That like it might work for what we used the third party tool for.
We basically have an online "application" (as in apply for service) that currently uses several ASP pages to stuff things into a database. The final step creates a PDF document by querying the database and filling in form fields from the queries. Creating XML from the database and filling it by hand would work just as well and would have saved us from buying a 3rd party library.
Do you happen to know if there is any way to protect/encrypt the XFDF so that it can't be edited in Acrobat (granted, the encryption's been broken before, but it's a little safer this way)?
I'll have to check this out for our next version.
I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf.

I am sure I am just not looking in the right place.
Can someone please point me in the direction of a good tutorial on using mock objects? I know what they are and why I need them, I just now need to know how to use them.
I am reading articles on unit testing here at CodeProject and Peter Provost's article touches on using mock objects, but the version of DotNetMock available for download as featured in the tutorial is different from what is in his article.
Marc Clifton mentions mock objects, but doesn't get into the guts of how to use them.
Where should I go from here?
Thanks,
- Craig

Just out of curiosity, I googled Peter Provost. The top of the list pointed to a log discussion where he stated he kept getting error no matter how he tried implementing DotNetMock and is relooking at the unit test issue.
I'm not sure what you are trying to do but building standalone test harnesses and running them against your objects prior to integration is pretty much standard fair. The typical approach we take is write a simple WinForm app with a 'Test It' button. It would then instantiate the object, pass data to it (usually what I provided as input to it), and displayed returned data (if applicable). It would be left without any exception catching so that if my object blew out of the water, I'd clearly see what I did to screw things up. If the harness is incorporated into the solution as an independant project, then I could also single step testing.

Hello, i made this click event for a form, which stores and then divides a name in 3 seperate vars i.e. John C Sharp, to "John", "C", "Sharp".
here's the code:
private void btnParse_Click(object sender, System.EventArgs e)<br />
{<br />
string strFullName;<br />
string strFirstName;<br />
string strInitial;<br />
string strLastName;<br />
int intLocation1;<br />
int intLocation2;<br />
int intLength;<br />
<br />
strFullName = txtName.Text;<br />
<br />
intLength = strFullName.Length;<br />
intLocation1 = strFullName.IndexOf(" ");<br />
intLocation2 = strFullName.IndexOf(" ", intLocation1 + 1);<br />
<br />
strFirstName = strFullName.Substring(0,intLocation1);<br />
strInitial = strFullName.Substring(intLocation1 + 1);<br />
strLastName = strFullName.Substring(intLocation2 + 1);<br />
<br />
lblFirstName.Text = strFirstName;<br />
lblInitial.Text = strInitial;<br />
lblLastName.Text = strLastName;<br />
}
and when i enter no text or when i tried to trigger the text change event of the TextBox i got this error (it works just fine when i enter a full name)
An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll<br />
<br />
Additional information: Length cannot be less than zero.
Thanks in advance (plz try to keep this simple as i am quite new to C#, thanks in advance  )

intLocation1 = strFullName.IndexOf(" ");
In an empty strFullName the " " isn't found, so intLocation1 is -1.
strFirstName = strFullName.Substring(0,intLocation1);
For an empty strFullName this means Substring(0, -1). What is a String with a negative length? 
You should catch empty and short names:
<br />
String[] nameParts = strFullName.Split(' ');<br />
if(nameParts.Length == 3){<br />
strFirstName = nameParts[0];<br />
strInitial = nameParts[1];<br />
strLastName = nameParts[2];<br />
else if(nameParts.Length == 2){<br />
strFirstName = nameParts[0];<br />
strLastName = nameParts[1]; <br />
}else{<br />
MessageBox.Show("Please enter a full name.");<br />
}<br />

Need some help :
When I tried to read Identity column with ADO.NET DataReader, I'm getting the following error::=>
"The data value could not be converted for reasons other than sign mismatch or data overflow.For example, the data was corrupted in the data store but the row was still retrievable."..
The Code which I wrote is described below:
oDR is data reader
while(oDR.Read())
{ListItem oItem = new ListItem(oDR.GetString(2),oDR.GetInt32(0).ToString());
wsdrpdwnlst1.Items.Add(oItem);} //wsdrpdwnlst1 is a list box
Note : (where oDR.GetInt32(0) supposed to give me the identity column.) but I am getting the above error. I need the help at the earliest if possible.

The error is definitely pointing at your oDR.GetInt32(0).ToString() portion of your code. You don't show what the SQL select statement looks like. But it sounds like the data you are getting is either not Int32 (and thus cannot convert it) or IS CORRUPT.
The first thing to do is find out just what the problem is with the data. Put a breakpoint at the while statement, step into the read, then do a QuickWatch on the oDR object to see what your second parameter data actually is. It could be something as simple as the fact that the data IS numeric, but your database is returning leading SPACES instead of leading ZERO.
If the data looks like crap, then the next thing to do is take the SQL that you are using in your program and run it inside Query Analyzer if is SQL or the equivalent if it is Oracle. See what you get back with the raw SQL and make sure your SELECT statement is truly executing the way you think it is.

