System.Net.Mail not working dptalt17-Jun-09 2:33 dptalt 17-Jun-09 2:33  I cannot get the System.Net.Mail to send out an email message from my Windows application. The Try Catch reports an the error message 'Failure sending message'. What is causing the error? Below is the code I'm using. MailAddress objFromMailAddress = new MailAddress(fromemailaddress, "Test"); MailAddress objToMailAddress = new MailAddress(toemailaddress); MailMessage objMailMessage = new MailMessage(objFromMailAddress, objToMailAddress); objMailMessage.Subject = "Subject"; objMailMessage.IsBodyHtml = false; objMailMessage.Body = "Email message"; NetworkCredential objNetworkCredential = new NetworkCredential(outgoingusername, outgoingpassword, "smtp.1and1.com"); SmtpClient objSmtpClient = new SmtpClient(); objSmtpClient.Host = "smtp.1and1.com"; objSmtpClient.Port = 110; objSmtpClient.UseDefaultCredentials = false; objSmtpClient.Credentials = objNetworkCredential; try { objSmtpClient.Send(objMailMessage); } catch (Exception pError) { } Re: System.Net.Mail not working Rob Philpott17-Jun-09 2:38 Rob Philpott 17-Jun-09 2:38  Not so well up on the Mail namespace, but port 110 is POP3. Presumably you want port 21 for SMTP. Regards, Rob Philpott. Re: System.Net.Mail not working Dave Kreskowiak17-Jun-09 8:24 Dave Kreskowiak 17-Jun-09 8:24  SMTP is port 25, not 21.

What else could be wrong? pass '' char to storedprocedure !!!!!!!!! zeeShan anSari17-Jun-09 2:20 zeeShan anSari 17-Jun-09 2:20  hi all, i have stored procedure it has some varchar(1) variable. when i execute on sqlserver management studio as EXEC exs_clearance @from ='20090316', @to ='20090316', @side = '', @symbolType = '', @symbol = '', @client = '', @account_auto_num = '', @csv = '1', @sp_instructions = '', @show_sp = '', @adp = 'ridge', @clrFirm = '' than it gives some outputs. but when i execute from winform through LINQ datacontext as dataGridView1.DataSource = Context.exs_clearance("20090316", "20090316", "",'\0', "", "", "",'1','\0', '\0', "ridge", "").ToList(); than it returns zero row..........why? how can i get data? Re: pass '' char to storedprocedure !!!!!!!!! MohitBhambral17-Jun-09 2:32 MohitBhambral 17-Jun-09 2:32  hello dear Mohit Here Please Send me a some detail of this like if you want total fields that are in exs_clearance then you just write Context.exs_clearance().toList(); other wise get Id or any object so that you find record for particular record. otherwise send me a detail i'l surely solve your problem.. regard: Mohit Bhambral, +91-9815645999 Re: pass '' char to storedprocedure !!!!!!!!! zeeShan anSari17-Jun-09 2:47 zeeShan anSari 17-Jun-09 2:47  exs_clearance() has 8 arguments so Context.exs_clearance().toList(); is not possible. my problem is that how do i pass the empty character which are varchar(1) variables to the exs_clearance storedprocedure thanks Pass null to stored T-SQL Proc via LINQ ProtoBytes17-Jun-09 2:56 ProtoBytes 17-Jun-09 2:56  My guess is it is your use of null literal characters '\0'. LINQPad is a good tool that will help you debug, your LINQ problems. Another good tool(s) are the visualizers for LINQ and Lambda expressions. It will show you the outpus and inputs and how they are translated by the intermediate LINQ expression builder. Try sending a null literal using the key word 'null'. Or try modifying your T-SQL to convert the '\0' into a SQL null or empty.

Re: Pass null to stored T-SQL Proc via LINQ [modified] ProtoBytes17-Jun-09 4:20 ProtoBytes 17-Jun-09 4:20  Sounds like you are running into a loop on the db. LINQPad should return the result in the same time it takes the C# to execute. Does your LINQ side query do any pre processing before handing off to the db for SQL processing? Or are you using the SProc wrapper built by the LINQ ORM mapper? The visualizers also allow you to directly enter inputs to the DataContext. You might also try a simple query in LINQPad to verify that your DataContext is properly mapped. You must map the DataContext to your ORM. Additionally, you might need to make a refrence to the context in LINQPad so that it can find all the dependancys of your project. Ie. anything not included in the .NET Framework you are using, all of your 'Includes' spicific to your project. LINQPad is smart, but it will not tell you that an object refrence is not found in the expression builder. Use the half split method of tracing down the problem. modified on Wednesday, June 17, 2009 1:02 PM Crystal Report rema r17-Jun-09 1:38 rema r 17-Jun-09 1:38  Hi all, How to set dynamic database connection to crystal report. for eg all reports get connection from web.config file or from class file. Now, we are creating connection for each report, and its given at design time. is it possible to dynamically apply the connection string from config file to all the crystal reports.
