Hi all,
I would like to know what is the difference between those 2 methods: Int32.Parse() and Convert.ToInt32().
Also, in your opinion, which method shall we use to convert a string to an integer and why?
Thanks,
Talal

I would use Int32.TryParse as it deals with strings that are poorly formatted ( are not just numbers )

Thanks for the info, I didn't know about this TryParse method

That works only in VS2005, not in VS2003.

You can also use TryParse on a double and set its options accordingly so that it parses only integers.

I always use Int32.Parse, because I can add also NumberStyles, for example if I want to parse a hexadecimal number.

The only difference when converting from a string is the way a null value is handled.
If you use Convert.ToInt32 on a string, it will return zero if the string is null, otherwise it will use Intr32.Parse to convert the string.

Hi All,
Is it possible <Without opening the file to display it to the users> to send a file directly to the printer to be printed as the user click on a print button instead of on the preview button? If it is would you know how to do so?
Thank you in advance.

I think you can do it, but not using ASP.NET. Probably something like ActiveX could help you, don't ask me how, I don't know Do some research on google.
heh, now I noticed that I'm not on ASP.NET forum, so if you are asking about WinForms, just ignore this post

Thank you, i have.
I found something called the printDialog, it's part of the .NET toolbox. I haven't played with it yet but it sounds promissing.
Thank you for your time.

I use this ...
this.printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);<br />
this.printDocument1.Print();
this assumes you have a printDocument1 of type PrintDocument defined
you also need a printDocument1_PrintPage function that uses System.Drawing.Printing.PrintPageEventArgs.Graphics to draw an image to the printer.
This just prints when it is called. there is no dialog to accept or cancel.
Sound confusing at first, but search for these strings in the MSDN library and it will help.
Hope this is what you were looking for.

Get rid of hte second static void main when you copy the classes across. That's the entry point, so remove one.

Hi, I want to change listbox backcolor into transparent or set a background image for it . how could i do? 
thanks

Probably you should read this one first:

There are no article about transparent listbox in internet.
Only for MFC.

hi all,in my application i need to store the word document(minimum 100kb of size) in to the database for searching the document content.I done it by using stream reader(ie:using stream reader i read the entire document and store it in to single column of the table)initially it works fine but now the number of records in the database is nearly 2000 and it take too much time to display the result.Is there any way to do this....

What result? You only describe the process you use to store the documents. You also have to descibe the process you use to create the result, or the only advice you will get is guesswork.

that is,the document i am storing in the database contain some informations about particular person when the user gives like "games" and click on search button it will search for the word "games" in all the word document that are present in the db(,if it present) then the entire detail of the all matched records will be displayed in the grid(like name,age,etc..).here i use the like query ie) "select * from tab.name where skill like games"

Exactly how do you store the decuments in the database? If you would store the documents as binary data, you wouldn't be able to search them like that.
How do you need to serach the information? Do you need a free text seach, or are you only going to search for specific keywords? If the later, then I would suggest that you extract the keywords when you create the record, and store the keywords in a separate table, so that you can make a much more efficient query.

This approach was obviously flawed from day one. You need to read your word docs to search them, your database is an extra overhead, and not the tool it should be. You need to store keywords with your word doc if you want efficient searching.

Hello,
I set the TypeConverter attribute of a class named MyFilter to typeof MyFilterConverter derived from TypeConverter.
[TypeConverter(typeof(MyFilterConverter))]
public class MyFilter
{
}
public class MyFilterConverter : TypeConverter
{
}
My executing assembly gets access to it by dynamically loading an assembly containing these 2 classes.
Eveything works fine as long as the executing and the dynamically loaded assembly are in the same directory. If this is not true the TypeConverter attribute will be ignored - easily proved by setting MyFilter as selected object in a property grid.
string fp = FILEPATH_FOR_DynamicLoad;
Assembly assembly = Assembly.LoadFrom(fp);
I would really appreciate if someone could help me out.
