Retrieve Data From MarketDataIncrementalRefresh Message?
Sep 30, 2011
How can I retrieve the following values from a MarketDataIncrementalRefresh?
Symbol/Instrument
Offer
Bid
OfferSize
BidSize
I'm familiar with Quote message handling, for example:
If quote.isSetOfferPx Then Offer = quote.getOfferPx.getValue
Tried the same approach on MarketDataIncrementalRefresh, but there are no such methods, and isSetField always returns false although the field does exist.
I need to retrieve the actual text of a message box from another application. When using WM_GETTEXT, the values returned are the title of the message box, and the text of the control button (in this case "OK").
My issue is that what I really need is the actual text message from the box itself. I've been researching this for days and can't find a way to do this. Nothing I have found so far tells me how to do this.
I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

I want to obtain the individual data in rows and columns from my database. I mean after loading the data in a data table.... I think I need some attributes of the data table, so as to obtain data from the rows and columns.
1. user writes he's details (textbox1 for username, textbox2 for password)
2. user hits "Login"
3. application tries to retrive data from sql server. (in this case localhost/127.0.0.1)
4. application retrieves data from test/tables/members
5. if the specified account information matches the servers data, it will let you through to the next form. Else, it will give an error that the user/pass is incorrect.
I am retrieving data from a csv/txt file using oledb driver ConnString = "Provider=Microsoft.Jet.OleDb.4.0; Data Source = " & System.IO.Path.GetDirectoryName(strFileName) & "; Extended Properties = ""Text;HDR=YES;FMT=Delimited""" strQuery = "SELECT * FROM [" & System.IO.Path.GetFileName(strFileName) & "]"
In the last line I am getting following error if the filename is large Is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.
My question - Is there any limit to filename or the select query or there is some pattern which I need to follow?

I am making a survey-application in winforms that is connected to a MySQL database. Now I want to show the alternatives of a question, and how many answered each question. I have a table for alternatives called tblAlt and a table for answers from users called tblAnswers.
There are only 5 alternatives for each question. Is there a way to get each alternative, and how many answered each of them with one query?
This is what I made so far, but this is definitely wrong:
SELECT tblAlt.altText, Count(tblAnswers.answerID) FROM tblAlt, tblAnswers WHERE tblAlt.questionID = " & CInt(questionID) & "
