I tried what you have said and it works, but only if the code is in the dialogs .cpp file. The problem is that I am going to put my class in a dll file so i dont need to re-write it for each app. When i put that in the CEdit derived class, and made the edit ctrl have a member variable for my class, it did not work.

Hi, pals!

I copy some codes from a book dealing with registry table.
But I meet with the following errors when compiling. The compiler
says, CRegKey is an undeclared identifier. Here is the following
codes, how to fix the trouble?

CRegKey reg;
char KeyName[]="Software\\Microsoft\\Internet Explorer\\Extensions\\{06926B30-424E-4f1c-8EE3-543CD96573DC}";
TCHAR PathName[MAX_PATH];
TCHAR IconPathName[MAX_PATH];
TCHAR HotIconPathName[MAX_PATH];
GetModuleFileName(0,PathName,MAX_PATH);
strcpy(IconPathName,PathName);
strcpy(HotIconPathName,PathName);
strcat(HotIconPathName,",131");
strcat(IconPathName,",129");
reg.Create(HKEY_LOCAL_MACHINE,KeyName);
reg.SetValue("{1FBA04EE-3024-11D2-8F1F-0000F87ABD16}","CLSID");
reg.SetValue("Yes","Default Visible");
reg.SetValue("VC Knowledge Base","ButtonText");
reg.SetValue(IconPathName,"Icon");
reg.SetValue(HotIconPathName,"HotIcon");
reg.SetValue("http://www.vckbase.com/","Exec");

LockWorkStation. Only supported on NT5+.

Re: Lock NT WorkStation

26-May-02 18:02

Yes. NT5 ( starting Win2K) supports LockWorkStation. But how to do the same in NT4? Something to do with winlogon.exe & GINA(.dll) ?
How do I programmatically lock the workstation in NT4 ?

Hmmmm. See if you have a file called regsvr32.exe in C:\WINDOWS\system32\ or whatever your system folder is.

Second try... Accessing bitmap bits instead of TIFF image data?

Ice-T.Polarbear23-May-02 21:48

Hi again!

Uhm... Apparently I'm not the only one not knowing how to directly access image data in a CImgEdit control. Wink | ;)

(see former thread)

OK, so I thought of another method to do my task of en-/decrypting image data... I can easily copy the the TIFF image into clipboard and get it back from there as a bitmap...

The (so-highly-recommended-to-take-a-look-first :p ) MSDN library told me to use CBitmap::GetBitmapBits and CBitmap::SetBitmapBits to access bitmap image data. As I recognized that this doesn't work and SetBitmapBits just results in a beautifully-but-solely-filled-with-black-pixels bitmap I even found a notice at MSDN (after hard search of course!) that these functions are obsolete and should not be used! Mad | :mad:

The final hint: I should try GetDIBits/SetDIBits to access the bitmap bits. Nice idea... But I'm too dumb to get it work Frown | :(

So, can anyone give me structured information what I have to do in order to use these methods on a bitmap stored in a CBitmap object? All information I found in this and other forums and even (or better 'as expected') MSDN just confused me more than it helped. Confused | :confused:

Many thanks in advance!

Hi,

How to realize the following c code by using MessageBox with same functions.

fprintf(stderr, "Add. Info 0x%08lx ", val);
fprintf(stderr, "%s\n", sense[i].desc);
fprintf(stderr, " %02ld:%02ld:%02ld ", val / 75 / 60, val / 75 % 60, val % 75);

Thanks in advance!
