    - Hosting Custom Control in DataGridView Hi All, I am trying to host a foreign control ( may be a usercontrol or some other control like a as tabcontrol ) as one of the columns of DataGridView. As per my knowledge, I derived two classes: DataGridViewUserControlColumn: DataGridViewColumn, DataGridViewUserControlCell : DataGridViewCell I have reached to a point where I can display the column on the DataGridView and each cell has a usercontrol. But when I scroll the DataGridView, the usercontrols fail to scroll or change position. They remain where they are. I am guessing that I haven't derived my two classes well ? Any code sample will be of great help. Below is my sample code that I was working around: ----------------------------------------------------------------------------------------- using System; using System.Windows.Forms; public class CalendarColumn : DataGridViewColumn { public CalendarColumn() : base() { } public override DataGridViewCell CellTemplate { get { return base.CellTemplate; } set { // Ensure that the cell used for the template is a CalendarCell. if (value != null && !value.GetType().IsAssignableFrom(typeof(CalendarCell))) { throw new InvalidCastException("Must be a CalendarCell"); } base.CellTemplate = value; } } } public class CalendarCell : DataGridViewTextBoxCell { private Button btn = new Button(); private static int counter = 0; private int thisButtonCount; public CalendarCell() : base() { // Use the short date format. this.Style.Format = "d"; counter++; thisButtonCount = counter; this.btn.Text = thisButtonCount.ToString(); } public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle) { // Set the value of the editing control to the current cell value. base.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle); CalendarEditingControl ctl = DataGridView.EditingControl as CalendarEditingControl; ctl.Value = (DateTime)this.Value; } protected override void Paint(System.Drawing.Graphics graphics, System.Drawing.Rectangle clipBounds, System.Drawing.Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts) { //throw new Exception("The method or operation is not implemented."); base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts); btn.Size = cellBounds.Size; btn.Location = cellBounds.Location; this.DataGridView.Controls.Add(btn); } public Button GetControl { get { return btn; } } public override Type EditType { get { // Return the type of the editing contol that CalendarCell uses. return typeof(CalendarEditingControl); } } public override Type ValueType { get { // Return the type of the value that CalendarCell contains. return typeof(DateTime); } } public override object DefaultNewRowValue { get { // Use the current date and time as the default value. return DateTime.Now; } } } class CalendarEditingControl : DateTimePicker, IDataGridViewEditingControl { DataGridView dataGridView; private bool valueChanged = false; int rowIndex; public CalendarEditingControl() { this.Format = DateTimePickerFormat.Short; } // Implements the IDataGridViewEditingControl.EditingControlFormattedValue // property. public object EditingControlFormattedValue { get { return this.Value.ToShortDateString(); } set { String newValue = value as String;

    - Opening a form without focus HI, I have a requirment where in I have to show a child form without losing the focus of the invoking form/mdi form. My application shows a Popup window rising from the task bar. This popup form is invoked by the main MDI form which handles several events from the server. Based on the event type I create an instance of the popup form and show the Popup form. During this period the MDI form loses its focus. Once the Popup goes down, the MDI form regains focus. I have used ShowWindow(this.Handle, 4) API call which in turn is supposed to open a form without focus. But still this does not work. Is there anybody who can suggest me the solution for this problem. Any help/suggestion is hightly appreciated. Regards, Hitesh hiteshsalian@yahoo.co.in Tag: TabDialog events Tag: 93405

    - Count string Hello, I have a unique problem that i'm hoping someone can help me with. I have a database that has the following data in a field: 5564564000005450015845456456454540015845456456499900158 If you look closely the string "00158" is listed 3 times. This is just an example, it could be listed either one time or a hundred times in this one field. I need to write some code that loops through each instance of the string and counts the number of times the value "00158" appears. I'm at a loss. Does anyone have any thoughts? Thanks. Richard M.

