    - dataGrid - Detect new row being added and prefil columns with data I want to detect when a new row is added to my datagrid. At that time I want to fill all the columns with some initial values before the user gets to start editing them. These values are not always the same, they will dpeend on who is using the program at the time, the machine they are on and variuos other factors. Because of this I cannot use the solution that assigns default values to all columns Any ideas? RichardF Tag: Bastardized TabControl Tag: 88211

    - Don't use the object: ActiveForm unless you check it for null each Don't use the object: ActiveForm unless you check it for null each time you do. This object is in my opinion flawed and not all that useful since it becomes null when the form loses focus. I am posting this warning lest you too fall into the trap of using the ActiveForm.refresh() method instead of the tnis.refresh(); method. They are not the same and you may or maynot find your program crashing because you did not first check each time you call the refresh method associated with the object again try not to use ActiveForm object and instead use the this object of the form or the actual form itself. I think this is a bad design for ActiveForm object. Bottom line is do not use it unless you are absolutely forced to. Instead use the this.object Here is the original error message I ultimately solved: System.NullReferenceException: Object reference not set to an instance of an object Tag: Bastardized TabControl Tag: 88209

    - ANN: Advanced auto-layout panels plus XAML-style interpreter for 1.1 We have released a library containing a couple of automatic layout controls targetted at .Net 1.1 similar to the the FlowLayoutPanel and TableLayoutPanel in Avalon. Also packaged with these are a basic XAML-style interpreter which works well with existing Windows.Forms controls. These are useful for: - creating resolution-independent applications (especially for those who are long-sighted) - internationalisation (automatic static text translation included in the interpreter) - allowing you to create central visual style rules for an application via XSLT processing of XML script files.

    - Creating a localized control In my application, I am providing a plugin capability by using an interface to specify what the plugin should do. One of the functions is 'CreateConfigurationControl' which returns a UserControl. I am now trying to localize the application, and I'm setting the Thread.CurrentThread.CurrentCulture and CurrentUICulture objects as the very first thing in my Main(). The forms that are created normally are all appearing as their localized versions, but the control that I receive from the CreateConfigurationControl is not, even though there is a localized version defined. In order to actually create the control, I've tried a simple 'new ConfigControl()' and Activator.CreateInstance, passing Thread.CurrentThread.CurrentUICulture to the appropriate version of CreateInstance(Type, BindingFlags, Binder, object[], CultureInfo), but I still get back the default English version... Any suggestions on what I might be doing wrong, or if there is an easier way to guarantee that I get back the correct localized version of my control? -mdb Tag: Bastardized TabControl Tag: 88203

    - MeasureString() and ClearType Hi all, When I draw a string with TextRenderingHint.ClearTypeGridFit the width of the drawn string is wider than what is returned by MeasureString. I had hoped that setting the TextRenderingHint prior to calling MeasureString would solve this, but it did not. Any ideas on how to get the actual width of the drawn string when using ClearType?

    - Login windows -> Child form, strange behaviour on minimize Hi all, I've got a typical windows form application with a login form, when I login, the login form will be hidden and a new window will appear. For this, I'm using .Show() method, and not .ShowDialog() because there's a chance of reloading a different ini file during login and I want to allow the user to reuse the login form (and it's credentials), and when the user reloads the login form will became visible and the the other window will became hidden. If he really tries to login again then I will kill the new window and create a new one. This all works fine, the problem happens when I try to minimize the login form, a small box appears in the left corner just like a mdi window when we minimize it on the main form. I would like for this "box" not to appear, and the form simply disapears and when I press the on the icon of the taskbar the window would appear again, just like any windows form application. Any help? Thanks, Luis Miguel Pinho Tag: Bastardized TabControl Tag: 88197

    - Add image to a control...reposted from languages.vb I originally asked this in languages.vb, and someone there suggested I post it here instead. The requirement I've been tasked with is to have a textbox that has an image in it (a magnifying glass) always on the right side of the textbox, but still in the edit portion. The image should be BEHIND the text, and if clicked on then would fire an event. The suggestion I got from the other group (Carlos J. Quintero, the illustrious maker of MZ-Tools) was to make it an ownerdrawn textbox. He said that all I'd probably need to care about would be the paint event and the click event. In VB6 I'd subclass the textbox and watch for the WM_PAINT message, but in .Net I have NO idea where to start on this. Can someone point me in the right direction? Thanks.

