hello all
what is the technique behind the implementing an option like recent files for a window application in c#....
the last 5 projects to be shown always and it must be open when user clicks for it... same as in Visual studio.NET

You write code so that you call each time you open a file. This code takes the filename of the file and you store the filename somewhere. When you display the menu that shows the last few files opened to retrieve the information you previously stored.
Where you store that information is up to you. You may decide an XML file works best, maybe in the registry, maybe a database (if you are already using one) or something else.

dude, i dont think its a good idea to write files info in registry. It will keep there even if you remove the app or you also need to code when uninstalling and so...

Hi,
some think otherwise, see e.g.
HKEY_CURRENT_USER\Software\Microsoft\MSDN\9.0\WebBrowser\MRU
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\File MRU
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\PowerPoint\File MRU
HKEY_CURRENT_USER\Software\Microsoft\VCExpress\9.0\FileMRUList
and where ever you put it, you will have to clean up upon removal.

mate, these softwares get remove but they dont remove their info from reg. thats why system startup keep slow even you uninstall the soft, isnt it ?

how to export Windows Registry information to .REG file using c#.net?
thanks in advance
|
|
|
|
|
You can write a bat file which export registry to reg file and call it from your program. Or you can just call reg.exe from your program directly.
|

For example I create a string variable as follows:
string strNumber = "123";
To convert it into integer data type which is better option and whats the differnce between these options.
a) Convert.ToInt32(strNumber);
b) int.Parse(strNumber);
Software Development & Web Development is my addiction. I am a Visual C# 2.0 and ASP.NET 2.0 Developer and working in Visual Studio 2005 using Dot Net Framework 2.0.

Hi,
The documentation is your friend!
The docs for Convert.ToInt32(string) state:
The return value is the result of invoking the Int32.Parse method on value.

Like Alan says - No difference.
The best option for converting from string to int though is the Int.TryParse() method. It returns false if the parse failed rather than throwing an exception like the other ways do.

More often than not, I've found that I need the exception thrown if only to avoid executing code that cannot proceed without a valid conversion.
I guess that means that you use the technique that best fits the situation/requirements.

All right all right  , use the method best suited and all that, depends what you are doing etc etc.... 
I just find I use TryParse followed by an if check much more often than Parse, but maybe that's just me.
Simon

The difference between using TryParse and Parse is that if you expect that it will fail (e.g. you are using it to validate and convert user input) then you should use TryParse. If you expect that it will always work then use Parse (e.g. you are parsing a value from an XML file where the schema says it is an integer).

I generally use this format for all the conversions, I never use Convert any more as I think it is just more lines of code than are necessary:
int num = 0;
string hold = "123";
if(!Int32.TryParse(hold, out num))
{
}
Keep It Simple Stupid! (KISS)

For this case yes, but be careful with the overload taking an object as the following will show you:
Convert.ToInt32(false) => 0
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - out now! ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

I generally avoid Convert.
|
|
|
|

if strNumber is null, Int23.Parse throws an exception while Convert.ToInt32 returns 0.

these days, I just know that chart control supported by Framework 3.5, it seems this control is very powerful!
before I am using Zedgraph code, now I think chart control can be used instead!! Am I true?
|
|
|
|
|
Well the charting control allows you do draw charts, and yes it is probably very similar to zedgraph. But only you can answer if it does everything exactly as you need it to do.

Can u tell me how to use Chart Control in C#.
|
|
|
|
|
You can get the docs here[^], and the samples here[^].
You need to learn yourself. If you get stuck come back and ask specific questions.
