 you both on the same course? and the answer to your questions is of course - no, you cant have the code.
Look into the System.Data.SQLClient classes and give it a go yourselves.
And might I suggest a better explanation of your problem too

here is my code :
TestDataSet ds = new TestDataSet();
private void Form2_Load(object sender, EventArgs e)
{
TestDataSetTableAdapters.CustomersTableAdapter cA = new TestDataSetTableAdapters.CustomersTableAdapter();
cA.FillCustomers(ds.Customers);
TestDataSetTableAdapters.OrdersTableAdapter oA = new TransactionalUpdate.TestDataSetTableAdapters.OrdersTableAdapter();
oA.FillOrders(ds.Orders);
dataGridView1.DataSource = ds.Customers.DefaultView;
dataGridView2.DataMember = ds.Orders.ParentRelations[0].RelationName;
dataGridView2.DataSource = ds.Orders.DefaultView;
}
can anybody help me to solve this problem ?
Thanks

hi I need to implement a formula translator in C#.
As an input I have a validated mathematical formula string such as "a+b*c+(c/d)".
I want to calculate this formula at runtime when parameters (a, b, c & d) are available.
As far as my application is concerned the formulas used will always be simple algebraic ones(as shown in the example)
Is there any existing facility in C# to do this?
OR any suggestions to implement this on our own?

There are, for instance, articles [^].

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Someone out there must be able to help me...
I'm trying to find/design a way of automating my project's builds, publishing, versioning in VSS etc and I'd like to create an app/script that will obey my command and do in one easy button click, what would otherwise take copious amounts of time & attention.
The general idea is: Build a project/solution based on the .*proj files, publish the project with different config settings & install location depending on whether the app is going to QA, Pre-Prod or Production. I would also like to be able to have Source Safe's labelling done automatically.
So far, I have found that Microsoft's MSBuild Reference on MSDN is virtually useless (  ???), but I have been able to compile a project via the command line using it.
I found that Microsoft.Build.BuildEngine looked perfect for what I'm trying to acheive, however, using the following code, I can't get it to build the project:
Engine engine = new Engine();
Project project = new Project(engine);
project.Load(strProjFile);
project.Build();
The Build method on the Project keeps returning False - no error, nothing. (Before you ask, yes, the path to the project file is correct - the same file builds fine through VS2008 as well as MSBuild)
(Oh, and again, Great Job Microsoft on the crummy documentation)
If anyone has an idea of where I am going wrong, please, please, please! Let me know

Do you try to build a Continous Integration system?
I would suggest using CruiseControl.NET. We accomplished that on a check-in to VSS the projects are compiled, unit-tests will run, documentation and release notes generated and at least a msi-file will be created.

It appears that if you add logging, you find out what the problem is...
Engine engine = new Engine();
FileLogger logger = new FileLogger();
logger.Parameters = @"logfile=" + strlogFile;
engine.RegisterLogger(logger);
bool success = engine.BuildProjectFile(strProjectFile);
engine.UnregisterAllLoggers();
if (success)
MessageBox.Show("Build succeeded.");
else
MessageBox.Show(@"Build failed. View " + strLogFile + " for details");
Using the above code, I was able to view the log of the issue:
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.WinFX.targets(64,7): error MSB4127: The "GetWinFXPath" task could not be instantiated from the assembly "PresentationBuildTasks, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35".
This issue in turn needs the following config file settings to be added:
<configuration>
<configSections>
<section name="msbuildToolsets" type="Microsoft.Build.BuildEngine.ToolsetConfigurationSection, Microsoft.Build.Engine, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</configSections>
<startup>
<supportedRuntime version="v2.0.50727" safemode="true"/>
<requiredRuntime version="v2.0.50727" safemode="true"/>
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.Build.Framework" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-99.9.9.9" newVersion="3.5.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
<!-- To define one or more new toolsets, add an 'msbuildToolsets' element in this file. -->
</configuration>
My project builds!

Has anyone else had issues similar to this?
If a row is selected in the DataGridView on a form the following event handling code correctly gets the index value of the row. However, the code to extract values from the row actually gets values from the next row. For example if the fourth row is selected, index has the correct value of 3 but the row values are from the fifth row. Decrementing the value returned from vDateDataGridView.CurrentRow.Index then referenced the third row! Decrementing and then incrementing the value again referenced the fifth row. If the index value is assigned from a constant (e.g. index = 3), the problem does not occur.
string str;
int index;
index = vDateDataGridView.CurrentRow.Index;// gives correct index
str = vDateDataGridView.Rows[index].Cells[0].Value.ToString();
str = vDateDataGridView[0, index].Value.ToString();
CurrentRow.Index supposedly returns an int, but this behaviour suggests rounding issues or similar. Recasting after using the CurrentRow.Index.ToString() function did not make any difference.
I have replicated this behaviour in a fresh form in the same project. The underlying data source is a View joining three tables. I will see if the same problem occurs with a single table datasource. Yes, it did.

does sound very strange. Have you tried using...
str = vDateDataGridView.SelectedRows[0].Cells[0].Value.ToString();

Yes, literals work as expected.
This code to handle the CellClick event works as expected (currentRow and currentCol are declared as form properties).
private void vDateDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
{
currentRow = e.RowIndex;
currentCol = e.ColumnIndex;
string str;
str = vDateDataGridView[currentCol, currentRow].Value.ToString();
selectedCellLabel.Text = str;
}
But when the following line is executed in the other event handler, currentRow behaves as before!
str = vDateDataGridView[currentCol, currentRow].Value.ToString();
The workaround is to declare currentRow and currentCol as local variables in the CellClick event handler, declare the variables I want to extract from the DataGridView as form properties and get their values in the CellClick event handler.

I am novie to the Regular expression validatio. my req is a regular expression for currency with thousand seperatror which is decimal(14,3) ... checked the all availabe but no use.. pls help me to get it..(pls Note the regulare expression should restrict to decimal(14,3)

maybe you could put some examples of valid/invalid input so we can better understand your requirements

eg 1,12,000.00, 22,22,333.90 are valid but 12,33,333,444,444.900000(more than 11 preceding the point and more than 3 field afer the point)
|
|
|
|
|
what about...
string regexString = @"^[0-9,]{0,14}.[0-9]{0,3}$";
NOTE: i use 14 before . to allow for the 3 commas possible

I write ExecuteDataSet function;
public DataSet ExecuteDataSet(string commandText, string tableName, SqlParameter[] parameters)
{
try
{
OpenConnection();
using (SqlCommand command = new SqlCommand(commandText, this.connection))
{
command.Parameters.Add(AddParameter(command, parameters));
using (SqlDataAdapter dataAdapter = new SqlDataAdapter(command))
{
DataSet ds = new DataSet();
dataAdapter.Fill(ds, tableName);
CloseConnection();
return ds;
}
}
}
catch (Exception ex)
{
//Exception Log
CloseConnection();
return null;
}
}
I wan to call AddParameter() fuction in the using block. Bu I get error.
private SqlParameterCollection AddParameter(SqlCommand command, SqlParameter[] parameters)
{
foreach (SqlParameter param in parameters)
{
command.Parameters.Add(new SqlParameter(param.ParameterName, param.Value));
}
return command.Parameters;
}
How can I do?
AddParameter() using in a lot of function. If I write foreach loop in the using block so code is repated a lot.
