i have a combo box which contains interger values and i have couple of files in my application. i have mapped this combo box to integer. i am getting the index of the value and i am using cstring to convert it to the original value. for ex. there are 2 values in my combo box. 100 and 200. if i select 100 i get the index as 0. and the CString variable will return the value(100). now my requirement is i need to pass the value(100) to another file. how do i do it?

You can write get/set function and then using class pointer access those values in another file.
Somethings seem HARD to do, until we know how to do them.

is there any other way other than that?

If your classes support parent/child relationship then you can use GetParent() from your child class to access the members of the parent.
(P.S. - Is there some problem in getting the values as per my previous suggestion.)

there is no problem in doing so. but thought the other way where u make an instance of a class and pass the value thru that.

as a constructor parameter for instance...

Hi Experts,
How can I enumerate of all Bits of a Byte variable.
Thanx in advance.
|
|
|
|
|
try this
byte byValue = 12;<br />
byte byExtractor = 128;
for( int nIdx =0; nIdx < 8; nIdx ++ )<br />
{<br />
byte byBit = (byExtractor == (byValue&byExtractor));<br />
byExtractor = byExtractor>>1;<br />
std::cout<< "bit at "<<nIdx<<"th position is "<< byBit; <br />
}
|
|
|
|
|
|
Did you mean something like this? 
BYTE b = ???;
for( int i = 0; i < 8; i++ )
{
cout << (( b >> i ) & 0x1 ) << endl;
}

i want to use "Access" database to store my data, i just only know plain c(or Win32API), i can't use c++(or MFC), so how to read and write "Access" database files with C in Windows Programming(not MFC,C++)?

As far as I know ODBC still works and has a usable C interface. It's a whole technology wrapped in some Dlls so you'll need to look it up and try some examples but essentially it lets you open a database using a vendor supplied driver and run SQL queries against the database to form recordsets of results and then iterate over those result sets operating on individual rows. It's like a primitive version of OLE/DB without the need for COM.
Nothing is exactly what it seems but everything with seems can be unpicked.

I have a dll built from spidermonkey source. It also seems to build manifest file on winXP. Now my question is how do I load it in my client program. Apparently my winXP box is running .NET 2.0, and they have made it a requirement to load a dll ONLY through the manifest file dependency specification. Earlier it used to be as easy as dropping it in system32 folder, but now with .NET side-by-side assembly structure, things have changed 
Can anybody give me pointers as to how do I go about using that DLL in a C program (win32 console application) ?

I need to have a popup menu on the grid, but it doesn't look like it should. The main menu's text isn't shown, only a small blank menu, on the other hand the submenus show up and work properly if I position the cursor above the blank menu. Any idea? WinXP, VC 6.00 SP6
void CGridCtrlDemoDlg::OnGridRClick(NMHDR *pNotifyStruct, LRESULT* /*pResult*/)
{
NM_GRIDVIEW* pItem = (NM_GRIDVIEW*) pNotifyStruct;
Trace(_T("Right button click on row %d, col %d\n"), pItem->iRow, pItem->iColumn);
// To test popup menu
CPoint mypoint;
GetCursorPos(&mypoint);
pM = new CMenu();
pM->LoadMenu(IDR_POPUP);
pM->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON, mypoint.x,mypoint.y, AfxGetMainWnd());
}
|
|
|
|
|
you have to get submenu for show
like this:
pM = new CMenu();
pM->LoadMenu(IDR_POPUP);
CMenu* pSubMenu = pM->GetSubMenu(0);
pSubMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON, mypoint.x,mypoint.y, AfxGetMainWnd());
|
|
|
|

Thanks, but the submenus work just fine, the main menu doesn't show up. I have a popup menu item as the main menu, which shows up as a blank item, but if I position the mouse over it the submenu show up as it should.
Better idea?

First - let me apologize for posting this, but I am getting desperate and my posts in other forums went unanswered.
My development is OS Windows 2000 Advanced Server with 3 internal hard drives with various RAID 5 partitions. Just call me paranoid – I do not want to lose my code, period.
My problem is that my LCD freezes almost daily – no keyboard input, no mouse input.
The only way to recover is to turn the power off which upsets the RAID and on next power up it will faithfully regenerate all partitions.
The results are:
The system is painfully slow for few hours
The RAID regeneration cannot be stopped
My drives are wearing out
There are no real trouble indicator entries in the system log with the exception that the system was “shut down improperly”.
I am looking for any reasonable suggestions how to restore / recover from this little more gracefully.
PS
I run wireless keyboard / mouse with fresh batteries.
I test run another USB mouse and when this freeze-up happens it will disable that mouse too.
Please – no “update to hardware RAID / system xyz” suggestions.
Again - sorry for this off topic post.
Thanks for reading.
Cheers
Vaclav

Make sure your USB mouse/keyboard are not plugged in via your monitor or any other hub. Monitor hubs go on strike when the monitor goes into power save, very  .
USB is a mess internally and full of as yet improperly fixed bugs. If you're having problems get a PS2 keyboard and mouse and see if that helps. If so you've narrowed the problem to USB. If not then something else in the driver layer is sick. Try updated/recommended/backdated display drivers especially if you've go a newish NVidia card or a Dell PC. In the Dell case get the 'special' versions of the drivers off their website.
Good luck.

Matt, appreciate your comments.
I like your idea to fix the cause instead of trying to hack the RAID - it does exactly what it was designed do anyway.
My wireless interface goes to PS2 (keyboard) and motherboard USB (mouse).
I have a Dlink hub and I tried to run the USB thru it, but it fails pretty much same way.
I will go back to PS2 keyboard and keep the mouse wireless - for test.
In the meantime I will look for PS2 mouse in my junk box. Hi Hi.
But my main clue is – it only fails when the mouse is moved / clicked.
That would confirm your suspicion about lousy USB.
I have never seen the monitor to go to power save mode when it freezes.
Is there any way to log USB events in the log??
