Hi! I have one issue and I am sure that many guys here know how to help me. I am building a web application in ASP.NET with C#, and now I have a dropdownlist connected to the field in the database, and I have a label, and I want to display other value from the database there. Like, I am selecting my name in the dropdown list, and in the label it should display my second name. Thanks ahead

Hi
To do the same the simplest way is use Selected Value property. At the time to binding the combobox you could assign the Display member property with your First name field and the value member property with your last name feild.

Then in combobox event you could choose the item displayed due to display member property and set the text of selected value property according to the member you choosen.

Possible to transform a MDX cellset into a 'normal' SQL resultset?

Hi folks,

last week I've been thrown into two new techniques: MDX and Dundas maps.

The task is to query a cube for region-related data and display them in a report using a Dundas map (for Reporting Services) of Germany.

I don't have difficulties getting the data via MDX, and with a similar (faked) SQL query result I can use the map. Looks great.

When I connect the MDX 'dataset' to the map, everything seems to fit - but when viewing the report ist insists there would be no data...

At the Dundas support forum I've been told that
<quote>The map control for SSRS is not designed to accept data from an OLAP cube, it expect the data to come in a "flat" form which is simply a certain number of columns and rows.

The helping hand at Dundas asked me <quote>Is it possible to write an MDX query that will produce a flat result set? - and I have to pass the question on, for I haven't found a way yet... Frown | :-(

Any suggestions welcome!

Cheers,

Juergen

I basically need to know the best, easiest way for a user to transfer MS Access table data via e-mail to another Access Database table.

.1)Export the table to a flat file via an export wizard or VBA code.
.2)Zip the file.
.3)Email the file to the recipient.
.4)The recipient unzips the file.
.5)On the recipient's computer the database either has an import VBA method or the user imports the table via a wizard into the database.

Hi, I am using dataset for playing with data and wanted to create an additional column that stores logarithm (log) of another column. I tried to use number of options including the one below but still have trouble making the program work.

dtRec.Columns.Add("sumXY", Type.GetType("System.Double"), Math.Log("recflow"))

recflow is an existing column of the dataset and I want log values of reflow to be stored in new sumXY column.

Any suggestions!!

First of all, don't mark your posts as URGENT. You're not paying anyone for their help, so be prepared to wait.

You haven't stated what type of database you are using. Presumably it is file-based, Access maybe?

Connection strings for Access require an absolute path to the database file. You will need to construct connection string with the path to the database file yourself in code. You can get the path that your application is executing from by calling Environment.CurrentDirectory. Then append the name of your Access database file.

I tried it but not there is a 2nd problem which is as follows:

my code is:

string currentDirectory = System.Environment.CurrentDirectory;
OleDbConnection con = new OleDbConnection();

con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + currentDirectory + "\\dbLetters.mdb';Persist Security Info=False";

this.oleDbInsertCommand1.Connection = con;

//other parameters

this.oleDbInsertCommand1.Parameters["Subject"].Value = this.txtSubject.Text;
this.oleDbInsertCommand1.Parameters["RefNumber"].Value = this.txtRefNumber.Text;
this.oleDbInsertCommand1.Parameters["RefDate"].Value = this.dateTimePicker1.Value;
this.oleDbInsertCommand1.Parameters["OutwardNumber"].Value = this.txtOutwardNumber.Text;
this.oleDbInsertCommand1.Parameters["OutwardDate"].Value = this.dateTimePicker2.Value;
this.oleDbInsertCommand1.Parameters["FileNumber"].Value = this.txtFileNumber.Text;
this.oleDbInsertCommand1.Parameters["Remarks"].Value = this.txtRemarks.Text;

con.Open();
this.oleDbInsertCommand1.ExecuteNonQuery();
con.Close();

-------------------------------

Upon execution , it is not creating a new record but always updating the last record and I have no clue to why is this happening. Frown | :(

Plz guide me . I shall be really thankful 2 u

INSERT INTO tblOutgoingLetters
([To], [From], Subject, RefNumber, RefDate, OutwardNumber, OutwardDate, FileNumber, Remarks)
VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)

this is the command that I have in the CommandText property of Command object..but instead of inserting a new record into the table , it is changing the content i.e. updating the last record

Do u have any idea about why is this problem occurring?

This is actually a problem with you program logic. Insert statement can never update another record. So check your logic may be on insertion the program calls the update function.

Do good and have good.
