No, I've seen classes with hundreds of member variables and methods.

Since all controls are derived from CWnd, they each have a Create() method.

MFC/ can't reach edit box with mouse

Hi there.
I have this annoying bug, and I would really appreciate it if someone could help me here.
I have a MFC application, that creates a Property Sheet-Page structure.
The main project invokes the creation of the property sheet and its pages, while the Dialog Page (the resource) and its corresponded class is defined and implemented in a different projct.

The Problem:
===========
The edit boxes in that page/dialog cannot be accessed by a mouse click, but only by tab - toggling between them. Other controls can be clicked by the mouse (e.g. OK button). Also, when I check the dialog with the 'test' option, the edit boxes can be accessed by the mouse.
Other dialogs and prop-pages in the application don't have this problem, but they are defined in the main resource file, of the main application. can this be the problem ?...

Please help me out here.
thank you,
yaron.

p/Invoke memory release

Hi all,

I p/Invoke a VC++ dll in C#, but there is serious memory leak, how can I fix the memory leakage by the VC++ dll caused by P/Invoke ?
(the leakage seem not come from the internal C++ code inside the dll, so I suspect it come from the loading and unloading of the dll in C#)

Thanks

hiho@ll

i'm using URLDownloadToFile to get a file i have to analyze

every time i'm using URLDownloadToFile it downloads the file and saves under the temporary internet files directory

next time i'm using URLDownloadToFile i don't get the actual file, but the temporary file!

so how do i get the actual file?
is there something like force download?
or may i could delete necessary files in the temporary directory
but how i get the directory of the files?

thx@ll

Use one of the url cache functions described here[^].

Yes, use this[^] class to force the download to not be cached.

Detecting Url change on system wide Browser

Hello guys this is my very first question to this awesome community.

I'm trying to intercept url changes in IE to redirect it at need.

I already started using Shell Programming to hook the creation of IE windows (system wide), but i cannot figure how to hook url changes. That's it Smile | :)

Thank you for your help

Maybe i take the problem the wrong way, feel free to comment. My application needs to detect whenever BeforeNavigate is used. (description below)

Fires before navigation occurs in the given object (on either a window or frameset element).

Syntax

void BeforeNavigate( IDispatch *pDisp,
VARIANT *&url,
VARIANT *&Flags,
VARIANT *&TargetFrameName,
VARIANT *&PostData,
VARIANT *&Headers,
VARIANT_BOOL *&Cancel
);

Thank you for your fast answer. I m on that track too already. I'm still Trying to figure out which option is the more viable : hooking or using a BHO to to my needed url redirections

My knowledge is very superficial yet on those matters and i would appreciate any ideas or hints

Problem with RegisterEventSource

Hi. I'm having a problem with logging into my custom key. I've successfully created the key but when I try to log inside it, it kept logging inside the Application key. How can I fix this problem?

//--Start code--
#define SOURCE _T("Simple")
#define LOG _T("SimpleLog")
#define DLL _T("C:\\Simple\\Messages.dll")

int _tmain(int argc, TCHAR* argv[])
{
AddEventSource(LOG, SOURCE, DLL, 3);
HANDLE hEventLog;
hEventLog = RegisterEventSource(NULL, SOURCE);
ReportEvent(hEventLog, EVENTLOG_INFORMATION_TYPE, CAT_2,
MSG_STRIKE_ANY_KEY, NULL, 0, 0, NULL, NULL);
DeregisterEventSource( hEventLog );
)
//--End code--

For my Messages.mc, I copied from the sample in MSDN, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/message_files.asp

For my AddEventSource() function, I copied from the sample also in MSDN, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/adding_a_source_to_the_registry.asp

I can't locate the problem. Am I missing anything? Please help. Thanks

OnMouseMove problem

hiho@ll

i'm using a CStatic control to display some text, which changes every few seconds

i just wanted to stop changing the text, if the user is over my static control, and go on with the changes if the mouse os out of my control.

now the problem:
i'm using the OnMouseMove Event to check if the mouse cursor is over my static, but if the user moves the mouse curser too fast, in or out of my control, the OnMousMove doesn't get executed!?

from the documentation i know that the OnMouseMove doesn't recognize every mouse move

so anybody know a workaround?

thx@ll

yes not all the mousemovementz are captured!!!!!dependz o how fast the user movez it(the messages are sensed/generated in regular time intervalz).....well u can make the Static control bigger,so there is more area!!!!!and the lesser would be the chances the movemove message iz lost!!!!!

Do you mean through the internet?,
If you are in UK, register in the orange.net website. Free sms are available. Or search google for sms free sites, so many of them.

Problem with socket

Hello, i have a problem in the communication between computers with sockets because when i connect with the server i recieve a verification that i am connected but also i want to send the file list of c:\ and i don't know how. Somebody can say me how or write me the esential lines of code.

Thanks you very much.

Hi densitet,

You can send a file, by converting it to the stream of data.
e.g
Machine1 - Open that file, read the content and send it.
Machine2 - Write the recieved stream/data to file, to get your original file.

I think this is the simplest way to transfer the file using socket !

Gud Luck !

Cheers,
Vishal

Thankyou
