    - Drawing a rectangle around to points (a line). OK...This should be elementary but a lack of sleep is apparently blocking my thought processes... I've two points (p1, p2) and I've drawn a line between them: grahix.DrawLine(new Pen(Color.Red,4F),From.Point,To.Point); How can I now draw a rectangle around the line that exactly fits the length, width, and thickness of the line based on the two points. I can't seem to get it right... Thanks!!! Tag: DataGridView add new row WITHOUT typing Tag: 97210

    - ResizeBegin & Change Size Programmatically Here is what I would like to do. The app's main form is a MdiContainer containing forms. When the user changes the size of the container the child forms are resized, too. I need to catch the beginning and end of the resizing of the child form. How can this be done. This is what is done currently. The container overrides OnResize. In this function the children's position and size is continuously adjusted as the user keeps on resizing the container. In the child forms I have overriden ResizeBegin and ResizeEnd. Unfortunately, they are not being called as they only react to manual resizing and not to programmatically changed sizes (like SizeChanged vs Resize). Are there any events like ResizeBegin and ResizeEnd that also respond when the resizing is done programmatically? If not what is the best solution to achieve this besides the main form telling the children that resizing begins/ends? Thanks Tag: DataGridView add new row WITHOUT typing Tag: 97209

    - StatusBar sizing grip does not work correctly on dual screen displ I created a simple Windows form application with the status bar. Because I use a dual screen display I noticed that there is a problem with the sizing grip when I drag the form to the second screen. The sizing grip does not work when the form is shown on the second screen. I looked at other applications to see if this is a generic problem, but the sizing grip in other applications (like Internet Explorer) behaves correctly. Is this a bug in .NET Framework?

    - Deployment Project - Custom Checkbox Form - Can't reference value! I created a setup project in VS.NET 2k5 and added an additional dialog to ask the user where they would like to place icons for my application. The options are Desktop and QuickLaunch Menu. When the user unchecks one of these, or checks one of these, the value is completely disregarded by my setup project when installation commences. I have found other users complaining of the same thing, and I have followed the instructions given at: http://msdn2.microsoft.com/en-us/library/k3bb4tfd.aspx under the "To add the samples to the installer" section about 3/4 of the way down the page. Other users having this same issue can be found at http://discuss.develop.com/archives/wa.exe?A2=ind0511a&L=dotnet-winforms&T=0&F=&S=&P=651 Thank you for any advice!

    - control change events altering other controls. I have occasions when a user changes the entry in one control the entry in another control is automatically changed. I have got into a muddle and I am not sure if I should be changing the value of the second control, or the field in the underlying record that the control is bound to. I want to do this in such a way that the CancelEdit feature works. As a specific example I am using the CheckedChanged event of a check box to clear the data in another field if the check box is cleared. many thanks in advance Rod Tag: DataGridView add new row WITHOUT typing Tag: 97195

    - ClickOnce, MSBuild and multiple servers. We're currently getting ready to deploy an application using ClickOnce. We'll be placing the deployment on two servers. Because the app.config files will need to point to different servers, we're using the revision number to indicate which server it came from. Currently, this means manually changing the version in the IDE and then publishing to each server. Is there any way to automate this using MSBuild? After looking around it appears MSbuild might be able to generate the files for publishing, but they would then need to be copied to the publish site, is this correct? Can you specify the version number in the build? -- Neil Tag: DataGridView add new row WITHOUT typing Tag: 97193

    - Is Wizard control only available for ASP.NET? It would be nice to have Wizard control in WinForms. Yes, there is User Interface Process Application Block available, but if I need a simple two-step wizard, it is an overkill. It won't take very long to make a simple wizard from scratch, but it is still nice to have a simple light-weight control that can be reused... Why isn't it a part of WinForms?

    - backgroundworker Question We have been using multi-threading in our application in 2003 with good results. When we migrated to 2005 our old code blew up, so we rewrote our code using the backgroundworker. It seemed to easy to be true. When we run our application now it seems that the screens are running synchronously and not Async. We usually have 3 to 4 backgroundworkers going at the same time inside the activated event for the form. See the code below to show how we are using the worker: Private QueueWorker As New BackgroundWorker Delegate Sub QueueDelegate() Private Sub LoadInitialQueue(ByVal sender As Object, ByVal e As DoWorkEventArgs) Try Dim ReturnAsync As IAsyncResult = BeginInvoke(New QueueDelegate(AddressOf SetupQueue)) EndInvoke(ReturnAsync) Catch exp As Exception MessageBox.Show(exp.Message.ToString) End Try End Sub Public Sub SetupQueue() Try QueueFlex.Redraw = False dsNotifications.Clear() dsNotifications.Reset() Dim parm() As Object = {Main.oProperties.UsersBankLoanTeamID, 0} DBCalls.AccessDataLayer.FillDataset("SelUserNotifications", Main.oProperties.ConnectionString, dsNotifications, New String() {"queue"}, parm) QueueFlex.DataSource = dsNotifications.Tables("queue") FormatQueue() QueueFlex.Redraw = True Catch exp As Exception MessageBox.Show(exp.Message.ToString) End Try End Sub Do we have to use BeginInvoke & EndInvoke with this new component because that seems like the bottleneck. If we do still need to use them what can I do differently that would make the UI more responsive. It just seems that we lost the UI responsiveness when we moved over to the backgroundworker. it looks like it gets the data from the sql server async but it doesn't populate the controls async so it looks sync. I don't know any help would be appreciated. Tag: DataGridView add new row WITHOUT typing Tag: 97191

