How to extract data from screen or picture


Hi Guys,

I'm thinking of a way to extract data (e.g. the data displayed in a flash game in IE, I want to extract user's level/HP, etc). Is it possible to make it only from analyzing the data displayed on the screen without writing network injecting code to get the data?

Cause I want to do it with a legal way, guess this can be related with some graphic technology.

If it's possible, can someone give more guidance about this? Great if can be found in .Net.

Thanks a lot.

The maximum string content length quota (8192) has been exceeded while reading XML data.

Hi, I have been working on implementing a WCF service and have run into this problem with the maxStringContentLength.  I have read a bunch of posts here on how to correct it and none of them have worked.  I have updated my web.config in my local IIS5 published service to be maxStringContentLength="2147483647" and have updated my application's app.config to be maxStringContentLength="2147483647".  I delete all DLL's, rebuild, restart IIS, make sure all VS 2008 virtual webs are stopped, republish multiple times...even reboot my machine and I continually receive the following error message:The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/qlStatement. The InnerException message was 'There was an error deserializing the object of type System.String. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.

How to filter managed meta data column using page query string?

I have two managed term sets as follows: Articles:Downloads Projects:Downloads I am trying to use a content query web part to filter a list based on the above manged meta data column. I want to filter out only "Articles:Downloads" Scenario 1: When I edit the web part and directly set the filter option with the managed meta data column to "Articles:Downloads" it works fine. When I export the web part, in the .webpart file, the "FilterValue1" property has a value "Downloads|9096e43b-555d-4879-9acc-b4ada9ea9910". Scenario 2: I want the web part to get the filter information from query string [PageQueryString:pageType]. So I tried using these options: a) pageType=Downloads      This works but returns downloads under 'projects' as well. (i want downloads only under 'articles')  b) pageType=Articles:Downloads     Does not work and shows no records c) pageType = Downloads|9096e43b-555d-4879-9acc-b4ada9ea9910     Does not work. (This value is the same as one found in 'FilterValue1' of the static web part). c) pageType = Articles:Downloads|9096e43b-555d-4879-9acc-b4ada9ea9910     Does not work. d) pageType = 9096e43b-555d-4879-9acc-b4ada9ea9910     Does not work.   What am I missing here? Can some one please help?

How do you extract data from the xml attachment of an incoming email and set it as metadata in a doc

Hi, I currently have a document library that contains InfoPath forms. As a form is loaded into the document library I need the data to be extracted from the infopath file and then set as properties/metadata of the file. The infopath forms will be sent to the SharePoint site as an email attachment. So basically, an email is sent to the SharePoint server with an InfoPath form as an email attachment. The InfoPath form needs to be extracted from the email and uploaded to the document library and at the same time updating the document library metadata with the infopath form data. This has been done using Visual Studio but can this be done using SharePoint Designer 2010 now that we have upgraded our site to SharePoint 2010? Any guidance will be greatly appreciated! Thanks Michael


Has anyone seen this error before? I can't find any information on it. I am getting it whenever I am using a repeater control with mysql. It's asp.net 2, on iis6. I know the db is fine because I have other methods that are binding fine (only when they return a single row, so I'm not using a repeater in those instances.
