How do I write
<br />
ActiveChart.SeriesCollection(1).XValues = "={""Date <br />
08102003"","" Date 08102003""}"<br />
in MFC?
Here is my code for the chartwiz..
<br />
this->m_xlChart->ChartWizard(var,
COleVariant((short)3),
COleVariant((short)2),
COleVariant((short)2),
COleVariant((short)0),
COleVariant((short)1),
COleVariant((short)TRUE),
COleVariant("MyChart"),
COleVariant("Date"),
COleVariant("UNITS"),
covOptional<br />
);<br />
Basically I want to change Category (X) axis labels to something other then 1, 2, 3... etc.
Sincerely,
Mardigin

Disregard, I just solved this problem. Silly me.
Here is the solution if anyone is interested.
<br />
<br />
xlSeries = this->m_xlChart->SeriesCollection(COleVariant((short)1));<br />
<br />
VARIANT vResult;
VARTYPE vType;<br />
<br />
DISPID dispID;
unsigned short *ucPtr;
ucPtr = L"XValues";<br />
HRESULT hr = xlSeries.m_lpDispatch->GetIDsOfNames(<br />
IID_NULL, &ucPtr, 1, ACCESS_PROPERTY_GUID, &dispID<br />
);<br />
<br />
CString lpszNewValue= "={""Label1"",""Label2""}";<br />
<br />
if(hr == S_OK)<br />
{<br />
xlSeries.SetXValues(COleVariant(lpszNewValue));<br />
}<br />
Sincerely,
Mardigin

In C++, to insert a """ character you have to use "\"", not """" like in VB.

Try something like...
(This comes from a wrapper around the NetUserAdd function)
Declare your function / routine like this...
extern "C" int __declspec(dllexport) AddUserAccount( LPSTR domain, const char *acct, const char *pass, const char * comment)

Hi ,Judd
Thanks a lot .What is the "__stdcall" different from the "__declspec" .I am trying ...I think my enlish is very bad .are you American?
Good luck
Hellin

|

|

No problem,
"__stdcall" and "__declspec" are calling conventions, and effect how argumetns are passed (e.g. by ref or by val) and also how they are 'decorated' when externalised.
You might find some use reading here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_core_adjusting_naming_conventions.asp
(I'm actually English and since you are talking about __stdcall are you doing mixed language with FORTRAN by any chance?)

Hi, buddy
That all right .a Func of DLLs for PB must be de Declared like this "__stdcall" .Others don't work .do you understand me ? My craft brother.
Thank you very much .

Ok since VS2003 i have a new References folder in every of my (Native-) C++ solutions.
Now frankly i have no idea what this is for. I'm familar with references in the managed envirement and for web services, however two oddities :
1) If i have a multi project solution it offeres me to add one project as reference of another. Nice but what does that do.
2) If i select browse it lets be browse for "Component files". What the hack is a component file.
I dreamed for a long time for some sort of component system in c++ where i can pack my different mini projects in a zip file including all source and a make file like xml and than just drag drop them on the project i'm working on and it will be included in the build process. Is this new reference folder anything which comes close to my wish ?

I may be starting an application before long which will receive digital audio streams, and then run these streams through an algorithm before passing the streams back out of the application (sort of a filter). I've not really processed digital audio streams before, and I'd like a reference to begin with. I am best with C++, but I'm not against using some other language like BASIC if it is necessary, but I'd prefer to stick with what I am the most comfortable with. If anybody has experience with receiving and processing digital audio streams, could you please guide me with a book or two that would be a good starting point to learn from? I'd greatly appreciate it. Thank you!!!

If you are doing this on a Win32 platform. You should probably look at DirectX DirectShow. If you download the SDK there are a bunch of Audio Filter Examples. DirectX has a comprehensive framework for encoding, decoding and transcoding media streams.

I am trying to write a Win32 WinSock app and nothing is working! winsock2.h by itself gives me 70 errors (and i linked the lib file). winsock 1 refuses to let me use SOCKADDR_IN, so what is going on?

Hi,
In my program I keep getting this error whenever I move my dialog or, OnOK and OnCancel.
It says:
Debug Assertion Failed.
File: winctrl2.cpp
Line: 1202
In winctrl2.cpp I have gone to the line 1202:
BOOL CImageList::Attach(HIMAGELIST hImageList)
{
1202: ASSERT(m_hImageList == NULL); // only attach once, detach on destroy
ASSERT(FromHandlePermanent(hImageList) == NULL);
if (hImageList == NULL)
return FALSE;
CHandleMap* pMap = afxMapHIMAGELIST(TRUE);
ASSERT(pMap != NULL);
pMap->SetPermanent(m_hImageList = hImageList, this);
return TRUE;
}
It has something to do with the ImgaeList that I added to the Tree control in my program.
I added the tree control like this:
m_nTree.SetImageList(&m_ImageList, TVSIL_NORMAL);
In ONOK and OnCancel I even added following line:
m_ImageList.Detach();
Still I keep getting the assertion error.
Can anybody help please?
Thanks,
Binayak

You attach the Imagelist to the tree control more than once.
if you attach a imagelist to the tree ,the m_HImageList will not be NULL, if you attach again ,the ASSERT(m_HImageList==NULL) will break, so you should init the tree imagelist in the OnInitDialog() and don't init again.
I think is it.
|
|
|
|
|
Hi,
I'm sure I attached to the tree control only once and that is in the onInitDialog().
Still this is not working. Any other suggestions?
Thanks,
Binayak

You could try to protect the adding of the image list with a bool variable:
In your dialog, add a bool variable firstTime, set to true in constructor.
Modify the part where you add the imagelist to look like this:
if (firstTime)
{
m_Tree.SetImageList(&m_TreeImageList, TVSIL_NORMAL);
firstTime = false;
}Additionally, I think you can drop the calls to detach(), as this will be done automagically when the tree goes away.
Who is 'General Failure'? And why is he reading my harddisk?!?

Hi,
Thanks for your reply.
I tried doing what you said.
But, in this case also if I try to move my dialog box, I keep getting the same error (debug assertions failed)
I'm including call stack and part of code with this:
Call stack: shows line 140 which is shown in the code.

Hmm.
Seems like your imagelist creation is failing?
Please check the return value of m_ImageList.Create(..).
Nonzero is signaling an error.
Who is 'General Failure'? And why is he reading my harddisk?!?

|

I have checked the return value of Create(...)
It's true.
any other suggestions?

Hello,
Sorry for my c++ stupid question but i really forgot to get the size of an array in a func 
typedef struct<br />
{<br />
char *item;<br />
int top;<br />
int bottom;<br />
} Item;<br />
<br />
<br />
void Draw( Item* item )<br />
{<br />
<br />
int nSize = sizeof(*item) / sizeof(Item);<br />
<br />
}<br />
<br />
main()<br />
{<br />
Item array[] = { ... };<br />
Draw( array );<br />
}
Any idea ?
Best Regards,
Hadi

You can't do that. The array is actually passed into the function as a pointer, not as an array. This means that sizeof(item) will always be 4. Instead you should either pass through the size of the array as a separate parameter, or even better, use an STL container such as a vector, which includes its size within the container itself.
