You could create COM component using native C++,register it and and next create runtime callback wrapper for the component.After doing it you could add the RCW assembly to your project and directly use it.It's better than using dllImports beacause it allows easy to use COM/MFC/CRT libraries.
It's much more better C++/CLI because this version is not enough scalable -in fact it consumes a lot of resources for type marshaling.I wrote a sample application using C++/CLI an year ago and I was badly surprised how much memory it requires to run-up to three times more than the same app written in C#.That's why COM is the best solution but it's also the most complicated too.

Update SQL Server 2005 table with DataGrid contents

Good morning.

I have populated a DataGridView with a dataset from a query off a table in SQL Server 2005. Now when a user makes changes in the DataGridView and clicks on a 'Save' button, I want the dataset to be updated and the table to reflect the changes. The datagrid is on a form and all the queries are called from the DAL.

My code is as follows:

private void btnQuery_Click_1(object sender, EventArgs e) 
{ 
PwdSecurity p = new PwdSecurity(); 
uipc = this.Parent as UIPCMainForm; 
const string constrallowedBlockTypes = "allowedBlockTypes"; 
DAL d = new DAL(uipc.StrUserName, p.base64Decode(uipc.StrPassword)); 

DataSet ds = new DataSet(); 
ds = d.AllowedTypes(constrallowedBlockTypes); // Returns dataset correctly from method in DAL 

//New code 
BindingSource bs = new BindingSource(); 
bs.DataSource = ds; 
bs.DataMember = ds.Tables[0].TableName; 
dgv.DataSource = bs; 

// End new code 
} 

DAL: 

myConnection = 
new SqlConnection("server=PTLLBNB0DD1\\SQLSERVER2005;database=IPControl;Trusted_Connection=yes"); 

public DataSet AllowedTypes(string Type) 
{ 
string SQL = String.Empty; 
ds = new DataSet(); 
try 
{ 
SqlCmd = new SqlCommand("spGET_ALLOWED_TYPE", myConnection); 
SqlCmd.CommandType = CommandType.StoredProcedure; 
SqlCmd.Parameters.Add("@Type", SqlDbType.VarChar, 50); 
SqlCmd.Parameters["@Type"].Value = constrallowedDeviceTypes; 

if (myConnection != null) { myConnection.Close(); } 

myConnection.Open(); 
SqlAdapt = new SqlDataAdapter(SqlCmd); 
SqlAdapt.Fill(ds); 
} 
catch (Exception e) 
{ 
MessageBox.Show("DAL Layer / AllowedTypes method error. \n\r \n\r" + 
e.Message.ToString() + " \n\r \n\r" + SQL); 
} 
finally 
{ 
if (con != null) { con.Close(); } 
if (aCommand != null) { aCommand.Dispose(); } 
if (adapter != null) { adapter.Dispose(); } 
} 

return ds; 
}

If I had access to the SqlAdapt, I could probably use SqlAdapt.Update(ds), but i don't currently.

Any suggestions?

I want to replace the double backslash with a single backslash. The following code does not work.

pResult.Path = pResult.Path.Replace(@"\\", @"\");

It does not do any replacement at all. How can this be accomplished?

That should work as is. If you're looking at it in the watch window, be mindful that Visual Studio already escapes special characters with a slash. If you click on the magnifying glass (the visualizer), you should be able to see the 'unescaped' version of the string.

How to apply RowFilter for a String Date

Sreedhar Kadiyala11-Aug-09 3:02

11-Aug-09 3:02

Hi,

I'd a DataTable where I'd filled the data using SQL Statement "SELECT CONVERT(VARCHAR,DOB,105) AS DOB FROM TABLENAME".

Here the DataTable is filled with Dates by using the format "dd-MM-yyyy"

My problem is I need to apply the Filter viz., =, >, >=, <, <= on the DataTable based on the input given by the user in the same format "dd-MM-yyyy" irrespective of the datetime setting in the user system.

Can any one suggest on this.

Thanks in Advance

In your select statement include a where clause the would be a built string based on the input the user entered. For example:

"WHERE mydate < CONVERT(DATETIME, '" + "07/01/2009" + "00:00:00', 103)"

Replace 07/01/2009 with logic that would build that part of the string based on the user inputs.

Hi,

Take the input from the user which would be in the form of '=, >, >=, <, <=' and the string with this try to make a filter condition and apply it to the rowFilter of the dataview.You will surely get..

DateTime.TryParseExact() problem?

Hi,

I can't see what's wrong with this code. I am getting "1/2/2009 9:00:00 AM" displayed in the textBox when I'm expecting "1/2/2009 9:00:00 PM". Can anyone tell me what I'm doing wrong here, please?

DateTime dateTime;
DateTime.TryParseExact("1/2/2009 9:00 PM", "d/M/yyyy H:m tt", CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime);
textBox1.Text = dateTime.ToString();

I'm using VS2008 and targeting .NET 3.5 and have "en-AU" as the default Windows culture.

Thanks, Henk.

Please let me know how to add a filter for DataGridView so that the user can enter the filter condition in the corresponding column header to filter the rows that match the condition.

I am new to C#. Requirement is simillar to how it is in Mercury Quality center or TestDirector tools.

Hope the question is clear..

Hi,

Since the DataTable source is assigned to DataGridView, you can filter the DataTable by using
DataTable.DefaultView.RowFilter="ColName=" + ColValue
It will automatically apply to the DataGridView
