Does anybody know the code for C++ 6.0 to allow it to search for a certain character in a sentence.
Ex: My name is Mike
Search for character M:
If found it tell me how many you found
If didn't found it tell me cannot find.
Thanks

CString::Find does some of the work for you.

?
Any ideas? Any code? I can use the arrow keys, but
how can I use the tab key to navigate through a
MsFlexGrid control?
Please, please, any response any one can give me will
be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

I don't know about MsFlexGrid,but in CP there are nice grids,check them,maybe they are useful for this task.

under MDI, an icon IDR_MAINFRAME is created. how can i load it to the mainframe so that when execute the program, the icon i created can appear on the mainframe?
can this bedone too for childframe?
|
|
|
|
|
In the InitInstance() of your application find this lines:
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
In place of "IDR_MAINFRAME" you can put yuor own icon.

t've tried this earlier on. but unsuccessful. does the OS affect the way the application works? i am now programming under XP OS.
it seems to me that when i change the IDR_MAINFRAME in the resource, it will still load the default MFC icon. how do i associate the icons i created to the project?

once you create your icon, save it to your resource directory. Then from the resource view tab, select IDR_MAINFRAME, then right click. A popup menu will show then select properties and you should see the properties dialog for IDR_MAINFRAME. The edit box at the bottom labeled file name needs to point to the path of the new icon in your resource directory. Close the dialog then your icon will be associated with IDR_MAINFRAME.

I think there is a bug in the autogenerated code, so if you try modifying your PreCreateWindow function to look like below, it should work.
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
return TRUE;
}

Please, help me! I have external device, which connects with comm-port.
I send to device the number, after it signaled it send to computer some signal;
how can i receive this signal? in case, if device is nonsignaled, how can i wait
it for five sec, and break the waiting operation?
What do i need to write to this code, in the end of it?
I know all abot WaitCommEvent and WaitForSingleObject, but i don't know
how to use it. WaitForSingleObject doesn't work with EVENT, or i don't know
how to use it
HANDLE port;
DWORD bc;
DCB dcb;
char buffer[100];
char *buf_out="50";
DWORD dwBlockSize=512;
void *szBuffer;
int send=255;
ZeroMemory(&dcb,sizeof(DCB));
strcpy(buffer,"baud=1200 parity=N data=8 stop=1");
BuildCommDCB((char*)&buffer,&dcb);
dcb.fRtsControl = RTS_CONTROL_ENABLE;
port=CreateFile("COM1",
GENERIC_READ|GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
GetCommState(port,&dcb);
SetCommState(port,&dcb);
HeapFree(GetProcessHeap(),0,&dcb);
szBuffer = malloc(dwBlockSize);
memset(szBuffer, send, dwBlockSize);
// Sending number for device
WriteFile(port,szBuffer,sizeof(szBuffer),&bc,NULL);
free(szBuffer);
// Wait for signal for five sec
CloseHandle(port);

(1) Init an event by using CreateEvent()
(2) Add in OVERLAPPED struct to your code
(3) Insert the event (1) into (2)
(4) CreateFile() with FILE_FLAG_OVERLAPPED
Now call WaitCommEvent() with LPOVERLAPPED = (2) whereever you want. Wenn the specified com-event occurs the event (1) will be set to signaled state. You should wait for it with WaitForSingleObject() in a seperate thread.

Hi. Does anyone know how to check if a printer is actually connected before sending anything to it. I am sending things to the printer automatically after so often. However, if nothing is connected, I want to not do it.
THanks in advance.
|
|
|
|
|
As I know, OpenPrinter doesn't check if printer is really connected. EnumJobs tries to talk with printer and fails if it is not connected. If printer is not local and it's network computer doesn't respond, call to EnumJobs may take number of seconds, as any network call.

I want to play two mpeg files simultaneously, just as picture in picture(the small one overlay the big one). I used two mediaplayer ActiveX controls. How can I accomplish that?
Thanks for advice in advance.

I don't know if this could help you because I do it in VC7 but try to do this , it may help
you: (you can do for both of your ActiveX)
*In property page of them set the "AutoStart" property to "false".
*Set the "FileName" the path of your file.
*You can use "play()","stop()","pause()" function in your code.
I could not find any function for changing "FileName" property

What would be the appropriate terminology for the opposite of fence post/stack overflow, out of bounds checking...?
In my code I check for overflow of 'My' stack and underflow??? when going in the opposite direction.
Does this sound right? For some reason i'm thinking theres a cooler term like reciprocal correction or something...
ANy ideas?

Use strcmp to compare to strings.
int StrCmp(
LPCTSTR lpStr1,
LPCTSTR lpStr2
);
Parameters
- lpStr1
- [in] Pointer to the first null-terminated string to be compared.
- lpStr2
- [in] Pointer to the second null-terminated string to be compared.
Return Values
Returns zero if the strings are identical. Returns a positive value if the string pointed to by lpStr1 is greater than that pointed to by lpStr2. Returns a negative value if the string pointed to by lpStr1 is less than that pointed to by lpStr2.
Remarks
This function returns the difference in value of the first unequal characters it encounters, or zero if they are all equal. For example, if lpStr1="abczb" and lpStr2 = "abcdefg", StrCmp determines that "abczb" is greater than "abcdefg" and returns z - d.
This is how you would determine if one string should go before or after another string, then you could write your own sorting algorithm, or you could use the sort function in STL.
