Any new ideas or comments? regards, George Re: Thread safe issue in string operation Abhijit Jana5-Jan-09 4:08 Abhijit Jana 5-Jan-09 4:08  George_George wrote: It talks about the general thread safety rule Yes, That true. but it could also clear your doubts . Any way hope now your have got your answer. cheers, Abhijit Re: Thread safe issue in string operation George_George5-Jan-09 22:41 George_George 5-Jan-09 22:41  Thanks Abhijit, I think all string operations are thread-safe. Since when we modify a string, a new string instance will be created. Do you think it is correct? regards, George Re: Thread safe issue in string operation Abhijit Jana6-Jan-09 0:55 Abhijit Jana 6-Jan-09 0:55  George_George wrote: Do you think it is correct?

That makes your tally, what, like a couple of thousand now? Re: Thread safe issue in string operation George_George5-Jan-09 3:28 George_George 5-Jan-09 3:28  Thanks J4amieC, After some reading the investigation, I think my understanding is correct. Do you agree? regards, George Re: Thread safe issue in string operation J4amieC5-Jan-09 3:33 J4amieC 5-Jan-09 3:33  Yes, and no. Mostly yes, but partially no.

Re: Thread safe issue in string operation George_George5-Jan-09 22:43 George_George 5-Jan-09 22:43  I think the reason why all methods of string class are thread safe is because string is immutable, i.e. when the string is modified, a new instance is created. Agree or? regards, George Re: Thread safe issue in string operation Jon Rista6-Jan-09 11:53 Jon Rista 6-Jan-09 11:53  OMG dude...you already have the friggin answer. You've been told the answer is correct several times already. Your request for agreement has been fulfilled already. WHAT MORE CAN YOU POSSIBLY EXPECT?

I am adding label object to property grid and want to show some specific property of label. But propertygrid shows all properties. Please help me out how can i skip some property of label. Thanks in advance. Re: Remove items from property grid Dragonfly_Lee5-Jan-09 4:01 Dragonfly_Lee 5-Jan-09 4:01  I am afraid we can not do this for defined control, such as Textbox. But we can set the visible property for custom control(e.g. MyTextbox) via Browserable attribute. If we want to expose some certain property from Textbox, we can hold the reference in MyTextbox object. For example: class MyTextbox { TextBox textbox; public string Text { get { return this.textbox.Text; } set { this.textbox.Text = value; } } } Hope this will help you ~ Tan Li I Love KongFu~ 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. Re: How to detect .net Framework 3.5 is installed or available Member 44703545-Jan-09 2:16 Member 4470354 5-Jan-09 2:16  The following code will give you the list of available versions. const string regLocation = "SOFTWARE\\Microsoft\\NET Framework Setup\\NDP"; RegistryKey masterKey = Registry.LocalMachine.OpenSubKey(regLocation); RegistryKey tempKey; string[] SubKeyNames = masterKey.GetSubKeyNames(); for( int i = 0 ; i < SubKeyNames.Length ; i++ ) {tempKey = Registry.LocalMachine.OpenSubKey(regLocation + "\\" + SubKeyNames[ i ]); MessageBox.Show(SubKeyNames[ i ]); MessageBox.Show("\tVersion = {0}", tempKey.GetValue("Version").ToString()); } Or you can check the currently user version using the following. 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.
