I created a small Windows form using C# that add and remove text from a file. To run the Windows form a user just need to click on the "Enablelog.exe." The "Enablelog.exe" only has a name attached to it(Enablelog.exe) which make it looks very plain. Can some one show me how I can add an image to it so that it will be on the "Enablelog.exe" and make it looks more professional. I am using Visual Studio 2005.
Any help will greatly be appreciated,

Try using an Icon
If you created the project with Visual Studio then you should have a "app.ico" or something like this into the project files 
protected internal static readonly ... and I wish the list could continue ...
|
|
|
|
|
In your project's property => Application pane => you'll find a ComboBox to choose an icon for your application.

Hi
I'm trying to send mail through the MailMessage object.
I know that the body property of the message receives a string.
I wanted to know if there is a way to set the body of my mail to load an HTML file (or any other file, for that matter) so that the mail will not consistof a text only.
thanks

System.Web.Mail.MailMessage msg;
System.Web.Mail.SmtpMail.SmtpServer = "your.smtp.server.com";
msg = new System.Web.Mail.MailMessage();
msg.BodyEncoding = System.Text.Encoding.ASCII;
msg.From = txtFrom.Text;
msg.To = txtTo.Text;
msg.Cc = txtCc.Text;
msg.Bcc = txtBcc.Text;
msg.Subject = txtSubject.Text;
msg.Body = txtBody.Text;
System.Web.Mail.SmtpMail.Send(msg);

Hi everybody,
Is there an attribute or some other way to validate that a property has a unique value.
To illustrate what i mean, watch the "Name" property in the property grid of each control added to a windows form. It is unique!
How can i achieve this capability too?
Thanks in advanced,

Hi all,
i am going to write window form application in C# that has TextBox and other control on it. i want to support two languages input for same one textbox depending on user selection via some radio buttons. i have searched on internet but all the posts say language can be changed for current thread. this means it will change language for all the controls on the from. please help me how can i change language on one particular textbox on run time.
Regards,
Omar Lodhi

first you must know you can not install/uninstall language supports in windows itself. That means that you can only support these languages only if they are supported by the user's windows.
Now to the issue. You can handle two events to manage that: Enter, and Leave.
In the Enter event handler you set Application.CurrentInputLanguage property to whatever you want, then on Leave event handler you change it back to the original.

Hello friends need help here..
Before this I have learn to create password validating form.Which is user have to key in password to enter another form. The password is default that have set in the coding.Now I need help how to connect to MY Sql database from C# from and compare the password that already I set in MY Sql database,table name Security and Field name password and the password is "ABCD".I dont know how to use SQL server 2005.
Below are the coding for the first form that validate to enter to form2.
//////////////////////////////////////////////////////////

textBox1.PasswordChar = '*'; //Masking Char
textBox1.MaxLength = 14;//Max Length is 14

string strDefaultPassword = "security"; //Keep the default password
string strEnteredPassword = textBox1.Text;

{
this.Hide();
form1.ShowDialog();

MessageBox.Show("Wrong password entered");

How to change this to connect to MY Sql Database and compare the password from the database.
Tq in advance......
|
|
|
|
|
In the validation procedure (button1_Click) connect to the mysql database with a special driver (either odbc or a dedicated one from the mysql site) - check http://www.connectionstrings.com/[^] for aditional info.
Use ado.net to retrive the password for your user (dataTable, dataTableAdaptor and other stuff like this - check articles for this on codeproject).
The database querry should return only one value (the password) for the specified user. And olso, try to use parameters with regex in the querry to aviod insertion attacks.
Good luck.

If you programmed that service you can use Remoting to communicate between your application and that service, and then call that method.
If not!! Then I don't think you'd be able to do it.

I have the RichTextBox. And I was wondering how would I be able to how the user to place a table into the RichTextBox?

Hello everyone,
I need some idea since I am running out of my own and haven't been able to get it working.
I have a file called temp.txt which hold temparary data and will be deleted at the end of the Windows Application life. I have another file called perm.txt which is similar to the temp.txt file but it hold the saved data.
In order to avoid multipler data registration I would like to check to see if a particular data from temp.txt file has already been registered or not. If it hasn't then I will go ahead to save/register it into save.txt file. That is if the user choses to Save its temp.txt content by clicking on the SAVE button.
Any suggestion in this issue will be greatdly appriciated. Thank you very much and have a great day.

I don't quite understand the problem/question.
As I understand the situation:
You save data in a temporary file which is deleted when the application exits.
There is another permanent file where the data in the temporary file is written/moved as long at the data doesn't already exist in the permanent file.
This would require your code to perform the following:
Read a record from the temporary file.
Read the contents of the permanent file searching for a matching record.
If no record is found in the permanent file, append the permantent file with the new record.
Depending on the size of the files and number of records, you may be able to read both files into memory when making comparisons and after any additions, simply write out a new permanent file from the records in memory.

In addition to what Wayne Phipps said, I'd suggest that you store the records as Hash codes in a HashTable. This way you can compare small integers instead of large records, which could boost your performance dramatically.
