We have developed one project in which we have to sort out the fields based on filter condition. The project should be similiar to the one we have in the excel sheet. The first Row in data grid control will be static and we cannot edit anything in that. It actually has the column names from the database. But the filter condition has to be placed there. A dropdown box should appear when we click that column name and the unique values residing under that column has to be displayed. The rows in the grid has to be refreshed according to the filter condition we applied.
please let me know the ways in which it can be implemented. please give me the source code if possible.

by using RegNotifyChangeKeyValue() ,we can notify the changes,then how i can capture the changed key name ,value,status i used RegQueryValueEx(),
i got some garbage value like iiiiiiiiiiiiiiiiii.
Any one give idea about how to capture the name after identifying the notification.
Thanks

show the code you are using to capture the change of a key name, and we will see why you get a garbage....

Hi Yaron,
I want to monitor the changes in the registry,By selecting on of the Root key then monitor the changes in that inlcude key,subkeys.....for name,value and status.
i Add the code in the thread function for monitoring as belowvoid
MonitorThread(void* pParam)<br />
{<br />
DWORD dwFilter = REG_NOTIFY_CHANGE_LAST_SET, dwType, dwSize ;<br />
char lpszUser[81];<br />
HANDLE hEvent;<br />
HKEY hKey;<br />
LONG lErrorCode;<br />
<br />
while(1) {<br />
m_Sec.Lock();<br />
dwSize = 81;<br />
dwType = REG_SZ;<br />
<br />
lErrorCode = RegOpenKeyEx(hKey, NULL, 0,<br />
KEY_NOTIFY | KEY_READ, &hKey);<br />
<br />
hEvent = CreateEvent(NULL, TRUE, FALSE, NULL);<br />
<br />
lErrorCode = RegNotifyChangeKeyValue(hKey, TRUE, dwFilter, hEvent,TRUE);<br />
<br />
WaitForSingleObject(hEvent, INFINITE);<br />
<br />
lErrorCode = RegQueryValueEx(hKey,NULL,0,&dwType,(unsigned char*)lpszUser,&dwSize);<br />
<br />
int item=pList->InsertItem(pList->GetItemCount(),lpszUser);<br />
lErrorCode = RegCloseKey(hKey);<br />
<br />
m_Sec.Lock();<br />
CloseHandle(hEvent);<br />
}<br />
<br />
<br />
<br />
}
For reading root key i put one combo box in the dialog and selecting one root key by pressing start button starts the monitoring ,if any changes occurs in the that rootkey registry display that key name,value ans status(create/modify/delete).
by pressing stop button stops the monitoring
Thanks,
Kiran.V

I am not sure what you mean by that but if you are talking about physical memory management then look into Address Windowing Extensions provided in Win API. It lets you lock in some pages in physical memory, for example, when you do OS-level optimization of your algorithms working with reasonably large data sets.

How to improve the resolution of a bitmap in a .bmp file. When I print the bitmap, its resolution is not good.
Can anyone suggest me some code to improve its resolution???
aasstt

|

The only reason i can think of that your bitmap resolution is not good, is because you strech it even not intently.
make sure when you blit the bitmap, that the cx and cy are correct (meaning you got them right using the GetBitmapDimentions method)....

I have created a compatible DC of the printer DC and then I have Converted DDB to DIB. Then I have written this DIB in a .bmp file. but when I open this file in Paint & give its print its resolution is not good.

Can you be more specific.
|

I have created a compatible DC(MemDC) of the printer DC.
Then MemDC->SelectObject(bitmap)
Then whatever I draw on the screen is drawn in memory.
and then I have Converted this bitmap from DDB to DIB.
Then I have written this DIB in a .bmp file. but when I open this file in Paint & give its print its resolution is not good i.e it is not appearing as a smooth image but an image with steps in it.

aasstt,
I dont know your code but I use handle printer dc and I created bitmap
or I load bitmap from file and then print and resolution isnt bad.
Now you have bitmap from file or you created bitmap inside your program
|
|
|
|
|
I have created the bitmap and then written that bitmap using the WriteDIB function(which I have downloaded from codeproject)in a .bmp file.

if you have bitmap(that you created) why you directly print instead save to file and again loaded?if it has handle HBITMAP

Of course 
use the ParseCommandLine method, in your InitInstance of your CWinApp derived class...
from there it's easy

Hi Yaron,
What do you mean?
Do you want that you want to use the Media player inside your application and not as a seperate window?
