    - What classes does CF.NET support? Hi, Last night I was trying to append to a text file. After popping the buzzwords into google I was directed to the MSDN site and I happily coded away using an example as reference with File.Append. It turns out File.Append is part of the full .NET and not the CF.NET subset. How can I restrict my searches for classes within CF.NET? Is there no support in CF.NET for Perl's most excellant line-oriented reading/writing, or is this the preferred way to create/append to a file: private void saveDetails(string client) { Stream s; try { s = new FileStream(FILE_NAME, FileMode.Append); } catch (Exception e) { MessageBox.Show("cannot open file " + FILE_NAME + ": " + e.ToString()); return; } for (int i = 0; i < client.Length; i++) { byte b; b = (byte) client[i]; s.WriteByte(b); } s.Close(); lblSaveError.Text = "record saved"; } Thanks, Joe.

    - Closing DataReader - an expensive operation? I did some rather primitive instrumentation to see what was taking the longest in some SQL Server CE code. The culprit was this line: dtr.Close(); Any idea why it would take 7-8 seconds to close a DataReader? Lots of data has been read from the datareader; I thought this would be the expensive part. And any way to avoid the hit? I could neglect to close the datareader, but I'd guess that is a bad idea. Nathan Tag: ArgumentException when adding to this.Controls Tag: 56859

    - Exception when set combobox default value I have a combobox which binds to a dataset with id and description. The combobox populate all items and I can get the selectedValue. But I cannot set the selected value. I always got exception with no further error info. I read some posts on this forum talked about u have to set selectedindex twice to let it work.

    - Proxy Authentication Required I am having a problem with getting a reponse from an HttpWebRequest from the emulator. I keep getting an error: 'Proxy Authentication Required'. I have an ISA Proxy on the network. This problem only occurs with the Pocket PC 2003 Emulator and the Windoes CE.NET Emulator. It works ok on the Pocket PC 2002 emulator and on the actual devices. I can use the IE in the emulator to connect the web site if I configure IE to use the proxy server and give credentials. I tried setting the proxy in code and suppling credentials, but this doesn't work and causes problems. Why is special code to handle proxy not necessary for 2002 emulator or actual devices and how can I get the 2003 Emulator and CE.NET emulator to work?

    - Detecting the Microsoft .NET CF As MSDN says to detect .net cf I must enum values from "HKLM\SOFTWARE\Microsoft\.NETCompactFramework" (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/netcfdepl.asp). What if there are more then one value? How can I detect which one will be used by application. Specifically: I have hp iPAQ with WM 2003 SE and preinstalled .nect cf on it (and seemes like it cannot be removed since it is not displayed in the Remove Programs applet). But I can install .NET CF to the device without any special messages from the .cab file and it will apear in Remove Programs applet. This adds new value to the "HKLM\SOFTWARE\Microsoft\.NETCompactFramework" registry key. So how can I be sure which one of this installations will be used by application?

    - multiple panels, Send to Back Hi, I am developing a simple CF.NET as a learning exercise. I want to have multiple pages for a user to input basic information, then to save to disk for later processing. Each page will have back and forward buttons, the final page will clear the fields on preceeding pages and put the user back to the first page for a new user. I've tried using multiple forms, since then I've found panels which I'm assuming is the more efficient or better design? How can I be sure that a component such as a Label or a Textbox is attached onto a Panel? I tried to attach a component to my 3rd panel, but when I run the application a component is on the wrong page. I have been right-clicking on the panel and then 'Send to Back' to view other Panels. Since adding a 3rd and 4th Panel, the 'next' button (one on each panel) has stopped navigating to the my next intended panel, instead on the 2nd panel it now jumps to the 4th. I also cannot view one of my earlier panels, and don't know how to Bring to Front as I cannot see it to right click on it. All these problems seem to have stemmed from Send to Back and Bring to Front. Any advice would be greatly appreciated. TIA. Regards, Joe.

