clearly , I am having some panels having some controls CheckBox,ComboBox,Datagridview,Hyperlink,label,Listbox,Picturebox,RadioButt= =AD on ,Textbox) &(Oval,Line,Rectangle ). with .BorderStyle =3D BorderStyle.FixedSingle . All these things are generating at runtime using some buttons . I am taking them in to bitmaps and then printing using ACROBAT DISTILLER printer. I am printing each Bitmap on a new page taking e.MarginBounds of PrintPage event using e.Graphics.DrawImage () . I took each control on a single panel. Then i take the panel into bitmap using control.drawtobitmap() .And then I print the things . Suppose if the panel is having Circle or line or ComboBox or Checkbox or DataGridView or URL or ListBox or RadioButton ,it is showing the borders . Suppose if it is having picturebox or rectangle or Textbox missing the borders . or if the panel is not having controls then it is missing the borders while printing . It is showing the borders in printpreview everytime(I have to zoom to look at these things ) but while printing ,sometimes, it is printing with borders ,sometimes it is missing the borders. If it is the last page to print it is missing last 3-4 lines (Missing the image part at bottom ). Suppose, i am having 2 bitmaps having the samesize and controls ,then in 1st page it is printing with controls & borders exactly correct .But while coming to last page, it is missing bottom 3-4 lines which makes the printing incorrect . So any help about this to make the printing correct exactly. Thanks & Regards , Tag: Associated icon for files in Treeview Tag: 117071

    - SendKeys.Send Problem Hello I'm using the SendKeys.Send method for an onscreen keyboard. This works perfect except one problem: If i configure windows to use an english keyboard the call SendKeys.Send("{^}") results in a "^". BUT when my computer is running with an german keyboard, the call SendKeys.Send("{^}") results in a "&". MSDN says: If your application is intended for international use with a variety of keyboards, the use of Send could yield unpredictable results and should be avoided. Okay that sounds bad, the strange thing is that every other keystroke (or text) is working fine, excepts the "^" character. Berni Tag: Associated icon for files in Treeview Tag: 117054

    - c# stop user changing tab on tab control stops events All, I am trying to stop users changing tab pages on a tab control if the tab page has not been validated. This I can do by adding a tab control selected index change event handler and a tab page validating event handler. http://www.syncfusion.com/FAQ/winforms/FAQ_c93c.aspx#q958q However, once validation has failed, no other events are thrown by controls on the same tab page until the tab page has lost and then regained focus. I have attached sample code for a simple form. Uncheck the test box, try to change to tab 2, and then try and click the Tab Button. It does not fire. But it does if you click Form button first. Can anyone suggest a solution to this. I have kept the sample code as simple as possible.

    - Winform to stay on top of a game window I participate in a MMORPG using OpenGL. In conjunction with this, I use a third-party application written in .NET 2.0 that collects data from the MMORPG to help in analyzing my progress etc. I help a bit with the development and maintenance of this window, and have volunteered to TRY to figure out a solution to the following problem. However I am kinda stuck. This 3rd party app includes a form that stays on top of the game to show various in-game data. This works fine under Windows XP, but when using Vista, this "in-game window" does not redraw. Except if the game is running in Windowed mode. When running the game in full-screen under Vista, the in-game window is not drawn. It IS on top, I can move the mouse over the area where the window is, and the cursor will change. If I click it, it will become active and visible. But once the game regains focus, the in- game window is once again "invisible". This must obviously have something to do with the way Vista handles OpenGL, but what can be done to keep the in-game window visible when running the game in full-screen? The form has the TopMost property set to true, and as mentioned it seems to BE on top, just "invisible". Tag: Associated icon for files in Treeview Tag: 117033

    - Hooking into DataSet Auto Generated Code I have an application that I am trying to use auto generated code as much as possible. It makes writing the application so much easier. I have created a DataSet based on an SQL database connection. VS2008 generated the dataset class and code. I need to insert some logic in the UpdateAll method just before the workConnection.Commit() statement. I will be using the allAddedRows and allChangedRows item arrays. I know that if I make changes here they will be erased if the code is re-generated. Is there a method I can override or an event I can subscribe to that will let me do something with the database just after the additions and changes are made? I can start my own transaction if I need to, but I need access to the arrays of added, changed and deleted records. Again, I want to keep things as auto generated as possible.

