Hi Dave,
IMO your remark is perfectly valid in general; however in this situation the form implementing the log functionality is assumed to be the main form, and to live for as long as the app is running. If not, one should consider implementing the log server in a separate class, or drop the statics.

Hi I'm currently trying to dynamicly invoke each class, in a namespace. So far I have managed to take one class and illiterate through it's methods, properties, etc.. and return a collection of data that gets added to a dataset. However the adjacent classes in that namespace I also need to invoke dynamicly,
So far i've attempted this with Reflection as I did with the individual class, but at a namespace leave it seams I need a different approach

hey all,
I created a shared addin project in visual studio 2005, an addin to excel that creates a button on the excel standard bar and assigns some event to it. Also, my addin acts an Automation addin. Now when I built the 'Setup project' of my addin, I got a setup file which I installed on a test machine. On this test machine, to my surprise, the addin's automation part is not working but the COM part is working fine i.e., the button is coming up on the standard bar.
The reason I found out for this is, the Programmable key word is not being added to the HKCR\CLSID\GUID\ of my addin in the test machine.
How to resolve this problem!? I want excel to recognise the UDFs i defined in my addin so that it also acts as an automation addin.
Regards.

The Font dropdown in the properties window should show all installed fonts.
It is possible to have font files in the Fonts Directory that have not been installed.
So firstly, make sure that the font you are looking for has been installed. (Open the Fonts Directory in Explorer and right-click, just in case you don't know.)

I have a list that consists of 'customer'-objects. Every 'customer' has a full name, address, email, and phone. Now I want to be able to do a search that lets the user type in information in a form and then perform a search based on the information the user typed in. In the form the user can type in 'first name', 'last name', 'address' and so on.
But how do I compare the information the user types in with the information stored in the 'customer' objects? If the user only types in the 'first name' and 'phone' for example the search must pick out all 'customers' that matches that.
Thanks for help!

So, you go through all your objects, and you match all with the same first name, and phone, if that's what they typed.

Maybe you can modify this a bit to suit your own needs. I am searching on one given string in a text box and pull all data in the DB to a listbox.
private void btnSearch_Click(object sender, EventArgs e)
{
FillListBox(textBox1.Text);
}
public void FillListBox(string searchValue)
{
try
{
dataTable.Clear();
DataAdapter =
new OleDbDataAdapter
("Select [PicId], [Path] From [Pics] WHERE PicId = '" +
searchValue + "'", conn);
DataAdapter.Fill(dataTable);
listBox1.DataSource = dataTable;
listBox1.DisplayMember = "Path";
listBox1.ValueMember = "Path";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
}
Excellence is doing ordinary things extraordinarily well.

Thanks for your replies.
I came up with a solution that worked well but I don't know if it's optimal:
I search through all the information stored in each customer in the list. If the information in the customer object matches the information the user typed in the textbox the result is stored in a new list. If the information in the search textbox is empty it's also seen as a match. See below:
public int[] SearchCustomers(Customer searchCustomer)
{
//Create list for search results.
searchResult = new List<Customer>();
//Loop through all information in the customer-objects.
searchResult = customers.FindAll(delegate(Customer C) { return SearchFirstName(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchLastName(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCity(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCountry(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchStreet(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchZip(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchCellPhone(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchHomePhone(C, searchCustomer); });
searchResult = searchResult.FindAll(delegate(Customer C) { return SearchEmail(C, searchCustomer); });
The final result is a list containing the matches of all search words.

Hi,
How can i compress and extract a folder programmatically?
Can i get any sample source code?

You can use J# for that, or you need a third party component.

hello
This scripts runs okay on SQL*Plus and TOAD (using same account "dev") but not sure when I try to wire it down through "System.Data.OracleClient" I keep getting the following error:
<br />
ORA-06550: line 1, column 8:\nPLS-00103: Encountered the symbol \"\" when expecting one of the following:\n\n begin function package pragma procedure subtype type use\n ... System.Data.OracleClient.OracleException...<br />
Here's the code:
<br />
DECLARE<br />

SELECT count(1) into count_item FROM user_sequences WHERE sequence_name = 'AUDITLOGSEQUENCE';<br />
IF count_item > 0 THEN<br />

