    - Error When Trying to copy a row from a datagrid Hi, I have a vb.net windows form with a datagrid, and I am simply trying to click on a row, hit CTRL-C to copy and then CTRL-P to paste it somewhere else. This works fine for individual cells. When I try it with an entire row however, I get the following error: DataGridColumnStyle of '' cannot be used because it is not associated with a Property or Column in the DataSource. This error occurs as soon as I hit CTRL-C. Strangely the unhandled exception occurs at the definition of the parent form ("Public Class Mainform"), even though the datagrid is located on a child form. Does anyone know what is going on. I want to be able to copy and paste whole rows, but even if I can't, I really can't have the users getting unhandled errors for trying. Anyone seen this before?

    - Webbrowser Control and multiply document complete (Frame sites) We have the following problem. We are using the system.windows.forms.webbrowser control to navigate and interact with some webpages. When the document contains frames we are getting multiply documentcomplete events. Is there any way to know when the FULLDOCUMENT (all the frames) complete? Also the event on the same page fires different times on each test (maybee the caching?) -- Mike Evans Tag: Loop through Controls using a class Tag: 109557

    - Propertygrid issue Hi, I have an application which has two winforms. One is the parent form which has around 20 odd controls. And the other has a propertygrid and two buttons, viz OK and Cancel. This form runs in the designerhost. Hence if a property is changed the componentchanged event fires and changes are seen on the control on my first form. Is there a way to defer this event such that on click of OK button the changes are reflected and on click of cancel i get an option to rollback or revert the changes. Thanks for all the help.

    - Opening MDI Child From MDI Child Form, like VisStudio Start Page Hi, I have an MDI application which contains a start page with a listview of items in it that can be used to click on and open as a child form. So the start page is the child at start up of form. However, when I try to open another child from this start form it opens ok, but will not show or focus on the new form, it keeps coming back to itself? Why would this be? I open the form like so from the start page. MPE.PolForm polWin = new MPE.PolForm(); polWin.Show(); and then in the polForm I do this.MdiParent = mainForm; and mainForm.windowManagerPanel1.AddWindow(this) Any ideas? The windowManagerPanel1 is a tabbed form control that behaves like visual studio 2005. Why does it always go back to the start form and not show the new created form.

    - Problem with label word wrap and accented characters Hi, It seems that the .NET Label control incorrectly wraps words at accented characters (or non-ascii characters in general). The same is observed when using Graphics.DrawString() directly. I am using .NET Framework 1.1. The text "Vous obtiendrez une meilleure traduction en Ã©vitant les abrÃ©viations et les tournures familiÃ¨res." is wrapped by the label as follows: Vous obtiendrez une meilleure traduction en Ã©[\n] vitant les abrÃ©viations et les tournures familiÃ¨[\n] res If I simply remove the diacritics, it wraps correctly: Vous obtiendrez une meilleure traduction en[\n] evitant les abreviations et les tournures[\n] familieres I also observe incorrect word wrapping when using the Greek alphabet. Where can I find information about this problem? Is there a solution? Thank you, Bret Tag: Loop through Controls using a class Tag: 109550

    - AutoResizeColumns in a DataGridView Hi All VS 2005 SP1 I use a DataGridView to display some figures. I have a cellpainting event that displays a couple of numbers in bold and other numbers in regular font style. When i double click the Column devider it resizes the column so that the regular formated columns fit in but not the bold formated columns. What is te best workaround for this problem? I tryed overwritting the ColumnDividerDoubleClick event: private void gridEditColumn_ColumnDividerDoubleClick(object sender, DataGridViewColumnDividerDoubleClickEventArgs e) { Font font = new Font(gridEditColumn.DefaultCellStyle.Font, FontStyle.Bold); Graphics g = gridEditColumn.CreateGraphics(); Size s; int width = 0; for (int i = 0; i < gridEditColumn.Rows.Count; i++) { s = g.MeasureString(gridEditColumn.Rows[i].Cells[e.ColumnIndex].FormattedValue.ToString(), font).ToSize(); if (width < s.Width) { width = s.Width; } } gridEditColumn.Columns[e.ColumnIndex].Width = width; e.Handled = true; } but the width i get is still to small so that the bold value doesn't fit in... i'm scared to just add a couple of pixels to the width...or do i have to do so? is there a better way to do it? thanks for your help. jahrens Tag: Loop through Controls using a class Tag: 109549

