Re: How to get the last command line argument or argument without the delimiter zxc8919-Sep-06 23:47 zxc89 19-Sep-06 23:47  I am not able to do with that..Is there any other possible way??? Re: How to get the last command line argument or argument without the delimiter Christian Graus19-Sep-06 23:49 Christian Graus 19-Sep-06 23:49  Why can't you ? There's no other way I can see, unless you're sure there will never be quotes, then the space is a delimiter. If you're unwilling to use a regex ( and if you don't know how, you should learn ), then you can always string mash your way to a solution, it's just nicer to do it properly.

So it will definetly have quotes..say eg: "d:\c plus\some.h"..so this string should always be specified in quotes.. Re: How to get the last command line argument or argument without the delimiter Christian Graus20-Sep-06 0:05 Christian Graus 20-Sep-06 0:05  OK, then your choices are regex or string mashing ( that is, counting spaces and quotes manually in code ) Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog StreamReader and special tag problem cecildt19-Sep-06 23:08 cecildt 19-Sep-06 23:08  Hi, I try to import a simple text file that have many rows with a special row format Example: |item|123|any items|4.50| When I read the lines in from the text file it removes the '|' tag. Why is that?? Example Code: StreamReader importFile = File.OpenText(txtPath.Text); txtLines.Text = txtLines.Text + importFile.ReadLine(); I know I'm missing something simple. Thanks for any help. Re: StreamReader and special tag problem Christian Graus19-Sep-06 23:15 Christian Graus 19-Sep-06 23:15  Perhaps | is a delimiter for the stream reader ? Is it reading the whole line every time, or up to the | ? Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog Re: StreamReader and special tag problem cecildt19-Sep-06 23:21 cecildt 19-Sep-06 23:21  I'm reading a whole line into a temp string and use the '|' tag to divide the string into column values. When I read the whole string from the file the '|' tag is missing. So, I cannot divide the string up. thanx Bit Fields Sabry190519-Sep-06 23:01 Sabry1905 19-Sep-06 23:01  Hi all I am trying to convert code that being written in C++ to C# and I found that structure that using a property in C++ called "Bit Fields" and I didn't found it in C#, is there any way to convert it to C# thx all typedef struct _tagCPB { unsigned short DialMode :1; unsigned short LineToPBX :1; unsigned short TriggerMode :1; unsigned short DetectRoaringRemoteHangUp :1; unsigned short DetectBusyRemoteHangUp :1; unsigned short DetectRemoteHangUpWhenRecording :1; unsigned short DetectRemoteHangUpAlways :1; unsigned short StopOperationRemoteHangUp :1; unsigned short MonitorDTMF :1; unsigned short MonitorEnergy :1; unsigned short DetectVoltReverseRemoteHangUp :1; unsigned short DetectSilentWhenRecording :1; unsigned short LearnPulse :1; unsigned short MonitorPulse :1; unsigned short MonitorTone :1; unsigned short :1; unsigned short OffHookDelay; unsigned short OnHookDelay; unsigned short FlashTime; unsigned short PulseMake; unsigned short PulseBreak; unsigned short PulsePostDigitPause; unsigned short ToneDuration; unsigned short InterTonePause; unsigned char OutsideLineAccess; unsigned char RingsToAnswer; unsigned short WaitAnswerDuration; unsigned short InterDigitPause; unsigned short NoSignalTimeOut; unsigned short MaxSilence; unsigned short MaxRoarDuration; char PlayGain; char RecordGain; unsigned char PlayMode; unsigned char RecordMode; unsigned char OffThreshold; } typeCPB; Re: Bit Fields Christian Graus19-Sep-06 23:19 Christian Graus 19-Sep-06 23:19  "C# does not support bit fields.

Glen Harvy Re: SELECT * FROM DB WHERE aFIELD = Null Christian Graus19-Sep-06 23:38 Christian Graus 19-Sep-06 23:38  OK, you're using table adapters. I don't think there's such a thing as an empty DateTime, it has to have a value, and so you'd need to have your database table accept nulls for this column, in order to store a meaningful 'empty' date time value. There is no such thing as DateTime.Empty.