    - Click Event on MenuItem with subitems Hi group, I have a MenuItem with some subitems. I don't want the Click-Event of the MenuItem to show me the subitems, but to do something else - e.g. opening a dialog. The subitems will be shown anyway by mouseOver. MenuItem submenuImages = new MenuItem("Image", new EventHandler(this.menuItem_Image)); or submenuImages.Click += new EventHandler(menuItem_Image); But this EventHandler is never accessed. Why? I also tried to derive from MenuItem to create my own MenuItem and overwrite it's OnClick - but it seems to me, that this is not possible.

    - Form Loading Issue - VS.NET 2003 Hello, I have a dialog in my VB.NET application that has some controls for configuration and an "Apply" button. The design calls for the Apply button to be enabled only after the user has made changes to the settings. To do this the change events for each control are used and the Apply button enabled when any control raises a change event. The problem is that when the form loads and default values are output the controls (correctly) fire change events. Is there a mechanism to get around this, so that only user changes enable the Apply button? Thanks, Sid. Tag: DataGridView add new row WITHOUT typing Tag: 97163

    - ComboBox design-time DataBinding setting questions. These setting mystify me for these reasons. *SelectedItem* - Help says that 'SelectedItem' gets or sets the currently selected item in the combobox. *SelectedValue* - Help says that 'SelectedValue' gets or sets the value of the member property specified by the ValueMember property. *ValueMember* - Help says that the 'ValueMember' Gets or sets the property to use as the actual value for the items in the ListControl. The above three properties are described as results of runtime events! What are they doing in the properties section of the ComboBox????? How do I use them to sync a databound combobox on a form with the current bound row on the form? Please help me understand how to use these settings?

    - maximized MDI Child position shifts Hi. I'm using VS2005, Framwork 2.0. I have an MDI app. The child forms are maximized within the parent. The child forms have the controlbox property set to false and the text property is empty. When my child form opens, the top 40 pixels or so get covered up by the parent. It seems that the child form is shifted up. So I changed my child form so that all controls are shifted 40 pixels down, leaving 40 pixels of empty space at the top. When I do this, the child form shows up correctly as the empty space gets covered up rather than my controls. But once and a while (I haven't found the pattern yet) the child form will shift back down that 40 pixels leaving me with blank space up top and covered controls down below. Has anyone else seen this behavior? I have noticed that if I put a value in for the text property of the child form, I don't have to shift my controls down 40 pixels and I don't get the random shifting. But the parent form takes this child text property and appends it to it's own text property in brackets. Mabye the answer is to put something in the child text property and somehow override how the parent writes it's text property? Can someone help me on how to do this? Thanks in advance.

    - Dll Reference Performance Are there any performance issues, if we have many dll reference added to our project. Any way, does it take more time to load the application if we have many dll reference added to a project, even though we don't use at application load. Does more dll takes more time to load. If we merge many dll into one does it improve the performance. Our application takes long time to load, and we are doing nothing at startup. We are using "no touch deployment".

    - Making a Winforms app behave like a Console app I am attempting to add a "console mode" to my Winforms app. My intention is that when I start the app with a special switch (for example "myapp.exe /batch") to does not launch a graphical UI but instead just displays console messages. My first guess was to simply change the Main method of the startup class to do something like this... if (batchMode) { Console.WriteLine("Now in batch mode"); ... } else { MainForm.Run(); // Launch graphical user interface } Unfortunately, it looks like my app does not behave like a real console mode app in either case. When I execute the app from the command line, the app returns immediately and text output by Console.Write() does not appear anywhere. Setting the app as a Console mode application does not give me what I want either. With this mode, a big black console output box appears even when in "GUI mode". Is there a way to build one executable that supports both modes and dynamically switches at runtime? Tag: DataGridView add new row WITHOUT typing Tag: 97151

