hi,
At this time i'm ready to do the OCR project based on CLR in vc++. But, my code snippet giving an error when the c++/clr compile the particular line....

void Form1::SOCR_Click(System::Object^ sender, System::EventArgs^ e)<br />
{<br />
int i,j,k;<br />
String^ fName = "Citi.tif";<br />
MODI::Document^ doc = gcnew MODI::DocumentClass();<br />
doc->Create(fName);<br />
doc->OCR(MODI::MiLANGUAGES::miLANG_SYSDEFAULT,true,true);<br />
<br />
for(i=0; i < doc->Images->Count; i++)<br />
{<br />
MODI::Image^ img =(MODI::Image) doc->Images[i];// Error will be thrown on this line<br />
}<br />
<br />
}

where,
Image - Interface class

The Error is...
Error 1 error C3149: 'MODI::Image' : cannot use this type here without a top-level '^'

please help me...
thanks in advance...

I think it is your problem, isn´t it?
If not sorry!

You're casting to a MODI::Image instead of a MODI::Image ^.

Does .Net have anything like COM standalone server?

Hi I am a newbie in learning .Net now.

I had in mind of writing something similar to a COM standalone executable and my GUI frontend executable will communicate with this server. Does .Net have anything like this?

Please enlighten me!

Thanks for your time!

Yes - you can achieve this effect using Reflection or Remoting.

Hi, thanks for the reply!

I got another question, the so-called server I am going to write is on the same computer as the GUI executable, it is not on a remote server or another networked computer. Does that work as well?

Thanks again!

VS2005 does work with .NET 1.1, but only because 1.1 is (basicaly) subset of 2.0 If you want to see only 1.1 classes in intellisense etc, then no, this is not possible. "Orcas" will enable to switch between .NET Framework 2.0, 3.0, 3.5 but till then, every VS unfortunately targets different version of framework.

As dnh said, Visual Studio 2005 wont show you the 1.1 intellisense or other addvanced features like that.

But you can build 1.1 solutions with VS2k5 using MsBee:

I don't think that would be possible. I would suggest the following related links on this topic:

1) http://msdn2.microsoft.com/en-us/netframework/aa570326.aspx[^]

2) VS 2002 and 2003 convertor: http://www.codeproject.com/macro/vsconvert.asp[^]

3) But 2005 to previous versions, I haven't come across any convertor hitherto.

Weird System.BadImageFormatException

Vaibhav Gawali12-Jun-07 19:26

My application runs normally all the time without getting any BadImageFormatException. But if no user interaction happens for more than half an hour and user clicks on one particular menu then application crashes with System.BadImageFormatException. This is happening for one particular toolstrip menu item only but not in normal circumstances.
Please let me know the solution as soon as possible.

i got a problem with bitonal image. when i do resizing it's losing it's quality and image losing it's viewability. i am facing this issue with .net gdi+. i also tried converting bitonal image to 32bits bitmap and then resizing it using smoothing with both bilinear and bicubic interpolation. but no use. is there any other way?

Maintaining aspect ratio can be bit tricky while attempting resize. Did you check out this article for some tricks?

I would also suggest you can have Irfanview which would quickly resize in the desktop. I have a brief review on Irfanview over here: http://lavanyadeepak.blogspot.com/2007/04/short-review-on-irfanview.html[^]

Show dividing lines between subroutines in text editor

B_miller12-Jun-07 5:09

B_miller

12-Jun-07 5:09

This is probably a really basic question but I can't figure it out for the life of me. I am running VS.Net ver 7.0.9466 with .Net Framework 1.0.375. On every other version I have seen, there are lines in the text editor that divide sub routines to make it easier to distinguish where on sub ends and the other begins. This version does not show these lines. Is there a setting or option that needs to be enabled or is this feature just not available on this version?

Re: Show dividing lines between subroutines in text editor

My recollection says that it did show these lines, but this article disagrees[^]. I don't recall if there was an option to turn them on. In Visual Studio .NET 2003 the option is in Tools, Options under Text Editor, Basic, VB Specific and is named Show Procedure Line Separators.

C# and C++ do not have this feature in any version of Visual Studio.

I don't know of many people still using VS.NET 2002 and .NET Framework 1.0. Virtually everyone upgraded to VS.NET 2003 and .NET 1.1 (it helped that for several months, the upgrade only cost £19!)

Personally I ensure there are multiple blank lines between procedures in any case. For me, that's enough of a separator.

BeginInvoke in multi-processor machine

Adam_contel12-Jun-07 5:06

Hi I wrote a multi thread program (windows service) that writes to a log (text) file.
So I used beginInvoke so that only one thread will write to the file.
When I tested it on my machine it worked fine but when I installed the program on a multi processor production server it crashed. Frown | :(

Code:
Public Delegate Sub DelegateLogError(ByVal txtMsg As String)

Public Class Server_main

   Private log_ As LogHandler

   Public Sub logError(ByVal txtMsg As String)

     Dim del As New DelegateLogError(AddressOf log_.LogError)
     Dim ac As AsyncCallback = New AsyncCallback(AddressOf cbLogError)
     del.BeginInvoke(txtMsg, ac, Nothing)

   End Sub

   Public Shared Sub cbLogError(ByVal ar As IAsyncResult)
     If ar.IsCompleted Then
       Dim del As DelegateLogError = CType(CType(ar, _
       System.Runtime.Remoting.Messaging.AsyncResult).AsyncDelegate, _
       DelegateLogError)
     del.EndInvoke(ar)
     End If
   End Sub

   Protected Sub Initialize()
     Try
       logError("Starting Server")
       .
       .
       .

End Class

Does anyone have any idea how to make it work on a multi processor?

Thank you

Adam

Hi,

This looks like Basic.NET doesnt it ?

If it runs fine on a single-processor and fails on a multi-processor, then I would
suspect you have some thread synchronization problem; but I would expect it to be
elsewhere, not in code that you force to run on the UI thread.

Why is it you think the logging is causing the problem ??

To investigate, you might replace your logging stuff by simple Console.WriteLine()
operations (or whatever is equivalent in Basic.NET); remark that Console by itself
is multithread-safe.

Hi,

your usage of BeginInvoke doesn't say that your log method is only called by on thread at a time. You have to lock it instead:

'class variable
Private objMyLock As Object = New Object()

Public Sub LogSafe()
   SyncLock objMyLock
      'Do your logging here
      'Once one thread has passed SyncLock all next threads
      'will stop there until this thread has exited the block.
   End SyncLock
End Sub

Hi yes you are right it didn't work on one thread
so I used monitor.enter and monitor.exit instead.
Thank you
