I'm dealing with the dreaded <Run/> in Silverlight 3 and having to programmatically create a <TextBlock> and its inlines:
Why dreaded? Because it doesn't work, I guess, the way you'd expect. Exhibit A, below, should produce BARN (with fancy colors for each character), but instead it produces: B A R N
EXHIBIT A
<TextBlock FontFamily="Comic Sans MS" FontSize="88">
<Run Foreground="#A200FF">B</Run>
<Run Foreground="#FF0000">A</Run>
I have one class with <Serialize> attribute called Tree. And Tree class has an arraylist of TreeNode classes. Is it possible to use Soap to convert the Tree class and arraylist of TreeNode classes to one xml file or binary file? If it is possible, do i need to use <Serialize> attribute on TreeNode classes too? If not, what should i do then?
How best to manage multiple dat files for serializable objects of the same class. If one of my data files goes past a particular size, I want to create a new file. I then loop through both files when I do processing. Is there any easier way to do this and what's the best size to do this at in terms of performance?
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 populating an XML structure (using VB.NET) to pass to a web service. Here is how one piece of the structure is filled, and the rest of the structure is filled in a similar manner:
Private Shared Function GetSpecialties(ByVal specialties As System.Data.Linq.EntitySet(Of Provider.provider_specialty)) As XElement Return _ New XElement( _
[code]....
Some pieces of the structure can contain up to 30 elements. Each record takes about .1 seconds to create, and it needs to create about 35,000 records, so the whole process takes about an hour.Is there a quicker way to fill an XML structure like this?
In VB.NET I can easily embed strings into XML literals using <xml><%= "my string" %></xml>. How can I embed an XElement instance? I know I can use methods on the XElement, XNode, etc classes, but I'd like to do it in the XML literals if possible.
I have a need to merge two XElements with one taking precedence over the other, to become just one element. The preference here is VB.NET and Linq, but any language would be helpful if it demonstrates how to do this without me coding to manually pick apart and and resolve every single element and attribute.For example, let's say I have two elements. Humor me on them being as different as they are.
Notice a few things: the height attribute value of #1 overrode #2. The hand attribute and value was simply copied over from #1 (it doesn't exist in #2). The startinglineup attribute and value from #2 was copied over (it doesn't exist in #1). The Position element in #1 was copied over (it doesn't exist in #2). The Idol element value in #1 overrides #2, but #2's attribute of confirmed (it doesn't exist in #1) is copied over.Net net, #1 takes precendence over #2 where there is a conflict (meaning both have the same elements and/or attributes) and where there is no conflict, they both copy to the final result.
I am working with VB 05 Express, and I know C has this, but I want to comment multiple lines of code, without always having to put the little ' symbol on ea. line. Like, I think C has something like this-
.Basically I'm trying to code a program to output class names for a game which then allows the user to copy and paste the string of class names into the game itself.The template for class names in the game look like this ["name",quantity];So in the code for btn_add I have (which outputs to a text box):[code]How can I change the ' into "s without VB.net throwing up errors?

The web service returns 6 items per array. If the array return 2 sets of array (12 items), then i have to split it into 2 pages. how can i do it?
Example scenario:The web service should return at least 6 items(1 array)
example data *redemption date *reference number
[code]....
if i have two sets of these, then it should be printed on different pages.
I'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this: [code]If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.
I am attempting to remove information from an html file, using known 'tags' (not html tags, just short sequences that only occur where my information is). My code worked fine until part of one tag was on a seperate line. Here's the function I have been using: (OriginalString conatins the HTML file)
This is one of my first steps into the magnificient world of visual basic. I looked on many forums, but most of the time the questions asked are much more complex than mine. I am looking for a piece of code for the preparation of multiple graphs in excel 2003.
I need to add this line to a text file that is going to have other information added to it several times. I also need to add this line and have the number change every time the additional data is added.
i notice that when i start next line of code and i press enter, it recompacts itself and the continued line moves left a bit... then if i place focus on the second line and press enter again, it (the second line) moves to the left some more, and it keeps doing this every time i focus on second line and press enter. how can i make it so that my second (and third etc) lines are formatted in a pre-determined way so they are always a certain amount of tabs indented to the right from where my line 1 starts?
I am making a basic form that has 1 button and a rich text box.I need to click on the button and have it call a random line from 3 text documents (so 3 lines total) and place them in the rich text box, each on a different line.

i need to code a program to help me in my everyday job, i own my own business and this will help me with my sales. its a very simple program, and i cant figure out how to get my multiple textboxes to write to a new .txt file. i can only get it to do 1 line at a time. I have textboxes. named txtDate, txtCarrier, txtLocation, txtDateEmpty, txtDestination, txtQuote, txtPhone, txtFax, txtEmail.I want the "txtDate" textbox to be autofilled with the current date and time of the user input, which is started on the next textbox.the rest of the textboxes are going to be user input. then when the user is done entering data into the multiple textbox's they would click a button "add" or something to that sort.then those text box entries including the "txtDate" would be written to a new .txt file.in this format, Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email "all on the same line.and when the "add" button is clicked, the multiple textbox fields clear all the data previously entered.and is ready for another user input.
after the 2nd set of user input is entered, and "add" button is pressed,it would add(append) another line to same txt file previously written. example: Quote"Date - Carrier - Location - DateEmpty - Destination - Quote - Phone - Fax - Email " "Date2 - Carrier2 - Location2 - DateEmpty2 - Destination2 - Quote2 - Phone2 - Fax2 - Email2 "
then the previously filled text boxes would be empty again, and ready for input 3. and with this you would be able to add countless lines over and over of user input.ok, also when the program launchesI want a msg txt box to pop up and ask. "Where is the Load Origin?" then the user would input data and click enterAnother Msg box would pop up and ask "Where is the Destination?"Next "Pick Up Date" then "Deliver Date" and last would be "Notes" and all that data that was entered into the msg box's will Be at the top of the txt file like a header .
Using VB.Net I'd like to be able to replace a range of characters in a string in a single line of code.
i.e. something like

I'm using VB.Net to launch multiple command line window (same exe file) through Process.StartInfo. I would like to have those windows running at background without hanging main UI thread that launch them and at the same time able to get the output of those external window to show progress at progress bar.Here is a summary of what I'm trying to achieve but need further advise which way is feasible
- launch multiple exe command through Process.StartInfo
- don't want the external exe to hang my main UI thread
- need to get feedback from external exe to update progress bar which is placed at main UI thread
