I am developing an ASPX file to return all records from a SQL table. I can successfully get all of the numbers to show, but now I want certain rows to have their background colors changed if they meet certain criteria. So I want to compare 2 of my columns to some value, and if it exceeds this value then it should change color of that row. How can I fix below code? Main problem is I don't know how to specify a column of data to compare. No errors on this, but none of my rows have color changes either.[code]...

I have been trying to use a bit array as a dictionary key and even though I know each bitarray value is different the program fails with a duplicate key message when a try to add the second record to the dictionary. Is there any way I can make this work?

You can do this
Code:
Dim Test() As String = {"Stuff", "Stuff", "Additional Stuff"}
Is there a way to do that with a generic dictionary? Also, is there a name for that?

I am trying to deserialize a JSON string that looks like so: {'type':'clientlist','client_list':[]} I am using JavaScriptSerializer() to do it. For some reason the JavaScriptSerializer() is choking on the member 'client_list'. It doesn't give very good info. The error it gives is:

I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

I have written a small project that saves data in a data set, this part works fine, but I have some errors with the code I have written for importing excel data to the datagridview and exporting data from the data grid view.
This is a test project for me to learn how to do this stuff, so I will post the code for the entire project so you can see what I have done from start to finish.

I have some code below that works mostly in vb.net but when it gets to ExtHubPort and after it doesnt work i think i might have incorrect formatting of code somewhere or a simple error because if I get it the same sounds as the vbscript except when mouse device is plugged in it gives me this error in device manager: "device could not start error 10". Here is the code but to plainly put it the code just adds an emulated external usb hub to the system's hub and then usb device to that hub:

The msgbox's mark important areas that will help if you wish to debug this code. I have a codeplex page in which the project has the dlls for both 32-bit and 64-bit OS's but if you have the dsf runtime you can manually get them from the GAC (c:windowsassembly version and yes im sure because thats where i found them) and just paste into visual studios public assmeblies folder and it

I need help to form a code for a small arrays manipulation. The input data are known: they are two integers "N" and "s". An integer "N" is always divisible by 4.I need to create an array of "N" members, by repeating (N/4 times) this sub-array: 1,2,2,1 (always is the same). In the picture, this is shown in blue. Then I need to add the same array to the existing array, but shifted for "s" places (red array). The result is "yes" if each sum in new columns is always the same (3). Otherwise the result is "no." note there is no need to draw or display something (DGV, table ...). The required result is only "yes" or "no".

I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

I'm basically trying to do a small report card project. I only need to pull 5 Students with each student having 5 Test Scores a piece. The full Code of what I have for the submit button is below. I have actually 3 questions.
1. I always seem to have trouble with them unless I initialize them when I dim them. Is there a better way than below
2. The below code works really well for Student 1 and all 5 test scores. Rather than do that code 5 times though, what is the best way for me to basically state that IF dblStudent1(intMax) = 4 Then Change dblStudent1(intMax) to dblStudent2(intMax) etc.
3. Would this be better suited towards a multidimensional array ?
Private Sub btnEnterGrades_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterGrades.Click
Dim strStudentNames() As String = {" ", " ", " ", " ", " "} ' Holds the 5 Students Names
Dim intMax As Integer = (4) ' Place Holder for Student Number

I have the following object:
countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))
The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:
groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)
The best result I could get was:
Lookup(of MasterCategory, Dictionary(of Date, Integer))
From:
countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)
Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.
Current Code
[Category Class]
- MasterCategory As Enum
- Name As String etc

I am totally new to VB and ADO. I know that we can bind a data source to the datagrid view but if I want to populate the same datagrid view with different set of data but the column names are the same. Based on a date range entered by the user I would like to populate the datagrid view. Can we do this at design time? If I not how do I do this?

This error has me completely baffled. There is no indication (that I ca FinD as to what field won't handle the information. Heres the situation:I am using an Accees query to insert a new record in a table with 49 fields. Of these fields, 1 is an integer, 7 are booleans and the other 41 are text fields. The text fields represent either Time of Day or a Timespan.
My field sizes are:
For time of day 8 digits(example 08:00 AM)
For a time span 5 digits(example 03:30) I will never exceed 2 digits for
hours
I have checked every field in the dtatbase and they are all as noted. I am at a loss as to how to proceed.

Is it possible to use VB code to code an application that can merge Hex data from a small (50kb) .dat file with the hex data from another small (50kb) file? This would require designating specific offsets, which I can pre-program, but If I could have user input this would be preferred.
Example.
Hex_1.dat
00 00 00 00 00 11 11 11 11 11 (Offset = 5)
Hex_2.dat
22 22 22 22 22 33 33 33 33 33 (To offset = 5)
Result file
Result.dat
11 11 11 11 11 22 22 22 22 22

Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]