The application would load the image in memory and extract(return) the text out of it. We are aware that it is png specific ocr process. But I am unable to find a solution for it. The other requirement is that the solution for the above mentioned problem should not use any executables. Instead if it uses any COM dll, then the problem is rectified. Thanks in advance, Rgds Amit Re: Extract Text from PNG file Christian Graus19-Sep-06 22:20 Christian Graus 19-Sep-06 22:20  Is the text stored in metadata associated with the image, or in the actual image itself ? That is, can you see the text when you view the image ? If so, this is a pretty big task Jatin Kakkar wrote: The other requirement is that the solution for the above mentioned problem should not use any executables. Instead if it uses any COM dll, then the problem is rectified. So you're basically looking for an OCR library ? I believe Atalasoft has one for sale. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog Re: Extract Text from PNG file Jatin Kakkar19-Sep-06 22:47 Jatin Kakkar 19-Sep-06 22:47  Thanks Christian for a prompt reply. I am looking for some free source code(downloadable) for achieving the same. Buying a tool will take a lot more time to be approved. Any help in this direction will be highly appreciated. Re: Extract Text from PNG file Christian Graus19-Sep-06 23:13 Christian Graus 19-Sep-06 23:13  OCR is never perfect. According to the google page someone linked you to: It also doesn't do well on grayscale and color documents, and it's not nearly as accurate as some of the best commercial OCR packages out there. Yet, as far as we know, despite its shortcomings, Tesseract is far more accurate than any other Open Source OCR package out there I take that to mean - good luck. If you need to use something free, then this is your best bet, perhaps you can turn the images to 1 bit first ? Anyhow, realistically, if you want any sort of guarentee, or any sort of support, you need to buy a library. You certainly don't want to be writing one. Also, be aware that OCR performs very poorly when the text is not lined up exactly, or has background noise. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog Re: Extract Text from PNG file Jatin Kakkar19-Sep-06 23:58 Jatin Kakkar 19-Sep-06 23:58  Thanks again... As correctly mentioned by you that OCR-ing is not a perfect way of achieving the above mentioned task. Is there any other way out to extract the text from the PNG files. Buying a library seems to be the last resort for ur as the approval wfor the same would take a long time. Re: Extract Text from PNG file Christian Graus20-Sep-06 0:06 Christian Graus 20-Sep-06 0:06  No, OCR is the only way. The text does not exist anymore, except as pixels that have no knowledge of their meaning to the human eye, so you need OCR to recognise them and pull them out. Why would it take a long time ? Is this a commercial project ? If so, are your managers living in a fantasy ? OCR is a complex task, if they are being paid for this work, then a commercial library is the only choice that makes sense, unless you happen to get lucky with a free one. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog Re: Extract Text from PNG file Jatin Kakkar19-Sep-06 22:58 Jatin Kakkar 19-Sep-06 22:58  Thanks once again. The text which needs to be captured from the image file is actaully the part of the image (the text is visible in the image). I need to capture that text. Re: Extract Text from PNG file S. Senthil Kumar19-Sep-06 22:46 S. Senthil Kumar 19-Sep-06 22:46  Google has a free OCR library, Tesseract[^]. Does that suit your requirements?

Gridview Binding Brendan Vogt19-Sep-06 21:43 Brendan Vogt 19-Sep-06 21:43  Hi, I have a page that has a list of wineries. If a winery is selected, then it displays a list of wine for that winery. No I can go an choose which one of the wine I want to add to the order. Beneath the winery dropdown and wine selection, I have a gridview that displays all the order items. Here is my confusion, when I add the wine as an order item to the OrderItems table, it works fine, but the gridview still displays the orderitems up to the last inesert. It's as if it does not refresh the gridview. I have to press F5 to have the news items added to display in the grid view. Is there a way of refreshing the grisview when the items are added, because it does make a round trip to the server to insert the order items. Please can some help. If there is confusion, please ask and I will try to explain better. Regards, ma se
