    - grid component similar to Excel Hi all I need a suggestion. I have a customer that wants the grids in the application i'm going to develop lokoking as much as possible as Excel grids. I suppose he wants the filtering possibilities of Excel in the header of the grid, the possibility to copy&paste from one cell to the other etc. My question is: is there any component that can suit my needs? something that someone used/has used for large scale apps? Please give me a suggestion! Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100736

    - How to control date format in combo Hi All, This SHOULD be simple, but I just can't see it... I have a combo box which uses a dataset as its list source. The displayed member is a date column from the underlying table. When I run it, the date in the combo is formatted as d/m/yyyy hh:mm:ss, which I don't want - I just want the date part. How can I control the format of the date? Do I have to delve into owner-drawing? Surely not! Thanks Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100730

    - 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.

    - Newlines in TextBox I'm trying to programatically add new lines to the content of a (System.Windows.Forms.)TextBox and, while I have found a solution, I feel that it can't be very efficient. There must be a better way. I first tried: textBox.AppendText( "\n New line" ); But that didn't work. Nor did variations on the theme, like textBox.Text += .... 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. Am I missing something here? -- T Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100724

    - Problem with ServiceController.ExecuteCommand Running ServiceController.ExecuteCommand on my custom service raises a "Cannot control service on machine <machineName>". Drilling thru the inner exceptions, I come across an "Access is denied" error msg. Funny thing is I can start and stop the service using the same ServiceController instance, so an issue on permissions seems remote. Service originally runs under LocalSystem; changed it to my Windows account but had no effect. Any help will be greatly appreciated. Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100718

    - 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?

I found it works fine for the rows that already exists in the datasource which bound to DataGrid, but for the new added row, after I set the value and click the mouse to other row, the value of the new row dispears. Seems that it can't add row & set value for new row. Does anyone could help me for this ? Thanks! -- Do or do not, there is no try. Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100693

    - Need *formatted* value from DataGrid...possible? Hello, all. I have a Windows Forms app with a datagrid control, with several custom column styles applied. One of the columns holds a decimal data type, with a format string of "C" for currency, and this works precisely as intended, eg the value 1234.56 is formatted as $1,234.56. In another portion of the application, I need to get the *formatted* rendering of that value from the grid. I've tried the simple grid[row,col] syntax, but it merely returns the underlying value, but I need the resultant value after the column style is applied. My ultimate intent is to measure the width of the formatted string to autosize the width of the column, and what I have now only formats the raw data, and that won't work. Is what I need even possible? I've gone through the DataGrid FAQ and MSDN and not found what I'm needing, so I'm turning here for help. Many thanks in advance, -intrepid Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100688

    - MC ++ reference types and their scope Hello, I'm back from some old fashioned project and something has changed in comparison to my first hours of programming in Visual C++. I'm up to build a tool and started by means of the Express Edition 2005 of VC++ aka VCM++. I decided to use the advantages of Managed Code but I'm wondering about the designer generated code. It's a Windows Form App. I use Managed Strings and other built in types. My question is if I instantiate an object of type Int32 or Double or String have I order to delete such objects explicitly or is GC doing it. As I can see the code designer doesn't add code to order to destroy such objects explicitly but for one it is doing it. System::ComponentModel::Container ^components; and in the destructor if (components) { delete components; } As I read all members will be implicitly destroyed when they come out of scope. Does this also include the reference members? I read some articles from the msdn mag and know how the finalize mechanism works but I'm just unsure since as I started to program I used the old new, delete mechanism which is obsolete now. Please let me know what can I do to avoid misdesigns. May be it's to basic for the good old programer on this thread but please help. Thanks in advance.

    - Specifying Parent to a Windows Form Where Parent Form is in VB 6 I have built a class library in Visual Basic .NET 2005 that exposes a class as a COM class using the ComClass attribute. This COM class allows (among other things) loading a Windows Form. I am using this .NET class library from Visual Basic 6 as if it were a COM DLL using the new features of Visual Studio 2005. The Visual Basic 6 application contains an MDI form. I can load the Windows Form contained in the .NET class library from Visual Basic 6 by means of the COM class exposed. This works fine as long as the Windows Form is loaded as a non-child form. The problem is that I want the Windows Form to be loaded as a child form of the Visual Basic 6 MDI form. How can I specify to the .NET Windows Form that the parent form is a form in Visual Basic 6? Thanks in advance! Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100675

    - VS2005 Opening a Form in Designer Sets the Modified (Dirty) Indica I have project that has forms derived from another form in a class library. I just converted this project to VS2005 from VS2003. Whenever I open one of the forms the tab showing the name of the form with an asterisk (*) so that it appears like it is modified without me making any changes. When I click the close button it then asks me if I want to save the changes? If I say yes and compare the before and after there is no difference. Has anyone seen this? I'm assuming it's probably being caused by something in my base class (form) but I have no clue what it could be. Any help is appreciated.

