Yes, definitely! Also check out the BeginPaint()/EndPaint() APIs for obtaining a DC when drawing
in response to WM_PAINT.

No such thing IMO - misworded maybe
You can add buttons to the dialog resource or
CreateWindow()/CreateWindowEx() can be used to create buttons on an already-created dialog.
For the appropriate window class to use when creating controls, see
Windows Controls[^]

Come on, Mark. Put your double-quote fingers up when you ask those questions:
You want to create "dialogs" that look like "buttons?"

For make a dialog you can use of CreateDialog it makes a modeless dialog box.

VS is unable to locate the DirectShow library, probably Strmiids.lib

I have a project using DShow.It works well in VC6.
But when I convert it to VC2005,some errors occur.
Especially,a error like this:
1>d:\program files\microsoft visual studio .net\vc\platformsdk\include\winnt.h(222) : error C2146: syntax error : missing ';' before identifier 'PVOID64'
I thinks there is some wrong in the configuration of the DirectX(9.0b).
Someone would tell me how to config it and correct such error?
Thanks

The error has been resloved.
But another error occured.
It said that could not find such external :
_CLSID_VideoInputDeviceCategory
error LNK2001: _CLSID_SystemDeviceEnum
error LNK2001: _IID_ICreateDevEnum
How to resolve it?
Thanks

When you install the DirectX SDK, it updates the directories in your VS2005 settings
automatically. You may need to do this manually.
The errors you show look DirectShow-related. For DirectShow, you need the platform SDK as well,
unless you're using an old DirectX SDK.
Regardless, in VS 2005, go to Tools/Options Projects and Solutions/VC++ Directories and make sure
you have valid paths to the directX and DirectShow include and library directories in the
appropriate lists. These should be added at the top so they are searched before the include/lib
directories in the VS installation.

its a linker error you need to import a lib file to your project.

I need a browse dialog that can select files that have file paths longer then _MAX_PATH(260).
I've tried using GetOpenFileName, but I get a "File name is invalid" error when I select a file with a name longer then 260 (_MAX_PATH) characters.
Does anyone have a method or know of an existing library/project that can display a browse dialog which can select file names longer then 260 characters?

Windows not support files longer than 259.
TCHAR lpstrFilename[MAX_PATH]="";
OPENFILENAME ofn;
CString pathname;
CString filename;
int nTerm=0;
char stemp[255]={0};
TCHAR *p;
memset(&ofn,0,sizeof(OPENFILENAME));
ofn.lStructSize=sizeof(OPENFILENAME);
ofn.lpstrFile=lpstrFilename;
ofn.hwndOwner=m_hWnd;
ofn.nMaxFile=MAX_PATH*2;
ofn.lpstrFilter="All files(*.*)\0*.*\0";
if(WINVER >= 0x0400)
ofn.Flags=OFN_ALLOWMULTISELECT|OFN_EXPLORER|OFN_LONGNAMES|OFN_FILEMUSTEXIST;
else ofn.Flags=OFN_FILEMUSTEXIST;
ofn.lpstrTitle="GetOpenFileName";
ofn.nFilterIndex=0;
if(GetOpenFileName(&ofn))
{
pathname=lpstrFilename;
if(pathname.Right(1)!="\\")pathname+="\\";
for(int i=0;;i++)
{
if(lpstrFilename[i]==0)
{
nTerm++;
if(lpstrFilename[i+1]==0)
{
if(nTerm==1)
m_FileList.AddString(lpstrFilename);
break;
}
else
{
p=&(lpstrFilename[i+1]);
strcpy(stemp,p);
m_FileList.AddString(pathname+stemp);
}
}
}
}

Windows does support files longer then 259 characters, but you have to use a different syntax.
You have to use prefix "\\?\" with the file name, and use CreateFile.
For more information, look at CreateFile in MSDN.
I've already tried using GetOpenFileName, and I gave it required buffer size which was greater then MAX_PATH, but it still failed.

As KevinXli pointed out, make sure you pass large enough buffers and set the nMaxFilexxx members
of the OPENFILENAME struct accordingly.

Here's example code:
void TestLongFileBrowse()
{
TCHAR acPath[2048] = _T("\0");
OPENFILENAME ofn;
ZeroMemory(&ofn,sizeof(OPENFILENAME));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.nMaxFile = 2048;
ofn.lpstrFile = acPath;
if (GetOpenFileName(&ofn)) {
printf("Path length: %d\n", _tcslen(ofn.lpstrFile));
printf("Path: %S\n", ofn.lpstrFile);
} else printf("CommDlgExtendedError(): %d\n");
}

Are you using the Unicode version of GetOpenFileName()? Only the Unicode APIs support full paths longer than MAX_PATH
