you do really sound like a bad hacker...
but let's assume u'll use this for an installer:
you could add files as resources(if they aren't very big), then use your software to extract them.

Relax guys. im not going to write a virus and im certinly not a hacker
all im trying to do is a basic multi installations file that will run several installations file depending on the conditions of the system and the server which runs the installations without any user interference. this could have been solved in simple bash script if it was unix.
but since i need it running on windows clients i would have to use a c solution.

Hello,

Does anyone have any pointers to articles about making a multi-line list control? I've searched here and cannot seem to find this specific issue.

thanks! JennyP

I've written one, but that was for work, so I can't post code.

As I recall, I handled WM_MEASUREITEM to reflect the number of lines I wanted, then handled either NM_CUSTOMDRAW or WM_PAINT to paint the text (I can't recall). This was on Windows CE, so you might need to do things differently. This technique only works if all items are the same height, though - that is, they have the same number of lines.

What is the best way to open a image file and get
access to the raw bytes of the image so that I can
apply various algorithms from Intel's IPP library.

Also what about allocating the wright ammout of memory?
Can I just use GetFileSize or the like to get the required
size of the buffer?

Thank You
Bo Hunter

depends on what kind of image you want to load...
loading a BMP file is really easy, you have to read the header, allocate memory for the bitmap and read the rest of the file.

Get the menuitem which was pressed

Wim Jans17-Jan-04 10:58

17-Jan-04 10:58

Hello all,

I'm having difficulties to get the string of a menu item pressed.
What I'm doing is writing a IE toolbar and in one of the pull down menu's I dynamically add popup menu's which are also dynamically filled.

Just for a theoretical example let's say I have a button 'drives' on the toolbar. Pressing the pulldown menu will add some menu entries (the same amount of disk on my system, C; D; E; ...).
Every menu item is a popup itself, and a dynamically created Popupmenu is attached - containing the root level directories for the selected drive (temp, program files, winnt, ...).

Following is an adapted piece of code, but it works how it suppose to

	<br />
MENUITEMINFO mmi;<br />
mmi.cbSize=sizeof(MENUITEMINFO);<br />
mmi.fMask=MIIM_STRING | MIIM_DATA | MIIM_SUBMENU;<br />
<br />
char fn[50];<br />
<br />
// 3 drives in the example<br />
for (int i=0; i<3; i++)<br />
{<br />
    HMENU hMenuToInsert;<br />
    hMenuToInsert = CreatePopupMenu();<br />
    {<br />
	char drv[255];<br />
	while (getthedrives)<br />
	{<br />
	  sprintf( drv, "%s", a_directory);<br />
	  AppendMenu(hMenuToInsert, MF_ENABLED|MF_STRING, ID_DUMMY, drv);<br />
	}<br />
    }<br />
    sprintf( fn, "Drive %s", drvletter);<br />
    mmi.hSubMenu = hMenuToInsert;<br />
    mmi.dwTypeData = fn;<br />
    mmi.fType=MFT_STRING;<br />
    //insert the drives <br />
    InsertMenuItem(m_hDriveMenu, 2+i, TRUE, &mmi);<br />
<br />
}<br />

The problem I'm having is, is that I'm using a dummy ID (ID_DUMMY).
When my ON_COMMAND fires, I have no way to get the correct menu item using GetMenuItemInfo because
a) I'm using the same id for every popup menuitem inserted
b) I'm reusing the HMENU (hMenuToInsert) for my popmenu's

Does anyone know of a simple way to get the text of the menu (directorys on a drive in my case) pressed?

Thanks

Wim

Why are you using the same ID for every menu item? You're defeating the purpose of IDs by doing that.

Hi Michael,

I'm reusing them because I really have no clue how many directories I will have.
Let's say I have 10.000 directories, that means I have to define 10.000 unique id's. You know of a way to create that many on the fly, or maybe a better way to do it?
The other problem I have then is to what popupmenu the directory I clicked belongs (C:, D:, E Smile | :)

, but I supppose I can have a list of HMENU id's and I check every list/MENU_ID for success.

Thanks

Wim

Well, command IDs can be in the range 1-65535. Just start a counter a 1 and increment it for every menu item you add. Each menu under the first level can use 1-65535, you don't need a unique ID for every single item if you think you'd ever have more than 65535. You can tell which top-level popup has been selected by handling WM_MENUSELECT, and from there you can work out which directory was selected.
You should also give the top-level popups IDs for easier tracking (and those IDs shouldn't be duplicated in the submenus). You can do this with InsertMenuItem().

Re: Get the menuitem which was pressed

Wim Jans18-Jan-04 8:48

Ok,

I see it now. One thing what I discovered when playing with the WM_MENUSELECT was that I couldn't get the (a random) text from my popup menu (just for a test, take the first entry of the popupmenu, I will move it to the WM_COMMAND later).

What I did was this:

<br />
LRESULT CMyToolBar::OnMenuSelect(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)<br />
{<br />
	if (lParam&&(HIWORD(wParam)&MF_POPUP))<br />
	{<br />
		HMENU hSubMenu = GetSubMenu ( (HMENU)lParam, LOWORD(wParam));<br />
<br />
		MENUITEMINFO mii;<br />
		mii.fMask = MIIM_STRING;<br />
<br />
		char c[2000];<br />
		mii.dwTypeData=c;<br />
		mii.cch=2000;<br />
<br />
		GetMenuItemInfo(hSubMenu, 0, TRUE, &mii);<br />
		MessageBox(mii.dwTypeData);<br />
	}<br />
	return 0;<br />
}<br />

According to the documentation, lParam contains the Handle to the menu I pressed (the main menu), and if HIWORD(wParam) contains flag MF_POPUP, the LOWORD(wParam) contains the the position pressed in the menu.

If I use GetSubMenu((HMENU)lParam, HIWORD(wParam)), I should get the handle to my popupmenu containing the directories, right?
I outputted the parameters, and the handle and index looked OK.

But when I used GetMenuItemInfo using the handle obtained with GetSubMenu and index 0 (the first Item in the popup menu), it returns an empty string.

Any idea what I'm doing wrong?

Thanks

Wim

Get default proxy (from IE)?

Hi, I wrote an application which connects via an HTTP proxy. Can I get the default proxy from the system (hostname and port)? Alternatively can I get it from IE?

Hi,

There is not such a thing as the system proxy. WinINet functions are tied to IE, and it is IE settings that you can get and set with this library. Take a look at InternetQueryOption documentation.

UCS-2 to UTF-8 and reverse

Hi!

I need to convert a TCHAR* string (which actually can be a char* or wchar_t* string) to UTF-8 format and the other way round.

I cannot use the MultiByteToWideChar and WideCharToMultiByte functions.

Is there a small, tiny library that does this? I've had a look at IBM's ICU, but this library does much too much, I don't need all those additional conversion functions, etc.

Or is there perhaps a simple method how I can do the conversion myself?

Thanks in advance!

_outp(0x64, 0xAD);
