Do not use LOWORD and HIWORD. Coordinates are signed values, LO/HIWORD treat the parameter as unsigned.

Hi All,
Could anyone tell me where to put the code for initialization for a new added dialog box in MFC application?
The InitInstance() is available only for the main window, inside which we can write code for initialization.But my problem is , where to write the code for a newly created dialog (if i want to do something when the dialog gets loaded)
Than u in advance

The right place is OnInitDialog [^].
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

What do you think about Constructor or WM_INITDIALOG?
Of one Essence is the human race
thus has Creation put the base

In MFC for every dialog there must be a class that's generated by the class wizard. Also it generates a function for this class called OnInitDialog, this function is called after the dialog and it's controls are created but not bound to data exchange member variables, which will be done when we call CDialog::OnInitDialog from our OnInitDialog.
There must be a comment in your OnInitDialog function which says
// Add your initialization code here
So after this call you can add your code for intialization.

Oopt!
where is your codes that generated these error ?
|

void *ptrList [30];
char ss [40];
for (i = 0; i<26; i++)
{
if (ptrList [i])
sprintf(ss, "%s", *(CString *) ptrList [i]);
}
What do those code do?
Thanks.

hung1984 wrote: if (ptrList [i])
sprintf(ss, "%s", *(CString *) ptrList [i]);
From the code...
ptrList is an array of CString pointers which for some reason is kept as void pointers, but the developer knows it's internally CString* so he is "confidently" casting it to CString* then copying the CString value to a character buffer (ss).
Confusing at times and also he forgot another step to cast *(CString*) to LPCTSTR and to use _stprintf instead of sprintf.
So after correction the code will look like...
void *ptrList [30];
char ss [40];
for (i = 0; i<26; i++)
{
if (ptrList [i])
{
LPCTSTR lpctszStr = (LPCTSTR)(*(CString *) ptrList [i]);
_stprintf(ss, "%s", lpctszStr);
}
}

sprintf(ss, "%s", *(CString *) ptrList [i]);
it's copying content of ptlist to ss!

what the statement for if here ?
if (ptrList [i])
|
|
|
|
|
You just only declare a array of void pointer like void* ptrList[30]; and no initialize for them.
so ptrList[i] point to a value that has no type (and thus also an undetermined length and undetermined dereference properties). ptrList[i] is now == 0x??????????
and if(ptrList[i]) is now similar if(true)
let me know if i am wrong

The program do a lot of hard disk reading and writing,
so other application became very slow,
any way to make it work when the hard disk is not busy?
|
|
|
|
|
My suggestion is to use Memory Mapped Files[^]. It will definitely improve the file access performance. You can use CMemMapFile[^] class for making your task easier.
Just try it and check whether the MemoryMapped files improves the performance in your case. Good Luck!

Jijo.
