How can i block these dialogs from my application
Please help me

Iam very thankful to u r reply
here in my project is runing on port no 5060 we have to check whether the my application running or not if it is there required to notify that
|
|
|
|
|
Open a socket on that port and send a hello signal. If the application is running, it should reply to caller with a standard string.
AKA protocol. Figure out one for your internal use, just as HELO on port 25 is the SMTP greeting.

try to connect to the remote host and look for returned Header!, i.e. if it is Websever it will return some webpage, header etc

I haven't tested the code, so it may have some limitations
I hope this helps you...
Somethings seem HARD to do, until we know how to do them.

A file size is a 64-bit unsigned integer, so your calculation for fileSize will overflow if nFileSizeHigh > 0.
|
|
|
|

Try this
WIN32_FILE_ATTRIBUTE_DATA m_lpFindData;
GetFileAttributesEx("C:\\123.pdf",GetFileExInfoStandard,&m_lpFindData);
DWORD dwSize =(m_lpFindData.nFileSizeHigh*(MAXDWORD+1)) +m_lpFindData.nFileSizeLow;
</code>

Borrowing from WhiteSky's response, but without overflow  ...
WIN32_FILE_ATTRIBUTE_DATA m_lpFindData;
GetFileAttributesEx(_T("C:\\123.pdf"),GetFileExInfoStandard,&m_lpFindData);
DWORD64 qwSize = ((DWORD64)m_lpFindData.nFileSizeHigh << 32) + m_lpFindData.nFileSizeLow;

Hello, I have downloaded this LLMozLib (it allows easy embedding of the Mozilla Gecko HTML layout engine)
but when I tried to compile one of the test apps I got these linker errors:
llmozlib.lib(llmozlib.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)<br />
llmozlib.lib(llembeddedbrowser.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)<br />
llmozlib.lib(llembeddedbrowserwindow.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xran(void)const " (?_Xran@_String_base@std@@QBEXXZ)<br />

llmozlib.lib(llembeddedbrowser.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xlen(void)const " (?_Xlen@_String_base@std@@QBEXXZ)<br />
llmozlib.lib(llembeddedbrowserwindow.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::_String_base::_Xlen(void)const " (?_Xlen@_String_base@std@@QBEXXZ)<br />
llmozlib.lib(llmozlib.obj) : error LNK2001: unresolved external symbol "public: void __thiscall std::ios_base::_Addstd(void)" (?_Addstd@ios_base@std@@QAEXXZ)
The _String_base is defined in the following way:
class _CRTIMP2_PURE _String_base
: public _Container_base
{
public:
_MRTIMP2_NPURE_NCEEPURE static void __CLRCALL_PURE_OR_CDECL _Xlen();
****
Now I found this thread that shows the identical problem and it is suggested that the calling conventions
of the definition and the lib don't match, but the solution (to change __CLRCALL_PURE_OR_CDECL to __cdecl) doesn't work.
I have tried everything to resolve them, but it's no good (god, how I hate linker errors).
I hope one of you guys can shed some light on this.
Thank you.
#edit-> Oh, and I'm using vs8.

hello,
the aim of my program is to move a 50x50 pixel (pic_a) immage over a 500x500 pixel (pic_b) image by moving the mouse over the big image.
also, i have to copy a part of pic_b to produce pic_a and change to rgb color into a grayscale for pic_a. In the end the grayscaled pic_a
has to move over pic_b while exactly matching in content. i know it is hard to explain but i just hope that anybody can give me an idea how to
make a copy, save this and put it into the front. i am using c++ and opengl and think i need several buffers and switch them while moving???
thanks in advance,
patrick

Hi,
I am new at directshow, I am coding in Visual C++ .NET but with MFC. I need to take images which are being stored in memory on the fly and put them into a movie file. The images are being streamed into memory and their is no source filter that allows me to take DIB's stored in memory and put into directshow, unless I missed something.
Do I have to write a source filter that takes images from memory and put it into the directshow pipeline? I am a little lost here, if anyone knows how this can be done it would be greatly appreciated. Also some sample code of doing this would be greatly appreciated.
Thanks

If you want to write your own source filter then the Push Source Filters Sample[^] in the DirectShow
SDK is a good place to start. Very little code needs to be modified.

Hi,
Thanks for the quick response, so do I create a Win32 Static Library Project and then inherit the CSourceStream class, like CPushSource has.
once again thanks for the response.

Thanks Mark,
In Visual C++ .NET is that a ATL Project? I cant find where to make ax the output.
Thanks for your help
|

In the project's Linker settings - output file. Change the extension of the output file to ax.
I don't think this is required - it's just convention (I can't remember off hand )
Remember to change the GUID(s) in the sample code to your own new ones so your filter is unique!
When you have it built you can use the regsvr32 utility to register the com object. Then it will
show up in the list in GRAPHEDIT and your graph builders will be able to find it using your
GUID.
*edit* Note you only have to re-register it if you move it to a different folder.

|

so I create a Win32 DLL Project with no MFC support, and then I change the output to ax file?
Did I get that right?
Once again thanks for all the help.
|
|
|
|
|
Yes
|
|
|
|

Thanks for all the help.
A win32 DLL Project doesnt come with all the necessary files such as the def file, after fooling around I see that the MFC DLL Project does come with def file, am I correct in using that as the project, or have I gone crazy
and I cant see the def file in the Win32 DLL Porject.

There should be one with the sample code. If not here's the contents of one of my source filter
project def files:
LIBRARY MyDirectShowSource.ax
EXPORTS
DllMain PRIVATE
DllGetClassObject PRIVATE
DllCanUnloadNow PRIVATE
DllRegisterServer PRIVATE
DllUnregisterServer PRIVATE
I just checked the sample code - mine is identical except for the LIBRARY name (which makes sense
because I started with the pushsource sample).
I also noticed the sample code doesn't come with a solution or project file for VS. You can
copy the files from the sample folders to your own project folder, rename any you want renamed,
and buld a project for them without problem though. You've already built an empty DLL project so
you should just have to copy the files and add them to your project (including the def file).
They should be built Unicode as well.
