I have to change the standard MFC icon located in the top left portion of the main window to another icon.
|
|
|
|
|
Simply provide a new .ICO file in the res folder.
|
|
|
|
|
I have a file which is a type Icon, I have placed that in the res folder.
Does it have to be .ICO?
Once I place the file in the res folder, how do I actually import it in my program so it replaces the IDR_MAINFRAME image of MFC?
|
|
|
|
|
Note the name of the current IDR_MAINFRAME icon (e.g., myproject.ico). Delete that file. Rename your .ICO file to the name of the old (MFC) file. Recompile.

Hi,
Here is the way to change the icon programmatically,
CSomeApp::InitInstance()
{
...
...
pMainFrame->ShowWindow(m_nCmdShow);
pMainFrame->UpdateWindow();
HICON hIcon = LoadIcon(IDR_CHANGED);
pMainFrame->SetIcon(hIcon, TRUE);
pMainFrame->SetIcon(hIcon, FALSE);
}

yeah you can use that.
I always use the constructor of the dialog:
CDlgDialog::CDlgDialog(CWnd* pParent /*=NULL*/)
: CDialog(CDlgDialog::IDD, pParent)
{
//{{AFX_DATA_INIT(CXyKeyGeneraterDlg)
//}}AFX_DATA_INIT
m_hIcon = AfxGetApp()->LoadIcon(IDR_ICONNAME);
}
just change the IDR_ICONNAME to your ico's inserted name.
but it's all the same actually.
Btw, do you know any websites where i can download seperate .ico files like the 'key' security icon?
Greetings

Hi!
I am new to socket programming. When I open a socket to a TCP server, is there a way to detect data whenever it's coming back?
Please help!
Thanks
|

|
|
What I/O model does the server utilize? Under a non-blocking I/O model, the server either monitors the socket. Some I/O models such as WSAAsyncSelect utilizes a process message queue to update a thread on socket activity.

Look into the select() api call. You can detect a pending receive either blocking or unblocking in a loop based on the timeout value you specify.

Somebody can help me?
I need to declare a pointer to a class prior to defining the class.
I'm programming in Visual C++ 6, the code is something like this:
// header file A.h
class A : public CObject
{
....
}
// header file B.h
class __single_inheritance MyClass;
class B : public A
{
MyClass * m_pMyClass; // error C2027
.....
}
// header file C.h
class C : public Object
{
B * m_pBdata;
}
// header file MyClass.h
class MyClass : public C
{
.....
}
But, it doesn`t work, when I compile the code, Visual c++ give me the next error:
C2027: use of undefined type MyClass
Please, I need help,
Thanks a lot.

Just do a forward declaration:
class MyClass;

I didn't find anything necessarily wrong with your code except for the inclusion of a few missing .H files.
At the top of B.H, you need to include A.H, since class B is derived from class A.
At the top of MYCLASS.H, you need to include C.H, since class MyClass is derived from class C.
That's all I had to do to your code to clean up the compiler errors.
Make sense?

I have a Browser Helper dll that disables the context menu in IE and also several of the Accelerator and 'F' keys. I use a keyboard hook to trap for the keys and that includes F1 (Help).
The F1 trap doesn't work. The Windows Help comes up anyway. Is there a way to disable the help from coming up?
I guess I can look for the WM_HELP message, but have not done this type of thing in a dll before. Anyone have any suggestion please? Thank you very much.

Try two things:
set the hook as a low level hook: WH_KEYBOARD_LL / LPKBDLLHOOKSTRUCT (find more in MSDN).
and if this don't work, then set it as a SYSTEMWIDE HOOK: hHookKeyboard = SetWindowsHookEx(WH_KEYBOARD_LL, HookKeyboardLL, hInst, NULL);
Hope this helps.

Hi Joan,
Well, I found the answer by chance and it was quite simple. I didn't realize a DISPID_... existed for this event. I updated my Invoke method to include:
<br />
case DISPID_HTMLELEMENTEVENTS_ONHELP:<br />
pvarResult->vt = VT_BOOL;<br />
pvarResult->boolVal = FALSE;<br />
break;<br />
This did the trick. BTW, I had tried the Low Level hook but it never got called. I'll keep the SYSTEMWIDE HOOK suggestion for future needs. Thanks.

Is there any way to programmatically disable Visual Styles for an application so that it looks normal under XP like it would in previous versions of the OS?

What's the easiest way to read the width and height of a png file using C++ it’s the ONLY image type I'm going to read so massive image libraries are a waste of space in my program. Any ideas?
Cheers

I'm having trouble getting understanding the header information. It doesnt seem very clear to me however regardless of that, how can i change my four bits stored in 4 indexes of an array into a recognisable number? I'm not much good with bit shifting

Do you have a code snippet of what you are trying to do?
|
|
|
|
|
Sure.
The basic idea here is that its going to create a button for a menu in directx. Its gotta find the size of the button image before it can create the panel to texture the png file onto [hence the panel and graphic are the same size] All I need for this is the width and height. DirectX can do the rest.
<br />
std::ifstream data_file;<br />
data_file.open("filename.png", std::ios::in | std::ios::binary);<br />
<br />
char signature[8];<br />
<br />
char width[4];<br />
char height[4];<br />
<br />
data_file.read(signature,8);
<br />
<br />
data_file.read(width,4);<br />
data_file.read(height,4);<br />
<br />
int texWidth = (int) ((width[0] << 32)+(width[1] << 16)+(width[2] << 8)+width[3]);<br />
data_file.close();

OK heres a better one since I just solved one problem and got another...
<br />
std::ifstream data_file;<br />
data_file.open("filename.png", std::ios::in | std::ios::binary);<br />
<br />
char signature[16];<br />
char width[4];<br />
char height[4];<br />
<br />
data_file.read(signature,16);<br />
<br />
data_file.read(width,4);<br />
data_file.read(height,4);<br />
<br />
int texWidth = 0;<br />
for(int i=0; i<4; ++i){<br />
texWidth <<= 8;<br />
texWidth += width[i];<br />
}<br />
<br />
<br />
data_file.close();<br />
Now it says the width of my image is -56!?

Did you mean to use both of these or just one of them?