Heyas,
I am writing on a component which uses the ProvideProperty Attribute to add new properties to other existing components. And it works fine. But, the new property doesn't have any description etc., in other words no Description, Editor etc. Attribute to make it fine. I am searching for hours now but didn't find any way to add Attributes to ProvideProperty-added properties .
Does anyone have experience in this?
Thanks,
'Mike

Maybe you are looking too hard. Take a look at this :
http://www.codeproject.com/dotnet/iextenderprovider.asp
All you have to do is this :
[Description("Description")]
[Category("Appearance")]
public string GetMyString(Panel p)
{
return EnsurePropertiesExists(p).MyString;
}
You set the description attribute not in the class, but on the actual GetXXXX function.

Ah, thanks very much!
This works. I already tried same as in the given code, but using the SetXXX method... well wrong choice >.<
Now it works perfect

Hi guys,
I've been searching for this for 4 hours, but it just doens't seem to work.
I have an access database, and i have to add a column to it.
Here's my code:
string connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +<br />
@"Data Source=D:\My Documents\Visual Studio 2003.NET\VerboServe\Verboserve.mdb;" +<br />
"User ID=Admin;" +<br />
"Password=";<br />
OleDbConnection conn = new OleDbConnection(connString);<br />
DataSet ds = new DataSet();<br />
<br />
conn.Open();<br />
<br />
OleDbDataAdapter dataAdapter = new OleDbDataAdapter("SELECT * FROM Verbs", conn);<br />
OleDbCommandBuilder commandBuilder = new OleDbCommandBuilder(dataAdapter);<br />
<br />
dataAdapter.Fill(ds, "Verbs");<br />
<br />
ds.Tables["Verbs"].Columns.Add("Wouter");<br />
<br />
foreach (DataRow thisRow in ds.Tables["Verbs"].Rows)<br />
{<br />
thisRow["Wouter"] = "True";<br />
}<br />
<br />
commandBuilder.QuotePrefix = "[";<br />
commandBuilder.QuoteSuffix = "]";<br />
<br />
ds.AcceptChanges();<br />
dataAdapter.Update(ds, "Verbs");
Can anyone tell me how to do this?
Thanks,
Wouter

ds.AcceptChanges is marking all rows as normal. DataAdapter.Update searches for changed rows and updates them, then internally calls AcceptChanges. Since you're doing this yourself BEFORE calling Update, the Update method is NOT seeing any changes.

Thankx for the info, but i am adding columns here, or is that the same?

You can't do it that way. You either have to issue an ALTER TABLE command or use a product-specific library to modify the database structure, like DDL for Access or SQL-DMO or SQL Server. This has been addressed many times before here. I suggest you click Search Comments and see some of the replies for more details and other ideas. While searching comments, you should probably also include the ADO.NET forum, too.

You should debug your code. An XML file is no different than a image file or an AVI - they are all just a stream of bytes. If your app treats them as such (And your code indicates that you do), then your app doesn't care - at the time of transfer - what is in the files themselves. XML files are not these special files sent from God, but just a formatted document, formatted accordingly to certain "guidelines" just like the various image codecs and AVI codecs.
The only problem I can see if your code is that you're writing out a binary file. Depending on how bytes are written or transfered, you may need to take file encodings into account. The only difference between the XML files you mention and the image and AVI files is that the former is a text file (ASCII, UTF8, Unicode, etc.) while the latter two are binary. There many be a problem in the way you handle text files. You should consider what FTP does, which is send such files using a text encoding while transfering.

how to build a generic application which will take a table as a parameter
& do add,modify, delete operations on that table can some one offer a solution please !
Dileepa

You can't take a table as a parameter. You could take a table name or a filename with a DataTable (serialized as XML) in it. Then use commands in the System.Data namespace (like System.Data.SqlClient.SqlCommand or System.Data.SqlClient.SqlDataAdapter) to do what you need. All the documentation is in the .NET SDK documentation and there are plenty of examples here on the CP site.

Handle the PrintDocument.PrintPage event and increment your printed page counter from 1 with each callback to your event handler.

Thanks Heath. Is that possible to find out number of page before printing?
Mazy
No sig. available now.

That depends on you - it's your code generating and printing pages after all. If you're simply printing text, you can get the height of the font, factor in the extra line height (which you control) and margins, and measure the string to print. From that you could calculate the number of pages. If you're drawing pictures and what-not, you calculate the picture size multiplied by any zoom amounts (percentages).
