I am trying to write a class to serialize/deserialize something as simple as:
<table border="1">
<tr>
<td>row 1, cell 1</td>
[Code]....
I just can't get it to serialize to this thing. I tried to generate the class using xsd but that produced a lot of garbage code and I really would like to maintain this by hand as it is easier than the monstrosity that xsd produced which didn't work anyway.
I am trying to read in an XML document, add a record with a tag for the filename and write to a different XML document.I have been told I must use serialization.
View 2 RepliesI have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?
View 1 RepliesHow do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...

Is it possible to serialize and deserialize a structure?
I think it isn't because the code I use will not work for a structure but it does work for other data types like an array, string etc

I have an ArrayList in android that I'm trying to convert to a Base64 String, then passing that to a wcf service though JSON and the wcf service inserts the string into a database. Then I need to be able to read that from the database and deserialize it in a .NET application.
This is how I am serializing the ArrayList in android:
private String convertByteArrayToSave(byte[] b){
if(b != null){
return Base64.encodeToString(b,0,b.length,Base64.DEFAULT);
}else{

The ultimate goal is to be able to be able to create a list of these shapes in the .NET app or android app and be able to read the list in the .NET app and android app no matter where it was created from. I'm able to it when you create the Shape from .NET and read it into android using WCF but creating it in android.
I have a question about serializing a Picturebox and it's child controls. I have a picturebox on my main form where a user can put new Picture boxes in.To a add a new Picturebox I say: Pictureboxmain.controls.add(Picturebox)But now I want to serialize this in a stream of bytes.

I'm trying to serialize a data table in vb.net:
Dim dt As New System.Data.DataTable
and for the serializer:
Dim js As JavaScriptSerializer = New JavaScriptSerializer()
dim jsonString as string
jsonString=js.serialize(dt)
when it serialize the data table on the last line,it got an error:
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Web.Extensions.dll Additional information: A circular reference was detected while serializing an object of type 'System.Globalization.CultureInfo'I even make the simplest datatable with only 1 column and 1 row, but it just won't serialize it?
If a class is serialized and has events fired from it that are handled on a form you get the error "Form1 cannot be serialized" in c# you can use (to work around this):

I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.

View 1 RepliesI have a html text file and I am trying to remove any HTML tags in tables, i.e. remove any HTML within THE <TABLE> and </TABLE> tags.
However, what's really weird is that the regex that I use, (?<=<table((?!</table).)*)<(?!/table)[^>]+>, works perfectly in PowerGREP or EditPad Pro, however, when applied in vb.NET (or Expresso) to the VERY SAME text, it does NOT work! I just use a simple replace method: newString = Regex.Replace(oldString, "(?<=<table((?!</table).)*)<(?!/table)[^>]+>", string.Empty, RegexOptions.IgnoreCase)?
Below is the example text:

View 6 RepliesI'm currently creating a HTML editor using a WebBrowser control and using IHTMLDocument2, but I'm currently having a problem that when I insert a table the user is unable to resize the table columns by dragging the border.
I was wondering whether anyone had done anything similar using IHTMLDocument2 and how I would be able to allow for the user to resize the tables like that. Or if anyone knows any good HTML editors that are written in VB.Net and are open source, unfortunately this is a requirement as I have to do some custom stuff for my customer.

My question is a combination of VB.Net creating html code..No Google links to pointless areticles in languages that are not VB.NET, please. If you cannot code it yourself, please don't reply because it's so annoying to ask a question then get pointless, timewasting links just so you can get your points score up.I have a table which has 3 columns - nothing special just simple but its's the row number I am having issues with. Will explain soon.There is a directory with jpg files in it and the number of jpg files increased yesterday by 67, today by 37. Because the picture files come with any filename I have created a Windows app that renames the new files taking the ending point of yesterdays number as the starting point for today..So, each row holds 3 jpg files therefore 67 jpg / 3 = rows (yesterday). First number today is 68. I type 68 into the app I created, enumberating & moving (renaming) the jpg ('hduyhdgu.jpg becomes 68.jpg, suhdos.jpg becomes 69.jpg and so on for each of the new jpgs in that directory. That is done by the simple FileInfo/DirectoryInfo classes. Whilst renaming the photos in numerical sequence it has to write the html in the following form: [code] My Questions are:
1) How to sort out the row numbers so they flow in groups of 3 correctly and not 70, 71, 72, 71, 72, 73, 74, 75..?
2) How to create the table in code that dynamically draws itself with 3 columns (200px each done by CSS) wide and enough rown to hold every jpg in that directory? So, if I moved 5000 jpgs in that directory tomorrow the code will loop through and create the html.
3) If creating the table dynamically as in Q2 above how would I fix the place to draw it? Placeholder? A div is easy (<div 'id="MyTable" runat="server"></div>. In code behind: MyTable.InnerText=.../MyTable.InnerHtml=...) but is it the best idea? [code]

The problem I am having is that It pulls out the 28,900 fine but I need to pull the rest of the information IE the 23,132 and the 170,000 and they will get placed into other Labels. Now they are not Static numbers they change all the time to higher or lower lumbers.
