For performing some write operations in memory allocated by VirtualAllocEx() use WriteProcessMemory() function. Other functions often raise an exception when used to write in memory of another process.

Hi,
I'm working on a SDI MFC application that's coming along good, but I got a frustrating bug.
Double clicking on a file in, for instance, my documents, gives a error message saying that the file cannot be found, and asks me to check the filename spelling and that the file exists. The thing is, the files opens just as it should, I just get this message as a "extra treat".
Any ida on what's going wrong?

what is the difference between (c):
HMENU hMenu = NULL;
and
HMENU hMenu = (HMENU) NULL;
or (c++):
HMENU hMenu = 0;
and
HMENU hMenu = reinterpret_cast<HMENU>(0);
Is cast operator while initializing pointers really necessary?

There is no difference between any of those. They all have the same effect.

I was trying to includeThe nFS Library[^] in my project, but I couldn't do it like the demo application, where he didn't include neither the .h files nor the .lib file into the project.
When I tried to recompile my program with including all the .h and .cpp files of the libraries it worked. 
Since my project is already full with files, so I removed all these files, and included only the .lib file, and recompiled the program. and I got the following error 
LIBCMT.lib(crt0.obj) : error LNK2005: __amsg_exit already defined in msvcrtd.lib(MSVCR70D.dll)<br />
LIBCMT.lib(crt0dat.obj) : error LNK2005: _exit already defined in msvcrtd.lib(MSVCR70D.dll)<br />

When I put /NODEFAULTLIB:LIBCMT, it works fine. But I will need multi-threading for an even more important Library. 
So, what are the consequences of adding that line to the commandline of Linker....... and what can I do to solve my problem without having to add it. Do I have to go back to adding all the .h and .cpp files of the library.... or .
Please help.  ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

This happens when you try to link things together that have been compiled with different settings.
Go through *every* single library that you are linking in and make sure you are using the correct one i.e. multi-threaded. You also need to check the DLL/not-DLL switches are all the same as well.

I can host and communicate with it just fine. The only quirk is that it refuses to use the XP look and feel for buttons and other HTML controls. I have a manifest for my app. Every native/win32 control is correctly themed, so the manifest is obviously correct. In fact, IE's own scrollbar is correctly themed, just not its contents.
What did I miss? 
I am hosting the control in an ATL/WTL project, but I don't think that's the problem. I should also mention that if I load the html file in IE (the "real" browser), UI controls are themed.

This takes a few steps, and I don't think I have code for it handy at the moment, but the procedure is:
Write a COM object that implements IDocHostUIHandler.
That COM object has to be attached (vague term here, this is the part I don't have memorized) to the AtlAxWin that is hosting the WebBrowser control.
In the IDocHostUIHandler::GetHostInfo() method, do this:
HRESULT CFoo::GetHostInfo(DOCHOSTUIINFO *pInfo)
{
pInfo->dwFlags |= DOCHOSTUIFLAG_THEME;
return S_OK;
}The "attach" part is done by querying the WebBrowser control for ICustomDoc and calling its SetUIHandler() method.
Let me know if you need more help, I can try to find some working code for you.

I have implemented IDocHostUIHandler::GetHostInfo() just like advised.
However, the web control does not implement ICustomDoc, but the document object does, which I assume you meant and not the web browser itself. I set ui handler on that interface, but nothing happens. Well not when expected anyway. GetHostInfo is only called when I for example click on the document, which is way too late I imagine.
I'm stumped.  And it doesn't help that it's half past midnight.  Perhaps I do best in taking a break.

Even a very tired man has his moments. I navigated to "about:blank" first, then set the doc host ui handler, and then navigated to my real page. And voilà!
Thank you very much for your help MrMVP Dunn.

The result of the equation below should be 18.056298955613577023498694516971, but I cannot get anything other then 00 and I don't know why. Anyone else know why?
UINT answer = (36883 / 49024) * 24;
|

Integer division of 36883 by 49024 is zero. Multiply that by 24 and you get zero.

I understand that but I cannot find a solution to this problem. If done by calculator it comes out like this;
36883 / 49024 = 0.75234578981723237597911227154047
0.75234578981723237597911227154047 * 24 = 18.056298955613577023498694516971
|
|
|
|
|
Try (36883.0 / 49024.0) * 24.0.
The compiler thinks you're declaring integers, because you aren't including the decimal point.
As mentioned above, integer division of your values results in zero.

How can I read/write registry entries in an mfc dll?
e.g. can I use the CWinApp interface ?
Thanks.

The same way you would in an EXE...with the registry API.

Thanks..
Okay, so I guess I cannot do it the MFC way ?
i.e.
CWinApp* pApp = AfxGetApp();
CString key = "Preferences";
CString f = pApp->GetProfileString(key,....
int l = pApp->GetProfileInt(key, ....
....
?????
