I'm pretty sure you can use PInvoke to do your DirectShow calls. There shouldn't be any reason to use C++ (un-managed code).

When somebody can't walk properly (possibly because they've had too much to drink), then they sometimes fall to all fours. This is how a crawler works.

Never heard of him. Not sure why you'd assume that anyone who read this would have his email, or know who he is. If he wrote an article, you can email him using the email he gave the site, via his article. If he posted here, you can email him via his posts.

You want to write code to do this, in C# ? If you just want to convert a file, your question has nothing to do with this forum, did you try google ?

How bizarre. You could not access your account, for hours ? I guess you didn't give a real email address to use to get your lost password then ?

Obviously, your limited account does not have permission to do this. Are you logging into the DB using a username/password, or windows integrated security ? If the latter, then changing your user could well change what the DB allows.

The error originates in the Access (JET) database, when it tries to modify (delete) data. Assuming your database doesn't use the strange security mechanisms available in Access (using SYSTEM.MDB and so on for user names and passwords), I would guess that either:
a) The regular user doesn't have modify permissions on the MDB file.
b) The regular user doesn't have modify permissions on the LDB file, or sufficient permissions to create one when it doesn't exist.
This would make the database readonly for non-administrators, meaning that all attempts to modify data will throw exceptions.
If possible, you should look at using SQL Server 2005 Express Edition instead (sqlexpress for short). The Access JET database engine has been living under threat of extinction for a decade or so by now and has a number of drawbacks (one of them being that no user can modify any data in the database unless they have sufficient permissions to actually delete the entire database file if they feel like it). The learning curve for shipping it with your app (making it install silently and getting your initial database installed) is kind of steep but the job is simple once you get a hang of it (and there are a lot of good articles on it).

Hi PeterTheSwede,
Thanks for your suggestion.I am agree with your point.

Hi,
I suggest you start here:
http://www.microsoft.com/sql/editions/express/default.mspx[^]
And... I was writing too fast. The old version (MSDE, based on SQL Server 2000) was a bit bitchy (command-line installer with a lot of options, tricky to invoke during your own install - especially tricky to detect failures). Entirely new scenario with the 2005 version (SQL Server Express). And to be honest, I've never integrated that into a setup (as I develop mainly custom apps, I usually install the software myself) - the SQL Server Express setup can be run interactively and is self-explanatory.
Also, you need to register to redistribute and I haven't gotten around to that...

If you have a strong named assembly and it is hacked using ILDASM and ILASM the application will fail strong name checking, but you can flag the assembly for skipping strong name validation. My question can you in the application code force the Dotnet framework to do a validation check and then take the necessary acton based on the result.
Thank you in advance

I want to capture keyboard input and display it in a textbox the same way that, in Excel when you type into a cell, your text appears in the box at the top. I've tried the following code with weird results. The problem is that the input string variable accumulates KeyChar input in odd ways. The correct input is parsed; it's just not displaying properly in textBox1. As you can see, I've tried everything I can think of to clear out both 'input' and textBox1 with no luck.
public partial class Form1 : Form<br />
{<br />
string input;<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
}<br />
void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)<br />
{<br />
dataGridView1.EditingControl.KeyPress += new KeyPressEventHandler(EditingControl_KeyPress);<br />
dataGridView1.EditingControl.KeyDown += new KeyEventHandler(EditingControl_KeyDown);<br />
e.Control.KeyPress += new KeyPressEventHandler(dataGridView1_KeyPress);<br />
}<br />
void EditingControl_KeyPress(object sender, KeyPressEventArgs e)<br />
{<br />
input += e.KeyChar.ToString();<br />
textBox1.Text = input;<br />
}<br />
private void dataGridView1_CellParsing(object sender, DataGridViewCellParsingEventArgs e)<br />
{<br />
input = String.Empty;<br />
textBox1.Text = input;<br />
textBox1.Text = e.Value.ToString();<br />
}<br />
}