    - Localization question I'm writing an application that needs to be localized into German. I've set the Localizable to 'true' and the language to 'German' on my form. I've translated all of my controls. However, I have a UserControl on my form (which I have also localized to German) but the designer still shows it in English. I have recompiled so I know that the designer should know about the localized version of the UserControl. Is this the expected behavior, or should I see the localized German version of my UserControl as well? Also, is there any way I can specify on startup what language I want to use? I'd like to run my program in "German mode" to make sure I haven't missed anything. Thanks! -mdb Tag: Bastardized TabControl Tag: 88188

    - RichTextBox - beeping I am programatically adding blocks of text to a RichTextBox control and it constantly "beeps" when doing so. The program is reading an xml file line by line and when it finds certain attributes it changes their values to a different color. This means that a line of xml might have its color changed several times. I thought it had to do with the changing colors but when i commented that code out it still beeped. If i write the entire line without substringing it together i get no beeps. It only seems to happen when i break the line up and substring it back together. example: the True part will beep but the false part will not. Color changing has been omitted since it's not a factor. if (true) { rtb1.SelectedText = line.Substring(0,10); // originally set color to black rtb1.SelectedText = line.Substring(11,10); // changed color to red rtb1.SelectedText = line.Substring(21,10) + "\r\n"; // changed back to black } else { rtb1.SelectedText = line + "\r\n"; } Anyone know why this happens and is there a way to stop it?

    - Multithreaded WinForms question My application's form is handling an event raised from a worker thread in another object. In the event handler I want to call a sub procedure that does a number of things and among those things is accessing controls on the form. This sub procedure normally has been called from the Click event procedure of a button on the form so there haven't been any issues with accessing controls from outside the UI thread. Now I have to consider this. I could create delegates for all the procedures I need to Invoke on the controls but I was hoping there was a simpler way. Is there any way to force the UI thread to call a sub procedure without using Control.Invoke ()? For example: Private myObj As MyObject Private Sub MainForm_Load ... ... AddHandler myObj.SomeEvent, AddressOf MyObject_SomeEvent ... End Sub Private Sub MyObject_SomeEvent(ByVal whatever As Integer) ' SomeEvent is raised by a worker thread in MyObject. ' How can I force the UI thread to call SomeProcedure ' from here so I don't have to litter the SomeProcedure ' Sub with If...Then...Else structures testing ' Control.InvokeRequired() and calling Control.Invoke() ' with various custom Delegates that I have to create? End Sub Private Sub SomeProcedure(ByVal whatever As Integer) ... Do Stuff SomeTextBox.Text = "Gooney Goo Goo" ... End Sub Hopefully I'm making sense here. I may be a little confused and not realize it yet. Joel Moore Tag: Bastardized TabControl Tag: 88185

    - Control OnMouseDown and OnMouseUp called twice - surely a bug? I'm noticing strange behaviour with System.Windows.Forms.Control. If I press the mouse (left button), then move the mouse while still holding it down, and then release the mouse, I get an extra set of OnMouseDown and OnMouseUp. So I get OnMouseDown, OnMouseUp, OnMouseDown, OnMouseUp even though the mouse has only been pressed and released once. Does anyone know about this? I think this is surely a bug. It's easy to replicate. Add this code to a new user control and put an instance of the control on a form. Protected Overrides Sub OnMouseDown(ByVal e As System.Windows.Forms.MouseEventArgs) Debug.WriteLine("OnMouseDown") MyBase.OnMouseDown(e) End Sub Protected Overrides Sub OnMouseUp(ByVal e As System.Windows.Forms.MouseEventArgs) Debug.WriteLine("OnMouseUp") MyBase.OnMouseUp(e) End Sub You might have to try a few times to see it, but it usually only takes a few efforts. It seems easier to replicate if I drag the mouse from the bottom of the control towards the top! Thanks in advance. Tag: Bastardized TabControl Tag: 88181

