    - Japanese Win98SE + winform = Red X I have a WinForm that works wonderfully in Western versions of Windows, but is having trouble with Win98SE Japanese, and I'm loading other Far East character versions to see if it is consistent. Controls appear with a red X and an exception is thrown with the English text below. Any suggestions?

    - winforms data exchange style question I'm making the jump from MFC to C# and I have a style question. I have a form which modifies an object. At some point a change is made to the object which requires refreshing all the fields of the form. In MFC you would put this code in DoDataExchange(). You invoke this code by calling UpdateData(false). What is the equivalent convention in winforms? Regards, Bob Rundle Tag: WinForm control will not display with TreeView control Tag: 74718

    - Hey, MS guys, advice is need for HelpProvider I want to display unicode characters in a HelpProvider's HelpString. I'm eagerly anticipating someone's oppinion about if this is possible, and if it is, how can i do it, because the cyrrilic characters that i enter as a value for the HelpString property get messed up when they are displayed. However, there's no such problem with tooltips, even though they seem to be using a similar mechanism. I had the idea of deriving from HelpProvider and overriding some of the functionality but as long as HelpProvider is from the Windows.Forms namespace it's source is not included in the SSCLI implementation of the framework, so i cannot taste it's inner workings. And guys, please skip answers such as "Don't multipost". Yes, i have posted about this before but as i'm posting again as long as no one paid attention to my previous post i go shooting the same question again becuase someone definetly has to know if there is a reasonable workaround for my problem or i have to manually implement some popping up rectangles with helpstrings. Thanks for the attention Tag: WinForm control will not display with TreeView control Tag: 74707

    - Making a form a child of a control In Delphi it's possible to make a form appear inside a panel control as a child subform by setting the form's Parent property to the instance of the control. When I try to do the same in .NET I get the error "Cannot make a top-level control a child of another control". It would really be a huge disappointment to find out that Windows Forms doesn't allow nesting of forms inside panel controls, so I hope I'm just not doing it right. Any suggestions?

    - ComboBox.SelectedText always returning empty string Hi all, I know I must be missing something very simple here, but this little problem is baffling me. If you have a combobox called cmbMyCombo and add a bunch of strings to it, say, "Apple", "Pear" and "Orange", and then call the cmbMyCombo.SelectedIndex it will tell you the index of the item that was selected. However, you would think that if you called cmbMyCombo.SelectedText it would give you the TEXT of whatever was selected (i.e. Apple, Pear etc), but all it does is return an empty string. Does anyone know why this is? Dano Tag: WinForm control will not display with TreeView control Tag: 74659

    - Exception with AsyncCallBack + Control.Invoke I posted it in the wrong newsgroup. So I have to repost it again. Sorry. I used Application.ThreadException event to handle all unhandled exceptions in WinForm application. However, when I start converting my application into asynchronous operation, I have faced with some problems. I used AsyncCallBack to do something when the operation finishes. However, as you might know, AsyncCallBack delegate will be called in a different thread from the activated thread (which is likely to be the thread that run the asynchronous operation). In certain cases, this delegate might throw an exception and I WOULD LIKE to have the Application.ThreadException to handle this exception. But I cannot do that since the current thread is not UI thread. So, the exception will just disappear. I also thought of a silly idea by calling Control.Invoke(ThrowAnExceptionForMe) but inside Control.Invoke, there is a try-catch block which will throw an exception back to the calling thread (which is not a UI thread). It would be nice if I can find a workaround for this without changing the way I handled the exception (I mean still depending on Application.ThreadException). Any suggestion?

A config file is used and the web.config file has been modified to permit its download Between tests I clear the download cache using gacutil and the Internet Cache The webshare has been configured not to execute scripts Any pointers on this would be greatly appreciated.

    - is Disposed required for shared form ?? Hi, I have a Windows App which uses a custom form to display messages. This form is based on the singleton pattern so that the user does not need to explicitly create an object of this form. After the Showdialog() method on this form, do i need to dispose this form explicitly. i distinctly remember one article saying that all Modal forms needs to be disposed explicitly. This is the code snippet i am using: Public Class myMessageForm Private Sub New() 'new instance not possible End Sub private Shared frmMsg as MyMessageForm = Nothing Public Shared Function Display(ByVal text as String) as DialogResult If frmMsg is nothing then frmMsg = New MyMessageForm End If 'Set some properties Return frmMsg.ShowDialog() End Function Calling Code: If txtCustId.text.Length = 0 Then MyMessageForm.Display("Invalid Customer Id") End If Any help would be appreciated.

