I have VS 05 and C#. But, every time I publish something and send it in an eMail, it ALWAYS says the program is missing files, so I thinksit's in the publishing.

What are you emailing - the link to the published .application file? That's what you should email.
Can you give us the exact error message? We can better help you then.

I tr to eMail the entire program. Say you attach a file to an eMail. I attach the program. When they get the eMail, it syas certain vital files are missing.

You should zip up all your application files -- go to the folder where your source code is, go in to the bin\debug directory, and zip up all the files there. Email that zip file.

Hi,
Does anyone know if it's possible to trigger an event whenever a video frame is being refreshed (e.g., every 50 ms for a 20 fps frame rate)? It can be either with DirectX or WMP SDK (or anything else within .NET. Alternatively, I could poll the video player and ask which frame is being played. Can't do that either at this point.
Thank you,
Yigal Agam

I'm not sure if this is the right forum to post this in, but I'm not sure where it fits.
My company distributes some reference books on CD-ROM using 3rd party software called Folio Views. The actual content stays on the CD, but what is called a shadow file gets installed on the user's drive. The shadow file allows the user to highlight and annotate the text with out modifying the actual content (the shadow file acts like an overlay). Because of this the shadow file needs to be modifiable by the user. On Vista, the software gets installed as administrator (after UAC click), but when the user launches the software it loads with the users permissions so they can't write to the shadow file and the load fails. I'm using the setup project built into Visual Studio 2005 right now, but we may buy InstallShield if its better, for this and I can't find an option to set permissions on the files. Is there a custom action I can assign to make the file writable by the "users" group?
Thanks.

You could fiddle with the permissions in a custom action, yes. This isn't really addressing the root cause of the problem, which is that your shadow file is in the wrong place. I'm guessing you've stuck it in the program files directory - it really should be in the user's profile, under application data, or Documents.
|
|
|
|
|
Yeah, unfortunately I have to work within the bounds of some third party software and there isn't a way to automatically generate a new shadow file for each user so I need to do it this way. Do you know what the command should be in the custom action?
|
|
|
|
|
Ah well if you add a custom action, then you should be able to use the System.IO.File.GetAccessControl(name); to get a FileSecurity object, and then use fsec.AddAccessRule(new FileSystemAccessRule(...));

What I need to do is append the string " + \" to the last line of a file and then go to the next line and write a string. It would seem something like this should work.
Texg.Write(" + \\");
Texg.Write("\n");
Texg.Write("New Text String");
I get this as output where the @ sign is a rectangle:
+ \ @ A Text String + \@ A Text String + \@ A Text String
What I want is:
+ \
A Text String + \
A Text String + \
A Text String
This is easy in C++ and I am sure I missing something obvious.

Try
Texg.Write(" + \\");
Texg.WriteLine("New Text String");
or
Texg.Write(" + \\");
Texg.Write("\r\n");
Texg.Write("New Text String");
|
|
|
|
|
try:
Texg.Write(@" + \");
Texg.Write(Environment.NewLine);
Texg.Write(@"New Text String");

Well - that's a weird cross post.

When I click on Create a Folder Button as below I get an error-Object reference not set to an instance of an object. How should I get rid of this error-Object reference not set to an instance of an object
private void btnCreate_Click(object sender, EventArgs e)
{
try
{
if (tvFavorites.SelectedNode.Tag == null)
{
OleDbCommand insertfolder = new OleDbCommand("insert into favFolders (folder_name,folder_parent) values('" + txtFolderName.Text + "'," + tvFavorites.SelectedNode.Name + ") ", dbProfiles);
if (dbProfiles.State == ConnectionState.Closed)
dbProfiles.Open();
insertfolder.ExecuteNonQuery();
string folder_id = "";
insertfolder.CommandText = "select max(folder_id) from favFolders";
folder_id = insertfolder.ExecuteScalar().ToString();
dbProfiles.Close();
TreeNode tn = new TreeNode();
tn.Name = folder_id;
tn.Text = txtFolderName.Text;
tvFavorites.Nodes.Add(tn);
}
else
{
OleDbCommand insertfolder = new OleDbCommand("insert into favFolders (folder_name,folder_parent) values('" + txtFolderName.Text + "'," + tvFavorites.SelectedNode.Parent.Name + ") ", dbProfiles);
if (dbProfiles.State == ConnectionState.Closed)
dbProfiles.Open();
insertfolder.ExecuteNonQuery();
string folder_id = "";
insertfolder.CommandText = "select max(folder_id) from favFolders";
folder_id = insertfolder.ExecuteScalar().ToString();
dbProfiles.Close();
TreeNode tn = new TreeNode();
tn.Name = folder_id;
tn.Text = txtFolderName.Text;
tvFavorites.Nodes.Add(tn);
}
txtFolderName.Text = "";
lblFolderName.Visible = false;
txtFolderName.Visible = false;
btnCreate.Visible = false;
btnCancel.Visible = false;
}
catch (Exception ex)
{
func.ErrorReporter(ex, "008010");
//This line opens the specified file or creates it if it does not exist
//Note that you must use a double slash in the string instead
System.IO.FileStream myLog = new System.IO.FileStream("C:\\myFile.txt", System.IO.FileMode.Open);
//Creates the new TraceListener that specifies myLog as the target for the output
TextWriterTraceListener myListener = new TextWriterTraceListener("C:\\myFile.txt");
//Adds myListener to the Listeners collection
Trace.Listeners.Add(myListener);
Trace.Write("Object reference not set to an instance of an object");
Trace.Flush();
}
}

Somewhere in your code you are attempting to work with an object reference that does not point to an actual object.
You should step through your code using the debugger to identify which object reference is causing the problem.

Thanks for your reply. But I want to know this process of Stepping through the code. Can you please guide me. When I clicked on Debug pulldown menu and clicked on Step Into the application starts to run. What are the next steps I need to take?

Hunt for that cunningly hidden breakpoint option and set it. It's fantastically easy to do with this.

Yes, Actually what I want to do is to see on what line I am getting the error. And can you please guide me through that cunningly hidden breakpoint??
