Re: DateTimePicker Custome Property... Alan N13-Jul-09 3:05 Alan N 13-Jul-09 3:05  Hi, You have probably made simple mistake in the format string. The following will output e.g. 2009/07/13. Note that you have to enable custom formatting via the Format property. dateTimePicker1.Format = DateTimePickerFormat.Custom; dateTimePicker1.CustomFormat = "yyyy/MM/dd"; Alan.

Now it works well. reading data sent through GPRS in C# Member 305788713-Jul-09 2:05 Member 3057887 13-Jul-09 2:05  Hi, I am working on a project involving communication using GPRS. We have a GPRS enabled modem that sends data to server at regular intervals. All I have to do is develop a service that reads the data sent from GPRS enabled modem and save into database. I request any one who has experience in these type of projects to guide me in three things. 1.How to establish connection between Modem and Server 2.How to read data received by the server 3.How to close the connection Thanks in advance Re: reading data sent through GPRS in C# Jimmanuel13-Jul-09 3:37 Jimmanuel 13-Jul-09 3:37  Your question is way too broad for a specific answer; in general terms the answer is this: 1) figure out how the device is sending data (read the documentation) 2) code your service accordingly I'm doing the same thing right now - here's what I encountered. Our devices are configurable; we chose UDP sockets as our preferred communication method so we programmed the devices with the required commands and then used this[^] in a service on the server to read incoming data. The other option was to use TCP/IP in which case we would've used this[^] and this[^] on the server to receive data from the devices. All of those classes have methods for opening and closing connections (if applicable) and reading data. We ruled out comms via SMS on a cost basis. Hope that helps.

} Instead write an event. When one song is completed, fire that event within WndProc if (lEventCode == EC_COMPLETE) { m_objMediaControl.Stop(); m_objMediaPosition.CurrentPosition = 0; m_CurrentStatus = MediaStatus.Stopped; UpdateStatusBar(); UpdateToolBar(); // Fire that event } Then clean up and start the next song.

I have tried with Random Class like private int RandomNumber(int min, int max) { Random random = new Random(); return random.Next(min, max); } Inside for loop i am having the following line; int returnValue = RandomNumber(0, 1); It's returning all 0's. Is any other method to use. Thanks, Subbu Re: how to generate 0's and 1's only through Random Class...

Anindya Chatterjee13-Jul-09 2:48 Anindya Chatterjee 13-Jul-09 2:48  Create a StringBuilder object. Append that random number to the object in an iteration. After desired iteration just use ToString() method of StringBuilder object and it will create a sequence like that.
