Hi Christian 
MySoundTemplate * pSound = new SoundTemplate[lLoop];
This code won't work ...
I must use of STL vector ...
Thanks ...

Not unless SoundTemplate is derived from MySoundTemplate.
MySoundTemplate * pSound = new MySoundTemplate[lLoop];
will work if MySoundTemplate is a class this line can see.
I must use of STL vector ...
It's better anyhow. You should consider how you will use the list, list may be a better option.

Yes, yes, i know ...
My wrong was in typing ...
I mean:
MySoundTemplate * pSound = new MySoundTemplate[lLoop];
This code won't work, too.

There is no reason in the world for this not to work, maybe you should tell me what the errors are ?

Just in case you missed the advice, I'd recommend STL vector (or perhaps list), unless the cost of copying a 'MySoundTemplate' objec tis very high (in which case vector can be expensive).

Hello, the codegurus around the world.;)
How about CPtrList or CPtrArray?
I think that these also works.
Have a nice day!

How to get RGB data for pixels from bitmap?
For every pixels, and write them into txt file
Not using GetPixels, only from Bitmap
|
|
|
|
|
If you mean a Bitmap (GDI+), then use GetData. The next issue of WDJ will hopefully have an article covering all this.
If you mean CBitmap, you need to create a DIBSection. If you have a bitmap already, then copy it into a DIBSection and access the data that way. If you're creating it, create a DIBSection. This site has several DIBSection wrappers, from memory. It certainly has one.

I have LPBITMAPINFOHEADER structure (it's a frame from avi file),
i can save it as bmp file, but i need array of pixels only,
like this:
12 11 34 ....
32 11 22 ....
.............
22 44 44 ....
and save it as txt file
|
|
|
|

If it's a BITMAPINFOHEADER and not a BITMAPINFO, then you don't have a bitmap at all, just a descriptor of what dimensions one should be. Try casting to BITMAPINFO and accessing bmiColors. The first member of BITMAPINFO is BITMAPINFOHEADER, so a cast from BI to BIH will work fine where a BIH is needed.

I tryed, but i don't know how to get every pixels at all (array of RGB)!
If you know how it works, please help me.
I really need it.
Thanks

It's an array of RGBQUAD, so it's a pointer that contains the values for each pixel as red/green/blue/reserved. Generally Windows bitmaps go bottom to top, left to right, I presume this is the case here.
So to get the values you could do something like:
BITMAPINFO * pBMI = (BITMAPINFO*)MyBitmapInfoHeader;
RGBQUAD * pQuad = pBMI->bmiColors;
for (int x = 0; x < pBMI->bmiHeader.biWidth)
for (int y=0; y < pBMIHeader.biHeight)
{
unsigned char Red = *pQuad;
++pQuad;
unsigned char Green = *pQuad;
++pQuad;
unsigned char Blue = *pQuad;
++pQuad;
++pQuad;
}
That is untested, but you get the idea.

What seems to be the problem? You are using BSTR, right?
|
|

|

I wasnt using BSTR - I found several "ways to do it" on the net, but I wasnt sure so I didnt want to jump in before I asked.. but I'm using BSTR now and it works - thx!

Hi all,
If I have a global group which has another global
group inside it.For example I have a global group named test and another
global group test1 which is a member of test. I have a user say "A"
which is a member of test1. Now Is there a way I can programmatically find
out whether "A" is a member of test or not. If I try to use the
function "NetUserGetGroups" for "A" it does not return test as one
of the groups to which "A" belongs .
Thanks in advance

