    - datagrid doesn't reflect changes in data (unless datatable) Hi! After a tip from Alex Feinman I manage to databind a datagrid to an arraylist (thanks!). But the datagrid doesn't reflect changes in the arraylist, unless I do the following dg.DataSource = null; dg.DataSource = myArrayList; ... which doesn't seem very effective. Is there a better way?

    - Uniqe identification of devices I have a C# application that runs on about 500 Pocket PC's (Intermec), and when I talk to these Pocket PC's I need to know which Pocket PC I'm talking to. Is there any way I can do this. Is there a unique identification in the OS ? I think I have read something about this somewhere but I can't find it.

    - Bug in DateTime I have written a inventory application in C# that was used in 21 stores this newyear. The data from this application is written to XML. On each item that is scanned (we use Intermec Pocket PC's) we write the datetime when the item was scanned to the XML (on each record). I got about 60000 records form these stores to process. That was no problem. But on a few of these records I got the year 2204 in the scannedtime element not 2004. These records could come among records that where ok, and they were few. Is there a known bug in the DateTime class? Thore Berntsen VBD Tag: switch a member from const to variable and viceversa Tag: 17848

    - GetDeviceID broken - please help - I'll post working code Hi, As I mentioned in an earlier post, Microsoft's GetDeviceID is broken on some PDAs (MS URL appears at the end of this post) - this is not a pre-2002 issue since it has occurred on a Mobile 2003. Unfortunately, it works just fine on my PDA, so I'd like y'all to test something for me. Once I have it working, I'll post the working GetUUID method. Please download http://www.hiltonswebsite.com/GetUUID.zip and run its EXE on your PDA - this is a simple C# app. If you are weary of EXEs (which you should be), please download the code http://www.hiltonswebsite.com/MainForm.cs, compile, and run that. Those who do this - thank you! Code you please reply to this post (or email me at hiltongoldstein@mindspring.bla (replace 'bla' with 'com' - I get about 100 spam emails per day anyway). I need these 4 items: 1. The UUID reported via the System utility 2. The ID Size reported by this EXE (should be 6, but I've seen 8) 3. The UUID0 reported by this EXE 4. The UUID1 reported by this EXE BTW: If you are concerned about giving away your UUID for whatever reason, just don't report then first few characters; i.e. leave off the first XXXX-XXXX-XXXX. I would REALLY appreciate your help with this, and hopefully I can post a working GetUUID() method soon. Thank you!

    - vb.net multithreading problem Hi, I'm trying to program a multithreaded application - it currently works, but I have two problems. I'm relatively new to VB.NET (vb6 and C were my things) so I'm kind of lost here. The code is based on the countdown / controlinvoker quickstart at GotDotNet.com. The problems are: (1) There's a memory leak somewhere. I don't know where, but it's probably something stupid I've done in the code below. (2) How do I set it up to exit gracefully (i.e. where in the application should I set threadsRunning = FALSE); at the moment even when in debug mode it crashes when stopping - I assume because I haven't sewn things up properly. The basics of the thread architecture are below. I've added a second thread to the quickstart code, and I've added a second ControlInvoker instance. With regard to the two threads, one updates the screen and the other communicates with a data comms interface, and passes some of this data to the serial port. The communications routine should take priority over the screen updating. Can anyone cast an expert eye over it and tell me where I'm being thick? I'd be very grateful.

    - Proper way to install CE 4.2 emulator I installed to C:\Program Files\Microsoft Visual Studio .NET 2003\CompactFrameworkSDK\ConnectionManager\Bin, since 'emulator.exe' was in that directory. The install program's default was in some samples directory. In VS when I run a project on the emulator, the splash screen still comes up as CE 4.1 emulator. It appears the new emulator.exe and pbemulator.exe files were put on to C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\bin. 1. What is the proper dir to tell setup.exe to install to? 2. Should a new device appear in the list of devices in Visual Studio 3.

    - bypass downloading CF to CE.NET device We have an OEM CE device with CF built into the image. We also use remote debugging. I have noticed the CF is always downloaded to the device when the debugger is first launched even if it is already resident in the image. Is there a way to override this? I have an image with CF SP2 built with Platform Builder embedded. When debugger is launched the original CF 1.0 RTM (from VS) is loaded (not what I want). I know I could copy the sp2 redistributals to the VS directory to allow the sp2 file to download, but from what I have read this is not recommeded.

    - Control.MousePosition & ContextMenu Problem Hello All, I have looked back through the postings in this group and there seems to be a recognised problem with getting the MousePosition for a control when a ContextMenu is assigned to that control. It seems that a tap 'n hold event does not update the MousePosition. There doesn't seem to be a problem when using the emulator only when running code on an actual device. The following code shows this problem. Private Sub ctxList_Popup(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ctxList.Popup Dim hti As System.Windows.Forms.DataGrid.HitTestInfo mousePoint = Me.grdList.PointToClient(Control.MousePosition) hti = grdList.HitTest(mousePoint.X, mousePoint.Y) If hti.Type = DataGrid.HitTestType.ColumnHeader Then MsgBox("Header") Else MsgBox("Not Header") End If End Sub When you click on a column header you will occasionally get the correct message. I have not been able to find a resolution to this problem - Has any one else? This seems to me to be a major Bug, but maybe that's because I need the functionality.

