Hi!
I've been playing around with custom command routing a bit, and I've noticed that if you route a command message to a custom object, object.OnCmdMsg(...), and the function returns TRUE(saying it has handled the message and called the message handler), but I return FALSE instead (saying the message hasn't been handled), the command handler for the custom object is never called (even though it already should've been called(?)).
I hope someone can give me an explanation on why the handler isn't being called, and that the description above isn't to messy

This is the correct behaviour. MFC knows nothing about your custom object, even though you do. MFC checks to see if the current view handles the message. If it doesn't, it sends it to the current document. If the document doesn't handle it, it sends it to the current frame, the main frame (in an MDI application), and finally to the application if necessary. It never looks below the view.

Hi
I tried to make a dialog resizeable by changing its style using SetWindowLong:
<br />
CWnd* wnd = blablabla<br />
<br />
DWORD style = ::GetWindowLong(wnd->m_hWnd, GWL_STYLE);<br />
style |= (WS_THICKFRAME);<br />
::SetWindowLong(wnd->m_hWnd, GWL_STYLE, style);<br />
wnd->SetWindowPos(NULL, NULL, NULL, NULL, NULL, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);<br />
When I move the mouse cursor above the frame of the window I manipulated with this code the cursor changes to a resizing cursor, but I can't resize the window.
Then I found out, that this code only works, when I add a minimize or maximize button in the ressource editor.
So I changed the line in the code to:
style |= (WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX);
But this also doesn't work.
Please give me the solution to this problem
Thx a lot
Dave

Hi
I'm getting crazzy
I wrote a (very) little test-program for you. It's just a dialog with a button on it. When you click on the button it does nothing but calling
the function.
ModifyStyle( NULL, WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX, SWP_NOSIZE | SWP_NOMOVE );
As I said the window isn't resizeable after that, but the cursor changes to a resizing cursor.
I'm using Win2k, but I don't think that this makes any differences.
Could you please download the program and test it on your computer, wether it works or not. Perhaps this helps me to get the solution.

Thanks for your Consideration.

Hi
As Spy++ said "Internet Explorer_Server" isn't the child of a main window.
There does exist "Shell Embedding" and "Shell DocObject View" as its parents.
My question is: how can i simulate a mouse click to the "Internet Explorer_Server" controll?
I can't use the mouse_event function because the window i want to hit may be minimized or invisible.
I recognized that there are lots of massages send to the main window and its children when I click on the control.
Can you help me?
Thx a lot
Dave
ps. sorry for my bad english

Send it WM_LBUTTONDOWN and WM_LBUTTONUP messages.

Hi !
The Problem is this...
I want to login to a remote machine through a program using vc++/c++. I have administrator privilages of remote machine i.e. username and password are known in advance.
Can it be possible to pass the username and password as parameters to any API(if exists)or in any user define method.
Thanks in advance !
bye

logging in can mean a lot of things. What do you intend to accomplish?
Do you want "remote desktop" abilities? If so, the machines have to be XP, 2000Server, or 2003Server (I think)... and then is available by an ActiveX control...
Other types of access are available programaticallly...
But it's not clear what exactly you are looking for....

ok
this is what i want to do.
In my programs I am using some windows apis like(RegConnectRegistry,RegOpenKeyEx,GetFileVersion etc)to connect remote registry
or getting any information from remote machine.
These APIs works only when I login to remote machines using their username and passwords.
This thing i want to do programmatically, any program or api that can use username and passwords of remote machines.

oh.
And I take it that you are not operating in any sort of domain environment, where priveleges, access, and passwords are centrally administered. If you were, these API's would work assuming that you had actual access priveleges.
So, you want to arbitrarily be able to connect to a machine, with their known credentials, and make the connections to these remote APIs.
That I don't know the answer to.
Take a look through "Network Management" portion of the platform SDK.