    - Modeless Form visibible but inivisible PLEASE PLEASE HELP Hi, We have an application which contains numerous ChartFX controls. Basically the user can double click on an existing chart, and it will open a new (modeless) form which contains a new chart. The problem is that the new window although appearing to be the focussed window isn't, as the user has to click on it twice (one click seems to be passing right through to the parent form) before the window is actually selected. This wouldnt be such a big problem except that if the user right clicks on the chart we get a "Cannot display context menu on invisible control" error, even though the control is visible. I guess that basically somehow the modeless dialogue window is not visible to the underlying code, and the events arent firing properly. I have tried everything I can think of to fix it including calling Select(),Activate(),BringToFront() etc on the new window but none of them make any difference. I have even triggered mouse events on the new window to try to focus it automatically. I am pretty much desparate to make this work so Can anyone please help me?

    - Screen.WorkingArea Changed Event? Hi all, First the question: Is there a way to be notified when the WorkingArea of the Screen changes? (for example, the taskbar is moved from bottom to left of desktop) Here are the details of the problem if you are interested. I have a form where I set the Region property. Everything works fine until you move the TaskBar to the left or top of the desktop. This then skews my Region's location and it appears incorrectly. The problem is caused when I translate my Region to the screen coordinates (using PointToScreen and Region.Translate). If the taskbar is on the left or top, the region gets "pushed" to the right or bottom. However, this position is incorrect. I solved the issue by offsetting the region location using Screen.WorkingArea's x and y values. Then I ran into a performance problem. I have to recalculate the region quite a bit and it caused a performance issue. I was using Screen.FromControl() everytime I was recalculating the region (My application must support multiple monitors) and I believe this was the culprit. I have worked around the issue by caching the working area myself and testing if my Form moves from one monitor to the other via the LocationChanged event. The only problem is I need to know when the WorkingArea changes so I can update my cached workingArea and also re-translate my region. TIA Cole Tag: Bastardized TabControl Tag: 88151

    - (newbie) Slow Combobox Binding I'm fairly new to winforms, but I've been playing around with ASP.NET for a while, so I'm familiar with a fair bit of the framework, however I'm having an annoying issue when trying to bind a simple arraylist to a combobox. All I want the combobox to be is a simple dropdownlist and I'll grab the SelectedValue from it to do other stuff elsewhere, so what I thought I could do is : myCombo.DataSource = myArrayList; myCombo.DisplayMember = "Name"; myCombo.ValueMember = "ID"; Where myArrayList is an ArrayList (shock!) of simple objects with the properties "Name"(string) and "ID"(int). (very basically, their class definition is just : public class myClass { myClass() {} myClass(int ID, string Name) { this.Name = Name; this.ID = ID; } public string Name; public int ID; } - it's not quite that dumb, but you get the idea) I'm finding that not only is DisplayMember *completely ignored* (i.e. all the entries in the combobox merely display "myNamespace.myClass"), but the binding process seems to take an inordinately long amount of time - somewhere up to 5 seconds. I thought initially it was a database access time or the size of the ArrayList slowing it down, but I actually reduced it to : ArrayList myArrayList= new ArrayList(); myArrayList.Add(new myClass(1, "First")); myArrayList.Add(new myClass(2, "Second")); myCombo.DataSource = myArrayList; myCombo.DisplayMember = "Name"; myCombo.ValueMember = "ID"; and it still takes seconds! Can anyone shed any light on this? thanks in advance, -- jo inferis Tag: Bastardized TabControl Tag: 88150

    - How to set the max row number in the datagrid. I use the datagrid to let the user edit the data in a table, say 6 row, 8 column, but I don't want the user hits enter at row 6 and the datagrid automatically append a new row on the datagrid (view). How can I set the max row limit? Also, I don't know if all of you have noticed, when you add just one row to a datatable and display it in the datagrid, you will see your data in the first row and a blank in the second row. Is there a way of just show one row of data but not additional blank? Thank you. lz Tag: Bastardized TabControl Tag: 88148