Hi I did not see a lot of smartphones devices on the market , the one i saw are rather unhandy. and large (more CPU , more memory and as result more power consumption and reduced operating time between re-charges) I have seen other phones with operating systems that have a smaller footprint (Symbian OS on ericsson P900 and P800 ) (and where is the pen touchscreen on smartphone ?) Its seems that not always the big names steal the show. Am i the only one with this viewpoint or is this fact ?

    - Re: HELP!! ListBox_SelectedIndexChanged Ginny, I've been playing around with events for a bit and ended up using the SelectedValueChanged of the ListBox control. Basically I'm not using databinding anymore to change the customerID of a label but rather the .Text propery. I do however still have a problem with refreshing my DataGrid. I've pretty much tried refreshing it using all possible ways but I still have to click twice on the ListBox for my DataGrid to be refreshed. This is the snippet of code that is meant to update my DataGrid and that is executed when the value of the ListBox changes - maybe you can find the error ? *** private void refreshProductsDataGrid() { string currentCustomerID = listBoxCustomers.SelectedValue.ToString(); { //filter only products from customer that was selected in listBoxCustomers DataView filteredDataView = new DataView(); filteredDataView.Table = _CustomersDS.Tables["productsTable"]; filteredDataView.RowFilter = "customerID=" + currentCustomerID + " AND productID NOT LIKE '7%' AND productID NOT LIKE '450'"; filteredDataView.Sort = "products"; filteredDataView.RowStateFilter = DataViewRowState.CurrentRows; dataGridProducts.DataSource=null; dataGridProducts.DataSource = filteredDataView; dataGridProducts.Refresh(); } } *** The main "problem" here is that the customerID changes, so I need some way to let the DataGrid know that. So I tried to changed the DataGrid's source to null then back to the dataview and then refresh. Seems it's not enough. Any other way to refresh it perhaps ? Thanks heaps! jez >>>> From: Ginny Caughey [MVP] (ginny.caughey.online@wasteworks.com) Subject: Re: HELP!! ListBox_SelectedIndexChanged Newsgroups: microsoft.public.dotnet.framework.compactframework Date: 2004-01-08 07:59:51 PST jez, > By "directly" you mean using lblcustomerID.text="007" ? Is there any way I > can automatically change a label without databinding ? Yes, this is what I had in mind. You could write your own form of databinding based on events, but this might be overkill. In one of my apps some of the controls are bound to my own data objects, but those data classes also have code to send notification back to the GUI whenever the state of their data changes to perform other actions. I ended up writing a bit more code than I expected, but now everything works the way I want. I wouldn't use this approach in every app though. ;-) > There's the ListBox that selects a customer and since the customerID is > bound to the listBox the customerID label also changes automatically. > Wouldn't mind trying to update the customerID label another way, just don't > know how.. This sounds like a good approach to me too. But if it's not working the way you want, then you have to look for workarounds. The best advice I can give you is to try to find out why the databinding isn't working the way you expect. If it looks like a .NetCF bug, be sure to let us know. And if looks like just the way databinding is designed, then try some things to workaround the limitation. -- Ginny Caughey .Net Compact Framework MVP Tag: switch a member from const to variable and viceversa Tag: 17740

    - Height of String or BMP in pixels .......... Urgent ....... Urgent Hi, I am developing an application for PDA for Windows CE environment. I am using Bitmap and Graphics object to create a bitmap. This BMP will have a 3x3 matrix on screen and have to place some text or image in each cell of the matrix. The height of text or image may vary and that's why I need to calculate the height of a string before drawing so that I can have the coordinates of next cell on screen. I just need to know the following two things: 1- Is there any API or function/procedure in .NET CF library which return me the height of a string in pixels or any other unit? 2- Same with the physical bitmap file (.BMP file) i.e, any API or function/procedure which return me the height of stored .BMP file?

    - Calling a web service from Multi-threaded application Hi All, I'm attempting to call a web service from different threads from within my compact framework application. On one thread it throws an exception saying it is "unable to read data from the transport connection". I read some where that there are issues with the soaphttpclientprotocol object returning the appropriate data to the appropriate thread. Can this be confirmed...? If so, is there a work around?

Hi group

I have a variable that i need for some time to pass to a const variable (It
is a sav buffer, to prevent lost of data.)
Then after my traitement, i need to repass it to a no const varable.

It possible to switch the const attribut as well ??

thank
ROM

No, the point of a constant is that it never changes. If you will *ever*
change it, it needs to be a variable.
