• Visual C# Help me understand how to get time to calculate trial using of applications?

  Several applications allow users using them (trial using). If I change my date on my computer they still count date exactly. Now I want to write an app using this technique but I do not know how to do that. Please tell me how I can write this for my app. Thanks in advance! Save the bios time,when ever application runs in ur application specificatio file in some encrypted format so that user cannot understand ofcourse cannot change it.He/She may try to delete the file. Allow the exe to get run ,if the file exists and if the current bios time is greater than or equal to time in the fie. Hope it works out.Revert back ,if any thing is obscure. Thanx, Ch.T.Gopi Kumar. ...Show All

• Smart Device Development IO.Ports.SerialPort - issue with .BytesToRead and DataReceived Event

  Hi Folkes! I'm currently developing an infrared IR-communication software for PocketPC's with Windows Mobile 2003 SE and Windows Mobile 5.0 The communication is based on:    PocketPC virtual serial-port --> IR    and    IR --> Device serial-port. I wrote a communication-library for windows first, which worked perfectly with a real serial conncetion (no use or IR). The same code should work for the virtual serial-port and IR, since it's only a simple IR serial-bridge. Here comes the issue: It's possible to write data from the PocketPC to the device with .Write() It's possible to read data from the device with .Read() and similar. BUT: it's not possible to dertermine how may b ...Show All

• Windows Forms TabControl always disturbed by custom control in same project?

  Hi, Using Visual Studio pro 2005, C#. I thought to have discovered a nice IDE feature: Step 1: create a basic windows application. Step 2: add a class to the project. Step 3: have this class derived from System.Windows.Forms.Panel (this is the only manual change you do). The class looks like this: namespace WindowsApplication1 { class Class1 : System.Windows.Forms. Panel { } } That's all. After "Build solution" a new tab appears In the ToolBox called "WindowsApplication1 Components". Great, because now I can drag and drop my on-the-fly control like all other controls. However: Step 4: dragdrop a "Class1" control onto your form (no problem there). Step 5: dragdrop a TabControl onto yo ...Show All

• SQL Server Test linked server connection SQL 2000

  I’m trying to resolve an issue and wonder if anybody has ever run into and possibly had a resolution for. I wrote a custom conflict resolvers to manage data at the column level. What I needed to do to achieve this was to use a remote query to the mobile subscriber that raised the conflict. I’m trying to put in a rule that if there are any issues connecting to the subscriber I want to use the default conflict resolver and move forward. Here is my issue, it seems there is no way I can test a connection without getting a critical error that I can’t seem to trap. Example I was trying to do Select * from [linkedserver].[database].[dbo].[incident] If @@error <> 0 use default conflict resolver ...Show All

• Visual Basic createing a text file

  Hi...i used to play around with vb 6 and now i have 2005 and i gt say...i can learn chinese faster then i can learn it... can someone show me how to create a simple text file in the programs folder and can you explain the code so i can learn how it workts..thanks! Sure, you can post your code if you want to The example above was meant to be a little confusing, just to give you some more advanced stuff to learn from. I used an array of strings because you talked about arrays, but in fact, it would have been much simpler without array. As you saw, it's pretty easy to take a text that's one big string, and turn it into an array of strings that are split by the LineFeed character so each splitstring is a 'line' of the text - yo ...Show All

• Visual Studio 2008 (Pre-release) Binding to a service from xaml

  I'm having trouble figuring out how to bind to an object retrieved from a custom service locator where the key of the service is indicated in the xaml. For example, imagine I've exposed an object "ServiceLocator" to the namescope. I'd expect to be able to call: < UserControl x:Class = " UserControl1 " xmlns = " http://schemas.microsoft.com/winfx/2006/xaml/presentation " xmlns:x = " http://schemas.microsoft.com/winfx/2006/xaml " > < StackPanel > < TextBox Text = " {Binding ElementName=ServiceLocator, Path=GetService[CurrentUser].CompanyName} " /> </ StackPanel > </ UserControl > My ServiceLocator class has: Public ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Any tips on drawing a "control panel"

  I'm doing a simple little space shooter, and things are going fairly well. Ships are moving, planets are spinning, background stars are scrolling along. However, the one thing I haven't figured out is how to do a "control panel" to display information about the ship, the "mini-map" of star locations, etc. I can do this through sprites, by sticking a large sprite across the lower third of the screen, then mapping each star onto the map using a scaled down texture. However, this seems to be very wasteful. After all, action on the "main screen" needs to be updated as often as possible, but if I were to update the star map no more than once every few seconds, it would be fine. Some of the control settings need to ...Show All

• Smart Device Development Problem with TAPI lineDrop on smartphones (device Qtek 8500)

  I use TAPI lineDrop routine call to drop the call in DATA mode: - rc = lineDrop(hcall, NULL, 0); lineDrop returns a positive value and I call lineDeallocateCall to deallocate handle: - rc = lineDeallocateCall(hcall); lineDrop returns LINEERR_INVALCALLSTATE and it seems that call is not in the idle state. And after that my TAPI message handler doesn't receive any disconnect messages. TAPI message handler receive disconnect message only after other side droped the line. This problem appeares only on smartphone devices (Qtek 8300 and 8500). On PDA (HP 6515, Qtek s100, MIO A-70x) these routines calls work without any problems. What is specific in TAPI lineDrop and lineDeallocateCall calls on smartphone devices ...Show All
