If you are wanting to tie it to browser activity, then I suspect a Browser Helper Object (BHO) is what you are after.

Thanks do you have ant pointers where I can check and if there are any exemple?

I have a few nested splitters on my main screen and two of the panes use forms that are exactly the same in look and functionality except for a couple of strings. If there was a way I could send in some value to determine which stored procedure it should use to fill the list control, everything would be great and I could use an instance of the same class for both panes. But I create the formviews using RUNTIME_CLASS when creating the splitters.
While writing this post I've just thought about I could make the class I want to use a parent class, make two derived classes, each one calling the parent's constructor with the string or enum values I want. Something like this:
class CLeftFormView : public CMyFormView
{
};
class CRightFormView : public CMyFormView
{
};
This seems like it would work, but I wonder is there a better method for what I'm trying to do. Any suggestions are appreciated.
Thanks

Actually, that seems like a pretty reasonable approach to me. I'd definitely give it a go.

I'm reading a bunch of raw numerical data (floats representing verticies) from disk in one endian format, and need to convert it to another (flip the bytes around).
Currently I am reading the numbers one by one and bit-shifting them to the correct format, then placing them into their respective places in an array of verticies (float[3]'s).
I am trying to speed up this whole operation, and may be able to do so with a better method/algorithm. The following also may help:
- Each float is 4 bytes and needs a pure reversal of bytes - not bits (bytes 1234 become 4321)
- the floats are contiguous on disk
- I know ahead of time how many floats I will be loading into a given array
- The array will be pre-allocated to hold the right number of verticies
- I must keep (or end up with) the array two-dimensional (array of float[3]'s) for later OpenGL usage
not sure if reading them all in at once, and applying a macro-bit-shift would be faster?
Thanks for any help

Yes. Reading them in one at a time increases disk access (which is expensive). Reading them in as a block decreases the number of reads required to get your data.
Something along the lines of the following should work:
float endian_shift(const float& f)
{
float ret = 0.0;
ret |= (f << 24);
ret |= ((f >> 8) << 24) >> 8;
ret |= ((f >> 16) << 24) >> 16;
ret |= (f >> 24);
return ret;
}
ifstream fin;
fin.open("myfile.dat", ios::binary);
vector<float> myData(SIZE);
copy(istream_iterator<float>(fin), istream_iterator<float>(), back_inserter(myData));
fin.close();
transform(myData.begin(), myData.end(), myData.begin(), endian_shift);

Thanks for the reply,
Just tossing a few other thoughts around...
Given the following:
- vertex is of type float[3]
- verticies is an array of SIZE vertex (verticies = new vertex[SIZE];)
- vertsfromfile is an array of (SIZE*3) floats
are the floats in "verticies" aligned one after the other in this fashion:
verticies[0][0]verticies[0][1]verticies[0][2]verticies[1][0]verticies[1][1]...and so on to allow for something like memcpy(verticies,vertsfromfile,(sizeof(vertex)*SIZE)) ?
or is this just crazy talk?
Thanks

If the file is written out such that each vertex is written as float1float2float3, then writing out a series of vertices would just mean you would have vertex1vertex2vertex3... where each vertex matched the pervious pattern. Thus, you could read them in in such a fashion (though, I would still stick with using the copy algorithm).

Hi!
Can anyone tell me how to enumerate the USB Hubs connected to my PC?
In theory (i think) it should work like this:
hDevInfo = SetupDiGetClassDevs(GUID_DEVINTERFACE_USB_HUB, NULL, NULL, DIGCF_DEVICEINTERFACE | DIGCF_PRESENT);
...and give me a list of the hubs. Using GUID_DEVINTERFACE_DISK as GUID works perfect for harddisks but when i try to use GUIDs from the usbiodef.h nothing is found.
Can i use my VS.NET 2002 for this or does it only work with the c Compiler from the DDK?

u can search in registrey . the ddk has a sample in it . name of that sample is usbview. just check it out.
If u can Dream... U can do it

Hello there. I need help with a simple MFC program, it needs to move the mouse to a specific point on the window. Is there a function that can move the mouse to a coordinate?
thanx..
KOM UIT DAAAAA!!!

You can use the SendInput function to move the mouse to any place on the screen. When using the function notice that the screen coordinates(resolution) have to be converted to mouse coordinates(0-65535) in both the horizontal and vertical directions.

What are the other parameters the SendInput function takes?

I'm working on a program that tracks my stats as I'm playing online poker. The stats portion if working fine, now I want it to display bitmaps of my chosing on top of the poker window as I'm playing. I can get a handle to the window using FindWindow... is it possible to display the bitmap in the poker window using this somehow? If so, would it just be overwritten by the actual poker app as it also displays it's graphical info to the same window?
Any other ideas?
Thanks!

Once you use FindWindow to locate the correct hwnd for the poker window, you're most of the way home. Rather than trying to paint your bitmap in the DC for that window, which could very well run into the kinds of problems that you anticipate, consider instead creating a new child window using the poker hwnd as the parent. That way you'll have complete control and can paint what you want in your child window without worrying about what the poker app will paint. You can set yours to be a floating window or any number of other options, but I think this approach will give you the most flexibility.

It may not be the approach they took since it's their app and they have control over who paints to the DC and when. However, if you want to superimpose your images over theirs and try to simply paint on their DC, you may find your work being overwritten by theirs since you have no way of determining exactly when and where they paint things.
You might try experimenting with both approaches and see what works best for you.

Hello,
have someone any Idea how to spy mousebutton clicks (No, not the normal buttons, one of the extended buttons, my mouse have 7 of them) with LibUsb http://libusb-win32.sourceforge.net/ , maybe with some example code snippets ?
I have only found:
-some Linux code for the "kernel"
-some Dos/command line based apps.
But i found no trick to use it in a windows application, neither it do nothing or the mouse "hang" because all the data are not pass through the mouse driver.
regards
Peter

Hi!
I'm doing an application where I have to place wrapping text inside boxes.
It's an MFC single document view.
The problem starts when I zoom out or in:
CSize size = pDC->GetTextExtent(str);
size.cx will have different values depending on the zoom level.
I've read the documentation and GetTextExtent() it's suppose to work on Logical units, so I don't understand what is going on.
That's a big problem because I do the wrapping myself (i have rotated text) and the wrapping changes when zooming.
Help please!!! I've been working on this 3 days now!!

what do u mean zoom in/out?
e.g. original font height is 8, when zoon in as 50%, u set font height as 4?

When you zoom in, fonts get bigger. So if you zoomed in by 50%, the font size would be 12. If you zoomed in by 100%, the font size would be 16.
