I have a "test.cmh" help file that I compiled. Is there a way to restrict the use of the help file to be used only via an C# applications?. in other words, the CHM file will not run when user click on it.

Simply: No I don't think so unless you want to embed the help file as a resource and then extract it when you need but I'm not sure that this will work.
Another simple protection method would be to give it a different name without the .chm extension, for general users they wouldn't change the extension, but then again they probably wouldn't look for it.

I was working on a project for a client who runs a scheduled backup daily. He needs to stop the SQL service, which I have done successfully, but I need to find a way to access a tape drive to see that the tape is actually inserted. I do not know of any way to do this with ntbackup.
I have tried to find this on the web but came up fruitless.
This is a windows form in C#, using .NET Framework 2.0.
The tape drive does not come up in the DriveInfo.GetDrives().
Does anybody know how I can verify that the tape is inserted in C# 
Thank you in advance!

Hi everyone,
I have just began to create applications for Pocket PC, and I'm trying to add clipboard functionality. Unfortunatly the normal code doesn't work for some reason, for example:
Clipboard.SetDataObject(textBox.Text,true);
This works in a normal Win32 application, but when I try to use it in a Pocket PC application it produces this error:
The type or namespace name 'Clipboard' could not be found (are you missing a using directive or an assembly reference?)
Could someone point me in the right direction on how to solve this?
Thanks for any help,
From Daniel

Hello,
I have a problem with the progressbar in the following code:
FtpClient ftp = new FtpClient("ftpadres", "user", "password",ttl,21);
try
{
ftp.Login();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
ftp.ChangeDir("vrbo");
string fullPath = txtLoggedInSource.Text;
string[] dir = fullPath.Split(new Char[] { '\\' });
int length = dir.Length;
string directory = dir[length - 1];
ftp.MakeDir(bedrijfid + "_" + directory + "_" + timestamp);
ftp.ChangeDir(bedrijfid + "_" + directory + "_" + timestamp);
DirectoryInfo dir2 = new DirectoryInfo(txtLoggedInSource.Text);
FileInfo[] files = dir2.GetFiles();
int filecount = files.Length;
pbStatus.TabIndex = 0;
pbStatus.Maximum = filecount;
pbStatus.Minimum = 1;
pbStatus.Step = 1;
/* THIS WORKS PERFECT !!!
for (int i = pbStatus.Minimum; i <= pbStatus.Maximum; i++)
{
pbStatus.PerformStep();
}
* */
// HERE THE PROGRESSBAR DOESNT MOVE
foreach (FileInfo f in files)
{
ftp.Upload(txtLoggedInSource.Text + "\\" + f.Name);
pbStatus.PerformStep();
}
label1.Text = "All files are upload successfully";
ftp.Close();
Can someone please help me why it doesn't work with upload
Thx

Standard question #1:
What do you mean by "not working"?

b { font-weight: normal; }

You're not giving the form a chance to update itself. See if this works:
foreach (FileInfo f in files) {
ftp.Upload (txtLoggedInSource.Text + "\\" + f.Name);
pbStatus.PerformStep();
Application.DoEvents();
}

You mean
Application.DoEvents(); no?

Me and my partner are doing our final year project in Addis Ababa University.
The problem here is eventhough we are using one of the latest voice modems we can not have a live communication up on connecting calls. We have a demo C# code which can record calls (that worked).I donot think it is the code's problem but I wish if you guys out there help me use my voice modem for live connection.

How can I export a Ms Word file to text?
I need it badly! pleasssssse help me soon as possible.

hi Sahar
Try this code. I actually found an article from C-Sharp Corner on how to open up a word file in C#. You just have a look on that article, I added to the code a little to meet ur requirement.
//Create Word Application class.
Word.ApplicationClass app = new Word.ApplicationClass();
//file which you need to convert to text file
object fileName = @"Sample.doc";
//to set the source file readonly.
object readOnly = true;
object missing = Type.Missing;
//to make the document visible.
object visible = true;
app.Visible = true;
app.Documents.Open(ref fileName,ref missing,ref readOnly,ref missing,
ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,
ref missing,ref visible,ref missing,ref missing,ref missing,ref missing);
//select the whole text in Word file
app.Selection.SetRange(0,app.Selection.StoryLength);
//get the selected text, the whole word file content.
string text = app.Selection.Text;
//create StreamWriter Object.
System.IO.StreamWriter writer = new System.IO.StreamWriter("YourTextFile.txt");
//split the text in to lines.
string []lines = text.Split(Environment.NewLine.ToCharArray());
//Iterate over each lines and write to file.
foreach(string s in lines)
{
//write a line to file.
writer.WriteLine(s);
}
writer.Flush();
writer.Close();
My small attempt...

I ran into a similar problem a while back. Do you have the crystal reports prerequsite checked?
If not, do this:
1. Go to solution explorer.
2. Right click on your setup project and hit properties.
3. A form should popup with the projects properties, find the button that says: Prerequsites.
4. From the list that appears check: Crystal Reports for .Net Framework 2.0.
Build the setup project and your done!
Now if you go to the setup folder in your project directory, you will see that it has added the necessary components to get crystal reports working on the target machine.
Hope that helps

Hi,
I have a form on which there is a textbox and a datagrid. Both the text box and datagrid are bound to some data sources. There are only two columns in the datagrid. The text box basically displays a column of the datagrid. When the user clicks on the New or Modify button, he is able to edit the value in the text box or add a new one which is added to the bound grid. But the problem is that the Text property of the text box becomes equal to empty string before it is added to the database or the grid. I have checked the source code many time but i dont know why it happens. I have faced the same problem previously but at that time, it became equal to empty string when AcceptChanges() method of the datatable was called. Any kind of help or suggestion please...
Regards,
Wasif Ehsan.

Put a Chatroom in your site easily and free!
Doesn't requiere other apps runing on server. Very simple to implement.
It uses the same ISS as the chat server so you don't need to run other apps. The client is your web browser. Very easy to implement and to expand to build on. And free!:

Nice idea, just a pity it locks up IE... and with free, does it include full source too? If so, why not post an article?

is there a way to utilize media encoder and make a new video comprised from segments of the same video - encoder should run 'behind the scenes. i'm having trouble loading the profile for encoder as well as getting encoder to accept a session... thanks

I'm developing software for a class that takes a video and records instances of that video using time stamps. I was wondering how to create individule files of those instances from those time stamps. thanks.

Background:
I have Access 2003 installedand the database I'm trying to connect to via C# was probably created using Access 97. I don't have the option to upgrade the database and must remain in Access 97 format. The database is protected by a workgroup ID. The command line option for spawning the database is:
MSACCESS.EXE c:\master.mdb /wrkgrp c:\master.mdw /user foo /pwd bar
This brings up the database, but I get an error stating:
You can't make changes to the database objects in the database 'master.' This database was created in an eariler version of Microsoft Office Access....
Problem 1: Read-only connection
If I try and connect to this database from c#, I get the following error.
System.Data.OleDb.OleDBException: Cannot start your application. The workgroup information file is missing or opened exclusively by another user.
Since I can open the database using the command line above, I suspect in order to read the database, I need to somehow specify read-only access within the connection string. Here's my connection string:
String conStr =
"PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\master.mdb;SystemDB=C:\\master.mdw;User Id=foo;Password=bar;";
Problem 2: Actually altering the data
Is there a way to modify this database without either upgrading the database or downgrading my access application?