    - add icon to resource and use different sizes Hi, In my VB.NET 2005 application I want to reuse several icons in different sizes. My icons contains images of 16x16, 24x24, 32x32 and 48x48. The problem is: I doesn't always use the right size: sometimes it resizes the 48x48 image to 16x16 instead of taking the 16x16 image. Is there a way to specify which image of the icon has to be used? Thansk a lot in advance, Pieter Tag: TabDialog events Tag: 93402

    - Determining parent form of Component Hi all, I have a component (originally developed as a class) that handles the processing of window docking. When implemented as a class, I simply passed the form (which implements ContainerControl) into the constructor. I expected that, in implementing a Component I would be able to determine the form on which the component was added without having to have it passed in as a parameter in the constructor (or as a writable property). Have I missed something (probably!)? How would you go about determining the form on which a component resides? Regards, RM Tag: TabDialog events Tag: 93388

    - Mixing GDI & GDI+, ok while drawing, big problem for print preview, small problem while printing I have some Control/Canvas which renders its shape with GDI+, but render (styled, international) text with Uniscribe/ScriptTextOut/GDI. To be sure everyting was right I also underlined the text with a GDI red line (MoveToEx + LineTo) Everything run well in the application. The problem arise when I try to print. - 1st problem, in print preview: There is no text at all! coordinate are allright as I could see the red line, but no text :-/ Out of curiosity I tryed to write a X with TextOut() and it displayed allright (i. But I can't used TextOut(), I'm using Uniscribe and all I've got at the drawing stage is some glyphs. Any ideas? Also, 2nd problem in both print & print preview: I set the coordinate with SetWorldTransform(), using the matrix coming from e.Graphics.Transform. But that's not quite right. I have - screen: e.Graphics.DpiX = 96, GetDeviceCaps(screenHdc, LOGPIXELSX) = 96 - printer: e.Graphics.DpiX = 300, GetDeviceCaps(screenHdc, LOGPIXELSX) = 300 And I should scale the coordinate by "3" to have the right result. Exactly 3, not (300.0 / 96.0) = 3.125 I tried something like that while printing & print previewing: ::SetMapMode(hdc, MM_ANISOTROPIC); ::SetWindowExtEx(hdc, 96, 96, NULL); ::SetViewportExtEx(hdc, 300, 300, NULL); ==== And it was not right, I had to write instead someting like: int val = (300 / 96) * 96; (integer multiple) ::SetMapMode(hdc, MM_ANISOTROPIC); ::SetWindowExtEx(hdc, 96, 96, NULL); ::SetViewportExtEx(hdc, val, val, NULL); Any idea what's going on?

    - Using UserControls and generics with VS2005 designer Hi, I am currently experiencing some problems in designtime using a UserControl that uses generics. I have defined a lot of UI components that all inherit from a common UserControl (for common functionality). I wanted to define a property, Value, that would be common for all inherited controls but would reflect what kind of "value" the specific inherited control implemented. My initial thought was to use generics and define the base class as this: public abstract partial class EnhancedBase<TValue> : UserControl This class would define the Value property as this: public abstract TValue Value { get; set; } And I would override this for all the inherited UserControls. Now, I did already have a different implementation of this, and simply modified all my classes to use this technique - after a while(the project is pretty large..) I discovered that the inherited (but not the baseclass!) UserControls would not display at design time in Visual Studio 2005 beta 2 at all. All I get now is the red-and-grey error report saying the designer could not find any controls to display. It specifies the base of my controls and I have checked that fuslogvw does not report a missing assembly binding. After this I was not able to create a new Inherited UserControl based on my baseclass using the wizard - it reports that it cannot find any inheritable classes in the assembly containing the base class. The code seems to run fine at runtime - its just the designer that is unable to show the controls that are using generics. I can't find any mention of this anywhere - any insight? Also; I would like to make my usercontrols show up in a specified category in the toolbox, kind of like [Category("Custom")] works for a properties and event in the other toolbox. I though I was to use [DesignerCategory("Custom")] but this does not seem to do anything. Cheers! Tag: TabDialog events Tag: 93379

