[QUOTE=Dumbledor;1222727]4 students just copied this code and lost all their points for the assignment.[/QUOTE] Out of curiosity... which school did this happen at?

Out of curiosity have you read the WCF/WPF Chatter codeproject article? [url]http://www.codeproject.com/KB/WCF/WCFWPFChat.aspx[/url] You could use WCF to generate proxy clients that will handle threading for you by applying attributes on the contract implementation. There is also a "workaround" for using shared assemblies (instead of proxies) and having .NET handle the …

You can also use the configuration file of the assembly to store the value for each local user on the machine which sounds like it would be the most fitting in this case. Add a property called "CheckedItems" as a string to your Settings.Settings file and wire up these events …

To expand on adataposts answer: [code] private void button1_Click(object sender, EventArgs e) { int iYear; string sModel; if (!int.TryParse(textBox1.Text, out iYear)) { MessageBox.Show("The year must be numeric"); return; } if ((iYear < 1950) || (iYear > DateTime.Today.Year)) { MessageBox.Show("Invalid year, grandpa."); return; } sModel = textBox2.Text.Trim(); if (string.IsNullOrEmpty(sModel)) { MessageBox.Show("Model …

SQL Server has a different type of GUID compared to what you would generate normally in C#. Take a look at this article: [url]http://sqlblogcasts.com/blogs/martinbell/archive/2009/05/25/GUID-Ordering-in-SQL-Server.aspx[/url] If you're using a GUID primary key identifiers in a heavily upserted table it may behoove you to read that article.

You need to read about [icode]IDisposable[/icode]. You were leaking objects that implemented IDisposable and had unmanaged resources. When you call [icode]GC.Collect()[/icode] and unreferenced objects are detected with finalizers then the finalizer *should* be invoked but the object will not be destroyed until the finalizer has ran, pushing it back another …

I posted a code snippet some time ago that uses encrypted passwords: [url]http://www.daniweb.com/code/post969838.html[/url] MD5 is a checksum so you can't "reverse" the hash to arrive back at the original password. This is usually the preferred method of storing passwords. In my example I used reversible encryption.

Can you post the table structure? Here is an example of what may cause this: [code] select Cast((59670.0 / 100.0) as decimal(2,2)) [/code] Results in: [code] [COLOR="Red"]Msg 8115, Level 16, State 8, Line 1 Arithmetic overflow error converting numeric to data type numeric.[/COLOR] [/code] It appears you're using a number …

[B]>> the problem is that i cannot find have to fill the datacolumns with the value of the datareader.[/B] I don't understand what you're trying to do. If you are only using a single table then consider using a [icode]DataTable[/icode] over a DataSet. Regarding the data reader -- are you …

You could use a dictionary to index the controls. [code] using System; using System.Collections.Generic; using System.Windows.Forms; namespace daniweb { public partial class frmAutoPopulate : Form { Dictionary<Control, string> bindings; public frmAutoPopulate() { InitializeComponent(); } private void frmAutoPopulate_Load(object sender, EventArgs e) { bindings = new Dictionary<Control, string>(); bindings.Add(textBox1, "Name"); bindings.Add(textBox2, "Adddress"); …

Why not create the search results in a database and cache the results for the life of the session? If your source data is updated then you can invalidate the current cache and regenerate it. I'm still not clear on what your problem is exactly though. Could you explain it …

Parsing string representations of dates can often lead to problems. [URL="http://msdn.microsoft.com/en-us/library/1k1skd40.aspx"]DateTime.Parse()[/URL]: [QUOTE] ...

[QUOTE=finito;1220962]Well The Insert Statement in SQL would look like Insert INTO TABLE1 (FIRST_NAME) VALUES ('" + textbox2.text + "') did you connect your database and fill your dataset?[/QUOTE] You should always use parameterized queries.

[B]>>Is there a SQL Server 2003???[/B] No. Please start new threads for new questions. You will find your questions get answered more often that way!

