you're right, i typed from my head...
fixed now.
|
|
|
|
|
|
for example:
dlg.SendMessage(WM_SIZE,SIZE_MAXIMIZED,0);
you can try this.

I want to use Updatedata() in Thread function
I write the code below but compile error
UINT Thread1(LPVOID pParam)
{
CTestDlg *m_dlg = (CTestDlg*)pParam;
UpdateData(TRUE);//error
AfxMessageBox(m_dlg->m_edit);
return TRUE;
}
|
|
|
|
|
Max++ wrote: UpdateData(TRUE);//error
good...
now, can we know the error message ?! 
|
|
|
|
|
First, it would be nice that you provide ALL the information, that is also the error message.
In your case I suppose the problem was because UpdateData was not recognized and that's logical because UpdateData is a function from a CDialog class and your thread function is a global function. And also, it is a very bad idea to 'update' data inside another thread than the main thread (the one that manages the GUI). Instead, send a user defined message to your dialog class so that, upon receiving this message, you can update your data inside the main thread.
|
|
|
|
|
Maybe instead of
UpdateData(TRUE);
you should try this:
m_dlg->UpdateData(TRUE);
I hope this helps. Note that not all of MFC functions can be used from different threads.

i don't think m_dlg is visible, as used within a global function...

In the original code m_dlg it is a local variable defined and initialized inside the function.

oh, i didn't look much  you're right...
but bad naming convention then !!!
|
|
|
|
|
It is passed as a parameter to the thread function (at least, it looks like). But anyway, it is a very bad idea to call this function from within another thread.

I want to paint some bitmaps for the Title bar and the Menu bar in a MFC application. How can we get the dimensions of the title bar or menu bar so that we could paint it accordingly?
I searched MSDN and it told I could use the call GetTitleBarInfo() for info on the title bar. But, the type of the parameter passed PTITLEBARINFO is not defined in Windows. Can anyone help me out?
Thank you,
AJ

I saw this on the MSDN, but if you try to use it with Microsoft Visual C++ 6.0, it gives a compilation error saying that TITLEBARINFO in undefined.
Thanks

I found the solution....the WINVER has to be defined as 0x0500 for 98, 2000 or later. After this it compiles without errors....

I posted here yesterday for this weird problem I am facing in MFC but I haven't got any replies in this forum. The problem - I have added an MFC class to my automation enable MFC "Full Server". While Adding the class, I selected the base class to be CCmdTarget and Selected the "Creatable by TypeId" option. The wizard generated the code but when I tried registering my server, the registry entry for this particular Class was NOT created in registry for some reason.
Finally, I have figured out the issue to be following -
The wizard adds IMPLEMENT_OLECREATE_FLAGS macro instead of IMPLEMENT_OLECREATE macro. If I change the wizard generated code to use IMPLEMENT_OLECREATE my class is getting registered. What I don't understand is why the wizard generated code is not working!!! (After looking at the macro code, I realize that it should work)
Does any one out here know about this issue? I am using VS .NET 2003

Use SetWindowsHookEx() to set up a WH_KEYBOARD hook. Return a nonzero value from the your hook procedure to kill the keystroke.

how many arguments we can pass to the new process?
Is there any limit on arguments or the size of buffer
that we are giving to CreateProcess as second parameter??

lpCommandLine
[in, out] Pointer to a null-terminated string that specifies the command line to execute. The maximum length of this string is 32K characters.
Windows 2000: The maximum length of this string is MAX_PATH characters.
The Unicode version of this function, CreateProcessW, will fail if this parameter is a const string.
The lpCommandLine parameter can be NULL. In that case, the function uses the string pointed to by lpApplicationName as the command line.
If both lpApplicationName and lpCommandLine are non-NULL, the null-terminated string pointed to by lpApplicationName specifies the module to execute, and the null-terminated string pointed to by lpCommandLine specifies the command line. The new process can use GetCommandLine to retrieve the entire command line. Console processes written in C can use the argc and argv arguments to parse the command line. Because argv[0] is the module name, C programmers generally repeat the module name as the first token in the command line.
If lpApplicationName is NULL, the first white-space – delimited token of the command line specifies the module name. If you are using a long file name that contains a space, use quoted strings to indicate where the file name ends and the arguments begin (see the explanation for the lpApplicationName parameter). If the file name does not contain an extension, .exe is appended. Therefore, if the file name extension is .com, this parameter must include the .com extension. If the file name ends in a period (.) with no extension, or if the file name contains a path, .exe is not appended. If the file name does not contain a directory path, the system searches for the executable file in the following sequence:
The directory from which the application loaded.
The current directory for the parent process.
The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory.
Windows Me/98/95: The Windows system directory. Use the GetSystemDirectory function to get the path of this directory.
The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is System.
The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
The directories that are listed in the PATH environment variable.
The system adds a null character to the command line string to separate the file name from the arguments. This divides the original string into two strings for internal processing.

A simple example:
I have a non-mode dialog ,and there are one Button, one ListBox in it.
Aim:
When the ListBox is empty the Button state is Disable, otherwise is Enable. And I want to use ON_UPDATE_COMMAND_UI message to do it.
Thanks very much!
