There's some good books at Amazon that go over OCR from start to finish. IT's still a major task, I assume most articles basically assume you have enough background knowledge to do it.
I can't find my book to give you the title, but if you search Amazon for image processing, you'll find it. Of course, the code is all going to be C, certainly not C#.

Hi All,
I think I've tracked down my earlier Debugging issue. I think the way I have my external DLL's and References to them messed up. What is the correct way to handle this?
I've tried creating a Solution Folder called External_Libs and then added things in there, then my solution projects complain about not being able to load them. So I removed that folder and added in an External_Libs directory to each project and then added in the required DLL's into those and referenced them in those dirs and I still get the same error.
I wanted to keep all the external DLL's in a single directory (External_Libs) rather than having them all set to "Copy Local = True" then ending up with a mass of DLL's in the root directory.
Bit confused!!

why do you want to creat a solutio folder, why don't you make a class library for the APIs you need? gather APIs in a project and build a single dll from that project. then you can add it by 'add reference' in any of your .NET projects.
if there is another error, check your used APIs whether they are correct or not at pinvoke.net.

The libraries I'm using are 3rd party like Infragistics and so on ... they are not designed to be built into another dll ...

I have a custom control that inherits from ScrollableControl. I'm doing some drawing on the control and one thing I'm missing is a ScrollIntoView(Rectangle), where the rectangle corresponds to the same as Control.Location combined with Control.Size would.
I have tried grabbing PaintEventArgs.ClipRectangle or Graphics.VisibleBounds combined with Control.HorizontalScroll.Value/Control.VerticalScroll.Value and Control.Size, but these seem to include the area "behind" the visual parts of the scrollbars (ie. some graphics will be hidden behind the scrollbars).
How do I go about this?
Thanks!

Hi All,
I'm just doing my first installation check. The machine i'm installing my app on doesn't have VS or anything with which to debug things with, are there any solutions to this to find out exactly what is causing the problem? Is there some .NET tool to aid in this process?
Thanks,
Jammer

Logging is the way. If your application logs, checking the log reports can findout what went wrong.
|
|
|
|
|
Yeah, I think I'm going to have to extend the logging ...

Well, you may be able to attach a remote debugger and debug with that. This depends on security settings, but is probably the best way for you to do it.

Ok, i'll have a read up on remote debugging. Thanks Pete.

hi friends,
as you know, when you initialize a String, you can achive the characters by:
String str = "hello";
char character = str[0];
but i want to achive to the character without using any methods or facilities prepared in String class. how can i write a method to achive?
thanks

it returns a char. Your example will show the ascii value of the character at the supplied index and not the character.

Looks like someone asked you this for an interview ? You can iterate though the string like this
foreach (char c in str)
{
Console.WriteLine(c);
}

oh excuse me you are right, it returns a char.
but i don't want to use 'foreach', too.
i want it for something like an interview  .
thanks again

I don't think that there is a way without using anything related to string class. I am not sure though.
|
|
|
|

How about this
string str = "hello";
char[] c = System.Text.ASCIIEncoding.Unicode.GetChars(
System.Text.ASCIIEncoding.Unicode.GetBytes ((str)));
|
|
|
|
|

If this is the interview question where you have to reverse a string, or ToUpper it or something like that without "using any built in methods" then you can assume you are able to use the char this[int] indexer. Good luck.

I am doing a program that inserts pictures to a panel. I have a progressbar that shows how long time it takes to upload. The problem is that i want to Join() this thread so it waits til its finished loading. I tried to use threads but it doesnt work because of threads between different controls... So i read and tried to understand how to work this out. Now ive done it with backgroundworker and it works but how should i do to Join()...