    - Displaying high-res images in .NET? .NET 1.1/2.0 I have a need to display high-resolution scrollable images in a .NET application (Windows Forms). One well known solution is to create a Panel with AutoScroll set to "true" and then add a PictureBox or another Panel to it, that is used to display the image. The above approach works, however, to my surprise, .NET GDI+-based graphics are not really hi-res friendly. Consider the following codes examples: 1) Bitmap b = new Bitmap( 6000, 6000 ); panel2.BackgroundImage = b; // <-- Works OK 2) Bitmap b = new Bitmap( 14000, 10000 ); panel2.BackgroundImage = b; // <-- "Out of memory" error The full stack of the error is: System.OutOfMemoryException: Out of memory. at System.Drawing.TextureBrush..ctor(Image image, WrapMode wrapMode) at System.Windows.Forms.Control.PaintBackground(PaintEventArgs e, Rectangle rectangle) at System.Windows.Forms.Control.OnPaintBackground(PaintEventArgs pevent) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmEraseBkgnd(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Internally, the TextureBrush constructor makes a call to GdipCreateTexture() method in gdiplus.dll, and, apparently, there is some limit on the image size that the method can handle. Obviously, I am hitting some limit of GDI+ here, but still need to find a solution. I want to stay with .NET, if possible and avoid using any third-party ActiveX controls. What alternatives can I pursue? Will going with .NET 3.x and WPF help? TIA! Tag: Associated icon for files in Treeview Tag: 117007

    - Reading Data From The Browser I'm working on a stand-alone winform app and could add a really cool feature if I could just get the URL of the active tab in the active browser window. Note that the browser would have focus...my app just sits in the background and based on the current URL, it would change the context of information that would be displayed when the user returns focus to me. I haven't touched the IE API's in years, but know there has to be a way. I doubt very seriously that FireFox does, but if anyone has any ideas, it is more than appreciated.

    - Big Problem with Tabcontrol Hi, I have an Windows Forms application written in C# which has a tabcontrol in it. The tabcontrol has many pages in it. Each tabpage deals with a specific feature in the application. e.g. Download, Upload, Erase etc. If I add all the controls directly to the tabpages, then that basically means that I'd have to handle all the logic in the main form itself. However, this would mean that the entire code for the application would be in one class. Hence, I need to split up the tabpages into either separate Windows Forms OR User Controls(based on some info in earlier posts), and then load them at Main Form's Load event into the tabcontrol. I tried loading the forms into the tabpages by doing something like this... form.TopLevel = false; form.FormBorderStyle = FormBorderStyle.None; form.Parent = tab; tab.Controls.Add(form); form.Show(); Now, the problem is that even though the form displays properly in the tab page, some part of the form seems to be missing. The right and bottom parts of the form are not showing, even though the form size and controls are capable of fitting into the tabpage bounds. Also, the controls are much larger than in the form, as if they have been zoomed up. I am having to severely reduce the size of the form to make it display properly, even then the control sizes are not as on the form. The exact same problem occurs even if I use a UserControl instead of a form to host the controls, and do the following... UserControl1 userControl = new UserControl1(); tabPageDownload.Controls.Clear(); tabPageDownload.Controls.Add(userControl); //this line seems to make it fit slightly better into the tabpage, but doesn't solve the problem userControl.Dock = DockStyle.Fill; I have run out of ideas here. Any help would be highly welcome. Windows Forms Gurus, please show me the light! Thanks in advance, Bharat Tag: Associated icon for files in Treeview Tag: 116995

    - SerialPort event not firing after ShowDialog - C# I have a C# application that uses the SerialPort class. The SerialPort is being used for an external input device (a Disto). It works perfectly except when a modal dialog pops up. When a modal window is up the serial port events don't fire. The odd thing is they aren't eaten, they appear to be on hold. When the modal window is closed the events suddenly fire. Since the serial port is being used for an input device I want the events to fire all the time. My understanding is the serial events happen on a secondary thread, and not the main thread. Why are the events being held? Anyone have a clue? Tag: Associated icon for files in Treeview Tag: 116993

    - Printing Multiple Page Documents from Windows App If anyone is willing to look through all this code I've posted below, it would be tremendously appreciated. I can't seem to get the second (or 3rd, etc.) page to print on a new piece of paper. For instance, I have 15 line items in an order. The header and the 1st 12 lines print on page 1, then lines 13 thru 15 print on the same piece of paper directly on top of lines 1 thru 4. I've review the Microsoft examples, but they don't seem to apply exactly to the structure of my document which is composed of a header and detail. Thanks again in advance for any pointers.

    - App design advise Hi I have a third party telephony app that can inform of the any incoming call tel number by one of two methods; a) It can run a windows app with tel number passed as parameter, or b) It can run a vbscript with tel number passed as parameter to the script. My question is how can I design a vb.net app so that it can accept one of the above techniques to pick the incoming tel number when needed.

