• Visual C++ .NET Applications + Single Instances

  Is there a way in C++ to stop multiple instances of a programs from running Can you check somehow to see if an instance is already running and then not start anotherone Thanks, Michael Usually this is done with named mutex: using namespace System; using namespace System::Threading; int main( array <System::String ^> ^args) { bool createdNew; Mutex^ mutex = gcnew Mutex(true, "AMutexNameThatTriesToBeUnique", createdNew); if (!createdNew) { Console::WriteLine(L"I'm already running !"); return 0; } Console::WriteLine(L"Hello World"); Console::ReadLine(); return 0; } ...Show All

• .NET Development tool for winapi

  Is there any tool that can map the .Net functions with the winapi functions ie when i select the method File.Open(path) to see the api functions that are called. The source code for the base classes (like System.IO.File), the CLR and the compilers is available as a download from MSFT. For extension classes like those in the Windows Forms namespace, you can use the excellent free Reflector disassembler . ...Show All

• Visual C++ bug in short if statement with nullptr?

  Hello! I found a strange thing using the shortend if statement when using a nullptr: This works: OleDbDataReader ^reader = cmd->ExecuteReader(); if (reader->IsDBNull(1)) pObj->DateProperty = nullptr; else pObj->DateProperty = reader->GetDateTime(1); And (just for testing) this works too: OleDbDataReader ^reader = cmd->ExecuteReader(); pObj->DateProperty = reader->IsDBNull(1) reader->GetDateTime(1) : reader->GetDateTime(1); But this is not: OleDbDataReader ^reader = cmd->ExecuteReader(); pObj->DateProperty = reader->IsDBNull(1) nullptr : reader->GetDateTime(2); The last code gives compiler error C2446: ':': Can't convert 'System::DateTime' to 'nullptr' which doesn't make any sense ...Show All

• Visual Basic Unsigned Arithmetic and overflows

  I've had this discussion before with unint64s. Setting what would normally be the sign bit causes an overflow. Now I'm seeing this in unint32s. Dim a As UInt32 = System.Drawing.Color.Black.ToArgb will cause and overflow. Dim a as Uint32 = now.ticks and &hFFFFFFFF will cause an overflow depending in the time. This should not be. What it means effectively is the UInt32 is actually UInt31. MOVL does not care about signed/unsigned. Exactly !!!!!!!!!!!!!!!!!!!! but the entire purpose of declaring a Uint32 is to have that exact same behavior. ...Show All

• Visual C++ error C2039: 'messageMap' : is not a member of 'TCreate<CBaseClass>'

  Hi All, I inherit an existing project that contains old MFC/ATL C++ code. when I compile the code with VS2003, it compile fine. With VS2005, I got 409 errors. I try to concentrate on the C2039 error above. Do you know why I got the error above What are the differences between VS2005 and VS2003 what makes they are so incompatible Thanks. I wouldn't think that Microsoft changes the message mapping implementation without letting its developer community know about it. The MFC code of VS-2005 should be backward compatible with the VS-2003 MFC code. Man... I wish I can re-write this whole darn thing using C# and .NET framework... ...Show All

• Software Development for Windows Vista ic:TimeExpires -- what's it for?

  An InfoCard contains an ic:TimeExpires element, which the documentation says is the expiry date of the card. But CardSpace seems to ignore this element -- for example, even if I set it to Jan 1 1999, CardSpace lets me use the card, with no errors and no warnings. The element is never sent to the Relying Party or the Identity provider. So, what's it for ic:TimeExpires is really just a hint to the user about the expiration date, and is displayed on the card details page. Enforcement of an expired card is really up to the STS which knows the current state of the associated account. If the expiration time was enforced on the client, it could be circumvented by malicious code. ...Show All

• Visual Studio Team System Creating a Project

  Just starting with TS ...created a Project ...added a scenario and even managed to add some work items directly from MS Project, after much editing. At each stage of adding things I looked on the Project Portal - but this didn't seem to refresh in line with new things added. I've now got 98 Work Items in the project - and even after save & exit of Team Explorer - and refresh / reload of the portal - they aren't appearing.
