Datatables And Xml Reading - Fail

Jan 7, 2010

I am working on a mdi project and I have a few different xml files that I need to read in and I would really like to use multiple datatables, but only one dataset. I have always struggled to get a datatable.readxml(filename) call to work without an invalidoperationexception b/c of the schema stuff. I don't understand it very well and in the past my workaround was just to make another dataset. I am trying to avoid doing that from now on. I have written a routine called readxml which will take a xml file name, xml schema file name, and a datatable name and return to you a populated datatable..but I can't get it to work.

Here is my call to the read xml method (comes from my main mdi form class during form load)

Dim dt As DataTable = globals.xml.readxml("SqlConnectionString.xml", "SqlConnectionString.xsd", "sqlConnection")

Here is my readxml routine, I will post two versions of what I tried attempt #1: use a string of raw xml and a xmlreader

VS 2010 Reading Chars From A String?

Nov 11, 2011

still pretty new to programming in general, but I have most of the basics figured out.I stumbled across this problem today, though. I wanted to try making a simple encoder/decoder. However, I am having trouble getting characters from a string.

I have a list(of char) to separate the individual letters in the message (letterList), and textToConvert is the text that the user types in to be encoded. Here's the section of code my problem exists in:

For i = 0 To textToConvert.Length - 1
letterList(i) = textToConvert.Chars(i)
Next i

Upon running my program, I get an out of range exception for the middle line above. Am I doing something wrong?

VS 2010 Reading Raw Text (?) As String To Manipulate?

Feb 29, 2012

I am not sure if this makes sense or not,but I need to process raw text(without any encoding?) that I retrieved from a file recovery application "PhotoRec"
With an application like Notepad++ I can see all of the text I need to manipulate but with VB I seem to only get some of the text with other stuff stripped out.Here is what I am using to process the file:

[code]...

I essentially add each line of text to the collection so I can read each line at a time (other processing, etc.)So, as mentioned, with the above code I get text but not all of it. With different encodings I get different versions of the text represented in "currentbyte".So, how can my .NET application read text like Notepad++ or a similar "raw" text reader app?

IDE - Upgrade To 2010 Projects Referencing A Class Library Targeting A Different Framework Fail To Build

Aug 18, 2010

Say I have a Framework 4.0 project that is referencing a class library targeting 3.5. The project will simply not build. It won't give me any valid error message it will just act as though the reference does not exist.

Projects that were working like this in Visual Studio 2008 are no longer working in 2010. Took me forever to figure out what there error is. If I remove the project reference and add it back the intellisense lights up and you can tell a variable referenced in the class library is found. But as soon as you build the project everything is lost. My using statements get underlined, references to the variable all turn grey and project fails to build saying the class cannot be found. Once I make the class library 4.0 as well everything builds. I get the same issue between 4.0 client profile and 4.0 as well.

Dynamic/string Reading Calculator?

Nov 12, 2011

I'm making a calculator that would read a "string" from a textbox and parse it and follow Order-of-Operations/PEMDAS on the string. I have a couple of questions:

1) What would be the best way to parse the code so that it won't just take a "left expression" and "expression" and perform the operation on those 2.

2)How would I be able to make is so that 0 is considered valid, but prevent a 00 or 020 or 002 to be inputed.

Reading String From Process Address

Aug 20, 2010

This code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.

Reading Individual Lines Of A CSV Into A String Array?

Mar 11, 2010

It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on.(I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.

It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:

Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()

[code].....

But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array.

Reading String From Process - Cannot Return Variants

I have the code below (found on forums) that should read the string "34,56,23,74,69" starting from the first address of another process till the end. However when I start the project I receive this error :"PInvoke restriction: cannot return variants." With Search Engine for example, the string is found, displayed and changed without any problems. Right now I have a subroutine that searches the string but only if I put the right memory address, and unfortunately the address changes almost every day.

Asp.net - Reading CSV File With OLEDB Ignores First Line Even With HDR=No In Connection String?

Jan 4, 2011

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)

The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:

Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")

[code]....

The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.