    - GDI resource leaks: Calling Dispose after ShowDialog I am fighting exhausted resources in a large application with many forms. It manifests itself by EVENTUALLY not being able to load an ImageList. In researching this I see advice in previous postings to call Dispose on a form when finished with the object, after a ShowDialog. It is suggested this is necessary to avoid GDI resource leaks. My question is, what about when you open the form non-modally with Show? Will the form do its own Dispose, or am I obligated to find a way for this to happen? If so, can someone suggest a strategy for managing this? - Lee Tag: Bastardized TabControl Tag: 88142

    - When opening a form: Failed to load ImageList When opening a non-modal dialog form which has an ImageList that I use for a Treeview, the program crashes. This does not occur consistently, but certainly often enough to be very annoying. It has happened two days in a row now for one user. The exception trace suggests to me that the .NET Framework is attempting to extract the bitmaps from the DLL resources, or such? It appears to be happening before any user code is being called. I have seen others report this problem, but never a resolution. It would seem to be a Framework bug to me. But maybe there is something I am doing?

    - AutoScale Doesn't Behave How I Expect/Hope I have just been playing with AutoScale and I am unhappy with the way it appears to work. I have a form created on a desktop m/c where the screen font is Normal (96 dpi). The form looks fine at design time and runtime. I run the application on my laptop, where the screen font is set to 120 dpi (125%), and the form does not look fine. The line height of a listbox on the form is too small, labels are truncated, and things generally look cramped. AutoScale is set to True. I notice that when I open the designer on the desktop, the AutoScaleBaseSize is (5, 13). When I open the designer on the laptop it is also (5,13). If I then change the AutoScale property in the properties window and look again at AutoScaleBaseSize, it has changed to (6,15). Now when I run the application on the laptop all is well. Well, almost. I should point out that user controls on the form still do not scale correctly, and since they do not have an AutoScale property, all I can think of doing is calling the Scale() method with a parameter of 1.25. The problem with this approach is that I would have to do this for every user control, and there are a lot of them. It doesn't seem right that I have to add special code to all my user controls to get them to scale properly. Furthermore, I haven't discovered (yet) how to determine the correct scale factor at runtime. I thought that the point of the AutoScale property was that a form would display correctly on m/cs with different display settings, without having to rebuild on that m/c. It doesn't look like that is what really happens. Have I missed out a step here? Does anyone know the correct procedure for making this work? TIA Charles Tag: Bastardized TabControl Tag: 88093

    - duplicate the FileWebRequest Class HI, newbie here.. What i want to do sounds very simple, but i am having a hard time getting the terms down so that i can even explain what i want to do. In any web browser where my client app is running, if there is a URL like "test://" or "dosomething://" that is clicked, i want my client app to catch that and do stuff. Please someone point me in the right direction. I have tried building an activex control but it dosnt support the DDE commands i want to use. I know that .Net dosnt either, but i am going around the whole DDE part in the long run. what i have is a phone applicaiton, i am integrating a web site with some of the parts of the phone app. when a phone number is displayed on my web app, it will have a hyperlink on like <'a href="call://201-555-1212">201-555-1212</a> This was my way of linking the two apps together (the call:// part) the phone app supports DDE, i have found a few free ocx's that will be my DDE client and server parts. But iam not worried about that for now. I just want to be able to pop up my client app when a link is clicked in IE and pass my app some variables. Thanks for any advise Tim Tag: Bastardized TabControl Tag: 88085

    - New Form Goes Behind Main Form when clicked. I have a main form and from it i am creating and showing a new form using the Show method. The form does not have an owner. It correctly appears on top of the main form but when i click it it goes behind the main form. If I then go bring the form to the front it is fine from that point forward. It is just the initial click after creation. I believe I have done what I describe here successfully in several apps before but I cannot figure out what is wrong here. Does anyone have any thoughts?