    - Europe Tests Established Chemicals on Millions of Animals Tony Nottingham England 28 February 2007 TO: All People Who Care A new European Chemical Testing Policy called REACH has now been finalised by the European Union. Under these proposals Chemicals of every kind - from those used in industrial processes to the ingredients of consumer products - will be tested on Millions of animals from mice to fish to dogs, causing untold suffering. Still worse, because of this reliance on outdated animal techniques, reliable and relevant information will not be provided and our safety will not be assured. If you believe that REACH should make more use of Alternative Testing to test 1000s of Chemicals that have been in general use since before 1985 then please take action now. If you are a European citizen please contact your local papers and own MEP asking them to promote the development of humane non-animal testing methods under the REACH legislation, which is the best hope we have for sparing animals the misery of a testing laboratory. A sample letter can be found at the BUAV (British Union for the Abolition of Vivisection) website at www.BUAV.org (Select Campaigns, Chemical Testing, Get Active then Writing to the local press). For all Non-European members, you can still help. Please tell all your colleagues and friends in the UK and Europe about REACH. Write to your own local papers to try and inform others about what is going on in Europe. The website for the European Parliament is http://www.europarl.europa.eu. Information on REACH, the New European Chemical Testing Policy can be found here. Everyone can help and you can make a difference. Thank You Tag: Loop through Controls using a class Tag: 109546

    - datetime picker problems Hello we have encountered the following problems with the date time picker control A : datetime picker control gives focus to last entered field when moving back and forward with focus how do we reset this to the first field ? B : datetime picker in DD-MM-YYYY default format ( europe , NL-NL localization ) refuses an entry of 31 on the DD filed cause the month is already chosen to the current mont ( (02) februari wich only has 28 days ) steps to reproduce these problems A : can be reproduced on any system Throw a datetime picker control , and a textbox on a form ,set the Datetime picker format to short , start the project , now enter a date , move the focus to the textbox with the tab key , move the focus back with the tabkey , you will notice that the when the focus is given back to the datetime picker control it will select ( highlight ) the last entry box instead of the first that we expected B : can only be reproduced on a system with DD-MM-YYYY settings , when the form is started the Datetime picker will start with the current month ( 2 ) however if i want to enter 31-12-2006 i need to change the month part first Why is the above a problem ? Well we are currently building a production system , and for data entry this behavior is verry unwanted as it will take extra steps for the operator to enter valid data in the system . For B : i have coded a solution however not completely to my satisfaction i just default the control to 31-12-YYYY ( where YYYY = the current year ) however A: is a serious problem that i can`t solve yet regards Michel Tag: Loop through Controls using a class Tag: 109535

    - Remove last row in a unbound datagridview Hi All, I have a undound DataGridView. That is, I am populating the DataGridView using the DataGridView.Rows.Add() call and by setting the values to individual cells in the row. When I am adding data to the DataGridView using such a method, I am getting an unwanted row at the bottom of the DataGridView. I want to avoid this row. Any help with respect to this is highly appreciated. I am not planning to use databinding for the DataGridView. Since, the DataGridView has 7 columns. I should be able to sort the DataGridView using any of these seven columns. If I use the databinding, it will be difficult to sort the view. Hence, using the Default sort of the DataGridView helps me in this case. But the presence of last row in the DataGridView should not be supported. So, please tell me a good method, using which I can remove the unwanted last row in the DataGridView. Thanx In Advance, Sudeesh G Tag: Loop through Controls using a class Tag: 109527

    - How to improve performance for stock exchange data display received from third party com component Hi, I could not get the answer on the Performance community hence forwarding the same issue here... I am using a third party COM component to get very very fast data stream. I have dragged the com component on a windows form. Now we can request the data for specific symbols on this com component and in turn it will start pouring in data in form of continuous events for the requested symbols. The problem is that data stream is too fast and can easily make the CPU go to 100%. The tricks which I am thinking to tackle the issue are ... 1) Instantiate the com component form on the new thread and put the data in alternate generic dictionaries (We have 2 side by side dictionaries. One dictionary start filling with data then other dictionary is being accessed by the consumer module) . So a dedicated thread of consumer class with poll in the alternated dictionary after a certain time interval, set the flag on 1 dictionary and start copying the data from alternated dictionary to another datastructure BindableDictionary(It is a wrapper arround 2 data structures - 1 BindingList<> and 1 Dictionary<>. As the name suggest, as soon as the consumer module copies data in BindableDictionary, it start displaying it on UI.) [STAThread] private void InstantiateCOMComponent(object state) { _comManager = comComponentForm.GetInstance(); Application.Run(new comComponentForm()); _comManager.Visible = false; } but as soon as we try to instantiate the COM component on the new thread, it gives the error - Message "ActiveX control '7b0deade-e17b-11d2-93e6-00a0c91827c9' cannot be instantiated because the current thread is not in a single-threaded apartment." 2) Because of the com component error, Another alternative could be to apply the com component on a windows form in a new exe and make it a server. Then supply data through sockets to clients. Please suggest/comment about the alternatives given above or any better way of solving the business problem. I appreciate you reading a long email.

