How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done
Apr 23, 2010how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
VB 2010 - Rank The Data - Divide The Data - Find The Median
Oct 14, 2010There are few steps to find out the half slopes of the graph.
Step 1: Rank the data The independent variable is required to rank it from the lowest to the highest.
Step 2: Divide the data Divide the sample size into 3 roughly equal parts, which is the lowest, middle and the highest parts. If n/3 has remainder of 1, +1 into the middle part. If n/3 has remainder of 2, +1 into the lower part.
Step 3: Find the median The size of each part = n, find the ((n+1)/2)^th value for both dependent and independent variables. If the ((n+1)/2)^th is not an integer, sum up the 〖n/2〗^th value and ((n+2)/2)^th value and divide the total by 2 to make it as median. The median, m1 for independent variable in lower part indicate as XL , middle part median, m2 as XM and the highest part median m3 as XH. For the dependent variable the median is indicate as YL, middle part as YM and the highest part as YH . Figure 3.2 Example of median m1, m2 and m3
Step 4: Find the half slope Find the half slope for the lower half, b_L=(Y_M-Y_L)/(X_M-X_L ) and for the upper half, b_H=(Y_H-Y_M)/(X_H-X_M ) .
Step 5: Find the half slope ratio, b_0=b_L/b_H . If the ratio is negative, the dependent variable need to add with a constant, c in order to make the slope same direction.
Step 6: Identify transformation. Depend on the graph pattern pick one type of transformation which is nearest to the original of the variable.
Step 7: New half slope Find out the new half slope ratio, b1 by repeat step 4 and 5 with the transformed variable.
Step 8: Repeats steps Repeat step 6 and 7 with choose the transformation which is nearest to previous transformation and find the new half slope ratio, b2, b3,�, bn. Repeating this step until |1-b_i |≤|1-b_j |, for i<j, i and j = 1,2,3,
Step 9: Result bi is chosen. The data transformation used in bi is the most closest to be normality.

May 11, 2011I am a co-op student learning vb.net and I have a project which retrieves data from an xml file within the program (based on selections made from combo boxes) and calculates and displays prices.[code]I have one combobox that loads data from the Processes section just fine, but then another uses the same method and gets an "IndexOutOfRange" error or "Column AB12345Bed_Size Not Found" even though I am using the same method for both. For "Processes" I am using DataView.Sort on "<12345Material_Process>" which reflects the selecteditem in the combobox. The program retrieves that row without a problem. [code]

VS 2010 - Get Data And Add It To Form
Jan 17, 2012Is it possible to get data from one column in one table (unique reference) search another table for all the enteries of it, Then display each unique reference then a total for it, and add textboxes based on how many unique references then total them?
So the first table would look like
Travel - Fuel
Travel - Food
Travel - Flights
Then in the 2nd table would be
Description Value Date
Travel - Fuel 30.00 03/01/2012 (jan)
Travel - Fuel 20.00 01/02/2012 (feb)
Travel - Food 10.00 01/01/2012 (Jan)
Travel - Fuel 35.00 05/01/2012 (jan)
And then display it
Description Jan Feb Mar Apr (and so on) Total
Travel - Fuel 65 20 85
Travel - Food 10 10
Travel - Flights
and add for a row each time someone adds a new description to table1.

VS 2010 Add New Data Source?
Dec 29, 2011Most of the VB.net windows application I have created so far have been working off a local server. To add a data source I click Add New Data Source and then database and then connect to the database by linking through an ODBC driver. This works neatly and places data sets that I can then pull onto forms in various formats, DGV's textbox, Combobox etc.
The application I am trying to build now links to a hosted server on the internet. For security reasons I cannot create an ODBC that connects to the database. I can use a ADO connection string and this is fine for various tasks and I know I can populate a DGV using this connection. However, it is much quicker once I have dataset that I can repeatley call on.
VS 2010 Checking Url To See If There Is Data
Jan 11, 2011I�ve written an app that downloads from the internet with my.computer.network.downloadfile mehtod. The problem is it�s supposed to try a numder of urls and if there�s data, it downloads, otherwize the url is wrong. The utl adress is a combination of date and a letter, which the program gets from a database. So for every date, it checks all the letters as suffixes until it finds the right one. However the wrong ones tend to time out or something, which takes forever and also causes some errors. Is there a way to check if a url is valid at all, instead of actually trying a download?

Jan 25, 2012This week I am doing a simple addition, multiplication calculator and am having a little problem clearing data and resetting the enter button. It is supposed to keep the add and multiplication buttons disabled till the user has entered two numbers into the list box, then you are able to choose between addition and multiplication. What I am trying to accomplish is once I hit the clear button the enter button becomes available again to enter numbers into the list box again and do the whole thing again.

I accidentally discovered that if I open the .csv in Excel and then save the file, my program will read it in perfectly.

Printing Data In Express 2010
Aug 2, 2010I'm trying to print from VB Express but it seems to be so difficult. I tried the printform component only to see the end result being blurred. I have data in one table (which will be used as the header) and data in another table (the body) which I need to print out. Seeing that the express edition does not have any reporting capabilities, I turned to several other open-source projects providing "free" reporting tools, such as MyNeoReport. MyNeoReport is acclaimed to be so good but the developer lacks a detailed tutorial for it. And the tutorial's I did manage to find are all in C#. Not helping.
How do I go about printing the data? The design is simple. Extract the company information from table A to display as the header, extract the body from table B to display as the results. I also need to calculate the totals of the body and add it to the footer or bottom of the report body. I can't seem to find any relating forums or questions similar to mine on any forum. Currently on the form, I've got a few labels, textboxes and a listview. I know I need to load the filtered data into a data grid at some point.
Is it possible to give me a detailed example of how to do this? I'm really frustrated with this whole printing thing. I don't have the finances to buy these other reporting products and the one's claimed to be free all comes with a price-tag in the small print.
