    - Strang bug with the modal dialog Hi, I am building application that collects data. I am using listview to show multirow data and by clicking add/edit buttons, user can get another form to enter/edit the data for the selected row. I am using a non-fullscreen (borderless) form for the purpose. If I show this dialog form modally (using ShowDialog), I encounter following problems :- 1. If I set the dialog's parent to the main form and use ShowDialog method then the dialog is shown in background. 2. If I don't bother to set parent property then ShowDialog shows the dialog modally and in foreground. I cannot do any UI action on the main form (thats excepted) except whenever focus is on main form, taskbar display's title for that form. 3. I am creating all my dialogs at the application load time and I display a non-modal statup screen while application is loading. The funny thing is whenever code setting dialog's border to none (in dialog's constructor) executes, taskbar's caption flickers (i.e. it switches to "Start" then comes back to "App Title"). 4. I am using custom control that has combobox like interface. So whenever user clicks on an arrow button, it popups a non-modal form that allows user to select some option. If user clicks anywhere else the form gets closed. Now on my main form this control works absolutely fine. But on the dialog form, when the control-form is popped up for the first time, it is unable to receive any click event. Clicking onto it produces beeps; howvever afterwords (i.e. after closing it at first time) it works as it should. 5. To use dialog non-modally, I have to disable the main form and it looks ugly. Any solutions/workarounds/alternate solutions will be appreciated. Thanks, Vinay. Tag: DrawReversibleFrame Tag: 4725

    - 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: DrawReversibleFrame 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: DrawReversibleFrame Tag: 4660

    - 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?

    - 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.

    - Frame Rates in Games I am in the midst of porting my Personal Java game to C# and the Compact Framework. I'm just starting to get it working, but it's running very slow so far.

I'm not very experienced with C#, but I'm using the same drawing concepts that I used in the Java version (double buffering with background thread). Perhaps I need to use a different approach with the Compact Framework? What kind of frame rates have other people achieved? I'm using an iPAQ 3835 @ 200 Mhz.

constantly erase underlying rectangles/lines?
