It is the first time for me to try to publish my project within VC#2005.
after it is published, after I instelled on my own computer, when I run the .exe, it gives the
error message: some .txt files (this files are used by the prject) can note be found. I don't know how to solve this problem.
in which way, these files using by the project can be found.

I Assume you have created a Windows App, now if you want to create an exe for your Aplication, is good if you create a Setup Project, Did you do that or am missing the point?

you are right, I did everything you said. I have setup project, and also I can installed it.
everything is fine except some .txt files can not be found.

Can i get a logic of your Application, Do you Write to a File or what do you do? Because when you create an Empty Setup Project , it has nothing on the File System. If you are for example Writting to a Textfile and you did not include it in your Setup Project, dont expect to get it in the Destination Computer, make sure that all the Files that are needed by your Program to run are in one Place and they are all included in the SetupProject, if you have an external file, Right Click on the Setup Project and select FileSystem and you will fine the Application Folder , Right Click on it and Add the Files that your App will need to run in the Destination Computer.

Hi mate,
I had the same problem when I first started using Visual C# 2008 Express Edition. I created a project that required 3 text files on the users computer. But, what I didn't know was that in order for those files to exist on the users computer, you need to either ijnclude them into the project as resources, or add the text files to the installation package. I hope this helps.
Regards,

Hi there,
When I use the following code below I get and error called , "concurrency violation" and the database is not updated.
I am able to connect and retrieve data. but I cannot update the data from the datatable of dataset.
I am new to datagridview and datasets.
I am using Mysql 5.0 and Mysql connector .NET 5.1.2
I read many articles on updating the dataset and almost tried everything , but It does not work, I can update to Mysql database using update commands. But I want to use Dataset or dataadapter update to make it more simpler.
public partial class Form1 : Form
{
DataSet ds = new DataSet();
MySqlDataAdapter da;
DataTable dt = new DataTable();
string tabname;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
CreateMySqlCommand();
}
// Connecting to db and filling the datagridview with data.
public void CreateMySqlCommand()
{
MySqlConnection myConnection = new MySqlConnection("Persist Security
Info=False;userid=root;password=XXXX;database=test;server=terrain");
myConnection.Open();
MySqlTransaction myTrans = myConnection.BeginTransaction();
string mySelectQuery = "SELECT * FROM patient_master";
MySqlCommand myCommand = new MySqlCommand(mySelectQuery,
myConnection,myTrans);
da = new MySqlDataAdapter(mySelectQuery ,myConnection) ;
MySqlCommandBuilder cmdBldr = new MySqlCommandBuilder(da);
da.Fill(ds);
dt = ds.Tables[0];
DataRow row;
row = dt.Rows[0];
int lirow = dt.Rows.Count;
string mrno = row["MRNO"].ToString();
string patname = row["GIVEN_NAME"].ToString();
dataGridView1.DataSource = ds;
dataGridView1.DataMember = ds.Tables[0].ToString();
tabname = dt.TableName;
int y = 0;
foreach (DataGridViewRow ro in dataGridView1.Rows)
{
if (y % 2 == 0)
ro.DefaultCellStyle.BackColor = Color.Red;
y++;
}
}
// code on the button to update the datadapter
private void button1_Click(object sender, EventArgs e)
{
da.Update(ds, tabname);
}
}
}

Hi,
I am working on Sign In and Sign Up functionality for my website.
Both options are on same page with two validation summary controls.
Sign In
I have 2 text boxes for Sign In [ User Name and Password ]
I have 1 Submit[Sign In] button which submits user name and password to server, its CausesValidation property is set to true for validation.
For each text box I am using 1 'required field validator' control.
For these text boxes I am using 1 Validation Summary Control.
Sign Up
I have 3 text boxes for Sign Up [ User Name, Password and Confirm Password]
I have 1 Submit button[Sign Up] which submits user name, password and confirm password to server, its CausesValidation property is set to true for validation.
For each text box I am using 1 'required field validator' control.
For these text boxes I am using another Validation Summary Control.
While working with mouse, both validations are working fine.
If I click on 'SignIn' button, first validation summary control's message box pops up.
If I click on 'SignUp' button, second validation summary control's message box pops up.
The problem is,
If I am a new user and trying to Sign Up. After providing required info, UserName, Password and Confirm Password... and ***** Press Enter ***** instead of Click 'Sign Up' button, it displays 'Sign In' validation Summary message box. Actually it should display 'Sign Up' Validation Summary message box.
Please help me to solve this problem.
Thanks.....