    - NumericUpDown Hi, I have a form with a TextBox and a NumericUpDown on it. NumericUpDown's CausesValidation is true. I subscribe for NumericUpDown.ValueChanged. I experience the following problem: If I change the value from arrows, the ValueChanged event is fired as expected. If I enter value in NumericUpdown from keyboard (not arrows) and I press ENTER, the ValueChanged event is fired as expected. If I enter value in NumericUpDown from keyboard (not arrows) and I simply move the focus to the text box by pressing TAB or simply clicking on the text box with the mouse the ValueChanged event is NOT fired. Is this behaviour as expected? How do I get notification when the value gets changed no matter how? I also noticed that when I change the value of NumericUpDown from from keyboard (not arrows) the event is not fired but if I change from arrows after that, the event fires twice Thanks Tag: TabDialog events Tag: 93373

    - Setting a form.Owner from a different thread in .net 2.0 Hello, I have an splash window application that creates a form from one thread (call it formSplash) and runs it and later on a differnt thread a new form (mainForm) is created and I want to make mainForm the owner of formSplash so that it appears behind. Using VS2003 I was able to do this by simply setting the Owner member of the splashForm from the mainForm thread. With .net 2.0 I get the following error: Cross-thread operation not valid: Control 'formSplash' accessed from a thread other than the thread it was created on. I then used formSplash.Invoke to call a method that would set the variable and passed it the mainForm as a parameter but when I assign it to the Owner member variable I now get the following error: Cross-thread operation not valid: Control 'mainForm' accessed from a thread other than the thread it was created on. I hope I was able to explain the problem correctly... Thanks Jeronimo Tag: TabDialog events Tag: 93371

    - Windows Forms controls hosted in IE Hi I have a Windows Form control create in .Net 1.1. We are having an interesting problem with the control and some interactions with the server it is hosted on. We've recently upgraded one of our Production Servers to Windows 2003 SP1. Our old server as well as our development server are running Windows 2000 SP4. After the upgrade we found that most users could not access the control on the new production server. Accessing the old server or the development server will allow the users to access the control. I don't believe it is any code issue as the control still works using the old server. (I have strong named the control and set the APTC bit so that should not play into this.) The only thing that is different is the server is the update OS. Also, there are people that actually can access the control on the new server and their rights are not anything different than others. I've also tried just a generic control (using the sample in MSDN) and that does not work for the majority of our users as well. Does anyone have any ideas what we can do?

    - Exposing usercontrol components at design time Hi, I want to allow design time modification of components on a usercontrol. I added a listview called listView1 to the usercontrol, then added this accessor method: [Category("Components"), Description("Set the listview parameters."), DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public MyListView ListView { get { return listView1; } } This works great, almost. When the usercontrol is added to a form, I can edit the ListView properties. Unfortunately, this line of coded is added to my form's InitializeComponent() method: this.userListView.Controls.Add(this.listView1.ListView); I've read that usually you have to expose each property individually, but exposing the entire control works except for the redundant "Add" above. And with DesignerSerializationVisibility.Content I didn't expect the control itself to be serialized, just the contents. If I delete the line above everything is fine, but of course I don't want to have to edit InitializeComponent(). Is there a way to eliminate the redundant listview "Add()"?

    - MessageBox clears my splash screen Hello, I am opening a messagebox on top of a splash screen. The splash screen is a normal windows form with(FormBorderStyle=None, StartPosition=Center and TopMost=true). My problem is that my MessageBox is clearing the splash form behind it. When I press OK on the message box, the splash form is all gray(the background color) and no controls are visible. I have tried to set up a timer on the splash screen, and when the timer kicks in, the form is visible and it does not help to call neither Update og invalidate on the form. The only thing that helps is if I call Hide() and Show(), then all my controls are visible. I call the messagebox with the owner window, but there is no difference. Any ideas? Thanks Henrik.

