View 2 RepliesI have been using this code, see below, to try and write data from the DataGridView to a text file. It works but it puts an extra comma after each line and thinks that there has been another line so puts an extra 4 commas on a new line. So the text file looks like this:
9,Here to There,1,15,
8,Hell to Heaven,16,34,
I'm looking for any help for a way to get rid of the extra commas or an entirely different way of doing this whole process.

We are creating a VB program for school to collect data on student attendance and populate it to a table. I have all of the 'GET' statements but am having trouble creating the 'Insert' procedure. This is what I have so far. The form being used to fill the table has 4 items being recorded. 'Present' radio button marked as present, tardy or absent; StudentId, PeriodId and date. Not sure if we are on the right track. The target table is tmAttendance. There are approximately 25 rows of data on the input form.

View 1 RepliesOur application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"
View 1 RepliesThis task is a little out of my reach so i dont even really know where to start...I want a user to click the command field "select" in my gridview. I then want them to be redirected ( response.redirect()) to an input form that will have its various asp.net text boxes filled with data from that selected item.

IF the form is loaded from user
selecting item in gridview THEN
''Populate controls with data from selected gridview item Else Load

I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure).LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure.When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure,populate the structure from the data file, then call the method to transfer the data back to the website.
How do you recommend I transfer (copy) an instance of a structure from one .NET program to the VB.NET program that executed it?

View 3 RepliesI am using vb.net in my project. I have a datagridview bounded to a datatable m_table which has a column called Price_Change with decimal values. I want to display text in datagridview in green if price change>0 and red otherwise. I cannot simply use the following formatting because the bounded data table m_table is constructed in my code, not directly through data base.
DataGridView.Rows(0)Cells(0).Style.ForeColor=COLOR.BLACK
Code looks like
Dim rowText As DataRow = m_table.NewRow
rowText("Price Change")=10.00 'assign values to price change column
' there is no color formating for data table I wonder if cellformatting event can be used for this purpose. Would it slow down the load of datagridview? [URL]
I have a textbox which is part of my program and when I input data to the text box it fills the database with the data the way it is supposed to. I navigate through the data and the textbox show all the data from all the records I input. The problem is when I close the program and reopen it the textbox is empty for the first record. When I run a report or look at the access data base the data is there. If i navigate and go to the second record it shows the data for second and all the others the way it supposed to in the textbox.
