The OCR library you're using is making the mistakes. It's probably got nothing to do with the image itself, but the font used in the image and the quality of the OCR software.
As for TIFF support in GDI+, I'd recommend using a third party library to do the image manipulation. TIFF support is a bit spotty in GDI+ and it doesn't have a suite of functions for cleaning up images.

Hi,
The limited experience I have with OCR told me you need 16 pt or larger to get reasonable results.
At 10pt each characters is only a few pixels wide and high, insufficient for OCR to work properly.

How are you converting it to a bitonal representation? This is an information loss and thus probably an error source.

Trying to read freshly-generated textual information off a screen tends to be a different problem than reading a scanned document; programs that are designed for one problem may not be optimal for the other. Programs that are seeking to read information off the screen generally have to cope with a lower-resolution version of characters than programs which are dealing with a scanned page, but in many cases have the huge advantage that the letter forms on screen will often be much more consistent than those in a scan. This allowed for much more efficient operation than would otherwise be possible. Even the original IBM PC could read text off the low-resolution graphics screen; indeed, that's how the BASIC interpreter worked in graphics mode. The "Insert" key was a bit sluggish in graphics mode, but that's because each character had to be read off the screen and rewritten one space over. Of course, most applications don't use monospaced text aligned on byte boundaries, but modern PC's don't have to run at 4.77MHz (4*chroma/3).

hlo everyone..
how can a tune sung by a user (humming) be compared with the songs in the database & produce similar results??
since the pitch of man & woman varies widely, how can the results can be made accurate?

I would have used Artficial Neural Nettworks for a task like that. If you don't wanna code it from scratch you can use a library like AForge.

I give up - How do I get the caller host from a WCF context when the service is hosted as a ServiceHost running as an NT Service.
The best I can come up with is:
string host;
if (Demon.IsDemon) {
//Thought this might do the trick - but doesn't
OperationContext oc = OperationContext.Current;
host = oc.RequestContext.RequestMessage.Headers.From.Uri.Host;
} else {
//This works in IIS
host = HttpContext.Current.Request.UserHostName;
}
I have searched for hours and just can't find the solution - Is it really crazy to want to know the host that is calling my service?

Okay, finally found the answer here... thanks Phil

It seems this was an after thought in WCF, but it is imho essential to have the ability to know who is calling my public methods, and how - even if it is just for simple logging or debugging.
I know the request may have been proxied accross the world, and that the physical 'sender' may not be reachable, and that the underlaying protocol may not be 'whatever', but I will 'always' want to access this kind of information.
It is simple really, someone calls me and I give them an answer - but only if I can see their number in the display. Maybe I just want to call them back later.
So to simply sum up what I wanted this for:
public void Subscribe(string MyCallbackProtocol, int MyCallbackPort, string MyCallbackInterfaceName){
string YourAddress = (I want to determine this! I want to call you back later.);
}
There are 10 kinds of people that understand binary, those that do and those that don't...

Hi,
I have a WebService-WS, WebApp-WA and DTOproject-DTO. I made a DTO, SZ, serializable and added it as reference to WS and WA. When I call webmethod WS.oneWS.method() it returns an array of WS.SZ where I need DTO.SZ. Am I missing something here apart from making SZ serializable? Please help me.
Thanks in advance.

It's not really the proper way to stop a thread, but you just call it's Abort method.
someThreadIStarted.Abort
|
|
|
|
|
Thanks for Replying I tried this
like
Thread.abort
thread.resetabort
thread.suspend
But nothing works
It give error that Call is from some outside referenced Thread
|
|
|
|

What's the exact error message?? Are you trying to kill a thread your code didn't create?? Or are you trying to have a thread kill itself??

I have a setup.ini file has the information below, created in .NET setup project
[MSILoader]
MSIFileName=Allianz-PHI-Setup-SW2.msi
[FXSection]
SupportedRuntimes=1.1.4322
InstallUrl=http://go.microsoft.com/fwlink/?LinkId=9832
Message=1.1.4322
UseDefaultMessage=1
The out put of the above setup projects are setup.exe, setup.ini & Allianz-PHI-Setup-SW2.msi
I need to install one more msi package during the setup.exe installation(that is internally calling Allianz-PHI-Setup-SW2.msi) like the same I need to add one more msi called sqlxml.msi.
I need to add the sqlxml.msi details into the setup.ini file so that both the packages will get installed.
Please advise

Hi,
I have a VS2005 Setup & Deployment project and I want to use a Windows installer condition to check to see if a folder already exists (sub-folder in the Application Folder hierarchy). I used the condition 'NOT Installed' in the properties for my sub-folder in the File System tab, but it looks like it's installing the sub-folder every time. Is 'NOT Installed' the right property to check to see if a folder already exists, or is that only used to check if the application is installed or not?
Thanks

Where I work we have a support tool that does many custom fixes.
Our desktops in the business are all locked down and have restricted/minimal access to the Control Panel.
We currently log on as Admins to machines to get full functionality or do a RunAs on the require .cpl applet.
Is there a way we can remotley contol another machines control panel or individual control panel applets; so the other machines control panel appears on our machines, so we dont have to remote to other machines or log users off
Thanks in advance

What does this have to do with the .NET Framework.
And, no, you can't do this. Remote code execution is a HUGE security risk, and is therefore HIGHLY restricted. I don't know of any control panels that support remote management.
