Hi,All

I am developing a GDI graphics ActiveX Control with atl, it has a picture property.How can i set the picture value when i create the bitmap every time in the function OnDraw, the following is the my snippet code:

HRESULT OnDraw(ATL_DRAWINFO& di)
{
Graphics graphics(di.hdcDraw);
RECT& rc = *(RECT*)di.prcBounds;
Height = rc.bottom-rc.top;
Width = rc.right-rc.left;

Bitmap bmp(Width,Height);
Graphics * pMemoryGraphics=Graphics::FromImage(&bmp);
MyImage * img= new MyImage();
img->DrawGraphics(pMemoryGraphics); // draw the graphics
graphics.DrawImage(&bmp,rc.left,rc.top);
// here i created the bitmap "bmp", how to pass it to m_mPicture?
// CComPtr<ipicturedisp> m_pPicture;

I am very appreicated if someone can help.

Virtual memory Allocation

ckkmohan3-May-05 2:55

I have problem with ATL COM exe

First I build the exe in Win32UnicodeReleaseMinDependancy settings , seems to be allocating 13324 k virtual memory (VM) at startup and then it allocates 1.8 GB which grows up to 1.9 GB of VM
but at the same time exe build in Win32UnicodeDebug settings allocates only 1160 k at startup and allocates 1672k VM , which increases slowly

Previous version of the same exe is working properly (allocating less amount of virtual memory ) and I compared all the project setting of new exe with older one both are same

Can any one suggest me why exe build in
Win32UnicodeReleaseMinDependancy allocates 1.9 Gb of virtual memory ???

   Programming Error? Doing things like abusing dynamically allocated memory (misusing string objects, etc.) will do things like that.

   Also, double check for dangling (un-released) interface pointers. For example, I once had an issue with an OleDB object that was getting binary data from a database table. I was not releasing the IStream interface pointer I was getting back, and after about 20-50 records, the memory allocations started to skyrocket!

   Behaved completely differently under DEBUG than RELEASE.

   Peace!

Urgent! How to instanciate an OCX ?

I've made an OCX control. It works fine OK.

I want to instanciate that OCX when a .fbx file is dropped from file explorer on an Office application ... How can I do that?

Ex: In a PowerPoint slide I want to drop from file explorer myfile.fbx and this will instanciate
my FbxViewer.ocx in the PP slide and myfile.fbx will be loaded into my OCX control.

Thanks

COM and structures

Dear friends,

I developed an ActiveX control using ATL and Visual C++ 7.0. One function exposed by the control takes too many arguments, around 15 in number. As scuh i want to pass structure instead of too many arguments.

But ATL is not giving me any option to add my structure as an argument ot the exposed function ? Please tell me what is the solution of this problem ?

Also i want to use my control by VB/JAvaScript etc. So what is the better way to solve this problem

Brilliant observation! A thousand pardons.

VB Script and JavaScript (the scripts mentioned by the original poster as being pertinant) do not support structures.

Hi Imtiaz ,
Refer to this article from MS-MSDN.

This article is talking about something, which you are looking for.

As far as VB is concern, it must work !
I dont have much idea about scripting languages Frown | :(

Hi,
can I get help on how to block and realse the ports for Win 98 OS. From msdn i found that ipseccmd is the utility that could be used for Windows XP and Windows2000 to block/release ports. Similraly, is there any utility available for Windows 98? Or is there any other method by which I can block/relase ports for Windows 98(i.e, any registry enry that helps in blocking ports)???????
Thnx in advance

Outlook CreateDispatch error - "No such interface supported"

Nickmatic28-Apr-05 15:39

28-Apr-05 15:39

Hello.... have solid, reliable code in C++ that automates Outlook. It has been around for a few years and 99.9% of my users report no problem.

However, occasionally a user reports that they get an error when CreateDispatch() is called. The code is 0x80004002 - No such interface supported.

Sometimes a repair or re-install of the Outlook installation fixes it, most times it does not, and those customers are just out of luck.

Any ideas what might be causing this problem? Of course I can't seem to duplicate it here....

Thanks!

Hello,

I'm receiving this very peculiar warning, after which my application crashes.

Warning: constructing COleException, scode = severity: SEVERITY_ERROR, facility: FACILITY_WIN32 ($800706BE).

I'm using Windows XP with SP2. The same application works fine on Windows 2000 SP4.

Googling didn't help at all... Hence posting this query here, just if anyone is aware of or has encountered this error and has some solution for the same.

Thanks,

I think the 800706BE HRESULT code corresponds to
RPC_S_CALL_FAILED

Its defined in winerror.h

Search for this on google.. you might get something. I'll try and find some reason why its not working.

Hi All,
Does anyone know of a MFC function equilivant to the OleRequestPendingTimeout function used in VB and V FoxPro? This is to prevent the "This action cannot be completed beause the 'file.doc -Micorsoft Word' program is not responding. Choose 'Switch To' and correct the problem" Message from appearing!

Thanks
