I need to write a program which using CBitmapButton class in a dialog box, so I find the sample code in MSDN and put the code into my program as follow:
In my header file(in a CDialog class)
<br />
CBitmapButton btnBitmapButton;<br />
BOOL m_btnChecked;<br />
In my resource header file
<br />
#define IDC_BTN_BMPBTN 1020<br />
In my CPP file
<br />
m_btnChecked = FALSE;
<br />
BOOL CMyDialog::OnInitDialog()<br />
{<br />
.<br />
.<br />
.<br />
btnBitmapButton.Create( "", WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, CRect(200, 200, 10, 10), this, IDC_BTN_BMPBTN );<br />
<br />
if( ! btnBitmapButton.LoadBitmaps(_T("MYBUTTONU"), _T("MYBUTTOND")) )<br />
{<br />
TRACE0("Failed to load bitmaps for buttons\n");<br />
AfxThrowResourceException();<br />
}<br />
<br />
<br />
btnBitmapButton.SizeToContent();<br />
.<br />
.<br />
.<br />
}<br />
In Event Handler
<br />
void CMyDialog::OnBtnBitmapButton()<br />
{<br />
if(m_btnChecked)<br />
{<br />
btnBitmapButton.SetState(FALSE);<br />
m_btnChecked = FALSE;<br />
}<br />
else<br />
{<br />
btnBitmapButton.SetState(TRUE);<br />
m_btnChecked=TRUE;<br />
}<br />
<br />
}<br />
After compile and run the project, the codes above runs well, but there is a problem which I need the bitmap displays with transparent, and I can only use BMP format picture, so use a GIF transparent picture is not an option, I know how to load a bitmap to a CDC object, and know how to make it be a transparent bitmap, but I just don't know how to put this transparent picture on the CBitmapButton object.
I had search articles about how to implement a tranparent bitmap button both on CG and CodeProject website, and also find some articles which might useful to me, but those codes are all too complex to me, and I don't have time to check the code to figure out how I can use them.
I think I might need to create a class that inherit from CBitmapButton, then override the DrawItem member function, but I didn't have any clue to tell me how to override it.
So, does any one can tell me how to use CBitmapButton class and can use a transparent picture which doing transparent job dynamically?

If you're able to convert the .gif image to a .bmp, you can use this[^] button class if you add the .bmp to your app's resource.

Thanks for your help, I had downloaded and tested, it's a really good button class, but it's like all the other classes, it's too many function, but I just want my button can act like a CBitmapButton and can use a bmp which make it transparent by myself, so if I want to fetch some codes that I really need, then insert into my project, it would cost too much time, because I still not familiar with MFC, and the time I have is too less, so, I need a component which simply for single subject for me to use, otherwise, override maybe my best choice, if there is any one can tell me the way, but thanks for you help anyway

Actually it's easier to use than a standard bitmap button. All you need to do is add a single line of code in your OnInitDialog() method to set the FooButton instance's bitmap. The demo program source illustrates this.
btnBitmapButton.setBitmapId (IDB_MY_BITMAP);

Call CheckDlgButton() in your dialog's OnInitDialog() method.

Call EnableWindow() to disable the check box(es).

// You could use one of the many versions of spawn to pass arguments to an executable that you spawn.
#include <process.h>
_spawnlp(_P_WAIT,"notepad.exe"," c:\\temp\\SomeTextFile.txt",NULL);
// Or, you could get fancy and use ShellExecuteEx
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "notepad.exe";
ShExecInfo.lpParameters = "c:\\temp\\SomeTextFile.txt";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);

i tried as
SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c:\\pkunzip.exe";
ShExecInfo.lpParameters = "-d NewFolder.zip";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
but it didnt work

Don't forget to include the path to NewFolder.zip

Well, I know that, please just tell me once, don't say so many times! What are these messages? Can I turn it off? Thanks for your help.

the messages tell u the specific module is being loaded, no symbol file means u couldn't switch in that module's code, and debug step by step.

Hi all,
Would you help me to change the default sound device with an api or something else...
I do not need the entire application, only the api if possible.
Thanks...

AFAIK it's not possible. There was a registry hack in XP but I can't remember it (Google
it maybe).
From what I've read, Microsoft states this is intentional - so software can't override user
hardware settings.
Also, Multimedia APIs and DirectSound let you pick devices anyway, so I suppose it's not
necessary.

First of all, please forgive for my english. Here's my problem.
I use Visual C++ 6.0 with MFC. I've 2 independant Dialog based projects. I'd like to re(use) the 2 dialog boxes in a new MFC project, without having to retype all the code and the ressources. Is it possible to integrate existing projects into a new one? Thanks.

Retyping would be extreme - you could, at the very least, copy/paste the code (that's code
reusablility!).
There's a variety of ways, here's a few:
1) copy/paste (bad - if you fix/change one then you have to remember to change all copies)
2) Keep a separate folder of common code/resources that can be shared by projects
3) Compile common code to a static library
4) Compile common code to a DLL
Resource files allow including other resource files. To share with MFC you'll need to set it
up so resource IDs don't clash anywhere.

Thanks a lot for your answer. But can you tell me how to use more than 1 ressource file in a MFC project ? Thanks
