You want to perform the validation server side in c# code behind right? Here is how I do it: [code=c#] public static bool IsValidEmailAddr(string email) { try { System.Net.Mail.MailAddress addr = new System.Net.Mail.MailAddress(email); } catch { return false; } return true; } [/code]

Open the gridview's smart tag and launch the column editor. Select the checkbox column and set the "ThreeState" property to false. See attached screen shot

Your code: [code=vb.net] Private Sub cmdAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAdd.Click Dim com As New OleDbCommand com.Connection = con com.CommandText = "insert into Watches values(" & txtWatchId.Text & ",'" & txtWatchBrand.Text & "','" & _ txtWatchModel.Text & "','" & txtManufacturer.Text & "'," & txtCountryOfOrigin.Text & "','" …

Your syntax should be: [code=sql] Insert Into Table (Col1, Col2, Col3) Select Col1, Col2, Col3 From SomeOtherTable [/code]

[code=c#] private void button1_Click(object sender, EventArgs e) { const string connStr = "Data Source=apex2006sql;Initial Catalog=Leather;Integrated Security=True;"; const string query = "Select * From Invoice Where InvNumber = @InvNumber"; using (DataTable dt = new DataTable()) { using (SqlConnection conn = new SqlConnection(connStr)) { conn.Open(); using (SqlCommand cmd = new SqlCommand(query, conn)) …

You can use INSERT() statements: [code=sql] IF OBJECT_ID('Customer', 'U') IS NOT NULL DROP TABLE Customer Create Table Customer ( CustomerId int identity(1000, 1) PRIMARY KEY, CustomerName varchar(50), Address1 varchar(50), City varchar(50), State varchar(2), Zip varchar(5) ) Insert Into Customer (CustomerName, Address1, City, State, Zip) Values ('Scott', 'Street 1', 'City 1', …

I don't understand what the question is or what you are trying to keep alive? You need to persist reminder information to disk some how with a database, configuration file, etc.

I believe by default the SMTP default service does not have any fields marked to log. I'm sure windows is smart enough not to write out the log file if you have not enabled any fields to be logged. View the attached screen shot

Please use code tags in the future. You're using 2 parameters in the query but only adding one to the command, the @Password variable is never used. See these threads for examples on using parameters: [url]http://www.daniweb.com/forums/thread191241.html[/url] [url]http://www.daniweb.com/forums/thread198304.html[/url] Here is an example of adding multiple parameters.

Don't use Regex, you're doing literal replacements not pattern replacements. Try: [code=c#] string Username = "Vuyiswa"; string Password = "secret"; string strBody = @"<p>Thank you for using !obooking System <br><br> Username:(Username)<br><br>Password:(Password)<br<br>Kind Regards !oBooking</p>"; strBody = strBody.Replace("(Username)", Username).Replace("(Password)", Password); [/code]

Please see thread [url]http://www.daniweb.com/forums/thread191241.html[/url] as you are having the same issue. Use parameters when you build your query. Building queries with string values is dangerous because the user could potentially escape the input and write raw TSQL, in addition it hurts performance. Do something like: [code=c#] private void simpleButton1_Click(object sender, …

What is a box character? [] is two characters and unix uses character 10 for a new line (\n), windows uses character 13 + character 10 for a line (\r\n).

This may be inside of a c# application but these are all questions related to MSSQL. In the future please post SQL question to the proper forum. 1. No work around as far as I know. Most people value data integrity and if a single operation fails they want the …

Use a mutex: MutexUt.pas: (Change 'LeatherPDF' to your application name) [code=delphi] unit MutexUt; interface uses Windows, Messages, SysUtils, Variants, Classes, Forms; function IsPrevInst: Boolean; procedure CheckPrevInstEx(MainFormClassName, MainFormCaption : String); implementation {---------------------------------------------} function IsPrevInst: Boolean; var semName, appClass: PChar; hSem : THandle; hWndMe : HWnd; appTitle: Array[0..MAX_PATH] of Char; begin // …

This is the wrong forum, please post future SQL questions to the MSSQL forum (or respective rdbms). Try a query like this: [code=sql] Update Asset Set Unit = Asset.Unit - ( Select Sum(Store.Quantity) From Store Where Store.ItemCode = Asset.ItemCode ) [/code] The above query will work for a 1-to-1 or …

Your connection string has a problem.. If you are using Integrated Security=True then you should not specify a user name and password. Also I think "uid=" is only valid for an MSSQL connection string if you are using the ODBC driver. I don't think it is valid for Native SQL …

Yes, it will. You can add it back between elements of the array though. [icode] string s = string.Format("{0}-{1}", array[0], array[1]);[/icode] or something like [code=c#] private void simpleButton1_Click(object sender, EventArgs e) { string[] array = new string[0]; string result = string.Empty; foreach (string s in array) { result += (string.IsNullOrEmpty(result) …

Double click on "My Project" in the solution explorer, select resources, and "Add Existing File". You can navigate to the file and embed it as a resource. Note -- You can use tools like resource hacker or resource thief (i forget the name) to extract the raw data file. It …

Paste the code for your generateRandomValue(); method. The problem is likely that when you have a break point that one second passes on your computers clock that changes the seed value for generateRandomValue(). You probably should use another GetRandomValue() method: [code=c#] private void simpleButton4_Click(object sender, EventArgs e) { List<int> lst …

What exactly is the problem? If you're writing an application to close other unwanted applications, why would you be executing a batch file? Please clarify what you are asking here..

What rdbms are you using?

Why write a script? You can probably hack the environment up enough... : [code=bash] #!/bin/bash export PS1="C:\\w> " alias dir="ls -l" alias del="rm" [/code] [code] sk@sk:/tmp$ echo "" >> l sk@sk:/tmp$ del l -bash: del: command not found sk@sk:/tmp$ . dos.sh C:/tmp> del l C:/tmp> [/code]

"this" refers to "this instance" of a class. You can use "this." to refer to properties and methods for the current class to help narrow down the intellisense menus as well as distinguishing between this.Method() and base.Method() if you are overriding a method from a base class. Here is an …

I don't understand what you're asking or how it relates to MSSQL. You're concerned with the programming languages over SQL so you might want to try another forum and ask a more specific question.

Try this: [code=c#] txtOutput.Text += " " txtNotesEntry.Text; [/code]

You consistently post in the wrong forum, this belongs in MSSQL. On top of that this question does not make any sense -- How do you configure a session before the session exists? Are you asking about ASP.NET session state integration with MSSQL, or the state of an SQL connection …

Your biggest problem here is that you're calling the function to concat a string in the same query as you're distincting() the records. Lets say you have 5 unique people in the list but a total of 90 records then the function should only run 5 times but in this …

[QUOTE=versatile36;890316]Whats the use of get and set in c# when we can add a property value like this [CODE]object.property="value"[/CODE][/QUOTE] The value is you encapsulate the field.

Check out the mail templates sample at Code Project. I believe it is done in C# but it can be easily ported over: [url]http://www.codeproject.com/KB/IP/mailtemplates.aspx[/url]

The assembly is referenced in your project references which can be managed using the IDE. As far as deciding to use which version, you need to compare them: [code=c#] private static VersionCompareResult CompareAppVerToDbVer() { using (DataTable dt = DatabaseSetup.GetSystemReg()) { if ((dt == null) || (dt.Rows.Count == 0)) { return …

You use https:// in C# whenever you are accessing an https:// website. I don't really know of another way to answer that question. SSL is handled under the hood for the most part by the framework so you don't have to worry about it. Here is an example of an …