    - Sync databound combobox to current bound record in form VS2005 I've been reading all the help I can on the topic (MSDN, other) but I can't make sense of this. Desired behavior; The user is to choose from the displayed list of the databound combobox and the coresponding 'Id' from the lookup table is to be inserted into the field of the new record. I have two simple tables. "tblPerson" is the data table. The lookup table is "lkpPersonType". The combobox dropdownstyle is "dropdownlist" to limit the user to the list. Here are the two tables "tblPerson" Id int IDENTITY (1, 1) NOT NULL , Name varchar(50), Address varchar(50), fkPersonTypeId smallint "lkpPersonType" pkPersonTypeId smallint IDENTITY (1, 1) NOT NULL , Type varchar(50) NOT NULL , The form has two binding sources "TblPersonBindingSource" for the data table and "lkpPersonTypeBindingSource" for the lookup table. The Display Member of the combobox is the "Type" field and the value member is "pkPersonTypeId" field. The Text property of the combobox is set to the "fkPersonTypeId" of the table "tblPerson". The next parts I am unsure of... I did not set the Selected Value (???) I set the Selected Item to the "Type" field of the lookup table lkpPersonType When I run the app the combobox populates. The data seems to display properly for the first record, but the combobox does not cycle through the values I know are assigned to it for the other records. In other words it is not properly bound. However there is a relationship between the two tables in the dataset, but the relationship is not specifically refered to in the form. Here is my code in the load event; \\ Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TblPersonTableAdapter.Fill(Me.DataSet1.tblPerson) Me.LkpPersonTypeTableAdapter.Fill(Me.DataSet1.lkpPersonType) Me.FkPersonTypeIdComboBox.DataSource = Me.lkpPersonTypeBindingSource Me.FkPersonTypeIdComboBox.DisplayMember = "Type" Me.FkPersonTypeIdComboBox.ValueMember = "pkPersonTypeId" 'Me.FkPersonTypeIdComboBox.SelectedValue = ??? 'Me.FkPersonTypeIdComboBox.SelectedItem = "Type" Me.FkPersonTypeIdComboBox.Text = "TblPersonBindingSource.fkPersonTypeId" End Sub // Please help me make some sense of this and get it working.

    - How can I find BindingSource has some changed data. Hi, In my WinForms application, I have a set of controls that are bound to a BindingSource control. When the user closes the form, I need to ask him if he wants to save data. The problem is I cannot find anyway to check if the value of any textboxes is changed! Obviously checking DataSet.HasChange is not adequate. The reason is that the user might be in middle of adding or editing a record so the record has not been reflected to underlying dataset yet, but user accidentally clicks on form close button.

    - Does anyone have an example of the UndoEngine workign with a custom IComponentChangeService implementation? Just trying to figure out how to get a service working that has no viable public methods... My current problem is that nothign ever gets added to the undo stack... All of the other methods are getting called. So my base assumption right now that is that my custom implementation is either preventing the UndoEngine service from getting called or that the designer example from MS that doesn't use a designer class, is unaware of the UndoEngine. ANyway, my head for the designer class is this: public class RootDesigner : IContainer, IDesignerHost, IDesignerLoaderHost, IComponentChangeService, IExtenderProviderService, IToolboxUser, IDesignerEventService { Changing my OnChanged event to trigger the UndoEngine is possible, I'll have to make some public accessor methods on the UndoEngien implementation. However, currently my changed event get's called more than once for 1 user operation. In the case of coping, 1 for the copy and 3 or 4 more for changing properties... This of course would not be a very optimal implementation of undo to have 4 entries for 1 user change. :( Anyways, any help appreciated. Tag: DataGridView add new row WITHOUT typing Tag: 97122

    - Autocomplete textbox Hello all! I'm looking for ideas on implementing a textbox with autocomplete functionality, just like the one found in Excel. As the user types values into the textbox a lookup for matching values is performed. For example lets assume that the user types the character '1' and that the candidate values are '01', '02', '03', '10', '12' etc. I need the textbox to display the first candidate value that partially matches the characters typed ('01'). The cursor should be located at the end of the user typed value (1|0) and the rest of the text must be selected. As the user goes on typing, the selected text is replaced with the typed character and the lookup is performed again. I am very close. I use the Textbox.SelectionStart and Textbox.SelectionLength properties but the problem is that the caret is allways placed at the end of the selection when I need it to be located at the begining. Any Ideas? Thanks! PS: I cannot use a combobox! Tag: DataGridView add new row WITHOUT typing Tag: 97098

    - DataGridView's selected row after a sort How would I persist a DataGridView's selected row after a sort? Tag: DataGridView add new row WITHOUT typing Tag: 97087

Hi,

I've a databound DataGridView that contains 4 textbox column. Each textbox
column has also has a button column that pops up a window to search.

When the user types some text in one of the textbox columns, a new row is
added automatically on the first keystroke. This DOESN'T happen when the
users clicks on a button, and I fill in the value of the textbox column in
code. If the users uses the buttons to fill all 4 textbox columns, there
isn't a new row to continue...

How can I add a row?

I tried Rows.Add() but got a message that's not supported when the
DataGridView is databound... :-(

Steven