    - RadioButton DataBinding problem Hi all! I have a custom datasource class with some boolean properties that i want to bind to some RadioButtons in the UI. The RadionButtons are located in the same GroupBox. But the effect is, that the DataBinding will create some feedback that fails the control/datasource communication. When i click a not checked RadioButton, both RadioButtons are not checked afterwards. (I use the .Net Framework 2.0) Any solutions? Thanks in advance Ulrich public class MyDataSource : INotifyPropertyChanged { private bool aChecked; public bool AChecked { get { return aChecked; } set { aChecked = value; this.firePropertyChanged("AChecked"); } } private bool bChecked; public bool BChecked { get { return bChecked; } set { bChecked = value; this.firePropertyChanged("BChecked"); } } private void firePropertyChanged(string propertyName) { if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } public partial class Form1 : Form { private MyDataSource myDataSource; public Form1() { InitializeComponent(); this.myDataSource = new MyDataSource(); this.rbA.DataBindings.Add(new Binding("Checked", myDataSource, "AChecked", false, DataSourceUpdateMode.OnPropertyChanged)); this.rbB.DataBindings.Add(new Binding("Checked", myDataSource, "BChecked", false, DataSourceUpdateMode.OnPropertyChanged)); } } Tag: Associated icon for files in Treeview Tag: 116985

    - C# Application Dies for Only 1 User I have rather odd problem and I am not sure how to go about debugging it. I have an MDI application that I am deploying on the local intranet to about 20 users using ClickOnce deployment. I am just using the default setting in Visual Studio 2005 to deploy the app to an intranet web server. It is a full trust application. After I published the last update one of the users called and said the application would not start for him after the update installed, but was working the day before. No other users are having problems. Basically the problem is: The user starts the application it starts up fine. Then the user clicks on another application that is open causing my app to loose focus. When the user clicks back on my application it shuts down within one second. If the user starts my application and uses Alt+Tab to switch between the applications that are running on the machine the error does not occur. In fact if the user chooses to use Alt+Tab just once to switch between my app and another app the problem goes away even if they start using their mouse to start clicking between my app and another one. Thanks, Erik Tag: Associated icon for files in Treeview Tag: 116980

    - Why can't DataGridView Checkbox cast 0 to Int16? OK, have a simple .Net 2.0 WinForm app, with a DataGridView, which contains a checkbox bound to an Int16 (was a byte). For a certain user (who will be the main user of this app), when clearing the checkbox, and then moving the focus, generates an exception. The exception basically say that 0 is not a valid value for an Int16. The user can tick the checkbox, and not raise an error. It seems that 1 is a valid value. Other users don't have this problem, and it's not linked to the PC being used. Have had 2 users logon onto the same PC, and getting different results. Roaming profiles are in use, so common sense says it's linked to the user's profile. Checked the regional settings, and nothing stands out. Should have said the OS is XP SP2. So, does anyone have an ideas as what I need to check/change in the user's profile? Thanks in advance Tag: Associated icon for files in Treeview Tag: 116966

    - Tab control validation and losing events Hi, Hope someone can help me with this - been going round and round with no progress. I have a form with a tab control containing 2 tabs. Tab 1 has a panel containing a text box and a save & cancel button. We have a validation event on the panel to check the text field is valid and if not we output a message. This all seems to work fine until there is an invalid entry in the textbox, validation message is displayed and e.cancel is set to true. Although the tab doesnt switch pages (correct behaviour) focus seems to be in the ether..... The buttons within the panel will now not fire their click events. Note: If no message is output (or an error provider is used) then the buttons events fire correctly. There is no databinding etc. So issue seems to be output of message in the validating event causes tab control to lose track of focus? - Any one had this before? Help greatly appreciated. Thanks in advance - code below Code: private void pnlOwners_Validating(object sender, CancelEventArgs e) { e.Cancel = false; if (_fieldsChanged) { e.Cancel = true; MessageBox.Show("Correct error before proceeding", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information); } } Tag: Associated icon for files in Treeview Tag: 116963

