How to detect the browser version?

4-May-05 3:05

This works fine for me:

char szBuffer[64];
HMENU hMenu = GetSystemMenu(hWnd, FALSE);
GetMenuString(hMenu, 0, szBuffer, sizeof(szBuffer), MF_BYPOSITION);
GetMenuString(hMenu, 1, szBuffer, sizeof(szBuffer), MF_BYPOSITION);
GetMenuString(hMenu, 2, szBuffer, sizeof(szBuffer), MF_BYPOSITION);

Dear all,
How to detect what kind of browser is running and its version? For example, Netscape or IE; IE 5.0 or IE 6.0, ect.
Best regards,

Your question cannot be answered in its current form (as more than one browser can be installed at any given time). If you want to know the default browser, simply use FindExecutable().

Yes, just use GetFileVersionInfo() and VerQueryValue().

Hiya

I know this may be a VERY stupid question... but I have tried to find a way to toggle on the line numbering in MS Visual C++ 6.0... no success... anyone?

Cool | :cool:

Thanks!

No such option exists. The only way to know what line the cursor is on is by the Line/Col indicator down in the lower right corner next to the keyboard status indicators.

PopUp Menu

Hi everybody,

I have created an PopUp Menu in a CDialog...it works OK.

Now I want to create a PopUp Menu inside an ActiveX every time I click Button RIGHT of the mouse...
I have copied the code inside the function WM_RBUTTONDOWN...The problem is that it shows the Menu but it is DISABLED (it is shown but I can not select an option).

How can I do it to solve it...to make it enable?

Thanks

Here the code :

HMENU hMenu = ::CreatePopupMenu();
if (NULL != hMenu)
{
// add a few test items
::AppendMenu(hMenu, MF_ENABLED | MF_STRING & !MF_GRAYED, 1, "Change Color");
::AppendMenu(hMenu, MF_ENABLED | MF_STRING & !MF_GRAYED, 2, "Hide");
::AppendMenu(hMenu, MF_ENABLED | MF_STRING & !MF_GRAYED, 3, "Item 3-");

ClientToScreen(&point);

int sel = ::TrackPopupMenuEx(hMenu,
TPM_CENTERALIGN | TPM_RETURNCMD,
point.x,
point.y,
m_hWnd,
NULL);

CString s;

s.Format("The selected item is %d", sel);
TRACE(s);

:estroyMenu(hMenu);

These parts are not necessary, and will actually screw it up and make it not work.

How to implement delay

How do I implement 'delay' in VC++?
I also need to find out a way to get the "time elapsed" between two commands like when the data on the serial port goes high.

Can some one also give me info on the following -
GettickCount
Dword
VERIFY
ASSERT
dwcount

Thanks in advance.

Sleep is the command to make your app stop for a bit.

hithesh wrote:
GettickCount

The GetTickCount function retrieves the number of milliseconds that have elapsed since the system was started. ( first hit on google )

hithesh wrote:
Dword

A DWORD is an unsigned long. It's a really big number.

hithesh wrote:
ASSERT

An ASSERT is a construct that will fail if the condition you pass it fails. This means that in debugging, you can check the assumptions that your code makes about the state of your application at any point. It is not included in release builds, and should be used for debugging only.

hithesh wrote:
dwcount

Is probably a variable called count, that is of type DWORD, and has been created using Hungarian notation ( where the first few letters of a camel case variable name denote the type of the variable )

Christian, Thanks for the answers.
For the delay, I knew about sleep. I need something thats similar to a timer.

like -

1. when a bit goes high
2. start timer
3. stop timer when the bit goes low.

Sleep is used when you know the amount of delay you want, right? If this is not right, plz gimme an example.

Yes.

I don't know of any way to do this without implimenting it yourself, unless there's a variation on WaitForSingleObject that waits for a memory location to change. I'd imagine the thing to do is use sleep to sleep for small amounts of time, and then check your bit inbetween.

chris,

How about settimer()?
I can't use sleep because, I am trying to find out the time duration during which the input is high and also the time duration during which the input is low. This is from the serial port which receives the Infra red signal from the TV remote. Then, I send the same signal out. Its kinda like learning.

Christian Graus3-May-05 14:46

3-May-05 14:46

Oh, OK. I've done stuff like that before. Yes, I used SetTimer inside my class that watches the serial port, and you can use a get time function to get the time before and after, to work out an interval. My code was in C#, and I was using the serial port as an input device.
