I already have a problem..
Im trying to get the soft recognize the timerange between times:
For example:
START TIME: 10:00
[Code]....
I need to pick the time range between 10:00 and 05:00 in the morning.
I tried both - SQL Select and Visual Basic - both options didnt work when I needed to pick the time range as above. Normal ranges during the 24 hour cycle where ok.
Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
View 4 RepliesI want to verify if the current system time falls within the specified time range between 7:30pm - 9:00pm. If it falls within the specified time range then display a message.

i have to make a little calculator, so far i can make all work, but i want to add 2 textboxes to convert the unit between 1 and 999 to "A" (ampers); 1000 and 999999 "KA" (kiloampers). Or for the resistor value, between 1000000 and 999,999,999 to "MΩ" (Megaohms)

I can split the text file easily, but this is the snag.
The text I need is within two [ ] and I want to find the text between them.
I have a datagrid, with an unbound checkbox column. How can I get a range select use shift and ctrl keys that will check the checkbox?The moment you check a box, it selects only that row, so the rows selected are down to just the row you clicked on. I've been playing with several events and settings and I can't seem to get it. Can anyone point me in the right direction?When your problem is solved, add (RESOLVED) to the end of your topic. This will save the guru's time and be able to solve more problems. Remove the question mark icon as well.
View 3 RepliesI would like to select transaction id based from its creation date. All transactions are displayed on form load event on a datagrid. The select function should be executed on 2 datetimepicker (the first should be the start date, the last should be the end date).So there are three controls on a form, 2 datetimepicker and a datagrid. I managed to load all transactions into a datagrid, and managed to select/filter those transaction based on id, but not date.the table is called 'transaction_details', it contains 'transaction_id', 'transaction_date', and few other columns. transaction_id is the primary key.

So I am basically asking the user for the file directory of the excel file, then I setup some variables (originally set at public as project variables, since these were being used and changed in other places). I have also added the lines to set these variables to nothing (just in case, I do not think that it should matter). I then set these variables to the excel file, workbook, and sheets that I want to access. [code]...

am using sql 2005 and vb 2008.i need to compare dates and select matching records betweem a selected date range.say records between 11/13/2010 and 11/20/2010.e.thing is working ok except when it comes to selecting dates between 11/1/2010 and 11/9/2010.this is happening because when am retrieving the dates from database,its being retrieved in the format 11/01/2010 instead of 11/1/2010 and so it reports no records found,and knowing the limits of sql 2005 this is the only way i can retrieve the date.

View 7 RepliesWith an excel file opened, i'm trying to:
Select a Range of Non-Contiguous Cells within a Column, then return the address of the last active cell.
Below, is what I have so far: Note the section maked:
' I can't get the next bit to work: '
To make it work, so far :(
1. Create a new Project using VS-2010.
2. By default, the form should be displayed as "Form1.vb".
3. Add a Label (No need to name or set anything).
4. Add two buttons (Again, No need to name or set anything).
5. Double click on the Form...
6. With the form code displayed, Select all, then paste the following.

I'm having a problem with my Access database.I have to select the highest ActieAantal before the last action ( )because the last action is always the sum (Totaal).this is a part from my table
Persoonid..........ActieAantal..........acties..........Actieid....... ...datum..........aantal..........totaal
.......... 3 ................ 1 ................... aa ................. 99 ........ 31/12/1975
.......... 3 ................ 2 ................... bb 94 ............. 98 ....... 31/12/1975 ........ 94
.......... 3 ................ 3 ................... cc 10 ............... 5 ....... 17/03/1989 ....... 10
.......... 3 ................ 4 ................... dd 20 ............... 2 ....... 25/08/2003 ....... 20
.......... 3 ............. 999 ............. totaal = 124............. 9 . . . . . . . . . . . . . . . . . . . . . . . . . 124
The next person also has some acties with corresponding Actieid and a Total when I use this query I alway get the 999 values
SELECT Register.Persoonid, Max(Register.ActieAantal) AS MaxVanActieAantal
FROM Register
GROUP BY Register.Persoonid
ORDER BY Register.Persoonid, Max(Register.ActieAantal);
but when I try to exclude the 999 value I get nothing
SELECT Register.Persoonid, Max(Register.ActieAantal) AS MaxVanActieAantal
FROM Register
GROUP BY Register.Persoonid
HAVING (((Max(Register.ActieAantal))<>999))
ORDER BY Register.Persoonid, Max(Register.ActieAantal);
find the highest 'ActieAantal' after excluding the 999 values?
Not sure if this is possible but can you use the select statements in VB to pull in from not just one but multiple tables and put the data in a gridview? [URL]

