I would have to say that this is one of the cases that you may want to use the DDX_ functions. One of the overrides does exactly just that.
But there are limitations to those functions so if you are hitting on those limitations, you may still have to roll your own code.

Hi!
Me and a friend are trying to build a robot that communicate with the computer using the parallel port.
I have used the outp() command before but I do not want to use the port address since I have experienced problems on different computers when the address are different.
So I have heard I can use WritePrinter to send data to the parallel port. But All I get when I try to use it is trouble. When it seems like I have everything right I get linker error (2001 I think not sure though). So what I need is a complete guide for how to get this to work since I am not into this win32 API stuff att all.
I use MFC visual c++, and am running Win ME.
examples are appreciated
Thanks,
hywer

I found a <http: www.codeproject.com="" script="" comments="" forums.asp?forumid="1647&app=50&kw=colors&select=98566#xx98566xx"" target="_new">thread from a few days ago about getting a CListCtrl to draw more than 16 colours from its associated CImageList.
CBitmap bitmap;
bitmap.LoadBitmap(IDB_CERT_PG);
m_pImageList = new CImageList;
m_pImageList->Create(16,16, ILC_COLORDDB | ILC_MASK, 2,2);
m_pImageList->Add(&bitmap, RGB(0,0,0));
m_pImageList->Add(&bitmap, RGB(0,0,0));
m_listctrl.SetImageList(m_pImageList, LVSIL_SMALL);
The CListCtrl draws the bitmaps in 16 colours. I have tried setting up a halftone palette, but that didn't work either. Am I going to have to override CImageList's OnDraw() to draw the bitmap myself in over 16 colours?

That's the problem - ILC_COLOR24 doesn't work. CListView still insists on 16 colours.

Hi!
I've tried to get my app to do what Start->Run does, but failed. The string entered in the Start->Run editbox must be passed to some function in a dll somewhere. Does anyone know which?
ShellExecute(), CreateProcess() and system() won't do.
|
|
|
|
|
The "Start->Run" doing nothing but simple ShellExecute(). What you mean that it isn't working? So or you passed wrong parameters to it or the path doesn't exists.
Post an example of what are you doing with ShellExecute()

hWnd is a common editbox
int commandLength = ::GetWindowTextLength(hWnd);
LPTSTR szCommand = new TCHAR[commandLength + 1];
::GetWindowText(hWnd, szCommand, commandLength + 1);
LPTSTR szParameters = strchr(szCommand, ' ');
if (szParameters)
{
szParameters[0] = '\0';
szParameters++;
}
::ShellExecute(NULL, NULL, szCommand, szParameters, NULL, SW_SHOWNORMAL);::SetWindowText(hWnd, TEXT(""));
delete[] szCommand;
The command is run, but if I type an errouneous command, no errormessages are displayed. I would like ShellExecute to do that for me. I've tried several different parent-window handles as parameter, but no messagebox are displayed.

ShellExecute doesn't do the messagebox for you.
You need to check the return value and then display a messagebox by yourself

I have "simple object",when I created it I accepted all default attribute.
Now I want to add Method with "callback" attribute,but after compile it return error:
method definition--->[id(4), helpstring("method KeyboardProc"), callback] HRESULT KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam);
error---->error MIDL2304 : attribute invalid on a proc in an [object] interface : : [callback] [ Procedure ...
I also test this and get this error:
method definition--->[callback(4), helpstring("method KeyboardProc")] HRESULT KeyboardProc(int nCode,WPARAM wParam,LPARAM lParam);
error---->error MIDL2025 : syntax error : expecting ] or , near "("
***I also want the return vale to be "LRESULT" but I can not change "HRESULT" when I want to add Method.*****

I'm not quiet sure what you are trying to achieve here.
COM IDL is limited to certain data types and callback certainly isn't one of them. COM methods can only return HRESULTS, if you want to return a value it needs to be passed back as a pointer via the parameter list.

If you look up error 2304, it reads;
MIDL2304: attribute invalid on a procedure in an [object] interface
The specified attribute is not allowed on procedure in a COM interface.

Hi, I was wondering if anyone out there knew of a place where I might either buy or obtain (open-source) a copy of an "intellisense" control, similar to that of Visual Studio? I am in the process of working on an editor and such a control would be awesome.
|
|
|
|

Didn't understand your post at all, lmao. But according to Subject, I see you want an Autocompletion.... The only thing.... Not ListBox, but ComboBox..
Well, look in MSDN for interface IAutoComplete
Hope this is what you want

Hi, thanks for replying, however, I was trying to ask whether a "popup intellisense menu" existed as separate control. You know how in MSVC, after you type a "." or a "->", all the class members of the object you are dealing with will be displayed? I would like to incorporate "intellisense" into my very own, homegrown editor.

Try this:

LEt me know if you have any questions on usage.

What's wrong with the following?
#include <vector>
class kConfig
{
protected:
public:
typedef int (*cheese)(void*);
struct kconfig_handler{
char* settingName,
cheese handlerFunc,
void* pObject;
};
kConfig();
~kConfig();
void registerHandlers(kconfig_handler[] handlers);
int loadConfig(char* pchFilename);
private:
std::vector< kconfig_handler* > m_settingList;
};
I keep getting this error when i try to compile:
f:\software\katie\include\kconfig.h(24) : error C2146: syntax error : missing ';' before identifier 'handlerFunc'
That error refers to the line
cheese handlerFunc,

struct kconfig_handler {

};You have commas there instead of semicolons.

No wonder, and to think I make structs all the time. How could that have happened? I guess age has caught up with me (17 years).

Heh, I type , instead of ; in for loops all the time and it bugs the heck out of me.