    - Problem Creating Handle I have a UserControl that contains a few ComboBoxes and TextBoxes. For most of the Controls/Forms that I drop this on, I'm not having any problems at all. One form, however, is giving me problems and it seems to be crashing in the CreateHandle method. I have put a breakpoint in the HandleCreated event of my UserControl, but it's never hitting it cuz it crashes before that. It's obviously having a problem creating the handle and I'm trying to figure out why. Does anybody know what event fires prior to the HandleCreated event? If I can set a breakpoint there maybe I can figure out what the problem is. TIA, ~~Bonnie Tag: Bastardized TabControl Tag: 88079

    - How Best to Move From Form to Form I've been a Web Developer for about 5 years, but am now being asked to write a Forms based application. My basic question is how best to move from form to form. I've read about MDI, ShowDialog, Form.Show(), and even just setting various forms from Visible = True to Visible = False. I guess, I'm a bit confused as to which would be the best implementation. Just to give a few details on my project... I will have a login screen, then once the user logs in I will have a main screen. Depending on the options selected on the main screen, the user will either be directed to a Delete Screen or a Copy Screen. The Delete Screen and the Copy screen really do nothing more than inform the user of actions taking place in a database. Basically just a logging/status screen. I know I'll need to implement threading for this, but I'm not sure how best to move from screen to screen. Thanks. Tag: Bastardized TabControl Tag: 88075

    - Some (not so?) general questions... Hi all. I'm primarly a C++ developer but I've been trying to complete development on a C# application with the following basic requirements: - The app runs in the background is initially hidden from the user, including the Windows Taskbar. - The app needs to receive a registered Windows message - The app needs to "register" its window handle with an unmanaged C++ dll so that a WM_USER message can be sent back to the C# app's WndProc - The app needs to display itself when receiving the WM_USER message, and hide itself after being acted upon by the user. I ran into some problems along the way and wondered if anyone could provide some feedback or comments. Especially since I told my project guy this should be trivial to do in C#, and now I'm wondering if I made the correct decision. I'm not looking good at this point. 1) In order to hide the app from the Taskbar, the main form's ShowInTaskbar property would be set to "false", easy right? That action, however, (using SPY++)removes the WS_APPLICATION style bit and prevents the application from receiving any registered Windows messages. 2) I initially call a C#-to-C++ wrapper function to give my ".Handle" to the unmanaged dll. This works for the first time, but when I set the main form's Visible property to false and minimize the form, "Handle" gets a new value. Is there some other "handle" I should be using? I work around this by "re-registering" with the unmanaged dll after minimizing but there have been a couple of occasions where a zero has been logged. Using FindWindow() in the unmanaged dll would be acceptable, is there a way to "register a unique window class"? The window titlebar includes message specific data so the title changes. 3) I have seen several instances where the main window was shown (Visible = true), but with no controls on it. Using SPY++, I see the main window listed with no child controls, and a "WindowsFormsParkingWindow" which contains all the children for this form. The data on the controls is correct, but it's as if they are just not on the right form. 4) I also intended for a Windows Service to start the application, which works, but the application does not survive a user logoff. We have C++/MFC applications which do a subclassing code trick to accomplish this but I've not found an equivalent for C# apps. http://support.microsoft.com/kb/q164166/ 5) I have the main form's TopMost property set to true, and after 2 hrs. of messing around, I discovered the tooltips are showing behind the form. This is the case for XP as well as Win2k. One unrelated thing: 1) Once in a while my VS.NET search function starts reporting something like "no files found to search in". Strangely enough, when I press CTRL+SCROLL LOCK it starts working again. Not a big deal once you know the trick. I apologize if I've missed this information but I looked in the groups and didn't see any real answers to these questions. I would greatly appreciate any input as to whether some of this behavior falls in the category of "that's just the way it is", or I'm not doing things correctly, or bugs to be fixed, or need to look at workarounds. I'm using VS.NET 2003 and .NET Framework v1.1 and the target OS is Win2k. Needless to say, I've been frustrated to this point in creating what I "thought" to be a pretty simple app. My fear (from a schedule standpoint) is that I have to start over in C++.