Hi,
is it possible to check if an external application has been started, in Windows 98/NT/2K? This application runs in background mode (silent mode), i can see it only in processes tab of Task manager.
I am programming with (ANSI) C.
Thanx in advance,
Aenaos

One solution is FindWindow().

Have you looked at EnumProcesses() and related functions?
|
|
|
|

if it's a program that you control, consider adding a mutex with a global name.
The external app creates it, your program checks to see if it's in-use (running from that other program). This way is handier than EnumProcess -- if you ever change the names of programs, you don't have to rename your mutex.
-p
see CreateMutex and WaitForSingleObject API's.

I'm trying to align a struct like so:
<br />
__declspec(align(16)) struct myStruct<br />
{<br />
char a;<br />
int b;<br />
short c;<br />
};<br />
and i get align is undefined when trying to compile.
I even copied the sample from MSDN and had no luck.
Anyone knows what's the problem? Is it a compiler switch
not used? Or only used in VC7?
thanks

The align declspec option is not supported in VC6. Try using the #pragma pack() option instead:
#pragma pack(push, 16)
struct myStruct
{
char a;
int b;
short c;
};
#pragma pack(pop)Hope this helps,

thanks for replying, I was afraid it was the answer, however,
MS didn't say it's not for VC6.
anyways, I also saw this option (pragma pack) but it doesn't
allow me to go over 32 (align goes to 4k if I'm not mistaking).
so is this the final answer?
|
|
|
|

#pragma pack(push, #) does not allow you values other than:
1, 2, 4, 8, and 16.
It's pretty bad

Yeah, I don't think the two options are identical, they are used for different things, but have similar effects.

Hello,
I am trying to dynamically change the texts of the menu items of my main menu. The program should translate the menu items to the local language at runtime. I am using the BCMenu class:
UINT nItem = 0;
CString strItem;
CString strNew;
char *pszSrc = NULL;
while(1)
{
if(m_menu.GetMenuText(nItem, strItem, MF_BYPOSITION) == FALSE) break;
pszSrc = strItem.LockBuffer();
strNew = TRL(pszSrc);
strItem.UnlockBuffer();
if(m_menu.SetMenuText(nItem, strNew, MF_BYPOSITION) == FALSE) { ASSERT(FALSE); }
MessageBox(strItem + " -> " + strNew);
nItem++;
}
m_bMenu = SetMenu(&m_menu);
ASSERT(m_bMenu == TRUE);
The TRL function takes a char * as input and returns a char * to the translated string. This works very well as one can see in the dislayed message box (strItem+"->"+strNew).
The items are translated correctly, but the menu doesn't change. The menu items remain english, untranslated. But the SetMenuText function returns TRUE...
Any idea what is going on?

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

call DrawMenuBar() for the window. From MSDN:
Redraws the menu bar. If a menu bar is changed after Windows has created the window, call this function to draw the changed menu bar.
Hope this helps,

Nope, that doesn't help. I've changed my code now a bit:
UINT nItem = 0;
UINT nSub = 0;
CString strItem;
CString strNew;
char *pszSrc = NULL;
BCMenu *pSubMenu = &m_menu;
while(1)
{
nItem = 0;
while(1)
{
if(pSubMenu->GetMenuText(nItem, strItem, MF_BYPOSITION) == FALSE) break;
pszSrc = strItem.LockBuffer();
strNew = TRL(pszSrc);
strItem.UnlockBuffer();
if(pSubMenu->SetMenuText(nItem, strNew, MF_BYPOSITION) == FALSE) { ASSERT(FALSE); }
nItem++;
}
pSubMenu = (BCMenu *)m_menu.GetSubMenu(nSub);
nSub++;
if(pSubMenu == NULL) break;
}
m_bMenu = SetMenu(&m_menu);
ASSERT(m_bMenu == TRUE);
The items in the menu (so for example all items in "File", such as "Exit") are translated and shown correctly!
It's just the "main main" menu bar (so the one with "File", "Extras", "View", etc).
The code snippet above is called in OnInitDialog.
Any more idea?
