  Hi, We found that on WinCE the time_t typedef is unsigned, it should be signed and not unsigned. Also the timeval struct should use time_t. Can MS correct this Johnny ...Show All

• Visual C++ Advice needed

  I have been tasked with providing a front end interface to an existing MFC-based DLL. It is a plain, old DLL - no COM interfaces. The DLL has some APIs that have parameters that involve template types and pointers. The goal of the project is to provide a .NET DLL that acts as a "pass-thru interface" into the existing DLL so new, .NET clients can easily utilize the DLL. My question is, would there be any benefit one way or the other in using C# or Managed C++ for my new front end application thx in advance, todd Yes, I do have access to lib and .h files. However, I'm confused in that if I want a Managed C++ app, it seems like there would be a problem if I compile using unmanaged lib file ...Show All

• Visual C++ adding a watchpoint (breaking when a variable changes)

  How is it possible to add a watchpoint in Visual Studio. A watchpoint is basically a conditional breakpoint that is _not tied to a codeline_. What I want to be able to do is to break whenever someone changes a particluar variable. There seems to be two options: "Watch" a variable and see for myself if/when it ever changes. This is slow, and doesn't really work if you're debugging event/time critical bugs. Debug->New Breakpoint->New Data Breakpoint. This seems to be what I want, but the menu option is always disabled (even when the debugger is running). So how do I do it (I'm using Visual Studio 2005 Professional Edition) espen Run your application under debugger. Then Debug>W ...Show All

• Smart Device Development VisualStudio2005 fails to create SmartDevice MFC apps but works fine with c#

• .NET Development Reading SID's, ACE's and DACL's

  Im building a tool that will periodically check a directory for a number of things, including the permissions that the 'network service' account has, namely whether it has write & modify access or not. Im new to windows security programming, but im working through an example using the .net framework class wrappers. Some of the code im using is listed below. Questions: - Is the first part of a SID going to be the same for a given user name from machine to machine Code that isnt written yet - im going to loop through the access list until i find the account(s) im interested in and then check their FileSystemRights, which is stored as a "OR'ed" string. Question - Is there a better way to refer to system accounts that ...Show All

• Visual C++ N00b wants to manipulate a database with C++ via SQL

  Hello, For my study in Econometrics I need to write a program that communicates with a database. The actual SQL-statements that I will use will - as far as I can see at this moment - not be very complicated, but the communication with the database has to be as fast as possible once the program is running (if the start-up time is somewhat higher, this is not a big problem). The SQL statements I need are mostly SELECT statements, but sometimes also other statements are to be used. The emphasis however will be on SELECT-statements. I would also like to work with multiple recordsets, if that is possible (I know it is in Visual Basic). The database itself is quite large, with multiple tables and sometimes over 10,000 of entries within ...Show All

• Visual Studio Team System Should setting "Deny" permission override Admin priveliges?

  I am trying to limit checkin permissions on a certain branch in our source to only the Admin group. I thought the most expedient way to do that would be set the Checkin/Checkout priveliges to "Deny" for the Readers and Contributors group. However, when I do that, the admin group members are being denied access as well. In fact, if I set "Deny" on any permission for a group that an admin belongs to, that Deny permission seems to override the priveliges of the Admin group. According to the documentation here: http://msdn2.microsoft.com/en-us/library/ms252587(VS.80).aspx , I would expect admin group members' priveliges to be unaffected by setting "Deny" for a group to which the admin belongs.
