Hey all,
I'm trying to figure out how to directly write to a device in Windows. Basically, what I'm wanting to do is create an image of a device (specifically, a CompactFlash card that doesn't use a filesystem Windows recognises), store it as a file, modify it and dump it back to the card.
Currently, in version 0.001 of my program, I'm just calling dd for Windows using ShellExecute - this works perfectly, but obviously this isn't exactly acceptable for the final product! (and in the kludgy way I've done it, it locks the whole program and I can't implement a progress bar etc etc)
I'm HOPING it's as easy as using fopen and just treating it like a file from then on (sorry, that's my Unix background speaking)...
Any help would be much appreciated.

How can i stop and notify new device which isn't installed?
I have been programing following but it doesn't work...
Can somebody tell me how...please
following is my code:
==========================================================
BOOL CSPClientDlg::ConnexantStartStop(DWORD NewState)
{
// scan only Media-Classes
HDEVINFO hDevInfo = SetupDiGetClassDevs((LPGUID)&GUID_DEVCLASS_MEDIA, NULL,
NULL, DIGCF_PRESENT);
if (hDevInfo == INVALID_HANDLE_VALUE){
return FALSE;
}
SP_DEVINFO_DATA DeviceInfoData = {sizeof(SP_DEVINFO_DATA)};
DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
BOOL bFound = FALSE;
for(int i=0; SetupDiEnumDeviceInfo(hDevInfo, i, &DeviceInfoData); i++){
DWORD DataT;
LPTSTR buffer = NULL;
DWORD buffersize = 0;
while (!SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData,SPDRP_DEVICEDESC,
&DataT, (PBYTE)buffer, buffersize, &buffersize)){
if (GetLastError() == ERROR_INSUFFICIENT_BUFFER){
if (buffer){
LocalFree(buffer);
}
buffer = (LPTSTR)LocalAlloc(LPTR, buffersize);
}else{
return FALSE;
}
}
if(strcmp(buffer,"USB") == 0){
bFound = TRUE;
}
if(buffer){
LocalFree(buffer);
}
if(bFound == TRUE){
break;
}
}
if(bFound == TRUE){
// it can take some time...
CWaitCursor wait;
SP_PROPCHANGE_PARAMS PropChangeParams = {sizeof(SP_CLASSINSTALL_HEADER)};
PropChangeParams.ClassInstallHeader.cbSize =
sizeof(SP_CLASSINSTALL_HEADER);
PropChangeParams.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
PropChangeParams.Scope = DICS_FLAG_GLOBAL;
PropChangeParams.StateChange = NewState;
PropChangeParams.HwProfile = 0;
if (!SetupDiSetClassInstallParams(hDevInfo,&DeviceInfoData,
(SP_CLASSINSTALL_HEADER *)&PropChangeParams,sizeof(PropChangeParams))){
return FALSE;
}
if(!SetupDiChangeState(hDevInfo,&DeviceInfoData)){
return FALSE;
}
PropChangeParams.ClassInstallHeader.cbSize =sizeof(SP_CLASSINSTALL_HEADER);
PropChangeParams.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
PropChangeParams.Scope = DICS_FLAG_CONFIGSPECIFIC;
PropChangeParams.StateChange = NewState;
PropChangeParams.HwProfile = 0;
if (!SetupDiSetClassInstallParams(hDevInfo,&DeviceInfoData,
(SP_CLASSINSTALL_HEADER *)&PropChangeParams,sizeof(PropChangeParams))
||!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE,hDevInfo,&DeviceInfoData)){
return FALSE;
}
if(!SetupDiChangeState(hDevInfo,&DeviceInfoData)){
return FALSE;
}
}
SetupDiDestroyDeviceInfoList(hDevInfo);
return bFound;
}

Have you looked into accessing it via ODBC using a CRecordset object?

There is also MySQL++, the C++ wrapper for the MySQL C API, which is what I am using in my current project.
I don't know squat about MFC, but it works great with Win32s so I don't see any reason why you couldn't use it.

