I'm trying to beat a track and field type game. The game runs on a internet page and requires me to alternately press the 'B' and 'N' buttons :(to gain speed.
Is it possible to write an application that actually sends these characters to the game

Probably. Are the buttons just standard <input type = button> elements, are are they actually part of a Flash, Shockwave, or ActiveX control?

Haven't got a clue.
Here's the link to the game

Notice the paragraph right below the movie:

Visit our Flash Help Page if you have any questions or problems about using the Flash plug-in.

Based on that, I would say to try using SendMessage(WM_CHAR, 'B', 0) to send the keys to that window.

Yes but.......

SendMessage will send the character to the application that i have written. How do i get it to go to the internet page with the flash game on instead?

Hi
Thanks for your continued patience good ideas but......
It still doesn't work.

The SHELLEXECUTEINFO method certainly starts the web page but i couldn't figure out what to do next;

The FindWindow methods also works but it doesn't get my WM_CHAR messages

The method suggested by bdiamond is also not working. Here i created a sdi app with HTML view and used SetTimer is to fire the

SendMessage(WM_CHAR, 'B', 1)
Sleep(100)
SendMessage(WM_CHAR, 'N', 1)

As a check to ensure this was working i put an OnChar handler in there to see my messages working

The funny thing is that when you press charcaters in the view (ie the web page) the OnChar does not catch anything, but the man starts swimming if you pressing the B and N as you are supposed to

Again, thanks for any help

Or you can always put a webbrowser control in an app and set the address and open the page there. then have a button you can press that loops a million times (or whatever) and use a control variable of the ClassWizard-generated class for the browser control and do a sendmessage().

Creating directory..

I am trying to Create a Directory with Path length > 260 Characters..

Windows is not allowing me to create when length exceds 260 characters..The function i used is CreateDirectory().. When I saw the SDK Documentation it said I need to Use Unicode Version of this function for a maximum path length of 32767.

I want to know wht is this Unicode version function is?? Also do i need to change any settings in Visual Studio if i want to use Unicode Functions..

If possible can any one explain me the above with an example..

Thanks
Sudhakar

Yes, you will need to ensure that both UNICODE and _UNICODE are defined. I would do this at the top of stdafx.h before any files are included.

If you don't want to change your whole app to be Unicode, you can call CreateDirectoryW() directly.

Is the file's type associated with your application?

MFC code:

<br />
CRegKey *r=new CRegKey(HKEY_CLASSES_ROOT);<br />
<br />
r->RecurseDeleteKey(".xyz");<br />
r->RecurseDeleteKey("xyzfile");<br />
<br />
r->Create(HKEY_CLASSES_ROOT,".xyz");<br />
r->SetStringValue("","xyzfile");<br />
r->Close();<br />
<br />
r->Create(HKEY_CLASSES_ROOT,"xyzfile");<br />
r->SetStringValue("","file description");<br />
r->Close();<br />
<br />
r->Create(HKEY_CLASSES_ROOT,"xyzfile\\shell\\open\\command");<br />

that was of course association code.
You can also use .reg files during installation.

Look also at this methods:
CWinApp::EnableShellOpen
CWinApp::ParseCommandLine
CWinApp::ProcessShellCommand

PutFile(…) works - GetFile(…) doesn't… ?

DLL heap crash

Hi !

Our customers ask to add a dll from one of there partners to our project. (I name their dll 'rasterdll' to prevent misunderstandings). I got the libs, dlls and header files from them and add the necessary code to our application. There are 2 small parts I have to add, call a configuration dialog and a line by line processing (image processing; the rasterdll requests line by line and returns the modified lines). I have to say the rasterdll is called from one of our dll's.

Ok, now the problem. The dialog appears as expected but shows some errors (displays a math-calculated pattern, but the last 2 lines are destroyed (~10000 bytes))(The creator of this piece of software says that the buffer for this pattern is allocated via malloc in the rasterdll). For testing reasons I try the debug version of the rasterdll which displays the calculated pattern without any error. I go on with this debug version to the processing test. There are 2 situations: Sometimes the application crashes when I clear the buffer I got from the rasterdll (where I should store the input line), sometimes the process works as expected and I got a heap crash when I unload OUR dll (which calls rasterdll).

The rasterdll should be stable because it works in the applications that were made by the creator of the rasterdll. I think that the only problem can be an incompatibility. But we have exactly the same versions from visualstudio. I have no idea how to fix this problem. Debugging is nearly impossible and useless in my code. The config-dialog from the rasterdll is called by one line, no chance to make any mistakes. The creator of the rasterdll has no idea too. Hope anybody has some tips.

Many thanX,
Thomas

Hi!
I've made a post similar to this earlier. Due to misunderstanding I've rebuild the Q.

What could possible be wrong when CFtpConnection::GetFile(…) returns 5 (Access is denied). I know the file exists because I've just successfully made a CFtpConnection::PutFile(…). I'm using the same CFtpConnection object.

How could I have right to write to my ftp but no right to read.

Any tips are helpful…

Can you 'get' the file manually (i.e., without using code)?
