Does MySQL not support BLOBs (BinaryLargeObject) like the rest of the DBs?

First, use punctuation because I really can't underatnd what your trying to do.
Second, you can't store a NetworkStream object in a database. The underlying unmanaged resources will be lost when the NetworkStream object goes out of scope and your connection will be closed and torn down. Simply casting the object you retrieve from the database back to a NetworkStream object will not work.
What are you really trying to do with this?

Thanks for Reply my friend.
iam developing chat application server /client tools
i need when the user enter after signing in successfully to let my server store the networkstream object in the database instead of storing it in hashtable and then when i need to send him a message, I can retrieve the networkstream again from the database by his username and then write to its retrieved stream.
Yes my friend i used that idea to cast the object come from the database back to networkstream but it didn't work i don't know why my friend. like the below code
<br />
object retrievedstream = this.getstream();<br />
system.io.streamwriter mywriter = new system.io.streamwriter((networkstream)retrievedstream));<br />
mywriter.write("the message here");<br />
mywriter.flush();<br />
any help with that

I just got done telling you that you CAN'T do that and why.
If you're going to hold onto a NetworkStream, you MUST hold it in memory. You can't ship it off to a database and forget about it because the underlying unmanaged resource will not get saved to the database and will not be retained for later use in a reconstituted NetworkStream object.

i am trying to get all teh text content from a web page, (text only, no HTML)
so i am using this regex
<code>
private void ExtractPageContent(string HTMLString)
{
try
{
Regex regexObj = new Regex("<[^>]*>|\\\\n|(&\\w+;)|[0-9.,]|[;:,.'\"\\[\\]!@#$%^&*()-]\r\n");
string resultString = regexObj.Replace(HTMLString, "");
this.words = resultString.Split(' ');
}
catch (ArgumentException ex)
{
// Syntax error in the regular expression
}
}
</code>
but this is not giving me spaces between the words so i can then split on the space to populate a word array.
is there a way to acheive this while the regex is iterating the string ?
or am i taking th ewrong approach to this ?
kind regards,
g00fy

How do you define "text content". Any text between any html tags?
regards

yes, but i am also excluding the text between the 'a' tags
its a 'spider' bot program that crawls the net looking for words that meet certain criteria, then it looks them up in an online dictionary and maps the word to its meaning
so im just trying to get the words from the page then i do the criteria checks
i already have a regex to extract the href's
here is that one:
<code>
string href = Regex.Match(link, "href=\\\"(.*?)\\\"").Value;
</code>
only downside to that regex is it only gets 'legal' href's like href="fsdfs" not href=fsdfs but thats ok
regs,

thank you for that,
i did search though for about an hour, as i always do but i couldnt fine anything substantial, but my searches where for regex not for a complete solution
thank you again

keep a lookout for a dictionary builder article on here in a while,
funcitonality will (initially) include:
* recursively follow links from a starting URI, (to a limit)
* build dictionary based on words from the browsed pages, word and several meanings
* generate word files for MS Word and the like
* build thesarus from generated dictionary
* merged dictionary database table to recursivley build bigger dictioanry with meaning comparisons
* multilingual translations, for word and meaning
* run from desktop client or login to web frontend
* print a formatted dictionary by word prefix
all this will hopefully be achieved using online dictionaries and translators that are already in place.
also, does anyone know how MS query string looks like for searching clip art from within office, i have a clip art library builder, using similar concept and i would like to access the clipart from microsoft. im not sure they do licence checking on there clipart as you can search them from thier webpage. perhaps i will start another thread on this soon

Hy,
I'm trying to create a class which sends files (common file formats - xls, pdf, txt, jpg) to
a specified printer and a specified paper slot.
My problems are:
- Doing it with Process.Start (verb "print" or "printto") is a good and quick method,
but i have to set the paper slot for each document. (Is there another possibility?)
- The function should be dynamic for all file types, that means, I do not want to make a class
for every file type (PDFDocument, TXTDocument etc...)
The best solution for me would be a function like this:
public void PrintFile(string FileName, string PrinterName, string PaperSlot)
{
...
}
Maybe there's a component or something else which is solving my problem. I'm already sick of searching...
I'm thankful for every answer.
Greez && Thx