    - Handling Different DPI Settings when Manually Setting Coordinates If I'm manually setting the size and position of controls, how do I determine what the coordinate should be if the user changes the windows DPI setting? I have a problem when I run an app, which was compiled in 96 dpi, in 120 DPI. I have the property, AutoScale, set to DPI. If I manually set the size and position of any one control and get it to show up where I want in 96 DPI, the control shows up in the wrong place under 120 DPI. Since the DPI is higher, the X and Y coordinates should be higher as well. I know how to detect the DPI setting. So how do I know what values to use based on the DPI setting? Can I just multiple all manual coordinate settings by 1.25 if the DPI is 120? I'd like to take advantage of the Autoscale property, but I'd like to just change the position of one or two controls depending on user bevahior. Is this something built in or do I have to come up with complex spacing algorithm? Ed Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100657

    - Embedded Winform resize in 2.0 I have a no-touch application which I created in 1.1. It is embedded within IE, not a stand-alone window. I'm migrating it to 2.0 and one thing (which is a major problem) is that the <object> tag doesn't appear to resize within the browser frame any more. I tested the same code in 1.1 and 2.0 and something changed. I need to figure out how to change the size of my application when the browser changes. I've tried a bunch of options including JavaScript but nothing appears to effect the size of the embedded .net control. Anyone have any ideas?

    - Application.Restart on ClickOnce Deployed Application We've got an application that we deploy with click once. Using the MyApplication_UnhandledException we restart the application with Windows.Forms.Application.Restart() if the user encounters an error we didn't catch. Our application allows paramaters to be passed to the ClickOnce Application We are retrieving these like this.. If My.Application.IsNetworkDeployed Then Dim zUri As New Uri(My.Application.Deployment.ActivationUri.AbsoluteUri) zstrQuery = zUri.Query zarr_strArgs = zstrQuery.Split("&".ToCharArray) Else.... This works fine when the appliciation is started the first time. After a restart though, it appears that there is no ActivationUri.AbsoluteUri and I recieve an "Object reference not set to an instance of an object" error. What's going on? The documentation states, "Applications are restarted in the context in which they were initially run. If your application was started using a URL pointing directly to the application's main executable file, it will be restarted using the same URL. If your application is a ClickOnce application, it will be restarted using ClickOnce. If your application was originally supplied command-line options when it first executed, Restart will launch the application again with the same options." The way I read this, it should activate the same way it did the first time, so why is there no Uri? -- Neil Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100643

    - MdiParent bug...or am I dumb Setting the MdiParent of a Form works as expected. However, if an application has more than one top level mdi container form then unexpected erroneous behavior is observed when setting the MdiParent of a child form first to one MdiContainer, and then setting the MdiParent of the same child form to another container. After setting the MdiParent for a second time, the child will not activate and when maximized will not merge with main menu, if available, or the title bar if there is no main menu. Reproduce with the following code: using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; namespace MDIParentBug { class MainForm : Form { Form secondMdiForm = new Form(); Form mdiChildForm = new Form(); public MainForm() { this.Text = "Main Mdi Form"; secondMdiForm.Text = "Second Mdi Form"; //Set as mdi containers... secondMdiForm.IsMdiContainer = true; this.IsMdiContainer = true; //set the mdi parent of the child mdiChildForm.MdiParent = this; //Show second mdi container... secondMdiForm.Show(); //Hook up activated events.. this.Activated += MDIParent_Activated; secondMdiForm.Activated += MDIParent_Activated; //show mdi child... mdiChildForm.Show(); } void MDIParent_Activated(object sender, EventArgs e) { //set new parent of mdi child... mdiChildForm.MdiParent = sender as Form; } [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } } I'd like a simple fix but unfortunately I think it's truly a bug. One that's unfortunately killing my schedule. If I'm doing something fundamentally wrong I'd like to know. Robert Conde Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100634

