• Visual C++ Suggestions needed whether ON_WM_TIMER should be added to CView class or not

  I want to upate my application's (an SDI app. using VC++ 2005, MFC) view at a regular interval, say at 1sec. using timer event handler. Here five event IDs are set ( using SetTimer(...) ) with five different intervals (one of which is 1sec.). The view needs to be updated after processing some data recived from a device. I am facing some problems while updating view. Regarding this, I want to know the answers of the following questions: 1. What should I use; ON_WM_TIMER of CMyAppView class or of CMyAppMainFrame class of my app. Which one is better 2. I added ON_WM_TIMER to CMyAppView class for testing purpose, but sometimes flicker takes place while updating the view (used InvalidateRect(&MyRect, FALSE) to do this). How can I r ...Show All

• Visual C++ Disabling message processing on a CAXWindow

  Hello, In my 3d environment im rendering a Flash activex object to a texture. I'm also injecting custom mouse coordinates through caxwindow->sendmessagetodescendants. All works ok except that something is still injecting mousecoordinates as well and throwing off Flash on some situations. I tried different window messages like WM_CANCELMODE. Also tried enablewindow(0). All after my custom injection. But to no avail. I'm very much a rookie with MFC/ATL so please bear with me. Any help would be greatly appreciated! I'm afraid the question is outside the scope of this forum. The C++ General forum deals with the VC++ 2005 IDE, libraries, setup, debugger, samples and documentation -- but not the use of all l ...Show All

• Visual Studio Team System CTP5 - Names names names

  Hi What about this scenario: CREATE TABLE [Schema1].[TheTable] ... CREATE TABLE [Schema2].[TheTable] ... Perfectly legal and probably quite common. But the naming scheme for the files added to a DB-project wont permit this am i right Right now I'm looking at an error in my DB-project that I assume is triggered by this. And what about this: CREATE SCHEMA Person CREATE TABLE [Person].[Person] ... This fails too on import. Brumlemann Solution Architect A correction to earlier posts.  Both scenarios you mention are NOT working in CTP5. I know the first one (Table with same name but different Schemas) has been fixed and will work in future drops.  I'll give the CREATE ...Show All

• Visual Basic Convert Days Into Months

  I have used a timespan into my program so that i can calculate someone's age based on the date he chooses as a birth date from a datetimepicker. Now i want to show his age in years and months. Timespan however can calculate the time in days and not months. How can i convert the days to months correctly considering that some years have 366 days (leap years) and not every month has 30 days http://blogs.msdn.com/oldnewthing/archive/2005/04/14/408106.aspx Best regards, Johan Stenberg ...Show All

• Visual Studio Express Editions Is it me or has intellisense been dumbed down for C++ Express?

  I just downloaded the Visual C++ Express Edition for one of my classes after using the Visual C# Express for a quite a while, I went into the program thinking it would be an extension to my already existing program with an added language. To my dismay I found out that it is actually an entirely seperate program, if there is any way to unify the two though, could someone please tell me how, thanks. Anyways, I started using it expecting the intellisense to pop up automatically as soon as I started typing anything, and sadly, It did not. After looking around through settings I was able to find that I can make it pop up by hitting alt-right Arrow, but that is alot of extra keystrokes, that I would rather not have to hit and have it be like the ...Show All

None of the adapters that are currently sold are compatible.

• SQL Server control flow of execution of statement

  is there a way to check to see if the previous sql statement has completely executed before executing the next statement I have a stored procedure that basically has several insert statements. At the end of the insert statements I call bcp to write the table to a text file. The first insert will write a header record into the table. Then it will insert a bunch of records that are selected from other tables and then lastly will write the footer record. My dilemna is that for some reason the first insert of the header record isn't actually happening until the middle of the second set of inserts where it inserts several records from another table. so basically my file ends up looking like this payment record payment record payment r ...Show All
