• Visual Basic Special Characters in XML File

  Hi all, I have a little problem with XML. This XML file is a UTF-8 codeification and most of the times a "tiny square" appears inside the text, I know I can replace the character but I just don't know which character is. Working with VB.NET (System.xml and System.XML.Path), I tried to get the char number but I get two values: 63 and 13 Dim CharWeird As Char = GetChar(xString, 15) ' 15 is the position of the character (zero based) CharWeird = 63 BUT if I..... Dim CharWeird As Double = Char .GetUnicodeCategory(xString, 14) ' 14 is the position of the character (1 based) CharWeird = 13 Not to mention that if I lookup the char inside the string: xString.IndexOf(63) or xString.IndexOf(13) it always returns -1 me ...Show All

• Visual Basic I want to trigger a public sub when a particular dll on my pc is run

  Is there a way to open a vb program and run a piece of code when a dll is run OR actually when it is done running would be better. Thank you, Michael Matlosz Ahh...I wasn't clear enough. Sorry about that. Program "C" uses a particular dll file to export data to program "E" when a user clicks a button found in program "C". When that happens the code exports data into a temporary database, until the next time the button is clicked. I can't change code to program "C" or "E". I have built a third program, "D", to achieve the desired results. BUT to avoid the user having to click a second button in program "D", immediately after clicking button in & ...Show All

• Visual C++ char * to unsigned short *

  hi, I have to pass a string to a function, which takes input in "unsigned short *" format How can I do this conversion Thanks in advance, Prashant In addition to Viorel's (hope I spelled right) comment, if your windows application is unicode ready make use of TCHAR data types and _T macros for string definitions and also use "t" set of string copy and other string related functions. So that your source code will be compilable in both Unicode and ASCII builds. ...Show All

• Architecture Web Service for Bank's internal operations

  Dear All. I am very new to XML Web Services. I read that ther are suitable for connecting different organizations and different systems. But What do you think Is it true logic to use Web Services for inside bank operations: f.e: AddNewCustomer, EditCustomer, DebetAccount. So, in general operatiosn that use "Data Manipulation Language". So, not to use siply Client-Server architecture, there will Client-WebSrvice/s - Database Server. As we know bank's has bunch of records. Are WebServices good candidate for such bunch operations Thanks in advance. Teymur When you look at performance, I think it will probably work, if the webservices are designed right. You should be aware of some requirements: ...Show All

• Visual C# Best way to get around not being able to dynamically cast?

  I'm trying to do something where it would be nice to be able to dynamically cast. I know this isn't possible in C# so I'm trying to figure out the best way around this. Basically the setup is I have a 'Segment' class. Then a have a bunch of classes that inherit from the 'Segment' class. Then I have a Segment collection class that has an ArrayList that stores different 'Segment's. What I want to be able to do is have a method that takes in a Type (which will be one of the classes that inherits from 'Segment') and have it return an array of Segments of that type. Something like this: private ArrayList Segmants; public Segment[] GetSegmants(Type reqType) {      ArrayList thisList = new ArrayList();    &nbs ...Show All
