• Visual C# Time

  Okay, so I am trying to make an alarm clock program for computer, to familiarize myself with C#. What I need help with, is I have the dateTimePicker tool for setting the alarm, and I have a label for displaying the current time. My coding problem, as it were, is that I cannot figure out how to make the label display the current time, or how to get my program to play the music when the time comes around. I already have the ability to open a file, and have set the file filters for WAV, WMA, MP3, MP4, and MIDI files. so, my program can open files, but of course, at this moment, it cannot use them. Any help would be greatly appreciated. you need to add the COM component into your application, right cl ...Show All

• .NET Development Abortable thread with return value

  Hello, There are two possible solutions that would work for me here... Requirements are as follows: I want to run a task in the background. The task returns a value, which I need to collect. I also need to be able to abort the task. I can use Thread.Start, and then Thread.Abort if I need to stop it, but I can't find a way to get a return value by this method. Alternatively, I can use BeginInvoke, which makes it easy to get a return value using EndInvoke, but then I can't seem to find a way to abort the thread. Either method would be fine. Any suggestions Thanks, Nick I'm running into a similar issue, on Sybase ASE 12.x. Calls to OleDbCommand.ExecuteScalar() occasionally never return - th ...Show All

• Windows Forms selecting display/screen device for form how?

  I'm working with a multi-head system and would like to position my application form on a display other than the primary display when it is created/Show()'n for the first time on application startup. How is this done Thanks Tyler To show a form on a specific monitor all you need to do is to set the location of the forms so it is in that monitor display bounds. To get the bounds of a monitor you can use the Screen class: // This the position of the form relative to the top left corner of the monitor where you want your form to show up Point formLocation = new Point (100, 100); foreach ( Screen screen in Screen .AllScreens) { // You need to know the name of the device to whic ...Show All

• Smart Device Development AVRCP

  Any help in finding documentation on how to use AVRCP in C# CF 2 appreciated :) Microsoft BT stack APIs are described here  (WM 5.0) and here  (CE 6). I’m not sure if this profile is even supported though and if it is it might be up to OEM to support it or not. If you happen to have 3 rd party BT stack you’d need to contact that 3 rd party to obtain documentation and/or SDK. Link #3 points to one of these manufactures. ...Show All

• Visual Studio Team System Data Generation - Unable to bypass circular references

  I'm trying to create a generation plan for my database but keep hitting the problem of "Table <x>: The Data Generation plan contains a circular reference. Population cannot continue". Note that I didn't design this database There are two tables, Survey and Property. Survey is many-to-one related to Property, and so has a foreign key of the PropertyId On Property there is a column called SurveyToUse which is a foreign key to Survey. Apparently there is nothing I can do to avoid the error. In theory, I should be able to deselect generation of the SurveyToUse column in Property (it's nullable), which will avoid the circular reference. Sadly this doesn't work. Is there anything I can do to get around ...Show All

• Software Development for Windows Vista How to prevent Explorer to open the "Prepare this disc" dialog

  Hello, I'm working on a tool to mount arbitrary sessions on a multi session disc. It works fine on W2k and XP. On Vista, it also works fine, as long I issue my mount commands via a command line application. Using a shell extension on Vista with a recorder device, quite frequently causes Explorer to open the "Prepare this disc" dialog. Clicking Next and confirming disc preparation usually damages the media. Question: How to avoid Explorer from opening this dialog Hello garrett, for a first test, I disabled autorun permanently via registry - it didn't help at all. I guess, that 'IQueryCancelAutoPlay' will have no other effect, except it dynamically allows to reject autoplay, so I didn't impl ...Show All

• Windows Forms Closing original Form

  If I have a startup form that allows the user to open other forms is there a way to close that original form or hide it until the user needs it again Thanks Thomas you would need a reference to the first form in that case if you want to show it again if its hidden. you could use a ShowDialog() when showing other forms from the caller, as this will make sure the user cannot access the forms underneath until they close that form. Is this a better solution you are after perhaps ...Show All
