are you destroying window created by some other thread? in that case DestroyWindow will not work. Did it crash in DestroyWindow or delete?

I found my problem it was that I called the from Parent Window
dlg->DestroyWindow;
and
delete dlg;
but in my class CDialog it was in
void Dlg::PostNcDestroy()
{
CDialog::PostNcDestroy();
delete this;
}
thank you it was a big mistake from me

There should not be any problem with this code. Can you tell, where crash taking you in the code.
There must be something other , you are doing wrong.

It appears that the NT Security protocol is designed to allow or deny access to files in directories, depending on the security clearance of the human user. I have an application, where access would have to be be decided on, not only by human user identity, but also by means of the identity of the application used to access the data. ( e.g. a User must be stopped from opening a file via NotePad, but, may have access through a Bespoke Application) For instance, Banking Software would have to contain a lot of this. Does Anyone have any Idea or observations about this

I'm printing this just off now, but scanning it I got the gist. It appears to be an obvious requirement that Bill gates never thought about! he seems to be pre-occupied with someone getting access to someone else's ascii file, or something that those like CIA could read from a disk they recovered.
About that,I can assure everybody that Bill has been quite successfull, in that a known local forger in my local area was set free from proceedings in such matters as providing forged passports, solely, because after two years GCHQ ( The UK Gouvernments Central Code Breaking Institute)in the UK failed to decript the man's hard disk, and the courts ran out of patience. The good news out of this is, that Encryption doe seem to work! The bad news is, it only seems to work in Microsoft ways!

I'm trying to make my code ANSI, MBCS and UNICODE compatible. All my string literals are wrapped in the _T() macro, and I use all the TCHAR functions when dealing with strings. In ANSI and MBCS my code compiles fine, but when switching to UNICODE I get compile errors. I have defined both UNICODE and _UNICODE. Here is an example:
'CreateFontA' : cannot convert parameter 14 from 'unsigned short [16]' to 'const char *'
and the function:
hfont = CreateFont(lfheight,0,0,0,800,FALSE,0,0,0,0,0,0,0,_T("Times New Roman") );
This tells me the ANSI version is trying to convert a wide char. Yet in the same file:
'wcsstr' : none of the 2 overloads can convert parameter 1 from type 'char *'
and the function:
TCHAR *idx = _tcsstr(tmp,_T("\\n"));
which tells me the functions are the unicode version.
Whats going on?

It looks like _UNICODE is defined after the corresponding includes for CreateFont and _tcsstr.

I had this problem before and I found that there were two versions of the UNICODE definition. Last time I added
#ifdef _UNICODE
#ifndef UNICODE
#define UNICODE
#endif
#endif
and it worked. I did the same this time, but it's a no go. Some things are being converted, others are not. It looks like a TCHAR specific problem but I cannot find the cause.

I advise you to put these defines in your project's properties, and then recompile to make sure that stdafx.h et al picks it up. If the error still persists after that, I advise you to hire an exorcist...

Found it. Some backstreet file had decided to not include stafx and rather include the files for itself. So my #defines were not being picked up.

Thats a New One, Never tried an Excorsist before, but it seems to have worked!
Let's get a new (ANSI Approved) Pragma , like
#pragma (invoke excorsist)
// This Pragma ensures that ( in the Debug Version at least
// that All Bugs will be Automatically Fixed)
Do not Forget however:
#pragma (endinvoke excorsist), or you get:
error C9999: "found end of line before closing pragma statement"

just write
#define UNICODE 1, you work will done!

haha, I did. The trouble was I wrote it in a place where a particular file couldn't see it.

Help!
I'm in the process of switching an exisitng app to use comctrl version 6. In the process it broke transparent support I had for checkboxes. Static text controls still behave properly.
My main window is a CWnd and I handle the OnCtlColor call. It still allows me to change the brush of the checkbox, but not the text colour nor the transparent flag (whenever I use the transparent flag it picks black as the fill).
Any suggestions as to where I have gone astray?
Thanks!

I still didn't get the hang of these. We can add a value like so:
uRetVal |= DV_CENTERALL;
But I want to remove a value also if it is present:
uRetVal ^= (uRetVal | DV_RIGHT) == uRetVal ? DV_RIGHT : 0;
Is the above correct, or is there an easier better way to do it?
|
|
|
|
|
to remove DV_CENTERALL how about
<br />
uRetVal = uRetVal & ~DV_CENTERALL<br />

Thanks for that. The '~' operator is not on MSDN, it's in the index, but the page has a large "Empty Index Entry" written across the top. So I am guessing it is the NOT operator?
|
|
|
|
|
yes, the ~ operator is the Bitwise NOT

I need a function to get time(seconds and microseconds) in windows, like gettimeofday in Linux.
Can you help me?
Thanks

I need to get the microseconds too. What is the function, if exists?
thanks