    - Binging custom objects to the DataGridViewComboBoxColumn Hi, I have bound a collection of type IBindingList to a DataGridView. Each object in the collection contains various string properties, Customer Name, Contact Name etc. It also contains a property 'MyOrder' of custom type 'Order'. The Order class simply contains properties like OrderID, OrderName etc. I add the columns to the Grid of type DataGridViewTextBoxColumn for the strings and DataGridViewComboBoxColumn for the 'Order' object, the code for the combo column is as follows: DataGridViewComboBoxColumn cboCustmomerOrder = new DataGridViewComboBoxColumn(); cboCustmomerOrder.HeaderText = "Order"; cboCustmomerOrder.DataPropertyName = "MyOrder"; cboCustmomerOrder.Name = "OrderName"; //cboCustmomerOrder.ValueType = Order; cboCustmomerOrder.DataSource = m_Cust.OrderCol; this.dataGridView1.Columns.Add(cboCustmomerOrder); The datasource is set to a collection of type Order (List<Order>) Everything displays OK and I can make selections from the dropdowns. When I try to tab away however, I get the following error: [System.FormatException] = {"Invalid cast from 'System.String' to 'BusinessComponentExample.Order'."} I have spent ages trying to find out how to handle this but so far only found that the error can be trapped as follows: private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e) { if (e.Exception != null && e.Context == DataGridViewDataErrorContexts.Commit) { //Do something } } Obviously I need to cast to type 'Order', but my question is how? Hope this all makes sense, please let me know if not. Would be delighted to get an answer or a pointer to a good tutorial. Couldn't find any that explain how to do this.

    - IDE BindingSource error message I used the Data Sources window to drop a custom object onto the designer surface. It created a BindingSource and BindingNavigator as a result. When I open the Properties window on the BindingSource, I see DataSource property set to the object I created. However, when I try to dropdown the DataSource property, I get the message: "Object reference not set to an instance of an object". The title of the messagebox is "Microsoft Visual Studio". So I cannot change the DataSource! I went into the designer file and removed the DataSource property of the BindingSource and went back into the designer. It showed the DataSource as (none) as I expected. But the same error message occurs when I try to change the property with the dropdown box. What is going on?

    - Tooltip on Combobox disappears - Windows Forms bug? I am using .NET 2.0 forms and running on Windows XP SP2. When I have a tooltip on a combo box, and the combo box is expanded (?dropped down?) using the arrow, then collapsed, it will no longer display it?s tooltip, no matter how long I hover.

Below is a small sample that has this bug (on my machine anyway.) It is simply the standard VS8.0 generated code, condensed.

    - Displaying a selected ListViewItem Hi~ I'm writing an application that displays a list of files in a ListView control and updates their status while filtering and copying processes happen, i.e. - I copy a file, that file's status is displayed as being transfered. I filter a file, it then shows the result of the filtering, etc. The thing is this - If I use labels to display the "currently worked-on" item, the program can't keep up the pace for small files since they get copied and scanned so fast, so the messages coming in from the BackgrounWorkers just plug up the system. Is there a way to set the ListView to show the currently selected ListViewItem, so I can just focus on it as I go along with the copying and filtering?

    - .Net 2.0 Pb with multi threads and DataSet dataBinding Hi, I've build an application that use several threads in background. These threads are managed by a manager object and store control data in a dataset. I've also bound the DataSet to a GridView control. When I run the application, althought I "see" the gridview control to be filled and updated byt the actual values filles from the background threads, the application is blocked. So my question is : Is the dataset thread safe ? If not, and in a more general manner, are databounded controls thread safe ?

    - Asynchronous Programming Model - how to implement? Hi, I'm trying to implement APM (Asynchronous Programming Model) API by myself - I mean: IAsyncResult BeginMyFunc(AsyncCallback, object @object); void EndMyFunc(IAsyncResult result); functions pair. The problem is that my working thread has to report updates to the GUI by System.Windows.Forms.Control.Invoke(Delegate method) invocation. How to implement my EndMyFunc(IAsyncResult result) function? It should be something like this inside: result.AsyncWaitHandle.WaitOne(); where AsyncWaitHandle is ManualResetEvent or something like this. Unfortunately, this approach will prevent my GUI thread from handling SendMessage calls coming from working thread invocations of System.Windows.Forms.Control.Invoke(Delegate method). Deadlock is about to happen. The same problem is about terminating phase. I cannot just call this by GUI thread: workingThread.Join(); because of System.Windows.Forms.Control.Invoke(Delegate method) invocations coming from the working thread. The deadlock again. What I need is some kind of .NET replacement for MsgWaitForMultipleObjects + some necessary message pumping. How to properly implement it in .NET 2.0? many thanks in advance, -- dmitry Tag: Loop through Controls using a class Tag: 109445

