Hi guys,
I have a class named Configuration which is basically a collection of configItems.
Each config item has the following:
ID (allows persisting to file/database)
Name (a friendly way of searching for the item)
Value (self explanatory)
At present, ID is an integer type and both Name and Value members are string types.
However, the value may actually represent a boolean, integer, string, decimal and potentially other types.
The annoyance is currently having to cast the value to and from string to whaterver object type is required.
It would be great if the Value member could be the correct object type without having to cast each time.
I guess being able to have a generic member would be ideal but from my knowledge of generics, this doesn't appear possible.
How do you guys approach situations like this? What would you do?
Regards
Wayne Phipps

You could create a base class that contains just Id and Name, and create subclasses for each data type.
The base class could contain methods for getting data from each subclass. For example:
public int GetInt32() {
ConfigurationItemInt32 item = this as ConfigurationItemInt32;
if (item == null) {
throw new ApplicationException("Item is not an Int32 value.");
}
return item.Value;
}

I am writing to find out how I can escape special characters such as the (') when submitting information into a db using sql. The (') is causing my sql statement to break. Is there some kind of string function to search for these character's in a string and replace them? Please advise. Thanks.

You should be using paramatized queries and not directly using or concatenating user input to create a query otherwise your database is open to an sql injection attack.
You may find this article usefull:

Hope this helps

Not sure you're in the right forum - however replacing (') with ('') should work for you. ('') is the single quote twice not the double quote.

You are going to have to ask better than that. At least give people enough information so they could be able to attempt to help you.

Use the Directory.CreateDirectory method.

See: http://msdn2.microsoft.com/en-us/library/system.io.directory_members.aspx
Directory.CreateDirectory(INSERT_FOLDER_NAME_HERE);

Add it to the setup project in the same way as the first. This is easy if both applications are part of the same solution.

Hello Colin,
Thanx for the reply. I am not sure what you mean by that. Could you give some more detail about this or point me to a tutorial.
Thanx

I am creating a testing harness for my app and merrily loading assemblies using reflection into a seperate app domain.
What i was hoping to be able to do is unload the App Domain - releasing the file lock on the Assemblies. Allowing me to have write access to rebuild them in Visual Studio.
Unfortunately the app still has locks on the assemblies. Can anyone think of what i might be missing?
The code goes something like this:
1) Assembly assembly = reflectionDomain.Load(filename);
2) AppDomain.Unload(reflectionDomain);
Anyone any clues?
Cheers
Rich

There is a known issue with file locks when images are involved.
Image.FromFile(fileSpec) keeps fileSpec open; a work-around consists of a small
class that immediately copies the image to another image, and then disposes of the
original.
Maybe that's what you are experiencing...

How do you generate documentation from the C# file commented properly with a command-line compiler?
Thank you.

Take at look at the Sandcastle[^] project.
If you search here on code project, you will find that someone (I can't recall the name right now) has written a GUI for Sandcastle.

Hello gurus,
I'd like to know if it is possible to register CDOEXM.DLL and CDO.DLL from Exchange Server 2003 on Windows XP in order to compile a project that uses these libraries with Visual Studio 2005?
I wish to avoid programming in C# on a Windows Server with Exchange.
How can register these libraries on XP?
Thanks.
Fred.

I have a program that I want to write on a textarea before it goes thru the the loop, and for some reason it just hands there and write to the text area after it finished going thru the loop.
I tried putting a Thread.Sleep timeout of 5 seconds and it still doesn't display the text. How can I get it to display the text before it enters to the loop.
<br />
messageRTB.Text= "Running \r\n";<br />
messageRTB.Text += " Please Wait, this will take a while...";<br />
Thread.Sleep(5000);<br />
for (int i=1; i<=Num; i++)<br />
{<br />
}<br />

You are not allowing the user interface a chance to update the display. It only does this once it has finished processing your request. The request doesn't finish until it goes through the loop.
There is a way to get it to refresh the display, but I can't remember how off the top of my head.

Thanks alot, I didn't know there was a refresh method.
I solved the problem by using this.Refresh();
|
|
|
|
|
Calling the Refresh method does update the display, but the window remains unresponsive. If you want it to handle events (like moving the window, or redrawing it in case the user switched to another window while waiting), you should call the DoEvents method instead.