    - Problem with the Windows Forms Designer... I have a custom control called, lets say, SportBillyComboBox, which inherits from ComboBox. When I add my control from the toolbox, I get an error (System.NullReferenceException : Object not set to an instance of an object) on my form replacing the control, but my newly added SportBillyComboBox is there (even if "you can't see it" - under the Exception) and seems to work fine in compilation and in runtime. But when I next use the Windows Forms Designer to change or add something, it automatically adds those lines in the designer : this.SportBillyComboBox1.Items.AddRange(new object[] { ((object)(resources.GetObject("SportBillyComboBox1.Items"))), ((object)(resources.GetObject("SportBillyComboBox1.Items1"))), ((object)(resources.GetObject("SportBillyComboBox1.Items2"))), ((object)(resources.GetObject("SportBillyComboBox1.Items3")))}); Even if I never asked in the Designer to add some items in the collection, it magically appears in my InitializeComponent Code - TADAM! But worse of all, it doesn't add the necessary entries into my Form1.resx resources file so the code crashes on the newly automatically magically added line. Sure, I can always erase those lines, but every time I change something in my form, it add those lines again and again and again... Anyone having a fix for this one? Even my first problem (when I add the control to my form... the little "System.NullReferenceException" error) is disturbing! Do you have any clue?

When trying to get all the IE-windowd with the "For Each p In Process.GetProcessesByName("IEXPLORE")"-function, I only get 1 process returned, which has as "p.MainWindowTitle" the MainWindowTitle of one of the open IE-windows.

    - Bring another Window to Front Hi, My application has some interaction with an other application. I sometimes need to put the other application to the front. The problem is that I'm not able to get a nice solution to work in every case. I tryed two ways: one way it disn't maximazi the Windowd when it was Minimized, in the other way it resized the application when it was maximzed. First I take a Handle to the other Window with the "Process.GetProcessesByName("EXTRA")" and with the "Dim handle As IntPtr = Process.MainWindowHandle" First 'solution': SetForegroundWindow(handle) This gives me the problem with Mimized Window that gets the focus, but Second 'solution': ShowWindow(handle, SW_RESTORE) 'SW_RESTORE = 9 SetForegroundWindow(handle) This gives me the problem with the Maximized Window that is suddenly resized. What I actually need is a solution that works always: When the Windowd is Maximized, it has to keep Maximized. When it is Resized it has to stay Resized. When it is Minimized it should be Restored (to the last Status: Maxmimized or Resized). I found some stuff about the IsIconic-API, but it didn't seem to work. Does anybody knows a solution for my problem? I'm really stuck with it :-/ thanks a lot in advance, Pieter Tag: WinForm control will not display with TreeView control Tag: 74634

    - Suppress ActiveX Control Warning in web browser control I'm writing a windows app in c# that can display offline html forms. The app uses the Microsoft Web Browser COM control. The offline forms our generated by another application. The offline html forms contain script code that saves the users inputs in an XML file on the client machine. This script code uses the wsh FileSystemObject and causes the web browser control to issue the warning "An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction? Yes / No" Is it possible for my windows app to intercept this warning before it is displayed and return a positive response (i.e. the same as the user clicking 'Yes') ? I know the warning can be suppressed by setting the silent property to true (axWebBrowser1.Silent= true;) but this defaults the answer to false (i.e. the same as the user clicking no). Any suggestions would be appreciated. Thanks Andrew. Tag: WinForm control will not display with TreeView control Tag: 74628

Including Editors and Converters. Now I have a really special question.

By using a Editor(the same for all my properties) I have been able to go through...Altmost. I can now display the color I want for a gridItem (on the 'value' part) but since I just redraw a rectangle and fill it with the appropriate color I still have a white back color for the text representation which makes my propertygrid simply ugly. Therefore, Does anybody know how to fully customize the back color of a gridItem within the propertygrid ?

    - Question about Image Hi all, My problem is, I have created a form with a background Image assigned to it. On top of it, I have an instance which is a subclass of PictureBox. I overrided the PictureBox OnMouseMove method so that it moves along with the mouse movement. Though there is no problem when moving the PictureBox, as the PictureBox moves, the form's background Image doesn't update the area under the PictureBox, there are still some images remain on the screen after the PictureBox change its location. Can anyone tell me how to solve this problem? Thanks in advance. Tony Tag: WinForm control will not display with TreeView control Tag: 74574

    - Snappy Rendering of Controls I have a situation where I'm hosting a number of complex controls within a form, but only showing one at a time. When the user clicks on a navigation button one or other of the controls is displayed. My problem is that, as the control is revealed (it's Visible property is set to True), it flashes quickly as parts of it are rendered (that is, I can see squares of white flashing until their BG colors a drawn etc). What's the correct appropach to take when revealaing a control to avoid this kind of thing? What I'd like is for it to just snap up in one go. Is there anything I can do??? Thank you! === Phil (Auckland | Aotearoa) Tag: WinForm control will not display with TreeView control Tag: 74568

    - Getting the popups above the running form. Hi, I have a form that scans my entire C: drive for some files. In order to show the status of scanning I use Application.DoEvents to show a label with the folder being scanned. All this runs fine. But whenever there is a popup from another application, that Popup comes below my running form. How can I make these popups get displayed above my form so that the User can see it as soon as it is popping up. TIA. Tag: WinForm control will not display with TreeView control Tag: 74562

I am developing a WinForm control that is embedded in an HTML page as a smart client. If I build the control without the TreeView control - it embeds and displays just fine. If I build the control with the TreeView control - it will not embed/display. Any help would be appreciated. Thanks!
