No! No one will do your job for you! Please make an effort and came back with questions about specific issues, showing what have you already done, explaining why it doesn't work as you expected and possibly adding a code snippet of the relevant code!
|
|

|

ok I've made the job only just...
but can somebody explain to me the UU-Encoding,
because i.e. the UuEncode method returns an unsigned integer.
I thought UU-Encoding converts Unicode to ASCII.
So what should I do with this "uint"?
The method "UuEncodeLength" returns me the same length...
So I don't see there any differences in their functions...

This is not true; look at its code:
INT32U UuEncodeLength(INT32U nSrcLen)
{
INT32U uDestLen;
uDestLen = (nSrcLen * 4) / 3;
if ( ((nSrcLen * 4) % 3) != 0 )
{ uDestLen++;
}
return uDestLen;
}
Now let's look at what happen:
- if
nSrcLen = 1 then the function returns 2; - if
nSrcLen = 2 then the function returns 3; - if
nSrcLen = 3 then the function returns 4; - if
nSrcLen = 4 then the function returns 6; - and so on...
|

|

sorry my english is not so good...
I've meant that the methods UuEncodeLength and UuEncode are returning the same value...
i.e. if you enter 2 characters they both returns 3.
Example:
12 returns 3...
but real UUencoding must return:
,3(@

You have misunderstood the code:
- The
UuDecodeLength and UuEncodeLength functions get the length of a string as parameter and return the required length of the correspondant decoded/encoded string. - The
UuDecode and UuEncode functions get three parameters: an output buffer, an input string and the length of the input string. They return the number of bytes written to the output buffer, and put on the output buffer the decoded/encoded version of the input string.
I tried this on my PC:
int main(int argc, char* argv[])
{
INT8U in = "12";
INT8U* out = (INT8U*)malloc(UuEncodeLength(2));
INT32U n = UuEncode(out, in, 2);
free(out);
}

Thanks now I understand the Code,
I've to translate the "out" (in my case byte-array) into ASCII (string-array), then it is working.
"12" =(UuEncoding)= ",3)"
thanks Sauro Viti for this dump...

May I suggest you actually read the comments above each of those functions. They provide a functional description of what each function does, and they make perfect sense to me.

Why in Video File -> Sample Grabber -> Null renderer chain setting sample grabber set one shot to FALSE results in IID_IMediaEvent->WaitForCompletion(INFINITE, &evCode) indefinite blocking after media control runs the graph and it needs to wait for copmletion before grabbing any frames?
With limited time interval it returns with 0x80004004 and evCode=0.
If set one shot is TRUE everything works correctly but it needs to run graph every time after a single grabbing.

hi
my custom window inserted in a CDockablePane object does not receive mouse click, while a button or a list box inserted in the same pane receives it. the pane is dragged when i click on the control instead.
what's the problem and how can i resove it?
thx

Please, do not post the same question on multiple forums: that doesn't increase your chances to get an answer but make people wasting their time answering the same things twice.
Thank you!

hi
apologize
i didn't mean that. i thought that i couldn't post the first one in a correct forum. so, i come here and posted in in C/C++/MFC forum.

Don't worry! My goal was not to blame you, but only to make you aware about cross-posting!

I'm not sure that it is the solution, but you can try to add the DS_CONTROL style to your window (see What is the DS_CONTROL style for?[^] for more informations).
You can do it from the Resource Editor: open your dialog and on its properties, set Control to TRUE.
|
|
|
|
|
the pane and the child window created in it are created dynamically, not loaded from a resource!
|
|
|
|

Is there good library that can do it ? Boost? other?

Do you mean an image on a web page that links to another page ?
If so you should look at the HTML DOM interfaces.
Start with IHTMLDocument2.
|
|
|
|
|
thanks for your reply.
Yes, I want to get all the page link and image address in some web page in depth 5.
When use the Regular expression. I find that some error URLwill be got.
|
|
|
|
|
Create an HTML DOM object and use the IHTMLDocument2::write to load the HTML.
Now use IHTMLDocument2::get_images to get a collection of all the images in the web page.
Iterate through the collection to get the IHTMLElement interface for each image.
Now call IHTMLElement::getAttribute with SRC as the attribute name to get the source URL of the image.
Here is an article to help you with manipulating the HTML DOM - Capture an HTML document as an image[^]

Hi,
I am having trouble with VariantCopy() when the source variant is a VT_ARRAY. I have used VariantInit() and VariantClear() on the destination variant as suggested on MSDN but VariantCopy still does not work. It works OK with non-arrays but then thats easy. In the code fragmet below, pValue points to a VARIANT containing array data.
VariantInit(&m_value);
VariantClear(&m_value);
HRESULT hr = VariantCopy(&m_value, pValue);
if(FAILED(hr))
{
TRACE("Failed to copy variant\n");
}
I can't find any useful examples on MSDN. Anyone have any idea as to where I am going wrong?
Thanks
Tony

Its OK, I found the cause of the problem. All the time I was thinking that there was something wrong with the destination variant but in fact it was the source variant that was messed up. I had set the variant type to VT_ARRAY, but failed to say what type of array it was e.g. m_value.vt = VT_R8 | VT_ARRAY.

I'm trying to use the RegEnumValue function, but I can't get the correct values in the ValueName and data fields
Its seems that the enum itself is ok since its runs the correct number of loops and the sizes parameter are correct.
I get the same result again and again in the ValueName valuedata fields.
Thanks in advance for any help
here is the code I'm using
HKEY hKey = NULL;
LONG enumresult = 0;
WCHAR valuename[1024];
DWORD valuenamesize = 1024;
DWORD valuedatasize = 1024;
WCHAR valuedata[1024];
long index = 0;
const WCHAR* subkey = L"Software\\xxx";
if( RegOpenKey(HKEY_LOCAL_MACHINE, subkey ,&hKey) == ERROR_SUCCESS)
{
while( RegEnumValue(hKey, index++, valuename, valuenamesize, 0,
NULL, (LPBYTE)valuedata, valuedatasize) != ERROR_NO_MORE_ITEMS)
{
