• .NET Development Bool write with Interlocked ? (dispose pattern)

  In my application I frequently encounter situation where I would like to use the Interlocked class with bool objects. The most common case that I am encountering is the IDisposable implementation. As pointed out, Dispose is not threadsafe . Therefore, the common dispose implementation pattern is public void Dispose() {     lock (disposeLock)     {        if (!isDisposed)        {           isDisposed = true ;           // snipped        }     } } & ...Show All

• Visual C++ Question about WaitForMultipleObjects() behavior

  I've been reading up on WaitForMultipleObjects() for use in serial communications programming; however, all the documentation I've seen leaves me with one nagging question. My question is this: When WaitForMultipleObjects() is employed to block pending signal activation of 1 of N events, the documentation clearly indicates that more than one signal may be activated during this call. Furthermore, the documentation indicates that the returned value will consist of the lowest numbered event array index for which the signal was active during the call. Thus, it would seem to me that it is possible to return from such a WaitForMultipleObjects() ...Show All

• Windows Forms DataGridView Scroll

  Hi. When I scroll my DataGridView it is scrolled by steps of 3 (or any other number) of rows depending on what is set in Windows Mouse Properties. Is there a way to make it scroll row by row t.e. one notch = one scrolled row. Thanks! Hi, I had the same problem with DatagridView. The solution is: set the focus on this control ;-) This causes, that events are generated. Adam Ps. Well I think, that this the most useful feature should be included in visual designing, what is more, should be configurable and hope that in the future will be included;) ...Show All

• Visual C# StreamReader & Console Apps

• Visual Basic Passing data from form to form in the same project

  Hello, My project have multiple forms. How can I get a text entry from one form and have it display on another Is it also possible to do with Radio Buttons Thank you. There is two ways to get data between forms. 1.  Pass the data in from a parent to a child using properties exposed on the child form, or via a constructor argument. 2.  Use delegates to send a message to the form in question when the data changes The common problem people face here is that they create a modal form ( one that you need to click 'OK' or 'Cancel' before you can do anything on the parent form ), and then find they cannot access text fields, etc.  ...Show All

• SQL Server MSSQL service restart on principal whilst mirroring...

  I have a problem that has happened a couple of times now. I'm in the process of testing our 2005 deployment - Standard edition on 2003 x64 servers for principal and mirror and 2005 express witness. All are pre SP1. Two databases are being mirrored. I have successfully set up mirroring which seems to work fine - but when I restart the MSSQL service on the principal, spurious things happen: The server that *was* the principal before restart database A is in (Mirror, Disconnected / In Recovery) state database B is in (In Recovery) The server that *was* the mirror: database A is in (Principal, Disconnected) database B ...Show All

• Smart Device Development #ifdef for VS 2005 vs EVC 4.0

  What is an #ifdef I can use to determine a compile is VS2005 vs eVC 4.0 Thanks JEK The short answer is that you can't. There is no "emulator" flag because the device emulator is just another device from the IDE's perspective. Devices are only relevant to the deploy and debug operations, the compiler is completely unaware of them. If you wanted to, you could create your own "emulator" configurations within a project, but there is no compile time directive for this. If you wanted to determine at runtime if you were running on the emulator, there is a way to query for the device m ...Show All

• Visual Basic Stopping Alt+Ctrl+Del

  Hi all I'm writting a program for public payable networked computers for playing games. I've got the server/client billing and other stuff like that done. Problem is, when my program boots up, it displays a full screen form (on top of everything), which holds the login/programs they can use/play. I've managed to remove the Alt+Tab, Alt+F4 and other key combinations like that.  Although, i'm finding that Alt+Ctrl+Del still brings up task manager no matter what i do. I have a solution, that on program startup, it renames taskmgr.exe, (and the backup in dllcache), and it works (Doesn't launch taskmgr),  however, there is a window ...Show All
