• Jarodtweiss How to access the controls created in Main thread from a worker thread?

  Hi All, I am developing an application for PocketPC in C#.NET, VS2005. It contains a form and few buttons. When the application starts, an worker thread will be created. At certain point of time during the course of execution, the worker thread will be trminated. Before terminating the thread, I have to set the 'visible' property of a button to 'false'.. When I try to do that inside the worker thread, it is raising the following Exception Control.Invoke must be used to interact with controls created on a separate thread. How can I be able to access the property of the button created in main thread from the worker thread... Thanks Ilya.. Control.Invoke() rectified my problem... ...Show All

• ozhonetech Virtual Earth and Mail Merges

  I would like to create a mail merge and take the home address and create a "driving directions" map that pulls the appropriate "map graphic" route into the body of the e-mail/print/letter. I thought the Virtual Earth product would fit the bill and didn't want to re-invent the wheel. Any advice welcomed.   Mick- I was starting to suspect that VE is too realtime for this application. I may try to batch render a Perma Link to my list and create an embedded link that would be called up in Word. Interesting idea. VE is not like other maping systems, like Mappoint, in that it doesn't generate a single image rendered on the server. Instead it is a fluid control built with map tiles and layers of pins and polylines. S ...Show All

• MatthewFisher Vista, VS2005 SP1, Mobile Device Center and disconnects

  Situation: I had to install Vista Ultimate x64 I installed Visual Studio 2005, SP1. Both in Italian. I could not install the "Service Pack 1 Update for Windows Vista " because it is available only for English. To work with my PDA, I installed "Microsoft Windows Mobile Device Center Beta 3 for Windows Vista (AMD64)". I'm able to sync my PDA with my PC. The problem: When I run my VS2005 VB application, it is correctly distributed on my PDA. BUT, as soon as it load the symbols for debugging, the PDA gets disconnected from the "Windows Mobile Device Center" (but NOT from VS 2005!!) This happens randomly, but about 4 times out of 5. I can debug my application, but since my application is tryin ...Show All

• rebelR Application loses focus when closing a Form - but only on one Form it happens...

  Hi all, I have this strange problem/issue that I have had bothering me for a while now. I have an application where the users browses through Forms to perform various bits of functionality, and then closes the form to return back to the previous form (the Form from which it was openned), and the Focus is right back with the Form that openned the closed Form (if you know what I mean :)). Now this all works fine in my application apart from in one place, where when the called Form is closed, the calling form (or my Application even) doesn't get focus back until the 2nd tap on the application with the pen. The Windows start button and Input control on the MainMenu are focused and can be activated from the first click on them, but not my appli ...Show All

• brad1 Device Driver Development (how to communicate w a device driver?)

  Hi, I have been looking at how to develop a device driver for the past few months and have a few questions. I was looking at the WDM sdk, namely wdm/hid/firefly sample code. 1. Apart from using WMI to communicate to the from the dll to the filter driver, is there any other way to allow a dll to communicate with a Driver Also, is WMI a secure method to communicate with a Driver 2. It seems that i cannot identify the device driver symbolic name after it has been loaded by the device manager. If i load it using system apis, i can send irps to it. But if i load it to a device say a mouse, I cannot find the correct symbolic name. Is there some way to get it Check out WinDriver - device driver developmen ...Show All

• DotNetDotNet Embedded Visual C++ using Visual Studio 2005 running on VISTA RC1: Linker errors

  I'm using Visual Studio 2005 running on VISTA RC1 to create a simple Smart Device application. *using Embedded Visual C++(Windows CE and Platform Builder are both installed) *to access the RIL(Radio Interface Layer) of WinCE. The target device is a PPC phone (HTC with an OMAP ARM processor). I have an eVC++ source program, the RIL.h and RilClass.h headers, and Ril.lib(to import the ril functions from the ril.dll) When I 'build solution' I'm getting a ton of unresolved external symbols. I suspect that I have not sucessfully included the ril.lib into the build process, and that that is causing the unresolved externs: 'error LNK2019' and 'error LNK2001'. How do I specify that the .lib is to be used when linking my eVc++ pr ...Show All

• Jay Thomas Trying to use lineMakeCall()

  I am writing an application for a Windows Mobile device that makes voice calls and is able to send DTMF tones once the call has been established. I have been trying to port the Tapi2Lib library over to the Compact Framework V2 platform. Everything seems fine until I call lineMakeCall(). Once I do, I get a call request id of -2147483595. I run the GetLastWin32Error() method and it returns a value of 6. When I call GetLineDevStatus() I get LINEDEVSTATUSFLAGS_CONNECTED | LINEGETDEVSTATUSFLAGS_INSERVICE. That is the same status if I run that method after invoking the lineOpen() method. I do not understand what I am doing wrong. The lineOpen returns with what appears to be a valid, open line.

• tackett CTreeView & MouseUp/DoubleClick malachie....

  Hi Guys! Me again on my endless journey to understand the .Net Compact Framework 2.0. The following problem: I have a treeView that fills a complete form. The user should navigate through the treeView on the PocketPC via Up/Down menu buttons or using the Stylus. On a Smartphone device just by using the Up/Down menu. Only when an already selected treeViewNode is tapped again with the Stylus or receives another Menu key entry, another Form should popup. Well i solved the problem for Smartphone by using the AfterSelect event to set a flag, which is cleared in the KeyUp event. Only on the next KeyUp event, if this flag is not set, the new Form pops up. Works like a charm, but obviously a KeyUp event is not a MouseUp event nor a DoubleClick eve ...Show All

• Terence Curd How to prevent user from powering off the PDA

  Dear all, I'm working for a communication program. I found if I power off the PDA when my program is in 'talking' state (sending and receiving RTP packets using socket), the system will be frozen and dead when I power on. So I decide not to allowed user to power off during talking. I could use SystemIdleTimerReset() to disable auto power off, but I don't know how to prevent the 'manual' power off. I know there must be a way, because I see Tomtom could do it. Could anyone give me a hint Thanks in advance! Yun I've found some stuff on power.  Namely the POWER_ACTION_POLICY in which it looks like you can change your the way in which a power down will occur.  I guess alternatively, you could somehow change the po ...Show All
