Your best bet is to handle the paint event and draw a line on the form

Here's how:- Add a Label control to your form
- Set its "BorderStyle" property to Fixed3D
- Set its "Text" property to an empty string (or null)
- Clear the "Autosize" property
- Set the control's height (or width) to 2, depending on whether you want a horizontal or vertical line.

Actually, that doesn't render as well as a Label (see my earlier reply). If you look closely at the R edge, you'll see a few bad pixels.

You might consider, if you have the time, to write your own small custom line control. Then it will be painted exactly how you want with the styling that you want and it will not be messed up by any OS visual styles. However, it seems like most programmers suggest the label routine mentioned previously, I find that creating a new control adds your own custom touch to your applications.

My code is serializing a generic list of objects of class IOExtension. The IOExtension has two properties :
string Name
object Value
The serialization occurs without issue and provides the following XML:
<Culture>
<CodeCulture xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<GlobalExtensions>
<CultureItemOfIOExtension ID="" Type="MyNamespace.MyClass.IOExtension, MyNamespace.MyClass, Version=2.0.0.0, Culture=neutral, PublicKeyToken=03604d72884e7711">
<IOExtension>
<Name>GlobalExtensions</Name>
<Value xsi:type="xsd:string">GlobalValue</Value>
</IOExtension>
</CultureItemOfIOExtension>
</GlobalExtensions>
</CodeCulture>
</Culture>
This is all great, except when I go to deserialize the XML I get an exception on the Value property:
Namespace prefix 'xsd' is not defined.
Now I've done some testing and it appears that this does not occur when I serialize a single instance of the IOExtension object. This would appear to be an issue with serializing the generic list of objects but I'm not sure. I've thought about implementing System.Xml.Serialization.IXmlSerializable but I'm not sure how to go about serializing the object itself. Any suggestions or thoughts out there ?
I'm hoping that I can define the namespace manually somehow but obviously my knowledge of Xml Serialization is limited.

Your xmlns attributes MUST be on the root element.

Hey Leppie, thanks for the response. I tried your suggestion but, unfortunately the following Xml deserialied with the same error:

My delete button doesnt work.

foreach (GridViewRow row in GridView1.Rows)

int StaffID = Int32.Parse(GridView1.DataKeys[row.RowIndex].Value.ToString());
SqlCommand cmd = new SqlCommand("DELETE FROM Staff Where StaffID = '" + row.RowIndex + "'");
lb_msg.Text = "Record Deleted Successfully.";
GridView1.EditIndex = -1;
GridView1.DataBind();
}
}

I suggest you do some reading. I don't see any code here that actually calls your command, let alone associates it with a database. Is this the first time you've tried to write DB code ? There's tons of examples on the web, any example on how to use a SqlCommand will do.

}
I want to create Datatable sorted by Numbercurrent but error message Numbercurrent field not exist....

Hi All,
I'm using SQL Compact 3.5 and LINQ to use a local database in an application. I've automated a process to check that the database exists and is readable before letting the app continue, but I'm now stuck on the best way to implement some form of syncronisation making sure that the database is the right shape.
I'd like to have a class that is able to add or remove tables and columns basically ... a process to make sure that the database matches the context.
What is driving this is that future versions of my application may require amendments to the database and rather than having users go through the process of completely rebuilding the contents of the database it would be much better to have the database altered to match the new context included in the datalayer dll ...
Thanks in advance,
Jammer

This is going to be used strictly in 2D (on images to be specific) not 3D. I need to be able to divide the image until an end criteria is met using linear lines in any orientation (360 degree range). The internal nodes store the dividing lines, while the leaf nodes contain the average intensity of the region that the node is referring to.
My problem is that I dont know how to store a line segment that is on a specific place. Of course, i need to store the line as well as its location. The leaf nodes just contain a value that will be used to "color" in the region by a BSP tree decoder, but the problem is to store the dividing lines. Would the lines be stored as functions? if so how?
Some background info on BSP tree ftp://ftp.sgi.com/other/bspfaq/faq/bspfaq.html#6.txt[^]

Is it even possible to use an Olap database with an MDX query to retrieve data?
I am trying to do this with the Microsoft.Practices.EnterpriseLibrary.Data.Database object. My first problem begin when using the System.Data.Common.DbProviderFactories object and calling the function GetFactory("Microsoft.AnalysisServices.AdomdClient"). I am getting an exception saying "Unable to find the requested .Net Framework Data Provider. It may not be installed.".
I have installed SQLServer2005_ADOMD.msi so I should have this client installed right? Please help...

I'm designing a Windows App in C# that includes a task to execute the FC.exe application and capture its output. The problem is I can't seem to capture any of the output to display in one of my forms. This process works in a Console app but not in a Windows App. I use this same process for executing and capturing other applications output and it works just fine, but can't get it to work for FC.
Process process = new Process();
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.UseShellExecute = false;
process.StartInfo.FileName = "fc";
process.StartInfo.Arguments = @"C:\TonysTemp\TMT1.txt C:\TonysTemp\TMT2.txt";
process.Start();
StreamReader reader = process.StandardOutput;
process.WaitForExit(10000);
string line = reader.ReadToEnd();
process.Close();
I'm fairly new to programming and would appreciate any help.
Thanks

Hello,
VS 2008
Our client wants to have a phone dialer application. So they want to have different buttons with different shapes and colours. To make it look more like a telephone dialer. They don't want to have the normal button look that are dragged on to the form.
Is there any free third party controls that have the look and feel of different buttons.
Is it possible to create these buttons yourself? Any good links to be able to do this?
Many thanks,
Steve

You may create a custom button class that is inherited from the button class. Then define your own paint method and draw button the way you want. You should look into GDI stuff for colouring and speicall effects. There are may ariticles on CP.

In my windows form I am creating 1000 objects when a button is clicked and am not disposing those obects, just to check how much memory this act is taking through the Windows Task Manager.
What I want to know that, is there any way I could figure out which class instianting or taking more memory. I tried attaching my application with the windows CLR Profiler but it's hell like complicated and it shows me so many internal classes that I freak out and to be honest don't know which area to look into. Any best suggestion would help me. Thanks

Actually, Windows CLR Profiler is a really good free tool for this task, if not the best free tool.
What you basically do is the following:
- Start your app from CLR profiler
- Close your app
- In the summary window go to "allocation graph" (as an example)
- In the new window you can search for a specific method using the menu "Edit" -> "Find Routine". You could enter your button click handler here
- The graph will jump to the routine you searched for, in case the routine is found
- You can doubleclick on the rectangle representing your method to focus only on this method, and from your you'll have a better overview of the routine in question
hope this helps

Wow, never seen that CLR profiler before. That is a great tool. Thanks.
