Can anyone help me in reading this data.config changing some of its values and wrting it back in the same xml.
Sample data.config is below
<configuration>
<connectionStringCollection>
<XmlSerializerSection type="test values">
<ConnectionStringDataCollection xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Connections>
<connectionString>
<Name>default</Name>
<ConnectionString>Data Source=test123;User Id=aaa;Password=123;</ConnectionString>
</connectionString>
<connectionString>
<Name>default2</Name>
<ConnectionString>Data Source=test123;User Id=bbb;Password=123;</ConnectionString>
</connectionString>
</Connections>
</ConnectionStringDataCollection>
</XmlSerializerSection>
</connectionStringCollection>
</configuration>
Please help me in doing this with C# or VB.net code
Thanks in advance

Load the XML file into an XmlDocument instance, select the nodes you want to change using its SelectNodes or SelectSingleNode methods and finally change the node value as wanted. The documentation of the mentioned class and methods contains many examples, so you should be able to figure out the coding yourself.

Hi!
I want to make an image filter in Visual Studio C# .The function of such filter is that redraw the original image only with its dark pixel.
I used following logic but its too slow and not efficient
for (int i = 0; i < 300; i++)
{
for (int j = 0; j < 200; j++)
{
p = new Pen(bitmap.GetPixel(i, j), 1);
for (int r1 = 0; r1 < 100; r1++)
{
for (int r2 =0; r2 < 100; r2++)
{
for (int r3 = 0; r3 < 100; r3++)
{
if (p.Color ! = Color.FromArgb(255, r1, r2, r3))
{
p.Color = Color.Transparent;
}
g.DrawRectangle(p, 1 * i, 1 * j, 1, 1);
}
}
}
My second question is that how we can manipulates the images in visual studio c# .net ,like convert the image in black &white color,grayscale etc etc
Please send the some code or hints+links

Hi,
take a look on the class ServiceController (include Reference System.ServiceProcess).
Sample:
ServiceController controller = new ServiceController(<servicename>);
controller.Refresh(); // Controller should read state
if (controller.State == ServiceControllerStatus.Running) // Service is running...
...
you will receive an exception if the specified service does not exist.
|
|
|
|
|
|
Dim service() As System.ServiceProcess.ServiceController
Dim i As Integer
service = System.ServiceProcess.ServiceController.GetServices()
For i = 0 To service.Length - 1
If service(i).ServiceName = "wampapache" Then
If service(i).Status = ServiceControllerStatus.Running Then
' Kill the Service
service(i).Stop()
Application.Exit()
Else
Dim startInfo As System.Diagnostics.ProcessStartInfo
Dim pStart As New System.Diagnostics.Process
startInfo = New System.Diagnostics.ProcessStartInfo("E:\Biswabhusan_Collection\COREPRACTICE\TestService\wamp5_1.6.1.exe")
pStart.StartInfo = startInfo
pStart.Start()
pStart.WaitForExit() 'Your code will halt until the exe file has executed.
End If
End If
Next

List<int> lst_int=new List<int>();
lst_int.Add(3);
lst_int.Add(5);
lst_int.Add(2);
lst_int.Sort();
MessageBox.Show(lst_int[0].ToString());
struct mystruct
{
int x;
int y;
}
How do I implement "sort" for lists of type mystruct?
List<mystruct>
List<mystruct> lst_mystruct=new List<struct>();
mystruct mys;
mys.x=10;
mys.y=12;
lst_mystruct.Add(mys);
how do I sort now?

Implement the IComparable and/or IComparable<mystruct> interface(s) in your struct.

Hi all,
I want to develop a textbox(more like richtextbox control) where users can enter some text, but the bitmaps are displayed instead of characters. The user should be able to edit the text and the corresponding values should be preserved(between the text entered and the corresponding bitmaps). How do i go about doing this. Is there a way to override the paint event of the textbox so that the bitmap is drawn instead of charcters.
Please help.
Thanks for reading.

The textbox is not written for overriding, as it paints itself outside of any paint event, getting it to custom draw is always nasty. I'd say it's almost better to start from scratch.

Looking for info on how to populate listview from folderbrowserdialog once the user selects a file followed by the ok button.
I'm relatively new to programming with C# so the more detail the better.
Thank you

Hi,
First, after the user selects a folder, you know its path. You can GetDirectories from that Directory object. Then iterate through the collection, filling each folder name in the list box. I think that there will be a better way of doing this, but i dont know about it. This solution will surely work in your case. But this is not a good practice, I guess.

Use Directory.GetFolders and Directory.GetFiles, merge those arrays together and make them the datasource on your listview.
How new is 'new' ? Have you taken the time to learn C# before learning Winforms ? Have you worked through any books ?

Hi,
From your question, it seems that your are providing the Edit facility in the grid itself. If this is the case, you can place all the validators in the EditTemplate of the column. These will automatically fired when user clciks 'Update'.
I hope you got my point.

I wanted to say that, you can place validators in the EditItemTemplate of a GridView. For this you will have to convert that column in template comlumn.