Ive got a web page so that the users select a day from the calendar and the date is input to a text box, the format is dd/mm/yyyy, it is the same format in the database table.
I want to select the data from the database when it is = the date in the text box but it is retrieving data in mm/dd/yyyy format. My sql is:
SELECT Booking.Date, Booking.RoomNo, Booking.Lesson, [NoComps] - " & students & " AS diff FROM Rooms INNER JOIN Booking ON Rooms.RoomNo = Booking.RoomNo WHERE booking.Date= #" & txtdate.Text & "# AND booking.Lesson = '" & lessonlist.SelectedValue & "' AND booking.Type IS NULL
how can i make sure it retrieves the data using the correct date format?
I need to filter a measurements table that consists of 63 measurement objects that may or may not be tested more then once. The entries are put in a Batch table on a SQL server in the following fashion:
ID: | Serie | Test object | Min Amps | Max Amps | OK?
DateTime| String | Integer | Double | Double | Boolean
So there may be multiple entries in my database with the same series and testobject number but with (slightly) different results.
Currently I just select: SELECT * FROM Measurements WHERE Serie = 'XXXX' and use a datareader object to fill a datatable and then I let loose a routine on it that will either: Get the last result that produced a good measurement, so OK = 1 and max ID. Or the last result that produced a bad measurement if there are no good ones. I then end up with a list of 63 either good or bad measurement objects with the last good result, and if there isn't one then the last bad result.
Now I know that SQL is quite powerfull and I suppose that it must be possible to directly query for these results without a programatical routine re-filtering the results. I suppose it's like Selecting within a select statement..
I am trying to use sql to select a row and then find the minimum and maximum values in the row, do some preprocessing, update the recordset using in visual basic 6.0, and then go ahead select the second row, find the minimum and maximum values again.. and go on, until the last row.
The problem is I am having difficulties using sql select for a ROWS.. I am aware how to do this for COLUMNS.. if I want to extract the first row from a recordset, find the min max values, and then, extract the second row and so on.. how will it be possible? (discouraged to use VBA, since i am limited to VB only)..
Here is an example of my recordset:
Code:
Col1Col2Col3Col4Col5
0.43530.05630.74350.92510.0325
0.28430.00320.82430.73250.9981
This example only lists two rows currently. I want to extract the minimum and maximum values from each row at a time, and then the second row. The reason for extracting minimum and maximum values is because I want to normalize my data in the range from 0 to 1.
Logic: After I find the min and maximum values for each row, I will use the recordset back, read the same row, and update every columns entry with my normalized data value... then proceed to the next row and do the same for every row in my database.
I have a stored procedure that I need to be able to change the table name that the select statement in the stored procedure uses depending on a user input, however I am having a problem with the code:

I am attempting to migrate from vb6 to vb2k8. My first attempt is a program with three forms. The first form extracts data from Oracle into a local Access DB. It works great but the second form only pulls data from Access to generate a text file. The VB6 version does it in 10 minutes, the VB2k8 version gets 1/10th through the data in two hours. It is hanging on:
"select sum(hrs) as thrs from tablename where emp_id_no='xxxxxx' and hours_type='CE' and org_ofc_sym='oos'"
I have to hide identifying fields but the emp_id_no and oos are correct.
