You actually should do both (specify the correct working folder and using cmd.exe).

Crystal report

Hello,
I am very new to Crystal Reports and i am trying to implement specific report format.
I have programmatically created some data tables (using SQL queries) which are to be displayed in grid format in report.

Each Data Table corresponds to one column data and they are mapped with the Data Tables created in DataSet . I am using Standard report to display data but i don't know how to display the data in grid layout.

I tried to use Cross Report but i don't want to group the data or count and other unnecessary fields.
Also, all columns are not having equal no. of rows so the Box object and Line object are not solving my purpose if i use Standard Report.

Please see the report format image at http://sites.google.com/site/gridformat

I have the data ready with me but i am struggling to wrap it out with specified grid layout.
Please tell me how to generate the grid with merged column header and fill the data in it?

Thanks in advance.

RadioButton is an ordinary class so to create new instance you just need to call its constructor and assign it some variable. Like this: RadioButton rd = new RadioButton() It has a property called Text so you can use it to set its text. The text can come from any source. rd.Text = myTextBox.Text

Note the radiobutton will not be visible if you don't add it to a form or container control.

Question of Convert XML data to DataTable

leejs4135-Nov-08 15:13

5-Nov-08 15:13

I am programming a movie info collect tool. I think store all data with XML is OK.
Here is the MovieDataXML

<?xml version="1.0" encoding="utf-8" ?>
<Data>
  <Movie>
    <ChineseName>aa</ChineseName>
    <EnglishName>aa</EnglishName>
    <Year>aa</Year>
    <Area>aa</Area>
    <Type>aa</Type>
    <Language>aa</Language>
    <Subtitle>aa</Subtitle>
    <IMDB>aa</IMDB>
    <Resolution>aa</Resolution>
    <Director>aa</Director>
    <Actors>aa</Actors>
    <Introduction>aa</Introduction>
    <BelongTo>aa</BelongTo>
    <DiscNumber>aa</DiscNumber>
  </Movie>
</Data>

And when I try to read the data.

//clsXmlHandler is a class to read the xml data
ClassXMLHandler clsXmlHandler = new ClassXMLHandler();
string strMovieData = "Data";
XmlNode xNodeMovieData = clsXmlHandler.MovieDataDocument.SelectSingleNode(strMovieData);
XmlNodeReader xReader = new XmlNodeReader(xNodeMovieData);

Here is the problem
If I read XML data by DataTable
There will be a Exception "DataTable does not support schema inference from Xml",
If I create this DataTable schema manually,there is no data in that DataTable.

DataTable dtMovieData = new DataTable();
dtMovieData.ReadXml(xReader);

But I found it is OK if I use DataSet instead of DataTable

DataSet ds = new DataSet();
ds.ReadXml(xReader);

I don't know why.

What about

- yourstring.Split(new char[] { '\n' }) or
- yourstring.Substring(0, yourstring.IndexOf('\n') or
- Regex.Match with pattern @"^([^\n]+)\n.*"

regards

\n or \r\n are concidered new lines.
if you load following string:

"test\r\nmore test"

in a multiline textbox it will appear:

test
more test

Although all the solutions that has been mentioned will work, I just thought I would mention another one Smile | :)

string value = "6.623E-2\n,#wz4y";
string ans = value.Substring(0, value.IndexOf("\n"));

Since you can't stored just any old character you want in an XML file, you'll have to convert the image to a string that XML can hold. A thought off the top of my head says convert it to a base64 string and store that.

As said above, you can use Base64:

Make your image node of type xs:base64Binary[^].
Then, you can use System.Convert.FromBase64String[^] and System.Convert.ToBase64String[^] to read and write the binary value.

SQL Server Express - How many querys per a second can it handle?

Brad Wick5-Nov-08 12:52

Brad Wick

5-Nov-08 12:52

I have a application I have built that uses a SQL Server express database to store the data. I have built a logging functions which writes the log entrys of whats going on in the application to a text file on the hard disk. When I set the logging to DEBUG mode (which logs a ton of stuff) it takes a long time for certain things to run as its writing a bunch of data to the text file. If they set the logs to WARN... it only writes important information to the log file.

This all works great, but I would really like to log everything so if there is a problem with the application I can look at the users log file and tell exactly what they were doing to try and reproduce the error. So I was thinking about writing the logs to the database which would mean I could insert all entrys and just query the items I need to return which brings up my question.

If i start to insert a ton of data into the database, at what point could I overload the database?

XXX Querys a hour/second?
Database reaches XXX size?

I know this will depend on the users machine also, but its not going out to a wide user base, more like 10 people.

This is just 1 of the considerations. Database design will have a big impact, as will proper connection control and a whole host of other things. I suspect the only real way of finding out is to test it.

Not Getting Data Back From Stored Proc Call

Kevin Marois5-Nov-08 10:28

I am passing in the procedure name and a parameter array. The values in the array are correct, yet I'm not getting any data back:

public DataSet ExecuteQueryProc(string sParameterName, SqlParameter[] ParamArray)
{
    DataSet oDataSet = new DataSet();

    SqlConnection oConn = GetConnection(true);

    if (oConn != null)
    {
        SqlCommand oCommand = new SqlCommand();
        oCommand.Connection = oConn;
        oCommand.CommandText = sParameterName;
        oCommand.CommandType = CommandType.StoredProcedure;

        oCommand.Parameters.AddRange(ParamArray);

        SqlDataAdapter oAdapter = new SqlDataAdapter();
        oAdapter.SelectCommand = oCommand;
        oAdapter.Fill(oDataSet);

    }
    return oDataSet;
}

oConn equaling null would result in no data.

Just because we can; does not mean we should.

Have you tried running the proc in query analyser with the EXACT paramters you are passing? Its often easy to get a trailng space on a string that results in no data, or similar problems. I often just do a bit of code to generate the exact call (with the param values in the correct quites etc), then test it in query analyser.
