The following example code can be used for loading a BMP file image in any vc++ application.

HBITMAP hbitmap;
hbitmap = (HBITMAP)LoadImage(NULL,"C:\\house.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE);

HDC hmemdc;
hmemdc = CreateCompatibleDC(pDC->m_hdc);
SelectObject(hmemdc,hbitmap);
BitBlt(pDC->m_hdc,0,0,image_width,image_height,hmemdc,0,0,SRCCOPY);

For viewing as a background image in an SDI application the above code can be used inside the OnDraw(CDC *pDC) method of view class.

For loading a JPEG file you can use external JPEG libraries such as the
IJL15.DLL which is freely available.

Have you tried searching the articles here at CP - I'm sure the effort will reward you. FYI there is no Win32 or MFC support for zip files.

I want a format string convert to float, double. Is it possible?
I think it's possible, just look at the edit control DDX with a float data member(in fact, this is a string to float).
However, I dont know how to do this conversion.
Could u help me? Thanks in advance.

static function vc++

12-May-03 16:58

:(Hello!,
I have a problem with static function, to access to member variable at same dialog class, both the static function and member variable are class members.

The problem begin when i try compile a program with a function in a AfxBeginThead instruction with errors. I solve that problem, using a static function, but now i can't access a data member variable, of the dialog class of my project.

Please help me!!!
Thank for your collaboration.

Since static functions do not have an implicit 'this' pointer, you cannot access any member (non-static) functions or data from within the static function. However, AfxBeginThread() allows to provide a user-defined parameter to your static thread function. In this case, you can pass in the pointer to the dialog as the user-defined parameter, and then use that within your thread function to get at the members.

What you usually do is something like the following:

UINT CMyClass::ThreadFunc(LPVOID p) //this is your static func
{
  CMyClass* pMyClass = (CMyClass*)p;

  p->SomeNonStaticFunc(); //access non-static member functions
  p->DataMember = 0;  //access non-static member data
  ...
  return 0; //return your thread exit code
}

void CMyClass::SomeFunc()
{
  AfxBeginThread(ThreadFunc, this); //start your thread function
}

Capturing keystrokes and mouse events/movement

Hi folks:

I am trying to implement a program that can capture what I am doing and communicate with a "PC-wall" to instruct them to do the same.

To do this, I want to capture keystrokes and mouse movements/events and relay them over to the PC-wall.

Any good tutorials on how to capture such strokes and store them in script form so I can send it efficiently over the network ? I would also appreciate pointers to the task of unwrapping such a script to create the "replication scenario".

TIA

Ron

Search for "Real VNC" it's an AT&T program that acts like PCAnywhere and that comes with the full source...

who knows, you can use that program or even you can get the idea from there...

Hope this helps.

Is there a way to enable/disable a button whitout using MFC ? I am not really familliar with this type of operation. I've done it successfully for edit control :

<br />
// Enable<br />
::SendDlgItemMessage(hwndDlg, IDC_KEYPAIRNEWFILENAME, WM_ENABLE, TRUE, 0);<br />
// Disable<br />
::SendDlgItemMessage(hwndDlg, IDC_KEYPAIRNEWFILENAME, WM_ENABLE, FALSE, 0);<br />

and was expectiong something similar for buttons but everything I tried was unsuccessfull.

Thanks.

I going to show you a way to solve all you problems
Get WTL, in it there is a AtlCtrls.h file, in that there are all the standard controls like CButton

Not only is it easy to use but if you look at the code it wraps the SendMessage stuff. Also has a CString class and Arrays which allows you not to use MFC and it makes things smaller. Once you've used WTL you'll never go back to MFC

WTL is hard to find and I dont have the MSDN site, ask the ATL newsgroup they will know

very special help needed..., Looking for a source code

A friend of mine is developing a new TV producion application. He has his own company, and he was working in this area for many years, but rather in design than developing. You can check the sites www.ddrc.net and deepbluetv.com

His new app is finished only for 50-60% now, but it seems that it could break out Sony's bcast (and more). He's also looking for a good talents in this area, but the first problem he has to solve is with his investors. They want to see the presentation (its ok), the source code (he doesn't want to show it all before contract signing, just parts of it) and they also want to see some of his old codes as a reference.

In the old times he was working as a codeveloper of Maya and Xsi, but as the code is a propriety of the owners, he can't get the source (neither of his work) they don't want to give it to him for many "commercional reasons".

So he is looking for a good code, or just parts of a code which can fit the needs, anything about 3D graphics, paint, text, sound editing, tv production, etc.

If there is anyone who can help out with a source code, please contact me at jackye@dracon.sk or UIN 28834215. I don't know what to offer you as repay, I am just a searcher and problem solver. Maybe you can get a good paying job (in Madrid or UK) or any other help. I'll contact yourselves and everything other (the deal) is your business.

Thanks for your patience
Regards
