• .NET Development signedxml and XmlDsigExcC14NTransformUrl

  Can anyone do this line of code in .NET 1.1 and have it work. <code> signedXml.SignedInfo.CanonicalizationMethod = signedXml.XmlDsigExcC14NTransformUrl </code> .NET 2.0 the signedxml does have the Exclusive canonicalization algorithm.  While .NET 1.1 signedxml does not.  So how do I get around this.  Given that .NET 1.1 only provides an implementation of Inclusive XML Canonicalization, I guess, you'd need to use that ( I realise the characteristics are different ) Gudge ...Show All

• Smart Device Development Question on listview (re)population - performance issue

  Hello, I'm new to UI programming in general, and smartphone UI programming in particular. I have a  question relating to performance of listviews. I have a listview object that has around 200 items with 2 columns each. Displaying this takes quite a while when I test it via the emulator (unfortunately I don't have a WM 5.0 device to deploy to and test on) -- to the order of almost a minute before the listview is displayed the first time when run via VS. Also, my code switches between 2 different lists based on a hotkey being pressed. The second list has fewer items and displays fast, but whenever I clear the listview and reload the firs ...Show All

• Visual Basic Basestream.seek

  Hi, I need to read lines backwards in a TXT file with a fixed length for every line. I'm using Dim linetxt As String Dim counter as Integer = -56 'Which is the length of the lines Dim data_r As New StreamReader(data_path) 'data_path contains full path and name for the file data_r.BaseStream.Seek(counter, SeekOrigin.End) linetxt = data_r.ReadLine And this produces good results for a first reading.

• Visual Studio Express Editions executing functions from a string at run time

  So I made a module with a list of functions that make my life easier. I am expirimenting with this sort of thing, and I am trying to make a little command line sort of thing to be used at run time.

• Visual C++ IAddrBook::Address mapi problem

  Hi, I am 'fixing' some poorly written MAPI code. Mostly because the MAPI wasn't being unintialized and realeased properly, also a lot of the code was not checking properly the return values from the MAPI function calls. I have a problem though with the IAddrBook::Address method. The original code was as follows:- if(FAILED(hResult = lpAdrBook->Address(&hWnd, &adrparm, &lpadrlist))) {  // report error cleanup and exit } else {  // continue with other code } But after reading the online MSDN articles it does not mention using the FAILED macro and that the HRESULT should be checked against S_OK for success only ...Show All