You can just use [icode]Process.Start()[/icode]: [code] private void button1_Click(object sender, EventArgs e) { using (System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo() { ErrorDialog = true, ErrorDialogParentHandle = this.Handle, UseShellExecute = true, FileName = @"http://www.apexsoftware.com" })) { }; } [/code]

I borrowed the steps from another forum: Ø Create an Uninstall.bat file containing: C:\WINDOWS\system32\MsiExec.exe /I{productcode} (Path depends of your Windows version, check where your system32 folder is located.. you can also use %systemroot%\System32\msiexec.exe) (You’ll find the productcode in Visual Studio.NET > Tab Properties in the setup project you’ve just created) …

Look at this line: [icode]for (int i = 0; i < photo.Count; ++ i)[/icode] It should likely be [icode]i++[/icode] as everything I can think of in the CLR uses 0-based indexes. In the code you provided your first iteration would start at "1" then end at (photo.Count+1) giving you an …

What I find easier, but by no means proper, is to load a numerical column associated with the belt rank. You can hide the column and when the user wants to sort on belt you would really sort (under the hood) on the numeric column. You have to jump through …

Upload your solution. I don't have any idea what could cause this off hand but there is a lot of designer generated code in datasets. You need to find out where exactly the null reference is... and to do that you need to step through the dataset. Pop in to …

Great post apegram. I'm more of a concrete entities person but LINQ would probably be the better way to go for this task (and a lot less code!) You could also do it this way [code] [XmlRoot("employees")] public class EmployeeList : List<Employee> { public EmployeeList() { } } [XmlType(TypeName="employee")] public …

It may be a long shot but the card could be bad. Next time this happens try powering down your computer and disconnecting power, then reconnect it. This may be what inadvertently fixed the issue when you installed a second NIC. I have had motherboard problems before that would only …

You can't use reverse DNS to determine a website visited. A single IP address can host multiple websites and may not have a reverse DNS entry. When you visit a website your browser resolves the IP address of the host in your address bar then sends a GET request with …

Please post ASP.NET questions in the ASP.NET forum. You can make a call to [icode]Session.Abandon()[/icode] to terminate the current session. [url]http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate.abandon.aspx[/url]

Well I disagree. If you take a look at MSDN or experts exchange they both mark the response answering the OP. When that has been marked as the answer it also shows directly beneath the original question so you don't have to sift through other (possible unrelated) posts. Once you …

If you have locate/slocate/mlocate installed you could [icode]locate httpd.conf; locate apache.conf[/icode]. You could also use [icode]find[/icode]: [code] find /etc -type f \( -iname httpd\.conf -o -iname apache\.conf \) [/code]

Install the drivers for your network card. If you go to start -- control panel -- system -- hardware -- device manager you should see a yellow icon in the hardware. Thats likely your NIC.

To require administrative rights you need to embed and application manifest file. You can do this by "File -- New -- ... -- Application Manifest File".

Update the field in your data source instead of the [icode].Text[/icode] value, or update both. Also in your save methods have it call something like [icode]buttonSave.Focus()[/icode]. I believe until a control loses focus (by default) it does not perform validation and update the underlying values in the databound source.

You're killing me with the [URL="http://www.acronymfinder.com/"]acronyms[/URL] :P! You should at least say the full name once before dropping [icode]CEICW[/icode]. I have never heard of that until I read this thread. Anyway back to your question. When you click links inside of OWA does the page immediately fail or does it …

[code] a = b + c \ +d; printf("\n"); [/code] Technically those are all three "lines" but you're using the "\" to have the script interpret them as though they are one line. What you could do is match all of the 's, then exclude all of the lines with …

You can authenticate users from a database, INI file, text file, remote database, XML file, CSV file, or just about anything else you can come up with. I personally use a database and that is also what I advocate so I would stick with the concepts you use in your …

using [icode]Application.DoEvents();[/icode] is NOT a good idea. Use another thread or force screen updating (like the original code snippet) but don't process messages with [icode]DoEvents()[/icode] in the middle of a long-running code block.
