What's happening is that the data is always being overwrited. I mean there is only one row which is constantly being overwrited

I've rendered a simple rectangle for the background and a bunch of star polygons randomly placed across the form. On the form is a picturebox component which I can move around, but for some reason it overwrites the background and stars when it passes over them. Could someone please explain what is going on there? I've tried performing searches, but have been unsuccessful in finding anything useful.
View 4 RepliesI need to create an application, which it connects to a IBM AS400 ATL to query LTO3 tapes that have expired and to be returned back to the datacentre. Tapes that have data written on them and not expired will need to be sent to an offsite location. Even if not an application, possible a script to do so.A email from the server will report the tapes require to go offsite and which tapes came be returned which can be overwritten with data again.
View 4 RepliesI have some conditionals in my InitializeComponent which affect the layout based on some variables. Unfortunately, it seems like whenever I rebuild my application, this code is reverted back to its previous state. Is this code being regenerated based on the Designer interface? Is there a way to prevent it from doing this?

is there a way to keep the settings stored in My.Settings from being "reset" during an upgrade installation? Every time I put out a new build of any application using My.Settings the settings in My.Settings are reset to whatever they are in the visual studio designer.
View 12 RepliesI'm trying to access 2 tables within the same DB in Access 2007, but I have a problem when saving information to one of the tables, I can do it with one table but when I try to save the information to the second table the data gets overwritten, not sure why, because I use the same procedure for both of them, just changing the variables to avoid mixed data, this is the code that I use to connect with the DB and fill the DataSet:
Try
dbProvider = "PROVIDER=Microsoft.ACE.OLEDB.12.0;"
dbSource = "Data Source=.\Almacen.accdb;Jet OleDB:Database Password=Slackware"

Again, it works fine when saving info to one table, but using the exact same procedure (with different variables) saves the new data but overwrites the previous information
I have make a Tabbed webbrowser. Browser is working fine. but when ever I navigate a page titles of tabs does not changed but overwritten as shown in picture there is on second Tab Text is overwritten. I am using this code for tab title
tabs_bowsers.SelectedTab.Text = CType
(tabs_bowsers.SelectedTab.Controls.Item(0),
ExtendedWebBrowser).DocumentTitle
And this for window title
Me.Text = CType(tabs_bowsers.SelectedTab.Controls.Item(0), ExtendedWebBrowser).DocumentTitle & " - My Browser"
I want to make my tabs to change title as in firefox titles changed, no overwritten.

how 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.
There 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.

View 3 RepliesIs 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.

The only thing that I can think of is that the database I'm using is an excel sheet converted to access.
Most 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.
I�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?

This 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.
