Do you want to disable it permanently or just while your program is running?
To disable it permanently, you might have to write to the registry or use SystemParametersInfo(), although unless your program is specifically to change the screensaver, then most users won't like you doing this.
To disable it temporarily, look at SetThreadExecutionState(ES_DISPLAYREQUIRED). This function is supported on Win98 or later.
Hope this helps,

Oh, you want to start the screensaver running whenever you like? A screensaver is just an exe file on your hard-drive. The name of the screensaver file the user has selected is in the registry, at "HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE". Read this value and pass it to ShellExecute() and that will run the user's screensaver.
Hope this helps,

Almost, it is actually a .scr, which is, as you pointed it out, a .exe renamed in .scr.

The temperature is about 10 degrees, it's raining, and I'm hungry. I have no idea what colour the sky is because I can't see it - all I see is more clouds than there are people in New York, and I'm hungry.
PS. Did I mention I was hungry?

If you want to start the currently configured screensaver, try this:
PostMessage(GetForegroundWindow(), WM_SYSCOMMAND, SC_SCREENSAVE, 0);

hi all,
i need to check if a file is in use/locked.
(then i have to delete the file if i want.)
how can i do it using win32 api?
regards

If the file exists but you can't open it for exclusive read access, you can safely assume it's locked by another process. Assuming you're using MFC, see CFile for more information.

Hi,
thanks, but i don't want to use CFile.
After checking i want to delete the file.
Is there any win32 way ? I've read now that CreateFile can check this. But is not sure about the arguments.

HFILE hFile = OpenFile(..., OF_SHARE_EXCLUSIVE);
if (HFILE_ERROR != hFile)
{
DeleteFile(...);

I have followed the instructions for C. Lung's VERY helpful article from 1999 on calling a VB ActiveX Dll from c++. I have built my VB dll that I have (which has 24 classes and 1 .bas file), and I used the midl compiler to compile the .idl file that I made by copying the code crom OLE View, as the article instructs. Now that I have the .idl files and the .c files which correspond to my VB DLL loaded into my C++ project, I get the following error when I try to build (F7) my c++ project.
"fatal error C1010: unexpected end of file while looking for precompiled header directive". I cannot figure out the cause of this error.
The only thing I have done that was not mentioned in Lung's article is change some data type specifications in the idl file which were causing error messages from the midl compiler. I changed "Single" to "float" and, I replaced the name of a VB enum I had created with a "Long" data type.
Please advise, or ask more questions, if I have not provided enough info.
Thank you VERY much, in advance, for any help you can provide!

The product I'm working on is still in the stage where I'm releasing debug builds. I have asserts in place for things that I want to see, but aren't actual application failures. What I'd like to do is augment assert so that places where I want to see an assert, I'll get an assert, but not when a debug build leaves my desk. I could just add a define and have not only a debug build configuration, but also a private debug build configuration. But ideally, I'd like to detect at runtime whether the app is running in the debugger or not, and key this behavior (and a few others I won't go into) off of that information. Does anyone know a way to do this?

You should never do that
(and btw. I think it's not allowed to redistribute the debug runtime dll's...)
Here on CP you'll find some tools how to convert your _ASSERT's into release-build log file entries. It's better, really.

Hi there, now I have a problem with my buffer.
I have a buffer reading in data from the serial port data is passed into the buffer like this
m_serialbuffer += ch;
Now this works perfectly for the first string that is sent to the port and stores it. For subsequent strings though, no characters are added. Any ideas??

Is there a chance for the NULL character '\0'? CStrings are NULL terminated.
