Read CSV / TXT File Into DataGridView
Jun 18, 2012
i need to read a CSV (txt) file that has no header and has 4 fields (all numeric), the number of lines will vary. [Code] I want to read this file into a DataGridView for proofing and later insert all these lines into an Access db with 2 additional fields added. I've been able to access, read/populate the CSV file into the Grid (code below) but I have the following problem(s): If I set the 4 column headers and other parms of the Grid at design; my sub inserts 4 more columns when it reads/populates the Grid. OR If I don't set the Headers and Parms, it reads the first line of the CSV into the Grid as Header info. [Code]

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.
Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?

I have a fairly simple XML file that I just want to read the data from.
It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file
File looks similar to the following:

I read a few relevant post about the procedure to create the Read function, but in my case, i would want to read the database with selected item only. Belows are the information of my form.
I have 2 DGVs and 2 buttons is my form.My 1st DGV is filled by 3 fields from my Excel Sheet: No, ProductID, and Quantity.there are 5 fields in my MsAccess Database: ProductID, Selling Price, Product Name, Selling Cost, and Supplier.My first Button is clicked to fill the 1st DGV with 3 fields.
Now my question is:
How can i compared and displayed the Selling Price and Product Name fields of the ProductID in the 2nd DGV? i.e: if only 2 ProductID is loaded, then only display the selling price and product name of that 2 ProductId only.

I have a datagridview that is bound to a dataset by dragging it onto a windows form. I want one of the columns on the datagridview to be read only for existing records (rows), but I don't want it read only when the add new icon is pressed on the navigator. How can I tell when a row is being edited as opposed to being added?

I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)
For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1
range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id
range.Text = range.Text & CHR(13)
Next icounter
It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?

I am trying to edit (in Visual Basic Express 2008) the source code of MapWindow's CSV to Shapefile plugin url... to read directly from a datagrid view. My datagridview is successfully created with the following code in frmMain:[code]With the help of BackWoodsCoder I was able to add the datagridview column names to the X and Y combo boxes but that's where I get stuck again. The original source code appears to re-read the delimited text file instead of using existing object code.I did try the MapWindow Forum first but have had no response thus far.

With my datagridview I have column for datetime. I used the following for format.
Mydatagrid1.Columns(3).DefaultCellStyle.Format = "dd/MM/yyyy"
But the problem is it's getting input like MM/dd/yyyy and after pressing enter it's changing to dd/mm/yyyy style. So is it possible to read input like "dd/MM/yyyy".

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

I need to implement a routine to read a plain text file, BUT that file has a predefined format.The file format is as follows:
Quote:
<FILE_PROPERTIES> 'The "< >" also appears
Propertie1="String" 'It's possible to have spaces after or before the "="
Propertie2="String"
Propertie3="String"
PropertieN="String"
[code]....
Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.

Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):
