    - Property grid navigation I have implimented a custom data grid and property gid on several of my forms. I find it really nice when updating multiple record. I select a dozen record or so and the property grid gives me the fields to change and the ones I change affect all. The problem is I have several customer complaining about the property grid navigation. I guess most people have gotten use to the tab key for field changing. Is there maybe some directions on property grid navigation I could refer to? I can only assume I am doing it wrong. Regards, John Tag: Invisble controls Tag: 75717

    - How to embed old C++ window into .NET form? I have a drawing application written in C++, and want to use it in a framework written in C#. Since the amount of C++ code is very large, it's unpractical to translate them to C#. So I want to use the window in C++ as a control in C#. It seems there are a lot of method to do this : 1. Rebuild the C++ code in C++/CLI, and try to call it in managed world. 2. Pass the HWND of a C# form to the C++ code, and attach it to a C++ Window and draw on it. 3. Pass the HWND of a C++ window to C# code, and attach it to a C# form and draw on it. 4. Pass the HDC of the C# form to the C++ code, and draw on that DC. 5. ... I think this is a common problem in porting old C++ code to C#, so there must be someone has already solved this problem. Could anyone give me some advice? Thanks! Tag: Invisble controls Tag: 75705

    - Screensaver with WinForms on multiple screens Hello, I have a question about how to display a single windows form on multiple monitors at the same time. I took the C# 2005 Express - demo project for the screen saver as an example - but in case you have multiple monitors this screen saver is only displayed at the main screen and not on the secondary display. Is there an easy way to display exactly the same output on both screens or to modify the form in a way that it spans over both (or even better: any) available screens?

    - Justifying Text in a RichText control I'm attempting to format rich text with C# by sending messages to the underlying richedit control. The text can be formatted by sending an EM_SETPARAFORMAT message. However, when I set the wAlignment to be PFA_JUSTIFY, it doesn't work. I know that this option only works with Rich Edit 2.0 or later version. Wouldn't VS .Net 2003 be using at least that version of the control (or newer)? Has anyone gotten this to work?

    - icons grouping with generic icon in XP toolbar I have my XP configured to group icons if there is more than 1 icon (window) associated with an application. each of my .NET forms has a custom icon for the application but when they are grouped on the XP icon they become a generic application icon (a white box with a blue strip on the top). if i click on this icon then a sub-menu opens up with each individual form *with* the custom icon correctly shown. how can i ensure then when XP groups icons that they retain the custom icon for my application ? -simon Tag: Invisble controls Tag: 75684

    - Netadvantage Ultracombo & date time problem Hi I have this application that I am fighting with for days now. Here is the whole project; www.infovis.biz/tasks.zip. Please run and press the new task button to see what I mean. Much of the code is either form taskvision or infragistics samples btw and requires netadvantage 2004 vol2. I have the following problems with this and would appreciate any help I can get; 1. When I click in the clients field, I then click on any other field the cursor is stuck in the client field requiring an entry to be typed or selected. How can I make it so I can leave this field blank if I want to? 2. When a value is typed in the subject, details etc. fields, the time part of 'Remind date' disappears. 3. In any event, the remind date & time are not being stored properly in the tbltasks table in the access database. Not sure where in the code these values are lost even though I can see them on the screen when saving the new task form. 4. When I type a value in any field apart from client field, a 0 appears in the client field if it is blank. How can I avoid that? Thanks Regards Tag: Invisble controls Tag: 75665

    - Process.Start problems I'm just starting to learn VB.Net (winforms) - having known classic vb for years... I was trying to build a 'dll compiler' just for grins, using the vbc.exe that resides in the DotNet Directory. I have a form that browses to that directory, and builds a string from it, adding "vbc.exe", along with the proper arguments, like this: vbcApp = txtDotNetDir.Text & "\vbc.exe" Process.Start(vbcApp & " /out:" & sFinal & " /t:library " & txtCBDir.Text) sFinal merely builds a string with a path and the name of the new dll to save - - It always stops on this line and says : An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.dll Additional information: The system cannot find the file specified I've double checked and each of the variables in the equation have valid paths/filenames and if I used it all manually at the command prompt, it would work just fine What am I doing wrong here?

    - performance problerm with custom control I have a custom control A, that has two text fields and a datagrid object. the datagrid is populated within the control, quering the information from the database at the time of construction. Now I have a Form, with a tabbed control, let's name it B. On the object B we need to display N instances of object A with all the data filled. But for some reason, any time N gets larger than 10 the program slows significantly and if we need to add 30 or more instances of A the program gets a timeout exception. Any ideas?