Hello,
When l got to update my database l get this error message "Missing the datacolumn 'DepartmentName' in the DataTable 'Employee' for the sourceColumn 'DepartmentName' ".
I have a database application. 2 tables. Department and Employee.
Department -> DepartmentCode (PK)
DepartmentName
Employee -> EmployeeID (PK)
Name
Surname
DepartmentCode (FK)
I have create this relationship in code using relationships in the form load event. see below:
<br />
private void frmEmployees_Load(object sender, System.EventArgs e)<br />
{<br />
try<br />
{<br />
cnn.Open();<br />
OleDbCommand cmd = cnn.CreateCommand();<br />
cmd.CommandType = CommandType.Text;<br />
cmd.CommandText = "SELECT * FROM Employee";<br />
da.SelectCommand = cmd;<br />
da.FillSchema(ds,SchemaType.Source,"Employee");<br />
da.Fill(ds,"Employee");<br />
<br />
cmd.CommandText = "SELECT * FROM Department";<br />
da.SelectCommand = cmd;<br />
da.FillSchema(ds,SchemaType.Source,"Department");<br />
da.Fill(ds,"Department");<br />
<br />
DataColumn parentColumn = ds.Tables["Department"].Columns["DepartmentCode"];<br />
DataColumn childColumn = ds.Tables["Employee"].Columns["DepartmentCode"];<br />
<br />
ds.Relations.Clear();<br />
drEmployees = new DataRelation("EmployeeDetails",parentColumn,childColumn);<br />
ds.Relations.Add(drEmployees);<br />
<br />
txtEmployeeID.Text = ds.Tables["Employee"].Rows[0]["EmployeeNumber"].ToString();<br />
txtFirstName.Text = ds.Tables["Employee"].Rows[0]["FirstName"].ToString();<br />
txtSurname.Text = ds.Tables["Employee"].Rows[0]["Surname"].ToString();<br />
txtDateOfBirth.Text = ds.Tables["Employee"].Rows[0]["DateOfBirth"].ToString();<br />
txtAddress1.Text = ds.Tables["Employee"].Rows[0]["Address1"].ToString();<br />
txtAddress2.Text = ds.Tables["Employee"].Rows[0]["Address2"].ToString();<br />
cboDepartment.Text = ds.Tables["Employee"].Rows[0]["DepartmentCode"].ToString();<br />
<br />
string departmentCode = ds.Tables["Employee"].Rows[0]["DepartmentCode"].ToString();<br />
DataRow[] departmentRow = ds.Tables["Department"].Select("DepartmentCode = '" + departmentCode + "' ");<br />
string departmentName = departmentRow[0]["DepartmentName"].ToString();<br />
<br />
<br />
this.UpdateDepartments();
} <br />
catch ( OleDbException ex )<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
catch ( Exception ex )<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
}<br />
When l click the update button, l run this code and get an error on the update.
<br />
ds.Tables["Employee"].Rows[0]["FirstName"] = txtFirstName.Text;<br />
ds.Tables["Employee"].Rows[0]["Surname"] = txtSurname.Text;<br />
ds.Tables["Employee"].Rows[0]["DepartmentCode"] = departmentCode;<br />
<br />
da.Update(ds,"Employee");
I hope someone can help me with this question. very important.
Thanks in advance,
Steve

how do i populate a treeview with data from the dataset.
i dont want to populate it by writing an xml file n then populating...
just refreh the treeview everytime i enter the details in the database..how to do it?
|
|
|
|
|
Well... If I understand this correct. You have a SQL Server that can be updated with data, and a exe that sould update its treeview when something has happend in the database?
I assume your using a MS SQL server of some flaour. I would have made a insert/update trigger in the database that executes a "extended stored procedure" written in C++. The extended stored procedure could contact your application over Eg. a socket connection, pinging the exe to do a refresh against the SQL Server. 
If your using MS SQL Server 2005 beta2 I'm sure you can make use of the .NET framework and do something cool with Remoting.NET from the SQL server to your app.
