问题 I am using a third-party, proprietary DLL for which the source code is not available to me. Wrapper code that appears to have been auto-generated using SWIG 1.3.39 is, however, available to me. The wrapper code consists of a C++ file that compiles (using some headers that describe the DLL) to a DLL and of a C# project that makes PInvoke calls to the C++ wrapper DLL. After inspecting the StackTrace I got the following information: at org.doubango.tinyWRAP.tinyWRAPPINVOKE.MediaSessionMgr

问题 This will be my first time reading a PDF. I was searching around and found so options to do that with C# and choose to use iTextSharp.

PdfReader reader = new PdfReader(iPDF.Text); for (int x = 2; x <= reader.NumberOfPages; x++) { iResult.Text = Encoding.UTF8.GetString(reader.GetPageContent(x)); break; } As you can see it is a very very basic code just to read the 2nd page of the PDF into a text file

If something untoward happen (such as the socket is unexpectedly closed) how should that thread notify it's "parent" that it's about to end?

问题 I am connecting to a Microsoft Active Directory server in a DMZ from my .net application (asp.net VB .net 4.0). I need to create a new "inetorgperson" in an orgunit called "SingleCustomerAccount".

问题 I'm looking for a way for my users to click on a row on my DataGrid where if that click anyway they would pick up the UniqueID column, and then open an new page which would be called "uniqueidview.aspx" that uses the UniqueID as it's primary key in a MySQL query.
