    - How to say "Shared" and "Overwrite Newer Only" for controls? In an INF file[1], you specify that a control is "Shared" by giving it the 0x80000000 flag, like so: "Adosync.Dll",,,0x80000000 But how do you tell it to automatically overwrite a control ONLY if it is newer than the one on the device (as well as having it Shared), and otherwise not overwrite any of them, and not ask any questions when the CAB is installing? According to the MSDN (again, see [1] below), 0x20000000 means "Do not copy file if target file is newer." But does this mean a) it *will* copy newer ones automatically, WITHOUT asking, b) the older ones *won't* copy, again WITHOUT asking, and c) the combo of "Shared" and "Overwrite Newer Only" is 0xA0000000? (i.e., 0x80000000 ORed with 0x20000000)? Any help on this will be greatly appreciated. Many thanks!

    - WINCE.NET 4.1, 4.2 and VS.NET 2003 Connection Together with my new Visual Studio.NET 2003 i made following experiences: 1)I cannot connect VS Studio via Active Sync with Wince.net devices without using one trick: First i select a PPC Device and i will get a "connect" Then i select Wince.net device and the connection is OK. 2.The wince.net images contain .NET runtime components but the VS deploys those components again, but non- persistant as it is deployed into the ram-filesystem. It seems, that programs, which are deployed manually are running without copying the runtime components from VS.NET 3. Having done the quarterly update to wince.net 4.2 the .net applications on the device do not even run if the the applications are deployed manually. 4. Removing the quarterly update confirm point 3. 5. As an extension to point 1: Even depoyment of software is possible choosing a PPC Device instead of a WINCE.NET device. The deployed software seems to run correctly. Has anybody made the same experiences ? Any hope to connect and deploy choosing the right device without deploying the instant .net framework inside the wince image again ? Tag: how do you serialize to xml Tag: 4674

    - ImageList Problem I am having a problem with VS 2003 and images, or resources, or the ImageList. It doesn't matter how many different lists I have, but somewhere between 18 and 28 images I get an exception in the initialization portion of the form. The exception always shows up on the line after the last resource is loaded. I have seen a very similar problem in VS 2002 when targeting PCs but with lots more images (200+). The exception doesn't give any additional information to pass on. I have worked around the problem by loading the images from files at runtime. My questions are: Is this a known problem? If so, is there another workaround? Thanks, Allen Tag: how do you serialize to xml Tag: 4660

    - AssemblyInfo.cs 0.0.0.0 OK... I have traced down the problem I was having getting the version of my application to the fact that the application is not calling the AssemblyInfo.cs in the project. I didn't even know this was possible. I discovered this by calling the version and getting back 0.0.0.0 even though I had set the version number to 1.1.1.6. How can I correct this?

    - Diffs between PPC2002 and Windows Mobile for PPC 2003 In 'My App' I have a button which when tapped minimises the app and when tapped and held closes the app. (The button is a version of the 'image button' posted around the CF websites, apologies to it's original author, I forget for now who posted the original) This works fine on PPC2002 but on WMforPPC2003 the area of the underlying Today screen beneath the button does not get redrawn, leaving initailly a ghost of the button in it's tap and hold state and subsequently a ghost of that portion of any other application run. I have tried various techniques to resolve this on theWMforPPC2003 device (in this case an Ipaq 2210) to no avail. My current app close code is in essence : Me.Hide() MySleep(500) ' A call to the API Sleep, in case 'things were happening too quickly' on the WMf0rPPC2003 device ' An attempt (successful) to destroy the window as all else seemed to fail Dim hWindow As IntPtr hWindow =FindWindow(Nothing, Me.Text) Me.Text = "" SendMessage(hWindow, WM_DESTROY,0,0) MySleep(500) ' Ditto Me.Close() To re-iterate all the above works fine on PPC2002 (in fact it works without the .Hide, the sleeps, and the window Destroy.... the simple .Close is enough) Any ideas anyone? Is it WMPforPPC2003, the Ipaq, the CF runtime. Having typed all this out, I've had a thought... could it be that the CF Runtime SP1 has been installed on the PPC2002 nad I need to force an install of it onto the 2003 device?

    - C# compiler not enforcing CLS compliance even with CLSCompliantAttribute In writing a custom control, I had put the [assembly: System.CLSCompliantAttribute(true)] in my code and received no errors when building using VStudio.net. When I compiled using the command line, (following MS's steps to be able to use the custom control from toolbox), I got several CLS compliance errors. I placed the attribute just below the last using statement. I also tried moving it to AssemblyInfo.cs (is that the best place anyway?) and still no CLS compliance errors in VStudio. Am I missing something, or do I have some kind of configuration issue? I didn't see anything helpful in the project build property page. Hank Tag: how do you serialize to xml Tag: 4531

    - How to create modal, SIP-like control? Essentially, we are trying to recreate a modal form on the compact framework. We want to create an application in which two forms will be open at one time, a parent and a floating toolbar. The user must be able to see and use either form without closing the other. The toolbar must be moveable and must float over the parent form. This is similar to the way the SIP works. There are a few issues: 1) how to resize a form? 2) how to keep two forms open and visible at one time? Easy to do in regular .NET, difficult in CF. Any ideas? Is eVC the only option?

