If you catch the exception in Method2 and pretend that nothing is wrong, Method1 will be unaware of the error condition.
Re-throw the exception or throw a new exception in Method2, and handle that in the catch in Method1.
Alternatively (but this is sometimes frowned upon in object orientation) you can return a status from Method2 that tells Method1 if it succeeded or not.

Hi All,
I am using a c#.NET windows application,
is there any explicit method for comparing two folders according to their size and date modified?
Send Me any Related Link.Please it's Urgent
thanks

AFAIK the only way is to compare folder contents, a file at a time.

To compare the date modified you can simply use DirectoryInfo.LastWriteTime. To compare the size I am afraid you have to recursively go through directories and their subdirectories and sum up FileInfo.Length of contained files.

There may are some mistakes because i wrote it without much testing.
private long FolderSize = 0;<br />
<br />
private bool comparefolders(string path1, string path2)<br />
{<br />
string strdate_path1 = string.Empty;<br />
string strdate_path2 = string.Empty;<br />
long foldersize1 = 0;<br />
long foldersize2=0;<br />
bool folders_compare = false;<br />
try<br />
{<br />
DirectoryInfo dirinfo_path1 = new DirectoryInfo(path1);<br />
DirectoryInfo dirinfo_path2 = new DirectoryInfo(path2);<br />
if (dirinfo_path1.Exists == true && dirinfo_path2.Exists == true)<br />
{<br />
strdate_path1 = dirinfo_path1.CreationTime.ToString();<br />
strdate_path2 = dirinfo_path2.CreationTime.ToString();<br />
foldersize1 = GetFolderSize(path1);<br />
foldersize2 = GetFolderSize(path2);<br />
if (foldersize1 == foldersize2 && strdate_path1 == strdate_path2)<br />
{<br />
folders_compare = true;<br />
}<br />
}<br />
<br />
}<br />
catch (Exception ex)<br />
{<br />
string error = ex.Message;<br />
}<br />
return folders_compare;<br />
}<br />
<br />
private long GetFolderSize(string Root)<br />
{<br />
FolderSize = 0;<br />
SeekFiles(Root);<br />
return FolderSize;<br />
} <br />
<br />
private void SeekFiles(string Root)<br />
{<br />
string[] Files = System.IO.Directory.GetFiles(Root);<br />
string[] Folders = System.IO.Directory.GetDirectories(Root); <br />
FileInfo File;<br />
for(int i=0;i<Files.Length-1;i++)<br />
{<br />
File = new FileInfo(Files[i]);<br />
FolderSize += File.Length;<br />
}<br />
<br />
for(int i=0; i< Folders.Length-1; i++)<br />
{<br />
SeekFiles(Folders[i]);<br />

sir this is aravind here ,,i cant able to run the program,,if u can able to send full program(A-Z),,i am new to Dotnet,,,,,plz

Well, there are some additional considerations here:
- if you add a new file in one of the subdirectories, it does not change the last write time
of the top directory
- if you delete a file and create another with equal size, it does not alter total size.
So be careful about when you are satisfied nothing happened to a directory !
BTW: I am not sure about this, but the exact behavior could also depend on the underlying
file system (FAT, FAT32, NTFS, ...)

Thats right but he only wanted an method two compare the size and the modify date of the folder and not of the files in it.

I have 2 forms:
1- Main form viewing a datagrid of different values of database X
2- A secondary form used for adding new data into database X
When any data is entered in Form2 and Form2 is closed; it's needed to update datagrid with new values in Form1. But it doesn't update quickly, a 3-4 second late. Using Access database, I've found a nasty dirty solution : Having a timer and updating datagrid periodically. Is this a problem about Access slow query time or any problem about forms or etc? Any idea ???

Hi, I'm working on an open source IDE that has a built-in syntax highlighter.
Right now, whenever I want to remove text from the RichTextBox, I have to do this:
<br />
RTB.Text = RTB.Text.Remove(CharacterIndex, RemoveAmount);<br />
The problem is that changing RTB.Text erases all the Rich Text Format information generated by the syntax highlighter.
So my question is, how do I remove text from the textbox without resetting the RTF data?
|
|
|
|
|
It does work!
Just pay attention to any ArgumentOutOfRangeException that is thrown when either your CharacterIndex or your RemoveAmount is less than zero.

Hi,
I'm a intermediate java programmer and i just started learning C#.I would like to write an application that takes a txt file and send it to a fax machine. What is the best way I can do this? Thanks in advance ,any help would be gladly appreciated

As a former Java developer myself, welcome to the wonderful world of C#.
Regarding your question, have you looked at any of the articles on this site? This article[^], for example, talks about how to fax an image. It shouldn't be too hard to figure out from there.
Also note that all file-related APIs are nice and organized in System.IO namespace (a "namespace" is like Java's "package"). For example, to read all text from a file, you can simply go System.IO.File.ReadAllText("theFile.txt");

thanks for the quick reply Judah, I will take a look into that article.
|

I get the following error when I try to send the fax.
com object with clsid{d73733c8-cc80-11d0-b225-00c04fb6c2f5} is either not valid or not registered
How do I reference to the faxcom lib?
|
|
|
|
|
Eddy, sounds like you'll need the FaxCom faxing object installed. (At least, that article uses that component.)
Does this post[^] help?
|
|
|
|
|
Thanks a lot Judah you are very helpful.

I'm trying to get some custom control on my MasterPage to happen on the click event on my menu control based on a SiteMap. It's never hitting the MenuItemClick code. Any ideas?
In master page:
<asp:label id="lblTest" runat="server" text="Test">
<asp:sitemapdatasource id="ExampleSiteMapDS" runat="server" showstartingnode="false" sitemapprovider="mySiteMapProvider">
<asp:menu id="Menu2" runat="server" datasourceid="ExampleSiteMapDS" onmenuitemclick="Menu2_MenuItemClick">
In master page cs:
protected void Menu2_MenuItemClick(Object sender, MenuEventArgs e)
{
lblTest.Text = e.Item.ValuePath;
}
Thanks, Jessica
