Hi.
I'm trying to get the text from the text-editor of another process (VS.Net) but it return nothing.
This is my code:
<br />
HWND hwnd = (HWND)0x008803AC;
<br />
char Data[500];<br />
SendMessage(hwnd, WM_GETTEXT, (WPARAM)500, (LPARAM)Data);<br />
MessageBox(NULL, Data, "The Control Text", MB_OK);
<br />
any idia why the WM_GETTEXT doesn't work ?
Thanx
|

Thanks for the respond.
I've tried both ways: SendMessage and GetWindowText, although GetWindowText doesn't work for controls outside the calling process.
both return an empty string 
Maybe this is because the text doesn't resides on that "special place" and the only way accessing VsTextEditPane is through the COM interface?

That'd be my guess.

Hi,
I have created an MFC owner drawn control (Derived from CButton) that needs to do some initialization after it is created or subclassed. If the user explicitly calls MyCtrl.Create( .... ), I can handle the OnCreate() message in my control, so no problems.
However, if the user attaches the control through DDX, this results in SubclassWindow being called and OnCreate() is never called. I know you can handle PreSubclassWindow() before the window is actually subclassed, but I need to do some initialization after it is subclassed. So Is there anyway in my class to know after it has subclassed a window?
Thanks in advance for any help.

Say I have a binary resource / text file . Is there a way i can embedded this as part of my VC 6 created DLL .
Now I have a similar project which can be compiled as a static library . TO be able to access the resource (.rc)
I need to access the resources by obtaining the Application handle by doing something like
AfxGetApp()->LoadResource
For a static lib this will point to the application that links using this library . Is there a way I can still access my embedded resources ?
Engineering is the effort !

Sorry, I don't mean to hijack your thread but I have a similar question along the same lines.
I want to export a very small class into a dll, which would also contain a .rc file with 30 or so wav files. Most of the tutorials on this website are either just too complicated to understand or are MFC related. In simple terms, how do you create a win32 dll, containing a .rc file and and a class?

I'm not completely sure what your asking as the message as it isn't really clear...
If looking to load a resource from your library and not the calling executable you can use the GetModuleHandle[^] API passing NULL as the module name, this will then return a handle to your library. You can then use the LoadResource[^] API as per usual.

May I ask you all how to make an item moves randomly in a board game pls?
|
|
|
|
|
use rand() to generate two random numbers and set the coordinates of the window using SetWindowPos() .
That's all buddy.
*Of course you will have to set a timer to change the position in a specified interval of time

Hello,
I am trying to understand recursion by using the following example.
<br />
#include <iostream><br />
#include <iomanip><br />
<br />
using namespace std;<br />
<br />
unsigned long factorial( unsigned long );
int main()<br />
{<br />
for ( int i = 0; i <= 4; i++ )<br />
{<br />
cout << "\n i = " << i << endl;<br />
cout << endl << setw( 2 ) << i << "! = " << factorial( i ) << endl;<br />
}<br />
return 0;
<br />
}
unsigned long factorial( unsigned long number )<br />
{<br />
if ( number <= 1 ) <br />
{<br />
return 1;<br />
}<br />
else <br />
{<br />
cout << endl << "number = " << number << " factorial(number - 1) = " << factorial(number - 1) <br />
<< " number * factorial(number - 1) = " << number * factorial( number - 1 ) << endl; <br />
return number * factorial( number - 1 );<br />
}<br />
}
<br />
I do understand that when i = 0, the base case is true, therefore 1 is returned. 0! = 1
When i = 1, the base case is true and 1 is returned. 1! = 1
When i = 2, the base case is not true, so number * factorial( number - 1 ) is returned, which is 2 * factorial( 1 ). 2 * 1 = 2. 2 is returned. 2! = 2
At this point, I have a question. The next line says i = 3. Then it says number = 2. How does number become 2 if i = 3?
Thanks,
Eric

The recursive calls have to complete before the output can be sent to cout. So what you're seeing is the output from the deepest recursive call first.

Hasn't the output already been sent to cout? The program already output 2! = 2 and i = 3.
At the point in the program where i = 3 is output, doesn't that signify the beginning of a new iteration?
Thanks,
Eric

It appears that you are calling factorial() three times within itself (one for the algorithm itself, and two for the cout statements). With all of those cout statements, that may be leading to the confusion.
"The greatest good you can do for another is not just to share your riches but to reveal to him his own." - Benjamin Disraeli

If you are trying to track the stages of recursion with the cout line then I suggest that you minimise your confusion by calling your recursive function just ONCE and storing the result to use in your cout line and to return, I think that this will you help dissect what is going on?
Good luck I´m sure it will just click and you will go "Ah!"

I am now attempting to apply it and I have come across a problem that I can't seem to pinpoint.
I have written the "eight queens" program, but for some reason, I get an infinite loop. I think my base case is ok. Can someone help me figure out what I am doing wrong here?
Thanks in advance,
Eric

Hello everyone,
I'm writing a simple class to handle FTP SEND of a file from a WinCE 4.2 box. I'm having some trouble with the FtpPutFile call. I've tried several FTP servers using a valid username & password and get the same error every time.
InternetOpen succeeds, InternetConnect succeeds, FtpPutFile returns FALSE, GetLastError returns 12018.
The error message 12018 is defined in WinInet.h as follows
#define ERROR_INTERNET_INCORRECT_HANDLE_TYPE 12018
The type of handle supplied is incorrect for this operation.
Any input is greatly appreciated!

Two problems. 1) InternetConnect() return a HINTERNET but you're treating it like it returns a bool. 2) You're passing the wrong handle to FtpPutFile(), you need to pass it the handle returned by InternetConnect().

Hi,
In release mode , the project is searching for MFC42UD.lib file.
Any idea why and where we have to chnge the project settings, because to my knowledge somebody tampered with the settings
cheers,

Dont worry.
I figured it myself.
Somebody has changed the release setting to debug settings.

Hello everyone! 
Am I reading my file correctly?
for (int i = 0; i <= HEIGHT/32; i++)<br />
{<br />
char * curLine = new char[WIDTH/32];<br />
f[x]->getline(curLine, WIDTH/32);<br />
<br />
for (int j = 0; j <= WIDTH/32; j++)<br />
{<br />
<br />
char v = curLine[j];<br />
<br />
if (!f[x]->good())<br />
return;<br />
<br />
if (x == 0)<br />
fputc(v, outputz);
I noticed that if I open the file in Notepad, the character counter says 16, but if I count the chars with my fingers, I only get 15! 
I want to get each line, and then write each character in that line to another file, individually. What's the right way of doing it? Much thanks! 
PS: I've been struggling with this program for more than 1 month... I suck...

Update! I got the main problem away (NULL characters showing up at end of each line)
But now, the last line doesn't get written... Here's the updated code:
for (int i = 0; i <= HEIGHT/32; i++)<br />
{<br />
char * curLine = new char[WIDTH/32];<br />
f[x]->getline(curLine, WIDTH/32);<br />
<br />
for (int j = 0; j < WIDTH/32-1; j++)<br />
{<br />
<br />
char v = curLine[j];<br />
<br />
if (!f[x]->good())<br />
return;<br />
<br />
if (x == 0)<br />
fputc(v, outputz);
Much thanks!
