How you r reading the values of the radio button, and which event you have trapped, is it double click.

Is it possible to create an Event within a Service (running under LocalSystem), and then signal that same event from another process (i.e. a normal process)?
I tried setting the security descriptor for the event to enable 'all access' to 'everyone', but it doesn't seem to work - GetLastError returns '5: access is denied'.
Is it the case that the event object is exclusively reserved for the service?

|
1. Yes, you can.
2. Perhaps you created the security data incorrectly.
3. No - we do this all the time.

Create a named event. then any process can open that event and signal or detect it.

Of course. The easiest way is to use SetWindowText(). But since you have a hangup with it, you'll need to use ReplaceSel(). To keep the insertion point at the "end" of the control, use SetSel().

Hi,
I am using the below two line to execute an crystal report file from VC++. I can't able to see my report(Report is not displayed). i also specified the destination to window in the crystal control properties.
m_CrystalReport.SetWindowTitle("Trucks Loaded Report");
m_CrystalReport.PrintReport();
How can it invoked in other ways.. Urgent
Give me a touch... Regards,

how to change background color of CRichEditCtrl?
includeh10
|
|
|
|
|
|
For other controls, the correct way would be with OnCtlColor(). However, I do not see a CTLCOLOR_xxx value for rich-edit controls.

there are 3 std* handles: stdin,stdout,stderr;
we can use GetStdHandle() with STD_INPUT_HANDLE,STD_OUTPUT_HANDLE,STD_ERROR_HANDLE as param to get 3 handles also.
what are differences between the 2 group handles?
i.e. between stdin and GetStdHandle(STD_INPUT_HANDLE)?
in my dos program, GetStdHandle(*)s work well but stdin, stdout and stderr do not work. do u know why?
thx

Which indicates that you are possibly using them incorrectly. Please post the code snippet that is not working.

Hi,
this dos app is an interface between other 2 apps, it is very short, here is all code:

This is one of those situations where stdin/stdout and a HANDLE type cannot be interchanged. Remember that stdin/stdout are derived from the _iobuf structure, and the handles returned from GetStdHandle() are true handles (void* types).

Hi there
I am working on a application that is supposed to create a dial up connection in order to connect two computers using the serial port (direct connection using the serial port). I can create the entry no problem but the problem i am running into is that it will not attach the serial port to it (by the way i am using RAS API)
I am setting the device type to serial but the com port is not attached to the connection created.
If i try to create the same connection using the wizard that is provided with Win XP than it gives me the option to select the serial port as a means of communication. Once i create this connection and i run my program i get the desired output so it looks like the COM ports need to be configured for RAS. Is there any way to do that programatically or run a script?
Any help will be greately appreciated!!!
<br />
<br />
<br />
LPRASENTRY lpRasEntry = NULL;<br />
DWORD cb = sizeof(RASENTRY);<br />
DWORD dwRet;<br />
DWORD dwBufferSize = 0;<br />
<br />
<br />
<br />
RasGetEntryProperties(NULL, "", NULL, &dwBufferSize, NULL, NULL);<br />
if(dwBufferSize == 0)<br />
return FALSE;<br />
<br />
lpRasEntry = (LPRASENTRY)HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, dwBufferSize);<br />
if (lpRasEntry == NULL)<br />
return FALSE;<br />
<br />
lpRasEntry->dwSize = dwBufferSize;<br />
lpRasEntry->dwfOptions = RasEntry.dwfOptions; <br />
lpRasEntry->dwfNetProtocols = RASNP_Ip;<br />
lpRasEntry->dwFramingProtocol = RASFP_Ppp;<br />
lpRasEntry->dwType = RASET_Direct;<br />
strcpy(lpRasEntry->szDeviceType, RASDT_Serial); <br />
<br />
<br />
strcpy(lpRasEntry->szDeviceName, ports[0].name);<br />
dwRet = RasSetEntryProperties(NULL, strEntryName,lpRasEntry, dwBufferSize, NULL, 0);<br />

Hi All,
I am using (Visual C++ 1.52 IDE )for my MFC Application Project. I am working on an existing code base where the no of lines is around 100,000, spread across different header and cpp files. when i was trying to add a new function declaration for an existing class in a header file and function implementation in the .cpp file i am getting an error as given below
: fatal error C1001: internal compiler error
(compiler file 'msc3.cpp', line 429)
CL returned error code 2.
in another .cpp file.
This problems also occurs when i try to add parameters to the existing function in an existing class
heap size is 1024 declared in .def file and i have set my stack size as 8500
Pls let me know if any one has solution to this problem
Thanks in advance
Regards
Senthil.

Hi
I am using a rih edit control in my SDK app. So when i was executing the app i got the "Cannot find window class" error when i tried to call CreateDialog(..).
So i did the following
INITCOMMONCONTROLSEX init;
memset(&init, 0, sizeof(init));
init.dwSize = sizeof(INITCOMMONCONTROLSEX);
init.dwICC = ICC_STANDARD_CLASSES;
InitCommonControlsEx(&init);
Now i get an error that 'ICC_STANDARD_CLASSES' : undeclared identifier even when commctrl.h and comctl32.lib are properly used.
|

|

Per MSDN, ICC_STANDARD_CLASSES is not a valid option.
Prior to creating the control, I think you might need to call LoadLibrary("riched20.dll").

The rich edit control is initialized differently than other controls. You need to load either riched32.dll or riched20.dll in your app's init code, depending on which rich edit version you need.
