if u want to run ur stuff in 64, there few things that should be taken care.
if u want to make 64 bit application run on 64 bit environment, firstly compile it as 64 bit. And build it, and some API in 32 bit wont work. Definitely you can use registry APIs in 64 application, using which you can modify registry.
If want to port your 32 bit application to 64 bit then
1. Build using vs 2008(64 bit support enabled) is must.

Hi,

I'm looking for a way to determine that XP (or XP embedded) was shutdown correctly. Is there a way to see that in registry or is there som Windows API-calls that can tell me that?.

With Kind regards, Ole

Layered window causing redraw anomalies under itself

Code-o-mat21-Jul-09 22:22

Hey people!

In our program a dialog box is displayed with an edit field and some buttons and above the dialog a layered notification window is brought up, stays up for a while (the user has to wait at that point) and then is faded out (using UpdateLayeredWindow). The problem is that all the controls on the dialog (which was under the layered window) remain undrawn and the dialog looks like it has holes on it where the edit field and buttons are (you can then make the controls be drawn for example by dragging another window over the dialog and then removing it). Any idea why we get this and how we could resolve it? I tried playing with the clipchildren style and also tried using RedrawWindow to trigger a redraw but it did not work, also using a RedrawWindow-like solution is very ugly and problematic because the dialog and the layered window both are brought up by different message handlers from different parts of the code and they generally do not know of each other (and i would really like to keep it that way).

Thanks in advance for any usefull hints, fellas.

_stat function and files before 1970

Hi All,
I am trying to use _stat C runtime method for a file with time stamp before 1970. It simply crashes.Anybody knows the reason?

Note: My time zone is GMT-5.00 (Eastern time [us+Canada]).

_stat uses time which states in the documentation:
The time function returns the number of seconds elapsed since midnight (00:00:00), January 1, 1970

As far as C is concerned, time (== time_t) started on 1st January 1970[^] - your file with an earlier timestamp is obviously blowing the C runtime's mind. It's like saying to a physicist "here's a file from 10 minutes before the universe existed" - does not compute!

I have to ask one question - are file date-times before 1970 actually meaningful? They obviously aren't proper create/modification dates, so why do you need to manipulate them?

With creation and/or modification dates prior to 1970? Really.

OK - what do you need from the _stat function? You should be able to use Win32 functions to determine the values of file attributes that _stat gives you.

By reading your description, it seems your design is a bit wrong. In general, you shouldn't let other classses manipulate the controls on your dialog.
What are you trying to achieve at a higher level ? Why does your class need to add a progress bar on your dialog directly ?

I am getting back to VC++ after a long time. I am using VS 2008 SP1. It is a simple application a button, an editbox (plain) and a richedit box. When i added a control variable (CString) to richeditbox2, a message pops up that i must call this function. The messagebox now does not show again. when i run the program, i get no errors but the dialog fails to load.

I get the following in output window.

<br />
Binary was not built with debug information.<br />

Any info will be appreciated.

Are you calling AfxInitRichEdit2[^] in your application? Not calling that can have the effect you're seeing...

Yes I tried that after finding some help online but it did not work. Still the same problem. I am using AfxInitRichEdit2() inside the OnInitiDialog as first line. I may need to recompile everything. I also tried linking to RichEdit20.dll ( in project setting) but did not work.

I am using Windows Vista SP1 and Visual Studio 2008 SP1. Could it be that the dll is missing. I tried searching for the dll but could not find it.
