You should initialize all object before using, I didn't see your code, but error message says that!

Has IDMAT duplicated values?!

the cursor file (.cur)

Save the selected image as binary data, I think MS Access supports Binary datatype, no need to convert it to matrix.

Give me sample of your code especially when you read via DataReader

Edit the form code generated and add this line
this.Cursor = new System.Windows.Forms.Cursor(CursorPath);
It works with me well.

http://msdn2.microsoft.com/en-us/vcsharp/default.aspx you'll find a lot of videos, articles and samples!

Give us the error raised!

Please move your thread to http://www.daniweb.com/forums/forum18.html

See the documentation of (System.IO.FileInfo) class it would help you

Change ComboBox DropDownStyle to DropDownList, it forces user to select ComboBox items...

Sorry for being late as I was in Army last two days..

SELECT     Category_1.Name
FROM         Category LEFT OUTER JOIN
                      Category AS Category_1 ON Category.ID = Category_1.ParentID
WHERE     (Category_1.ParentID = 1)

When you trying installing your already installed application, it confirms if you need to uninstall it or not!

Thanks Jerry :)

I've answered you how to save the status of controls in your previous thread!

tabControl1.SelectedTab = tabPage2;

If this database resides on the server, type its name and use your suitable authentication options and select target database from databases downlist.

SELECT     dbo.Category.Name, dbo.Category.ID
FROM         dbo.Category LEFT OUTER JOIN
                      dbo.Category AS Category_1 ON dbo.Category.ID = Category_1.ParentID
WHERE     (Category_1.ParentID IS NULL)

Try to re-develop all projects you did by COBOL and Basic by C#

Project->add new item->Settings file

but, if you need to save some properties of the controls, I recommend to use .settings file

Extract the generated code by VS IDE, save it to the text file.

You can use ProcessStartInfo class to help you I am attaching an example it could help

This example I wrote to help me to generate key file for com and com+ applications

public void GenerateKeyFile(string path)
        {
            string commandLine = " \"C:\\Program Files\\Microsoft Visual Studio 8\\SDK\\v2.0\\Bin\\sn.exe\" -k ";
            ProcessStartInfo PSI = new ProcessStartInfo("cmd.exe");
            PSI.RedirectStandardInput = true;
            PSI.RedirectStandardOutput = true;
            PSI.RedirectStandardError = true;
            PSI.UseShellExecute = false;
            Process p = Process.Start(PSI);
            System.IO.StreamWriter SW = p.StandardInput;
            System.IO.StreamReader SR = p.StandardOutput;
            SW.WriteLine(commandLine + path);
            SW.Close();
        }

public void YourMethod([b]int[] arrOfInts[/b])
{
//your code goes here..
}

but all in all MSDN is the best for ever, I didn't learn C# from a book, everything I look at MSDN and some methods documentation and some trying...

I recommend Inside C# and How to program

First Withdraw shoud be public and some methods too

public Withdraw(int account, int amount)
{
Account.numberOfWithdrawal++;
..... // rest of code
..... // rest of code
}

I see you hardly need to read in OOP before programming with C#, you won't do true projects with C# before fully understanding the concept of OOP.

each withdraw increment the numberOfWithdrawal

Thanks :)

[ComboBoxName].Item.add(....)

define your users and from user properties define "User mapping" to set and remove some privilages

class XYZ
{
string str;
public string Str
{
get { return str; }
set { str = value; }
}

public XYZ(string str)
{
this.str = str;
}
}

Show us your effort to help you, friend! your question is straightforward!
You just need to read about if else in C#.

So your new question is how to pass a value (text) of the textbox in a form to another form (which has the control you want to change its text??!!)

Control Text or control Name ????
if you've button you can change its text by
yourButton.Text = "lmlmalaa";
please clearify your question

that's may help www.connectionstrings.com

Yes, you can!
OnSpecificEvent(....)
{
[Control].Name = "new name";
}

There are third party controls for charting and they are integrated with .net, search and play with them.

Forward your question to asp.net forum
http://www.daniweb.com/forums/forum18.html

On your application or generally??

try to run your application as administrator and feed me back!

You can't add two bytes!

I am sorry, I don't know abo Oracle please put your question at http://www.daniweb.com/forums/forum129.html
and you'll got a lot of replies
Thanks

Look, Client sends to Server some messages, right?!
And Server has OnReceive method that raises when it receives new messages, right?!
Server can parse the message, so we can append any message any string and let the server parse it and according to the string, server take an action, let's say
1-
Client sent this message "file I am daniweb user"
Server received this message, then it parsed it and switch
case "file":
SaveFile(string);
2-
Client sent this message "reply I am daniweb user"
Server received this message, then it parsed it and switch
case "file":
SendClientMessage(string);

and so on..

You add reference to COM library, but no visual design shown unless COM library contains visual control. like flash player, media player once you add it on your form it shown, but some libraries does not contain any visualization, so you won't be able to see them.

Sure, you do something wrong! send me the code ramymahrous@gmail.com

Crystal report reports can be merged in your application (You don't need to call report from Server) just connect to your Oracle DB Server.

No difference instead you put A4 paper put envelop, just put data in organized way, say address on top right .... or you can use MS Word envelop template and integrate with MS Word via VSTO to put each field in its place.

Crystal report: is a tool for designing reports and complicated one also, can viwed inside Windows or Web-based applications.

You can't call method from SP, but verse is correct.
