The CDateTimePickerCtrl uses the SYSTEMTIME structure for it’s time. Getting it goes a little something like this:
CDateTimePickerCtrl dtp(GetDlgItem(IDC_DATETIME1));<br />
SYSTEMTIME st;<br />
Dtp.GetSystemTime(&st);
If your using it with the SHOW NONE property you can check the return value of GetSystemTime() making sure it returns GDT_VALID, if it’s GDT_NONE then the checkmark is cleared. If you want to use WTL::CTime add #include <atltime.h> to your stdafx.h and you can pass the SYSTEMTIME to it’s constructor and bam. CTime from a CDateTimePickerCtrl.
CDateTimePickerCtrl dtp(GetDlgItem(IDC_DATETIME1));<br />
SYSTEMTIME st;<br />
Dtp.GetSystemTime(&st);<br />
CTime t(st);

I have my small program which creates process, but now i want to manipulate more than one process at a time. Is that possible? Like i have created a notepad process and later while notepad is running i create another process cmd.exe, can i suspend them all one after the other or shut them consecutively maybe by specifying process id,s or handles
-oam-

Aww man you can do all kinds of rad things with processes. Pretty much everything that Task Manager can do you can do. What you want to do is call CreateProcess() and pay attention to the last argument, a PROCESS_INFORMATION structure which has the hProcess handle. With that your free to call functions like TerminateProcess() and SuspendThread(). However TerminateProcess() is pretty drastic and does not guarantee that anything will be freed and the process may need to run critical cleanup code. TerminateProcess() is like shutting a program off by unplugging the power. You could see if a process is associated with a window by calling EnumWindows() and comparing the ProcessId, which you can get from GetWindowThreadProcessId().

You code looks fine, your passing the handles of the process and thread from the PROCESS_INFORMATION structure that gets filled out when you call CreateProcess(). Perhaps make sure that these calls are succeeding by checking the return values. If you wanted to keep track of more then one process then you could use a container class like MFC's CArray or CList or STL's vector or list.

I don't have any idea about MFC arrays because i am using C unless if they can work in c code. But i have no idea with MFC or CList nor STL vector. You can give me a go ahead or segment code to handle it

I’m going to save and load an XML-file in an SQL server. I really like suggestions on how to tackle the problem. My application is an MFC C++ project.

I use checker = atoi( (LPCTSTR)str) to convert CString to int and checker to check if the number typed in CEdit box is within valid range.
Now the problem is when user type a number then follow by letters. 1234abcd would return checker as 1234. How would I go about checking for non-integer characters?
Or is there anyway to limit user to only type in integers?

edit controls have a "number only" property. check for it in the resource editor / property viewre.

One good way to parse your strings is to use _stscanf like so:
int a;
CString mytext = _T("123Hello");
if(_stscanf(mytext, _T("%d"), &a) != 1)
{
}

hey everyone
i have this project i need to do that uses setwindowshookex to set a message hook on a given process ID and for each keydown that that screen gets i replace the key with the char from a given text file
so like
the procces ID is notepad and the file is Omri.txt witch has
"Hello World" in it
so if i type in notepad "asdasdasd" it will type "Hello Wor"
anyway, thats the project
so what i did is make a DLL with the functions
open file
close file
get char
set hook
unhook
and getkeys
getkeys is the function windows calles when a key is pressed
so my problem is, when windows calles the function it cant access the opened file becuse it gets a difrent data field
i tryed puting the fstream var in shared memory but it didnt help
anyone here got any idea on how i shold do this?

Hi, everybody,
I develop a browser helper object. I need to update the address in the address bar to a different address after user navigates to it. I tried to handle the NavigateComplete event but failed to make change to the address. Any change that makes to the address causes crash in IE. How can I solve this problem?
Thanks.

but in this i have to pass handle of file, i want to use name of file to get size.
or i can use handle of file if i get to know handle of file(is there any function from which i get handle of file)
bye
|
|
|
|

You can use the FindFirstFile API to get this info!
Don't try it, just do it!

Yes, CreateFile().

I'm trying to use a binary resource in my executable, but I'm not having any luck.
I've looked all over MSDN and the web, and I've found nothing that gives clear instructions on how to do this.
Anyone got any hints/tips?

If by binary you mean RT_RCTYPE, check out this article.

For each file you want to include, add a line to resource.h as follows:<br />
<br />
#define IDR_MYFILE 103<br />
<br />
Remember to give each file a unique resource ID.<br />
<br />
Close all resource files and open your .rc file as "text." Add the line<br />
<br />
IDR_MYFILE RCDATA DISCARDABLE "res\\myfile.ext"<br />
<br />
A good place to add this line is immediately after the line which defines the IDR_MAINFRAME icon. If you haven't placed "myfile.ext" in your "res" subdirectory, adjust the path accordingly. Save the .rc file. Close it and open ResourceView. You should see something like this:<br />
<br />
There are more convenient ways of inserting a custom data resource, but they either embed the file as raw hex data in the .rc file, inflating it to several times the size of the included file, or neglect to define the resource ID in resource.h so that ResourceView shows the ID in inverted commas.<br />
<br />
To turn a resource back into a file, load it into memory using LoadResource(). This returns a BYTE pointer that CFile can use to write that file to disc.<br />
<br />
// Load the resource and save its total size.<br />
HRSRC hRes = FindResource(NULL, MAKEINTRESOURCE(IDR_MYFILE),RT_RCDATA); <br />
DWORD dwSize = SizeofResource(NULL , hRes);<br />
HGLOBAL MemoryHandle = LoadResource(NULL, hRes);<br />
if(MemoryHandle != NULL)<br />
{<br />
// LockResource returns a BYTE pointer to the raw data in<br />
// the resource<br />
BYTE *MemPtr = (BYTE *)LockResource(MemoryHandle);<br />
CFile file("C:\_my_path_to_file\myfile.ext", CFile::modeCreate | CFile::modeWrite);<br />
file.Write(MemoryHandle,dwSize);<br />
}<br />
FreeResource((HANDLE)hRes);<br />
<br />