    - Icon in Task Bar Hi, I have a VB.Net winforms program that monitors some report folder. All works well in that respect. I have the program start 'Minimized' and I also have the program automatically start when the system starts. However, the program sits Minimized as a big block in the Task Bar (Bar at bottom with the 'Start' button). What i'd really like is to have it be displayed as just an Icon with the collection of icons over on the right in the task bar near the clock. Is there sosme simple way to do that in Visual Studio so instead of just starting minimized, it just starts as an Icon? Thanks, -- John Tag: Invisble controls Tag: 75632

    - Sorting TreeView Hello, Standard Tree.Sorted property doesn't sort nodes like I want to. It just place them in a specific place while adding new node. This is not suitable for me, because during insertion I don't know node's name so it is placed in the end of all nodes. To make things clear I will cover some source code. Sorting works fine when I do like this: TreeNode newNode = TreeNode("Title"); Tree.Nodes.Add (newNode); This is my situation. As you see, when I add new node, I don't know its name so the sorting doesn't work. TreeNode newNode = TreeNode(); Tree.Nodes.Add (newNode); newNode.Text = "Title"; I need to be my tree sorted at any moment. Even when I change any node's name - it's place in the tree should be changed. What would you suggest for me? Is there any standard solutions or I should write my own sorting procedure? Maybe you could give me already written treeview sorting procedure? Thank you for any help. Vycka P.S. Visual Studio .Net C# P.S.S.

Whenever the required job is done in that background-running-thread, I would like to Enable and Start the Timer to do the related job from the background-running-thread. It is written in MSDN Library that "It requires that the user code have a UI message pump available and always operate from the same thread, or marshal the call onto another thread."

I finally noticed that when this happens there's an item in the task list that says : "Duplicate declaration of member 'Font'", though the build is successful. The app runs fine (all controls in their proper place) and the .cs file is fine. It's just that the designer goes a little crazy. I've found several posts about this (mostly the same message, but sometimes with member 'Location' or 'Size'), but most people think it was just a problem with an early version of Visual Studio 2003. I've got the June 2004 version and don't have a clue what I can do to solve this. I'd appreciate any help! Especially if someone from MS could look up the error message. I tried msdn, but don't find it. To attempt to recreate copy several of the same custom control onto a form. I can usually make the bug occur when I copy/paste 12-15 instances of the control. Please help! thanks, Deanna Tag: Invisble controls Tag: 75587

    - Button Properties Hi, I was wondering if the "default" property of a button has been changed to something else or if it has even been included in the .Net classes for C# as it was in VB 6?? Regards Darryn Tag: Invisble controls Tag: 75583

    - How do you use one dataset in multiple forms? I have an application with a form that has bound controls to dataset.tables. I have an Add button that brings up a modal form and I'd like to work with the same instance of the dataset to insert new records and use combo boxes that are populated from that dataset. The dataset gets filled when the parent form loads. When I load the modal form I've tried accessing the dataset in the parent form but I'm not having any luck. Any help appreciated.

    - Exception Handling and Call stack unwinding Hi all, Am experiencing a problem with the Application.ThreadException event which the documentation indicates is fired in the event of an unhandled exception. It seems to be ignoring the exception handling further down the call stack - in fact it never seems to unwind the call stack at all. I am not sure if this is me doing something wrong or will that event fire in the event of any exception being raised that is not caught within the same routine or possibly even the calling routine? So the question is does the event fire before or after the unwinding of the call stack and if its before, does it stop the callstack unwinding? Regards, Peter Cook Tag: Invisble controls Tag: 75574

    - DataColumn Expression Is there a way to insert a blank line (\n) into a DataColumn expression? i.e. Dim dc as new DataColumn("test1", Type.GetType("System.String"), "Address1 + '\n' + Address2")) I can't seem to get .NET to recognize the escapt character Thx, Joel Tag: Invisble controls Tag: 75572

    - Printing and exporting a Form or Control which spans multiple screens I want to print a Form or Control which is scrollable and only part of it is visible on the screen at any given moment. (the form may be an image, a text page and an IE browser page) Another task that I want to achieve is to save that same Form in a file (image file if it is an image, text file if it is a text) The problem is that all I know about it is that it is a Form. Nothing specific about the content. How can I achieve this? Tag: Invisble controls Tag: 75567

Please, Help!!!

When a control is visible=false, or is used in a tabpage that is not the
current one, de value is not updated in the control.

For examples, use a tabControl, place two tabpages, in the tab 2 place a
textbox control, in the tab 1 place a button that set a text to de textbox in
the tab 2, when running, click the button and go to the next tab, and you
will see no value in de textbox.
