You should probably use a FileStream[^] as it allows you to read the file at the pure byte level. in this way you are free to interpret the data without any assumptions made by the framework. You can also position your file pointer randomly hence avoiding portions of data that you know are corrupt.

It's time for a new signature.

Hi Code Gurus

I need to load the PDF document inside the c#.net Application. I tried with PDF Viewer. If i did any changes in PDF form Field i need to track that also. This is not possible in PDF Viewer. So i need any other Control or Way to load PDF inside the Application.

Please send me the Code snap or project link to resolve this problem.

Thanks in advance..

With Regards

Well Fakeer that is not going to endear you to the forum, asking for the code is frowned upon.

So if you need to edit the PDF you need a PDF EDITOR not a viewer. There are plenty of them around. try doing some research[^]

IQueryable to DataTable [modified]

Is there option to convert from System.Linq.IQueryable to DataTable with some sort of ToDataTable() function, and avoid looping? Both approaches on
http://www.c-sharpcorner.com/UploadFile/VIMAL.LAKHERA/LINQResultsetToDatatable06242008042629AM/LINQResultsetToDatatable.aspx gives me similar speed efect, but I need speeder. Actually I am wondering if there is something like http://msdn.microsoft.com/en-us/library/bb386921.aspx but with using System.Linq.IQueryable instead IEnumerable? I have few functions that sends System.Linq.IQueryable parameter to this function expecting DataTable[] in return.

Best Regards,
Zex

Thank you all, I have similar approach like one in http://peteohanlon.wordpress.com/2008/01/04/extending-linq/, and it is works. But I wonder (because of speed performance) about something like http://msdn.microsoft.com/en-us/library/bb386921.aspx (Creating a Custom CopyToDataTable<T> Method). They said "The existing CopyToDataTable methods only operate on an IEnumerable<T> source where the generic parameter T is of type DataRow. " but wondering is there something equivalent to CopyToDataTable method for IQueryable<T>? Probably not, but maybe somewhere someone offers equivalent method...

I have working function now, but looking for speeding it.

Opening an application through Services.msc

Hi guys,

I've an application and service, whereby when the application exits, the service will open up the application once again. It will be opened as the local account user by the service, instead of system. But somehow the temp folder is pointed to c:\windows\temp instead of the current user's temp folder. This only occurs in Windows Vista and Windows 7, probably due to the new security settings. Can anyone provide me with some help? thank u in advance for your support..

Re: Opening an application through Services.msc

It's because the service wasn't installed under the user's account (it's probably using System, or something like that). Vista and Win7 are more strict about crossing user boundaries.

What you *could* do is make change the app to put its data file in the common program data folder (I forget the exact SpecialFolder to use, but I know you can do it). At that point, any program should be able to get to it.

One possible caveat to this approach is that you may have to write your own code to access the file instead of using the built-in Settings object.

WebBrowser object and the result of an Ajax request [modified]

Hi all,

I'm trying to parse the content of a page downloaded into a WebBrowser control.
I know that I can access the content of a web page accessing the Document.Body.InnerHtml element, but I cannot access the result of an Ajax request that the page makes after (I think) the completion of the page download. I.e., I can access the static content of the ajax request result (the ones contained in the static html page), but I cannot access the dynamic content for example shown into tooltips that appear when I pass the mouse over a control of the page.
I know from the code that is contained into the DocumentStream that the dynamic content (a table) has been already downloaded in a variable (I know its name) and reused each time I pass a mouse over a control of the page using the onmouseover event, but how to get the content of the table?

May I invoke (from C# code) one of the java functions already present in the Document code, that are used to generate the content of the page starting from the table variable? These functions are normally used from the dynamic page to get the html result that normally is used to fill (referring to the example before) the tooltip that appear when I pass over the controls? I could use this functions, if possible, to extract the content of the table that I need.

Any suggestion?

Thanks, any help is very appreciated

Leo

Hi aspdotnetdev,

Thank you very much. Very clear and concrete.
One more request.
How to access global variables of the javascript, or otherwise, how to execute a javascript function that returns the global variable if the javascript function does not exist in the html code of the loaded page?
In this latter case, I could create a custom code to execute a javascript function that returns the content of the global variable or its field if it's a structure.

Thank you very much for your previous reply.