    - Topmost form loses the topmost status when VS2005 is run Hi, I've created a sample project in C# (both in VS 2003 and 2005) that uses just one form and sets its topmost property to true. I run the application and I noticed that everytime I run VS 2005 it loses the topmost status (it is hidden by the VS 2005 IDE). I noticed that the value of the topmost properties continues to be true, even if the form is no longer visible on the screen (covered by the VS2005 window) The only way to make it topmost is clicking on it. I noticed that this behaviour happens also in other occasions (but I couldn't figure out to which they were related). I need the form to be topmost all the time. Do you have any suggestion on how to fix that, maybe using the Windows API directly? Thank you. Andrea Tag: Loop through Controls using a class Tag: 109440

    - Strange concurrency error Hi I have a perfectly working vs 2003 winform data app. All the data access code has been generated using the data adapter wizard and then pasted into the app. I had to add a new field in the backend access db which I did. I then dragged the table to the dataset and deleted the old table from the dataset it so the dataset can see the new field as well. The problem is that when in update command code I add these two lines Me.updcomCompanies.Parameters.Add(New System.Data.OleDb.OleDbParameter("Web_Enabled", System.Data.OleDb.OleDbType.Boolean, 2, "Web_Enabled")) and Me.updcomCompanies.Parameters.Add(New System.Data.OleDb.OleDbParameter("Original_Web_Enabled", System.Data.OleDb.OleDbType.Boolean, 2, System.Data.ParameterDirection.Input, False, CType(0, Byte), CType(0, Byte), "Web_Enabled", System.Data.DataRowVersion.Original, Nothing)) I startgetting a data concurrency error on mydataadapter.update() method. I know that there is no data concurrency problem as I am the only user testing the app. Obviously the error is misleading. What can I do from here to fix this problem?

    - WPF v Windows Forms Hello all, I am just trying to get up to speed with WPF (and .Net 3.0 in general), and trying to decide whether it is worth using WPF for a new business application (job tracking) which will be used by small businesses on windows Pcs (XP/Vista). Hope to have it ready by late 2007. The only reasons I can see to use WPF instead of WinForms are: Built on direct X and not win32 subsystem for graphics rendering (but what precisely is the benefit of that for a business app?) XAML may be easier for designers (non coders); Possibly can acheive a new look which Winforms cannot (but not sure what that is - any examples?) What other specific reasons should be taken into account? Thanks Tag: Loop through Controls using a class Tag: 109433

    - Combo box in DataGrid Hello - when I create a datagrid and select the combobox as the column type, the application won't allow me to type freeform text into the combobox when the application is run. It will only allow me to select items from the drop down list. As far as I can tell, a normal combobox will let you select items from a list OR allow freeform text to be entered. Not so on the datagrid. Is this feature not available within a datagrid? btw - Using VB.net 2005 Thanks in advance... Tag: Loop through Controls using a class Tag: 109430

    - View - Controller Question for Windows Forms I have an app that has a MainWindow with a menu and toolbar. On the form, I have a SplitContainer with 2 vertical panels. The left hand side panel has an Outlook navigator bar and the right hand side will hold user control forms, which will change depending on which form the user wants to see, ex. customer, invoice, inventory. I have a controller class for each of the different forms, CustomerController, InventoryController etc. All events will be passed to the controller class by the view. Now the question that I have is which view should receive the events from the menu, toolbar and navigator bar. The MainWindow which is holding them, the panel that the navigator bar is in or the user control which represents the form. Regardless of who gets the messgage, it will get passed to the appropriate controller class. I don't want to use CAB here but I believe that CAB is overkill for my app. Bill Tag: Loop through Controls using a class Tag: 109428

Hello,

I just started using WinForms and built the following to hide panels:

private void AppCodeHidePanels()
{
foreach(Control ctrl in this.Controls)
{
if(ctrl is Panel) ((Panel)(ctrl)).Visible = false;
}
}

I would like to move this to a class so that All my forms can use the same
code. My question is how do I reference the form that is calling it. I am
assuming that you can't use "this.Controls".

Thanks,

sck10

Pass it in as a parameter.
