Is it possible to restrict the screen area that a child process can occupy? For example, say I want a child process window to only occupy the area between 0,100 to 800,600 the window can not go outside of these bounds if the user tries to maximise or resize or move the window.

that would require having access to the source code of the app I want to launch, which i don't.
thanks anyway

hi everyone. i have some simple questions for the cp windows pros out there
im developing an MFC app, and basically the area where my questions
for advice apply, is my startup functionality.
i need to
a) put the app into startup, and remove the app from startup on the fly.
im hoping someone can point me to a nice, easy object or api to provide this functionality to me. would really appreciate some direction here...
b) I have a dialog app. got my Capp class and all the good stuff that comes w/ it. I basically need to know in my code before the window is drawn, that my app was started from system startup, as opposed to being ran by the user so i can do some extra stuff in this case. On startup i'd like to pass some special parameters to the app so it can act a little different for me on a system startup run. any suggestions here would be great.
thanks in advance !

Add your application path under following resitry key
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
first check it sing Regedit.exe utility ( comes with windows) U can add path using Registry related APIs like RegOpenKeyEx and RegsetValueEx
this will add ur app to startup
hmmm.. for second thing wat u can do is that write the system time to registry when ur app starts.. but first check that since when is ur system up and if the value there in registry is older than that it means it is being started at system startup otherwsie by some user.

b) When you update the aforementioned registry key with your application, add a command-line parameter. When the user starts your application from Start/Run, or from within Windows Explorer, no such command-line parameter will be provided.

I have some code here that is supposed to swap bytes in a word. For some reason it has a bug in it in the ByteSwap2 function or the ByteSwap_c function. It's getting very frustrating and time is running out. Can anyone help me..?
The main is on the bottom of the code.
Thanks.
B
void ByteSwap2_c(int n, short *a)
{
int i;
for (i=0; i<n; ++i) {
short int tmp=a[i];
short int pmt;
((char*)(&pmt))[1]=((char*)(&tmp))[0];
((char*)(&pmt))[0]=((char*)(&tmp))[1];
a[i]=pmt;
}
}
#include "stdio.h"
void ByteSwap2_c(int n, short int *a);
void ByteSwap2_asm(int n, short int *a);
void ByteSwap2(int n, short int *a)
{
int i;
short *b = (char *) malloc ( n * sizeof(short int));
for (i=0; i<n; ++i)
b[i]=a[i];
ByteSwap2_c(n,b);
for (i=0; i<n; ++i) {
if (a[i] != b[i]) {
printf("a[%d] (0x%04X) != b[%d] (0x%04X)\n",i,a[i],i,b[i]);
exit(1);
}
}
free(b);
}
void test2(int n, short int *a, short int *b)
{
int i;
ByteSwap2(n,a);
for (i=0; i<n; ++i) {
if (a[i] != b[i]) {
printf("a[%d] (0x%04X) != b[%d] (0x%04X)\n",i,a[i],i,b[i]);
exit(1);
}
}
}
int main()
{
static short int a[4]={0x0304, 0x8999, 0xef12, 0x5678};
static short int b[4]={0x0403, 0x9989, 0x12ef, 0x7856};
test2(4,a,b);
printf("all tests pass\n");
}

If you are looking for a simple byte swap.
You could try
void _swab( char *src, char *dest, int n );
in <stdlib.h>
hope this helps

While you'll get great advice here (assuming you ask the right question), folks are not too fond of bug hunts. What exactly is the problem? What are you trying to do? Are there compiler/linker errors? Have you single-stepped through the code to see what is happening at run-time?

Hi,
I have a sdi program. In the view's OnCreate function, I create a toolbar and a browser control in the view's client area. Now, if the view loses focus, the toolbar is inactive(grey). But I want the toolbar always active. How to do now?
Thanks.

Handle
UPDATE_COMMAND_UI message for your particular toolbar.
CFrameWnd::OnUpdateButtonsInYourToolbars(CCmdUI* pCmdUI)
{
pCmdUI->Enable(true);
}
Hope this helps

Thanks. I find another way in MSDN to solve the problem.
To allow ON_UPDATE_COMMAND_UI handlers to work for other status bar panes and for toolbar buttons, you must derive new control bar classes and implement a message handler for WM_IDLEUPDATECMDUI. This is necessary because the default control bar implementations of OnUpdateCmdUI() assume the parent window is a frame window. However, it doesn't do anything but pass the parent window pointer on to a function that only requires a CCmdTarget pointer. Therefore, you can temporarily tell OnUpdateCmdUI() that the parent window pointer you are giving it is a CFrameWnd pointer to meet the compiler requirements. Here's an example:
LRESULT CMyToolBar::OnIdleUpdateCmdUI(WPARAM wParam,LPARAM lParam)
{
if (IsWindowVisible())
{
CFrameWnd* pParent = (CFrameWnd*)GetParent();
if (pParent)
OnUpdateCmdUI(pParent, (BOOL)wParam);
}
return 0L;
}

Your codes is neccessary if your handler is not in the CMainFrame (derrived from CFrameWnd).
If your handler is the in CMainFrame. It should be okay of just handling the OnUpdateCmdUI.

I had an SDI with some dialogs and through user inputs in the dialogs, i show my graphics in the SDI view using OpengGL rendering.But I was wondering why windows doesn't auto-refresh the view for me because as my dialog is in front of my view, whenever the dialog is shifted or moved, a white patch of the dialog'outline will overlap onto my graphics in the view... I do not know how to refresh my view again in this case...can anyone help?

You will have to re display ure image in this cse .Use OnPaint event handler for this.
No Worries!

thanx for replying. Can u elaborate on how i can re-display my image properly? My OpenGl coding was done in the dialog.cpp, then i should code the re-display in the view class OnPaint handler? I tried the following in the View class ONPAint message handler but unable to work:
Void ProjectView:: OnPaint()
{ CPaintDC dc(this);
InValidate();
UpdateWindow();
}

I need a real function that will create real random numbers, it should be able to be used in old-style c++, you know, console c++. lol

This is a small one to generate a seed.
void MyRandomize()
{
static unsigned int t = 0;
SYSTEMTIME st;
GetSystemTime( &st );
unsigned i = (unsigned int)st.wMilliseconds;
i+=t++;
srand(i++);
}
then call the:
rand() % /*number*/ ;
from <math.h> "I think"
APe

|

Not sure exactly what this is doing, but it appears way too complicated. Calling srand(time(NULL)) is sufficient for seeding the random number generator.
