Hi ,
Yes I am using CResizingDialog . Now what i did is i have writte a message handler
MESSAGE_HANDLER( WM_SIZE, OnSize )
but i didnt provide its implementation. My class is derived from CResizingDialog . Now buttons are changing their position as i required. But still not understood how it is working. Is it calling CResizingDialog :: OnSize () in this case ..?

Hi All

If you plan to have controls on your dialog and resize or move them based on the size of the dialog you may want to use a layout library like this one: CResizableDialog[^]

Have you looked at SetWindowPos() or MoveWindow()?

I've got an old project writetd in vc++ on VS 7.1. When I opened it on Visual Studio 2008 it was correctly converted and worked. Now i needed to use a part of this old code in the new project created on VS2008. Everything work exepct a part of old code:
int CDGabinetDlg::DefineGrammar(const char* fn)
{
int rc;
SM_MSG reply;
TCHAR lpBuffer[256];
GetCurrentDirectory(256, lpBuffer);
string filename(lpBuffer);
filename+="\\";
filename+=fn;
return rc;
}
I've get an error in this part:
string filename(lpBuffer);
This is an error what i get.
error C2664: 'std::basic_string<_Elem,_Traits,_Ax>::basic_string(const std::allocator<_Ty> &)' : cannot convert parameter 1 from 'TCHAR [256]' to 'const std::allocator<_Ty>

The difference between VC7 and VC8 (related to your error I mean) is that in VC2008, UNICODE is defined by default. If you want to better understand what that means, I suggest this article[^].
In your code snippet, you are not being consistent neither: sometimes you are using a char arrays, sometimes a TCHAR array. So, either you do not care at all about unicode and only use char array, or you care about UNICODE and use TCHAR arrays everywhere. But using both is ugly.
On the other hand, std::string do not support wide characters, so that's why you have the compilation error. For that part, if you want to support unicode builds, I suggest you define your own type:
#if defined _UNICODE || defined UNICODE
typedef std::wstring TMyString;
#else
typedef std::string TMyString;
#endif
This way, you'll be independant of the unicode settings.

Hey, I wanted to know that whether it is safe to use ADO in a DLL? The reason I'm asking this is that, to use ADO we need to initialize COM right? So calling CoInitialize in a DLL, is it okay?

Yes. You do it and the matching uninitialize in DLLMain for every Process and Thread attach/detach message.
From the documentation:
Because there is no way to control the order in which in-process servers are loaded or unloaded, do not call CoInitialize, CoInitializeEx, or CoUninitialize from the DllMain function.

What do you mean? Is it safe? Will there be any malfunction?

That depends on you, your analysis of your scenario and developing a correct solution. Make sure you read the documentation I provided a link to.
The best scenario is the host process has already handled COM initialization. If that isn't happening then you have a less than perfect scenario. Make sure you understand the ramifications and develop the proper error handling code for the potential scenarios that could occur based on your hosting scenario.
My fault, I should have mentioned that your scenario can also call for dealing with the initialization in other exports of your DLL rather than DLLMain. The problem with that is you need to account for the messages you get passed in DLLMain so that you know which event is happening. It's really up to you to figure all this out based on your project details.

Well now, I guess I would have to use another solution.
Thanks anyways

GetDlgItemText(id)->EnableWindow(FALSE) is not working in windows vista OS when user admin is off.I want to disable a groupbox in vista OS.
|
|
|
|

Do you want to disable the group box window? Why? After all its a static control
Or the controls within it?
You need to google first, if you have "It's urgent please" mentioned in your question.

Hi All

You may perform the processing in a worker thread while displaying the wait message in the main (GUI) one, see [^].

Why don't you just let the user do his thing when the report is being prepared, instead of showing a 'plz wait' message? Just use a worker thread to prepare the report.

Why would you want the user to wait if the GUI is not blocked?

I have a dialog which consists of 2 list control items set in report view.
I wish to color a row in one of the list control.
How can i do it?
I can do it, if the app is Single Doc with base class CListView, by using OnCustomDraw.
But how can i implement OnCustomDraw in one of the List Control from dialog?
