How to detect .net Framework 3.5 is installed or available Seraph_summer5-Jan-09 1:32 Seraph_summer 5-Jan-09 1:32  It is known that some functions are supported by .net Framework 3.5. therefore, how to detect automatically that .net framework 3.5 is already installed on the current computer? in order to give the message to the user when the user try to use some functions only supported by .net framework 3.5? thanks.

I'd hate to have an application tell me "You can't use feature x because you don't have MyWizzyFramework 3.91 installed." Put the .NET Framework as a required resource in your setup project so that it is installed up front (if they don't already have it installed). "WPF has many lovers.

I just want my application more flexible to the user, he can select which function he want to use.

MessageBox.Show(Environment.Version.ToString()); Re: How to detect .net Framework 3.5 is installed or available Jon Rista6-Jan-09 14:53 Jon Rista 6-Jan-09 14:53  Environment.Version always returns the CLR version, not the current framework version. For .NET 2.0, 3.0, and 3.5, Environment.Version returns 2.0.50727.3053, since 3.0 and 3.5 are just API extensions to 2.0. Unable to dynamically create HTML tables Brian_Ho_08235-Jan-09 1:29 Brian_Ho_0823 5-Jan-09 1:29  Dear All, I need to prepare printable coupons for my clients but don't know how to use the same template to make multiple copies. The number of coupons the client needs depends on the number ordered. I have designed a coupon template in html table format. How can I create multiple copies using only 1 template? Thanks for that. Re: Unable to dynamically create HTML tables Ben Fair5-Jan-09 4:24 Ben Fair 5-Jan-09 4:24  You should post this type of inquiry to the Web Development forum. I've accomplished this using the Repeater control in ASP.NET. You can use the <%# ... %> syntax in the ASPX page to plug in record data; do a little Googling on the subjects and you should be set. Keep It Simple Stupid! (KISS) null value? dec825-Jan-09 1:24 dec82 5-Jan-09 1:24  public class Command { public int Number; public int NoOfParameters; } Command[] Querries = new Command[50]; private void button_Click(object sender, EventArgs e) { initialization() Device mydevice = new Device(); int Add = mydevice.FindAddress(); } public int FindAddress() { SendCommand (Querries[0]) } My initialization method already initialize all Querries[i].Number and Querries[i].NoOfParameters. But when the code is run to SendCommand (Querries[0]), the values of Querries[i] is still null? Why is it so, and how to solve it ? Thanks Re: null value? SeMartens5-Jan-09 1:33 SeMartens 5-Jan-09 1:33  Hi, how does your initialization()-method look like? Maybe you could post the code, this could help us to find the problem.

Jean-Christophe Grégoire Re: null value? dec825-Jan-09 3:50 dec82 5-Jan-09 3:50  private void initialization() { Command[] Querries = new HARTCommand[50]; XmlDocument Reader = new XmlDocument(); Reader.Load("Myfile.xml"); XmlNodeList List = Reader.SelectNodes("/Common/Command"); foreach (XmlNode commandnode in List) { int i = int.Parse(commandnode.Attributes["value"].InnerText); int type= int.Parse(commandnode.Attributes["Para"].InnerTect); Querries[i] = new Command(); Querries[i].CommandNumber = i; Querries[i].NoOfParameters= type; } } I run the code ,and the initialization is working fine. Re: null value? dec825-Jan-09 4:17 dec82 5-Jan-09 4:17  sorry, corrected one is here private void initialization() { Command[] Querries = new Command[50]; XmlDocument Reader = new XmlDocument(); Reader.Load("Myfile.xml"); XmlNodeList List = Reader.SelectNodes("/Common/Command"); foreach (XmlNode commandnode in List) { int i = int.Parse(commandnode.Attributes["value"].InnerText); int type= int.Parse(commandnode.Attributes["Para"].InnerTect); Querries[i] = new Command(); Querries[i].CommandNumber = i; Querries[i].NoOfParameters= type; } } I run the code ,and the initialization is working fine. Re: null value? J4amieC5-Jan-09 5:01 J4amieC 5-Jan-09 5:01  The problem you have is because "Querries" is defined as a class-level property, but you're redefining it as a local variable in the initialization method. This locval copy is the one you're initializing, not the class-level one you go on to try to use. Re: null value? dec825-Jan-09 19:18 dec82 5-Jan-09 19:18  thanks , but Even if i put whole dose of initialization inside button_Click(object sender, EventArgs e), it is still the same ? Re: null value? dec826-Jan-09 0:53 dec82 6-Jan-09 0:53  Thanks, ALready solve it Re: null value? #realJSOP5-Jan-09 2:30 #realJSOP 5-Jan-09 2:30  There must be dozens of your classmates that have already asked this question here. Just because you make the space for 50 instances of your object, doesn't at all mean that you've instantiated the object 50 times. For christ's sake, read your freakin' text books.

Dragonfly_Lee5-Jan-09 18:07 Dragonfly_Lee 5-Jan-09 18:07  Do not be mad. In fact, the real problem is that the var he defined in Initializer method override the class field. Maybe the code is not clear enough.

Your other option is to rebuild the PC, since this is a really strange problem. I've never seen this happen before.