However, if I change the band to 900/1800 MHz through GSMDemo (a program provided by Symbol that lets you change GPRS parameters), then after exiting GSMDemo I can no longer open the COM9 port using my code (included below - the GetDevice method is being passed "COM9:" as a parameter).

    - Rotating Text I need to draw text at diferent angles. Usually I'd use the Matriz class and then transform the Graphics object, but those do not exist in the CF. so, does anyone have an alternative method? Saludos Alfonso Tag: how do you serialize to xml Tag: 4412

    - Rotating Images I am working on an image viewer application as a learning exercise. Obviously I am making heavy use of the Bitmap and Image classes. In the full framework, there is a method called Image.RotateFlip() that would allow some trivial image manipulation. This method doesn't exist in the Compact Framework. Unfortunately, they also removed the LockBits method that would allow programmers to party on the image bits themselves. The only way I have found in the Compact Framework to rotate an image is by creating a second image of the correct dimensions and then walking over the first image calling GetPixel and then calling SetPixel on the new image. This is just about the most inefficient method of doing anything I have ever witnessed. To rotate a simple 74x124 pixel image on a 400MHz XScale, it takes approx. 1:30 minutes. The time to rotate an image 90 degrees appears to increase exponentially as the image gets larger. Does anybody have a better method of rotating an image with the Compact Framework? If not, then I fear it will be a big flop for the majority of applications, since trivial image manipulation is a fairly common thing. Especially with games!

    - Campaign for KeyDown I'm trying to intercept the arrow and return keystrokes with the KeyDown event. Yes, I've tried the McSoft package and it won't work for me. I believe a TextBox and only one or two other controls make the KeyDown event available. For my testing, added a handler to a textbox's KeyDown event. Upon each event, I added the KeyCode to a combo box. I found some interesting results which I am happy to share here. In all tests, I set the focus to the textbox and pressed the Up, Down, Left, Right and Return keys in order. The test results show the KeyCode.ToString results generated from each physical key pressed. Note that in some cases, one human action produced two events (i.e. two keypresses were generated). Test 1: Emulator; clicking the star pad with the mouse Up, F21 Down, F21 Left, F21 Right, F21 Return Test 2: Emulator, clicking the arrow keys on the SIP Up Down Left Right Return Test 3: Emulator, pressing keys on the host computer Up, F20 Down, F20 Left, F20 Right, F20 Return Test 4: Compaq iPaq, tapping keys on the SIP Up Down Left Right Return and a beep Test 5: Compaq iPaq, pressing the star pad Up, F21 Down, F21 Left, F21 Right, F21 F23, Return and a beep And that leads to a few questions: 1) What's with the the F20, F21 and F23 keycodes? What do they signify? It would make some sense if the F## keystroke always preceded the usual keycode (so the software could perhaps handle the star pad differently from the SIP), but it's a real kludge if the F## keystroke follows the usual keycode. 2) Can I get rid of the beep? I tried setting AcceptsReturn both ways on the textbox and that didn't seem to affect the beep. 3) What other controls support KeyDown detection? 4) Design question: I've got a tab control with 4 tab pages. The tab page of interest to me has a bunch of buttons, combo boxes, trackbars, etc. There's also a bunch of combo boxes and list views that are outside the entire tab control. I don't need the SIP for any of these controls. I'd like to use the Up/Down/Return keys from the star pad. What do you think about this approach: * deriving a class ("MyGizmo") from one of the controls that supports KeyDown (probably not the TextBox since it beeps for Return) * instantiating Gizmo on the tab page of interest * setting the Gizmo invisible (or, if it must be visible in order to get focus, then creating a 1-pixel screen representation) * adding a handler to all the other screen controls' GotFocus event to send the focus over to the Gizmo control * adding a handler to the Gizmo KeyDown event; if the tab control's selected tab page is the one I'm interested in, and the keycode is one of my special keycodes, then do whatever needs to be done and mark the keycode as handled Boy, I sure wish I had a form-level KeyPreview....

how can you serialize an object's state to xml in the
compact framework? do you have to do it manually, create
your xmldoc and save it? or is there an easy way? I don't
see an XmlSerializer object in the framework.

thanks,

There is no built in Xml Serialization for any class in the .NET CF except
for the dataset.

You can build your own XML serializer using reflection without too much
trouble, though I don't have any sample code available. Several of the
books floating around do have such a sample application - I specifically
know .net compact framework kickstart (SAMS) does

Hope this helps
