Hi, I am using namespace "Microsoft.Practices.EnterpriseLibrary.Logging" to create my application log. My app.config file looks like this:

I gave log file name as "C:\Data\Logs\SRM\SRMService.log". Now SRM folder is being created, but SRMService.log file is not being created. Please tell me where I am going wrong? Thanks SRM

Thank you Rayhan. I'll look into them. Thanks Sai

Hi, I am developing an application which has a WebBrowser control. By default WebBrowser uses Internet Explorer rendering engine. Can we change it to Firefox or Google Chrome? Thanks Sai

Hi, I am developing a C# based desktop application which has GUI developed using WPF. My application has some SQLite database where I save users data. 1) Now I want to place this database in the Cloud so that if user lost it in local device, it can be fetched from cloud from anywhere. 2) Every time whenever local database changed it should be synchronized with data which is there in Cloud. i.e., there should be bidirectional synchronization. Now I have two options. One is Windows Azure and other is Microsoft Sync Framework. Please tell me which one I can go for now? Though Windows Azure is not free, I can go for it. But is it useful? Since my application is C#/WPF desktop application, can I go with Azure? Any help please? Thanks

Guys, I am a software developer and want to improve my design skills. Anybody suggest me some good books on Software Design and Architecture? Thanks MSR

Hi Micro Virus, thanks for your reply. I want to know are there any APIs available in WinRT to 1) Find WLAN interaface list (Win32 API - WlanEnumInterfaces) 2) Find Wi-Fi access points (Win32 API - WlanGetAvailableNetworkList) Basically I am trying to write an WinRT application to do all these. Any help? Regards, Sai

Hi Richard MacCutchan, thank you for your reply. I changed my code like this.

dwResult = WlanOpenHandle(WLAN_API_MAKE_VERSION(2, 0), NULL, &dwCurVersion, &hClient);

But still its throwing the same error. Basically I'm trying to find Wi-Fi n/w interfaces and trying to get available Wi-Fi access points. If I run this code from a pure Win32 application, I am able to get the interfaces and Wi-Fi access points. But not working from WinRT App. Regards Sai

Hi, I am trying to call Win32 API from Windows Store App. Since Win32 APIs can not be accessed from WinRT, I have written a Win32 Dll and exposed a function. I am trying to call this function from WinRT App. But I am getting 'Access Denied' Error. Dll Code:

extern "C" __declspec( dllexport )INT32 ScanWlan()
{
// Declare and initialize variables.

HANDLE hClient = NULL;
DWORD dwError = ERROR_SUCCESS;

DWORD dwMaxClient = 2;
DWORD dwCurVersion = 0;
DWORD dwResult = 0;

dwResult = WlanOpenHandle(dwMaxClient, NULL, &dwCurVersion, &hClient);
if (dwResult != ERROR_SUCCESS)
{
WlanCloseHandle(hClient, NULL);
wprintf(L"WlanOpenHandle failed with error: %u\n", dwResult);
return 1;
}

I am able to call this funtion from WinRT App. But 'WlanOpenHandle' function failed with error 5 (ERROR_ACCESS_DENIED). I have done this using administrator login also. But still I am getting the same error. Am I doing the right thing? Can We access Win32 APIs from WinRT Apps through Dlls (at least). Any help? Thank you, Sai

Hi, I want to know what compiler does WDK 7 use to compile files when we try to build any WDK sample? Regards msr

Hi, I have a sample OSR USB board and I have written a sample driver for this USB board. I have built this driver and able to install. But I am not able to debug this driver using Windbg since it is kernel driver. OS: Win7

#include ntddk.h

DRIVER_UNLOAD DriverUnload;

void DriverUnload(PDRIVER_OBJECT pDriverObject)
{
DbgPrint("Driver Unload\n");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObject, PUNICODE_STRING pRegistryPath)
{
pDriverObject->DriverUnload = DriverUnload;
DbgPrint("Driver Entry : Hello Windows Device Driver World!\n");
return STATUS_SUCCESS;
}

Can anybody help me in debugging my driver?

Hi, I have a Edit Box. How can I restrict this Edit Box so that it will accept characters like '=' and ';' This is not MFC based. Win32 only. Thanks in advance.

Ya I got it. Thanks Richard MacCutchan

class Filter;

typedef void (Filter::*PFN)();

class Filter

Hi, I have tried this. I am getting some junk value. Why is this happened? :( Regards msr

class Base
{
public:
Base() { }
virtual void foo1() { }
virtual void foo2() { }

} ;

class Derived : public Base
{
public:
Derived() { }
void foo1() { }
void foo3() { }
} ;

int _tmain(int argc, _TCHAR* argv[])
{
Derived * d = (Derived*)new Base() ;
d->foo3() ;
return 0;
}

In above code, 1) How it is possible to call foo3() of derived class. 2) If I call d->foo1(), Base class foo1() is getting called. I am not able to understand this. Please explain. Regards msr
