    - 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: CheckBoxes in TreeView Tag: 74659

    - I have a master form, but... Hi all, I am now using a master form to derived my windows forms from. The problem is - I dont know how! I have a master form with a menu control across the top, I have then 3 others forms that I want to inherit the master form, I have added inherit master form etc at the top - in the design view of VS they appear fine. When it run the application I get a blank (master form) with the menu and nowt else... I basically want one of the other forms to load/appear/be visible etc, how does one call it in - lets say from the click on an item on my menu..? Any help appreciated - this has been a bit of a show stopper :( Regards Rob Tag: CheckBoxes in TreeView Tag: 74652

    - DateTime values in DataGrid I am populating a DataSet using SqlAdapter and then displaying it in a DataGrid. Some of the values in the DataSet are DateTime. It seems by default they are displaying as dd/mm/yyyy and I want to also display the time. I have played around with the DataGridTableStyle and the DataGridTextBoxColumn but nothing seems to take affect. Is there a good resource that outlines how to use these classes or is their an easier way to go about things? -- Dan S Tag: CheckBoxes in TreeView Tag: 74651

    - 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?

    - How many touches does no touch deployment take? ERROR: Not Found Now I guess I am missing something very basic here, but it has now taken nearly a full week to get my app launched from a browser URL - and still I haven't succeeded. The error I am getting now when I launch the exe as a URL is 404: Not Found. But what isn't found???? 'ntmizar': Loaded 'dw9ryd7d', No symbols loaded. 'ntmizar': Loaded '2hulxqpj', No symbols loaded.

BACKGROUND I can launch the app by URL from the development machine but not from several other PCs which all have the .NET framwork v1.1 installed. The windows forms application (exe) and support dlls have strong names and are all in the same directory on the webserver. I have configured security to Fully Trust everything from this URL. The app has been built in debug and release configurations and all files in the bin directory copied to the webserver. 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?

    - get Handle to an Application/Window, not a Process Hi, I need to do osme handlings with an Internet Explorer Window. The problem is: when the user has one ore more Internet Explorers opened, this is (sometimes) indicated in the Task Manager as one process and not 2 or more. 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. Like that I'm not able to work with that IE-window I need. Does anybody how to get arroudn this problem? Is there a way to go directly by the Windows/Applications and not the Processes?

    - 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: CheckBoxes in TreeView 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: CheckBoxes in TreeView Tag: 74628

    - No Cursor in pop-up window I am creating an MDIForm application in CSharp.Net. When I open a new form the focus does not appear to the be in the first field.

    - PropertyGrid:customize the backColor of the 'value' part of a grid Hi, Thanks to many codes over the web(specially this one www.codeproject.com/cs/miscctrl/custompropertygrid.asp) I've been able to use the .net propertyGrid the way I wanted. 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.

    - Stacked panel controls I'm trying to do something simple and can't seem to get my way with the forms designer. My form is divided in two: left side a tree view control, right side a panel with splitter control inbetween. So far so good. Now I want to stack panel controls on the right side. The idea is that as I click on tree nodes on the left side, a particular panel is made visible. So all the panels have to have the form as the parent. Then I programatically set visibility of the panels in the select handler for the tree. I can get this working if I massage the code that the forms designer generates. However I can't seem to drop panels into the form such that all the panels are children of the form. Furthermore my hand massaged code is obliterated the next time I fool with the form.

    - Help me remember a vsnet framework ad? Access dev testimonial Within the last month or so, in a mag or on the net, I saw an add for what I think was a vbnet ide framework or addin where there was a testimonial from a user that said they were a long time MS Access developer and that they liked whatever framework it was. I have looked "everywhere" and can't find it again. Does this ring a bell with anyone? It could have been in an older mag, but I don't think so. Tag: CheckBoxes in TreeView Tag: 74550

    - Changing focus leads to increase in memory!!! I have observed that when I change the focus (Not minimize) from my .Net app to some other app and bring the focus back, the memory used and VM size increases slightly. I have observed the same behavior for some other .Net apps also. Why is this happening? Is there a memory leak somewhere in my app or is it something to do with framework? Is framework painting my GUI again or something like that? Tag: CheckBoxes in TreeView Tag: 74547

    - MDI Child / Dispose / GC / = null I have a mdi child in my app with a business object member variable. it seems that this business object exists until the application is ended, no matter i call GC.Collect(). (i did some reference counting + a weakreference static list in the business object to find out what is going on) If i put 'businessObject = null' in the dispose mehtod of the child form, the business object is destroyed as i want from the garbage collector but it can't be for real that i set any object to null in the dispose mehtod?

    - How to determine the width of a single character in TextBox? I am writing a Windows Forms application using Visual Studio.NET in C#. I am creating a control derived from TextBox that will need to invoke a block cursor (caret) during certain edit modes. The derived control is intended to contain numeric values; integers and floating point. I understand how to create and position a caret using CreateCaret() and SetCaretPos(), available in user32.dll. The control's font may vary from instance to instance so I want to make the caret have the correct width and height. I can get the height of the font by using either the TextBox.FontHeight property or the Font.Height property. However, I have not found a way to get the width of a character so that I can size the caret width appropriately. Since the control can contain a decimal point and a minus sign I would really like to determine the width of any individual character so that the caret does not overlap adjacent characters. How can I determine the width of a character at a given position in a TextBox? Thanks, Dave Tag: CheckBoxes in TreeView Tag: 74535

    - richtext to XML Hi all, I'm trying to build a little app. that allows users to paste copied text into a rich text box, then hit a button and out spits XML into another textbox. I'm mainly concerned with capturing font attributes like italic, bold, etc... from the rich text so I can output text with the appropriate XML nodes indicating the proper markup around the text in the second text box. I've done a few searches looking for code snippets and such but so far I'm not coming up with much. If anyone here could point me in the right direction to some resources on how to parse rich text I would be very appreciative. Thank you for you time. Tag: CheckBoxes in TreeView Tag: 74528

    - Wiring up events in a less-messy way I'm frustrated with the way I've been handling events previously inside WinForms apps. It always seems that I end up with the effect I call "AddHandler Hell". I would like to do things a little differently and try to apply a little more object-orientation to events; for a low-level example, I would like to have my main MDI form and some child forms enable and disable some buttons and controls based on the user's login status (logged in or logged out). What's the most efficient way to almost define an event globally, so that when my "UserAuthentication" class raises an event, say, "LoginStateChanged", that the main form and child forms can respond to it without having to individually wire up and keep track of each window? It almost seems like I should be able to define a central shared/static class that holds most application-wide events (i.e. an AppEvents class), and allow my UserAuthentication class to raise AppEvents's "LoginStateChanged" event. Can someone shed some light on this for me? Brandon Tag: CheckBoxes in TreeView Tag: 74527

    - Child Menus, what would the best way to do this Hopefully this will come out right but this is what I'd like Main Fruit ======= Squares |___by color |___Red |___Yellow |___by size |__Large |__Medium |__Small Circles Triangles Is there a way to have the sub menus attached to Circles and Triangles without manually adding each one in the code? Yes that would be merging right? ok now how can I determine who called Large Yellow or Small Red, do I have to do something like sender->parent->parent->text ?

I want to implement checkboxes in all child in a treeview EXCEPT all top
most root nodes.

TreeView control's CheckBoxes property implement this functionality to all
nodes.
So is there some way to implement CheckBox to some specific node?

Thanks