    - External component has thrown an exception I seem to get this exception when I open forms using ShowDialog() from event handlers. Consider the following: private void cboCombo_SelectedIndexChanged(...) { try { (do something that raises an exception here) } catch(Exception ex) { try { (open a form with ShowDialog() here) } catch {} } } Somehow the SEHException is being thrown to Main() where it crashes the app. The stack trace is as follows: at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at WinApp.MainForm.Main(String[] args) in mainform.cs:line 2078 I've gotten around this issue in the past by starting a timer in the event handler, and then launching the form from the timer elapsed event. That works ok, but gets cumbersome quickly. I can provide code samples if necessary, but the code in question really isn't doing anything spectacular. I don't see how the code sample above could allow an exception to be thrown (without an explicit throw, that is). Does anyone have any experience with this issue?

    - Does ClickOnce work well? Any disadvantages to it? We have an ASP.NET web application that gets installed on a server in a hospital and then any computer throughout the hospital's network can access the application. I prefer Winforms applications to ASP.NET, so I am thinking that we should replace our current one with a Winforms application distributed through clickonce. What are the disadvantages of doing this? I am having difficulty convincing my coworkers that clickonce will distribute just as easily as a web application. It seems to me that the only major disadvantage is that the client PC has to have the .NET framework on it, which won't be the case in general. Does clickonce work really as easily as advertised? I scanned newsgroups to see a bunch of people having deployment problems of one type or another with it. thanks in advance Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100628

    - newbie... tablestyle question... I am using vb .net 2002. I have a datagrid where I am displaying columns from a table. The columns that are empty are being displayed as "{null}" and I want them to be just blank. I heard the onl;y way to do this was by using a table style to map each column and use the .nulltext="" property so that nulls are displayed as blank... My question is this... There are many columns in this particular table that have null values. Is there a way to set up a table style using a loop to go through eac field in the table (we are using SQL server) and set the field arccordingly?? I am currently doing it the long way and I am pretty sure there is a smarter way to do it... Below is some sample code for the load event of the form... In this code I have only dim'd two columns but I have a bunch. There must be an easier way than what I am doing here. I am think a for next loop must work but what would the syntax be? Private Sub frmAssetMaster_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim ds As New DataSet() Dim dgTableStyle As DataGridTableStyle ' fill the dataset SqlDataAdapter1.Fill(ds) Me.DataGrid1.DataSource = ds Me.DataGrid1.DataMember = "ComputerMaster" 'Create a data grid table style. dgTableStyle = New DataGridTableStyle() 'Map the table style to a table dgTableStyle.MappingName = "ComputerMaster" ' Dim all of the columns you want Dim dgTextBoxCol As New DataGridTextBoxColumn() Dim dgTextBoxCol2 As New DataGridTextBoxColumn() ' Set Col 1 properties dgTextBoxCol.MappingName = "ComputerName" dgTextBoxCol.NullText = "" dgTextBoxCol.HeaderText = "Asset Name" 'Set Col 2 properties dgTextBoxCol2.MappingName = "RAM" dgTextBoxCol2.NullText = "" dgTextBoxCol2.HeaderText = "RAM" ' Add the column styles dgTableStyle.GridColumnStyles.Add(dgTextBoxCol) dgTableStyle.GridColumnStyles.Add(dgTextBoxCol2) ' Add the table style Me.DataGrid1.TableStyles.Add(dgTableStyle) End Sub Tag: ErrorProvider in Datagrid with Comboboxcolumn Tag: 100625

    - Word in a WinForm I'm struggling to embed a word document in a winform application and access the document object to automate it. I've found http://support.microsoft.com/default.aspx?scid=KB;en-us;304662 But the code won't compile. There seems to be some conflict between the Browser control and the SHDocVw bits. I can get the document loaded OK, but the event mentioned in the KB article does not seem to exist and I can find no way of getting at and binding the instance of the document to a Word._Document object. I can't find anything particularly useful through google and to make matters worse, I'm using an x64 OS which may well be having issues with 64/32 bit widths (though I don't think I've got there yet). So, simply put. In VS2005 I can load a word document in to a browser window. How do I get teh Word Document object from it?

Hello,
I have got a Datagrid containing a Datagridtablestyle which is a
comboboxcolumn derived from DataGridColumnStyle. When validating my datagrid
the error icons appear but the tooltip does not appear. Not having a
comboboxcolumn everything is fine.
My first idea is to implement the IDataErrorInfo interface in my
Comboboxcolumn but there is no effect! Can anybody help me?
Thanks
