I've got this problem of importing excel data to MySQL database. I want to create a VB.net application that allows the user to browse the excel file then click upload and automatically all the data in the excel file will be saved into the database.
View 1 RepliesI have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?
I am trying to retrieve the data from EXCEL 2003 spreadsheet from row 8 onwards because from Row 1 to Row 7 the row is merged columns from A1 to K1, A2 to K2, A3 to K3, A4 to K4, A5 to K5, A6 to K6, A7 to K7.

I created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.
View 14 RepliesI have a problem with importing an excel into a data grid.
Here is my code:
Try
Dim _Obj As New ExcelConnection.ExcelConnection
_Obj.ImportAttendence("c:Info_pc.xls", DataGrid1)
Catch ex As Exception
End Try
In the excel i have numers and text and "Service Pack", "Processor Speed" and "Numar procesoare(Number of processors)" and the values for these are numers. in the data grid when i import the excel those values doesn't appear, i receive the value "null".
how I get user details from a user table from a mysql database.

I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
So I have a text box in a form. The test box needs to take the value entered and insert it into a column within a row in MySQL. I know it's connecting to the MySQL online, I have a message box telling me so upon a successful connection. I'm just having problems adding the value. Here's my code: Public Class frmOptions Dim ServerString As String = "server=db4free.net; Port =3306; user id=dailylogmain; password=XXXXXXX; database=dailylogmain;" Dim SQLConnection As MySqlConnection = New MySqlConnection
Private Sub frmOptions_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I use to do programs in VB5 and haven't touch VB for years, and now i just started to pick it up again, VB2010. my problem is getting data from my MySQL Server (local)
i was able to create my Data Source successfully.. however, when i click and drag my CUSTOMERS table to my form the datagridview shows nothing. I read a few online tutorials and they all said that's all i have to do not working for me..i have 9 records in the table already but nothing is showing..
I have for ex. 5 names i table A in table B i have several rows with 50 names.. But i only want to pull out the records that matches the 5 names in table A! I never know the amount of names in table A so i need to pull out every record in that table..I guess i have to get the names from table A and put them into an array and then in the query get the records from table B that contains the data in the array.. I have tried, but no luck..

well this may be a simple question to some but for me, im not even sure where to start. I have never done a program in VB.NET yet that uses a MySQL database. So this should be a fun thing to learn. I looked at an example for access databases and it seemed pretty straight forward. But I must use MySQL as the database is on a Linux server in Ohio.
What I got so far is how to connect to the database using ADODB. Here the example I'm giving. You got 4 col's call AccountNum (primary key), Phone, Name, and Address. For each row is data of a client. What I'm trying to do: the program asks for the account number. You type in the account number of the client. It then
compares it to the rows of AccountNum col till it finds a row with it. Then it asks if you'd like to change the phone number or address.
So what I'm looking for is the, how to call rows and change data in col's.
I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.
