.NET Development Registry access problem
I would like to write some application information to the registry 'HKEY_LOCAL_MACHINE\Software'. There is no problem to do that by a Windows application, but when I try to do the same thing with my Windows SERVICE, I get the message; "Access to the registry key 'HKEY_LOCAL_MACHINE\Software' is denied." Why is that and how to solve the problem Thanx.... Apparently the user account under which your service runs does not have the permission to read the key in the registry. Either give the account the appropiate permission or change the service to run under an account that does have the permissions. ...Show All

Visual Studio I really wish someone would help me!!!!!!!!!!!!!!!!!!!!!!!
I can't print my report...I'm new at C# and .net, and this is making me insane... PLEASE SOMEONE.....I have a VERY simple report...and It won't do anything...no errors nothing... I don't see anything wrong with the code since it's pretty straightforward. How are you feeding property settings to the report Do you have a ReportDataSource containing them If not, you might want to try temporarily removing those fields from your report and running it to see if something (the data passed in as parameters) gets displayed. It's a matter of personal preference, but I would use a ReportDataSource based on your transactionData[] class, provided it is a class and not simply an array. It's a shame Visual Studio doesn ...Show All

Visual C++ Accessing files and folders inside projects added to a SolutionFolder (vs2005)
I'm having a hard time accessing the files and folders under projects that are added to SolutionFolders.

Visual C++ How do I fix aspect ratio of CStatic object (MFC)?
I apologize if this question has been asked prveviously: I have created a simple dialog with a CStatic object as picture frame to show JPG image, however when I start the MFC program in different PCs it changes the rectangle size.