    - How to control the order in which individual child controls are rendered Hello All, I am creating an image browsing function within an application. As such, I created a Thumbpanel control (shown below) which displays a collection of thumbnails. Each thumbnail on that panel is also a custom control ( of a class called Thumbnail) placed at a calculated location on the Thumbpanel. It turns out to take 1+ seconds to construct and render each Thumbnail, so in turn it takes MANY seconds to render the whole panel. Therefore I need to force each Thumbnail to be rendered individually as they are constructed, so that the user will not be confused by the frozen screen awaiting the whole thing to render. I expected that the line: thumb.Refresh(); ... would force the thumb object (of type Thumbnail) to be rendered upon that call. But that didn't do the job. Can someone give my guidance on how to force rendering of the individual child controls (Thumbnails) in the order I specify? Thanks, -- Bruce ------------------------------------------- using System; using System.Collections; using System.ComponentModel; using System.Drawing; using System.Data; using System.Windows.Forms; namespace WTMWClient { /// <summary> /// Summary description for ThumbPanel. /// </summary> public class ThumbPanel : System.Windows.Forms.Control { Assets m_Assets; ArrayList m_Thumbnails; bool m_Scrollable = false; public delegate void ThumbPanelDoubleClickedHandler(object sender, ThumbnailDoubleClickedEventArgs e); public event ThumbPanelDoubleClickedHandler ThumbPanelDoubleClickedEvent; private System.ComponentModel.Container components = null; public ThumbPanel() { InitializeComponent(); m_Assets = new Assets(); // Simply a default value so it will not be null. m_Thumbnails = new ArrayList(); } protected override void Dispose( bool disposing ) { if( disposing ) { if( components != null ) components.Dispose(); } base.Dispose( disposing ); } ~ThumbPanel() { // ~base(); foreach (Thumbnail thumb in m_Thumbnails) { thumb.Dispose(); } } #region Component Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { // // ThumbPanel // this.Dock = System.Windows.Forms.DockStyle.Fill; } #endregion protected override void OnPaint(PaintEventArgs pe) { // TODO: Add custom paint code here // Calling the base class OnPaint base.OnPaint(pe); } protected override void OnResize(EventArgs e) { base.OnResize (e); PlaceThumbnails( false ); } /// <summary> /// Place each thumbnail in its proper position.

    - No clue why ShowDialog crashes.... This one has me completely baffled. I am calling ShowDialog on this form, and it is about the simplest form in any application. The form presents a multi-line text box for viewing, copying to clipboard, or printing. Maybe someone has ideas??? WoComMenuHandler is a context menu handler on the main form. WoComMenuHandler instances frmTextView, sets properties, and then calls frmTextView.ShowDialog and crashes as follows. There is no form load or activated event coded. WoComMenuHandler does this setup prior to ShowDialog sets properties, as follows: Dim frm As New frmTextEditor frm.Editable = True frm.DialogTitle = "WO " & WoNum.ToString & " Comments" frm.TextContent = wo.Comments If frm.ShowDialog(Me) = DialogResult.OK Then ... The properties (used above) in frmTextView are pretty straight forward. It doesn't crash setting these properties. It crashes on ShowDialog. Public Property Editable() As Boolean Get Return Not tbText.ReadOnly End Get Set(ByVal Value As Boolean) tbText.ReadOnly = Not Value If tbText.ReadOnly Then Me.btnOK.Text = "OK" Me.btnCancel.Visible = False Else Me.btnOK.Text = "SAVE" Me.btnCancel.Visible = True End If End Set End Property Public Property DialogTitle() As String Get Return Me.Text End Get Set(ByVal Value As String) Me.Text = Value End Set End Property Public Property TextContent() As String ' tbText is a multiline text box.

    - What direction to select? (Since this ng was flooded I repost this Q.) I declared a Form in Microsoft Visual Studio .NET 2003. On the form there are buttons and progression bars and three PictureBox in row, each showing a picture, later a movie. The three PictureBox should always occupy the available room when the form is resized (as much as reasonable) and if one of them is more interesting, I want to be able to size it larger covering the others. (A button press will size all of them back to the regular arrangement.) That is what I would like to do. (I could not find any examples yet.) Should I program windows instead of PictureBoxes or I should be able to use PictureBox? Would it be possible to display the short movies (20-40sec long each) in the PictureBox using a thread for each? Thank you for any guidance. Tag: Bastardized TabControl Tag: 88068

Greetings,

I was wondering if anyone knows if the following implementation of
TabControl exists out there.

TabControl would have 2 sets of tab pages. Both sets are aligned at the
top of TabControl, only the first set is aligned at the top-left corner
and the second - top-right.

Regards.