If you have the data on your webserver I'm assuming you have apache and php running yes? If so you can write a very simple script on the server in php to return the data you want. From your mfc program you can "call" the script using the POST method (very simple - there are many classes here on cp that show you how to do that)

hi,
i was trying to create irregular shaped figures on the desktop,i was able to do that in winnt using
HWND hwnd = ::FindWindow("Progman","Program Manager");
HRGN hrgn = createrectrgn(10,10,100,100);
::setwindowrgn(hwnd,rgn,TRUE);
& it worked fine ,but in the case of win98 the setwindowrgn always returns 0,so i changed the setwindowrgn to a MFC call it returns success but no desired results are seen.
And after all now iam confused over Createrectrgn about what it returns.It is said that it returns the handle to the region ,but is it region on the desktop or current.
I am really lost and confused.
any suggestions will be really helpful.
thanx in advance
regards
udaykumar

You should be able to get at the desktop window by calling GetDesktopWindow() or CWnd::GetDesktopWindow(). This should work across all (non-embedded) versions of Windows.

Hi guys
Long time ago, I had a problem to manage keyboard in a CFormview and I solved using accelerators.
Now I have another one.
When I open a dialog from the CFormview (the old one with accelerators) of my SDI app, I don't know how to manage the keyboard inside it. OnKeyDown doesnt't works.
There is a way to perform the same or similar accelerator's solution?
There is a way to have accelerators for each dialog that I open?
How can I do this?
Thanks in forwarding.

I don't know why this forum software keeps stripping my code.. The following is hopefuly the code as I meant to post it originally:
<code>push((v, (holder1<void* Class::*>){i->standard}));</code>

I have to develop a product for Windows XP using VC++.Net with the following features:
1. It has a installer file. After running the installer file, a connection will be created in \My Network Places
2. Double click the connection, a dialog will be shown to type a username and password in. The typed username and password will be used to authenticate to connect to another computer using 802.1x
After authenticating, my computer will be connected to the other computer.
Any one know what steps I should do to implement this product? Does Windows XP provides API to create a connection with 802.1x authentication or I have to develop a 802.1x client?
I really need your advice.
Thank you very much

I am not a COM expert by any means, but you might find your answer in one of the articles at http://www.codeproject.com/com/#Beginners[^]
I do not know why people have voted your query down without answering it. If you don't know the answer, ignore the question. If the answer is so simple to you then give a pointer, don't vote the query down. Remember, the only stupid question is the one that is never asked.

I'm using WinXP+sp2 and .NET 2003

I am having problems compiling an app that simply includes the following template definition, any idea why?:
<br />
template<> struct get<SQInteger> <br />
{<br />
inline static SQInteger from(HSQUIRRELVM v, int idx)<br />
{<br />
SQInteger p;<br />
if (SQ_FAILED( sq_getinteger (v, idx, &p) )) throw exception(v);<br />
return p; <br />
}<br />
};<br />
Here is the error I'm getting from VS.NET 2003
<br />
\primitives.hpp(18) : error C2143: syntax error : missing ';' before '<'<br />
\primitives.hpp(18) : error C2913: explicit specialization; 'squadd::types::get' is not a specialization of a class template<br />
\primitives.hpp(18) : error C2059: syntax error : '<'<br />
\primitives.hpp(19) : error C2143: syntax error : missing ';' before '{'<br />
\primitives.hpp(19) : error C2447: '{' : missing function header (old-style formal list?)<br />
|

Actually I pasted that in wrong, this is the specialization that is causing me problems:
template<> struct get<sqinteger>
{
inline static SQInteger from(HSQUIRRELVM v, int idx)
{
SQInteger p;
if (SQ_FAILED( sq_getinteger (v, idx, &p) )) throw exception(v);
return p;
}
};

A little more context is need to provide a sure answer, but I'll try my luck. I understand you're specializing a previously defined class template named get, right? If so, please check that the general definition of get is included before the specialization. Additionally, the syntax for a full specialization like yours (assumming you're specializing on HSQUIRRELVM) is:
template<> get <HSQUIRRELVM>
{
...
}Does this help?

Alright so, I have this server, but I want to know the IP address of the client BEFORE I accept the connection...I have a feeling I might need to gain this from the communications layer, but I don't know how, or if there is a winsock function that would help me with this...been trying to just find the damn thing for hours now. Someone please advise?

I think the client's address is present in the SOCKADDR passed to CAsyncSocket::Accept(). See this[^] MSDN link.
