• Visual C++ Calling a new managed DLL from an old Visual Studio 6.0 behemoth

  Our company has several very large projects using Visual Studio 6.0, and I'm creating a new .NET module that will be used with newer .NET products as well as the behemoth dinosaurs.  Converting the old products to use Visual Studio 2005 is not an option right now because of time. Is it possible to create a DLL in Visual Studio 2005 which primarily uses managed code that can be used by a Visual Studio 6.0 application   If so, how   It appears like I can export functions that can be called from a 6.0 app, and I've read articles on how to call managed code from unmanaged code, but I'm not sure how to instantiate ...Show All

• Visual Basic checking properties of folders

  Hi all, I am trying to run some processes to tidy up our SAN storage.  A couple of the things I am struggling with are : 1)   Checking the security of the folder properties to check who the owner is 2)   Checking the security of the folder to check if "Inherit" is ticked 3)   Search a text file for specific text I already have a process to run SETACL to fix ownership and permissions, however this will run regardless.  What I want to do is first check the Ownership and permissions before I run the process. With regards to the 3rd point, the SETACL pipes the results to a text file, so I wa ...Show All

• Visual Basic converting a buffer value

  I am trying to add a 16bit value to my buffer. I have: b(132116) = Convert.ToUInt16(tbHP.Text) where: b is my buffer array tbHP.Text is the numeric value to add to the buffer. The error I get says an arithmetic overflow occured. I am guessing this is because it is trying to set a 16bit value to an sbyte. I don't know how to correct this. Any ideas   Troy, Is the buffer a byte buffer You didn't specify the datatype. Again, you cannot add anything larger than an eight bit entity to a byte buffer - ever.... there are a million ways to do this. dim a as ushort =   Convert.ToUInt16(tbHP.Text) ...Show All

• Windows Forms Opening a form in design view causes a CC checkout

  Hello, Is there anyone here that uses Clear Case integration with VS .NET I'm having a problem that causes a immediate checkout when I open a form in the designer. Does anyone know why double-clicking on a form.cs file in the Solution Explorer causes that file to be "touched" Is there a way I can turn this off so that I can view the visual representation of the form without changing the file attributes to read/write I believe that is why the file gets checkout of Clear Case, because when you edit a locked file, it will unlock it and check it out. But I need to view the design without unlocking the file. Thanks ...Show All

• Visual C++ How to install a Debugger Visualizer for a C++ object in Visual Studio 2005?

  How to install a Debugger Visualizer for a C++ object in Visual Studio 2005 I could happily and successfully follow the tutorial for creating a Debugger Visualizer in Visual Studio 2005 Beta 2 in C#. But there was no information about creating such in C++. How to do it What I mean by creating such in C++ is having an object in a C++ application visualised by a Debugger Visualizer (written in any language). Besides, I'm sure it's possible, becuase Debugger Visualizers is such a great invention and such a large step towards the future of programming, that it would be a terrible waste to not implement it  ...Show All

• .NET Development "Access is denied" errors from CounterSample.Calculate (new with RC1)

  With the RC1 build, I am seeing a new problem that I haven't been able to find a solution to. We have a WinForms app that uses a remote object hosted in a Windows NT service. The service runs as the Local System account. We are sampling performance counters and logging results in the remote object. Because Local System doesn't have the right permissions to read the performance counters (which may be on a remote server), we pass credentials to the remote object. Before it accesses the performance counters, it impersonates a user with the correct permissions. This all worked well with 1.1 and Beta2. But with RC1 it throws an exception whe ...Show All
