Don't take my word for it! Start asking around about what is considered best practice for database connections.
It is true that ADO.NET does do connection pooling, but it does the very same thing that I've talked about. The connection to the server is closed, releasing the connection license on the server until ADO.NET decides it needs to be opened again.

hi to all,
can anyone point me in the direction of how to create a frontend (web-based) to record messages from a client and store them on a server(they log into) as mp3 or files ready for on-demand streaming through WMS?
tutes or links on audio recording / resampling ??
is this even possible using c#? eventually would also have functionality to dial into server (cell, landline) and record files that way ??
kind regards

I have created a Windows service which compares the Current Date with one stored in the registry and if they are the same or the date stored in the registry is older than the current it launches an updater.
The updater is an exe i created too and it works perfectly using the ThreadPool class, but the main problem is the files it download could be images as they could be videos so the download may take a time. I have some buttons and properties in the updater but if its launched from the Windows Service , the updater runs in the background.
I know theres a property from the management service aplication( Allow interaction with desktop) but ¿ is there a property which allow u to do that from the main code, wen u install the service or so?
Dont like the idea of phoning my customers and tell em what to do or just drive for hours just to go there and make 2 clicks.
Ty for ur time.

I need tobe able towrite to the registry in my app every time you run it, but on none-administrator accounts you do not have the permission write to parts of the registry,is there a way that i could get such permissions without logging on to an administrator account, or changing the accounts so that they can write to the registry?
thanksfor any help!

|
|
|

No, there isn't. And you can't just ask for and get the permissions needed either.
The accounts must either be given the permissions to write to those sections of the registry you need, (BTW, not a good idea!), by modifying the ACL's on the specified keys, or you change the users group rights to a higher level to allow greater unrestricted access (also a lousy idea).
Why must your users write to restricted portions of the registry?

hi,
i am feeling a poblem. can anyone help me in blocking a packet on the network. so we check the paket and then route it if it is valid or drop it.
so the problem is to sniff snd blok packet.
Thanks.

You don't know much about network traffic, do you?
Sniffers only look at what's passing by, they don't intercept and block anything...
What your looking for is a router! Unless your machine is physically in the path of the network packets, meaning that ALL network traffic on that segment passes THROUGH your machine (not aorund or passes by it), there's nothing you can do to block anything.
BTW, this is already implemented in the form of Windows Routing and Remote Access...

Is there something faster than .|[\r\n] in Regular Expressions ?

I want to match multiple-line comments from /* to */ so I use:
Regex regex = new Regex("/\\*(.|[\r\n])*?\\*/");

Hi there,
The following code generates the CS0122 "System.IO.FileStream.FileStream() is inancessible due to its protection level."
What am I doing wrong?
Thanks,
Akos
>>>>>>>>>>
The code:
using System;
using System.IO;
namespace MyStreamReader
{
///
/// Summary description for MyStreamReader.
///
public class MyStreamReader : System.IO.FileStream
{
public MyStreamReader()
{
//
// TODO: Add constructor logic here
//
}
}
}

the mistake in your code is that you are trying to use the default contructor of the filestream class. But this constructor isn't accessible. A solution to this problem is just using another constructor of the filestream class. You can call other constructors via the base synonym(as you can see in the following code).
class b : System.IO.FileStream
{
public b(string str): base(str,FileMode.OpenOrCreate)
{
}
}

Beauty! Thanks Hooray!

when i use the method Mesh.clean(...), throw a exception of System.NullReferenceException. this is my code:
private void LoadMesh(string file)
{
ExtendedMaterial[] mtrl;
GraphicsStream adj=null;
// Load our mesh
mesh = Mesh.FromFile(file, MeshFlags.Managed, device, out adj, out mtrl);
// If we have any materials, store them
if ((mtrl != null) && (mtrl.Length > 0))
{
meshMaterials = new Material[mtrl.Length];
meshTextures = new Texture[mtrl.Length];
// Store each material and texture
for (int i = 0; i < mtrl.Length; i++)
{
meshMaterials[i] = mtrl[i].Material3D;
if ((mtrl[i].TextureFilename != null) && (mtrl[i].TextureFilename != string.Empty))
{
// We have a texture, try to load it
meshTextures[i] = TextureLoader.FromFile(device, @"..\..\" + mtrl[i].TextureFilename);
}
}
}
// Clean our main mesh
Mesh tempMesh = Mesh.Clean(CleanType.Simplification ,mesh, adj, adj );
// Replace our existing mesh with this one
mesh.Dispose();
mesh = tempMesh; //when run here, throw a exception
}
i have no idea that what can i do.

I've been trying to write a quiz program using windows forms. I've been searching around for examples and can't find anything. Everything I read or find is only text related. How can you include an image in a dataset or datatable??
Could someone please write a basic program with 2 multiple choice questions containing some text and an image. Perhaps you could email me the source code or something. Maybe use a xml file or txt file to contain the quiz data.
An example question could be:
What type of fruit is in the picture?
Choice A = Apple
Choice B = Orange
Choice C = Pear
Choice D = Carrot
Any help with this would be really appreciated!

Do you want to put images into your database, or could you use an array as your data source ?

Using an array for the data source which could be used to then load the image from a bmp or jpeg file.
Thanks..

Then why can't you do what I suggested to you days ago ?

Couldn't figure out how or where to add the code as I didn't understand how to use the code with the question code.
|
|
|
|
|
Why didn't you ask ? Will you abandon the next worthwhile solution if you can't get it right away ?
The idea is to keep a list of images, and points where they appear on the screen, in a structure with the text. To 'draw' each question, dump the text and then iterate through the images, drawing them in the right place. This will need tweaking if they area they are drawn on can change in size, to scale image location.