The problem is that your sign in button has focus when you press on enter its event is fired.
So over come this problem, you have to register onfocus event of any textbox in signup panel. e.g text box for confirm password.
Then do the following in onFocus event of confirm Password text box.
textBoxConfirmPassword.Attributes.Add("onkeydown", "if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('"+btnSignUp.UniqueID+"').click();return false;}} else {return true}; ");

Can someone please assist?
How can I pass a DataSet from the DataAccessLayer to the BusinessLogicLayer? Currently the DataSet gets populated successfully but as soon as the execution returns to the BusinessLogicLayer, the DataSet is null.
My DataAccessLayer Method looks something like this:
public object GetData(DataSet dsMyDataSet)
{
return dsMyDataSet;
}
My BusinessLogicLayer looks something like this:
public object GetData1()
{
datalayer = new datalayer();
datalayer.method();
}
Illegal Operation

Illegal Operation wrote: public object GetData(DataSet dsMyDataSet)
Why not returning the DataSet itself instead of object?
datalayer = new datalayer();
DataSet ds = datalayer.method();
I'd suggest to debug the code and findout why it is NULL. Also use strongly typed DTO's to transfer data between layers instead of DataSet/DataTable. Check this[^]

hi Illegal Operation
Why do you return an Object? You asked me an Unclear Question in my Article. Let me explain Briefly.
Illegal Operation :Wrote
My DataAccessLayer Method looks something like this:
public object GetData(DataSet dsMyDataSet)
{
return dsMyDataSet;
}
In your Getdata Function, you are Doing strange things, you return an Object and you asked us how to pass a dataset across DAL and BLL, First you have to change that object to a Dataset, and another thing in your Parameters, logically i dont know what you are trying to do. Your are accepting a Dataset as a Parameter and at the same time your want to return a dataset. When you getdata,it must be either void or search using something like string ,int etc not dataset. If you want to Pass the Dataset in this case you can change you function to look like this
public Dataset GetData()
{
return dsMyDataSet;
};
and lets come to your BLL
Illegal Operation :Wrote
My BusinessLogicLayer looks something like this:
public object GetData1()
{
datalayer = new datalayer();
datalayer.method();
}
Here again you return an Object, with what control are you going to bind the Object? Your Code
datalayer = new datalayer();
will not Compile, you did not create an Object of a Class. Your BLL Should look like this
;
public Dataset GetData1()
{
datalayer obj = new datalayer();
Dataset ds = new Dataset();
ds = obj.GetData();
return ds;
};
After you have this , you can bind it to any Control that you like.

Hey,
I have downloaded your source and saw that you instanciated a dataset in the PL before the method.
Anyway, your code has helped me solve my problem and for that I thank you!! I see that you are from South Africa?
I am also from South africa but I currently work as a software developer in Australia. For what company do you work? I worked for Business Connexion.
Thank you again for the article - it made a LOT of things clear...

Hello.
I am SourceGrid beginner.
The version uses 4.11.
The following tables were made.
|aaaaaaaaaaa|
|bbb|ccc|ddd|
1 |
2 |
3 |
4 |
5 |
6 |
7 |
8 |
9 |
10 |
The first lines unite with columnspan.
Can able to be made it to scroll and how do by me without at that time though the line between ccc and ddd can be scrolled during bbb and ccc of the second line?
Moreover, RowHeader can be scrolled between line - numbers. Is there a method of not allowing this to be scrolled?
My best regards.

Hello everyone,
According to MSDN, we should "make exceptions serializable". I think it means we should implement the constructor which accepts SerializationInfo and StreamingContext as input parameter, correct?
If yes, could anyone show me how to implement it please?
http://msdn.microsoft.com/en-us/library/ms229064(VS.80).aspx
public class MyException : Exception
{
private int _errorCode;
private string _errorDescription;
public MyException (int errorCode, string errorMessage)
: base (errorMessage)
{
_errorCode = errorCode;
_errorDescription = errorMessage;
}
protected MyException (SerializationInfo info, StreamingContext context)
{
}
}
thanks in advance,
George

[Serializable]
public class MyException : Exception
{
private int _errorCode;
private string _errorDescription;
public MyException (int errorCode, string errorMessage)
: base (errorMessage)
{
_errorCode = errorCode;
_errorDescription = errorMessage;
}
protected Public MyException (SerializationInfo info, StreamingContext context)
: base(info,context)
{
this._errorCode = info.GetString("ErroCode");
}
}BTW, I have seen the same in MSDN forums too

Thanks Navaneeth,
Why you remove my string class member?
regards,
George
|
|
|
|
|
Base class Exception provides a member Message which can be used.
|
|
|
|
|
Thanks Navaneeth!
This constructor is called when an instance of type MyException is deserialized from a stream? So, the constructor is used in de-serialization process, not serialization process?
MyException (SerializationInfo info, StreamingContext context)
regards,
George

I don't think so. Deserialization has to take place outside of the exception class and pass that SerializationInfo to this overload which will fill the necessary fields of this exception.

Thanks Navaneeth,
I am confused about -- "Deserialization has to take place outside of the exception class and pass that SerializationInfo to this overload which will fill the necessary fields of this exception." Especially confused about what means "take place outside of the exception class"? Could you show me some simple pseudo code please?
have a good weekend,
George