END;<br />
As you can see, the script is anonymous block taking no argument
And I looked at the code, can't see anything wrong.
<br />
oCmd = oConn.CreateCommand();<br />
oCmd.CommandText = DBUtil.FixParameterNameForOracle(oContext.DefaultDBProvider, StringUtil.ReplaceSpecialTokens(SQL));<br />
oCmd.CommandType = System.Data.CommandType.Text;<br />
<br />
oDataSet = new DataSet(CmdFilePath);<br />
oTable = new DataTable(Name);<br />
oDataSet.Tables.Add(oTable);<br />
oAdapter = oFactory.CreateDataAdapter();<br />
<br />
oAdapter.SelectCommand = (DbCommand)oCmd;<br />
oAdapter.Fill(oDataSet, Name);<br />
oCmd is of type "System.Data.OracleClient.OracleCommand". And it takes no parameter or input argument. I googled a bit closest I found is this:
http://social.msdn.microsoft.com/Forums/en-US/adodotnetdataproviders/thread/579b5a98-ec74-4f6f-b5b4-6919d8bc3e7c/[^]
But my script contains no parameter.
Also, using "oCmd.ExecuteNonQuery()" instead of dataAdapter.Fill didn't help. I finally found one get around (NOT A DECENT SOLUTION!), that is to collapse the multiline script to single line!
<br />
DECLARE count_item int; BEGIN SELECT count(1) into count_item FROM user_sequences WHERE sequence_name = 'AUDITLOGSEQUENCE'; IF count_item > 0 THEN begin dbms_output.put_line('drop sequence AUDITLOGSEQUENCE'); EXECUTE IMMEDIATE ('DROP SEQUENCE AUDITLOGSEQUENCE'); end; ELSE dbms_output.put_line('no need to drop AUDITLOGSEQUENCE'); END IF; EXECUTE IMMEDIATE 'CREATE SEQUENCE AUDITLOGSEQUENCE MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20'; dbms_output.put_line('AUDITLOGSEQUENCE created'); SELECT count(1) into count_item FROM user_tables WHERE table_name = 'LOG'; IF count_item > 0 THEN begin dbms_output.put_line('drop table LOG'); EXECUTE IMMEDIATE ('DROP TABLE LOG'); end; ELSE dbms_output.put_line('no need to drop table LOG'); END IF; EXECUTE IMMEDIATE 'CREATE TABLE LOG (Id numeric(19,0) NOT NULL, CreateDate date default sysdate NOT NULL, Thread varchar (255) NOT NULL, LogLevel varchar (50) NOT NULL, Logger varchar (255) NOT NULL, Message varchar (4000) NOT NULL, InnerException varchar (2000) NULL,CONSTRAINT PK_LOG PRIMARY KEY (Id))'; dbms_output.put_line('table LOG created'); dbms_output.put_line('setup complete'); END;<br />
What the hell!? I have a big script next and I'm really not impressed ... any suggestion besides this?
Thanks

found it... I fixed strSQL from application, removing all instances of newline
strSQL = strSQL.Replace('\n', ' ');
I'm very impressed by the work on System.Data.OracleClient, some quality code!

I tried to list drives available in a system in checkedlistbox.When i click on the C:\ i want to list its files in a listview.I tried with the following but it does not work.Can you give me an alternative.<pre>
int p=checkedListBox1.SelectedIndex;
if(p==1)
{
try
{
reader = new XmlTextReader("path.xml");
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Text: //Display the text in each element.
// Console.WriteLine(reader.Value);
String s1;
s1 = reader.Value;
String ss;
ss = checkedListBox1.CheckedItems.ToString();
String sss = ss + s1;
object o3 = (object)sss;
DirectoryInfo dire = new DirectoryInfo(sss);
//DirectoryInfo[] dirs = dire.GetDirectories();
if (dire.Exists)
{
String[] folder;
folder = Directory.GetDirectories(sss);
foreach (string foldername in folder)
{
DirectoryInfo di = new DirectoryInfo(foldername);
if (di.Exists)
{
String[] files;
files = Directory.GetFiles(foldername, "*.exe*");
//FileInfo[] fi = dire.GetFiles();
foreach (String filename in files)
{
lvi = new ListViewItem();
lvi.Text = filename;
listView1.Items.Add(lvi);
}
this.Controls.Add(listView1);
}
}
}
break;
}
}
}
catch (System.Exception err)
{
MessageBox.Show("Error: " + err.Message);
}
}

Two things.
First you forgot to include the closing </pre> tag.
Secondly, what you are trying to do is sort-of like Windows Explorer so a quick google on 'explorer c#' reveals My Explorer In C#[^], as the first hit.
If that doesn't give you any ideas, google for yourself and have a look at some of the other hits.

Hi all,
I'm reading files from a certain folder and save everything into the database. I have a problem of reading multiple lines for a certain heading in a file and save them into one variable (to be saved into the database later).
e.g File content looks like this:
1. Date of Transaction :
20030728
2. Type of funds :
_Cash
3. Amount of Transaction(s) in Rand Value:
13500.00
4. Currency :
ZAR
PART H: List of available documents
Deal slip
Moneygram form
Copy of ID
BOP form
Gift declaration
I'm reading each line and save the value into a variable to be saved in the databse. e.g:
while ((line = reader.ReadLine()) != null)
{
if (line != null && line.Contains("1. Date of transaction :"))
{
line = reader.ReadLine();
DateOfTransaction = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("2. Type of funds :"))
{
line = reader.ReadLine();
TypeOfFunds = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("3. Amount of Transaction(s) in Rand Value:"))
{
line = reader.ReadLine();
AmountOfTransaction = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("4. Currency :"))
{
line = reader.ReadLine();
Currency = line;
line = reader.ReadLine();
}
if (line != null && line.Contains("PART H: List of available documents :"))
{
line = reader.ReadLine();
PartHListOfAvailableDocs = line;
line = reader.ReadLine();
}
}
Heading (PART H: List of available documents) from the file is having multiple lines underneath it. How do I read each line and save them all in variable 'PartHListOfAvailableDocs'.
I'd really appreciate your help in this regard.
Thanks.