    - Message loop question Hi, Could someone explain to me why this doesn't work? (VS 7.1, .NET 1.1) Thread A: Application.Run(); Thread B: myForm.Show(); If I run both on the same thread it works. I thought that it was enough to have a message loop running on any thread in the application to make forms work, but apparently not. Why? If I change the code in thread A to Application.Run(myForm); the form works. Why? I thought the only difference would be that the message loop would now exit when the form closes. If I change the code in thread B to myForm.ShowDialog(); the form also works. Why? -- Patrik Rådman patrik at iki dot fi http://www.iki.fi/patrik/ Tag: TabDialog events Tag: 93351

The result was something silly like this: dim tn as new treenode("mytext") .. tn.nodes.add(tn) This didn't throw an exception but rather (i assume) recursively looped and hung the application on a test debug and run. Does everyone else get this kind behaviour? And if so why doesn;t it throw an exception? Treeview is a UI control. Its impossible to draw this kind of behaviour....at least in this dimension anyway.

    - VS 2005 Internet Connection Hi, I am using VS 2005 - BETA 2. I'd like to use My.Computer.Network.IsAvailable to detect whether an internet connection is available. Is this the best "new" way of doing things or does the above method above detect network connectivity of some other type? There seems to be a delay capturing the disconnect-connect events when I do use it, is there a way to shorten this delay? In essence, what does this method wrap? Regards, Giovanni P.

    - Text Box Validation - prevent a blank entry Hi, I have a form with several text boxes on it. Each test box requires some validation ... for being numeric etc. and I am successfully using the Validating and Validated events of each text box and an ErrorProvider to achieve this... However, I want to validate one of the text boxes such that the user *must* enter a value... ie. the text box must be non-blank. I tried putting code in the Validating event to disallow a blank value.. this did not work. The problem is that the Validating event is only invoked if the text box gets focus. If the user never clicks on the text box, then me error is never displayed. How do I force this validation .. even if text box never gains focus ? Many thanks. Tag: TabDialog events Tag: 93326

    - TreeView and SetScrollInfo problem Hi, I have a WinForm with a TreeView and a custom scrollbar that is positioned over (hides) the TreeView's own ScrollBar. I use SetScrollInfo to update the TreeView's ScrollBar to match the changes in the custom scrollbar. The problem is that while the TreeView's ScrollBar does move to match my custom scrollbar, the contents in the TreeView doesn't move at all. Any suggestions? Tag: TabDialog events Tag: 93322

    - Printing the entire UserControl - as is.. Hi, In my windows application, I have a form and I placed an UserControl on the form. I placed lot of edit controls on the UserControl. Is there a way to print the entire UserControl just as it appears on screen? This is something similar to Print Screen functionality, which captures the whole screen as an image. But I want to capture just part of the screen, which is usercontrol. If the usercontrol has scrollbars, I want to include the hidden portion as well in the print functionality. Basically, I want to have a button on the form with a caption "Print Page", that should capture the entire UserControl as an image including any hidden scrollbar region and send it to the printer. Is this possible? Any ideas.. Thanks, Raj Tag: TabDialog events Tag: 93320

    - Add controls to taskbar (like Google Desktop Search box) I was wondering if there's any way to create a toolbar that docks on top of the windows tast bar and shows up in the "toolbars" list. I noticed that Google Desktop Search has an option to add a search box to the taskbar (fully dockable/floating etc), so it looks like it must be possible, but I haven't been able to find a way to do it. The closest I came was a sample ApplicationBar, but this could only dock over top of the taskbar, not "inside" it. Ideally, I'd like to create something similar to what GDS has, which is selectable from the context menu, and which can be used in either a "docking" or "floating" mode. Is there any way to do this? Thanks in advance for your help! Chris Tag: TabDialog events Tag: 93319

    - ClickOnce server deployment for Intranet App I am trying to use ClickOnce Deployment technology. I have published it on my System(Test Machine) and it works great. Now I want to put it on the main web server which I cannot access from my machine. So I copied the files from the Inetpub\wwwroot\ directory to the main server . But when I run it from the main webserver it tries to run from where I made it(test machine). My question is, what I have to do to run it/deploy it to different machine. We need to put it on our client intranet server also and they all have different server name. Thanks in advance. Mike Tag: TabDialog events Tag: 93313