    - Fragmentation of FAT filesystem on flash disks. I'm have an application that has been running on Intermec 720 terminals with Pocket PC 2000 for 3-4 years now. I store the database and the datafiles that this application generates on a flash disk card. My problem is that this application is now much slower than it was before. We have traced this problem to a very fragmented filesystem. When we defragment the flash disk with StorageTools from SoftWinter the application get's it's speed back. We could of course buy this program for all teriminals we have out in the field. (I think it's 400-500 spread all over Norway). But it's not a very realistic to think that the users of our program will be able to run it them self. So the best solution is to let our program do it.

    - DataGrid ArgumentOutofRange Exception I have a DataGrid in my application that is bound to a custom collection of business objects. The collection inherits from CollectionBase so is bindable. My problem occurs when I remove an item from the collection. After the removal, any time I click on the grid, I get an un-catchable ArgumentOutofRange exception. I tried a few workarounds: 1. Before removing an item from the collection, I set the DataSource of the grid = Nothing. Then I removed the item, set the DataSource back to the collection, and called Refresh. This caused the grid to re-display with the removed item gone, but as soon as I clicked on the grid, I got the exception. 2. I added an IBindingList implementation to my collection and set SupportsChangeNotification to True. I raised the ListChanged event in the Add and RemoveAt methods of the collection. This caused the grid to update correctly without resetting the DataSource, but I still got the exception when clicking on the grid. By the way, I get the exception whether or not there are any event handlers attached to grid. Any advice would be appreciated.

    - DirectX vs GAPI I am beginning work on a .NET compact framework application that will target Windows Mobile 5.0 and above. The application is 2D graphics intensive and GDI is not really fast enough. We were thinking about using GAPI or DirectX, but that led to other questions. 1) Is GAPI dead now that DirectX is going to be released with Windows Mobile? What I am more worried about is that GAPI will not be hardware accelerated in future products, because all they will worry about is DirectX? 2) Printing - I know the compact platform does not really support printing, but for this project we are required to talk to printers via wirelessly. Yao talks about this in his book, but is there anyway of drawing to a printer dc using GAPI and DirectX?

    - Help on debugging application after release Hi all, We have written an application for Windows CE .NET whose data will be very important and cannot be lost. During on-the-road testing, we had a couple of unhandled exceptions occur, and the exception did not happen every time the same operation was carried out, so it is difficult to know why it happened, especially as it was a user relaying the information through someone else to me, and one cannot be sure of the reliability of the information. The problem is that if an unhandheld exception occurs, there is no information about the exception shown. I was thinking of using log files to log exception error messages and types (even though the line number is not accessible in the Compact Framework), whenever an exception occurs. I could enclose try blocks around all SQL operations, as these seem to be a likely place for exceptions to occur. In this case I could also write the SQL statement to the log file, which would do a good job of identifying the possible location of the error. The problem is how to catch the other exceptions. In Visual Basic (which I used to program in) in every function one could put a "On Error Goto ErrHandler" statement at the top, and then at the end put error handling code where code for writing the error details to a log could be put. I suppose that to at least find the function in which the error occurred, I could in every function enclose the code in one big try block, and put the catch at the end, but would this in any way affect performance? Also I feel that this is not good programming style, is this correct? I have not been programming in C# long. Are these the only options open to me? What is the best way to use try blocks to catch exceptions when you want to be able to catch all exceptions and find out where they occurred? I understand that there may be a bug in the code that will only manifest itself when in the complex working environment, but I would feel better about it if I could be relatively sure that the first time an exception occurrs, that I could be reasonably sure about having enough information to fix it. It worries me that we might be in the dark and helpless to effectively fix these problems. Is anyone else in this situation; does anyone know the best way to approach this? I would sincerely appreciate your help. Best regards, Jonathan Dudley Tag: ArgumentException when adding to this.Controls Tag: 56698

Can the combo beacome larger automatically or give a tooltip? Tag: ArgumentException when adding to this.Controls Tag: 56693

I'm trying to add an object to this.Controls, using this.Controls.Add()
on a Panel object.

When I'm trying to do so, an ArgumentException is thrown. According to
MSDN, an ArgumentException is thrown by ControlCollection.Add() if the
child parameter does not specifiy a control.

If I catch the exception, and read out the Type of the object I added
(using GetType() ), I'm getting System.Windows.Forms.PictureBox (as
expected).

What am I missing here?