    - Problems Background Printing PDF from C# Application Hello, We are having a lot of problems trying to print a PDF file in the background using a C# application that is executed via SQL Server Agent. The output should be printed to a local printer (HP Color LaserJet 1600) connected via a USB port. We have a C# application that calls System.Diagnostics.Process to run Acrobat Reader (weâ??ve tried both v8.0.0 and v8.1.2), open an existing PDF file, and send it to the local printer. The code is shown below. System.Diagnostics.Process process = new System.Diagnostics.Process(); process.Refresh(); process.StartInfo.Arguments = "/t C:\Temp\TestPDF.pdf"; // and tried "/t C:\Temp\TestPDF.pdf PrinterName" process.StartInfo.CreateNoWindow = false; //process.StartInfo.Domain; //process.StartInfo.ErrorDialog = false; process.StartInfo.FileName = "C:\\Program Files\\Adobe\\Reader 8.0\\Reader\\AcroRd32.exe"; //process.StartInfo.Password; //process.StartInfo.UserName; process.StartInfo.UseShellExecute = false; //process.StartInfo.Verb = "Print"; process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; process.StartInfo.WorkingDirectory = new System.IO.FileInfo(m_PDFPathFile).DirectoryName; process.Start(); Weâ??ve tried just about every combination of the process objects properties trying to get the PDF file to print. But, it never works. The code executes without error, just nothing ever shows up on the printer. More infoâ?¦ Weâ??re executing our custom C# application via a SQL Server Agent job. SQL Server Agent is running as Local System account. The Job Step Type is Operating System (CmdExec), with Run as set to SQL Server Agent Account. The command is simply the path and file name of our custom C# application (e.g., C:\Temp\PrintPDF.exe). Again, we get no errors/exception and no job failures, but the PDF never gets printed. How can we re-code or fix our situation? What can be done/tried? All help is appreciated. We are stuck. Thanks. Tag: Associated icon for files in Treeview Tag: 116960

    - WebBrowser control I'm trying to do my own scrolling with the WebBrowser control. I can use the WebBrowser.Document.Window.ScrollTo method to scroll to a specific position but how do I get my current scroll position? I know when the document loads that I'm at scroll position 0,0. Then each time I scroll (by 200 for example) I just keep a record of my new scroll position. This works until I get to the end of the document. The ScrollTo doesn't return any feedback when it gets to the end of the document, so I don't know when stop scrolling and when to stop adding 200 to my internal scroll position. Is there a way to read the current scroll position? Tag: Associated icon for files in Treeview Tag: 116959

    - Windows DPI scaling Hi, C# .NET 2.0 I'm developing a windows application that will run on a number of machines typically with DPI of either 96 or 120. By setting the AutoScaleMode on different forms to DPI I get the required scaling results. However, I have one form that contains a richtextbox that's anchored to top, left and bottom borders and where I change the width of the richtextbox depending on values taken from a PageSetupDialog control. Something like this: this.pageWidth = this.pageSetupDialog1.PageSettings.Bounds.Width - this.pageSetupDialog1.PageSettings.Margins.Left - this.pageSetupDialog1.PageSettings.Margins.Right; this.txtWritingPad.Width = pageWidth; The problem now is that a single line of text that fits on one single line in 96 dpi gets wrapped to the second line in 120 dpi. Font and font size are the same. I need the text/font to appear the same on both machines. i.e. on one line from left to right. I thought that maybe because I was explicitly setting the width of the control at run time I would have to call PerformAutoScale() but that doesn't seem to have any effect. I'm obviously missing something. Can anybody help? Thanks, Damien Tag: Associated icon for files in Treeview Tag: 116956

    - 'ShowInTaskBar crashes .NET in Form Activated and Deactivate events Copyright assigned 2008 to "microsoft.public.dotnet.framework.windowsforms" Usenet Forum (see note at end for clarification) I am quite clear right now that this problem ONLY arises when you try to change a Form's ShowInTaskBar property in its Form_Activated and Form_Deactivate events. I believe there is a high probability that this is related to the fact that ShowInTaskBar under the hood is invoking the window styles api ... most likely the window is being re-created ... and this is triggering recursive firing of events somehow interacting with whatever the Activated and Deactivate events are doing. It is surprising that I have not been able to find a definitive statement from MS on this on MSDN, but right now (since I switched to Internet Explorer 8 beta 1) MSDN pages take literally minutes to refresh in my browser. This is in part due to a significant apparent breakdown in my ISP's (northern Thailand) ADSL service which has lasted ten days now. So those factors have limited my time for searching MSDN. I am creating a work around for this now in my own application using a "dummy window" as a minimization placeholder for the case when the end-user selects the option to show only the current active window in the taskbar (rather than just allowing all active open windows of #n windows to show in the taskbar). I tried several "work-arounds" for this that involved things like raising an event up to a static event-handler in a Class from the Activated and Deactivate events : whatever I tried ... if it was triggered by these two events, it crashed .NET. It's a kludge, it's ugly, but it will work. I have no idea if you could work around this using API's or not, but the application I am writing must not use WndProc's and such. best, Bill copyright notice : for use by any non-commercial, non-profit, advertising free Usenet or Internet forum : you may not republish this message on any website with commercial advertisements.

'Icon.ExtractAssociatedIcon'. You may also take a look at the documentation
on the Win32 listview control (the control the .NET listview control is
based on) for system image list support.