    - ComboBox autofiltering items - using RowFilter Hi guys! I need a help from you. I would like to do an autofiltering ComboBox. There is a ComboBox as DropDown style and its items come from a DataView. Well, when user types on that control (Text property) it should filter the rows inside using the DataView.RowFilter property and, in the same time, shows to user its items (DroppedDown = True) already filtered. I've tried the following: Private Sub ComboBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles ComboBox1.KeyUp Dim strRowFilter As String strRowFilter = String.Concat("Name LIKE '%", ComboBox1.Text, "%'") DataView1.RowFilter = strRowFilter ComboBox1.DroppedDown = True End Sub As you can see, when the users types on ComboBox's Text property the event KeyUp is raised. Then, its Text content becames a Filter string, eg. "John" goes "Name LIKE '%John%'" and that string to RowFilter. My solution for this issue isn't working. When I type the Text I can se the items but for just the first letter. Thanks in advance. Tag: TabDialog events Tag: 93306

    - Get rows as shown on DataGrid (WYSIWYG) Hi, How do I get DataGrid to return all the rows that are currently displayed on the screeen as seen by the user (WYSIWYG). The main requirement is the users can scroll up-or-down the grid, and refresh (retrieve the latest data from the database) the rows as seen by them by clicking a "Refresh Shown Rows" button. However they do not want to select any particular row (therefore I am unable to use any of the "Selected" functions). The DataGrid is binded to a DataView, which in turn is binded to a DataSet. The DataGird has a fixed height, showing 12 rows at any time. Therefore at any point of time I just need to refresh the 12 rows as seen by the user. Pls kindly advise. TQ.

    - Interfaces with vb2005 project Hi, I am developing a windows project. In one of my form I have few procedures and functions. Everything is working great. Now I am told to do it through interfaces, means create a interface class and then implement it. I am little concern doing it. 1. Do we really have to create a interface when we have to implement it ONLY in one class nowhere else. 2. Are there any performance issues when we are using interfaces methods instead of method with not interfaces implement. Also I want to know when is the right time to use Interfaces.

    - VSTO modal form question Hello I'm working on a Microsoft Word VSTO (Visual Studio Tools for Office) project (2003). The 'host' Word document has a custom command button which brings up a Windows Form via the following (C#) code private void RunScript_Click( Office.CommandBarButton Ctrl, ref Boolean CancelDefault ) { __pyScriptForm = new PyScriptForm( this.ThisApplication ); __pyScriptForm.Show(); } where 'ThisApplication' is of type /Microsoft.Office.Interop.Word.Application/. This form is used to run scripts written in Python, capture their 'StdOut', and write it to the underlying document. This works as I want - as the script runs, the output appears on the document below. However, I think it would be preferable if the form were shown modally - the document shouldn't be accessible while a script is running, and there's a Cancel button on the form that will stop the script. But if I do this ( with ShowDialog rather than Show ), then the written output doesn't show up until the Form is closed. It's more satisfactory if you get the data appearing right away. Can I have my cake and eat it with this - ie. have a modal form, but also see the script output? TIA G.F. Tag: TabDialog events Tag: 93289

I recently upgraded to RC1. The problem: When building the solution in Beta 2, the toolbox would automatically update by adding all custom controls from all projects found within my solution. In RC1 this is no longer the case. Custom controls simply do not show up. Even if AutoToolboxPopulate is true. Anyone had this problem and found a solution? Any help would be greatly appreciated.

I have treeview with items. When an item is clicked a tabDialog control
appears. The user might decide to update the data in the TabDialog control.
When they are done I would like to catch the event and see if I need to
update the database.
Which event in the tabDialog should I use? Is there an event in the tabPage
that is better for this?

"tabDialog" = TabControl?

Yes, I mean tabcontrol. I am starting to understand that I need to look for
one of the events on the tabpage instead.
