msiexec supports a /qn switch that will force it to run as a silent install.
But I am not aware of any equivalent to InstallShield's utility to generate a script to supply any required user fields.
You can supply default values in the MSI Properties table.
If you require things like a database login, obviously default values will not work. You may be able to accomplish this by having and administrator run an Admin install for his user groups. But I have personally never worked with Admin installs, and I am not very clear on exactly how they function.
Unfortunately the MSI documentation is poor at best ...

Hi all,
In my project we had system to log the exceptions through creating a text file for each day and writing the exceptions occured during tht day. The exceptions will be cathed through exception handling applied for necessary events.
There is system class called using 'System.Diagnostics' in .net.
Through which we can enter details in to a cutom log and we can see the details .
My point is it better to use the application orinted logging as we are doing or
Is it better to use the 'System.Diagnostics.EventLog()' for logging the errors.
Is any one worked on these concepts..? Please let me know the details.
Adavanced Thanks,
yeggu

Microsoft is pushing System Diagnostics logging, but I think you can argue for and against both methods.
There are two clear cut cases:
1) Windows Services should definitely use "System" logs.
2) If you still have to support Win98, there are no system logs, so a conventional file method is your only option. Of course you could create multiple versions, but I see no compelling reason to do so just for logging.
There are pluses and minus for both. For example, if you need to troubleshoot a weird problem it is a lot simpler to ask a client to find a folder and e-mail you a log file than it is to try to explain to them how to save a System log to a file and send it.
On the other hand if you actually have access to the Event log viewer, you can assign levels when you write messages and then System logs make it easy to find critical errors out of possibly a large number of insignificent messages.
Personally, I use both methods. If it is an application that I will be managing directly on a server I have access to I will use a System log. If it is a "3rd party app" that I don't expect to have direct access to once I've released it I ten d to still use the old fashioned flat file approach for the reason I've mentioned - I can always request an error log by e-mail if a problem arises.
You really have to evaluate your own specific situation.

Hii All!
I have created an application using Vb.net......Now I want to make its installer with Install Shield. I want the installer to check whether the .Net Framework is installed, if not then install it. I need to know that what kind of scripting is required to achieve it.
Regards

Search the MSDN for Bootstrapping the NET Framework. They have C++ source code that you can use as an example of how to check this. You should be able to convert that into Install Script, because is is essentially a "C" language.

Hi folks,
The following piece of C#.NET code creates an A4 size binary image by reading values from a two-dimensional byte array iPage[][].
Is there anyway I can further optimize the nested for loop inside the unsafe block? It is taking ~2.2s, and I'd love to bring it down further.
Sarab.
// page dimensions
iwd=iPage.Length;
iht=iPage[0].Length;
// create new bitmap
bMap=new Bitmap(iwd, iht, PixelFormat.Format24bppRgb);
// create bitmap data
bData=bMap.LockBits(new Rectangle (0,0,iwd,iht),ImageLockMode.WriteOnly,PixelFormat.Format24bppRgb);
// get bitmap position
Scan0 = bData.Scan0;
iStride=bData.Stride;
unsafe
{
// initialize pointer
byte *p = (byte*)(void*)Scan0;
int nOffset = iStride-iwd*3;
for(int y=0;y<iht;++y)
{
for(int x=0;x<iwd;++x)
{
if (iPage[x][y]==0) p[0]=p[1]=p[2]=255;
else p[0]=p[1]=p[2]=0;
p += 3;
}
p += nOffset;
}
}
PS. the code above is inspired from the article(s): http://www.codeproject.com/cs/media/csharpgraphicfilters11.asp

It looks like that about as fast as your going to get it without resorting to writing the thing in Managed C++.
Whoops! Accidently clicked Submit...
If you can come up with an algorithm to get rid of that if statement, you'll probably cut the time in half.

hmm... not so confident in managed c++.. can't remove the if statement either!
thanks anyways...

What values does the byte array contain? Do you only swap 0 <-> 255 or does the byte array contain different values?
When it contains only 0 or 255, you can use p[0]=p[1]=p[2]=~iPage[x][y];
How do you create the iPage array? If you could swap it to be iPage[y][x], you could evaluate iPage[y] outside the inner loop. (byte[] thisRow = iPage[y] and then continue to use the inner loop).
Also, you might want to eliminate bounds checking on iPage array access by using a foreach loop (it looks slower, but the C# compiler generates special code (no bounds checking) when foreach is used on an array).
So propably this could be faster: (provided you swap x and y in your array creation and use only the values 0 and 255):
foreach (byte[] row in iPage) {
foreach (byte val in row) [
p[0] = p[1] = p[2] = ~val;
p += 3;
}
p += nOffset;
}

Thanks Daniel!
Redefining my array as iPage[y][x] and using the foreach loop worked wonders! The execution time's safely within the acceptable range now 
Thanks !!!

