Importing A Flat File Into A Header And Detail Set Of Tables?
Mar 21, 2011
I have to read in several thousand lines of a EDI 4010 or 5010 formatted file into a database. This is medical claims data. In my current process I read each row of the file and parse it into a string array. I then assign each value of the array to a string variable and when I detect a new claim header or detail record I write the variables to the SQL server in a SQL insert statement. Example below
I'm getting this error 'column' argument cannot be null. Parameter name: column at the bold character instruction. Also I would like to know how to relate two tables with two key columns in each table
Dim connection As New OleDb.OleDbConnection(strTextoConn) Dim EnPartesdataSet As DataSet = New DataSet("Enpartes") Dim strsql As String
I am trying to create a datagrid and export the contents to a text file using VB.NET and I am doing this inside an SSIS script task in order to automate the process to export a dynamic table to text file. I don't get any error and the files are created but the files are empty. [code]
I do no know how to go about doing this. I have a view in the db. I have gatheredall the data in that view. Now when clicks a button, i want to transfer half column data in the view to header_table and the other half into the lines_table. Also once it is transgered, I want to display it in a grid view. This time all the fields from header_table and all from lines_lines. Can someone guide me how will I do that by an example of code that is not very complecated and does what I want to do?
I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code: Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1 AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
I've gotten the code I posted a few weeks ago working to export a tab delimited file. ([URL]) Now, I've already converted it from tab delimited to "tilde delimited." My goal is to import this flat file created as an EDI 850 Purchase Order. My ordering system rejects the file, yet it looks identical to other working files. My thought is the encoding / format is wrong.
There are a lot of master/detail databinding examples with detail form on the same window than the master, I can't find any example where detail is in a new window.
Using SQLDMO you could export a file to a flat file however this functionality is not available in SMO. From what I've read you need to use SSIS to accomplish this now. how to do this in VB.NET or C#?
I am in process of designing an architecture for an application. Following is the high level requirement.
1. The basic requirement is to convert a flat file into XML 2. The input flat file can have various formats, the delimiters, the data positions may vary. 3. The output XML format is predefined. There is a specification defined in a word format, which I think I need to define it as an XSL or XSD.
I am planning to follow some design pattern. Not decided yet. The architecture should be flexible to extend the input file formats and accommodate any changes in output specification.
I have a huge amount of data in flat-file format that I would like to validate with Visual Basic 2010. Basically the data is a text file with 300 comma separated fields and 500,000 records.
Any tips, sample code or examples? Are any .NET classes specifically geared for data validation?
As I have different validation rules for each field (some fields are dates, some are currency, etc.) I would like to store the rules away from the code (e.g. in an SQL database table). Has anyone seen this done before?
i have been searching the web for days and yet to find a clue on how to extract specific data from a flat file, i know how to extract all the data from flat file but not "specific data".
my problem now is that i need to extract a certain data out from a very very messy log file, what i need is to extract the decimal data right after "score=". it is in this format "score=1.938249".
for the decimal data right after "score", it is very random, there is no fix length to this. and also "score" does not fix in a specific position, it could be starting of the string or ending of the string of messy data.
just a peak on my messy data, "time 20:34 17/1/2010 vlog=0 C:d7ad45f396850c532ef0ccf0da48d80di386peisgh437 ipint=98.1857991 score=1.78495 event@&1.13845" "time 20:34 17/1/2010 vlog=1 C:Documents and SettingsDefault UserDesktop score=4.085651123 ipint=70.1578356 event@&0"
What is the best method to parse through a Comma Delimited .dat file? I am using VS2002 and VB. My code will be looking for certain placeholders within the files and pulling the value from that element to populate a table in SQL2000.Here is a sample of one row that is in the database so far:17768 01 1770 003 2009-11-01 00:00:00 5065.14 NULL NULLEach spaced section is taken from a part of the .dat file, but being manually keyed in for now. My job is to automate the reading of the file, and writing it to the SQL database.Here is a sample of the flat file I am trying to parse:
so i have a file that i need to read in vb.net. Each line is 32 chars long and each line consists of multiple fields. Meaning from char 1 to 9 it idicates ID then char 10 indicates an identifier,11-14 indicates a value field. I've looked at Readblock and it's not the tool for the job. Is there a way to break up each line into its respective fields other than just reading the whole line and breaking it up as a string?
I place these 2 questions in this forum simply 'cause those that know GDI+ best are probably .Net vs. VB6 classic users... So here it goes.I'm using GDI+ flat file to generate a textured brush with image attributes. Creating these are no problem, but I can't find documentation that says whether disposing of the brush will dispose the original image & attributes handles I've assigned to the brush or whether I need to destroy those also? I can't locate anything that says whether GDI+ copies the handles or uses the ones I provided. Destroying the handles well before the brush is destroyed does no damage. Thus my assumption is that the handles are copied. But you know what they say about assumptions.
2. Likewise I use a GDI+ function to return the image assigned to a textured brush. Again, I don't know if that returned image handle is to be disposed by me or not. The returned handle changes every time I call the function, so I'm assuming that I should be destroying it. Thanx to all that can shed any light whether from personal experience or pointing me to some black & white documentation.
I am looking at Visual Basic 2008 Step By Step. I need to read a flat file and insert the records into my SQL database. My code so far:
[Code]...
The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?
I'm trying to convert a DTS package to an SSIS Package. My package contains a Data Flow task that pumps data from an OLE DB connection to a Flat File destination.The data in the flat file needs to be arranged in a certain way (eg: spacing), So how do I do that? Is there any data trasformation tool that will help me achieve this? If so how would it be done?THE DTS CODE (to put things in perspective)
Our 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"
I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.
I have a listview set on 'Details' and its full of data. There's about 6-7 columns. I want to export certain rows if they are green and exclude the rest.
I wish to import data (into a text box) from specified tags within an XML file.[code]Instead of loading the whole file into a text box I would like it to load data within <ABC></ABC> tags.The amount of <ABC></ABC> tags varies for each XML file. As does their placement (which line they are on).
i am importing a csv file into my app. this is to let the users pull in info they have in excel.somehow, they have slanted apostrophes, and not tick marks. so when i open the file stream and do the import, it pulls in those characters as blank boxes (unknown char).
Is this possible? I upgraded to VB Express 8 and have several programs that I would like to import into VB Express 8 from VBE 5. But everything I have tried so far has not worked.....This is the first time I have imported files from one computer to another. I have tried to save the file as a zip file and unzipping it in VB 8, but that didn't seem to work.
I'm going through All-In-One Code Framework Coding Standards document and one of the recommendations is to add a file header comment at the start of every human-created code file. This is the first time I've seen such a recommendation and to me it's just an unnecessary and ugly clutter but I'm wondering if someone could explain why M$ recommends this?
I have a datagridview on my form with 7 columns and a variable number of rows. It's used to track stats on games (kills, deaths, assists, etc.) The way I ended up saving it was in a .xls file for the simplicity of being able to edit it in excel as well as my program. how to import the file back into the DataGridView though.
Here's the code I'm using the save the file:
VB.NET Private Sub exportExcel(ByVal grdView As DataGridView, ByVal fileName As String, _ ByVal fileExtension As String, ByVal filePath As String) ' Choose the path, name, and extension for the Excel file
I want to create a button that will open up a form that will be used to browse a filesystem and select an excel sheet to import into access. I'm a noob at .Net and I needsome help on how to do this.
