[2005] Passing CurrentField Of From A TextFieldParser?
Feb 13, 2009
The following is a text file of 4 lines delimited with (,) making 8 elements and 1text string making 9 eliments in all.In my Environmental dictionary Environment and Conservation, Devoid of life non-biological.The Oxford University Physical and Theoretical Chemistry Laboratory definition says free of biological organisims. Does this mean the water in a pond is not abiotic but pure water is?"The following from the MSDN help that works:

I am using the TextFieldParser to read a 3rd party .txt Tab Delimited File Sometimes the file contains duplicate column names and subsequently I cant create my DataTable.
How can I check for duplicates first and change the name of the duplicate fields so I can populate my Table?
Example:
I have two columns called ST and would like to Change of of them to ST1 or something similiar to populate my table
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)
myReader.SetDelimiters(vbTab)

I'm having trouble passing an array of a user defined type to an procedure in a COM DLL. The prototype for the procedure i'm using is this:
HRESULT STDMETHODCALLTYPE GetData(
/* [in] */ DWORD dwCount,
/* [size_is][out][in] */ CSimData *puData) = 0;
CSimData is a structure which is also defined in the interface.
I'm trying to call it with the following code but am getting an exception:
Dim temp(1) As MACHPLANTSIM18Lib.CSimData
temp(0) = New MACHPLANTSIM18Lib.CSimData
temp(1) = New MACHPLANTSIM18Lib.CSimData
[code]....
The exception i'm getting is "COMException was unhandled - Exception from HRESULT: 0xC0000005" It looks to me that the array isn't passing properly to the COM function. I'm able to send a single object, but when I do an array of objects I get this exception.

I have populated an array.
Button1 click event
Dim array1 (3,3) as string
array1 (3,3) = "BLA"
End Event
Now, in the same class, I have another button.
When I click on this button2, i want to use this array to stream files to textfile.
The problem is that I cannot pass data from button1 click event to button2, as I have to declare the array again, and that causes array to lose data on button2 click.
If I however, declare array on top of class, I get a funny error sying out of index range etc.

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.
Public Sub printReports(ByRef trn As ITTransaction, ByVal blnPreview As Boolean)
Dim intSelectRptCnt As Short
Dim intI As Short

From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated
Dim btn As New Button
btn.Name = dgv.ToString()
btn.Location = New Point(0, 0)

I am working with some code that uses array lists and I am using some of these to pass data back and forth like this: whatFile = (sideLookUp(x)) and its working, BUT when I turn this code into a sub/function then I call it I get problems, like double to string errors, even though its all set to double.

I have a textbook loop using a TextFiledParser, which terminates when EndofData is trueTrouble is it's true prematurely. There is a knowledgebase article which decribes the issue perfectly but it only applies to V3.5. I'm using V4.0.I can't for the life of me see anything wrong with the data file, or the code. I reluctantly

It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

I am trying to use the TextFieldParser in windows 7. I have tried running visual studio 2008 in elevated security mode but i still get file not found. I have tried it on my XP machine and it runs completely fine.am i doing something wrong or is it that windows 7 doesn't like to give access to the filesystem?

I have this in VB6
Private Sub LoadDaysOfMonth(pintWhatMonth As Integer, pctrlWhatControl As Control)
Dim NumOfDays As Integer

Select Case pintWhatMonth

It works just fine if I use pctrlListBox As ListBox or if I use pctrlCombo As ComboBox, but I need to be able to use both with the same routine.
(PS: Yes, I do have a leap year check in here which I took out as it is not germine to my translation problem.)
(PPS: Using a control such as the monthview or datepicker is not an option.)

in my form, i have a textbox in which its visible property is set to false. this textbox is bound to my table's primary key column.
whenever i try to add a new record, it automatically generates a value and i can see that when the visible property is set to true. now when i set it to false and do a messagebox.show(textbox.text), it shows no value. so i set the visible to true and then the messagebox does show a value.
i don't want this textbox shown in my form but i need to get the value from the textbox when the primary key value is generated.
how can i do this without showing the textbox?

how I can pass data from my VB form to InfoPath?
I'd like to have a link on my VB form that will open an InfoPath Form with some information already pre-populated (name, date, etc.) with information that is already filled in on the VB form. I'm pretty sure there is a way to do this, just haven't figured it out yet.

I'm currently busy coding a hangman game in VB.NET.As a wordlist, I have a textfile containing 1520 words, each one seperated by a new line. The best I could think of to get a random word is with a Randomize() function. Then getting the word from the line # which was randomly generated.
[Code]...
Is there any better way for me to extract the word from that random line? If not, what would be the delimiter I should use for this and how do I quickly change the breaklines into that new delimiter without resorting to Office?
Also, how can I use the textfieldparser to get the file from resources? When I tried using my.resources.filename instead of "filepath", it gave me an ArgumentException due to "invalid characters in the path".

Ok so I am taking jm advice and using TextField Parser instead of ADO.net to read my delimited files and then build my own datatablesFirst question is how would I query the data?I need to be able to have two tables, one with sold propertys and one with propertys still for sale.The table I created thus far has all the records, the problem and my second question is how do you allow for a null value ?If one of the records isnt Sold then it won't have a Selling Price therefore when I set my datacolumn to be of System.Integer type It is not accepted

i'm not 100% sure about sql server but i think it doesn't accept null value for date type columns but in oracle, a date column can accept a null value. and since i'm using oracle, this is causing some problems because in my form, a textbox item bound to a date column will not accept a null value. reading thru some threads, it would seem that it is not possible to pass a null value to a date type in .Net.

I've got a program where the insert/update SQL was created with the values coded directly into the SQL string. I've changed this to use the Command's Parameters.AddWithValue method and all worked well. I'm now in the process of separating the data access code out into it's own class. I've got the Select code working using a DataSet in the form that I pass ByRef to my data class so it can populate or refresh it. My sticking point is in how to pass the parameters for the Insert/Update commands to the class since from the form I no longer have access to a Command object. Do I need to make the Command object in the data access class available to the form?

I'm using the following code to read some values in from a tab delimited text file:
vb.net
Using Parser As FileIO.TextFieldParser = My.Computer.FileSystem.OpenTextFieldParser(LogFile, vbTab)
Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String
[Code]...
As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.

Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
Here is the code:

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?

I am using VB.NET's TextFieldParser (Microsoft.VisualBasic.FileIO.TextFieldParser) to read a delimited file. However, when I try to read in a field with consecutive newlines within the field, the consecutive newlines are turned into a single new line. I would like the consecutive newlines to be preserved, but am unsure how.Here's an example file that I am reading in with exactly one field. The quotes are part of the file's content and there are three newlines (including the two consecutive newlines following line 2):
"This is line 1
This is line 2
This is line 4, which follows two consecutive newlines."Here is the code that I am using to parse and read in the file:
Dim reader as New Microsoft.VisualBasic.FileIO.TextFieldParser(myFile, System.Text.Encoding.Default)
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")

The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.

I am learning to use TextFieldParser to read a fixed width text data file. It works great. I copied code below. Question: How to stop at the end of each line because I need to add some code?

tf.SetFieldWidths(60, 30, 20) //three columns

I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:

The TextFieldParser is returning

I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.
