I need to do it from the code, to attach a debugger to a process id, just the same as we can do it from the task manager when u right click a process and click debug.

Any help would be appreciated

Check out the following API calls:-

<br />
Private Declare Function DebugActiveProcess Lib "kernel32" (ByVal dwProcessId As Long) As Long<br />
Private Declare Function WaitForDebugEvent Lib "kernel32" (lpDebugEvent As DEBUG_EVENT_BUFFER, ByVal dwMilliseconds As Long) As Long<br />
Private Declare Function ContinueDebugEvent Lib "kernel32" (ByVal dwProcessId As Long, ByVal dwThreadId As Long, ByVal dwContinueStatus As Long) As Long<br />

I only have this in VB - I'm guessing you want a C/C++ example...

Thanks for your help
but i already checked these APIs, and the prob is that im not developping my own debugger i just want to attach to the VC++ debugger. whereas these APIs are issued by the debugger.
Hope you get what i mean

Ah. You mean that you want your application to attach the VC++ debugger to it, rather than attach your program AS the debugger.

Will "MSDEV -p procid -e procid" not do this?

If you want to use the same debugger as configured on the system for just-in-time debugging (which I think is the same as the one used by Task Manager), you can find the path in the Debugger value of the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug.

Hi,

i have seen code samples and i would like to know the following

what is the difference or why is it better or why would someone

register a window class and then create a window and then lay a dialog over it instead of just registering the class and creating a dialog?

is there an advantage?

thanks

ps i hope someone understands my question....

I declared a varible as a SYSTEMTIME type in my code as:
SYSTEMTIME st;
how to make its value one minute later or one hour later?

Thank you in advance!

That sounds a little difficult,I think.
You should care about many things, such as the rolling-over problem, including second to minute,minute to hour,hour to day, day to month, month to year and so on, in which you should also consider the leap problem, whether there are 28 days, 29 days, 30 days, or 31 days in a month.
Can you bring out a better way?
Here is one I can't still have enough condidence.
Convert the varible into a FILETIME or LARGE_INTEGER varible, and then increase the new varible's value. At last convert the varible back.
Herein we know "FILETIME structure is defined as a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601", however I don't know the definition of LARGE_INTEGER

Can somebody tell me some better ways or my last quetion?

if you look to the documentation for SYSTEMTIME:

It is not recommended that you add and subtract values from the SYSTEMTIME structure to obtain relative times. Instead, you should
- Convert the SYSTEMTIME structure to a FILETIME structure.
- Copy the resulting FILETIME structure to a ULARGE_INTEGER structure.
- Use normal 64-bit arithmetic on the ULARGE_INTEGER value.

instead LARGE_INTEGER you can use the __int64 on microsoft compilers

The following sentence can work well for your the last five sentences.

In the properties of the menu item.. in the caption field use a \t to "tab" the keystrokes.. like

ID: ID_FILE_NEW Caption: &New\tCtrl+N

Hi,
use CString to show data in RichEditView. Use Format() Function. "/r/n" as new line feeder. Set appropriate properties of CRichEditCtrl.

Disabling the System Menu

If I have a dialog window, I can dynamically disable a button like this...
GetDlgItem(IDC_BWHATEVER)->EnableWindow(FALSE);

But how do I dynamically disable the buttons in the system menu at the top of the dialog?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
