Re: user breakpoint called from code at 0x7c90120e

I'm having the exact same problem.

I created a test program in Visual C++, and wrapped it with a licensing tool from Softkey.com, but when I run the executable, I get the error

dwwin.exe – Application Error
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0x7c90120e.

Click on OK to terminate the program
Click on CANCEL to debug the program

The folks at Softwarekey.com don't know the answer. Microsoft suggested i disable Dr. Watson (http://support.microsoft.com/kb/188296/en-us), but that doesn't work.

Hi,

I want to list all applications that can be used to open a file based on the file extension.ie "Open With" list when we right click on a file in Windows Explorer. How windows manages this.

thanks

Well, what would you expect? Just provide it with a valid handle.

FYI - the doc page[^] contains an example as well.

I guess... pass a valid handle...?

Can you show how you called RegQueryValueEx?

HKEY hKey = GetRegistryKey(CString ("Connections") );

this has been successful as i have called RegEnumValue and thats working fine.

but problem is with RegQueryValueEx

int t= RegQueryValueEx( hKey, strValue, NULL, &Type,(LPBYTE)rgValue,&size1);

Documentation [^] states:

hKey [in]

A handle to an open registry key. The key must have been opened with the KEY_QUERY_VALUE access right. For more information, see Registry Key Security and Access Rights.

This handle is returned by the RegCreateKeyEx, RegCreateKeyTransacted, RegOpenKeyEx, or RegOpenKeyTransacted function. It can also be one of the following predefined keys:[...]

How to know if LargeAddressAware is set?

wilburke11-May-09 22:27

11-May-09 22:27

On XP / Windows Server you can extend the address space from 2GB to 3GB. Two things are needed:
- you have to use the /3GB option in the boot.ini
- your program should be linked with the LARGEADDRESSAWARE option (could also be set via editbin)
I'm looking for c++ code to find out if both conditions are set.
The first condition can easily checked by looking to ullTotalVirtual from GlobalMemoryStatusEx call.
But I didn't find a way to dedect if the program uses the LARGEADDRESSAWARE option.
MSDN talks about an addressAwarenessType from 'VCLinkerTool Object':
http://msdn.microsoft.com/en-us/library/aa712546(VS.71).aspx[^]
How do I use this in a small C++ program (I'm using Visual Studio 2005)?

I am not sure whether there is an API for this, but you can find this by checking whether the IMAGE_FILE_HEADER::Characteristics variable contains IMAGE_FILE_LARGE_ADDRESS_AWARE flag.

Building on Naveen's answer:

Use ImageLoad[^]:

// Ignore the fact that errors might happen
const bool isLargeAddressAware = IMAGE_FILE_LARGE_ADDRESS_AWARE == ((LoadImage()->FileHeader->FileHeader->Characteristics)&IMAGE_FILE_LARGE_ADDRESS_AWARE);

What exactly do you want to do with Linux?

Basic OS programming - that's all C, really. I'd recommend Advanced Unix Programming[^]. It may say advanced, but it starts with the basics of Unix programming!
GUIs - pick a library, any library...I'd go for Qt, because it's a nice framework, is cross-platform etc. There are lots of others available, though

Creating a PPPoE connection

11-May-09 21:27

Hi All,

Ive spent the last 3 days looking for a way to dial a PPPoE connection using c++ (without having to implement the protocols myself). Ive heard that you can use something already in most linux distro's to create them quite easily, but im at a loss when trying to find information about it. Also, dialing it in windows? Is there any way without having to handle the ppp stack and everything yourself?

Any help would be appreciated.
