If I want to grab a DataRowView I use:
DataRowView arrangement = (DataRowView)BindingContext[debtorDataSet, "Debtor.FK_PaymentArrangements_Debtor"].Current;
How can I get a DataRowView for the previous position without changing the position to do so please?
|
|
|
|
|
BindingContext[debtorDataSet, "Debtor.FK_PaymentArrangements_Debtor"].Position will give the current position. Get the table from debtorDataSet and take the row at position - 1.

Hi all,
Is is possible to add the result of two anonymous LINQ queries together (when the data is gathered from two different data sources), to form a variable that one foreach loop can iterate on. For example:
var query1 = from x in dataCollection
select new
{
name = x.Name,
surname = x.Surname
};
var query2 = from x in xmlCollection
select new
{
name = x.Name,
surname = x.Surname
};
foreach (var result in .....
Many thanks in advance,
Kind regards,

hi,
i have many text boxes on my web page,
how can i get which text box is focused.
Thank You
|
|
|
|

foreach (Control c in Controls)
{
if (c.Focused)
{
MessageBox.Show(c.Text);
}
}
Remember to check if it is a TextBox, as buttons etc can also have the focus.

Have you had a look at the TexBox Class[^]?
Maybe you can find something there...

Something like this should work:
foreach (Control ctrl in Page.Controls)
{
if (ctrl is TextBox && ctrl.Focused)
{
((TextBox)(ctrl)).Text = "FOUND YOU!!";
}
}

Controls have an event that's triggered when they get focus, so you could just hook into this on every control, and store the last focused item yourself

You would probably get better responses on the Web Development Forum, but for what it's worth in Windows Forms there is the ActiveControl property. Is that also available For ASP?

I want to know how can I retrieve the GUID stored in the Assembly Information in the project properties using C#?
|
|
|
|
|
using System.Reflection;
Assembly asm = Assembly.GetExecutingAssembly();
Console.WriteLine(asm.GetType().GUID.ToString());
Cheers...

Unfortunately, the previous solution is highly unlikely to work. However, you can find a small snippet which shows the method (and some code) here[^]

I want to extract frames from video files without playing them. I used the GetCurrentImage of IBasicVideo2 to extract frames of videos as thumbnails of them. I Successfully extracted frames from video files of the format of WMV, AVI, DAT, ASF except MPG and VOB. When I extract frames of MPG and VOB files, It returns black frames.(The frames extracted are Successfully saved as bmp image files on my pc. however, they are all black frames.) Why??
Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;

using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

using System.Drawing;
using System.Drawing.Imaging;
using DShowNet;
using QuartzTypeLib;
namespace test2
{
/// <summary>
/// Window1.xaml 的交互逻辑

public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
string videoFileName = "d:\\aaaa\\《OVER IT》MV.MPG";
string bitmapFileName = "d:\\《OVER IT》MV.MPG.bmp";
GetThumbnail(videoFileName, bitmapFileName);
}
private bool GetThumbnail(string videoFileName, string bitmapFileName)
{
FilgraphManagerClass filgraph = new FilgraphManagerClass();
try
{
filgraph.RenderFile(videoFileName);
filgraph.CurrentPosition = filgraph.Duration / 2;
int width = filgraph.SourceWidth;
int height = filgraph.SourceHeight;
int pBufferSize = 0;
DShowNet.IBasicVideo2 video = (DShowNet.IBasicVideo2)filgraph;
video.GetCurrentImage(ref pBufferSize, IntPtr.Zero);
IntPtr pDIBImage = Marshal.AllocHGlobal(pBufferSize);
video.GetCurrentImage(ref pBufferSize, pDIBImage);
int stride = -4 * width;
System.Drawing.Imaging.PixelFormat format = System.Drawing.Imaging.PixelFormat.Format32bppRgb;
IntPtr scan0 = (IntPtr)(((int)pDIBImage) + (pBufferSize - (4 * width)));
Bitmap bmp = new Bitmap(width, height, stride, format, scan0);
bmp.Save(bitmapFileName);
Marshal.FreeHGlobal(pDIBImage);
}
catch
{
return false;
}
while (Marshal.ReleaseComObject(filgraph) > 0) ;
return true;
}
}
}

Hello All ,
I have developed my project . Now i want to Automate Test Framework . Ideally we should write Test cases as sooner as we writ the code .
But now i have develeoped all my Layers UI,BLL, DAL.
Now my question is In what order i should write the test cases I mean first i should for the dal then bll and then UI .
Or from top to bottom like UI--->BLL---->DAL
which approcah will be better Suggest .
Any pointers to above will be higly helpful to me
Regards,
Phani

This is nothing to do with C#; please post to the Test forum.

Usually you don't write unit tests for DAL. You should write tests for business layer. If it involves calls to DAL, it should be mocked. IMO, writing unit tests after completing the project is very tough. Your classes might not be test friendly and refactoring will be a pain.
