hi all,
i have a class stored several data objects such as string, integer, double... for data exchange in 2 threads.
i wonder any method to lock these data members of a class.
i mean, for a member function i can use mutex , lock for exclusive access. but, for a data object, how can i lock it?
i have 10 data members in the class but i don't want to create 10 member functions for accessing them.
or, is it essential to do this?
regards,
jim

You can use the Monitor.Enter/Exit and there is a Lock method but I cant remember what class it belongs to
I'm not an expert yet, but I play one at work. Yeah and here too.

you can download the .NET Framework SDK Version 1.1 here[^]. It contains lot of samples to get you started on c#.
You can get the vs.net IDE or just use the command line compilers.
For image processing you can use inbuilt classes or use Direct X 9 wrappers.
You can get them here[^]. I would also suggest you to have a look at CG's articles here at CP.
Image Processing with C# and GDI+[^]
Hope this helps.

Have you checked the installation directory (C:\Programs\...)?
Maybe the setup has not copied the .exe file.

its there

Did you check the event log for any error messages also do you have privileges for running the service.

Theres no error messages. I'm the admin of my pc. And if I run the installer again it wants to remove the service.
I have written any code in the installer. Do I need to write any code?

Before you create a setup project you have to add a installer to you service.Did you do that?

Select your Serviceclass,then write click on the form add click Add Installer(in design mode),see there are some properties there and set them as you want.Then you can create setup and add output there.

Hello,
I am fairly new to .NET and wanted to ask recommendations on the proper use of sqlDataAdapters regarding using one sqlDataAdapter on each form created or, what is the best way to centrally setup the sqlDataAdapters that each form can access the same sqlDataAdapter. In Delphi, there is a DataModule (threaded) that allows you to put your non-visual data access components on it and then access the DataModule from each form or function that needs data access.
What might be some articles or references to a question like this?
Thank you,
|
|
|
|
|
I'm not sure what exactly you want to do,but if you need the same sqlDataAdapter in each form you can pass it in constructor of your form or as ana property.

you could drag the data adapter from the server window on your left
I see no need for that since a data adapter isnt that expensive

You need to do something like this, i havent tested this, but it should work.
byte [] data = null;
WebRequest req = WebRequest.Create("http://someurl/page.asp");
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
Stream output = req.GetRequestStream();
data = System.Text.Encoding.ASCII.GetBytes ("some string to be posted");
req.ContentLength = data.Length;
output.Write (data, 0, data.Length);
output.Close();

Is there any way to click somewhere in the datagrid, but have it highlight the entire row like it would if you clicked the row on the far left outside all the cells?
I can get it to highlight the entire row, but it also highlights the text inside the cell i clicked on.
I guess I'm answering my own question in a way. Now I need to find out how to make the cell text not highlight. =)

Override OnMouseDown etc.
protected override void OnMouseDown(MouseEventArgs e)
{
base.OnMouseDown(e);
//selecting row
this.Select(this.CurrentRowIndex);
//hilighting the cell
DataGrid.HitTestInfo hi=this.HitTest(e.X,e.Y);
if(e.Button==MouseButtons.Left && hi.Type==DataGrid.HitTestType.Cell && hi.Row>=0)
{
...
}
}

Windows standard is to use Ctrl key to select multiple individual items and use Shift key to select a range of items.
Now I have winform datagrid, shift/Ctrl are working fine in the row header, but I want them to work within datagrid too. Say you can select multiple fields in the same row or same column. Can I achieve it?
Thanks for sharing your knowledge.
