You probably would find it easier to use DirectX. If you must use OpenGL, then I'd use C++, you're not going to be doing much directly in C#, I would expect.

If your using forms to display then the OGL takes over all drawing so you cant use the default drawing UI components.
You'll have to create your own GUI components in OGL - i've done this in DirectX, and there are some good tutorials out there (CUnit for Directx is a good overview)
Its been a long time since i used OGL, but to write to the panel instead of a form i think its just passing the Win32 draw parameter fo the panel instead of the form when you start OGL (it really was a long time ago)

It seems that the thread which is assigned for the particular client is still running on the server machine and trying to get communicated with the client,. This is making the processor utilization high. One solution could be sending one quit message to server when client is going to close. When server gets the message, release the threads and all other resources allocated for this client. I think this will solve problem.

-I have made an application in c#.net,window application.
-Now to install it on other computers, i want to make its setup.
-I have already made setup of the application using d below link :
http://www.codersource.net/csharp_installer_projects.html[^]
- I have made my database in sqlserver2000,
-I have copied its 2 (database file and log file) from its actual path (C:\Program Files\Microsoft SQL Server\MSSQL\Data) and pasted it in my dotnet application folder.
-While making setup of application i just included those 2 database files with the application(from >bin>debug) of project (as instructed in above link)
Setup is build without errors, but when i run i get errors,they r related to sqlserver.
-Do i need to make database setup separately?How?
I would be grateful,if any help is offered.
Thank you.
Regards nekshan.

You said you're using SQL Server, and copied the database files on the client machine, but is SQL Server actually installed on that machine? If not, you're out of luck.
You will either have to install SQL Server on the machine where you install the database files, or you will have to go for some other data source, like MS Access.
Cheers,
Vikram.

Yes, SQL Server is installed on that machine.
Even if i run that setup on my own pc(which has sqlserver), it is giving this error

I've read the article that tells u how to make a setup... and the database it was talking abt was a MS Access Database which they copied in the application folder but in case of MSSQL, I think this will not suffice coz you need to restore that Database in the SQL Server on the end user machine. or whatever ur network configurations are. So just install the application on the end user and restore the Database on the End user machine so that it can work properly.
hope it helps

Anybody faced similar problem here? is there any problem with
TcpListner,Client or streams?

Hi every one,
I just started to make an MDI aplication in C# and I was tryin to split the MDI parent window showing a treeView to manage a few links. and I was trying to open a new form when we click on a tree Node so I coded some thing like this in the after select Event
void treeView1_AfterSelect()...<br />
{<br />
myForm1 f = new myForm1();<br />
f.Show();<br />
}
but the prblem is that the new window doesnt show up. So what should I do here??
thanks in advance
Rocky

make a break point and
be sure that it enter this handler in debug mode
if it does not enter this handler then try to code another handler to the treeview control in order to display the form
also make form.MDIParent= this ; this mean the parent window

I coded somethin like this and its definately goin in that event handler
void tV1_NodeMouseClick()..
{
if(e.Node.Name == "Node0")
{
Form1 m = new Form1();
m.MdiParent = this;
m.Text = "Trial";
m.Show();
}
}
It works if I remove the splitcontainer from the MDI parent form but it doesnt show up at all when I have this splitContainer on. What I was tryint to do is to show the new window in the other half of the screen while keeping the treeView on the leftside of the screen
if there's an alternative in ur mind on how to appcomlish this idea
|
|
|
|
|
make the panel2 of the split container collapsed
panel2Collapsed=true from the properties window
and resize the panel1 as you want..
then try your code , it will work well..
Myform frm=new Myform();
frm.MDIParent=this;
frm.show();
and good luck to complete ur project
