You'll have to buy something that's sold for money. Nobody here is going to share it with you.

However, you could take a look at The Ultimate Toolbox Application Skins[^], which is free for use.

Saving icon to PNG file (GDI+)?

Hi guys,

I'm trying to make a routine that save an icon (HICON) to png file with GDI+

Bitmap* bmp = new Bitmap(icon);
GetEncoderClsid(L"image/png", &encoderClsid);
bmp->Save(L"xxx.png", &encoderClsid, NULL);

So far so good. But when I open the png ... it is not transluctant (semi transparent).
Any ideas why???
And I found that GDI+ has A LOT of problems with icons Frown | :(

P.S. If you have another suggestion how to do this, please share fragment of code.

I'm not sure that you can do this directly as you suggest. Icons are 'special' file types that Windows understands and paints in a slightly different manner to ordinary bitmaps. Take a look at Icons in MSDN for more information.

Create Model less dialog in Class Adlg.cpp

Don't do it that way. Never touch anything from the UI from within a thread, this is a recipe for disaster. Instead, post a custom message to your UI informing it that it needs to close the dialog.
Check this article[^] for more information about thread (a must read for everybody starting to work with threads).

If you have followed the instructions in the article then you can use PostMessage to close to your modeless dialog.

::PostMessage(m_modell->m_hWnd,WM_COMMAND,MAKEWPARAM(IDCANCEL, BN_CLICKED),0);

Make sure that you have added the WM_POSTNCDESTROY handler and override OnCancel just like in the Help and Support article.

Hi,
We need to extract strings from a .EXE file. What are ways to do that?

Re: String table

Use LoadLibrary[^] to load the EXE.
Call LoadString[^] and pass the handle returned by LoadLibrary as the first parameter.

Thanks for the reply.
We have tried these functions but loadstring function requires the string ID. How do we find that? Can you provide any links which have the sample code?

You have to enumerate the resource types and their names (IDs):

EnumResourceTypes()<br />
EnumResourceNames()

If you need to get all strings from executable, than You need dothis:
HMODULE some = LoadLibrary("mylib.dll")
and than
EnumResourceNames(some, RT_STRING, MyStringCB, NULL);

Please note that every string resource is actually a block of 16 unicode strings. So You have 2 options there:
a) interpret RT_STRING by yourself
b) compute 16 string ID's (nStringIDfirst = (nBlockID- 1) * 16;) and call LoadString() 16 times:

BOOL CALLBACK MyStringCB(HMODULE some_library,
                         LPCTSTR resource_type,
                         LPTSTR resource_name,
                         LONG_PTR aux_param)
{
  DWORD startId = ((DWORD)resource_name - 1) * 16;
  DWORD i, endId = startId + 16;
  for (i = startId ; i < endId; ++i)
  {
    LoadString(some_library, i, ...)
    ...
  }
  return TRUE;
}

Can you please explain the various parameters of MyStringCB in more detail.
Loadlibrary is working properly but, We have problem in the EnumResourceNames.
Thanks.
