This is my first post and I'm not sure if this is the best place for this but I hope so. I am currently making my own very basic mp3 player. I have set it up to import songs and load their ID3 tags into a DataGridView. My problem is that I want to save these to a XML file. I know that I can easily save a DataSet to XML but I'm not sure how to convert my DataGridView into a DataSet or if there is another way to save it as an XML file.
View 3 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.

I've made a function to convert a number and fraction string eg. "22 7/8" to decimal. I've no problem pulling the data from the current row cell to pass through the function. Checked it via a temp textbox i put on the form. What i actuall want to do is pass it back to another cell on the current row. Tried a few things but having no luck. Here's the code of what works. The name of the cell i'm trying to pass the result back to is called "BaseDec".

I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

It would be easy enough to make my own system for this, but I'm figuring that the .NET library, being as massive as it is, probably already has a class made for this very purpose.For hit detection, my VB.NET game uses two 2D arrays that store the state of each pixel in the level. Each element in these arrays is a Byte (or, more accurately, a value of a flag enumeration type based on Byte).
Public TiHD(,) As HitDT ''//State of each pixel in the level based on
''// its underlying tile.
Public SpHD(,) As HitDT ''//State of each pixel in the level based on[code].....
I would enjoy being able to just give each sprite & tile its own 2D array of hit detection data (defining which pixels of the object are solid, dangerous, etc) that can be directly written to TiHD or SpHD at a specified offset.I'm willing to bet that .NET has a class that can do this for me.Presumably I would just have to pass TiHD or SpHD to the constructor, and then I would be able to use the object to indirectly modify the array with extended functionality (similar to using a Graphics object to modify a Bitmap). Is there such a class?

View 1 RepliesI am currently making an old school adventure game for a college project, it uses an Access database (dbGameStats) which has the primary key (gameStatsId) which is an auto number. The main form of the game holds the data bindings, dragged into text boxes, and the various screens of the game are shown over the top of the main form. So on the main form I have highscore and player name text boxes, bound to the corresponding database fields, when running the program, the user enters a name, the highscore field is altered as the game progresses and when the user exist the database is updated using this:

I have two files like this
File one

what i need to do is from file 1 let say my line is like this
[2 11.63 39.7] X7.705 Y0.735 209.037
Open -209.037
18N694 P321 117461, 50374 100MIL;
from the line i must take P321 and match with my File2 if i find the mathing line like this
12N709 11.3611 4.9474 P321 L6 BOTTOM 100MIL 43-CHISEL X11.3611Y4.9474 1922 0
then i must take the value beside P321 which is L6 and write it in my original file like this
[2 11.63 39.7] X7.705 Y0.735 209.037
Open -209.037
18N694 P321 117461, 50374 100MIL; L6
How we can do this. To get the P321 from my file 1 can i use regex pattern like this P*[0-9]. And how to match the regex pattern with file 2 write the content ?

I am kinda a newbie to programming. I am looking to switch a KVM switch via a VB (express 2008) program.Which would require me to write {SCROLL LOCK}, {SCROLL LOCK}, and {UP ARROW} out of the PS/2 port (or out of a serial port). I have tried using the Keybd_event function, but this is apperently not what the KVM is looking for. Currently I have the PS/2 port hooked directly to the switching port of the KVM switch and an additional keyboard plugged in USB (the computer has found both ports).

I am throwing up my hands here a bit. I am long time VB programmer that "scuttled the ship" and moved to VB.NET recently. I have purchased a small fortune in some good books and read large swaths of them. I have also watched numerous online video, Beth Massi, etc. I have learned quite a bit. But I am really lost when it comes working with SQL Server. Do I use bound grids? Do I use datasets? Why would I not use a bindingset? How do I iterate over the retrieved dataset, the list seems to go on an on. It seems far to complicated to me. So here goes. I have a form to enter a vendors info into. I want to connect to the SQL server and grab various fields on the form and perform an Insert. Can somebody show me simple straight forward code to do this and why I would do it this way vs. the other seemingly million ways. Also how about an Update call to (modify an existing vendor, I have a unique id I can query on in the table)? I can put in all the error checking (Trys) and such - its the connection call and gory details of this that seem to perplex me. I have recipe books that spend to much time on more complex things. I need simple.Also can someone recommend a good classroom training series for VB.NET in the greater Boston area.Learning from experts in person is best for me. I will be back later to ask about datagrids some.

View 2 RepliesI am working with a console application for VB 10.
How can I replace data that I have already written with:
Console.Write
Or how can I write on a specific point: e.g. 100 lines, 100 chars left
In the same way that a program such as wget has a loading bar that does not keep getting replaced every time progress is increased.
