• Software Development for Windows Vista Could I use WWF in such scenario?

  In many business application, some database records should be viewed and modified by many person by sequence. In general, at anytime there should be only one person to modify the record, after this person "commit" his modification, another person could go on to modify the record (on another machine in the network) and when the record is being modified, other person could only view the record. Sometimes the record may be withdrawn or rollbacked to previous node in the workflow and such rollback should be logged. A typical scenario is bug tracking application, or order form process system. I am wondering if I could use WWF in s ...Show All

• Visual Studio Online help doesn't work

  Hi, I'm using Microsoft Visual Studio 2005 (version 8.0.50215.44, Beta 2.050215-4400) and I'm having trouble accessing online help - it seems as though the "Microsoft Document Explorer" can't see the Internet. When I press F1 to see the reference on some C# keyword, for example, I get the error show in ms-help://MS.VSCC.v80/dv_commoner/html/1702ec84-76f9-4a82-9043-9ab8acb8aa5e.htm which is "The information you are trying to access could not be found. Various events could have caused this error." etc. This happens no matter what I search for - it only finds stuff I have locally (like help on help). I access the Internet (with no problems ...Show All

• Visual C++ Running a program?

  I have built a program on calculating the area of a rectangle as the user inputs the length and width. It works fine, however, my question is. If I want to send it to someone, what files from the whole folder do I need to send (.zip ). Also, how will they be able to run it, without a compiler. I can easily run it from: C:\Documents and Settings\Peter\My Documents\Visual Studio 2005\Projects\optut\debug however, as I've seen other programs, they usually have just a simple .exe file.   If it helps, here is the code:   using namespace std; int main() { int length; // this declares a variable ...Show All

• Visual Basic Custom Variable

  Is there anyway to create my own simple variable. I need to be able to store really large integers. The largest number that any .NET type can store is Decimal.MaxValue, or 79,228,162,514,264,337,593,543,950,335. If that's not big enough then you would have to create a type kept more than one numerical variable internally, like say one Int64 for the lower 64 bits and another Int64 for the upper 64 bits. You'd obviously have to provide the functionality yourself to perform arithmetic operations on instances of your type. ...Show All

• Visual Studio Express Editions Linker problem with PSDK

  Hi All, I am by no means an experienced programmer, but have taken interrest in C++. I have tried to create a program that should remote control two or more other applications. I am trying to use FindWindow() to get me the handles of the desired applications. At first I had some (trivial) problems with the LPCTSTR, since I am not that good with pointers. If someone can find it in their hearts to explain a little pointer practices for me, I would appreciate it. Well I managed to compile without getting any compiler errors, but now I get some linker errors that I do not know how to overcome. RemoteELS.obj: error LNK2028: unresolved toke ...Show All

• Visual Studio 2008 (Pre-release) awkward syntax?

  How awkward is the syntax for directly using a foreach statement directly over linq query results: foreach (var x in from e in db.Employees where e.City == "Melbourne" select new {e.FirstName,e.LastName}) {    Console.WriteLine(x); }   This syntax would be possible using explicit dot notation.  Do you think it is better foreach (var x in db.Employees.Where(e => e.City == "Melbourne")) {    Console.WriteLine(x); }   ...Show All
