We've developed a component for sending and reading large messages to msmq queues for communication with Biztalk as implemented as described in this MSDN-article: http://msdn.microsoft.com/en-us/library/aa560386.aspx
Simply explained, you use the PROPID_M_EXTENSION field to describe the parts of the messages using the following content:
GUID defining that it is a multi-part message (16b) GUID for the message (16b) Total size of the entire message (4b) Current part number (2b) Number of message parts (2b) This works perfectly with Biztalk 2006, however with newer editions (2010/2013) it does not work at all.
We've sent large messages out from Biztalk 2013 to a queue and analyzed the field and it seems that the content of PROPID_M_EXTENSION is:
GUID defining that it is a multi-part message (16b) GUID for the message (16b) Part number (2b) Empty data (2b) 1 if it is the last part, otherwise 0 (1b) 3 unknown bytes The problem is the last three bytes, that we can't figure out the purpose of and how to calculate.
The values differs depending on the message content and size. And it feels like some sort of check sum, but we need to be able to set this manually.
Any ideas? There is very little information about this around the web?
The existing mqlarge-dll is in native code and can only be decompiled to assembler, which (for me at least) is hard to debug.
A way around it would be to include a reference to mqlarge in our project and use the existing assembly, but we would rather have our own code and not be dependent on a dll. And it bugs me not to know how it works as well

Hey there,
I have a MFC app that uses CDHtmlDialog class. It supports most of the HTML tags, but not the CANVAS tag. If am right, IE 9+ only have support for Canvas tag.
Which version of IE is used in CDHtmlDialog class?
Is there a way of using Canvas tag in CDHtmlDialog class?
If not the CDHtmlDialog class, is there any other web browser control in MFC that supports Canvas tag?
The reason why i am using CDHtmlDialog class, is to create a rich GUI using HTML/CSS/JavaScript that will be updated dynamically from the back end C++ code.
Thanks in advance.

The version of IE that is used by CDHtmlDialog is dependent on the OS you use. You can use webkit whick is better than IE. I prefer you to use cef whick is based on Chrome. And Chrome is based on webkit.

As mentioned in the previous answer, the version of IE used depends on your OS and what version of IE you have installed, but that does not mean it defaults to using IE10 compatibility even if you have IE10 installed.
You might have to take to the registry to get the browser control to behave correctly. Check out this on SO[^], this on MSDN[^] and check your settings by connecting to this[^]
Make sure your HTML file has <!DOCTYPE html> at the beginning and you might have to have <meta http-equiv="X-UA-Compatible" content="IE=9"> in your document as well.

Can anyone direct me to an article or book that covers Snippets. It seem like Microsoft had a good idea, but no one wrote down the instructions............Again!
I understand the concept, but not the details. I would also like to know if the snippet is copied and pasted into the IDE or are the snippets linked to as a library at build time?
Thanks,
Barry

Sorry but what does this have to do with C++?

Because its part of the VC 12 IDE package, which millions use to write C++ with!
I am looking for someone with more experience than I. Isn't that part of the purpose of Code Project?

I'm looking forward for buying a mac, I will start game development but what is the best mac for programming in C++?
|
|
|
|
|

Best mac for visual C++? ...none really. Visual C++ is pretty much the name of the C++ compiler for Windows, so your question is a bit of a contradiction.

Hello community,
i call/open a help-file from my program, this works fine,
only one thing i can't resolve:
on the help file, if i select a next tab(on the left side), for example tab to search in help content, and close file.
Any next start of that file is the last selected tab from previous call. And that is my problem: how to call the help file with selected first tab item, this is how i call a help file:
<br />
HWND hwndHelp = ::HtmlHelpW(m_hWnd, csPathToHelpFile, HH_DISPLAY_TOPIC, dwTopic);<br />
Helpfile is opened, the right topic is shown, but the tab who is selected is the last one of the previous call, how to set the selected Tab to first index?
I found this in "HtmlHelp.h": HH_DISPLAY_CONTENT, is this a key to show first tab with topics?
Thanks in advance

