It looks like a BHO.
There are many resources available here on CP about BHOs. You can search for "BHO" (Browser Helper Object).

I may be wrong but it seemed like a nasty addware. I removed it by using HijackThis. Then there was no Applet in Add/Remove programs. (it seems).

this is this.

You could write another program (exe) that will open the dll file using LoadLibrary(), update the resources using BeginUpdateResource(), UpdateResource(), EndUpdateResource(), then FreeLibrary().
The program could find all the files in a designated directory, put the files in the dll using the above functions, and that would be it.

this is this.

CEdit transparent background - text gets screwy

Christian Graus8-Dec-05 11:48

I'm trying to draw an edit control so you can see the background, so I'm drawing it transparently, drawing the background I want and invalidating it whenever it seems necessary. I've tried returning a null brush and returning a pattern brush from WM_CTLCOLOR. It all works great, until I use the arrow keys. If I type over the text that is being edited, the old text remains in place, although my invalidate call is working. I have found samples that work on the web, and I don't see how my code is different, does anyone have any clue ?

G'day, PJ

OK, in the first instance, the samples I found just passed back a transparent brush and set transparent mode in WM_CTLCOLOR ( as you also suggested ), and then called an Invalidate on the area in the parent when the mouse was clicked, or text is updated ( EN_UPDATE, from memory ). This worked in the samples, but not for me. I initially draw my background in WM_PAINT, but moved it to WM_ERASEBKGND, and the overall effect was great, excepting that if I used the arrows, or tried to select, no text was ever erased, it just went over itself.

So, I changed the code to use WM_PAINT again ( I tried going back and it doesn't work ), and I basically just draw my background, then draw the text over the top. I also need to figure out the selected area, and redraw that with a solid background, and now it all looks great.

Hi,
I am doing a project in win32. When I start the app, I want to find out the details of all the monitors that are connected to the system. ie. the windows monitor number, if it a usb or serial monitor, etc...
I am doing the following...

<br />
 hDevInfo = SetupDiGetClassDevs(NULL,<br />
        REGSTR_VAL_DISPLAY, // Enumerator<br />
        0,<br />
        DIGCF_PRESENT | DIGCF_ALLCLASSES );<br />
<br />
    DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);<br />
    for (i=0;SetupDiEnumDeviceInfo(hDevInfo,i,<br />
        &DeviceInfoData);i++)<br />
    {<br />
        DWORD DataT = REG_SZ;<br />
        LPTSTR buffer = NULL;<br />
        DWORD buffersize = 0;<br />
	    while (!SetupDiGetDeviceRegistryProperty(<br />
            hDevInfo,<br />
            &DeviceInfoData,<br />
            SPDRP_LOCATION_INFORMATION ,//, SPDRP_DEVICEDESC SPDRP_FRIENDLYNAME <br />
            &DataT,<br />
            (PBYTE)buffer,<br />
            buffersize,<br />
            &buffersize))<br />
        .........<br />

but how can I find out the windows monitor number, and some other details like serial/usb of model number etc...

class subclass instance problem

Hallo

newbee confused

Ok i have a class car.h and a class carpark.h looking like this:

<br />
#include "car.h" // not important<br />
<br />
class carpark  <br />
{<br />
public:<br />
	carpark(int size);<br />
	~carpark();<br />
	<br />
	void insert(car *p1);<br />
<br />
	class Iterator;<br />
	friend class Iterator;<br />
	<br />
private:<br />
	car** array;<br />
};<br />
<br />
class carpark::Iterator<br />
{<br />
public:<br />
	Iterator(carpark &cp);<br />
	~Iterator();<br />
<br />
	void reset();<br />
	void next();<br />
	car* get();<br />
//private:<br />
	carpark &c;<br />
<br />
};<br />

Now how to implement Iterator ???

<br />
carpark::Iterator::Iterator(carpark &cp)<br />
{<br />
	c = cp;<br />
}<br />

this throws some error i dont understand
"'c' : must be initialized in constructor base/member initializer list"

and while using the defaultconstructor
i can't access the functions from Iterator

<br />
int main()<br />
{<br />
...<br />
	carpark::Iterator it();<br />
	it.reset(); // throws error "must have class/struct/union type"<br />
...<br />
}<br />

What to do - or where to read about something like this

Please Help Confused | :confused:

Hello,

A constructor initializers list is a special place for initializing member variables of a class. The following example solves your problem:

class carpark::Iterator(carpark& cp)
              : c(cp)  // this here is the initializer list
{
}

I assume that you know how to implement the iterator, but here's one little tip for the road: your next() function should return a bool. This makes it more easy to iterate through your carpark:

// This is more conveniant
carpark cp;
// some code

// iterate 
carpark::Iterator iter(cp);

// do something with first car
if( /* are cars in carpark */ )
{
    // do something 
    // iterate over all other cars in park
    while( iter.next() )
    {
        // do something with other cars.
    }
}

Actually I hooked it with the purpose of hiding a file. But as far as I could see the explorer makes a lot of calls for FindNextFile and it eventually crashes.
How can I hide the file though or how can I fix this pb.
I get the same pb when I hook CreateFile the explorer craseh immediatelly.
