Does any one have any idea if GDI+ or the XP OS extends the size of a DIB in the GDI to better then 32K ?
Thanks in advance

I've got my declaration of canal tree which has a static array of ID's of icons. I then derive another tree control class from canal tree called RPhysicalTree. I then derive andother class from RPhysicalTree called SacmanSetUpTree. When I compile, I keep getting a linker error. I've delcared and defined the array correctly. What's up?

Move the definition of the array to a CPP file. The way it is currently, one m_icons array is defined for every CPP file that includes that header, which leads to the linker error

Hi:
I'm beginner in activex programming with VC++ and i have a problem!
How can i create a multi-choice property for an activex control !!!!?
for example suppose an activex have a property with following features (through ClassWizard)
External Name : BorderStyle
Type : CString (for example)
Variable Name : m_borderStyle
Notification Function : OnBorderStyleChanged
Implementation : Member Variable (Radio Button)
and this property have some value such as (note that : more than three property !!! this is very important for me)
1) None
2) Flat
3) Static_Edge
4) Three_D
5) Button_Edge
6) Client_edge
and etc.
Now i want show this values in a drop-down list in the "ALL" Activex's property sheet and user select one of them
from it.
Please help me.
My english isn't very well, please excuse me for bad comments.
Thanks a lot.

I don't think you can directly....
Manually edit idl place something like:
typedef [uuid(8216ACE0-8C0F-40AF-AA1E-5E988573C582)]
enum {
[helpstring("1 - bsNone")] bsNone = 1,
[helpstring("2 - bsFlat")] bsFlat = 2,
[helpstring("3 - bsStatic_Edge")] bsStatic_Edge = 3,
.....
}BorderStylesConstants;
....
Change interface to look like...
[id(44444), propget] HRESULT SetStyle(BorderStylesConstants borderStyle);

Here is what I want to do
VB front end is main app
DLL # 1 creates an array of doubles
DLL # 2 performs some task on an array of doubles passed to it
Vb frontend will get a pointer to an array of doubles (double * array) from DLL #1 and pass the pointer to DLL #2 which accepts pointers to arrays of doubles.
How do I get VB to do this ie. recognize what a pointer to a array of doubles is??????
Thanks in advance for all help
|
|
|
|
|
Between dll's you can pass pointer like long value and inside the second dll you can assign this long to the real pointer and do the conversion
|
|
|
|
|
Thanks for the reply.
I thought about that but my ploblem is that the 2nd DLL(receiving the pointer) must have a (double*) as it's parameter. I can not redeclare the function to accept "void pointers". If I could, I would.
Any other suggestions?

Is it possible to add a hook to keyboard from a services
I want to add the hook when the service is starting and remove the hook when the service is stop.
I tried but the hook can not be installed.
Thanks
Florian

Yes you can, the only thing that you must consider is that a system wide keyboard hook must be placed inside a DLL.
Then you should create a DLL that contains the hook (the callback function) and remember that the service must have a mesage pump.
If you have more questions or if I have not been so clear, (or if I've completely missed the shot) don't mind to ask again.
Hope this helps...

Hi Everyone,
I have an application that is designed to load an image from the database. This image is in a compressed form like png, jpeg etc. I was wondering what is the process to loading the bitmap if it is already in memory (ie. not loading it from the disk)? Should I use something like FileMaps or something else?
Cheers,
Clint

|

there are a half-dozen articles on CP that handle image I/O. most of them can handle memory-based images. look in the "Bitmap and Palettes" section.

Hi Chris,
I did go through them, unfortunately they deal with their own classes. I would like to be able to use CImage (which supports decompressing png) from the MFC library. So what I need to know is how do I tell windows that this compressed png file is in memory and not on disk without having to save a temp file to disk?
Cheers,
Clint

i'm not familiar with CImage, but the MSDN says its Load method can take an IStream interface. so, you could hook up some kind of IStream-based COM object to read your memory-based image. (yeah, yuck)

How could I get the path of a APP.EXE ??
I need to open a Site with Internet Explorer browser. I have used the GetModuleFileName function, but I don't have the HMODULE parameter (to get HMODULE, the GetModuleHandle function also doesn't work).
Any idea ??
Thanks,
Cris.

Hello There!
If the app was put on your computer with an installer you don't need the path because it is registered in the registery automatically. You can just provide the name of the executable in ShellExecute(..) and it will launch the app.
However if you insist on getting the path use this:
char szRegBuf[200];
DWORD pcbData=199;
if(!::SHGetValue(HKEY_LOCAL_MACHINE,"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\TheExecutable.exe","Path",(LPDWORD)REG_NONE,szRegBuf,&pcbData))
{
AfxMessageBox("Successfuly located TheExecutable.exe path in the registry");
}
|
|
|
|
|
Ok, and abount the SHGetValue function ?? Where it is declared ??
[]'s
|
|
|
|
|
Hi Cris,
It is declared in Shlwapi.h.
Or you can use some other Registry access function if you want. I have the MSDN info for you if you wish. But once again you really don't need the path if you use ShellExecute(..) on an installed application.
Art
///////////////
From MSDN info
///////////////
SHGetValue
Retrieves a registry value.
DWORD SHGetValue(
HKEY hkey,
LPCTSTR pszSubKey,
LPCTSTR pszValue,
LPDWORD pdwType,
LPVOID pvData,
LPDWORD pcbData
);
Parameters
hkey
Handle to the currently open key, or any of the following predefined values: HKEY_CLASSES_ROOT
HKEY_CURRENT_CONFIG
HKEY_CURRENT_USER
HKEY_DYN_DATA (Windows 95 only)
HKEY_LOCAL_MACHINE
HKEY_PERFORMANCE_DATA (Windows NT only)
HKEY_USERS
pszSubKey
Address of a null-terminated string that specifies the name of the subkey from which to retrieve the value.
pszValue
Address of the value.
pdwType
Type of value. For more information, see Registry Data Types.
pvData
Address of the destination data buffer.
pcbData
Size of the destination data buffer.
Return Values
Returns ERROR_SUCCESS if successful, or a nonzero error code defined in Winerror.h otherwise. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to retrieve a generic description of the error.
Remarks
Note If your application must set/retrieve a series of values in the same key, it is better to open the key once and set/retrieve the values with the regular Microsoft® Win32® registry functions rather than use this function repeatedly.
Requirements
Version 4.71 and later of Shlwapi.dll
Windows NT/2000: Requires Windows 2000 (or Windows NT 4.0 with Internet Explorer 4.0 or later).
Windows 95/98/Me: Requires Windows 98 (or Windows 95 with Internet Explorer 4.0 or later).
Header: Declared in Shlwapi.h.
Import Library: Shlwapi.lib.

Is it possible to change the background color of a menu from white to gray eg. RGB(222, 222, 222) without having an owner drawn menu?

I doubt it. You could try temporarilly changing the control panel colors, but this would effect all aplications and menus.

You can do that with SetMenuInfo() and set a new background brush - only works on 98+ and 2000+ however.

Thats quite strange that it wouldn't work with XP. I tried it anyways but even though the class members where showing up when I was filling in my MENUINFO struct the program failed to compile because MENUINFO was not recognized...Does this have anything to do with me running XP (I doubt it, I think...) and windows.h is included.
Regardless, what are some better alternatives to take care of XP Windows and below?