Hi
I'm working on a solution containing 10-15 projects that generate DLLs.
Some projects use DLLs generated by other projects, I solve this by setting dependcies...
All DLLs are generated in one location.
No local copies are made when building the DLLs
For some reason, .NET hangs on to some of the DLL files (the .NET process) thus dening me from replacing them with new ones. From the 10-15 projects there are 2-3 DLLs being held as "open", even if no build\debug in process.
I solve this by exiting .NET, deleteing the DLLs and rebuilding them.
Any solution ?
Gilad.

Hello folks,
I wish to write text on an Image in .NET
I figure I can use the Graphics.drawString() method to do so, but it turns out that .NET would only allow me to write on images with non-indexed pixel formats.
The format I'm now using is 1bppIndexed, which allows me to keep the size of these image objects limited. I do not wish to change these images to a non-indexed pixel format like 24bppRGB (even though that allows me to draw text on the image), 'cause here I'm only dealing with binary images, each around 3500pixels by 2480pixels.
Since a format like 24bppRGB occupies much more space than what is required, I was hoping there would be a way to write on the 1bppIndexed images directly.
Any ideas?
Thanks...

If you're using 1bpp images, that's plain black and white. Truetype fonts require more color depth to perform antialiasing, so that won't work. You can go three ways IMO:
- render the font to a transparent image, convert to black & white and overlay over the original image, possibly creating a jagged font
or
- convert the image to more bpp, then render the text on top of it, then convert back to b&w. Will use a lot of memory for the converted image.
or
- use a bitmapped font that you can directly add to the image by using SetPixel()
Good luck..
|
|
|
|
|
Oops I overlooked the 1bpp INDEXED, so not black & white, but the same solutions apply IMO.
|
|
|
|

Understood the anti-aliasing part..
But didn't quite understand your first suggestion..
As for your second suggestion, I figure it doesn't solve the memory problem..
Guess will take a shot at attempting your third suggestion though...
Thanks...

Hi,
Strange behaviour with a System.Net.Sockets.Socket, reproducable on 95, 2000
and XP
If I reuse a socket object after initializing it I can reconnect without
problems.
But
If the application has been running for 23 minutes or longer, the socket
will forever
wait for BeginConnect() to finish. 
If I use a Connect() (also after 23 minutes) instead of async connecting the call will block
forever. 
I am using the following (pseudo) code to test. If running this after 23
minutes, the connect fails
and it is impossible to reconnect without restarting the application.
Is this known behaviour? Is there a workaround? Am I making a mistake? Help would be greatly
appreciated. For the time being I dropped a winsock control on a form and use that as my async socket.
regards
Guido
this is the offending code:
<br />
class SocketConnector<br />
{<br />
AsyncCallback m_callback = null;<br />
System.Net.Sockets.Socket m_socket = null;<br />
bool m_connected = false;<br />
public bool Connected<br />
{<br />
get { return m_connected; }<br />
}<br />
public void Connect(string ipaddress, int port)<br />
{<br />
m_callback = new AsyncCallback( OnConnect );<br />
<br />
m_socket = new Socket (AddressFamily.InterNetwork,SocketType.Stream <br />
,ProtocolType.Tcp );<br />
m_socket.Blocking = false;<br />
<br />
IPAddress ip = IPAddress.Parse (ipaddress);<br />
int iPortNo = System.Convert.ToInt16 ( port);<br />
<br />
IPEndPoint ipEnd = new IPEndPoint (ip,iPortNo);<br />
<br />
IAsyncResult ar = m_socket.BeginConnect( ipEnd, m_callback, m_socket );<br />
<br />
ar.AsyncWaitHandle.WaitOne(2000,false);<br />
<br />
if (!ar.IsCompleted || m_callback!=null)<br />
{<br />
m_connected = false;<br />
return;<br />
}<br />
m_connected = true;<br />
}<br />
void OnConnect(IAsyncResult result)<br />
{<br />
m_callback = null;<br />
}<br />
} <br />
<br />

Hi All!
I use XmlSerializer to serialize object and got the following:
<?xml version=\"1.0\" encoding=\"utf-16\"?>
<MyClass xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns=\"http://www.MyFirma.biz/MyNamespace\">
<Positions>
<Position>
</Position>
...
</Positions>
</MyClass>
Is it possible to get rid of the overhead (namespace info, schema info, xml version)? Anyway I do not need this info since parsing will be done without XmlSerializer.
So I need that output looks like below:
<MyClass>
<Positions>
<Position>
</Position>
...
</Positions>
</MyClass>
Thanks!

What is difference between IL and MSIL in Dot.net FrameWork.
Regards
Rajesh
rajesh

As much as I know both are the same in dot net
where as IL is a more generic term Java Byte Code is an IL
any code that runs in some kind of a virtual environment is an IL

In the .NET Framework, IL is MSIL. It's Microsoft Intermediate Language.