Hi,
The code below fails to get any input pins for the filter "Mp3 Decoder DMO".
The class ID for the specific filter is {94297043-BD82-4DFD-B0DE-8177739C6D20} . Specifically, it fails at the very first while condition. I get S_FALSE which means "Did not retrieve as many pins as requested."
Does it play any role that this specific filter is DMO (Direct Media Object) filter ? If this is the case, is there nay other way to get the input pins ?
In my graphedit it connects and works just fine , but under my code it fails. Any recommendations ?
IPin* Graph::GetPin(IBaseFilter *pFilter, PIN_DIRECTION PinDir, UCHAR PinCounter) {
BOOL bFound = FALSE;
IEnumPins *pEnum;
IPin *pPin;
HRESULT hr =S_OK;
UCHAR localPinCounter = 0;
hr = pFilter->EnumPins(&pEnum);
if (SUCCEEDED(hr)) {
while(pEnum->Next(1, &pPin, 0) == S_OK) {
PIN_DIRECTION PinDirThis;
pPin->QueryDirection(&PinDirThis);
if (bFound = ( (PinDir == PinDirThis) && (PinCounter == localPinCounter) ) )
break;
pPin->Release();
localPinCounter++;
}
pEnum->Release();
} else {
return 0;
}
Regards,

hi
hi can u please help me to convert string in Unicode bytes,
I do this like this:
CString Hex(long val)
{
CString Buf=_T("");
Buf.Format(_T("%X"),val);
return Buf;
}
int Asc(const CString &cs)
{
unsigned char ch= cs[0];
return ch;
}
int AscW(const CString &cs)
{
CString g=_T("");
int ch = cs[0];
g.Format(_T("%d"),ch);
return _ttoi(g);
}
CString EncodeUserData_16_bit(CString strUserData)
{
CString EncodeUserData_16_bit;
int I=0;
CString hex_string=_T("");
for( I = 0; I<strUserData.GetLength();I++)
{
hex_string=_T("");
CString c=strUserData.Mid(I + 1-1, 1);
int ch=Asc(c);
CString g=_T("");
g.Format(_T("%d"),ch);
ch=AscW(c);
g.Format(_T("%d"),ch);
hex_string=Hex(AscW(c));
if(hex_string.GetLength()<4)
{
hex_string=PadZero(hex_string,4);
}
EncodeUserData_16_bit=EncodeUserData_16_bit+hex_string;
}
return EncodeUserData_16_bit;
}
its convert the string in Unicode bytes only one problem is that
if I convert "hello" to Unicode its return "00680065006C006C006F" but this result mismatch at the end of process.
if in place of "00680065006C006C006F" the value is "680065006c006c006f00" the process successfully finish.
if u please guide me anyhow of help me to solve this, its so grateful to u.
thanks in advance.

Try something like ...
CString EncodeUserData_16_bit(CString strUserData)
{
CString strEncoded;
for(int i = 0; i < strUserData.GetLength(); ++i)
{
CString unext;
unsigned int chnext = strUserData[i];
unext.Format(_T("%.4X"), chnext);
strEncoded += unext;
}
return strEncoded;
}

Well it works fine for me. Maybe you should explain why you think the result is not correct.

Does anybody know how to program a pic micro in C to detect gradient. I have set up ADC pins and each LDR is detecting light. Just need to set that a specific gradient of light detected by LDR will switch a light on.
|
|
|
|

Quote: gradient
Do you mean "range of frequencies" (or "range of wavelengths")?
Programming the PIC is relatively simple, I believe. You have first to:
- Be sure your light detector is sensitive to such frequency range.
- Filter in the light of such frequency range.
Once such conditions are satisfied you'll get a high value on the ADC measure when the 'gradient of light' is detected.
Veni, vidi, vici.