A co-worker sent me the following code so that I could read and write file properties to the file. I pretty much used the open file, open stream in one part to read the properties. I use the open file, open stream to write the properties elsewhere. I don't know why it's not opening the file for writing, and I was hoping someone knew why. At first, I also had Windows Explorer running because I constantly had to retype new comments and authors for test. That's not what's happening. I don't think IPropertySetStorage has a close, so I'm not sure what to do.
int main(int argc, char* argv[])
{
CoInitialize(NULL);
try
{
USES_CONVERSION;
CComPtr<ipropertysetstorage> l_spIPropertySetStorage;
HRESULT hr;
hr = StgOpenStorageEx( L"e:/test/test.spw", STGM_READWRITE | STGM_SHARE_EXCLUSIVE,
STGFMT_ANY, NULL, NULL, NULL, IID_IPropertySetStorage, (void**)&l_spIPropertySetStorage );
if (FAILED(hr)) throw _T("Failed in StgOpenStorageEx");
CComPtr<ipropertystorage> l_spIPropertyStorage;
hr = l_spIPropertySetStorage->Open(FMTID_SummaryInformation,
STGM_READWRITE | STGM_SHARE_EXCLUSIVE, &l_spIPropertyStorage);
if (FAILED(hr)) throw _T("Failed in l_spIPropertySetStorage->Open");
PROPSPEC l_aPropertySpec[2];
l_aPropertySpec[0].ulKind = PRSPEC_PROPID;
l_aPropertySpec[0].propid = PIDSI_AUTHOR;
l_aPropertySpec[1].ulKind = PRSPEC_PROPID;
l_aPropertySpec[1].propid = PIDSI_COMMENTS;
PROPVARIANT l_aResults[2];
hr = l_spIPropertyStorage->ReadMultiple( 2, l_aPropertySpec, l_aResults );
if (FAILED(hr)) throw _T("Failed to l_spIPropertyStorage->ReadMultiple");
if (S_FALSE == hr) throw _T("Properties not found");
if ( l_aResults[0].vt != VT_LPSTR ) throw _T("vt is not VT_LPSTR");
if ( l_aResults[1].vt != VT_LPSTR ) throw _T("vt is not VT_LPSTR");
CComBSTR l_bstrAuthor = l_aResults[0].pszVal;
CComBSTR l_bstrComment = l_aResults[1].pszVal;
MessageBox(NULL, OLE2T(l_bstrAuthor), _T("Author"), MB_OK);
MessageBox(NULL, OLE2T(l_bstrComment), _T("Comment"), MB_OK);
CComBSTR l_bstrNewAuthor = L"Brad";
CComBSTR l_bstrNewComment = L"Here's my new comments";
// set new values
PROPVARIANT l_aNewValues[2];
l_aNewValues[0].vt = VT_LPSTR;
l_aNewValues[0].pszVal = OLE2A(l_bstrNewAuthor);
l_aNewValues[1].vt = VT_LPSTR;
l_aNewValues[1].pszVal = OLE2A(l_bstrNewComment);
hr = l_spIPropertyStorage->WriteMultiple( 2, l_aPropertySpec, l_aNewValues, NULL );
if (FAILED(hr)) throw _T("Failed in l_spIPropertyStorage->WriteMultiple");
hr = FreePropVariantArray(2, l_aResults);
if (FAILED(hr)) throw _T("Failed in FreePropVariantArray");

{

Is there a easy way to convert a "int" to CString "Days:Hours:Minutes:Seconds";
.. Knowing that the "int" is a total of seconds..
Thanks,
Rob

time_t defined in <time.h> is an integral type (usually long int) intended to store the number of seconds elapsed since 00:00, Jan 1, 1970 UTC. The function gmtime() accepts such a time_t value and returns a pointer to a tm struct whith that instant in time expressed as year, month, day and so forth. Assumming the number of seconds elapsed refer to that very moment in time (1970), your code should go along this line:
int iTime;
CString strTime;
tm * ptm=gmtime(&((time_t)iTime));
strTime.Format("%d:%d:%d:%d",ptm->tm_yday,ptm->tm_hour,
ptm->tm_min,ptm->tm_sec);The extension of this to the cases when the time elapsed is more than a year and when your zero time is not what gmtime() assumes I left you as an exercise

Good day,
How would I go about determining whether a checkbox is checked/unchecked on a webpage inside my HTMLView? This is a custom webpage that I have the source and know all the info about it. The view doesn't allow users to cruise the net, its like the Outlook Express startup page. Any leads/info/help is greatly appreciated.

This is a nice article and I thank you for your response. The problem is that this is for CE and is a CCtrlView which uses DISPLAYCLASS (the name of the html control class under CE). Is it still possible with this as the base class or do I need to redo this class? Thank you once again for your response.

I will give that a shot. I will respond a bit later with the results.
Thank you very much.

I tried to get an IHTMLWindow2 interface using your suggestion, but was unsuccessful. I need to use the function HRESULT IHTMLWindow2::get_history(IOmHistory **p), but I have yet to find a way to reach that interface.
Perhaps I am not looking at the right place or that interface is not reachable. I am a little new to this area of VC++, please excuse me if the answer might be apparent.
