DirectShow == 
But yeah, it can be done with a filter. Take a look at the EZRGB24 sample that comes with the SDK. It would have to be modified quite a bit, but it could be done.

With help of this forum (thanks to good peaople) I learned how to use MSLU with MFC apps (http://www.trigeminal.com/usenet/usenet.asp?1033)
The only thing I need to do to complete my task is to override OleUIPasteSpecialW, changing properly some members of LPOLEUIPASTESPECIALW structure, making LPOLEUIPASTESPECIALA from it and then calling OleUIPasteSpecialA. The problem is in displayng FormatName(s) in listbox. How to get them to translate from Unicode to ANSI using WideCharToMultiByte?
All this required to let the OLE stuff to work correctly in MFC apps in Edit menu->Paste Special.

You have to use WideCharToMultiByte twice, one to know the size needed and one to do the transformation.
LPWSTR lpszMsg;<br />
[...].br />
int iCharSize = WideCharToMultiByte(CODE_PAGE, 0, lpszMsg, -1, NULL, 0, NULL, NULL);<br />
LPSTR formatANSI = (LPSTR) HeapAlloc(GetProcessHeap(), 0, sizeof(char) * iCharSize);<br />
WideCharToMultiByte(CODE_PAGE, 0, lpszMsg, -1, formatANSI, iCharSize, NULL, NULL);<br />
HeapFree(GetProcessHeap(), 0, formatANSI);

I have run into a small problem. I have an application (two of them really, but who is counting) that is trying to send a file across a socket. The code is working great and is in production. Now, we need to be able to send large files ( 50-60 Gb ). When I call TransmitFile with a handle to a large file, I get a 10022 error ("unexpected parameter"). The file that I am trying to send is 4.8 Gb in size. Does anybody know if this call is limited to a file that is less then a 32 bit integer size? I did find TransmitPackets, but that requires Windows XP and that is not acceptable. I am sort of stumpted on this one. For what it is worth, I am doing this in the context of IO completion ports if that matters. Any help would be great.
Thanks

What is TransmitPackets? Is that an MFC function? There are several solutions if you would implement IOCP in Winsock. One is to read and send sections of the file.

TransmitPackets is a Microsoft extension to winsock implimented in XP only.
As for sending the file in sections, that is the only thing that I could think of also. I was hoping that someone could provide a work around that did not take the performance hit.

Sending a large file in chunks via IOCP is actually quit impressive in terms of performance. Winsock could only handle up to certain file size until the CPU has to wait for the NIC to transfer the data.

I have a Doc/View application where I want to put a listview control in the CView derived class. Unforetunately I get the following error when the program runs : "Cannot create a top-level child window" on the two controls that I want in my CView derived class.
Ex
Defined in the MyView.h
CListCtrl m_lstCtrl;
In the OnCreate of CMyView
m_lstCtrl.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|LVS_REPORT, CRect(0, 120, 200, 200), this, 1); <-Error at this point.
What would I be doing wrong? I was pretty sure I could put a child view inside of another childview. As a side note, If I change this to pParentWnd, the list control draws, but the CMyView draws over it.
Cheers,
Clint

I just created a brand-new SDI project, added the OnCreate handler to the view class, and then your code, and it works fine. I then tried it with a new MDI project and it also works fine.
I suggest you try it yourself and check what the difference is.

Does anyone have a sample of how to add/remove a computer from the domain? I have tried DirectoryEntry, but it doesnt seem to delete the computer from the domain controller. All it seems to do is remove the trust to the domain, and it only works when the machine is powered on.
Thanks in advance...

 I have a dll written with Delphi. Certainly I have no .lib, but I know how exported functions are declared in this dll.
Is it possible to make .lib from this dll to link it statically in C-compiled .exe?
Or maybe there is some other way?
|
|
|
|
|
Delphi doesn't give you a way to generate a LIB file for its DLL?
Anyway, if you know the exact signatures of the functions exported, you can then use LoadLibrary/GetProcAddress to call them. It's not fun, but it's the only way I know to do this.

Alvaro

Yes, this is obvious way. This way we link dll dynamically, right? I also think that it is the only way to link dll without .lib. But maybe some one knows the way to make the .lib for it?

I've seen this question asked here before and no one has come up with a solution. Frankly, I don't think there's a way to do it, but hopefully I'm wrong.

Thanks. You have declined me to suggestion that even it is possible, it is probably not worth it!

Yes, I think it can be done, I did something similar a few years ago, before I delve into my notes, they are not very good, do you have the header '.h' file that gives the function definitions, because without it is very difficult.
It is likely to take me a few days to sort it out, and to test it, so let me know, but I won't make any guarantees!

I'm not sure I understand your question but if you're asking if there is a way to create a .lib file from a dll file, I think I found your answer.
Basically, you use the command line executable file called LIB.exe in the Microsoft Visual Studio\VC98\bin directory. Try typing "import library" into the MSDN index and there are several topics there "building", "creating", "using", "linker files", etc. I don't know what the link is for it on MSDN online.
Edit: I found it http://msdn.microsoft.com/library/en-us/vccore98/html/_core_working_with_import_libraries_and_export_files.asp[^]

Yes that was "my" solution, in simple terms, I HAVE NOT TESTED THIS, the info is from my very old notes
dumpbin /Exports mydll.dll
create mydll.def from this, format:-
funct1@4 @42
funct2@2 @43
where func1 is the function name, @4 is the size of the function arguments, in bytes, @42 is the ordinal/
lib /MACHINE:i386 /DEF mydll.def
This next line I am guessing at, the new header file:-
__declspec(dllimport) BOOL __stdcall func1(char[4]);

Thanks for all who help me to find a solution of this task.
After a little correction of Ted's solution, finally I've made the .lib for my dll and link it successfully to VC++ project.
Ted's solution with corrections:
dumpbin /Exports mydll.dll
create mydll.def from this, format:-
EXPORTS
funct1@4 @42
funct2@2 @43
where func1 is the function name, @4 is the size of the function arguments, in bytes, @42 is the ordinal/
lib /MACHINE:i386 /DEF:mydll.def /NAME:mydll.dll
This next line I am guessing at, the new header file:-
__declspec(dllimport) BOOL __stdcall func1(char[4]);

Thanks for fixing "my" solution! I have updated my notes now!

(In a NT Service program, not login) How to get a Asp page's response form the Localhost IIS Server? thanks!

Who can tell me: What changes will registry happen, when IIS Server was not able to response a ASP page request?

Hiya I was wondering how to do this. Myself and my mate work on the exact same project in .NET, but doing different parts of the project each.
What is the best way to update our projects so that we both get each others new parts of the project when we need too...
Thanks,
grahamoj.
