find a graphics library that supports reading ICO to RGBA-32, and that can write PNG-32

How to programmatically perform actions online?

If you need to do it non-problematically, I've found that IcoFX is a great, free tool.

Does there exist a sample project which will perform actions online? For example, lets say there is a webpage with a login and passcode. How could I programmatically have the software enter that data and hit Enter? I get to another page that has Next. How can I programmatically click that Next button.

Eventually what I want to do is programmatically upload a file.

If there exists any type of sample project that anyone can point me to, that would be great.

Sincerely,
Danielle Brina (an overworked graduate student)

Something like that might require a high level of machine intelligence, unless you are creating it to interact with only a small set of pre-defined pages.

Instead of interacting with the web page like that, why not think about interacting with the web server as if you are the browser?

For instance, have your program connect to the web server, and issue its own POST request.

I want it to interact with a small set of pre-defined pages. And I
know what those pages are.

In fact, all the program has to do is get past a login page, click
Next, Next and then upload a file.

Is there any sample project you know of that would do something like
this? For example, if I could programatically log into yahoo, maybe
that would be the first step. If I could do that, I might be able
to do the same for this project.

I don't know of anything that already exists that you could coopt for your purposes.

However, people on this website can help you a great deal if you are very specific about what it is that you don't know how to do.

What is your current level of competency with writing Windows programs in C++?

Doing what you require is a multistep process; which step is giving you trouble:

1. Downloading the page
2. Parsing the HTML to find the link(s) you are looking for
3. Performing a virtual click on the link

How to convert non ATl project to ATL compatible

Hello,

I am working in Visual Studio 2008. I currently have a project that was created years ago that deals with COM components. Now, however, I need to add new functionality to this old project. The new functionality would be easiest if we used ATL. However, the problem is that the old project is not an ATL project.

So, my question is: Is there any (easy) way to convert my old project to an ATL compatible project?

Thanks in advance,
Nick

P.S. If my description is too vague or there are any questions just let me know. Thanks.

May be you can check if the following MSDN link helps (assuming the existing project is in MFC): http://msdn.microsoft.com/en-us/library/f8bk32xd(VS.80).aspx[^]

hi,
i have a tree ctrl with Number of items say 10 items under one root Node,
at the end of each child item i need to add an image .

How is this Possible ?

Thanks,

hi,
My objective is end of each child item i need to add a image.

Example :

Root
|
Child 1 text [image]
Child 2 text [image]
Child 3 text [image]
Child 4 text [image]

above [image] -> image of size 12*12

You need to owner draw the items. (search for NM_CUSTOMDRAW on msdn )

but if you want to add an image at the "beginning" of each item, you can simply use CTreeCtrl::SetItemImage.

hi,
Thanks for ur kind reply,

Do we have any sample program for that..?

it will be more helpful to complete.

NM_CUstomDraw i have gone through this, but hope we have text property on that.

have not seen the image property on that.

Dear ...,

I am hamid majidi, graduate master student of engineering. I have a question about c++ and c# , that really confused me. I work in digital image processing, computer vision and neural network with MATLAB. But, I want to develop my programming skill, therefore,I would like to choose between C# and C++. I would like to know, wheter c# or c++ is suited to Computer vision, Image processing and neural networks?
Roll eyes | :rolleyes:

best regards,
majidi

They both are good enough for all of that.

For digital image processing algorithms peformance is critically important so for neaural networks to.
C++ gives the programmers better control to apps low level feutures and allows to to manage the memory of your program on your own and allows to to include assembly statements to improve the performance of your algorithms, but it's more difficult to learn and it will take you longer time and much more effords to learn rather than C#.C# simplifies the development process and make it easier, cheaper and faster.It doesn't allow working on low level and manual memory management, but you are able to learn it really fast.So if you are science oriented and you want to gather the best performance of the algorithms you are developing C/C++ should be preferred.

In general C# is easier.
But every time I need complex image processing me switches to C++ or C, because to operate directly
with memory in C# is that kind of cruel and slow ... or you can use unsafe code in C# (but I don't like it Laugh | :laugh:

I say C++ because one of the most critical skills programmers need to learn is HOW computers and algorithms work. These skills aren't language specific, but C# tends to hide some of this stuff and all too often lets you get accustomed to some really bad habits.

Moreover, well written optimized C++ will run circles around C#. (And knowing the above, you will also understand why well written C# sometimes outperforms C++ on first go and will help you make C++ the speed demon it can be.)
