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?

Hi,
im searching for Methods to compare Images. But i dont want only such simple things like comparing files byte for byte. I want to find pictures that are nearly same.
I have many pictures that have sequences of similar images eg. a series of images that show the same scene but someone moves around a bit or moves an arm up and down. So i want to do some checking for pictures that are not completely the same.
How can i do that or where can i find components that does that?

I have a text file with rows of lines that look like this:
44490825;4;05;00000004;Mike
I would like to know if there is way for me to read the values between the delimiters, which are the semicolons. I know that I can read one character at a time, but that means that I have to add each character to an array slot. I am hoping to be able to read from the beginning of the line to the first semicolon, add that string to an ArrayList, read the next value between the semicolons, add that value to the ArrayList, and so on until I reach the end of the line. I would really appreciate any help, thanks.

Use the Split method to split the string on ';', and you get an array of strings, where each item is a value.

b { font-weight: normal; }

hi Kani
I think you should use string.Split() method there.
Your issue can be solved with following line of code.
<br />
string text = "44490825;4;05;00000004;Mike"<br />
string[] items = text.Split(new char[]{';'});<br />
the Array items will hold each string in ';' as each array element.
So try this out Kani

I have some applications that currently use a list control to display status messages from the process. As time goes by, the number of messages in the list would grow without bounds if I did not limit it. I do this by checking if adding a new message will make the line count go over the configured maximum. If so, I delete the first line in the control and then add my new line. There is no real need for the user to interact with the list other than to read it, possibly using the scroll bar. The list control has one column, wide enough for a reasonable length message.
The difficulty with this is that it causes a lot of flashing of the control, whether or not I ensure that the newly added line is visible. If messages are rapidly being added to the list, the list can go completely blank for periods of time while tons of updating is going on.
So what is a better way? I'm open to anything, particularly to using something other than a list control. Essentially, I'm trying to mimic how a read-only command prompt window works. Once it gets a certain number of lines in it, new lines cause old lines to disappear, with no annoying flicker.
Thanks in advance.

You may want to envelope your calls to add an item (and remove the first item when the list control is full) between a pair of SuspendLayout() and ResumeLayout() calls.
To further increase performance, you may want to consider deleting the first n items (and not just the first item) when the list control is full.

Hi All,
Since my last post on Design Patterns, I've been reading up on them and in particular the Observer Pattern, as I think it's the right tool for my specific task.
My scenario is this: I have a small(ish) application which uses a barcode scanner to read barcodes (naturally). Various parts (forms) of the application need to be able to accept the data from the barcode scanner (although not all at once, which I manage on a focus basis). To this end, I created a BarcodeScanner class as a Singleton, so that only one instance exists and so that it has public visability; I also created an event in this class so that it can notify any listeners when a Barcode has been successfully read. Each form that needs to read barcodes simply attaches itself as an Event receiver and so can listen (observe) the barcode scanner class.
And this all works pretty well, which is the important thing. But what I'd like to know is, is this an example of the Observer pattern as implemented in C#? Most of the articles I've read on the subject are great at explaining the abstract concept, but rely on the reader's intelligence ( ) to work out the implementation details for themselves.
Cheers,
Martin.
