Hi All,
I am working on an ActiveX based project.
I am using AtlAxCreateDialog method to create a dialog whose resources have been specified in a RC file. The dialogue gets created perfectly fine but i have not been able to handle its events like OnSize, OnClose etc
It has taken me a while to solve this problem but didn't succeed. Kindly, help me.

Calling AtlAxCreateDialog directly is unusual: normally it’s called for you in the implementation of the CAxDialogImpl::Create method.

I have created a toolbar for IE and added a an edit control to it, but I couldn't add a menu control beside to the edit control. Can anybody help me, please. Thanks a lot.

first, create a menu in your resource file.
second, put a button to the toolbar that will open the menu up with a style BTNS_WHOLEDROPDOWN
third, get a command handler handle the button's command ( WM_COMMAND message )
and lastly, write a method that creates the menu and tracks it. something like:
HMENU hM = ::LoadMenu(ATL::_AtlBaseModule.GetResourceInstance(), MAKEINTRESOURCE(ID_MENU);
HMENU hMPopUp = ::GetSubMenu(hM,0);
::TrackPopupMenu(hMPopUp,TPM_TOPALIGN,pointX,pointY,0,m_hWnd,NULL);
that's the way i did it, i think you can handle the rest with the holy MSDN

What does this have to do with ATL/WTL? You are in the wrong forum...

Can you more explain and with which language?

Hello,
Read the article on MSDN: “How to Pass Arrays between Visual Basic and C”. http://support.microsoft.com/kb/207931
Some more links:

Hi,
I'm kind of new to ATL programming, but I have been working with it quite extensively over the past few months. I've been writing code for a toolbar for IE and unfortunately I got stuck on one part and have no idea how to solve it. Google and MSDN are not being very helpful, but I think that the main reason I'm having trouble is because I do not understand the concepts fully.
Anyway, here is the problem: I want to be able to detect the WM_INPUTLANGCHANGE message within my toolbar. I tried adding it to the MESSAGE_HANDLER to one of the windows, but it seems to be ineffective.
Any information you can give me to point me in the right direction would be great!
You can assume that the code I have is the same as in this tutorial:
http://www.codeproject.com/atl/ietoolbartutorial.asp
Thank you in advance,
Andrej

What are the conditions in which a CAB fiel refuses to overwrite a previous downloaded instance in IE.
Is it the time-stamp of the CAB file;or do CAB files need to mention a versioning too.
We are downloading a CAB file from a jsp with a OBJECT tag.
After we modify the CAB file and repackage it ,we find that CAB file does not download the new instance again,as the old instance is already downloaded into the client box.
We are creatign the CAB file with visual studio.
If versionign is the answer to overwriting downloaded CAB files from IE - how do we version CAB files in 'VS Deployment type of projects'
|

You need to increase the version attribute in the web page. The modified date of the CAB itself is irrelevant. Think about it, the original CAB is discarded after it's installed, and even if it were kept around, IE would have to download the entire CAB file every time you visited the page just to check the date.

I am working in the compact framework.
I have an ATL object that needs to draw on a bitmap. I need to pass the bitmap to a C# program and display it. We have tried creating the bitmap in C# with GDI methods then used the APIs for CompatibleDCs, selectobject, getHdc, etc and passed the DC to the ATL object. On returning it from the ATL object I get ExceptionHandling errors relating to memory when I try to get a bitmap I can use in managed code. We have been able to pass the DeviceContext and draw directly on it but I want to retrieve a bitmap that I can cache as a member variable in my class.
Has anyone successfully passed bitmaps back and forth between managed and unmanaged code?

Hi Mike thanks for responding. Would you describe the method you used.
I tried creating a bitmap from the device context of the screen, passing the Device Context and hBitmmap to unmanaged code, drawing on the bitmap in unmanaged code and passing back to managed code. But when I try to draw in managed code using GDI I get a memory exception.

|
|
I passed only HBITMAP

how are you drawing to the bitmap in unmanaged code? Don't you need a Device Context?

hi c++ guru.
i need your help... i'm new in hardcore c++ and currently working on a c++ container namely the priority_queue. i don't have problem using the priority_queue itself but i have this additional requirement to also consider the age of the items in the queue.
my current implementation only deals with the priority of the items in the queue by overloading the "<" operator. i don't know yet what to do when considering the age of the items in the priority_queue.
any help is greatly appreciated...
PS: sample code would be a great help...

You can make another priority_queue that stores the priority as the time you added the item to the priority_queue. Store a pointer to the same item in both queues? Of course, this is kind of an ugly way of doing it.
I recently made a priority_queue that stores pointers to Event objects. Each Event stores the time the event should run, as well as other important information it needs when it runs. I overloaded operator() and operator< to handle comparing the Event->_nTime to another Event->_nTime.
Basically I pop the next Event to run (smallest time) and run it when it's time has come.
Unfortunately, i don't think that approach will help you. Sounds to me like you want to extend the priority_queue itself to track age of items as well as priorities, which is pretty difficult. Easiest method might be to use two of them like I mentioned above.
Maybe some more details on what your program does?
